Graded Task intervention Description of situation % GPs rating "Yes" (N = 163) % GPs using situation as basis for their management "plan" (N = 158)
Situation 1 Could you confidently end a consultation for a patient with an URTI without prescribing an antibiotic? 94 17
Situation 2 Could you confidently manage patients with URTIs without an antibiotic, who have already tried to self-medicate? 75 12
Situation 3 Could you confidently manage patients with URTIs without an antibiotic, who expect you to prescribe an antibiotic? 62 17
Situation 4 Could you confidently manage patients with URTIs without an antibiotic, whose symptoms are distressing them 45 17
Situation 5 Could you confidently manage patients with URTIs without an antibiotic, who have a past history of COPD 1 ? 9 30
