Patient Perceptions of Emergency Department Observation Care at Home.

Introduction: The Virtual Observation Unit (VOU) utilizes telehealth and community paramedicine to provide observation-level care in patients' homes. Patients' experience of this novel program has not been reported. Methods: A phone-based patient experience survey was administered to the patients who were admitted to the VOU at an urban, academic Emergency Department in the Northeast United States. The survey asked about patient's perception of the program's quality of care (0 = worst care possible, 10 = best care possible). t Tests with a Bonferroni adjustment assessed for differences between patient demographic groups. Results: The survey response rate was 40% (124/307). Overall mean scores for perceived quality of care were very high (9.51 ± 1.19). There were no significant differences in patient's perception of quality of care between demographic cohorts of age, gender, race, or ethnicity. Conclusions: Patient experience with a novel VOU program was very positive and did not differ significantly by demographic cohort. Further research is warranted.

The Value of an Emergency Medicine Virtual Observation Unit.

STUDY OBJECTIVE: We implemented a virtual observation unit in which emergency department (ED) patients receive observation-level care at home. Our primary aim was to compare this new care model to in-person observation care in terms of brick-and-mortar ED length of stay (inclusive of ED observation unit time) as well as secondarily on inpatient admission and 72-hour return visits (overall and with admission). METHODS: In a retrospective analysis of electronic health record data on ED observation patients from January 1, 2022 to December 29, 2022 from an academic urban ED, we used propensity matching to compare virtual to in-person observation patients on outcomes of interest. Patients were matched 1:1 based on age, sex, Charlson Comorbidity Index, and reason for observation. We also conducted real-time review of all virtual observation cases for potential safety concerns. RESULTS: Of 8,218 observation stays, 361 virtual observation patients were matched with 361 in-person observation patients. Virtual observation patients experienced lower median brick-and-mortar ED + EDOU LOS [14.6 (IQR 10.2, 18.9) versus 33.3 (IQR 28.1, 38.1) hours] and lower inpatient admission rates (10.2% [SD 5.0] versus 24.7% [SD 11.3]). The 72-hour return rate was higher for virtual observation patients (3.6% [SD 3.0] versus 2.5% [SD 3.0]). Among those with return visits, the rate of inpatient admission was higher among virtual observation patients (53.8% [SD 3.2] versus 11.1% [13.0]). There were no significant patient safety events recorded. CONCLUSION: Virtual observation unit patients used fewer hours in ED and ED observation relative to on-site observation patients. This new care delivery model warrants further study because it has the potential to positively impact ED capacity.

Factors Associated with the Digital Patient Experience of Virtual Care Across Specialties.

Background: We aimed to characterize patient experience with virtual care across medical specialties using validated survey data. Primary objective: to determine whether experience varied by visit modality (virtual vs. in-person) and whether relationships persisted after adjusting for patient and provider characteristics. Secondarily, among physicians with sufficient data, we compared virtual versus in-person patient experience scores at the physician level and identified characteristics associated with better experience scores for virtual care. Methods: This was a retrospective analysis of administrative databases from a large New England health care system, including all ambulatory visits from October 1, 2020 to September 30, 2021 with patient experience scores recorded. We compared experience between virtual and in-person at the visit level (score: 0-10) and the physician level for likelihood of recommending the physician to friends or family. We used a series of cross-classified hierarchical models with visits grouped by patient and by physician to decompose sources of variation. Among physicians with sufficient data, we compared physicians with higher virtual versus higher in-person net promoter score (NPS). Results: Of 378,472 visits performed by 3368 physicians, 86,878 (23%) were conducted virtually. Most scored ≥9 for either modality, with a small preference for virtual versus in-person care (9.6 vs. 9.5, p < 0.001). We found that more variation in scores was explained by patient than by physician (22.9% vs. 3%). Visit modality was of minimal explanatory value. Most physicians' virtual and in-person NPS were similar, and virtual visit volume was not associated. Conclusions: We found robust evidence for the parity of patient experience between virtual and in-person modalities across specialties.

