Health Insurance Coverage among Young Adult Survivors of Pediatric Heart Transplantation

Temporal trends in primary payers in pediatric heart transplant and association with long-term survival

BACKGROUND

Pediatric heart transplantation (HT) is resource intensive. In adults, there has been an increase in the proportion of HTs funded by public insurance, with post-HT outcomes inferior to those funded by private sources. Trends in the funding of pediatric HT and outcomes in children have not been described.

METHODS

We queried the United Network for Organ Sharing (UNOS) database for children (<18 years) listed for and undergoing HT between 2004 and 2021. We identified the primary payer at listing, HT, 1 year, and 1-5 years following HT. Trends were analyzed using generalized logit models. Multivariable-extended Cox regression models were used to test the relationship between insurance type at the time of transplant and time to death or re-transplant.

RESULTS

There were 6382 pediatric patients who underwent transplants and had either public or private insurance at the time of transplant. The percentage of patients with public insurance at the time of HT increased over time. Public insurance at the time of HT was associated with an increased risk of death or re-transplant beyond 2 months after HT (adjusted HR at 6 months = 1.43, 95% CI: 1.13-1.81, p = .003; adjusted HR at 9 months = 1.67, 95% CI: 1.17-2.37, p = .004).

CONCLUSION

There has been a statistically significant trend toward increasing public insurance for children awaiting, at the time of, and after HT. Black patients and those with public insurance at HT have worse long-term outcomes. This study highlights ongoing disparities in pediatric HT and the need to focus efforts on achieving equitable outcomes.

The impact of the dependent care provision on individuals with spina bifida transitioning to adulthood

INTRODUCTION

Under the Affordable Care Act, the Dependent Care Provision (DCP) was enacted in 2010 and expanded healthcare coverage for millions of young adults ages 19-25 by allowing them to stay on their parents' insurance until age 26. It is unknown whether the DCP has impacted young adults with SB who are at risk for lapses in insurance coverage as they transition into adult care.

OBJECTIVE

Our aim was to determine the impact of the DCP on access to care (insurance status) and healthcare-quality (hospital admissions for potentially preventable conditions).

METHODS

Using the National Inpatient Sample (an all-payor national dataset of hospital admissions), we analyzed pre/post DCP changes for admissions of SB patients ages 19-25. Our outcomes of interest were rates of insurance coverage and proportion of admissions due to potentially preventable conditions (UTI, pyelonephritis, skin conditions, osteomyelitis, sepsis, and pneumonia). Analysis included a difference-in-differences logistic regression model which compared the pre/post DCP difference (2006-s quarter of 2010 vs. 2011-2013) in patients ages 19-25 to the difference in patients ages 26-32 who were ineligible for the DCP policy.

RESULTS

For admissions of SB patients ages 19-25, the DCP was not associated with improved insurance status compared to admissions ages 26-32 (0% vs. -0.4%, p = 0.10) and rates of private insurance decreased in both age groups, but more so in ages 26-32 (-2.0% vs. -3.9%, p < 0.001). Private insurance rates increased for admissions of white patients ages 19-25 but not for black and Hispanic groups. An increase in overall insurance status was also seen in young adults from high-income zip codes. Admissions for potentially preventable conditions increased in both age groups by a similar degree (+2.6% vs. +2.5%, p = 0.82).

DISCUSSION

Under the Affordable Care Act, the DCP failed to improve rates of private insurance or decrease rates of noninsurance for admissions of young adults with SB. Certain race and socioeconomic groups benefited more from this national healthcare policy. Meanwhile, admissions for potentially preventable conditions are common in spina bifida patients, and increased over the study period, suggesting a need for further investigation into optimizing the delivery of healthcare to this complex patient population.

CONCLUSION

The DCP did not result in improved overall insurance rates or in improved rates of private insurance for admissions of SB patients 18-25 years old.
