One of the greatest tragedies of the first wave of the COVID-19 pandemic has been the failure of health policy makers to anticipate and mitigate the enormous havoc the policy of social distancing would wreak on mental health and cognitive function in older persons, speakers agreed at a webinar on COVID-19, social distancing, and its impact on social and mental health in the elderly hosted by the International Psychogeriatric Association in collaboration with INTERDEM.

“Social distancing” is a two-edged sword: It is for now and the foreseeable future the only available effective strategy for protecting against infection in the older population most vulnerable to severe forms of COVID-19. Yet social distancing also has caused many elderly – particularly those in nursing homes and other long-term care facilities – to plunge into a profound experience of loneliness, isolation, distress, feelings of abandonment, anxiety, depression, and accelerated cognitive deterioration. And this needn’t have happened, the mental health professionals asserted.

“When are we going to get rid of the term ‘social distancing?’ ” asked IPA President William E. Reichman, MD. “Many have appreciated – including the World Health Organization – that the real issue is physical distancing to prevent contagion. And physical distancing doesn’t have to mean social distancing.”

Social connectedness between elderly persons and their peers and family members can be maintained and should be emphatically encouraged during the physical distancing required by the pandemic, said Myrra Vernooij-Dassen, PhD, of Radboud University in Nigmegen, the Netherlands, and chair of INTERDEM, a pan-European network of dementia researchers.

This can be achieved using readily available technologies, including the telephone and videoconferencing, as well as by creating opportunities for supervised masked visits between a family member and an elderly loved one in outdoor courtyards or gardens within long-term care facilities. And yet, as the pandemic seized hold in many parts of the world, family members were blocked from entry to these facilities, she observed.
 

Impact on mental health, cognition

Dr. Vernooij-Dassen noted that studies of previous quarantine periods as well as preliminary findings during the COVID-19 pandemic demonstrate an inverse relationship between social isolation measures and cognitive functioning in the elderly.

“A striking finding is that lack of social interaction is associated with incident dementia. Conversely, epidemiologic data indicate that a socially integrated lifestyle had a favorable influence on cognitive functioning and could even delay onset of dementia,” she said.

INTERDEM is backing two ongoing studies evaluating the hypothesis that interventions fostering increased social interaction among elderly individuals can delay onset of dementia or favorably affect its course. The proposed mechanism of benefit is stimulation of brain plasticity to enhance cognitive reserve.

“This is a hypothesis of hope. We know that social interaction for humans is like water to plants – we really, really need it,” she explained.

Diego de Leo, MD, PhD, emeritus professor of psychiatry and former director of the Australian Institute for Suicide Research and Prevention at Griffith University in Brisbane, was living in hard-hit Padua, Italy, during the first surge of COVID-19. He described his anecdotal experience.

“What I hear from many Italian colleagues and friends and directors of mental health services is that emergency admissions related to mental disorders declined during the first wave of the COVID pandemic. For example, not many people attended emergency departments due to suicide attempts; there was a very marked decrease in the number of suicide attempts during the worst days of the pandemic,” he said.

People with psychiatric conditions were afraid to go to the hospital because they thought they would contract the infection and die there. That’s changing now, however.

“Now there is an increased number of admissions to mental health units. A new wave. It has been a U-shaped curve. And we’re now witnessing an increasing number of fatal suicides due to persistent fears, due to people imagining that there is no more room for them, and no more future for them from a financial point of view – which is the major negative outcome of this crisis. It will be a disaster for many families,” the psychiatrist continued.

A noteworthy phenomenon in northern Italy was that, when tablets were made available to nursing home residents in an effort to enhance their connectedness to the outside world, those with dementia often became so frustrated and confused by their difficulty in using the devices that they developed a hypokinetic delirium marked by refusal to eat or leave their bed, he reported.

It’s far too early to have reliable data on suicide trends in response to the pandemic, according to Dr. de Leo. But one thing is for sure: The strategy of social distancing employed to curb COVID-19 has increased the prevalence of known risk factors for suicide in older individuals, including loneliness, anxiety, and depression; increased alcohol use; and a perception of being a burden on society. Dr. de Leo directs a foundation dedicated to helping people experiencing traumatic bereavement, and in one recent week, the foundation was contacted by eight families in the province of Padua with a recent death by suicide apparently related to fallout from the COVID-19 pandemic. That’s an unusually high spike in suicide in a province with a population of 1 million.

“People probably preferred to end the agitation, the fear, the extreme anxiety about their destiny by deciding to prematurely truncate their life. That has been reported by nursing staff,” he said.

The Italian government has determined that, to date, 36% of all COVID-related deaths have occurred in people aged 85 years or older, and 84% of deaths were in individuals aged at least 70 years. And in Milan and the surrounding province of Lombardy, it’s estimated that COVID-19 has taken the lives of 25% of all nursing home residents. The North American experience has been uncomfortably similar.

“Almost 80% of COVID deaths in Canada have occurred in congregate settings,” observed Dr. Reichman, professor of psychiatry at the University of Toronto, and president and CEO of Baycrest Health Sciences, a geriatric research center.

“Certainly, the appalling number of deaths in nursing homes is the No. 1 horror of the pandemic,” declared Carmelle Peisah, MBBS, MD, a psychiatrist at the University of New South Wales in Kensington, Australia.
 

The fire next time

The conventional wisdom holds that COVID-19 has caused all sorts of mayhem in the delivery of elder care. Not so, in Dr. Reichman’s view.

“I would suggest that the pandemic has not caused many of the problems we talk about, it’s actually revealed problems that have always been there under the surface. For example, many older people, even before COVID-19, were socially isolated, socially distant. They had difficulty connecting with their relatives, difficulty accessing transportation to get to the store to buy food and see their doctors, and to interact with other older people,” the psychiatrist said.

“I would say as well that the pandemic didn’t cause the problems we’ve seen in long-term congregate senior care. The pandemic revealed them. We’ve had facilities where older people were severely crowded together, which compromises their quality of life, even when there’s not a pandemic. We’ve had difficulty staffing these kinds of environments with people that are paid an honest wage for the very hard work that they do. In many of these settings they’re inadequately trained, not only in infection prevention and control but in all other aspects of care. And the pandemic has revealed that many of these organizations are not properly funded. The government doesn’t support them well enough across jurisdictions, and they can’t raise enough philanthropic funds to provide the kind of quality of life that residents demand,” Dr. Reichman continued.

Could the pandemic spur improved elder care? His hope is that health care professionals, politicians, and society at large will learn from the devastation left by the first surge of the pandemic and will lobby for the resources necessary for much-needed improvements in geriatric care.

“We need to be better prepared should there be not only a second wave of this pandemic, but for other pandemics to come,” Dr. Reichman concluded.

The speakers indicated they had no financial conflicts regarding their presentations.

Social isolation is associated with an increased risk of a cardiovascular event of more than 40%, and of all-cause mortality approaching 50%, new research suggests. “These results are especially important in the current times of social isolation during the coronavirus crisis,” Janine Gronewold, PhD, University Hospital in Essen, Germany, told a press briefing.

The mechanism by which social isolation may boost risk for stroke, MI, or death is not clear, but other research has shown that loneliness or lack of contact with close friends and family can affect physical health, said Dr. Gronewold.

The findings were presented at the sixth Congress of the European Academy of Neurology (EAN) 2020, which transitioned to a virtual/online meeting because of the COVID-19 pandemic.

For this new study, researchers analyzed data from 4,139 participants, ranging in age from 45 to 75 years (mean 59.1 years), who were recruited into the large community-based Heinz Nixdorf Recall study. The randomly selected study group was representative of an industrial rural area of Germany, said Dr. Gronewold.

Study participants entered the study with no known cardiovascular disease and were followed for a mean of 13.4 years.
 

Social supports

Investigators collected information on three types of social support: instrumental (getting help with everyday activities such as buying food), emotional (provided with comfort), and financial (receiving monetary assistance when needed). They also looked at social integration (or social isolation) using an index with scores for marital status, number of contacts with family and friends, and membership in political, religious, community, sports, or professional associations.

Of the total, 501 participants reported a lack of instrumental support, 659 a lack of emotional support, and 907 a lack of financial support. A total of 309 lacked social integration, defined by the lowest level on the social integration index.

Participants were asked annually about new cardiovascular events, including stroke and MI. Over the follow-up period, there were 339 such events and 530 deaths.

After adjustment for age, sex, and social support, the analysis showed that social isolation was significantly associated with an increased risk of cardiovascular events (hazard ratio, 1.44; 95% confidence interval, 0.97-2.14) and all-cause mortality (HR, 1.47; 95% CI, 1.09-1.97).

The new research also showed that lack of financial support was significantly associated with increased risk for a cardiovascular event (HR, 1.30; 95% CI, 1.01-1.67).
 

Direct effect

Additional models that also adjusted for cardiovascular risk factors, health behaviors, depression, and socioeconomic factors, did not significantly change effect estimates.

