CHICAGO – Declining androgen levels are associated with deteriorating physical function and increased frailty in aging men, according to a study presented at the annual meeting of the Endocrine Society.

The findings provide more evidence of the relationship between function and lower levels of androgens such as testosterone and introduce the possibility of using hormones to offset frailty in older patients.

“The decline in total and free [testosterone] and DHEA-S [dehydroepiandrosterone sulfate] was significantly associated with small deteriorations in physical function and worsening frailty,” according to presenter Frederick C. Wu, MD, an endocrinologist at the University of Manchester (England). “The present results are consistent with and support our hypothesis that the decline in these hormones can contribute to a worsening physical function and frailty in the elderly.”

Investigators gathered data on 2,278 men from eight centers across Europe to conduct an observational study of their physical functions.

Patients were all men, an average of 58 years old, and had an average body mass index of 27.6 kg/m² and average free testosterone and DHEA-S levels at 16.9 nmol/L and 4.7 micromol/L, respectively.

At follow-up, which was on average conducted 4.4 years later, average age was 63 years, and average testosterone and DHEA-S levels had dropped to 287.3 nmol/L and 4 micromol/L respectively, which Dr. Wu described as a moderate drop.

Decreases of free testosterone or DHEA-S by one standard deviation – 86.8 nmol/L and 2.6 micromol/L, respectively – accounted for 11%-17% of the average rate of deterioration of physical function, according to Dr. Wu.

Patients with lower levels of free testosterone and DHEA-S experienced worsening 15-meter walk time, five chair-stands, physical quality of life, and overall worsening of frailty phenotypes at follow up.

Dr. Wu and his colleagues measured frailness in patients by looking for the presence of frailty phenotypes, which include slowness, sarcopenia, exhaustion, low activity, and weakness.

If one-two of these criteria were present, patients would be considered “prefrail,” and if three or more were present, patients would be deemed “frail.”

Patients experienced an average 2.5% increase in frailty per year during the time between baseline and follow up, Dr. Wu told attendees.

Investigators used the mean of 60 years old to adjust for age, Dr. Wu explained in response to a question from the audience; however, this may have been an overadjustment as free testosterone and DHEA-S are age dependent, Dr. Wu admitted.

Investigators also incorporated a frailty index of 39 health deficits – 16 physical or cognitive, 11 comorbidities, and 12 clinical – measuring on a 0-1 scale in order to measure different levels of frailty.

While the link between these androgens and frailty are evident, the potential benefits of hormonal intervention in elderly men are still in the air and demand further study.

“The decline in androgen levels in the physiological range, because of the modest degree of change, is unlikely to be the single greatest cause of deterioration in the majority of aging men in the population,” said Dr. Wu. “Therefore, the possible therapeutic roles of androgens in improving physical health may be limited to a minority of men with very low levels of testosterone.”

The accountable care organization (ACO) concept, elucidated in 2006 as the development of partnerships between hospitals and physicians to coordinate and deliver efficient care,¹ seeks to remove existing barriers to improving value.² Some advocate this concept as a promising payment model that could successfully realign the current payment system to financially reward improvements in quality and efficiency that bend the cost curve.^3,4 Hospitalists fit well with this philosophy. As the fastest growing medical specialty in the history of American medicine, from a couple of thousand hospitalists in the mid-1990s to more than 50,000, the remarkable progression of hospitalists has ostensibly been driven partially by hospitals’ efforts to improve the value equation through enhanced efficiency in inpatient care. Importantly, hospitalists probably provide care for more than half of all hospitalized Medicare beneficiaries and increasingly patients in skilled nursing facilities (ie, SNFists).⁵ Along with primary care physicians, hospitalists thus represent an essential group of physicians needed to transform care delivery.

When the Affordable Care Act (ACA) established the Medicare Shared Savings Program (MSSP), ACOs leaped from being an intellectual concept^1,2 into a pragmatic health system strategy.^3,4 Following Medicare, various private health insurance plans and some state Medicaid programs entered into contracts with groups of healthcare providers (hospitals, physicians, or health systems) to serve as ACOs for their insured enrollees.⁶ Leavitt Partners’ ACO tracking database showed that the number of ACOs increased from 157 in March of 2012 to 782 in December of 2015.⁷

Until recently, the federal government’s commitment to having 50% of total Medicare spending via value-based payment models by 2018, coupled with endorsement from state Medicaid programs and commercial insurers, demonstrated strong support for continuation of ACOs. Unexpectedly on August 15, 2017, the Centers for Medicare & Medicaid Services (CMS) outlined a plan in its proposed rulemaking to cancel the Episode Payment Models and the Cardiac Rehabilitation incentive payment model, which were scheduled to commence on January 1, 2018. CMS also plans to scale back the mandatory Comprehensive Care for Joint Replacement (CCJR) bundled payment model from 67 selected geographic areas to 34. Although this proposed rulemaking created some equipoise in the healthcare industry regarding the future of value-based reimbursement approaches, cost containment and improved efficiency remain as major focuses of the federal government’s healthcare effort. Notably, CMS offers providers that are newly excluded from the CCJR model the opportunity to voluntarily participate in the program and is expected to increase opportunities for providers to participate in voluntary rather than large-scale mandatory episode payment model initiatives. In 2018, the agency also plans to develop new voluntary bundled payment models that will meet criteria to be considered an advanced alternative payment model for Quality Payment Program purposes.

Importantly, the value-based reimbursement movement was well underway before ACA legislation. Through ACA health reform, value-based reimbursement efforts were expanded through ACOs, bundled payments, value-based purchasing, the CMS Innovation Center and other initiatives. With health systems having an overflowing plate of activities, a wait-and-see attitude might seem reasonable at first. However, being unprepared for the inevitable shift to value-based reimbursement and reduced fee-for-service revenue places an organization at risk. A successful ACO requires system-level transformation, especially cultural and structural changes to achieve clinical integration. Being embedded in health system delivery, hospitalists can help shape a team-oriented culture and foster success in value-based payment models. This requires hospitalists to take a more active role in assessing and striking a balance between high-quality, cost-efficient care and financial risk inherent in ACO models.

The key to hospitalists fulfilling their value creation potential and becoming enablers for ACO success lies in developing a thorough understanding of the aspects of an ACO that promote efficient and effective care, while accounting for financial factors. Fundamentally, the ACO concept combines provider payment and delivery system reforms. Specifically, the definition of an ACO contains 3 factors: (1) a local healthcare organization (eg, hospital or multispecialty group of physicians) with a related set of providers that (2) can be held accountable for the cost and quality of care delivered to (3) a defined population. While the notion of accountability is not new, the locus of accountability is changed in the ACO model—emphasizing accountability at the level of actual care delivery with documentation of quality and cost outcomes. The ACO approach aims to address multiple, frequent, and recurring problems, including lack of financial incentives to improve quality and reduce cost, as well as the negative consequences of a pay-for-volume system—uncoordinated and fragmented care, overutilization of unnecessary tests and treatments, and poor patient experience all manifested as unwarranted geographic variation in practice patterns, clinical outcomes, and health spending. Participants in an ACO are rewarded financially if they can slow the growth of their patients’ healthcare costs while maintaining or improving the quality of care delivered. To succeed in this ACO world, hospitalists must assume greater prudence in the use of healthcare services while improving (or at a minimum, maintaining) patient outcomes, thus excising avoidable waste across the continuum of care.

More than half of ACOs include a hospital.⁸ However, whether hospital-led ACOs possess an advantage remains to be elucidated. Early reports indicated that physician-led ACOs saved more money.^9,10 However, others argue that hospitals¹¹ are better capitalized, have greater capacity for data sharing, and possess economies of scale that allow them to invest in more advanced technology, such as predictive modeling and/or simulation software. Such analytics can identify high-cost patients (ie, multiple comorbidities), super utilizers and populations lacking care, allowing ACOs to implement preventive measures to reduce unnecessary utilization. Recently released CMS MSSP 2016 performance data¹² showed that nearly half (45%) of physician-only ACOs earned shared savings, whereas 23% of ACOs that include hospitals earned shared savings. However, among all the ACOs that achieved savings, ACO entities that include hospitals generated the highest amount of shared savings (eg, Advocate, Hackensack Alliance, Cleveland Clinic, and AMITA Health). Notably, hospital-led ACOs tend to have much larger beneficiary populations than physician-led ACOs, which may create a scenario of higher risk but higher potential reward.

The emphasis on value over volume inherent in the development of ACOs occurs through employing care strategies implemented through changes in policies, and eventual structural and cultural changes. These changes require participating organizations to possess certain key competencies, including the following: 1) leadership that facilitates change; 2) organizational culture of teamwork; 3) collaborative relationships among providers; 4) information technology infrastructure for population management and care coordination; 5) infrastructure for monitoring, managing, and reporting quality; 6) ability to manage financial risk; 7) ability to receive and distribute payments or savings; and 8) resources for patient education and support.^2,3,13-16 Table 1 summarizes the broad range of roles that hospitalists can serve in delivering care to ACO populations.^17-19

Hospitalists’ active pursuit of nonclinical training and selection for administrative positions demonstrate their proclivity to provide these competencies. In addition to full-time clinician hospitalists, who can directly influence the delivery of high-value care to patients, hospitalists serve many other roles in hospitals and each can contribute differently based on their specialized expertise. Examples include the success of the Society of Hospital Medicine’s Leadership Academy; the acknowledged expertise of hospitalists in quality improvement (QI), informatics, teamwork, patient experience, care coordination and utilization; and advancement of hospitalists to senior leadership positions (eg, CQO, CMO, CEO). Given that nearly a third of healthcare expenditures are for hospital care,²⁰ hospitalists are in a unique position to foster ACO competencies while impacting the quality of care episodes associated with an index hospital stay.

