Diagnosis at a Glance: Debilitating Thigh Mass in an Obese Patient
Case
A 60-year-old morbidly obese man presented to the ED with a painless mass on his left thigh (Figure 1), which he stated had formed over a several day period 2 months earlier.
On examination, the patient appeared well, with normal vital signs and a body mass index of 56 kg/m2. A computed tomography (CT) scan was obtained to further evaluate the mass (Figure 2), and dermatology services were consulted.
Discussion
Massive localized lymphedema is a complication associated with morbid obesity. First described in 1998 by Farshid and Weiss,1 MLL is characterized by a benign pedunculated mass primarily of the lower extremity that slowly enlarges over years.2 The pathogenesis of MLL is currently unknown. Histologically, MLL contains lobules of mature fat with expanded connective tissue septa without the degree of cellular atypia in well-differentiated liposarcoma (WDL). Though similar to WDL, MLL can be differentiated by the clinical history of a slowly growing mass in a morbidly obese patient and examination findings of overlying reactive skin and soft-tissue changes associated with chronic lymphedema (eg, thickened peau d’orange skin).1,2
The diagnosis of MLL may be made clinically, and if there is no evidence of infection, the patient may be referred to a surgeon. If diagnostic uncertainty remains, biopsy and further CT imaging studies should be considered. The treatment for MLL is a direct excision if the mass is interfering with the patient’s gait. If left untreated, MLL can progress to angiosarcoma. Recurrence is possible, even after surgical excision.3

Failure to Reduce: Small Bowel Obstruction Hidden Within a Chronic Umbilical Hernia Sac
Strangulated hernias are a medical emergency that can lead to small bowel obstruction (SBO), bowel necrosis, and death. Practitioners look for signs of strangulation on examination to guide the urgency of management. If the hernia is soft and reducible without overlying skin changes or signs of obstruction, patients may be monitored for years.1 However, there is increasing evidence that even asymptomatic hernias should be repaired rather than monitored to avoid the need for emergent surgical intervention.1
We present a case of a patient with a chronic umbilical hernia who experienced acute worsening of pain at the site of her hernia but with few additional objective signs of strangulation. Prior to this presentation, she had been recently evaluated at our ED for the “same” pain, which included a computed tomography (CT) scan that was negative for an acute surgical emergency. The patient’s second ED visit led to a diagnostic dilemma: Practitioners are encouraged to avoid “unnecessary” radiation—especially in cases of chronic pain—and to rely on history, physical examination findings, and prior recent imaging studies, as appropriate. In this case, repeat imaging ultimately revealed a surgical emergency with an unusual underlying pathology likely related to the chronicity of the patient’s hernia, and explained her repeat presentation to the ED.
Case
A 45-year-old obese woman (body mass index, 46 kg/m2) with a medical history of an umbilical hernia, tubal ligation, and chronic pelvic pain presented a second time to our ED with pain at the site of her hernia, which she stated began 5 hours prior to presentation. Although the pain was associated with nausea and vomiting, the patient said her bowel movements were normal. She first noticed the hernia more than 5 years ago, but experienced her first episode of acute pain related to the hernia with associated nausea and vomiting 3 weeks earlier, which prompted her initial presentation. During this first ED visit, a CT scan of the abdomen/pelvis was obtained as part of her evaluation and was significant for umbilical herniation of bowel without evidence of strangulation. Bedside reduction was successful, and the patient was discharged home and informed of the need to follow-up with a surgeon for an elective repair. She returned to the ED prior to her scheduled operation due to recurrent pain of similar character, but increased severity.
On physical examination, the patient was hemodynamically stable and afebrile. Her vital signs were: heart rate, 84 beats/min; blood pressure, 113/68 mm Hg; and respiratory rate, 20 breaths/min. Oxygen saturation was 100% on room air.
The abdomen was soft with tenderness to palpation over a 13-cm x 8-cm soft hernia to the left of the umbilicus without overlying skin changes. The patient’s pain was controlled with 1 mg of intravenous hydromorphone, after which bedside reduction was attempted. During reduction attempts, there was palpable bowel within the hernia sac, and a periumbilical defect was appreciated. Although the defect in the abdominal wall was estimated to be large enough to allow reduction, the hernia reduced only partially. Because imaging studies from the patient’s previous ED visit showed no visualized strangulation or obstruction, we deliberated over the need for a repeat CT scan prior to further attempts at reduction by general surgery services. Ultimately, we ordered a repeat CT scan, which was significant for a “mechanical small bowel obstruction with focal transition zone located within the hernia sac itself, not the neck of the umbilical hernia.”
Small bowel obstruction is commonly caused by strangulation at the neck of a hernia. In this case, however, the patient had developed an adhesion within the hernia sac itself, which caused the obstruction. This explains why none of the overlying skin changes commonly found in strangulation were visible, and why we were unable to reduce the bowel even though we could palpate the large abdominal wall defect.
Following evaluation by general surgery services, the patient was admitted for laparoscopic hernia repair. Her case was transitioned to an open repair due to extensive intra-abdominal adhesions. The hernia was closed with mesh, and the patient recovered appropriately postoperatively.
Discussion
Abdominal wall hernias are a common pathology, with more than 700,000 repairs performed every year in the United States.2 Patients most commonly present to the ED with abdominal pain, nausea, and vomiting. Less frequently, they present with obstruction, incarceration, strangulation, or rupture.3 Umbilical hernias are caused by increasing intra-abdominal pressure. As the incidence of obesity in the United States has continued to increase, the proportion of hernias that are umbilical or periumbilical has also increased.2,4 Unfortunately, even though umbilical hernias are becoming more common, they are often given less attention than other types of hernias.5 The practice of solely monitoring umbilical hernias can lead to serious outcomes. For example, in a case presentation from Spain, a morbidly obese patient died due to a strangulated umbilical hernia that had progressed over a 15-year period without treatment.6
Compared to elective surgery, emergent operative repair is associated with a higher rate of postoperative complications,1 and a growing body of evidence suggests that patients with symptomatic hernias should be encouraged to undergo operative repair.1,6
Conclusion
Umbilical hernias have become more common with increasing rates of obesity. These hernias have the potential to lead to serious medical emergencies, and the common practice of monitoring chronic hernias may increase the patient’s risk of serious complications. Emergency physicians use the physical examination to help determine the urgency of repair; however, imaging should be considered to assess hernias that cannot easily be reduced to evaluate for obstructed, strangulated, or incarcerated bowel and to help determine the urgency of surgical repair.

The Burden of COPD
Case Scenario
A 62-year-old man who regularly presented to the ED for exacerbations of chronic obstructive pulmonary disease (COPD) after running out of his medications presented again for evaluation and treatment. His outpatient care had been poorly coordinated, and he relied on the ED to provide him with the support he needed. This presentation represented his fifth visit to the ED over the past 3 months.
The patient’s medical history was positive for asthma since childhood, tobacco use, hypertension, and a recent diagnosis of congestive heart failure (CHF). Over the past year, he had four hospital admissions, and was currently unable to walk from his bedroom to another room without becoming short of breath. He also had recently experienced a 20-lb weight loss.
At this visit, the patient complained of chest pain and lightheadedness, which he described as suffocating. Prior to these recent symptoms, he enjoyed walking in his neighborhood and talking with friends. He was an avid reader and sports fan, but admitted that he now had trouble focusing on reading and following games on television. He lived alone, and his family lived across the country. The patient further admitted that although he had attempted to quit cigarette smoking, he was unable to give up his 50-pack per year habit. He had no completed advance health care directive and had significant challenges tending to his basic needs.
The Trajectory of COPD
Chronic obstructive pulmonary disease is a common chronic illness that causes significant morbidity and mortality. A 2016 National Health Services report cited respiratory illness, primarily from COPD, as the third leading cause of death in the United States in 2014.1The trajectory of this disease is marked by frequent exacerbations with partial recovery to baseline function. The burden of those living with COPD is significant and marked by a poor overall health-related quality of life (QOL). The ED has become a staging area for patients seeking care for exacerbations of COPD.2
The World Health Organization (WHO) and the Global Initiative for Chronic Obstructive Lung Disease (GOLD) have defined COPD as a spectrum of diseases including emphysema, chronic bronchitis, and chronic obstructive asthma characterized by persistent airflow limitation that is usually progressive and associated with an enhanced chronic inflammatory response to noxious particles or gases in the airways and lungs.3 Exacerbations and comorbidities contribute to the overall severity of COPD in individual patients.4
The case presented in this article illustrates the common scenario of a patient whose COPD has become severe and highly symptomatic with declining function to the point where he requires home support. His physical decline had been rapid and resulted in many unmet needs. When a patient such as this presents for emergent care, he must first be stabilized; then a care plan will need to be developed prior to discharge.
Management Goals
The overall goals of treating COPD are based on preserving function and are not curative in nature. Chronic obstructive pulmonary disease is a progressive illness that will intensify over time.5 As such, palliative care services are warranted. However, many patients with COPD do not receive palliative care services compared to patients with such other serious and life-limiting disease as cancer and heart disease.
Acute Exacerbations of COPD
Incidence
The frequency of acute exacerbations of COPD (AECOPD) increases with age, productive cough, long-standing COPD, previous hospitalizations related to COPD, eosinophilia, and comorbidities (eg, CHF). Patients with moderate to severe COPD and a history of prior exacerbations were found to have a higher likelihood of future exacerbations. From a quality and cost perspective, it may be useful to identify high-risk patients and strengthen their outpatient program to lessen the need for ED care and more intensive support.6,7
In our case scenario, the patient could have been stabilized at home with a well-controlled plan and home support, which would have resulted in an improved QOL and more time free from his high symptom burden.
