Objective

To compare emergency room (ER) and inpatient hospital (IP) use rates for persons with spina bifida (SB) to peers without SB, when transition from pediatric to adult health care is likely to occur; and to analyze those ER and IP rates by age, race, socioeconomic status, gender, and type of residential area.

Design

A retrospective cohort study.

Setting

Secondary data analysis in South Carolina.

Participants

We studied individuals who were between 15 and 24 years old and enrolled in the State Health Plan (SHP) or state Medicaid during the 2000–2010 study period.

Methods

Individuals with SB were identified using ICD-9 billing codes (741.0, 741.9) in SHP, Medicaid, and hospital uniform billing (UB) data. ER and IP encounters were identified using UB data. Multivariable Generalized Estimating Equation (GEE) Poisson models were estimated to compare rates of ER and IP use among the SB group to the comparison group.

Main Outcome Measures

Total ER rate and IP rate, in addition to cause-specific rates for ambulatory care sensitive conditions (ACSC) and other condition categories.

Results

We found higher rates of ER and IP use in persons with SB compared to the control group. Among individuals with SB, young adults (those 20–24 years old) had higher rates of ER use due to all ACSC (P = .023), other ACSC (P = .04), and urinary tract infections (UTI; P = .002) compared to adolescents (those 15–19 years old).

Conclusions

Young adulthood is associated with increased ER use overall, as well as in specific condition categories (most notably UTI) in individuals 15–24 years old with SB. This association may be indicative of changing healthcare access as people with SB move from adolescent to adult health care, and/or physiologic changes during the age range studied.
