Scoring system for sputum evaluation assessing specificity and sensitivity
Fidra, Dominika ; Trnková, Ivana (advisor) ; Maláska, Jan (referee)
The aim of this diploma thesis is to create a scoring system in sputum evaluation for general nurses in the intensive care unit. It is conceived as a diagnostic study that assesses the ability of the scoring system to accurately determine the ongoing condition - an infectious inflammatory disease. The collected biological material was compared with the gold standard - microbiology, by two independent persons. The result of the diagnostic study is a verified scoring system, where the color, consistency, admixtures and odor of the biological material of sputum are described for individual point evaluations. The main parameters of the diagnostic test - sensitivity, specificity and predictive value (positive and negative) - were used to verify the scoring system. For normal and pathological values, cut-off values were determined, according to which the value of sensitivity and specificity changed. By plotting the values on a graph and creating a ROC curve, it was found that with a cut off value of 1 and 2 for the first evaluator, the resulting area under the curve (AUC)=0.75. The result represents the scoring system according to the first evaluator as a good and effective test. The research was carried out at the anesthesiology and resuscitation clinic at the University Hospital of Kralovske Vinohrady...
