Brief 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.

Outcome Measures

Primary Outcomes (1)

  • Modified King's Score (comparison between intervention group I and control group I resp. intervention group II and control group II)

    Primary endpoint will be the difference in the modified King's Score between intervention group I and control group I resp. intervention group II and control group II. The modified King's Score is a multifaceted sum score taking into account categories A to L (airways, BMI, cardiovascular, diabetes mellitus, economic, functional, gonadal/sexuality, health status, body image, junction (gastroesophageal), kidney, liver). For each category patients receive between 0 and 3 points describing the degree of impairment (0 Points: normal; 3 Points: severe impairment); the minimum score can be 0, maximum sum score can thus be 36.

Study Arms (4)

Early aftercare (intervention group 1)

EXPERIMENTAL

Patients in this group will begin the ACHT program immediately after their bariatric metabolic operation. 3 weeks post surgery, they will attend the initial examination and meet their case manager. The obesity guide will then set up an electronic case file for the patient and introduce the patient to the obesity app. Through the next 18 months the obesity guide will monitor the patient's therapeutic success and adherence to the therapeutic goals. In month 2 patients visit a sports physician who assesses their mobility and physical capacity to compile a personal training plan, which will be uploaded onto the patient's case file and thus be available to the patient via the app. In months 3,6,9.12 and 18, patients will attend their aftercare appointments at specially trained ACHT physicians, where they will be physically examined by a physician and receive tailored dietary advice from a nutritional advisor. In month 18 patients revisit the surgical centre for the follow-up examination

Other: early aftercare

Mid-term to long-term aftercare (intervention group 2)

EXPERIMENTAL

Patients in this group first visit the study center 18 months after their bariatric surgery for the initial examination and start the program in month 19 post-op. At the center, they will meet their obesity guide who will set up an electronic case file for the patient and introduce the patient to the obesity app. Throughout the next 18 months, the obesity guide will monitor the patient's therapeutic success and adherence to the therapeutic goals. In month 19 post-surgery, patients visit a sports physician who assesses their mobility and devises a personal training plan. This plan will be uploaded onto the patient's case file and made available to the patient via the app. In months 19,21,24, 30 and 36, patients attend their aftercare appointments at specially trained ACHT physicians, where they will be physically examined and receive tailored dietary advice. In month 36, patients will be reexamined at the study center.

Other: mid-term to late aftercare

control group 1 (early aftercare)

NO INTERVENTION

Analogous to intervention group I, patients in this group are invited to the study center after verbal and written information. These patients will attend the one-off evaluation examination (18 months after the operation) at the obesity centre. If interested, patients in this group can be included in intervention group II until the required number of cases (140 patients) has been reached.

control group 2 (mid-term to long-term aftercare)

NO INTERVENTION

Analogous to intervention group II, patients in this group are invited to the study center after verbal and written information. These patients will attend the one-off evaluation examination at the study center 36 months after the operation.

Interventions

This group begins the aftercare program immediately after their bariatric surgery.

Early aftercare (intervention group 1)

This group begins the aftercare program 18 months post surgery.

Mid-term to long-term aftercare (intervention group 2)
