The Bariatric Surgery Registry

Persons with obesity are more likely to suffer from many other serious health conditions and are more likely to die young. Lifestyle interventions have not been found to be an effective long-term solution for treating obesity. When usual weight loss measures are not successful, bariatric, or 'weight loss,' surgery may be considered. Bariatric surgery is performed to help people with obesity achieve weight loss which they can maintain. Weight loss following bariatric surgery leads to improvement in health and well-being, and patients have been shown to live longer. It is invasive surgery which has surgical risks and potential side effects, including death. Since people are having this surgery to improve their health, it is important that the surgery is performed with a minimum of side effects, otherwise it cannot be justified. Information is collected about the surgery, any complications after the surgery, weight at various time points, and if the patient has diabetes and how it is is treated. Patient details are needed to be able to identify patients on the registry and track their progress through data linkages. Participants have information about their bariatric surgery provided to the registry by their surgeon or hospital. They may also be contacted directly by the registry staff to see if they had any complications and if the surgery had any effect on their health (if they have diabetes), weight, and well-being. The Registry will hold their identifiable information as it aims to follow each patient for ten years after their first bariatric operation. By systematically collecting information on every procedure performed in Australia and New Zealand, the registry will help to identify when surgeons, hospitals or procedures not performing to the expected standard. A Bariatric Surgery Registry should also be able to demonstrate how effectively bariatric surgery results in weight loss and improved health (using diabetes as a marker of health) across the two countries.

The Bariatric Surgery Registry (BSR) is a population based observational quality improvement study of patients with obesity undergoing bariatric surgery and collects identifiable data obtained from participants' medical records, the participants themselves and from surgeons or hospitals. When mature, the registry will collect data from all public and private hospitals in Australia and New Zealand that perform bariatric surgery (estimated to be around 152 sites in Australia and 12 in NZ). Contributing surgeons or public hospital clinics are required to make patients who will undergo bariatric procedures aware that information related to their procedure will be provided to the BSR. Surgeons and public hospital clinics are required to display a poster that advises their practice/clinic contributes to the Bariatric Surgery Registry and give all bariatric patients a registry information flyer. Upon the registry receiving patient demographic and procedure information from the surgeon or the hospital, bariatric patients are posted a Participant Fact Sheet (PFS) further advising that participation in the registry is voluntary and their decision not to participate in the registry or to participate and later opt out, will not affect their relationship with their treating surgeon or the hospital, and their surgeon will be unaware of their participation status. After the PFS are posted, bariatric patients have two weeks to contact the Registry staff via the free call telephone number to opt out. Their participation will be presumed if no contact is made within that period. There are three options for participation: full participation; partial opt out - data is included on the registry but registry staff will not contact the participant during the follow-up period; or, complete opt out - no clinical data is included on the registry. All participants retain the right to opt out at any time. For those who choose to opt out, their information is disposed of in accordance with the National Statement for Ethical Conduct in Human Research 2007 (2015). Data are provided using one of the following options: web browser with secure authorised entry using the Bariatric Surgery Registry Interface (BSR-i); paper based data forms securely faxed or posted; or, secure electronic record transfer from surgeons' or hospitals' electronic medical record. In New Zealand, data will only be collected through direct entry through the BSR-i. Completeness and accuracy of the eligible population captured by the Registry will be assessed using hospital International Classification of Disease 10-Australia Modified (ICD-10-AM) codes. Cross-checking with ICD-10-AM codes allows for complete data capture at each hospital site and provides data validation for each procedure submitted by the surgeon. Hospital Information Services (HIS) at each hospital site or of a private hospital group provide regular ICD-10-AM coding reports for bariatric procedures performed by surgeons who participate in t Покажи пълното описание...
