Objective: Primary high risk human papilloma virus (hrHPV) testing is recommended as first-line screening for cervical cancer. Testing involves either a clinician-collected or a self-collected cervicovaginal swab. This study examines concordance between methods of collection of primary HPV testing. Methods: Ovid MEDLINE, Ovid Embase, and Cochrane were searched for relevant studies on self-collected and clinician-collected primary HPV testing published before December 31, 2022. English-language studies for primary HPV testing of average-risk patients were included. Studies conducted in screening settings rather than colposcopy clinics, that used standard devices for HPV collection, and that directly compared methods of collection were included. Outcomes were concordance and kappa between paired samples, and rate of HPV detection in self-collected and clinician-collected samples. Results: A total of 2381 studies were screened, of which 228 were included for full-text evaluation. Thirty-six studies, including 23,328 individuals screened, met the inclusion criteria. The rate of HPV detection ranged from 4.7% to 63% for self-collection and from 3.7% to 62% for clinician-collection. The concordance ranged from 78.2% to 96.9%, and kappa had substantial agreement for 26 of the 36 studies and moderate agreement for 7 of the 36 studies. Conclusions: This study directly compares clinician-collected and self-collected primary HPV screening rates. Studies were conducted in methods which are widely reproducible in the primary care setting. Primary HPV self-collection is a reliable and accurate method for cervical cancer screening.
