The cost-effectiveness of laparoscopic adjustable gastric banding in the morbidly obese adult population of Australia.

ABSTRACT:

Background

To examine the cost-effectiveness of providing laparoscopic adjustable gastric banding (LAGB) surgery to all morbidly obese adults in the 2003 Australian population.

Methods and findings

Analyzed costs and benefits associated with two intervention scenarios, one providing LAGB surgery to individuals with BMI >40 and another to individuals with BMI >35, with each compared relative to a 'do nothing' scenario. A multi-state, multiple cohort Markov model was used to determine the cost-effectiveness of LAGB surgery over the lifetime of each cohort. All costs and health outcomes were assessed from an Australian health sector perspective and were discounted using a 3% annual rate. Uncertainty and sensitivity analyzes were conducted to test the robustness of model outcomes. Incremental cost-effectiveness ratios (ICERs) were measured in 2003 Australian dollars per disability adjusted life year (DALY) averted. The ICER for the scenario providing LAGB surgery to all individuals with a BMI >40 was dominant [95% CI: dominant -$588] meaning that the intervention led to both improved health and cost savings. The ICER when providing surgery to those with a BMI >35 was $2,154/DALY averted [95% CI: dominant -$6,033]. Results were highly sensitive to changes in the likelihood of long-term complications.

Conclusion

LAGB surgery is highly cost-effective when compared to the $50,000/DALY threshold for cost-effectiveness used in Australia. LAGB surgery also ranks highly in terms of cost-effectiveness when compared to other population-level interventions for weight loss in Australia. The results of this study are in line with other economic evaluations on LAGB surgery. This study recommends that the Australian federal government provide a full subsidy for LAGB surgery to morbidly obese Australians with a BMI >40.

Project description:Elevated rates of psychopathology are noted among severely obese youth presenting for weight loss surgery. The role of mental health providers in this population is not well defined, and the selection of candidates is often the result of clinical judgment alone. The purpose of this study was to comprehensively evaluate psychiatric symptoms among a large sample of adolescents receiving laparoscopic adjustable gastric banding (LAGB) by (1) examining changes in depressive symptoms and quality of life in the year following surgery; (2) evaluating the interaction between patterns of change in depression, quality of life, and weight postsurgery; and (3) identifying presurgical psychological predictors of initial weight change.Participants were 101 severely obese adolescents aged 14 to 18 years receiving LAGB at the Center for Adolescent Bariatric Surgery at the Morgan Stanley Children's Hospital of New York Presbyterian/Columbia University Medical Center between August 2006 and December 2009. Measures of height, weight, depressive symptoms, and quality of life were obtained in the first year following surgery. Changes in the Beck Depression Inventory (BDI), Pediatric Quality of Life Inventory (PedsQL), and body mass index were analyzed using latent growth curve modeling.Short-term changes in psychiatric symptoms and weight were analyzed using latent growth curve modeling. Significant changes in total BDI (?slope = -0.885, SE = 0.279, P < .01; ?quadratic = 0.054, SE = 0.021, P < .001) and PedsQL (?slope = -0.885, SE = 0.279, P < .001) scores were observed following LAGB, and comparable postoperative changes between psychosocial variables and body mass index were also noted (BDI: covariance [COV] = 0.21, SE = 0.06, P < .001; PedsQL: COV = -0.41, SE = 0.10, P < .01). Two variables (family conflict/loss of control eating) were found to be significant predictors of weight change over the year following surgery (P < .05).Adolescents experienced notable improvements in initial depressive symptoms and quality of life after LAGB, and measures of preoperative binge eating and family conflict affected postsurgery body mass index among youth.ClinicalTrials.gov identifier: NCT01045499.

Project description:IMPORTANCE:There is conflicting evidence about how different bariatric procedures impact health care use. OBJECTIVE:To compare the impact of laparoscopic adjustable gastric banding (AGB) and laparoscopic Roux-en-Y gastric bypass (RYGB) on health care use and costs. DESIGN, SETTING, AND PARTICIPANTS:Retrospective interrupted time series with comparison series study using a national claims data set. The data analysis was initiated in September 2011 and completed in January 2015. We identified bariatric surgery patients aged 18 to 64 years who underwent a first AGB or RYGB between 2005 and 2011. We propensity score matched 4935 AGB to 4935 RYGB patients according to baseline age group, sex, race/ethnicity, socioeconomic variables, comorbidities, year of procedure and baseline costs, emergency department (ED) visits, and hospital days. Median postoperative follow-up time was 2.5 years. MAIN OUTCOMES AND MEASURES:Quarterly and yearly total health care costs, ED visits, hospital days, and prescription drug costs. We used segmented regression to compare pre-to-post changes in level and trend of these measures in the AGB vs the RYGB groups and difference-in-differences analysis to estimate the magnitude of difference by year. RESULTS:Both AGB and RYGB were associated with downward trends in costs; however, by year 3, AGB patients had total annual costs that were 16% higher than RYGB patients (P?<?.001; absolute change: $818; 95% CI, $278 to $1357). In postoperative years 1 and 2, AGB was associated with 27% to 29% fewer ED visits than RYGB (P?<?.001; absolute changes: -0.6; 95% CI, -0.9 to -0.4 and -0.4; 95% CI, -0.6 to -0.1 visits/person, respectively); however, by year 3, there were no detectable differences. Postoperative annual hospital days were not significantly different between the groups. Although both procedures lowered prescription costs, annual postoperative prescription costs were 17% to 32% higher for AGB patients than RYGB patients (P?<?.001). CONCLUSIONS AND RELEVANCE:Both laparoscopic AGB and RYGB were associated with flattened total health care cost trajectories but RYGB patients experienced lower total and prescription costs by 3 years postsurgery. On the other hand, RYGB was associated with increased ED visits in the 2 years after surgery. Clinicians and policymakers should weigh such differences in use and costs when making recommendations or shaping regulatory guidance about these procedures.
