Implementing practice guidelines: a workshop on guidelines dissemination and implementation with a focus on asthma and COPD

Ensuring equitable access to guideline-based asthma care across the lifespan: Tips and future directions to the successful implementation of the new NAEPP 2020 guidelines, a Work Group Report of the AAAAI Asthma, Cough, Diagnosis, and Treatment Committee

The most recent recommendations from the 2020 National Asthma Education and Prevention Program Update and Global Initiative for Asthma 2021 guide evidence-based clinical decision making. However, given the present state of health disparities by age, income, and race, the equitable implementation and dissemination of these guidelines will be unlikely without further guidance. This work group report reviews the current state of the new asthma guideline implementation; presents updated evidence-based therapeutic options with attention to specific patient populations; and addresses barriers to the implementation of these guidelines in minoritized, historically marginalized, and underresourced communities. Allergists and immunologists can use practical ways to accomplish the goals of improved asthma care access and advanced asthma care across the life span, with specific considerations to historically marginalized populations. Modifiable barriers to guideline implementation include financial barriers, environmental factors, and allergy subspecialty access and care coordination. Various programs to improve access to guideline-based asthma care include community programs, school-based asthma programs, and digital health solutions, with an emphasis on reducing disparities by race.

Exploring research impact models: A systematic scoping review

This article explores the models and frameworks developed on “research impact’. We aim to provide a comprehensive overview of related literature through scoping study method. The present research investigates the nature, objectives, approaches, and other main attributes of the research impact models. It examines to analyze and classify models based on their characteristics. Forty-seven studies and 10 reviews published between 1996 and 2020 were included in the analysis. The majority of models were developed for the impact assessment and evaluation purposes. We identified three approaches in the models, namely outcome-based, process-based, and those utilized both of them, among which the outcome-based approach was the most frequently used by impact models and evaluation was considered as the main objective of this group. The process-based ones were mainly adapted from the W.K. Kellogg Foundation logic model and were potentially eligible for impact improvement. We highlighted the scope of processes and other specific features for the recent models. Given the benefits of the process-based approach in enhancing and accelerating the research impact, it is important to consider such approach in the development of impact models. Effective interaction between researchers and stakeholders, knowledge translation, and evidence synthesis are the other possible driving forces contributing to achieve and improve impact.

[The role of written action plans in the management of asthma]

The Written Action Plan is a tool designed to help people with asthma to manage their condition when they experience an exacerbation. Asthma guidelines are consistent in their recommendation that action plans are useful for all people with asthma, but implementation is not systematic. The evidence base for such plans is limited because of methodological biases, but does support their effectiveness. The recommended action plan involves different color-coded zones which advise patients to adjust their management, such as increasing the level of daily treatment, or introducing oral corticosteroids based on symptoms and peak expiratory flow measurements. Recommendations are much less clear as to how to encourage patients to adopt and take ownership of their plan, although they all recommend that written action plans be incorporated into therapeutic education programs. The published literature shows that those caring for people with asthma may not support action plans because they are uncomfortable with the necessary educational posture and as a consequence of this they are under-utilized by patients. Patient-centered therapeutic education principles help us understand both how to encourage the patient want to have a written action plan and how to co-create it with them so that it is useful and meaningful in their life in order to make it more than just a disconnected tool.

Adult Asthma Diagnosis: Physician Reported Challenges in Alberta-Based Primary Care Practices

Introduction

An estimated 8.1% of Canadians adults have asthma. While there are challenges associated with the use of objective measurement of lung function in the diagnosis of asthma, we are uncertain of the barriers that impact the use of objective measures, and have limited understanding of the challenges experienced by primary care providers in diagnosis of asthma. The objectives of this quality improvement initiative were to identify primary care providers’ methods of diagnosing asthma and to identify challenges with diagnosis.

Methods

An online survey was disseminated using a snowball methodology.

Setting

Primary care practices in Alberta, Canada.

Participants

A total of 84 primary care providers completed the survey.

Main Outcome Measures

Participants were asked their ideal and sufficient methods for diagnosing asthma and to identify challenges in their practice related to asthma diagnosis.

Results

They identified full pulmonary function testing (54%), pre- and postbronchodilator spirometry (54%), complete history and physical (42%), peak flow measurement overtime (26%), pulmonary consult (26%), and trial of asthma medication(s) (23%), as ideal methods of diagnosing asthma. The most significant barriers to diagnosis included episodic care–care provided typically during times of worsening symptoms without ongoing preventative/maintenance care (55%), patient follow-up (44%), conflict between clinical impression and pulmonary function results (43%), patient already on asthma medications (43%), and interpreting spirometry/pulmonary function results (39%).

Conclusion

The results of this survey indicate that the majority of primary care providers would choose full pulmonary function testing or pre- and postbronchodilator spirometry as the ideal methods of diagnosing asthma. However, barriers related to the nature of asthma care, patient factors, and challenges with diagnostic testing create challenges. This study also highlights that primary care providers have adapted to challenges in leveraging objective measurement and may rely upon other methods for diagnosis such as trials of medications.

Are there specific clinical characteristics associated with physician's treatment choices in COPD?

Background

The number of pharmacological agents and guidelines available for COPD has increased markedly but guidelines remain poorly followed. Understanding underlying clinical reasoning is challenging and could be informed by clinical characteristics associated with treatment prescriptions.

Methods

To determine whether COPD treatment choices by respiratory physicians correspond to specific patients’ features, this study was performed in 1171 patients who had complete treatment and clinical characterisation data. Multiple statistical models were applied to explain five treatment categories: A: no COPD treatment or short-acting bronchodilator(s) only; B: one long-acting bronchodilator (beta2 agonist, LABA or anticholinergic agent, LAMA); C: LABA+LAMA; D: a LABA or LAMA + inhaled corticosteroid (ICS); E: triple therapy (LABA+LAMA+ICS).

