BACKGROUND/PURPOSE: We investigated hospitalization rates of patients with type 2 diabetes mellitus (T2DM) and individuals without diabetes mellitus (non-DM) in a disease-specific manner from 2005 to 2014 in Taiwan. METHODS: This population-based study was conducted using data from the National Health Insurance Research Database. We analyzed the hospitalization rates of patients with and without T2DM. We collected up to five diagnostic codes given at discharge for each hospitalization, and the first one was considered the main diagnosis. Odds ratios were determined to assess the risk of hospitalization according to disease-specific classifications in patients with T2DM compared with those without T2DM. RESULTS: The hospitalization rates of non-DM patients was stable from 2005 to 2014. By contrast, the rate of hospitalization among patients with T2DM decreased from 395.4 (per 1000 person-years) in 2005 to 336.9 (per 1000 person-years) in 2014. An increase in hospitalization rates for malignancies and sepsis/infection (other than pneumonia) was observed from 2005 to 2014 in both patients with and without T2DM. Although patients with T2DM had a higher hospitalization risk for all the disease-specific classifications than non-DM patients, this difference in risk decreased from 2005 to 2014 for all diseases except pneumonia. CONCLUSION: Hospitalization rates for malignancies and sepsis/infection (other than pneumonia) continually increased from 2005 to 2014 in Taiwan. Although patients with T2DM had a greater risk of disease-specific hospitalization than those without, this difference in risk decreased from 2005 to 2014 for all diseases except for pneumonia.
