Effects of internet-based training on antibiotic prescribing rates for acute respiratory-tract infections: a multinational, cluster, randomised, factorial, controlled trial

Summary Background 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. Methods 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. Results 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). Interpretation Internet training achieved important reductions in antibiotic prescribing for respiratory-tract infections across language and cultural boundaries.

European Surveillance of Antimicrobial Consumption (ESAC): disease-specific quality indicators for outpatient antibiotic prescribing

Background In 2007, ESAC (http://www.esac.ua.ac.be) published a set of 12 valid drug-specific quality indicators for outpatient antibiotic use in Europe. In this study, the authors aimed to develop evidence-based disease-specific quality indicators for outpatient antibiotic prescribing in Europe. Methods Two meetings were convened to produce a list of disease-specific quality indicators for outpatient antibiotic prescribing which conform to internationally agreed recommendations, building on a similar development of drug-specific quality indicators, and in collaboration with CHAMP and HAPPY AUDIT. 62 experts were asked to complete two scoring rounds of the proposed indicators on seven dimensions: their relevance to (1) reducing antimicrobial resistance, (2) patient health benefit, (3) cost-effectiveness, (4) policy makers, (5) individual prescribers, (6) their evidence base and (7) their range of acceptable use, using a scale ranging from 1 (=completely disagree) to 9 (=completely agree). Scores were judged according to the UCLA-RAND appropriateness method. Results For the six main indications for antibiotic prescribing (acute otitis media, acute upper-respiratory infection, acute/chronic sinusitis, acute tonsillitis, acute bronchitis/bronchiolitis, cystitis/other urinary infection) and for pneumonia, three quality indicators were proposed, the percentage prescribed (a) antibiotics; (b) recommended antibiotics; (c) quinolones. This set was scored by 40 experts from 25 countries. After one scoring round, all indicators were already rated as relevant on all dimensions, except one. Conclusion All proposed disease-specific quality indicators for outpatient antibiotic prescribing have face validity and are potentially applicable. They could be used to better describe antibiotic use and assess the quality of antibiotic prescribing patterns in ambulatory care.

Understanding by older patients of dialysis and conservative management for chronic kidney failure

Background Older adults with chronic kidney disease stage 5 may be offered a choice between dialysis and conservative management. Few studies have explored patients’ reasons for choosing conservative management and none have compared the views of those who have chosen different treatments across renal units. Study Design Qualitative study with semistructured interviews. Settings & Participants Patients 75 years or older recruited from 9 renal units. Units were chosen to reflect variation in the scale of delivery of conservative management. Methodology Semistructured interviews audiorecorded and transcribed verbatim. Analytical Approach Data were analyzed using thematic analysis. Results 42 interviews were completed, 4 to 6 per renal unit. Patients were sampled from those receiving dialysis, those preparing for dialysis, and those choosing conservative management. 14 patients in each group were interviewed. Patients who had chosen different treatments held varying beliefs about what dialysis could offer. The information that patients reported receiving from clinical staff differed between units. Patients from units with a more established conservative management pathway were more aware of conservative management, less often believed that dialysis would guarantee longevity, and more often had discussed the future with staff. Some patients receiving conservative management reported that they would have dialysis if they became unwell in the future, indicating the conditional nature of their decision. Limitations Recruitment of older adults with frailty and comorbid conditions was difficult and therefore transferability of findings to this population is limited. Conclusions Older adults with chronic kidney disease stage 5 who have chosen different treatment options have contrasting beliefs about the likely outcomes of dialysis for those who are influenced by information provided by renal units. Supporting renal staff in discussing conservative management as a valid alternative to dialysis for a subset of patients will aid informed decision making. There is a need for better evidence about conservative management to support shared decision making for older people with chronic kidney failure.

