It includes 408 hospitalized patients with CAP, average age 61,3±16,7 years;59,6% men (n=243). Receiver operating characteristics (ROC) curve and t-test analysis were used.Results: PSI (AUC=0,866) is superior to CURB65 (AUC=0,844), CRB65 (AUC=0,831)and IDSA/ATS criteria (AUC=0,827)in predicting the need of intensive care (p<0,001). Mean PSI score in a hospital ward is 83,4 and in an ICU – 149,7; (t=-15,526; p<o,oo1).PSI and IDSA/ATS criteria can predict the total in-hospital mortality better than CURB65 and CRB65 (AUC=0,861; 0,859; 0,849 and 0,842, respectively). Mean PSI score in survivors is 88,4 and in non-survivors – 160,9 (t=-12,824; p<o,oo1). For early in-hospital death IDSA/ATS criteria are the best predicting tool (AUC=0,830).The PSI class, IDSA/ATS criteria, CURB65 and CRB65 scores classified 39,4%, 18,9%, 21,5% and 20,1% as severe CAP, respectively.Conclusion:Although PSI is the most reliable tool in predicting the need of intensive care, IDSA/ATS criteria have greater discriminatory power for the prognosis of early in-hospital mortality. Both, PSI and IDSA/ATS criteria, are similar in predicting total in-hospital mortality. ER -
