Asking the Searchable Questions

Design searchable question using an evidence-based approach

PICO 

P Patient, population  (e.g., patient, population)
I Intervention  (e.g., medical, radiology diagnostic, other)
C Comparison  (e.g., alternative, other)
O Outcome (e.g., clinical outcome)
T Time (e.g., follow-up time)

EBR Search Inquiries and Studies Identification

Identify studies using an evidence-based approach

Question  Question Description  Study Design   
Therapy  the validity of the preventative or therapeutic effect, validity results (e.g., RCT), applicability for patient care. Also, to determine the effect of medical, surgical, or preventative interventions on patient-important outcomes (e.g., symptoms, function) RCT LHH, RRR, ARR, NNT, OR
Diagnosis the validity of the diagnostic study, the applicability of diagnostic test for patient care (sensitivity, specificity, precision, likelihood ration) prospective, blind controlled trial comparison to a gold standard  LR, OR
Prognosis the validity of the study results, the importance of the results, the applicability of results for patient care (determining the prognostic course) cohort study, case-control, case series, or case report  
Etiology/Harm the validity of harm study, the importance of the results, treatment course RCT, case-control, cohort studies  NNH, PEER
