Purpose
Probiotics may prevent healthcare-associated infections, such as ventilator-associated pneumonia, Clostridioides difficile-associated diarrhea, and other adverse outcomes. Despite their potential benefits, there are no summative data examining the cost-effectiveness of probiotics in hospitalized patients. This systematic review summarized studies evaluating the economic impact of using probiotics in hospitalized adult patients.
Methods
We searched MEDLINE, EMBASE, CENTRAL, ACP Journal Club, and other EBM reviews (inception to January 31, 2019) for health economics evaluations examining the use of probiotics in hospitalized adults. Independently and in duplicate, we extracted data study characteristics, risk of bias, effectiveness and total costs (medications, diagnostics/procedures, devices, personnel, hospital) associated with healthcare-associated infections (ventilator-associated pneumonia, Clostridioides difficile-associated diarrhea and antibiotic-associated diarrhea). We used Grading of Recommendations Assessment, Development and Evaluation methods to assess certainty in the overall cost-effectiveness evidence.
Results
Of 721 citations identified, we included seven studies. For the clinical outcomes of interest, there was one randomized-controlled trial (RCT)-based health economic evaluation, and six model-based health economic evaluations. Probiotics showed favourable cost-effectiveness in six of seven (86%) economic evaluations. Three of the seven studies were manufacturer-supported, all which suggested cost-effectiveness. Certainty of cost-effectiveness evidence was very low because of risk of bias, imprecision, and inconsistency.
Conclusion
Probiotics may be an economically attractive intervention for preventing ventilator-associated pneumonia, Clostridioides difficile-associated diarrhea, and antibiotic-associated diarrhea in hospitalized adult patients. Nevertheless, certainty about their cost-effectiveness evidence is very low. Future RCTs examining probiotics should incorporate cost data to inform bedside practice, clinical guidelines, and healthcare policy.
