Health Care Utilization Patterns of Homeless Individuals in Boston: Preparing for Medicaid Expansion Under the Affordable Care Act

OBJECTIVES We studied 6494 Boston Health Care for the Homeless Program (BHCHP) patients to understand the disease burden and health care utilization patterns for a group of insured homeless individuals. METHODS We studied merged BHCHP data and MassHealth eligibility, claims, and encounter data from 2010. MassHealth claims and encounter data provided a comprehensive history of health care utilization and expenditures, as well as associated diagnoses, in both general medical and behavioral health services sectors and across a broad range of health care settings. RESULTS The burden of disease was high, with the majority of patients experiencing mental illness, substance use disorders, and a number of medical diseases. Hospitalization and emergency room use were frequent and total expenditures were 3.8 times the rate of an average Medicaid recipient. CONCLUSIONS The Affordable Care Act provides a framework for reforming the health care system to improve the coordination of care and outcomes for vulnerable populations. However, improved health care coverage alone may not be enough. Health care must be integrated with other resources to address the complex challenges presented by inadequate housing, hunger, and unsafe environments.

Food insufficiency and health services utilization in a national sample of homeless adults.

BACKGROUNDHomeless people have high rates of hospitalization and emergency department (ED) use. Obtaining adequate food is a common concern among homeless people and may influence health care utilization.OBJECTIVEWe tested the hypothesis that food insufficiency is related to higher rates of hospitalization and ED use in a national sample of homeless adults.DESIGNWe analyzed data from the 2003 Health Care for the Homeless (HCH) User Survey.PARTICIPANTSParticipants were 966 adults surveyed at 79 HCH clinic sites throughout the US. The study sample was representative of over 436,000 HCH clinic users nationally.MEASURESWe determined the prevalence and characteristics of food insufficiency among respondents. Using multivariable logistic regression, we examined the association between food insufficiency and four past-year acute health services utilization outcomes: (1) hospitalization for any reason, (2) psychiatric hospitalization, (3) any ED use, and (4) high ED use (≥4 visits).RESULTSOverall, 25% of respondents reported food insufficiency. Among them, 68% went a whole day without eating in the past month. Chronically homeless (p = 0.01) and traumatically victimized (p = 0.001) respondents were more likely to be food insufficient. In multivariable analyses, food insufficiency was associated with significantly greater odds of hospitalization for any reason (AOR 1.59, 95% CI 1.07, 2.36), psychiatric hospitalization (AOR 3.12, 95% CI 1.73, 5.62), and high ED utilization (AOR 2.83, 95% CI 1.32, 6.08).CONCLUSIONSOne-fourth of homeless adults in this national survey were food insufficient, and this was associated with increased odds of acute health services utilization. Addressing the adverse health services utilization patterns of homeless adults will require attention to the social circumstances that may contribute to this issue.

Developing Core Competencies for the Prevention and Management of Prescription Drug Misuse: A Medical Education Collaboration in Massachusetts

Drug overdose has become the leading cause of injury death in the United States. More than half of those deaths involve prescription drugs, specifically opioids. A key component of addressing this national epidemic is improving prescriber practices. A review of the curricula at the four medical schools in Massachusetts revealed that, although they taught components of addiction medicine, no uniform standard existed to ensure that all students were taught prevention and management strategies for prescription drug misuse. To fill this gap, the governor and the secretary of health and human services invited the deans of the state’s four medical schools to convene to develop a common educational strategy for teaching safe and effective opioid-prescribing practices. With leadership from the Department of Public Health and Massachusetts Medical Society, the deans formed the Medical Education Working Group in 2015. This group reviewed the relevant literature and current standards for treating substance use disorders and defined 10 core competencies for the prevention and management of prescription drug misuse. The medical schools have incorporated these competencies into their curricula and have committed to assessing students’ competence in these areas. The members of the Medical Education Working Group have agreed to continue to work together on key next steps, including connecting these competencies to those for residents, equipping interprofessional teams to address prescription drug misuse, and developing materials in pain management and opioid misuse for practicing physicians. This first-in-the-nation partnership has yielded cross-institutional competencies that aim to address a public health emergency in real time.

