adipositas care & health therapy

Conditions: Patients After Metabolic-bariatric Surgery; Obesity, Morbid

Summary: acht - adipositas care and health therapy - is a structured, digitally-supported, cross-sectoral and close to home program developed for the postoperative care of patients following obesity surgery. the aim is to ensure the long-term success of therapy following bariatric surgery. acht was selected by the federal joint commission for support under the innovation fund. the project started in july 2019 and will end in december 2022.

in germany, every second adult is overweight and almost one in four is obese - the trend is rising. obesity is a chronic illness which significantly increases the risk of developing co-morbidities such as cardiovascular and joint diseases, cancer and diabetes. in addition to those functional and health limitations, many people are stigmatised which can lead to social exclusion and a reduced quality of life. available conservative therapies do not always lead to sufficient, long-term weight loss. in those cases and if the disease is very pronounced, an obesity surgery (bariatric-metabolic surgery) can help. in order to ensure its success, patients require long-term after care following surgery. currently, there are no necessary outpatient care standards and provisions. inpatient obesity centres try to compensate for this with their own structures and limited resources, but are already reaching their limits. the aim of the acht project is to ensure long-term therapeutic success after an operation. this is done through a digitally supported, structured, cross-sectoral and close-to-home aftercare program. obesity case managers (obesity guides) coordinate the aftercare process and monitor the therapy goals. a digital case file links patients, case managers, resident doctors and obesity centers. individual exercise goals, nutritional advice and psychological support are part of acht. acht is connected to quality assurance measures of a medical society. four groups are compared in the acht study. one group begins their 18 months acht aftercare program directly after the operation, another group 18 months after the operation. these two groups are compared to patients who receive standard care. through these two intervention groups, we hope to examine the long-term effects of the program within the given time constraints of the study. acht is funded for three and a half years by the federal joint committee as part of the innovation fund with approx. 4.5 million euros.
