Summary of the international clinical guidelines for the management of hospital-acquired and ventilator-acquired pneumonia.

A summary of the evidence and recommendations made in the ERS/ESICM/ESCMID/ALAT guidelines for the management of hospital-acquired pneumonia and ventilator-associated pneumonia http://ow.ly/S3zA30iZfLa.

International ERS/ESICM/ESCMID/ALAT guidelines for the management of hospital-acquired pneumonia and ventilator-associated pneumonia: Guidelines for the management of hospital-acquired pneumonia (HAP)/ventilator-associated pneumonia (VAP) of the European Respiratory Society (ERS), European Society of Intensive Care Medicine (ESICM), European Society of Clinical Microbiology and Infectious Diseases (ESCMID) and Asociación Latinoamericana del Tórax (ALAT).

The most recent European guidelines and task force reports on hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP) were published almost 10 years ago. Since then, further randomised clinical trials of HAP and VAP have been conducted and new information has become available. Studies of epidemiology, diagnosis, empiric treatment, response to treatment, new antibiotics or new forms of antibiotic administration and disease prevention have changed old paradigms. In addition, important differences between approaches in Europe and the USA have become apparent.The European Respiratory Society launched a project to develop new international guidelines for HAP and VAP. Other European societies, including the European Society of Intensive Care Medicine and the European Society of Clinical Microbiology and Infectious Diseases, were invited to participate and appointed their representatives. The Latin American Thoracic Association was also invited.A total of 15 experts and two methodologists made up the panel. Three experts from the USA were also invited (Michael S. Niederman, Marin Kollef and Richard Wunderink).Applying the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) methodology, the panel selected seven PICO (population-intervention-comparison-outcome) questions that generated a series of recommendations for HAP/VAP diagnosis, treatment and prevention.

Impact of amoxicillin therapy on resistance selection in patients with community-acquired lower respiratory tract infections: a randomized, placebo-controlled study.

OBJECTIVES: To determine the effect of amoxicillin treatment on resistance selection in patients with community-acquired lower respiratory tract infections in a randomized, placebo-controlled trial. METHODS: Patients were prescribed amoxicillin 1 g, three times daily (n = 52) or placebo (n = 50) for 7 days. Oropharyngeal swabs obtained before, within 48 h post-treatment and at 28-35 days were assessed for proportions of amoxicillin-resistant (ARS; amoxicillin MIC ≥2 mg/L) and -non-susceptible (ANS; MIC ≥0.5 mg/L) streptococci. Alterations in amoxicillin MICs and in penicillin-binding-proteins were also investigated. ITT and PP analyses were conducted. RESULTS: ARS and ANS proportions increased 11- and 2.5-fold, respectively, within 48 h post-amoxicillin treatment compared with placebo [ARS mean increase (MI) 9.46, 95% CI 5.57-13.35; ANS MI 39.87, 95% CI 30.96-48.78; P < 0.0001 for both]. However, these differences were no longer significant at days 28-35 (ARS MI -3.06, 95% CI -7.34 to 1.21; ANS MI 4.91, 95% CI -4.79 to 14.62; P > 0.1588). ARS/ANS were grouped by pbp mutations. Group 1 strains exhibited significantly lower amoxicillin resistance (mean MIC 2.8 mg/L, 95% CI 2.6-3.1) than group 2 (mean MIC 9.3 mg/L, 95% CI 8.1-10.5; P < 0.0001). Group 2 strains predominated immediately post-treatment (61.07%) and although decreased by days 28-35 (30.71%), proportions remained higher than baseline (18.70%; P = 0.0004). CONCLUSIONS: By utilizing oropharyngeal streptococci as model organisms this study provides the first prospective, experimental evidence that resistance selection in patients receiving amoxicillin is modest and short-lived, probably due to 'fitness costs' engendered by high-level resistance-conferring mutations. This evidence further supports European guidelines that recommend amoxicillin when an antibiotic is indicated for community-acquired lower respiratory tract infections.

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

BACKGROUND: 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. OBJECTIVE: 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). DESIGN: We used a qualitative research approach, interviewing clinicians who participated in a randomised controlled trial (RCT) testing two contrasting interventions. PARTICIPANTS: General practice clinicians in Belgium, England, The Netherlands, Poland, Spain and Wales participated in the study. APPROACH: Sixty-six semi-structured interviews were transcribed verbatim, translated into English where necessary, and analysed using thematic and framework analysis. KEY RESULTS: 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. CONCLUSION: 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.

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.

Trust, openness and continuity of care influence acceptance of antibiotics for children with respiratory tract infections: a four country qualitative study.