“Social relationships protect us from cardiovascular events and mortality, not only via good mood, healthy behavior, and lower cardiovascular risk profile,” Dr. Gronewold said. “They seem to have a direct effect on these outcomes.”

Having strong social relationships is as important to cardiovascular health as classic protective factors such as controlling blood pressure and cholesterol levels, and maintaining a normal weight, said Dr. Gronewold.

The new results are worrying and are particularly important during the current COVID-19 pandemic, as social contact has been restricted in many areas, said Dr. Gronewold.

It is not yet clear why people who are socially isolated have such poor health outcomes, she added.

Dr. Gronewold has reported no relevant financial relationships.

Abstract

Background: Orange County’s residents have difficulty accessing timely, quality, affordable specialty care services. As the county’s only academic health system, the University of California, Irvine (UCI) aimed to improve specialty care access for the communities it serves by implementing an electronic consultations (eConsults) program that allows primary care providers (PCPs) to efficiently receive specialist recommendations on referral problems that do not require an in-person evaluation.

Objective: To implement an eConsults program at the UCI that enhances access to and the delivery of coordinated specialty care for lower-complexity referral problems.

Methods: We developed custom solutions to integrate eConsults into UCI’s 2 electronic health record platforms. The impact of the eConsults program was assessed by continuously evaluating usage and outcomes. Measures used to track usage included the number of submitted eConsult requests per PCP, the number of completed responses per specialty, and the response time for eConsult requests. Outcome measures included the specialist recommendation (eg, in-office visit, consultation avoided) and physician feedback.

Results: Over 4.5 years, more than 1400 successful eConsults have been completed, and the program has expanded to 17 specialties. The average turnaround time for an eConsult response across all specialties was 1 business day. Moreover, more than 50% of the eConsults received specialty responses within the same day of the eConsult request. Most important, about 80% of eConsult requests were addressed without the need for an in-office visit with a specialist.

Conclusion: The enhanced access to and the delivery of coordinated specialty care provided by eConsults resulted in improved efficiency and specialty access, while likely reducing costs and improving patient satisfaction. The improved communication and collaboration among providers with eConsults has also led to overwhelmingly positive feedback from both PCPs and specialists.

Orange County’s growing, aging, and diverse population is driving an increased demand for health care.¹ But with the county’s high cost of living and worsening shortage of physicians,^1-3 many of its residents are struggling to access timely, quality, affordable care. Access to specialty care services is especially frustrating for many patients and their providers, both primary care providers (PCPs) and specialists, due to problems with the referral process. Many patients experience increased wait times for a visit with a specialist due to poor communication between providers, insufficient guidance on the information or diagnostic results needed by specialists, and lack of care coordination.^4-6 One promising approach to overcome these challenges is the use of an electronic consultation, or eConsult, in place of a standard in-person referral. An eConsult is an asynchronous, non-face-to-face, provider-to-provider exchange using a secure electronic communication platform. For appropriate referral problems, the patient is able to receive timely access to specialist expertise through electronic referral by their PCP,^7-9 and avoid the time and costs associated with a visit to the specialist,^10,11 such as travel, missed work, co-pays, and child-care expenses. Clinical questions addressed using an eConsult system subsequently free up office visit appointment slots, improving access for patients requiring in-office evaluation.^8,12

Orange County’s only academic health system, the University of California, Irvine (UCI), serves a population of 3.5 million, and its principal priority is providing the communities in the county (which is the sixth largest in United States) and the surrounding region with the highest quality health care possible. Thus, UCI aimed to improve its referral processes and provide timely access to specialty care for its patients by implementing an eConsults program that allows PCPs to efficiently receive specialist recommendations on referral problems that do not require the specialist to evaluate the patient in person. This report describes our experiences with developing and implementing a custom-built eConsults workflow in UCI’s prior electronic health record (EHR) platform, Allscripts, and subsequently transitioning our mature eConsults program to a new EHR system when UCI adopted Epic. UCI is likely the only academic medical center to have experience in successfully implementing eConsults into 2 different EHR systems.

Setting

UCI’s medical center is a 417-bed acute care hospital providing tertiary and quaternary care, ambulatory and specialty medical clinics, behavioral health care, and rehabilitation services. It is located in Orange, CA, and serves a diverse population of 3.5 million persons with broad health care needs. With more than 400 specialty and primary care physicians, UCI offers a full scope of acute and general care services. It is also the primary teaching location for UCI medical and nursing students, medical residents, and fellows, and is home to Orange County’s only adult Level I and pediatric Level II trauma centers and the regional burn center.

eConsults Program

We designed the initial eConsults program within UCI’s Allscripts EHR platform. Our information technology (IT) build team developed unique “documents-based” eConsults workflows that simplified the process of initiating requests directly from the EHR and facilitated rapid responses from participating specialties. The requesting provider’s eConsults interface was user-friendly, and referring providers were able to initiate an eConsult easily by selecting the customized eConsult icon from the Allscripts main toolbar. To ensure that all relevant information is provided to the specialists, condition-specific templates are embedded in the requesting provider’s eConsults workflow that allow PCPs to enter a focused, patient-specific clinical question and provide guidance on recommended patient information (eg, health history, laboratory results, and digital images) that may help the specialist provide an informed response. The eConsult templates were adapted from standardized forms developed by partner University of California Health Systems in an initiative funded by the University of California Center for Health Quality and Innovation.

To facilitate timely responses from specialists, an innovative notification system was created in the responding provider’s eConsults workflow to automatically send an email to participating specialists when a new eConsult is requested. The responding provider’s workflow also includes an option for the specialist to decline the eConsult if the case is deemed too complex to be addressed electronically. For every completed eConsult that does not result in an in-person patient evaluation, the requesting provider and responding specialist each receives a modest reimbursement, which was initially paid by UCI Health System funds.

Implementation

The design and implementation of the eConsults program began in November 2014, and was guided by a steering committee that included the chair of the department of medicine, chief medical information officer, primary care and specialty physician leads, IT build team, and a project manager. Early on, members of this committee engaged UCI leadership to affirm support for the program and obtain the IT resources needed to build the eConsults workflow. Regular steering committee meetings were established to discuss the design of the workflow, adapt the clinical content of the referral templates, and develop a provider reimbursement plan. After completion of the workflow build, the eConsults system was tested to identify failure points and obtain feedback from users. Prior to going live, the eConsults program was publicized by members of the steering committee through meetings with primary care groups and email communications. Committee members also hosted in-person training and orientation sessions with PCPs and participating specialists, and distributed tip sheets summarizing the steps to complete the PCP and specialist eConsult workflows.

The eConsults workflow build, testing, and launch were completed within 5 months (April 2015; Figure 1). eConsults went live in the 3 initial specialties (endocrinology, cardiology, and rheumatology) that were interested in participating in the first wave of the program. UCI’s eConsults service has subsequently expanded to 17 total specialties (allergy, cardiology, dermatology, endocrinology, gastroenterology, geriatrics, gynecology, hematology, hepatology, infectious disease, nephrology, neurology, palliative care, psychiatry, pulmonary, rheumatology, and sports medicine).

Two and half years after the eConsults program was implemented in Allscripts, UCI adopted a new EHR platform, Epic. By this time, the eConsults service had grown into a mature program with greater numbers of PCP users and submitted eConsults (Figure 2). Using our experience with the Allscripts build, our IT team was able to efficiently transition the eConsults service to the new EHR system. In contrast to the “documents-based” eConsult workflows on Allscripts, our IT team utilized an “orders-based” strategy on Epic, which followed a more traditional approach to requesting a consultation. We re-launched the service in Epic within 3 months (February 2018). However, both platforms utilized user-friendly workflows to achieve similar goals, and the program has continued to grow with respect to the number of users and eConsults.

Measurement/Analysis

The impact of the program was assessed by continuously evaluating usage and outcomes. Measures used to track usage included the number of PCP users, the number of submitted eConsult requests per PCP, and the number of requests per specialty. The response time for eConsult requests and the self-reported amount of time spent by specialists on the response were also tracked. Outcome measures included the specialist recommendation (eg, in-office visit, consultation avoided) and physician feedback. Provider satisfaction was primarily obtained by soliciting feedback from individual eConsult users.

Implementation of this eConsults program constituted a quality improvement activity and did not require Institutional Review Board review.

Since the program was launched in April 2015, more than 1400 eConsults have been completed across 17 specialties (Figure 3). There were 654 completed eConsults on the Allscripts platform, and 808 eConsults have been completed using the Epic platform to date. The busiest eConsult specialties were endocrinology (receiving 276, or 19%, of the eConsults requests), hematology (receiving 249 requests, or 17%), infectious disease (receiving 244 requests, or 17% ), and cardiology (receiving 148 requests, or 10%).

The self-reported amount of time specialists spent on the response was different between the 2 EHR systems (Figure 4). On Allscripts, specialists reported that 23% of eConsults took 10 minutes or less to complete, 47% took 11 to 20 minutes, 23% took 21 to 30 minutes, and 7% took more than 30 minutes. On Epic, specialists reported that 42% of eConsults took 10 minutes or less to complete, 44% took 11 to 20 minutes, 12% took 21 to 30 minutes, and 2% took more than 30 minutes. This difference in time spent fielding eConsults likely represents the subtle nuances between Allscripts’ “documents-based” and Epic’s “orders-based” workflows.

