Assisted partner notification services for patients receiving HIV care and treatment in an HIV clinic in Nairobi, Kenya: a qualitative assessment of barriers and opportunities for scale‐up

aPNS among established HIV patients is associated with different barriers and opportunities than aPNS among newly diagnosed patients, and HCWs should build their capacity to support aPNS in this population. There is a strong need for increased training and sensitization on the use of aPNS in different circumstances and for different clients, taking into consideration factors such as timing of partner notification, characteristics of the relationship and duration of knowledge discordance. The overall success of this intervention among populations living with HIV may rely on customization of services and key messages to meet the patients' specific needs.
