Completitude dos dados de cadastro de portadores de hipertensão arterial e diabetes mellitus registrados no Sistema Hiperdia em um estado do Nordeste do Brasil

Abstract

The scope of this study was to evaluate the accuracy of the data recorded in the Hiperdia system assessed by geographical area, type of field and information consistency between related variables. It involved an observational, descriptive and cross-sectional investigation. The sample of 287 registration forms was randomly and proportionally obtained from the five health regions. Variables relating to blocks of registration and attendance data were selected using the percentage of inaccuracy as an indicator and classification was then made using the Romero and Cunha score (2007). The percentages between the health macro regions was compared using the chi-square test and the completion consistency was assessed using the Kappa coefficient. Of the 32 variables studied, 68.7% revealed good to excellent accuracy. In 62.5% of the variables, the accuracy of the data of the 2nd health macroregion was marked. The percentages of inaccuracy of mandatory data were higher than those for non-mandatory data. Although most of the variables revealed good usage conditions, greater involvement of managers and health professionals in the information production process is required in order to generate more accurate and reliable data.
