Objective: To measure patients' perceptions of patient centredness and the relation of these perceptions to outcomes. Design: Observational study using questionnaires. Setting: Three general practices. Participants: 865 consecutive patients attending the practices. Main outcome measures: Patients' enablement, satisfaction, and burden of symptoms. Results: Factor analysis identified five components. These were communication and partnership (a sympathetic doctor interested in patients' worries and expectations and who discusses and agrees the problem and treatment, Cronbach's α=0.96); personal relationship (a doctor who knows the patient and their emotional needs, α=0.89); health promotion (α=0.87); positive approach (being definite about the problem and when it would settle, α=0.84); and interest in effect on patient's life (α=0.89). Satisfaction was related to communication and partnership (adjusted β=19.1; 95% confidence interval 17.7 to 20.7) and a positive approach (4.28; 2.96 to 5.60). Enablement was greater with interest in the effect on life (0.55; 0.25 to 0.86), health promotion (0.57; 0.30 to 0.85), and a positive approach (0.82; 0.52 to 1.11). A positive approach was also associated with reduced symptom burden at one month (β=−0.25; −0.41 to −0.10). Referrals were fewer if patients felt they had a personal relationship with their doctor (odds ratio 0.70; 0.54 to 0.90). Conclusions: Components of patients' perceptions can be measured reliably and predict different outcomes. If doctors don't provide a positive, patient centred approach patients will be less satisfied, less enabled, and may have greater symptom burden and higher rates of referral. What is already known on this topic: Preliminary evidence suggests that patients' perceptions of patient centredness predict outcomes better than analysing what the doctor says in a consultation What this study adds: There are five distinct components of patients' perceptions that can be measured reliably: communication and partnership, personal relationship, health promotion, positive approach to diagnosis and prognosis, and interest in the effect on life Each component predicts different consultation outcomes If doctors don't provide a positive, patient centred approach patients will be less satisfied, less enabled, and may have greater symptom burden and use more health service resources

An estimated 47 million people worldwide were living with dementia in 2015,¹ while in the United States around 5.7 million people have Alzheimer dementia.² Modifiable risk factors, including hypertension, hearing loss, depression, diabetes, and smoking, account for around 35% of dementia cases.¹ Anticholinergic drugs are another potentially modifiable risk factor. This broad group of drugs acts by blocking the neurotransmitter acetylcholine in the central and peripheral nervous system and includes some antihistamines, antidepressants, and medications for gastrointestinal and bladder disorders. These medicines can have short-term adverse effects, including confusion and memory loss in older people,^3-6 but it is less certain whether long-term use increases the risk of dementia.

Mucosal-associated invariant T (MAIT) cells are abundant in humans and recognize bacterial ligands. Here, we demonstrate that MAIT cells are also activated during human viral infections in vivo. MAIT cells activation was observed during infection with dengue virus, hepatitis C virus and influenza virus. This activation—driving cytokine release and Granzyme B upregulation—is TCR-independent but dependent on IL-18 in synergy with IL-12, IL-15 and/or interferon-α/β. IL-18 levels and MAIT cell activation correlate with disease severity in acute dengue infection. Furthermore, HCV treatment with interferon-α leads to specific MAIT cell activation in vivo in parallel with an enhanced therapeutic response. Moreover, TCR-independent activation of MAIT cells leads to a reduction of HCV replication in vitro mediated by IFN-γ. Together these data demonstrate MAIT cells are activated following viral infections, and suggest a potential role in both host defence and immunopathology.

