Hey there, fellow critical care pharmacists! Welcome to today’s literature briefing. I'm diving into an article titled “Evaluation of Stress Dose Hydrocortisone Tapers in Septic Shock,” published in _Hosp Pharm_. The lead author is Gilchrist and colleagues, and you can find it with P. M. I. D. four zero six seven one nine three six.
So, this was a retrospective cohort study, which included two hundred seventy-six I. C. U. patients with septic shock. All these patients received stress dose hydrocortisone for at least twenty-four hours between January first, two thousand twenty, and December thirty-first, two thousand twenty-three. The primary aim was to evaluate prescribing practices and the effect of hydrocortisone tapers on patient outcomes.
Let's get into the key findings. The median initial duration of hydrocortisone therapy was two days, with an interquartile range of one point five to three days. Interestingly, about fifty point four percent, or one hundred thirty-nine of the patients, received a hydrocortisone taper. The median taper duration for those patients was two days, ranging from one to three days. The most common way they tapered was by reducing dosing frequency, seen in fifty-six point eight percent of the patients who got a taper.
Now, for the outcomes: The study found that patients who underwent a taper had a statistically significant increase in vasopressor rate at twenty-four hours post-taper initiation or discontinuation. Specifically, that was thirty-seven point four percent in the taper group versus twenty-one point three percent in the non-taper group, with a P-value of zero point zero zero four. At forty-eight hours, the difference in vasopressor rate was twenty point three percent versus twelve point nine percent, but this wasn't statistically significant, with a P-value of zero point one four. Despite that early increase in vasopressor need, the taper group actually showed a decreased hospital mortality rate, with an odds ratio of zero point five five, ninety-five percent confidence interval zero point three three to zero point nine two. They also had a decreased I. C. U. mortality rate, with an odds ratio of zero point four seven, ninety-five percent confidence interval zero point two seven to zero point eight one. However, the taper group also experienced an increased I. C. U. length of stay, odds ratio one point zero four, ninety-five percent confidence interval one point zero two to one point zero six. And an increased duration of mechanical ventilation, odds ratio one point zero eight, ninety-five percent confidence interval one point zero three to one point one two. This is in addition to that increased vasopressor rate at twenty-four hours, with an odds ratio of two point two one, ninety-five percent confidence interval one point two nine to three point seven seven.
To put these findings in perspective, you know, stress dose hydrocortisone in septic shock has been a hot topic. A systematic review and meta-analysis of forty-five randomized controlled trials, encompassing over nine thousand five hundred patients, found that corticosteroids likely reduce short-term mortality and increase shock reversal at seven days. But, they also noted an increased risk of hyperglycemia and neuromuscular weakness. That's from PubMed, P. M. I. D. three eight two five zero two four seven. Regarding timing, a study on early versus late hydrocortisone found that early administration, within twelve hours, shortened vasopressor duration and I. C. U. slash hospital stays, though with no mortality difference. That's P. M. I. D. three four one zero nine eight five zero. And for discontinuation, a retrospective cohort study comparing abrupt versus taper discontinuation suggested abrupt cessation was linked to less vasopressor reinitiation and less hyperglycemia with tapering. That's P. M. I. D. three five nine two seven nine six three. So, there's definitely a nuanced picture out there when it comes to steroid use in this population.
So, what does this mean for us, as critical care pharmacists? Well, this study highlights the significant variability in current hydrocortisone tapering practices. It suggests that while a taper might lead to an early, transient increase in vasopressor requirements and a longer I. C. U. stay, it was also associated with decreased hospital and I. C. U. mortality. This really emphasizes the need for careful monitoring when tapering stress dose steroids. You know, we need to balance the short-term hemodynamic considerations with these longer-term mortality benefits that were observed. It really underscores the critical need for more standardized protocols and, frankly, further prospective research to help us optimize how we discontinue stress dose steroids in septic shock patients.
Of course, like any study, this one has its limitations. Being a retrospective design, there's always the potential for confounding and selection bias. And the inherent variability in tapering protocols across the patients limits the generalizability of these findings. However, it did include a relatively large patient cohort of two hundred seventy-six patients, and it provided a detailed evaluation of various tapering methods and durations, which are definitely strengths.
In conclusion, this retrospective evaluation indicates that while there's considerable variability in how stress dose hydrocortisone is tapered in septic shock, and tapering is associated with an increased early vasopressor rate, it also shows a statistically significant decrease in both hospital and I. C. U. mortality. This data strongly suggests the need for further research and the development of clear guidelines regarding stress dose steroid discontinuation. That's all for today's briefing, critical care pharmacists. Thanks for tuning in!
