Palliative care is an essential element of universal health coverage. However, palliative care services, particularly pediatric palliative care (PPC) services, are still inadequately developed in many countries, not least members of the Gulf Cooperation Council (GCC) (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates). Advocating for palliative care services requires data-driven estimates of the number of patients needing these services. To estimate the number of children living with life-threatening illnesses in the GCC countries requiring specialist and/or generalist palliative care service provision. Descriptive analysis of published cross-sectional epidemiological data. Subjects were from general and age-specific populations from individual GCC countries. The quantitative data on child population and mortality were collected from 2019 primary and secondary data sources. The need for PPC was estimated using mortality, incidence, and prevalence data from the Institute for Health Metrics and the Global Cancer Observatory. Our conservative analysis revealed that just under 22,000 children needed PPC in GCC countries in 2019, a minimum of 17.5 for every 10,000 children. There is a significant need for PPC services, suggesting that the medical needs of the pediatric population are currently not being fully met. Nationwide PPC services are essential to improve the quality of life of thousands of children in GCC countries by changing policies, professional education, and providing funding to palliative programs. To our best knowledge, this is the first study to highlight the clear and urgent need for the development of PPC services in the GCC countries.
