Abstract
BACKGROUND: The rising proportion of older adults in the US population coupled with an increased prevalence of nodular thyroid disease will result in more thyroidectomies being performed. The aim of this study is to evaluate the clinical outcomes among older adults (age ≥65) undergoing thyroidectomy compared to younger adults (18-64). METHODS: This was a population-based study of adult thyroidectomy patients using the Premier Healthcare Database, 2005-2014. Discharge status, hospital length of stay (LOS), morbidity, and total patient charge were compared between younger adults and older adults in three different age groups: ≥65, ≥70, and ≥80 years old. RESULTS: Among 75,141 thyroidectomy patients, 15,805 (21.0%) patients were ≥65 years, 8834 (11.8%) were ≥70 years, and 1613 (2.2%) were ≥80 years. Patients ≥80 years were 2.6 times (aOR:2.58, 95%CI: 1.72-3.86; p < 0.001) more likely to be discharged to a home health organization than to be discharged to their residence and 1.6 times (aOR:1.61, 95%CI: 1.30-2.00; p < 0.001) more likely to have at least one complication. CONCLUSIONS: Age ≥80 is an independent predictor of worse clinical outcomes after thyroidectomy.
