    Index to Predict In-hospital Mortality in Older Adults after Non-traumatic Emergency Department Intubations
    (Department of Emergency Medicine, University of California, Irvine School of Medicine, 2017) Ouchi, Kei; Hohmann, Samuel; Goto, Tadahiro; Ueda, Peter; Aaronson, Emily; Pallin, Daniel; Testa Simonson, Marcia; Tulsky, James; Schuur, Jeremiah; Schonberg, Mara
    Introduction: Our goal was to develop and validate an index to predict in-hospital mortality in older adults after non-traumatic emergency department (ED) intubations. Methods: We used Vizient administrative data from hospitalizations of 22,374 adults ≥75 years who underwent non-traumatic ED intubation from 2008–2015 at nearly 300 U.S. hospitals to develop and validate an index to predict in-hospital mortality. We randomly selected one half of participants for the development cohort and one half for the validation cohort. Considering 25 potential predictors, we developed a multivariable logistic regression model using least absolute shrinkage and selection operator method to determine factors associated with in-hospital mortality. We calculated risk scores using points derived from the final model’s beta coefficients. To evaluate calibration and discrimination of the final model, we used Hosmer-Lemeshow chi-square test and receiver-operating characteristic analysis and compared mortality by risk groups in the development and validation cohorts. Results: Death during the index hospitalization occurred in 40% of cases. The final model included six variables: history of myocardial infarction, history of cerebrovascular disease, history of metastatic cancer, age, admission diagnosis of sepsis, and admission diagnosis of stroke/ intracranial hemorrhage. Those with low-risk scores (<6) had 31% risk of in-hospital mortality while those with high-risk scores (>10) had 58% risk of in-hospital mortality. The Hosmer-Lemeshow chi-square of the model was 6.47 (p=0.09), and the c-statistic was 0.62 in the validation cohort. Conclusion: The model may be useful in identifying older adults at high risk of death after ED intubation.

    Morbidity and Mortality Conference in Emergency Medicine Residencies and the Culture of Safety
    (Department of Emergency Medicine, University of California, Irvine School of Medicine, 2015) Aaronson, Emily; Wittels, Kathleen; Nadel, Eric; Schuur, Jeremiah
    Introduction: Morbidity and mortality conferences (M+M) are a traditional part of residency training and mandated by the Accreditation Counsel of Graduate Medical Education. This study’s objective was to determine the goals, structure, and the prevalence of practices that foster strong safety cultures in the M+Ms of U.S. emergency medicine (EM) residency programs. Methods: The authors conducted a national survey of U.S. EM residency program directors. The survey instrument evaluated five domains of M+M (Organization and Infrastructure; Case Finding; Case Selection; Presentation; and Follow up) based on the validated Agency for Healthcare Research & Quality Safety Culture survey. Results: There was an 80% (151/188) response rate. The primary objectives of M+M were discussing adverse outcomes (53/151, 35%), identifying systems errors (47/151, 31%) and identifying cognitive errors (26/151, 17%). Fifty-six percent (84/151) of institutions have anonymous case submission, with 10% (15/151) maintaining complete anonymity during the presentation and 21% (31/151) maintaining partial anonymity. Forty-seven percent (71/151) of programs report a formal process to follow up on systems issues identified at M+M. Forty-four percent (67/151) of programs report regular debriefing with residents who have had their cases presented. Conclusion: The structure and goals of M+Ms in EM residencies vary widely. Many programs lack features of M+M that promote a non-punitive response to error, such as anonymity. Other programs lack features that support strong safety cultures, such as following up on systems issues or reporting back to residents on improvements. Further research is warranted to determine if M+M structure is related to patient safety culture in residency programs.

    Trends in Hospital Admission and Surgical Procedures Following ED visits for Diverticulitis
    (Department of Emergency Medicine, University of California, Irvine School of Medicine, 2016) Greenwood-Ericksen, Margaret B.; Havens, Joaquim; Ma, Jiemin; Weissman, Joel; Schuur, Jeremiah
    Introduction: Diverticulitis is a common diagnosis in the emergency department (ED). Outpatient management of diverticulitis is safe in selected patients, yet the rates of admission and surgical procedures following ED visits for diverticulitis are unknown, as are the predictive patient characteristics. Our goal is to describe trends in admission and surgical procedures following ED visits for diverticulitis, and to determine which patient characteristics predict admission. Methods: : We performed a cross-sectional descriptive analysis using data on ED visits from 2006–2011 to determine change in admission and surgical patterns over time. The Nationwide Emergency Department Sample database, a nationally representative administrative claims dataset, was used to analyze ED visits for diverticulitis. We included patients with a principal diagnosis of diverticulitis (ICD-9 codes 562.11, 562.13). We analyzed the rate of admission and surgery in all admitted patients and in low-risk patients, defined as age <50 with no comorbidities (Elixhauser). We used hierarchical multivariate logistic regression to identify patient characteristics associated with admission for diverticulitis. Results: Fryom 2006 to 2011 ED visits for diverticulitis increased by 21.3% from 238,248 to 302,612, while the admission rate decreased from 55.7% to 48.5% (−7.2%, 95% CI [−7.78 to −6.62]; p<0.001 for trend). The admission rate among low-risk patients decreased from 35.2% in 2006 to 26.8% in 2011 (−8.4%, 95% CI [−9.6 to −7.2]; p<0.001 for trend). Admission for diverticulitis was independently associated with male gender, comorbid illnesses, higher income and commercial health insurance. The surgical rate decreased from 6.5% in 2006 to 4.7% in 2011 (−1.8%, 95% CI [−2.1 to −1.5]; p<0.001 for trend), and among low-risk patients decreased from 4.0% to 2.2% (−1.8%, 95% CI [−4.5 to −1.7]; p<0.001 for trend). Conclusion: From 2006 to 2011 ED visits for diverticulitis increased, while ED admission rates and surgical rates declined, with comorbidity, sociodemographic factors predicting hospitalization. Future work should focus on determining if these differences reflect increased disease prevalence, increased diagnosis, or changes in management.