Results

Mean FEV1 was 60% predicted. Triple therapy was prescribed to 32.9% (treatment category E) of patients and 29.8% received a combination of two treatments (treatment categories C or D); ICS-containing regimen were present for 44% of patients altogether. Single or dual bronchodilation were less frequently used (treatment categories B and C: 19% each). While lung function was associated with all treatment decisions, exacerbation history, scores of clinical impact and gender were associated with the prescription of > 1 maintenance treatment. Statistical models could predict treatment decisions with a < 35% error rate.

Conclusion

In COPD, contrary to what has been previously reported in some studies, treatment choices by respiratory physicians appear rather rational since they can be largely explained by the patients’ characteristics proposed to guide them in most recommendations.

Family medicine physician teachers and residents' intentions to prescribe and interpret spirometry: a descriptive cross-sectional study

Background: Spirometry is the best test to demonstrate airway obstruction, but remains underused in primary care. Objectives: We assessed, among family medicine physician teachers and residents, their intention to prescribe spirometry in patients suspected of chronic obstructive pulmonary disease and their intention to interpret the results. This evaluation is based on the theoretical framework proposed by Godin et al. for the study of factors influencing healthcare professionals' behavior. Methods: Participants of this descriptive cross-sectional study were recruited from eight Family medicine units (FMUs) of Laval University's network. They completed a 23-item self-administered questionnaire measuring their intention to prescribe and to interpret spirometry as well as some determinants of this intention (beliefs about capabilities, beliefs about consequences, social influence and moral norm). Answers to each of the items were scored on a Likert scale (score 1 to 7) where a higher score indicated a greater agreement with the statement. Results: Of the 284 eligible physicians, 104 were included. The mean score ± standard deviation of physicians' intention to prescribe spirometry (6.6 ± 0.7) was higher than to interpret the results (5.8 ± 1.5). Mean scores for all determinants of intention measured were also higher for prescription than for interpretation of spirometry. Conclusion: The results suggest that participants have a very strong intention to prescribe spirometry. Although the intention to interpret the results is positive, it is weaker than for the prescription of the test. Further studies will be needed to assess the barriers to spirometry interpretation.

Stable COPD Treatment: Where are We?

The number of pharmacological treatments available for COPD has increased markedly in the last years, mostly corresponding to new agents, combinations and devices within know pharmacological classes. Hierarchizing these options is not straightforward since expected effects are limited by the intrinsically fixed character of the underlying lung damage. In addition, all options have not been directly compared face-to-face. Therefore, guidelines derive from some level of subjective interpretation of the available evidence. Determining which magnitude of change can be taken as clinically relevant is complex although crucial to define long-term strategies. Similarly, estimating not only the possible benefits but also the risks of treatments at the individual level is of major importance to guide choices. In the future biomarkers may be of help in that respect. They will hopefully emerge from progresses in systems biology and medicine. Before then, prescriptions should be restricted to the appropriate treatment indications, as established by high level studies and formalized by guidelines.

Validation of the patient-completed asthma knowledge questionnaire (PAKQ)

BACKGROUND

Asthma is often suboptimally controlled, in part due to patients' disease knowledge. Understanding patients' knowledge, prior to education may help in individualizing content. However, there are no well validated or internationally relevant patient asthma knowledge questionnaires available.

OBJECTIVE

To translate and validate the rigorously validated Questionnaire de connaissances sur l'asthme destiné aux patients adultes (QCA-PA) based on key points related to asthma knowledge and self-management accordingly to the Global Initiative for Asthma report.

METHODS

Based on Vallerand's methodology, a preliminary version of the "Patient-completed Asthma Knowledge Questionnaire" (PAKQ) was back-translated and evaluated by an expert committee. A sample of 20 individuals with asthma pretested the questionnaire, after which 62 adults were recruited. Sociodemographic data were collected and the PAKQ together with a comparator questionnaire (Consumer Questionnaire (CQ)) were completed. Fourteen days after the first visit, participants returned to recomplete both questionnaires; half were randomly selected to receive a one-on-one asthma education session and again completed both questionnaires immediately after education, and at 10 days follow-up.

RESULTS

The PAKQ showed good internal consistency (KR-20 = 0.77). Moderate correlation with CQ (r = 0.596, p = 0.01) attested to its concurrent validity. Confirmatory factor analyses confirmed a single factor structure. A repeated measures ANOVA showed its reproducibility (n = 21:F₍₁₎ = 3.578, p = 0.07, η_p² = 0.152) and responsiveness (n = 21:F₍₁₎ = 26.041, P < 0.05, η_p² = 0.566).

CONCLUSION

The PAKQ is a valid asthma knowledge questionnaire which is based on international asthma recommendations and could help healthcare professionals in individualizing educational interventions for people with asthma.

Use of SNOMED CT® and LOINC® to standardize terminology for primary care asthma electronic health records

OBJECTIVES

The burden of asthma ranks among the highest for chronic diseases. Interoperable electronic health records (EHRs) can improve the management of chronic diseases such as asthma by facilitating sharing of data between health care settings along the continuum of care. Terminology such as SNOMED CT® (Systematized Nomenclature of Medicine-Clinical Terms) and LOINC® (Logistical Observation Identifier Names and Codes) are prerequisites for interoperability of EHRs. We sought to determine the extent to which data elements in a validated asthma care map (ACM) are congruent with these terminologies.

METHODS

A certified asthma educator entered all 169 elements in the ACM into the SNOMED CT® browser. Matched elements were assigned a concept name, an identification number, and classified into a hierarchy. LOINC® terminology was reviewed for asthma-related pulmonary function tests (PFTs).