Causes
Bacterial and viral respiratory infections are the most likely cause of AECOPD. Environmental pollution and pulmonary embolism are also triggers. Typically, patients with AECOPD present to the ED up to several times a year2 and represent the third most common cause of 30-day readmissions to the hospital.8 Prior exacerbations, dyspnea, and other medical comorbidities are also risk factors for more frequent hospital visits.
Presenting Signs and Symptoms
Each occurrence of AECOPD represents a worsening of a patient’s respiratory symptoms beyond normal variations. This might include increases in cough, sputum production, and dyspnea. The goal in caring for a person with an AECOPD is to stabilize the acute event and provide a treatment plan. The range of acuity for moderate to severe disease makes devising an appropriate treatment plan challenging, and after implementing the best plans, the patient’s course may be characterized by a prolonged cycle of admissions and readmissions without substantial return to baseline.
Management
In practice, ED management of AECOPD in older adults typically differs significantly from published guideline recommendations,9 which may result in pooroutcomes related to shortcomings in quality of care. Better adherence to guideline recommendations when caring for elderly patients with COPD may lead to improved clinical outcomes and better resource usage.
Risk Stratification
Complicating ED management is the challenge of determining the severity of illness and degree of the exacerbation. Airflow obstruction alone is not sufficient to predict outcomes, as any particular measure of obstruction is associated with a spectrum of forced expiratory volume in the first second (FEV1) and varying performance. Moreover, peak-flow measurements are not useful in the setting of AECOPD, as opposed to their use in acute asthma exacerbations, and are not predictive of changes in clinical status.
GOLD and NICE Criteria
Guidelines have been developed and widely promoted to assist ED and hospital and community clinicians in providing evidence-based management for COPD patients. The GOLD Criteria and the National Institute for Clinical Excellence (NICE) are both clinical guidelines on management of COPD.10
Although well recognized and commonly used, the original GOLD criteria did not take into account the frequency and importance of the extrapulmonary manifestations of COPD in predicting outcome. Typically, those with severe or very severe COPD have an average of 12 co-occurring symptoms, an even greater number of signs and symptoms than those occurring in patients with cancer or heart or renal disease.11
BODE Criteria
The body mass index, airflow obstruction, dyspnea and exercise capacity (BODE) criteria assess and predict the health-related QOL and mortality risk for patients with COPD. Risk is adjusted based on four factors—weight, airway obstruction, dyspnea, and exercise capacity (ie, 6-minute walk distance).13
Initial Evaluation and Work-Up
As previously noted, when an AECOPD patient arrives to the ED, the first priority is to stabilize the patient and initiate treatment. In this respect, initial identification of the patient’s pulse oxygen saturation (SpO2) is important.
Laboratory Evaluation
In cases of respiratory failure, obtaining arterial blood gas (ABG) values are critical. The ABG test will assist in determining acute exacerbations of chronic hypercapnia and the need for ventilatory support. When considering CHF, a plasma B-type natriuretic peptide is useful to assess for CHF.
Imaging Studies
A chest radiograph may be useful in the initial evaluation to identify abnormalities, including barotrauma (ie, pneumothorax) and infiltrates. Additionally, in patients with comorbidities, it is important to assess cardiac status, and a chest X-ray may assist in identification of pulmonary edema, pleural effusions, and cardiomegaly. If the radiograph does show a pulmonary infiltrate (ie, pneumonia), it will help identify the probable triggers, but even in these instances, a sputum gram stain will not assist in the diagnosis.
Treatment
Relieving airflow obstruction is achieved with inhaled short-acting bronchodilators and systemic glucocorticoids, by treating infection, and by providing supplemental oxygen and ventilatory support.
Bronchodilators
The short-acting beta-adrenergic agonists (eg, albuterol) act rapidly and are effective in producing bronchodilation. Nebulized therapy may be most comfortable for the acutely ill patient. Typical dosing is 2.5 mg albuterol diluted to 3 cc by nebulizer every hour. Higher doses are not more effective, and there is no evidence of a higher response rate from constant nebulized therapy, which can cause anxiety and tachycardia in patients.14 Anticholinergic agents (eg, ipratropium) are often added despite unclear data regarding clinical advantage. In one study evaluating the effectiveness of adding ipratropium to albuterol, patients receiving a combination had the same improvement in FEV1 at 90 minutes.15 Patients receiving ipratropium alone had the lowest rate of reported side effects.15
Systemic Glucocorticoids
Short-course systemic glucocorticoids are an important addition to treatment and have been found to improve spirometry and decrease relapse rate. The oral and intravenous (IV) routes provide the same benefit. For the acutely ill patient with challenges swallowing, the IV route is preferred. The optimal dose is not clear, but hydrocortisone doses of 100 mg to 125 mg every 6 hours for 3 days are effective, as is oral prednisone 30 mg per day for 14 days, or 60 mg per day for 3 days with a taper.
Antibiotic Therapy
Antibiotics are indicated for patients with moderate to severe AECOPD who are ill enough to be admitted to the hospital. Empiric broad spectrum treatment is recommended. The initial antibiotic regimen should target likely bacterial pathogens (Haemophilus influenzae, Moraxella catarrhalis, and Streptococcus pneumoniae in most patients) and take into account local patterns of antibiotic resistance. Flouroquinolones or third-generation cephalosporins generally provide sufficient coverage. For patients experiencing only a mild exacerbation, antibiotics are not warranted.
Magnesium Sulfate
Other supplemental medications that have been evaluated include magnesium sulfate for bronchial smooth muscle relaxation. Studies have found that while magnesium is helpful in asthma, results are mixed with COPD.16
Supplemental Oxygen
Oxygen therapy is important during an AECOPD episode. Often, concerns arise about decreasing respiratory drive, which is typically driven by hypoxia in patients who have chronic hypercapnia. Arterial blood gas determinations are important in managing a patient’s respiratory status and will assist in determining actual oxygenation and any coexistent metabolic disturbances.
Noninvasive Ventilation. Oxygen can be administered efficiently by a venturi mask, which delivers precise fractions of oxygen, or by nasal cannula. A facemask is less comfortable, but is available for higher oxygen requirements, providing up to 55% oxygen, while a nonrebreather mask delivers up to 90% oxygen.
When necessary, noninvasive positive pressure ventilation (NPPV) improves outcomes for those with severe dyspnea and signs of respiratory fatigue manifested as increased work of breathing. Noninvasive positive pressure ventilation can improve clinical outcomes and is the ventilator mode of choice for those patients with COPD. Indications include severe dyspnea with signs of increased work of breathing and respiratory acidosis (arterial pH <7.35) and partial pressure of arterial carbon dioxide (PaCO2) >45 mm Hg.
Whenever possible, NPPV should be initiated with a triggered mode to allow spontaneous breaths. Inspiratory pressure of 8 cm to 12 cm H2O and expiratory pressure of 3 cm to 5 cm of H2 are recommended.
Mechanical Ventilation. Mechanical ventilation is often undesirable because it may be extraordinarily difficult to wean a patient off the device and permit safe extubation. However, if a patient cannot be stabilized with NPPV, intubation and mechanical ventilation must be considered. Typically, this occurs when there is severe respiratory distress, tachypnea >30 breaths/min, accessory muscle use, and altered mentation.
Goals of intubation/mechanical respiration include correcting oxygenation and severe respiratory acidosis as well as reducing the work of breathing. Barotrauma is a significant risk when patients with COPD require mechanical ventilation. Volume-limited modes of ventilation are commonly used, while pressure support or pressure-limited modes are less suitable for patients with airflow limitation. Again, invasive ventilation should only be administered if a patient cannot tolerate NPPV.
Palliative Care in the ED
Palliative care is an approach that improves the QOL of patients and their families facing the issues associated with life-threatening illness, through the prevention and relief of suffering by means of early identification and accurate assessment and treatment of pain and physical, psychosocial, and spiritual problems.3 This approach to care is warranted for COPD patients given the myriad of burdensome symptoms and functional decline that occurs.17
Palliative care expands traditional treatment goals to include enhancing QOL; helping with medical decision making; and identifying the goals of care. Palliative care is provided by board-certified physicians for the most complex of cases. However, the primary practice of palliative care must be delivered at the bedside by the treating provider. Managing pain, dyspnea, nausea, vomiting, and changes in bowel habits, as well as discussing goals of care, are among the basic palliative care skills all providers need to have and apply when indicated.
