To determine whether a quality assurance (QA) program using digital cervicography improved the performance of a visual inspection with acetic acid (VIA) to detect cervical intraepithelial neoplasia grade 2 or worse (CIN 2+) in HIV-infected women in Johannesburg, South Africa.


Visual inspection with acetic acid was performed among HIV-infected women, aged 18 to 65 years, in Johannesburg, South Africa. Nurses received 2 weeks of training on the VIA procedure. The VIA interpretation was performed in real time. The VIA results were then photographed using a retail available digital camera. A gynecologist and medical officer reviewed the VIA digital images within 2 weeks of the procedure. Colposcopic biopsy was performed on all women with positive VIA and 25% negative VIA results. Sensitivity and specificity of VIA for the detection of CIN 2+ were compared between the nurses and physicians at the beginning and at the end of the study.


Positive VIA results were found in 541 (45%) of the 1,202 participating women. The sensitivity of VIA to predict CIN 2+ was improved from 65% to 75% (p = .001) with the addition of digital cervicography and specialist review. There was no statistical difference in the sensitivity of the VIA readings when comparing the first 600 participants to the final 593 participants between the nurses (p = .613) and physicians (p = .624).


Quality assurance performed by specialists using digital cervicography improved the sensitivity of VIA. There was no difference in sensitivity in interpreting VIA between the beginning and the end of the study. Quality assurance should form a cornerstone of any VIA program to improve sensitivity in detecting CIN 2+ lesions.
