Barriers to delivering asthma care: a qualitative study of general practitioners

Asthma and Rhinitis Through the Lifespan of Nonpregnant Women

Increasingly, clinical practice guidelines advocate a precision medicine-based approach to care for asthma. This focus requires knowledge of not only different asthma phenotypes and their associated biomarkers but also sex and gender differences through the lifespan. Evidence continues to build in favor of different lifetime prevalence, clinical presentations, responses to management, and long-term prognosis of asthma. Women transition through many biological and psychosocial phases in their lives, all of which may interact with, and influence, their health and well-being. Historically, explanations have focused on hormonal effects on asthma in reproductive life, but a greater understanding of mechanisms starting before birth and changing over a lifetime is now possible, with immunologic, inflammatory, and hormonal factors playing a role. This article describes the evidence for the differences in asthma and rhinitis between men and women at different stages of life, the potential underlying mechanisms that contribute to this, and the implications for management and research. Future research studies should systematically report sex differences in asthma so that this knowledge can be used to develop a personalized approach to care, to achieve best possible outcomes for all.

Trend of Bronchial Hyperresponsiveness to Methacholine as a Cost Predictor of Mild-to-Moderate Asthma: A Twelve-Month Survey in Teenagers

Bronchial asthma is characterized by variable airflow obstruction, airway inflammation, and bronchial hyperresponsiveness (BHR) to non-specific stimuli. The role of underlying airway inflammation and of related long-lasting BHR has been suboptimally investigated in teenagers with mild-to-moderate asthma, as has the corresponding economic impact over time. The aim of the present study was to calculate the cost of mild-to-moderate atopic asthma in teenagers arising from their degree of persisting BHR over a twelve-month period.

METHODS

Patients aged 12-18 years with mild-to-moderate symptoms treated with fluticasone fumarate/vilanterol 92/22 mcg daily were retrospectively followed for 12 months. Usual spirometric parameters, BHR to methacholine (MCh), and resource consumption (visits, hospitalizations, systemic steroids and/or antibiotics courses, school days off) were assessed at recruitment (the index date) and after 6 and 12 months. Adherence to treatment was also calculated. The cost of asthma was calculated based on Italian tariffs and published papers. The trend over time in BHR and the association between response to MCh and total cost were investigated by using regression models adjusted for repeated measures.

RESULTS

106 teenagers (53 males, age 15.9 ± 1.6 years) were investigated. The annual cost of asthma proved significantly related to the BHR trend: every increment of a factor 10 in the response to MCh was associated with a saving of EUR 184.90 (95% CI -305.89 to -63.90). BHR was progressively optimized after 6 and 12 months in relation to the patients' compliance to treatment (≥70% of prescribed inhalation doses).

CONCLUSIONS

the usual spirometric parameters are largely insufficient to reflect the effects of underlying persistent inflammation in milder forms of asthma in teenagers. In terms of clinical governance, the periodic assessment of non-specific BHR is the appropriate procedure from this point of view. Non-specific BHR proves a reliable procedure for predicting and monitoring the economic impact of mild-to-moderate asthma in teenagers over time.

Reductions in inhaler greenhouse gas emissions by addressing care gaps in asthma and chronic obstructive pulmonary disease: an analysis

INTRODUCTION

Climate change from greenhouse gas (GHG) emissions represents one of the greatest public health threats of our time. Inhalers (and particularly metred-dose inhalers (MDIs)) used for asthma and chronic obstructive pulmonary disease (COPD), constitute an important source of GHGs. In this analysis, we aimed to estimate the carbon footprint impact of improving three distinct aspects of respiratory care that drive avoidable inhaler use in Canada.

METHODS

We used published data to estimate the prevalence of misdiagnosed disease, existing inhaler use patterns, medication class distributions, inhaler type distributions and GHGs associated with inhaler actuations, to quantify annual GHG emissions in Canada: (1) attributable to asthma and COPD misdiagnosis; (2) attributable to overuse of rescue inhalers due to suboptimally controlled symptoms; and (3) avoidable by switching 25% of patients with existing asthma and COPD to an otherwise comparable therapeutic option with a lower GHG footprint.

RESULTS

We identified the following avoidable annual GHG emissions: (1) ~49 100 GHG metric tons (MTs) due to misdiagnosed disease; (2) ~143 000 GHG MTs due to suboptimal symptom control; and (3) ~262 100 GHG MTs due to preferential prescription of strategies featuring MDIs over lower-GHG-emitting options (when 25% of patients are switched to lower GHG alternatives). Combined, the GHG emission reductions from bridging these gaps would be the equivalent to taking ~101 100 vehicles off the roads each year.

CONCLUSIONS

Our analysis shows that the carbon savings from addressing misdiagnosis and suboptimal disease control are comparable to those achievable by switching one in four patients to lower GHG-emitting therapeutic strategies. Behaviour change strategies required to achieve and sustain delivery of evidence-based real-world care are complex, but the added identified incentive of carbon footprint reduction may in itself prove to be a powerful motivator for change among providers and patients. This additional benefit can be leveraged in future behaviour change interventions.

The Extra Cost Due to Non-Adherence to Inhaled Treatments in Adolescents with Mild-to-Moderate Persistent Asthma

Bronchial asthma has a high socio-economic impact in Western countries. Low adherence to prescribed inhalation treatments contributes to poor asthma control and the higher utilization of healthcare resources. Although adolescents usually do not comply with long-term inhaled treatments prescribed on a regular basis, the related economic consequences still are poorly investigated in Italy.

AIM

A 12-month estimation of the economic impact of non-adherence to inhalation treatments in adolescents with mild-to-moderate atopic asthma.

METHODS

Non-smoking adolescents aged 12-19 years, without any significant comorbidity, prescribed with inhaled cortico-steroids (ICS) or ICS/long-acting beta(2)-adrenergics (LABA) via dry powder inhalers (DPIs) on a regular basis were automatically selected from the institutional database. Spirometric lung function, clinical outcomes, and pharmacological information were collected. The adolescents' adherence to their prescribed regimen was calculated monthly. Adolescents were divided in two sub-groups based on their adherence to prescriptions: ≤70% (not adherent) or >70% (adherent), and statistically compared (Wilcoxon test, assuming p < 0.05).

