Changes in Emergency Department Care Intensity from 2007-16: Analysis of the National Hospital Ambulatory Medical Care Survey
Introduction: Emergency departments (ED) in the United States (US) have increasingly taken the central role for the expedited diagnosis and treatment of acute episodic illnesses and exacerbations of chronic diseases, allowing outpatient management to be possible for many conditions that traditionally required hospitalization and inpatient care. The goal of this analysis was to examine the changes in ED care intensity in this context through the changes in ED patient population and ED care provided.Methods: We analyzed the National Hospital Ambulatory Medical Care Survey (NHAMCS) from 2007-2016. Incorporating survey design and weight, we calculated the changes in ED patient characteristics and ED care provided between 2007 and 2016. We also calculated changes in the proportion of visits with low-severity illnesses that may be safely managed at alternative settings. Lastly, we compared ED care received and final ED dispositions by calculating adjusted relative risk (aRR) comparing ED visits in 2007 to 2016, using survey weighted multivariable logistic regression.Results: NHAMCS included 35,490 visits in 2007 and 19,467 visits in 2016, representing 117 million and 146 million ED visits, respectively. Between 2007 and 2016, there was an increase in the proportion of ED patients aged 45-64 (21.0% to 23.6%) and 65-74 (5.9% to 7.5%), while visits with low-severity illnesses decreased from 37.3% to 30.4%. There was a substantial increase in the proportion of Medicaid patients (22.2% to 34.0%) with corresponding decline in the privately insured (36.2% to 28.3%) and the uninsured (15.4% to 8.6%) patients. After adjusting for patient and visit characteristics, there was an increase in the utilization of advanced imaging (aRR 1.29; 95% confidence interval [CI], 1.17-1.41), blood tests (aRR 1.16; 95% CI, 1.10-1.22), urinalysis (aRR 1.22; 95% CI, 1.13-1.31), and visits where the patient received four or more medications (aRR 2.17; 95% CI, 1.88-2.46). Lastly, adjusted hospitalization rates declined (aRR 0.74; 95% CI, 0.64-0.84) while adjusted discharge rates increased (aRR 1.06; 95%CI 1.03-1.08). Conclusion: From 2007 to 2016, ED care intensity appears to have increased modestly, including aging of patient population, increased illness severity, and increased resources utilization. The role of increased care intensity in the decline of ED hospitalization rate requires further study

Estimates of Electronic Medical Records in U.S. Emergency Departments
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

Systematic review of emergency department central venous and arterial catheter infection
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
Variation in the use of observation status evaluation in Massachusetts acute care hospitals, 2003–2006
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

Emergency department quality and safety indicators in resource-limited settings: an environmental survey
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.

Association of Emergency Department Length of Stay and Crowding for Patients with ST-Elevation Myocardial Infarction
Introduction: With the majority of U.S. hospitals not having primary percutaneous coronary intervention
(pPCI) capabilities, the time spent at transferring emergency departments (EDs) is predictive of clinical
outcomes for patients with ST-elevation myocardial infarction (STEMI). Compounding the challenges
of delivering timely emergency care are the known delays caused by ED crowding. However, the
association of ED crowding with timeliness for patients with STEMI is unknown. We sought to examine
the relationship between ED crowding and time spent at transferring EDs for patients with STEMI.
Methods: We analyzed the Centers for Medicare and Medicaid Services (CMS) quality data. The
outcome was time spent at a transferring ED (i.e., door-in-door-out [DIDO]), was CMS measure OP-3b for
hospitals with ≥10 acute myocardial infarction (AMI) cases requiring transfer (i.e., STEMI) annually: Time
to Transfer an AMI Patient for Acute Coronary Intervention. We used four CMS ED timeliness measures
as surrogate measures of ED crowding: admitted length of stay (LOS), discharged LOS, boarding time,
and waiting time. We analyzed bivariate associations between DIDO and ED timeliness measures. We
used a linear multivariable regression to evaluate the contribution of hospital characteristics (academic,
trauma, rural, ED volume) to DIDO.
Results: Data were available for 405 out of 4,129 hospitals for the CMS DIDO measure. These facilities
were primarily non-academic (99.0%), non-trauma centers (65.4%), and in urban locations (68.5%). Median
DIDO was 54.0 minutes (IQR 42.0,68.0). Increased DIDO time was associated with longer admitted
LOS and boarding times. After adjusting for hospital characteristics, a one-minute increase in ED LOS at
transferring facilities was associated with DIDO (coefficient, 0.084 [95% CI [0.049,0.119]]; p<0.001). This
translates into a five-minute increase in DIDO for every one-hour increase in ED LOS for admitted patients.
Conclusion: Among patients with STEMI presenting to U.S. EDs, we found that ED crowding has a
small but operationally insignificant effect on time spent at the transferring ED
