In Botswana, where human immunodeficiency virus (HIV) prevalence remains high, cervical cancer is the leading cause of cancer deaths in women. Multiple organizations recommend high-risk human papillomavirus (hr-HPV) testing as a screening tool; however, high coverage may not be feasible with provider-collected samples. We conducted the first assessment of self- versus provider-collected samples for hr-HPV testing in HIV-positive women in Botswana and report prevalence of hr-HPV and histological outcomes. We recruited HIV-positive women >= 25 years attending an HIV clinic in Gaborone. Self- and provider-collected samples from participants were tested for hr-HPV using Cepheid GeneXpert. Women testing positive for any hr-HPV returned for colposcopy. We used unweighted kappa statistics to determine hr-HPV agreement. We report that 31 (30\%) of 103 women tested positive for any hr-HPV. The most common genotypes were HPV 31/33/35/52/58. Overall agreement between self- and provider-collected samples for any hr-HPV was 92\% with a kappa of 0.80. Ten of the 30 hr-HPV-positive women attending colposcopy had CIN2+ (33\%). In conclusion, in this HIV-positive population, there was excellent agreement between self and provider samples, and self-sampling may play an important role in screening programs in high HIV burden settings with limited resources like Botswana.