Importantly, hospitalists cannot act as gatekeepers to restrict care. Managed care organizations and health maintenance organizations use of this approach in the 1990s to limit access to services in order to reduce costs led to unacceptable outcomes and numerous malpractice lawsuits. ACOs should aspire to deliver the most cost-effective high-quality care, and their performance should be monitored to ensure that they provide recommended services and timely access. The Medicare ACO contract holds the provider accountable for meeting 34 different quality measures (Supplemental Table 1), and hospitalists can influence outcomes for the majority. Especially through hospital and health system QI initiatives, hospitalists can directly impact and share accountability for measures ranging from care coordination to implementation of evidence-based care (eg, ACE inhibitors and beta blockers for heart failure) to patient and family caregiver experience.

Aligned with Medicare ACO quality measures, 5 high-impact target areas were identified for ACOs²¹: (1) Prevention and wellness; (2) Chronic conditions/care management; (3) Reduced hospitalizations; (4) Care transitions across the fragmented system; and (5) Multispecialty care coordination of complex patients. One essential element of a successful ACO is the ability to implement evidence-based medical guidelines and/or practices across the continuum of care for selected targeted initiatives. Optimizing care coordination/continuum requires team-based care, and hospitalists already routinely collaborate with nurses, social workers, case managers, pharmacists, and other stakeholders such as dieticians and physical therapists on inpatient care. Hospitalists are also experienced in facilitating communication and improving integration and coordination efficiencies among primary care providers and specialists, and between hospital care and post-acute care, as they coordinate post-hospital care and follow-up. This provides an opportunity to lead health system care coordination efforts, especially for complex and/or high-risk patients.^22,23 CMS MSSP 2016 performance data¹² showed that ACOs achieving shared savings had a decline in inpatient expenditures and utilization across several facility types (hospital, SNF, rehabilitation, long term). Postacute care management is critical to earning shared savings; SNF and Home Health expenditures fell by 18.3% and 9.7%, respectively, on average. We believe that hospitalists can have more influence over these cost areas by influencing treatment of hospitalized patients in a timely manner, discharge coordination, and selection of appropriate disposition locations. Hospitalists also play an integral role in ensuring the hospital performs well on quality metrics, including 30-day readmissions, hospital acquired conditions, and patient satisfaction. Examples below document the effectiveness of hospitalists in this new ACO era.

Care Transitions/Coordination

Before the Hospital Readmission Reduction Program (HRRP) delineated in the ACA, hospitalists developed Project BOOST (Better Outcomes by Optimizing Care Transitions) to improve hospital discharge care transition. The evidence-based foundation of this project led CMS to list Project BOOST as an example program that can reduce readmissions.²⁴ Through the dissemination and mentored implementation of Project BOOST to over 200 hospitals across the United States,²⁵ hospitalists contributed to the marked reduction in hospital readmission occurring since 2010.²⁶ Although hospital medicine began as a practice specific to the hospital setting, hospitalists’ skills generated growing demand for them in postacute facilities. SNF residents commonly come from hospitals postdischarge and suffer from multiple comorbidities and limitations in activities of daily living. Not surprisingly, SNF residents experience high rates of rehospitalizations.²⁷ Hospitalists can serve as a bridge between hospitals and SNFs and optimize this transition process to yield improved outcomes. Industry experts endorse this approach.²⁸ A recent study demonstrated a significant reduction in readmissions in 1 SNF (32.3% to 16.1%, odds ratio = 0.403, P < .001), by having a hospitalist-led team follow patients discharged from the hospital.²⁹

Chronic Conditions Management/High-Risk Patients

Interest in patients with multiple chronic comorbidities and social issues intensifies as healthcare systems focus limited resources on these high-risk patients to prevent the unnecessary use of costly services.^30,31 As health systems assume financial risk for health outcomes and costs of designated patient groups, they undertake efforts to understand the population they serve. Such efforts aim to identify patients with established high utilization patterns (or those at risk for high utilization). This knowledge enables targeted actions to provide access, treatment, and preventive interventions to avoid unneeded emergency and hospital services. Hospitalists commonly care for these patients and are positioned to lead the implementation of patient risk assessment and stratification, develop patient-centered care models across care settings, and act as a liaison with primary care. For frail elderly and seriously ill patients, the integration of hospitalists into palliative care provides several opportunities for improving the quality of care at the end of life.³² As patients and their family caregivers commonly do not address goals of care until faced with a life-threatening condition in the hospital, hospitalists represent ideal primary palliative care physicians to initiate these conversations.³³ A hospitalist communicating with a patient and/or their family caregiver about alleviating symptoms and clarifying patients’ preferences for care often yields decreases in ineffective healthcare utilization and better patient outcomes. The hospitalists’ ability to communicate with other providers within the hospital setting also allows them to better coordinate interdisciplinary care and prevent unnecessary and ineffective treatments and procedures.

De-Implementation/Waste Reduction

The largest inefficiencies in healthcare noted in the National Academy of Medicine report, Demanding Value from Our Health Care (2012), are failure to deliver known beneficial therapies or providing unnecessary or nonevidenced based services that do not improve outcomes, but come with associated risk and cost.³⁴ “De-implementation” of unnecessary diagnostic tests or ineffective or even harmful treatments by hospitalists represents a significant opportunity to reduce costs while maintaining or even improving the quality of care. The Society of Hospital Medicine joined the Choosing Wisely^® campaign and made 5 recommendations in adult care as an explicit starting point for eliminating waste in the hospital in 2013.³⁵ Since then, hospitalists have participated in multiple successful efforts to address overutilization of care; some published results include the following:

• decreased frequency of unnecessary common labs through a multifaceted hospitalist QI intervention;³⁶
• reduced length of stay and cost by appropriate use of telemetry;³⁷ and
• reduced unnecessary radiology testing by providing physicians with individualized audit and feedback reports.³⁸

Hundreds of ACOs now exist across the US, formed by a variety of providers including hospitals, physician groups, and integrated delivery systems. Provider groups range in size from primary care-focused physician groups with a handful of offices to large, multistate integrated delivery systems with dozens of hospitals and hundreds of office locations. Evaluations of ACO outcomes reveal mixed results.^9,39-53 Admittedly, assessments attempting to compare the magnitude of savings across ACO models are difficult given the variation in size, variability in specific efforts to influence utilization, and substantial turnover among participating beneficiaries.⁵⁴ Nonetheless, a newly published Office of Inspector General report⁵⁵ showed that most Medicare ACOs reduced spending and improved care quality (82% of the individual quality measures) over the first 3 years of the program, and savings increased with duration of an ACO program. The report also noted that considerable time and managerial resources are required to implement changes to improve quality and lower costs. While the political terrain ostensibly supports value-based care and the need to diminish the proportion of our nation’s gross domestic product dedicated to healthcare, health systems are navigating an environment that still largely rewards volume. Hospitalists may be ideal facilitators for this transitional period as they possess the clinical experience caring for complex patients with multiple comorbidities and quality improvement skills to lead efforts in this new ACO era.

We believe that hospitalists can have more influence over these cost areas by influencing treatment of hospitalized patients in a timely manner, discharge coordination, and selection of appropriate disposition locations. Hospitalists also play an integral role in ensuring the hospital performs well on quality metrics, including 30-day readmissions, hospital acquired conditions, and patient satisfaction. Examples below document the effectiveness of hospitalists in this new ACO era.

Care Transitions/Coordination

Before the Hospital Readmission Reduction Program (HRRP) delineated in the ACA, hospitalists developed Project BOOST (Better Outcomes by Optimizing Care Transitions) to improve hospital discharge care transition. The evidence-based foundation of this project led CMS to list Project BOOST as an example program that can reduce readmissions.²⁴ Through the dissemination and mentored implementation of Project BOOST to over 200 hospitals across the United States,²⁵ hospitalists contributed to the marked reduction in hospital readmission occurring since 2010.²⁶ Although hospital medicine began as a practice specific to the hospital setting, hospitalists’ skills generated growing demand for them in postacute facilities. SNF residents commonly come from hospitals postdischarge and suffer from multiple comorbidities and limitations in activities of daily living. Not surprisingly, SNF residents experience high rates of rehospitalizations.²⁷ Hospitalists can serve as a bridge between hospitals and SNFs and optimize this transition process to yield improved outcomes. Industry experts endorse this approach.²⁸ A recent study demonstrated a significant reduction in readmissions in 1 SNF (32.3% to 16.1%, odds ratio = 0.403, P < .001), by having a hospitalist-led team follow patients discharged from the hospital.²⁹

Chronic Conditions Management/High-Risk Patients

Interest in patients with multiple chronic comorbidities and social issues intensifies as healthcare systems focus limited resources on these high-risk patients to prevent the unnecessary use of costly services.^30,31 As health systems assume financial risk for health outcomes and costs of designated patient groups, they undertake efforts to understand the population they serve. Such efforts aim to identify patients with established high utilization patterns (or those at risk for high utilization). This knowledge enables targeted actions to provide access, treatment, and preventive interventions to avoid unneeded emergency and hospital services. Hospitalists commonly care for these patients and are positioned to lead the implementation of patient risk assessment and stratification, develop patient-centered care models across care settings, and act as a liaison with primary care. For frail elderly and seriously ill patients, the integration of hospitalists into palliative care provides several opportunities for improving the quality of care at the end of life.³² As patients and their family caregivers commonly do not address goals of care until faced with a life-threatening condition in the hospital, hospitalists represent ideal primary palliative care physicians to initiate these conversations.³³ A hospitalist communicating with a patient and/or their family caregiver about alleviating symptoms and clarifying patients’ preferences for care often yields decreases in ineffective healthcare utilization and better patient outcomes. The hospitalists’ ability to communicate with other providers within the hospital setting also allows them to better coordinate interdisciplinary care and prevent unnecessary and ineffective treatments and procedures.

