Implementing practice guidelines for appropriate antimicrobial usage: a systematic review

Implementation strategies for knowledge products in primary healthcare: a systematic review of systematic reviews (Preprint)

Background

The underuse or overuse of knowledge products leads to waste in health care, and primary care is no exception.

Objective

This study aimed to characterize which knowledge products are frequently implemented, the implementation strategies used in primary care, and the implementation outcomes that are measured.

Methods

We performed a systematic review (SR) of SRs using the Cochrane systematic approach to include eligible SRs. The inclusion criteria were any primary care contexts, health care professionals and patients, any Effective Practice and Organization of Care implementation strategies of specified knowledge products, any comparators, and any implementation outcomes based on the Proctor framework. We searched the MEDLINE, EMBASE, CINAHL, Ovid PsycINFO, Web of Science, and Cochrane Library databases from their inception to October 2019 without any restrictions. We searched the references of the included SRs. Pairs of reviewers independently performed selection, data extraction, and methodological quality assessment by using A Measurement Tool to Assess Systematic Reviews 2. Data extraction was informed by the Effective Practice and Organization of Care taxonomy for implementation strategies and the Proctor framework for implementation outcomes. We performed a descriptive analysis and summarized the results by using a narrative synthesis.

Results

Of the 11,101 records identified, 81 (0.73%) SRs were included. Of these 81, a total of 47 (58%) SRs involved health care professionals alone. Moreover, 15 SRs had a high or moderate methodological quality. Most of them addressed 1 type of knowledge product (56/81, 69%), common clinical practice guidelines (26/56, 46%) or management, and behavioral or pharmacological health interventions (24/56, 43%). Mixed strategies were used for implementation (67/81, 83%), predominantly education-based (meetings in 60/81, 74%; materials distribution in 59/81, 73%; and academic detailing in 45/81, 56%), reminder (53/81, 36%), and audit and feedback (40/81, 49%) strategies. Education meetings (P=.13) and academic detailing (P=.11) seemed to be used more when the population was composed of health care professionals alone. Improvements in the adoption of knowledge products were the most commonly measured outcome (72/81, 89%). The evidence level was reported in 12% (10/81) of SRs on 62 outcomes (including 48 improvements in adoption), of which 16 (26%) outcomes were of moderate or high level.

Conclusions

Clinical practice guidelines and management and behavioral or pharmacological health interventions are the most commonly implemented knowledge products and are implemented through the mixed use of educational, reminder, and audit and feedback strategies. There is a need for a strong methodology for the SR of randomized controlled trials to explore their effectiveness and the entire cascade of implementation outcomes.

Academic detailing interventions for opioid-related outcomes: a scoping review

BACKGROUND

Academic detailing (AD) is a tailored, interactive educational outreach intervention that may improve patient outcomes. Insight into the design of AD interventions and the extent to which they are effective can help inform future AD-based programmes. The objective of this scoping review was to characterize opioid-focused AD interventions and describe their findings.

METHODS

A scoping review focused on AD interventions for opioids was conducted in PubMed, EMBASE and CINAHL databases through July 1, 2021. Studies were eligible for inclusion if written in English, included interactive opioid-focused educational interventions, and were conducted either in person, virtually or via telephone. Four independent reviewers reviewed titles and abstracts. Data extraction from full-text publications was completed using a standardized form.

RESULTS

Of 6086 articles initially identified, 22 articles met the inclusion criteria and 20 unique interventions were identified. The AD intervention was either delivered one-on-one (n=16) or in a small, interactive group setting (n=4). AD interventions varied in design. Effectiveness was evaluated in terms of opioid and naloxone prescribing rates, provider knowledge gaps, provider adherence to guidelines, and intervention feasibility. Sixteen (80%) interventions resulted in statistically significant improvement in one or more outcomes.

CONCLUSION

Generally, opioid-related AD was effective and programmes were primarily conducted one-on-one between pharmacists and primary care providers for 16-30 minutes. A variety of metrics and outcomes were used to assess the success/effectiveness of AD interventions, which is an important consideration in future studies as no single metric captures the effectiveness of an educational outreach-based intervention for pain management.

Strategies Used for Implementing and Promoting Adherence to Antibiotic Guidelines in Low- and Lower-Middle-Income Countries: A Systematic Review

Containing antimicrobial resistance and reducing high levels of antibiotic consumption in low- and lower middle-income countries are a major challenge. Clinical guidelines targeting antibiotic prescribing can reduce consumption, however, the degrees to which clinical guidelines are adopted and adhered to are challenging for developers, policy makers and users. The aim of this study was to review the strategies used for implementing and promoting antibiotic guideline adherence in low- and lower middle-income countries. A review of published literature was conducted using PubMed, Cochrane Library, SCOPUS and the information systems of the World Health Organization and the Australian National University according to PRISMA guidelines and our PROSPERO protocol. The strategies were grouped into five broad categories based on the Cochrane Effective Practice and Organization of Care taxonomy. The 33 selected studies, representing 16 countries varied widely in design, setting, disease focus, methods, intervention components, outcomes and effects. The majority of interventions were multifaceted and resulted in a positive direction of effect. The nature of the interventions and study variability made it impossible to tease out which strategies had the greatest impact on improving CG compliance. Audit and feedback coupled with either workshops and/or focus group discussions were the most frequently used intervention components. All the reported strategies are established practices used in antimicrobial stewardship programs in high-income countries. We recommend interrupted time series studies be used as an alternative design to pre- and post-intervention studies, information about the clinical guidelines be made more transparent, and prescriber confidence be investigated.

Impact of Educational Intervention to Promote Jordanian Community Pharmacists' Knowledge and Perception Towards Antimicrobial Stewardship: Pre-Post Interventional Study

OBJECTIVE

The aim of this study was to assess the impact of an online educational workshop on improving the knowledge, and perception of community pharmacists in Jordan towards the antimicrobial stewardship (AMS) and enhancing their ability to appropriately select correct antibiotic therapy.

METHODS

This is a pre-post study that was conducted in Jordan in December 2020. An electronic questionnaire was used to assess the awareness, perception of community pharmacists towards AMS, and their ability to appropriately select correct antibiotic before and after the educational workshop. The two-days' workshop was conducted on Zoom application. Analysis was conducted using Wilcoxon signed-rank test, McNemar's test using SPSS version 22.

RESULTS

During the study period, 100 community pharmacists attended the educational workshop. Pharmacists' knowledge was assessed prior to their participation which revealed a relatively good knowledge score with a median score of 6/10 (IQR = 4); their scores have improved significantly following the educational workshop with a median score of 7/10 (IOR = 2), p-value<0.001. Although one-third of the participants knew the definition of AMS prior to the workshop, almost half of the respondents (n = 56, 56%) knew the definition after the educational workshop. Regarding community pharmacist's ability to appropriately select correct antibiotic therapy, they showed a significant improvement in selecting the optimal antimicrobial for the virtual cases following the workshop (p-value < 0.05). Perceptions towards AMS were consistently positive before and after the workshop.

CONCLUSION

This study revealed the benefit of AMS-focused workshops for improving community pharmacists' knowledge and appropriate antibiotic prescribing. Thus, efforts are required to implement more AMS educational workshops for community pharmacists.

