BackgroundLevels of gender-based violence in Papua New Guinea (PNG) are high; health services for survivors are limited. Evidence from the few existing health services for survivors can inform improvements in care in this and similar settings.MethodsMédecins Sans Frontières supported health services for survivors in Lae, PNG from 2008–2013. Routine monitoring data from August 2010-April 2013 were used to describe patient and service characteristics.Results5,892 individuals received care over 6,860 presentations, the majority self-referred or referred by friends and family. Presentations were attributed to intimate partner violence(62%), non-partner sexual violence(15%), other forms of violence(3%), and past (but not current) violence(21%). 97% were female; an estimated 4.9% (95%CI:4.8–5.0%) of females resident in the catchment area presented to the programme during the 2.8years analysed. Of presentations for non-partner sexual violence, 79% knew their abuser and 50% were children <16 years. 92% of presentations reporting current violence received medical treatment for injuries. The majority of patients who received multiple counselling sessions reported improved functioning and decreased severity of psycho-social complaints.ConclusionsCommunity awareness of the availability of free, best-practice, accessible, confidential medical and counselling services for sexual and gender-based violence in Lae, PNG resulted in many survivors presenting for care. High levels of ongoing intimate partner violence and child sexual abuse by known abusers indicates that alongside comprehensive medical care, access to effective services in non-health sectors such as policing, protection and legal services are needed if survivors are to escape the cycle of violence.
