The adjusted OR for blood oxygen saturations <90% were also increased for the individual endpoints of 30-day mortality (2

In analyses adjusted for pneumonia severity, confirmation by chest radiograph, and receipt of guideline-concordant antibiotics, an oxygen saturation <90% was still independently associated with increased rates of 30-day mortality or hospitalization (adjusted odds ratio [OR] 1.7; 95% confidence interval [CI], 1.1–2.8; P = .032 [ Table 2]). 0; 95% CI, 0.7–5.4; P = .17) and hospitalization (1.7; 95% CI, 1.1–2.9; P = .030).

In a population-based cohort of nearly 3000 people with pneumonia managed according to a validated clinical pathway and discharged home to be treated as outpatients, we documented that 30-day rates of death or subsequent hospitalization were almost 10%. This finding was primarily a result of patients eventually returning to the ED and being admitted to hospital, but even 30-day mortality was 1%. We also found that hypoxemia defined as blood oxygen saturation <90% was associated with a statistically significant 70% increase (adjusted OR 1.7; P = .032) in 30-day mortality or hospitalization. This increased risk of major adverse events was independent of disease severity and appropriate antibiotic treatment. Our results validate the clinical weight that most physicians place on the presence of hypoxemia when it comes to making site-of-care decisions for cases of pneumonia [ 6, 10, 11, 18].

This study is exclusive with its try to file the risks of this hypoxemia during the a populace-depending take to of patients which have pneumonia addressed beyond your health.

Low oxygen saturation reflects an integrated noninvasive measure of the extent of lung parenchyma involvement by infection, consequent anatomic and physiologic derangements, and available cardiopulmonary functional reserve, and thus it seems to accurately capture the clinical severity of pneumonia. Indeed, most experts suggest that patients with pneumonia and hypoxemia should be admitted to the hospital for initial treatment and careful observation, and that an oxygen saturation <90% is an “absolute contraindication” to outpatient treatment [ 2]. In our study, however, it was not until the admission-to-hospital threshold was raised to 92% that oxygen saturation was no longer significantly associated with short-term morbidity and mortality. Although a 2% shift upward in oxygen saturation may seem inconsequential, in absolute terms in our population it represented an additional 7% of outpatients being admitted to hospital. Thus, the number-needed-to-admit to “prevent or ameliorate” 1 major adverse event would be 14.