Implementation of national childbirth guidelines in Brazil: barriers and strategies

The present report describes the process and results obtained with a knowledge translation project developed in three stages to identify barriers to the Implementation of the National Guidelines for Normal Childbirth in Brazil, as well strategies for effective implementation. The Improving Programme Implementation through Embedded Research (iPIER) model and the Supporting Policy Relevant Reviews and Trials (SUPPORT) tools provided the methodological framework for the project. In the first stage, the quality of the Guidelines was evaluated and the barriers preventing implementation of the recommendations were identified through review of the global evidence and analysis of contributions obtained in a public consultation process. In the second stage, an evidence synthesis was used as the basis for a deliberative dialogue aimed at prioritizing the barriers identified. Finally, a second evidence synthesis was presented in a new deliberative dialogue to discuss six options to address the prioritized barriers: 1) promote the use of multifaceted interventions; 2) promote educational interventions for the adoption of guidelines; 3) perform audits and provide feedback to adjust professional practice; 4) use reminders to mediate the interaction between workers and service users; 5) enable patient-mediated interventions; and 6) engage opinion leaders to promote use of the Guidelines. The processes and results associated with each stage were documented and formulated to inform a review and update of the Guidelines and the development of an implementation plan for the recommendations. Effective implementation of the Guidelines is important for improving the care provided during labor and childbirth in Brazil.

Antibiotic prescribing and dispensing for acute respiratory infections in children: effectiveness of a multi-faceted intervention for health-care providers in Vietnam

Background: Appropriate antibiotic use is vital to effectively contain antibiotic resistance and improve global health. Acute respiratory infections (ARIs) remain the leading cause of disease and death in children under five in low-income countries.

Objective: To evaluate a multi-faceted intervention targeting health-care-providers’ (HCPs) knowledge, practical competences and practices regarding antibiotic use for ARIs.

Methods: A multi-faceted educational intervention with a two-armed randomised controlled design targeting HCPs treating ARIs in children was conducted in Bavi district, a rural district in Northern Vietnam in 2010–2011. Thirty-two communes of the district were randomized into two arms, with 144 HCPs in the intervention arm and 160 in the control arm. The intervention, conducted over seven months, comprised: (i) education regarding appropriate-antibiotic use, (ii) case scenario discussion and (iii) poster distribution. Questionnaires to assess knowledge and dispensing/prescribing forms to assess practice were completed before-and after interventions. The main outcome measures were differences in improvement in knowledge and practice in the intervention and control group, respectively.

Results: Knowledge improved in the intervention group for ARI aetiology by 28% (Δ_{Decrement control arm} 10%), antibiotic use for mild ARIs by 15% (Δ_{Decrement control arm} 13%) and for severe ARIs by 14% (Δ_{Improvement control arm} 29%). Practical competence for a mild ARI case scenario improved in the intervention and control groups by 20% and 11%, respectively. Total knowledge score increased statistically in the intervention group (Δ_{mean improvement} 1.17); less so in the control group (Δ_{mean improvement} 0.48). Practice regarding antibiotics for mild ARIs improved by 28% in the intervention group (Δ_{Decrement control arm} 3%).

Conclusions: The intervention significantly improved HCPs’ knowledge of ARIs and practice of antibiotic use in treatment of ARIs. We suggest mixed method assessment and long-term follow-up of these interventions to enable better appreciation of the effects and effect sizes of our interventions.

Clinician-targeted interventions to influence antibiotic prescribing behaviour for acute respiratory infections in primary care: an overview of systematic reviews

BACKGROUND

Antibiotic resistance is a worldwide health threat. Interventions that reduce antibiotic prescribing by clinicians are expected to reduce antibiotic resistance. Disparate interventions to change antibiotic prescribing behaviour for acute respiratory infections (ARIs) have been trialled and meta-analysed, but not yet synthesised in an overview. This overview synthesises evidence from systematic reviews, rather than individual trials.

OBJECTIVES

To systematically review the existing evidence from systematic reviews on the effects of interventions aimed at influencing clinician antibiotic prescribing behaviour for ARIs in primary care.

METHODS

We searched the Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects (DARE), MEDLINE, Embase, CINAHL, PsycINFO, and Science Citation Index to June 2016. We also searched the reference lists of all included reviews. We ran a pre-publication search in May 2017 and placed additional studies in 'awaiting classification'.We included both Cochrane and non-Cochrane reviews of randomised controlled trials evaluating the effect of any clinician-focussed intervention on antibiotic prescribing behaviour in primary care. Two overview authors independently extracted data and assessed the methodological quality of included reviews using the ROBIS tool, with disagreements reached by consensus or by discussion with a third overview author. We used the GRADE system to assess the quality of evidence in included reviews. The results are presented as a narrative overview.

MAIN RESULTS

We included eight reviews in this overview: five Cochrane Reviews (33 included trials) and three non-Cochrane reviews (11 included trials). Three reviews (all Cochrane Reviews) scored low risk across all the ROBIS domains in Phase 2 and low risk of bias overall. The remaining five reviews scored high risk on Domain 4 of Phase 2 because the 'Risk of bias' assessment had not been specifically considered and discussed in the review Results and Conclusions. The trials included in the reviews varied in both size and risk of bias. Interventions were compared to usual care.Moderate-quality evidence indicated that C-reactive protein (CRP) point-of-care testing (risk ratio (RR) 0.78, 95% confidence interval (CI) 0.66 to 0.92, 3284 participants, 6 trials), shared decision making (odds ratio (OR) 0.44, 95% CI 0.26 to 0.75, 3274 participants, 3 trials; RR 0.64, 95% CI 0.49 to 0.84, 4623 participants, 2 trials; risk difference -18.44, 95% CI -27.24 to -9.65, 481,807 participants, 4 trials), and procalcitonin-guided management (adjusted OR 0.10, 95% CI 0.07 to 0.14, 1008 participants, 2 trials) probably reduce antibiotic prescribing in general practice. We found moderate-quality evidence that procalcitonin-guided management probably reduces antibiotic prescribing in emergency departments (adjusted OR 0.34, 95% CI 0.28 to 0.43, 2605 participants, 7 trials). The overall effect of these interventions was small (few achieving greater than 50% reduction in antibiotic prescribing, most about a quarter or less), but likely to be clinically important.Compared to usual care, shared decision making probably makes little or no difference to reconsultation for the same illness (RR 0.87, 95% CI 0.74 to 1.03, 1860 participants, 4 trials, moderate-quality evidence), and may make little or no difference to patient satisfaction (RR 0.86, 95% CI 0.57 to 1.30, 1110 participants, 2 trials, low-quality evidence). Similarly, CRP testing probably has little or no effect on patient satisfaction (RR 0.79, 95% CI 0.57 to 1.08, 689 participants, 2 trials, moderate-quality evidence) or reconsultation (RR 1.08, 95% CI 0.93 to 1.27, 5132 participants, 4 trials, moderate-quality evidence). Procalcitonin-guided management probably results in little or no difference in treatment failure in general practice compared to normal care (adjusted OR 0.95, 95% CI 0.73 to 1.24, 1008 participants, 2 trials, moderate-quality evidence), however it probably reduces treatment failure in the emergency department compared to usual care (adjusted OR 0.76, 95% CI 0.61 to 0.95, 2605 participants, 7 trials, moderate-quality evidence).The quality of evidence for interventions focused on clinician educational materials and decision support in reducing antibiotic prescribing in general practice was either low or very low (no pooled result reported) and trial results were highly heterogeneous, therefore we were unable draw conclusions about the effects of these interventions. The use of rapid viral diagnostics in emergency departments may have little or no effect on antibiotic prescribing (RR 0.86, 95% CI 0.61 to 1.22, 891 participants, 3 trials, low-quality evidence) and may result in little to no difference in reconsultation (RR 0.86, 95% CI 0.59 to 1.25, 200 participants, 1 trial, low-quality evidence).None of the trials in the included reviews reported on management costs for the treatment of an ARI or any associated complications.

