The study objectives were to assess 2-year changes in health-related quality of life ( HRQL ) after gastric bypass in patients with severe obesity and to analyze HRQL improvements in relation to weight loss after bariatric surgery . This was a prospect i ve intervention study with consecutive patients referred to two bariatric surgical units in the Basque Country . We used both generic ( Short Form Health Survey , SF-36 and EuroQol , EQ-5D ) , and specific question naires ( Moorehead-Ardelt , MA II and Obesity-related Problems Scale , OP ) . Effect sizes and receiver operating characteristic ( ROC ) curves were calculated to assess the change in quality of life . Spearman ’s correlation coefficient was calculated to assess whether there was an association between changes in body mass index ( BMI ) and HRQL . Of 82 patients who underwent surgery , 79 were followed-up for 2 years . Mean weight loss was 37 % of body weight ( 49 kg ) and BMI fell from 50.6 to 31.8 . The initial problems and final improvements were greater in the physical dimensions . Considerable benefits were observed in assessment s with all the instruments used . However , the changes in weight/ BMI and HRQL were not linear . The comparison with general population showed a similar profile in SF-36 dimensions after surgery . Severely obese patients have lower perceived health across all dimensions of quality of life . Moreover , the impact on functioning is so important that severe obesity can be described as a cause of disability that disappears 2 years after surgical treatment . ROC curves indicate that most of the HRQL measures are poor predictors of change in terms of reduction in body weight or BMI Background Although obesity surgery is currently the most effective method for achieving weight loss , not all patients lose the desired amount of weight and some show weight regain . Previous research shows that successful weight loss may be associated with the amount of investment the patient feels that they have made in their operation . For example , those who feel that it has taken more time and effort to organise , has cost more money , has been more disruptive to their lives and has caused pain are more likely to lose weight after their operation . Therefore , it seems as if the greater the sense of investment , the greater the motivation to make the operation a success . The present study aims to build on these findings by encouraging weight loss surgery patients to focus on the investment they have made , thus making their investment more salient to them and a means to improve weight loss outcomes . Methods The study involves an open r and omised parallel group control trial with patients allocated either to the control or investment intervention group . Using third party blinded r and omization , half the patients will be asked to rate and describe the investment they have made in their operation just before surgery then 3 and 6 months after surgery . All patients will record their weight , beliefs about food , intentions to change and actual eating and exercise behaviour at baseline then 3 , 6 and 12 months follow up . Patients will be recruited from the bariatric surgery pre- assessment clinic at University College Hospital , London . The primary outcome is to explore the impact of the investment based intervention on patient ’s weight and BMI , with secondary outcomes of patients ’ beliefs about foods , behavioural intentions and diet and exercise behaviours . Discussion It is predicted that the investment intervention will improve excess weight loss post-surgery , together with beliefs about food , intentions to change and actual change in diet and exercise behaviour . This has cost implication s for the NHS and other healthcare providers as improved effectiveness of bariatric surgery reduces the health costs of obese patients in the longer term and this simple , easy to administer and low cost intervention could become routine practice for bariatric patients .Trial registration Clinical Trials.gov identifier NCT02045628 ; December 2 , 2013 Outcome reporting in  bariatric surgery  needs a core outcome set ( COS ) , an agreed minimum set of outcomes reported in all studies of a particular condition . The aim of this study was to summarize outcome reporting in bariatric surgery to inform the development of a COS . Outcomes reported in r and omized controlled trials ( RCTs ) and large non-r and omized studies identified by a systematic review were listed verbatim and categorized into domains , scrutinizing the frequency of outcome reporting and uniformity of definitions . Ninety studies ( 39 RCTs ) identified 1,088 separate outcomes , grouped into nine domains with most ( n = 920 , 85 % ) reported only once . The largest outcome domain was ' surgical complications ' , and overall , 42 % of outcomes corresponded to a theme of ' adverse events ' . Only a quarter of outcomes were defined , and where provided definitions , which were often contradictory . Percentage of excess weight loss was the main study outcome in 49 studies , but nearly 40 % of weight loss outcomes were heterogeneous , thus not comparable . Outcomes of diverse bariatric operations focus largely on adverse events . Reporting is inconsistent and ill-defined , limiting interpretation and comparison of published studies . Thus , we propose and are developing a COS for the surgical treatment of severe and complex obesity OBJECTIVE To test the effectiveness of two levels of physical activity interventions before and up to 6½ months after bariatric surgery . METHODS Before surgery , individuals completed submaximal exercise testing on a treadmill . After r and om assignment to st and ard care , pedometer use , or exercise counseling plus pedometer , participants wore an accelerometer for approximately 2 weeks and returned it to the bariatric center before surgery and 2 , 4 , and 6 months postoperatively . RESULTS Individuals in exercise counseling plus pedometer had higher steps per day and bout minutes of exercise per week than st and ard care and pedometer use over the course of the study . There were no group differences related to exercise tolerance ; however , all groups made significant improvement . There was no statistically significant change in sedentary or light activity nor was there a difference between groups . CONCLUSIONS Exercise counseling using pedometers increases physical activity from the perioperative period to 6½ months after surgery , but providing pedometers without professional feedback may not be more effective than st and ard bariatric surgery treatments . Rapid weight loss increases exercise tolerance and may mask the fitness improvements achieved through a modest physical activity intervention during the first 6 months after bariatric surgery OBJECTIVE To examine the responsiveness of the 36-Item Short Form Health Survey ( SF-36 ) to clinical changes in three surgical groups and to study how health-related quality of life ( HRQL ) changes with time among patients who undergo total hip arthroplasty , thoracic surgery for treatment of non-small-cell lung cancer , or abdominal aortic aneurysm ( AAA ) repair . DESIGN Prospect i ve cohort study with serial evaluations of HRQL preoperatively and at 1 , 6 , and 12 months after surgery . SETTING University tertiary care hospital . PATIENTS Of 528 patients , more than 50 years of age , who were admitted for these elective procedures , 454 ( 86 % ) provided preoperative health status data and are members of the study cohort . At 12 months after surgery , 439 ( 93 % ) of the cohort was successfully contacted and 390 ( 90 % ) provided follow-up interviews . MEASUREMENTS AND MAIN RESULTS The Medical Outcomes Study SF-36 , the Specific Activity Scale , five vali date d health transition questions , and a 0 to 100 scale measure of global health were used to assess changes in health status at 1 , 6 , and 12 months after surgery . Change in health status as measured by the SF-36 demonstrated that physical function and role limitations due to physical health problems were worse 1 month after these three surgeries . However , by 6 months after surgery , most patients experienced significant gains in the majority of the dimensions of health , and these gains were sustained at 12 months after surgery . Longitudinal changes in the SF-36 were positively associated with responses to the five health transition questions , to changes on the Specific Activity Scale and global health rating question , and to clinical parameters for persons who had AAA repair . These findings indicate that the SF-36 has evidence of validity and is responsive to expected changes in HRQL after elective surgery for these procedures . CONCLUSIONS For the total hip arthroplasty patients , responsiveness was greatest for the SF-36 scales that measure physical constructs . However , for the two other procedures and at various points of recovery , significant changes were observed for all eight subscales , suggesting that responsiveness was dependent on the type of surgery and the timing of follow-up , and that multidimensional measures are needed to fully capture changes in HRQL after surgery Background : The Bariatric Quality of Life Index ( BQL ) was created and vali date d as a nine-factor model in 2005 for the measurement of quality of life (QoL)in  patients before and after bariatric surgery .  