Palliative Care for Dyspnea
Opioids. Primary palliative care in the ED includes the appropriate use of low-dose oral and parenteral opioids to treat dyspnea in AECOPD. The use of a low-dose opioid, such as morphine 2 mg IV, titrated up to a desired response, is a safe and effective practice.18 Note the 2-mg starting dose is considered low-dose.19
With respect to managing dyspnea in AECOPD patients, nebulized opioids have not been found to be better than nebulized saline. More specific data regarding the use of oral opioids for managing refractory dyspnea in patients with predominantly COPD have been recently published: Long-acting morphine 20 mg once daily provides symptomatic relief in refractory dyspnea in the community setting. For the opioid-naïve patient, a lower dose is recommended.20
Oxygenation. There is no hard evidence of the effectiveness of oxygen in the palliation of breathlessness. Humidified air is effective initially, as is providing a fan at the bedside. Short-burst oxygen therapy should only be considered for episodes of severe breathlessness in patients whose COPD is not relieved by other treatments. Oxygen should continue to be prescribed only if an improvement in breathlessness following therapy has been documented. The American Thoracic Society recommends continuous oxygen therapy in patients with COPD who have severe resting hypoxemia (PaCO2 ≤55 mm Hg or SpO2 ≤88%).21
POLST Form
The Physicians Order for Life-Sustaining Treatment (POLST) form is a set of medical orders, similar to the “do not resuscitate” (allow natural death) order. A POLST form is not an advance directive and does not serve as a substitute for a patient’s assignation of a health care agent or durable power of attorney for health care.22
The POLST form enables physicians to order treatments patients would want, identify those treatments that patients would not want, and not provide those the patient considers “extraordinary” and excessively burdensome. A POLST form does not allow for active euthanasia or physician-assisted suicide.
Identifying treatment preferences is an important part of the initial evaluation of all patients. When dealing with an airway issue in a COPD patient, management can become complex. Ideally, the POLST form should arrive with the patient in the ED and list preferences regarding possible intensive interventions such as intubation and chest compressions. Discussing these issues with a patient in extreme distress is difficult or impossible, and in these cases, access to pertinent medical records, discussing preferences with family caregivers, and availability of a POLST form are much better ways to determine therapy.
Palliative Home Care
Patient Safety Considerations
Weight loss and associated muscle wasting are common features in patients with severe COPD, creating a high-risk situation for falls and a need for assistance with activities of daily living. The patient who is frail when discharged home from the ED requires a home-care plan before leaving the ED, and strict follow-up with the patient’s primary care provider will typically be needed within 2 to 4 weeks.
Psychological Considerations
Being mindful of the anxiety and depression that accompany the physical limitations of those with COPD is important. Mood disturbances serve as risk factors for re-hospitalization and mortality.13Multiple palliative care interventions provide patients assistance with these issues, including the use of antidepressants that may aid sleep, stabilize mood, and stimulate appetite.
Early referral to the palliative care team will provide improved care for the patient and family. Palliative care referral will provide continued management of the physical symptoms and evaluation and treatment of the psychosocial issues that accompany COPD. Additionally, the palliative care team can assist with safe discharge planning and follow-up, including the provision of the patient’s home needs as well as the family’s ability to cope with the home setting.
Prognosis
Predicting prognosis is difficult for the COPD patient due to the highly variable illness trajectory. Some patients have a low FEV1 and yet are very functional. However, assessment of severity of lung function impairment, frequency of exacerbations, and need for long-term oxygen therapy helps identify those patients who are entering the final 12 months of life. Evaluating symptom burden and impact on activities of daily living for patients with COPD is comparable to those of cancer patients, and in both cases, palliative care approaches are necessary.
Predicting Morbidity and Mortality
A profile developed from observational studies can help predict 6- to 12-month morbidity and mortality in patients with advanced COPD. This profile includes the following criteria:
- Significant dyspnea;
- FEV1 <30%;
- Number of exacerbations;
- Left heart failure or other comorbidities;
- Weight loss or cachexia;
- Decreasing performance status;
- Age older than 70 years; and
- Depression.
Although additional research is required to refine and verify this profile, reviewing these data points can prompt providers to initiate discussions with patients about treatment preferences and end-of-life care.23,24
Palliative Performance Scale
The Palliative Performance Scale (PPS) is another scale used to predict prognosis and eligibility for hospice care.25 This score provides a patient’s estimated survival.25 For a patient with a PPS score of 50%, hospice education may be appropriate.
Case Scenario Continued
Both the BODE and GOLD criteria scores assisted in determining prognosis and risk profiles of the patient in our case scenario. By applying the BODE criteria, our patient had a 4-year survival benefit of under 18%. The GOLD criteria results for this patient also were consistent with the BODE criteria and reflected end-stage COPD. Since this patient also had a PPS score of 50%, hospice education and care were discussed and initiated.
Conclusion
Patients with AECOPD commonly present to the ED. Such patients suffer with a high burden of illness and a need for immediate symptom management. However, after these measures have been instituted, strong evidence suggests that these patients typically do not receive palliative care with the same frequency compared to cancer or heart disease patients.
Management of AECOPD in the ED must include rapid treatment of dyspnea and pain, but also a determination of treatment preferences and an understanding of the prognosis. Several criteria are available to guide prognostic awareness and may help further the goals of care and disposition. Primary palliative care should be started by the ED provider for appropriate patients, with early referral to the palliative care team.

Case Scenario
A 62-year-old man who regularly presented to the ED for exacerbations of chronic obstructive pulmonary disease (COPD) after running out of his medications presented again for evaluation and treatment. His outpatient care had been poorly coordinated, and he relied on the ED to provide him with the support he needed. This presentation represented his fifth visit to the ED over the past 3 months.
The patient’s medical history was positive for asthma since childhood, tobacco use, hypertension, and a recent diagnosis of congestive heart failure (CHF). Over the past year, he had four hospital admissions, and was currently unable to walk from his bedroom to another room without becoming short of breath. He also had recently experienced a 20-lb weight loss.
At this visit, the patient complained of chest pain and lightheadedness, which he described as suffocating. Prior to these recent symptoms, he enjoyed walking in his neighborhood and talking with friends. He was an avid reader and sports fan, but admitted that he now had trouble focusing on reading and following games on television. He lived alone, and his family lived across the country. The patient further admitted that although he had attempted to quit cigarette smoking, he was unable to give up his 50-pack per year habit. He had no completed advance health care directive and had significant challenges tending to his basic needs.
The Trajectory of COPD
Chronic obstructive pulmonary disease is a common chronic illness that causes significant morbidity and mortality. A 2016 National Health Services report cited respiratory illness, primarily from COPD, as the third leading cause of death in the United States in 2014.1The trajectory of this disease is marked by frequent exacerbations with partial recovery to baseline function. The burden of those living with COPD is significant and marked by a poor overall health-related quality of life (QOL). The ED has become a staging area for patients seeking care for exacerbations of COPD.2
The World Health Organization (WHO) and the Global Initiative for Chronic Obstructive Lung Disease (GOLD) have defined COPD as a spectrum of diseases including emphysema, chronic bronchitis, and chronic obstructive asthma characterized by persistent airflow limitation that is usually progressive and associated with an enhanced chronic inflammatory response to noxious particles or gases in the airways and lungs.3 Exacerbations and comorbidities contribute to the overall severity of COPD in individual patients.4
The case presented in this article illustrates the common scenario of a patient whose COPD has become severe and highly symptomatic with declining function to the point where he requires home support. His physical decline had been rapid and resulted in many unmet needs. When a patient such as this presents for emergent care, he must first be stabilized; then a care plan will need to be developed prior to discharge.
Management Goals
The overall goals of treating COPD are based on preserving function and are not curative in nature. Chronic obstructive pulmonary disease is a progressive illness that will intensify over time.5 As such, palliative care services are warranted. However, many patients with COPD do not receive palliative care services compared to patients with such other serious and life-limiting disease as cancer and heart disease.
Acute Exacerbations of COPD
Incidence
The frequency of acute exacerbations of COPD (AECOPD) increases with age, productive cough, long-standing COPD, previous hospitalizations related to COPD, eosinophilia, and comorbidities (eg, CHF). Patients with moderate to severe COPD and a history of prior exacerbations were found to have a higher likelihood of future exacerbations. From a quality and cost perspective, it may be useful to identify high-risk patients and strengthen their outpatient program to lessen the need for ED care and more intensive support.6,7
In our case scenario, the patient could have been stabilized at home with a well-controlled plan and home support, which would have resulted in an improved QOL and more time free from his high symptom burden.
Causes
Bacterial and viral respiratory infections are the most likely cause of AECOPD. Environmental pollution and pulmonary embolism are also triggers. Typically, patients with AECOPD present to the ED up to several times a year2 and represent the third most common cause of 30-day readmissions to the hospital.8 Prior exacerbations, dyspnea, and other medical comorbidities are also risk factors for more frequent hospital visits.
Presenting Signs and Symptoms
Each occurrence of AECOPD represents a worsening of a patient’s respiratory symptoms beyond normal variations. This might include increases in cough, sputum production, and dyspnea. The goal in caring for a person with an AECOPD is to stabilize the acute event and provide a treatment plan. The range of acuity for moderate to severe disease makes devising an appropriate treatment plan challenging, and after implementing the best plans, the patient’s course may be characterized by a prolonged cycle of admissions and readmissions without substantial return to baseline.
Management
In practice, ED management of AECOPD in older adults typically differs significantly from published guideline recommendations,9 which may result in pooroutcomes related to shortcomings in quality of care. Better adherence to guideline recommendations when caring for elderly patients with COPD may lead to improved clinical outcomes and better resource usage.
Risk Stratification
Complicating ED management is the challenge of determining the severity of illness and degree of the exacerbation. Airflow obstruction alone is not sufficient to predict outcomes, as any particular measure of obstruction is associated with a spectrum of forced expiratory volume in the first second (FEV1) and varying performance. Moreover, peak-flow measurements are not useful in the setting of AECOPD, as opposed to their use in acute asthma exacerbations, and are not predictive of changes in clinical status.