RESULTS

Forty-two percent of the ACM elements were complete matches to existing SNOMED CT® concepts, 24% partial matches, and 34% unmatched. Specific asthma control parameters were either complete (n = 3) or partial (n = 4) matches, but overall "asthma control" was unmatched. There were 92% complete or partial matches for PFT elements to SNOMED CT® and 83% to LOINC^®. Conclusions: The majority of ACM elements are congruent with standardized terminology, enabling EHR interoperability. Future requests for new concepts in SNOMED CT® and LOINC® should be pursued for asthma control parameters paramount to evidence-based practice.

Implementation of asthma clinical practice guidelines in primary care: A cross-sectional study based on the Knowledge-to-Action Cycle

OBJECTIVE

Based on the Knowledge-to-Action Cycle, we assessed the self-reported implementation and perception of asthma clinical practice guideline (CPG) recommendations in primary care physicians (PCPs), along with the barriers and facilitators to CPG use in primary care.

METHODS

We conducted a cross-sectional study. Using the extended Asthma Physicians' Practice Assessment Questionnaire^©, PCPs self-reported the following: their knowledge of 15 key asthma CPG recommendations, the perceived usefulness of each of these recommendations, their motivation to apply these recommendations, and their agreement with the content of these recommendations. Participants also reported the barriers and facilitators to CPG use in primary care.

RESULTS

Out of the 46 potential participants, 43 physicians completed the questionnaire (response rate: 93%). Results underlined care gaps regarding the provision of asthma education and written action plans, inhaler technique demonstrations, and assessment of patients' concerns. Results showed that the majority of physicians knew the key asthma CPG recommendations, but their motivation to implement them and the perceived usefulness of these recommendations varied from one proposal to another. Main barriers to the implementation of these recommendations were related to time and resources. PCPs stressed the importance of teamwork for enhancing the use of asthma CPGs in primary care.

CONCLUSIONS

Our results suggest that the implementation of asthma CPGs remains suboptimal in primary care. Interventions addressing the identified barriers and providing facilitators to asthma CPG implementation, such as continuing education, could be implemented and evaluated to sustain asthma CPG use in primary care settings.

An evidence-based, point-of-care tool to guide completion of asthma action plans in practice

Asthma action plans (AAPs) reduce healthcare utilisation, improve quality of life and are recommended across guidelines. However, fewer than 25% of patients receive an AAP, partly due to prescribers' inability to complete “yellow zone” instructions (how to intensify therapy for acute loss of control). We sought to review best evidence to develop a practical, evidence-based tool to facilitate yellow zone guidance in adults.

We reviewed recent asthma guidelines and adult studies addressing acute loss of asthma control (January 2010 to March 2016). We developed evidence-based rules for yellow zone therapy and operational guidelines to maximise adherence and minimise errors.

We reviewed three guidelines and 11 manuscripts (2486 abstracts screened). Recommendations were comparable but some areas lacked guidance. For 15/43 asthma regimens, the commonly recommended four- to five-fold yellow zone inhaled corticosteroid dose increase was problematic due to regulatory dose limits. We identified evidence-based alternatives for 8/15 regimens. Operational guidance included increasing to a maximum of four inhalations while maintaining baseline inhaler frequency and device in the yellow zone.

We developed a practical implementation tool to facilitate AAP delivery at the point of care, addressing existing gaps and uncertainties. Our tool should be implemented as part of a multifaceted approach to augment AAP usage.

Strategies for disseminating recommendations or guidelines to patients: a systematic review

Background

The aim of this systematic literature review was to assess what dissemination strategies are feasible to inform and educate patients about recommendations (also known as guidelines).

Methods

The search was performed in February 2016 in PubMed, Ebsco/PsycINFO, Ebsco/CINAHL and Embase. Studies evaluating dissemination strategies, involving patients and/or reaching patients, were included. A hand search and a search in the grey literature, also done in February 2016, were added. Searches were not restricted by language or publication type.

Publications that referred to (1) guideline(s) or recommendation(s), (2) dissemination, (3) dissemination with patients/patient organisations and (4) dissemination to patients/patient organisations were included in this article. Criteria 1 AND 2 were mandatory together with criteria 3 OR 4.

Results

The initial search revealed 3753 unique publications. Forty-seven articles met the inclusion criteria and were selected for detailed review. The hand search and grey literature resulted in four relevant articles. After reading the full text of the 47 articles, 21 were relevant for answering our research question. Most publications had low levels of evidence, 3 or 4 of the Oxford levels of evidence. One article had a level of evidence of 2(b).

This article gives an overview of tools and strategies to disseminate recommendations to patients. Key factors of success were a dissemination plan, written at the start of the recommendation development process, involvement of patients in this development process and the use of a combination of traditional and innovative dissemination tools. The lack of strong evidence calls for more research of the effectiveness of different dissemination strategies as well as the barriers for implementing a strategic approach of dissemination.

Conclusion

Our findings provide the first systematic overview of tools and strategies to disseminate recommendations to patients and patient organisations. Participation of patients in the whole process is one of the most important findings. These findings are relevant to develop, implement and evaluate more (effective) dissemination strategies which can improve health care.

[Development and validation of patient's knowledge measurement tools: The model of the Questionnaire de Connaissances sur l'Asthme destiné aux Patients Adultes (QCA-PA)]

INTRODUCTION

Poor asthma knowledge among asthmatic patients contributes to poor control of the disease. Education is a priority, but it needs a good assessment of the patient's knowledge.

AIM

To give a patient's knowledge questionnaire development method following the example of the Questionnaire de Connaissances sur l'Asthme destiné aux Patients Adultes (QCA-PA).

METHODS

The QCA-PA was developed according to Dussault, Valois and Frenette's seven steps and includes 54 "true/false/don't know" items. A total of 101 asthmatic adults completed the questionnaire four times during three visits over a period of about one month. On the second visit, it was answered twice, before and after an individualized education session on asthma.

