High burden of abnormal cervical smears in South African primary health care: health programmes implications

Abstract Cervical cancer is the second most common malignancy among South African women and the load of abnormal cervical smears has clinical, programmatic and policy implications. This cross-sectional study of women who presented for cervical cancer screening aimed to determine the prevalence of abnormal cervical smears and associated factors in primary health care (PHC) facilities in Gauteng—the most densely populated province in South Africa. A questionnaire collected data on socio-demography, tobacco use, sexual behaviours, HIV status, past treatment for sexually transmitted infections (STI) and cervical cancer screening in the past 10 years. Cytology reports were extracted from the laboratory reports. Of 749 participants, most were black (89.7%), aged 30–49 years (62.2%), single (57.5%) and attained high school education (76.8%). About 43.9% were HIV positive with almost all (97.2%) on antiretroviral therapy. Cytology results were available for 612 (81.9%) participants. Of these, 25.8% (159) were abnormal: 13.2% low-grade squamous intraepithelial lesion; 5.7% atypical squamous cells of undetermined significance and 4.9% high-grade squamous intraepithelial lesion. In bivariate and multivariable analysis, abnormal cervical cytology was not associated with any sociodemographic characteristics, HIV status, tobacco use status, sexual behaviours or past treatment for STI. In conclusion, the prevalence of abnormal cervical smears is high across all demographic groups and irrespective of HIV status and highlights the need to increase screening uptake, including advocacy for self-sampling. It also calls for capacity building to allow for the devolution of some downstream clinical care from specialist to district hospitals and large PHC facilities.