Can tablet video-based telehealth assessment of the abdomen safely determine the need for abdominal imaging? A pilot study.

Objective: There is limited evidence on the reliability of video-based physical examinations. We aimed to evaluate the safety of a remote physician-directed abdominal examination using tablet-based video. Methods: This was a prospective observational pilot study of patients >19 years old presenting with abdominal pain to an academic emergency department July 9, 2021-December 21, 2021. In addition to usual care, patients had a tablet video-based telehealth history and examination by an emergency physician who was otherwise not involved in the visit. Both telehealth and in-person clinicians were asked about the patient's need for abdominal imaging (yes/no). Thirty-day chart review searched for subsequent ED visits, hospitalizations, and procedures. Our primary outcome was agreement between telehealth and in-person clinicians on imaging need. Our secondary outcome was potentially missed imaging by the telehealth physicians leading to morbidity or mortality. We used descriptive and bivariate analyses to examine characteristics associated with disagreement on imaging needs. Results: Fifty-six patients were enrolled; the median age was 43 years (interquartile range: 27-59), 31 (55%) were female. The telehealth and in-person clinicians agreed on the need for imaging in 42 (75%) of the patients (95% confidence interval [CI]: 62%-86%), with moderate agreement with Cohen's kappa ((k = 0.41, 95% CI: 0.15-0.67). For study patients who had a procedure within 24 hours of ED arrival (n = 3, 5.4%, 95% CI: 1.1%-14.9%) or within 30 days (n = 7, 12.5%, 95% CI: 5.2%-24.1%), neither telehealth physicians nor in-person clinicians missed timely imaging. Conclusion: In this pilot study, telehealth physicians and in-person clinicians agreed on the need for imaging for the majority of patients with abdominal pain. Importantly, telehealth physicians did not miss the identification of imaging needs for patients requiring urgent or emergent surgery.

Patient Experience With an In-Home COVID Virtual Observation Unit: An Analysis.

We performed a retrospective cohort study of patients admitted to a novel, home-based COVID Virtual Observation Unit (CVOU) from an urban, university-affiliated emergency department with ∼112,000 annual visits. Telephone-based survey questions were administered by nursing staff working with the program. Of 402 patients enrolled in the CVOU, 221 (55%) were able to be contacted during the study period; 180 (45%) agreed to participate in the telephone interview. Overall, 95% (169 out of 177) of the surveyed patients reported 8 to 10 on the likelihood to recommend CVOU and 82% (100 out of 122) rated the quality of care as 10 out of 10. Over 90% of respondents reported that all role groups (nurses, paramedics, and physicians) treated them with courtesy and respect, explained things in an understandable way, and listened to them carefully. Over 80% of respondents reported that the program kept them at home. In summary, patient experiences with this novel home-based care program were highly positive. These data help underscore the importance of patient-centeredness in home-based care, and further support the concept of these innovative care models.

Machine Learning Methods for Predicting Patient-Level Emergency Department Workload.

