Abstract
Objectives: To investigate the predictors of general practitioner (GP) consultation and antibiotic use in those developing sore throat.Methods: We conducted a prospective population-based cohort study on 4461 participants in two rounds (2010–11) from 1897 households.Results: Participants reported 2193 sore throat illnesses, giving a community sore throat incidence of 1.57/ person-year. 13% of sore throat illnesses led to a GP consultation and 56% of these consultations led to antibiotic use. Participants most likely to have sore throats included women and children (e.g. school compared with retirement age); adjusted incidence rate ratio (aIRR) of 1.33 and 1.52, respectively. Participants with sore throat were more likely to consult their GP if they were preschool compared with retirement age [adjusted OR (aOR) 3.22], had more days of sore throat (aOR 1.11), reported more severe pain (aOR 4.24) or reported fever (aOR 3.82). Antibiotics were more often used by chronically ill individuals (aOR 1.78), those reporting severe pain (aOR 4.14), those reporting fever (aOR 2.58) or children with earache (aOR 1.85). Among those who consulted, males and adults who reported feeling anxious were more likely to use antibiotics; aOR 1.87 and 5.36, respectively.Conclusions: Only 1 in 10 people who have a sore throat see a doctor and more than half of those attending get antibiotics. Further efforts to curb antibiotic use should focus on reducing initial GP consultations through public information promoting safe self-management, targeted at groups identified above as most likely to attend with sore throats.
Highlights
More than one-third of all antibiotics prescribed for respiratory infections are because of sore throat,[1] and one in two patients presenting to their general practitioner (GP) with these symptoms receive antibiotics.[2,3] There is a national drive in the UK to reduce antibiotic prescribing,[4] based on high-level evidence

Subsequent analyses of antibiotic use were restricted to the sore throat episodes which resulted in GP consultation
Summary
More than one-third of all antibiotics prescribed for respiratory infections are because of sore throat,[1] and one in two patients presenting to their general practitioner (GP) with these symptoms receive antibiotics.[2,3] There is a national drive in the UK to reduce antibiotic prescribing,[4] based on high-level evidence. The last and only population-based study in England to investigate sore throat in the community was conducted in 1974 on 198 women aged 20–44 years over a 28 day observation period.[25,26,27] This small and select sample, with short follow-up, undertaken four decades ago does not provide sufficient information on community burden and risk factors for sore throat, subsequent GP consultation and antibiotic use to inform new public information campaigns We investigated these issues using a large population-based prospective national household survey including
