title: Adherence to guidelines and its impact on outcomes in patients hospitalized with community-acquired pneumonia at a university hospital.
abstract: OBJECTIVE
  To evaluate the agreement between the criteria used for hospitalization of patients with community-acquired pneumonia (CAP) and those of the Brazilian Thoracic Association guidelines, and to evaluate the association of that agreement with 30-day mortality. Secondarily, to evaluate the agreement between the treatment given and that recommended in the guidelines with length of hospital stay, microbiological profile, 12-month mortality, complications, ICU admission, mechanical ventilation, and 30-day mortality.
  
  
  METHODS
  This was a retrospective study involving adult patients hospitalized between 2005 and 2007 at the Federal University of Minas Gerais Hospital das Clínicas, located in Belo Horizonte, Brazil. Medical charts and chest X-rays were reviewed.
  
  
  RESULTS
  Among the 112 patients included in the study, admission and treatment criteria were in accordance with the guidelines in 82 (73.2%) and 66 (58.9%), respectively. The 30-day and 12-month mortality rates were 12.3% and 19.4%, respectively. The 30-day mortality rate was lower for patients in whom the CRB-65 (mental Confusion, Respiratory rate, Blood pressure, and age > 65 years) score was 1-2 and the antibiotic therapy was in accordance with the guidelines (p = 0.01). Cerebrovascular disease and appropriate antibiotic therapy showed independent associations with 30-day mortality. There was a trend toward an association between guideline-concordant antibiotic therapy and shorter hospital stay.
  
  
  CONCLUSIONS
  In the population studied, admission and treatment criteria that were in accordance with the guidelines were associated with favorable outcomes in hospitalized patients with CAP. Cerebrovascular disease, as a risk factor, and guideline-concordant antibiotic therapy, as a protective factor, were associated with 30-day mortality.
