29Background: In South Africa, utilization of patient-initiated partner-notification (PN) using referral-slip in 30 the management of sexually transmitted infections (STIs) is limited and only a limited number of sexual 31 partners are ever notified. The study assessed the use of patient-initiated PN method using notification and 32 referral slips and measured the level of acceptability of provider-initiated PN using short-message-service 33 (SMS) to personal mobile phones of sexual partners.
34Methods: A quantitative survey using anonymous structured self-administered and researcher 35 assisted questionnaires was conducted among minibus taxi drivers in the nine major taxi ranks in
36Gauteng province, South Africa. 37 Results: The sample consisted of 722 minibus taxi drivers with a mean age of 37.2 years old, 284 (59.5%) 38 had multiple sexual partners, 368 (52.2%) did not use a condom during last sexual act, 286 (42.8%) 39 reported inconsistent use of condoms, and 459 (65%) tested for HIV in the past 12 months. Majority 40 (n=709, 98.2%) understood the importance of PN once diagnosed with STI, but would prefer delivering PN 41 referral slip (n=670, 93.2%) over telling a partner face to face if they themselves were diagnosed with STI. 42 Acceptability of provider-initiated PN using SMS was 452 (62.7%) and associated with history of HIV 43 testing in the past year (OR=1.72, p=0.002, CI: 1.21-2.45). The perceived use of PN referral-slip from 44 sexual partner to seek treatment was 91.8% (n=659). About a third (n=234, 32.5%) were not in favor of 45 provider-initiated PN by SMS and preferred telling partners face to face. 46 Conclusion: There were contrasting findings on the acceptability and utilization of existing patient-initiated 47 PN and the proposed PN using SMS from health providers. The preference of delivering PN referral slip to 48 sexual partner over face-to-face PN renders communicating about STIs the responsibility of health 49 providers. Therefore, they have an opportunity to provide patients with options to choose a PN method that 50 is best suited to their relationships and circumstances and modify PN messages to encourage partners to use 51 the different PN to prevent STIs. 3 52 53 Keywords: partner notification, sexually transmitted infections, patient initiated, STI prevention 54 and control, taxi industry, key populations, risky sexual behavior, short-message-service. 55 4 56 Introduction 57 South Africa's burden of disease due to sexually transmitted infections (STIs) is currently one of 58 the largest in the world and this is true for all STIs, including HIV and human papilloma virus [1]. 59 The significantly high prevalence of sexually transmitted infections (STIs) in Sub-Saharan Africa 60 poses a threat because of the increased risk of HIV transmission [2]. In the African region, among 61 the population group of 15 -49 year of age, STI prevalence and incidence for four curable STIs 62 (chlamydia, gonorrhea, syphilis and trichomonas) was 19.4% and 24.1% [3-5]. The prevalence of 63 syphilis amo...
