| Popis: | STUDY OBJECTIVE The aim of this study was to examine the impact of the ACEP (American College of Emergency Physicians) clinical policy regarding diagnosis of suspected appendicitis on changing practice in the pediatric emergency department (ED) in the absence of a formal departmental protocol. METHODS This was a retrospective chart review in a pediatric ED in which patients aged 2 to 18 years were evaluated for appendicitis via ultrasound, computed tomography (CT), or both, over a 7-year study period. We compared rates of CT utilization in the period before the release of the ACEP clinical policy regarding diagnosis and treatment of appendicitis (2008-2009) and the period after (2010-2014). Other metrics of interest were ultrasound results and physician response to results, as well as surrogate markers for quality of care. RESULTS Seven hundred pediatric ED visits were included, with 200 prepolicy release and 500 postrelease. Computed tomography utilization decreased significantly postpolicy release from 43.5% (95% confidence interval [CI], 36.6%-50.3%) to 22.2% (95% CI, 18.5%-25.8%). The proportion of ultrasounds with indeterminate results also decreased, with 71.5% (95% CI, 65.1%-77.9%) and 55.1% (95% CI, 50.7%-59.5%) in the pre and post groups, respectively. Physicians ordered fewer CTs after indeterminate ultrasounds, decreasing from 63.7% (95% CI, 56.9%-70.5%) to 48.3%% (95% CI, 43.9%-52.7%). CONCLUSIONS After the release of the clinical policy, CT utilization decreased significantly suggesting possible effectiveness of the policy in bringing about change in practice. Subsequently, there was an increase in the definitiveness in the ultrasound results. Physicians also evolved in their response to indeterminate ultrasound results, with fewer CTs ordered reflexively after indeterminate results. |
