Background: This research delves into the comprehensive evaluation of AD 0.5 ml syringes, crucial components in medical procedures. These syringes fall into the category of class IIa according to EUMDR and are classified as class II by USFDA. The focus is on assessing their compliance with regulatory standards such as the European Medical Device Regulation (EUMDR), International Organization for Standardization (ISO 13485), US Food and Drug Administration (USFDA), and guidelines from the Medical Device Single Audit Program (MDSAP). The study particularly scrutinizes the design, manufacturing, and performance aspects of these syringes, aligning with the rigorous requirements set by these regulatory bodies.
Methods: This single-arm observational study involved distributing 8,000 syringes to 52 hospitals across 8 counties in Kenya, healthcare personnel used the syringes on 2,714 patients. Data collection utilized a single usability feedback form comprising quantitative and qualitative questionnaires. Quantitative data included counts of syringes used, failed inspection checks, and device failures. Qualitative data focused on usability parameters such as protection and sterility, preparation, injection, and reuse/safety and disposal, rated on a scale from 1 to 5. Healthcare professionals eligible for the qualitative questionnaire had used the syringe on a minimum of 50 patients.
Results: The study evaluated the usability and customer satisfaction of the 0.5 mL Auto Disable Early Activation syringe from Revital Healthcare (EPZ) Limited. Quantitative analysis showed that all syringes performed as intended, with 0% failing during use. Quantitative analysis revealed no syringes failed during use, indicating a 0.0% failure rate. Qualitative feedback highlighted high ratings in usability tasks, including protection and sterility (97.78%), preparation (95.56%), injection (94.81%), and reuse/safety and disposal (95.93%). Overall customer satisfaction was rated positively, with an 87.78% satisfaction rate. Overall, the syringe received positive feedback for usability and customer satisfaction, highlighting its effectiveness and safety in medical procedures. Usability ratings, measured on a 5-point Likert scale (1 = Poor, 2 = Fair, 3 = Good, 4 = Very Good, 5 = Excellent), further support the syringe’s efficacy and safety. Both quantitative and qualitative analyses confirmed that none of the tested syringes exhibited performance failures, indicating no quality or reliability concerns with the product.
Conclusion: The findings of this research underscore the paramount importance of adherence to international standards in the design, manufacturing, and performance of AD 0.5 ml syringes. The emphasis on compliance with regulatory guidelines enhances the reliability and safety of these syringes, instilling confidence among manufacturers, healthcare professionals, and regulatory bodies. As the healthcare industry evolves, this research contributes to the ongoing dialogue on medical device assessment and compliance. Ultimately, the paper aims to promote improved patient safety and outcomes on a global scale, emphasizing the critical role of adherence to international standards in the ever-changing landscape of healthcare.
