Abstract:
Objective To look for a reliable and convenient judgement criteria for the screening of cytomegalovirus pneumonia in order to reduce misdiagnosis and resulted mistherapy.Methods Process collected data on fifty-six cytomegalovirus pneumonia and forty-two common viruses induced asthmatic bronchitis cases by use of discriminant analysis to construct prediction model of diagnosis result.Results Only three indexes including age,lymph count and platelet count were selected into the model via sift.The performance of the established screening model showed as follows:sensitivity was 80.36％,specificity was 80.95％,misdiagnosis rate was 19.05％,false negative rate was 19.64％,diagnostic accordance rate was 80.61％.Conclusion Being concise and of strong maneuverability and high accuracy in prediction,cytomegalovirus pneumonia diagnosis model constructed through discriminant analysis can provide powerful screening means for medical staff.