GOLD and NICE Criteria
Guidelines have been developed and widely promoted to assist ED and hospital and community clinicians in providing evidence-based management for COPD patients. The GOLD Criteria and the National Institute for Clinical Excellence (NICE) are both clinical guidelines on management of COPD.10
Although well recognized and commonly used, the original GOLD criteria did not take into account the frequency and importance of the extrapulmonary manifestations of COPD in predicting outcome. Typically, those with severe or very severe COPD have an average of 12 co-occurring symptoms, an even greater number of signs and symptoms than those occurring in patients with cancer or heart or renal disease.11
BODE Criteria
The body mass index, airflow obstruction, dyspnea and exercise capacity (BODE) criteria assess and predict the health-related QOL and mortality risk for patients with COPD. Risk is adjusted based on four factors—weight, airway obstruction, dyspnea, and exercise capacity (ie, 6-minute walk distance).13

Psychological Considerations
Being mindful of the anxiety and depression that accompany the physical limitations of those with COPD is important. Mood disturbances serve as risk factors for re-hospitalization and mortality.13Multiple palliative care interventions provide patients assistance with these issues, including the use of antidepressants that may aid sleep, stabilize mood, and stimulate appetite.
Early referral to the palliative care team will provide improved care for the patient and family. Palliative care referral will provide continued management of the physical symptoms and evaluation and treatment of the psychosocial issues that accompany COPD. Additionally, the palliative care team can assist with safe discharge planning and follow-up, including the provision of the patient’s home needs as well as the family’s ability to cope with the home setting.
Prognosis
Predicting prognosis is difficult for the COPD patient due to the highly variable illness trajectory. Some patients have a low FEV1 and yet are very functional. However, assessment of severity of lung function impairment, frequency of exacerbations, and need for long-term oxygen therapy helps identify those patients who are entering the final 12 months of life. Evaluating symptom burden and impact on activities of daily living for patients with COPD is comparable to those of cancer patients, and in both cases, palliative care approaches are necessary.
Predicting Morbidity and Mortality
A profile developed from observational studies can help predict 6- to 12-month morbidity and mortality in patients with advanced COPD. This profile includes the following criteria:
- Significant dyspnea;
- FEV1 <30%;
- Number of exacerbations;
- Left heart failure or other comorbidities;
- Weight loss or cachexia;
- Decreasing performance status;
- Age older than 70 years; and
- Depression.
Although additional research is required to refine and verify this profile, reviewing these data points can prompt providers to initiate discussions with patients about treatment preferences and end-of-life care.23,24
Palliative Performance Scale
The Palliative Performance Scale (PPS) is another scale used to predict prognosis and eligibility for hospice care.25 This score provides a patient’s estimated survival.25 For a patient with a PPS score of 50%, hospice education may be appropriate.
Case Scenario Continued
Both the BODE and GOLD criteria scores assisted in determining prognosis and risk profiles of the patient in our case scenario. By applying the BODE criteria, our patient had a 4-year survival benefit of under 18%. The GOLD criteria results for this patient also were consistent with the BODE criteria and reflected end-stage COPD. Since this patient also had a PPS score of 50%, hospice education and care were discussed and initiated.
Conclusion
Patients with AECOPD commonly present to the ED. Such patients suffer with a high burden of illness and a need for immediate symptom management. However, after these measures have been instituted, strong evidence suggests that these patients typically do not receive palliative care with the same frequency compared to cancer or heart disease patients.
Management of AECOPD in the ED must include rapid treatment of dyspnea and pain, but also a determination of treatment preferences and an understanding of the prognosis. Several criteria are available to guide prognostic awareness and may help further the goals of care and disposition. Primary palliative care should be started by the ED provider for appropriate patients, with early referral to the palliative care team.
Case Scenario
A 62-year-old man who regularly presented to the ED for exacerbations of chronic obstructive pulmonary disease (COPD) after running out of his medications presented again for evaluation and treatment. His outpatient care had been poorly coordinated, and he relied on the ED to provide him with the support he needed. This presentation represented his fifth visit to the ED over the past 3 months.
The patient’s medical history was positive for asthma since childhood, tobacco use, hypertension, and a recent diagnosis of congestive heart failure (CHF). Over the past year, he had four hospital admissions, and was currently unable to walk from his bedroom to another room without becoming short of breath. He also had recently experienced a 20-lb weight loss.
At this visit, the patient complained of chest pain and lightheadedness, which he described as suffocating. Prior to these recent symptoms, he enjoyed walking in his neighborhood and talking with friends. He was an avid reader and sports fan, but admitted that he now had trouble focusing on reading and following games on television. He lived alone, and his family lived across the country. The patient further admitted that although he had attempted to quit cigarette smoking, he was unable to give up his 50-pack per year habit. He had no completed advance health care directive and had significant challenges tending to his basic needs.
The Trajectory of COPD
Chronic obstructive pulmonary disease is a common chronic illness that causes significant morbidity and mortality. A 2016 National Health Services report cited respiratory illness, primarily from COPD, as the third leading cause of death in the United States in 2014.1The trajectory of this disease is marked by frequent exacerbations with partial recovery to baseline function. The burden of those living with COPD is significant and marked by a poor overall health-related quality of life (QOL). The ED has become a staging area for patients seeking care for exacerbations of COPD.2
The World Health Organization (WHO) and the Global Initiative for Chronic Obstructive Lung Disease (GOLD) have defined COPD as a spectrum of diseases including emphysema, chronic bronchitis, and chronic obstructive asthma characterized by persistent airflow limitation that is usually progressive and associated with an enhanced chronic inflammatory response to noxious particles or gases in the airways and lungs.3 Exacerbations and comorbidities contribute to the overall severity of COPD in individual patients.4
The case presented in this article illustrates the common scenario of a patient whose COPD has become severe and highly symptomatic with declining function to the point where he requires home support. His physical decline had been rapid and resulted in many unmet needs. When a patient such as this presents for emergent care, he must first be stabilized; then a care plan will need to be developed prior to discharge.
Management Goals
The overall goals of treating COPD are based on preserving function and are not curative in nature. Chronic obstructive pulmonary disease is a progressive illness that will intensify over time.5 As such, palliative care services are warranted. However, many patients with COPD do not receive palliative care services compared to patients with such other serious and life-limiting disease as cancer and heart disease.
Acute Exacerbations of COPD
Incidence
The frequency of acute exacerbations of COPD (AECOPD) increases with age, productive cough, long-standing COPD, previous hospitalizations related to COPD, eosinophilia, and comorbidities (eg, CHF). Patients with moderate to severe COPD and a history of prior exacerbations were found to have a higher likelihood of future exacerbations. From a quality and cost perspective, it may be useful to identify high-risk patients and strengthen their outpatient program to lessen the need for ED care and more intensive support.6,7
In our case scenario, the patient could have been stabilized at home with a well-controlled plan and home support, which would have resulted in an improved QOL and more time free from his high symptom burden.
Causes
Bacterial and viral respiratory infections are the most likely cause of AECOPD. Environmental pollution and pulmonary embolism are also triggers. Typically, patients with AECOPD present to the ED up to several times a year2 and represent the third most common cause of 30-day readmissions to the hospital.8 Prior exacerbations, dyspnea, and other medical comorbidities are also risk factors for more frequent hospital visits.
Presenting Signs and Symptoms
Each occurrence of AECOPD represents a worsening of a patient’s respiratory symptoms beyond normal variations. This might include increases in cough, sputum production, and dyspnea. The goal in caring for a person with an AECOPD is to stabilize the acute event and provide a treatment plan. The range of acuity for moderate to severe disease makes devising an appropriate treatment plan challenging, and after implementing the best plans, the patient’s course may be characterized by a prolonged cycle of admissions and readmissions without substantial return to baseline.
Management
In practice, ED management of AECOPD in older adults typically differs significantly from published guideline recommendations,9 which may result in pooroutcomes related to shortcomings in quality of care. Better adherence to guideline recommendations when caring for elderly patients with COPD may lead to improved clinical outcomes and better resource usage.
Risk Stratification
Complicating ED management is the challenge of determining the severity of illness and degree of the exacerbation. Airflow obstruction alone is not sufficient to predict outcomes, as any particular measure of obstruction is associated with a spectrum of forced expiratory volume in the first second (FEV1) and varying performance. Moreover, peak-flow measurements are not useful in the setting of AECOPD, as opposed to their use in acute asthma exacerbations, and are not predictive of changes in clinical status.
GOLD and NICE Criteria
Guidelines have been developed and widely promoted to assist ED and hospital and community clinicians in providing evidence-based management for COPD patients. The GOLD Criteria and the National Institute for Clinical Excellence (NICE) are both clinical guidelines on management of COPD.10
Although well recognized and commonly used, the original GOLD criteria did not take into account the frequency and importance of the extrapulmonary manifestations of COPD in predicting outcome. Typically, those with severe or very severe COPD have an average of 12 co-occurring symptoms, an even greater number of signs and symptoms than those occurring in patients with cancer or heart or renal disease.11
BODE Criteria
The body mass index, airflow obstruction, dyspnea and exercise capacity (BODE) criteria assess and predict the health-related QOL and mortality risk for patients with COPD. Risk is adjusted based on four factors—weight, airway obstruction, dyspnea, and exercise capacity (ie, 6-minute walk distance).13
Initial Evaluation and Work-Up
As previously noted, when an AECOPD patient arrives to the ED, the first priority is to stabilize the patient and initiate treatment. In this respect, initial identification of the patient’s pulse oxygen saturation (SpO2) is important.