As a result of the automated notification system that was introduced early in the eConsults implementation process on Allscripts, the specialty response times were much faster than the expected 3 business days’ turnaround goal instituted by the Center for Health Quality and Innovation initiative, regardless of the EHR platform used. In fact, the average turnaround time for an eConsult response across all specialties was 1 business day, which was similar for both EHR systems (Figure 5). Furthermore, more than 50% of the eConsults on both EHR systems received specialist responses within the same day of the eConsult request (63% on Allscripts, 54% on Epic). There was a small decrease in the percentage of same-day responses when we transitioned to Epic, likely because the functionality of an automated notification email could not be restored in Epic. Regardless, the specialty response times on Epic remained expeditious, likely because the automated notifications on Allscripts instilled good practices for the specialists, and regularly checking for new eConsult requests became an ingrained behavior.

Our most important finding was that approximately 80% of eConsult requests were addressed without the need for an in-office visit with a specialist. This measure was similar for both EHR platforms (83% on Allscripts and 78% on Epic).

Provider feedback has been overwhelmingly positive. PCPs are impressed with the robust educational content of the eConsult responses, since the goal for specialists is to justify their recommendations. Specialists appreciate the convenience and efficiency that eConsults offer, as well as the improved communication and collaboration among physicians. eConsults have been especially beneficial to PCPs at UCI’s Family Health Centers, who are now able to receive subspecialty consultations from UCI specialists despite insurance barriers.

Discussion

Our eConsults program uniquely contrasts with other programs because UCI is likely the only academic medical center to have experience in successfully incorporating eConsults into 2 different EHR systems: initial development of the eConsults workflow in UCI’s existing Allscripts EHR platform, and subsequently transitioning a mature eConsults program to a new EHR system when the institution adopted Epic.

We measured the impact of the eConsults program on access to care by the response time for eConsult requests and the percentage of eConsults that averted an in-office visit with a specialist. We found that the eConsults program at UCI provided our PCPs access to specialist consultations in a timely manner, with much shorter response times than standard in-person referrals. The average turnaround time for an eConsult response we reported is consistent with findings from other studies.^12-15 Additionally, our program was able to address about 80% of its eConsults electronically, helping to reduce unnecessary in-person specialist referrals. In the literature, the percentage of eConsults that avoided an in-person specialist visit varies widely.^8,12-16

We reported very positive feedback from both PCPs and specialists on UCI’s eConsults service. Similarly, other studies described PCP satisfaction with their respective eConsults programs to be uniformly high,^{8,9,13,14,17-19} though some reported that the level of satisfaction among specialists was more varied.^18-21

Lessons Learned

The successful design and implementation of our eConsults program began with assembling the right clinical champions and technology partners for our steering committee. Establishing regular steering committee meetings helped maintain an appropriate timeline for completion of different aspects of the project. Engaging support from UCI’s leadership also provided us with a dedicated IT team that helped us with the build, training resources, troubleshooting issues, and reporting for the project.

Our experience with implementing the eConsults program on 2 different EHR systems highlighted the importance of creating efficient, user-friendly workflows to foster provider adoption and achieve sustainability. Allscripts’ open platform gave our IT team the ability to create a homegrown solution to implementing an eConsult model that was simple and easy to use. The Epic platform’s interoperability allowed us to leverage our learnings from the Allscripts build to efficiently implement eConsults in Epic.

We also found that providing modest incentive payments or reimbursements to both PCPs and specialists for each completed eConsult helps with both adoption and program sustainability. Initially, credit for the eConsult work was paid by internal UCI Health System funds. Two payers, UC Care (a preferred provider organization plan created just for the University of California) and more recently, the Centers for Medicare & Medicaid Services, have agreed to reimburse for outpatient eConsults. Securing additional payers for reimbursement of the eConsult service will not only ensure the program’s long-term sustainability, but also represents an acknowledgment of the value of eConsults in supporting access to care.

Applicability

Other health care settings that are experiencing issues with specialty care access can successfully implement their own eConsults program by employing strategies similar to those described in this report—assembling the right team, creating user-friendly workflows, and providing incentives. Our advice for successful implementation is to clearly communicate your goals to all involved, including primary care, specialists, leadership, and IT partners, and establish with these stakeholders the appropriate support and resources needed to facilitate the development of the program and overcome any barriers to adoption.

Current Status and Future Directions

Our future plans include continuing to optimize the Epic eConsult backend build and workflows using our experience in Allscripts. We have implemented eConsult workflows for use by graduate medical education trainees and advanced practice providers, with attending supervision. Further work is in progress to optimize these workflows, which will allow for appropriate education and supervision without delaying care. Furthermore, we plan to expand the program to include inpatient-to-inpatient and emergency department-to-inpatient eConsults. We will continue to expand the eConsults program by offering additional specialties, engage providers to encourage ongoing participation, and maximize PCP use by continuing to market the program through regular newsletters and email communications. Finally, the eConsults has served as an effective, important resource in the current era of COVID-19 in several ways: it allows for optimization of specialty input in patient care delivery without subjecting more health care workers to unnecessary exposure; saves on utilization of precious personal protective equipment; and enhances our ability to deal with a potential surge by providing access to specialists remotely and electronically all hours of the day, thus expanding care to the evening and weekend hours.

Many patients experience increased wait times for a visit with a specialist due to poor communication between providers, insufficient guidance on the information or diagnostic results needed by specialists, and lack of care coordination.^4-6 One promising approach to overcome these challenges is the use of an electronic consultation, or eConsult, in place of a standard in-person referral. An eConsult is an asynchronous, non-face-to-face, provider-to-provider exchange using a secure electronic communication platform. For appropriate referral problems, the patient is able to receive timely access to specialist expertise through electronic referral by their PCP,^7-9 and avoid the time and costs associated with a visit to the specialist,^10,11 such as travel, missed work, co-pays, and child-care expenses. Clinical questions addressed using an eConsult system subsequently free up office visit appointment slots, improving access for patients requiring in-office evaluation.^8,12

Orange County’s only academic health system, the University of California, Irvine (UCI), serves a population of 3.5 million, and its principal priority is providing the communities in the county (which is the sixth largest in United States) and the surrounding region with the highest quality health care possible. Thus, UCI aimed to improve its referral processes and provide timely access to specialty care for its patients by implementing an eConsults program that allows PCPs to efficiently receive specialist recommendations on referral problems that do not require the specialist to evaluate the patient in person. This report describes our experiences with developing and implementing a custom-built eConsults workflow in UCI’s prior electronic health record (EHR) platform, Allscripts, and subsequently transitioning our mature eConsults program to a new EHR system when UCI adopted Epic. UCI is likely the only academic medical center to have experience in successfully implementing eConsults into 2 different EHR systems.

Setting

UCI’s medical center is a 417-bed acute care hospital providing tertiary and quaternary care, ambulatory and specialty medical clinics, behavioral health care, and rehabilitation services. It is located in Orange, CA, and serves a diverse population of 3.5 million persons with broad health care needs. With more than 400 specialty and primary care physicians, UCI offers a full scope of acute and general care services. It is also the primary teaching location for UCI medical and nursing students, medical residents, and fellows, and is home to Orange County’s only adult Level I and pediatric Level II trauma centers and the regional burn center.

eConsults Program

We designed the initial eConsults program within UCI’s Allscripts EHR platform. Our information technology (IT) build team developed unique “documents-based” eConsults workflows that simplified the process of initiating requests directly from the EHR and facilitated rapid responses from participating specialties. The requesting provider’s eConsults interface was user-friendly, and referring providers were able to initiate an eConsult easily by selecting the customized eConsult icon from the Allscripts main toolbar. To ensure that all relevant information is provided to the specialists, condition-specific templates are embedded in the requesting provider’s eConsults workflow that allow PCPs to enter a focused, patient-specific clinical question and provide guidance on recommended patient information (eg, health history, laboratory results, and digital images) that may help the specialist provide an informed response. The eConsult templates were adapted from standardized forms developed by partner University of California Health Systems in an initiative funded by the University of California Center for Health Quality and Innovation.

To facilitate timely responses from specialists, an innovative notification system was created in the responding provider’s eConsults workflow to automatically send an email to participating specialists when a new eConsult is requested. The responding provider’s workflow also includes an option for the specialist to decline the eConsult if the case is deemed too complex to be addressed electronically. For every completed eConsult that does not result in an in-person patient evaluation, the requesting provider and responding specialist each receives a modest reimbursement, which was initially paid by UCI Health System funds.

