Study on Cancer Surgery Volume, Outcomes at California Hospitals to Be Released Thursday
July 6 webinar to detail study processes, data gathered and implications for hospitals

Over the past three years, the California HealthCare Foundation (CHCF) has partnered with the California Office of Statewide Health Planning and Development, a health services researcher at Stanford and the Cancer Prevention Institute of California to conduct a study measuring the volume of certain types of cancer surgeries performed at each hospital for which there is scientific evidence of an association between low volume and increased mortality/poor outcomes. The study examines 11 types of cancer, which were chosen based on an extensive literature review by the Cancer Prevention Institute of California: bladder, brain, breast, colon, esophagus, liver, lung, pancreas, prostate, rectum and stomach. Low volume is defined as between one and five surgeries for any of the 11 types of cancer. After the study’s initial data release in 2015, Hospital Quality Institute (HQI) and CHA contacted leadership in hospitals with low volume to discuss their results and the study findings. 

On Thursday, June 28, the group will release an updated study of unblinded data to the media, in addition to a three-page CHCF brief that includes recommendations for hospitals. This year’s study results are based on 2014-15 data to determine changes, if any, in hospital cancer surgery volume. The study found essentially no change in the distribution of low-volume cancer surgeries in California hospitals.

Earlier this month, CHA Chief Medical Officer Dr. David Perrott and HQI President/CEO Julie Morath notified CEOs of organizations identified in the study about their data via email. 

CHA Webinar to Explain Study Background and Suggest Courses of Action

CHA will host a webinar July 6 from 10 a.m. – noon (PT) to provide hospital leadership teams with a thorough analysis of the study and offer recommendations for action. For more information or to register, visit