De-Implementation/Waste Reduction

The largest inefficiencies in healthcare noted in the National Academy of Medicine report, Demanding Value from Our Health Care (2012), are failure to deliver known beneficial therapies or providing unnecessary or nonevidenced based services that do not improve outcomes, but come with associated risk and cost.³⁴ “De-implementation” of unnecessary diagnostic tests or ineffective or even harmful treatments by hospitalists represents a significant opportunity to reduce costs while maintaining or even improving the quality of care. The Society of Hospital Medicine joined the Choosing Wisely^® campaign and made 5 recommendations in adult care as an explicit starting point for eliminating waste in the hospital in 2013.³⁵ Since then, hospitalists have participated in multiple successful efforts to address overutilization of care; some published results include the following:

• decreased frequency of unnecessary common labs through a multifaceted hospitalist QI intervention;³⁶
• reduced length of stay and cost by appropriate use of telemetry;³⁷ and
• reduced unnecessary radiology testing by providing physicians with individualized audit and feedback reports.³⁸

Hundreds of ACOs now exist across the US, formed by a variety of providers including hospitals, physician groups, and integrated delivery systems. Provider groups range in size from primary care-focused physician groups with a handful of offices to large, multistate integrated delivery systems with dozens of hospitals and hundreds of office locations. Evaluations of ACO outcomes reveal mixed results.^9,39-53 Admittedly, assessments attempting to compare the magnitude of savings across ACO models are difficult given the variation in size, variability in specific efforts to influence utilization, and substantial turnover among participating beneficiaries.⁵⁴ Nonetheless, a newly published Office of Inspector General report⁵⁵ showed that most Medicare ACOs reduced spending and improved care quality (82% of the individual quality measures) over the first 3 years of the program, and savings increased with duration of an ACO program. The report also noted that considerable time and managerial resources are required to implement changes to improve quality and lower costs. While the political terrain ostensibly supports value-based care and the need to diminish the proportion of our nation’s gross domestic product dedicated to healthcare, health systems are navigating an environment that still largely rewards volume. Hospitalists may be ideal facilitators for this transitional period as they possess the clinical experience caring for complex patients with multiple comorbidities and quality improvement skills to lead efforts in this new ACO era.

The accountable care organization (ACO) concept, elucidated in 2006 as the development of partnerships between hospitals and physicians to coordinate and deliver efficient care,¹ seeks to remove existing barriers to improving value.² Some advocate this concept as a promising payment model that could successfully realign the current payment system to financially reward improvements in quality and efficiency that bend the cost curve.^3,4 Hospitalists fit well with this philosophy. As the fastest growing medical specialty in the history of American medicine, from a couple of thousand hospitalists in the mid-1990s to more than 50,000, the remarkable progression of hospitalists has ostensibly been driven partially by hospitals’ efforts to improve the value equation through enhanced efficiency in inpatient care. Importantly, hospitalists probably provide care for more than half of all hospitalized Medicare beneficiaries and increasingly patients in skilled nursing facilities (ie, SNFists).⁵ Along with primary care physicians, hospitalists thus represent an essential group of physicians needed to transform care delivery.

When the Affordable Care Act (ACA) established the Medicare Shared Savings Program (MSSP), ACOs leaped from being an intellectual concept^1,2 into a pragmatic health system strategy.^3,4 Following Medicare, various private health insurance plans and some state Medicaid programs entered into contracts with groups of healthcare providers (hospitals, physicians, or health systems) to serve as ACOs for their insured enrollees.⁶ Leavitt Partners’ ACO tracking database showed that the number of ACOs increased from 157 in March of 2012 to 782 in December of 2015.⁷

Until recently, the federal government’s commitment to having 50% of total Medicare spending via value-based payment models by 2018, coupled with endorsement from state Medicaid programs and commercial insurers, demonstrated strong support for continuation of ACOs. Unexpectedly on August 15, 2017, the Centers for Medicare & Medicaid Services (CMS) outlined a plan in its proposed rulemaking to cancel the Episode Payment Models and the Cardiac Rehabilitation incentive payment model, which were scheduled to commence on January 1, 2018. CMS also plans to scale back the mandatory Comprehensive Care for Joint Replacement (CCJR) bundled payment model from 67 selected geographic areas to 34. Although this proposed rulemaking created some equipoise in the healthcare industry regarding the future of value-based reimbursement approaches, cost containment and improved efficiency remain as major focuses of the federal government’s healthcare effort. Notably, CMS offers providers that are newly excluded from the CCJR model the opportunity to voluntarily participate in the program and is expected to increase opportunities for providers to participate in voluntary rather than large-scale mandatory episode payment model initiatives. In 2018, the agency also plans to develop new voluntary bundled payment models that will meet criteria to be considered an advanced alternative payment model for Quality Payment Program purposes.

Importantly, the value-based reimbursement movement was well underway before ACA legislation. Through ACA health reform, value-based reimbursement efforts were expanded through ACOs, bundled payments, value-based purchasing, the CMS Innovation Center and other initiatives. With health systems having an overflowing plate of activities, a wait-and-see attitude might seem reasonable at first. However, being unprepared for the inevitable shift to value-based reimbursement and reduced fee-for-service revenue places an organization at risk. A successful ACO requires system-level transformation, especially cultural and structural changes to achieve clinical integration. Being embedded in health system delivery, hospitalists can help shape a team-oriented culture and foster success in value-based payment models. This requires hospitalists to take a more active role in assessing and striking a balance between high-quality, cost-efficient care and financial risk inherent in ACO models.

The key to hospitalists fulfilling their value creation potential and becoming enablers for ACO success lies in developing a thorough understanding of the aspects of an ACO that promote efficient and effective care, while accounting for financial factors. Fundamentally, the ACO concept combines provider payment and delivery system reforms. Specifically, the definition of an ACO contains 3 factors: (1) a local healthcare organization (eg, hospital or multispecialty group of physicians) with a related set of providers that (2) can be held accountable for the cost and quality of care delivered to (3) a defined population. While the notion of accountability is not new, the locus of accountability is changed in the ACO model—emphasizing accountability at the level of actual care delivery with documentation of quality and cost outcomes. The ACO approach aims to address multiple, frequent, and recurring problems, including lack of financial incentives to improve quality and reduce cost, as well as the negative consequences of a pay-for-volume system—uncoordinated and fragmented care, overutilization of unnecessary tests and treatments, and poor patient experience all manifested as unwarranted geographic variation in practice patterns, clinical outcomes, and health spending. Participants in an ACO are rewarded financially if they can slow the growth of their patients’ healthcare costs while maintaining or improving the quality of care delivered. To succeed in this ACO world, hospitalists must assume greater prudence in the use of healthcare services while improving (or at a minimum, maintaining) patient outcomes, thus excising avoidable waste across the continuum of care.

More than half of ACOs include a hospital.⁸ However, whether hospital-led ACOs possess an advantage remains to be elucidated. Early reports indicated that physician-led ACOs saved more money.^9,10 However, others argue that hospitals¹¹ are better capitalized, have greater capacity for data sharing, and possess economies of scale that allow them to invest in more advanced technology, such as predictive modeling and/or simulation software. Such analytics can identify high-cost patients (ie, multiple comorbidities), super utilizers and populations lacking care, allowing ACOs to implement preventive measures to reduce unnecessary utilization. Recently released CMS MSSP 2016 performance data¹² showed that nearly half (45%) of physician-only ACOs earned shared savings, whereas 23% of ACOs that include hospitals earned shared savings. However, among all the ACOs that achieved savings, ACO entities that include hospitals generated the highest amount of shared savings (eg, Advocate, Hackensack Alliance, Cleveland Clinic, and AMITA Health). Notably, hospital-led ACOs tend to have much larger beneficiary populations than physician-led ACOs, which may create a scenario of higher risk but higher potential reward.

The emphasis on value over volume inherent in the development of ACOs occurs through employing care strategies implemented through changes in policies, and eventual structural and cultural changes. These changes require participating organizations to possess certain key competencies, including the following: 1) leadership that facilitates change; 2) organizational culture of teamwork; 3) collaborative relationships among providers; 4) information technology infrastructure for population management and care coordination; 5) infrastructure for monitoring, managing, and reporting quality; 6) ability to manage financial risk; 7) ability to receive and distribute payments or savings; and 8) resources for patient education and support.^2,3,13-16 Table 1 summarizes the broad range of roles that hospitalists can serve in delivering care to ACO populations.^17-19

Hospitalists’ active pursuit of nonclinical training and selection for administrative positions demonstrate their proclivity to provide these competencies. In addition to full-time clinician hospitalists, who can directly influence the delivery of high-value care to patients, hospitalists serve many other roles in hospitals and each can contribute differently based on their specialized expertise. Examples include the success of the Society of Hospital Medicine’s Leadership Academy; the acknowledged expertise of hospitalists in quality improvement (QI), informatics, teamwork, patient experience, care coordination and utilization; and advancement of hospitalists to senior leadership positions (eg, CQO, CMO, CEO). Given that nearly a third of healthcare expenditures are for hospital care,²⁰ hospitalists are in a unique position to foster ACO competencies while impacting the quality of care episodes associated with an index hospital stay.

