April 2017
Where is the study “Comparison of economic & clinical outcomes between patients undergoing lap bariatric surgery with Powered vs Manual Endo-staplers” was published?
Journal of Medical Economics (international peer-reviewed journal dedicated to the publication of high quality clinical, observational real-world health outcomes research)
What is the Premier Healthcare Database?
An independent database that is one of the largest statistically certified databases in the world, collecting data from more than 600 hospitals and representing 20% of all US inpatient hospital discharges.
When is this study “Comparative effectiveness assessment of two powered surgical stapling platforms in laparoscopic sleeve gastrectomy" published?
June 2020
Where is this study “Comparative effectiveness assessment of two powered surgical stapling platforms in laparoscopic sleeve gastrectomy" published?
Medical Devices & research (an international peer reviewed, open access journal that focuses on the evidence, technology, research and expert opinions)
How many patients were examined and what procedure did they undergo between year _____ &________?
31,000 lap bariatric surgery from 2012 & 2015
What are the parameters in measuring economic & clinical outcomes?
-Time (OR, hospital length of stay)
-Costs (to the hospital, medical/surgical supply, room, and board OR)
-Discharge status (discharge to home and non-home setting)
-Clinical (bleeding and OR transfusion)
-Readmissions (within 30,60,90 days post discharge)
What are the 2 analyses that the Journal of Medical Economics highlighted?
1. Powered vs Non-powered
2. Ethicon Powered vs Medtronic Non-Powered
What are the variables controlled with the study “Comparison of economic & clinical outcomes between patients undergoing lap bariatric surgery with Powered vs Manual Endo-staplers”?
1. Surgeon and hospital types (facility size, procedure volumes, teaching/ non-teaching)
2. Patient demographics (age, gender, patient type etc)
3. Clinical characteristics (BMI & comorbidties)
What is patient data used in the study “Comparative effectiveness assessment of two powered surgical stapling platforms in laparoscopic sleeve gastrectomy"?
Patients undergoing sleeve gastrectomy 2017-2018 atleast 21yrs of age, no robotic surgeries included and classified as having either GST or SIG based on records
What was the result when comparing powered vs non-powered?
24% reduction in rate of bleeding related complications
8% (USD1, 132) reduction to overall costs
What was the result when Ethicon powered vs Medtronic non-powered?
1. 47% reduction in rate of bleeding related complications
2. 13% (USD 1,777) reduction in overall costs
3. 14% reduction in OR time
What was the result of Ethicon Powered vs Ethicon non-powered?
1. 28% reduction in rate of bleeding related complications
2. No statistically significant difference in overall hospital costs
What was the result of Ethicon non-powered vs Medtronic non-powered?
1. No statistically significant difference vs bleeding 2. 15% (USD 2,179) reduction in overall costs
What is the conclusion of the study “Comparison of economic & clinical outcomes between patients undergoing lap bariatric surgery with Powered vs Manual Endo-staplers” was published?
Stapler choice matters and different staplers can be associated with clinical and economic outcomes in bariatric surgery which highlights the importance of tissue specific design Echelon Flex powered staplers.
What are the covariates measurement of the Signia evidence?
2. Clinical characteristics
3. Hospital provider
What is the result in terms of hemostasis related complications between Echelon Flex Powered Staples with TSG reloads VS Signia?
1. 73% reduction in the rate of hemostatis related complications compared to Signia stapling system with tri-staple
What is the cost results when comparing powered Echelon with GST reload vs Signia?
The use of GST was associated with a 7% lower median total hospital cost compared to Signia. $9,771.00 VS $10,487.00
What is the result of length of stay OR time and 30-60-90 day readmissions?
None of these results are statistically significant meaning we cannot claim any association between the device and the outcome.
No anastomotic leaks were identified in the group.
How would you reply to a surgeon when asked that this study is biased and is sponsored by Ethicon?
You can say analysis is based on Premier data which is independent and can be used by anyone.
Bariatric surgeons authors from around the world where a part of the study to ensure strict methodology and credibility.
This study has been published in a peer reviewed journal which demonstrate it has help up to the review of scientific community.
