Landmark IFSO Global Registry Report published

The First IFSO Global Registry Report (2014) has been released at the 19th World Congress of IFSO in Montreal, Canada. Published by Dendrite Clinical Systems, under the auspices of the International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO), the publication reports data on baseline obesity-related disease, operation types, operative outcomes and disease status after bariatric surgery in over 100,000 patients accumulated from 25 local and national databases and registries from all over the world.


"Together with IFSO, we are delighted to publish this first report. I would like to thank all the contributors for submitting their data," said Dr Peter Walton, Managing Director of Dendrite. "I hope this publication will be the first in a series of ground-breaking reports that will record and analyse clinical outcomes that may be useful in promoting an increase in bariatric and metabolic surgery provision."


The report is the culmination of months of research and analyses from the IFSO Global Registry Pilot (IGRP), which was established in January 2014 to demonstrate that it is possible to merge and analyse bariatric and metabolic surgical data from different countries and centres.


Data collection


Data collection was made possible via Dendrite"s hybrid portals for direct "On-line data entry" and "Upload-My-Data" for online electronic submission.


"On-line data entry" is an online database portal accessible over the Internet that enables surgeons/data managers to enter cases (with anonymised patient identifiers) using a simple on-line data form with just 4 pages of questions (typically takes just 3-4 minutes to complete per patient record). Centres from France, India, Peru, Saudi Arabia and Spain, submitted data using the "On-line data entry" portal.


The Dendrite team also designed and created a dedicated "IFSO Upload-My-Data" web portal. This platform is a proven interface designed to enable a community of surgeons or physicians to create a national or international database; even if there are different database systems at the local level, the data from each can be integrated into the central, merged registry.


The platform has been successfully utilised in a number of other national and international registries (for cardiac surgery, thoracic surgery) and has been specifically tailored for the IFSO project to enable both individual centres and national registries to submit data in batches on-line. Centres from Brazil, Canada, Chile, China, France, Germany, India, Italy, Mexico, Russia, Spain, Sweden, Taiwan, The Netherlands, United Kingdom and the UAE, submitted data using the "IFSO Upload-My-Data" web portal.


"Our two data submission portals have clearly the demonstrated that data from different countries, database systems and centres can be collected, merged and analysed, and the outcomes published," added Dr Walton. "This pilot project is the first step in enabling the IFSO community to create an international database for all bariatric and metabolic surgeons."


Outcomes


The report includes 100,092 operation records from 18 countries and from five continents, and has detailed information on 65,636 gastric bypass operations (65.6% of the total operations submitted), 16,735 sleeve gastrectomy operations (16.7%) and 12,365 gastric banding operations (12.4%).


"The report provides fascinating county-to-country and region-to-region comparisons, as well as demonstrating the safety and effectiveness of bariatric and metabolic surgery on a global scale," commented Professor Michel Gagner, IFSO Council Member and IFSO 2014 Congress President.


On a country basis, there are marked differences in procedure type with centres submitting data from Mexico (92.2%), the Netherlands (94.0%) and Sweden (96.3%) recording the highest proportion of gastric bypass operations and those submitting data from Peru (100.0%), Saudi Arabia (100.0%) and India (91.1%) recording the highest proportion of sleeve gastrectomy surgery.


"I applaud this first report of the IFSO Global Bariatric Surgery Registry. It marks an historic first step in bringing together real world data from around the globe. It will provide essential support in understanding risk stratification, and refining those most likely to benefit from surgery," Professor John Dixon writes in the report. "It will allow new procedures to be assessed, devices to be tracked, and provide information regarding surgical learning curves, and may define minimal surgical loads for surgeons and their institutions.


The Global IFSO Registry Pilot Project was headed by Mr Richard Welbourn (UK), Dr Ingmar Naslund (Sweden), Dr Johan Ottosson (Sweden), Professor Michel Gagner (Canada) and Dr Peter Walton (Dendrite Clinical Systems).