Importantly, hospitalists cannot act as gatekeepers to restrict care. Managed care organizations and health maintenance organizations use of this approach in the 1990s to limit access to services in order to reduce costs led to unacceptable outcomes and numerous malpractice lawsuits. ACOs should aspire to deliver the most cost-effective high-quality care, and their performance should be monitored to ensure that they provide recommended services and timely access. The Medicare ACO contract holds the provider accountable for meeting 34 different quality measures (Supplemental Table 1), and hospitalists can influence outcomes for the majority. Especially through hospital and health system QI initiatives, hospitalists can directly impact and share accountability for measures ranging from care coordination to implementation of evidence-based care (eg, ACE inhibitors and beta blockers for heart failure) to patient and family caregiver experience.

Aligned with Medicare ACO quality measures, 5 high-impact target areas were identified for ACOs²¹: (1) Prevention and wellness; (2) Chronic conditions/care management; (3) Reduced hospitalizations; (4) Care transitions across the fragmented system; and (5) Multispecialty care coordination of complex patients. One essential element of a successful ACO is the ability to implement evidence-based medical guidelines and/or practices across the continuum of care for selected targeted initiatives. Optimizing care coordination/continuum requires team-based care, and hospitalists already routinely collaborate with nurses, social workers, case managers, pharmacists, and other stakeholders such as dieticians and physical therapists on inpatient care. Hospitalists are also experienced in facilitating communication and improving integration and coordination efficiencies among primary care providers and specialists, and between hospital care and post-acute care, as they coordinate post-hospital care and follow-up. This provides an opportunity to lead health system care coordination efforts, especially for complex and/or high-risk patients.^22,23 CMS MSSP 2016 performance data¹² showed that ACOs achieving shared savings had a decline in inpatient expenditures and utilization across several facility types (hospital, SNF, rehabilitation, long term). Postacute care management is critical to earning shared savings; SNF and Home Health expenditures fell by 18.3% and 9.7%, respectively, on average. We believe that hospitalists can have more influence over these cost areas by influencing treatment of hospitalized patients in a timely manner, discharge coordination, and selection of appropriate disposition locations. Hospitalists also play an integral role in ensuring the hospital performs well on quality metrics, including 30-day readmissions, hospital acquired conditions, and patient satisfaction. Examples below document the effectiveness of hospitalists in this new ACO era.

Care Transitions/Coordination

Before the Hospital Readmission Reduction Program (HRRP) delineated in the ACA, hospitalists developed Project BOOST (Better Outcomes by Optimizing Care Transitions) to improve hospital discharge care transition. The evidence-based foundation of this project led CMS to list Project BOOST as an example program that can reduce readmissions.²⁴ Through the dissemination and mentored implementation of Project BOOST to over 200 hospitals across the United States,²⁵ hospitalists contributed to the marked reduction in hospital readmission occurring since 2010.²⁶ Although hospital medicine began as a practice specific to the hospital setting, hospitalists’ skills generated growing demand for them in postacute facilities.

Industry experts endorse this approach.²⁸ A recent study demonstrated a significant reduction in readmissions in 1 SNF (32.3% to 16.1%, odds ratio = 0.403, P < .001), by having a hospitalist-led team follow patients discharged from the hospital.²⁹

CHICAGO – Median intramyocardial triglyceride content was nearly four times higher in a group of middle-age women living with HIV, compared with peers without the infection, according to a recent study that also found an association between high myocardial lipids and lower diastolic function.

Intramyocardial triglyceride content was 0.49% (95% confidence interval, 0.39-2.09) among the women with HIV. For women without HIV, the value was 0.13% (95% CI, 0.11-0.23; P = .004). Further, left atrial passive ejection fraction was significantly lower among women living with HIV, compared with those without HIV (28% vs. 38%, P = .02), said Mabel Toribio, MD, speaking at the annual meeting of the Endocrine Society.

“Probably the most important aspect is that we found an inverse relationship between the intramyocardial triglyceride content and the diastolic function; the higher the intracardiac lipid content of the women living with HIV, the worse their cardiac function,” Dr. Toribio said in an interview. She and her colleagues at Massachusetts General Hospital, Boston, where she is a clinical investigator, found a Spearman’s rank coefficient of –0.51 for the correlation (P = .03)

“The reason that this is important is that individuals with HIV do have an increased risk of heart failure,” said Dr. Toribio. People living with HIV have a hazard ratio for heart failure that ranges from about 1.2 to 1.7, she said.

For women living with HIV with heart failure, about 70% have heart failure with preserved ejection fraction (HFpEF), which is associated with diastolic dysfunction. “In women with HIV, this has been relatively understudied, and one of the mechanisms we were looking into is myocardial steatosis, where we have increased intramyocardial lipid content,” said Dr. Toribio.

“I think, certainly, our work has a lot of clinical implications,” said Dr. Toribio, noting that there are no therapies that improve survival after a diagnosis of HFpEF. In a population with increased rates of diastolic dysfunction, “It’s imperative that we understand the mechanism of this disease process in women living with HIV,” she said.

Intramyocardial lipid content was a reasonable line of inquiry, since it’s known that people living with HIV have increased deposition of fat in various organ systems, including the liver, skeletal muscle, and the heart, said Dr. Toribio. Both HIV and antiretroviral therapy can contribute to ectopic fat deposition, she said.

Magnetic resonance spectroscopy was used to assess intramyocardial triglyceride levels, measured at the interventricular septum, a region where there’s little overlying pericardial fat.

“We found that the women living with HIV have an increased intramyocardial triglyceride content compared to women without HIV. And notably, we sought to see if there was any relationship between circulating triglyceride levels or body mass index, and there actually was no relationship between intramyocardial triglyceride content and these factors,” said Dr. Toribio in a video interview.

Next steps include two studies, said Dr. Toribio. The first is investigating whether statin therapy improves myocardial steatosis and heart function over time in women living with HIV. The second, involving the same population, is a pilot study to see if growth hormone releasing hormone – which is known to lessen visceral adiposity in people living with HIV – can reduce intramyocardial steatosis and boost cardiac function, she said.

Dr. Toribio reported no financial disclosures. The study was supported by funding from the National Institutes of Health.

While patients may be newly exposed to opioids during medical and surgical hospitalization and the prescription of opioids at discharge is common,^1-5 prescribers of opioids at discharge may not intend to initiate long-term opioid (LTO) use. By understanding the frequency of progression to LTO use, hospitalists can better balance postdischarge pain treatment and the risk for unintended LTO initiation.

Estimates of LTO use rates following hospital discharge in selected populations^1,2,4-6 have varied depending on the population studied and the method of defining LTO use.⁷ Rates of LTO use following incident opioid prescription have not been directly compared at medical versus surgical discharge or compared with initiation in the ambulatory setting. We present the rates of LTO use following incident opioid exposure at surgical discharge and medical discharge and identify the factors associated with LTO use following surgical and medical discharge.

Data Sources

Veterans Health Administration (VHA) data were obtained through the Austin Information Technology Center for fiscal years (FYs) 2003 through 2012 (Austin, Texas). Decision support system national data extracts were used to identify prescription-dispensing events, and inpatient and outpatient medical SAS data sets were used to identify diagnostic codes. The study was approved by the University of Iowa Institutional Review Board and the Iowa City Veterans Affairs (VA) Health Care System Research and Development Committee.

Patients

We included all patients with an outpatient opioid prescription during FY 2011 that was preceded by a 1-year opioid-free period.⁷ Patients with broadly accepted indications for LTO use (eg, metastatic cancer, palliative care, or opioid-dependence treatment) were excluded.⁷

Opioid Exposure

We included all outpatient prescription fills for noninjectable dosage forms of butorphanol, fentanyl, hydrocodone, hydromorphone, levorphanol, meperidine, methadone, morphine, oxycodone, oxymorphone, pentazocine, and tramadol. Consistent with the Centers for Disease Control and Prevention and VA/Department of Defense guidelines, LTO use was defined conceptually as regular use for >90 days. Operationalizing this definition to pharmacy refill data was established by using a cabinet supply methodology,⁷ which allows for the construction of episodes of continuous medication therapy by estimating the medication supply available to a patient for each day during a defined period based on the pattern of observed refills. LTO use was defined as an episode of continuous opioid supply for >90 days and beginning within 30 days of the initial prescription. While some studies have defined LTO use based on onset within 1 year following surgery,⁵ the requirement for onset within 30 days of initiation was applied to more strongly tie the association of developing LTO use with the discharge event and minimize various forms of bias that are introduced with extended follow-up periods.

