Patient/family education in childhood cancer care is recognized as one of the most effective strategies for better patient and family outcomes across the cancer childhood continuum, yet health professionals have limited training on the basics of health education. This paper aimed to discuss the evaluation of a health education course that was implemented among health professionals caring for children with cancer in a tertiary hospital in the Philippines. A 10-hour online course on the basics of health education was implemented from November to December 2021. Participants answered a survey that assessed their baseline health practices and a pre- and post-course self-assessment on their confidence to deliver health education. Quantitative data were analyzed using frequency, means, and Wilcoxon signed-rank tests. Content analysis was used to analyze qualitative data. At baseline, education practices were not optimal with 18 (77%) participants implementing an individual approach in education, only 2 (9%) stating that everyone taking care of the child is responsible for education, and 6 (27%) not having a structured evaluation of patient/family understanding of the topic at hand. The mean confidence of participants in delivering health education increased after the training program (P = 0.0007). The course was given high marks indicating that approaches are effective and appropriate. Targeted training should then be continued to increase relevant education competencies of health professionals in childhood cancer care which could increase positive patient and family outcomes.
