Patient complaints following bariatric surgery 2012-18

We examined complaints submitted to the Norwegian System of Patient Injury Compensation (NPE) following bariatric surgery, including the background for the complaint, the proportion of patients whose complaints were upheld, and the characteristics of complaints that were upheld.

All complaints relating to bariatric surgery performed in the period 2012-18 were reviewed and categorised according to symptoms, findings and events relevant to the outcome of the complaint. Anonymous summaries from the experts' statements were reviewed and categorised according to year of decision, gender, age, basis for compensation or rejection, and whether the intervention was carried out in the public or private health service.

Forty-four (26 %) of a total of 171 applications for patient injury compensation were upheld. These applications represented 25 patients who had surgery in the public health service (19 % upheld) and 19 patients who were operated on in the private health service (51 % upheld). The single most common reason for a complaint being upheld (n = 18) was lack of indication for bariatric surgery.

More post-bariatric surgery complaints were upheld for lack of indication than for surgical errors. Proper patient selection, good preoperative preparation, good information and shared decision-making are important factors for achieving the best possible bariatric surgery outcome. An interdisciplinary team that monitors patients over time can help ensure the quality of the entire treatment chain.