AUTHORS' CONCLUSIONS

We found evidence that CRP testing, shared decision making, and procalcitonin-guided management reduce antibiotic prescribing for patients with ARIs in primary care. These interventions may therefore reduce overall antibiotic consumption and consequently antibiotic resistance. There do not appear to be negative effects of these interventions on the outcomes of patient satisfaction and reconsultation, although there was limited measurement of these outcomes in the trials. This should be rectified in future trials.We could gather no information about the costs of management, and this along with the paucity of measurements meant that it was difficult to weigh the benefits and costs of implementing these interventions in practice.Most of this research was undertaken in high-income countries, and it may not generalise to other settings. The quality of evidence for the interventions of educational materials and tools for patients and clinicians was either low or very low, which prevented us from drawing any conclusions. High-quality trials are needed to further investigate these interventions.

Changing Nursing Practice in Survivorship Care With Clinical Decision Tools

The paradigm shift to include survivorship care as part of the cancer care continuum underscores the critical need for a change in nursing practice. One way to ensure that change in practice is delivered in a safe and efficient manner is through the use of clinical decision tools (CDTs). Such tools can be used to increase relevant knowledge and skills of nurses and patients. Despite the widespread recognition of their value, CDTs to educate providers on cancer survivors’ care are limited and, when available, often are not used. Clinical practice algorithms were developed for disease-specific survivorship clinics in a cancer academic center. This article reviews the conceptual framework of the survivorship algorithms, describes the application of the algorithms in multidisciplinary disease-specific survivorship clinics, and discusses the implementation strategies used to promote clinicians’ adoption and implementation of the algorithms. At a Glance • The authors found that algorithms can be successfully used as clinical decision tools(CDTs) to deliver survivorship care. • Algorithms and other CDTs are powerful tools to enhance professional practice. • Additional studies are needed to assess their effect on clinical practice and survivor outcomes.

Application of guidelines for aminoglycosides use in French hospitals in 2013-2014

In 2011, the French Agency for Safety of Health Products issued guidelines underlining the principles of proper aminoglycosides' use. The aim of the survey was to evaluate adherence to these guidelines two years after their issue. Characteristics of patients receiving aminoglycosides were recorded by voluntary facilities during a 3-month survey in 2013-2014. The modalities of aminoglycosides treatment were analysed by comparison with the French guidelines. A total of 3,323 patients were included by 176 facilities. Patients were mainly hospitalized in medical wards (33.0%), and treated for urinary-tract infections (24.7%). Compliance regarding the clinical indication and the daily aminoglycosides dose was observed in 65.2% and 62.9% of the cases, respectively. A 30-min once-daily IV administration was recorded in 62.5% of the cases. Aminoglycosides treatment duration was appropriate (≤5 days) for 93.6% of the patients. When considering the four criteria together, 23.2% of the patients had a treatment regimen aligned with the guidelines. Requests for measurements of peak and trough AG serum concentrations matched the guidelines in 24.9% and 67.4% of the cases, respectively. Two years after guidelines issue, aminoglycosides use remains unsatisfactory in French health-care facilities. Efforts should be made for guidelines promotion, especially regarding the issue of underdosing.

Antimicrobial Use Control Measures to Prevent and Control Antimicrobial Resistance in US Hospitals

Objective.

Clinical practice guidelines and recommended practices to control use of antibiotics have been published, but the effect of these practices on antimicrobial resistance (AMR) rates in hospitals is unknown. The objective of this study was to examine relationships between antimicrobial use control strategies and AMR rates in a national sample of US hospitals.

Design.

Cross-sectional, stratified study of a nationally representative sample of US hospitals.

Methods.

A survey instrument was sent to the person responsible for infection control at a sample of 670 US hospitals. The outcome was current prevalences of 4 epidemiologically important, drug-resistant pathogens, considered concurrently: methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci, ceftazidime-resistant Klebsiella species, and quinolone (ciprofloxacin)-resistant Escherichia coli Five independent variables regarding hospital practices were selected from the survey: the extent to which hospitals (1) implement practices recommended in clinical practice guidelines and ensure best practices for antimicrobial use, (2) disseminate information on clinical practice guidelines for antimicrobial use, (3) use antimicrobial-related information technology, (4) use decision support tools, and (5) communicate to prescribers about antimicrobial use. Control variables included the hospitals' number of beds, teaching status, Veterans Affairs status, geographic region, and number of long-term care beds; and the presence of an intensive care unit, a burn unit, or transplant services. A generalized estimating equation modeled all resistance rates simultaneously to identify overall predictors of AMR levels at the facility.

Results.

Completed survey instruments were returned by 448 hospitals (67%). Four antimicrobial control measures were associated with higher prevalence of AMR. Implementation of recommended practices for antimicrobial use (P< .01) and optimization of the duration of empirical antibiotic prophylaxis (P<.01) were associated with a lower prevalence of AMR. Use of restrictive formularies (P = .05) and dissemination of clinical practice guideline information (P<.01) were associated with higher prevalence of AMR. Number of beds and Veterans Affairs status were also associated with higher AMR rates overall.

Conclusions.

Implementation of guideline-recommended practices to control antimicrobial use and optimize the duration of empirical therapy appears to help control AMR rates in US hospitals. A longitudinal study would confirm the results of this cross-sectional study. These results highlight the need for systems interventions and reengineering to ensure more-consistent application of guideline-recommended measures for antimicrobial use.

Aminoglycoside use in a pediatric hospital: there is room for improvement-a before/after study

Aminoglycoside prescriptions were rarely evaluated in children care facilities. Because of risk of toxicity, these narrow spectrum antibiotics are commonly misused. In this study, we evaluate aminoglycoside prescription and assess the impact of an information campaign on modalities of prescription and monitoring practices in a pediatric hospital. This prospective study, before/after diffusion of local recommendations, has been conducted over 6 months. All computerized prescriptions were analyzed. A semi-passive diffusion of local recommendations to prescribers allowed researchers to differentiate between a pre-intervention (P1) and post-intervention period (P2). Endpoints were the improvement of administered doses (mg/kg), modalities of administration, treatment duration, indications, and the presence of pharmacological monitoring. Three hundred and ten prescriptions were analyzed (P1 = 163, P2 = 147). Most common sites of infection treated were as follows: joint-bone (33 %), urinary tract (17 %) and intra-abdominal (15 %). Among all prescriptions, respectively, 12 and 13 % were avoidable. Short-duration treatment and single daily dosing seem to be widely achieved, but despite an improvement between the two periods, 45 % of prescribed doses in P2 were still below our recommendations (77 % in P1).

CONCLUSION

The semi-passive diffusion of recommendations has not improved significantly medical practices. Active diffusion with a regular monitoring could be useful to improve the use of aminoglycosides.

WHAT IS KNOWN

• Misuse of aminoglycosides has been frequently described and evaluated in adult hospitals. • This misuse could be explained by their nephrotoxicity and their low therapeutic index. What is New: • Through this study, conducted in a pediatric hospital, we highlighted that practitioners misunderstand the aminoglycoside pharmacokinetic and pharmacodynamic targets and 12.3 % of aminoglycoside prescriptions could be avoided. • Finally, we showed that a semi-passive diffusion of local recommendations is not enough to improve aminoglycoside prescriptions.

Achieving change in primary care--effectiveness of strategies for improving implementation of complex interventions: systematic review of reviews

OBJECTIVE

To identify, summarise and synthesise available literature on the effectiveness of implementation strategies for optimising implementation of complex interventions in primary care.

DESIGN

Systematic review of reviews.