RESULTS

The QCA-PA demonstrates different proofs of validity: content, response process, internal structure, relationship to other variables, and consequences of testing. Confirmatory factorial analysis showed a unidimensional structure.

CONCLUSIONS

QCA-PA is a new rigorously validated knowledge measurement tool based on the most recent international recommendations. It could help health professionals to better target their educational interventions towards asthma patients.

Does active dissemination of evidence result in faster knowledge transfer than passive diffusion?: An analysis of trends of the management of pediatric asthma and croup in US emergency departments from 1995 to 2009

OBJECTIVE

This study aimed to compare knowledge transfer (KT) in the emergency department (ED) management of pediatric asthma and croup by measuring trends in corticosteroid use for both conditions in EDs.

METHODS

A retrospective, cross-sectional study of the National Hospital Ambulatory Medical Care Survey data between 1995 and 2009 of corticosteroid use at ED visits for asthma or croup was conducted. Odds ratios (OR) were calculated using logistic regression. Trends over time were compared using an interaction term between disease and year and were adjusted for all other covariates in the model. We included children aged 2 to 18 years with asthma who received albuterol and were triaged emergent/urgent. Children aged between 3 months to 6 years with croup were included. The main outcome measure was the administration of corticosteroids in the ED or as a prescription at the ED visit.

RESULTS

The corticosteroid use in asthma visits increased from 44% to 67% and from 32% to 56% for croup. After adjusting for patient and hospital factors, this trend was significant both for asthma (OR, 1.07; 95% confidence interval [CI], 1.04-1.10) and croup (OR, 1.07; 95% CI, 1.03-1.12). There was no statistical difference between the 2 trends (P = 0.69). Hospital location in a metropolitan statistical area was associated with increased corticosteroid use in asthma (OR, 1.76; 95% CI, 1.10-2.82). Factors including sex, ethnicity, insurance, or region of the country were not significantly associated with corticosteroid use.

CONCLUSIONS

During a 15-year period, knowledge transfer by passive diffusion or active guideline dissemination resulted in similar trends of corticosteroid use for the management of pediatric asthma and croup.

Asthma and chronic obstructive pulmonary disease guideline implementation: lessons learned on recruitment of primary care physicians to a knowledge translation study

BACKGROUND

Implementation of current clinical practice guidelines in asthma and chronic obstructive pulmonary disease (COPD) is suboptimal. New implementation strategies should be developed and evaluated.

METHODS

The authors report the rationale and planned methods of a project that sought to use a multifaceted knowledge translation intervention consisting of interactive education, mentorship through quality circles and practice-based tools in primary care to address key asthma and COPD care gaps. The present study was aborted due to inadequate primary care physician recruitment. Accordingly, the authors provide a critical review of their recruitment strategies and discuss alternative approaches and examples based on previous literature.

DISCUSSION

These practical lessons and discussion seek to inform researchers involved in designing and recruiting for future knowledge translation studies addressing chronic disease management in primary care.

Major care gaps in asthma, sleep and chronic obstructive pulmonary disease: a road map for knowledge translation

Large gaps between best evidence-based care and actual clinical practice exist in respiratory medicine, and carry a significant health burden. The authors reviewed two key care gaps in each of asthma, chronic obstructive pulmonary disease and obstructive sleep apnea. Using the 'Knowledge-to-Action Framework', the nature of each gap, its magnitude, the barriers that cause and perpetuate it, and past and future strategies that might address the problem were considered. In asthma: disease control is ascertained inadequately, leading to a prevalence of poor asthma control of approximately 50%; and asthma action plans, a key component of asthma management, are provided by only 22% of physicians. In obstructive sleep apnea: disease is under-recognized, with sleep histories ascertained in only 10% of patients; and Canadian polysomnography wait times remain longer than recommended, leading to unnecessary morbidity and societal cost. In chronic obstructive pulmonary disease: a large proportion of patients seen in primary care remain undiagnosed, mainly due to underuse of spirometry; and <10% of patients are referred for pulmonary rehabilitation, despite strong evidence demonstrating its cost effectiveness. Given the prevalence of these chronic conditions and the size and nature of these gaps, the latter exact an important toll on patients, the health care system and society. In turn, complex barriers at the patient, provider and health care system levels contribute to each gap. There have been few previous attempts to bridge these gaps. Innovative and multifaceted implementation approaches are needed and have the potential to make a large impact on Canadian respiratory health.

Development and implementation of an electronic asthma record for primary care: integrating guidelines into practice

RATIONALE

Evidence-based practice may be enhanced by integrating knowledge translation tools into electronic medical records (EMRs). We examined the feasibility of incorporating an evidence-based asthma care map (ACM) into Primary Care (PC) EMRs, and reporting on performance indicators.

METHODS

Clinicians and information technology experts selected 69 clinical and administrative variables from the ACM template. Four Ontario PC sites using EMRs were recruited to the study. Certified Asthma Educators used the electronic ACM for patient assessment and management. De-identified data from consecutive asthma patients were automatically transmitted to a secure central server for analysis.

RESULTS

Of the four sites recruited, two sites using "stand-alone" EMR systems were able to incorporate the selected ACM variables into an electronic format and participate in the pilot. Data were received on 161 visits by 130 patients aged 36.5 ± 26.9 (mean ± SD) (range 2-93) years. Ninety-four percent (65/69) of the selected ACM variables could be analyzed. Reporting capabilities included: individual patient, individual site and aggregate reports. Reports illustrated the ability to measure performance (e.g. number of patients in control, proportion of asthma diagnoses confirmed by an objective measure of lung function), benchmark and use EMR data for disease surveillance (e.g. number of smokers and the individuals with suspected work-related asthma).

