We assessed the effectiveness of a Lactobacillus probiotic on charges of well being care facility–onset Clostridium difficile an infection (HO-CDI) in sufferers receiving antibiotics. A complete of 1576 sufferers had been evaluated. There was no distinction within the HO-CDI incidence between those that obtained probiotics and those that didn’t (1.8% vs 0.9%; P = .16).
Hospitals collaborating within the Facilities for Medicare and Medicaid Providers report well being care facility–onset Clostridium difficile an infection (HO-CDI) knowledge to the Nationwide Healthcare Security Community. The Society for Healthcare Epidemiology of America and the Infectious Ailments Society of America endorse suggestions to help acute care hospitals in implementing and prioritizing their CDI prevention efforts [1]. Though probiotics isn’t an endorsed technique, a latest complement printed in Medical Infectious Ailments recommends probiotics, particularly the mixture of Lactobacillus acidophilus CL1285, Lactobacillus casei LBC80R, and Lactobacillus rhamnosus CLR2 (Bio-Okay+), as an intervention to scale back CDI charges [2]. Based mostly on knowledge introduced, our establishment added Bio-Okay+ to the formulary, and as a part of a “bundle” to scale back danger of HO-CDI, Bio-Okay+ was really helpful to be administered to sufferers on antibiotic remedy recognized as excessive danger for CDI. As well as, schooling was supplied to medical employees relating to the supply of Bio-Okay+, and physicians might select to manage Bio-Okay+ at their discretion. This examine evaluated the charges of HO-CDI for a 6-month time interval amongst sufferers who obtained intravenous (IV) antibiotics plus Bio-Okay+ vs IV antibiotics alone.
METHODS
This was a retrospective cohort examine carried out at a 400-bed neighborhood hospital in La Jolla, California. All hospitalized sufferers handled with IV antibiotics through the examine interval had been evaluated for enrollment. Grownup sufferers (age ≥18 years) who obtained at the least 1 dose of antibiotics and had a size of keep >3 days had been included. Sufferers had been excluded if CDI was neighborhood onset (recognized inside 3 days of hospital admission) or in the event that they obtained cefazolin or cefoxitin for surgical prophylaxis solely. The first end result was the incidence of HO-CDI in sufferers who obtained IV antibiotics plus probiotics vs IV antibiotics alone. Bio-Okay+ was the one probiotic used was and was prescribed on the discretion of the attending doctor.
Baseline demographic knowledge, size of keep, age, Charlson Comorbidity Index, billed grams of antibiotics, acid inhibitor use, variety of days on probiotics, intensive care unit (ICU) keep, and in-house mortality had been evaluated. Sufferers had been recognized to have obtained IV antibiotics in the event that they obtained at the least 1 dose of the next: vancomycin, ciprofloxacin, levofloxacin, ceftriaxone, ceftazidime, cefepime, piperacillin/tazobactam, imipenem/cilastatin, meropenem, ertapenem, cefazolin, or cefoxitin. Sufferers had been thought of to be on probiotics earlier than the onset of HO-CDI if any doses of Bio-Okay+ had been recorded earlier than the date of Clostridium difficile toxin testing. The examine was accredited by the Scripps Institutional Overview Board.
Descriptive statistics had been used to research demographic knowledge throughout the two cohorts. Steady outcomes had been analyzed by 2-tailed Pupil t take a look at, and dichotomous knowledge had been analyzed by the Pearson χ2 take a look at or Fisher precise take a look at (for cell measurement <5). All statistical analyses had been carried out utilizing R: A Language and Setting for Statistical Computing, model 3.0.1 (Vienna, Austria) [3].
RESULTS
Between March 29, 2016, and September 30, 2016, a complete of 1576 sufferers handled with IV antibiotics had been evaluated, of whom 649 obtained antibiotics plus probiotics and 927 had been handled with antibiotics alone. Each teams had been related with respect to age (65.8 vs 67.2 years; P = .15), ICU keep (48.4% vs 49.2%; P = .75), and in-house mortality (8.2% vs 6.8%; P = .32). HO-CDI occurred in 11 of 649 sufferers who obtained antibiotics plus probiotics and in 8 of 927 sufferers handled with antibiotics alone (1.8% vs 0.9%, respectively; P = .16) (Desk 1). The median period of probiotic therapy was 8.1 days. Sufferers within the probiotic group had an extended size of keep, a better Charlson Comorbidity Index, and a better quantity of antibiotics billed (Desk 1).

