[Predictors associated with clinical deterioration in SARS patients].

BACKGROUND: To study the predictive factors associated with clinical deterioration in SARS patients. METHODS: The clinical data of 60 SARS patients were analyzed by logistic regression and Cox's proportional hazards analysis. RESULTS: In logistic regression models, both older age (P=0.009) and severe lymphopenia (P=0.004) were significant predictors of clinical deterioration. In Cox's proportional hazard models, severe lymphopenia was significant predictor associated with prolongation of stay in hospital. CONCLUSION: Older age and severe lymphopenia seem to be statistically significant for predicting the clinical deterioration in SARS patients.
