Abstract
Guidelines recommend intravenous (IV) ceftriaxone at a dose of 1–2 g/d as empirical treatment in adults hospitalized with community acquired pneumonia (CAP), with the addition of macrolide. We examined whether 1 g/d of IV ceftriaxone is associated with similar clinical outcomes to those of 2 g/d. This is a single-center, retrospective, cohort study of all adult patients hospitalized at Rabin Medical Center between 2015 and 2018 with CAP. The primary outcome was 30-day all-cause mortality. Risk factors for 30-day all-cause mortality were identified by univariable and multivariable analyses, using logistic regression analysis. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. A total of 2045 patients were treated with IV ceftriaxone 1 g/d and were and compared to 1944 patients who were treated with 2 g/d. The groups were comparable in their baseline characteristics and their clinical presentation. The 30-day all-cause mortality rate was similar between the groups (301/2045 (14.7%) for 1 g/d vs. 312/1944 (16.0%) for 2 g/d, p = 0.24). The rate of C. difficile infection (CDI) was significantly decreased with 1 g/d compared to 2 g/d (4/2045 (0.2%) vs. 12/1944 (0.6%), p = 0.03) and the length of stay was significantly shorter (median 4 days interquartile range (IQR) 3–7 vs. 5 days IQR 3–8, p = 0.02). None of the blood isolates of Streptococcus pneumoniae were penicillin or ceftriaxone resistant. For hospitalized patients with CAP, IV ceftriaxone 1 g/d was associated with similar mortality rates as IV ceftriaxone 2 g/d, with a decreased rate of CDI and shorter length of stay. Ceftriaxone 1 g/d may be sufficient to treat patients with CAP in countries with low prevalence of drug resistant Streptococcus pneumoniae.
