INTRODUCTION: Data on sexual violence (SV) prevalence in Nigeria is limited; however, 2014 data indicate that 24.8% of females aged 18-24 years experienced SV in childhood and only 3.5% received any form of services. Initiation of post-exposure prophylaxis (PEP) to prevent HIV acquisition following SV is most effective when started immediately and is not recommended after 72 hours. Police stations are often entry points for survivors; however, lengthy processes may result in delays and missed PEP opportunities. Using an ongoing phased approach, we introduced PEP into selected police stations in Nigeria's Federal Capital Territory in order to explore expanding access to time-sensitive HIV prevention within non-health services. METHODS: Our intervention phase consisted of the provision of training of police officers and the provision of PEP starter packs coupled with linkage to referral facilities. During two time periods (pre-intervention: January-March 2023) and (during intervention: July-September 2023), we evaluated routinely reported programme data from 27 U.S. Centers for Disease Control and Prevention-supported health facilities for changes in the provision of SV services and PEP initiation. We used geospatial mapping to assess the proximity of participating health facilities to police stations and to see changes in both SV and PEP service provision. The statistical significance of the difference in PEP uptake proportion during the two periods was determined using the Wilcoxon signed rank test at a 0.05 level of significance. RESULTS: Of the total 27 health facilities, 24 were within a 5-km radius of a participating police station. Total SV service provision increased from 114 cases to 218 cases, representing a 91.2% increase and with most of this increase seen among females. PEP initiation increased by 289.3% at the two time points, with 56 initiations pre-intervention to 218 PEP initiations during the intervention. CONCLUSIONS: Our findings showed promise in increasing immediate access to PEP in non-health services and highlighted the feasibility of police stations and health facilities collaboration to address urgent health needs. There was an overall increase in PEP initiations by referral and non-referral facilities which could be the result of demand creation and increased access at police stations.
