Saydah SH, et al. - Via analyzing data from the US MarketScan claims database, researchers quantified the healthcare services use and medical care costs related to the presence of diabetic ketoacidosis (DKA) at diagnosis of diabetes. The study sample consisted of 4,988 participants (aged 3 to 19 years) insured in private fee-for-service plans and newly diagnosed with diabetes during 2010–2016. Investigators found that 42% of youth had DKA at diabetes diagnosis. Youth with DKA at diagnosis had less health services usage (eg, number of outpatient visits: −1.17) and lower total medical costs (−$635) vs youth without DKA at diagnosis in the 60 days prior to a diabetes diagnosis. Youth with DKA had significantly greater healthcare services use and healthcare costs ($6,522) vs those without DKA in the 60 days after diagnosis.
