ABSTRACT
Objective To study the value of Saccharomyces boulardii for the prevention of antibiotic-associated diarrhea in older inpatients.Methods A total of 163 older patients who were treated with wide-spectrum antibiotics at least three days during January 2014 to December 2015 were randomly divided into control and study group.In study group, 81 patients were administrated with oral Saccharomyces boulardii 500 mg twice a day for 21 days.The control group was of no intervention.Morbidity rate of antibiotic-associated diarrhea and Clostridium difficile-associated diarrhea, frequency and duration of diarrhea were recorded.Results The incidence of antibiotic-associated diarrhea in study group was significantly lower than that in control group [14.8%(12/81) vs 28.0%(23/82), P0.05] in two groups.The frequency and duration of diarrhea in the study group were significantly lower and shorter than those in control group[(4.3±1.7) times/day vs (6.9±2.0) times/day;(3.0±1.1) days vs (5.7±1.8) days, both P<0.01].Conclusion Saccharomyces boulardii may reduce the incidence of antibiotic-associated diarrhea therefore improving the symptom of diarrhea in older inpatients.