Even though the results were acceptable , the statistical structure of the test was very unclear . Methods : A total·f466 patients were enrolled in an ongoing prospect i ve longitudinal German study . The assessment took place preoperatively and at 1 , 3 , 6 , 9 , and 12 months postoperatively . After that period , reevaluations were done on a yearly basis . In addition to demographic and clinical data , QoL data were collected using the  BQL  , the Short Form12 ( SF-12v2 ) , the Gastrointestinal Quality of Life Index ( GIQLI ) , and the  Bariatric Analysis and Reporting Outcome System  ( BAROS ; old version since the study started in 2001 ) . Statistical parameters for contingency ( Cronbach ’s Α),construct and criterion validity ( Pearson ’s r ) , and responsiveness ( st and ardized effect sizes ) were calculated . The data of the assessment s conducted preoperatively and after 6 and 12 months were used for the validation . Results : The factor analysis and the screeplot showed that a one-factor solution explained 45.37%of variance . The selectivity of the items ranged between 0.61 and 0.85 , and Cronbach ’s Α was 0.898 . The measurements showed similar excellent results with the analysis of all measurement points . Pearson ’s test showed a good retest reliability ( r = 0.9 ) . The correlations with the SF-12 and the Moorehead-Ardelt I question naire ( MA-I ) were significant , while the correlation with the GIQLI was low . The results of the correlation with the excess weight loss (EWL)(0.45 and 0.49 ) and the BMI ( –0.38 and –0.47 ) were good . Conclusion : The BQL is a valid instrument and should be preferred over generic question naires as it provides betterresponsiveness Background Gastric b and ing remains a common procedure worldwide . Improving health-related quality of life ( HRQOL ) has become a major goal in the treatment of patients with chronic diseases , yet there are few comprehensive data regarding the effect of gastric b and ing on HRQOL . The aim of this study was to evaluate the impact of laparoscopic gastric b and ing on HRQOL with particular regard to change over time . Methods The 262 consecutive patients included between May 2005 and September 2006 in a French multicenter prospect i ve study design ed to assess the safety and efficacy of a  gastric b and were asked to complete the SF36 question naire preoperatively and each 6 months during 3 years . The HRQOL scores were compared with community norms , and their longitudinal change was assessed using cross-sectional analysis and mixed-effects linear modeling ( individual growth model ) . Results One hundred sixty-four patients ( 63 % ) provided a preoperative and at least one postoperative SF-36 question naire from 12 to 36 months and form the basis of the present study . In all dimensions , the scores of HRQOL were significantly impaired preoperatively and were significantly improved at 3 years . The increase in HRQOL scores was most marked during the first postoperative months ; it continued more slowly after 6 months and stabilized after 1 year . The improvement in HRQOL was associated with the decrease in BMI , in all dimensions . Conclusion Gastric b and ing results in a significant improvement in HRQOL . A return to normal can be expected at 1 year and persists at 3 years . The postoperative improvement in HRQOL is strongly related to weight loss OBJECTIVE Bariatric surgery is an effective method for acute weight loss . While the impact of bariatric surgery on general medical conditions ( e.g. , type 2 diabetes ) is well documented , few studies focus on physical functional outcomes following weight-loss induced by bariatric surgery . DESIGN AND METHODS We report on 50 women aged 20 - 74 scheduled for Roux-en-Y gastric bypass ( RYGB ) procedure who were enrolled for a prospect i ve 1-year study . Height , weight , and waist circumference were recorded preoperatively and at 6 and 12 months , postoperatively . To track musculoskeletal/physical function changes , the  timed-get-up- and -go ( TGUG ) and short-form health survey-36 ( SF-36 ) and short musculoskeletal function assessment ( SFMA ) question naires were administered . RESULTS Patients had significant weight loss and functional improvement . At 1 year mean weight loss was 48.5 kg and mean TGUG improvement was 3.1 s. SMFA and SF-36 also showed improvement in functional components with weight loss at 6 months and 1-year post surgery . Significant associations were observed between TGUG and SMFA measures at all time points . Final weight at 1 year post bariatric surgery was also significantly correlated with most functional outcomes and changes in these outcomes . Partial correlations controlling for age revealed additional associations between body weight and