Disparities in Cancer Screening: Acceptance of Pap Smears among Homeless Women

AIMS Cervical cancer is a preventable disease through screening and early treatment. Rates of cervical cancer are higher in impoverished women, including homeless women. This study assessed the acceptance of free and accessible Pap smears offered to homeless women in a respite care setting. METHODS A convenience sample of 205 adult women receiving respite care at a facility for homeless people in Boston, Massachusetts, between 2004 and 2007 were offered screening for cervical cancer during routine encounters with the medical staff during their stay. Rates of acceptance of screening as well as medical and sociodemographic information were collected on the women. RESULTS Of 205 women enrolled in the study, 129 (63%) were in need of screening and offered a Pap smear; 80 (62%) accepted and 49 (38%) declined. Of those who agreed to be tested, 56 (70%) had a Pap smear performed, resulting in 10 (18%) atypical results (atypical squamous cells of undetermined significance [ASCUS] or low-grade squamous intraepithelial lesion [LGSIL]) and 15 (27%) benign findings needing follow-up (e.g., vaginitis without evidence of malignancy). CONCLUSIONS A large proportion of homeless women receiving respite care decline a free Pap smear despite being in medical need of cervical cancer screening. Access and cost may not be the only barriers to screening among homeless women, and new and innovative approaches to screening in vulnerable populations need to be investigated in order to close the disparity gap.

Frequent Emergency Department Visits and Hospitalizations Among Homeless People With Medicaid: Implications for Medicaid Expansion

OBJECTIVES We examined factors associated with frequent hospitalizations and emergency department (ED) visits among Medicaid members who were homeless. METHODS We included 6494 Massachusetts Medicaid members who received services from a health care for the homeless program in 2010. We used negative binomial regression to examine variables associated with frequent utilization. RESULTS Approximately one third of the study population had at least 1 hospitalization and two thirds had 1 or more ED visits. More than 70% of hospitalizations and ED visits were incurred by only 12% and 21% of these members, respectively. Homeless individuals with co-occurring mental illness and substance use disorders were at greatest risk for frequent hospitalizations and ED visits (e.g., incidence rate ratios [IRRs] = 2.9-13.8 for hospitalizations). Individuals living on the streets also had significantly higher utilization (IRR = 1.5). CONCLUSIONS Despite having insurance coverage, homeless Medicaid members experienced frequent hospitalizations and ED visits. States could consider provisions under the Patient Protection and Affordable Care Act (e.g., Medicaid expansion and Health Homes) jointly with housing programs to meet the needs of homeless individuals, which may improve the quality and cost effectiveness of care.

Factors Associated with Geriatric Syndromes in Older Homeless Adults

Although older homeless adults have high rates of geriatric syndromes, risk factors for these syndromes are not known. We used multivariable regression models to estimate the association of subject characteristics with the total number of geriatric syndromes in 250 homeless adults aged 50 years and older. Geriatric syndromes included falls, cognitive impairment, frailty, major depression, sensory impairment, and urinary incontinence. A higher total number of geriatric syndromes was associated with having less than a high school education, medical comorbidities (diabetes and arthritis), alcohol and drug use problems, and difficulty performing one or more activities of daily living. Clinicians who care for older homeless patients with these characteristics should consider screening them for geriatric syndromes. Moreover, this study identifies potentially modifiable risk factors associated with the total number of geriatric syndromes in older homeless adults. This knowledge may provide targets for clinical interventions to improve the health of older homeless patients.

Disparities in Cancer Incidence, Stage, and Mortality at Boston Health Care for the Homeless Program.

