 P – Population refers to the sample of subjects you wish to recruit for your study. Consider disease, health status, age, gender, race, sexual orientation.
 I – Intervention refers to the treatment that will be provided to subjects enrolled in your study.  It may include tests, therapies, or medications.
C – Comparison identifies what you plan on using as a reference group to compare with your treatment intervention. Control group.
O – Outcome represents what result you plan on measuring to examine the effectiveness of your intervention. What do you hope to accomplish-recovery, fewer syptoms
T – Time describes the duration for your data collection.

Your PICOT question will fall under one of these types:

  • Therapy/Prevention
  • Diagnosis
  • Etiology
