Abstract
We evaluated patients admitted through our ED for community-acquired pneumonia (CAP) to assess the relevance of an early procalcitonin (PCT) determination on patient's outcomes.
METHODS: We reviewed all patients admitted for CAP in a 10 years period (2008-2017). Patients were stratified according to age groups: (18-65 years; 65-84 years; and ≥85 years), CURB-65 score, need for ventilation, Sepsis-3 criteria at admission, enrollment period, blood culture in ED. In-hospital mortality rate and length of hospital stay (LOS) were compared between patients that had an early PCT determination in ED vs. patients admitted without.
RESULTS: Our study cohort consisted of 4056 CAP patients, age 76 [IQ range 64-84] years. We enrolled 1039 patients <65 years old, 2015 aged 65-84 years, and 1002 aged ≥85 years. Overall, the early PCT determination in ED was not associated to a reduced LOS (p=0.630), nor to a reduced mortality rate (p=0.134). However, in patients ≥ 85 years, the PCT determination in ED was associated with lower mortality in those with CURB-65 ≥ 2, and Charlson's score ≥ 2 (p=0.033 and p=0.002, respectively).
CONCLUSIONS: Although an early PCT assessment in ED was not associated with better outcomes in term of LOS and mortality in patients with CAP, our findings suggest that it might be associated with reduced mortality in patients ≥ 85 years with severe CAP or high comorbidity.
