The aim of the current study was to investigate the inappropriate use of antibiotics in adults with acute infectious diarrhea and to evaluate the association between the use of antibiotics and clinical features. To achieve this aim, we reviewed 4891 patients＇ medical records from Apr. 2008 to Oct. 2009. Of the total 4891 cases, 30.5% had clinical features of invasive bacterial diarrhea, 48.1% were prescribed with antibiotics, and 20.3% received inappropriate antibiotic treatment. Of note, 19% involved unnecessary antibiotic prescriptions in non-indicated cases, which accounted for 39.4% of all antibiotics prescribed in the total 4891 patients. There was no significant differences between physicians and medical trainees in the inappropriate use of antibiotics （P = 1.0）. Logistic regression analysis demonstrated that except for body temperature, other clinical symptoms including abdominal pain, tenesmus, and faecal WBC count （〉10 cells/HPF） were associated with the use of antibiotics. In addition, other clinical indicators including vomiting, stool frequency of 5-10 times/d, mucous stool, and fecal WBC count of 1-10 cells/HPF, which are not normally indicators for prescribing antibiotics, were also associated with the use of antibiotics. This might suggest that these symptoms were mistaken as features of invasive bacterial diarrhea, thus leading to the overuse of antibiotics.展开更多

The study attempts to clarify it. Stool specimens of adult patients with acute non-bloody diarrhea and stool examination showing 1-14 fecal WBC/HPF were collected for bacterial culture and viral detection. Patients included in this study were 196 cases with mean age of （37.9±17.4） years and 42.3% was women. The bacterial and viral detection rates were 63 （32.1%） and 21 （10.7%）, respectively. Of the isolated pathogens, campylobacteria was present in 14 （22.0%） samples and was the most common bacteria and calicivirus was found in 10 （47.6%） samples and was the most common virus. Based on single pathogens, 46 cases were caused by invasive pathogens, 26 cases were caused by non-invasive pathogens. The body temperature was significantly higher in feverish patients caused by invasive pathogens than those caused by non-invasive pathogens （（38.44-0.7） ℃ vs （37.74-0.4） ℃, P = 0.002）. The probability of diarrhea caused by invasive pathogens was higher in patients with T〉38.4℃ than those with T_〈38.4℃ （RR = 1.5）. When T〉38.4℃ is used as the threshold for antibiotic treatment, the misuse rate of antibiotics would decrease from 26.9% to 3.8% （P = 0.021）. So T〉38.4 ℃ may be used as a possible reference value for antibiotic treatment in adult patients with 1-14 fecal WBC/HPF of acute non-bloody diarrhea.展开更多
