The COVID-19 pandemic presented strategic opportunities to strengthen national health workforce planning to shape future health care systems that are responsive both during normal times and during crises.n We describe our health workforce planning process based on a cocreation model that built a relationship between researchers and policy makers to coproduce recommendations to strengthen primary care and advance universal health coverage in the Philippines. nWe applied 2 approaches to project the future supply of 10 selected health professions and estimated the demand for primary care services at national and subnational levels; our analysis provided spaces for policy recommendations on issues related to health workforce quantity, skill mix, and distribution.