functional outcomes , especially at the 6-month visit . CONCLUSION Our results suggest that significant rapid weight loss , such as that attained by bariatric surgery , acutely improves musculoskeletal function in morbidly obese patients . Additionally , for patients with musculoskeletal disease or injury , weight loss result ing from bariatric surgery may serve as an adjunct for improving global functional outcome , and enhancing the rehabilitation potential Outcome scores are very useful tools in the field of spinal surgery as they allow us to assess a patient ’s progress and the effect of various treatments . The clinical importance of a score change is not so clear . Although previous studies have looked at the minimum clinical ly important score change , the degree of score change varies considerably . Our study is a prospect i ve cohort study of 193 patients undergoing discectomy , decompression and fusion procedures with minimum 2-year follow-up . We have used three st and ard outcome measures in common usage , the oswestry disability index ( ODI ) , the  low back outcome score ( LBOS ) and the visual analogue score ( VAS ) . We have defined each of these scores according to a global measure of outcome grade d by the patient as excellent , good , fair or poor . We have also grade d patient perception and classified excellent and good as success and fair and poor as failure . Our results suggest that a median 24-point change in the ODI equates with a good outcome or is the minimum change needed for success . We have also found that different surgical disorders have very different minimal clinical ly important differences as perceived by patient perception . We found that for a discectomy a minimum 27-point change in the ODI would be classed as a success , for a decompression the change in ODI needed to class it as a success would be 16 points , whereas for a fusion the change in the ODI would be only 13 points . We believe that patient-rated global measures of outcome are of value and we have quantified them in terms of the st and ard outcome measures used in spinal surgery Background Patients undergoing bariatric surgery  generally report improved work performance after this procedure ; however , previous research has been limited by a lack of st and ardized employment measures and a failure to account for the impact of psychiatric illness on employment outcomes . To address these limitations , this study aims to assess changes in patients ’ employment impairment and productivity 12 months post-surgery and to identify psychosocial predictors of change in employment outcomes . Methods A total of 164 patients underwent bariatric surgery between February 2010 and November 2012 in this prospect i ve cohort study . The primary outcome was a change in employment impairment ( EI ) as measured by total Lam Employment Absence and Productivity Scale ( LEAPS ) scores and changes in participants ’ job status category . Multiple linear regression models assessed whether baseline demographic or clinical factors , including a history of psychiatric illness and changes in depressive , anxiety and quality of life ( QOL ) symptoms , were associated with a change in LEAPS scores . Results Participants reported a significant reduction in EI post-surgery ( p < 0.0001 ) and improvement in work productivity ( p < 0.0001 ) 12 months after surgery . Only changes in depression ( confidence interval ( CI ) 0.46 , 0.76 , p < 0.0001 ) , anxiety ( CI 0.49 , 0.85 , p < 0.0001 ) and mental QOL ( CI −0.30 , −0.17 , p < 0.0001 ) were significant predictors of change in EI total scores . Logistic regression analysis did not identify significant predictors of change in participant job status . Conclusions Patients with pre-bariatric surgery psychiatric distress are more likely to report greater employment impairment and worse employment productivity pre-surgery . These patients also experience the greatest improvements in post-surgery employment functioning OBJECTIVE To examine the impact of a pre-bariatric surgery physical activity intervention ( PAI ) , design ed to increase bout-related ( ≥10 min ) moderate to vigorous PA ( MVPA ) , on health-related quality of life ( HRQoL ) . METHODS Analyses included 75 adult participants ( 86.7 % female ; BMI = 45.0 ± 6.5 kg m(-2 ) ) who were r and omly assigned to 6 weeks of PAI ( n = 40 ) or st and ard pre-surgical care ( SC ; n = 35 ) .  