The deworming program, also known as preventive chemotherapy, is one of the most important strategies in combatting Soil-transmitted Helminthiasis. With more than two decades of implementation, only a few countries have reached the target deworming coverage of 75% by the World Health Organization (WHO). In the Philippines, the national deworming coverage from 2018 to 2022 is still below both the WHO and the Department of Health's target deworming coverage. As a result, there is an increasing prevalence of soil-transmitted helminthiasis among populations in endemic areas in the country including South Cotabato.

The purpose of this qualitative study was to describe the experiences of health workers in the implementation of the STH deworming program in South Cotabato, specifically their lived experiences in implementing the deworming program, the challenges and issues they encountered during the implementation, coping strategies, and their insights about the status of the deworming program in the province and how to improve it.

Seventeen health workers implementing the deworming program in the province of South Cotabato were interviewed through in-depth interviews and focus group discussions. Interviews were conducted online due to mobility restrictions during the pandemic. The transcripts were analyzed using Colaizzi’s descriptive phenomenological method and essential themes were formulated.

Our analysis revealed that health workers’ lived experiences revolve around ensuring the quality implementation of the program such as combatting misconceptions about deworming through house-tohouse visitation and education campaigns, reaching far-flung areas, and ensuring children are in good health condition before taking a deworming medicine. Common challenges experienced by the participants were the misconceptions and disinformation regarding deworming, the limited and difficult access to some areas, problems in logistics, and the limited support of some stakeholders. Moreover, participants cited the importance of good community engagement, active involvement and commitment of stakeholders, providing support to health workers, and robust monitoring and evaluation of the program in improving the implementation of deworming.

In the context of this study, there is still a need to intensify the training for implementers to cater more effectively to the concerns of the people and debunk misconceptions about the program. Utilization of various media for information dissemination, enhancing access to hard-to-reach areas, and strengthening community engagements, particularly with barangay and local government officials are essential to address the gaps in the implementation. There must also be improvements in monitoring and evaluation of the program, and additional support and incentives to healthcare workers to sustain implementations.
