Bariatric Surgery for the Treatment of Obesity and Obesity Related Complications

• Bariatric surgery is usually performed on

patients with a BMI ≥40 or ≥35 if they have obesity related complications such as diabetes, etc. 1

• 9.7% of US Adult women and 5.6% of

men in the United States have a BMI of 40 or above.2

• According to the American Society for

Metabolic and Bariatric Surgery (ASMBS), 228,000 bariatric surgery procedures were performed in 2017.1

• 1. The American Society for Metabolic and Bariatric Surgery (ASMBS) 2. National Center for Health Statistics

5

Why Do People Seek Bariatric Surgery?

• Primary reason is to improve health (controlling of medical

problems); but people also desire to improve quality of life, mental health, and appearance.1,2

• Family history of obesity and its related complications also plays

a big role. 3

• Utilization remains low with less than 1% of eligible recipients

seeking surgery. 4

Barriers to Surgery

• Obesity de-prioritized by healthcare providers.
• Obesity not recognized as a disease by some providers.
• Provider deferring to patient to suggest treatment agenda or initiate

referral.

• High societal stigma around obesity and seeking help for one’s
• besity.
• Belief that lifestyle change is most effective method to treat obesity.
• Lack of Insurance coverage (procedures excluded) and/or difficult

pre-authorization requirements.

• Fear of surgery

Replace Hype with Patient Centered Evidence

• PCORnet Bariatric Study compared the benefits and harms of the 3

most common types of weight loss surgery (Gastric Bypass, Sleeve Gastrectomy and Adjustable Gastric Band).

• Evaluated 65,000 patients who have had bariatric surgery at 41

healthcare systems across the US.

• While data was primarily available on adults, more than 700 of these

patients were adolescents from 12 – 19 years of age.

• Compared each type of weight loss surgery at 1, 3, and 5 years to see:
• How much weight people lost and regained over time.
• What happened to people with diabetes – remission, relapse, control.
• How often people had major complications – reoperation, hospitalization

The need for shared decision making (SDM)

• No one bariatric procedure is “right” for all patients.
• Patients and their physicians need to consider the complex trade
• ffs between the risks and the benefits of each procedure:
• Gastric bypass has the best weight loss and diabetes outcomes
• Sleeve gastrectomy has the lowest rate of reoperation and

hospitalization

• Adjustable banding has lowest early risk, but highest long-term risk
• Patients and providers need help with these conversations.

13

Goals of new project

• Incorporate PCORI comparative effectiveness evidence from the PCORnet

Bariatric Study into an existing bariatric surgery decision aid

• Implement the updated strategy into two health care systems: Kaiser

Permanente Washington (KPWA) and UPMC in Pennsylvania.

• The SDM Approach will address two preference-sensitive decisions for

patients with severe obesity (defined as a body mass index or BMI ≥40 or a BMI ≥35 with obesity-associated health conditions):

1) Whether to undergo bariatric surgery, and 2) Which bariatric procedure to undergo

14

Decision Aid: Weight Loss Surgery: Is it Right for You?

• Developed in 2005-2006 in collaboration with Health Dialog and

the Informed Medical Decisions Foundation

• Using IPDAS standards; systematic review; focus groups &

interviews with patients and providers; updated biannually

• Tested in a randomized, controlled trial* including 152 patients
• ½ pre-op bariatric referrals; ½ general medical patients
• DA significantly increased patients’ knowledge of their health condition,

reduced their decisional conflict, and improved outcome expectancies

• Decision aid is being updated to include 5-year data from PBS

*Arterburn D, et al. Obesity, 2011

15

Existing SDM Infrastructure

• KPWA: began its large-scale SDM implementation effort in 2009*
• Has distributed more than 50,000 decision aids and trained more than 1000

providers in SDM within their system since that time.

• The prior KPWA SDM implementation work was not focused on bariatric

surgery, so this is an opportunity to expand our established SDM program.