RESULTS

Overall, 155 adolescents fulfilled the inclusion criteria (males, 49.0%; mean age, 15.6 years ± 2.9 SD; mean BMI, 19.1 ± 1.3 SD). Mean values of lung function were: FEV1 = 84.9% pred. ± 14.8 SD, FEV1/FVC = 87.9 ± 12.5 SD; MMEF = 74.8% pred. ± 15.1 SD and V25 = 68.4% pred. ± 14.9 SD. ICS had been prescribed in 57.4% of subjects and ICS/LABA in 42.6%. Mean adherence to original prescriptions was 46.6% ± 9.2 SD in non-adherent and 80.3% ± 6.6 SD in adherent adolescents, respectively (p < 0.001). The mean rates of hospitalizations, exacerbations, and GP visits; the average duration of absenteeism; the frequency of systemic steroids and antibiotics courses needed over the study period were significantly and substantially lower in adolescents adherent to prescriptions (all p < 0.001). The mean total annual extra cost calculated in the two sub-groups was EUR 705.8 ± 420.9 SD in non-adherent adolescents and EUR 192.1 ± 68.1 SD in adherent adolescents, respectively (p < 0.001), which was 3.7 times higher than in non-adherent adolescents.

CONCLUSIONS

In adolescents, the clinical control of mild-to-moderate atopic asthma is directly and strictly related to the degree of adherence to prescribed inhalation therapies. All clinical and economic outcomes prove dramatically poor when adherence is low, and treatable asthma can be frequently mistaken for refractory asthma in these cases. Adolescents' non-adherence impacts the burden of the disease quite substantially. Much more effective strategies centered specifically on adolescents' asthma are needed.

Effects of Adherence to Once-Daily Treatment on Lung Function, Bronchial Hyperreactivity and Health Outcomes in Adolescents with Mild-to-Moderate Asthmoka: A Twelve-Month Survey

Adolescents with asthma are usually insufficiently adherent to regular inhalation treatments, thus limiting their effectiveness. The aim of this study is to investigate the role of adherence to single-inhaler long-acting LABA/ICS dry-powder combination o.d. in affecting lung function, bronchial hyperreactivity, and health outcomes over a twelve-month survey of a group of non-smoking adolescents with mild to moderate asthma. Methods: Age, gender, BMI and atopy, forced expiratory volume in 1 s (FEV1), maximum mid-expiratory flow (MMEF), and maximum expiratory flow at 25% of lung filling (MEF25) were assessed via a Boolean selection process from the institutional database at recruitment, as well as after 6 and 12 months, together with the incidence of exacerbation, school days that were taken off, GP and specialist visits, and systemic steroid and/or antibiotic courses. Adherence was checked monthly via a direct telephone call. Statistics were calculated with an ANOVA trend analysis, assuming p < 0.05. Results: Two well-matched sample groups of 54 subjects each were obtained. The mean annual adherence to treatment ranged from 48.2% doses ± 10.9 sd to 79.3% doses ± 8.8 sd (p < 0.001), regardless of age and gender. Only adolescents that adhered to the o.d. ICS/LABA inhalation regimen progressively achieved complete control of all lung function parameters (FEV1: 0.001; MMEF: p < 0.002; MEF25 < 0.001; <0.001), minimized their bronchial hyperreactivity (p < 0.001), and optimized all health outcomes (p < 0.001—p < 0.002) over the survey duration. Discussion: A good adherence to treatment is essential for asthma management, particularly in young patients. Factors that are totally independent of the complexity of the therapeutic regimen adopted (namely, only a once-daily inhalation in the present survey) probably represent the major reasons limiting the adolescents’ adherence. Cultural, educational, behavioral, and psychological factors are frequently involved, are difficult to control, and can present barriers to adolescents’ asthma management. Further studies aiming to deeply understand and possibly remove the reasons for such adolescents’ attitudes are needed, in cooperation with actions oriented in this direction by families, educators, and health professionals.

Availability and implementation of guidelines in European child primary health care: how can we improve?

BACKGROUND

Clinical guidelines are important for providing high-quality child primary health care. We aimed to assess the availability, use and achieved delivery of guidelines in the European Union (EU).

METHODS

We used a case study design to ascertain expert views on guidelines in six countries representing the EU. The experts completed an online questionnaire (response 49%), asking about their perception of guideline availability and implementation regarding three topics that represent prevention and care, i.e. vaccination, assessment of mental health and asthma care.

RESULTS

According to the respondents all countries had guidelines available for asthma care. For vaccination and mental health assessment respondents agreed to a lesser degree that guidelines were available. Implementation of guidelines for vaccination was mostly perceived as intended, but implementation of the guidelines for mental health assessment and asthma care was limited. Notable barriers were complexity of performance, and lack of training of professionals and of financial resources. Important facilitators for guideline implementation were the fit with routine practice, knowledge and skills of professionals and policy support. We found no clear relationship of guideline availability and implementation with type of child primary health care system of countries, but strong governance and sufficient financial resources seemed important for guideline availability.

CONCLUSIONS

Availability and implementation of clinical guidelines in child primary health care vary between EU countries. Implementation conditions can be strongly improved by adequate training of professionals, stronger governance and sufficient financial resources as facilitating factors. This can yield major gains in child health across Europe.

Caregivers' and healthcare professionals' perspective of barriers and facilitators to health service access for asthmatic children: a qualitative study

BACKGROUND

There is a high burden of asthma morbidity and mortality in Latin America. It has been proposed that this relates to limited access to diagnostic tests, asthma medications and specialised doctors. However, little is known of what caregivers of asthmatic children and healthcare professionals (HCPs) perceive as barriers and facilitators to adequate care. We aimed to explore the barriers and facilitators to asthma care access from caregivers' and HCP's perspective in an Ecuadorian low-resource setting.

METHODS

In 2017, we conducted 5 focus group discussions (FGD) with 20 caregivers of asthmatic children and 12 in-depth interviews with 3 paediatricians, 6 general doctors and 3 respiratory therapists in Esmeraldas city, Ecuador. FGDs and interviews were digitally recorded, transcribed, open-coded in QDA Miner, categorised using an interpretative phenomenological approach and analysed thematically. Barriers and facilitators were classified into availability, accessibility, acceptability and contact of healthcare services, based on Tanahashi model of health service access.

RESULTS

Limited resources, use of alternative medicines, fear of medication side-effects and lack of specific training for doctors and knowledge in families were common barriers for both caregivers and HCPs. Caregivers and HCPs proposed the implementation of public health asthma-focused programmes that would include close community-based follow-up of people with asthma, educational sessions for their families and public engagement activities. HCPs also suggested implementing training programmes on asthma management for general doctors.

CONCLUSION

Multiple barriers identified by caregivers and HCPs referred to economic and health service organisational issues, fear of side effects of medication or ineffective self-management. Increasing caregivers and HCPs' asthma knowledge, as well as HCPs' communication skills to establish a patient-centred approach with a shared decision-making process could improve asthma care in this setting.

Barriers and Enablers to Objective Testing for Asthma and COPD in Primary Care: A Systematic Review Using the Theoretical Domains Framework

BACKGROUND

Although guidelines have long recommended objective pulmonary function testing to diagnose asthma and chronic obstructive lung disease (COPD), many primary care patients receive a clinical diagnosis of asthma or COPD without objective testing. This often leads to unnecessary treatment with associated incremental costs and side-effects, and delays actual diagnosis.

