Competing priorities as a barrier to medical care among homeless adults in Los Angeles.

OBJECTIVES The role of competing priorities as a barrier to the utilization of physical health services was assessed in a subset (n = 363) of a probability sample of homeless adults in Los Angeles. METHODS Unadjusted odds of four measures of health services utilization were calculated for those with frequent difficulty in meeting their subsistence needs. These odds were then adjusted for a range of characteristics assumed to affect the utilization of health services among the homeless. RESULTS Before and after adjustment, those with frequent subsistence difficulty were less likely to have a regular source of care (odds ratio [OR] = 0.30, 95% confidence interval [CI] = 0.16, 0.53) and more likely to have gone without needed medical care (OR = 1.77, 95% CI = 1.04, 3.00). Subsistence difficulty had no impact on the likelihood of having an outpatient visit or having been hospitalized. Conclusions remained the same after adjustment. CONCLUSIONS Frequent subsistence difficulty appears to be an important nonfinancial barrier to the utilization of health services perceived as discretionary among homeless adults.

Antecedents of physical and sexual victimization among homeless women: a comparison to homeless men.

Homeless women experience extensive health risks including physical and sexual victimization. Few studies that have gathered information on homeless persons have reported results separately for women or have compared them directly with men. Research that both investigates antecedents of victimization among homeless women and compares them to those for men is necessary to determine whether prevention efforts must be different for each group. We investigated potential antecedents of recent (past 30 days) physical and sexual victimization in a probability sample of 394 homeless women and compared findings to those for 1159 homeless men. As hypothesized, mental disorder, substance dependence, and engaging in economic survival strategies significantly predicted victimization among homeless women. With few dissimilarities, these characteristics also predicted victimization among homeless men. Although differences in the needs and experiences of homeless women and men must be recognized, both women and men require assistance to establish and maintain safe residences, treatment of any substance use and mental disorder, and alternatives to economic survival strategies that place them at risk for victimization.

Determinants of Regular Source of Care Among Homeless Adults in Los Angeles

OBJECTIVES The authors explore the determinants of having a regular source of care in a community-based probability sample of homeless adults in Los Angeles. Results from this study should be more representative than those from previous studies of the homeless that are clinic- or shelter-based. In addition to those factors found to be barriers to regular sources of care in the general population, we hypothesized that psychosocial characteristics of the homeless and the homeless lifestyle would negatively impact their likelihood of having a regular source of care. METHODS The authors conducted a multiple logistic regression to predict regular source of care among the homeless, using an adaptation of the Behavioral Model of health services utilization as an analytic framework. RESULTS Fifty-seven percent of the sample reported that they had a regular source of care. Of those with a source of care, 30% reported a hospital outpatient department; 25% reported a community or homeless clinic; 23% reported a hospital emergency room; 14% reported a government clinic; and 9% reported a private physicians office as their source of care. Some factors found to be barriers to having a regular source of care in the general population (male, Hispanic, young age) also were barriers among homeless adults. Additional barriers in this sample included homelessness-related characteristics such as competing needs, long-term homelessness, and social isolation. Chronic mental illness and chronic substance dependence were not related to having a source of care among the homeless. Characteristics that increased the likelihood of having a regular source of care in the general population (poor health status, Medicaid) were not related to having a regular source of care among the homeless. CONCLUSIONS In a context of limited resources, the distribution of regular source of care among the homeless appears to be highly inequitable. Although some of the characteristics identifying those with a regular source of care suggest differential patterns of behavior across subgroups, others suggest differential advantage in access to care and a lack of fit between the needs of the homeless and the organization of health services.

Health Care for Homeless Women

AbstractOBJECTIVE: Homelessness is a significant and growing problem in the United States. Women and families are the fastest growing segments of the homeless population. Homelessness increases the risk of having health problems and encountering barriers to care. This study determines how much perceived unmet need for medical care there is among homeless women, what homeless women perceive to be barriers to health care, and how barriers and other factors are associated with unment needs. DESIGN: Cross-sectional study of homeless women, utilizing structured interviews. SETTING AND PARTICIPANTS: Community-based probability sample of 974 homeless women aged 15 to 44 years. MAIN OUTCOME MEASURES: Perceived unmet need for medical care in the past 60 days. Relationship between unmet need and demographic variables, place of stay, source of health care, insurance, and perceived barriers to care. RESULTS: Of the 974 women, 37% reported unmet need for medical care. Controlling for other factors, the odds of unmet need were lower among those with a regular source of care (odds ratio [OR] to .35, 95% confidence interval [CI], .21 to 58), while having health insurance was not significantly associated. The odds of unmet need were higher among those who experienced the barriers: not knowing where to go (OR 2.27, 95% CI, 1.40 to 3.69), long office waiting times (OR 1.89, 95% CI 1.27 to 2.83) and being too sick to seek care (OR 2.03, 95% CI, 1.14 to 3.62). CONCLUSIONS: There is significant unmet need for medical care among homeless women. Having a regular source of care was more important than health insurance in lowering the odds of unmet need. Homeless women must be educated regarding sources of care, and clinics serving the homeless must decrease waiting times.