BACKGROUND: Work Relative Value Units (wRVUs) are a component of many compensation models, and a proxy for the effort required to care for a patient. Accurate prediction of wRVUs generated per patient at triage could facilitate real-time load balancing between physicians and provide many practical operational and clinical benefits. OBJECTIVE: We examined whether deep-learning approaches could predict the wRVUs generated by a patient's visit using data commonly available at triage. METHODS: Adult patients presenting to an urban, academic emergency department from July 1, 2016-March 1, 2020 were included. Deidentified triage information included structured data (age, sex, vital signs, Emergency Severity Index score, language, race, standardized chief complaint) and unstructured data (free-text chief complaint) with wRVUs as outcome. Five models were examined: average wRVUs per chief complaint, linear regression, neural network and gradient-boosted tree on structured data, and neural network on unstructured textual data. Models were evaluated using mean absolute error. RESULTS: We analyzed 204,064 visits between July 1, 2016 and March 1, 2020. The median wRVUs were 3.80 (interquartile range 2.56-4.21), with significant effects of age, gender, and race. Models demonstrated lower error as complexity increased. Predictions using averages from chief complaints alone demonstrated a mean error of 2.17 predicted wRVUs per visit (95% confidence interval [CI] 2.07-2.27), the linear regression model: 1.00 wRVUs (95% CI 0.97-1.04), gradient-boosted tree: 0.85 wRVUs (95% CI 0.84-0.86), neural network with structured data: 0.86 wRVUs (95% CI 0.85-0.87), and neural network with unstructured data: 0.78 wRVUs (95% CI 0.76-0.80). CONCLUSIONS: Chief complaints are a poor predictor of the effort needed to evaluate a patient; however, deep-learning techniques show promise. These algorithms have the potential to provide many practical applications, including balancing workloads and compensation between emergency physicians, quantify crowding and mobilizing resources, and reducing bias in the triage process.

Can video-based telehealth examinations of the abdomen safely determine the need for imaging?

There is little evidence on the reliability of the video-based telehealth physical examinations. Our objective was to evaluate the feasibility of a physician-directed abdominal examination using telehealth. This was a prospective, blinded observational study of patients >19 years of age presenting with abdominal pain to a large, academic emergency department. In addition to their usual care, patients had a video-based telehealth examination by an emergency physician early in the visit. We compared the in-person and telehealth providers' decisions on imaging. Thirty patients were enrolled and providers' recommendations for imaging were YES (telehealth: 18 (60%); in-person: 22 (73%)), UNSURE (telehealth: 9 (30%); in-person: 2 (7%)) and NO (telehealth: 6 (20%); in-person: 3 (10%)). There were 20 patients for whom both telehealth and in-person providers were not unsure; of these, 16 (80%, 95% confidence interval 56.3-94.3%) patients had a provider agreement on the need for imaging. While the use of video-based telehealth may be feasible for patients seeking emergency department care for abdominal pain, further study is needed to determine how it may be safely deployed. Currently, caution should be exercised when evaluating the need for abdominal imaging remotely.

Impact of Emergency Department Crowding on Discharged Patient Experience.

INTRODUCTION: While emergency department (ED) crowding has deleterious effects on patient care outcomes and operational efficiency, impacts on the experience for patients discharged from the ED are unknown. We aimed to study how patient-reported experience is affected by ED crowding to characterize which factors most impact discharged patient experience. METHODS: This institutional review board-exempt, retrospective, cohort study included all discharged adult ED patients July 1, 2020-June 30, 2021 with at least some response data to the the National Research Corporation Health survey, sent to most patients discharged from our large, academic medical center ED. Our query yielded 9,401 unique encounters for 9,221 patients. Based on responses to the summary question of whether the patient was likely to recommend our ED, patients were categorized as "detractors" (scores 0-6) or "non-detractors" (scores 7-10). We assessed the relationship between census and patient experience by 1) computing percentage of detractors within each care area and assessing for differences in census and boarder burden between detractors and non-detractors, and 2) multivariable logistic regression assessing the relationship between likelihood of being a detractor in terms of the ED census and the patient's last ED care area. A second logistic regression controlled for additional patient- and encounter-specific covariates. RESULTS: Survey response rate was 24.8%. Overall, 13.9% of responders were detractors. There was a significant difference in the average overall ED census for detractors (average 3.70 more patients physically present at the time of arrival, 95% CI 2.33-5.07). In unadjusted multivariable analyses, three lower acuity ED care areas showed statistically significant differences of detractor likelihood with changes in patient census. The overall area under the curve (AUC) for the unadjusted model was 0.594 (CI 0.577-0.610). The adjusted model had higher AUC (0.673, CI 0.657-.690]; P<0.001), with the same three care areas having significant differences in detractor likelihood based on patient census changes. Length of stay (OR 1.71, CI 1.50-1.95), leaving against medical advice/without being seen (OR 5.15, CI 3.84-6.89), and the number of ED care areas a patient visited (OR 1.16, CI 1.01-1.33) was associated with an increase in detractor likelihood. CONCLUSION: Patients arriving to a crowded ED and ultimately discharged are more likely to have negative patient experience. Future studies should characterize which variables most impact patient experience of discharged ED patients.

