Social History of Bariatric Surgery: Relationship to Patient and Associations with Postoperative Outcomes.

Purpose: There is limited research about the prevalence of patients initiating metabolic and bariatric surgery (MBS) who also know someone who had MBS, referred to as having a social history of MBS. Evidence about the specific relationship of these individuals to the patient, how having a social history of MBS is associated with patients' choice of surgical procedure, and how having a social history of MBS is associated with patients' postoperative outcomes can be used to inform future preoperative assessments. The objective was to (a) define the number of people patients knew who had MBS and relationship to patient, (b) assess congruence between those who had MBS with patients' procedure selection, and (c) explore associations between social history of MBS and postoperative outcomes.