DATA SOURCES

MEDLINE, EMBASE, CINAHL, Cochrane Library and PsychINFO were searched, from first publication until December 2013; the bibliographies of relevant articles were screened for additional reports.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Eligible reviews had to (1) examine effectiveness of single or multifaceted implementation strategies, (2) measure health professional practice or process outcomes and (3) include studies from predominantly primary care in developed countries. Two reviewers independently screened titles/abstracts and full-text articles of potentially eligible reviews for inclusion.

DATA SYNTHESIS

Extracted data were synthesised using a narrative approach.

RESULTS

91 reviews were included. The most commonly evaluated strategies were those targeted at the level of individual professionals, rather than those targeting organisations or context. These strategies (eg, audit and feedback, educational meetings, educational outreach, reminders) on their own demonstrated a small to modest improvement (2-9%) in professional practice or behaviour with considerable variability in the observed effects. The effects of multifaceted strategies targeted at professionals were mixed and not necessarily more effective than single strategies alone. There was relatively little review evidence on implementation strategies at the levels of organisation and wider context. Evidence on cost-effectiveness was limited and data on costs of different strategies were scarce and/or of low quality.

CONCLUSIONS

There is a substantial literature on implementation strategies aimed at changing professional practices or behaviour. It remains unclear which implementation strategies are more likely to be effective than others and under what conditions. Future research should focus on identifying and assessing the effectiveness of strategies targeted at the wider context and organisational levels and examining the costs and cost-effectiveness of implementation strategies.

The effectiveness of knowledge translation interventions for promoting evidence-informed decision-making among nurses in tertiary care: a systematic review and meta-analysis

BACKGROUND

Nurses are increasingly expected to engage in evidence-informed decision-making (EIDM) to improve client and system outcomes. Despite an improved awareness about EIDM, there is a lack of use of research evidence and understanding about the effectiveness of interventions to promote EIDM. This project aimed to discover if knowledge translation (KT) interventions directed to nurses in tertiary care are effective for improving EIDM knowledge, skills, behaviours, and, as a result, client outcomes. It also sought to understand contextual factors that affect the impact of such interventions.

METHODS

A systematic review funded by the Canadian Institutes of Health Research (PROSPERO registration: CRD42013003319) was conducted. Included studies examined the implementation of any KT intervention involving nurses in tertiary care to promote EIDM knowledge, skills, behaviours, and client outcomes or studies that examined contextual factors. Study designs included systematic reviews, quantitative, qualitative, and mixed method studies. The search included electronic databases and manual searching of published and unpublished literature to November 2012; key databases included MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Excerpta Medica (EMBASE). Two reviewers independently performed study selection, risk of bias assessment, and data extraction. Studies with quantitative data determined to be clinically homogeneous were synthesized using meta-analytic methods. Studies with quantitative data not appropriate for meta-analysis were synthesized narratively by outcome. Studies with qualitative data were synthesized by theme.

RESULTS

Of the 44,648 citations screened, 30 citations met the inclusion criteria (18 quantitative, 10 qualitative, and 2 mixed methods studies). The quality of studies with quantitative data ranged from very low to high, and quality criteria was generally met for studies with qualitative data. No studies evaluated the impact on knowledge and skills; they primarily investigated the effectiveness of multifaceted KT strategies for promoting EIDM behaviours and improving client outcomes. Almost all studies included an educational component. A meta-analysis of two studies determined that a multifaceted intervention (educational meetings and use of a mentor) did not increase engagement in a range of EIDM behaviours [mean difference 2.7, 95 % CI (-1.7 to 7.1), I (2) = 0 %]. Among the remaining studies, no definitive conclusions could be made about the relative effectiveness of the KT interventions due to variation of interventions and outcomes, as well as study limitations. Findings from studies with qualitative data identified the organizational, individual, and interpersonal factors, as well as characteristics of the innovation, that influence the success of implementation.

CONCLUSIONS

KT interventions are being implemented and evaluated on nurses' behaviour and client outcomes. This systematic review may inform the selection of KT interventions and outcomes among nurses in tertiary care and decisions about further research.

Hand Hygiene Practices After Brief Encounters With Patients: An Important Opportunity for Prevention

Objective.

To identify characteristics of encounters between healthcare workers (HCWs) and patients that correlated with hand hygiene adherence among HCWs.

Design.

Observational study.

Setting.

Intensive care unit in a Veterans Affairs hospital.

Participants.

HCWs.

Results.

There were 767 patient encounters observed (48.6% involved nurses, 20.6% involved physicians, and 30.8% involved other HCWs); 39.8% of encounters involved patients placed under contact precautions. HCW contact with either the patient or surfaces in the patient's environment occurred during all encounters; direct patient contact occurred during 439 encounters (57.4%), and contact with environmental surfaces occurred during 710 encounters (92.6%). The median duration of encounters was 2 minutes (range, <1 to 51 minutes); 33.6% of encounters lasted 1 minute or less, with no significant occupation-associated differences in the median duration of encounters. Adherence with hand hygiene practices was correlated with the duration of the encounter, with overall adherences of 30.0% after encounters of ≤1 minute, 43.4% after encounters of >1 to ≤2 minutes, 51.1% after encounters of >3 to ≤5 minutes, and 64.9% after encounters of >5 minutes (P < .001 by the x2 for trend). In multivariate analyses, longer encounter duration, contact precautions status, patient contact, and nursing occupation were independently associated with adherence to hand hygiene recommendations.

Conclusions.

In this study, adherence to hand hygiene practices was lowest after brief patient encounters (ie, <2 minutes). Brief encounters accounted for a substantial proportion of all observed encounters, and opportunities for hand contamination occurred during all brief encounters. Therefore, improving adherence after brief encounters may have an important overall impact on the transmission of healthcare-associated pathogens and may deserve special emphasis in the design of programs to promote adherence to hand hygiene practices.

Effect of a drug allergy educational program and antibiotic prescribing guideline on inpatient clinical providers' antibiotic prescribing knowledge

BACKGROUND

Inpatient providers have varying levels of knowledge in managing patients with drug and/or penicillin (PCN) allergy.

OBJECTIVES

Our objectives were (1) to survey inpatient providers to ascertain their baseline drug allergy knowledge and preparedness in caring for patients with PCN allergy, and (2) to assess the impact of an educational program paired with the implementation of a hospital-based clinical guideline.

METHODS

We electronically surveyed 521 inpatient providers at a tertiary care medical center at baseline and again 6 weeks after an educational initiative paired with clinical guideline implementation. The guideline informed providers on drug allergy history taking and antibiotic prescribing for inpatients with PCN or cephalosporin allergy.

RESULTS

Of 323 unique responders, 42% (95% CI, 37-48%) reported no prior education in drug allergy. When considering those who responded to both surveys (n = 213), we observed a significant increase in knowledge about PCN skin testing (35% vs 54%; P < .001) and loss of PCN allergy over time (54% vs 80%; P < .0001). Among those who reported attending an educational session (n = 62), preparedness to determine if an allergy was severe significantly improved (77% vs 92%; P = .03). Other areas, including understanding absolute contraindications to receiving a drug again and PCN cross-reactivity with other antimicrobials, did not improve significantly.

CONCLUSIONS

Inpatient providers have drug allergy knowledge deficits but are interested in tools to help them care for inpatients with drug allergies. Our educational initiative and hospital guideline implementation were associated with increased PCN allergy knowledge in several crucial areas. To improve care of inpatients with drug allergy, more research is needed to evaluate hospital policies and sustainable educational tools.

