Impact of primary payer status on outcomes among patients with burn injury: A nationwide analysis

Temporal trends, predictors of blood transfusion and in-hospital outcomes among patients with severe burn injury in the United States-A national database-based analysis

BACKGROUND

Severe burn can be accompanied by life-threatening bleeding on some occasions, thus, blood transfusion is often required in these patients during their hospitalization. Therefore, we aimed to examine temporal trends, predictors, and in-hospital outcomes of blood transfusion in these patients in the United States.

METHODS

The National Inpatient Sample was used to identify severe burn patients between January 2010 and September 2017 in the United States. Trends in the utilization of blood transfusion were analyzed using the Cochran-Armitage trend test. Moreover, propensity score matching (PSM) was employed, and then in-hospital outcomes were compared between these two groups in the matched cohort. Multivariable logistic regressions were further used to validate the results of PSM.

RESULTS

Among 27,260 severe burn patients identified during the study period, 2120 patients (7.18%) received blood transfusion. Blood transfusion rates decreased significantly from 9.52% in 2010 to 5.02% in 2017 (p for trend <.001). In the propensity-matched cohort (2120 pairs with and without transfusion), patients transfused were at increased risk of in-hospital mortality (13.3% vs 8.77%, p < .001), overall postoperative complications (88.3% vs 72.59%, p < .001), longer hospital stays (defined as > median hospital stays = 5 d) (73.8% vs 50.6%, p < .001) and increased overall cost (defined as > median overall costs = 30,746) (81.6% vs 57.3%, p < .001). This was also the case for the multivariable analysis.

CONCLUSIONS

Blood transfusion following severe burn injury may be associated with worse clinical outcomes. The utility for blood transfusion in burn patients warrants further prospective exploration.

The impact of the Affordable Care Act's medicaid expansion on patients admitted for burns: An analysis of national data

INTRODUCTION

The first states began implementing the Medicaid expansion provisions of the Patient Protection and Affordable Care Act (ACA) in 2014. Studies have yet to address its impact on burn patients.

METHODS

Burn patients in geographic regions that expanded Medicaid coverage were compared to patients in regions that did not expand Medicaid before and after implementation of the ACA using bivariate statistics and a difference-in-differences model. A multivariable logistic regression was used to identify factors associated with having Medicaid insurance. The primary outcome of this study was the rate of Medicaid insurance.

RESULTS

Of 25,331 discharges, we found greater increases in Medicaid coverage after the ACA in the Medicaid expander regions (23.4-40.2%) compared to the non-expander regions (18.5-20.1%). The difference-in-differences estimate between the expander and non-expander regions was 0.15 (95% CI: 0.11-0.18, p < 0.001). Patients admitted in expander regions were more likely to be insured by Medicaid (OR 1.57 [95%CI 1.21-2.05]), as were patients of Black race (OR 1.25 [95%CI 1.19-1.32), Hispanic ethnicity (OR 1.29 [95%CI 1.14-1.46]), and female sex (OR 1.59 [95%CI 1.11-2.27]). We also found a significant interaction between time period (pre-ACA/post-ACA) and expander region location (OR 2.10 [95%CI 1.67-2.62]).

CONCLUSIONS

The Medicaid expansion provision of the ACA led to increased Medicaid coverage among burn patients which was significantly higher in areas with widespread implementation of the expansion.

Impact of the affordable care act's medicaid expansion on burn outcomes and disposition

BACKGROUND

We aimed to analyze the impact of the Affordable Care Act's Medicaid Expansion on clinical outcomes and patient disposition after burn injury. We hypothesized that increased insurance coverage results in improved outcomes and higher rates of discharge to inpatient rehabilitation.

METHODS

We reviewed the University of Washington Regional Burn Center registry data for patients admitted from 2011 to 2018. Patients were grouped into two categories: before (2011-2013) and after (2015-2018) Medicaid expansion; we excluded 2014 data to serve as a washout period. Outcomes assessed included length of hospital stay, patient disposition, and mortality. Multivariable logistic and linear regression models with covariates for sex, age, burn size, ethnicity ethnicity, distance from burn center, etiology of burn, and presence of inhalation injury were used to determine the impact of Medicaid expansion on outcomes.

RESULTS

Rates of uninsured patients decreased while Medicaid coverage increased. Despite increased median burn size after Medicaid expansion, inpatient mortality rates did not change, but average acute care length of stay increased. More patients were discharged to rehabilitation centers.

CONCLUSIONS

Our study corroborates prior findings of increased insurance coverage since Medicaid expansion. Increased insurance coverage is associated with higher rates of discharge to inpatient rehabilitation programs after burn injury.

The Impact of the Affordable Care Act on Burn Outcomes

Uninsured and low socioeconomic status patients who suffer burn injuries have disproportionately worse morbidity and mortality. The Affordable Care Act was signed into law with the goal of increasing access to insurance, with Medicaid expansion in January 2014 having the largest impact. To analyze the population-level impact of the Affordable Care Act on burn outcomes, and investigate its impact on identified at-risk subgroups, a retrospective time series of patients was created using data from the Healthcare Cost and Utilization Project National Inpatient Sample database between 2011 and 2016. An interrupted time series analysis was conducted to examine mortality, length of stay, and the probabilities of discharge home, home with home health, and to another facility before and after January 2014. There were no changes in burn mortality detected. There was a statistically significant reduction in the probability of being discharged home (−0.000967, P &lt; .01; 95% confidence interval [CI] −0.0015379 to −0.0003962) or discharged home with home health (−0.000709, P &lt; .01; 95% CI −0.00110 to 0.000317) after 2014. There was an increase in the probability of being discharged to another facility (0.00108, P = .01; 95% CI 0.000282–0.00188). While the enactment of the major provisions of the Affordable Care Act in 2014 was not associated with a change in mortality for burn patients, it was associated with more patients being discharged to a facility: This may represent a significant improvement in access to care and rehabilitation. Future studies will assess the societal and economic impact of improved access to post-discharge facilities and rehabilitation.
