Surgical Outcomes & Quality Improvement Center (SOQIC)

Directed by Karl Bilimoria, MD, MS, the Northwestern Surgical Outcomes and Quality Improvement Center is a collaborative health services, outcomes, patient safety and quality improvement research enterprise.

Areas of Research Focus

  • Developing better ways to provide hospitals with comparative data to spur internal hospital quality improvement efforts.
  • Providing patients with better comparative data through public reporting so as to assist them in selecting the best hospital for their surgical care.
  • Performing policy evaluations to examine the effect of various structural, accreditation, and legislative efforts, such as public reporting and value-based purchasing, on quality of surgical care.

Practical Initiatives

The Northwestern Surgical Outcomes and Quality Improvement Center is a collaborative health services, outcomes, patient safety, and quality improvement research enterprise between the Department of Surgery, the Northwestern Center for Healthcare Studies, the Department of Medical Social Sciences, Northwestern Memorial Hospital (NMH), the Northwestern Institute for Comparative Effectiveness Research in Oncology (NICER Onc), and others. Our research focuses on examining the quality of care delivered across the United States and subsequently developing strategies to improve healthcare quality.  Our research spans all the surgical specialties, but we have a particular focus on general surgery and surgical oncology.  Moreover, we work with NMH on numerous practical quality improvement initiatives, including American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) operations.


SOQIC, along with its collaborators, has published over 600 articles in high-impact peer-reviewed journals over the past five years, and the faculty regularly present at national meetings.  Faculty members serve in leadership positions for a number of high-profile national organizations.


SOQIC offers surgical residents a 2-year full-time postdoctoral fellowship in health services, outcomes and quality improvement research to prepare them for a career in academic surgery. Fellows earn a Master’s and receive close mentorship from surgical faculty, collaborators, and SOQIC staff. We typically mentor 6 research fellows who join us from various departments across the country. SOQIC also offers an annual Outcomes Research Course for clinicians looking to expand their knowledge of research design and methodology, receive feedback on their projects, and identify collaborators.
