Influence of time-to-diagnosis on time-to-percutaneous coronary intervention for emergency department ST-elevation myocardial infarction patients: Time-to-electrocardiogram matters.

Objectives: Earlier electrocardiogram (ECG) acquisition for ST-elevation myocardial infarction (STEMI) is associated with earlier percutaneous coronary intervention (PCI) and better patient outcomes. However, the exact relationship between timely ECG and timely PCI is unclear. Methods: We quantified the influence of door-to-ECG (D2E) time on ECG-to-PCI balloon (E2B) intervention in this three-year retrospective cohort study, including patients from 10 geographically diverse emergency departments (EDs) co-located with a PCI center. The study included 576 STEMI patients excluding those with a screening ECG before ED arrival or non-diagnostic initial ED ECG. We used a linear mixed-effects model to evaluate D2E's influence on E2B with piecewise linear terms for D2E times associated with time intervals designated as ED intake (0-10 min), triage (11-30 min), and main ED (>30 min). We adjusted for demographic and visit characteristics, past medical history, and included ED location as a random effect. Results: The median E2B interval was longer (76 vs 68 min, p < 0.001) in patients with D2E >10 min than in those with timely D2E. The proportion of patients identified at the intake, triage, and main ED intervals was 65.8%, 24.9%, and 9.7%, respectively. The D2E and E2B association was statistically significant in the triage phase, where a 1-minute change in D2E was associated with a 1.24-minute change in E2B (95% confidence interval [CI]: 0.44-2.05, p = 0.003). Conclusion: Reducing D2E is associated with a shorter E2B. Targeting D2E reduction in patients currently diagnosed during triage (11-30 min) may be the greatest opportunity to improve D2B and could enable 24.9% more ED STEMI patients to achieve timely D2E.

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.

Implementing a COVID-19 Virtual Observation Unit in Emergency Medicine: Frontline Clinician and Staff Experiences.

The COVID-19 pandemic pushed hospitals to deliver care outside of their four walls. To successfully scale virtual care delivery, it is important to understand how its implementation affects frontline workers, including their teamwork and patient-provider interactions. We conducted in-depth interviews of 17 clinicians and staff involved with the COVID-19 Virtual Observation Unit (CVOU) in the emergency department (ED) of an academic hospital. The program leveraged remote patient monitoring and mobile integrated health care. In the CVOU (vs. the ED), participants observed increases in interactions among clinicians and staff, patient participation in care delivery, attention to nonmedical factors, and involvement of coordinators and paramedics in patient care. These changes were associated with unintended, positive consequences for staff, namely, feeling heard, experience of meaningfulness, and positive attitudes toward virtual care. This study advances research on reconfiguration of roles following implementation of new practices using digital tools, virtual work interactions, and at-home care delivery.

Acute home-based care for patients with cancer to avoid, substitute, and follow emergency department visits: a conceptual framework using Porter's Five Forces.

Background: Patients with cancer constitute a large and increasing segment of patients who receive unscheduled hospital-based care due to treatment-related symptoms and disease progression. The initial hospital-based touchpoint for these unscheduled hospitalizations is often the emergency department. Traditional models of emergency department and inpatient hospital-based care are saturated and incapable of scaling to accommodate the future, increased needs projected for this population. New models of care are necessary to address this gap. Acute home-based care is a promising tool potentially providing patient-centric, efficient care to eligible patients. Methods: We applied Porter's Five Forces framework that addresses the bargaining power of buyers and suppliers, threat of substitutes and new entrants, and industry rivalries plus the sixth force of regulation to clarify the factors that will promote or challenge the adoption of a home-based cancer care referral model before or following emergency department visits. Exploring this framework provides insights into the complexities of scaling an acute home-based cancer care model and highlights ways for health systems including hospitals, emergency departments, physician groups, and individual emergency physicians and oncologists to optimize their roles in this emerging model of care. Results: We found that current workforce shortages, as well as workflow, infrastructure, and regulatory complexities, pose major challenges that unless carefully addressed may restrict the growth of acute home-based cancer care. Additional uncertainties persist around appropriate payment models and the competitive landscape. Key promoting factors include the recognized need in the cancer community and among payers for new models to decrease unscheduled hospitalizations and emergency department visits as well as the uptake of home-based and technology-enabled solutions during the COVID-19 pandemic. A better understanding of these forces helps to clarify the risks and opportunities as new entrants build their programs. Conclusions: Acute home-based cancer care is a promising tool to complement traditional outpatient clinics, emergency departments, and inpatient hospital-based models of cancer care. New technologies and policies increasingly enable a broader scope of cancer care in the home setting.

Fallacy of Median Door-to-ECG Time: Hidden Opportunities for STEMI Screening Improvement.

