Can visual cervical screening be sustained in routine health services? Experience from Mali, Africa.

ABSTRACT

OBJECTIVE: To assess the feasibility of sustaining visual cervical screening and treatment services in Mali, and to evaluate their performance and impact in improving the provision of cervical cancer control, following an initial cross-sectional study. DESIGN: Descriptive study. SETTING: Bamako area, Mali. POPULATION Women aged 30-59 years. METHODS: Routine visual screening and treatment services were organised through two hospitals and 14 health centres. Patients with positive visual screening tests underwent colposcopy and/or directed biopsies, and ablative or surgical excision treatment was offered to those with cervical intraepithelial neoplasia (CIN). MAIN OUTCOME MEASURES: Test positivity, detection and treatment rates for CIN and the sustainability of screening services. RESULTS: Of the 14,141 women screened, 1682 (11.9%) were positive and were referred for further investigations and treatment. Over 75% of the screen-positive women underwent colposcopy and/or biopsy. CIN 1 was detected in 383 women, CIN 2 in 88, CIN 3 in 37 and invasive cervical cancer in 497. More than 80% of women with CIN and 35% of those with invasive cancer received treatment. The test performance characteristics and treatment coverage of routine screening were similar to those observed in the preceding cross-sectional study. CONCLUSION: Visual screening and treatment services are sustainable and effective in improving cervical cancer control provision by health services in Bamako, Mali. It is essential to organise and sustain several point-of-care services in order to extend cervical cancer prevention in low-income African countries.