Effectiveness of physician-targeted interventions to improve antibiotic use for respiratory tract infections

BACKGROUND

Antibiotic use and concomitant resistance are increasing. Literature reviews do not unambiguously indicate which interventions are most effective in improving antibiotic prescribing practice.

AIM

To assess the effectiveness of physician-targeted interventions aiming to improve antibiotic prescribing for respiratory tract infections (RTIs) in primary care, and to identify intervention features mostly contributing to intervention success.

DESIGN AND SETTING

Analysis of a set of physician-targeted interventions in primary care.

METHOD

A literature search (1990-2009) for studies describing the effectiveness of interventions aiming to optimise antibiotic prescription for RTIs by primary care physicians. Intervention features were extracted and effectiveness sizes were calculated. Association between intervention features and intervention success was analysed in multivariate regression analysis.

RESULTS

This study included 58 studies, describing 87 interventions of which 60% significantly improved antibiotic prescribing; interventions aiming to decrease overall antibiotic prescription were more frequently effective than interventions aiming to increase first choice prescription. On average, antibiotic prescription was reduced by 11.6%, and first choice prescription increased by 9.6%. Multiple interventions containing at least 'educational material for the physician' were most often effective. No significant added value was found for interventions containing patient-directed elements. Communication skills training and near-patient testing sorted the largest intervention effects.

CONCLUSION

This review emphasises the importance of physician education in optimising antibiotic use. Further research should focus on how to provide physicians with the relevant knowledge and tools, and when to supplement education with additional intervention elements. Feasibility should be included in this process.

Audit and feedback of antibiotic use: utilising electronic prescription data

BACKGROUND

There is now little doubt that improving antimicrobial use is necessary for the containment of resistance.

OBJECTIVE

To determine whether providing individualised feedback to doctors about their recent compliance with the hospital's antibiotic policy improves compliance with the policy.

METHODS

This study was conducted at a teaching hospital in Sydney, Australia. Computerised alerts integrated into the electronic prescribing system (ePS) inform prescribers of the local antibiotic policy. We utilised prescribing data extracted from the ePS for 'audit and feedback'. Thirty-six prescribers were sent feedback letters via email. We also interviewed doctors who had received letters to explore their views of the feedback and the policy in general.

RESULTS

There was no significant change in compliance with the policy following implementation of the feedback intervention (0% compliant vs 11.9%; p = 0.07). Several problems with the policy and the approval process were identified by researchers during auditing and by prescribers during interviews. Some problems identified made it difficult to accurately assess compliance and for doctors to comply with the policy.

CONCLUSION

Our intervention did not result in improved compliance with the antibiotic policy but revealed practical problems with the policy and approval process that had not been identified prior to the trial. Greater support for the policy by senior doctors and the assignment of more clearly defined roles and responsibilities associated with antibiotic use and approval may result in improved compliance. Harnessing the full potential of technology would streamline the antimicrobial approval process and allow more efficient and reliable monitoring of antibiotic use and compliance. Many of the problems we identified are generic issues of importance to all organisations seeking to integrate antimicrobial stewardship into ePS.

Impact of guideline implementation on transfusion practices in a surgical intensive care unit

BACKGROUND

Anemia is a common clinical problem in cardiac surgery patients in the postoperative period and may result in transfusion in up to 90% of this population. There is tremendous variation in transfusion rates by hospital and individual physician. It is unknown if implementation of a clinical practice guideline lowers unnecessary transfusion in hospital practices that already have a restrictive transfusion culture .

OBJECTIVE

To evaluate transfusion practice before and after implementation of a clinical practice guideline.

DESIGN

Pre/post intervention study.

SETTING

Sixteen bed surgical intensive care unit in an academic hospital.

PARTICIPANTS

Four hundred ninety-five adult patients undergoing cardiac surgery.

INTERVENTIONS

Implementation of an anemia clinical practice guideline reinforced with education and retrospective audit/feedback.

MEASUREMENTS AND MAIN RESULTS

A total of 252 pre-intervention and 243 postintervention cases were examined. Unnecessary transfusion occurred in 14.7% of pre-intervention patients and decreased to a rate of 8.1% after guideline implementation (p = 0.016).

CONCLUSIONS

This study suggests that clinical guideline implementation utilizing guideline development, education, and compliance audit/feedback may reduce unnecessary transfusion in cardiac surgery patients. A fully powered prospective trial would be necessary to validate these findings.

Antimicrobial prescribing in European nursing homes

OBJECTIVES

The aim of this study was to investigate antimicrobial prescribing in nursing homes in countries across Europe.

METHODS

Point prevalence studies were completed in April and November 2009 in 85 nursing homes in 15 European countries and two UK administrations.

RESULTS

A total of 10,388 and 9430 residents participated in April and November 2009, respectively. The mean prevalence of antimicrobial prescribing in the nursing homes was 6.5% in April and 5.0% in November. The most commonly prescribed antimicrobials were methenamine (17.5%), trimethoprim (11.4%) and co-amoxiclav (11.1%) in April and co-amoxiclav (12.2%), nitrofurantoin (12.2%) and methenamine (11.5%) in November. There was large variation in the overall mean antimicrobial prescribing in the selected nursing homes from each of the contributing countries, ranging from 1.4% in Germany and Latvia to 19.4% in Northern Ireland in April and 1.2% in Latvia to 13.4% in Finland in November. Furthermore, differences in prescribing were apparent within countries with the largest variation evident in nursing homes in Northern Ireland (21.5%) in April and Finland in November (30.1%).

CONCLUSIONS

This is the first study to investigate antimicrobial prescribing in nursing homes in a large number of European countries. The findings suggest that there is considerable variation in antimicrobial prescribing in nursing homes across and within European countries. Nursing homes provide a significant service to the European community and must be supported in order to optimize antimicrobial use and limit the development of antimicrobial resistance.

Does the clinical practice guideline on Parkinson's disease change health outcomes? A cluster randomized controlled trial

The successful transfer of clinical practice guidelines (CPGs) into patient care depends on the appropriateness of the implementation method. This study strived for a better understanding of which intervention strategy is effective in implementing the CPG on Parkinson's disease (CPG-PD). In a cluster randomized controlled trial, we compared the impact of two different implementation strategies of the CPG-PD on health outcomes of PD patients. The primary outcome of health-related quality of life was measured by PDQ-39. The neurologists of the intervention group (IG) versus a control group (CG) received the CPG-PD with special instructions, a 4-h training and were offered personal feedback. Patients were followed over three assessment times: baseline, post-test (6 months) and follow-up (9 months). Lack of time and remuneration resulted in low study participation (32 out of 619 contacted neurologists). Multilevel modelling revealed that primary (PDQ-39) and secondary efficacy variables (EQ-5D, CGI, HADS-D, ZUF-8) of 386 patients were not affected significantly by the intervention and failed to show any significant difference between the two groups. The EQ-5D VAS scale (p = 0.0288) and the CGI-P severity scale (p = 0.0072) showed a significant worsening over time. A significant decrease of hours of dyskinesias in the IG (p = 0.007) was observed, whereas Parkinson symptoms did not change significantly between the groups. Lacking awareness of the CPG-PD seems to be no longer a barrier for its use, but it is still a major challenge to find effective implementation methods to optimise clinical outcome. Further studies are needed for a more comprehensive understanding of successful implementation strategies.

Interventions in health care professionals to improve treatment in children with upper respiratory tract infections

OBJECTIVE

To analyse which strategies are used to promote evidence based interventions in the management of children with upper respiratory tract infections (URTIs) in daily practice. To assess the effectiveness of these interventions, and when more are effective--which works best. And to analyse the costs associated with these interventions.

