A Cross-Sectional Analysis of High-Acuity Professional Services Performed by Urban and Rural Emergency Care Physicians Across the United States.

STUDY OBJECTIVE: We seek to examine differences in the provision of high-acuity professional services between rural and urban physicians receiving reimbursement for emergency care evaluation and management services from Medicare fee-for-service Part B. METHODS: Using the 2017 Medicare Public Use Files, we performed a cross-sectional analysis and defined the primary outcome, the proportion of high-acuity charts (PHAC), at the physician level as the proportion of services provided as 99285 and 99291 emergency care evaluation and management service codes relative to all such codes. After accounting for unique clinician-level characteristics, we categorized individual physicians by PHAC quintiles and conducted ordered logistic regression analyses reporting adjusted marginal probabilities to examine associations with rurality. RESULTS: A total of 34,256 physicians providing emergency care had a median PHAC of 66.8% (interquartile range 55.6% to 75.7%), with 89.2% practicing in an urban setting. Urban and rural physicians had respective median PHACs of 67.6% (interquartile range 57.1% to 76.2%) and 57.9% (interquartile range 42.7% to 69.4%). Urban and rural physicians had respective adjusted marginal probabilities of 15.2% and 11.8% of being in the highest PHAC quintile, and respective adjusted marginal probabilities of 14.3% and 18.2% of being in the lowest PHAC quintile. CONCLUSION: In comparison with rural physicians, urban physicians providing emergency care received reimbursements for a greater PHAC when caring for Medicare fee-for-service beneficiaries. Policymakers must consider these differences in the design and implementation of new emergency care payment policies.

A Qualitative Study of Risks Related to Interhospital Transfer of Patients with Nontraumatic Intracranial Hemorrhage.

GOAL: Interhospital transfer (IHT) facilitates access to specialized neurocritical care but may also introduce unique risk. Our goal was to describe providers' perceptions of safety threats during IHT for patients with nontraumatic intracranial hemorrhage. MATERIALS AND METHODS: We employed qualitative, semi-structured interviews at an academic medical center receiving critically-ill neurologic transfers, and 5 referring hospitals. Interviewees included physicians, nurses, and allied health professionals with experience caring for patients transferred between hospitals for nontraumatic intracranial hemorrhage. Interviews continued until data saturation was reached. Coding occurred concurrently with interviews. Analysis was inductive, using the constant comparative method. FINDINGS: The predominant impediments to safe, high-quality neurocritical care transitions between hospitals are insufficient communication, gaps in clinical practice, and lack of IHT structure. Insufficient communication highlights the unique communication challenges specific to IHT, which overlay and compound known intrahospital communication barriers. Gaps in clinical practice revolve primarily around the provision of neurocritical care for this patient population, often subject to resource availability, by receiving hospital emergency medicine providers. Lack of structure outlines providers' questions that emerge when institutions fail to identify process channels, expectations, and accountability during complex neurocritical care transitions. CONCLUSIONS: The predominant impediments to safe, high-quality neurocritical care transitions between hospitals are insufficient communication, gaps in clinical practice, and lack of IHT structure. These themes serve as fundamental targets for quality improvement initiatives. To our knowledge, this is the first description of challenges to quality and safety in high-risk neurocritical care transitions through clinicians' voices.

Impact of an emergency department closure on the local emergency medical services system.

BACKGROUND: On July 12, 2010, Boston Medical Center (BMC), the busiest emergency department (ED) in Massachusetts, with more than 100,000 adult patient visits per year, consolidated its two fully functional EDs into one. In preparation for this consolidation, BMC implemented systems changes to mitigate potential negative effects on both BMC and emergency medical services (EMS) providers, including Boston Emergency Medical Services (Boston EMS), the provider of 9-1-1 EMS to the City of Boston. OBJECTIVE: To examine the impact of the closure of an ED on an urban EMS system in a setting where ambulance diversion is not allowed. METHODS: We performed a before-and-after study that examined the effects of an ED closure on BMC and Boston EMS. We examined ED and Boston EMS volumes and ambulance turnaround intervals from June 1, 2010, to July 11, 2010 (preclosure) as compared with July 12, 2010, to August 26, 2010 (postclosure). Mean ED and Boston EMS volumes and Boston EMS turnaround intervals were calculated in four-hour shifts. We used multivariate analysis to analyze electronic medical systems data from BMC and Boston EMS and linear regression. We used autoregressive integrated moving average (ARIMA) models to determine the effect of the ED closure on turnaround intervals, ED volumes, and transport volumes. All analyses were adjusted for shift, ED volume, day of the week, and citywide EMS transport volumes. RESULTS: After ED closure, there was a statistically significant increase of 0.89 minutes (p = 0.02) in the mean EMS turnaround intervals. Additionally, the total ED volume decreased by 3.67 visits per shift (p < 0.001). The ratio of patients transported by Boston EMS to BMC remained unchanged (p = 0.11) for two weeks before and two weeks after the closure. CONCLUSIONS: The closure of one ED resulted in a statistically significant increase in turnaround intervals and a significant decrease in ED volume independent of EMS volumes. In the absence of ambulance diversion, ratios of EMS turnaround intervals and EMS volumes according to hospital destination can be used as alternatives to ambulance diversion times to examine the effects of system-level changes such as closure of an ED on an urban EMS system.

