Objective:

To examine the effect of modular surgical supply kits on operational efficiency and nursing standards, particularly in the context of preoperative preparation for thyroid surgery.

Key Findings:

• Preoperative preparation duration was significantly shorter in the experimental group (24 ± 4 min vs. 30 ± 5 min; P < 0.01).
• Omission rate was lower in the experimental group (0% vs. 2%; P = 0.04), but not significant after correction (adjusted P = 0.24).
• Nurse satisfaction was higher in the experimental group (92.1 ± 3.4 vs. 75.8 ± 4.2; P < 0.01).
• Surgeon satisfaction was also higher in the experimental group (86.5 ± 3.1 vs. 71.2 ± 4.5; P < 0.01).
• Operating room turnover time was reduced by 20% (12 ± 2 min vs. 15 ± 3 min; P = 0.01), but not significant after correction (adjusted P = 0.06).
• Intraoperative supplemental item requests decreased by 75% (0.3 ± 0.1 vs. 1.2 ± 0.3; P < 0.01; adjusted P < 0.0083).
• The proportion of returned unused consumables was lower in the experimental group (5% vs. 15%; P < 0.01; adjusted P < 0.0083).

Interpretation:

Modular surgical supply kits enhance preoperative workflow for thyroid procedures, improving efficiency, reducing waste, and potentially impacting clinical practice positively.

Limitations:

• Patient-level randomization may lead to contamination.
• Lack of blinding for certain outcomes.
• Absence of trial registration.
• Potential biases or confounding factors not addressed.

Conclusion:

Results indicate that modular surgical supply kits can improve preoperative efficiency in thyroid surgery, but further validation in a cluster-randomized trial is necessary to confirm these findings.
