Lack of Adherence to Follow-Up Visits After Bariatric Surgery: Reasons and Outcome

Abstract

Background A substantial number of patients undergoing bariatric surgery are lost to follow-up for unknown reasons, which may cause an overestimation of the benefits of operation. The aim of this study was to identify the reasons of failure to attend controls after bariatric surgery and the relationship with poor weight loss. Methods A retrospective analysis of a prospective database including all patients undergoing bariatric surgery from January 2004 to February 2012 was performed. Nonadherence was defined as missing any scheduled control visit for more than 6 months. Contact was attempted (mail, telephone, and e-mail), and responders were requested to complete a questionnaire. Results Forty-six (17.5 %) out of 263 patients were considered nonadherent. Thirty-three (71.7 %) of these patients completed the questionnaire. The main reasons for nonadherence were work- (36.4 %) and family-related (18.2 %) problems or having moved outside the city or to the country (15.2 %). The percentage of nonadherent patients aged ≤45 years was greater as compared with those aged >45 years [28 (60.1 %) vs 18 (42.2 %), respectively, P = 0.034]. Likewise, of the 30 patients with unsuccessful weight loss (P = 0.046). Finally, 96.9 % of patients were completely satisfied with surgery and would recommend the procedure to other morbid obese patients. Conclusion The nonadherence rate to follow-up visits after bariatric surgery was 17.5 %, mainly associated with work-related problems. Nonadherence was greater in patients aged ≤45 years and in those with poor weight loss.