To guage whether or not higher antibiotic publicity within the probiotic group offset a possible therapeutic profit, we carried out a subgroup evaluation. We in contrast HO-CDI charges within the probiotic group with charges within the high 30% of sufferers by antibiotic publicity (billed grams of antibiotics) within the antibiotic-alone group and noticed no distinction (5 of 284 sufferers, 1.8%; P = NS) in HO-CDI charges (Desk 1). Additional, the excessive–antibiotic publicity group had a considerably higher quantity of billed grams of antibiotics than the probiotic group (median, 34.5 vs 24.0 g; P < .001), regardless of related lengths of keep (median, 8 vs 9 days; P = .06).DISCUSSION
On this examine, we noticed no distinction within the charges of HO-CDI amongst hospitalized sufferers who obtained IV antibiotics, with or with out probiotics. One notable distinction, nonetheless, was that the probiotic group had higher antibiotic publicity, as measured by whole grams of antibiotics billed throughout their hospital keep. We tried to regulate for this distinction by evaluating CDI episodes with the subset of sufferers who had been uncovered to comparable or larger quantities of antibiotics because the probiotic group and, once more, noticed no distinction in HO-CDI charges.
This examine has limitations to contemplate. First, probiotic use was not standardized and was prescribed on the discretion of the attending doctor. A scientific overview by Shen et al. [4] discovered that probiotics had been best if given nearer to the primary antibiotic dose, with a decrement in efficacy for each day of delay in beginning probiotics. From our knowledge, we’re unable to find out the timing of probiotics relative to the primary dose of IV antibiotics. Probiotics had been administered utilizing a normal dose; nonetheless, compliance was not assessed. Second, meta-analyses have proven a modest profit in stopping first-episode CDI [4, 5], with no profit on therapy or prevention of recurrence [6]. On this examine, we evaluated HO-CDI and didn’t differentiate between preliminary and recurrent episodes. Third, probiotic use was not randomized and sufferers who obtained probiotics additionally had larger antibiotic exposures in contrast with those that didn’t. Doctor bias relating to the efficacy of probiotics ought to be acknowledged and deserves consideration if physicians with extra confidence in probiotic efficacy have totally different antibiotic prescribing patterns. Moreover, we didn’t evaluate the distribution of lessons of antibiotics administered between teams. Probiotic administration was not stratified by receipt of an antibiotic that will be related to a “higher risk” of HO-CDI, and the objective of this examine was to supply an general “global” evaluation of probiotic efficacy in our hospitalized inhabitants.
Regardless of these limitations, this examine precisely describes probiotic use at our establishment and could also be extra generalizable to real-world use of probiotics at different acute care hospitals. Meta-analyses demonstrating advantage of probiotics are closely weighted on 2 small constructive research by Gao et al. [7] and Rafiq et al. [8]. These research demonstrated very massive impact sizes of Lactobacillus-containing probiotics in contrast with placebo (95% [7] and 75% [8] discount in CDI, respectively) in populations with very excessive first-episode CDI prevalence charges (23.8% [7] and 40% [8], respectively). Our outcomes and CDI prevalence are extra in step with the PLACIDE examine and inhabitants [9]. This massive, multicenter, double-blinded, placebo-controlled trial randomized hospitalized sufferers to a probiotic containing 2 strains of Lactobacillus acidophilus and bifidobacteria vs placebo and noticed no distinction in CDI charges (12 of 1470 sufferers [0.8%] vs 17 of 1471 sufferers [1.2%]; P = .35). Latest CDI tips affirm the necessity to use warning in making use of examine outcomes with an abnormally excessive baseline incidence of CDI and conclude that there are inadequate knowledge presently to advocate probiotics for major prevention of CDI outdoors of medical trials [1].
Antibiotic use is a very powerful modifiable danger issue for CDI in acute care hospitals. The Facilities for Illness Management estimates that at the least 30% of antibiotic use is pointless [10]. Based mostly on these findings, our establishment eliminated all probiotics from the formulary. As an alternative, we recommend sturdy antimicrobial stewardship practices which might be proven to be efficacious and warning that probiotics could eat well being care sources with out including further profit.