Objective: To identify patient's preferences for patient centred consultation in general practice. Design: Questionnaire study. Setting: Consecutive patients in the waiting room of three doctors' surgeries. Main outcome measures: Key domains of patient centredness from the patient perspective. Predictors of preferences for patient centredness, a prescription, and examination. Results: 865 patients participated: 824 (95%) returned the pre-consultation questionnaire and were similar in demographic characteristic to national samples. Factor analysis identified three domains of patient preferences: communication (agreed with by 88-99%), partnership (77-87%), and health promotion (85-89%). Fewer wanted an examination (63%), and only a quarter wanted a prescription. As desire for a prescription was modestly associated with desire for good communication (odds ratio 1.20; 95% confidence interval 0.85 to 1.69), partnership (1.46; 1.01 to 2.09), and health promotion (1.61; 1.12 to 2.31) this study may have underestimated preferences for patient centredness compared with populations with stronger preferences for a prescription. Patients who strongly wanted good communication were more likely to feel unwell (very, moderately, and slightly unwell; odds ratios 1, 0.56, 0.39 respectively, z trend P<0.001), be high attenders (1.70; 1.18 to 2.44), and have no paid work (1.84; 1.21 to 2.79). Strongly wanting partnership was also related to feeling unwell, worrying about the problem, high attendance, and no paid work; and health promotion to high attendance and worry. Conclusion: Patients in primary care strongly want a patient centred approach, with communication, partnership, and health promotion. Doctors should be sensitive to patients who have a strong preference for patient centredness—those vulnerable either psychosocially or because they are feeling unwell.

High-volume prescribing of antibiotics in primary care is a major driver of antibiotic resistance. Education of physicians and patients can lower prescribing levels, but it frequently relies on highly trained staff. We assessed whether internet-based training methods could alter prescribing practices in multiple health-care systems. After a baseline audit in October to December, 2010, primary-care practices in six European countries were cluster randomised to usual care, training in the use of a C-reactive protein (CRP) test at point of care, in enhanced communication skills, or in both CRP and enhanced communication. Patients were recruited from February to May, 2011. This trial is registered, number ISRCTN99871214. The baseline audit, done in 259 practices, provided data for 6771 patients with lower-respiratory-tract infections (3742 [55·3%]) and upper-respiratory-tract infections (1416 [20·9%]), of whom 5355 (79·1%) were prescribed antibiotics. After randomisation, 246 practices were included and 4264 patients were recruited. The antibiotic prescribing rate was lower with CRP training than without (33% vs 48%, adjusted risk ratio 0·54, 95% CI 0·42-0·69) and with enhanced-communication training than without (36% vs 45%, 0·69, 0·54-0·87). The combined intervention was associated with the greatest reduction in prescribing rate (CRP risk ratio 0·53, 95% CI 0·36-0·74, p<0·0001; enhanced communication 0·68, 0·50-0·89, p=0·003; combined 0·38, 0·25-0·55, p<0·0001). Internet training achieved important reductions in antibiotic prescribing for respiratory-tract infections across language and cultural boundaries.

Objective: To compare immediate with delayed prescribing of antibiotics for acute otitis media. Design: Open randomised controlled trial. Setting: General practices in south west England. Participants: 315 children aged between 6 months and 10 years presenting with acute otitis media. Interventions: Two treatment strategies, supported by standardised advice sheets—immediate antibiotics or delayed antibiotics (antibiotic prescription to be collected at parents' discretion after 72 hours if child still not improving). Main outcome measures: Symptom resolution, absence from school or nursery, paracetamol consumption. Results: On average, symptoms resolved after 3 days. Children prescribed antibiotics immediately had shorter illness (−1.1 days (95% confidence interval −0.54 to −1.48)), fewer nights disturbed (−0.72 (−0.30 to −1.13)), and slightly less paracetamol consumption (−0.52 spoons/day (−0.26 to −0.79)). There was no difference in school absence or pain or distress scores since benefits of antibiotics occurred mainly after the first 24 hours—when distress was less severe. Parents of 36/150 of the children given delayed prescriptions used antibiotics, and 77% were very satisfied. Fewer children in the delayed group had diarrhoea (14/150 (9%) v 25/135 (19%), χ ² =5.2, P=0.02). Fewer parents in the delayed group believed in the effectiveness of antibiotics and in the need to see the doctor with future episodes. Conclusion: Immediate antibiotic prescription provided symptomatic benefit mainly after first 24 hours, when symptoms were already resolving. For children who are not very unwell systemically, a wait and see approach seems feasible and acceptable to parents and should substantially reduce the use of antibiotics for acute otitis media.
