The “Digital transformation handbook for primary health care: Optimizing person-centred point of service systems” provides stepwise guidance on how to implement and optimize Person-Centered Point of Service Systems (PCPOSS). The handbook supports two key scenarios: transitioning from paper-only systems and enhancing existing digital solutions to create comprehensive, person-centred, interoperable systems. Aimed at health programme managers and their digital transformation teams, this digital transformation handbook outlines essential steps that include requirements gathering, workflow mapping, creating data dictionaries, and documenting decision-support logic. It emphasizes the importance of involving health workers, as end-users of these digital systems, in the development process.
