Population Health and Health Services


Much emphasis in the field of addiction medicine is placed on the absolutely essential goal of developing and testing treatments for substance use disorder (SUD). Yet, a comprehensive response requires a much broader view. Addiction arises from and is exacerbated by a host of factors involving systems and populations and leads to a wide variety of adverse consequences. For example:

  • It may even be that addiction can spread like a contagion through social networks
  • Stigma is a profound problem (and intervention target) that involves even those who will never suffer directly from addiction. 
  • Effective prevention of addiction would obviate the need for treatment entirely. 
  • Those with addiction cannot be treated if they are not accessing treatment services. 
  • Intervention services need to be operationalized and comparatively evaluated.  How to effectively and efficiently implement services is an enormous knowledge gap in many conditions and is even more complicated in addiction where patient motivation for treatment is uniquely problematic.  Moreover, individuals with co-occurring mental health issues tend to be high healthcare utilizers but optimal treatment approaches for this population has received relatively little research attention.
  • Policy level intervention can have profound effects (positive or negative) on the prevalence and consequences of addiction. 
  • Addiction is well-known to cause or worsen a host of co-morbidities (e.g., infectious disease) that in turn require their own prevention, treatment, and policy solutions. 
  • A full understanding of longitudinal outcomes in health and economic terms can assist with policy development, intervention prioritization, and motivating system change.

The mission of the “Population Health and Health Services (PHHS) Core” of the UC Center for Addiction Research is to conduct the science necessary to place addiction in context, prevent the condition when possible, and limit the consequences of addiction when it does occur.  Core investigators multidisciplinary and highly synergistic interests range from surveillance and epidemiology, primary and secondary prevention intervention, operations and implementation, and outcomes assessment. These categories apply both to addiction itself and related co-morbidities.

Throughout his academic career, Dr. Lyons has worked to reduce fragmentation in systems and mission that separates public health and other healthcare entities.  The emergency department setting is a compelling platform for launching this focus given its role as a safety net provider, remarkably high prevalence of substance use, mental health, and infectious disorders, and its frequent interaction with virtually all aspects of the healthcare, public health, and social service systems.

Dr. Lyons has led the University of Cincinnati’s Early Intervention Program (EIP) and Department of Emergency Medicine Division of Public Health and Health Services Research since 2002.  The EIP is an ever-expanding collection of clinical prevention initiatives that has been continuously funded for over two decades by a variety of public health, community, healthcare, and industry sponsors.  The program augments and directly modifies existing emergency care and other healthcare services, as well as providing services in community settings in partnership with public health agencies and community-based organizations.  Approximately 100 nurses, physicians, researchers, and other allied health professionals began their initial career development as EIP service providers.  This body of clinical and administrative work directly informs Dr. Lyons’ research which has been variously funded by NIH, CDC, AHRQ, EMF, and SAMHSA.  Most recently he is serving as co-lead of the “Intervention Core” for the Ohio portion of the massive NIH/SAMHSA HEALing Communities Study, which will engage 19 counties throughout Ohio in comprehensive and rapid reduction of untreated opioid use disorder and related overdose mortality.

Healing Communities Study

The HEALing Communities Study will determine how to address the opioid epidemic through prevention, treatment and recovery. To assess the effectiveness of different interventions, the study will compare results between communities, and in order to make these comparisons, participating communities were randomly assigned using a scientific algorithm to start these interventions either in December 2019 (Wave 1) or December 2021 (Wave 2).

  • The 9 counties in the first wave are Ashtabula, Athens, Cuyahoga, Darke, Guernsey, Greene, Hamilton, Lucas, Scioto.
  • The 9 counties in the second wave are Allen, Brown, Franklin, Huron, Jefferson, Ross, Stark, Williams and Wyandot.

Throughout the project, all participating communities will continue to get all the other treatment and prevention resources and services that they would otherwise receive.

John Winhusen, UC professor of psychiatry and behavioral neuroscience, director of the Addiction Sciences Division and principal investigator of the Ohio Valley Node in the NIDA Clinical Trials Network, is serving as a co-principal investigator for the state of Ohio with Dr. Rebecca Jackson, director of the Ohio State University’s Center for Clinical and Translational Science, along with Alisha Nelson of RecoveryOhio, an initiative created by Gov. Mike DeWine. UC, Ohio State and Case Western are coordinating the research study in collaboration with the 19 counties. UC faculty members Jennifer Brown, associate professor of psychiatry in the addiction sciences division, and Dr. Michael Lyons, associate professor of emergency medicine, are leading the statewide effort of intervention implementation across the selected counties.

The HEALing Communities Study is funded and supported by the National Institute on Drug Abuse, part of the National Institutes of Health, in partnership with the Substance Abuse and Mental Health Services Administration.

wexelblatt-scottDr. Wexelblatt is a pediatrician and researcher focused on improving perinatal health outcomes in regional populations.  He is  currently the Regional Director of Newborn Services for Cincinnati Children's Hospital Medical Center (CCHMC) Perinatal Institute, which serves eight level 2 hospitals and three level 1 nurseries in our region.  As the regional faculty representative for the Ohio Children’s Hospital Association (OCHA) subcommittee on Neonatal Abstinence Syndrome (NAS), he helped establish a protocol for NAS for twenty Ohio children’s and maternity hospitals.  He led in the reporting of key findings from OCHA demonstrating that improved outcomes for NAS following an infant’s in-utero exposure to opioids could be achieved through the utilization of standard treatment protocols with stringent weaning guidelines. Subsequently, he co-led the analysis and writing of a follow-up study reporting improvement in NAS outcomes after adoption of the collaborative guidelines. Building upon his work with the OCHA collaborative, he served as a primary or co-investigator in several additional regional analyses designed to provide evidence for further optimizing NAS guidelines. Analyses of outcomes following methadone versus buprenorphine weaning and a comparative effectiveness evaluation of conventional methadone weaning versus weaning with a pharmacokinetic modeled methadone protocol were published.  He is currently participating as a faculty member of the Ohio Perinatal Quality Collaboration (OPQC) disseminating our findings to 53 delivery hospitals in Ohio to improve the care of the opioid exposed infant.  Through their statewide collaborations of OCHA and OPQC, they have created a standardized protocol to safely decrease the length of stay.  They have also showed that a pharmacokinetic modeled taper reduced length of stay by three days, and that buprenorphine may be a safe and more effective option for pharmacologic treatment in the setting of NAS.
