Introduction Partner notification (PN) is a key public health intervention aimed at preventing re-infection and controls the spread of sexually transmitted infections (STIs). However, limited research has been conducted to investigate factors associated with PN in Ethiopia.
Methods A nested case-control study was undertaken within a cohort of individuals being treated for STI in public health facilities in Ethiopia. Hierarchical binary logistic regression was used to identify socio-demographic, behavioural and psychosocial factors associated with PN.
Results A total of 250 patients on STI treatment who notified their partners (cases) were compared with 185 patients who did not notify their partners (controls). STI patients were less likely to notify their partner if they were single [AOR=0.33, 95% CI: (0.15–0.73)], in casual partnership [AOR=0.33, 95% C:(0.15–73)], not knowledgeable about partner’s sexual behaviour [AOR=0.43, 95% CI: (0.24–0.77)], poor knowledge of risk sexual behaviour [AOR=0.23, 95% CI: (0.12–0.43)] and if they had no intention to notify partners [AOR=0.19, 95% CI: (0.10–0.36)]. The odds of PN were higher among highly educated respondents [AOR=5.16; 95% CI: (1.83–14.54)].
Conclusion Capturing STI cases through patient referral partner notification is less likely to be successful among patients who are single and in causal relationship.