    Physician Quality Reporting System Program Updates and the Impact on Emergency Medicine Practice
    (Department of Emergency Medicine, University of California, Irvine School of Medicine, 2016) Wiler, Jennifer L.; Granovsky, Michael; Cantrill, Stephen V.; Newell, Richard; Venkatesh, Arjun K.; Schuur, Jeremiah
    In 2007, the Centers for Medicaid and Medicare Services (CMS) created a novel payment program to create incentives for physician’s to focus on quality of care measures and report quality performance for the first time. Initially termed “The Physician Voluntary Reporting Program,” various Congressional actions, including the Tax Relief and Health Care Act of 2006 (TRHCA) and Medicare Improvements for Patients and Providers Act of 2008 (MIPPA) further strengthened and ensconced this program, eventually leading to the quality program termed today as the Physician Quality Reporting System (PQRS). As a result of passage of the Affordable Care Act of 2010, the PQRS program has expanded to include both the “traditional PQRS” reporting program and the newer “Value Modifier” program (VM). For the first time, these programs were designed to include pay-for-performance incentives for all physicians providing care to Medicare beneficiaries and to measure the cost of care. The recent passage of the Medicare Access and Children’s Health Insurance Program (CHIP) Reauthorization Act in March of 2015 includes changes to these payment programs that will have an even more profound impact on emergency care providers. We describe the implications of these important federal policy changes for emergency physicians.

    Emergency department quality and safety indicators in resource-limited settings: an environmental survey
    (Springer Berlin Heidelberg, 2015) Aaronson, Emily; Marsh, Regan; Guha, Moytrayee; Schuur, Jeremiah; Rouhani, Shada
    Background: As global emergency care grows, practical and effective performance measures are needed to ensure high quality care. Our objective was to systematically catalog and classify metrics that have been used to measure the quality of emergency care in resource-limited settings. Methods: We searched MEDLINE, Embase, CINAHL, and the gray literature using standardized terms. The references of included articles were also reviewed. Two researchers screened titles and abstracts for relevance; full text was then reviewed by three researchers. A structured data extraction tool was used to identify and classify metrics into one of six Institute of Medicine (IOM) quality domains (safe, timely, efficient, effective, equitable, patient-centered) and one of three of Donabedian’s structure/process/outcome categories. A fourth expert reviewer blinded to the initial classifications re-classified all indicators, with a weighted kappa of 0.89. Results: A total of 1705 articles were screened, 95 received full text review, and 34 met inclusion criteria. One hundred eighty unique metrics were identified, predominantly process (57 %) and structure measures (27 %); 16 % of metrics were related to outcomes. Most metrics evaluated the effectiveness (52 %) and timeliness (28 %) of care, with few addressing the patient centeredness (11 %), safety (4 %), resource-efficiency (3 %), or equitability (1 %) of care. Conclusions: The published quality metrics in emergency care in resource-limited settings primarily focus on the effectiveness and timeliness of care. As global emergency care is built and strengthened, outcome-based measures and those focused on the safety, efficiency, and equitability of care need to be developed and studied to improve quality of care and resource utilization.