RESEARCH QUESTION

What are the barriers and enablers to lung function testing for asthma and/or COPD in primary care?

STUDY DESIGN AND METHODS

We searched the literature for qualitative and quantitative studies reporting barriers and/or enablers to in-office or out-of-office lung function testing for diagnosing asthma and/or COPD, in primary care. Two reviewers independently screened abstracts and full texts; assessed methodological quality using the Mixed Methods Appraisal Tool; and extracted data from included studies. Identified barriers and enablers were categorized using the Theoretical Domains Framework (TDF), applying a pre-established coding manual.

RESULTS

We identified 7988 unique articles, reviewed 336 full-text articles, and included 18 studies in this systematic review. Of these 18, 12 were quantitative, 3 were qualitative, and 3 used mixed methods. All 18 addressed in-office testing and 11 also addressed out-of-office testing. Barriers and enablers overlapped for asthma and COPD, and in- and out-of-office settings. We identified more reported barriers (e.g. lack of knowledge of the usefulness of spirometry) than enablers (e.g. skills for performing reliable spirometry). Barriers mapped to 9 (of a possible 14) TDF domains (for both in- and out-of-office settings). Enablers mapped to three domains for in-office testing and five domains for out-of-office testing.

INTERPRETATION

Barriers to objective testing for airways disease in primary care are complex and span many theoretical domains. Correspondingly, a successful intervention must leverage multiple behaviour change techniques. A theory-based, multifaceted intervention to address underuse of diagnostic testing for asthma or COPD should now be developed and tested.

Assessment of Variation in Care Following Hospital Discharge for Children with Acute Asthma

Purpose

To evaluate potential variation in care management pathways following hospital discharge for children with asthma in New South Wales, Australia.

Methods

A cross-sectional web-based survey was conducted in emergency departments (EDs) and paediatric units of public hospitals with more than five paediatric beds within New South Wales, Australia, between July 2018 and March 2019. Nursing and medical staff in EDs and paediatric units who had cared for children aged under 18 years with asthma in the preceding 12 months were invited to participate in this study. Outcome measures included use of clinical practice guidelines and asthma action plan (AAP); advice on post-hospitalization follow-up; provision of asthma education for parents/carers; availability of community-based asthma services; communication with schools/childcare services.

Results

A total of 502 participants (236 nursing and 266 medical staff, response rate=22%) from 37 hospitals were included. Overall, the use of AAP was not universal (median=90%; IQR=81–96%) with significant difference across local health districts (LHDs) (88.6%, 95% CI=85.4–91.3) and between EDs and paediatric wards (p=9.4×10⁻⁹); and a range of asthma clinical practice guidelines were used. Post-hospitalization follow-up within 2–3 days was recommended by 70% of the respondents, but only 8% reported that hospitals had a system in place to ensure follow-up compliance. Formal asthma education sessions (27% respondents) were seldom provided to parents/carers during hospital stays, especially in EDs (14% respondents). Less than 50% of the respondents were aware of any asthma community services for children and only 4% reported that schools/childcare services were notified about the child’s hospital admission for an asthma flare up.

Conclusion

There are marked variations in the post-hospitalization asthma care and community management for children in NSW. An integrated standardized model of care may improve health outcomes in children with asthma.

Outpatient Management of Bronchial Asthma: A Comparative Analysis Between Guideline-Directed Management and Usual Management

Background

Bronchial asthma is a common controllable disease that causes a serious economic and social burden. The Global Initiative for Asthma (GINA) was developed to help guide clinicians in appropriate management of asthma. Despite the existence of published guidelines, common practice in many primary care clinics follows usual care based on clinical gestalt. This study aims to determine if there is a statistically significant difference in outcomes between patients receiving guideline-directed therapy when compared to those receiving usual clinician therapy.

Methods

A total of 300 patients were included in this study. Among them, 139 patients received guideline-directed medical therapy (GDMT group) and 161 received usual medical therapy (UMT group). Logistic regression models were utilized to determine if there was a significant difference in outcomes for patients comparing number of exacerbations and number of hospitalizations.

Results

More patients in GDMT group suffered from recorded exacerbations in the prior year with 43.9% having one, 3.6% having two, and 0.7% having three, compared to the frequencies of exacerbations in the UMT group (29.2%, 1.9%, and 1.2%, respectively) (P < 0.05). Cumulative number of hospitalizations due to asthma exacerbations in the prior year was also higher in GDMT group compared to the UMT group (one in 5.8% GDMT vs. 3.1% UMT; two in 0.0% GDMT vs. 0.6% UMT) without statistically significant difference (P = 0.349).

Conclusions

Primary care providers’ adherence to the 2018 GINA guidelines for asthma treatment did not offer benefit to patient outcomes, such as number of exacerbations or hospitalizations, compared to the usual medical care of bronchial asthma. Patient-tailored care may offer reduction in the rates of exacerbations and hospitalization.

The Electronic Asthma Management System (eAMS) improves primary care asthma management

A high prevalence of suboptimal asthma control is attributable to known evidence–practice gaps. We developed a computerised clinical decision support system (the Electronic Asthma Management System (eAMS)) to address major care gaps and sought to measure its impact on care in adults with asthma.

This was a 2-year interrupted time-series study of usual care (year 1) versus eAMS (year 2) at three Canadian primary care sites. We included asthma patients aged ≥16 years receiving an asthma medication within the last 12 months. The eAMS consisted of a touch tablet patient questionnaire completed in the waiting room, with real-time data processing producing electronic medical record-integrated clinician decision support.

Action plan delivery (primary outcome) improved from zero out of 412 (0%) to 79 out of 443 (17.8%) eligible patients (absolute increase 0.18 (95% CI 0.14–0.22)). Time-series analysis indicated a 30.5% increase in physician visits with action plan delivery with the intervention (p<0.0001). Assessment of asthma control level increased from 173 out of 3497 (4.9%) to 849 out of 3062 (27.7%) eligible visits (adjusted OR 8.62 (95% CI 5.14–12.45)). Clinicians escalated controller therapy in 108 out of 3422 (3.2%) baseline visits versus 126 out of 3240 (3.9%) intervention visits (p=0.12). At baseline, a short-acting β-agonist alone was added in 62 visits and a controller added in 54 visits; with the intervention, this occurred in 33 and 229 visits, respectively (p<0.001).

The eAMS improved asthma quality of care in real-world primary care settings. Strategies to further increase clinician uptake and a randomised controlled trial to assess impact on patient outcomes are now required.

The Electronic Asthma Management System is a systematically developed and evidence-based computerised decision support tool that engages both patients and healthcare providers to improve the quality of asthma care in real-world primary care settingshttp://ow.ly/w43Z30nxALB

Large care gaps in primary care management of asthma: a longitudinal practice audit

OBJECTIVES

Care gaps in asthma may be highly prevalent but are poorly characterised. We sought to prospectively measure adherence to key evidence-based adult asthma practices in primary care, and predictors of these behaviours.