• UPMC: relatively SDM-naïve environment (i.e., there have been no

formal efforts to implement a broad-scale SDM Approach at UPMC)

• We will test the ability to spread the KPWA SDM Approach into a traditional

fee-for-service health care environment (different from the KP model)

• Has a world-renowned bariatric surgical program (UPMC has one of the

largest and oldest bariatric programs in the United States)

16

What work was done at implementation sites to get them on board and help assure the success?

• At KPWA, we engaged SDM experts and quality leaders, and we

engaged primary care leaders and bariatric surgeons in design of the project; obtained letters of support and commitment of resources

• At UPMC, we engaged leaders in quality and IT, and we engaged

primary care leaders, and bariatric surgeons in design of the project; obtained letters of support and commitment of resources

The Six Steps of Shared Decision Making

• 1. Invite patient to participate
• 2. Present options
• 3. Provide information on risks and benefits
• 4. Elicit patient preferences
• 5. Facilitate deliberation and decision making
• 6. Assist patient with implementing decision

Implementation Strategies

Numbers Implementation Strategy Description of Implementation Strategy Barriers to SDM Addressed

1 Engage formally appointed leaders

Formally appointed leaders identified for KPWA and UPMC; co-developed implementation strategy with leadership input Poor leadership buy-in

2 Identify clinical champions for SDM

Clinical champions; bariatric and primary care; nominated by clinical leadership or self-nominated; Champions will be formally trained on SDM with a focus on bariatric surgery Lack of motivation for SDM

3 Form Implementation Resource Team

An IRT will be formed at each site (KPWA and UPMC) and will include representatives from relevant stakeholders; many members already identified Low system engagement

4 Train providers on SDM process and skills

Separate online CME programs for PCPS and surgeons; virtual; CME credit offered; Content: bariatric surgery evidence, SDM 6 steps, decision aid overview, tools for implementation, audit & feedback plan Understanding of SDM and bariatric surgery evidence

5 Mandated participation in SDM

IRT leadership communicate clear expectations to bariatric surgeons that SDM is mandatory; primary care leadership set expectation for use of SDM Approach in conversations about treatment options SDM not a priority clinically

6 Develop Workflow

Detailed SDM workflows are develop by IRT and adapted to the local clinical setting (e.g., likely different for surgical versus primary care) Unclear who is accountable for SDM happening

7 IT Support Tools

Epic ordering and messaging tools facilitate easy delivery of decision aids; we will automate decision aid delivery at referral to bariatric clinic; smart phrases will document SDM conversations Lack of time for SDM

8 Audit and Feedback

Public reports generated monthly track decision aid use, bariatric referral, and procedure volume, as well as SDM documentation with feedback to providers about performance Lack of explicit performance monitoring

9 Ongoing consultation

Follow-up meetings of IRT with care teams discuss DA use and SDM documentation; provide

• pportunity for feedback on public report; assess barriers, facilitators; check and adjust

Uneven SDM uptake across providers/staff

20

Evaluation Plan

• SDM Fidelity: Patient-reported outcomes captured with the

CollaboRATE, SDM-Q-9, and National Quality Forum SDM process measures

• 150 patients (75 per site); During Preparatory, Implementation,

Sustainment Phases; Primary Care and Bariatric Clinic

• Decision Aid Use & Sustainment
• Documentation of SDM in Medical Record
• # Bariatric Referrals; # Bariatric Procedures; Procedure type
• Provider Engagement with DA/SDM; Provider Satisfaction

21

Role of patients and/or other stakeholders

• Neely Williams, PBS Co-PI, serving on KPWA and UPMC

Implementation Resource Teams (IRT)

• New pre-operative bariatric patient on each IRT
• Surgeons and Primary Care Providers on IRT
• Meetings with bariatric and primary care teams
• Stakeholder Advisory Group: patients; surgeon leaders from the

American Society of Metabolic and Bariatric Surgeons; primary care clinicians, CEO of the Obesity Action Coalition (Nadglowski); policy lead from Association of American Medical Colleges; and a Medicare Coverage Advisory Committee member

22
