Evaluating resident involvement and the 'July effect' in parotidectomy

Area of Science:

• Surgical Outcomes Research
• Head and Neck Surgery
• Medical Education

Background:

• The 'July effect' describes potential increased risks during academic year transitions.
• Evaluating resident involvement in parotidectomy is crucial for patient safety and training.
• Parotidectomy is a complex head and neck surgical procedure.

Purpose of the Study:

• To assess the impact of resident participation on peri-operative complications after parotidectomy.
• To investigate whether the 'July effect' influences outcomes in parotidectomy cases involving residents.

Main Methods:

• Analysis of the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database.
• Inclusion of parotidectomy procedures with resident involvement from 2005 to 2014.
• Statistical comparison of outcomes between cases with and without resident participation, and across academic quarters.

Main Results:

• A total of 11,733 parotidectomy cases were analyzed, with 7.9% involving residents.
• Resident involvement was linked to significantly lower reoperation (aOR 0.18) and readmission rates (aOR 0.30).
• Cases with residents had longer operative times (mean 24 min increase) and hospital stays (23.5% increase), but no difference in complication or mortality rates, nor an effect of the 'July effect'.

Conclusions:

• Resident participation in parotidectomy is associated with improved safety outcomes, specifically reduced reoperation and readmission rates.
• Despite longer operative times and hospital stays, resident involvement does not increase overall complication rates.
• The 'July effect' does not appear to pose an increased risk for adverse peri-operative outcomes in parotidectomy procedures.
