Which of the following is NOT a risk factor for 30-day mortality in community-acquired pneumonia?

• A. Female sex
• B. Age >65 years
• C. Hypotension
• D. Confusion or disorientation

Answer: (A)

Focusing on factors that indicate severe illness in community-acquired pneumonia helps explain prognosis beyond just the infection itself. Age 65 or older, hypotension, and confusion or disorientation are classic signs of increased severity and are core components of widely used severity assessments (for example, CURB-65 includes age ≥65, confusion, and low blood pressure). These factors reflect greater vulnerability, possible organ dysfunction, and systemic infection, all of which raise the risk of dying within 30 days and guide decisions about hospitalization and treatment intensity. Female sex, on the other hand, does not independently predict higher 30-day mortality in typical CAP populations and is not used as a severity criterion in these scoring tools. Thus, it is not a risk factor for mortality in this context.