High-risk chief complaints II: disorders of the head and neck.

Of the many different complaints of patients presenting to the emergency department, some of the most difficult to diagnose and manage involve pathology of the head and neck. Often diagnoses of conditions affecting this part of the body are elusive, and occasionally, even once the diagnosis has been made, the management of these disorders remains challenging. This article addresses some of the high-risk chief complaints of the head and neck regarding diagnosis and management. These complaints include headache, seizure, acute focal neurologic deficits, throat and neck pain, ocular emergencies, and the difficult airway.

Abdominal 64-MDCT for suspected appendicitis: the use of oral and IV contrast material versus IV contrast material only.

OBJECTIVE: The objective of our study was to compare the diagnostic accuracy of IV contrast-enhanced 64-MDCT with and without the use of oral contrast material in diagnosing appendicitis in patients with abdominal pain. MATERIALS AND METHODS: We conducted a randomized trial of a convenience sample of adult patients presenting to an urban academic emergency department with acute nontraumatic abdominal pain and clinical suspicion of appendicitis, diverticulitis, or small-bowel obstruction. Patients were enrolled between 8 am and 11 pm when research assistants were present. Consenting subjects were randomized into one of two groups: Group 1 subjects underwent 64-MDCT performed with oral and IV contrast media and group 2 subjects underwent 64-MDCT performed solely with IV contrast material. Three expert radiologists independently reviewed the CT examinations, evaluating for the presence of appendicitis. Each radiologist interpreted 202 examinations, ensuring that each examination was interpreted by two radiologists. Individual reader performance and a combined interpretation performance of the two readers assigned to each case were calculated. In cases of disagreement, the third reader was asked to deliver a tiebreaker interpretation to be used to calculate the combined reader performance. Final outcome was based on operative, clinical, and follow-up data. We compared radiologic diagnoses with clinical outcomes to calculate the diagnostic accuracy of CT in both groups. RESULTS: Of the 303 patients enrolled, 151 patients (50%) were randomized to group 1 and the remaining 152 (50%) were randomized to group 2. The combined reader performance for the diagnosis of appendicitis in group 1 was a sensitivity of 100% (95% CI, 76.8-100%) and specificity of 97.1% (95% CI, 92.7-99.2%). The performance in group 2 was a sensitivity of 100% (73.5-100%) and specificity of 97.1% (92.9-99.2%). CONCLUSION: Patients presenting with nontraumatic abdominal pain imaged using 64-MDCT with isotropic reformations had similar characteristics for the diagnosis of appendicitis when IV contrast material alone was used and when oral and IV contrast media were used.

Alcohol-related seizures.

Alcohol-related seizures are defined as adult-onset seizures that occur in the setting of chronic alcohol dependence. Alcohol withdrawal is the cause of seizures in a subgroup of these patients; however, concurrent risk factors including pre-existing epilepsy, structural brain lesions, and the use of illicit drugs contribute to the development of seizures in many patients. New onset or a new pattern of alcohol-related seizures, e.g., focal seizures or status epilepticus, should prompt a thorough diagnostic evaluation. This is not indicated if patients have previously completed a comprehensive evaluation and the pattern of current seizures is consistent with past events. Treatment is initially directed at aggressively terminating current seizure activity. This should be followed by prevention of recurrent alcohol-related seizures and progression to status epilepticus during the ensuing 6-h high-risk period. Our purpose is to present recommendations for the diagnostic evaluation, treatment and disposition of these patients based on the current literature.

Hypothermia and localized cold injuries.

Hypothermia and localized cold injuries are largely preventable with proper preparation for activities in cold environments. Proficient field management is crucial to the final outcome in terms of function and viability because proper care is vital to preventing exacerbation of the initial exposure and injury. Rapid rewarming is optimal when further cold exposure can be avoided reliably. Repetitive freeze-thaw cycles are associated with increased morbidity and tissue loss caused by progressive microvascular injury and thrombosis. The subsequent care is largely supportive and consists of wound care and physical and hydrotherapy to promote optimal functional recovery.