Laboratory Evaluation
In cases of respiratory failure, obtaining arterial blood gas (ABG) values are critical. The ABG test will assist in determining acute exacerbations of chronic hypercapnia and the need for ventilatory support. When considering CHF, a plasma B-type natriuretic peptide is useful to assess for CHF.
Imaging Studies
A chest radiograph may be useful in the initial evaluation to identify abnormalities, including barotrauma (ie, pneumothorax) and infiltrates. Additionally, in patients with comorbidities, it is important to assess cardiac status, and a chest X-ray may assist in identification of pulmonary edema, pleural effusions, and cardiomegaly. If the radiograph does show a pulmonary infiltrate (ie, pneumonia), it will help identify the probable triggers, but even in these instances, a sputum gram stain will not assist in the diagnosis.
Treatment
Relieving airflow obstruction is achieved with inhaled short-acting bronchodilators and systemic glucocorticoids, by treating infection, and by providing supplemental oxygen and ventilatory support.
Bronchodilators
The short-acting beta-adrenergic agonists (eg, albuterol) act rapidly and are effective in producing bronchodilation. Nebulized therapy may be most comfortable for the acutely ill patient. Typical dosing is 2.5 mg albuterol diluted to 3 cc by nebulizer every hour. Higher doses are not more effective, and there is no evidence of a higher response rate from constant nebulized therapy, which can cause anxiety and tachycardia in patients.14 Anticholinergic agents (eg, ipratropium) are often added despite unclear data regarding clinical advantage. In one study evaluating the effectiveness of adding ipratropium to albuterol, patients receiving a combination had the same improvement in FEV1 at 90 minutes.15 Patients receiving ipratropium alone had the lowest rate of reported side effects.15
Systemic Glucocorticoids
Short-course systemic glucocorticoids are an important addition to treatment and have been found to improve spirometry and decrease relapse rate. The oral and intravenous (IV) routes provide the same benefit. For the acutely ill patient with challenges swallowing, the IV route is preferred. The optimal dose is not clear, but hydrocortisone doses of 100 mg to 125 mg every 6 hours for 3 days are effective, as is oral prednisone 30 mg per day for 14 days, or 60 mg per day for 3 days with a taper.
Antibiotic Therapy
Antibiotics are indicated for patients with moderate to severe AECOPD who are ill enough to be admitted to the hospital. Empiric broad spectrum treatment is recommended. The initial antibiotic regimen should target likely bacterial pathogens (Haemophilus influenzae, Moraxella catarrhalis, and Streptococcus pneumoniae in most patients) and take into account local patterns of antibiotic resistance. Flouroquinolones or third-generation cephalosporins generally provide sufficient coverage. For patients experiencing only a mild exacerbation, antibiotics are not warranted.
Magnesium Sulfate
Other supplemental medications that have been evaluated include magnesium sulfate for bronchial smooth muscle relaxation. Studies have found that while magnesium is helpful in asthma, results are mixed with COPD.16
Supplemental Oxygen
Oxygen therapy is important during an AECOPD episode. Often, concerns arise about decreasing respiratory drive, which is typically driven by hypoxia in patients who have chronic hypercapnia. Arterial blood gas determinations are important in managing a patient’s respiratory status and will assist in determining actual oxygenation and any coexistent metabolic disturbances.
Noninvasive Ventilation. Oxygen can be administered efficiently by a venturi mask, which delivers precise fractions of oxygen, or by nasal cannula. A facemask is less comfortable, but is available for higher oxygen requirements, providing up to 55% oxygen, while a nonrebreather mask delivers up to 90% oxygen.
When necessary, noninvasive positive pressure ventilation (NPPV) improves outcomes for those with severe dyspnea and signs of respiratory fatigue manifested as increased work of breathing. Noninvasive positive pressure ventilation can improve clinical outcomes and is the ventilator mode of choice for those patients with COPD. Indications include severe dyspnea with signs of increased work of breathing and respiratory acidosis (arterial pH <7.35) and partial pressure of arterial carbon dioxide (PaCO2) >45 mm Hg.
Whenever possible, NPPV should be initiated with a triggered mode to allow spontaneous breaths. Inspiratory pressure of 8 cm to 12 cm H2O and expiratory pressure of 3 cm to 5 cm of H2 are recommended.
Mechanical Ventilation. Mechanical ventilation is often undesirable because it may be extraordinarily difficult to wean a patient off the device and permit safe extubation. However, if a patient cannot be stabilized with NPPV, intubation and mechanical ventilation must be considered. Typically, this occurs when there is severe respiratory distress, tachypnea >30 breaths/min, accessory muscle use, and altered mentation.
Goals of intubation/mechanical respiration include correcting oxygenation and severe respiratory acidosis as well as reducing the work of breathing. Barotrauma is a significant risk when patients with COPD require mechanical ventilation. Volume-limited modes of ventilation are commonly used, while pressure support or pressure-limited modes are less suitable for patients with airflow limitation. Again, invasive ventilation should only be administered if a patient cannot tolerate NPPV.
Palliative Care in the ED
Palliative care is an approach that improves the QOL of patients and their families facing the issues associated with life-threatening illness, through the prevention and relief of suffering by means of early identification and accurate assessment and treatment of pain and physical, psychosocial, and spiritual problems.3 This approach to care is warranted for COPD patients given the myriad of burdensome symptoms and functional decline that occurs.17
Palliative care expands traditional treatment goals to include enhancing QOL; helping with medical decision making; and identifying the goals of care. Palliative care is provided by board-certified physicians for the most complex of cases. However, the primary practice of palliative care must be delivered at the bedside by the treating provider. Managing pain, dyspnea, nausea, vomiting, and changes in bowel habits, as well as discussing goals of care, are among the basic palliative care skills all providers need to have and apply when indicated.
Palliative Care for Dyspnea
Opioids. Primary palliative care in the ED includes the appropriate use of low-dose oral and parenteral opioids to treat dyspnea in AECOPD. The use of a low-dose opioid, such as morphine 2 mg IV, titrated up to a desired response, is a safe and effective practice.18 Note the 2-mg starting dose is considered low-dose.19
With respect to managing dyspnea in AECOPD patients, nebulized opioids have not been found to be better than nebulized saline. More specific data regarding the use of oral opioids for managing refractory dyspnea in patients with predominantly COPD have been recently published: Long-acting morphine 20 mg once daily provides symptomatic relief in refractory dyspnea in the community setting. For the opioid-naïve patient, a lower dose is recommended.20
Oxygenation. There is no hard evidence of the effectiveness of oxygen in the palliation of breathlessness. Humidified air is effective initially, as is providing a fan at the bedside. Short-burst oxygen therapy should only be considered for episodes of severe breathlessness in patients whose COPD is not relieved by other treatments. Oxygen should continue to be prescribed only if an improvement in breathlessness following therapy has been documented. The American Thoracic Society recommends continuous oxygen therapy in patients with COPD who have severe resting hypoxemia (PaCO2 ≤55 mm Hg or SpO2 ≤88%).21
POLST Form
The Physicians Order for Life-Sustaining Treatment (POLST) form is a set of medical orders, similar to the “do not resuscitate” (allow natural death) order. A POLST form is not an advance directive and does not serve as a substitute for a patient’s assignation of a health care agent or durable power of attorney for health care.22
The POLST form enables physicians to order treatments patients would want, identify those treatments that patients would not want, and not provide those the patient considers “extraordinary” and excessively burdensome. A POLST form does not allow for active euthanasia or physician-assisted suicide.
Identifying treatment preferences is an important part of the initial evaluation of all patients. When dealing with an airway issue in a COPD patient, management can become complex. Ideally, the POLST form should arrive with the patient in the ED and list preferences regarding possible intensive interventions such as intubation and chest compressions. Discussing these issues with a patient in extreme distress is difficult or impossible, and in these cases, access to pertinent medical records, discussing preferences with family caregivers, and availability of a POLST form are much better ways to determine therapy.
Palliative Home Care
Patient Safety Considerations
Weight loss and associated muscle wasting are common features in patients with severe COPD, creating a high-risk situation for falls and a need for assistance with activities of daily living. The patient who is frail when discharged home from the ED requires a home-care plan before leaving the ED, and strict follow-up with the patient’s primary care provider will typically be needed within 2 to 4 weeks.
Psychological Considerations
Being mindful of the anxiety and depression that accompany the physical limitations of those with COPD is important. Mood disturbances serve as risk factors for re-hospitalization and mortality.13Multiple palliative care interventions provide patients assistance with these issues, including the use of antidepressants that may aid sleep, stabilize mood, and stimulate appetite.
Early referral to the palliative care team will provide improved care for the patient and family. Palliative care referral will provide continued management of the physical symptoms and evaluation and treatment of the psychosocial issues that accompany COPD. Additionally, the palliative care team can assist with safe discharge planning and follow-up, including the provision of the patient’s home needs as well as the family’s ability to cope with the home setting.
Prognosis
Predicting prognosis is difficult for the COPD patient due to the highly variable illness trajectory. Some patients have a low FEV1 and yet are very functional. However, assessment of severity of lung function impairment, frequency of exacerbations, and need for long-term oxygen therapy helps identify those patients who are entering the final 12 months of life. Evaluating symptom burden and impact on activities of daily living for patients with COPD is comparable to those of cancer patients, and in both cases, palliative care approaches are necessary.
