Abstract

Background: Individuals with congenital heart defects (CHDs) have high hospital resource use. We sought to identify factors associated with hospital costs and multiple hospitalizations among individuals with CHDs.

Methods: Data from the 2006 to 2011 Healthcare Cost and Utilization Project Arkansas State Inpatient Databases were linked across encrypted patient identifiers to develop a cohort of Arkansas residents aged 1 to 64 years who were hospitalized at least once with a CHD during this time period. Infants were excluded because patient identifiers were missing for 18 to 52% each year. CHDs were identified using principal and secondary International Classification of Diseases, Ninth Revision, Clinical Modification diagnoses codes. All hospitalizations of individuals ever admitted with a CHD were included. Mean and median patient-level costs were estimated; the association of hospital costs and patient readmissions were examined with linear and logistic regression.

Results: There were 1,185,868 inpatient hospitalizations of Arkansas residents aged 1 to 64 years between 2006 and 2011; these were accrued by 603,925 patients. Of those, 2542 patients (0.42%) had at least one hospitalization with a CHD diagnosis. Total costs for these 2542 patients were $126,999,837 and they accumulated 7898 hospitalizations. Factors associated with increased costs included patient age, CHD type, cardiac procedures, and comorbidities. Factors associated with hospital readmission within 1 year included age, CHD type, expected payer, and comorbidities.

Conclusion: Individuals with CHDs in Arkansas experience variation in hospital use and costs by patient characteristics. Future research should investigate factors associated with readmissions, cardiac procedures, and comorbidities, as these are strongly associated with hospital costs.