PAI received 6 individual weekly counseling sessions to increase walking exercise . Participants wore an objective PA monitor for 7 days and completed the SF-36 Health Survey  at baseline and post-intervention to evaluate bout-related MVPA and HRQoL changes , respectively . RESULTS PAI increased bout-related MVPA from baseline to post-intervention ( 4.4 ± 5.5 to 21.0 ± 21.4 min day(-1 ) ) versus no change ( 7.9 ± 16.6 to 7.6 ± 11.5 min day(-1 ) ) for SC ( P = 0.001 ) . PAI reported greater improvements than SC on all SF-36 physical and mental scales ( P < 0.05 ) , except role-emotional . In PAI , better baseline scores on the physical function and general health scales predicted greater bout-related MVPA increases ( P < 0.05 ) , and greater bout-related MVPA increases were associated with greater post-intervention improvements on the physical function , bodily pain , and general health scales ( P < 0.05 ) . CONCLUSIONS Increasing PA preoperatively improves physical and mental HRQoL in bariatric surgery c and i date s. Future studies should examine whether this effect improves surgical safety , weight loss outcomes , and postoperative The purpose of this study was to determine whether pre- to postoperative increases in physical activity ( PA ) are associated with weight loss and health-related quality of life ( HRQoL )  following bariatric surgery . Participants were 199 Roux-en-Y gastric bypass ( RYGB ) surgery patients . The International Physical Activity Question naire ( IPAQ ) was used to categorize participants into three groups according to their preoperative and /1-year postoperative PA level : ( i ) Inactive/Active ( < 200-min/week/>or=200-min/week ) , ( ii ) Active/Active ( > or=200-min/week/>or=200-min/week ) and ( iii ) Inactive/Inactive ( < 200-min/week/<200-min/week ) . The  Medical Outcomes Study Short Form-36 ( SF-36 ) was used to assess HRQoL. Analyses of covariance were conducted to examine the effects of PA group on weight and HRQoL changes . Inactive/Active participants , compared with Inactive/Inactive individuals , had greater reductions in weight ( 52.5 + /- 15.4 vs. 46.4 + /- 12.8 kg ) and BMI ( 18.9 + /- 4.6 vs. 16.9 + /- 4.2 kg/m(2 ) ) . Weight loss outcomes in the Inactive/Active and Active/Active groups were similar to each other . Inactive/Active and Active/Active participants reported greater improvements than Inactive/Inactive participants on the mental component summary ( MCS ) score and the general health , vitality and mental health domains ( P < 0.01 ) . Although the direction of causation is not clear , these findings suggest that RYGB patients who become active postoperatively achieve weight losses and HRQoL improvements that are greater than those experienced by patients who remain inactive and comparable to those attained by patients who stay active . Future r and omized controlled trials should examine whether assisting patients who are inactive preoperatively to increase their PA postoperatively contributes to optimization of weight loss and HRQoL outcomes Data -gathering instruments were used in a r and omized controlled trial , design ed to assess a structured preoperative educational program for elective surgical patients . The key dependent variable was the physical functional capacity of patients following surgery . Question naires were developed to measure physical functioning in the immediate postoperative period , after discharge from hospital , and 10 days and 33 days after surgery . Statistical techniques used to measure interobserver agreement and bias were Bowker 's chi square , Cicchetti 's statistic , the contingency coefficient , Kendall 's Taub , and Kendall 's coefficient of concordance W. The st and ardized question naires permitted classification of patients ' postoperative physical functions with results that agreed highly with the classification done by experienced clinicians who cared for the same patients BACKGROUND There has been a transition to using patient-reported outcome instruments ( PROi ) to assess surgical effectiveness . However , none of these instruments have been vali date d for outcomes of adult Chiari I malformation ( CMI ) . OBJECTIVE The aim of this study was to determine the relative validity and responsiveness of various PROi in measuring outcomes after surgery for CMI . METHODS Fifty patients undergoing suboccipital craniotomy for adult CMI were prospect ively followed for 1 year . Baseline and 1-year patient-reported outcomes ( visual analog scale for head pain and visual analog scale for neck pain , Neck Disability Index [ NDI ] , Headache Disability Index , SF-12 , Zung Self-Rating Depression Scale , and EuroQol-5D [ EQ-5D ] ) were assessed . A level of improvement in general health after surgery was defined as meaningful improvement . Receiver-operating characteristic curves were generated to assess the validity of PROi to discriminate between meaningful improvement and not . The difference between st and ardized response means ( SRMs ) in patients reporting meaningful