Managed Medicaid cost savings: the Arizona experience.

This paper reports on estimated cost savings for acute care beneficiaries in the Arizona Health Care Cost Containment System (AHCCCS) over its first nine years of operation, fiscal years 1983-1991. AHCCCS has similar eligibility and service coverage as a traditional Medicaid program has but capitates health plans to provide medical services to beneficiaries. The results indicate that the program yielded $100 million in savings over estimates of what a traditional Medicaid program would have cost in Arizona.

Who seeks HIV testing? The impact of risk, knowledge, and state regulatory policy on the testing decision.

This study examines the determinants of an individual's decision to be tested for HIV infection. Using data from the 1988 AIDS Knowledge and Attitudes Survey we develop and test a conceptual model of the factors that impact the testing decision. We estimate the impact that individuals' risk characteristics, sociodemographic characteristics, knowledge about HIV infection, and access to testing have on their decision to be tested.
