Hypothesis

What are the risk factors for testing positive for Clostridium difficile toxin among hospitalized patients in Singapore?

Conclusion

The study found a four-fold increase in the incidence of Clostridium difficile-associated disease among hospitalized patients in Singapore from 2001 to 2006.

Supporting Evidence

  • CDAD incidence rose from 1.49 to 6.64 cases per 10,000 patient-days from 2001 to 2006.
  • The percentage of CDT-positive samples increased from 7% to 11% during the same period.
  • Longer hospital stays were associated with positive CDT results.

Takeaway

The number of people getting sick from a certain germ in Singapore's hospitals has gone up a lot over the years, and we need to be careful about it.

Methodology

The study calculated incidence rates and conducted a case-control study comparing CDT-positive patients with negative controls.

Potential Biases

Potential bias from using hospital records and the selection of controls.

Limitations

The study was limited to one hospital and may not represent the entire population of Singapore.

Participant Demographics

Patients hospitalized at Tan Tock Seng Hospital, Singapore, from 2001 to 2006.