Applying the Gelberg-Andersen behavioral model for vulnerable populations to health services utilization in homeless women.

We applied the Gelberg-Andersen Behavioral Model for Vulnerable Populations to predict health services utilization (HSU) in 875 homeless US women. Structural models assessed the impact of predisposing (demographics, psychological distress, alcohol/drug problems, homelessness severity), enabling (health insurance, source of care, barriers) and need (illness) variables on HSU (preventive care, outpatient visits, hospitalizations). Homelessness severity predicted illness, barriers and less insurance. Distress predicted more barriers, illness and less outpatient HSU. Drug problems predicted hospitalizations. Barriers predicted more illness and less outpatient HSU. Health and homelessness indicators were worse for White women. Better housing, access to care and insurance would encourage appropriate HSU.

Risk factors for hepatitis C virus infection among homeless adults

OBJECTIVE: To describe the prevalence of hepatitis C virus (HCV) infection in a sample of homeless and impoverished adults and examine risk factors for HCV infection in the overall sample and as a function of injection drug use.DESIGN: Assays were conducted on stored sera. Socio-demographic characteristics and risky sexual activity were measured by content-specific items. Substance use was measured by a structured questionnaire. HCV antibodies were tested by enzyme-linked immunosorbent assay; a confirmatory level was defined by recombinant immunoblot assay.SETTINGS: Shelters (N=36) and outdoor locations in Los Angeles.PARTICIPANTS: Eight hundred eighty-four homeless women and/or partners or friends.RESULTS: Among this sample of 884 homeless and impoverished adults, 22% were found to be HCV infected. Lifetime injection drug users (IDUs) (cocaine, crack, and methamphetamine) and recent daily users of crack were more likely than nonusers or less-frequent users of these drugs to be HCV-infected. Similar results were found for those who had been hospitalized for a mental health problem. Among non-injection drug users and persons in the total sample, those who reported lifetime alcohol abuse were more likely than those who did not to be HCV infected. Controlling for socio-demographic characteristics, multiple logistic regression analyses revealed IDUs have over 25 times greater odds of having HCV infection than non-IDUs. HCV infection was also predicted by older age, having started living on one’s own before the age of 18, and recent chronic alcohol use. Males and recent crack users had about one and a half times greater odds of HCV infection when compared to females and non-chronic crack users.CONCLUSIONS: Targeted outreach for homeless women and their partners, including HCV testing coupled with referrals to HCV and substance abuse treatments, may be helpful.

Impoverished diabetic patients whose doctors facilitate their participation in medical decision making are more satisfied with their care.

OBJECTIVE: Greater participation in medical decision making is generally advocated for patients, and often advocated for those with diabetes. Although some studies suggest that diabetic patients prefer to participate less in decision making than do healthy patients, the empirical relationship between such participation and diabetic patients’ satisfaction with their care is currently unknown. We sought to characterize the relationship between aspects of diabetic patients’ participation in medical decision making and their satisfaction with care.DESIGN: Cross-sectional observational study.SETTING: A general medical county hospital-affiliated clinic.PARTICIPANTS: One hundred ninety-eight patients with type 2 diabetes.MAIN MEASURES: Interviews conducted prior to the doctor visit assessed patients’ desire to participate in medical decision making, baseline satisfaction (using a standardized measure), and sociodemographic and clinical characteristics. Postvisit interviews of those patients assessed their visit satisfaction and perception of their doctor’s facilitation of patient involvement in care. A discrepancy score was computed for each subject to reflect the difference between the previsit stated desire regarding participation and the postvisit report of their experience of participation.RESULTS: Overall, patients reported low postvisit satisfaction relative to national standards (mean of 70 on a 98-point scale). Patients perceived a high level of facilitation of participation (mean 88 on a 100-point scale). Facilitation of participation and the discrepancy score both independently predicted greater visit satisfaction. In particular, a 13-point (1 SD) increase in the perceived facilitation score resulted in a 12-point (0.87 SD) increase in patient satisfaction, and a 1.22 point increase (1 SD) in the discrepancy score (the extent to which the patient was allowed more participation than, at previsit, he or she desired) resulted in a 6-point (0.5 SD) increase in the satisfaction score, even after controlling for initial desire to participate. For women, but not for men, physician facilitation of participation was a positive predictor of satisfaction; for men, but not women, desire to participate was a significant positive predictor of visit satisfaction.CONCLUSION: Clinicians may feel reassured that encouraging even initially reluctant patients with diabetes to participate in medical decision making may be associated with increased patient satisfaction. Greater patient participation has the potential to improve diabetic self-care because of the likely positive effect of patient satisfaction on adherence to treatment. Further research to assess the prospective effects of enhancing physician facilitation of patient participation is likely to yield important information for the effective treatment of chronically ill patients.

