Postoperative Complications After Thyroidectomy: Time Course and Incidence Before Discharge

Area of Science:

• Surgical Outcomes Research
• Thyroid Surgery
• Patient Safety

Background:

• Thyroidectomy complication rates are known, but their timing is less understood.
• Early adverse events significantly impact patient recovery and healthcare resource utilization.
• Establishing a clear timeline for thyroidectomy complications is crucial for improving patient care.

Purpose of the Study:

• To delineate the timeline of early adverse events following thyroidectomy.
• To identify risk factors associated with these early complications.
• To analyze complication timing based on thyroidectomy extent (hemithyroidectomy vs. total thyroidectomy).

Main Methods:

• Retrospective review of 161,534 thyroidectomy patients (2005-2018).
• Utilized the American College of Surgeons National Surgical Quality Improvement Program database.
• Analyzed time to specific complications and used multivariate logistic regression for risk factor identification.

Main Results:

• Overall complication rate was 3.28%, with most occurring before discharge (e.g., blood transfusion, hematoma, pneumonia, cardiac arrest).
• Mortality and some severe complications like pulmonary embolism occurred more frequently after discharge.
• Outpatient thyroidectomy was linked to a reduced risk of 7-day postoperative complications (OR 0.41).

Conclusions:

• Early complications after thyroidectomy, while rare, follow a distinct temporal pattern, with many manifesting post-discharge.
• Understanding this timing is essential for optimizing preoperative patient and provider communication.
• Selected patients undergoing outpatient thyroidectomy demonstrate a lower overall risk of early complications.
