Kanıta Dayalı Tıp Ekseninde Akılcı Laboratuvar Uygulamasının Hastane İşlem Maliyetleri Üzerindeki Etkisi: Bir Üniversite Hastanesinde Vaka Çalışması

Abstract

Objective: By integrating the rational laboratory system into hospital processes with evidencebased medicine applications, it is ensured that hospital resources are used more effectively and
 efficiently by preventing unnecessary test requests and reducing laboratory operation costs.
 Methods: The data in this qualitative study are the primary data and were obtained through
 document review and focus group (physician) interviews. The data in question were analyzed
 comparatively before the Rational Laboratory Application (RLA) (between 01.06.2018-
 31.12.2018) and after the RLA (between 01.06.2019-31.12.2019). The universe of the study
 consists of all the data in the laboratory of Düzce University Health Application and Research
 Center Hospital (DUHARCH). In this universe, the data evaluated for rational laboratory
 application constitute the sample of the research.
 Results: Before the RLA, a total of 446,300 test requests were made in the seven months (in
 2018) and the cost of these tests was determined to be 1,591,063 ₺ ($ 330,782.33). After the
 RLA, a total of 475,585 test requests were made in the seven months (in 2019), and the cost of
 these tests was determined to be 1,537,903 ₺ ($ 271,235.10). It was found that after RLA, there
 was a 6.56% increase in the number of examination requests compared to before RLA, but as an
 amount, costs fell by 3.34% on a ₺ basis and 22% on a $ basis. In the unit-based analysis, it was
 seen that successful units were surgical, and unsuccessful units were internal units that requested
 more tests.
 Conclusions: It was concluded that the rational laboratory system based on evidence-based
 medicine reduces hospital processing costs, provided that patient safety is protected, so this
 method can be a tool for more effective and efficient use of hospital resources.
