Hawkins Foundation - 3 Shoulder Instability - Labral Reconstruction: Change in Validated Shoulder Patient Reported Outcome Measure Following Labral Reconstruction for Shoulder
The change in a validated shoulder measure score will be used as a performance measure for surgeons performing labral reconstruction for shoulder instability. Two measures will be created and reported by each surgeon. Surgeons will report the average shoulder measure change score for patients treated during the observation period. In addition, surgeons will produce a risk-adjusted shoulder measure change score ratio by dividing the average patient shoulder measure change score by the average predicted patient shoulder measure change score calculated using the formula provided. These measures will serve as sports medicine performance measures at the eligible surgeon level.
Eligible validated shoulder patient reported outcome measures include: American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), Western Ontario Shoulder Instability Index, Single Assessment Numeric Evaluation (SANE)
Defining the population:
CPT-4 codes will be used to identify patients who received labral repair or reconstruction for shoulder instability.
Labral repair or reconstruction for shoulder instability during the reporting period CPT-4 Codes: 29806, 29807, 23450, 23455, 23460, 23462, 23465, 23466, 23462, 29806, 23455, 23466, 23662, excluding revisions (23450 and 23460).
Surgeons who performed a minimum of 25 labral repair or reconstruction procedures a year will be eligible to submit this measure.
Time-period for data collection and reporting:
This measure will be calculated using all patients who underwent surgery for shoulder instability during the observation period. Patients receiving surgery for shoulder instability during the period 18 to 6 months prior to the reporting data will be included in the analysis to ensure 6 months of patient-reported follow-up in the shoulder measure score are available.
Two surgeon-level performance measures will be reported. The unadjusted measure will be the average 6-month shoulder measure change score across all shoulder instability patients treated by the surgeon. The adjusted measure will be the ratio of the average shoulder measure change score divided by the average predicted shoulder measure change score for all patients treated by the surgeon.
Unadjusted measure: Average Shoulder Measure Change Score
NUMERATOR: Average 6-month shoulder measure change score for all shoulder instability patients treated by surgeon.
DENOMINATOR: Average predicted 6-month shoulder measure change score for all shoulder instability patients treated by surgeon.
Risk adjustment methods and variables:
The predicted 6-month shoulder measure change scores are estimated for each patient using the Center for Effectiveness Research in Orthopaedics’(CERortho) risk adjustment regression model that includes the following patient variables: age, gender, BMI, smoking status, sport participation/activity level, comorbidities, worker’s compensation status, type of instability, labral tear location, labral tear size, bone loss, concomitant injuries (acromioclavicular, rotator cuff tear, fracture) the baseline shoulder measure, and baseline measures of pain, shoulder function, and quality of life.
Variables included in the current CERortho risk model are based on information in available databases. CERortho plans to constantly update these specified variables based on input from evaluated surgeons and specialty organizations. Appendix A contains the list of baseline concepts from peer-reviewed literature that are thought to affect outcomes of treatment and will be candidates for future inclusion in the model.
