RESUMO
OBJECTIVES: To determine if adapting a widely-used triage scale into a computerized algorithm in an electronic health record (EHR) shortens emergency department (ED) triage time. DESIGN: Before-and-after quasi-experimental study. SETTING: Urban, tertiary care hospital ED. PARTICIPANTS: Consecutive adult patient visits between July 2011 and June 2013. INTERVENTION: A step-wise algorithm, based on the Emergency Severity Index (ESI-5) was programmed into the triage module of a commercial EHR. MAIN OUTCOME MEASURES: Duration of triage (triage interval) for all patients and change in percentage of high acuity patients (ESI 1 and 2) completing triage within 15 min, 12 months before-and-after implementation of the algorithm. Multivariable analysis adjusted for confounders; interrupted time series demonstrated effects over time. Secondary outcomes examined quality metrics and patient flow. RESULTS: About 32 546 patient visits before and 33 032 after the intervention were included. Post-intervention patients were slightly older, census was higher and admission rate slightly increased. Median triage interval was 5.92 min (interquartile ranges, IQR 4.2-8.73) before and 2.8 min (IQR 1.88-4.23) after the intervention (P < 0.001). Adjusted mean triage interval decreased 3.4 min (95% CI: -3.6, -3.2). The proportion of high acuity patients completing triage within 15 min increased from 63.9% (95% CI 62.5, 65.2%) to 75.0% (95% CI 73.8, 76.1). Monthly time series demonstrated immediate and sustained improvement following the intervention. Return visits within 72 h and door-to-balloon time were unchanged. Total length of stay was similar. CONCLUSION: The computerized triage scale improved speed of triage, allowing more high acuity patients to be seen within recommended timeframes, without notable impact on quality.

OBJECTIVES: To determine a current infection rate of dog bite wounds and predictors of wounds at risk for infection that may benefit from prophylactic antibiotics. METHODS: A prospective multicentre observational study was conducted over 4.5â years. At the time of treatment Emergency Physicians completed a structured data form evaluating patient, wound and treatment characteristics of patients with dog bite wounds. Patients were followed up at 30â days to assess for infection. Predictor variables were analysed with univariate analysis, using either χ(2), parametric or nonparametric methods where appropriate. Significant variables and those with important interactions on univariate analysis were considered in a logistic regression (LR) analysis. RESULTS: 495 patients with dog bites were enrolled and 345 had complete follow-up. Eighteen patients (5.2%, 95% CI 3.1% to 8.1%) had bites that became infected. On univariate analysis, only puncture wounds were found to be significantly associated with infection RR 2.8 (95% CI 1.2 to 6.9). However, location and wound closure met criteria for entry into the model having important interactions; facial wounds had a higher risk of infection than anticipated but were also more likely to be closed (p < 0.0001). A LR model considering puncture wounds, wound closure and wound location found that puncture wounds (OR 4.1 [95% CI 1.4 to 11.7]) and wound closure (OR 3.1 [95% CI 1.03 to 9.0]) were independent predictors of infection. The incidence of infection in wounds that were not punctured or closed during treatment was only 2.6% (95% CI 0.7% to 6.5%). CONCLUSIONS: Puncture wounds or wounds closed during treatment are dog bite wounds at a high risk of infection and should be considered for treatment with prophylactic antibiotics.

OBJECTIVE: To determine risk factors associated with infection and traumatic lacerations and to see if a relationship exists between infection and time to wound closure after injury. METHODS: Consecutive patients presenting with traumatic lacerations at three diverse emergency departments were prospectively enrolled and 27 variables were collected at the time of treatment. Patients were followed for 30 days to determine the development of a wound infection and desire for scar revision. RESULTS: 2663 patients completed follow-up and 69 (2.6%, 95% CI 2.0% to 3.3%) developed infection. Infected wounds were more likely to receive a worse cosmetic rating and more likely to be considered for scar revision (RR 2.6, 95% CI 1.7 to 3.9). People with diabetes (RR 2.70, 95% CI 1.1 to 6.5), lower extremity lacerations (RR 4.1, 95% CI 2.5 to 6.8), contaminated lacerations (RR 2.0, 95% CI 1.2 to 3.4) and lacerations greater than 5 cm (RR 2.9, 95% CI 1.6 to 5.2) were more likely to develop an infection. There were no differences in the infection rates for lacerations closed before 3% (95% CI 2.3% to 3.8%) or after 1.2% (95% CI 0.03% to 6.4%) 12 h. CONCLUSIONS: Diabetes, wound contamination, length greater than 5 cm and location on the lower extremity are important risk factors for wound infection. Time from injury to wound closure is not as important as previously thought. Improvements in irrigation and decontamination over the past 30 years may have led to this change in outcome.

