This covers a before-and-after study regarding a single-center practice change in an intensive care unit where their approach to severe sepsis was altered to a protocol including intravenous high-dose vitamin C (1.5g q6), intravenous thiamine (200mg q12), and hydrocortisone (50mg q6). Essentially, this institution hypothesized this combination might have beneficial physiologic effects and, after witnessing initial anecdotal improvement, switched to this aforementioned protocol. This report describes their outcomes in the context of comparing the treatment group to similar patients treated in the seven months prior.
In-hospital mortality for patients treated on the new protocol was 8.5%, whereas previously treated patients were subject to 40.4% mortality. Vasopressor use and acute kidney injury was similarly curtailed in the treatment group. That said, these miraculous findings – as they are exhorted in the EVMS press release – can only be considered as worthy of further study at this point. With a mere 47 patients in both treatment groups, a non-randomized, before-and-after design, and other susceptibilities to bias, these findings must be prospectively confirmed before adoption. When considered in the context of Ioannidis’ “Why Most Published Research Findings Are False”, caution is certainly advised.
I sincerely hope prospective, external validation will yield similar findings – but will likewise not be surprised if they do not.
