Context
Critical Access Hospitals (CAHs) play a crucial role in the nation’s rural safety net. Current policy efforts have focused primarily on helping these small, isolated hospitals remain financially viable to ensure access for Americans living in rural areas. However, we know little about the quality of care they provide, or the outcomes their patients achieve.
Objective
To examine the quality of care and patient outcomes at CAHs, and to understand why patterns of care might differ for CAHs versus non-CAHs.
Design
Retrospective analysis of national data from Medicare and other sources.
Setting
U.S. hospitals.
Patients
Medicare fee-for-service beneficiaries with acute myocardial infarction (AMI), congestive heart failure (CHF), and pneumonia, discharged in 2008–2009.
Main Outcome Measures
Clinical capabilities, performance on processes of care, and 30-day mortality rates.
Results
Compared to other hospitals, CAHs were less likely to have intensive care units (30.0% versus 74.4%, p<0.001), cardiac catheterization capabilities (0.5% versus 47.7%, p<0.001), and at least basic electronic health records (4.6% versus 9.9%, p<0.001). CAHs had lower performance on process measures than non-CAHs for all three conditions examined (Hospital Quality Alliance summary score for AMI 91.0% versus 97.8%, for CHF, 80.6% versus 93.5%, and for pneumonia 89.3% versus 93.7%, p<0.001 for each). Patients admitted to a CAH had higher 30-day mortality rates for each condition than those admitted to non-CAHs (for AMI, 23.5% versus 16.2%, Odds Ratio (OR) 1.70 (95% confidence interval 1.61, 1.80), p<0.001; for CHF, 13.4% versus 10.9%, OR 1.28 (1.23, 1.32), p<0.001; and for pneumonia 14.1% versus 12.1%, OR 1.20 (1.16, 1.24) p<0.001).
Conclusions
Care in CAHs, compared with non-CAHs, is associated with worse processes of care and higher mortality rates.