DESIGN

One-year prospective cohort study employing an electronic chart audit.

SETTING

Three family health teams (two academic, one community-based) in Ontario, Canada.

PARTICIPANTS

884 patients (72.1% female; 46.0±17.5 years old) (4199 total visits; 4.8±4.8 visits/patient) assigned to 23 physicians (65% female; practising for 10.0±8.6 years).

MAIN OUTCOME MEASURES

The primary outcome was the proportion of visits during which practitioners assessed asthma control according to symptom-based criteria. Secondary outcomes included the proportion of: patients who had asthma control assessed at least once; visits during which a controller medication was initiated or escalated; and patients who received a written asthma action plan. Behavioural predictors were established a priori and tested in a multivariable model.

RESULTS

Primary outcome: Providers assessed asthma control in 4.9% of visits and 15.4% of patients. Factors influencing assessment included clinic site (p=0.019) and presenting symptom, with providers assessing control more often during visits for asthma symptoms (35.0%) or any respiratory symptoms (18.8%) relative to other visits (1.6%) (p<0.01).

SECONDARY OUTCOMES

Providers escalated controller therapy in 3.3% of visits and 15.4% of patients. Factors influencing escalation included clinic site, presenting symptom and prior objective asthma diagnosis. Escalation occurred more frequently during visits for asthma symptoms (21.0%) or any respiratory symptoms (11.9%) relative to other visits (1.5%) (p<0.01) and in patients without a prior objective asthma diagnosis (3.5%) relative to those with (1.3%) (p=0.025). No asthma action plans were delivered.

CONCLUSIONS

Major gaps in evidence-based asthma practice exist in primary care. Targeted knowledge translation interventions are required to address these gaps, and can be tailored by leveraging the identified behavioural predictors.

General Practitioners' experiences of asthma management in culturally and linguistically diverse populations

OBJECTIVE

The purpose of this study was to explore General Practitioners' experiences and perspectives about asthma management of culturally and linguistically diverse (CALD) people with asthma, particularly with reference to Arabic-speaking patients with low English proficiency (LEP).

METHODS

Semi-structured interviews guided by an interview protocol were conducted with general practitioners who deal with CALD patients with asthma. Participants were recruited from medical practices in Melbourne, Australia. Interviews were recorded and transcribed verbatim, followed by an inductive thematic analysis.

RESULTS

Data saturation was achieved after 21 interviews. Interviews lasted on average 30 minutes. Thematic analyses of the interview transcripts highlighted five key emergent themes: self-autonomy, language issues, accessibility and engagement, health literacy, and cultural/beliefs issues. Many participants highlighted that CALD patients do not self-manage their asthma. Miscommunication was mentioned by some participants as stemming from language barriers. Patients' difficulty in engagement with the health system, lower accessibility to health care, social isolation, and non-acclimatization were other issues participants highlighted as problems in providing effective asthma care to CALD patients. Participants reported finding it more difficult to treat CALD patients with asthma compared to local patients.

CONCLUSION

General practitioners perceived that treating culturally and linguistically diverse patients with asthma is difficult and many key barriers were observed to affect treatment. Cultural competence training for health professionals, as well as improving asthma and health system awareness in CALD patients with asthma and their carers, are key interventions that may address asthma management gaps in CALD patients.

Training physiotherapy students to educate patients: A randomised controlled trial

OBJECTIVE

To determine the effect of a training intervention on physiotherapy students' self-efficacy and skills in the area of patient education.

METHODS

Final year physiotherapy students were randomised to an intervention group or a wait-list control group. The intervention group participated in a 3.5h training intervention about patient education that included video observation, simulated patient practice and structured feedback. The control group did not receive any training. Self-efficacy was assessed at baseline (T1) and after the intervention (or no intervention for the control group) (T2). Patient education performance was assessed by a blinded rater from a video-recorded standardised clinical examination.

RESULTS

83 students were randomised to the intervention group and 81 students to the control group. There were no differences in demographic variables or self-efficacy between groups at baseline. There was significant improvement in self-efficacy for the intervention group, but no change for the control group. The intervention group performed significantly better than the control group for nine of the eleven performance items, with significantly higher scores overall.

CONCLUSION

A training intervention enhances physiotherapy student self-efficacy and performance in patient education.

PRACTICE IMPLICATION

Use of patient education training is recommended to enhance student self-efficacy and performance.

Evidence for models of diagnostic service provision in the community: literature mapping exercise and focused rapid reviews

Background

Current NHS policy favours the expansion of diagnostic testing services in community and primary care settings.

Objectives

Our objectives were to identify current models of community diagnostic services in the UK and internationally and to assess the evidence for quality, safety and clinical effectiveness of such services. We were also interested in whether or not there is any evidence to support a broader range of diagnostic tests being provided in the community.

Review methods

We performed an initial broad literature mapping exercise to assess the quantity and nature of the published research evidence. The results were used to inform selection of three areas for investigation in more detail. We chose to perform focused reviews on logistics of diagnostic modalities in primary care (because the relevant issues differ widely between different types of test); diagnostic ultrasound (a key diagnostic technology affected by developments in equipment); and a diagnostic pathway (assessment of breathlessness) typically delivered wholly or partly in primary care/community settings. Databases and other sources searched, and search dates, were decided individually for each review. Quantitative and qualitative systematic reviews and primary studies of any design were eligible for inclusion.

Results

We identified seven main models of service that are delivered in primary care/community settings and in most cases with the possible involvement of community/primary care staff. Not all of these models are relevant to all types of diagnostic test. Overall, the evidence base for community- and primary care-based diagnostic services was limited, with very few controlled studies comparing different models of service. We found evidence from different settings that these services can reduce referrals to secondary care and allow more patients to be managed in primary care, but the quality of the research was generally poor. Evidence on the quality (including diagnostic accuracy and appropriateness of test ordering) and safety of such services was mixed.

Conclusions

In the absence of clear evidence of superior clinical effectiveness and cost-effectiveness, the expansion of community-based services appears to be driven by other factors. These include policies to encourage moving services out of hospitals; the promise of reduced waiting times for diagnosis; the availability of a wider range of suitable tests and/or cheaper, more user-friendly equipment; and the ability of commercial providers to bid for NHS contracts. However, service development also faces a number of barriers, including issues related to staffing, training, governance and quality control.

Limitations

We have not attempted to cover all types of diagnostic technology in equal depth. Time and staff resources constrained our ability to carry out review processes in duplicate. Research in this field is limited by the difficulty of obtaining, from publicly available sources, up-to-date information about what models of service are commissioned, where and from which providers.