Continuation of outpatient buprenorphine therapy after dispensing Buprenorphine-Naloxone from the emergency department.

BACKGROUND: Patients with opioid use disorder (OUD) are frequently seen in the ED for opioid-related reasons, which creates an opportunity for ED providers to discuss medications for OUD with their patients. Buprenorphine is a partial mu-opioid agonist that is FDA approved to treat OUD and may be initiated in the ED. Traditionally, buprenorphine therapy was initiated under healthcare provider observation; however, other strategies such as at-home induction have also emerged. METHODS: This was a retrospective descriptive analysis of patients aged 18 years or older who received a take-home supply of buprenorphine-naloxone from an urban, academic ED between March 2018 and March 2020. The primary outcome was the proportion of patients who filled a prescription for buprenorphine at three months after index ED visit. The proportion of patients that filled a prescription for buprenorphine at six months was also evaluated. The primary safety endpoint was the proportion of patients with return ED visit within six months related to opioid overdose. RESULTS: There were 242 patient records reviewed with 155 patients included in final analysis. Seventy (45.2%) patients filled buprenorphine prescriptions at three months, with 64 (41.3%) who filled buprenorphine prescriptions at six months. Seventeen (11%) patients had a return ED visit related to opioid overdose within six months. CONCLUSION: Dispensing buprenorphine take-home kits from the ED resulted in continuation of outpatient buprenorphine in almost 50% of patients. Further studies are warranted to define the role of ED-dispensed buprenorphine.

Emergency Department-initiated Buprenorphine and Referral to Follow-up Addiction Care: A Program Description.

INTRODUCTION: Emergency department (ED) initiated opioid use disorder (OUD) care is effective; however, real-world predictors of patient engagement are lacking. OBJECTIVE: This program evaluation examined predictors of ED-based OUD treatment and subsequent engagement. METHOD: Program evaluation in Boston, MA. Adult patients who met criteria for OUD during an ED visit in 2019 were included. Patients were included if a diagnosis of OUD or opioid-related overdose was associated with the ED visit or if they met previously validated criteria for OUD within the previous 12 months. We assessed predictors of ED-OUD treatment receipt and subsequent engagement, using Healthcare Effectiveness Data and Information Set definition of initial encounter within 14 days of discharge and either 2 subsequent encounters or a subsequent buprenorphine prescription within 34 days of the initial encounter. We used generalized estimating equations for panel data. RESULTS: During 2019, 1946 patients met criteria for OUD. Referrals to Bridge Clinic were made for 207 (11%), buprenorphine initiated for 106 (5%), and home induction buprenorphine kits given to 56 (3%). Following ED discharge, 237 patients (12%) had a visit within 14 days, 122 (6%) had ≥2 additional visits, and 207 (11%) received a subsequent buprenorphine prescription. Young, White, male patients were most likely to receive ED-OUD care. Patients who received ED-OUD care were more likely to have subsequent treatment engagement (adjusted rate ratio: 2.30, 95% confidence intervals: 1.62-3.27). Referrals were made less often than predicted for Black (-49%) or Hispanic/Latinx (-25%) patients. CONCLUSIONS: Initiating treatment for OUD in the ED was associated with increased engagement in outpatient addiction care.

Clinical Assessment and Validation of a Rapid and Sensitive SARS-CoV-2 Test Using Reverse Transcription Loop-Mediated Isothermal Amplification Without the Need for RNA Extraction.

