Mortality was low (three (0.5%) patients died) and other adverse events were rare (30 (5.2%) patients had complications, 13 (2.3%) were re-admitted and treatment failed in 13 (2.3%)). Complications were mostly related to pleural effusion and empyema, and re-admissions and treatment failures to comorbidities.\n                  <\/jats:p>\n                  <jats:p>Outpatients with CAP have a characteristic microbial pattern. Regular antipneumococcal coverage remains mandatory.