Future work

There is a need for research to compare the outcomes of different service models using robust study designs. Comparisons of ‘true’ community-based services with secondary care-based open-access services and rapid access clinics would be particularly valuable. There are specific needs for economic evaluations and for studies that incorporate effects on the wider health system. There appears to be no easy way of identifying what services are being commissioned from whom and keeping up with local evaluations of new services, suggesting a need to improve the availability of information in this area.

Internet-based self-management support for adults with asthma: a qualitative study among patients, general practitioners and practice nurses on barriers to implementation

OBJECTIVES

The aim of this study was to explore barriers among patients, general practitioners (GPs) and practice nurses to implement internet-based self-management support as provided by PatientCoach for asthma in primary care.

SETTING

Primary care within South Holland, the Netherlands.

PARTICIPANTS

Twenty-two patients (12 women, mean age 38 years), 21 GPs (6 women, mean age 52 years) and 13 practice nurses (all women, mean age 41 years).

DESIGN

A qualitative study using focus groups and interviews.

OUTCOMES

Barriers as perceived by patients, GPs and practice nurses to implementation of PatientCoach.

METHODS

10 focus groups and 12 interviews were held to collect data: 4 patient focus groups, 4 GP focus groups, 2 practice nurse focus group, 2 patient interviews, 5 GP interviews and 5 practice nurse interviews. A prototype of PatientCoach that included modules for coaching, personalised information, asthma self-monitoring, medication treatment plan, feedback, e-consultations and a forum was demonstrated. A semistructured topic guide was used. Directed content analysis was used to analyse data. Reported barriers were classified according to a framework by Grol and Wensing.

RESULTS

A variety of barriers emerged among all participant groups. Barriers identified among patients include a lack of a patient-professional partnership in using PatientCoach and a lack of perceived benefit in improving asthma symptoms. Barriers identified among GPs include a low sense of urgency towards asthma care and current work routines. Practice nurses identified a low level of structured asthma care and a lack of support by colleagues as barriers. Among all participant groups, insufficient ease of use of PatientCoach, lack of financial arrangements and patient characteristics such as a lack of asthma symptoms were reported as barriers.

CONCLUSIONS

We identified a variety of barriers to implementation of PatientCoach. An effective implementation strategy for internet-based self-management support in asthma care should focus on these barriers.

Mapping the Asthma Care Process: Implications for Research and Practice

BACKGROUND

Whether people with asthma gain and maintain control over their condition depends not only on the availability of effective drugs, but also on multiple patient and health care professional (HCP) behaviors. Research in asthma rarely considers how these behaviors interact with each other and drug effectiveness to determine health outcomes, which may limit real-life applicability of findings.

OBJECTIVE

The objective of this study was to develop a logic process model (Asthma Care Model; ACM) that explains how patient and HCP behaviors impact on the asthma care process.

METHODS

Within a European research project on asthma (ASTRO-LAB), we reviewed asthma care guidelines and empirical literature, and conducted qualitative interviews with patients and HCPs. Findings were discussed with the project team and respiratory care experts and integrated in a causal model.

RESULTS

The model outlines a causal sequence of treatment events, from diagnosis and assessment to treatment prescription, drug exposure, and health outcomes. The relationships between these components are moderated by patient behaviors (medication adherence, symptom monitoring, managing triggers, and exacerbations) and HCP behaviors (medical care and self-management support). Modifiable and nonmodifiable behavioral determinants influence the behaviors of patients and HCPs. The model is dynamic as it includes feedback loops of behavioral and clinical outcomes, which influence future patient and HCP decision making. Key evidence for each relationship is summarized to derive research priorities and clinical recommendations.

CONCLUSIONS

The ACM model is of interest to both researchers and practitioners, and intended as a first version (ACM-v1) of a common framework for generating and translating research evidence in asthma care.

Barriers and facilitators to patient recruitment to a cluster randomized controlled trial in primary care: lessons for future trials

Background

Primary-care based randomized controlled trials (RCTs) build an important evidence base for general practice but little evidence exists about barriers to recruitment which often hamper such trials.

We investigated the issues that impeded and facilitated recruitment to a clinical trial in general practice.

Methods

GPs participating in a cluster RCT that tested interventions for improving medication adherence and asthma control completed a survey comprising quantitative and free text questions about their recruitment experiences. We used backward regression to analyze quantitative data and coded free text responses into themes.

Results

40/55 of enrolled GPs recruited patients, but only one-third reached the planned recruitment target (5 patients/GP). In univariate analyses, poor patient recruitment by GPs was significantly associated with longer time to first patient enrolment, GP-perceived poor access to eligible patients and GP working in a practice training medical students. In regression analysis, only the first was significant (p = 0.001); the explained variance of the model was 48%. Themes from free text responses described recruitment barriers at the level of GP (e.g. GPs excluding patients for whom research appeared too challenging), practice (e.g. practice cultures disempowered GPs), patient (e.g. reluctance to change treatment for research) and study (e.g. protocol requirements complicating recruitment). Facilitators included GPs perceiving good support from the research team.

Conclusion

Targeted recruitment support early in the recruitment phase may enhance recruitment rates. Over time, interventions to enhance a general practice research culture are also likely to enhance skills to recruit patients, even for complex interventions. We recommend systematic evaluation of recruitment approaches and outcomes in future RCTs to optimize feasibility and success of these important trials.

Inhaler reminders improve adherence with controller treatment in primary care patients with asthma

BACKGROUND

Poor adherence contributes to uncontrolled asthma. Pragmatic adherence interventions for primary care settings are lacking.

OBJECTIVE

To test the effectiveness of 2 brief general practitioner (GP)-delivered interventions for improving adherence and asthma control.

METHODS

In a 6-month cluster randomized 2 × 2 factorial controlled trial, with GP as unit of cluster, we compared inhaler reminders and feedback (IRF) and/or personalized adherence discussions (PADs) with active usual care alone; all GPs received action plan and inhaler technique training. GPs enrolled patients prescribed combination controller inhalers, with suboptimal Asthma Control Test (ACT) scores (ACT score ≤19). Inhaler monitors recorded fluticasone propionate/salmeterol adherence (covertly for non-IRF groups) and, in IRF groups, provided twice-daily reminders for missed doses, and adherence feedback. PAD GPs received communication training regarding adherence. Outcomes collected every 2 months included ACT scores (primary outcome) and severe exacerbations. Intention-to-treat mixed-model analysis incorporated cluster effect and repeated measures.

RESULTS

A total of 43 GPs enrolled 143 patients with moderate-severe asthma (mean age, 40.3 ± 15.2 years; ACT score, 14.6 ± 3.8; fluticasone propionate dose, 718 ± 470 μg). Over 6 months, adherence was significantly higher in the IRF group than in non-IRF groups (73% ± 26% vs 46% ± 28% of prescribed daily doses; P < .0001), but not between PAD and non-PAD groups. Asthma control improved overall (mean change in ACT score, 4.5 ± 4.9; P < .0001), with no significant difference among groups (P = .14). Severe exacerbations were experienced by 11% of the patients in IRF groups and 28% of the patients in non-IRF groups (P = .013; after adjustment for exacerbation history; P = .06).