Implementation

The design and implementation of the eConsults program began in November 2014, and was guided by a steering committee that included the chair of the department of medicine, chief medical information officer, primary care and specialty physician leads, IT build team, and a project manager. Early on, members of this committee engaged UCI leadership to affirm support for the program and obtain the IT resources needed to build the eConsults workflow. Regular steering committee meetings were established to discuss the design of the workflow, adapt the clinical content of the referral templates, and develop a provider reimbursement plan. After completion of the workflow build, the eConsults system was tested to identify failure points and obtain feedback from users. Prior to going live, the eConsults program was publicized by members of the steering committee through meetings with primary care groups and email communications. Committee members also hosted in-person training and orientation sessions with PCPs and participating specialists, and distributed tip sheets summarizing the steps to complete the PCP and specialist eConsult workflows.

The eConsults workflow build, testing, and launch were completed within 5 months (April 2015; Figure 1). eConsults went live in the 3 initial specialties (endocrinology, cardiology, and rheumatology) that were interested in participating in the first wave of the program. UCI’s eConsults service has subsequently expanded to 17 total specialties (allergy, cardiology, dermatology, endocrinology, gastroenterology, geriatrics, gynecology, hematology, hepatology, infectious disease, nephrology, neurology, palliative care, psychiatry, pulmonary, rheumatology, and sports medicine).

Two and half years after the eConsults program was implemented in Allscripts, UCI adopted a new EHR platform, Epic. By this time, the eConsults service had grown into a mature program with greater numbers of PCP users and submitted eConsults (Figure 2). Using our experience with the Allscripts build, our IT team was able to efficiently transition the eConsults service to the new EHR system. In contrast to the “documents-based” eConsult workflows on Allscripts, our IT team utilized an “orders-based” strategy on Epic, which followed a more traditional approach to requesting a consultation. We re-launched the service in Epic within 3 months (February 2018). However, both platforms utilized user-friendly workflows to achieve similar goals, and the program has continued to grow with respect to the number of users and eConsults.

Measurement/Analysis

The impact of the program was assessed by continuously evaluating usage and outcomes. Measures used to track usage included the number of PCP users, the number of submitted eConsult requests per PCP, and the number of requests per specialty. The response time for eConsult requests and the self-reported amount of time spent by specialists on the response were also tracked. Outcome measures included the specialist recommendation (eg, in-office visit, consultation avoided) and physician feedback. Provider satisfaction was primarily obtained by soliciting feedback from individual eConsult users.

Implementation of this eConsults program constituted a quality improvement activity and did not require Institutional Review Board review.

Since the program was launched in April 2015, more than 1400 eConsults have been completed across 17 specialties (Figure 3). There were 654 completed eConsults on the Allscripts platform, and 808 eConsults have been completed using the Epic platform to date. The busiest eConsult specialties were endocrinology (receiving 276, or 19%, of the eConsults requests), hematology (receiving 249 requests, or 17%), infectious disease (receiving 244 requests, or 17% ), and cardiology (receiving 148 requests, or 10%).

The self-reported amount of time specialists spent on the response was different between the 2 EHR systems (Figure 4). On Allscripts, specialists reported that 23% of eConsults took 10 minutes or less to complete, 47% took 11 to 20 minutes, 23% took 21 to 30 minutes, and 7% took more than 30 minutes. On Epic, specialists reported that 42% of eConsults took 10 minutes or less to complete, 44% took 11 to 20 minutes, 12% took 21 to 30 minutes, and 2% took more than 30 minutes. This difference in time spent fielding eConsults likely represents the subtle nuances between Allscripts’ “documents-based” and Epic’s “orders-based” workflows.

As a result of the automated notification system that was introduced early in the eConsults implementation process on Allscripts, the specialty response times were much faster than the expected 3 business days’ turnaround goal instituted by the Center for Health Quality and Innovation initiative, regardless of the EHR platform used. In fact, the average turnaround time for an eConsult response across all specialties was 1 business day, which was similar for both EHR systems (Figure 5). Furthermore, more than 50% of the eConsults on both EHR systems received specialist responses within the same day of the eConsult request (63% on Allscripts, 54% on Epic). There was a small decrease in the percentage of same-day responses when we transitioned to Epic, likely because the functionality of an automated notification email could not be restored in Epic. Regardless, the specialty response times on Epic remained expeditious, likely because the automated notifications on Allscripts instilled good practices for the specialists, and regularly checking for new eConsult requests became an ingrained behavior.

Our most important finding was that approximately 80% of eConsult requests were addressed without the need for an in-office visit with a specialist. This measure was similar for both EHR platforms (83% on Allscripts and 78% on Epic).

Provider feedback has been overwhelmingly positive. PCPs are impressed with the robust educational content of the eConsult responses, since the goal for specialists is to justify their recommendations. Specialists appreciate the convenience and efficiency that eConsults offer, as well as the improved communication and collaboration among physicians. eConsults have been especially beneficial to PCPs at UCI’s Family Health Centers, who are now able to receive subspecialty consultations from UCI specialists despite insurance barriers.

Discussion

Our eConsults program uniquely contrasts with other programs because UCI is likely the only academic medical center to have experience in successfully incorporating eConsults into 2 different EHR systems: initial development of the eConsults workflow in UCI’s existing Allscripts EHR platform, and subsequently transitioning a mature eConsults program to a new EHR system when the institution adopted Epic.

We measured the impact of the eConsults program on access to care by the response time for eConsult requests and the percentage of eConsults that averted an in-office visit with a specialist. We found that the eConsults program at UCI provided our PCPs access to specialist consultations in a timely manner, with much shorter response times than standard in-person referrals. The average turnaround time for an eConsult response we reported is consistent with findings from other studies.^12-15 Additionally, our program was able to address about 80% of its eConsults electronically, helping to reduce unnecessary in-person specialist referrals. In the literature, the percentage of eConsults that avoided an in-person specialist visit varies widely.^8,12-16

We reported very positive feedback from both PCPs and specialists on UCI’s eConsults service. Similarly, other studies described PCP satisfaction with their respective eConsults programs to be uniformly high,^{8,9,13,14,17-19} though some reported that the level of satisfaction among specialists was more varied.^18-21

Lessons Learned

The successful design and implementation of our eConsults program began with assembling the right clinical champions and technology partners for our steering committee. Establishing regular steering committee meetings helped maintain an appropriate timeline for completion of different aspects of the project. Engaging support from UCI’s leadership also provided us with a dedicated IT team that helped us with the build, training resources, troubleshooting issues, and reporting for the project.

Our experience with implementing the eConsults program on 2 different EHR systems highlighted the importance of creating efficient, user-friendly workflows to foster provider adoption and achieve sustainability. Allscripts’ open platform gave our IT team the ability to create a homegrown solution to implementing an eConsult model that was simple and easy to use. The Epic platform’s interoperability allowed us to leverage our learnings from the Allscripts build to efficiently implement eConsults in Epic.

We also found that providing modest incentive payments or reimbursements to both PCPs and specialists for each completed eConsult helps with both adoption and program sustainability. Initially, credit for the eConsult work was paid by internal UCI Health System funds. Two payers, UC Care (a preferred provider organization plan created just for the University of California) and more recently, the Centers for Medicare & Medicaid Services, have agreed to reimburse for outpatient eConsults. Securing additional payers for reimbursement of the eConsult service will not only ensure the program’s long-term sustainability, but also represents an acknowledgment of the value of eConsults in supporting access to care.

Applicability

Other health care settings that are experiencing issues with specialty care access can successfully implement their own eConsults program by employing strategies similar to those described in this report—assembling the right team, creating user-friendly workflows, and providing incentives. Our advice for successful implementation is to clearly communicate your goals to all involved, including primary care, specialists, leadership, and IT partners, and establish with these stakeholders the appropriate support and resources needed to facilitate the development of the program and overcome any barriers to adoption.

Current Status and Future Directions

Our future plans include continuing to optimize the Epic eConsult backend build and workflows using our experience in Allscripts. We have implemented eConsult workflows for use by graduate medical education trainees and advanced practice providers, with attending supervision. Further work is in progress to optimize these workflows, which will allow for appropriate education and supervision without delaying care. Furthermore, we plan to expand the program to include inpatient-to-inpatient and emergency department-to-inpatient eConsults. We will continue to expand the eConsults program by offering additional specialties, engage providers to encourage ongoing participation, and maximize PCP use by continuing to market the program through regular newsletters and email communications. Finally, the eConsults has served as an effective, important resource in the current era of COVID-19 in several ways: it allows for optimization of specialty input in patient care delivery without subjecting more health care workers to unnecessary exposure; saves on utilization of precious personal protective equipment; and enhances our ability to deal with a potential surge by providing access to specialists remotely and electronically all hours of the day, thus expanding care to the evening and weekend hours.

Higher cardiovascular risk burden, as measured by the Framingham General Cardiovascular Risk Score (FGCRS), is associated with neurodegenerative signs in the brain and may predict cognitive decline over time.

“In the absence of effective treatments for dementia, we need to monitor and control cardiovascular risk burden as a way to maintain patient’s cognitive health as they age,” said Weili Xu, PhD, Department of Epidemiology and Biostatistics, School of Public Health, Tianjin Medical University, Tianjin, China, in a press release.

“Given the progressive increase in the number of dementia cases worldwide, our findings have both clinical and public health relevance.”

