Population Health and Health Services

Mission

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.

Dr. Caroline Freiermuth is an Associate Professor of Emergency Medicine. Her research has focused on managing pain while minimizing risks, including the risk of opioid use disorder. Dr. Freiermuth's expertise in treatment for opioid use disorder and harm reduction has been recognized through her roles on multiple active grants. She serves as a Co-investigator on the NIDA HEALing communities study, acting as a facilitator for implementing new programs for prevention and treatment of opioid use disorder in emergency departments across the state of Ohio. As the principal investigator of the Emergency Department Comprehensive Care grant, awarded by the Ohio Department of Health, Dr. Freiermuth leads the coordination of expanded services for persons with opioid use disorder across local health systems, ensuring that emergency departments are adequately identifying those at risk for the disease and have the needed resources and protocols to treat these patients. Dr. Freiermuth recently enrolled over 1300 hundred patients from three emergency departments into a pharmacogenomics study, funded by the Ohio Attorney General's office. Through this study, she seeks to identify genetic markers associated with opioid use disorder, with the long term goal of running trials to determine if identifying this risk before opioid exposure can decrease the risk of developing opioid use disorder.

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.

head shotDr. Manchak’s work examines the effectiveness of programs and policies for individuals in the criminal justice system who have mental illness and/or substance use disorder. Since 2012, she has been an external evaluator (PI) on several different projects that focus on justice-involved individuals with opioid addiction, specifically. This includes 4 evaluations of SAMHSA-funded programs affiliated with the local drug court, 2 evaluations of the Hamilton County Quick Response Team, and 1 evaluation of the Hamilton County Law Enforcement Assisted Diversion (LEAD) program. In her own investigator-led research that focuses more specifically on serious mental illness (schizophrenia, bipolar disorder, major depression), she examines the influence of substance use on clinical and criminal outcomes. She has also conducted a study of practitioners in Hamilton County (EMS, treatment, law enforcement/corrections) to examine the personal and professional impact of the opioid crisis.

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.