CONCLUSIONS

Integration of this evidence-based ACM into different EMRs was successful and permitted patient outcomes monitoring. Standardized data definitions and terminology are essential in order for EMR data to be used for performance measurement, benchmarking and disease surveillance.

Multidimensional analyses to assess the relations between treatment choices by physicians and patients' characteristics: the example of COPD

Background

In some situations, practice guidelines do not provide firm evidence-based guidance regarding COPD treatment choices, especially when large trials have failed to identify subgroups of particularly good or poor responders to available medications.

Methods

This observational cross-sectional study explored the yield of four types of multidimensional analyses to assess the associations between the clinical characteristics of COPD patients and pharmacological and non-pharmacological treatments prescribed by lung specialists in a real-life context.

Results

Altogether, 2494 patients were recruited by 515 respiratory physicians. Multiple correspondence analysis and hierarchical clustering identified 6 clinical subtypes and 6 treatment subgroups. Strong bi-directional associations were found between clinical subtypes and treatment subgroups in multivariate logistic regression. However, although the overall frequency of prescriptions varied from one clinical subtype to the other for all types of pharmacological treatments, clinical subtypes were not associated with specific prescription profiles. When canonical analysis of redundancy was used, the proportion of variation in pharmacological treatments that was explained by clinical characteristics remained modest: 6.23%. This proportion was greater (14.29%) for non-pharmacological components of care.

Conclusion

This study shows that, although pharmacological treatments of COPD are quantitatively very well related to patients’ clinical characteristics, there is no particular patient profile that could be qualitatively associated to prescriptions. This underlines uncertainties perceived by physicians for differentiating the respective effects of available pharmacological treatments. The methodology applied here is useful to identify areas of uncertainty requiring further research and/or guideline clarification.

Pan-Canadian REspiratory STandards INitiative for Electronic Health Records (PRESTINE): 2011 national forum proceedings

In a novel knowledge translation initiative, the Government of Ontario's Asthma Plan of Action funded the development of an Asthma Care Map to enable adherence with the Canadian Asthma Consensus Guidelines developed under the auspices of the Canadian Thoracic Society (CTS). Following its successful evaluation within the Primary Care Asthma Pilot Project, respiratory clinicians from the Asthma Research Unit, Queen's University (Kingston, Ontario) are leading an initiative to incorporate standardized Asthma Care Map data elements into electronic health records in primary care in Ontario. Acknowledging that the issue of data standards affects all respiratory conditions, and all provinces and territories, the Government of Ontario approached the CTS Respiratory Guidelines Committee. At its meeting in September 2010, the CTS Respiratory Guidelines Committee agreed that developing and standardizing respiratory data elements for electronic health records are strategically important. In follow-up to that commitment, representatives from the CTS, the Lung Association, the Government of Ontario, the National Lung Health Framework and Canada Health Infoway came together to form a planning committee. The planning committee proposed a phased approach to inform stakeholders about the issue, and engage them in the development, implementation and evaluation of a standardized dataset. An environmental scan was completed in July 2011, which identified data definitions and standards currently available for clinical variables that are likely to be included in electronic medical records in primary care for diagnosis, management and patient education related to asthma and COPD. The scan, sponsored by the Government of Ontario, includes compliance with clinical nomenclatures such as SNOMED-CT® and LOINC®. To help launch and create momentum for this initiative, a national forum was convened on October 2 and 3, 2011, in Toronto, Ontario. The forum was designed to bring together key stakeholders across the spectrum of respiratory care, including clinicians, researchers, health informaticists and administrators to explore and recommend a potential scope, approach and governance structure for this important project. The Pan-Canadian REspiratory STandards INitiative for Electronic Health Records (PRESTINE) goal is to recommend respiratory data elements and standards for use in electronic medical records across Canada that meet the needs of providers, administrators, researchers and policy makers to facilitate evidence-based clinical care, monitoring, surveillance, benchmarking and policy development. The focus initially is expected to include asthma, chronic obstructive pulmonary disease and pulmonary function standards elements that are applicable to many respiratory conditions. The present article summarizes the process and findings of the forum deliberations.

Educational and decision-support tools for asthma-management guideline implementation

Many international and national asthma guidelines are now available in large parts of the world, but they are not yet implemented appropriately. There is a gap between scientific evidence-based medicine and real clinical practice. Implementation of guidelines is highly complex. Special strategies are needed to encourage guideline-based, high-quality care. It is important to understand the contents, the format, and the learning strategies which physicians prefer for the dissemination of guidelines. Physicians prefer more concise and immediately available guidelines that are practical to use. Thus, asthma guidelines should be disseminated as convenient and easily accessible tools. Various education programs and decision-support tools have been designed and applied to the clinical management of asthma to solve these challenging problems. Many of them have been shown to be effective at increasing physicians' knowledge and adherence to asthma guidelines and improving patients' clinical outcomes. These educational and decision-support tools are expected to contribute to a narrowing of the gap between asthma guidelines and practice/implementation of the guidelines.

Asthma care pathways in the emergency department

PURPOSE OF REVIEW

The purpose of this review is to describe recent evidence of the efficacy and effectiveness of clinical pathways for the assessment and management of severe acute asthma in children and adults in the emergency department (ED). The review will highlight examples of successful knowledge translation initiatives and their ability to support adherence to Best Practice Guidelines.

RECENT FINDINGS

Recent studies reveal that management of pediatric and adult asthma in the ED setting often differs from that which is recommended in clinical practice guidelines. Single and multicenter North American studies have consistently found care gaps. Barriers to adherence to evidence-based management guidelines are numerous. Care pathways are knowledge translation tools that provide a means of applying knowledge translation principles to overcome these barriers, integrate guidelines into practice and optimize patient outcomes. Evidence from a recent Ontario multicenter asthma clinical pathway initiative is highlighted, demonstrating increased adherence to certain aspects of ED care, improved patient recollection of teaching done in the ED and increased referral rates. These findings strengthen the evidence supporting the development and implementation of standardized evidence-based asthma clinical pathways.

