The results of a study on the health care needs and utilization patterns of Hispanic (primarily Mexican American) families in southeastern Wisconsin are presented in this report. The methodology of the study, which included two surveys in a 9 county area, is described. Findings of the two studies, one focusing on health services utilization by Hispanics and the other focusing on provider resources and services for Hispanic clients, are detailed. For the utilization survey, information is presented on background characteristics, source of health care, health status, dental care, family planning, pregnancy and pre-natal care, mental health, and the health insurance coverage of the survey population. Problems in obtaining health care and services desired by Hispanics are also described. For the provider survey, information is presented on the number of Hispanic clients served, services provided, geographical distance of Hispanic clients from health care providers, availability of bilingual health personnel, barriers to care, and special programs for Hispanic clients. Ways in which health care for Hispanics can be improved are suggested. Appended to the report is a list of pertinent literature reviewed by the surveyors and copies of the survey instruments. (GC)
