AKILCI LABORATUVAR KULLANIMI AÇISINDAN GEREKSİZ TETKİK İSTEMLERİNİN RETROSPEKTİF ANALİZİ: SEROLOJİ LABORATUVARI ÖRNEĞİ
RETROSPECTIVE ANALYSIS OF UNNECESSARY TEST PROMPTS IN TERMS OF RATIONAL USE OF LABORATORY: SEROLOGY LABORATORY CASE

Summary/Abstract: Aim: Unnecessary test demands is an issue worth investigating in terms of the cost patient safety and employee safety. This research aims to analyze the examination demands requested by medical departments to microbiology laboratories in terms of necessity, cost and time with retrospective approach. Moreover, this is the first study performed by that amount of sample size. Method: A total of 2820 test requests made between 01.02.2015-10.02.2015 were analyzed retrospectively. This analysis was based on the history of the patient and past laboratory results. The generated data sets entered into SPSS 22 and Excel 2013 program results were obtained. "Redundancy status" of the test requests was determined by taking the clinic which demands the test, the gender, age, pre diagnosis and the diagnosis of the patients, all the medical information recorded in the hospital information management system taken into consideration. Findings: As a result of the analysis, total number of redundant test claims made was found to be 382; the rate is 13.5%. It has been shown that the shares of the medical departments in making unnecessary tests requests are (4.89%) for pediatrics department, (4.22%) for internal medicine department (2.06%) for family medicine department and (2.38%) for other departments. The cost of unnecessary testing took place in the organization during the afore mentioned period was 3083.20Tlwith current prices determined by 2015 Health Practices Notification. The annual cost of redundant tests was reaching 55497.60 TL. The loss of working hours' due to the unnecessary testing was calculated as 6146. Results: Redundant tests prompts made to the laboratory has created a financial burden for health service providers, clinicians’ unnecessary tests claims cause the loss of time and labor in laboratory work and constitutes loss of time and negative situations for healing process of patients. It is required clinicians to use diagnostic algorithms, test claims should be made on hospital information management systems only by clinicians. Health managers should focus on the waste of time and labor and develop proposals for solutions.
