A team at the MUHC and the Jewish General Hospital takes a new look at the causal relationship between antibiotic use and C.聽difficile infections.

The latest study by Dr. Sandra Dial from the Research Institute of the MUHC, 缅北强奸, and Attending Staff in the Intensive Care Unit at the Jewish General Hospital, questions the assumption held by a vast majority of medical professionals that Clostridium difficile (C.difficile) infections are essentially always preceded by antibiotic use. This finding could have a major impact on how patients with diarrhea are evaluated upon their admission to the hospital. This study will appear in the October 6 issue of the Canadian Medical Association Journal (CMAJ).

The researchers analyzed only C. difficile infections acquired outside the hospital by patients aged 65 or older, and serious enough to require a hospitalization. Patients with hospital-acquired C.difficile infections were excluded because of the increased risk of infection and antibiotic use in the hospital environment.

Their results show that 53% of the patients studied had not been exposed to antibiotics during the 45 days preceding their C.difficile-related hospitalisation. A rate that decreased to 46% when the pre-hospitalization timeframe analysed was extended to 90 days. 鈥淭hese figures show that approximately 50% of community-acquired C. difficile infections are not related to antibiotic use,鈥� explained Dr. Dial. 鈥淲hile antibiotic use indeed plays an important role, other factors are likely to also be important. But we still need to determine what these other risk factors are.鈥�

More precisely, this study demonstrates that the highest risk of C. difficile infection due to antibiotic use occurs during the 30 days following treatment. According to Dr. Dial, 鈥淏eyond the 45-day period following treatment, the risk declines significantly鈥�.

鈥淲e believe that all patients suffering from diarrhea, particularly if severe enough to require a hospital visit, should be tested for C.difficile at their arrival in the hospital. Right now, testing is mainly done on patients who have taken antibiotics, which probably means that not everyone is receiving a correct diagnosis,鈥� warned Dr. Dial.

Dr Sandra Dial is the Director of Critical care medicine at the Montreal Chest Institute of the 缅北强奸 Health Centre (MUHC), and a researcher within the 鈥渃ardiovascular diseases and critical care鈥� and the 鈥渞espiratory health鈥� axis of the Research Institute of the MUHC. She is also an assistant professor at the Faculty of medicine at 缅北强奸.
