The impact of a bariatric rehabilitation service on weight loss and psychological adjustment--study protocol.

BACKGROUND: Bariatric surgery is currently the most effective form of obesity management for those whose BMI is greater than 40 (or 35 with co morbidities). A minority of patients, however, either do not show the desired loss of excess weight or show weight regain by follow up. Research highlights some of the reasons for this variability, most of which centres on the absence of any psychological support with patients describing how although surgery fixes their body, psychological issues relating to dietary control, self esteem, coping and emotional eating remain neglected.The present study aims to evaluate the impact of a health psychology led bariatric rehabilitation service (BRS) on patient health outcomes. The bariatric rehabilitation service will provide information, support and mentoring pre and post surgery and will address psychological issues such as dietary control, self esteem, coping and emotional eating. The package reflects the rehabilitation services now common place for patients post heart attack and stroke which have been shown to improve patient health outcomes. METHODS/DESIGN: The study is a randomised control trial and patients will be allocated to receive either usual care or the bariatric rehabilitation service pre and post bariatric surgery. Follow up measures of weight loss and psychological issues will be taken at baseline (2 weeks preoperatively), 3, 6 and 12 months postoperatively. The contents of the bariatric service and the follow up measures are based on previous pilot work and have been developed further by the research team working closely with two patient support groups (BOSPA & WLSinfo). This study will take place in St Richard's Hospital in Chichester in the UK. DISCUSSION: It is predicted that a bariatric rehabilitation service will improve weight loss following surgery and will also facilitate changes in other psychological variables such as quality of life, dietary control, self esteem, coping and emotional eating. This also has cost implications for the NHS and other healthcare providers as improved effectiveness of bariatric surgery reduces the health costs of obese patients in the longer term.

Regional Variation in Unmet Need for Metabolic Surgery in England: a Retrospective, Multicohort Analysis.

Metabolic surgery provision is severely limited despite extensive supportive trial evidence. This study estimated the eligible population and the unmet need for metabolic surgery within English regions. Health Survey for England, National Diabetes Audit and population estimates were used to estimate the metabolic surgery eligible population by English region. Hospital Episode Statistics data was examined for metabolic surgery procedure volume by region (2013-2019). Regression analysis examined factors associated with metabolic surgery eligibility. 7.3% of the English population is potentially eligible for metabolic surgery; equivalent to 3.21 million people. Only 0.20% of the eligible English population receive metabolic surgery per year (regional variation 0.08-0.41%). The metabolic surgery eligible population was more likely to be female, older, have fewer educational qualifications and live in more deprived areas.

Systematic Review and Meta-Analysis of the Impact of Bariatric Surgery on Lower Urinary Tract Symptoms in Males.

BACKGROUND: Obesity is a chronic disease with multisystem morbidity. There are multiple studies reporting the effect of bariatric surgery on cardiovascular and metabolic disease, but few examine its impact on lower urinary tract symptoms. This article aims to perform a systematic review with meta-analysis, to determine the effects of bariatric surgery on lower urinary tract symptoms in male patients. METHODS: Medline, Embase, conference proceedings, and reference lists were searched for studies reporting the quantitative measurement of lower urinary tract symptoms score pre- and postweight loss surgery. The primary outcome was International Prostate Symptom Score (IPSS) before and after bariatric surgery. Secondary outcomes were changed in body mass index (BMI) and total body weight (TBW). Weighted mean differences (MD) were calculated for continuous outcomes. RESULTS: Seven studies were included in the analysis of 334 patients undergoing bariatric surgery. Mean study follow-up was between 3 and 36 months. IPSS score ranged from 3-12.7 preoperatively and 1.9-6.9 postoperatively. There was a statistically significant improvement in the IPSS score following bariatric surgery (MD 2.82, 95% CI 0.96 to 4.69, p=0.003). Bariatric surgery also resulted in statistically significant reduction of BMI and TBW. CONCLUSION: Bariatric surgery produces a significant improvement on lower urinary tract symptoms in men with obesity. This may be due to improvement of insulin sensitivity, testosterone levels or lipid profile associated with weight loss.

A Meta-analysis of the Impact of Bariatric Surgery on Back Pain.

BACKGROUND: The functional aspects of obesity are increasingly recognised as a significant clinical and public health concern. Whilst there is substantial evidence for the beneficial impact of bariatric surgery on metabolic and cardiovascular disease, there is less understanding of the quantitative effect of bariatric surgery on back pain. The aim of this meta-analysis was to assess the impact of bariatric surgery on back pain in reported studies. METHODS: Medline, Embase, conference proceedings and reference lists were searched for studies assessing quantitative back pain scores both before and after bariatric surgery. The primary outcome was visual analogue score for back pain pre- and post-bariatric surgery. Secondary outcomes were change in BMI, SF-36 quality of life scores and Oswestry Disability Index (ODI) scores. Weighted mean differences (MD) were calculated for continuous outcomes. RESULTS: Seven studies were included in the analysis of 246 patients undergoing bariatric surgery. Mean study follow-up was between 3 and 24 months. There was a statistically significant reduction in visual analogue score for back pain following bariatric surgery (MD - 3.01; 95% CI - 4.19 to - 1.89; p < 0.001). Bariatric surgery also resulted in statistically significant improvements in BMI, SF-36 score and ODI score. CONCLUSIONS: Bariatric surgery produces significant and quantifiable reductions in back pain. This may be commuted through reductions in axial load or improved quality of life, but further studies will improve understanding and aid preoperative counselling.

The impact of psychological support on weight loss post weight loss surgery: a randomised control trial.

BACKGROUND: The purpose of the present study is to evaluate the impact of a health psychology-led bariatric rehabilitation service (BRS) on patient weight loss following bariatric surgery at 1 year. METHODS: A single-site open-randomised parallel group control trial based at St. Richard's Hospital in Chichester in the UK. Patients (n = 162) were recruited immediately prior to Roux-en-Y gastric bypass and randomly allocated to receive either treatment as usual (n = 80) or the BRS (n = 82). The BRS involved three 50-min one-to-one sessions with a health psychologist and provided information, support and mentoring pre and post surgery addressing psychological issues such as dietary control, self esteem, coping and emotional eating. Weight loss was assessed at 1 year. The key outcome variable was BMI and change in BMI. RESULTS: Follow-up weight was available for 145 patients. Intention-to-treat analysis (n = 162) using last measured weights showed that mean change in BMI by 1 year post surgery was -16.49. There was no significant difference between the two groups (control group = -16.37, 95 % CI = 15.15-17.57; intervention = -16.6, 95 % CI = 15.42-17.81; η p (2) = 0.001). Similarly, explanatory analysis (n = 145) showed a mean change in BMI of -17.17. The difference between the two groups was not significant (control group = -16.9, 95 % CI = 15.78-18.18; intervention = -17.35, 95 % CI = 18.5-16.16; η p (2) = 0.001). CONCLUSIONS: Psychological support pre and post bariatric surgery had no impact on weight loss as measured by BMI and change in BMI by 1 year. It is argued that psychological support should be targeted to patients who start to demonstrate weight regain at a later stage. TRIAL REGISTRATION: ClinicalTrials.gov NCT01264120.
