The Dana and Andrew Stone Chair in Social Policy
• Dr. Culhane’s primary area of research is homelessness and assisted housing policy. His most recent research has focused on the premature aging of the adult homeless population on service systems use and costs. • Dr. Culhane co-directs the Actionable Intelligence for Social Policy initiative, a MacArthur-initiated network to promote the development of integrated database systems (IDS) by states and localities for policy analysis and systems reform. Funding from the Annie E. Casey foundation is supporting a training and technical assistance effort for states and local governments working toward implementation of an IDS.

    Prevalence of Treated Behavioral Disorders among Adult Shelter Users: A Longitudinal Study
    (1998) Culhane, Dennis P; Averyt, June M; Hadley, Trevor R
    Of 27,638 homeless adults admitted to Philadelphia public shelters in the years 1990 through 1992, 20.1% received treatment for a mental health disorder, and 25.3% for a substance use disorder in the years 1985 through 1993. An additional 20.7% were identified as having untreated substance use problems. Overall, a total of 65.5% of adult shelter users were identified as ever having had a mental health or substance use problem, treated or untreated.

    The 2007 Annual Homeless Assessment Report to Congress
    (2008-06-01) Khadduri, Jill; Culhane, Dennis P; Cortes, Alvaro; Buron, Larry; Poulin, Stephen
    The 2007 AHAR is the first AHAR based on an entire year of data about persons who use emergency and transitional housing programs. In addition, the report contains new information about the seasonal patterns of homelessness and long-term users of shelters and presents new appendices that provide community-level information on the number of homeless persons.

    Alcohol Consumption, Alcohol Outlets, and the Risk of Being Assaulted With a Gun
    (2009-05-01) Branas, Charles; Richmond, Therese S; Culhane, Dennis P; Wiebe, Douglas; Elliott, Michael R
    BACKGROUND: We conducted a population-based case-control study to better delineate the relationship between individual alcohol consumption, alcohol outlets in the surrounding environment, and being assaulted with a gun. METHODS: An incidence density sampled case-control study was conducted in the entire city of Philadelphia from 2003 to 2006. We enrolled 677 cases that had been shot in an assault and 684 population-based controls. The relationships between 2 independent variables of interest, alcohol consumption and alcohol outlet availability, and the outcome of being assaulted with a gun were analyzed. Conditional logistic regression was used to adjust for numerous confounding variables. RESULTS: After adjustment, heavy drinkers were 2.67 times as likely to be shot in an assault when compared with nondrinkers (p < 0.10) while light drinkers were not at significantly greater risk of being shot in an assault when compared with nondrinkers. Regression-adjusted analyses also demonstrated that being in an area of high off-premise alcohol outlet availability significantly increased the risk of being shot in an assault by 2.00 times (p < 0.05). Being in an area of high on-premise alcohol outlet availability did not significantly change this risk. Heavy drinkers in areas of high off-premise alcohol outlet availability were 9.34 times (p < 0.05) as likely to be shot in an assault. CONCLUSIONS: This study finds that the gun assault risk to individuals who are near off-premise alcohol outlets is about the same as or statistically greater than the risk they incur from heavy drinking. The combination of heavy drinking and being near off-premise outlets resulted in greater risk than either factor alone. By comparison, light drinking and being near on-premise alcohol outlets were not associated with increased risks for gun assault. Cities should consider addressing alcohol-related factors, especially off-premise outlets, as highly modifiable and politically feasible approaches to reducing gun violence.

    Connections Between AIDS and Homelessness
    (2001-06-15) Culhane, Dennis P; Gollub, Erica E
    Although the links between health and environment are well known, interventions that target these associations in order to improve health are rare. Health and social service agencies often function independently of one another, maintaining separate, unlinked databases. For example, relationships among homelessness, AIDS, and tuberculosis have been noted, but services have not focused on the intersecting populations these conditions affect. This Issue Brief summarizes efforts to merge databases and provide policymakers with information to guide housing, social service, and health care resources. The investigators identify risk factors associated with AIDS among the homeless, and homelessness among people with AIDS.

    Supportive Housing for Homeless People with Severe Mental Illness
    (2002-02-20) Culhane, Dennis P; Hadley, Trevor; Metreaux, Stephen
    Research suggests that as many as 110,000 single adults with severe mental illness (SMI) are homeless on any given day in the United States. The combination of mental illness and homelessness make this population especially hard to reach through either housing or mental health programs alone. Supportive housing programs, which provide independent housing along with health and social services, hold great promise for this population, but are costly to launch and maintain. This Issue Brief highlights a landmark study that examines the extent to which supportive housing costs are offset by reductions in the use of public services for health, corrections, and shelter.

    Novel Linkage of Individual and Geographic Data to Study Firearm Violence
    (2008-08-01) Branas, Charles; Culhane, Dennis P; Richmond, Therese S; Wiebe, Douglas
    Firearm violence is the end result of a causative web of individual-level and geographic risk factors. Few, if any, studies of firearm violence have been able to simultaneously determine the population-based relative risks that individuals experience as a result of what they were doing at a specific point in time and where they were, geographically, at a specific point in time. This paper describes the linkage of individual and geographic data that was undertaken as part of a population-based case-control study of firearm violence in Philadelphia. New methods and applications of these linked data relevant to researchers and policymakers interested in firearm violence are also discussed.

    Ending Family Homelessness in Massachusetts: A New Approach for the Emergency Assistance Program
    (2010-05-11) Culhane, Dennis P; Byrne, Thomas
    This paper explores the current opportunity for policy reform of the Emergency Assistance (EA) system in Massachusetts. Recent initiatives by the state are described that have provided a context for systems change. Some of the challenges posed by the current program are discussed, particularly the lack of cost containment, and the resulting fact that significant public resources are spent supporting long-term stays in shelters and motels, which are not good for families or children. After an exploration of funding and resource issues, the paper concludes by establishing the foundation for changing the current system into one that would be outcome oriented, driven by the objective of housing stabilization and serve families in a more timely, effective and efficient manner.

    The Annual Homeless Assessment Report to Congress
    (2007-02-01) Khadduri, Jill; Culhane, Dennis P.; Holin, Mary Joel; Buron, Larry; Cortes, Alvaro; Poulin, Stephen
    The U.S. Department of Housing and Urban Development (HUD) is pleased to present this national report on homelessness in America. The report was developed in response to Congressional directives that began in 2001 and charged the Department with assisting communities to implement local Homeless Management Information Systems or HMIS. The primary goals in promoting local HMIS implementation are to improve the delivery of services to homeless clients and to increase understanding of their characteristics and needs at the local and national levels. According to Senate Report 109-109, "The implementation of this new system would allow the Department to obtain meaningful data on the nation’s homeless population and develop annual reports through an Annual Homeless Assessment Report (AHAR).
