Résumé
Appraisal of the impact of Bariatric surgery on health related quality of life and work productivity in morbidly obese patients Background: In the last decades, morbid obesity has emerged as an increasingly prevalent chronic metabolic disorder affecting populations located in both developed and emerging countries. Obesity is associated with increased morbidity, disability and premature mortality. Given the impact of obesity on health status and its related economic burden, it is reasonable to anticipate that weight loss in obese patients will be associated with health and economic benefits. Bariatric surgery has emerged as a treatment of choice for this patient population. Significant reductions in mean percent excess weight loss and BMI percent change are observed as a consequence of Bariatric surgery. Several studies have established that obese individuals experience significant impairments in quality of life as a result of their condition. Health related quality of life (HRQoL) represents a particularly important and relevant outcome when assessing the overall impact of chronic conditions such as obesity. The data published as of date reports a significant correlation between excess weight loss and improvement in weight specific and physical aspects of HRQoL. However, trends toward decreases in HRQoL associated with weight regain between the first and sixth year post surgery have also been reported. The evidence relating to change in HRQoL in obese patients following Bariatric surgery for weight loss is currently either of relatively low quality or mainly focussed on evaluating the short-term impact of the intervention on HRQoL. Often overlooked but equally important is the relationship between obesity and its outcome on work productivity. Ample evidence underlining the correlation between obesity, increased work limitation and productivity loss may be found in the literature. The need for further evaluation of HRQoL and productivity loss outcomes over longer time horizons, following Bariatric surgery, has actually been identified as key areas of focus in this field of research, given the chronic nature of the disease and its considerable economic burden. Long-term outcomes data related to HRQoL and productivity loss following Bariatric surgery remains scarce in the Canadian setting. Objective: To describe the impact of Bariatric surgery on HRQoL and work productivity in patients with morbid obesity. Methodology: A cross-sectional survey measuring health related quality of life and work productivity outcomes, using the SF-36, the EQ-5D and the WLQ, for morbidly obese patients sampled from a population of patients being treated at the McGill University Health Centre (MUHC). Results: We observed Improvements in HRQoL and WLQ outcomes over the follow-up time period following Bariatric surgery and that, for all outcome measures. Conclusion: Following Bariatric surgery, patients may experience less physical disability and mental health issues and the perception of their health related quality of life state was reported to be significantly better than before the surgery. Per our findings, the initial positive impact of Bariatric surgery on HRQoL appeared to be sustained over time. Increases in physical disability, work limitations and decreases in patients' perception of their health status may be consequential to increments in BMI units and years of follow-up since the surgical intervention. Our findings further corroborated trends towards decreases in the occurrence of chronic comorbidities following Bariatric surgery.

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
