Improving point-of-care testing accuracy through training and supervision

Title : Improving point-of-care testing accuracy through training and supervision

Abstract:

Point-of-care testing (POCT) involves conducting laboratory tests near the patient rather than in a central laboratory, offering faster turnaround times (TAT) and enabling immediate clinical decisions. However, POCT is often performed by non-laboratory personnel, increasing the risk of human errors that may impact diagnostic accuracy.

Several factors contribute to POCT errors, including incorrect patient identification, spontaneous patient number assignment, improper test procedures, and sample rejection. These errors can lead to misdiagnoses, delays in treatment, and compromised patient care. Addressing these challenges requires structured training, continuous monitoring, and systematic interventions.

This study evaluates the impact of POCT training programs, random observations, and the implementation of a personal identification code for medical staff on reducing common errors. The primary focus is on minimizing spontaneous patient number assignments and sample rejections, which are among the most frequently encountered issues in POCT.

Our results demonstrate that with consistent POCT manager supervision and intervention, there is a measurable reduction in both error types. Over time, the combination of structured training, real-time monitoring, and accountability measures significantly improves test accuracy and reliability. Additionally, the impact of interventions across most departments is reflected in the increase in calls to the POCT manager and the number of training sessions. However, the gradual decrease in these calls and training requests over time suggests that medical staff have become more competent, leading to improved result quality and overall efficiency.

In conclusion, effective training and systematic interventions play a crucial role in reducing POCT-related errors. Implementing a structured approach that includes continuous education, random audits, and staff accountability measures enhances test accuracy, improves diagnostic efficiency, and ultimately contributes to better patient outcomes.
