Introduction :
The Automatic Control Test (ACT) is an essential component of steam sterilizer evaluation, ensuring compliance with HTM 01-01 Part C standard by verifying functionality and critical parameter tolerances. Traditionally, ACT involves collecting three sets of data “Recorded”, “Indicated” and “Measured” by manually inspecting cycle printouts, observing parameters displayed on the sterilizer screen, and using stopwatches to measure cycle stage durations. This approach is prone to human errors, lacks consistency, and time consuming. To address these setbacks, the Enhancement of Steam Sterilizer Automatic Control Test with Datalogger project was initiated, aiming to implement automation and enhance monitoring capabilities.
Objectives :
1. To Improve the current ACT process of steam sterilizer by introducing automation.
2. To simplify data collection, reducing time consumption, and digitizing the evaluation process.
3. To enhance monitoring capabilities.
Methodology :
1. Comprehensive review of the current ACT practice and an analysis of previous data to identify areas of improvement.
2. Utilize and customize the pre-existing in-house datalogger’s program to align with the local sterilizer settings, with the objective of achieving automation.
3. Establish critical parameters tolerance range in the datalogger program.
4. Create a database using Visual Basic for application (VBA), and establish alert levels for potential mechanical issues detection.
Result & Outcome :
1. Achieved higher efficiency and accuracy in monitoring steam sterilizer performance.
2. Minimized human errors in data input.
3. Established alert levels enable proactive monitoring of performance trends.
4. Facilitated the early detection of steam sterilizer mechanical issues.
5. Implemented proactive validation measures empowering preventive maintenance practices and reducing service breakdown.
6. Enhanced patient safety by continuously improving the quality of sterile supply services.
7. Achieved consistent adherence to required standards and reduced the risk of inadequate sterilization and potential infections.
8. Expanded the enhanced ACT project to TMH SSD and POH SSD.