The antibiotic course has had its day

With little evidence that failing to complete a prescribed antibiotic course contributes to antibiotic resistance, it’s time for policy makers, educators, and doctors to drop this message, argue Martin Llewelyn and colleagues

Evaluation of a web-based intervention to reduce antibiotic prescribing for LRTI in six European countries: quantitative process analysis of the GRACE/INTRO randomised controlled trial

BackgroundTo reduce the spread of antibiotic resistance, there is a pressing need for worldwide implementation of effective interventions to promote more prudent prescribing of antibiotics for acute LRTI. This study is a process analysis of the GRACE/INTRO trial of a multifactorial intervention that reduced antibiotic prescribing for acute LRTI in six European countries. The aim was to understand how the interventions were implemented and to examine effects of the interventions on general practitioners’ (GPs’) and patients’ attitudes.MethodsGPs were cluster randomised to one of three intervention groups or a control group. The intervention groups received web-based training in either use of the C-reactive protein (CRP) test, communication skills and use of a patient booklet, or training in both. GP attitudes were measured before and after the intervention using constructs from the Theory of Planned Behaviour and a Website Satisfaction Questionnaire. Effects of the interventions on patients were assessed by a post-intervention questionnaire assessing patient enablement, satisfaction with the consultation, and beliefs about the risks and need for antibiotics.ResultsGPs in all countries and intervention groups had very positive perceptions of the intervention and the web-based training, and felt that taking part had helped them to reduce prescribing. All GPs perceived reducing prescribing as more important and less risky following the intervention, and GPs in the communication groups reported increased confidence to reduce prescribing. Patients in the communication groups who received the booklet reported the highest levels of enablement and satisfaction and had greater awareness that antibiotics could be unnecessary and harmful.ConclusionsOur findings suggest that the interventions should be broadly acceptable to both GPs and patients, as well as feasible to roll out more widely across Europe. There are also some indications that they could help to engender changes in GP and patient attitudes that will be helpful in the longer-term, such as increased awareness of the potential disadvantages of antibiotics and increased confidence to manage LRTI without them. Given the positive effects of the booklet on patient beliefs and attitudes, it seems logical to extend the use of the patient booklet to all patients.

General practitioners’ views on the acceptability and applicability of a web-based intervention to reduce antibiotic prescribing for acute cough in multiple European countries: a qualitative study prior to a randomised trial

BackgroundInterventions to promote prudent antibiotic prescribing by general practitioners (GPs) have often only been developed for use in one country. We aimed to develop an intervention which would be appropriate to implement in multiple European countries in order to offer greater benefit to practice whilst using fewer resources. The INTRO (INternet TRaining for antibiOtic use) intervention needed to deliver training to GPs in the use of C-Reactive Protein (CRP) near patient tests to help diagnose acute cough and in communication skills to help explain prescribing decisions to patients. We explored GPs’ views on the initial version of INTRO to test acceptability and potentially increase applicability for use in multiple countries before the start of a randomised trial.Method30 GPs from five countries (Belgium, England, the Netherlands, Poland and Spain), were interviewed using a “think aloud” approach. GPs were asked to work through the intervention and discuss their views on the content and format in relation to following the intervention in their own practice. GPs viewed the same intervention but versions were created in five languages. Data were coded using thematic analysis.ResultsGPs in all five countries reported the view that the intervention addressed an important topic, was broadly acceptable and feasible to use, and would be a useful tool to help improve clinical practice. However, GPs in the different countries identified aspects of the intervention that did not reflect their national culture or healthcare system. These included perceived differences in communication style used in the consultation, consultation length and the stage of illness at which patient typically presented.ConclusionAn online intervention to support evidence-based use of antibiotics is acceptable and feasible to implement amongst GPs in multiple countries. However, tailoring of the intervention to suit national contexts was necessary by adding local information and placing more emphasis on the fact that GPs could select the communication skills they wished to use in practice. Using think aloud methods to complement the development of interventions is a powerful method to identify regional contextual barriers to intervention implementation.

