Results are reported of health services provided for contract and volunteer hospital workers, of participation by hospital employee unions in the development of health and safety programs and of the policies and practices with respect to the health and safety of pregnant hospital employees in 72.4 percent of the 3,687 member hospitals of the American Hospital Association surveyed by questionnaire in 1972. Only 50.6 percent indicated that they had contract workers, a low percentage attributed to a lack of appreciation of the many functions performed in hospitals by contract workers, ranging from security guards to vending machine service people and telephone repairmen. About 70 percent of the hospitals reported that they had volunteer workers. Immunization requirements are the same for contract workers as for hospital employees in 14.4 percent of the hospitals. Immunization requirements for volunteers become similar to those for hospital employees as the number of volunteers increases up to the 100-199 level, but the requirements decrease with 200 or more volunteers. Almost 25 percent of all hospitals provide the same health services for contract workers as for hospital employees, and 30 percent provide the same health services for volunteers. Over 15 percent of the hospitals reported that employee unions participated in the development of health or safety programs. Only about 10 percent reported they had no formal policy with respect to pregnancy. However, less than 40 percent required early reporting of pregnancy, and less than 15 percent reassigned pregnant workers to safer working conditions.
