Patients With Spina Bifida Have Longer Length of Hospital Stay: Statewide Health Care Utilization in California From 1995 to 2017.

ABSTRACT

INTRODUCTION: Our goal was to better understand the health care utilization of patients with spina bifida (SB) by evaluating length of hospital stay (LOS) as well as identifying what characteristics within the SB population are contributing to shorter or longer LOS. METHODS: By querying the Department of Health Care Access and Information database of all encounters at California-licensed hospitals from January 1995 through December 2017, this study analyzed LOS as a measure of health care utilization. Patients with SB were identified using the International Classification of Diseases-9 and -10 coding system, and the data collected for both SB and control cohorts were compared using linear and logistic regression models. RESULTS: Patients with SB spent a mean LOS of 7.3 days compared to 4.7 days among the control cohort (P < .001). In multivariable analysis, SB was found to be an independent predictor of longer LOS. Within the SB encounters, increasing comorbidities and nonprivate insurance were associated with longer LOS, while being female and Hispanic were associated with a shorter LOS. CONCLUSIONS: SB is an independent predictor of longer LOS when compared to the control cohort. These findings highlight the importance of understanding the preventive health care access and needs of the vulnerable SB population to decrease hospital utilization rates.
