Dr. Shapiro is an accomplished health services researcher. His scholarship has largely focused upon access to care and disparities in health. His most prominent work has been the HIV Cost and Service Utilization Study (HCSUS), which enrolled a national probability sample of persons with HIV and has been widely-recognized for affecting policy in HIV care through studies of access, diffusion of innovation, costs and utilization, mental health, drug use, risk behavior, viral resistance, health outcomes, providers of HIV care, and the impact of the Ryan White Care Act on patterns of care for HIV. He also has studied racial/ethnic and socioeconomic influences on patterns of care, the impact of major diseases on disparities in life expectancy, the impact of copayments on access to care, scientific misconduct in investigational drug trials, patterns of scientific authorship and their appropriateness in the biomedical literature, the quality of pharmaceutical advertising, variations in the use of intensive care, attitudes of physicians to the care of persons with HIV, and appropriateness of patterns of laboratory testing in clinical care.
