สถานการณ์การใช้ patient-derived quality control เพื่อประเมินคุณภาพผลการวิเคราะห์

Abstract

Background: A correct test result is essential mean it provides useful information. To ensure the reliability of testresults not only the internal quality control but also patient-derived quality control is applied.  The carrent situation of assessing analytical performance via patient-derived quality control was thoroughly investigated. Methods: Questionnaires were distributed to 650 Thai clinical laboratories. Data analysis was performed using Chi-square test on Microsoft Excel. Results: Thai clinical laboratory utilizes the patient-derived quality control differently. These 4items of CVI/CVG mixed sample daily patient’s mean and test distribution statistic were used less than 15%. Theprivate-hospital relation and delta check more often than the government-hospital laboratory (p<0.01). The major obstacles of utilizing the patient-derived quality control were knowledge deficiency time consuming in training and preparing the standard operating procedure heavy workload and expenditures. Conclusion: Clinical laboratories consider utilizing the patient-derived quality control as a usefultool. It is able to identifying many non-analytical errors.