    Estimates of Electronic Medical Records in U.S. Emergency Departments
    (Public Library of Science, 2010) Geisler, Benjamin P.; Schuur, Jeremiah; Pallin, Daniel
    Background: Policymakers advocate universal electronic medical records (EMRs) and propose incentives for “meaningful use” of EMRs. Though emergency departments (EDs) are particularly sensitive to the benefits and unintended consequences of EMR adoption, surveillance has been limited. We analyze data from a nationally representative sample of US EDs to ascertain the adoption of various EMR functionalities. Methodology/Principal: Findings We analyzed data from the National Hospital Ambulatory Medical Care Survey, after pooling data from 2005 and 2006, reporting proportions with 95% confidence intervals (95% CI). In addition to reporting adoption of various EMR functionalities, we used logistic regression to ascertain patient and hospital characteristics predicting “meaningful use,” defined as a “basic” system (managing demographic information, computerized provider order entry, and lab and imaging results). We found that 46% (95% CI 39–53%) of US EDs reported having adopted EMRs. Computerized provider order entry was present in 21% (95% CI 16–27%), and only 15% (95% CI 10–20%) had warnings for drug interactions or contraindications. The “basic” definition of “meaningful use” was met by 17% (95% CI 13–21%) of EDs. Rural EDs were substantially less likely to have a “basic” EMR system than urban EDs (odds ratio 0.19, 95% CI 0.06–0.57, p = 0.003), and Midwestern (odds ratio 0.37, 95% CI 0.16–0.84, p = 0.018) and Southern (odds ratio 0.47, 95% CI 0.26–0.84, p = 0.011) EDs were substantially less likely than Northeastern EDs to have a “basic” system. Conclusions/Significance: EMRs are becoming more prevalent in US EDs, though only a minority use EMRs in a “meaningful” way, no matter how “meaningful” is defined. Rural EDs are less likely to have an EMR than metropolitan EDs, and Midwestern and Southern EDs are less likely to have an EMR than Northeastern EDs. We discuss the nuances of how to define “meaningful use,” and the importance of considering not only adoption, but also full implementation and consequences.

    Variation in the Use of Observation Status Evaluation in Massachusetts Acute Care Hospitals, 2003-2006
    (Springer-Verlag, 2010) Schuur, Jeremiah; Venkatesh, Arjun; Bohan, J.
    Background Observation evaluation is an alternate pathway to inpatient admission following Emergency Department (ED) assessment. Aims We aimed to describe the variation in observation use and charges between acute care hospitals in Massachusetts from 2003 to 2006. Methods Retrospective pilot analysis of hospital administrative data. Patients discharged from a Massachusetts hospital between 2003 and 2006 after an observation visit or inpatient hospitalization for six emergency medical conditions, grouped by the Clinical Classification System (CCS), were included. Patients discharged with a primary obstetric condition were excluded. The primary outcome measure, “Observation Proportion” (pOBS), was the use of observation evaluation relative to inpatient evaluation (pOBS = n Observation/(n Observation + n Inpatient). We calculated pOBS, descriptive statistics of use and charges by the hospital for each condition. Results From 2003 to 2006 the number of observation visits in Massachusetts increased 3.9% [95% confidence interval (CI) 3.8% to 4.0%] from 128,825 to 133,859, while inpatient hospitalization increased 1.29% (95% CI 1.26% to 1.31%) from 832,415 to 843,617. Nonspecific chest pain (CCS 102) was the most frequently observed condition with 85,843 (16.3% of total) observation evaluations. Observation visits for nonspecific chest pain increased 43.5% from 2003 to 2006. Relative observation utilization (pOBS) for nonspecific chest pain ranged from 25% to 95% across hospitals. Wide variation in hospital use of observation and charges was seen for all six emergency medical conditions. Conclusions There was wide variation in use of observation across six common emergency conditions in Massachusetts in this pilot analysis. This variation may have a substantial impact on hospital resource utilization. Further investigation into the patient, provider and hospital-level characteristics that explain the variation in observation use could help improve hospital efficiency.

    Systematic Review of Emergency Department Central Venous and Arterial Catheter Infection
    (Springer-Verlag, 2010) LeMaster, Christopher H.; Agrawal, Ashish T.; Hou, Peter; Schuur, Jeremiah
    Background: There is an extensive critical care literature for central venous catheter and arterial line infection, duration of catheterization, and compliance with infection control procedures. The emergency medicine literature, however, contains very little data on central venous catheters and arterial lines. As emergency medicine practice continues to incorporate greater numbers of critical care procedures such as central venous catheter placement, infection control is becoming a greater issue. Aims: We performed a systematic review of studies reporting baseline data of ED-placed central venous catheters and arterial lines using multiple search methods. Methods: Two reviewers independently assessed included studies using explicit criteria, including the use of EDplaced invasive lines, the presence of central line-associated bloodstream infection, and excluded case reports and review articles. Finding significant heterogeneity among studies, we performed a qualitative assessment. Results: Our search produced 504 abstracts, of which 15 studies were evaluated, and 4 studies were excluded because of quality issues leaving 11 cohort studies. Four studies calculated infection rates, ranging 0–24.1/1,000 catheter-days for central line-associated and 0–32.8/1,000 catheter-days for central line-related bloodstream infection. Average duration of catheterization was 4.9 days (range 1.6–14.1 days), and compliance with infection control procedures was 33–96.5%. The data were too poor to compare emergency department to in-hospital catheter infection rates. Conclusions: The existing data for emergency department placed invasive lines are poor, but suggest they are a source of infection, remain in place for a significant period of time, and that adherence to maximum barrier precautions is poor. Obtaining accurate rates of infection and comparison between emergency department and inpatient lines requires prospective study.
