Enablers and Barriers of Follow-Up Care: An Experience From an HPV DNA Detection–Based Cervical Cancer Screening Program in Rural India

Background: Success of a cervical cancer screening program is intrinsically linked with appropriate management of women detected positive on screening tests. While routine screening can be done in any setting, the follow-up care of screen positive women is linked with settings that are equipped with diagnostic and treatment facilities, and trained medical providers. In low resource settings, the major obstacles to deliver follow-up care are lack of adequate healthcare infrastructure and trained service providers at district or subdistrict levels. Aim: To assess feasibility of implementing community based interventions to increase uptake of follow-up care of screen positive women in a HPV detection based screening program conducted by Chittaranjan National Cancer Institute (CNCI), Kolkata. Strategy: A network of key stakeholders including government authorities and civil society organizations was developed to deliver continuum of care at the doorsteps of screen positive women. The infrastructure of government's primary health care delivery system was used to set up temporary clinics at district and subdistrict levels. The clinics were organized on prescheduled dates and times that were convenient to the women. Community health workers (CHWs) were trained in community mobilization strategies to increase uptake of follow-up services. All instruments, equipment and consumables required for providing follow-up services were carried to the clinics in a vehicle. Program: The CHWs played a key role in counseling and recalling the screen positive women. The temporary clinics were arranged in the government primary health centers. A team of trained doctors and paramedics provided the diagnostic and treatment services. Colposcopy was performed on all screen positive women using portable colposcopes and guided biopsies were taken as indicated. Women who were eligible for ablative treatment were counseled and treated in the same sitting. All women were advised yearly follow-up. Outcomes: A total of 43,325 women were screened by HC2 test during July 2010 to March 2015, and 2045 (4.7%) women were detected to be high-risk HPV positive. Compliance to first recall was good with 78.6% (1608/2045) of women undergoing diagnostic evaluation at field clinics. But overall compliance to at least one follow-up visit after 1 year was poor (23.2%). Follow-up compliance rate was higher in women who were diagnosed with CIN1 as compared with those with normal diagnosis ( P < 0.001). What was learned: Diagnostic and treatment services could be effectively organized in the community in convergence with existing healthcare delivery system. High compliance to initial diagnostic evaluation and treatment was achieved by making the services available close to the doorsteps of the women. The reasons for low compliance to yearly follow-up were lack of understanding of future cancer risk, unwilling to undergo speculum examination again, and lack of cooperation of spouse/family.