METHODS

We systematically searched Pubmed, Embase and CENTRAL bibliographies for studies on the effectiveness of strategies aimed at changing health care professionals' behavior in the management of children with URTIs.

RESULTS

The search yielded 11,788 references, of which 18 studies were eligible, and 10 met the inclusion criteria. Most strategies were aimed at changing antibiotic prescribing behavior in children with acute otitis media. All strategies used (i.e. computer interventions, educational sessions with or without education materials, collaborative development of guidelines and a training video in combination with a risk factor checklist) were effective in changing health care professionals practice regarding children with URTIs. Multifaceted and computer strategies work best. Computer interventions reduced antibiotic prescribing by 4% and 34% and increased guideline compliance by 41%. Educational sessions combined with education materials reduced inappropriate antibiotic prescription by 2% and 17% and increased knowledge of compliance enhancing strategies by 28% and 29%. Collaborative guideline development combined with educational materials reduced inappropriate antibiotic prescription by 24% and 40%. Finally, by a combination of a training video and a risk factor checklist appropriate referrals by the GP to the otolaryngologist increased by 37%. Since the costs associated with the interventions were not explicitly mentioned in the articles, no conclusion on cost-effectiveness can be drawn.

CONCLUSION

Multifaceted and computer strategies appear to be most effective to put evidence into practice in the area of URTIs in children.

Are interventions for improving the quality of services provided by specialized drug shops effective in sub-Saharan Africa? A systematic review of the literature

PURPOSE

We set out to determine effectiveness of interventions for improving the quality of services provided by specialized drug shops in sub-Saharan Africa.

DATA SOURCES

We searched PubMed, CAB Abstracts, Web of Science, PsycINFO and Eldis databases and websites for organizations such as WHO and Management Sciences for Health. Finally, we searched manually through the references of retrieved articles.

STUDY SELECTION

Our search strategy included randomized trials, time-series studies and before and after studies evaluating six interventions; education, peer review, reorganizing administrative structures, incentives, regulation and legislation.

DATA EXTRACTION

We extracted information on design features, participants, interventions and outcomes assessed studies for methodological quality, and extracted results, all using uniform checklists.

RESULTS OF DATA SYNTHESIS

We obtained 10 studies, all implementing educational interventions. Outcome measures were heterogeneous and included knowledge, communication and dispensing practices. Education improved knowledge across studies, but gave mixed results on communication between sellers and clients, dispensing of appropriate treatments and referring of patients to health facilities. Profit incentives appeared to constrain behaviour change in certain instances, although cases of shops adopting practices at the expense of sales revenue were also reported.

CONCLUSION

Evidence suggests that knowledge and practices of pharmacies and drug shops can be improved across a range of diseases and countries/regions, although variations were reported across studies. Profit incentives appear to bear some influence on the level of success of interventions. More work is required to extend the geographical base of evidence, investigate cost-effectiveness and evaluate sustainability of interventions over periods longer than 1 year.

Implementation of treatment guidelines to support judicious use of antibiotic therapy

BACKGROUND AND OBJECTIVE

Judicious use of antibiotics is essential considering the growth of antimicrobial resistance and escalating costs in health care. This intervention study used treatment guidelines to improve antibiotic therapy by changing prescribing practice.

METHODS

A before-after intervention study was performed in a 550-bed tertiary care teaching hospital in Switzerland, with an additional follow-up analysis 1 year later. The pre-intervention phase included chart analysis of current antibiotic use in 100 consecutive patients from the representative medical and surgical wards included in the study. Treatment guidelines were defined, taking into account published guidelines, the local antibacterial sensitivity of the pathogens, and the hospital antibiotic formulary defined by the drug and therapeutics committee. The guidelines were presented to the medical residents on a pocket card. They were informed and educated by the pharmacist (intervention). In the post-intervention phase immediately after the instruction, and in the follow-up phase 1 year later, a prospective analysis of antibiotic prescription was performed by chart review of 100 antibacterial treatments in consecutive patients to detect changes in antibiotic prescribing (treatment) and to determine whether these changes were sustained.

RESULTS

The pre-intervention review of antibiotic use showed the need for therapy improvements in urinary tract infections (UTI) and hospital-acquired pneumonia (HAP). In the post-intervention phase 100% of UTI were treated as recommended, compared to 30% before the intervention (P < 0.001). The follow-up analysis showed a decrease in guideline adherence to 39% in patients with UTI. Before implementation of the clinical guidelines, HAP was inappropriately treated like community-acquired pneumonia (CAP). Immediately after the intervention, 50% of HAP patients were treated as recommended, and 1 year later (follow-up phase) 56% of HAP patients received the recommended antibiotic medication. This change in prescription practice was significant (P < 0.05).

CONCLUSION

Antibiotic treatment guidelines for the infections most commonly occurring in hospitalized patients resulted in a significant increase in appropriate antibiotic use. The program was successful in changing prescription practice and achieved a sustained optimization of HAP therapy. Implementing, teaching and monitoring treatment guidelines can have a major impact on patient care.

A systematic review of techniques and interventions for improving adherence to inclusion and exclusion criteria during enrolment into randomised controlled trials

Background

Enrolment of patients into a randomised controlled trial (RCT) in violation of key inclusion or exclusion criteria, may lead to excess avoidable harm. The purpose of this paper was to systematically identify and review techniques and interventions proven to prevent or avoid inappropriate enrolment of patients into RCTs.

Methods

EMBASE, MEDLINE, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, online abstract repositories, and conference websites were searched. Experts were contacted and bibliographies of retrieved papers hand-searched. The search cut-off date was 31 August 2009.

Results

No primary publications were found. We identified one study in the grey literature (conference abstracts and presentations) reporting the results of an evaluation of the effectiveness of an intervention designed to prevent or avoid inappropriate enrolment of patients into an RCT. In the context of a multicentre trial, use of a dummy enrolment run-in phase was shown to reduce enrolment errors significantly (P < 0.001), from 16.1% during the run-in phase to < 1% after trial initiation.

Conclusions

Our systematic search yielded only one technique or intervention shown to improve adherence to eligibility criteria during enrolment into RCTs. Given the potential harm involved in recruiting patients into a clinical trial in violation of key eligibility criteria, future research is needed to better inform those conducting clinical trials of how best to prevent enrolment errors

Factors influencing the implementation of clinical guidelines for health care professionals: a systematic meta-review

BACKGROUND

Nowadays more and more clinical guidelines for health care professionals are being developed. However, this does not automatically mean that these guidelines are actually implemented. The aim of this meta-review is twofold: firstly, to gain a better understanding of which factors affect the implementation of guidelines, and secondly, to provide insight into the "state-of-the-art" regarding research within this field.

METHODS

A search of five literature databases and one website was performed to find relevant existing systematic reviews or meta-reviews. Subsequently, a two-step inclusion process was conducted: (1) screening on the basis of references and abstracts and (2) screening based on full-text papers. After that, relevant data from the included reviews were extracted and the methodological quality of the reviews was assessed by using the Quality Assessment Checklist for Reviews.

RESULTS

Twelve systematic reviews met our inclusion criteria. No previous systematic meta-reviews meeting all our inclusion criteria were found. Two of the twelve reviews scored high on the checklist used, indicating only "minimal" or "minor flaws". The other ten reviews scored in the lowest of middle ranges, indicating "extensive" or "major" flaws. A substantial proportion (although not all) of the reviews indicates that effective strategies often have multiple components and that the use of one single strategy, such as reminders only or an educational intervention, is less effective. Besides, characteristics of the guidelines themselves affect actual use. For instance, guidelines that are easy to understand, can easily be tried out, and do not require specific resources, have a greater chance of implementation. In addition, characteristics of professionals - e.g., awareness of the existence of the guideline and familiarity with its content - likewise affect implementation. Furthermore, patient characteristics appear to exert influence: for instance, co-morbidity reduces the chance that guidelines are followed. Finally, environmental characteristics may influence guideline implementation. For example, a lack of support from peers or superiors, as well as insufficient staff and time, appear to be the main impediments.

