Fungus Related Disease Questionnaire-7 (FRDQ-7)

 

SUMMARY: The following seven questions correlated with improvement after nystatin therapy in a controlled clinical study of the yeast syndrome by Santelmann et al. (2001). Patients first filled out the popular 70-item questionnaire published by Crook (1995), and were then treated with nystatin. Answers from patients who improved were compared to answers from patients who did not respond to therapy in a gradual statistical discrimination analysis. The statisticians concluded that only seven questions from the original 70-item questionnaire predicted a positive response to nystatin in 95% of the patients. The final list of seven questions below is a scientifically validated screening tool, not a diagnostic test. It is useful for identifying possible yeast syndrome patients for laboratory testing. These findings underscore the importance of doing controlled clinical studies to establish standards of medical care. Hopefully, in the years to come, more physicians will accept the fact that fungus-related disease symptoms merit diagnostic evaluation and appropriate treatment based on test results.
