Abstract
BACKGROUND: Assessment of early response to treatment is crucial for the management of community-acquired pneumonia (CAP).
OBJECTIVE: To describe the predictors and the outcomes of early clinical stability.
METHODS: We did a secondary analysis of a multicentre randomized controlled trial on CAP treatment in which 580 patients hospitalized for moderately severe CAP were included. The association between demographic, clinical and biological variables available at inclusion and early clinical stability (stabilization of vital signs within 72 hours with predetermined cut-offs) was assessed by multivariate logistic regression. The association between early clinical stability and mortality, severe adverse events, and length of stay was also tested.
RESULTS: Younger age (OR 0.98, 95% CI 0.96-0.99), lower platelet count (OR per 10 G/L increment 0.96, 95% CI 0.94-0.98), lower respiratory rate (OR 0.94, 95% CI 0.90-0.97), absence of hypoxemia (OR 0.58, 95% CI 0.40-0.85), lower numbers of co-morbid conditions (OR 0.82, 95% CI 0.69-0.98) and signs or symptoms (OR 0.78, 95% CI 0.68-0.90) were significantly associated with early clinical stability. Patients with early clinical stability had lower 90-days mortality (3.4% vs. 11.9%, p<0.001), fewer admissions to the intensive care unit (2.7% vs. 8.0%, p = 0.005) and a shorter length of stay (6.0 days, IQR 4.0-10.0 vs. 10.0 days, IQR 7.0-15.0, p<0.001).
CONCLUSIONS: Patients with younger age, less co-morbidity, fewer signs or symptoms, less respiratory compromise, and a lower platelet count are more likely to reach early clinical stability. Patients without early clinical stability have a worse prognosis and warrant close scrutiny.
