Homeless women experience more severe physical and mental health problems than women in the general population. Under-utilization of health services complicates these health conditions. The study reported here explored how homeless women access health services within the context of shelter living and emerging managed care systems. Informed by grounded theory and dimensional analysis, the investigator conducted in-depth interviews with 19 homeless women, 6 staff from agencies serving homeless women, and 2 community health nurses. Findings revealed that homeless women usually had circuitous rather than direct routes to health services. First, they typically found a social network opportunity structure where brokers could assist them into the health care system. The first tiers of access included a domestic violence shelter, a shelter for single homeless women, and a cafe offering low-cost meals to an inner city homeless population. Even after locating this opportunity structure, the conditions of managed care, with its mechanisms of referral and unfamiliarity with the needs of impoverished women, complicated access. Thus, access requires policies that address not only the availability of health professionals, but also tiers of access that include a social network opportunity structure where women can interact with advocates who broker their entry into the health care system.
