Physician Case Volume is Positively Correlated with Better Patient Quality Outcomes

Research has shown that case volume is positively correlated with better patient outcomes. Here are three example studies:

• Physician volume is associated with lower mortality for HF. Patients cared for by the high-volume physicians had lower mortality than those by the low-volume physicians. Physician Volume, Specialty, and Outcomes of Care for Patients With Heart Failure - 2013
• The primary factor driving the mortality reduction associated with case volume after open AAA repair is surgeon volume Surgeon case volume, not institution case volume, is the primary determinant of in-hospital mortality after elective open abdominal aortic aneurysm repair - Mar 2011.
• Thirty-two reviews reporting on 15 surgical procedures/conditions were included. Most reviews tend to support the presence of a surgeon volume-outcome relationship. Relationship between surgeon volume and outcomes: a systematic review of systematic reviews - 2016.
• Surgeon case volume had positive impacts on procedural, financial, and clinical outcomes and this finding may be used to improve hospital's quality of care. Impact of colorectal surgeon case volume on outcomes and applications to quality improvement. - 2018