Clinical Characteristics

Patients were classified as being medical discharges, surgical discharges, or outpatient initiators. Patients with an opioid index date within 2 days following discharge were designated based on discharge bed section; additionally, if patients had a surgical bed section during hospitalization, they were assigned as surgical discharges. Demographic, diagnosis, and medication exposure variables that were previously associated with LTO use were selected.^8,9 Substance use disorder, chronic pain, anxiety disorder, and depressive disorder were based on International Classification of Diseases, 9th Revision (ICD-9) codes in the preceding year. The use of concurrent benzodiazepines, skeletal muscle relaxants, and antidepressants were determined at opioid initiation.¹⁰ Rural or urban residence was assigned by using the Rural-Urban Commuting Area Codes system and mapped with the zip code of a veteran’s residence.¹¹

Analysis

Bivariate and multivariable relationships were determined by using logistic regression. The multivariable model considered all pairwise interaction terms between inpatient service (surgery versus medicine) and each of the variables in the model. Statistically significant interaction terms (P < .05) were retained, and all others were omitted from the final model. The main effects for variables that were involved in a significant interaction term were not reported in the final multivariable model; instead, we created fully specified multivariable models for surgery service and medicine service and reported odds ratios (ORs) for the main effects. All analyses were conducted by using SAS version 9.4 (SAS Institute Inc, Cary, North Carolina).

The observation that subsequent LTO use occurs more frequently in discharged medical patients than surgical patients is consistent with the findings of Calcaterra et al.¹ that among patients with no surgery versus surgery during hospitalization, opioid receipt at discharge resulted in a higher adjusted OR (7.24 for no surgery versus 3.40 for surgery) for chronic opioid use at 1 year. One explanation for this finding may be an artifact of cohort selection in the study design: patients with prior opioid use are excluded from the cohort, and prior use may be more common among surgical patients presenting for elective inpatient surgery for painful conditions. Previous work suggests that opioid use preoperatively is a robust predictor of postoperative use, and rates of LTO use are low among patients without preoperative opioid exposure.⁶

Demographic characteristics associated with persistent opioid receipt were similar to those previously reported.^5,8,9 The inclusion of medication classes indicated in the treatment of mental health or pain conditions (ie, antidepressants, benzodiazepines, muscle relaxants, and nonopioid analgesics) resulted in diagnoses based on ICD-9 codes being no longer associated with LTO use. Severity or activity of illness, preferences regarding pharmacologic or nonpharmacologic treatment and undiagnosed or undocumented pain-comorbid conditions may all contribute to this finding. Future work studying opioid-related outcomes should include variables that reflect pharmacologic management of comorbid diagnoses in the cohort development or analytic design.

The strongest risk factors were potentially modifiable: days’ supply, dose, and concurrent medications. The measures of opioid quantity supplied are associated with subsequent ongoing use and are consistent with recent work based on prescription drug–monitoring data in a single state¹⁴ and in a nationally representative sample.¹⁵ That this relationship persists following hospital discharge, a scenario in which LTO use is unlikely to be initiated by a provider (who would be expected to subsequently titrate or monitor therapy), further supports the potential to curtail unintended LTO use through judicious early prescribing decisions.

We assessed only opioids that were supplied through a VA pharmacy, which may lead to the misclassification of patients as opioid naive for inclusion and an underestimation of the rate of opioid use following discharge. It is possible that differences in the rates of non-VA pharmacy use differ in medical and surgical populations in a nonrandom way. This study was performed in a large, integrated health system and may not be generalizable outside the VA system, where more discontinuities between hospital and ambulatory care may exist.

The initiation of LTO use at discharge is more common in veterans who are discharged from medical than surgical hospitalizations, likely reflecting differences in the patient population, pain conditions, and discharge prescribing decisions. While patient characteristics are associated with LTO use, the strongest associations are with increasing index dose and days’ supply; both represent potentially modifiable prescriber behaviors. These findings support policy changes and other efforts to minimize dose and days supplied when short-term use is intended as a means to address the current opioid epidemic.

While patients may be newly exposed to opioids during medical and surgical hospitalization and the prescription of opioids at discharge is common,^1-5 prescribers of opioids at discharge may not intend to initiate long-term opioid (LTO) use. By understanding the frequency of progression to LTO use, hospitalists can better balance postdischarge pain treatment and the risk for unintended LTO initiation.

Estimates of LTO use rates following hospital discharge in selected populations^1,2,4-6 have varied depending on the population studied and the method of defining LTO use.⁷ Rates of LTO use following incident opioid prescription have not been directly compared at medical versus surgical discharge or compared with initiation in the ambulatory setting. We present the rates of LTO use following incident opioid exposure at surgical discharge and medical discharge and identify the factors associated with LTO use following surgical and medical discharge.

Data Sources

Veterans Health Administration (VHA) data were obtained through the Austin Information Technology Center for fiscal years (FYs) 2003 through 2012 (Austin, Texas). Decision support system national data extracts were used to identify prescription-dispensing events, and inpatient and outpatient medical SAS data sets were used to identify diagnostic codes. The study was approved by the University of Iowa Institutional Review Board and the Iowa City Veterans Affairs (VA) Health Care System Research and Development Committee.

Patients

We included all patients with an outpatient opioid prescription during FY 2011 that was preceded by a 1-year opioid-free period.⁷ Patients with broadly accepted indications for LTO use (eg, metastatic cancer, palliative care, or opioid-dependence treatment) were excluded.⁷

Opioid Exposure

We included all outpatient prescription fills for noninjectable dosage forms of butorphanol, fentanyl, hydrocodone, hydromorphone, levorphanol, meperidine, methadone, morphine, oxycodone, oxymorphone, pentazocine, and tramadol. Consistent with the Centers for Disease Control and Prevention and VA/Department of Defense guidelines, LTO use was defined conceptually as regular use for >90 days. Operationalizing this definition to pharmacy refill data was established by using a cabinet supply methodology,⁷ which allows for the construction of episodes of continuous medication therapy by estimating the medication supply available to a patient for each day during a defined period based on the pattern of observed refills. LTO use was defined as an episode of continuous opioid supply for >90 days and beginning within 30 days of the initial prescription. While some studies have defined LTO use based on onset within 1 year following surgery,⁵ the requirement for onset within 30 days of initiation was applied to more strongly tie the association of developing LTO use with the discharge event and minimize various forms of bias that are introduced with extended follow-up periods.

Clinical Characteristics

Patients were classified as being medical discharges, surgical discharges, or outpatient initiators. Patients with an opioid index date within 2 days following discharge were designated based on discharge bed section; additionally, if patients had a surgical bed section during hospitalization, they were assigned as surgical discharges. Demographic, diagnosis, and medication exposure variables that were previously associated with LTO use were selected.^8,9 Substance use disorder, chronic pain, anxiety disorder, and depressive disorder were based on International Classification of Diseases, 9th Revision (ICD-9) codes in the preceding year. The use of concurrent benzodiazepines, skeletal muscle relaxants, and antidepressants were determined at opioid initiation.¹⁰ Rural or urban residence was assigned by using the Rural-Urban Commuting Area Codes system and mapped with the zip code of a veteran’s residence.¹¹

Analysis

Bivariate and multivariable relationships were determined by using logistic regression. The multivariable model considered all pairwise interaction terms between inpatient service (surgery versus medicine) and each of the variables in the model. Statistically significant interaction terms (P < .05) were retained, and all others were omitted from the final model. The main effects for variables that were involved in a significant interaction term were not reported in the final multivariable model; instead, we created fully specified multivariable models for surgery service and medicine service and reported odds ratios (ORs) for the main effects.

While every day seems to bring extraordinary new advances in science – robotic surgery, individually targeted medications, and even gene therapy – there are many people who currently approach the science of medicine with skepticism.

While it is the right of legally competent adults in a free society to chose how best to care for their own health, to explore holistic or alternative therapies, or avoid medicine altogether, it is more complex when they are skeptical of accepted medical practice in managing the health of their children. For those parents who trust you enough to bring their children to you for care but remain skeptical of vaccines or other treatments, you have an opportunity to work with that trust and engage in a discussion so that they might reconsider their position on valuable and even life-saving treatments for their children.

CHICAGO – Empagliflozin, an oral sodium-glucose cotransporter 2 (SGLT-2), reduced liver fat by 5% and improved ALT in patients with nonalcoholic fatty liver disease (NAFLD) and type 2 diabetes mellitus, according to a study presented at the annual meeting of the Endocrine Society.

As insulin resistance is the mechanism for NAFLD development, this new addition to the list of drugs on offer to patients with diabetes could help decrease the chance of developing metabolic syndrome and cardiovascular disease.

“SGLT-2 inhibitors are newer antidiabetic agents that reduce blood glucose by promoting urinary glucose excretion,” said presenter Mohammad Shafi Kuchay, MD, DM, an endocrinologist at Medanta The Medicity, Gurugram, India. “NAFLD, which also increases the risk of type 2 diabetes, often responds to strategies that improve hyperglycemia.”

Dr. Kuchay and fellow investigators conducted a small, 20-week randomized controlled trial of 42 patients with type 2 diabetes and NAFLD.

Patients in the test group were mostly male and on average 50 years old, with baseline AST, ALT, and gamma-glutamyltransferase scores of 44.6 U/L, 64.3 U/L, and 65.8 U/L, respectively. Those randomized to the control group had similar characteristics.

After adding 10 mg of empagliflozin to their diabetes regimen, liver fat density in test patients decreased from 16.2% to 11.3% (P less than or equal to .0001). The drop stands in sharp contrast to the control group, which decreased from 16.4% to 15.5% (P = .054). Measurement of liver fat density was made by MRI-derived proton density fat fraction (MRI-PDFF). This method has higher sensitivity for detecting changes in liver fat, compared with histology, explained Dr. Kuchay.

