Open-access Immunization Surveillance System in Brazil: Evaluation of the simplicity atribute

ABSTRACT

Despite technological advances in vaccination records, the diversity of Immunization Information Systems poses technical and operational challenges, particularly regarding technological infrastructure and usability. This study, based on the ‘Guidelines for Evaluating Public Health Surveillance Systems’ from the Centers for Disease Control and Prevention, aimed to evaluate the Immunization Surveillance System in Brazil in 2024, with an emphasis on the attribute of simplicity, which encompasses the structure and ease of use of information systems. The following criteria were analyzed: data flow, organizations involved, data transfer and dissemination, integration with other systems, data validation process, and training offered, classified as either simple or complex. The Immunization Surveillance System was classified as complex, with the exception of the data validation process. The diversity of information systems used by different professionals and institutions, both public and private, compromises the continuous flow of data and requires a high degree of interoperability. Training activities are insufficient and not very effective, and the complexity of the Immunization Surveillance System demands technological and operational advances to improve the quality of information.
