Hospital and ED charges for spina bifida care in the United States between 2006 and 2014: Over $2 billion annually.

Abstract Background More children with spina bifida (SB) are surviving into adulthood. Unfortunately, little data exist regarding the economic implications of modern SB care. Objective We examined economic data from two national databases to estimate the annual nationwide hospital and emergency charges of SB from 2006–14. Methods We analyzed the 2006–2014 Nationwide Inpatient Sample (NIS) and Nationwide Emergency Department Sample (NEDS). SB patients were defined using ICD-9-CM codes. Demographic and charge data were obtained from each database. Multiple imputation was used to estimate missing data (1.6% for NIS and 22% in NEDS). The principal outcomes were mean, median, and total charges for encounters each year. Results There were 725,646 encounters for individuals with SB between 2006 and 2014. The average age of captured SB patients who were admitted to a hospital or seen in an ER was 29 years. In 2014, the median charge for inpatient encounters was $31,071 (IQR: $15,947, $63,063) and for ER encounters was $2407.02 (IQR: $1321.91, $4211.35). In total, the sum of charges from all SB-related admissions in 2014 was $1,862,016,217 (95% CI: $1.69 billion, $2.03 billion), while the sum of charges of all SB-related ER encounters in 2014 was $176,843,522 (95% CI: $158 million, $196 million). There was a steady increase in charges over the study period. Conclusion Charges for SB-related inpatient and emergency care in the US in 2014 was in excess of $2 billion in contrast to $1.2 billion in 2006, after adjusting for inflation; this is an impressively high figure for a relatively small number of patients.