CONCLUSION

Existing reviews describe various factors that influence whether guidelines are actually used. However, the evidence base is still thin, and future sound research - for instance comparing combinations of implementation strategies versus single strategies - is needed.

Improving antibiotic selection: a systematic review and quantitative analysis of quality improvement strategies

OBJECTIVE

We sought to assess which interventions are most effective at improving the prescribing of recommended antibiotics for acute outpatient infections.

DESIGN AND METHODS

We undertook a systematic review with quantitative analysis of the Cochrane Registry Effective Practice and Organization of Care (EPOC) database, supplemented by MEDLINE and hand-searches. Inclusion criteria included clinical trials with contemporaneous or strict historical controls that reported data on antibiotic selection in acute outpatient infections. The effect size of studies with different intervention types were compared using nonparametric statistics. To maximize comparability between studies, quantitative analysis was restricted to studies that reported absolute changes in the amount of or percent compliance with recommended antibiotic prescribing.

RESULTS

Twenty-six studies reporting 33 trials met inclusion criteria. Most interventions used clinician education alone or in combination with audit and feedback. Among the 22 comparisons amenable to quantitative analysis, recommended antibiotic prescribing improved by a median of 10.6% (interquartile range [IQR] 3.4-18.2%). Trials evaluating clinician education alone reported larger effects than interventions combining clinician education with audit and feedback (median effect size 13.9% [IQR 8.6-21.6%] vs. 3.4% [IQR 1.8-9.7%], P = 0.03). This result was confounded by trial sample size, as trials having a smaller number of participating clinicians reported larger effects and were more likely to use clinician education alone. Active forms of education, sustained interventions, and other features traditionally associated with successful quality improvement interventions were not associated with effect size and showed no evidence of confounding the association between clinician education-only strategies and outcome.

CONCLUSIONS

Multidimensional interventions using audit and feedback to improve antibiotic selection were less effective than interventions using clinician education alone. Although confounding may partially account for this finding, our results suggest that enhancing the intensity of a focused intervention may be preferable to a less intense, multidimensional approach.

Antimicrobial stewardship

Antimicrobial stewardship is a key component of a multifaceted approach to preventing emergence of antimicrobial resistance. Good antimicrobial stewardship involves selecting an appropriate drug and optimizing its dose and duration to cure an infection while minimizing toxicity and conditions for selection of resistant bacterial strains. Studies conducted over the years indicate that antibiotic use is unnecessary or inappropriate in as many as 50% of cases in the United States, and this creates unnecessary pressure for the selection of resistant species. Because the pharmaceutical industry pipeline for new antibiotics has been curtailed in recent years, and it may be > or = 10 years before important new antibiotics to treat certain resistant bacteria find their way to market, a premium has been set on maintaining the effectiveness of currently available agents. Several strategies, including prescriber education, formulary restriction, prior approval, streamlining, antibiotic cycling, and computer-assisted programs have been proposed to improve antibiotic use. Although rigorous clinical data in support of these strategies are lacking, the most effective means of improving antimicrobial stewardship will most likely involve a comprehensive program that incorporates multiple strategies and collaboration among various specialties within a given healthcare institution. Computer-assisted software programs may be especially useful in implementing these comprehensive programs. The antimicrobial stewardship program at the Hospital of the University of Pennsylvania, which has been shown to improve appropriateness of antibiotic use and cure rates, decrease failure rates, and reduce healthcare-related costs, is used as an example in support of this multifaceted, multidisciplinary approach. At this time, data from well-controlled studies examining the effect of antibacterial stewardship on emergence of resistance are limited, but available data suggest that good antibiotic stewardship reduces rates of Clostridium difficile-associated diarrhea, resistant gram-negative bacilli, and vancomycin-resistant enterococci.

Exploring obstacles to proper timing of prophylactic antibiotics for surgical site infections

BACKGROUND

Surgical site infections remain one of the leading types of nosocomial infections. The administration of prophylactic antibiotics within a specific interval has been shown to reduce the burden of surgical site infections, but adherence to proper timing guidelines remains problematic. This study examined perceived obstacles to the use of evidence-based guidelines for the timely administration of prophylactic antibiotics to prevent surgical site infections.

METHODS

27 semi-structured interviews were conducted with anesthesiologists (n = 12), surgeons (n = 11), and perioperative administrators (n = 4) in two large academic hospitals to elicit their perceptions of the factors that prevent the timely administration of prophylactic antibiotics. Using a grounded theory approach, transcripts were analyzed for recurrent themes.

RESULTS

Despite having knowledge of guidelines, participants perceived consistent failure in the proper timing of antibiotic administration. Thematic analysis revealed a number of obstacles to the observance of guidelines including: (1) low priority, (2) inconvenience, (3) workflow, (4) organizational communication, and (5) role perception. Workflow and role perception were the dominant obstacles.

CONCLUSION

This study suggests that proper antibiotic timing is thwarted by significant obstacles. The gap between evidence-based guidelines and practice is populated by individual values, professional conflicts, and organizational conflicts which must be addressed in order to achieve optimal practice in this domain. Using group interviews to reveal these factors to team members and managers may be a first step to resolving the gap and reducing surgical site infections.

Reduction of broad-spectrum antibiotic use with computerized decision support in an intensive care unit

OBJECTIVE

To implement and evaluate the effect of a computerized decision support tool on antibiotic use in an intensive care unit (ICU).

DESIGN

Prospective before-and-after cohort study.

SETTING

Twenty-four bed tertiary hospital adult medical/surgical ICU.

PARTICIPANTS

All consecutive patients from May 2001 to November 2001 (N = 524) and March 2002 to September 2002 (N = 536).

INTERVENTION

A real-time microbiology browser and computerized decision support system for isolate directed antibiotic prescription.

MAIN OUTCOME MEASURES

Number of courses of antibiotic prescribed, antibiotic utilization (defined daily doses (DDDs)/100 ICU bed-days), antibiotic susceptibility mismatches, and system uptake.

RESULTS

There was a significant reduction in the proportion of patients prescribed carbapenems [odds ratio (OR) = 0.61, 95% confidence interval (CI) = 0.39-0.97, P = 0.04], third-generation cephalosporins (OR = 0.58, 95% CI = 0.42-0.79, P = 0.001), and vancomycin (OR = 0.67, 95% CI = 0.45-1.00, P = 0.05) after adjustment for risk factors including Apache II score, suspected infection, positive microbiology, intubation, and length of stay. The decision support tool was associated with a 10.5% reduction in both total antibiotic utilization (166-149 DDDs/100 ICU bed days) and the highest volume broad-spectrum antibiotics. There were fewer susceptibility mismatches for initial antibiotic therapy (OR = 0.63, 95% CI = 0.39-0.98, P = 0.02) and increased de-escalation to narrower spectrum antibiotics. Uptake of the program was high with 6028 access episodes during the 6-month evaluation period.

CONCLUSIONS

This tool streamlined collation and clinical use of microbiology results and integrated into the daily ICU workflow. Its introduction was accompanied by a reduction in both total and broad-spectrum antibiotic use and an increase in the number of switches to narrower spectrum antibiotics.

