PANDEMİ SÜRECİNDE TEMAS ÖYKÜSÜ OLMAYAN VE ASEMPTOMATİK HASTALARIN AMELİYAT ÖNCESİ KORONAVİRÜS TARANMASINDA GÖĞÜS BİLGİSAYARLI TOMOGRAFİSİ VE RT-PCR TESTİNİN DEĞERLENDİRİLMESİ
In the coronavirus pandemic, the presence of asymptomatic patients in the community makes it mandatory to perform preoperative COVID-19 screening for asymptomatic patients. In this study, it was aimed to determine the preoperative screening efficiencies of chest computed tomography (chest CT) and RTPCR test in patients without coronavirus symptoms.The files of patients who have undergone any surgical or interventional procedures in our hospital between April 20 and July 25 and who did not have symptoms of coronavirus were retrospectively reviewed. The demographic characteristics of the patients, chest CT and RT-PCR results were listed and evaluated. p <0.05 was considered statistically significant. Results of 103 patients scanned by both Chest CT and RT-PCR were compared. There were 12 patients with positive chest computed tomography findings. Only 4 of them had positive RT-PCR results. The sensitivity of chest CT was calculated as 100%, selectivity as 91.92% and positive predictive value as 33.33%. For RT-PCR, all of these values were 100% (p <0.05). According to our study data, the positive predictive value of chest CT use in pre-operative COVID-19 screening in asymptomatic patients was found to be low, and the positive predictive value of RT-PCR was found to be high.
