For example, the proportions of hospital episodes resulting in readmission within the one-year observation periods were 39.3% pre-PPS and 38.4% post-PPS. The group is not particularly old, with 95% being under 85 years of age, and is predominantly female. Gauging the effects of PPS proved to be challenging. The data set that we assembled for this study provided a basis for addressing analytical dimensions that are not generally available on billing records and hospital discharge abstracts alone (Iezzoni, 1986). However, the increase in six month institutionalization rates suggested that the patients entering nursing homes at discharge were not subsequently regaining the skills needed for independent living. A high proportion (19%) of members of this group had prior nursing home stays.

One study recently published by researchers at the Commission on Professional and Hospital Activities (CPHA) employed data from the CPHA sponsored Professional Activity Study (PAS) to examine changes in pre- and post-PPS differences in utilization and outcomes (DesHarnais, et al., 1987). (Part B payments for evaluation and treatment visits are determined by the, Primary diagnosis determines assignment to one of 535 DRGs. Life table methodology permits the derivation of duration specific schedules of the occurrence of events, such as the probability of a discharge to a SNF after a specific number of days of hospital stay. The data employed in this study were Medicare bills submitted for hospitalization and ambulatory care and for limited intermediate care and skilled nursing facility services, and mortality information. This section discusses the service use patterns of hospital, skilled nursing facility (SNF) and home health agency (HHA) care experienced by the NLTCS chronically disabled community sample between 1982-83 and 1984-85. The computational details of such tests are presented in Manton et al., 1987. While the first three studies examined effects of PPS in multiple hospitals in multiple states, two other studies focused on more circumscribed populations. With a prospective system, hospitals would be at finan-cial risk if resource use exceeded the payment level. Disease severity was defined with the Disease Staging methodology and was used to form a patient classification system based on mortality risk. HOW MANY DAYS DO THEY HELP PER WEEK TOGETHER?

The ASHA Action Center welcomes questions and requests for information from members and non-members. In their analysis of the total Medicare population, Conklin and Houchens (1987) indicated that increases in 30-day mortality after PPS was due exclusively to increased case-mix severity of hospital admission.
