Analyzing the impact of implementing the PDCA management model on maintenance quality during the maintenance period of pressure steam sterilizers.

Eight pressure steam sterilizers in the hospital were selected as study subjects. From August 2023 to July 2024, routine maintenance measures were implemented (routine group), and the PDCA management model (PDCA group) from August 2024 to July 2025. Through the Plan-Do-Check-Act cycle, the PDCA group implemented maintenance, monitoring improvements, and spot-check evaluations. The study compared the following metrics between the two management approaches: management quality, equipment failure rate, repair timeliness rate, and quality compliance rate.

The PDCA group achieved statistically significant higher quality scores than the routine group across all dimensions of pressure steam sterilizer management (P<0.05). The PDCA group exhibited lower equipment failure rates than the routine group, while demonstrating higher rates of timely repairs and quality compliance. Differences in equipment failure rates and timely repair rates were not statistically significant (P>0.05), whereas the difference in quality compliance rates was statistically significant (P<0.05).

In the management of pressure steam sterilizer, the implementation of PDCA cycle management mode can reduce the failure rate of the equipment, find problems in the inspection and execution, timely maintenance and treatment, so as to improve the quality of pressure steam sterilizer management, so that the equipment operates normally, and play a stable sterilization effect.
