Background Once daily dosing (ODD) of aminoglycosides has become a standard of care for most patient populations. However, the use of ODD of aminoglycosides has not been clarified in febrile neutropenia. Methods We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) that compared the effectiveness and safety of ODD versus multiple daily dosing (MDD) of aminoglycosides in patients with febrile neutropenia. We searched the PubMed, Scopus, Cochrane Central Register of Trials and clinicaltrials.gov databases up to July 2010. Results A total of five and eight RCTs were included in the effectiveness and safety analyses, respectively. We observed a trend towards better effectiveness of the ODD regimen in the clinically evaluable population {five RCTs, 403 patient-episodes, risk ratio (RR)?=?1.18 [95% confidence interval (95% CI): 0.98, 1.42]}, but not in the microbiologically evaluable population [three RCTs, 119 patient-episodes, RR?=?1.11 (95% CI: 0.84, 1.48)]. The occurrence of nephrotoxicity was similar between the two groups [seven RCTs, 1643 patient-episodes, RR?=?0.74 (95% CI: 0.36, 1.50)], as was ototoxicity [six RCTs, 862 patient-episodes, RR?=?1.05 (95% CI: 0.51, 2.19)]. There was no difference in mortality [four RCTs, 403 patient-episodes, RR?=?0.77 (95% CI: 0.21, 2.78)]. Conclusions Although the generalization of our findings may be restricted by the relatively small sample size and other methodological limitations of the included RCTs, ODD appears to be at least as effective and as safe as MDD in patients with febrile neutropenia. RCTs comparing ODD versus MDD in patients with bacteraemia and profound or prolonged neutropenia would be of additional value.
