Bariatric Surgical QualityOld Paradigm was a very good start……..now it is time to evolve
![Page 3: Assessing Performance: New Strategies Robin Blackstone, MD, FACS, FASMBS President, ASMBS MISS 7:30am Saturday February 25.](https://reader036.fdocuments.in/reader036/viewer/2022070410/56649ef15503460f94c02d3d/html5/thumbnails/3.jpg)
On February 6, 2012 the ASMBS Executive Council agreed to merge the BSCOE program with the American College of Surgeons(ACS) BCSN program.On February 10, the ACS Board of Regents agreed.
821 programs will merge April 1, 2012 based on the current volume standards.

Foundation of New Program
All current programs in either BCSN or BSCOE will be accredited in the new program under the current volume based standards
Content and Direction of the program will be through committees that are being established out of the current ASMBS and ACS bariatric committees
Joint (ACS/ASMBS/SAGES) Credentialing Recommendations will be made
A new outcomes based standard will evolve to replace the current volume based standards
The program will have a joint data registry
Robust Bariatric Quality Improvement on a National/Regional and State wide basis will be put in place

Database launched in 2007; Entry of data into BOLD became a requirement for BSCOE designation in early 2008 Surgeons/surgical practices responsible for data entry
Source of initial data elements and definitions: Research Advisory Committee (RAC), Bariatric Surgery Review Committee (BSRC), SRC Research Department Staff Sought compatibility with NIH LABS data collection
Primary purpose was to monitor compliance with BSCOE requirements; Secondary purpose was for research Compliance monitoring focused only on surgical volume and
30-day serious complications (deaths, transfers, readmissions, revisions and reoperations)
Many questions asked in the database were intended for research
History of BOLDResearch Director SRC: Debbie Winegar

11
Initial IRB situation complex Informed consent required for all patients
IRB oversight required for all: Sites had option to waive oversight to central IRB or retain local IRB oversight
IRB situation simplified in 2010 with move to Copernicus Group IRB
Waiver of documentation of informed consent
Oversight of sites not required by central IRB
No specific qualifications required for data entry personnel Each program determined the appropriate skill set of
individual(s) who would enter their data
In 2010, requirement added that a BOLD Administrator be named for each practice

BSCOE participants questioned the value of data collection relative to the burden
BOLD reports not widely utilized
Felt that too many questions were research-orientedo Patient information/demographics – 13-19 questionso Preoperative visit – 38 questions o Hospital visit – 24 questionso Postoperative visit – 36 questions
A review of BOLD data elements launched in 2010 Surgeon experts proposed a significant reduction in the
number of core data elements Plan approved by BSRC and EC in 4Q2010 Improvements not executed

