In late 1985, the National Institute of Justice (NIJ) began its first study of Acquired Immune Deficiency Syndrome (AIDS) in correctional facilities. The objective of the study was to report on the incidence and institutional management of AIDS within the federal and state prison systems, as well as in the nation's largest jails. The study was conducted annually from 1985-1990 and biannually thereafter. This collection contains data collected in 1985-1990 and 1992 via a mail questionnaire. Questionnaires were sent each year to the correctional departments of all 50 states, the federal prison system, and 33 to 37 large city and county jail systems. In addition, in 1987-1990, Canadian prison systems were surveyed. A different questionnaire was used in each of the seven years of data collection. However, each questionnaire addressed the same major topics: inmate population, numbers of inmate cases of AIDS and AIDS-Related Complex (ARC), aggregate results of Human Immunodeficiency Virus (HIV) antibody testing programs, and major policies regarding AIDS (training and education, testing, medical and psycho-social services, housing, precautionary measures, confidentiality), as well as associated legal and cost issues. The 1992 questionnaire collected additional information on the prevalence of and policies toward inmates with tuberculosis.