OBJECTIVES: Patients with psychiatric emergencies often spend excessive time in an emergency department (ED) due to limited inpatient psychiatric bed capacity. The objective was to compare traditional resident consultation with a new model (comanagement) to reduce length of stay (LOS) for patients with psychiatric emergencies. The costs of this model were compared to those of standard care. METHODS: This was a before-and-after study conducted in the ED of an urban academic medical center without an inpatient psychiatry unit from January 1, 2007, through December 31, 2009. Subjects were all adult patients seen by ED clinicians and determined to be a danger to self or others or gravely disabled. At baseline, psychiatry residents evaluated patients and made therapeutic recommendations after consultation with faculty. The comanagement model was fully implemented in September 2008. In this model, psychiatrists directly ordered pharmacotherapy, regularly monitored effects, and intensified efforts toward appropriate disposition. Additionally, increased attending-level involvement expedited focused evaluation and disposition of patients. An interrupted time series analysis was used to study the effects of this intervention on LOS for all psychiatric patients transferred for inpatient psychiatric care. Secondary outcomes included mean number of hours on ambulance diversion per month and the mean number of patients who left without being seen (LWBS) from the ED. RESULTS: A total of 1,884 patient visits were considered. Compared to the preintervention phase, median LOS for patients transferred for inpatient psychiatric care decreased by about 22% (p < 0.0005, 95% confidence interval [CI] = 15% to 28%) in the postintervention phase. Ambulance diversion hours increased by about 40 hours per month (p = 0.008, 95% CI = 11 to 69 hours) and the mean number of patients who LWBS decreased by about 26 per month (p = 0.106; 95% CI = -60 to 5.9 visits per month) in the postintervention phase. CONCLUSIONS: A comanagement model was associated with a marked reduction in the LOS for this patient population.

OBJECTIVES: Patients who leave without being seen (LWBS) can be an indicator of patient satisfaction and quality for emergency departments (ED). The objective of this study was to develop a model to determine factors associated with patients who LWBS. METHODS: A modified case-crossover design to determine the transient effects on the risk of acute events was used. Over a four-month period, time intervals when patients LWBS were matched (within two weeks), according to time of day and day of week, with time periods when patients did not LWBS. Factors considered were percentage of ED bed capacity, acuity of ED patients, length of stay of discharged patients in the ED, patients awaiting an admission bed in the ED, inpatient floor capacity, intensive care unit capacity, and the characteristics of the attending physician in charge. McNemar test, Wilcoxon signed-rank test, and conditional logistic regression analyses were used to determine significant variables. RESULTS: Over the study period, there were 11,652 visits, of which 213 (1.8%) resulted in patients who LWBS. Measures of inpatient capacity were not associated with patients who LWBS and ED capacity was only associated when >100%. This association increased with increasing capacity. Other significant factors were older age (p < 0.01) and completion of an emergency medicine residency (p < 0.01) of the physician in charge. When factors were considered in a multivariate model, ED capacity >140% (odds ratio, 1.96; 95% confidence interval = 1.22 to 3.17) and noncompletion of an emergency medicine residency (odds ratio, 1.85; 95% confidence interval = 1.17 to 2.93) were most important. CONCLUSIONS: ED capacity >100% is associated with patients who LWBS and is most significant at 140% capacity. ED capacity of 100% may not be a sensitive measure for overcrowding. Physician factors, especially emergency medicine training, also appear to be important when using LWBS as a quality indicator.
