Even though DM was included as a diagnosis on the certificate under any category for 62% of the patients in this cohort, the poor filling of these documents because of the lack of a logic sequence of events leading to the death, or it being included as a secondary cause of death 28%, the number of cases for which this disease was stated as the fundamental cause of death, either on the death certificate or INEC's data, was reduced to 24, meaning an underreporting of more than 50%.If cardiovascular diseases are not considered to be related to DM and are excluded, the underreporting is still high approximately 25%.
Aunque la DM se incluyó como diagnóstico en el 62% en este grupo de diabéticos, el mal llenado de estos sea por falta de una secuencia lógica de los eventos que antecedieron al deceso, o por registrarse como causa secundaria 28%, hizo que solo en 24 casos fuera consignada ésta como causa fundamental de muerte, tanto en el análisis de los certificados originales del registro civil como del INEC. Esto generó un subregistro de más del 50% si se considera que las enfermedades cardiovasculares ECV son causa de la DM; si se considera las ECV como causas no asociadas, el subregistro aún sería alto, alrededor del 25%.
