Preoperative Functional Status Is Associated With Unplanned Intubations Following Thyroidectomies

Area of Science:

• Surgery
• Anesthesiology
• Patient Outcomes

Background:

• Unplanned postoperative intubation is a significant complication impacting outcomes in thyroid and parathyroidectomies.
• Preoperative functional status is a critical factor to consider in surgical risk assessment.

Purpose of the Study:

• To investigate the association between preoperative functional status and unplanned intubation after thyroid and parathyroid surgery.
• To compare intubation outcomes between functionally independent and dependent patients undergoing these procedures.

Main Methods:

• Retrospective cohort study using the National Surgical Quality Improvement Program (NSQIP) database (2007-2013).
• Propensity score matching was employed to create comparable groups of functionally independent and dependent patients.
• Kaplan-Meier survival analysis and Cox proportional hazards modeling were used to assess outcomes.

Main Results:

• A total of 98,035 thyroid and parathyroidectomies were analyzed.
• The functionally dependent group had a significantly higher rate of unplanned intubation within 30 days post-surgery (33 vs. 11 per 1,000 persons, P < .001).
• Dependent functional status was independently associated with a 2.4-fold increased risk of unplanned intubation (HR 2.4, 95% CI 1.4-4.18, P = .002).

Conclusions:

• Preoperative functional status is a valuable predictor of re-intubation risk following thyroid and parathyroidectomy.
• Identifying functionally dependent patients preoperatively can aid in risk stratification and management strategies.
• Early postoperative outcomes (days 0-1) did not differ significantly between groups, suggesting delayed respiratory complications in dependent patients.
