Checklist for evaluation of the Immunization Information System: development and validation
Abstract
The study aimed to develop and validate the content and appearance of a checklist to evaluate the performance of the Brazilian Immunization Information System in vaccination rooms. It is a methodological study with a quantitative approach, which led to the validation of the content and appearance of the items in a checklist, structured in two dimensions: structure and process. The Delphi technique was used to validate the items according to the criteria of relevance, objectivity and clarity. The content validation index and Cronbach's alpha coefficient were calculated to analyze the internal consistency of the checklist, which consists of 7 items in the structure dimension and 17 in the process dimension, and is subdivided into 3 components: management the immunization information system; registry of the vaccinated and movement of immunobiologicals. Considering the two dimensions, the total content validation rate of the checklist was 89.6%. In the structure dimension, an average content validation index was 89.9; 89.2% was obtained in the processes dimension, and 86.2% in the management component of the Immunization Information System; 92.6% in the registry of vaccinated and 88.9% in the immunobiological movement. The checklist proved to be internally consistent, with a total Cronbach's alpha value of 0.97 and values of 0.86 and 0.97 for the structure and process dimensions, respectively. Regarding the validation of the appearance, the instrument was considered intelligible. The study provides a checklist with valid content and appearance to evaluate the performance of the Brazilian Immunization Information System and supports the supervision and monitoring of the functionalities of this system in the vaccination rooms.
Key words: Immunization program; information systems; validation studies; health evaluation; nursing.
