Do the factors associated with successful contact tracing of patients withgonorrhoea and chlamydia differ?

Objective: To assess and compare factors which may be associated with succe ssful contact tracing in patients with gonorrhoea and chlamydia. Study design: Prospective observational study of patients attending a genit ourinary medicine clinic with a diagnosis of gonorrhoea or chlamydia. Multi variate analysis model including demographic, socioeconomic, and behavioura l variables. Results: The attendance of at least one sexual contact was associated with naming more contacts for patients with gonorrhoea (OR 1.44, 95% CI 1.04-2.0 1). A history of gonorrhoea was associated with successful contact tracing for patients with chlamydia (OR 1.46, 95% CI 1.12-1.9). Successful contact tracing, as defined by at least one confirmed contact attendance after the index case, was not associated with age, sex, sexual orientation, history o f chlamydia, use of condoms, marital status, ethnicity, or socioeconomic st atus for either gonorrhoea or chlamydia. Conclusions: Differences in the composition of the core groups infected wit h gonorrhoea and chlamydia are not explained by differences in contact trac ing success. In the clinic setting studied, the outcome of contact tracing was not associated with a variety of demographic, socioeconomic, and behavi our factors.