BACKGROUND: Amid the enduring pandemic, there is an urgent need for expanded access to rapid, sensitive, and inexpensive coronavirus disease 2019 (COVID-19) testing worldwide without specialized equipment. We developed a simple test that uses colorimetric reverse transcription loop-mediated isothermal amplification (RT-LAMP) to detect severe acute resrpiratory syndrome coronavirus 2 (SARS-CoV-2) in 40 minutes from sample collection to result. METHODS: We tested 135 nasopharyngeal specimens from patients evaluated for COVID-19 infection at Massachusetts General Hospital. Specimens were either added directly to RT-LAMP reactions, inactivated by a combined chemical and heat treatment step, or inactivated then purified with a silica particle-based concentration method. Amplification was performed with 2 SARS-CoV-2-specific primer sets and an internal specimen control; the resulting color change was visually interpreted. RESULTS: Direct RT-LAMP testing of unprocessed specimens could only reliably detect samples with abundant SARS-CoV-2 (>3 000 000 copies/mL), with sensitivities of 50% (95% CI, 28%-72%) and 59% (95% CI, 43%-73%) in samples collected in universal transport medium and saline, respectively, compared with quantitative polymerase chain reaction (qPCR). Adding an upfront RNase inactivation step markedly improved the limit of detection to at least 25 000 copies/mL, with 87.5% (95% CI, 72%-95%) sensitivity and 100% specificity (95% CI, 87%-100%). Using both inactivation and purification increased the assay sensitivity by 10-fold, achieving a limit of detection comparable to commercial real-time PCR-based diagnostics. CONCLUSIONS: By incorporating a fast and inexpensive sample preparation step, RT-LAMP accurately detects SARS-CoV-2 with limited equipment for about US$6 per sample, making this a potentially ideal assay to increase testing capacity, especially in resource-limited settings.

The Association of Demographic, Socioeconomic, and Geographic Factors with Potentially Preventable Emergency Department Utilization.

INTRODUCTION: Prevention quality indicators (PQI) are a set of measures used to characterize healthcare utilization for conditions identified as being potentially preventable with high quality ambulatory care. These indicators have recently been adapted for emergency department (ED) patient presentations. In this study the authors sought to identify opportunities to potentially prevent emergency conditions and to strengthen systems of ambulatory care by analyzing patterns of ED utilization for PQI conditions. METHODS: Using multivariable logistic regression, the authors analyzed the relationship of patient demographics and neighborhood-level socioeconomic indicators with ED utilization for PQI conditions based on ED visits at an urban, academic medical center in 2017. We also used multilevel modeling to assess the contribution of these variables to neighborhood-level variation in the likelihood of an ED visit for a PQI condition. RESULTS: Of the included 98,522 visits, 17.5% were categorized as potentially preventable based on the ED PQI definition. On multivariate analysis, age < 18 years, Black race, and Medicare insurance had the strongest positive associations with PQI visits, with adjusted odds ratios (aOR) of 1.41 (95% confidence interval [CI], 1.29, 1.56), 1.40 (95% CI, 1.22, 1.61), and 1.40 (95% CI, 1.28, 1.54), respectively. All included neighborhood-level socioeconomic variables were significantly associated with PQI visit likelihood on univariable analysis; however; only level of education attainment and private car ownership remained significantly associated in the multivariable model, with aOR of 1.13 (95% CI, 1.10, 1.17) and 0.96 (95% CI, 0.93, 0.99) per quartile increase, respectively. This multilevel model demonstrated significant variation in PQI visit likelihood attributable to neighborhood, with interclass correlation decreasing from 5.92% (95% CI, 5.20, 6.73) in our unadjusted model to 4.12% (95% CI, 3.47, 4.87) in our fully adjusted model and median OR similarly decreasing from 1.54 to 1.43. CONCLUSION: Demographic and local socioeconomic factors were significantly associated with ED utilization for PQI conditions. Future public health efforts can bolster efforts to target underlying social drivers of health and support access to primary care for patients who are Black, Latino, pediatric, or Medicare-dependent to potentially prevent emergency conditions (and the need for emergency care). Further research is needed to explore other factors beyond demographics and socioeconomic characteristics driving spatial variation in ED PQI visit likelihood.

