Abstract:
BACKGROUND AND OBJECTIVE:Healthcare-associated infections (HAIs) are common and often preventable complications of care, with reduction emphasized in national policy. The Centers for Medicare and Medicaid Services introduced an HAI-focused Hospital Acquired Condition Reduction Program in 2015 to penalize poor-performing hospitals. Standardized infection ratios (SIRs) are used for comparisons between healthcare organizations, though they are not adjusted for socioeconomic risks known to impact infection. The objectives of this study were to assess the relationship between hospital-area deprivation with reported SIRs and reimbursement penalties. METHODS:This was a cohort study using 2018 Hospital Compare, as well as area deprivation data and other hospital characteristics. Multivariable regression models were used to evaluate associations between hospital-area deprivation and SIR reporting as well as payment reduction, adjusting for case mix index and hospital ownership. RESULTS:Of the 2102 unique hospitals in our study, 12.8% reported at least one worse than national benchmark SIR and 23.7% had a payment reduction. After adjustment, there was a 17% increased risk of reporting worse than benchmarked SIRs with quartile increases in deprivation (95% confidence interval: 5%-30%, P = .004). Despite this, there were no significant relationships between reimbursement penalties and ADI (risk ratio: 1.00, 95% confidence interval: 0.997-1.005, P = .567). CONCLUSIONS:This study documented a significant relationship between hospital-area deprivation and the risk of reporting worse than national benchmark SIRs. Though this did not appear to translate to Hospital Acquired Condition Reduction Program penalties in this dataset, it reinforces problems with the current use of SIRs for interhospital comparisons.
