Factors Affecting Knowledge of Sexually Transmitted Infection Transmissibility in Healthcare Providers: Results From a National Survey

January 10, 2006

The authors of the current study sought to examine health care providers' knowledge of the transmissibility of sexually transmitted infections (STIs) and to identify knowledge determinants.

From March through May 2004, a representative sample of Canadian health care providers completed questionnaires, producing a corrected response rate of 50.8 percent for physicians. STI workers returned 236 questionnaires.

The researchers found that the distribution of HIV estimates for physicians was positively skewed (mode=10 percent), while chlamydia estimates were widely dispersed. For STI workers, the distribution of HIV estimates was trimodal (0 percent, 50 percent, and 100 percent), whereas distribution of chlamydia estimates were negatively skewed (mode=100 percent). Overall, 1.4 percent (HIV) and 5.8 percent (chlamydia) of respondents provided estimates close to the actual transmission probabilities. More years of medical experience and higher STI prevalence estimates predicted higher transmissibility estimates (95 percent confidence intervals).

"That only a small percentage of health care providers are aware of the actual transmissibility of HIV and chlamydia has implications for improving medical and sexual health training," the authors concluded.
