Although homelessness ranks as one of society's most pressing and visible health equity challenges, the academic community has not actively addressed its health impacts, root causes, and potential solutions. Few schools and programs of public health even offer a basic course for students. In the COVID-19 pandemic era, academia must demonstrate urgency to address homelessness and educate learners, motivate fledgling researchers, inform policy makers, offer community-engaged and evidence-based studies, and join in the growing national debate about best approaches.

Homelessness remains a pervasive, long-standing problem in the United States and is poised to increase as a result of the COVID-19 pandemic. Individuals experiencing homelessness bear a higher burden of complex medical and mental health illnesses and often struggle to obtain quality and timely health care. The United States desperately needs to train a workforce to confront this large and growing crisis, but few health professional schools currently devote curricula to the clinical needs of people experiencing homelessness.

Objective: The long-term outcomes of permanent supportive housing for chronically unsheltered individuals, or rough sleepers, are largely unknown. We therefore assessed housing outcomes for a group of unsheltered individuals who were housed directly from the streets after living outside for decades.

Methods: Using an open-cohort design, 73 chronically unsheltered individuals were enrolled and housed in permanent supportive housing directly from the streets of Boston from 2005 to 2019.

Opioid overdose is a leading cause of death among homeless individuals. Combining psychoactive substances with opioids increases overdose risk. This study aimed to describe intoxication patterns at a drop-in space offering medical monitoring and harm reduction services to individuals who arrive intoxicated and at risk of overdose.

People experiencing homelessness are at high risk for coronavirus disease 2019 (COVID-19). In March 2020, Boston Health Care for the Homeless Program, in partnership with city and state public health agencies, municipal leaders, and homeless service providers, developed and implemented a citywide COVID-19 care model for this vulnerable population. Components included symptom screening at shelter front doors, expedited testing at pop-up sites, isolation and management venues for symptomatic people under investigation and for people with confirmed disease, quarantine venues for asymptomatic exposed people, and contact investigation and tracing.

We assessed the ability of high-risk criteria developed by Boston Health Care for the Homeless Program to identify increased mortality during a 10-year cohort study (January 2000-December 2009) of 445 unsheltered adults. To qualify as high-risk for mortality, an individual slept unsheltered for six consecutive months or longer plus had one or more of the following characteristics: tri-morbidity, defined as co-occurring medical, psychiatric, and addiction diagnoses; one or more inpatient or respite admissions; three or more emergency department visits; 60 years old or older; HIV/AIDS; cirrhosis; renal failure; frostbite, hypothermia, or immersion foot. A total of 119 (26.

Provider organizations are increasingly held accountable for health care spending in vulnerable populations. Longitudinal data on health care spending and use among people experiencing episodes of homelessness could inform the design of alternative payment models. We used Medicaid claims data to analyze spending and use among 402 people who were continuously enrolled in the Boston Health Care for the Homeless Program (BHCHP) from 2013 through 2015, compared to spending and use among 18,638 people who were continuously enrolled in Massachusetts Medicaid with no evidence of experiencing homelessness.

Objective: Electronic medical record (EMR) implementation at centers caring for homeless people is constrained by limited resources and the increased disease burden of the patient population. Few informatics articles address this issue. This report describes Boston Health Care for the Homeless Program's migration to new EMR software without loss of unique care elements and processes.

Importance: Previous studies have shown high mortality rates among homeless people in general, but little is known about the patterns of mortality among "rough sleepers," the subgroup of unsheltered urban homeless people who avoid emergency shelters and primarily sleep outside.

Objectives: To assess the mortality rates and causes of death for a cohort of unsheltered homeless adults from Boston, Massachusetts.

Design, Setting, And Participants: A 10-year prospective cohort study (2000-2009) of 445 unsheltered homeless adults in Boston, Massachusetts, who were seen during daytime street and overnight van clinical visits performed by the Boston Health Care for the Homeless Program's Street Team during 2000.

Objectives: We quantified tobacco-, alcohol-, and drug-attributable deaths and their contribution to mortality disparities among homeless adults.

Methods: We ascertained causes of death among 28 033 adults seen at the Boston Health Care for the Homeless Program in 2003 to 2008. We calculated population-attributable fractions to estimate the proportion of deaths attributable to tobacco, alcohol, or drug use.

Objectives: We compared homeless patients' experiences of care in health care organizations that differed in their degree of primary care design service tailoring.

Methods: We surveyed homeless-experienced patients (either recently or currently homeless) at 3 Veterans Affairs (VA) mainstream primary care settings in Pennsylvania and Alabama, a homeless-tailored VA clinic in California, and a highly tailored non-VA Health Care for the Homeless Program in Massachusetts (January 2011-March 2012). We developed a survey, the "Primary Care Quality-Homeless Survey," to reflect the concerns and aspirations of homeless patients.

Background: Homeless persons experience excess mortality, but US-based studies on this topic are outdated or lack information about causes of death. To our knowledge, no studies have examined shifts in causes of death for this population over time.

Methods: We assessed all-cause and cause-specific mortality rates in a cohort of 28 033 adults 18 years or older who were seen at Boston Health Care for the Homeless Program from January 1, 2003, through December 31, 2008.

Despite stereotypes of the homeless population as underweight, the literature lacks a rigorous analysis of weight status in homeless adults. The purpose of this study is to present the body mass index (BMI) distribution in a large adult homeless population and to compare this distribution to the non-homeless population in the United States. Demographic, BMI, and socioeconomic variables from patients seen in 2007-2008 were collected from the Boston Health Care for the Homeless Program (BHCHP).

Background: Homeless 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.

Objective: We tested the hypothesis that food insufficiency is related to higher rates of hospitalization and ED use in a national sample of homeless adults.

During the past 25 years, the Boston Health Care for the Homeless Program has evolved into a service model embodying the core functions and essential services of public health. Each year the program provides integrated medical, behavioral, and oral health care, as well as preventive services, to more than 11 000 homeless people. Services are delivered in clinics located in 2 teaching hospitals, 80 shelters and soup kitchens, and an innovative 104-bed medical respite unit.

Objectives: We assessed the prevalence and predictors of past-year unmet needs for 5 types of health care services in a national sample of homeless adults.

Methods: We analyzed data from 966 adult respondents to the 2003 Health Care for the Homeless User Survey, a sample representing more than 436,000 individuals nationally. Using multivariable logistic regression, we determined the independent predictors of each type of unmet need.

Medical respite programs offer medical, nursing, and other care as well as accommodation for homeless persons discharged from acute hospital stays. They represent a community-based adaptation of urban health systems to the specific needs of homeless persons. This article examines whether post-hospital discharge to a homeless medical respite program was associated with a reduced chance of 90-day readmission compared to other disposition options.
