RT Journal Article SR Electronic T1 Factors related with prolongued length of stay in good prognosis community acquired pneumonia JF European Respiratory Journal JO Eur Respir J FD European Respiratory Society SP P2697 VO 42 IS Suppl 57 A1 Pedro J.

No differences in microbiological diagnosis, ICU admission, re-admission or mortality at 30 and 60 days. There were no differences in the clinical and laboratory results which play a role in the PSI score, with the exception of pleural effusion which was more frequent in patients with PLOS [13(19.1%) vs. 4(4.6%); p=0.004]. SLOS had a shorter duration of intravenous antibiotic therapy (10.3[SD 2.52]; vs. 15.57[SD 8.3 days)], p<0.001;and SLOS patients were treated more frequently with levofloxacin in monotherapy [58(66.7%) vs. 34 (50%); p=0.036]. Patients with SLOS were admitted more frequently if the reason for admission were presence of an unstable comorbidity (7[10.3%] vs. 2[2.3%]; p=0.035, tachycardia (6[8.8%] vs. 0; p=0.005), renal failure(11[16.2%] vs. 4[4.6%] or empyema’s suspicion (6[8.8%] vs. 0; p=0.005).Conclusions: Tachycardia, renal failure, pleural effusion, empyema suspicion and the presence of an unstable comorbidity as the reason for admissions, plus a lower treatment with levofloxacin are related with a prolonged hospitalization in low risk CAP patients admitted to hospital.
