Background: Thermocoagulation (also known as thermoablation, previously as cold coagulation) is increasingly being adopted as an alternative treatment to cryotherapy within 'screen and treat' cervical screening services using visual inspection with acetic acid (VIA) in resource-constrained settings. This ablative treatment is suitable for low-grade squamous epithelial lesions. Given that much of the current systematic review evidence is drawn from high-income settings, it is critical that the evidence base for use within LMICs is strengthened. Aim: To evaluate the effectiveness of thermo-coagulation in the treatment of VIA-positive lesions within a 'screen and treat' program in Malawi, and its acceptability to clients and providers. Methods: Over the last four years, the Nkhoma Cervical Cancer Screening Program has implemented a 'screen and treat' approach using VIA and treatment using thermocoagulation in a rural district general hospital and associated health centers. Women with VIA-positive lesions are offered treatment with thermocoagulation; treated women are requested to return for review at three- six months, and at one year. Mechanisms to ensure monthly data collection and collation are in place. Semistructured qualitative face-to-face interviews were carried out in English with nineteen providers in nine health centers associated with Nkhoma Hospital: a range of issues were explored, including their experience with use of thermocoagulation. A patient experience questionnaire using validated facial pain scales was developed and translated into Chichewa: women complete this following treatment together with a patient attendant. Results: Between October 2013 and July 2017, over 1650 women have received treatment with thermocoagulation. Of a cohort of 446 treated women who had returned for a 1-year review visit by July 2017, 426 (95.5%) were VIA-negative, i.e., a treatment failure rate of < 5%, comparable with the international literature. Relationship between HIV status, initial VIA positivity, and treatment outcomes, will be presented. Staff reported professional satisfaction in being able to offer treatment consistently to VIA-positive clients, closer to their communities. For some, this was contrasted with previous experience of unavailable cryotherapy resulting in loss to treatment of patients. Over 120 women have completed pain scales questionnaires following treatment with the traditional machine, or with one of the two new hand-held models: their experiences (facial pain scales, and free-text comments) will be reported. Conclusion: In many low-resource settings, VIA-based screening with robust treatment protocols will remain central to cervical cancer control until the promise of HPV vaccination is fully realized. Thermocoagulation is an effective treatment modality, acceptable to clients and patients. Ongoing review of outcomes within and across treatment facilities is critical.