When broken down by individual liver fat, 25% of patients in the control group increased in liver fat, 50% had no significant change, and 25% decreased in liver fat, according to Dr. Kuchay.

The use of bolus-dose vasopressors in anesthesiology and other areas of critical care medicine is well known. This common medical intervention, however, is not often employed in emergency medicine (EM). Bolus-dose vasopressors are defined as the administration of small bolus doses of vasopressor agents, such as epinephrine or phenylephrine, to patients with compromised perfusion who continue to have a pulse (ie, these patients are not in cardiac arrest). This intervention is considered as a temporizing measure for transient hypotension or as a bridge to more definitive therapy.

Clinical Application

Bolus-dose vasopressive therapy is also referred to as push-dose pressor (PDP) therapy—a term coined by Weingart.^1-3 Theoretically, any vasopressor could be used in a mini-dose, bolus fashion, though in current clinical practice, anesthesiologists primarily employ ephedrine, epinephrine, and phenylephrine. Two of these agents are likely more appropriate for the ED, including epinephrine and phenylephrine. Both of these agents have a short half-life and therefore an abbreviated period of effect. In addition, dosing and related administration of epinephrine and phenylephrine is relatively straightforward. Moreover, most emergency physicians and nurses are quite familiar with both agents.

With respect to ephedrine, due to its longer half-life, complex dosing regimen, and associated higher-incidence of cardiovascular (CV) complications, its use is likely not appropriate in the ED as a bolus-dose vasopressor.

Epinephrine and Phenylephrine

Epinephrine is a potent sympathomimetic agent with alpha- and beta-receptor activity. In addition to its vasopressor effects, epinephrine is also an inotropic and chronotropic agent, increasing cardiac output, heart rate (HR), and systemic vascular resistance, which can markedly improve perfusion. Epinephrine also can be given to patients with hypoperfusion and/or shock due to low-cardiac output with or without vasodilation, lacking significant tachycardia.

Phenylephrine is a pure alpha agonist and therefore does not appreciably affect cardiac output and HR, but does significantly increase systemic vascular resistance and thus systemic perfusion. Phenylephrine can be used to treat patients with hypoperfusion and/or shock states due to vasodilation with coexistent, significant tachycardia.

Preparation and Administration

The preparation and dosing of push-dose epinephrine and phenylephrine are not particularly complex. Many clinicians recommend the pre-mixed, manufacturer-prepared agents for PDP therapy. These premixed formulations not only facilitate administration, but also reduce the chance of a preparation error that can result in incorrect dosing.^3-5 If pre-mixed formulations are not available, clinicians can readily prepare epinephrine and phenylephrine for PDP use.

Push-Dose Epinephrine. Clinicians can prepare epinephrine for push-dose administration as follows:^1-3

• Obtain 1 mL of epinephrine 1:10,000 (ie, 0.1 mg/mL or 100 mcg/mL);
• Obtain a 10 mL syringe of normal saline and remove 1 mL;
• Inject the 1 mL of epinephrine 1:10,000 (100 mcg/mL) into this syringe containing 9 mL of normal saline; and
• Result: 10 mL of epinephrine (10 mcg/mL), with each 1 mL of this solution containing 10 mcg of epinephrine.

Administration of push-dose epinephrine (10 mcg/mL) produces effect within 1 minute of use with a duration of approximately 5 to 10 minutes. Dosing at this concentration ranges from 0.5 to 2.0 mL every 2 to 5 minutes, delivering 5 to 20 mcg.^1-3Push-Dose Phenylephrine. To prepare phenylephrine for push-dose administration, clinicians may use the following approach:^1-3

• Obtain 1 mL of phenylephrine (10 mg/mL concentration);
• Inject this 1 mL of phenylephrine (10 mg/mL) into a 100 mL bag of normal saline; and
• Result: 100 mL of phenylephrine (100 mcg/mL), with each 1 mL of this solution containing 100 mcg of phenylephrine.

Administration of push-dose phenylephrine (100 mcg/mL) produces effect within 1 minute of use with a duration of approximately 10 to 20 minutes. Dosing at this concentration ranges from 0.5 to 2.0 mL every 2 to 5 minutes, delivering 50 to 200 mcg.^1-3Alternative Push-Dose Preparations for Phenylephrine. Two other methods of preparing phenylephrine for bolus-dose administration include the following: (1) the addition of phenylephrine 20 mg to a bag of 250 cc of normal saline, resulting in an 80 mcg/mL concentration; and/or (2) phenylephrine (20 mg) is commercially available for continuous infusion in a 250 mL bag of normal saline, yielding the same concentration of 80 mcg/mL; in either case, medication can be drawn up and administered. Dosing at this concentration ranges from 0.5 to 2.5 mL every 2 to 5 minutes, delivering 40 to 200 mcg. Lastly, phenylephrine is also commercially available in pre-made mixtures, specifically manufactured for bolus-dose therapy.

Indications

Both epinephrine and phenylephrine can be considered in the management of significant transient or sustained hypoperfusion. Although the definition of significant hypotension is complex, Brunauer et al⁶ have suggested that a mean arterial pressure (MAP) of approximately 35 mm Hg is associated with a significant risk of CV collapse. Of course, a MAP of 40 to 50 mm Hg is also very concerning clinically, with significant risk of deterioration and CV collapse.

Procedural events, such as conscious sedation or rapid sequence intubation (RSI), can produce significant hypotension; PDP can rapidly correct hypotension. In other clinical scenarios in which sustained hypotension is likely and not transient (eg, sepsis with shock), PDP can be used as a bridge to definitive care (eg, volume replacement, continuous vasopressor infusion). It is important to note, however, that PDP administration must occur in conjunction with or after the patient has received other appropriate therapies such as a normal saline bolus and continuous vasopressor infusions. Push-dose pressors are not a replacement for these proven interventions, but rather are an important augmentation to these therapies.

Emergency Medicine Literature

As previously noted, the literature base describing and supporting the clinical use of PDP in EM is extremely limited. The few articles that comprise this literature base address significant hypotension in periendotracheal intubation intervention, post-return of spontaneous circulation (ROSC) management, and shock management with preload augmentation.^7-9In addition, there are several articles in the literature that address safety concerns surrounding the use of PDP in the ED.^4,5

Panchal et al¹⁰ investigated the use of phenylephrine in hypotensive patients undergoing RSI-assisted endotracheal intubation. The authors performed a 1-year retrospective review of hypotensive patients managed with endotracheal intubation for a range of clinical conditions that required clinical care intervention. In this study, 20 of the 119 patients received phenylephrine in the peri-intubation period. A range of clinical conditions requiring critical care intervention were encountered; in addition, almost three-quarters of these patients were receiving at least one other vasopressor infusion. Further differences were seen in the timing of PDP administration. In those patients receiving bolus-dose phenylephrine, blood pressure (BP) improved without change in HR. Panchal et al¹⁰ concluded that while push-dose phenylephrine improved hemodynamic status, there was significant variation among clinicians regarding dosing, timing of use, and overall clinical situation The significant variation in PDP management in this study was noted to be a potential source of medical error, thus increasing the chance of adverse clinical event.

Push-dose pressor therapy can be employed for significant hypotension while more definitive therapy is being readied and applied. For instance, patients with significant hypotension requiring continuous vasopressor infusion can be managed with PDP while appropriate venous access is established, intravenous fluids are administered, and medications are prepared. The immediate period after resuscitation from cardiac arrest can be complicated by shock of many types. In fact, hypotension following ROSC in the cardiac arrest patient is not uncommon and has been identified as a risk issue associated with poor outcome. Prompt treatment of this altered perfusion may improve outcome. Gottlieb⁸ described three patients with ROSC after cardiac arrest. All three patients experienced significant, sustained hypotension with systolic blood pressure reading in the 50 to 60 mm Hg range; bolus-dose epinephrine was administered with significant improvement in the hemodynamic status while central venous access was established.

In a related clinical scenario, Schwartz et al⁹ considered the impact of PDP on central venous line (CVL) placement with continuous vasopressor infusion. In this ED study, although patients experienced an increase in BP, this impact was transient with approximately half of these individuals ultimately requiring CVL. In addition, serious adverse effect was noted more commonly in the phenylephrine-treated patients with “reactive” hypertension and ventricular tachycardia occurring in study patients.

Patient-Safety Considerations

In addition to the limited literature base supporting PDP use in the ED, another major significant issue focuses on safety concerns and adverse effects. Extremely limited data is available describing adverse events related to ED-administered PDP. Extrapolating from other EM and critical care administrations of peripheral epinephrine, both local and systemic adverse effects have been reported.^11,12 The range of adverse events noted in these studies are considerable, including local skin and soft-tissue injury (necrosis), end-organ tissue ischemia (eg, digits, tip of nose), acute hypertension, cardiac ischemic events, and left ventricular (LV) dysfunction.^11,12

When comparing peripheral infusion with central infusion, the risk of extravasation with resultant local tissue injury is markedly greater with peripheral vasopressor administration. In a systematic review of this issue, Loubani and Green¹¹ noted that such local adverse events were much more commonly associated with peripheral administration.

In another report of vasopressor use in the ED, Kanwar et al¹² described apparent confusion with epinephrine dosing and route of administration, resulting in very significant, systemic CV maladies, including severe elevations in BP, acute LV dysfunction, and chest pain associated with ST segment elevation.

