Inmates have a right to reasonable medical care and sanitation. Ninety-five per cent of all inmates in Illinois are eventually released. Tuberculosis is a major health problem in many state penal institutions. There is a national trend toward its recognition and correction. Few states, however, have adequate control programs. There is a need for separate sections or hospitals to treat this disease. The eradication and treatment should be relatively easy and simple with administrative and medical cooperation. All personnel (guards, attendants, inmates, etc.) of the Tuberculosis Hospital should be immediately responsible to the executive physician, and indirectly to the lay administrators. The retention and removal of all hospital employees should be at the discretion of the executive physician. At times, it is necessary to have sputum collections, temperatures, etc., certified. At least one registered nurse should be on duty during each shift. Inmate personnel need supervision but give good service and are deserving of extra good time. The planning, preparation and serving of food should be under the guidance of qualified personnel. More efficient guards would lessen breaches of discipline; therefore, higher ratings for hospital guards should be considered. Humane methods of enforcing discipline are indicated and successful. Treatment and public health measures should be the same as in modern non-penal sanatoria. Special psychotics should be treated in the mental division. Forty-three per cent of our patients had collapse therapy, and in 38 per cent of these sputa were converted. Ultra-violet light has been very beneficial in tuberculous adenitis and peritonitis. Employees and inmates of the penal institutions should be tuberculin tested and positive reactors x-rayed. Thereafter, at least yearly examinations (tuberculin and/or x-ray) should be made. Parole board decisions are important. If adequate care is provided, [See Figure in the PDF File] inmates should be treated in prison. If treatment is inadequate, sick parole should be considered. Non-penal hospitalization and/or follow-up care should be a condition of parole. At the Pontiac Branch, 76 per cent of the inmates and 81 per cent of the officers are positive reactors and the morbidity rate of inmates for tuberculosis is 899 per 100,000. More deaths occurred in referrals from, the sick lines than from the tuberculin x-ray group. In the Illinois State Penitentiaries, the known mortality rate of inmates from tuberculosis is 137 per 100,000; the estimated mortality rate is 200 per 100,000. Out-patients should be under central medical supervision regardless of the locale of their incarceration. The Department should use a mobile photo-roentgenographic unit (See Fig. 10 ), central interpretation of x-rays, and standardize treatments and methods of transferring patients. There is need for a national committee of physicians to study the problem of tuberculosis in prisons.
