Growth and decline in the supply of providers of Medicare-covered home health services in the 80's: national and regional experience.

Using Health Care Financing Administration (HCFA) data, this study documents national and regional patterns of market entry and exit in the home health industry from 1980 to 1990. Nationally, agency origination rates accelerated during the early 1980's, then dropped abruptly in the second half of the decade. The for-profit sector exhibited the greatest volatility. Of the 3,620 proprietary agencies in existence during the decade, 3,284 (90.7%) were new entrants, and 1,551 exited the market by 1990. Regional differences in growth rates and the timing of market entry are also evident. Both growth and decline in the home health industry appear to be a response to the incentives of legislation implemented during this period.

Medicare-certified home health services: national and regional supply in the 1980s.

The number of Medicare-certified home health agencies nearly doubled from 1980 to 1990. Using Health Care Financing Administration data, this study documented national and regional patterns of entry and exist by Medicare home health providers from 1980 to 1990. Nationally, agency origination rates accelerated during the early 1980s and then dropped abruptly in the second half of the decade. The proprietary sector, accounting for approximately 42% of agencies in existence during the period of the study, exhibited the greatest volatility. Regional differences are also evident. Both expansion and contraction in Medicare home health services appear to be a response to the incentives of legislation implemented during this period.

The development and psychometric evaluation of the Pulmonary Functional Status Scale: an instrument to assess functional status in pulmonary disease.

BACKGROUND: This article describes the development and psychometric evaluation of the Pulmonary Functional Status Scale (PFSS). The PFSS was developed to address the need for a self-administered, disease-specific, functional status outcome measure that was conceptually based, relatively short, and comprehensively assessed the psychosocial domains affected by chronic pulmonary disease. METHODS: Content validity of the PFSS was established by a panel of experts. Construct validity was determined by principal components factor analysis using data from 365 subjects derived from several studies that used the PFSS. The sample was predominantly white (80%), married (36%), and male (56%) with a mean age of 68.1 years, mean forced expiratory volume in one second of 1.18 L and mean forced vital capacity of 2.31 L. Test-retest reliability was evaluated in 17 outpatients with chronic obstructive pulmonary disease. Concurrent validity was assessed by correlating responses on the total PFSS with the Sickness Impact Profile (SIP) score (n = 39), and the 12-minute walk test (n = 104). RESULTS: The factor structure solution used 35 of the 50 submitted items, explained 48.7% of the variance, and yielded three factors: Daily Activities/Social Functioning, Psychological Functioning, and Sexual Functioning. Cronbach's alpha coefficients for the total PFSS was 0.93 and the test-retest correlation coefficient was rho = 0.75 (P = 0.001). The correlation between the total PFSS score and the SIP and 12-minute walk test were r = -0.54 (P < 0.001) and r = 0.62 (P < 0.001), respectively. CONCLUSION: The PFSS has solid psychometric properties that make it acceptable for use in clinical practice as well as research.