It must be stressed that the publications by Loubani and Green¹¹ and Kanwar et al¹² described peripheral vasopressor administration: neither study included PDP therapy. Therefore, as previously noted, the aforementioned statements are extrapolated from when applied to PDP strategy.

Acquisto et al⁴ describe several errors in medication administration of PDP in the ED and other critical care areas of the hospital. In this report, all treating physicians were present at the patients’ bedside, either administering the medication or directly supervising its use. Agents involved included epinephrine and phenylephrine, delivered at exceedingly high doses. In their study, the authors noted several issues which they believe contributed to medication errors, including heterogeneity of pathology treated in these patients, apparent “earlier-than-appropriate” use of vasopressors (ie, prior to giving an appropriate fluid bolus), and medication preparation at the bedside by clinicians who may not possess the experience and training to mix these agents.

From a patient-safety perspective, Holden et al⁵ noted the potential for dosing error with significant adverse medical consequence related to PDP, as well as several contributing issues. First, they highlight the lack of a solid literature base to support administration of PDP in the ED and the development of decision-making guidelines for use in the ED. They also observed an inconsistency in approach to patient selection, medication choice, agent preparation, dosing, and other therapies. As seen in the Acquisto et al⁴ report, the patient-care scenarios are high risk and quite dynamic.

Conclusion

Bolus-dose vasopressor therapy is a potentially very useful treatment in the ED and other emergency/critical care settings. However, despite its benefits in treating patients in shock or with hypoperfusion, PDP is not widely used in EM due to the lack of studies, reviews, and guidelines in the literature to support its use in the ED. Such a literature base is required to provide an appropriate, safe means of patient selection, medication choice, dosing, and administration. Continued educational and research efforts are needed to more fully explore the use of PDP therapy in the ED.

When used correctly and appropriately, PDP has promise to be an important aid in the management of shock in the ED. Although bolus-dose therapy is appropriate for select clinical scenarios involving significant shock states which have the potential for progression to complete CV collapse without timely therapy, it is an adjunct to, not a replacement for commonly employed and medically indicated therapies such as crystalloid bolus or continuous vasopressor infusions.

The use of bolus-dose vasopressors in anesthesiology and other areas of critical care medicine is well known. This common medical intervention, however, is not often employed in emergency medicine (EM). Bolus-dose vasopressors are defined as the administration of small bolus doses of vasopressor agents, such as epinephrine or phenylephrine, to patients with compromised perfusion who continue to have a pulse (ie, these patients are not in cardiac arrest). This intervention is considered as a temporizing measure for transient hypotension or as a bridge to more definitive therapy.

Clinical Application

Bolus-dose vasopressive therapy is also referred to as push-dose pressor (PDP) therapy—a term coined by Weingart.^1-3 Theoretically, any vasopressor could be used in a mini-dose, bolus fashion, though in current clinical practice, anesthesiologists primarily employ ephedrine, epinephrine, and phenylephrine. Two of these agents are likely more appropriate for the ED, including epinephrine and phenylephrine. Both of these agents have a short half-life and therefore an abbreviated period of effect. In addition, dosing and related administration of epinephrine and phenylephrine is relatively straightforward. Moreover, most emergency physicians and nurses are quite familiar with both agents.

With respect to ephedrine, due to its longer half-life, complex dosing regimen, and associated higher-incidence of cardiovascular (CV) complications, its use is likely not appropriate in the ED as a bolus-dose vasopressor.

Epinephrine and Phenylephrine

Epinephrine is a potent sympathomimetic agent with alpha- and beta-receptor activity. In addition to its vasopressor effects, epinephrine is also an inotropic and chronotropic agent, increasing cardiac output, heart rate (HR), and systemic vascular resistance, which can markedly improve perfusion. Epinephrine also can be given to patients with hypoperfusion and/or shock due to low-cardiac output with or without vasodilation, lacking significant tachycardia.

Phenylephrine is a pure alpha agonist and therefore does not appreciably affect cardiac output and HR, but does significantly increase systemic vascular resistance and thus systemic perfusion. Phenylephrine can be used to treat patients with hypoperfusion and/or shock states due to vasodilation with coexistent, significant tachycardia.

Preparation and Administration

The preparation and dosing of push-dose epinephrine and phenylephrine are not particularly complex. Many clinicians recommend the pre-mixed, manufacturer-prepared agents for PDP therapy. These premixed formulations not only facilitate administration, but also reduce the chance of a preparation error that can result in incorrect dosing.^3-5 If pre-mixed formulations are not available, clinicians can readily prepare epinephrine and phenylephrine for PDP use.

Push-Dose Epinephrine. Clinicians can prepare epinephrine for push-dose administration as follows:^1-3

• Obtain 1 mL of epinephrine 1:10,000 (ie, 0.1 mg/mL or 100 mcg/mL);
• Obtain a 10 mL syringe of normal saline and remove 1 mL;
• Inject the 1 mL of epinephrine 1:10,000 (100 mcg/mL) into this syringe containing 9 mL of normal saline; and
• Result: 10 mL of epinephrine (10 mcg/mL), with each 1 mL of this solution containing 10 mcg of epinephrine.

Administration of push-dose epinephrine (10 mcg/mL) produces effect within 1 minute of use with a duration of approximately 5 to 10 minutes. Dosing at this concentration ranges from 0.5 to 2.0 mL every 2 to 5 minutes, delivering 5 to 20 mcg.^1-3Push-Dose Phenylephrine. To prepare phenylephrine for push-dose administration, clinicians may use the following approach:^1-3

• Obtain 1 mL of phenylephrine (10 mg/mL concentration);
• Inject this 1 mL of phenylephrine (10 mg/mL) into a 100 mL bag of normal saline; and
• Result: 100 mL of phenylephrine (100 mcg/mL), with each 1 mL of this solution containing 100 mcg of phenylephrine.

Administration of push-dose phenylephrine (100 mcg/mL) produces effect within 1 minute of use with a duration of approximately 10 to 20 minutes. Dosing at this concentration ranges from 0.5 to 2.0 mL every 2 to 5 minutes, delivering 50 to 200 mcg.^1-3Alternative Push-Dose Preparations for Phenylephrine. Two other methods of preparing phenylephrine for bolus-dose administration include the following: (1) the addition of phenylephrine 20 mg to a bag of 250 cc of normal saline, resulting in an 80 mcg/mL concentration; and/or (2) phenylephrine (20 mg) is commercially available for continuous infusion in a 250 mL bag of normal saline, yielding the same concentration of 80 mcg/mL; in either case, medication can be drawn up and administered. Dosing at this concentration ranges from 0.5 to 2.5 mL every 2 to 5 minutes, delivering 40 to 200 mcg. Lastly, phenylephrine is also commercially available in pre-made mixtures, specifically manufactured for bolus-dose therapy.

Indications

Both epinephrine and phenylephrine can be considered in the management of significant transient or sustained hypoperfusion. Although the definition of significant hypotension is complex, Brunauer et al⁶ have suggested that a mean arterial pressure (MAP) of approximately 35 mm Hg is associated with a significant risk of CV collapse. Of course, a MAP of 40 to 50 mm Hg is also very concerning clinically, with significant risk of deterioration and CV collapse.

Procedural events, such as conscious sedation or rapid sequence intubation (RSI), can produce significant hypotension; PDP can rapidly correct hypotension. In other clinical scenarios in which sustained hypotension is likely and not transient (eg, sepsis with shock), PDP can be used as a bridge to definitive care (eg, volume replacement, continuous vasopressor infusion). It is important to note, however, that PDP administration must occur in conjunction with or after the patient has received other appropriate therapies such as a normal saline bolus and continuous vasopressor infusions.

The likelihood that a trauma or acute care surgeon will encounter or treat a transgender patient in an emergency setting is increasing every year.

The number of patients who self-identify as transgender and who have undergone both medical and/or surgical gender-affirming treatment is on the rise. The trend has accelerated since private insurers, Medicare, and Medicaid are now covering some of the costs (JAMA Surg. 2018 Feb 28. doi: 10.1001/jamasurg.2017.6231).

Privacy concerns can be of particular sensitivity. “Care must be taken to maintain privacy for the patient, as others outside of the hospital may not know they are transgender. Consultation with the patient’s primary care provider may be beneficial to determine the extent of gender-affirmation and the patient’s disclosure to family and friends,” the investigator advised. In addition, the clinician needs to establish which if any nonmedical interventions the transgender patients has had. These may include nonprescription hormone therapy and silicone injections.

The encounter should include an evaluation for injury to genitalia. “Transgender patients may have significant dysphoria associated with their preoperative genitals,” Dr. Mandell and his coauthors said. In these cases, “involvement of providers experienced with examination of transgender patients should be sought, if possible.” These patients should be screened for potential abuse by a companion or self-injury, the investigators suggested.

Dr. Mandell and his coauthors also discussed some of the nuances of trauma care for this population. For example, transgender women may need a smaller endotracheal tube for establishing an airway as intubation to avoid damaging surgically altered vocal chords. Other craniofacial alterations can get in the way of establishing an airway. Clinicians also should keep in mind the increased likelihood of a venous thromboembolism from estrogen hormone therapy in immobilized transgender patients in the trauma setting. Implants and surgical alterations can add a layer of complexity to reading images. Anatomical rearrangement can make catheterization challenging.

Dr. Mandell and his coauthors concluded, “Further research is needed on the appropriate management of cross-gender hormones, dosing of medications and nutrition, and the special considerations for injury patterns and risks in transgender patients. Development of a system for quickly determining the state of gender-affirmation of the patient in regards to hormone therapy, surgeries, and social aspects may prove beneficial to providers in the setting of trauma, but involvement of the transgender population in the development of any such system is crucial.”

