title: [Pneumonia associated with health care versus community acquired pneumonia: different entities, distinct approaches].
abstract: Healthcare-associated pneumonia (HCAP) is now identified as a unique entity that differs from community-acquired pneumonia (CAP), and in many ways is similar to nosocomial pneumonia (NP). Patients with the diagnosis of CAP and HCAP admitted to our Pneumology Unit during one year were retrospectively analysed. The objective was to compare the characteristics and the approach of these two entities. 197 patients were included, 144 with CAP and 53 with HCAP. Sex, age, comorbilities, Pneumonia Severity Index (PSI) score, radiological involvement, bacteriology, treatment and outcomes were analysed in the 2 groups. Compared to CAP, HCAP was associated with more severe disease, a higher mortality rate and greater length of hospitalization. HCAP differed from CAP mainly in bacteriology and outcomes.
