RESUMO

Introduction: Usability is a quality attribute that can evaluate the ease of use of user interfaces, based on standards called usability heuristics. Objective: To evaluate the usability components of the Brazilian Immunization Information System (IIS), focusing on the users and their interaction and agility with the interfaces. Materials and Methods: It was a concomitant and convergent mixed-method study that used a cross-sectional design for the quantitative approach and the indirect method of heuristic evaluation for the qualitative approach. Participants were 137 nursing professionals working in vaccination rooms, who completed a structured questionnaire on standards of usability quality, and 4 specialists in information technology, who used a semistructured form to carry out a software inspection. Descriptive and inferential statistics and the heuristic inspection were used for the analyses. Results: The evaluation resulted in 10 violated heuristics and identified 14 usability problems on the 68 screens of the IIS. The system presented simple usability problems (grade 2 severity), which can be repaired, with a low correction priority. The heuristics best evaluated were error prevention (3.03 ± 0.54) and help and documentation (3.00 ± 0.68); and the worst evaluated was visibility of system status, with a mean of 2.62 ± 0.55. Professionals with a technical education level presented a higher score on the scales for the recognition rather than recall heuristic when compared with the nurses (2.77 ± 0.49 vs. 3.67 ± 0.66, p = 0.003). Conclusion: The system provides easy access for users, however, has weaknesses in its ability to allow the users to easily achieve their goals of interaction with the interface.

RESUMO

OBJECTIVE: develop and evaluate a vaccine application for mobile devices, with update integrated with the National Immunization Program Information System, for care in vaccination rooms. METHOD: methodological research based on the Pressman System Development Life Cycle theory developed in three stages: integrative literature review, computational development, and application evaluation. The product was evaluated as to satisfaction, using a validated questionnaire, and as to usability by the System Usability Scale. RESULTS: the application functionalities were based on the survey of technological Innovations on immunization, published in the scientific literature. It displays user vaccines directly from the National Immunization Program Information System, notifies about upcoming vaccines, and enables the inclusion of vaccine cards of dependents. The evaluation resulted in users' mean score of 90.5 ± 11.1 and health professionals' mean score of 84.2 ± 19.4. CONCLUSION: the application is a technological tool with potential to improve the work process in vaccination rooms and to reach the goals of vaccine coverage. It synchronizes data with the National Immunization Program Information System, thus enabling the maintenance of people's vaccination history.