Teledentistry: Dental hygiene students' knowledge, attitudes, and curriculum recommendations.

Purpose: Research has shown an increase in dental hygiene (DH) students' knowledge and attitudes toward teledentistry (TD) after TD training in states with permissive but not restrictive DH scope of practice policies. The purpose of this study was to identify self-reported knowledge and attitudes regarding TD among the DH students at the University of North Carolina (UNC) at Chapel Hill before and after an educational intervention and student recommendations for TD curriculum placement.Methods: A faculty presentation and video demonstration, followed by small group discussions and a large group debriefing session were conducted at the UNC Adams School of Dentistry in March 2019. Participants were invited to complete a survey before and after the educational session. McNemar's matched pair test was used to compare the proportion of the participants' pre- and post-test responses.Results: Survey participants (n=30) included first year and second year DH students. There was significant difference (p<0.001) between pre and post self-reported knowledge of TD as well as a significant difference in participant's response (p= 0.012) about facilitating consultation with health care specialists through TD in NC. There was a significant difference in favorable responses (p=0.0394) that TD could increase reimbursement to dentists to enhance the provision of more services in NC. Students identified didactic courses (43%), simulated cases (47%), and integration into the DH community rotations (66%) as potential ways to incorporate TD into curriculum. Most students (93%) identified DH restricted scope of practice as a barrier to TD implementation in NC.Conclusion: The educational session resulted in increased self-reported knowledge and demonstrated positive attitudes toward the adoption of TD into multiple facets of DH curriculum. A major barrier to its adoption into practice is the DH restricted scope of practice in NC.

Clinical Decision Support Reduces Unnecessary Tetanus Vaccinations in the Emergency Department.

STUDY OBJECTIVE: Tetanus is the most common vaccination given in the emergency department; yet, administrations of tetanus vaccine boosters in the ED may not comply with the US Centers for Disease Control and Prevention's recommended vaccination schedule. We implemented a clinical decision support alert in the electronic health record that warned providers when ordering a tetanus vaccine if a prior one had been given within 10 years and studied its efficacy to reduce potentially unnecessary vaccines in the ED. METHODS: This was a retrospective, quasi-experimental, 1-group, pretest-posttest study in 3 hospital EDs in Boston, MA. We studied adult patients for whom tetanus vaccines were ordered despite a history of vaccination within the prior 10 years. We compared the number of potentially unnecessary tetanus vaccine administrations in a baseline phase (when the clinical decision support alert was not visible) versus an intervention phase. RESULTS: Of eligible patients, 22.1% (95% confidence interval [CI] 21.8% to 22.4%) had prior tetanus vaccines within 5 years, 12.8% (95% CI 12.5% to 13.0%) within 5 to 10 years, 3.8% (95% CI 3.6% to 3.9%) more than 10 years ago, and 61.3% (95% CI 60.9% to 61.7%) had no prior tetanus vaccination documentation. Of 60,983 encounters, 337 met the inclusion criteria. A tetanus vaccination was administered in 91% (95% CI 87% to 96%) of encounters in the baseline phase, compared to 55% (95% CI 47% to 62%) during the intervention. The absolute risk reduction was 36.7% (95% CI 28.0% to 45.4%), and the number of encounters needed to alert to avoid 1 potentially unnecessary tetanus vaccine (number needed to treat) was 2.7 (95% CI 2.2% to 3.6%). For patients with tetanus vaccines within the prior 5 years, the absolute risk reduction was 47.9% (95% CI 35.5 % to 60.3%) and the number needed to treat was 2.1 (95% CI 1.7% to 2.8%). CONCLUSION: A clinical decision support alert that warns ED clinicians that a patient may have an up-to-date tetanus vaccination status reduces potentially unnecessary vaccinations.