Dr. Xu and first author Ruixue Song, MSc, also from Tianjin Medical University, published their findings online ahead of print May 18 in the Journal of the American College of Cardiology.

The World Health Organization projects that up to 82 million people will have dementia by 2050. Given the lack of effective treatments for dementia, identifying modifiable risk factors for cognitive decline and aggressively managing them is an increasingly appealing strategy.
 

Assessing cardiovascular risk and cognition

The researchers followed 1,588 dementia-free participants from the Rush Memory and Aging Project for 21 years (median, 5.8 years). FGCRS was assessed at baseline and categorized into tertiles (lowest, middle, and highest). Mean age of the studied population was 79.5 years, 75.8% of participants were female, and mean Framingham score was 15.6 (range, 4 to 28).

Annual evaluations included assessment of episodic memory (memory of everyday events), semantic memory (long-term memory), working memory (short-term memory), visuospatial ability (capacity to identify visual and spatial relationships among objects), and perceptual speed (ability to accurately and completely compare letters, numbers, objects, pictures, or patterns) using 19 tests to derive a composite score.

A subsample (n = 378) of participants underwent MRI, and structural total and regional brain volumes were estimated.

Linear regression was used to estimate beta-coefficients for the relationship between cardiovascular risk burden at baseline and longitudinally. If the beta-coefficient is negative, the interpretation is that for every 1-unit increase in the predictor variable (FGCRS), the outcome variable (cognitive function) will decrease by the beta-coefficient value.

At baseline, higher FGCRS was related to small but consistent (although not usually statistically significant) decreases in hippocampal volume, gray matter, and total brain volume.

Considered longitudinally, participants in the highest-risk tertile of FGCRS experienced faster decline in global cognition (beta = −0.019), episodic memory (beta = −0.023), working memory (beta = −0.021), and perceptual speed (beta = −0.027) during follow-up (P < .05 for all) than those in the lowest-risk tertile.

The declines in semantic memory (beta = –0.012) and visuospatial ability (beta = –0.010) did not reach statistical significance.

Bringing dementia prevention into the exam room early

Commenting on the research, Costantino Iadecola, MD, director of the Feil Family Brain and Mind Research Institute at Weill Cornell Medicine in New York City, said the study has immediate clinical usefulness.

“The link between the cardiovascular risk factors and dementia is well known, but in your doctor’s office, that link is not seen. If your GP or cardiologist sees you with high blood pressure, he’s not immediately going to think about the risk of dementia 20 years later,” said Dr. Iadecola.

“What this study does is it directly links a simple score that’s commonly used to assess cardiovascular risk to dementia risk, which can be used to counsel patients and, hopefully, reduce the risk of both cardiovascular disease and cognitive disorders.”

Dr. Iadecola wrote an editorial together with Neal S. Parikh, MD, MS, also from Weill Cornell Medicine, that accompanied the findings of the trial.

Even neurologists sometimes fail to make the connection between vascular risk and dementia, he said. “They think that by making a stroke patient move their hand better, they’re treating them, but 30% of stroke patients get dementia 6 or 8 months later and they’re missing this link between cerebrovascular pathology and dementia.

Dr. Iadecola is one of 26 experts who authored the recent Berlin Manifesto, an effort led by Vladimir Hachinski, MD, professor of neurology and epidemiology at Western University in Ontario, Canada, to raise awareness of the link between cardiovascular and brain health.

Dr. Hachinski coined the term “brain attack” and devised the Hachinski Ischemic Score that remains the standard for identifying a vascular component of cognitive impairment.

The current study has some strengths and limitations, noted Dr. Iadecola. The average age of participants was 80 years, which is appropriate given the high risk for cognitive decline at this age, but the generalizability of the study may be limited given that most participants were white women.

Going forward, he said, rigorous studies are needed to confirm these findings and to determine how to best prevent dementia through treatment of individual cardiovascular risk factors.

Dr. Xu has received grants from nonindustry entities, including the Swedish Research Council and the National Natural Science Foundation of China. The study was funded by the European Union’s Horizon 320230 research and innovation program. Dr. Iadecola is a member of the scientific advisory board for Broadview Ventures.

The American Heart Association/American Stroke Association has developed a “conceptual framework” to assist emergency medical service (EMS) providers and in-hospital triage teams handle suspected cases of acute stroke during the ongoing COVID-19 crisis and future pandemics. A key goal is to ensure timely transfer of patients while minimizing the risk of infectious exposure for EMS personnel, coworkers, and other patients, the writing group says.

“Acute ischemic stroke is still a highly devastating disease and the Time Is Brain paradigm remains true during the COVID-19 pandemic as well,” said writing group chair Mayank Goyal, MD, of the University of Calgary (Alta.)

“We have highly effective and proven treatments available. As such, treatment delays due to additional screening requirements and personal protection equipment (PPE) should be kept at a minimum,” Dr. Goyal said.

“Practicing COVID-19 stroke work flows, through simulation training, can help to reduce treatment delays, minimize the risk of infectious exposure for patients and staff, and help alleviate stress,” he added.
 

A new layer of complexity

The guidance statement, Prehospital Triage of Acute Stroke Patients During the COVID-19 Pandemic, was published online May 13 in the journal Stroke.

“The need to limit infectious spread during the COVID-19 pandemic has added a new layer of complexity to prehospital stroke triage and transfer,” the writing group noted. “Timely and enhanced” communication between EMS, hospitals, and local coordinating authorities are critical, especially ambulance-and facility-based telestroke networks, they wrote.

The main factors to guide the triage decision are the likelihood of a large vessel occlusion; the magnitude of additional delays because of interhospital transfer and work flow efficiency at the primary stroke center or acute stroke ready hospital; the need for advanced critical care resources; and the available bed, staff, and PPE resources at the hospitals.

The group said it “seems reasonable” to lower the threshold to bypass hospitals that can’t provide acute stroke treatment in favor of transporting to a hospital that is “stroke ready,” particularly in patients likely to require advanced care. They cautioned, however, that taking all acute stroke patients to a comprehensive stroke center could overwhelm these centers and lead to clustering of COVID-19 patients.

They said it is equally important to ensure “necessary transfers” of stroke patients who would benefit from endovascular therapy or neurocritical care and avoid unnecessary patient transfers. “Doing so will likely require local hospital boards and health care authorities to collaborate and establish local guidelines and protocols,” the writing group said.

“During the COVID-19 pandemic, it is more important than ever to ensure that stroke patients are taken to the right hospital that can meet their urgent needs at the outset,” Dr. Goyal commented in an AHA news release.

The writing group emphasized that the principles put forth in the document are intended as suggestions rather than strict rules and will be adapted and updated to meet the evolving needs during the COVID-19 crisis and future pandemics.

“The process of improving stroke work flow and getting the correct patient to the correct hospital fast is dependent on training, protocols, simulation, technology, and – probably most importantly – teamwork. These principles are extremely important during the current pandemic but will be useful in improving stroke care afterwards as well,” Dr. Goyal said.

This research had no commercial funding. Members of the writing committee are on several AHA/ASA Council Science Subcommittees, including the Emergency Neurovascular Care, the Telestroke, and the Neurovascular Intervention committees. Goyal is a consultant for Medtronic, Stryker, Microvention, GE Healthcare, and Mentice. A complete list of author disclosures is available with the original article.

“We have highly effective and proven treatments available. As such, treatment delays due to additional screening requirements and personal protection equipment (PPE) should be kept at a minimum,” Dr. Goyal said.

“Practicing COVID-19 stroke work flows, through simulation training, can help to reduce treatment delays, minimize the risk of infectious exposure for patients and staff, and help alleviate stress,” he added.
 

A new layer of complexity

The guidance statement, Prehospital Triage of Acute Stroke Patients During the COVID-19 Pandemic, was published online May 13 in the journal Stroke.

“The need to limit infectious spread during the COVID-19 pandemic has added a new layer of complexity to prehospital stroke triage and transfer,” the writing group noted. “Timely and enhanced” communication between EMS, hospitals, and local coordinating authorities are critical, especially ambulance-and facility-based telestroke networks, they wrote.

The main factors to guide the triage decision are the likelihood of a large vessel occlusion; the magnitude of additional delays because of interhospital transfer and work flow efficiency at the primary stroke center or acute stroke ready hospital; the need for advanced critical care resources; and the available bed, staff, and PPE resources at the hospitals.

The group said it “seems reasonable” to lower the threshold to bypass hospitals that can’t provide acute stroke treatment in favor of transporting to a hospital that is “stroke ready,” particularly in patients likely to require advanced care. They cautioned, however, that taking all acute stroke patients to a comprehensive stroke center could overwhelm these centers and lead to clustering of COVID-19 patients.

They said it is equally important to ensure “necessary transfers” of stroke patients who would benefit from endovascular therapy or neurocritical care and avoid unnecessary patient transfers. “Doing so will likely require local hospital boards and health care authorities to collaborate and establish local guidelines and protocols,” the writing group said.

