The study looked at 91 patients over an 11-month period, and found that the rate of complications were similar for outpatient or inpatient surgery, but the outpatient environment reduced costs by several thousand dollars.
For example, the average cost of outpatient surgery was $7,814, compared to $10,288 for an inpatient stay.
The study's authors noted that patients should should be carefully selected to include only those who prefer to recuperate at home, and that patients should be given calcium supplements to prevent calcium deficiencies that can arise after a thyroidectomy.
