Evaluation of Medicare's Intensive Behavioral Therapy for Obesity: the BieneStar Experience

Health insurance status, lifestyle choices and the presence of non-communicable diseases: a systematic review

BACKGROUND

Although health insurance (HI) has effectively mitigated healthcare financial burdens, its contribution to healthy lifestyle choices and the presence of non-communicable diseases (NCDs) is not well established. We aimed to systematically review the existing evidence on the effect of HI on healthy lifestyle choices and NCDs.

METHODS

A systematic review was conducted across PubMed, Medline, Embase, Cochrane Library and CINAHLComplet@EBSCOhost from inception until 30 September 2022, capturing studies that reported the effect of HI on healthy lifestyle and NCDs. A narrative synthesis of the studies was done. The review concluded both longitudinal and cross-sectional studies. A critical appraisal checklist for survey-based studies and the National Institutes of Health Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies were used for the quality assessment.

RESULT

Twenty-four studies met the inclusion criteria. HI was associated with the propensity to engage in physical activities (6/11 studies), consume healthy diets (4/7 studies), not to smoke (5/11 studies) or take alcohol (5/10 studies). Six (of nine) studies showed that HI coverage was associated with a lowered prevalence of NCDs.

CONCLUSION

This evidence suggests that HI is beneficial. More reports showed that it propitiated a healthy lifestyle and was associated with a reduced prevalence of NCDs.

A Survey of Primary Care Practices on Their Use of the Intensive Behavioral Therapy for Obese Medicare Patients

OBJECTIVE

To fill the gap in knowledge on systematic differences between primary care practices (PCP) that do or do not provide intensive behavioral therapy (IBT) for obese Medicare patients.

METHODS

A mixed modality survey (paper and online) of primary care practices obtained from a random sample of Medicare databases and a convenience sample of practice-based research network practices.

KEY RESULTS

A total of 287 practices responded to the survey, including 140 (7.4% response rate) from the random sample and 147 (response rate not estimable) from the convenience sample. We found differences between the IBT-using and non-using practices in practice ownership, patient populations, and participation in Accountable Care Organizations. The non-IBT-using practices, though not billing for IBT, did offer some other assistance with obesity for their patients. Among those who had billed for IBT, but stopped billing, the most commonly cited reason was billing difficulties. Many providers experienced denied claims due to billing complexities.

CONCLUSIONS

Although the Centers for Medicare and Medicaid Services established payment codes for PCPs to deliver IBT for obesity in 2011, very few providers submitted fee-for-service claims for these services after almost 10 years. A survey completed by both a random and convenience sample of practices using and not using IBT for obesity payment codes revealed that billing for these services was problematic, and many providers that began using the codes discontinued using them over the past 7 years.

Exposure to Weight Management Counseling Among Students at 8 U.S. Medical Schools

INTRODUCTION

Clinical guidelines support physician intervention consistent with the Ask, Advise, Assess, Assist, Arrange framework for adults who have obesity. However, weight management counseling curricula vary across medical schools. It is unknown how frequently students receive experiences in weight management counseling, such as instruction, observation, and direct experience.

METHODS

A cross-sectional survey, conducted in 2017, of 730 third-year medical students in 8 U.S. medical schools assessed the frequency of direct patient, observational, and instructional weight management counseling experiences that were reported as summed scores with a range of 0‒18. Analysis was completed in 2017.

RESULTS

Students reported the least experience with receiving instruction (6.5, SD=3.9), followed by direct patient experience (8.6, SD=4.8) and observational experiences (10.3, SD=5.0). During the preclinical years, 79% of students reported a total of ≤3 hours of combined weight management counseling instruction in the classroom, clinic, doctor's office, or hospital. The majority of the students (59%-76%) reported never receiving skills-based instruction for weight management counseling. Of the Ask, Advise, Assess, Assist, Arrange framework, scores were lowest for assisting the patient to achieve their agreed-upon goals (31%) and arranging follow-up contact (22%).

CONCLUSIONS

Overall exposure to weight management counseling was less than optimal. Medical school educators can work toward developing a more coordinated approach to weight management counseling.

Sharing the 'weight' of obesity management in primary care: integration of registered dietitian nutritionists to provide intensive behavioural therapy for obesity for Medicare patients

BACKGROUND

Clinical provision of intensive behavioral therapy for obesity (IBTO) has been a reimbursable treatment for obesity since 2012. However, gaps remain in the literature regarding its impact on patient outcomes.

OBJECTIVES

The primary objective of this study was to examine the integration of registered dietitian nutritionist provided IBTO into a primary care setting and evaluate clinic outcomes for Medicare Part B beneficiaries. A secondary objective was to examine intensity of IBTO (quantity of IBTO visits) versus clinical outcomes and influence of socioeconomic factors.

METHODS

A case-control retrospective chart review was conducted at a rural, Academic Family Medicine Clinic in Eastern North Carolina for patients seen between 1 January 2016 and 1 January 2019. In order to be included in the treatment group, patients had to be female, white or black race, have Medicare insurance and a body mass index ≥ 30 kg/m2.

RESULTS

Mixed model analysis showed statistically significant improvements in clinical outcomes from IBTO treatment. Weight decreased by nearly 3 pounds, while body mass index was half a point lower. A1C was 0.1 units lower for IBTO patients, and they took prescription medication and average of 6 days less than the control group. Minorities and older respondents experienced smaller, all else constant, and annual fixed effects suggest that differentials widen over time.