“During the COVID-19 pandemic, it is more important than ever to ensure that stroke patients are taken to the right hospital that can meet their urgent needs at the outset,” Dr. Goyal commented in an AHA news release.

The writing group emphasized that the principles put forth in the document are intended as suggestions rather than strict rules and will be adapted and updated to meet the evolving needs during the COVID-19 crisis and future pandemics.

“The process of improving stroke work flow and getting the correct patient to the correct hospital fast is dependent on training, protocols, simulation, technology, and – probably most importantly – teamwork. These principles are extremely important during the current pandemic but will be useful in improving stroke care afterwards as well,” Dr. Goyal said.

This research had no commercial funding. Members of the writing committee are on several AHA/ASA Council Science Subcommittees, including the Emergency Neurovascular Care, the Telestroke, and the Neurovascular Intervention committees. Goyal is a consultant for Medtronic, Stryker, Microvention, GE Healthcare, and Mentice. A complete list of author disclosures is available with the original article.

The American Heart Association/American Stroke Association has developed a “conceptual framework” to assist emergency medical service (EMS) providers and in-hospital triage teams handle suspected cases of acute stroke during the ongoing COVID-19 crisis and future pandemics. A key goal is to ensure timely transfer of patients while minimizing the risk of infectious exposure for EMS personnel, coworkers, and other patients, the writing group says.

The American Academy of Neurology has published a position statement providing ethical guidance for neurologists caring for patients with neurologic disorders during the COVID-19 pandemic. The document, which was published online May 15 in Neurology, reviews adaptations to the inpatient and outpatient settings and addresses the need to develop protocols for the allocation of scarce medical resources. The guidance is the product of a joint committee of the AAN, the American Neurological Association, the Child Neurology Society, and the Neurocritical Care Society Ethics Committee.

“Now is one of the most challenging times of our careers as neurologists,” said James C. Stevens, MD, president of the AAN, in a press release. “Clinics and hospitals are adapting to caring for the most ill, managing scarce resources, and trying to protect people without the disease. As neurologists, we must continue to adapt our daily practice, continue to care for our most ill neurology patients, and help contribute to the care of those afflicted with COVID-19.”
 

The role of telehealth

The authors recommended that ordinary appointments be held using telehealth, which, they say, already has become part of patient care. Telehealth enables neurologists to continue providing care while reducing the risk of exposure to and spread of SARS-CoV-2. The disadvantages of telehealth are that it limits physical examinations and behavioral health examinations, the authors acknowledged. “Each clinician should decide, in concert with his or her patient, if an in-person evaluation warrants the risk of an encounter,” according to the guidance.

Neurologists also should advise their patients that their neurologic condition could affect their relative risk of hospitalization and death resulting from COVID-19. Patients with multiple sclerosis or myasthenia gravis, for example, may be receiving corticosteroids or immunomodulatory therapies that make them more vulnerable to COVID-19 infection. “Even if desired services are available, neurologists and their patients ought to consider whether their care plans can safely be delayed in order to mitigate risk,” wrote the authors. Neurologists must try to maintain the customary standard of care, however, for patients with neurologic disease severe enough to warrant hospitalization, such as stroke or epilepsy.
 

The potential need for triage

Resources such as ventilators and ICU beds are limited, and health care facilities have had to triage them during the pandemic. Patients with a neurologic disease that decreases their likelihood of survival from a respiratory illness may not be offered these resources. Neurologists should discuss with patients and decision makers the ways in which reduced resources might affect patient care. Neurologists must “be aware of the burden of disease in their local community and how healthcare leaders plan on coping with a surge,” according to the guidance.

Advance directives, which should be a standard part of clinical care, take on increased importance during the pandemic. Patients who have not completed advance care planning documents should be encouraged to do so, according to the authors. These documents include patients’ preferences for “do not attempt resuscitation” status. Nevertheless, “we must assure patients with chronic illness that diminished resources in this healthcare crisis will not restrict their access to comfort and palliative care,” the document states.
 

Scarce resource allocation protocols

In the event that a surge in patients overwhelms a hospital’s contingencies and forces it to operate in crisis mode, it should have a scarce resource allocation protocol in place.

“This will surely be the most challenging aspect of patient care during this pandemic public health emergency,” wrote the authors. To ensure transparency and to mitigate the emotional effect of these decisions on patients and clinicians, scarce resource allocation protocols should be developed by teams that include intensivists, clinical ethicists, and nursing representatives who are not directly involved in the care of the critically ill patients. The goal of these protocols is to maximize the number of lives saved. They generally include an initial patient assessment followed by regular reevaluations to determine whether patients using scarce resources are benefiting less than other patients who need the same resources. The protocols should consider not only patients with COVID-19 infection, but also patients with stroke, traumatic injury, influenza, and heart failure who may need the same resources. Race, gender, ethnicity, socioeconomics, and perceived social worth should not influence care decisions, according to the guidance. Validated mortality prediction scales, such as the Glasgow Outcome Scale, can contribute to care decisions. Obtaining community input into these protocols will ensure trust in the health care system.

“If the situation necessitates hard decisions, we need to be fair, objective, transparent, and adamantly preserve our professional integrity,” wrote the authors. “Through it all, we owe it to our patients and families, as well as ourselves, to maintain our own health and wellness.”

The guidance was developed without funding, and the authors reported no relevant disclosures.

A meta-analysis of relevant clinical trials has found that lowering blood pressure with antihypertensive agents was statistically significantly associated with reducing the risk of dementia or cognitive impairment, though the risk reduction was modest.

“Although observational studies report hypertension to be an important risk factor for dementia, the benefit of blood pressure lowering on dementia or cognitive impairment in clinical trials is modest and lower than the risk reduction for stroke,” wrote Diarmaid Hughes, MB, of the NUI Galway and Saolta University Hospital Group in Galway, Ireland, and coauthors. They added, however, that “these findings have the potential to inform public health strategies to reduce the burden of dementia globally.” The study was published online ahead of print May 19 in JAMA.
 

A rich data set

To assess the relationship between lowering blood pressure and cognitive issues, the researchers performed a systemic search of randomized, clinical trials that compared blood pressure lowering via antihypertensive agents with a control, had at least 1 year of follow-up, included more than 1,000 participants, and reported on either dementia, cognitive impairment, cognitive decline, or a change in cognitive test scores as outcomes. Of the 14 studies deemed eligible, 12 reported either the incidence of dementia (n = 9) or a composite of dementia or cognitive impairment (n = 3) at follow-up and thus were included in the primary meta-analysis. The other two studies were used for secondary outcomes only.

The studies included 96,158 participants in total – 42.2% were women – and their mean age was 69 years. At baseline, participants’ mean systolic blood pressure was 154 mm Hg and their mean diastolic blood pressure was 83.3 mm Hg. The mean duration of follow-up was 49.24 months.

In the 12 trials that reported dementia or cognitive impairment, blood pressure lowering via antihypertensive agents, compared with control, was significantly associated with a reduction in those two outcomes (7.0% vs. 7.5% over a mean trial follow-up of 4.1 years; odds ratio, 0.93; 95% confidence interval, 0.88-0.98; absolute risk reduction, 0.39%; 95% CI, 0.09%-0.68%). Blood pressure lowering, compared with control, was also significantly associated with a reduction in cognitive decline (20.2% vs. 21.1% over a mean trial follow-up of 4.1 years; OR, 0.93; 95% CI, 0.88-0.99; ARR, 0.71%; 95% CI, 0.19%-1.2%) in the eight trials that reported it as an outcome. An analysis of the eight trials that reported a change in cognitive scores did not find a significant association between that outcome and blood pressure lowering.
 

Subpopulations should be examined

“This is a very broad brush stroke study, albeit a definitive one,” Richard J. Caselli, MD, of the Mayo Clinic in Phoenix said in an interview. “With all the thousands of people in this meta-analysis, there are going to be subpopulations of patients with certain characteristics or common conditions in which blood pressure lowering might have a bigger or a lesser impact on their risk factor. Is there a difference between certain racial groups? Does it matter what antihypertensive strategies are used? You can look at the interactions between blood pressure lowering and other conditions: diabetes, head injuries, air pollution, certain genetic risk factors. There are a number of additional findings that could come from a very rich data set like this.”

The authors acknowledged their study’s limitations, including the challenges of performing a meta-analysis of studies that drew from different populations and had potentially different definitions of dementia, cognitive impairment, and cognitive decline outcomes. In addition, the low incidence of dementia across clinical trials limited the researchers, and its underdetection in trials and the potential of survivor bias for healthier participants with blood pressure reductions were noted as “unmeasured sources of potential error.”

Three authors reported receiving grants or personal fees from the Wellcome Trust and the Health Research Board, the Chief Scientist Office, and Bayer AG, respectively.

Certain patterns of frontal lobe glucose hypometabolism may be associated with higher risk for sudden unexpected death in epilepsy (SUDEP) among patients with refractory focal epilepsy, new research suggests.