13
Data self-reported by programs Potential for bias when data entered by key program personnel
with vested interest in outcomes
Heterogeneity of data entry personnel No specific qualifications (e.g., health/science background) have
been required for data entry personnel; each program has selected whomever they feel can fulfill the role
While this policy accommodates all types of program structures, it can lead to variations in data entry practices that can affect data quality
Inadequate training of data entry personnel and lack of data entry support materials Although basic data entry training has been accessible, neither a
software manual nor guidelines on how to enter specific cases have been provided to data entry personnel
Inadequate training allows room for self-interpretation of data definitions and leads to variations in data entry practices
Limitations of the Database
![Page 14: Assessing Performance: New Strategies Robin Blackstone, MD, FACS, FASMBS President, ASMBS MISS 7:30am Saturday February 25.](https://reader036.fdocuments.in/reader036/viewer/2022070410/56649ef15503460f94c02d3d/html5/thumbnails/14.jpg)
14
Non-standard data definitions The use of non-standard data definitions in BOLD (e.g., comorbidity
severity scale; certain complications) limits its utility for making comparisons with or for combining with data from with other registries
Lack of sensitivity of the comorbidity severity scale The severity scale captures improvement in many comorbidities
only when there is a major change in treatment regime (e.g., whether medications are required) unlike changes in standard measures (e.g., HbA1c)
Leads to potential underestimation of comorbidity resolution
Potential under-representation of complications Surgical programs have been responsible for entering all
complications in BOLD, even those managed by other health care providers
The likelihood is high that bariatric programs may not be aware of all events that have occurred thus, complications in BOLD are potentially under-represented
Limitations of the Database - 2
![Page 15: Assessing Performance: New Strategies Robin Blackstone, MD, FACS, FASMBS President, ASMBS MISS 7:30am Saturday February 25.](https://reader036.fdocuments.in/reader036/viewer/2022070410/56649ef15503460f94c02d3d/html5/thumbnails/15.jpg)
15
Variations in the time to data entry There has never been a required time frame with which data must be
entered into BOLD following a patient visit
Leads to the appearance of missing follow-up data at a given point in time
Frequency of on-site data auditing The current schedule for on-site data auditing (every three years as
part of site inspection) may not be sufficient to detect program-specific issues and to keep programs honest
Thoroughness of data auditing BOLD data auditing has been limited to surgeries performed during a
one-year period preceding the site inspection and has been focused on a subset of data elements: procedures, complications, readmission, reoperations and transfers
In general, ~10% of cases selected for random chart review
A 100% chart review triggered by unreported events
Limitations of the Database - 3
![Page 16: Assessing Performance: New Strategies Robin Blackstone, MD, FACS, FASMBS President, ASMBS MISS 7:30am Saturday February 25.](https://reader036.fdocuments.in/reader036/viewer/2022070410/56649ef15503460f94c02d3d/html5/thumbnails/16.jpg)
16
Inconsistent follow-up intervals among programs Necessitates the use of wide visit windows for the assessment of
outcomes
Incomplete follow-up data Lack of a follow-up tracking report in BOLD has been an
inconvenience for programs however incomplete follow-up is a common problem faced by all bariatric databases
Inadequate feedback to programs through BOLD reports- The BOLD reports provided to date have not shown a program’s
risk-adjusted outcomes vs national risk-adjusted benchmarks nor have they presented all program data in a useful format (e.g., comorbidity data)
- The usefulness of BOLD data for quality improvement has been limited
Limitations of the Database - 4
![Page 17: Assessing Performance: New Strategies Robin Blackstone, MD, FACS, FASMBS President, ASMBS MISS 7:30am Saturday February 25.](https://reader036.fdocuments.in/reader036/viewer/2022070410/56649ef15503460f94c02d3d/html5/thumbnails/17.jpg)
Potential settlement agreement will provide the data through March 31, 2012 to ASMBS for all programs (unless you specifically opt out)
All programs will receive a risk adjusted and reliability adjusted composite measure and comprehensive data report for each surgeon and program participating on June 22, 2012 at the annual meeting during the first Annual National Bariatric Quality Forum from 10am - 12 noon. All programs should make sure the bariatric coordinator and medical director of the program are there to participate in that meeting.
The data will not be migrated due to the limitations as noted in the previous slides
What will happen to the BOLD data in the transition
![Page 18: Assessing Performance: New Strategies Robin Blackstone, MD, FACS, FASMBS President, ASMBS MISS 7:30am Saturday February 25.](https://reader036.fdocuments.in/reader036/viewer/2022070410/56649ef15503460f94c02d3d/html5/thumbnails/18.jpg)

BOLD Data Dissemination Committees through Research Committee
Data Access Committee (DAC) reviewed requests for BOLD data
Through Sept 2011, 106 requests for data received, 30% for research, 17% for quality improvement
The majority of requests (58%) were received from BSCOE participants
Data Dissemination Committee (DDC) reviewed requests for publication of information derived from BOLD data analysis
Through Sept 2011, 20 abstracts/presentations and 6 manuscripts containing BOLD data were reviewed by the DDC
BOLD data provided for payor negotiations; Data on sleeve provided to CMS for NCD consideration
Dissemination of BOLD Data

Programs genuinely want to do the right thing in terms of data collection but they need clear information on what is expected
Data collection is expensive for everyone but is essential for quality assessment and improvement
Have a clear plan as to what the purpose of the data collection is and communicate that to program participants
Tie data collection to accreditation to emphasize its importance
Less is more - focus on fewer data points and do a better job with them
Proper training of data entry personnel is critical for obtaining high quality data
Feedback of information to programs demonstrates the value of the data collection effort and keeps them engaged
Lessons Learned

