The role of evidence in the decline of antibiotic use for common respiratory infections in primary care
No full textAntibiotic prescribing in primary care for common respiratory infections increased steadily until the mid 1990s, when the trend reversed noticeably. During the subsequent decade, antibiotic prescribing reduced by up to one-third in some countries. Explanations for this reduction have focused on a decline in the incidence and severity of common respiratory infections, and on the resulting decrease in the number of patients seeking consultation. We argue that evidence from primary-care research had a central role in changing the practice of antibiotic prescribing, and discuss the concern that has arisen among some physicians around this issue. Targeted reductions in antibiotic prescribing constitute a balancing act between individual and societal concerns, pitting the expected gains in preserving the usefulness of an antibiotic against any given reduction in use. There may be unintended consequences for decreasing antibiotic use beyond a certain point without adequate supporting evidence. A new approach to antibiotic prescribing requires comprehensive research to answer why change is necessary, and how that change can be safely implemented. Future policies must move beyond a ?one size fits all? mindset if public and provider behaviours are expected to become more congruent with the growing research evidence

Parental views on childhood vaccination against viral gastroenteritis-a qualitative interview study
No full textBackground. Gastroenteritis (GE) causes significant morbidity, especially in young children. A vaccine against rotavirus, a common cause of viral GE (vGE), was added to the childhood immunization schedule in the UK in July 2013 and further related vaccines are under development. Aim. To explore parents? beliefs about vGE and their attitudes towards vaccinating. Design and setting. Qualitative interview study with parents of children who had recently experienced an episode of GE. Method. Twenty-eight semi-structured interviews were conducted over the phone with parents. Interviews were audio-recorded, transcribed and analysed using standard thematic approaches. Results. Parents varied in their perception of the threat posed by GE, and parents who did not perceive GE as serious were less enthusiastic about vaccines. Other parents were supportive of vaccines in general and considered benefits to their child, their family and the wider community. Many parents said that they lacked knowledge about efficacy and effectiveness of GE vaccines but their underlying belief about the seriousness of illness motivated their attitudes. Conclusion. Acceptability of GE vaccines to parents could be improved by providing more information on both the burden of illness and the impact of rotavirus vaccine in other comparable countries
Clinical course of suspected viral sore throat in young adults: cohort study
No full textObjective. To evaluate the natural clinical course of suspected viral sore throat. Design. Prospective cohort study. Setting. Five military camps in Norway. Methods. In a randomized placebo-controlled trial comparing the effect of bovine colostrum tablets or placebo on non-streptococcal sore throat in young adults no statistically significant difference in illness duration was found. The participants were thus regarded as one cohort. The authors analysed 10.0 cm visual analogue scales (VAS) scores for ?sickness? and sore throat, using 1.0 cm as a cut-off for recovery. They furthermore explored whether the VAS for sore throat was a good test to discriminate between recovered/not recovered by use of a receiver operating characteristic (ROC) curve. Results. For sore throat, it was found that 51% had recovered by day 6 and 91% had recovered by day 8. Similarly for sickness, 65% had recovered by day 6 and 94% by day 8. The daily VAS scores for ?sickness? and sore throat were highly correlated (p = 0.001). The mean day of recovery from ?sickness? and sore throats (based on VAS scores) was 5.5 and 4.7 respectively and 5.3 based on the dichotomous outcome for throat pain. The ROC curve revealed that a VAS scoreâ€
Understanding flucloxacillin prescribing trends and treatment non-response in UK primary care: a Clinical Practice Research Datalink (CPRD) study
Full text linkThe volume of prescribed antibiotics is associated with antimicrobial resistance and, unlike most other antibiotic classes, flucloxacillin prescribing has increased. We aimed to describe UK primary care flucloxacillin prescribing and factors associated with subsequent antibiotic prescribing as a proxy for non-response.Clinical Practice Research Datalink patients with acute prescriptions for oral flucloxacillin between January 2004 and December 2013, prescription details, associated Read codes and patient demographics were identified. Monthly prescribing rates were plotted and logistic regression identified factors associated with having a subsequent antibiotic prescription within 28 days.3 031 179 acute prescriptions for 1 667 431 patients were included. Average monthly prescription rates increased from 4.74 prescriptions per 1000 patient-months in 2004 to 5.74 (increase of 21.1%) in 2013. The highest prescribing rates and the largest increases in rates were seen in older adults (70+ years), but the overall increase in prescribing was not accounted for by an ageing population. Prescribing 500 mg tablets/capsules rather than 250 mg became more common. Children were frequently prescribed low doses and small volumes (5 day course) and prescribing declined for children, including for impetigo. Only 4.2% of new prescriptions involved co-prescription of another antibiotic. Age (<5 and ≥60 years), diagnosis of 'cellulitis or abscess' or no associated code, and 500 mg dose were associated with a subsequent antibiotic prescription, which occurred after 17.6% of first prescriptions.There is a need to understand better the reasons for increased prescribing of flucloxacillin in primary care, optimal dosing (and the need to co-prescribe other antibiotics) and the reasons why one in five patients are prescribed a further antibiotic within 4 weeks
Reducing uncertainty in managing respiratory tract infections in primary care.
Full text linkRespiratory tract infections (RTIs) remain the commonest reason for acute consultations in primary care in resource-rich countries. Their spectrum and severity has changed from the time that antibiotics were discovered, largely from improvements in the socioeconomic determinants of health as well as vaccination. The benefits from antibiotic treatment for common RTIs have been shown to be largely overstated. Nevertheless, serious infections do occur. Currently, no clinical features or diagnostic test, alone or in combination, adequately determine diagnosis, aetiology, prognosis, or response to treatment. This narrative review focuses on emerging evidence aimed at helping clinicians reduce and manage uncertainty in treating RTIs. Consultation rate and prescribing rate trends are described, evidence of increasing rates of complications are discussed, and studies and the association with antibiotic prescribing are examined. Methods of improving diagnosis and identifying those patients who are at increased risk of complications from RTIs, using clinical scoring systems, biomarkers, and point of care tests are also discussed. The evidence for alternative management options for RTIs are summarised and the methods for changing public and clinicians' beliefs about antibiotics, including ways in which we can improve clinician-patient communication skills for management of RTIs, are described
Missed opportunities for earlier treatment? A qualitative interview study with parents of children admitted to hospital with serious respiratory tract infections
No full textObjective To identify potential opportunities for earlier intervention among children who develop a complicated respiratory tract infection (RTI). Design Qualitative, face-to-face, individual interview study, either in hospital or at home, with parents of children admitted to hospital with a complicated RTI. Setting Participants were recruited from a large UK teaching hospital, and described events (largely) prior to hospital admission. Participants Parents of 22 children (12 with empyema, 8 with pneumonia, 1 with peritonsillar abscess and 1 with mastoiditis). Results Parents' accounts revealed missed opportunities for timely treatment resulting from parental and health service associated factors. Themes relating to parental factors included problems assessing the severity of the illness (5 parents), beliefs about accessing health services (10 parents; including fear of appearing ?neurotic?, belief that their concerns would not be taken seriously, and belief that their child would not be prescribed antibiotics or would be prescribed antibiotics too readily) and feeling powerless to challenge clinical authority (7 parents). Health service associated factors included perceived problems accessing healthcare services (13 parents; including inadequate primary care triage, barriers to accessing timely consultations and past experience of problems accessing healthcare leading to failure to consult) and perceived poor quality clinical encounters (11 parents; including inadequate assessment and communication). Conclusion Addressing, where appropriate, these parental (skills, fears and beliefs) and health service (access and consultation quality) associated factors may lead to more prompt care for seriously ill children
