The Health Services and Outcomes Research Institute

The Institute’s Goal

To advance scientific knowledge through multi-disciplinary collaborations aimed at better understanding factors that affect:

  • Patient access to healthcare services
  • Epidemiology of diseases
  • Acute and chronic care
  • Health behaviors
  • Health outcomes

HSOR efforts are diverse and broad, with studies ranging from the individual patient experience to large population outcomes. Studies span all care settings, from the patient’s home and pre-hospital setting to primary care and specialty clinics, urgent care centers, emergency department, intensive care, and inpatient units.  It also encompasses ongoing and long-term care.

The Institute’s Mission

To support, promote, and expand excellence in clinical and translational science research related to health services, and to create and sustain strategies that enable investigators to collaborate, excel, and transform healthcare through high-quality research. This includes the following:

  • Inform health care policy development
  • Aim to reduce health disparities
  • Inspire innovation in evidence-based science

The HSOR institute further seeks to enhance the impact of HSOR by engaging with community partners in all stages of research (conceptual design to dissemination).  Current grant-supported activities are in the focus areas of:

  • Health disparities
  • Antibiotic stewardship
  • Community engagement
  • Technology innovations in patient engagement
  • Chronic disease management
