GIMENO BENITEZ, Alfredo et al. The Minimum Basic Data Set as an epidemiological vigilance tool for the incidence of diabetes mellitus 1 (DM 1): experience in Extremadura. []. , 12, 32, pp.164-170. ISSN 1695-6141.

The 'gold standard' of knowledge of the epidemiological evolution of the diseases that require hospitalization for diagnosis are the medical records, although the data collection is slow, difficult and time consuming, so if another faster, easier and cheaper source of data was validated, it would be very useful for epidemiological studies. Objectives: To verify The Minimum Basic Data (CMBD) validity as a source of epidemiological vigilance, comparing the CMBD data to the collected information in the medical record. Methodology: The CMBD data compared with the records of the medical records of incident cases of type 1 diabetes mellitus (DM 1) in the population under 15 years of Extremadura during 2003-2007 in a retrospective observational study and descriptive with capture-recapture method. Results: The cases were selected from 208. In 2.40% of cases, the results do not coincide with diabetes coding. 6.73% of cases, the results in the CMBD are coded with other types of diabetes or other pathology. 20.75% of the coded cases as DM 1 in with ketoacidosis doesn't have ketoacidosis in its history, and 69.71% the medical history matches with the CMBD. Discussion: Despite of its limitations, the CMBD has proved to be a valuable source of information. Conclusion: The CMBD serves as a source of information, but not as DM 1 in epidemiological surveillance.