The cases not seen: Patterns of emergency department visits and procedures in the era of COVID-19.

OBJECTIVE: Prior data suggest Emergency Department (ED) visits for many emergency conditions decreased during the initial COVID-19 surge. However, the pandemic's impact on the wide range of conditions seen in EDs, and the resources required for treating them, has been less studied. We sought to provide a comprehensive analysis of ED visits and associated resource utilization during the initial COVID-19 surge. METHODS: We performed a retrospective analysis from 5 hospitals in a large health system in Massachusetts, comparing ED encounters from 3/1/2020-4/30/2020 to identical weeks from the prior year. Data collected included demographics, ESI, diagnosis, consultations ordered, bedside procedures, and inpatient procedures within 48 h. We compared raw frequencies between time periods and calculated incidence rate ratios. RESULTS: ED volumes decreased by 30.9% in 2020 compared to 2019. Average acuity of ED presentations increased, while most non-COVID-19 diagnoses decreased. The number and incidence rate of all non-critical care ED procedures decreased, while the occurrence of intubations and central lines increased. Most subspecialty consultations decreased, including to psychiatry, trauma surgery, and cardiology. Most non-elective procedures related to ED encounters also decreased, including craniotomies and appendectomies. CONCLUSION: Our health system experienced decreases in nearly all non-COVID-19 conditions presenting to EDs during the initial phase of the pandemic, including those requiring specialty consultation and urgent inpatient procedures. Findings have implications for both public health and health system planning.

Emergency physicians' active patient queues over the course of a shift.

OBJECTIVES: When emergency physicians see new patients in an ad libitum system, they see fewer patients as the shift progresses. However, it is unclear if this reflects a decreasing workload, as patient assessments often span many hours. We sought to investigate whether the size of a physician's queue of active patients similarly declines over a shift. METHODS: Retrospective cohort study, conducted over two years in three community hospitals in the Northeastern United States, with 8 and 9-h shifts. Timestamps of all encounters were recorded electronically. Generalized estimating equations were constructed to predict the number of active patients a physician concurrently managed per hour. RESULTS: We evaluated 64 physicians over a two-year period, with 9822 physician-shifts. Across all sites, physicians managed an increasing queue of active patients in the first several hours. This queue plateaued in the middle of the shift, declining in the final hours, independently of other factors. Physicians' queues of active patients increased slightly with greater volume and acuity, but did not affect the overall pattern of work. Similarly, working alone or with colleagues had little effect on the number of active patients managed. CONCLUSIONS: Emergency physicians in an ad libitum system tend to see new patients until reaching a stable roster of active patients. This pattern may help explain why physicians see fewer new patients over the course of a shift, should be factored into models of throughput, and suggests new avenues for evaluating relationships between physician workload, patient safety, physicians' well-being, and the quality of care.

Beyond the Maslach burnout inventory: addressing emergency medicine burnout with Maslach's full theory.

Burnout, a psychological syndrome emerging as a prolonged response to chronic interpersonal stressors on the job, remains a substantial problem for emergency physicians, leading to decreased quality of care and attrition from the workforce. The majority of prior work on burnout in emergency medicine has focused on individualized solutions, which have demonstrated modest efficacy for ameliorating burnout. However, recent studies suggest that burnout in medicine is primarily caused by workplace factors (eg, unmanageable workloads, unreasonable time pressures) and therefore requires solutions at an organizational level. In her decades of research across industries, Christina Maslach identified 6 domains of organizations that can either promote engagement or lead to burnout. In this article, we apply Maslach's 6 domains to emergency medicine to provide a systematic framework for alleviating burnout and promoting engagement among emergency physicians. By considering the domains of workload, reward, control, fairness, community, and value congruence, emergency medicine leaders can develop and deploy more effective interventions aimed at improving the experience and longevity of physicians across our specialty.