Antimicrobial stewardship programs in health care systems

Antimicrobial stewardship programs in hospitals seek to optimize antimicrobial prescribing in order to improve individual patient care as well as reduce hospital costs and slow the spread of antimicrobial resistance. With antimicrobial resistance on the rise worldwide and few new agents in development, antimicrobial stewardship programs are more important than ever in ensuring the continued efficacy of available antimicrobials. The design of antimicrobial management programs should be based on the best current understanding of the relationship between antimicrobial use and resistance. Such programs should be administered by multidisciplinary teams composed of infectious diseases physicians, clinical pharmacists, clinical microbiologists, and infection control practitioners and should be actively supported by hospital administrators. Strategies for changing antimicrobial prescribing behavior include education of prescribers regarding proper antimicrobial usage, creation of an antimicrobial formulary with restricted prescribing of targeted agents, and review of antimicrobial prescribing with feedback to prescribers. Clinical computer systems can aid in the implementation of each of these strategies, especially as expert systems able to provide patient-specific data and suggestions at the point of care. Antibiotic rotation strategies control the prescribing process by scheduled changes of antimicrobial classes used for empirical therapy. When instituting an antimicrobial stewardship program, a hospital should tailor its choice of strategies to its needs and available resources.

Effectiveness of a multiple intervention to reduce antibiotic prescribing for respiratory tract symptoms in primary care: randomised controlled trial

OBJECTIVES

To assess the effectiveness of a multiple intervention aimed at reducing antibiotic prescription rates for symptoms of the respiratory tract in primary care.

DESIGN

Randomised controlled trial.

SUBJECTS

Twelve peer review groups including 100 general practitioners with their collaborating pharmacists in the region of Utrecht, Netherlands.

INTERVENTION

The intervention consisted of group education meetings, with a consensus procedure on indication for and type of antibiotics and with training in communication skills; monitoring and feedback on prescribing behaviour; group education for assistants of general practitioners and pharmacists; and education material for patients. The control group did not receive any of these elements.

MAIN OUTCOME MEASURES

Antibiotic prescription rates for acute symptoms of the respiratory tract and patients' satisfaction.

RESULTS

89 general practitioners completed the study (89%). At baseline, prescription rates for antibiotics for respiratory tract symptoms did not differ between intervention and control group (27% v 29%, respectively). After nine months, the prescription rates in the intervention group fell to 23%, whereas the control group's rose to 37% (mean difference in change -12%, 95% confidence interval -18.9% to -4.0%). Multilevel analysis confirmed the results of the unadjusted analysis (intervention effect -10.7%, -20.3% to -1.0%). Patients' satisfaction was high and did not differ in the two groups at baseline or after the intervention.

CONCLUSIONS

A multiple intervention reduced prescribing rates of antibiotics for respiratory tract symptoms while maintaining a high degree of satisfaction among patients. Further research should focus on the sustainability and cost effectiveness of this intervention.

Optimizing antibiotic prescribing for acute cough in general practice: a cluster-randomized controlled trial

OBJECTIVES

To assess the effect of a tailored professional intervention, including academic detailing, on antibiotic prescribing for acute cough.

METHODS

In a cluster-randomized controlled before and after study 85 Flemish GPs included adult patients with acute cough consulting in the periods February-April 2000 and 2001. The intervention consisted of a clinical practice guideline for acute cough, an educational outreach visit and a postal reminder to support its implementation in January 2001. Antibiotic prescribing rates and patients' symptom resolution were the main outcome measures.

RESULTS

Thirty-six of 42 GPs received the intervention and 35 of 43 GPs served as controls; 1503 patients were eligible for analysis. Only in the intervention group were patients less likely to receive antibiotics after the intervention [OR(adj) (95% CI)=0.56 (0.36-0.87)]. Prescribed antibiotics were also more in line with the guideline in the intervention group [1.90 (0.96-3.75)] and less expensive from the perspective of the National Sickness and Invalidity Insurance Institute [MD(adj) (95% CI)= Euro -6.89 [-11.77-(-2.02)]]. No significant differences were found between the groups for the time to symptom resolution.

CONCLUSIONS

An (inter)actively delivered tailored intervention implementing a guideline for acute cough is successful in optimizing antibiotic prescribing without affecting patients' symptom resolution. Further research efforts should be devoted to cost-effectiveness studies of such interventions.

Trends in antimicrobial prescribing for bronchitis and upper respiratory infections among adults and children

OBJECTIVES

This study examined antimicrobial prescribing patterns for adults and children with bronchitis or upper respiratory infections (URIs) before and after release of nationally disseminated pediatric practice recommendations.

METHODS

Data from the 1993, 1995, 1997, and 1999 National Ambulatory Medical Care Survey were used to evaluate prescriptions for antimicrobials for URIs and bronchitis.

RESULTS

From 1993 to 1999, the proportion of children receiving antimicrobials after visits for URIs and bronchitis decreased. However, the use of broad-spectrum antimicrobials rose from 10.6% of bronchitis visits to 40.5%. Prescriptions of antimicrobials for adults with URIs or bronchitis showed a decrease between 1993 and 1999.

CONCLUSIONS

Although antimicrobial prescribing for URIs and bronchitis has decreased for both children and adults, the prescribing of broad-spectrum antibiotics among children has shown a proportional rise.

Mutual influences of general practitioners in partnerships

The aim of this study was to find out whether or not general practitioners (GPs) within the same partnership show more similarities in attitudes and behaviour than GPs in different partnerships, and what the causes of these similarities might be. Knowledge of the causes of patterns of similarities within medical teams contributes to understanding medical practice variation, which is crucial in developing effective health care policies. Data were used from the Dutch National Survey of General Practice ('87/'88), consisting of a stratified sample of 161 Dutch GPs, who served 335,000 patients in total. To find out whether GPs in the same partnership are indeed more similar than GPs randomly chosen from different partnerships, we constructed two kinds of pairs: all possible pairs of GPs working in the same partnership (actual pairs), and randomly constructed pairs of GPs who are not working in the same partnership (random pairs). For each pair difference scores were computed for a variety of attitudes and behaviour. Difference scores for actual and random pairs were analysed using multi-level analysis. Most differences in attitudes and behaviour were smaller for actual pairs than for random pairs. Furthermore, in the majority of the cases differences were no longer statistically significant after explanatory variables indicating selection, gradual adaptation and rapid adaptation through shared circumstances were taken into account. It was found that Dutch GPs working in the same partnership showed more resemblance in attitudes and behaviour than GPs not working in the same partnership. Most indications point towards circumstances, and to a lesser extent towards adaptation, as an explanation of similarities within partnerships. The implication of this study is that medical practice variations are not merely individual differences in preferred practice style, but are patterned by social processes in partnerships and local circumstances.

Compliance with instructions for writing structured care management tools

The aim of this study was to assess whether clinical guidelines complied with the instructions for writing structured care management tools in a French university hospital. A cross-sectional study of guidelines for appropriate antimicrobial agent use in the authors' institution was carried out. A total of 221 guidelines were retrieved in 62 hospital units. The number of guidelines by unit ranged from one to 22 and 198 guidelines (90 per cent) had been developed at the local level. None of the guidelines fully complied with the ten criteria of the instructions. Each guideline met, on average, 4.2 criteria (3.9-4.5). The partial compliance rate was 75 per cent (68-80). In two-level multivariate analysis, factors associated with partial compliance were: dissemination of guidelines after implementation of the instructions (odds ratio = 6.25 (2.41-16.21)), existence of more than one storage site for guidelines in each unit (OR = 3.26 (1.03-10.32)), and hospital unit (variance of the intercept = 1.54).