CONCLUSIONS

Inhaler reminders offer an effective strategy for improving adherence in primary care compared with a behavioral intervention or usual care, although this may not be reflected in differences in day-to-day asthma control.

Educational intervention for older people with asthma: a randomised controlled trial

OBJECTIVES

To improve the asthma control and adherence to asthma preventer medication of older people using the Patient Asthma Concerns Tool (PACT) to identify and address unmet needs and patient concerns.

METHODS

Community dwelling adults over 55 years, living in Victoria or New South Wales were recruited into a single-blind, parallel design, randomised-controlled trial comparing person-centred education including device technique, versus written information-only education. Fifty-eight participants randomised to the intervention group and 56 to the control completed participation.

OUTCOME MEASURES

asthma control, adherence to preventer medication, asthma related quality of life, asthma exacerbations and written action plan ownership were assessed at baseline, and 3 and 12 months post intervention.

RESULTS

Intervention participants experienced improvements in asthma control, adherence to asthma preventer medication, reduced exacerbations, improved quality of life and an increase in asthma action plan ownership at 3 and 12 months.

CONCLUSION

Asthma outcomes in older people can be significantly improved by delivering tailored education that identifies specific patient concerns and unmet needs.

PRACTICAL IMPLICATIONS

Use of the PACT to identify patient concerns and unmet needs will assist health professionals to improve the health literacy of patients by addressing gaps in their knowledge and perceptions of asthma control.

Asthma action plans and patient satisfaction among women with asthma

BACKGROUND

Asthma action plans (AAPs) are a priority recommendation of the National Asthma Education and Prevention Program and have been shown to positively affect health outcomes. Patient satisfaction is an important clinical outcome, yet little is known about its association with receiving an AAP. This study examined the association between having an AAP and behaviors to keep asthma in control and patient satisfaction with care.

METHODS

The study design was a cross-sectional analysis of baseline data from a randomized trial evaluating a self-management program among 808 women with asthma. Participants reported demographic information, interactions with clinicians, whether they had an AAP and owned a peak flow meter, self-management behaviors, and symptoms.

RESULTS

The mean age of the participants was 48 ±13.6 years, 84% (n= 670) were satisfied with their asthma care, and 48% (n= 383) had a written AAP from their physician. Women not having an AAP were less likely to take asthma medication as prescribed [ x 2 (1) = 13.68, P , .001], to initiate a discussion about asthma with their physicians [ x 2 (1) = 26.35, P < .001], and to own a peak fl ow meter [ x 2 (1) =77.84, P < .001]. Adjusting for asthma control, income, and medical specialty,women who did not have an AAP were more likely to report dissatisfaction with their asthma care (OR, 2.07; 95% CI, 1.35-3.17; P < .001).

CONCLUSIONS

Women without an AAP were less likely to initiate discussions with their physicians,take medications as prescribed, and own a peak fl ow meter to monitor asthma, all considered important self-management behaviors. They were also less satisfied with their care. Not having an AAP may affect interactions between patient and physician and clinical outcomes.

Medication use in Australian children with asthma: user's perspective

BACKGROUND AND OBJECTIVES

Medication use-related issues remain problematic in childhood asthma despite effective treatment strategies and public investment into improved asthma management strategies in industrialized countries. This study aimed to carry out an in-depth exploration of the views of parents/carers and children with asthma on medication use.

METHODS

Semi-structured qualitative interviews were conducted with a purposive convenience sample of children with asthma and their parents recruited from general practices in Sydney. Interviews were tape-recorded, transcribed verbatim, and thematically analyzed.

RESULTS

A total of 52 interviews (26 parents/carers and 26 children with asthma) were conducted. Major themes which emerged from the children's interviews included issues such as self-image, resistance to medication use, and lack of responsibility in medication taking. Parental or carer issues included lack of clear understanding of how medications worked, as well as administration difficulties, cost constraints, and beliefs about medications contrary to quality use.

DISCUSSION

This is one of the few research studies exploring the viewpoint of children with asthma about their medications in Australia. Despite investment in dissemination of professional, targeted evidence-based asthma management strategies in healthcare, there seems to be a lack of depth in terms of what parents understand about their child's asthma. Effective communication about medication usage, especially the inclusion of the child in the consultation to empower them to be involved in their own asthma care, may be the answer.

Asthma in the elderly

As the population increases in age, the diseases of older age will have increasing prevalence and place a greater burden on the health system. Despite asthma being usually considered a disease of younger people, asthma mortality is currently greatest in the over 55 age-group. Symptoms and emergency presentations for health care due to asthma place a great burden on the quality of life of those over age 55 with asthma. Asthma in older people is under-diagnosed due to patient and physiological factors. Medication strategies for asthma have been dominantly derived from younger cohorts so that effective medication strategies have usually not been explored in older people. Older people with asthma are very concerned regarding side effects of medication so that adherence to therapeutic regimes is often poor. In addition physical disability can lead to difficulty in accessing treatment and using inhaler devices. Practical strategies to improve asthma outcomes in older people have been studied infrequently and the goals of self-management suitable for younger age-groups may not be applicable in this group. Consequently, asthma in older people is deserving of further attention both to basic mechanisms of disease, precision in diagnosis and effective therapeutic strategies, including those that involve self-management and device use.

Improving paediatric asthma outcomes in primary health care: a randomised controlled trial

OBJECTIVE

To evaluate the effectiveness of the Practitioner Asthma Communication and Education (PACE) Australia program, an innovative communication and paediatric asthma management program for general practitioners.

DESIGN

Randomised controlled trial.

SETTING

General practices from two regions in metropolitan Sydney.

PARTICIPANTS

150 GPs, who were recruited between 2006 and 2008, and 221 children with asthma in their care.

INTERVENTION

GPs in the intervention group participated in two 3-hour workshops, focusing on communication and education strategies to facilitate quality asthma care.

MAIN OUTCOME MEASURES

Patient outcomes included receipt of a written asthma action plan (WAAP), appropriate medication use, parent days away from work, and child days away from school or child care. GP outcomes included frequency of providing a WAAP and patient education, communication and teaching behaviour, and adherence to national asthma guidelines regarding medication use.

RESULTS

More patients of GPs in the intervention group reported receipt of a WAAP (difference, 15%; 95% CI, 2% to 28%; adjusted P=0.046). In the intervention group, children with infrequent intermittent asthma symptoms had lower use of inhaled corticosteroids (difference, 24%; 95% CI, -43% to -5%; P=0.03) and long-acting bronchodilators (difference, 19%; 95% CI, -34% to -5%; P=0.02). GPs in the intervention group were more confident when communicating with patients (difference 22%; 95% CI, 3% to 40%; P=0.03). A higher proportion of GPs in the intervention group reported providing a WAAP more than 70% of the time (difference, 23%; 95% CI, 11% to 36%; adjusted P=0.002) and prescribing spacer devices more than 90% of the time (difference, 29%; 95% CI, 16% to 42%; adjusted P=0.02).