Delays and Unmet Need for Health Care Among Adult Primary Care Patients in a Restructured Urban Public Health System

OBJECTIVES We estimated the prevalence and determinants of delayed and unmet needs for medical care among patients in a restructured public health system. METHODS We conducted a stratified cross-sectional probability sample of primary care patients in the Los Angeles County Department of Health Services. Face-to-face interviews were conducted with 1819 adult patients in 6 languages. The response rate was 80%. The study sample was racially/ethnically diverse. RESULTS Thirty-three percent reported delaying needed medical care during the preceding 12 months; 25% reported an unmet need for care because of competing priorities; and 46% had either delayed or gone without care. CONCLUSIONS Barriers to needed health care continue to exist among patients receiving care through a large safety net system. Competing priorities for basic necessities and lack of insurance contribute importantly to unmet health care needs.

Is Food Insufficiency Associated with Health Status and Health Care Utilization Among Adults with Diabetes

AbstractOBJECTIVES: Preliminary studies have shown that among adults with diabetes, food insufficiency has adverse health consequences, including hypoglycemic episodes and increased need for health care services. The purpose of this study was to determine the prevalence of food insufficiency and to describe the association of food insufficiency with health status and health care utilization in a national sample of adults with diabetes. METHODS: We analyzed data from adults with diabetes (n=1,503) interviewed in the Third National Health and Nutrition Examination Survey. Bivariate and multivariate analyses were used to examine the relationship of food insufficiency to self-reported health status and health care utilization. RESULTS: Six percent of adults with diabetes reported food insufficiency, representing more than 568,600 persons nationally (95% confidence interval, 368,400 to 768,800). Food insufficiency was more common among those with incomes below the federal poverty level (17% vs 4%, P≤.001). Adults with diabetes who were food insufficient were more likely to report fair or poor health status than those who were not (63% vs 43%; odds ratio, 2.2; P=.05). In a multivariate analysis, fair or poor health status was independently associated with poverty, nonwhite race, low educational achievement, and number of chronic diseases, but not with food insufficiency. Diabetic adults who were food insufficient reported more physician encounters, either in clinic or by phone, than those who were food secure (12 vs 7, P<.05). In a multivariate linear regression, food insufficiency remained independently associated with increased physician utilization among adults with diabetes. There was no association between food insufficiency and hospitalization in bivariate analysis. CONCLUSIONS: Food insufficiency is relatively common among low-income adults with diabetes and was associated with higher physician utilization.

Sheltered Versus Nonsheltered Homeless Women: Differences in Health, Behavior, Victimization, and Utilization of Care

OBJECTIVE: To contrast sociodemographic characteristics, physical and mental health status, substance use, sexual behaviors, victimization, and utilization of health services between homeless women residing in sheltered and nonsheltered environments.DESIGN: Cross-sectional survey. A structured scale was used to measure mental health status. Physical health status, substance use, sexual behavior, history of adult victimization, and health services utilization were measured by content-specific items.SETTING: Shelters (N=47) and outdoor locations in Los Angeles.PARTICIPANTS: One thousand fifty-one homeless women.RESULTS: Homeless women living on the streets were more likely than sheltered women to be white and longer-term homeless. Controlling for sociodemographic characteristics, multiple logistic regression analyses revealed that unsheltered women had over 3 times greater odds of fair or poor physical health, and over 12 times greater odds of poor mental health than sheltered homeless women. They were also more likely than sheltered women to report using alcohol or noninjection drugs, to have multiple sexual partners, and to have a history of physical assault. About half of the overall sample reported utilization of a variety of health services; however, unsheltered homeless women were less likely to utilize all of the health services that were assessed, including drug treatment.CONCLUSIONS: There is a critical need for aggressive outreach programs that provide mental health services and substance abuse treatment for homeless women on the streets. Comprehensive services that also include medical care, family planning, violence prevention, and behavioral risk reduction may be particularly valuable for homeless women, especially those living in unsheltered environments.