Predicting Morbidity and Mortality
A profile developed from observational studies can help predict 6- to 12-month morbidity and mortality in patients with advanced COPD. This profile includes the following criteria:
- Significant dyspnea;
- FEV1 <30%;
- Number of exacerbations;
- Left heart failure or other comorbidities;
- Weight loss or cachexia;
- Decreasing performance status;
- Age older than 70 years; and
- Depression.
Although additional research is required to refine and verify this profile, reviewing these data points can prompt providers to initiate discussions with patients about treatment preferences and end-of-life care.23,24
Palliative Performance Scale
The Palliative Performance Scale (PPS) is another scale used to predict prognosis and eligibility for hospice care.25 This score provides a patient’s estimated survival.25 For a patient with a PPS score of 50%, hospice education may be appropriate.

Case Studies in Toxicology: Somehow…It’s Always Lupus
Case
A 14-year-old girl with no known medical history presented to the ED via emergency medical services (EMS) approximately 1.5 hours after intentionally ingesting what she described as “a handful or two” of her mother’s lupus prescription medication in a suicide attempt. Initial vital signs and physical examination were normal, and her only complaint was nausea.
Thirty minutes after presentation, the patient suffered acute cardiovascular (CV) collapse: blood pressure, 57/39 mm Hg; heart rate, 90 beats/min. An initial electrocardiogram (ECG) revealed QRS duration of 123 milliseconds and QTc duration of 510 milliseconds, along with nonspecific T-wave abnormalities. A 150-mEq intravenous (IV) bolus of sodium bicarbonate and a 40-mEq potassium chloride IV infusion were administered, and both epinephrine and norepinephrine IV infusions were also initiated. A basic metabolic panel obtained prior to medication administration showed a potassium concentration of 1.9 mmol/L.
What is the differential diagnosis of toxicological hypokalemia?
Hypokalemia may be reflective of diminished whole body potassium stores or a transient alteration of intravascular potassium concentrations. In acute ingestions and overdose, the etiology of the hypokalemia is often electrolyte redistribution through either blockade of constitutive outward potassium leakage (eg, barium, insulin, quinine) or through increased activity of the Na+/K+-ATPase pump (eg, catecholamines, insulin, methylxanthines). This activity has little effect on whole body potassium stores, but can result in a profound fall in the serum potassium. While mild hypokalemia is generally well tolerated, more severe potassium abnormalities can cause muscular weakness, areflexic paralysis, respiratory failure, and life-threatening dysrhythmias. Common ECG findings include decreased T-wave amplitudes, ST-segment depression, and the presence or amplification of U waves.
Case Continuation
While the emergency physicians were stabilizing the patient, her mother provided additional information. Approximately 30 minutes after the exposure, the patient had become nauseated and told her mother what she had done. Her mother called EMS, and the patient was transported to the hospital, where she rapidly became symptomatic. Despite CV decompensation, she remained neurologically intact. On further questioning, the patient admitted to ingesting 6 g of her mother’s prescription of hydroxychloroquine (HCQ) in a suicide attempt but denied taking any other medications. She was stabilized on vasopressors and admitted to the intensive care unit.
What characterizes hydroxychloroquine toxicity?
Hydroxychloroquine is an aminoquinoline antibiotic that is classically used as an antimalarial to treat infection with Plasmodium vivax, P ovale, P malariae, and susceptible strains of P falciparum. In the United States, it is more commonly used to manage both rheumatoid arthritis and systemic lupus erythematosus (SLE), debilitating diseases which are estimated to affect anywhere from 161,000 to 322,000 Americans.1 Hydroxychloroquine is considered first-line therapy for SLE, but its mechanism of action in treating SLE-associated arthralgias is unclear.
Hydroxychloroquine is structurally similar to quinine and chloroquine (CQ), and not surprisingly exerts quinidine-like effects on the CV system with resultant negative inotropy and vasodilation. Its toxicity is characterized by rapid onset of clinical effects including central nervous system depression, seizures, apnea, hypotension, and arrhythmia. After large overdoses, cardiac arrest and death can occur within hours.
Hypokalemia is another hallmark of HCQ toxicity. It is thought to develop secondary to potassium channel blockade, which slows the constitutive release of potassium from the myocytes.2 As noted, the hypokalemia is transient and does not reflect whole-body depletion. With CQ, which is considered more toxic, there appears to be a correlation between the quantity of CQ ingested and both the degree of hypokalemia and the severity of the outcome. It is reasonable to assume the same for HCQ. There are little data to support that hypokalemia itself causes cardiotoxicity in patients with CQ or HCQ overdose.
Although lethal doses are not well established, animal studies suggest that HCQ is much less toxic than CQ, for which the clinical toxicity is better understood due to its more widespread use in overdose abroad.3 In children, the reported therapeutic dose is 10 mg/kg, but the minimum reported lethal dose was a single 300-mg tablet (30 mg/kg in a toddler). In adults, the toxic dose is reported as 20 mg/kg with lethal doses suggested to be as low as 30 mg/kg.
What are the treatment modalities for patients with hydroxychloroquine toxicity?
By analogy with the treatment of CQ poisoning, the mainstay of HCQ therapy is supportive care, including early intubation and ventilation to minimize metabolic demand. Direct-acting inotropes and vasopressors should be administered after saline to treat hypotension. Because of its large volume of distribution, extracorporeal removal has not proved to be of clinical value.4,5 Though data are sparse to determine its efficacy, there may be a role for giving activated charcoal, particularly following large overdoses—if it is given early after exposure and the patient has normal consciousness. If the patient is intubated and aspiration risk is minimized, gastric lavage may also be beneficial—especially when performed within an hour of the overdose. Syrup of ipecac should not be used.
High-dose diazepam is typically recommended, again by analogy with CQ, although there is no clear mechanism of action and its use remains controversial. Its protective effect in patients with CQ overdose is based on swine and rat models that demonstrated dose dependent relationships between diazepam and survival.6,7 A prospective study of CQ toxicity in humans reported improved survival rates when high-dose diazepam was given in combination with epinephrine.8 However, this study is limited by its comparison of prospectively studied patients with a retrospective control. A subsequent prospective study of moderately CQ-intoxicated patients did not find a benefit from treatment with diazepam.9 Furthermore, it remains unclear if the proposed benefit from high-dose diazepam in CQ toxicity may be extrapolated to HCQ, and cases of even massive HCQ ingestions report good outcomes without the use of high-dose diazepam.10
How aggressively should hypokalemia in hydroxychloroquine toxicity be treated?
As noted earlier, hypokalemia resulting from HCQ toxicity is transient, and aggressive repletion may result in rebound hyperkalemia once toxicity resolves. However, these dangers should be balanced with risks of hypokalemia-induced ventricular arrhythmias. Additionally, hypokalemia may be worsened by sodium bicarbonate that is administered to correct QRS prolongations, increasing the risk of dysrhythmia. Correction of hypokalemia in these cases is necessary but should be done with care and monitoring of serum potassium concentrations to minimize risk of hyperkalemia-induced ventricular arrhythmia.11
Case Conclusion
Throughout treatment, the patient remained neurologically intact. She did not receive benzodiazepines. The epinephrine and norepinephrine infusions were weaned, and she was discharged on hospital day 3 with no neurological or cardiac sequelae. She received an inpatient psychiatric evaluation and was referred to outpatient services for ongoing care.

First EDition: Regulation of Freestanding EDs, more
Regulation of Freestanding EDs Varies Widely by State
BY JEFF BAUER
There is great variation in state regulations concerning freestanding EDs, with no standard requirements for location, staffing patterns, or clinical capabilities, according to a recent study published in Health Affairs.
Researchers used information from state departments of health and other state agencies to compile a list of freestanding EDs in the United States. They identified state policies and regulations regarding freestanding EDs by contacting state departments of health, by searching the departments’ Web sites for regulations, and by searching an online legal research database.
Overall, the study identified 400 freestanding EDs in 32 states; Texas and Ohio had the highest number of such facilities. Twenty-three states had hospitals that operated affiliated freestanding EDs. Twenty-one states had policies concerning freestanding EDs. These policies were either incorporated into hospital regulations or listed independently. Among states with such regulations, there was great variation in the requirements for freestanding EDs to provide specific medical services, products, and technology. For example, 12 states with freestanding EDs required pediatric equipment to be on site, 13 required a cardiac defibrillator, and 9 required blood products for transfusion. Only two of the 32 states (6%) had policies that were in concordance with all seven of the American College of Emergency Physicians (ACEP) recommendations for freestanding EDs.
Twenty-nine states had no regulations. New York and Washington regulate freestanding EDs on a case-by-case basis, and California indirectly bars them in its hospital regulations.
The study’s authors concluded that variations in state regulations may lead to more freestanding EDs opening in states with fewer regulations, and fewer facilities in states with stricter regulations. They added that consistent regulation of freestanding EDs is needed so patients can better understand these facilities’ capabilities and costs.

Psychiatric Patients Face Inordinately Long Wait Times in EDs
Deepak Chitnis
FRONTLINE MEDICAL NEWS
Individuals with psychiatric conditions are facing increasingly longer wait times in EDs across the country, including children, according to a pair of studies presented at the American College of Emergency Physicians (ACEP) 2016 annual meeting.