Eileen M. Bulger, MD, FACS, Chair ACS Committee on Trauma and one of the coauthors of the study, views the findings as potentially useful to meet the training deficit on transgender trauma issues. “As trauma surgeons, we strive to provide optimal care by attending to the physical, psychological, and social needs of our patients. This review raises awareness of critical issues to consider when caring for transgender patients and should be included in our educational programs for trauma fellowship training and used as a resource to raise awareness in our trauma centers.”

Dr. Mandell and his coauthors reported having no financial disclosures.

The encounter should include an evaluation for injury to genitalia. “Transgender patients may have significant dysphoria associated with their preoperative genitals,” Dr. Mandell and his coauthors said. In these cases, “involvement of providers experienced with examination of transgender patients should be sought, if possible.” These patients should be screened for potential abuse by a companion or self-injury, the investigators suggested.

Dr. Mandell and his coauthors also discussed some of the nuances of trauma care for this population. For example, transgender women may need a smaller endotracheal tube for establishing an airway as intubation to avoid damaging surgically altered vocal chords. Other craniofacial alterations can get in the way of establishing an airway. Clinicians also should keep in mind the increased likelihood of a venous thromboembolism from estrogen hormone therapy in immobilized transgender patients in the trauma setting. Implants and surgical alterations can add a layer of complexity to reading images. Anatomical rearrangement can make catheterization challenging.

Dr. Mandell and his coauthors concluded, “Further research is needed on the appropriate management of cross-gender hormones, dosing of medications and nutrition, and the special considerations for injury patterns and risks in transgender patients. Development of a system for quickly determining the state of gender-affirmation of the patient in regards to hormone therapy, surgeries, and social aspects may prove beneficial to providers in the setting of trauma, but involvement of the transgender population in the development of any such system is crucial.”

Eileen M. Bulger, MD, FACS, Chair ACS Committee on Trauma and one of the coauthors of the study, views the findings as potentially useful to meet the training deficit on transgender trauma issues. “As trauma surgeons, we strive to provide optimal care by attending to the physical, psychological, and social needs of our patients. This review raises awareness of critical issues to consider when caring for transgender patients and should be included in our educational programs for trauma fellowship training and used as a resource to raise awareness in our trauma centers.”

The likelihood that a trauma or acute care surgeon will encounter or treat a transgender patient in an emergency setting is increasing every year.

The number of patients who self-identify as transgender and who have undergone both medical and/or surgical gender-affirming treatment is on the rise. The trend has accelerated since private insurers, Medicare, and Medicaid are now covering some of the costs (JAMA Surg. 2018 Feb 28. doi: 10.1001/jamasurg.2017.6231).

Privacy concerns can be of particular sensitivity. “Care must be taken to maintain privacy for the patient, as others outside of the hospital may not know they are transgender. Consultation with the patient’s primary care provider may be beneficial to determine the extent of gender-affirmation and the patient’s disclosure to family and friends,” the investigator advised. In addition, the clinician needs to establish which if any nonmedical interventions the transgender patients has had. These may include nonprescription hormone therapy and silicone injections.

CHICAGO – Women who have treatment for breast cancer seldom talk about the costs of care with their medical team, but a study out of Duke University has found that more than one-third reported having a financial burden from their breast cancer treatment, even among women with health insurance, according to a report presented at the Society of Surgical Oncology Annual Cancer Symposium.

“The financial harm associated with cancer treatment is now known as ‘financial toxicity,’ ” Rachel A. Greenup, MD, MPH, said in reporting the results of an 88-item survey completed by 654 adult women who had treatment for breast cancer. The women were recruited through the Army of Women of the Dr. Susan Love Research Foundation and The Sister’s Network of North Carolina, an African-American breast cancer survivors’ organization.

Overall, 69% of survey respondents had private insurance and 26% had Medicare. Of the patients surveyed, 94% had breast cancer surgery: 40.6% lumpectomy, 23.7% mastectomy, and 29.7% bilateral mastectomy; 34% also had breast reconstruction. Among those surveyed, 43% reported considering costs in their treatment decision. Of these, 29% considered costs when making surgical treatment decisions, including 14% who reported that costs were “extremely” important.

Despite the high levels of insurance coverage, 35% of the study participants reported a financial burden resulting from cancer treatment, ranging from “somewhat” burdensome to “catastrophic.” The median out-of-pocket cost for the study participants was $4,000, and 5% exceeded $40,000 in such costs, Dr. Greenup said. “The risk of financial harm and increased out-of-pocket costs to patients differed by surgery type,” with higher financial burdens seen in women who underwent bilateral mastectomy.

Cost was one of many factors survey participants reported considering when making surgical treatment decisions, but the most important factors were the opinions and advice of the medical team and the individual patient’s fear of recurrence. However, in lower-income women, cost factored more significantly in decision making. “In a subset of women who reported an annual income of $45,000 a year or less, cost of treatment gained importance and, interestingly, became more important than many variables we routinely discuss – for example, appearance of the breast, sexuality, avoiding radiation, and breast preservation,” Dr. Greenup said. “An income of $74,000 a year was the tipping point at which women reported incorporating costs into their cancer treatment decisions.”

She added that younger, minority women who did not have Medicare coverage were more likely to consider costs in breast cancer treatment decisions.

Most women surveyed (79%) said they preferred to know their out-of-pocket costs before they begin treatment, Dr. Greenup said, “and 40% believed that we as physicians should be considering out-of-pocket costs while making medical decisions.” However, 78% of those surveyed said they never discussed costs with their cancer team – despite American Society of Clinical Oncologists guidelines, she pointed out – and 35% said their treatment costs were higher than expected.

Dr. Greenup described the study population as “well engaged … with good insurance and strong educational background that likely does not reflect the general population.” The results may not be generalizable. “We expect that in a general cohort of women, our findings would be even more exaggerated,” she said.

The study points out the need to better understand how cost transparency may affect breast cancer treatment decisions, Dr. Greenup said. “As eligible women with breast cancer choose between surgical options, it’s important that we consider the potential risk of financial harm as we guide them through these difficult treatment decisions,” she said.

SILVER SPRING, MD.  – Members of the Food and Drug Administration Psychopharmacologic Drugs Advisory Committee voted 11 to 1 to recommend approval of lofexidine as the first nonopioid treatment option for the symptomatic treatment of opioid withdrawal.

Opioid withdrawal symptoms are the largest barrier to discontinuing opioid use, according to Louis Baxter, MD, executive medical director of the Professional Assistance Program in Princeton, N.J., who presented on behalf of U.S. WorldMeds, which plans to market lofexidine as Lucemyra.

Lofexidine, a selective alpha2-adrenergic receptor agonist that regulates norepinephrine release has been approved for management of opioid withdrawal in the United Kingdom since 1992.

The advisory committee voted to recommend lofexidine on the strength of the results of two randomized, double-blind, and placebo controlled phase 3 studies on the safety and efficacy of lofexidine for symptomatic treatment of opioid withdrawal between days 1 through 7. One study randomized 264 patients to lofexidine (134) or placebo (130), with patients in the treatment arm received 3.2 mg of lofexidine on days 1-5, then placebo until day 7. The second study randomized 603 patients to three groups, comparing high dose (3.2 mg/day) and low dose (2.4 mg/day) regimens of lofexidine to placebo; patients in the treatment arms took four smaller doses of lofexidine throughout the day to achieve the cumulative dose.

Researchers enrolled heavy users of short-acting opioids; heroin was the predominant agent. Both studies were conducted in the scenario of abrupt withdrawal, or the most intense withdrawal situation.

Symptomatic benefit was measured using the Short Opiate Withdrawal Scale of Gossop (SOWS-Gossop), a patient reported outcome. Patients were asked to rank their symptoms as none, mild, moderate or severe across measures like feeling sick, stomach cramps, and heart pounding among other symptoms.  

Lofexidine increased completion of withdrawal treatment compared to placebo. Patients in the first study had a 5-day completion rate of 53%, compared to 35% for the placebo group. Researchers observed similar results in the 7-day completion rates the second study, with low and high dose completion rates of 42% and 40%, respectively, both of which were much higher than placebo (28%).

Lofexidine also reduced patient withdrawal symptoms, according to SOWS-Gossop scores during peak withdrawal. In the first study, SOWS-Gossop scores were 2-4 points lower in the lofexidine group compared to placebo. Similarly, the scores were significantly better in both lofexidine groups in the second study, compared to placebo, particularly on days 1 to 4. Decreasing withdrawal symptoms during this period is particularly important because this is the most vulnerable window for patient dropout, briefing documents from US WorldMeds.

Several notable adverse events occurred during the study, particularly at higher doses of lofexidine. The risk of bradycardia and hypotension are prominent in patients taking lofexidine, but these are risks associated with this class of drug, according to Mark Pirner, MD, senior medical director at US WorldMeds, who noted that “the lower dose, if that’s what ultimately gets approved [by the FDA], is safe and effective too.”

Development of lofexidine was conducted in collaboration with the National Institute on Drug Abuse and the FDA, according to briefing documents from US WorldMeds.

The Prescription Drug User Fee Act (PDUFA) for lofexidine is May 26; FDA actions on new drug applications often occur at near the PDUFA date.

The FDA is not obligated to follow the recommendations of its advisory committees.
