【摘要】:正Although international clinical guidelines generally recommend performing bacterial stool culture in patients with acute diarrhea and fever and discourage routine antibiotic prescribing,clinical practice varies.Understanding practice patterns can help health officials assess the sensitivity of laboratory-based enteric infection surveillance systems and the need to improve antibiotic prescribing practices.We surveyed physicians in Guangdong province,China,to measure their practices for patients with acute diarrhea.A standardized questionnaire was used to interview physicians working in hospitals parricipating in a Salmonella surveillance system in Guangdong,China.The questionnaire asked physicians about their routine practice for patients with diarrhea,including how they managed the last patient they had seen with acute diarrhea.We calculated the odds ratio and 95%confidence interval for factors associated with ordering a stool culture and for prescribing antibiotics.We received surveys from 237 physicians across 22 hospitals in Guangdong.For the last patient with diarrhea whom they had evaluated,134(57%) reported ordering a stool culture.The most common reasons for not ordering a stool culture included that it takes too long to receive the result,that the patient is not willing to pay for the test,and that the patient's illness was too mild to warrant testing.Most physicians prescribed at least one medication for the last patient with diarrhea whom they had evaluated.Of the 237 physicians surveyed,153 (65%) prescribed antibiotics,135(57%) probiotics,and 115(49%),a gastric mucosal protective drug.In conclusion, physicians in Guangdong,China,reported high rates of ordering bacterial stool cultures from patients with diarrhea,possibly associated with their hospital's participation in a special sm'veillance project.The high rate of antibiotic prescribing suggests that efforts to promote judicious antibiotic use,such as physician education, are needed.
