Objective:To provide evidence-based recommendations regarding the use of advanced technology in the management of persons with diabetes mellitus to clinicians, diabetes-care teams, health care professionals, and other stakeholders. Methods:The American Association of Clinical Endocrinology (AACE) conducted literature searches for relevant articles published from 2012 to 2021. A task force of medical experts developed evidence-based guideline recommendations based on a review of clinical evidence, expertise, and informal consensus, according to established AACE protocol for guideline development. MainOutcomeMeasures:Primary outcomes of interest included hemoglobin A1C, rates and severity of hypoglycemia, time in range, time above range, and time below range. Results:This guideline includes 37 evidence-based clinical practice recommendations for advanced diabetes technology and contains 357 citations that inform the evidence base. Recommendations:Evidence-based recommendations were developed regarding the efficacy and safety of devices for the management of persons with diabetes mellitus, metrics used to aide with the assessment of advanced diabetes technology, and standards for the implementation of this technology. Conclusions:Advanced diabetes technology can assist persons with diabetes to safely and effectively achieve glycemic targets, improve quality of life, add greater convenience, potentially reduce burden of care, and offer a personalized approach to self-management. Furthermore, diabetes technology canimprove the efficiency and effectiveness of clinical decision-making. Successful integration of thesetechnologies into care requires knowledge about the functionality of devices in this rapidly changingfield. This information will allow health care professionals to provide necessary education and training topersons accessing these treatments and have the required expertise to interpret data and makeappropriate treatment adjustments.

In 2012, an outstanding expert panel derived from IFSO-EC (International Federation for the Surgery of Obesity – European Chapter) and EASO (European Association for the Study of Obesity), composed by key representatives of both Societies including past and present pres- idents together with EASO’s OMTF (Obesity Management Task Force) chair, agreed to devote the joint Medico-Surgical Workshop of both institutions to the topic of metabolic surgery as a pre-satellite of the 2013 European Congress on Obesity (ECO) to be held in Liverpool given the extraordinarily advancement made specifically in this field during the past years. It was further agreed to revise and update the 2008 Interdisciplinary European Guidelines on Sur- gery of Severe Obesity produced in cooperation of both Societies by focusing in particular on the evidence gathered in relation to the effects on diabetes during this lustrum and the sub- sequent changes that have taken place in patient eligibility criteria. The expert panel compo- sition allowed the coverage of key disciplines in the comprehensive management of obesity and obesity-associated diseases, aimed specifically at updating the clinical guidelines to re- flect current knowledge, expertise and evidence-based data on metabolic and bariatric surgery.
