Factors effecting the duration of hospitalization and mortality in patients with community-acquired pneumonia
Abstract
Community-acquired pneumonia (CAP) is a common infectious disease with high morbidity and mortality. In this study, demographic features, underlying conditions, causative pathogens and factors affecting length of hospital stay and mortality were retrospectively investigated in patients who were diagnosed as CAP and followed-up in our unit between January 2005-December 2007. Among 97 patients 65 (67%) were male, 32 (33%) were female and the mean age was 62.7 (age range: 18-94) years. Patients were grouped according to criteria of Turkish Thoracic Society into four groups; 22 were group 2 (patients with risk factors, without aggrevating factors), 59 were group 3 (patients with aggrevating factors), and 16 were group 4 (patients who have necessity for intensive care) CAP. The patients have also been grouped according to criteria of American Thoracic Society (CURB-65 score = Confusion, Urea > 7 mmol/L, Respiratory rate > or = 30/min, low Blood pressure and being > or = 65 years old), as group I (n = 65), group II (n = 20), and group III (n = 12). During follow-up 11 (11.3%) patients required mechanical ventilation support and 6 (6.2%) patients have died. Causative pathogens were isolated from 14 (23.3%) out of 27 well-qualified sputum samples obtained from 60 patients who could produce sputum (8 Streptococcus pneumoniae, 2 methicillin-sensitive Staphylococcus aureus, 2 Klebsiella pneumoniae, 1 Haemophilus influenzae, 1 Moraxella catarrhalis). Thirty-seven of cases were treated…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 97 participants or records.
