Study design and participants
BaSE was a multicenter and randomized controlled efficacy trial in adult patients who underwent bariatric surgery. In 2009 the study was established at the University Hospital of Heidelberg, University Hospital of Tübingen, and the Hospital Sachsenhausen, Frankfurt, Germany. Between May 2009 and November 2012, we included 117 patients from the 3 surgical departments. Inclusion criteria were adult patients aged≥18 years; severe obesity (BMI≥40 kg/m2 or BMI≥35 kg/m2 with somatic co-morbidities);
Participant characteristics
Of 306 patients approached for the trial, 49 did not meet the eligibility criteria, 95 met at least one exclusion criterion, and 45 patients declined to participate; eventually 117 patients were included in the study. One year after surgery (end of study) 7 patients (6%) were lost to follow-up. Three patients were excluded from the ITT analysis: 1 had not undergone bariatric surgery, and for 2 patients only baseline values were available.
Rates of loss to follow-up did not differ between the
Discussion
To our knowledge, the BaSE study is the first multicenter RCT investigating the effect of a 1-year multidisciplinary psychoeducational program aimed at improving weight loss and psychosocial factors in patients following bariatric surgery. Results of our study provide important and necessary evidence because for many years clinicians, researchers, and health insurers have debated the presumed necessity of a postoperative intervention program.
In summary, patients in our study had reduced their
Conclusion
Results of our RCT study indicate that a videoconferencing-based psychoeducational program is effective for the subgroup of patients with depressive symptoms at baseline. Therefore, the challenge is to detect the patients at risk for psychological complications and noncompliance and to treat them appropriately. As a conclusion of the BaSE study we therefore suggest a stepped care approach for bariatric surgery patients. In the first year, all patients could be monitored at a very low level.