CONCLUSIONS

The PACE Australia program improved GPs' asthma management practices and led to improvements in some important patient outcomes.

A snapshot of general practitioner attitudes, levels of confidence and self-reported paediatric asthma management practice

The prevalence of asthma in Australia is high. Previous findings have suggested that asthma management, particularly in primary care, remains suboptimal and recent government initiatives to improve asthma management and encourage the use of written asthma action plans (WAAPs) in general practice have been implemented. We aimed to assess the attitudes, confidence and self-reported paediatric asthma management practices of a convenience sample of Australian general practitioners (GPs). A baseline questionnaire was administered to GPs as part of a randomised controlled trial. General practitioners (GPs) were recruited from two areas of greater metropolitan Sydney, NSW between 2006 and 2008. Invitations were sent to an estimated 1200 potentially eligible GPs. Of 150 (12.5%) GPs that enrolled, 122 (10.2%) completed the baseline questionnaire. Though 89% were aware of the Australian National Asthma Guidelines, less than 40% were familiar with guideline recommendations. While 85.2% had positive attitudes towards WAAPs, only 45.1% reported providing them frequently. For children with frequent symptoms, 90% agreed they should prescribe daily, inhaled corticosteroids (ICS), and 83% reported currently prescribing ICS to such patients. These findings indicate gaps between GP attitudes and behaviours and highlights opportunities for interventions to improve paediatric asthma management.

Unmet needs of older people with asthma: cross-sectional survey

INTRODUCTION

Asthma in older people is a major cause of disease burden in Australia and is projected to increase over the next two decades. Current guidelines for asthma care rely predominantly on studies from younger populations.

METHODS

We undertook a cross-sectional survey of older people with asthma to identify their concerns and their perceived asthma symptom burden. One hundred and ninety-nine people over 55 years of age with asthma were recruited from community pharmacies, in the states of Victoria and NSW, Australia.

RESULTS

One-hundred and twenty (62%) participants reported "perfectly" or "very well controlled" asthma over the past month, and 78% claimed adherence to asthma treatment. Despite this, 105 (55%) reported experiencing moderate to severe symptoms and 58 (30%) moderate to extreme restrictions on their lifestyle in the past month. Exacerbations were also common with over one-third of participants seeking emergency asthma care or requiring oral corticosteroids in the past 12 months. In spite of 80% of participants reporting confidence of how to manage their asthma properly, only 10% said they would call an ambulance or visit an Emergency Department if their asthma was "out of control." Further asthma self-management education was considered desirable by two-thirds. However, those over 65 years preferred less autonomy in decision-making compared to those under 65 years. CONCLUSION. Older people with asthma experience a high symptom burden. A simplified version of our questionnaire could assist GPs, specialists, and asthma educators to identify the individual needs of older patients and to tailor their delivery of asthma care accordingly.

Does spirometry training in general practice improve quality and outcomes of asthma care?

OBJECTIVE

Clinical asthma guidelines recommend spirometry for asthma diagnosis, but there is inconsistent evidence about benefits to patients in using it for ongoing management. Our aim was to determine whether training in the use of spirometry for management of asthma provided better health outcomes and improved the quality of care in the primary care setting.

DESIGN

Pragmatic, cluster randomized controlled trial.

SETTING

General practices in two states of Australia.

PARTICIPANTS

Forty practices and 397 adults with asthma.

INTERVENTION

The staff of 26 intervention practices received comprehensive spirometry training. Fourteen control practices provided usual care.

MAIN OUTCOME MEASURES

Primary outcome measures were quality of life, self-reported asthma symptoms and lung function. Secondary measures related to the process of care (e.g. performance of spirometry, preparation of a written asthma action plan) and patient and general practitioner rating of the acceptability and usefulness of spirometry.

RESULTS

There were no statistically significant differences between the groups at 12 months for quality of life (mean difference = -0.23; 95% CI: -0.44, -0.01), days off work (rate ratio = 1.52; 95% CI: 0.91, 2.54), exacerbations (rate ratio = 1.09; 95% CI: 0.85, 1.41), asthma on waking (rate ratio = 1.21; 95% CI: 0.79, 1.85), nocturnal asthma (rate ratio = 0.98; 95% CI: 0.63, 1.51) and post-bronchodilator FEV(1)/FVC ratio (mean difference = -0.01, 95% CI: -0.03, 0.02). There was no improvement in the quality of care provided.

CONCLUSIONS

Training in spirometry did not result in any measurable improvement in the use of spirometry, quality of management of asthma or patient outcomes in primary care.

Nephrologists' perspectives on the effect of guidelines on clinical practice: a semistructured interview study

BACKGROUND

A consistent gap exists between evidence-based guideline recommendations and clinical practice across all medical disciplines, including nephrology. This study aims to explore nephrologists' perspectives on guidelines and elicit their perspectives on the effects of guidelines on clinical decisions.

METHODS

Semistructured face-to-face interviews were undertaken with 19 nephrologists from a variety of clinical settings across Australia. Participants were asked about their views of clinical practice guidelines in nephrology, both local (Caring for Australasians With Renal Impairment [CARI]) and international, and their opinions of other factors that shape their decision making. Interviews were recorded, transcribed, and analyzed qualitatively.

RESULTS

4 major themes were identified. First, overall, the nephrologists interviewed trusted the CARI guideline process and output. Second, guidelines served a variety of purposes, providing a good summary of evidence, a foundation for practice, an educational resource, and justification for funding requests to policy makers, as well as promoting patient adherence to treatment. Third, guidelines were only one input into decision making. Other inputs included individual patient quality of life and circumstances, opinion leaders, peers, nephrologists' own experiences, the regulation and subsidy framework for drugs and devices, policies and work practices of the local unit, and other sources of evidence. Fourth, guideline uptake varied. Factors that favored the use of guidelines included having a strong evidence base, being current, including specific targets and an explicit treatment algorithm, being sent frequent reminders, and having local peer support for implementation and the necessary personnel and other resources for effective implementation.

CONCLUSIONS

Evidence-based guidelines appear to impact strongly on clinical decision making of Australian nephrologists, but are only one input. Improvements in the evidence that underpins guidelines and improvements in the content and formatting of guidelines are likely to make them more influential on decision making. Trust in the guideline groups' processes is a prerequisite for implementation.

Asthma management in rural New South Wales: perceptions of health care professionals and people with asthma

OBJECTIVE

To investigate the perceptions and attitudes towards asthma management of general practitioners, pharmacists and people with asthma in a rural area.