INTRODUCTION Homeless people have a high burden of cancer risk factors and suboptimal rates of cancer screening, but the epidemiology of cancer has not been well described in this population. We assessed cancer incidence, stage, and mortality in homeless adults relative to general population standards. METHODS We cross-linked a cohort of 28,033 adults seen at Boston Health Care for the Homeless Program in 2003-2008 to Massachusetts cancer registry and vital registry records. We calculated age-standardized cancer incidence and mortality ratios (SIRs and SMRs). We examined tobacco use among incident cases and estimated smoking-attributable fractions. Trend tests were used to compare cancer stage distributions with those in Massachusetts adults. Analyses were conducted in 2012-2015. RESULTS During 90,450 person-years of observation, there were 361 incident cancers (SIR=1.13, 95% CI=1.02, 1.25) and 168 cancer deaths (SMR=1.88, 95% CI=1.61, 2.19) among men, and 98 incident cancers (SIR=0.93, 95% CI=0.76, 1.14) and 38 cancer deaths (SMR=1.61, 95% CI=1.14, 2.20) among women. For both sexes, bronchus and lung cancer was the leading type of incident cancer and cancer death, exceeding Massachusetts estimates more than twofold. Oropharyngeal and liver cancer cases and deaths occurred in excess among men, whereas cervical cancer cases and deaths occurred in excess among women. About one third of incident cancers were smoking-attributable. Colorectal, female breast, and oropharyngeal cancers were diagnosed at more-advanced stages than in Massachusetts adults. CONCLUSIONS Efforts to reduce cancer disparities in homeless people should include addressing tobacco use and enhancing participation in evidence-based screening.

Health Outcomes of Obtaining Housing Among Older Homeless Adults

OBJECTIVES We determined the impact of obtaining housing on geriatric conditions and acute care utilization among older homeless adults. METHODS We conducted a 12-month prospective cohort study of 250 older homeless adults recruited from shelters in Boston, Massachusetts, between January and June 2010. We determined housing status at follow-up, determined number of emergency department visits and hospitalizations over 12 months, and examined 4 measures of geriatric conditions at baseline and 12 months. Using multivariable regression models, we evaluated the association between obtaining housing and our outcomes of interest. RESULTS At 12-month follow-up, 41% of participants had obtained housing. Compared with participants who remained homeless, those with housing had fewer depressive symptoms. Other measures of health status did not differ by housing status. Participants who obtained housing had a lower rate of acute care use, with an adjusted annualized rate of acute care visits of 2.5 per year among participants who obtained housing and 5.3 per year among participants who remained homeless. CONCLUSIONS Older homeless adults who obtained housing experienced improved depressive symptoms and reduced acute care utilization compared with those who remained homeless.

A Randomized Control Trial of a Chronic Care Intervention for Homeless Women with Alcohol Use Problems

A clinician-randomized trial was conducted using the chronic care model for disease management for alcohol use problems among n = 82 women served in a health care for the homeless clinic. Women with problem alcohol use received either usual care or an intervention consisting of a primary care provider (PCP) brief intervention, referral to addiction services, and on-going support from a care manager (CM) for 6 months. Both groups significantly reduced their alcohol consumption, with a small effect size favoring intervention at 3 months, but there were no significant differences between groups in reductions in drinking or in housing stability, or mental or physical health. However, intervention women had significantly more frequent participation in substance use treatment services. Baseline differences and small sample size limit generalizability, although substantial reductions in drinking for both groups suggest that screening and PCP brief treatment are promising interventions for homeless women with alcohol use problems.

Use of Acute Care Services Among Older Homeless Adults

the study cohort was highly educated, numerate, and well insured, with a higher than average income level, thus differing from a population-based cohort of patients with DCIS. Second, we administered hypothetical scenarios to individuals personally not diagnosed as having DCIS. While it is possible that patients with DCIS may react differently to the survey, the use of hypothetical scenarios allowed us to explore women’s preferences toward systemic therapy and active surveillance, unbiased by previous knowledge regarding DCIS and standard modes of treatment options. Finally, the projected outcomes in the scenarios were generalized and static, whereas true outcomes vary depending on patient age, tumor grade, and other case-specific factors. We conclude that the terminology used to describe DCIS has a significant and important impact on patients’ perceptions of treatment alternatives. Health care providers who use “cancer” to describe DCIS must be particularly assiduous in ensuring that patients understand the important distinctions between DCIS and invasive cancer.
