BACKGROUND: Previously, analgesics were avoided in suspected @entity698 to avoid masking the diagnosis. We determined use of @entity1337 in @entity1 with @entity698 to determine recent trends over time and explore predictors of use of @entity1337 . METHODS: A retrospective review of the National Hospital Ambulatory Medical Care Survey 2006-2010 was conducted including @entity341 ( @entity341 ) @entity1 with @entity697 (ICD-9-CM 540.xx). The association between demographic and clinical information with @entity341 visit prescription of analgesics/opioids was determined using univariate (  (2)) and multivariate (logistic regression) analyses. RESULTS: There were an estimated 763000 @entity341 @entity1 visits for @entity697 from 2006 to 2010. Mean age was 32, 74% were under age 19, 69% were male. Sixty-four percent of @entity1 received any @entity1337 in the @entity341 and 58% received an opioid; use of analgesics did not change over time. Of all @entity1 , 68% had computed tomographic (CT) imaging. There was a positive trend in analgesic use with increasing @entity158 (27% for no @entity158 to 71% for severe @entity158 , P = .08); a similar trend was seen for opioids but was not significant (P = .12). Analgesic use was lower for elderly (age >65) @entity1 (odds ratio [OR] 0.09, 95% confidence interval [CI] 0.01-0.56) and private insurance (OR 0.14, 95% CI 0.05-0.43), and higher for @entity1 with CT scans (OR 3.73, 95% CI 1.61-8.66). @entity158 severity was not associated with administration of analgesics after controlling for other factors. CONCLUSIONS: Use of @entity1337 and opioids @entity1337 has remained stable over time. Factors associated with prescription of any @entity1337 and opioids were older age and payment source. Use of CT was associated with prescription of analgesics.