SUMMARY

Gaps between current and best practices persist for the management of asthma in children and adults in North American EDs. There is robust evidence in support of ED asthma clinical pathways to optimize asthma care and outcomes in this setting.

The Physicians' Practice Assessment Questionnaire on asthma and COPD

We describe a new tool, the Physicians' Practice Assessment Questionnaire (PPAQ), designed for the global self-assessment of implementation of asthma and COPD guidelines, as determined by the percentage of patients in whom physicians estimate that they implement guidelines key recommendations. Some of its properties were assessed by a group of 47 general practitioners (GPs), and test-retest data were obtained in repeating the questionnaire at a 5-week interval without intervention in a sub-group of 28 practitioners. Answers to the various questions were globally reproducible. The lowest scores (recommendations implemented in less than 50% of their patients) were: 1) for both asthma and COPD: referral for patient education, provision of a written action plan and regular assessment of inhaler technique, 2) for asthma: referral to a specialist for difficult to control asthma or uncertain diagnosis, and 3) for COPD: assessment of lung function and disability according to specific criteria and referral to a rehabilitation program. The analysis showed sufficient internal consistency for both questionnaires (Cronbach alphas 0.7617 for asthma and 0.8317 for COPD). Pearson's correlations indicated good test-retest (r = 0.6421, p = 0.0002 for asthma; r = 0.6801, p < 0.0001 for COPD). In conclusion, the PPAQ is a new tool to assess implementation of asthma and COPD guidelines; it has the potential to identify care gaps that can be specifically targeted for intervention.

Irreversible airway obstruction in asthma

Asthma is generally characterized by fully reversible airway obstruction. However, a significant proportion of asthma patients demonstrate an incomplete reversibility of airway obstruction (IRAO) despite optimal treatment and the absence of a significant smoking history. Such partially irreversible airway obstruction may be due to residual airway inflammation, particularly of the eosinophilic type, and structural changes. Risks factors for IRAO include reduced pulmonary function early in life, frequent exacerbations, smoking, continuing exposure to a sensitizing agent, and adult-onset asthma. IRAO is associated with increased disease severity and increased asthma-related morbidity and mortality. Optimal asthma control, including prevention of asthma exacerbations, smoking avoidance, and sufficient anti-inflammatory therapy, should be implemented in an effort to avoid an accelerated decline in lung function and the development or worsening of IRAO.

[Improving the control of asthma]

Asthma control is the cornerstone of monitoring for patients with this disease. Monitoring limited to questions of the type "how is your asthma?" underestimates the real effects of the disease. Measuring control requires assessing several criteria, which differ by the kinetics of their course during treatment. Basing monitoring on only a single criterion risks overestimating control, stepping down treatment too early, and losing control of the disease. In the case of inadequate control, uncontrolled comorbid conditions and aggravating factors or poor treatment adhesion must be sought before determining that the treatment itself is insufficient. After stepping up treatment, the chances of obtaining adequate control increase progressively with time, for at least a year. When the physician and patient jointly determine that the current treatment is the maximum acceptable, waiting may be a solution. Similarly, in seeking the minimal efficacious treatment, treatment must not be stepped down too rapidly. Once control is obtained, continuation of the treatment maintains long-term control for most patients.

Living with chronic obstructive pulmonary disease: a survey of patients' knowledge and attitudes

INTRODUCTION

Chronic obstructive pulmonary disease (COPD) is a common respiratory condition and the fourth leading cause of death in Canada. However, little is known about the impact of COPD on the lives and attitudes of individuals living with this condition. The purpose of this study was to determine whether Canadians with COPD are properly educated and supported, and to recommend solutions to any care gaps identified.

METHODS

A total of 389 Canadians were surveyed who were 40 years of age and older, physician diagnosed with COPD, and current or former smokers. The telephone survey contained 68 items and took 35 min to complete. COPD severity was classified according to symptom severity using the Medical Research Council (MRC) score.

RESULTS

Respondents tended to overestimate their disease severity and reported substantial symptom burden and psychosocial impact of living with COPD. Most individuals claimed to be well informed about COPD; however, their knowledge was poor in several domains including the causes of COPD, the consequences of inadequate therapy and the management of exacerbations. Family physicians were the main health care providers. A minority of respondents had seen a lung health educator. Only 34% had ever received a written action plan and only 33% had been told how to prevent an exacerbation.

CONCLUSIONS

The symptom burden and psychosocial impact of living with COPD is substantial. There are significant gaps in patients' knowledge about the management of COPD and little contact with lung health educators. Increased use of COPD-specific, self-management education programs may help rectify these care gaps.

Towards Excellence in Asthma Management: final report of an eight-year program aimed at reducing care gaps in asthma management in Quebec

BACKGROUND AND OBJECTIVES

Asthma care in Canada and around the world persistently falls short of optimal treatment. To optimize care, a systematic approach to identifying such shortfalls or 'care gaps', in which all stakeholders of the health care system (including patients) are involved, was proposed.

METHODS

Several projects of a multipartner, multidisciplinary disease management program, developed to optimize asthma care in Quebec, was conducted in a period of eight years. First, two population maps were produced to identify regional variations in asthma-related morbidity and to prioritize interventions for improving treatment. Second, current care was evaluated in a physician-patient cohort, confirming the many care gaps in asthma management. Third, two series of peer-reviewed outcome studies, targeting high-risk populations and specific asthma care gaps, were conducted. Finally, a process to integrate the best interventions into the health care system and an agenda for further research on optimal asthma management were proposed.

