Objectives/hypothesis: To evaluate trends, outcomes, and healthcare utilization following medialization laryngoplasty (ML) with or without arytenoid adduction (AA) over 10 years.
Study design: Retrospective observational study.
Methods: Using OptumLabs Data Warehouse, trends, outcomes, and healthcare utilization from 2006 to 2015 were examined with a focus on discharge type (same day or not). Predictors of postoperative emergency department (ED) use and hospitalization were determined by multivariable logistic regression.
Results: Overall rate of ML was 1.09 per 100 thousand enrollees per year. Of these, 7.8% ML were combined with an AA. Outpatient same-day discharge represented 62.0% (1,142 of 1,843) of total patients, steadily increasing over the 10-year period (P < 0.01). There was a 5.9% revision ML rate and 1.0% rate of tracheotomy within 1 day of ML. A total of 5.6% visited an ED, and 5.4% were admitted to a hospital following initial discharge within 30 days. Same-day discharge was found to be a predictor of hospitalization within 30 days after ML (odds ratio [OR] 1.74, P = 0.0452), along with Elixhauser comorbidity index of 4 + (OR 5.74, P = 0.0001). Pulmonary embolism, pulmonary hypertension, and weight loss were top predictors of ED visit or hospitalization.
Conclusion: To our knowledge, this is the first search evaluating national claims data for ML with or without AA. Overall rate of ML is low, and same-day discharge has become more common over a 10-year period, with an associated higher 30-day hospital admission risk. Correct patient selection criteria for disposition status cannot be fully determined based on current data, but a high Elixhauser comorbidity index clearly carries increased risk for hospitalization after initial discharge.