Volume and relationship to mortality
The mortality of bariatric surgery has declined dramatically from 2004 (o.2%) to 2009 (0.1%)
The primary driver of the decline was the wide spread adoption of laparoscopic surgery from 2004 (29.9%) to 2008 (90.2%)
The second biggest driver was the inclusion of a very low risk procedure (Adjustable Gastric Band) 2004 (1%) vs. 2008 (29%)
Not clear how much additional decrease in mortality was due to volume based accreditation
Failure to rescue patients may be of critical importance – emphasizing the importance of collaborative networks of care
Because of the current accreditation stands ASMBS does not have data on programs doing les than 125 cases per year (ACS data seems to indicate that down to 25 cases a year the outcomes are very similar, in a risk adjusted environment. Nguyen, J Am Coll Surg 2011;213:261–266
![Page 23: Assessing Performance: New Strategies Robin Blackstone, MD, FACS, FASMBS President, ASMBS MISS 7:30am Saturday February 25.](https://reader036.fdocuments.in/reader036/viewer/2022070410/56649ef15503460f94c02d3d/html5/thumbnails/23.jpg)
Lessons from LABS
Historic surgeon experience was not related to adverse event rate
After adjusting for patient risk, the effect of surgeon volume on outcomes for RYGP procedures in LABS showed that for each increase by 10-case per year in surgeon volume the rate of composite events improved by 10 percent.
The observed relationship between surgeon RYBP volume and CE rates was continuous, illustrating that there was no satisfactory level of annual case volume that could act as a threshold for surgeon credentialing within the BSCOE
No significant differences were observed in mortality between low and high volume surgeons.

The Role of Risk Adjustment
Important because surgeons feel that if their outcomes are poor it is because they are operating on sicker patients
Challenges in Risk adjustment there is no one factor that has emerged to adjust risk Risk adjustment has changed with time and the data set The most significant predictor of risk in any report has
been the procedure itself The adverse event curve is “J” shaped In order to use data to do risk adjustment the data
definitions have to be crystal clear and the number of patients in follow up has to be high – pulmonary hypertension example
![Page 25: Assessing Performance: New Strategies Robin Blackstone, MD, FACS, FASMBS President, ASMBS MISS 7:30am Saturday February 25.](https://reader036.fdocuments.in/reader036/viewer/2022070410/56649ef15503460f94c02d3d/html5/thumbnails/25.jpg)

Reliability AdjustmentWhen data is unreliable
![Page 27: Assessing Performance: New Strategies Robin Blackstone, MD, FACS, FASMBS President, ASMBS MISS 7:30am Saturday February 25.](https://reader036.fdocuments.in/reader036/viewer/2022070410/56649ef15503460f94c02d3d/html5/thumbnails/27.jpg)
The “Shrinkage” Debate
• In traditional statistics, the observed rate is thought to best represent the truth (n outcomes/k trials)
• Bayesian statistics considers observed data in the context of prior information
• Empirical Bayes derives prior information from the data– e.g., the “best” guess is a rate
somewhere between the observed rate and the overall rate
• Accomplished using hierarchical modeling

Volume still counts
Only counts as much as the data dictates it should
With the new program we will get data from the first case
If Volume is found to matter it can be added back based on the data
Key components: Data/structure and process set up at beginning Somewhere between 25-40 cases you will be able to
generate a composite outcomes score

Collaborative quality improvement
Basic idea: Physicians/hospitals collaborate with and learn from each other in improving outcomes
Robust data registry with “digital” capability
Empirical and non-empirical identification of best practices Leveraging “natural experiments” associated with variation in
practice across hospitals and physicians Non-empirical learning
Performance feedback, collaborative meetings, site visits, etc.
Empirical identification and dissemination of best practices Process-outcomes linkage, leveraging “natural experiments” associated
with variation in practice Guideline implementation and evaluation
