Bariatric Surgery Linked To Long Term Mortality Reduction Interview with:
Oma Reges, PhD
Clalit Research Institute, Clalit Health Services, Tel Aviv, Israel
Department of Health Systems Management, Ariel University, Ariel, Israel What is the background for this study? What are the main findings?

Response: Israel, based on the most recently published data (2015), performs more per-capita bariatric surgery than the U.S.A (about 9,000 to 9,500 procedures annually, which is 1.8 times higher rate per capita than the U.S.A, where there are about 200,000 procedures a year).

It is important to evaluate the impact of these procedures on health status, as there is a lack of data of the effectiveness of these procedures over time. We were able to document lower mortality rates, of up to 50%, in the obese patient undergoing surgery as opposed to matched obese patients who continue with usual care. What should readers take away from your report?

Response: The importance of the observation, that over time, weight reduction prevents mortality up to 50%, preserves weight reduction, and prevents associated morbidity emphasizes the importance of the availability of bariatric surgery as a therapeutic tool in all appropriate patients What recommendations do you have for future research as a result of this work?

Response: In this study, Clalit research institute team and collaborators from Northwestern University in Chicago utilized the Clalit Dataset, to create a comprehensive analysis of the impact of bariatric surgery on survival. These results are reassuring, and we will now turn to study in depth each specific outcome and the potentially differential impact on these outcomes including mortality on specific population sub-groups, to reach further insights and inform local and global polic Is there anything else you would like to add?

Response: In addition to the analyzed mortality data, exploratory data was also published and demonstrated the benefit of bariatric surgery with respect to BMI reduction, diabetes remission and incidence, and hypertension remission and incidence.
