Effects, trends, costs associated with readmission in early-aged patients with suicidal ideation

To examine determinants, trends, and costs associated with 30-day all-cause readmission (R) for suicidal ideation (SI) in early-aged patients.

This was a retrospective cohort study using the 2010-2014 Nationwide Readmissions Database. Discharge records for those aged 5-24 with an SI diagnosis were analyzed. Hierarchical models (HMs) were used to assess factors of R, length of stay (LOS), and total costs of Rs.

There were 197,603 SI index admissions (IAs). Of these, 2% had a R. The annualized trend of R rates for all age groups remained constant. Those aged 13-18 had the highest rate of Rs, while IA and R mean total costs were highest for those aged 5-12 (IA, $4,546-$5,822; R, $5,361-$7,113). The strongest risk factors for increasing R included nonelective admission and private hospital ownership. The strongest risk factors for increasing LOS and cost were major/extreme severity of illness and 30-day all-cause R. The intracluster correlation coefficient for the HMs were 0.06, 0.33, and 0.55 for the R, LOS, and cost model, respectively.

The R rate was highest for those in the 13-18 age group, while the costs were highest for those aged 5-12.
