Abstract

Objective

To estimate differences in the length of stay and costs for comparable hospitalizations of patients with spina bifida (SB) with and without pressure injuries.

Design

Retrospective, cross-sectional, observational study.

Setting

Nationwide Inpatient Sample from years 2010-2014.

Participants

Hospitalizations of patients with SB (N=7776). Hospitalizations among patients with SB and pressure injuries (n=3888) were matched to hospitalizations among patients with SB but without pressure injuries (n=3888).

Interventions

Not applicable.

Main Outcome Measures

Differences in length of stay and total costs between the 2 groups.

Results

After successful matching, multivariate modeling of costs and length of stay on matched sample showed that hospitalizations with pressure injuries had an increased 1.2 inpatient days and excess average costs of $1182 in 2014 dollars.

Conclusions

The estimated average cost of hospitalization increased by 10%, and the estimated average length of stay increased by 24% in the presence of pressure injuries among hospitalized patients with SB, compared with their peers without these injuries. These results highlight the substantial morbidity associated with pressure injuries, which are potentially preventable before or during hospitalizations among persons with SB.
