MethodsThe California Office of Statewide Health Planning and Development database was retrospectively analyzed from 1995-2010. Main outcome measures were complications including death. Logistic regression identified risk factors for complications.
ResultsThere were 106,773 patients. 61% were female and 44% Caucasian. 16,287 (15%) thyroidectomies were performed at high volume centers. Complication rates included voice change (0.5%), vocal cord dysfunction (1.1%), hypocalcemia (4.5%), tracheostomy (1.62%), hematoma (1.75%), and death (0.3%).
There was significantly increased risk of complications for patients older than 65 compared to younger than 40. High volume hospitals were protective against complication.