Clinicians' views and experiences of interventions to enhance the quality of antibiotic prescribing for acute respiratory tract infections

Evidence shows a high rate of unnecessary antibiotic prescriptions in primary care in Europe and the United States. Given the costs of widespread use and associated antibiotic resistance, reducing inappropriate use is a public health priority. We aimed to explore clinicians’ experiences of training in communication skills and use of a patient booklet and/or a C-reactive protein (CRP) point-of-care test to reduce antibiotic prescribing for acute respiratory tract infections (RTIs). We used a qualitative research approach, interviewing clinicians who participated in a randomised controlled trial (RCT) testing two contrasting interventions. General practice clinicians in Belgium, England, The Netherlands, Poland, Spain and Wales participated in the study. Sixty-six semi-structured interviews were transcribed verbatim, translated into English where necessary, and analysed using thematic and framework analysis. Clinicians from all countries attributed benefits for themselves and their patients to using both interventions. Clinicians reported that the communication skills training and use of the patient booklet gave them greater confidence in addressing patient expectations for an antibiotic by providing answers to common questions and supporting the clinician’s own explanations. Clinicians felt the booklet could be used for a variety of patients and for different types of infections. The CRP test was viewed as a tool to decrease diagnostic uncertainty, to support non-prescription decisions, and to reassure patients, but was only necessary when clinicians were uncertain about the need for antibiotics. Providing clinicians with training and support tools for use in practice was received positively and was valued by clinicians across countries. Interventions seemed to have influenced behaviour by increasing clinician knowledge about illness severity and prescribing, increasing confidence in making non-prescribing decisions when antibiotics were unnecessary, and enabling clinicians to anticipate positive outcomes when making such decisions. Addressing such determinants of behaviour change enabled interventions to be relevant for clinicians working across different contexts.ABSTRACTBACKGROUNDEvidence shows a high rate of unnecessary antibiotic prescriptions in primary care in Europe and the United States.

Exploring Patients' Views of a Cognitive Behavioral Therapy-Based Website for the Self-Management of Irritable Bowel Syndrome Symptoms

Background Cognitive behavioral therapy (CBT) has been shown to have positive effects on the management of irritable bowel syndrome (IBS) symptoms. A factorial pilot randomized placebo-controlled trial (called MIBS) tested the potential effectiveness of a self-management CBT-based website alongside two medications: methylcellulose and mebeverine, and a placebo. The results showed no significant differences in quality of life or symptom severity measures, but enablement and participant’s global assessment of relief was higher in the website groups. Objective To conduct a qualitative study nested within this trial, in order to explore patients’ views and experiences of using the CBT-based website to facilitate self-management of IBS. Methods Semistructured interviews were carried out with patients who had used the website with one session of nurse support (n=16) or the website alone (n=15) while participating in the MIBS trial. An inductive thematic analysis was conducted. Results We identified three types of engagement with the CBT-based website. One group of participants, mostly in the website-only condition, had limited or no engagement with the website. One group engaged with the content and advice on practical lifestyle changes. The final group of participants engaged with the content and advice on psychological aspects related to IBS. Similarities and differences between these three groups are explored. Conclusions Teaching self-management techniques through a Web intervention was received positively by most of the participants. Concepts linked to cognitive aspects of CBT appeared to be harder for participants to engage with. Participants who received nurse support rated the cognitive aspects more positively, suggesting that some therapy support alongside the website should be considered. However, the Web format was preferred by some who favored anonymity as well as those who appreciated the accessibility and ease of use of this type of management. Suggestions on how to encourage engagement with Web interventions are discussed.

Exploring patients’ views of primary care consultations with contrasting interventions for acute cough: a six-country European qualitative study

Background:In a pan-European randomised controlled trial (GRACE INTRO) of two interventions, (i) a point-of-care C-reactive protein test and/or (ii) training in communication skills and use of an interactive patient booklet, both interventions resulted in large reductions in antibiotic prescribing for acute cough.Aims:This process evaluation explored patients’ views of primary care consultations using the two interventions in six European countries.Methods:Sixty-two interviews were conducted with patients who had participated in the GRACE INTRO trial. Interviews were transcribed verbatim and translated into English where necessary. Analysis used techniques from thematic and framework analysis.Results:Most patients were satisfied with their consultation despite many not receiving an antibiotic. Patients appeared to accept the use of both intervention approaches. A minority, but particularly in the trial arm with both interventions, reported that they would wait longer before consulting for cough in future.Conclusions:Patients perceived that both interventions supported the general practitioner’s (GP’s) prescribing decisions by helping them understand when an antibiotic was, and was not, needed. Patients consulting with acute cough had largely positive views about the GP’s enhanced communication skills, which included understanding their concerns, and the use of a near-patient test as an additional investigation.
