Antibiotic prescribing volumes as a determinant of patient experience scores (based on General Practice Patient Survey questions)
| General Practice Patient Survey questiona | Antibiotic 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) |
|---|---|---|---|
| Q21a: Rating of GP giving you enough time | 3.24 (2.73 to 3.74) | −0.81 | 5 centiles (50th centile: 89.2%; 45th centile 88.5%) |
| Q21b: Rating of GP listening to you | 3.19 (2.69 to 3.68) | −0.80 | 5 centiles (50th centile: 90.2%; 45th centile 89.5%) |
| Q21c: Rating of GP explaining tests and treatments | 3.48 (2.93 to 4.03) | −0.87 | 5 centiles (50th centile: 85.9%; 45th centile 85.1%) |
| Q21d: Rating of GP involving you in decisions about your care | 3.84 (3.20 to 4.48) | −0.96 | 5 centiles (50th centile: 78.7%; 45th centile 77.8%) |
| Q21e: Rating of GP treating you with care and concern | 4.07 (3.49 to 4.65) | −1.02 | 6 centiles (50th centile: 86.6%; 44th centile 85.5%) |
| Q22: Confidence and trust in GP | 2.39 (2.06 to 2.72) | −0.60 | 6 centiles (50th centile: 94.7%; 44th centile 94.1%) |
| Q28: Overall experience of GP surgery | 1.98 (1.43 to 2.53) | −0.50 | 3 centiles (50th centile: 91.0%; 47th centile 90.5%) |
| Q29: Recommending GP surgery to someone else | 3.08 (2.26 to 3.91) | −0.77 | 3 centiles (50th centile: 84.0%; 47th centile 83.3%) |
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.
