Integrating COVID-19 Vaccination in Primary Care Service Delivery: Insights From Implementation Research in the Philippines.

BACKGROUND: In 2019, the Philippines enacted a universal health coverage law that aimed to establish an integrated health system centered around robust primary care as a core strategy of its health system reform agenda. Although the COVID-19 pandemic disrupted initial progress in the reform process, it also presented an opportunity to pilot interventions to demonstrate integration in various ways. METHODS: We conducted a participatory implementation research study to integrate selected public health interventions into the implementation of the primary care benefit package funded by public health insurance. The study was conducted from October 2022 to April 2023 in the Province of Iloilo, Philippines. Entry points within the primary care service delivery process were identified, and interventions related to COVID-19 vaccination and family planning were implemented and monitored. We used the RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) framework to organize the results and present the analysis. RESULTS: The intervention showed substantial improvement across the 5 dimensions of the RE-AIM framework, including enhanced access to health care services, as indicated by improvements in primary care patient registration, family planning services, and COVID-19 vaccination processes, as well as an increase in registrations and first patient encounters. These improvements corresponded to sustained primary care facility participation throughout the study period. Additionally, emergent factors that either impeded or facilitated the integration process were identified, providing insights for effectively integrating COVID-19 vaccination within the primary care health system. CONCLUSION: Our study provides evidence of the feasibility of integrating public health interventions into primary care settings. It highlights the potential of using existing primary care service delivery and financing mechanisms as entry points for integration. However, further iteration of the model is required to identify specific conditions for success that can be applied in other contexts and settings.

The role of local health officers in advancing public health and primary care integration: lessons from the ongoing Universal Health Coverage reforms in the Philippines.

The COVID-19 pandemic has highlighted the persistent fragmentation of health systems and has amplified the necessity for integration. This issue is particularly pronounced in decentralise settings, where fragmentation is evident with poor coordination that impedes timely information sharing, efficient resource allocation and effective response to health threats. It is within this context that the Philippine Universal Health Care law introduced reforms focusing on equitable access and resilient health systems through intermunicipal cooperation, enhancing primary care networks and harnessing digital health technologies-efforts that underline the demand for a comprehensively integrated healthcare system. The WHO and the global community have long called for integration as a strategy to optimise healthcare delivery. The authors contend that at the core of health system integration lies the need to synchronise public health and primary care interventions to enhance individual and population health. Drawing lessons from the implementation of a pilot project in the Philippines which demonstrates an integrated approach to delivering COVID-19 vaccination, family planning and primary care services, this paper examines the crucial role of local health officers in the process, offering insights and practical lessons for engaging these key actors to advance health system integration. These lessons may hold relevance for other low-ncome and middle-income economies pursuing similar reforms, providing a path forward towards achieving universal health coverage.