improvement vs not as calculated to determine the relative responsiveness of each outcome instrument . RESULTS For pain and disability , the NDI was the most accurate discriminator of meaningful effectiveness ( area under the curve : 0.90 ) and also most responsive to postoperative improvement ( st and ardized response means difference : 1.87 ) . For general health and quality of life , the SF-12 PCS , EQ-5D , and Zung Self-Rating Depression Scale were all accurate discriminators ; however , SF-12 Physical Component Scale ( SF-12 PCS ) and EQ-5D were most accurate . SF-12 PCS was also most responsive . CONCLUSION For pain and disability , NDI is the most valid and responsive measure of improvement after surgery for CMI . For health-related quality of life , SF-12 PCS and EQ-5D are the most valid and responsive measures . NDI with SF-12 or EQ-5D is the most valid in patients with CMI and should be considered in cost-effectiveness studies Background : This study is a trial to compare the effects and outcomes of three different  bariatric procedures performed in two centers .  St and ard Roux-en-Y gastric bypass was performed by Dr. Norman Samuels in Fort Lauderdale ( Florida ) ; vertical b and ed gastroplasty and laparoscopic adjustable silicone gastric b and ing were done in Hallein ( Salzburg ) by Dr. Emanuel Hell and Dr. Karl Miller . Methods : In a prospect i ve comparative study 30 matched patients from each group were followed to assess post-operative improvement in health status and quality of life , to compare the three different techniques . The  Bariatric Analysis and Reporting Outcome System ( BAROS  ) as described by Oria and Moorehead has been used for evaluation . Results : The observation time was at least 3 years ( 3 to 8 years ) in each individual case . A significant increase in quality of life and health status in 75 % of the surgically-treated patients was observed when compared with a non-operated control group of morbidly obese patients . Conclusions : By utilizing BAROS it has been found possible to compare the results of different procedures done by different surgeons with different techniques , utilizing patients from different cultures and with different language s. The results of this comparative study favor the st and ard gastric bypass for the treatment of morbid obesity . This operation is superior to purely gastric restrictive procedures in weight loss and improvement of quality of life 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 r and omised 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 implication s for the NHS and other healthcare providers as improved effectiveness of bariatric surgery reduces the health costs of obese patients in the longer term . Trial registration Clinical Trials.gov NCT01264120 Background : The Netherl and s has a population of 20,000 morbidly obese patients , an average of 350 of whom per year undergo a stomach reduction operation  involving the surgical placement of a Lap-B and ® . The quality of life ( QOL ) of a sample of female patients who underwent this operation was studied in a 1-year postoperative study . Methods : The Medical Outcome Study Short Form-36 ( MOS SF-36 ) was used to assess 1-year postoperative quality of life among a sample of 39 female patients aged 19 - 53 years .  QOL was measured at most 20 h preoperatively and 1 year postoperatively using a r and omized pretest/posttest design . Statistical data , after transformation , were analyzed with SPSS Version 7.5 for Windows 95 . Results : The response rate of 92.9 % of patients polled was good , in contrast to earlier findings with this measuring instrument . Mean body mass index ( BMI ) declined from 40.86 kg/m2 preoperatively to 33.14 kg/m2 1 year postoperatively . QOL improved on all scores in the MOS SF-36 . Internal consistency of the scales used was high . Conclusions : The response rate to the MOS SF-36 question naire was high . The surgical placement of a Lap-B and ® result ed in a significant improvement of QOL ( 1 year postoperatively ) on all scores used . The internal consistency of the scales used was high
Conclusions The BODY-Q provides a set of independently functioning scales that measure issues important to patients who undergo weight loss .
BODY-Q scales were responsive to measuring clinical change associated with weight loss 2 years after bariatric surgery
Background Recent systematic review s have identified that current patient-reported outcome instruments have content limitations when used to measure change following bariatric surgery .
The aim of this study was to measure change after bariatric surgery using the BODY-Q , a PRO instrument design ed for weight loss and body contouring .