Background ST-segment elevation myocardial infarction (STEMI) guidelines recommend screening arriving emergency department (ED) patients for an early ECG in those with symptoms concerning for myocardial ischemia. Process measures target median door-to-ECG (D2E) time of 10 minutes. Methods and Results This 3-year descriptive retrospective cohort study, including 676 ED-diagnosed patients with STEMI from 10 geographically diverse facilities across the United States, examines an alternative approach to quantifying performance: proportion of patients meeting the goal of D2E≤10 minutes. We also identified characteristics associated with D2E>10 minutes and estimated the proportion of patients with screening ECG occurring during intake, triage, and main ED care periods. We found overall median D2E was 7 minutes (IQR:4-16; range: 0-1407 minutes; range of ED medians: 5-11 minutes). Proportion of patients with D2E>10 minutes was 37.9% (ED range: 21.5%-57.1%). Patients with D2E>10 minutes, compared to those with D2E≤10 minutes, were more likely female (32.8% versus 22.6%, P=0.005), Black (23.4% versus 12.4%, P=0.005), non-English speaking (24.6% versus 19.5%, P=0.032), diabetic (40.2% versus 30.2%, P=0.010), and less frequently reported chest pain (63.3% versus 87.4%, P<0.001). ECGs were performed during ED intake in 62.1% of visits, ED triage in 25.3%, and main ED care in 12.6%. Conclusions Examining D2E>10 minutes can identify opportunities to improve care for more ED patients with STEMI. Our findings suggest sex, race, language, and diabetes are associated with STEMI diagnostic delays. Moving the acquisition of ECGs completed during triage to intake could achieve the D2E≤10 minutes goal for 87.4% of ED patients with STEMI. Sophisticated screening, accounting for differential risk and diversity in STEMI presentations, may further improve timely detection.

Patient perceptions of in-home urgent care via mobile integrated health.

OBJECTIVES: Emergency department (ED) crowding poses a severe public health threat, and identifying acceptable means of treating medical conditions in alternative sites of care is imperative. We compared patients' experiences with in-home urgent care via mobile integrated health (MIH) vs urgent care provided in EDs. STUDY DESIGN: Survey, completed on paper, online, or by telephone. We surveyed all patients who received MIH care for an urgent health problem (n = 443) and consecutive patients who visited EDs for urgent care (n = 1436). METHODS: Study participants were members of a managed care plan who were dually eligible for Medicare and Medicaid, 21 years or older, and treated either by MIH or in an ED for nonemergent conditions around Boston, Massachusetts, between February 2017 and June 2018. The survey assessed patients' perceptions of their urgent care experiences. RESULTS: A total of 206 patients treated by community paramedics and 718 patients treated in EDs completed surveys (estimated 66% and 62% response rates, respectively). Patients treated by MIH perceived higher-quality care, more frequently reporting "excellent" (54.7%) or "very good" (32.4%) care compared with ED patients (40.7% and 24.3%, respectively; P < .0001), and were significantly more likely to report that decisions made about their care were "definitely right" compared with patients treated in the ED (66.1% vs 55.6%; P = .02). CONCLUSIONS: Patients appear satisfied with receiving paramedic-delivered urgent care in their homes rather than EDs, perceiving higher-quality care. This suggests that in-home urgent care via MIH may be acceptable for patients with nonemergent conditions.

Advanced practice providers in academic emergency medicine: A national survey of chairs and program directors.

BACKGROUND: The Society for Academic Emergency Medicine Board of Directors convened a task force to elucidate the current state of workforce, operational, and educational issues being faced by academic medical centers related to advanced practice providers (APPs). The task force surveyed academic emergency department (ED) chairs and residency program directors (PDs). METHODS: The survey was distributed to the Association of Academic Chairs of Emergency Medicine (AACEM)-member chairs and their respective residency PDs in 2021. We surveyed 125 chairs with their self-identified PDs. The survey sampled hiring, state-independent practice laws, scope of practice, teaching and supervision, training opportunities, delegation of procedures between physician learners and APPs, and perceptions of the impact on resident and medical student education. RESULTS: Of the AACEM-member chairs identified, 73% responded and 47% of PDs responded. Most (98%) employ either physician assistants or nurse practitioners. Among responding departments, 86% report APPs working in fast-track settings, 80% work in the main ED, and 54% work in the waiting room. In 44% of departments, APPs and residents evaluate patients concurrently, and 2% of respondents reported that APPs manage high-acuity patients without attending involvement. Two-thirds of chairs believe that APPs contribute positively to the quality of patient care, while 44% believe that APPs contribute to the academic environment. One-third of PDs believe that the presence of APPs interferes with resident education. Although 75% of PDs believe that residents require training to work effectively with APPs in the ED, almost half (49%) report zero hours of training around APP supervision or collaborative skills. CONCLUSIONS: APPs are ubiquitous across academic EDs. Future research is required for academic ED leaders to balance physician and APP deployment across the academic ED within the context of patient care, resident education, institutional resources, professional development opportunities for APP staff, and standardization of APP EM training.

Measuring outcome differences associated with STEMI screening and diagnostic performance: a multicentred retrospective cohort study protocol.

