Critical access hospitals: how many rural hospitals will meet the requirements?

Although the Medicare Rural Hospital Flexibility Program (MRHFP), which establishes a new designation for limited-service hospitals called critical access hospitals (CAH), intends to assist small rural hospitals having financial difficulty, it is unclear how many hospitals will qualify for the program. Potential CAHs are identified and the strategic issues that will impact actual participation in the program are discussed. Potential CAHs are identified by applying the legislative criteria for designation to a data set created from both the 1992-1995 Medicare Hospital Cost Report Information System and the 1993 and 1995 Prospective Payment System's Impact files. Descriptive analyses are used to identify potential CAHs by three parameters: distance to nearest hospital, average daily census and operating margin. Results indicate that the majority of potential CAHs have low volume and report poorer operating margins than other rural hospitals. Findings also show that the mileage requirements significantly impact the number of potential CAHs. There is more than a ninefold difference between the 93 hospitals that meet the mileage criterion and the 864 hospitals that might be eligible if certified by the state as "necessary providers," regardless of distance to the nearest hospital. The MRHFP is designed to prevent small, isolated hospitals from closing and thus to ensure continued access to care for rural residents. However, the number of potential CAHs that participate will clearly hinge on the flexibility of the program and the ability of states to determine "necessary providers."