“The data provide initial evidence that hypometabolism in certain parts of the frontal cortex may be associated with higher SUDEP risk,” said lead author Maysaa M. Basha, MD, associate professor of neurology and director of the Adult Comprehensive Epilepsy Program, Wayne State University/Detroit Medical Center, in Michigan.

If this research is validated, “it potentially can be used to screen patients for higher SUDEP risk,” she said. The idea is to identify those at high risk and then reduce that risk with more aggressive management of seizures or closer monitoring in certain cases, she added.

The research is being presented online as part of the 2020 American Academy of Neurology (AAN) Science Highlights.
 

Hypometabolism

Dr. Basha and colleagues were encouraged to pursue this new line of research after a pilot [18F]fluorodeoxyglucose positron-emission tomography (FDG-PET) study revealed frontal lobe hypometabolism among patients who subsequently died.

“We wanted to determine if such a metabolic abnormality is associated with SUDEP risk,” said Dr. Basha. She noted that no PET studies have addressed this question, only MRI studies.

In this new study, researchers aimed to identify specific patterns of objectively detected brain glucose metabolic abnormalities in patients with refractory focal epilepsy who were at risk for SUDEP.

The study included 80 patients (45 female patients) aged 16 to 61 years (mean age, 37 years) who underwent FDG-PET as part of their presurgical evaluation for epilepsy surgery. Patients with large brain lesions, such as an infarct or a large tumor, were excluded from the study; such lesions can affect the accuracy of an objective PET analysis, explained Dr. Basha.

The researchers assessed risk for SUDEP using the seven-item SUDEP inventory (SUDEP-7), which was developed as a marker of clinical SUDEP risk. The 0- to 10-point scale is used to evaluate the frequency of tonic-clonic and other seizures, the duration of epilepsy, the use of antiepileptic drugs, and intellectual disability.

The researchers calculated SUDEP-7 inventory scores as closely as possible to FDG-PET assessments. The mean score in the patient population was 3.6.

The investigators divided participants into two subgroups: 22 patients had a SUDEP score of 5 or greater; and 58 had a score of less than 5 (higher scores indicate higher risk for SUDEP).

The researchers compared PET scans of each of these subgroups to PET scans from healthy adults to determine whether they showed common areas of metabolic abnormality. For this, they used an image analytic software program called Statistical Parametric Mapping, which compares group values of metabolic activity measured in small units of the brain (voxels) with statistical methods.

The analysis showed that the higher-risk group displayed a common pattern of hypometabolism in certain brain areas.

“The epilepsy patient subgroup with high SUDEP risk showed areas of decreased metabolism, as compared to the control group, in portions of the frontal cortex,” said Dr. Basha. “The statistically most significant decreases were in the right frontal lobe area—both lateral convexity and medial cortex.”

Dr. Basha added that these group abnormalities were “remarkably similar” to the individual metabolic abnormalities found in the four SUDEP patients in the previous pilot study who underwent PET scanning and who subsequently died.

A similar group analysis showed that the group at low SUDEP risk displayed no common metabolic abnormalities.

MRI findings were normal for 40 patients.

Dr. Basha and colleagues believe that “this is the first PET study assessing the metabolic correlates of SUDEP risk on the group level.”
 

Common feature

Interictal glucose hypometabolism is “common in and around epileptic foci,” noted Dr. Basha. However, this could extend into nonepileptic regions—for example, to remote connected regions where seizures can spread from the primary focus and into subcortical gray matter structures, such the thalamus.

Some of these metabolic abnormalities may indicate subtle, microscopic, structural abnormalities in the affected brain, said Dr. Basha.

Abnormalities that are induced by epilepsy and that result from purely metabolic changes could be partly or fully reversed if seizures are controlled on a long-term basis, she said. “Some metabolic abnormalities can be reversed after better seizure control with antiepileptic drugs, epileptic surgery, or other antiepileptic treatment,” she said.

It’s “quite possible” that the same brain pattern would be evident in children with epilepsy, although her team has not performed the same analysis in a younger pediatric group, said Dr. Basha. She noted that it would be unethical to administer PET scans, which involve radiation, to young, healthy control persons.

It’s too early to recommend that all epilepsy patients undergo FDG-PET scanning to see whether this pattern of brain glucose hypometabolism is present, said Dr. Basha. “But if this is proven to be a good biomarker, the next step would be a prospective study” to see whether this brain marker is a true signal of SUDEP risk.

“I don’t think our single study would do that, but ultimately, that would be the goal,” she added.
 

One more piece of the SUDEP puzzle

Commenting on the study, William Davis Gaillard, MD, president of the American Epilepsy Society and chief of neurology, Children’s National Medical Center, Chevy Chase, Maryland, said this new information provides one more piece of the SUDEP puzzle but doesn’t complete the picture.

The study authors assessed PET scans of a group of patients and found common abnormalities that implicate the right medial frontal cortex. “That’s a pretty reasonable method” of investigation, said Dr. Gaillard.

“The challenge is that they’re looking at people they believe have a risk of SUDEP as opposed to people who died,” said Dr. Gaillard.

But he agreed that the results might signal “a biomarker” that “allows you to identify who’s at high risk, and then you may be able to intervene to save them.”

It’s not clear that people with frontal lobe epilepsy are at greater risk for SUDEP than those with temporal lobe epilepsy, he said.

“What you don’t know is whether this represents people with a seizure focus in that area or this represents a common network implicated in people with diverse forms of focal epilepsy; so you need to do some more work,” he said.

Dr. Gaillard pointed out that other research has implicated regions other than the mesial frontal cortex in SUDEP risk. These regions include the insula, the amygdala, the hippocampus, and the brain stem.

He also noted that the SUDEP-7, which has not been thoroughly validated, is designed for use only in adults.

In his own practice, he asks patients about the frequency of tonic-clonic seizures and whether they occur at night. The number of antiepileptic medications a patient takes reflects the difficulty of controlling seizures and may not be “an independent variable for risk,” said Dr. Gaillard.

“It’s clear one needs a better assessment and better idea of who is at risk,” he said.

The researchers have disclosed no relevant financial relationships.

Certain patterns of frontal lobe glucose hypometabolism may be associated with higher risk for sudden unexpected death in epilepsy (SUDEP) among patients with refractory focal epilepsy, new research suggests.

“The data provide initial evidence that hypometabolism in certain parts of the frontal cortex may be associated with higher SUDEP risk,” said lead author Maysaa M. Basha, MD, associate professor of neurology and director of the Adult Comprehensive Epilepsy Program, Wayne State University/Detroit Medical Center, in Michigan.

If this research is validated, “it potentially can be used to screen patients for higher SUDEP risk,” she said. The idea is to identify those at high risk and then reduce that risk with more aggressive management of seizures or closer monitoring in certain cases, she added.

The research is being presented online as part of the 2020 American Academy of Neurology (AAN) Science Highlights.
 

Hypometabolism

Dr. Basha and colleagues were encouraged to pursue this new line of research after a pilot [18F]fluorodeoxyglucose positron-emission tomography (FDG-PET) study revealed frontal lobe hypometabolism among patients who subsequently died.

“We wanted to determine if such a metabolic abnormality is associated with SUDEP risk,” said Dr. Basha. She noted that no PET studies have addressed this question, only MRI studies.

In this new study, researchers aimed to identify specific patterns of objectively detected brain glucose metabolic abnormalities in patients with refractory focal epilepsy who were at risk for SUDEP.

The study included 80 patients (45 female patients) aged 16 to 61 years (mean age, 37 years) who underwent FDG-PET as part of their presurgical evaluation for epilepsy surgery. Patients with large brain lesions, such as an infarct or a large tumor, were excluded from the study; such lesions can affect the accuracy of an objective PET analysis, explained Dr. Basha.

Yoga as adjunctive therapy for episodic migraine proved superior to conventional medications alone in the randomized, prospective CONTAIN trial, neurologist Rohit Bhatia, MD, and colleagues reported in Neurology.

The structured yoga program resulted in “remarkably improved” outcomes at 3 months of follow-up in CONTAIN, with both headache frequency and use of medications cut in half, compared with baseline, according to the investigators.

Compared with the control group on standard antimigraine medications alone, the yoga group demonstrated significantly greater reductions in pain intensity, headache frequency, pill counts, and validated measures of disability and headache impact on daily life (see graphic).

“The good news is that practicing something as simple and accessible as yoga may help much more than medications alone. And all you need is a mat,” observed Dr. Bhatia, professor of neurology at the All India Institute of Medical Sciences in New Delhi.

The single-center, open-label, blinded-assessment CONTAIN trial included 160 adult episodic migraine patients ages 18-50 years experiencing 4-14 headaches per month. They were randomized to prophylactic and acute rescue medications alone or in combination with yoga instruction by a qualified yoga therapist in a class that met at the medical center 3 days per week for 1 month. This was followed by practice of the hour-long yoga program at home 5 days per week for the next 2 months, with twice-monthly telephone calls from the yoga center to encourage adherence and encouragement to call if questions arose. Both groups received counseling about the importance of lifestyle changes that may help with migraine, including diet, physical activity, adequate sleep, and stress reduction. Outcomes were assessed in an intent-to-treat analysis.

