Abstract:
Objective To determine the causes and risk factors of antimicrobial treatment failure in patients with community-acquired pneumonia(CAP). Methods Hospitalized adults with CAP from January 2006 to December 2006 were analyzed retrospectively. Treatment failure was defined as appearance of nonresponding pneumonia and progressive pneumonia. Patient's clinical features were analyzed. Results All of 378 patients were involved in this study. Total antimicrobial treatment failure was happened in 50 patients(32 patients with non-responding pneumonia and 18 patients with progressive pneumonia). The causes were infectious (35 patients,70% ), non-infectious (11 patients,22% ) and undetermined (4 patients,8% ).Mortality of antimicrobial treatment failure was 18%(9/50, 8 patients died of infectious cause, 1 patient had no clear cause of death). Stepwise Logistic regression analysis showed that C-reactive protein, multilobar pneumonia,albumin < 30 g/L,renal function lesion,liver function lesion were related with antimicrobial treatment failure. Independent factors of treatment failure were multilobar pneumonia (P= 0.002) ,albumin <30 g/L(P = 0.001 ) and renal function lesion (P = 0.000). Conclusion The major challenge associated with antimicrobial treatment failure in hospitalized patients with CAP is infection, most of which is infection of drug resistant strain.
