OBJECTIVES: The objective was to explore which @entity1 characteristics are associated with repeat @entity341 ( @entity341 ) visitation within 30  days of @entity341 discharge for @entity1 presenting with @entity490 . METHODS: A retrospective, observational study was conducted at a single, @entity7298 . A consecutive sample of adult @entity1 with a chief complaint of @entity490 from January 2010 through December 2010 who were discharged following @entity341 evaluation were included in the analysis. A logistic regression model was used to determine which @entity1 -level factors, including computed tomography (CT) utilization, were associated with the primary outcome of @entity341 revisit within 30  days. RESULTS: Of 80,619 total @entity341 @entity1 visits during the study period, 3,928 @entity341 discharges with a chief complaint of @entity490 were included. A total of 487 (12.4%) @entity1 revisited the @entity341 within 30  days. No deaths were recorded. CT imaging was associated with a lower 30-day revisit rate (odds ratio [OR]  = 0.69, 95% confidence interval [CI]  =  0.55 to 0.87) after controlling for multiple other @entity1 -level factors associated with revisits. Increasing age (OR  = 1.01, 95% CI  =  1.00 to 1.02), increasing triage @entity158 scores (OR  = 1.13, 95% CI  =  1.08 to 1.18), elevated triage heart rate (OR  = 1.42, 95% CI  =  1.07 to 1.89), low @entity1372 levels (OR  = 1.56, 95% CI  =  1.07 to 2.23), and @entity417 (OR  = 1.42, 95% CI  =  1.04 to 1.95) were all associated with increased rate of return. CONCLUSIONS: Performance of an abdominal CT was associated with fewer 30-day revisits, suggesting that future measures of "imaging appropriateness" and " @entity341 overuse" consider downstream utilization of health care resources in addition to the index visit.
