Current Activities

State Opiod Response (SOR) Data Project

Sponsor: Arizona Health Care Cost Containment System (AHCCCS) (2019-ongoing)

Prime Sponsor: Substance Abuse & Mental Health Services Administration

This study is part Arizona’s state-wide effort to combat the opioid epidemic. CHiR is collaborating with faculty in the School of Computing, Informatics and Decision Systems Engineering and Biomedical Informatics faculty in the College of Health Solutions. The study goal is to 1) create an operational model for use by AHCCCS and other state agencies to quantify the impact of the decision-making alternatives pertinent to Opioid Use Disorder and 2) create a mobile application for use by individuals requiring immediate aid and for first responders for monitoring and targeting services.

Reporting on Arizona Medicaid Patients for Community Health Centers

Sponsor: Arizona Alliance for Community Health Centers (2014 – ongoing)

The sponsor is determining the value of Federally Qualified Health Centers (FQHCs) care of patients enrolled in AHCCCS by studying their health care utilization, cost, and quality of care. CHiR is preparing the analysis data sets, conducting the analyses, and reporting aggregate results to the sponsor. CHiR also provides weekly on-site technical services to the sponsor, creating databases of health information and analyzing local data.

Physicians’ Use, Exchange, and Evaluation of Electronic Medical Records

Sponsor: Arizona Health Care Cost Containment System (AHCCCS)/ Centers for Medicare & Medicaid Services (CMS) (2007- ongoing)

This study is an ongoing collaboration with AHCCCS to track the use of electronic medical records among allopathic and osteopathic physicians in Arizona, with a special focus on physicians who serve AHCCCS members. CHiR coordinates with the state physician licensing boards to continue implementation of the electronic survey in conjunction with applications for licensure.  CHiR collects the administrative data (licensing and survey) from the boards, merges it with other available data for analysis, and reports the findings annually.

Assessment of Medicaid Children’s Vision Health in Arizona

Sponsor: Virginia G. Piper Charitable Trust (2015 – ongoing)


The sponsor is implementing a statewide vision health initiative. To inform the initiative, CHiR has provided summary results of the vision and eye care services provided to children on Medicaid over several years. CHiR is also providing biannual reports of the use of specific vision screenings and other analyses as requested.

Financing and Service Delivery Integration for Individuals on Medicaid with Behavioral Health Disorders

Study Leader: ASU School for the Science of Health Care Delivery


This Robert Wood Johnson Foundation funded study is to improve the health care delivery and financing systems for medical care and other services provided to individuals with behavioral health disorders. CHiR prepares analysis data sets and summary results (integrated and non-integrated) of varied data, including state Medicaid data, state hospital discharge data, Maricopa County Sheriff’s Office booking and release data, and county adult probation data.

Value of Care Among Allopathic and Osteopathic Physicians

Sponsor: Midwestern University (American Osteopathic Association)

This collaborative study will measure the value of osteopathic care by comparing patient outcomes and costs of care for specific diseases/conditions treated by osteopathic physicians versus allopathic physicians. CHiR will group Medicaid claims into episodes of care for diseases/conditions of interests and treated by osteopathic physicians. A comparison group of patients treated by allopathic physicians will be propensity matched. Arizona Physician Workforce Data will be linked to the claims and analysis data sets will be created and analyzed for the research team.


CHiR also regularly fulfills various smaller requests for health information for use in proposals, internal operations, programs/interventions, publications, and other studies.
