A 13-Year Longitudinal Analysis of Risk Factors and Clinic Visitation Patterns of Patients with Repeated Gonorrhea

Abstract
A retrospective study of 2498 patients who made multiple visits to a sexually transmitted disease clinic over a 13-year period analyzed risk factors, default patterns, and repeated infections associated with gonococal urethritis. An analysis of visitation patterns found that being young, black, and male and having a history of gonococcal urethritis before visiting the clinic was positively related to the total time a patient remained involved with the clinic. Default rates for all patients increased with successive clinic visits. A focused analysis was carried out on the records of 146 patients who returned to the clinic within 12 months with a second diagnosis of gonococcal urethritis. It was found that this group of "repeaters", who comprised 15% of the total population with gonococcal urethritis, accounted for .apprx. 29% of all diagnoses of this infection over the 13-year study period. Repeaters were found to be more frequently male, black, single, and to be less likely to return for a test-of-cure culture. Longitudinal analysis found that the median time repeaters remained involved with the clinic was .apprx. 130 days. The relatiely brief clinic "half-life" and rapid rates of removal of repeaters are discussed in terms of the development of strain-specific immunity to Neisseria gonorrhoeae in a closed population of patients.