Suzanne Catherine Lippert, MD, of Stanford University and the lead author of both studies, said that seeing psychiatric patients sit in the ED for days prompted her to finally look into this issue.
Both studies were conducted retrospectively, looking at data from the National Hospital Ambulatory Medical Care Survey (NHAMCS) collected between 2001 and 2011, and focusing on patients who had been brought to mental health EDs with International Classification of Diseases, Ninth Revision codes indicating substance abuse or a primary psychiatric diagnosis. The first study, which looked at ED length of stay for psychiatric patients, defined length of stay as the time from the patient’s arrival at the ED to the time of disposition, divided into categories of >6 hours, >12 hours, and >24 hours. Overall, 65 million ED visits were included in the study.
Patients with bipolar disorder had the highest likelihood of waiting more than 24 hours in the ED, with an odds ratio of 3.7 (95% confidence interval, 1.5-9.4). This was followed by patients with a diagnosis of psychosis, a dual diagnosis of psychiatric disorders, multiple psychiatric diagnoses, or depression. The most common diagnoses were substance abuse, anxiety, and depression, which constituted 41%, 26%, and 23% of the diagnoses, respectively. Patients with psychosis were admitted 34% of the time and transferred 24% of the time; those who self-harmed were admitted 33% of the time and transferred 29% of the time; and patients with bipolar disorder were admitted 29% of the time and transferred 40% of the time. Patients who had either two or three diagnoses were admitted 9% and 10% of the time, respectively.
“Further investigation of the systems affecting these patients, including placement of involuntary holds, availability of ED psychiatric consultants, or outpatient resources would delineate potential intervention points for the care of these vulnerable patients,” Dr Lippert and her coauthors wrote.
The second study looked at the differences in waiting for care at EDs between psychiatric patients and medical patients. Length of stay was defined the same way it was in the previous study, with disposition meaning either “discharge, admission to medical or psychiatric bed, [or] transfer to any acute facility.” Length of stay was divided into the same three categories as the previous study.
Psychiatric patients were more likely than medical patients to wait more than 6 hours for disposition, regardless of what the disposition ended up being, by a rate of 23% vs 10%. Similarly, 7% of psychiatric patients vs just 2.3% of medical patients had to wait longer than 12 hours in the ED, while 1.3% of psychiatric patients had to wait longer than 24 hours, compared with only 0.5% of medical patients. The average length of stay was significantly longer for psychiatric patients: 194 minutes vs 138 minutes for medical patients (P < .01).
Additionally, psychiatric patients were more likely to be uninsured, with 22% not having insurance, compared with 15% of medical patients being uninsured. Furthermore, 4.6% of the psychiatric patients’ previous visit to the ED had been within the prior 72 hours, compared with 3.6% of medical patients. A total of 21% of psychiatric patients required admission, compared with 13% of medical patients, while 11% of psychiatric patients were transferred, compared with just 1.4% of medical patients.
“These results compel us to further investigate the potential causes of prolonged length of stay in psychiatric patients and to further characterize the population of psychiatric patients most at risk of prolonged stays,” Dr Lippert and her coinvestigators concluded.
American College of Emergency Physicians President Rebecca B. Parker, MD, explained that a survey of more than 1,700 emergency physicians revealed some “troubling” findings about the state of EDs over the last year.
The nation’s dwindling mental health resources are having a direct impact on patients having psychiatric emergencies, including children, Dr Parker said. “These patients are waiting longer for care, especially those patients who require hospitalization.”
Findings of the survey indicate that 48% of ED physicians witness psychiatric patients being “boarded” in their EDs at least once a day while they wait for a bed. Additionally, <17% of respondents said their ED has a psychiatrist on call to respond to psychiatric emergencies, with 11.7% responding that they have no psychiatrist on call to deal with such emergencies. And 52% of respondents said the mental health system in their community has become noticeably worse in just the last year.
Dr Parker voiced outrage about the situation. “Psychiatric patients wait in the emergency department for hours and even days for a bed, which delays the psychiatric care they so desperately need,” she said. “It also leads to delays in care and diminished resources for other emergency patients. The emergency department has become the dumping ground for these vulnerable patients who have been abandoned by every other part of the health care system.”

High Resting Heart Rate May Signal Exacerbation Risk in COPD Patients
Doug Brunk
Frontline Medical News
Higher resting heart rate (HR) may predict future risk of exacerbation in patients with recent chronic obstructive pulmonary disease (COPD) exacerbation, results from a multicenter study suggest.
“Resting heart [rate] is often...readily available clinical data,” lead study author Ahmad Ismail, MD, said in an interview in advance of the annual meeting of the American College of Chest Physicians. “Its significance is often overlooked in daily clinical practice until tachycardia or bradycardia happens. In COPD patients, it has been shown that the resting HR can predict mortality. However, there is a lack of data showing its association with the rates of exacerbations, the major player in determining overall outcome in patients with COPD.”
In an effort to identify the association between resting HR and risk of exacerbations, Dr Ismail of Universiti Teknologi MARA, Malaysia, and his associates at nine other centers evaluated 147 COPD patients who were recruited during acute exacerbation of COPD that required hospitalization between April 2012 and September 2015. The researchers recorded each patient’s sociodemographic data, anthropometric indices, and medication history during their acute exacerbation at the hospital. Next, they followed up with the patients in clinic at 3 months after the recruitment (month 0), and collected resting HR, spirometry, and COPD Assessment Test (CAT) scores. Subsequently, patients were followed up in clinic at 6 and 12 months, and followed up in between via telephone interviews to collect data on exacerbation history.
The mean age of the study population was 67 years, and 77% had higher resting HR, defined as exceeding 80 beats/min (bpm). The mean resting HR in the higher resting HR group was 92 bpm, compared with a mean of 70 bpm in the lower resting HR group. Dr Ismail reported that at month 3, patients with higher resting HR had a significantly higher proportion of exacerbations, compared with those who had a lower resting HR (54% vs 27%; P = .013). The trend was followed through until month 9. There was also a statistically significant moderate strength linear correlation between resting HR and exacerbation frequency at 3, 6, and 9 months (r = 0.400, P < .001; r = 0.440, P < .001; and r = 0.416, P = .004, respectively). The mean exacerbation frequency was also significantly higher in the higher resting HR group at month 3 and month 6 (2.00 vs 0.48, P < .001; and 3.42 vs 1.14, P = .004).
“Higher resting heart rate may predict future risk of exacerbation in patients with recent COPD exacerbation,” Dr Ismail concluded. “Further study however is required to determine the effect of lowering resting heart rate on the future risk of exacerbation.” He acknowledged certain limitations of the study, including the fact that it excluded patients who were on beta-blockers or any rate-modifying drugs, and those with history of cardiac failure and ischemic heart disease, and that there was no baseline echocardiogram performed to ensure the absence of ischemic heart disease and other possible causes of the higher resting HR. “We also had slightly higher than expected dropouts giving a nonsignificant result at 12 months follow-up, though the trend follows the overall results of the study,” he said.
Regulation of Freestanding EDs Varies Widely by State
BY JEFF BAUER
There is great variation in state regulations concerning freestanding EDs, with no standard requirements for location, staffing patterns, or clinical capabilities, according to a recent study published in Health Affairs.
Researchers used information from state departments of health and other state agencies to compile a list of freestanding EDs in the United States. They identified state policies and regulations regarding freestanding EDs by contacting state departments of health, by searching the departments’ Web sites for regulations, and by searching an online legal research database.
Overall, the study identified 400 freestanding EDs in 32 states; Texas and Ohio had the highest number of such facilities. Twenty-three states had hospitals that operated affiliated freestanding EDs. Twenty-one states had policies concerning freestanding EDs. These policies were either incorporated into hospital regulations or listed independently. Among states with such regulations, there was great variation in the requirements for freestanding EDs to provide specific medical services, products, and technology. For example, 12 states with freestanding EDs required pediatric equipment to be on site, 13 required a cardiac defibrillator, and 9 required blood products for transfusion. Only two of the 32 states (6%) had policies that were in concordance with all seven of the American College of Emergency Physicians (ACEP) recommendations for freestanding EDs.
Twenty-nine states had no regulations. New York and Washington regulate freestanding EDs on a case-by-case basis, and California indirectly bars them in its hospital regulations.
The study’s authors concluded that variations in state regulations may lead to more freestanding EDs opening in states with fewer regulations, and fewer facilities in states with stricter regulations. They added that consistent regulation of freestanding EDs is needed so patients can better understand these facilities’ capabilities and costs.

Psychiatric Patients Face Inordinately Long Wait Times in EDs

Individuals with psychiatric conditions are facing increasingly longer wait times in EDs across the country, including children, according to a pair of studies presented at the American College of Emergency Physicians (ACEP) 2016 annual meeting.
Suzanne Catherine Lippert, MD, of Stanford University and the lead author of both studies, said that seeing psychiatric patients sit in the ED for days prompted her to finally look into this issue.
Both studies were conducted retrospectively, looking at data from the National Hospital Ambulatory Medical Care Survey (NHAMCS) collected between 2001 and 2011, and focusing on patients who had been brought to mental health EDs with International Classification of Diseases, Ninth Revision codes indicating substance abuse or a primary psychiatric diagnosis. The first study, which looked at ED length of stay for psychiatric patients, defined length of stay as the time from the patient’s arrival at the ED to the time of disposition, divided into categories of >6 hours, >12 hours, and >24 hours. Overall, 65 million ED visits were included in the study.
