Objective
To determine test characteristics of provider judgment for empiric antibiotic provision to patients undergoing STI testing.
Study design
We conducted a retrospective cross-sectional electronic health record review of all patients aged 13–19 years who had GC and CT testing sent from an urban, academic pediatric ED in 2012. We abstracted data including patient demographics, chief complaint, STI test results, and treatment. We calculated test characteristics comparing clinician judgment for presumptive STI treatment with the reference standard of the actual results of STI testing.
Results
Of 1223 patient visits meeting inclusion criteria, 284 (23.2%) had a positive GC and/or CT test result. Empiric treatment was provided in 615 encounters (50.3%). Provider judgment for presumptive treatment had an overall sensitivity of 67.6% (95%CI 61.8, 73.0) and a specificity of 55% (95%CI 51.7, 58.2) for accurate GC and/or CT detection.
Conclusions
Many adolescents tested for GC and CT receive empiric treatment at the initial ED visit. Provider judgment may lack sufficient sensitivity and specificity for identifying infected patients, resulting in the potential for under-treatment of true disease, overtreatment of uninfected patients, or both.
