BACKGROUND: Hypoxemia may influence the prognosis of patients with mild pneumonia, regardless of the initial CURB-65 score (confusion, blood urea nitrogen > 20 mg/dL, respiratory rate > 30 breaths/min, blood pressure < 90/60 mm Hg, and age ≥ 65 y). OBJECTIVE: To determine the risk factors associated with hypoxemia and the influence of hypoxemia on clinical outcomes in hospitalized patients with mild pneumonia. METHODS: We performed a multicenter prospective cohort study of 585 consecutive hospitalized patients with mild pneumonia (CURB-65 groups 0 and 1). We stratified the patients according to the presence of hypoxemia, defined as a PaO2/FIO2 < 300 mm Hg on admission. We assessed the risk factors associated with hypoxemia, hypoxemia's influence on the course of pneumonia, and clinical outcomes (mortality, hospital stay, and need for intensive care unit admission), with multivariable regression. RESULTS: Fifty percent of the patients (294 cases) had hypoxemia on admission. The risk factors independently associated with hypoxemia were: bilateral radiological involvement (odds ratio 2.8, 95% CI 1.1-7.5), history of COPD (odds ratio 2.5, 95% CI 1.4-4.3), and hypoalbuminemia (odds ratio 2.0, 95% CI.1-3.5). The hypoxemic patients had longer hospital stay, higher intensive care unit admission rate, higher rate of severe sepsis, and higher mortality than the non-hypoxemic patients. CONCLUSIONS: Hypoxemia in patients with mild pneumonia is independently associated with several adverse clinical and radiological variables, and the hypoxemic patients had worse clinical outcomes than the non-hypoxemic patients. Therefore, additional attention should be paid to the presence of hypoxemia, regardless of a low CURB-65 score. © 2011 Daedalus Enterprises. Source

Background and objective: Severity assessment is made at the time of the initial clinical presentation in patients with community-acquired pneumonia (CAP). It is unclear how the gap between time of presentation and duration of symptoms onset may impact clinical outcomes. Here we evaluate the association of prolonged onset of symptoms (POS) and the impact on clinical outcomes among hospitalized patients with CAP. Methods: This was a prospective, multicentre study of CAP in Spain. The primary outcomes were the clinical factors associated with POS defined as days from symptoms onset to pneumonia diagnosis > 7 days. The secondary outcomes were intensive care unit (ICU) admission, the presence of suppurative complications, septic shock and 30-day mortality. Results: We enrolled 1038 patients diagnosed of CAP: 152 (14.6%) patients had a POS. In multivariate analysis, the presence of prior corticosteroid therapy, alcohol abuse, prior antibiotic therapy, and confusion, urea, respiratory rate, blood pressure and age 65 years or older score 0-1 was independently associated with POS. Patients with POS had a higher incidence of suppurative complications, but not of 30-day mortality when compared with a shorter onset of symptoms. Conclusions: Approximately 15% of patients diagnosed with CAP had POS. Risk factors associated with POS were previous corticosteroids and antibiotic therapy, alcoholism and less severe pneumonia. POS was associated with a higher rate of suppurative complications and less need for ICU admission. © 2014 Asian Pacific Society of Respirology. Source