CONCLUSIONS

Registered dietitian nutritionist (RDN) provision of IBTO has demonstrated benefit in improving clinical outcomes including weight, A1C, and reduced medication duration (use) as demonstrated by the IBTO treatment group versus control. IBTO intensity was not predictive of success, and its impact was reduced with older and African American patients. IBTO is beneficial and can be delivered within the primary care setting by a RDN.

The association of obesity with health insurance coverage and demographic characteristics: a statewide cross-sectional study

We evaluated the statewide burden of obesity and its complications among government and state funded programs (Medicare and Medicaid) and commercial insurance.We calculated the prevalence of obesity and the prevalence of relevant comorbidities among different demographic groups and based on health insurance, among adults (18-65 years old) who visited a statewide health network in the state of Rhode Island, in 2017.The overall prevalence of obesity among 74,089 individuals was 38.88% [Asians 16.77%, Whites 37.49%, Hispanics 44.23%, and Blacks 48.44%]. Medicare or Medicaid beneficiaries were 26% and 27%, respectively, more likely to have obesity than those who had commercial insurance (Odds Ratio:1.26, 95% confidence interval [CI]:1.20-1.32; Odds Ratio:1.27, 95%CI:1.22-1.32). Moreover, Medicaid and Medicare beneficiaries with obesity had a higher prevalence of diabetes compared with privately insured with obesity (10.58% and 10.44% vs 4.45%). Medicare beneficiaries with obesity had a statistically higher prevalence of ischemic heart disease (4.34%, 95%CI: 3.77-4.91) than privately insured (3.21%, 95%CI: 2.94-3.47).Based on statewide data among 18 to 65 years old adults, Medicare and Medicaid provide health coverage to 40% of individuals with obesity and 46% of those with the obesity-related comorbidities and complications. State and federal health care programs need to support and expand obesity-related services and coverage.

Lifestyle intervention for obesity: a call to transform the clinical care delivery system in Mexico

Obesity and its comorbidities have become the most important public health problems for Latin America. In Mexico obesity has increased dramatically to the point where the government has declared it an epidemiological emergency. The most recent national data showed overweight and obesity affects 72.5% of adults, or around 56 million Mexicans. Most Mexican adults with obesity are undiagnosed. According to data derived from a national representative survey, only 20% of adults with BMI >30 kg/m² were diagnosed with obesity by a health provider. Likewise, only 8% of individuals with obesity had received treatment for obesity. Interventions offered in the Mexican health care delivery system generally consist of traditional consultations with recommendations on diet and exercise, visits are monthly to quarterly, and validated behavior change protocols are not used. Evidence from clinical trials has shown that weight loss with this type of treatment is generally less than 1 kg per year. In contrast, intensive lifestyle interventions - protocols focusing on achieving changes in diet, physical activity, and moderate weight loss using behavioral strategies with weekly or bi-weekly sessions for the first 3 to 6 months, and a maintenance phase with trained interventionists - as implemented in the Diabetes Prevention Program and the Look AHEAD studies achieved weight loss of 7-9% at one year. Additionally, translation studies of these interventions to the community and to real-world clinical practice have achieved weight loss of around 4%. Adaptations of intensive lifestyle interventions have been implemented in the United States, both in clinical practice and in the community, and this type of intervention represents a potential model to combat obesity in Mexico and other Latin American countries. It is essential that primary care providers in Mexico implement clinical practice guidelines based on the best evidence available as discussed here to effectively treat obesity. The authors make recommendations to improve the treatment of obesity in the clinical care delivery system in Mexico using intensive lifestyle interventions.

Intensive Behavioral Therapy for Obesity Combined with Liraglutide 3.0 mg: A Randomized Controlled Trial

OBJECTIVE

The Centers for Medicare and Medicaid Services (CMS) covers intensive behavioral therapy (IBT) for obesity. The efficacy, however, of the specific approach has never been evaluated in a randomized trial, as described here. The 1-year trial also assessed whether the addition to IBT of liraglutide 3.0 mg would significantly increase weight loss and whether the provision of meal replacements would add further benefit.

METHODS

A total of 150 adults with obesity were randomly assigned to: IBT (IBT-alone), providing 21 counseling visits; IBT combined with liraglutide (IBT-liraglutide); or IBT-liraglutide combined for 12 weeks with a 1,000- to 1,200-kcal/d meal-replacement diet (Multicomponent). All participants received weekly IBT visits in month 1, every-other-week visits in months 2 to 6, and monthly sessions thereafter.

RESULTS

Ninety-one percent of participants completed 1 year, at which time mean (± SEM) losses for IBT-alone, IBT-liraglutide, and Muticomponent participants were 6.1 ± 1.3%, 11.5 ± 1.3%, and 11.8 ± 1.3% of baseline weight, respectively. Fully 44.0%, 70.0%, and 74.0% of these participants lost ≥ 5% of weight, respectively. The liraglutide-treated groups were superior to IBT-alone on both outcomes. Weight loss in all three groups was associated with clinically meaningful improvements in cardiometabolic risk factors.

CONCLUSIONS

The findings demonstrate the efficacy of IBT for obesity and the potential benefit of adding pharmacotherapy to this approach.
