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.

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.

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.

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 = À60 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.ACADEMIC EMERGENCY MEDICINE 2013; 20:338-343
