Introduction: Various definitions for bariatric surgery (BS) success exist, with weight loss and comorbidity resolution outcomes being the most prominent. The study’s aim was to compare how various healthcare professionals perceive success in BS. Methods: A 29-item, 10-point Likert scale online survey was distributed via email to Israeli healthcare professionals involved in the different BS aspects using common national professional organizations. These included bariatric surgeons, dietitians, social workers, psychologists, psychiatrists, primary care physicians, gastroenterologists, and nurses. Statement relevancy to BS success was rated. An item was classed as “very important” for BS success if at least 70% of participants rated it 8 or higher in each subgroup. Inter-observer agreement was calculated using kappa statistics. Data on specific occupation, years-in-practice, and major workplace were collected as well. Results: A total of 155 responses was obtained. The majority of respondents were dietitians (34.8%, n = 54), followed by bariatric surgeons (31.0%, n = 48) and nurses (14.8%, n = 23). Most respondents work mainly at public hospitals (32.9%, n = 51), followed by private hospitals (26.5%, n = 41). The mean years-in-practice among all healthcare professionals was 8.5 ± 8.5 years. Overall inter-observer agreement for prioritized items in accordance to BS success among all health professional subgroups was fair (Fleiss kappa = 0.278, P < 0.001), while dietitians and mental health specialists showed the highest agreement rate (Cohen’s kappa = 0.592, P < 0.001). Conclusion: The study highlights the various views on defining BS success by different healthcare professionals, although there was some overlap of core outcomes prioritized by all professionals. International uniform definitions for BS success are required.