RESULTS

Key observations from these studies included the identification of specific patterns of noncompliance in using inhaled corticosteroids, the failure of increased access to spirometry in asthma education centres to increase the number of education referrals, the transient improvement in educational abilities of nurses involved with an asthma hotline telephone service, and the beneficial effects of practice tools aimed at facilitating the assessment of asthma control and treatment needs by general practitioners.

CONCLUSIONS

Disease management programs such as Towards Excellence in Asthma Management can provide valuable information on optimal strategies for improving treatment of asthma and other chronic diseases by identifying care gaps, improving guidelines implementation and optimizing care.

Improving knowledge transfer on chronic respiratory diseases: a Canadian perspective. How to translate recent advances in respiratory diseases into day-to-day care

BACKGROUND

Chronic diseases represent an increasing burden for health care systems. Ongoing research efforts provide regularly new scientific evidence on how optimize current medical care. In regard to respiratory diseases, as for other health problems, optimal management of these conditions has been summarized in recent consensus guidelines but implementation of these recommendations is still poor. Not only are the key messages of such guidelines often unknown to the practitioner and the patient but even when it is, they are often insufficiently integrated into current care, often related to behavioral, organizational and communication barriers.

METHODS

Literature review on the topic of Clinical Practice Guidelines implementation and reference to recent projects aimed at improving management of asthma in the province of Quebec and elsewhere, as models for such implementation process.

RESULTS

The basic principles of an effective translation of current knowledge into day-to-day care are known, but healthcare delivery structures, practice tools and resources, and regional/local leadership should be available to make it happen. Ideally, implementation requires a multidisciplinary effort of care providers, specialists, general practitioners, allied health professionals, patients and their family. The general public, health administrators and policy makers should also be aware of the consequences of poor management of these diseases and be supportive of the proposed initiatives. Finally, these last should be adequately evaluated to ensure their effectiveness and determine if they should be improved. Recently projects performed in Quebec have proposed disease management models to identify asthma care gaps and improve translation of current Guidelines into day-to-day care.

CONCLUSIONS

Although the human and socio-economical burden of chronic diseases is still increasing, their current management is still often deficient. In the recent decades, Practice Guidelines have been developed to guide Practitioners towards optimal care, but implementation of these Guides is still poor. Recent Canadian and International initiatives have proposed valid models to help address current care gaps.

Antibiotics used in the ambulatory management of acute COPD exacerbations

Study objectives

This study was conducted to describe the different antibiotics that are used in the home management of chronic obstructive pulmonary disease (COPD) exacerbations and to estimate the failure rates following the initiation of the antibiotic.

Methods

A cohort study was conducted. Patients enrolled in a COPD home management program were included in the analysis. Failure rates were defined as an additional prescription of an antibiotic, an emergency room visit, or a hospitalization for a COPD exacerbation in the 30 days following the initiation of the antibiotic.

Results

A total of 1180 episodes of antibiotic treatment were analyzed. Overall, 348 episodes led to a failure (29.5%). The most frequently used antibiotics were cefuroxime (45.9%) and ciprofloxacin (21.1%).

Conclusion

This project demonstrates that a wide range of antibiotics were prescribed to our population of COPD patients with a moderate to severe form of the disease. Many treatment failures (about 30%) occurred in the 30-day period following the initiation of the home therapy with an antibiotic. Clinicians should be aware of this high failure rate when managing mild exacerbations of COPD at home.

Playing cards on asthma management: a new interactive method for knowledge transfer to primary care physicians

OBJECTIVES

To describe an interactive playing card workshop in the communication of asthma guidelines recommendations, and to assess the initial evaluation of this educational tool by family physicians.

DESIGN

Family physicians were invited to participate in the workshop by advertisements or personal contacts. Each physician completed a standardized questionnaire on his or her perception of the rules, content and properties of the card game.

SETTING

A university-based continuing medical education initiative.

PARTICIPANTS

Primary care physicians.

MAIN OUTCOME MEASURES

Physicians' evaluation of the rules, content and usefulness of the program.

RESULTS

The game allowed the communication of relevant asthma-related content, as well as experimentation with a different learning format. It also stimulated interaction in a climate of friendly competition. Participating physicians considered the method to be an innovative tool that facilitated reflection, interaction and learning. It generated relevant discussions on how to apply guideline recommendations to current asthma care.

CONCLUSIONS

This new, interactive, educational intervention, integrating play and scientific components, was well received by participants. This method may be of value to help integrate current guidelines into current practice, thus facilitating knowledge transfer to caregivers.

Diagnostic imaging practice guidelines for musculoskeletal complaints in adults--an evidence-based approach: introduction

PURPOSE

Imaging technology can improve patient outcomes by allowing greater precision in diagnosing and treating patients. However, there is evidence that overuse, underuse, and misuse of imaging services occur. The purpose of this project was to develop evidence-based diagnostic imaging practice guidelines for musculoskeletal complaints for use by doctors of chiropractic and other primary health care professionals.

METHODS

An electronic search of the English and French language literature (phase 1) was conducted on several databases. Cross references, and references provided by clinicians, were also used. Independent assessment of the quality of the citations used to support recommendations in the guidelines was performed using the QUADAS, the AGREE,and the SPREAD evaluation tools. A first draft of a diagnostic imaging practice guideline was produced, using the European Commission's Referral Guidelines for Imaging document as a template. Results were sent to 12 chiropractic specialists for a first external review. A modified Delphi process, including 149 international experts, was used to generate consensus on recommendations for diagnostic imaging studies. The reliability of proposed recommendations was further tested on field chiropractors and on a group of specialists both in chiropractic and in medicine in both Canada and the United States. All recommendations were graded according to the strength of the evidence.

RESULTS

The research procedure resulted in the recommendations for diagnostic imaging guidelines of adult extremity and spine disorders supported by more than 685 primary and secondary citations. High levels of agreement among Delphi panelists were reached for all proposed recommendations. Comments received by specialists were generally very favorable and reflected high levels of agreement with the proposed recommendations, perceived ease of use of guidelines, and implementation feasibility.