Patients with bipolar disorder had the highest likelihood of waiting more than 24 hours in the ED, with an odds ratio of 3.7 (95% confidence interval, 1.5-9.4). This was followed by patients with a diagnosis of psychosis, a dual diagnosis of psychiatric disorders, multiple psychiatric diagnoses, or depression.

Bertrand M. Bell, MD: An Iconoclast Who Became an Icon
Bertrand M. Bell, MD, Distinguished University Professor Emeritus at Albert Einstein College of Medicine, died at the age of 86 in his Manhattan home on October 4, 2016. For decades, Dr Bell was the Director of Ambulatory Care, which included the ED at Einstein’s teaching hospital, the Bronx Municipal (Jacobi) Hospital Center. But, as Dr Bell was aware for the last 25 years of his life, he would always be remembered for a committee he chaired the year he was on sabbatical from Einstein and Jacobi in 1987.
After the death of 18-year-old Libby Zion from a dangerous drug interaction, the New York State Commissioner of Health asked Dr Bell to chair an ad hoc committee to investigate the care of hospitalized patients by residents and to make recommendations regarding medication ordering and administration, the use of patient restraints, attending supervision, and resident work hours. The “Bell Commission,” as it came to be known, recommended that residents not be allowed to work more than 80 hours a week or more than 24 consecutive hours, and that attending physicians be present in the hospital 24/7. These recommendations were made part of the New York State Health Code in 1989 and adopted nationwide by the Accreditation Council for Graduate Medical Education in 1993.
The Bell Commission changes in resident work hours were not enthusiastically received by all, with most of the criticism centering on a perceived lack of continuity in resident education resulting from the shortened work hours. Largely ignored, however, was the committee’s call for 24/7 attending supervision, which would have provided both continuity in patient care and enhanced resident education and experiences. Dr Bell was outspoken in defending his committee’s recommendations and his views on the inadequacies of graduate medical education (GME), occasionally infuriating those who disagreed with him.
Ironically, though the formal name of the Bell Commission was the “Ad Hoc Advisory Committee on Emergency Services,” the recommendations did not address prehospital care issues and probably affected emergency medicine (EM) residents less than they did residents from other specialties. Both the work-hour rules and mandated attending presence had already been implemented by many EM residency training programs from the time EM became a specialty in 1979, and were required of all EM programs by the end of the 1980s. (See “’My Patient’—More Than Ever,” Emerg Med. 2013;45[4]:1.)
Yet, Bert Bell may have had as profound an effect on the birth and survival of academic EM on the East Coast as did his committee’s recommendations on GME nationwide. Together with his ED Director, Sheldon Jacobson, MD, Bert secured for Einstein/Jacobi the first federally funded paramedic training program in New York State in 1974, followed a year later by the first EM residency in New York State, and one of the earliest in the nation. Bert also hired and trained nurse practitioners and physician assistants to care for patients in the ED and clinics, realizing their potential and the value of their contributions to patient care, years before others did.
The group of emergency physicians that Bert and Shelly assembled at Einstein/Jacobi in the 1970s included John Gallagher, Peter Moyer, Mark Henry, Gregg Husk, Paul Gennis, a young Wallace Carter, me, and several other EM pionee
At Dr Bell’s funeral on October 7, the rabbi alluded to a description of the prophet Elijah, in describing Bert as a “holy troublemaker.” Bert Bell was a larger-than-life iconoclast whose name became an icon for graduate medical education reforms and whose patient care values will survive in future generations of physicians.

Together with his ED Director, Sheldon Jacobson, MD, Bert secured for Einstein/Jacobi the first federally funded paramedic training program in New York State in 1974, followed a year later by the first EM residency in New York State, and one of the earliest in the nation. Bert also hired and trained nurse practitioners and physician assistants to care for patients in the ED and clinics, realizing their potential and the value of their contributions to patient care, years before others did.
The group of emergency physicians that Bert and Shelly assembled at Einstein/Jacobi in the 1970s included John Gallagher, Peter Moyer, Mark Henry, Gregg Husk, Paul Gennis, a young Wallace Carter, me, and several other EM pionee
At Dr Bell’s funeral on October 7, the rabbi alluded to a description of the prophet Elijah, in describing Bert as a “holy troublemaker.” Bert Bell was a larger-than-life iconoclast whose name became an icon for graduate medical education reforms and whose patient care values will survive in future generations of physicians.
Bertrand M. Bell, MD, Distinguished University Professor Emeritus at Albert Einstein College of Medicine, died at the age of 86 in his Manhattan home on October 4, 2016. For decades, Dr Bell was the Director of Ambulatory Care, which included the ED at Einstein’s teaching hospital, the Bronx Municipal (Jacobi) Hospital Center. But, as Dr Bell was aware for the last 25 years of his life, he would always be remembered for a committee he chaired the year he was on sabbatical from Einstein and Jacobi in 1987.
After the death of 18-year-old Libby Zion from a dangerous drug interaction, the New York State Commissioner of Health asked Dr Bell to chair an ad hoc committee to investigate the care of hospitalized patients by residents and to make recommendations regarding medication ordering and administration, the use of patient restraints, attending supervision, and resident work hours. The “Bell Commission,” as it came to be known, recommended that residents not be allowed to work more than 80 hours a week or more than 24 consecutive hours, and that attending physicians be present in the hospital 24/7. These recommendations were made part of the New York State Health Code in 1989 and adopted nationwide by the Accreditation Council for Graduate Medical Education in 1993.
The Bell Commission changes in resident work hours were not enthusiastically received by all, with most of the criticism centering on a perceived lack of continuity in resident education resulting from the shortened work hours. Largely ignored, however, was the committee’s call for 24/7 attending supervision, which would have provided both continuity in patient care and enhanced resident education and experiences. Dr Bell was outspoken in defending his committee’s recommendations and his views on the inadequacies of graduate medical education (GME), occasionally infuriating those who disagreed with him.
Ironically, though the formal name of the Bell Commission was the “Ad Hoc Advisory Committee on Emergency Services,” the recommendations did not address prehospital care issues and probably affected emergency medicine (EM) residents less than they did residents from other specialties. Both the work-hour rules and mandated attending presence had already been implemented by many EM residency training programs from the time EM became a specialty in 1979, and were required of all EM programs by the end of the 1980s.

Caution is key when prescribing spironolactone for adult acne
NEWPORT BEACH, CALIF. – While off-label use of spironolactone for treatment of acne is quite common, it should be prescribed with special caution, advised Julie C. Harper, MD.
“The vast majority of you write this for acne,” Dr. Harper, a dermatologist in private practice in Birmingham, Ala., said during a presentation on adult acne at the Skin Disease Education Foundation’s Women’s & Pediatric Dermatology Seminar.
She offered this blunt advice about one potential patient group: “Do not use this in men.” She cited a 2006 Japanese study of 139 patients with acne, treated with oral spironolactone, which found that 3 of the 23 males in the study developed gynecomastia within 4-6 weeks. Subsequently, the treatment was stopped in all male patients (Aesthetic Plast Surg. 2006 Nov-Dec;30[6]:689-94).
In the same study, 80% of the 116 females in the study experienced menstrual irregularities. “We have to tell our patients that’s a possible side effect, that they may get breast tenderness or menstrual irregularities,” Dr. Harper said. “If you don’t tell them, they’re not thinking of acne drugs as causing this.”
What about the risk of hyperkalemia in patients who take spironolactone, which is a diuretic? A retrospective study found similar hyperkalemia rates among healthy young women taking spironolactone for acne or an endocrine disorder with associated acne (mean age 26-27 years) and among healthy young women not taking spironolactone. The authors concluded that routine potassium testing was not necessary in healthy young women who take the drug (JAMA Dermatol. 2015 Sep;151[9]:941-4).
Dr. Harper recommended testing, however, if patients are older, have a history of renal or cardiac disease, have impaired hepatic function, or are taking higher doses of spironolactone.
She also cautioned that spironolactone should not be taken with lithium, and that it boosts the risk of digoxin toxicity.
Research doesn’t indicate that the risk of breast cancer is increased in women taking spironolactone, she said, nor does there appear to be a risk in lactating mothers. But the drug should not be taken during pregnancy or by women who could become pregnant, she noted.
Dr. Harper warned against the use of tetracyclines and erythromycin estolate when treating pregnant women with acne. She avoids using topical retinoids, although she said they are probably safe in small areas. Benzoyl peroxide is acceptable for small areas, as are topical azelaic acid and clindamycin, she added.
For information about acne treatment in lactating mothers, she cited a 2014 review (J Am Acad Dermatol. 2014 Mar;70[3]:417.e1-417.e10.). Erythromycin, azithromycin, and clarithromycin are considered appropriate for short-term use, she said, as are tetracyclines, but for less than 3 weeks only. Oral clindamycin is acceptable, but may cause gastrointestinal side effects in the nursing infant; topical use appears to be appropriate, she said.
Topical treatment with benzoyl peroxide is also appropriate for lactating women, she said, and topical retinoids are probably safe on small areas. Topical azelaic acid is considered a low risk to the nursing infant, she added.
Dr. Harper disclosed financial relationships of various types with Allergan, Bayer, BiopharmX, Galderma, Novan, Promius and Valeant.
