Inclusion of the variable “skin color” in the Complementary Statistical Information Health Subsystem of Cuba

Introduction: The inclusion of skin color as a sociodemographic variable in health information systems represents a challenge to strengthening health equity in Cuba. Despite having a universal and free healthcare system, the omission of this variable hinders analytical capabilities and the design of inclusive public policies. Objective: To characterize the status of the inclusion process of the “skin color” variable in Cuba’s Complementary Statistical Information Health Subsystem in 2024. Method: A cross-sectional descriptive study was conducted, combining document review, a focus group with specialists, and surveys of healthcare professionals. A total of 67 SIEC systems were analyzed, assessing primary and secondary records, the categories used, and staff perceptions regarding the inclusion of the variable. Results: The variable is present in only 25% of primary records and absent in all flow forms, preventing its consolidation at higher levels. A lack of standardization in the categories used was identified. Strategic systems were prioritized for initial inclusion, such as Classified patients in primary health care, Notifiable Diseases, and Outpatient Consultations. Conclusions: The study characterized the status of the inclusion of the skin color variable in Cuba’s SIEC health information systems in 2024, revealing limited and non-standardized integration. Effective incorporation requires a gradual and structured process that includes technical redesign, staff training, regulatory adjustments, and continuous monitoring.