BACKGROUND: Clinician-parent interaction and health system influences on parental acceptance of prescribing decisions for children with respiratory tract infections (RTIs) may be important determinants of antibiotic use. OBJECTIVE: To achieve a deeper understanding of parents' acceptance, or otherwise, of clinicians' antibiotic prescribing decisions for children with RTIs. METHODS: Qualitative interviews with parents of child patients who had recently consulted in primary care with a RTI in four European countries, with a five-stage analytic framework approach (familiarization, developing a thematic framework from interview questions and emerging themes, indexing, charting and interpretation). RESULTS: Fifty of 63 parents accepted clinicians' management decisions, irrespective of antibiotic prescription. There were no notable differences between networks. Parents ascribed their acceptance to a trusting and open clinician-patient relationship, enhanced through continuity of care, in which parents felt able to express their views. There was a lack of congruence about antibiotics between parents and clinicians in 13 instances, mostly when parents disagreed about clinicians' decision to prescribe (10 accounts) rather than objecting to withholding antibiotics (three accounts). All but one parent adhered to the prescribing decision, although some modified how the antibiotic was administered. CONCLUSIONS: Parents from contrasting countries indicated that continuity of care, open communication in consultations and clinician-patient trust was important in acceptance of management of RTI in their children and in motivating adherence. Interventions to promote appropriate antibiotic use in children should consider a focus on eliciting parents' perspectives and promoting and building on continuity of care within a trusting clinician-patient relationship.

Strategies to promote prudent antibiotic use: exploring the views of professionals who develop and implement guidelines and interventions.

BACKGROUND: A variety of interventions have been developed to promote prudent antibiotic use, especially for respiratory tract infections (RTIs); however, it is not yet clear which are most acceptable and feasible for implementation across a wide range of contexts. This study elicited the views of experts, professionals who develop and implement guidelines and interventions, from five countries, on the development of RTI guidelines and interventions for implementing them. OBJECTIVES: The aim was to determine whether there are common features of interventions which experts consider useful in changing health professionals' behaviour, or whether there are important contextual differences in views. METHODS: Fifty semi-structured interviews explored experts' views and experiences of strategies across five countries. Interviews were carried out in person or over the phone, transcribed verbatim and translated into English, if not already in English, for analysis. RESULTS: Themes were remarkably consistent across the countries, and these could be summarized as five sets of recommendations: guidelines should be developed by health care professionals to better fit GPs' needs; address GP concerns about recommendations and explain the need for guidelines; design flexible interventions to increase feasibility across primary care practice; provide interventions which engage GPs; and provide consistent messages about antibiotic use for patients, professionals and the public. CONCLUSIONS: Key features need to be addressed when developing future guidelines and interventions in order to improve their implementation. Consistency in experts' views across countries indicates the potential for the development of interventions which could be implemented on a multinational scale with widespread support from key opinion leaders.

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.

BACKGROUND: Interventions 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. METHOD: 30 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. RESULTS: GPs 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. CONCLUSION: An 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.

GPs' views in five European countries of interventions to promote prudent antibiotic use.

BACKGROUND: A variety of interventions have been developed to promote a more prudent use of antibiotics by implementing clinical guidelines. It is not yet clear which are most acceptable and feasible for implementation across a wide range of contexts. Previous research has been confined mainly to examining views of individual interventions in a national context. AIM: To explore GPs' views and experiences of strategies to promote a more prudent use of antibiotics, across five countries. DESIGN AND SETTING: Qualitative study using thematic and framework analysis in general practices in Belgium, France, Poland, Spain, and the UK. METHOD: Fifty-two semi-structured interviews explored GPs' views and experiences of strategies aimed at promoting a more prudent use of antibiotics. Interviews were carried out in person or over the telephone, transcribed verbatim, and translated into English where necessary for analysis. RESULTS: Themes were remarkably consistent across the countries. GPs had a preference for interventions that allowed discussion and comparison with local colleagues, which helped them to identify how their practice could improve. Other popular components of interventions included the use of near-patient tests to reduce diagnostic uncertainty, and the involvement of other health professionals to increase their responsibility for prescribing. CONCLUSION: The study findings could be used to inform future interventions to improve their acceptability to GPs. Consistency in views across countries indicates the potential for development of an intervention that could be implemented on a European scale.

Summary of the international clinical guidelines for the management of hospital-acquired and ventilator-acquired pneumonia

Nosocomial pneumonia is a frequent infection that is classified into two groups [1]: HAP, which develops in hospitalised patients after 48 h of admission, and does not require (but may include) artificial ventilation at the time of diagnosis [2, 3]; and VAP, which occurs in intensive care unit (ICU) patients who have received mechanical ventilation for at least 48 h [2, 3]. HAP is the second most common hospital infection and has the highest crude mortality, while VAP is the most frequent cause of nosocomial infection in the ICU [2, 3]. Both types of pneumonia lengthen hospital stay and consume considerable health resources [2, 3]. Recently, the ERS, ESICM, ESCMID and ALAT published clinical guidelines on the therapeutic and management strategies for adult patients with HAP and VAP, designed to guide clinical decisions made not only by pulmonologists and intensivists but by all health professionals who treat these patients [2]. These clinical guidelines are evidence-based (Grading of Recommendations Assessment, Development and Evaluation) and follow the PICO ( population-intervention-comparison-outcome) model. Each section in this article refers to a specific PICO question addressed in the guidelines.
