General Practice Patient Survey questionaAntibiotic prescribing volume, ADQ per STAR-PU per practice: adjusted regression coefficient, B valueb (95% CI)Extrapolated change in patient experience score, assuming a 25% reduction in antibiotic prescribing volume, %Extrapolated change in patient experience centile ranking, assuming a 25% reduction in antibiotic prescribing volume (patient experience centile values in brackets)

  • a Questionnaire numbers as they appear on the General Practice Patient Survey, 2011–2012; all scores based on the percentage values for the two most positive responses.

  • b All B values significant, P<0.01; all values adjusted for the practice and demographic variables included in the study. ADQ = average daily quantities. STAR-PU = specific therapeutic group age–sex related prescribing units.