INTRODUCTION: Advances in ST-segment elevation myocardial infarction (STEMI) management have involved improving the clinical processes connecting patients with timely emergency cardiovascular care. Screening upon emergency department (ED) arrival for an early ECG to diagnose STEMI, however, is not optimal for all patients. In addition, the degree to which timely screening and diagnosis are associated with improved time to intervention and postpercutaneous coronary intervention outcomes, under more contemporary practice conditions, is not known. METHODS: We present the methods for a retrospective multicentre cohort study anticipated to include 1220 patients across seven EDs to (1) evaluate the relationship between timely screening and diagnosis with treatment and postintervention clinical outcomes; (2) introduce novel measures for cross-facility performance comparisons of screening and diagnostic care team performance including: door-to-screening, door-to-diagnosis and door-to-catheterisation laboratory arrival times and (3) describe the use of electronic health record data in tandem with an existing disease registry. ETHICS AND DISSEMINATION: The completion of this study will provide critical feedback on the quality of screening and diagnostic performance within the contemporary STEMI care pathway that can be used to (1) improve emergency care delivery for patients with STEMI presenting to the ED, (2) present novel metrics for the comparison of screening and diagnostic care and (3) inform the development of screening and diagnostic support tools that could be translated to other care environments. We will disseminate our results via publication and quality performance data sharing with each site. Institutional ethics review approval was received prior to study initiation.

Attending documentation contribution to billing at an academic ED with an electronic health record.

INTRODUCTION: In emergency medicine (EM), patient care documentation serves many functions, including supporting reimbursement. In addition, many electronic health record systems facilitate automatically populating certain data fields. As a result, in the academic model, the attending's note may now more often recapitulate many of the same elements found in the resident's or physician assistant's (PA) note. We sought to determine the value of additional attending documentation, and how often the attending documentation prevented a downcoding event. METHODS: This retrospective, cross-sectional study was exempted by the Institutional Review Board. We randomly reviewed 10 charts for each attending physician during the study period. Outcome measures included the frequency of prevented downcoding events, and the difference in this incidence between residents and PAs. RESULTS: 530 charts were identified, but 6 were excluded as these patients left without being seen. 524 charts remained, of which 286 (45%) notes were written by residents and 238 (55%) notes were written by PAs. Attending documentation prevented 16 (3%) downcoding events, of which 11 were in patient encounters documented by residents and 5 were in encounters documented by PAs (p=0.057). CONCLUSIONS: In this study of an academic medical center documentation model with an EHR, EM attending documentation of the history of present illness, review of systems, physical exam, and medical decision making portions prevented downcoding in a small number of cases. In addition, there was no significant difference in the incidence of prevented downcoding events between residents and PAs.

Access to In-Network Emergency Physicians and Emergency Departments Within Federally Qualified Health Plans in 2015.

INTRODUCTION: Under regulations established by the Affordable Care Act, insurance plans must meet minimum standards in order to be sold through the federal Marketplace. These standards to become a qualified health plan (QHP) include maintaining a provider network sufficient to assure access to services. However, the complexity of emergency physician (EP) employment practices - in which the EPs frequently serve as independent contractors of emergency departments, independently establish insurance contracts, etc… - and regulations governing insurance repayment may hinder the application of network adequacy standards to emergency medicine. As such, we hypothesized the existence of QHPs without in-network access to EPs. The objective is to identify whether there are QHPs without in-network access to EPs using information available through the federal Marketplace and publicly available provider directories. RESULTS: In a national sample of Marketplace plans, we found that one in five provider networks lacks identifiable in-network EPs. QHPs lacking EPs spanned nearly half (44%) of the 34 states using the federal Marketplace. CONCLUSION: Our data suggest that the present regulatory framework governing network adequacy is not generalizable to emergency care, representing a missed opportunity to protect patient access to in-network physicians. These findings and the current regulations governing insurance payment to EPs dis-incentivize the creation of adequate physician networks, incentivize the practice of balance billing, and shift the cost burden to patients.

Using exhaled carbon monoxide and carboxyhemoglobin to evaluate the effectiveness of a chimney stove model in Peru.

BACKGROUND: Measurement of biological indicators of physiological change may be useful in evaluating the effectiveness of stove models, which are intended to reduce indoor smoke exposure and potential health effects. OBJECTIVES: We examined changes in exhaled carbon monoxide (CO), percentage carboxy-hemoglobin, and total hemoglobin in response to the installation of a chimney stove model by the Juntos National Program in Huayatan, Peru in 2008. METHODS: Biomarkers were measured in a convenience sample comprising 35 women who met requirements for participation, and were measured before and three weeks after installation of a chimney stove. The relationships between exposure to indoor smoke and biomarker measurements were also analyzed using simple linear regression models. RESULTS: Exhaled CO reduced from 6.71 ppm (95% CI 5.84-7.71) to 3.14 ppm (95% CI 2.77-3.66) three weeks after stove installation (P < 0.001) while % COHb reduced from 1.76% (95% CI 1.62-1.91) to 1.18% (95% CI 1.12-1.25; P < 0.001). Changes in exhaled CO and % COHb from pre- to post-chimney stove installation were not correlated with corresponding changes in exposure to CO and PM2.5 even though the exposures also reduced after stove installation. CONCLUSION: Exhaled CO and % COHb both showed improvement with reduction in concentration after the installation of the chimney cook stoves, indicating a positive physiological response subsequent to the intervention.
