Medical literature frequently identifies advanced age as a poor prognostic factor in community-acquired pneumonia(CAP). The aim of this study was to evaluate the impact of age on the outcome of severe CAP.
A prospective observational study on all patients admitted to the intensive care unit (ICU) with severe CAP over a 20-month period. Patients were diagnosed to have severe CAP if they met a)one of two major criteria; septic shock or the need for mechanical ventilation OR b) two of three minor criteria; multilobar involvement, respiratory rate > 30/minute or PO2/FiO2 ratio<250.
There were 80 cases of severe CAP admitted to the ICU over this period. The ICU mortality rate was 30% (24 patients died, 56 survived). The average age of survivors was 59.4 years(SD 16.4) and of non-survivors was 61.7 years(SD 20.2). There was no statistical difference between the two groups (p value 0.58).CONCLUSIONS: In this study on severe CAP patients, there was no significant difference between the ages of survivors and non-survivors.
Advanced age is not an important risk factor for mortality in patients with severe CAP.