CONCLUSIONS

These evidence-based diagnostic imaging practice guidelines are intended to assist chiropractors and other primary care providers in decision making on the appropriate use of diagnostic imaging for specific clinical presentations. In all cases, the guidelines are intended to be used in conjunction with sound clinical judgment and experience. Application of these guidelines should help avoid unnecessary radiographs, increase examination precision,and decrease health care costs without compromising the quality of care. All guidelines are documents to be refined and modified regularly with new information and experience.

The Current State of Cough Research: The Clinician’s Perspective

Cough is one of the most common reasons for medical consultation and it is responsible for a large human and socioeconomic burden. Current guidelines provide a useful framework for cough management and summarize current knowledge of causes and optimal testing sequences and treatments of cough. However, research is needed on the role of noninvasive airway inflammation measurement in assessing etiology; optimal treatment of postinfectious cough or cough due to gastroesophageal reflux disease; protussive treatment; causes of chronic cough in immunocompromised hosts; and characteristics and management of psychogenic cough. The effects of the use or nonuse of evidence-based guidelines should be documented. An empiric, integrative approach to management of chronic cough also needs further validation.

Variability in asthma: symptom perception, care, and outcomes

Asthma remains a global respiratory health concern. Substantial variations in asthma outcomes persist in Canada despite the dissemination of national management guidelines. Many factors and their interactions presumably contribute to variations in outcomes, including asthma prevalence, severity, symptom recognition, self-management behaviour, access to care, and management. This article reviews the physiology of symptom perception in asthma, specifically the role of dynamic lung hyperinflation (DH) on the perception of the intensity and quality of dyspnea in asthma, and the link between blunted perception and life-threatening asthma. Additionally, the magnitude and correlates of regional variation in emergency department visit rates and hospitalizations for asthma in Ontario are reviewed.

Impacts of a provincial asthma guidelines continuing medical education project: The Ontario Asthma Plan of Action's Provider Education in Asthma Care Project

BACKGROUND

The Ontario Ministry of Health and Long-Term Care funded the Ontario Lung Association to develop and implement a continuing medical education program to promote implementation of the Canadian asthma guidelines in primary care.

OBJECTIVES

To determine baseline knowledge, preferred learning format, satisfaction with the program and reported impact on practice patterns.

METHODS

A 3 h workshop was developed that combined didactic presentations and small group case discussions. Outcome measures included a workshop evaluation, baseline assessment of asthma management knowledge and three-month postreflective evaluations.

RESULTS

One hundred thirty-seven workshops were delivered to 2783 primary care providers (1313 physicians, 1470 allied health) between September 2002 and March 2005. Of the 2133 participants, 1007 physicians and 1126 allied health professionals submitted workshop evaluations. Most (98%) of the attendees indicated they would recommend the workshop to a colleague. The majority preferred the combination of didactic lecture plus interactive case discussions. A subset of physicians provided consent to use these data for research (n=298 pediatric and 288 adult needs assessments; n=349 postreflective evaluations). Important needs identified included appropriate medication for chronic asthma and development of written action plans. On the postreflective evaluations, 88.7% remained very satisfied, 95.5% reported increased confidence, 91.9% reported an influence on practice and 67.2% reported using a written action plan.

CONCLUSIONS

This continuing medical education program addresses identified needs of primary care providers. Participants reported improvements in asthma care, including prescribing practices, use of spirometry and written action plans. Similar programs should be considered as part of multifaceted asthma guidelines dissemination and implementation initiatives in other provinces and nationally.

Can access to spirometry in asthma education centres influence the referral rate by primary physicians for education?

BACKGROUND AND OBJECTIVES

Asthma remains uncontrolled in a large number of asthmatic patients. Recent surveys have shown that a minority of asthmatic patients are referred to asthma educators. The objective of the present study was to assess the influence of increased access to spirometry in asthma education centres (AECs) on the rate of patient referrals to these centres by general practitioners.

METHODS

A one-year, prospective, randomized, multicentric, parallel group study was conducted over two consecutive periods of six months each, with added spirometry being offered in the second six-month period to the experimental group. Ten AECs were enrolled in the project. An advertisement describing the AECs' services was sent by mail to a total of 303 general practitioners at the start of each period, inviting them to refer their patients. Measures of the frequency of medical referrals to the AECs were assessed for each period.

RESULTS

The group of AECs randomly selected for spirometry in the second six-month period received 48 medical referrals during the first period and 32 during the second one, following proposed spirometry. AECs that had not offered spirometry received five referrals during the first period and seven during the second period. One AEC withdrew a few weeks after the study began and others encountered administrative problems, reducing their ability to provide interventions.

CONCLUSIONS

Referral to AECs is not yet integrated into the primary care of asthma and offering more rapid access to spirometry in the AECs does not seem to be a significant incentive for such referrals.

GINA guidelines on asthma and beyond

Clinical guidelines are systematically developed statements designed to help practitioners and patients make decisions regarding the appropriate health care for specific circumstances. Guidelines are based on the scientific evidence on therapeutic interventions. The first asthma guidelines were published in the mid 1980s when asthma became a recognized public health problem in many countries. The Global Initiative on Asthma (GINA) was launched in 1995 as a collaborative effort between the NHLBI and the World Health Organization (WHO). The first edition was opinion-based but updates were evidence-based. A new update of the GINA guidelines was recently available and it is based on the control of the disease. Asthma guidelines are prepared to stimulate the implementation of practical guidelines in order to reduce the global burden of asthma. Although asthma guidelines may not be perfect, they appear to be the best vehicle available to assist primary care physicians and patients to receive the best possible care of asthma.
