The types of PICOT questions generally correspond to the type of clinical inquiry being made. Here's a breakdown of the common types:
-
Therapy/Intervention: These questions focus on the effectiveness of treatments, medications, or interventions.
-
Etiology/Harm: These questions investigate the causes or risk factors of a disease or condition (intervention being an exposure or risk factor).
-
Diagnosis: These questions assess the accuracy and reliability of diagnostic tests or procedures.
-
Prevention: These questions explore ways to reduce the risk of disease or complications.
-
Prognosis/Prediction: These questions predict the likely course or outcome of a disease or condition.
-
Meaning: These questions explore and seek understanding of a patient's experiences.
Here's a table summarizing the types:
| Type of PICOT Question | Focus | Example |
|---|---|---|
| Therapy/Intervention | Effectiveness of treatments | In adult patients with hypertension (P), does exercise (I) compared to medication (C) reduce blood pressure (O) over 6 months (T)? |
| Etiology/Harm | Causes or risk factors | Are children (P) exposed to second-hand smoke (I) compared to those not exposed (C) at higher risk of developing asthma (O) over their childhood (T)? |
| Diagnosis | Accuracy of diagnostic tests | In patients with suspected appendicitis (P), is a CT scan (I) compared to ultrasound (C) more accurate in diagnosing appendicitis (O) within 24 hours (T)? |
| Prevention | Reducing disease risk | In elderly patients (P), does the influenza vaccine (I) compared to no vaccine (C) reduce the incidence of pneumonia (O) during the flu season (T)? |
| Prognosis/Prediction | Predicting disease outcome | In patients diagnosed with early-stage Alzheimer's disease (P), does early intervention with cognitive training (I) compared to no intervention (C) slow cognitive decline (O) over 2 years (T)? |
| Meaning | Understanding patient experiences | How do adult patients (P) newly diagnosed with diabetes (I) describe their lived experiences (O)? |
