Association of Surrogate Objective Measures With Work Relative Value Units

Area of Science:

• Otolaryngology
• Health Services Research
• Medical Economics

Background:

• Accurate evaluation of surgeon work for reimbursement is challenging.
• Current systems for assigning work relative value units (RVUs) may not fully capture surgical complexity.
• Objective measures are needed to refine reimbursement accuracy.

Purpose of the Study:

• To determine the correlation between work RVUs and objective measures of surgeon work in otolaryngology.
• To identify objective predictors of work RVUs.
• To assess the potential for improving work RVU assignment accuracy.

Main Methods:

• Data from 2016-2018 American College of Surgeons National Surgical Quality Improvement Program otolaryngologic cases were analyzed.
• Pearson correlation coefficients assessed associations between work RVUs and objective measures (LOS, operative time, mortality, readmission, reoperation, morbidity).
• Multivariable linear regression identified predictors of work RVUs; studentized residuals identified outlying procedures.

Main Results:

• Work RVUs showed strong correlations with operative time (R=0.6775), 30-day readmission (R=0.6100), and length of stay (R=0.6083).
• Morbidity, reoperation, and operative time were the best predictors of work RVUs.
• Specific Current Procedural Terminology (CPT) codes demonstrated discrepancies between projected and current work RVU values.

Conclusions:

• Objective surrogate measures, including operative time and patient outcomes, can enhance the accuracy of work RVU assignment in head and neck surgery.
• Utilizing objective data may lead to a less subjective and more equitable reimbursement system.
• Further research incorporating additional objective parameters is recommended to refine work RVU assignments.
