Evaluation of knowledge levels of physicists about rational laboratory use

Evaluatıon Of Knowledge Levels Of Physıcısts About Ratıonal Laboratory Use Objective: The unnecessary and inappropriate tests required increase the cost and workload in the laboratories. Various methods have been developed for rational use of laboratories and reduction of unnecessary test requests. In this study, it was aimed to measure the awareness of physicians about rational laboratory use and the level of knowledge about the test request period for frequently requested tests in clinical practice. Marial and Method: The study was planned as a cross-sectional descriptive study. In this context, a questionnaire on 'Rational laboratory use' was applied to the physicians working at Turgut Özal Medical Center. The age, gender, specialties and professional experiences of the physicians were questioned. With multiple choice questions, the knowledge levels of the physicians regarding the demand periods of some frequently requested tests were questioned. The data were analyzed by Pearson chi square and Mann Whitney U test. Results: A total of 400 physicians were surveyed in internal and surgical braches. The average age of the physicians was 33.01 ± 5.97 (min = 22, max = 59) years. 3.3% of physicians answered the question about blood lipids, 80.8% HbA1c, 64.5% Urea / creatinine, about 40% vitamin D and vitamin B12 request period. 85.3% of the physicians were not aware of the rational laboratory test request procedure and 94% had not received any training on rational laboratory use. Conclusion: The level of knowledge of physicians about rational laboratory use is insufficient and they need to be trained about the test periods of tests.