The yoga program included specific relaxation exercises, breathing techniques, meditation, and yoga postures, or asanas. The migraine-tailored program was vetted by yoga experts at five renowned Indian yoga centers.
 

No safety issues arose with the yoga program.

The investigators noted that the 47% reduction in migraine medication pill count and 49% decrease in headache frequency over the course of 3 months in the adjunctive yoga group have important implications, not only in a limited-resource country such as India, but also in the United States, where Americans spend an estimated $3.2 billion annually on prescription and over the counter headache medications, and the indirect cost associated with lost productivity due to migraine has been put at $13 billion per year.

Dr. Bhatia and colleagues speculated that the observed benefits of add-on yoga in migraineurs may involve previously described improved vagal tone and parasympathetic drive coupled with decreased sympathetic tone, increased nitric oxide levels, and loosening of stiff muscles, which can trigger headaches.
 

Real-life goals

Commenting on the research, neurologist Holly Yancy, DO, a headache specialist at the Banner Health - University Medicine Neuroscience Institute in Phoenix, said she was impressed by the high quality of this well-designed, adequately powered study of a complementary and alternative therapy.

“The primary and secondary endpoints were real-life goals of migraine treatment that we strive to achieve in clinical practice – and they were met in the study,” she observed. “To start with a month of in-house yoga classes to instill a baseline competence in yoga prior to transitioning to home practice and to provide resources for ongoing assistance for questions were nice touches.”

She noted that the control group also experienced reductions in migraine frequency, severity, and disability scores, albeit of significantly lesser magnitude than in the yoga group. This underscores how important it is in clinical practice to spend time counseling migraine patients on lifestyle choices.

“A trial such as this provides neurologists and other health care providers with an accessible, evidence-based treatment for migraines that can be used with other preventive treatments to decrease the frequency and the amount of medication their patients are taking. In addition, it is a behavioral therapy that can decrease triggers and potentially help patients cope with pain,” Dr. Yancy said.

“I suspect I’ll not hesitate to recommend yoga as an adjunctive treatment for patients in my clinic that are physically capable. I think it would be logical to try to extrapolate the concept to a chronic migraine population as well, though it would be ideal to base that recommendation on another study conducted with a chronic migraine population.”

Dr. Bhatia and his coinvestigators reported having no financial conflicts regarding their study, funded by the Government of India and the All India Institute of Medical Sciences.

New research shows that almost 5% of older British citizens have potentially serious brain abnormalities, including aneurysms, and about a third have blood test abnormalities. Knowing the expected prevalence of such incidental findings in the older general population is “extremely useful” for both researchers and clinicians, said study co-author Sarah Elisabeth Keuss, MBChB, clinical research associate, Dementia Research Centre, UCL Queen Square Institute of Neurology, London, UK.

“In research, the knowledge helps to inform study protocols regarding how to manage incidental findings and enables study participants to be appropriately informed,” said Dr. Keuss. Greater awareness also helps clinicians make decisions about whether or not to scan a patient, she said, adding that imaging is increasingly available to them. It allows clinicians to counsel patients regarding the probability of an incidental finding and balance that risk against the potential benefits of having a test.

The research is being presented online as part of the American Academy of Neurology 2020 Science Highlights. The incidental findings also were published last year in BMJ Open.

The new findings are from the first wave of data collection for the Insight 46 study, a neuroimaging substudy of the MRC National Survey of Health and Development (NSHD) 1946 British birth cohort, a broadly representative sample of the population born in mainland Britain during 1946. The research uses detailed brain imaging, cognitive testing, and blood and other biomarkers to investigate genetic and life-course factors associated with Alzheimer’s disease and cerebrovascular disease.

The current study included 502 individuals, aged about 71 years at the time of the analysis, and 49% were women. Almost all (93.8%) participants underwent 1-day MRI scans. Some 4.5% of these participants had an incidental finding of brain abnormality as per a prespecified standardized protocol.

Suspected vascular malformations were present in 1.9%, and suspected intracranial mass lesions were present in 1.5%. The single most common vascular abnormality was a suspected cerebral aneurysm, which affected 1.1% of participants.

Suspected meningiomas were the most common intracranial lesion, affecting 0.6% of study participants.
 

Action plan

Participants and their primary care provider were informed of findings “that were deemed to be potentially serious, or life-threatening, or could have a major impact on quality of life,” said Dr. Keuss. Relevant experts “came up with a recommended clinical action plan to help the primary care provider decide what should be the next course of action with regard to investigation or referral to another specialist,” said Dr. Keuss.

The new results are important for clinical decision-making, said Dr. Keuss. “Clinicians should consider the possibility of detecting an incidental finding whenever they’re requesting a brain scan. They should balance that risk against the possible benefits of recommending a test.”

The prevalence of incidental findings on MRI reported in the literature varies because of different methods used to review scans. “However, comparing our study with similar studies, the prevalence of the key findings with regard to aneurysms and intracranial mass lesions are very similar,” said Dr. Keuss.

Dr. Keuss and colleagues do not recommend all elderly patients get a brain scan.

“We don’t know what the long-term consequences are of being informed you have an incidental finding of an abnormality; we don’t know if it improves their outcome, and it potentially could cause anxiety,” said Dr. Keuss.
 

Psychological impact

The researchers have not looked at the psychological impact of negative findings on study participants, but they could do so at a later date.

“It would be very important to look into that given the potential to cause anxiety,” said Dr. Keuss. “It’s important to find out the potential negative consequences to inform researchers in future about how best to manage these findings.”

From blood tests, the analysis found that more than a third (34.6%) of participants had at least one related abnormality. The most common of these were kidney impairment (about 9%), thyroid function abnormalities (between 4% and 5%), anemia (about 4%), and low vitamin B₁₂ levels (about 3%).

However, few of these reached the prespecified threshold for urgent action, and Dr. Keuss noted these findings were not the focus of her AAN presentation.

A strength of the study was that participants were almost the exact same age.
 

Important issue

Commenting on the research, David S. Liebeskind, MD, professor of neurology and director, Neurovascular Imaging Research Core, University of California, Los Angeles, said it raises “a very interesting” and “important” public health issue.

“The question is whether we do things based around individual symptomatic status, or at a larger level in terms of public health, screening the larger population to figure out who is at risk for any particular disease or disorder.”

From the standpoint of imaging technologies like MRI that show details about brain structures, experts debate whether the population should be screened “before something occurs,” said Dr. Liebeskind. “Imaging has the capacity to tell us a tremendous amount; whether this implies we should therefore image everybody is a larger public health question.”

The issue is “fraught with a lot of difficulty and complexity” as treatment paradigms tend to be “built around symptomatic status,” he said. “When we sit in the office or with a patient at the bedside, we usually focus on that individual patient and not necessarily on the larger public.”

Dr. Liebeskind noted that the question of whether to put the emphasis on the individual patient or the public at large is also being discussed during the current COVID-19 pandemic.

He wasn’t surprised that the study uncovered incidental findings in almost 5% of the sample. “If you take an 80-year-old and study their brain, a good chunk, if not half or more, will have some abnormality,” he said.

Drs. Keuss and Liebeskind have reported no relevant financial relationships.

New research shows that almost 5% of older British citizens have potentially serious brain abnormalities, including aneurysms, and about a third have blood test abnormalities. Knowing the expected prevalence of such incidental findings in the older general population is “extremely useful” for both researchers and clinicians, said study co-author Sarah Elisabeth Keuss, MBChB, clinical research associate, Dementia Research Centre, UCL Queen Square Institute of Neurology, London, UK.

“In research, the knowledge helps to inform study protocols regarding how to manage incidental findings and enables study participants to be appropriately informed,” said Dr. Keuss. Greater awareness also helps clinicians make decisions about whether or not to scan a patient, she said, adding that imaging is increasingly available to them. It allows clinicians to counsel patients regarding the probability of an incidental finding and balance that risk against the potential benefits of having a test.

The research is being presented online as part of the American Academy of Neurology 2020 Science Highlights. The incidental findings also were published last year in BMJ Open.

The new findings are from the first wave of data collection for the Insight 46 study, a neuroimaging substudy of the MRC National Survey of Health and Development (NSHD) 1946 British birth cohort, a broadly representative sample of the population born in mainland Britain during 1946. The research uses detailed brain imaging, cognitive testing, and blood and other biomarkers to investigate genetic and life-course factors associated with Alzheimer’s disease and cerebrovascular disease.

The current study included 502 individuals, aged about 71 years at the time of the analysis, and 49% were women. Almost all (93.8%) participants underwent 1-day MRI scans. Some 4.5% of these participants had an incidental finding of brain abnormality as per a prespecified standardized protocol.

Suspected vascular malformations were present in 1.9%, and suspected intracranial mass lesions were present in 1.5%. The single most common vascular abnormality was a suspected cerebral aneurysm, which affected 1.1% of participants.

Suspected meningiomas were the most common intracranial lesion, affecting 0.6% of study participants.
