A new AHRQ Healthcare Cost and Utilization Project (HCUP) Statistical Brief found, in 2018, the in-hospital mortality rate among adults aged 18 to 64 years was twice as high for type 2 diabetes (41 deaths per 10,000 stays) as compared with type 1 (20 deaths per 10,000 stays). Whereas the largest portion of stays involving type 1 diabetes was for patients aged 18-34 years (33 percent), the largest portion of stays involving type 2 diabetes was for patients aged 65-84 years (50 percent). Of stays involving type 1 or type 2 diabetes, 20 and 18 percent, respectively, were for Black patients (vs. 14 percent of stays for patients without diabetes). For adults aged 18-64 years, the in-hospital mortality rate was twice as high for stays for type 2 as those for type 1 diabetes (40.9 vs. 20.4 per 10,000 stays).
This HCUP Statistical Brief – Statistical Brief #279: Diabetes-Related Inpatient Stays, 2018 – presents statistics on nonmaternal inpatient stays involving type 1 or type 2 diabetes among patients aged 1 year or older using weighted estimates from the 2018 National Inpatient Sample (NIS). Patient and hospital characteristics, as well as average length of stay, cost per stay, and in-hospital mortality, are examined by type of diabetes and compared with stays without a diabetes diagnosis. Additionally, reasons for hospitalization and comorbidities among stays involving type 1 or type 2 diabetes are presented.
