These youths have a substantial number of preexisting health problems. In addition, they develop acute problems that are associated with their arrest and with the environment of the correctional facility. The availability of medical services varies by the size of the institution. Correctional facilities generally use one of three models of health care delivery: 1) onsite, comprehensive care; 2) onsite, limited care; and 3) offsite care. Standards for medical services established by the American Medical Association in 1979 were later revised by the National Commission on Correctional Health Care. These standards call for regularly scheduled sick calls, an initial medical screening by qualified health professionals or health-trained staff, a complete health appraisal within the first 7 days of admission, a dental screening within the first 7 days, dental hygiene services within the first 14 days, and ongoing mental health services. Compliance with the standards is voluntary, and many facilities do not meet them. To correct these problems State and County medical societies should become involved in providing adolescent health care in these facilities and should work with corrections officials to discourage inappropriate practices.
