Co-Responsibility: Exploring the Impact of Patient-Partner Dynamics on Health Outcomes After Bariatric Surgery
BARIATRIC SURGICAL PRACTICE AND PATIENT CARE(2023)
Abstract
The social environment of patients undergoing bariatric surgery is gaining influence on health outcomes. This retrospective cohort study aims to develop a questionnaire measuring patient-partner co-responsibility and its association with postoperative health outcomes. Three hundred ninety patients undergoing bariatric surgery between 2015 and 2020 filled out a questionnaire, assessing co-responsibility, spousal support, and health outcomes such as weight loss, eating and exercise habits, and self-efficacy. Principal component analysis (PCA) was used for component identification and regression analysis to address the association between co-responsibility and health outcomes. PCA identified three components explaining 56.7% of variance: "Satisfaction with partner support," "Love and support," and "Desired co-responsibility," with high internal consistency, except for "Desired co-responsibility." Despite relatively high ratings of co-responsibility, prediction of patients' health outcomes was poor, explaining between 5% and 11% of variance in body mass index (BMI) reduction, weight loss, physical activity, and weight loss-related self-efficacy. Despite poor predictability, co-responsibility was consistently associated with health indices like BMI, weight, physical activity, eating habits, and self-efficacy. While the instrument needs refinement, it provides first insights for caretakers and adds a new angle to Patient Reported Experience Measures by taking a patient's social context out of the hospital into account.
