OBJECTIVES: Identify and describe inpatient hospitalizations associated with type 1 diabetes (T1D) in the Mexican public sector. There is a lack of data on T1D separate from type 2 diabetes (T2D) to inform policy making.

METHODS: Data was collected from the DGIS database (General Direction of Information on Health) on hospitalizations associated with T1D, as codified by the CIE 10 codes E10-E109, between the years 2008-2020. Variables included the number of hospitalizations, duration of stay, and demographic data. Data was analyzed per geography (state), year, institution, and per CIE 10 code.

The average cost of hospitalization was estimated using the unitary cost per day published by the Mexican Social Security Institute (IMSS), in 2022 Mexican pesos.

RESULTS: A total of 99,298 hospitalizations were reported between 2008-2020, with an average of 7,638 per year, a high of 10,545 (2019), and a low of 6,409 (2009). The Secretary of Health and IMSS reported the most cases with 43.4 and 40.8%, respectively. Mexico City reported the most hospitalizations (12.6%), followed by the state of Jalisco (9.2%) and the State of Mexico (6.4%), Sonora (5.3%), and Nuevo Leon (5.2%). The complications associated with most hospitalizations were E101 Ketoacidosis (25.0%) and E105 Peripheral circulatory complications (17.4%). Complications not specified (E106, E107, E108, E109) summed to 44.8% of hospitalizations. A total of 65.9% of hospitalizations were for between 1 (16.1%) and 5 (9.3%) days.

All hospitalizations summed to a total of 567,074 days of inpatient care, for an estimated $6.1 billion MXN in the direct cost of hospitalization.

CONCLUSIONS: Hospitalization of patients for T1D reflect an important clinical and economic challenge for the Mexican public healthcare system. The data suggests that there is an opportunity to strengthen data collection for people with T1D with the objective of strengthening policy and care for this patient group.
