A retrospective review of positive chlamydial cultures in emergency department patients

Abstract

This study evaluated the accuracy of diagnosis and treatment of chlamydial infection based solely on clinical presentation in the emergency department (ED). The signs and symptoms of women with chlamydial infection confirmed by cervical culture were identified and compared between appropriately treated and nontreated groups to determine which clinical features tended to lead to the correct or incorrect diagnosis. The study also determined which signs and symptoms were consistently present in the entire study group. Two hundred thirty-three charts of female ED patients with positive cervical chlamydial cultures were obtained via computerized records from the microbiology lab and reviewed retrospectively. Only 20% of the patients were correctly diagnosed as having a sexually transmitted disease and only 24% were properly treated during their initial ED visit. Although abdominal pain and vaginal discharge were the most frequent symptom and sign, only 70% and 54% of all patients had these clinical manifestations, respectively. Patients with vaginal discharge and cervical motion tenderness were significantly (P < .01) more likely to be treated in the ED. Patients with urinary tract symptoms and pregnancy were significantly (P < .01) less likely to be treated in the ED. Cervical cultures should be performed during all pelvic examinations because of the variability in the clinical presentation of chlamydial infection. A follow-up system must be in place to identify positive cultures and locate patients to ensure appropriate treatment.
