Rational laboratory use means the rational use of laboratory services to ensure accurate diagnosis, avoid unnecessary examinations and reduce costs. The aim of the study is to evaluate durations of test results in incoming test requests and sample requests in the pathology laboratory routine in terms of their consistency with the preliminary diagnosis and to offer solutions regarding the rational use of the pathology laboratories.
The study is a cross-sectional descriptive study in which 814 thyroid FNAB (Fine Needle Aspiration Biopsy) requests received by a private pathology laboratory in Istanbul between 1 January 2017 and 31 December 2018 are evaluated retrospectively. According to pathology results, 35.8% of the cases are malignant (277 cases) and 64.2% (497 cases) are benign. The sensitivity and specificity of the test are calculated as 78.70%, 75.25%, respectively. Positive predictive value is calculated as 63.93%, negative predictive value as 76.37% and accuracy as 76.49%. No statistically significant consistency between pathology results of the cases and preliminary diagnosis results is identified. In other words, it is identified that there is no inconsistency in the analytical and post-analytical stages on laboratory side of the process that would affect the results of the pathology, but pathology laboratories are used rationally. The rational use of pathology laboratories depends on the well-managed management of all stages of workflow processes and the well-known solutions to problems. However, it is considered that the physician in charge of the clinical process of the patient should completely fill the requested information about the patient in the pathology forms during the request and that certain algorithms in cytopathologist-clinician communication should be used.
