“…For example, 80% of users are minority people, virtually all are in poverty or near poor, and the vast majority are women and young children (Department of Health and Human Services, 1980). Such improvements in access have reduced the use of costly emergency rooms (Gold andRosenberg, 1974 Hochheiser, Woodward, andChamey, 1971;Sussman et al, 1979;Moore and Bonanno, 1974) and increased the use of preventive services (Gorman andNelson, 1974 Hershey andMoore, 1975;Kent and Smith, 1967;Milio, 1970). Improvements in child health also have been documented, especially in infant mortality and infectious diseases (Davis and Schoen, 1977;Gold andRosenberg, 1974 Vaughan, 1968;Chabot, 1971;Gordis, 1973;Westermeyer, Framer, and Smelker, 1976).…”
