Exploring the appropriateness of antibiotic prescribing for common respiratory tract infections in UK primary care.

OBJECTIVES: To use illness severity scores to evaluate the appropriateness of antibiotic prescribing in UK general practice. METHODS: We describe variations in practice prescribing rates, taking account of illness severity. We used three scores in three studies to measure severity: 'FeverPAIN' in an adult acute sore throat cohort (n=12 829), the '3C score' in an adult acute lower respiratory tract infection cohort (n=28 883) and the STARWAVe score in an acute cough and respiratory infection children's cohort (n=8394). We calculated median ORs to quantify practice-level variation in prescribing rates, adjusted for illness severity. RESULTS: There was substantial variability in practice prescribing rates (ranges of 0%-97%, 7%-100% and 0%-75% in the three cohorts, respectively). There was evidence that higher prescribing practices saw a higher proportion of unwell patients. At the individual level, patients who were more unwell were more likely to receive a prescription, but prescribing levels for those with low scores were still high. The median OR was 2.5 (95% credible interval=2.2-2.9) in the sore throat data set, 2.9 (95% credible interval=2.6-3.2) in the adult cough data set and 2.1 (95% credible interval=1.8-2.4) in the children's cough data set. CONCLUSIONS: Higher prescribing practices may see more unwell patients with high illness severity scores, but the differences in scores account for a minority of between-practice prescribing variation. There is likely to be scope for further reductions in antibiotic prescribing among patients with low illness severity scores. Further research is needed to explore the additional factors that account for variation in prescribing levels.

Qualitative interview study of parents' perspectives, concerns and experiences of the management of lower respiratory tract infections in children in primary care.

OBJECTIVE: To explore parents' perspectives, concerns and experiences of the management of lower respiratory tract infections (LRTIs) in children in primary care. DESIGN: Qualitative semistructured interview study. SETTING: UK primary care. PARTICIPANTS: 23 parents of children aged 6 months to 10 years presenting with LRTI in primary care. METHOD: Thematic analysis of semistructured interviews (either in person or by telephone) conducted with parents to explore their experiences and views on their children being prescribed antibiotics for LRTI. RESULTS: Four major themes were identified and these are perspectives on: (1) infection, (2) antibiotic use, (3) the general practitioner (GP) appointment and (4) decision making around prescribing. Symptomatic relief was a key concern: the most troublesome symptoms were cough, breathing difficulty, fever and malaise. Many parents were reluctant to use self-care medication, tended to support antibiotic use and believed they are effective for symptoms, illness duration and for preventing complications. However, parental expectations varied from a desire for reassurance and advice to an explicit preference for an antibiotic prescription. These preferences were shaped by: (1) the age of the child, with younger children perceived as more vulnerable because of their greater difficulty in communicating, and concerns about rapid deterioration; (2) the perceived severity of the illness; and (3) disruption to daily routine. When there was disagreement with the GP, parents described feeling dismissed, and they were critical of inconsistent prescribing when they reconsult. When agreement between the parent and the doctor featured, parents described a feeling of relief and legitimation for consulting, feeling reassured that the illness did indeed warrant a doctor's attention. CONCLUSION: Symptomatic relief is a major concern for parents. Careful exploration of expectations, and eliciting worries about key symptoms and impact on daily life will be needed to help parents understand when a no antibiotic recommendation or delayed antibiotic recommendation is made.
