Incremental burden of type 2 diabetes in patients experiencing cardiovascular hospitalizations

AbstractObjective: To evaluate the incremental economic burden of type 2 diabetes in patients experiencing cardiovascular (CV) hospitalizations.Research design and methods: Adults with ≥1 CV hospitalization were identified using a US-based healthcare claims database from 1 July 2011 to 30 June 2014. Outcomes for patients surviving the index hospitalization were compared between patients with vs. without type 2 diabetes (cohorts were identified in the pre-index period). Subsequent CV hospitalizations were evaluated using Cox proportional hazards models. All-cause and CV-related healthcare resource utilization (HCRU) and costs captured on a per-patient per-month (PPPM) basis during a variable follow-up period were evaluated using appropriate multivariable regression models.Results: Of 316,207 patients with ≥1 CV hospitalization, 23% had comorbid type 2 diabetes. The mean age ± SD was 62.6 ± 12.3 years and 64.4% were male. During follow-up, the type 2 diabetes cohort had a 19% higher risk of subsequent CV ho...
