Shrestha SS, et al. - Researchers conducted this study to investigate changes in diabetes-related preventable hospitalization costs and to determine the contribution of each underlying factor (total number of hospitalizations, rate of hospitalization, the number of people with diabetes, mean cost per admission, length of stay, and cost per day) to these changes. Using data from the 2001–2014 US National Inpatient Sample for adults, they estimated the trends in hospitalization costs (2014 USD) in total and by condition (short-term complications, long-term complications, uncontrolled diabetes, and lower-extremity amputation). According to findings, the total cost of diabetes-related preventable hospitalizations increased during 2001–2014, mainly due to an increase in the number of people with diabetes and to the cost per day of hospitalization. The underlying factors identified in the study could lead to efforts that could reduce future costs of hospitalization.