DESIGN

Qualitative semistructured interviews.

SETTING

Small rural centre in New South Wales.

PARTICIPANTS

General practitioners, pharmacists and people with asthma in a rural area.

RESULTS

General practitioners perceived that the patient provided a barrier to the implementation of optimal asthma services. They were aware that other health care professionals had a role in asthma management but were not aware of the details, particularly in relation to that of the pharmacist and would like to improve communication methods. Pharmacists also perceived the patient to be a barrier to the delivery of optimal asthma management services and would like to improve communication with the general practitioner. The impact of the rural environment for the health care professionals included workforce shortages, availability of support services and access to continuing education. People with asthma were satisfied with their asthma management and the service provided by the health care professionals and described the involvement of family members and ambulance officers in their overall asthma management. The rural environment was an issue with regards to distance to the hospital during an emergency.

CONCLUSIONS

General practitioners and pharmacists confirmed their existing roles in asthma management while expressing a desire to improve communication between the two professions to help overcome barriers and optimise the asthma service delivered to the patient. The patient described minimal barriers to optimising asthma management, which might suggest that they might not have great expectations of asthma care.

Improving general practice consultations for older people with asthma: a cluster randomised control trial

OBJECTIVE

To evaluate the effectiveness of a multifaceted educational intervention for general practitioners to improve the outcomes of older people with asthma.

DESIGN

Cluster randomised controlled trial.

PARTICIPANTS AND SETTING

42 GPs recruited from metropolitan Melbourne between 1 August 2006 and 31 July 2007, randomly assigned to an intervention or control group, and 107 patients with asthma, aged 55 years or older (consecutive patients recruited by the GPs).

MAIN OUTCOME MEASURES

Evaluation by means of a videorecorded consultation with a simulated patient for GPs; and for patients, asthma control and quality of life, lung function and action plan ownership at baseline and at 4 months.

RESULTS

GPs in the intervention group scored significantly higher than those in the control group for the content and style of their consultation with simulated patients. At 4 months' follow-up, there was no significant difference between patient groups in the asthma control scores, asthma-related quality of life or lung function.

CONCLUSION

This trial showed an improvement in GPs' performance in delivering asthma care to older people. Despite this, there was no significant improvement in patient outcomes.

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.

Patient-centered education: applying learner-centered concepts to asthma education

OBJECTIVE

To review studies of patient-centered asthma education.

METHOD

CINAHL, Medline, Psycinfo, Eric, PsycARTICLES, and web of science databases were searched. RESULTS Asthma education programs are often based on health behavior theories. Many studies lack rigor in the assessment of the program's efficacy and effectiveness. Asthma education that promotes self-management primarily uses a problem-based approach. Few studies have examined the way educators teach and patients learn. Patient-centered approaches to education have mainly focused on communication between the patient and the health professional. Decision making as part of shared responsibility may vary with every patient. Patient-centered care shares similarities with the Self-Determination Theory as a learner-centered approach to education.

CONCLUSIONS

Many asthma education studies have been completed with varying levels of efficacy and effectiveness reported. Most programs focus on changing behavior with few studies examining educator behavior and/or the patient's learning styles. With a patient-centered approach being the preferred model of care, the incorporation of learner-centered approaches to patient education may prove useful in the future.

Effect of general practitioner education on adherence to antihypertensive drugs: cluster randomised controlled trial

OBJECTIVE

To determine the impact of a simple educational package for general practitioners on adherence to antihypertensive drugs.

DESIGN

Cluster randomised controlled trial.

SETTING

Six randomly selected communities in Karachi, Pakistan.

PARTICIPANTS

200 patients with hypertension taking antihypertensive drugs; 78 general practitioners.

INTERVENTION

Care by general practitioners specially trained in management of hypertension compared with usual care.

MAIN OUTCOME MEASURE

Correct dosing, defined as percentage of prescribed doses taken, measured with electronic medication event monitoring system (MEMS) bottle.

RESULTS

200 patients were enrolled, and 178 (89%) successfully completed six weeks of follow-up. Adherence was significantly greater in the special care group than in the usual care group (unadjusted mean percentage days with correct dose 48.1%, 95% confidence interval 35.8% to 60.4%, versus 32.4%, 22.6% to 42.3%; P=0.048). Adherence was also higher among patients who had higher levels of education (P<0.001), were encouraged by family members (P<0.001), believed in the effect of drugs (P<0.001), and had the purpose of the drugs explained to them (P<0.001).

CONCLUSIONS

Special training of general practitioners in management of hypertension, emphasising good communication between doctors and patients, is more effective than usual care provided in the communities in Karachi. Such simple interventions should be adopted by other developing countries that are now facing an increasing burden of hypertension.

Burden of asthma in the hospital setting: an Australian analysis

OBJECTIVES

This study was designed to report factors associated with asthma hospital admission, such as patient characteristics, type of admission and subsequent outcome i.e. discharge or death, for the years 2000-2005. These data are used for health economic models regarding asthma burden in the hospital setting in Australia.

METHODS

Data was obtained from the Australian Centre for Asthma Monitoring using their amalgamated dataset from all states and territories. Admissions under ICD-10 codes J45 'Asthma' plus all subcodes, and J46 'acute severe asthma' were included. Codes for associated comorbidity at the time of admission were identified, as well as the month of death, age, gender and length and the type of stay. Confidence intervals for death rate assumed a binomial distribution because of the rarity of event.

RESULTS

The total number of all-cause deaths for the 5-year observation period was 289 from 202,739 asthma separations or 0.14% or 143 deaths/100,000 separations and the highest rate was seen in patients over 45 years. Acute upper respiratory tract infections were reported in up to 25% of all asthma hospital admissions. Length of stay was up to a mean average of 10.2 days in patients who died (SD 15.3). In 5 years observation there was 152,758 emergency asthma admissions which contributed greatly to Australian healthcare burden.

CONCLUSIONS

The study demonstrates that emergency admissions dominate asthma care in the hospital setting in Australia, which suggests poor asthma control in some patients with subsequent economic burden. Asthma-related mortality remains a risk for specific patients in the hospital setting.

Identifying modifiable barriers to medication error reporting in the nursing home setting

OBJECTIVES

To have health care professionals in nursing homes identify organizational-level and individual-level modifiable barriers to medication error reporting.

DESIGN

Nominal group technique sessions to identify potential barriers, followed by development and administration of a 20-item cross-sectional mailed survey.

PARTICIPANTS AND SETTING

Representatives of 4 professions (physicians, pharmacists, advanced practitioners, and nurses) from 4 independently owned, nonprofit nursing homes that had an average bed size of 150, were affiliated with an academic medical center, and were located in urban and suburban areas.

MEASUREMENTS

Barriers identified in the nominal group technique sessions were used to design a 20-item survey. Survey respondents used 5-point Likert scales to score factors in terms of their likelihood of posing a barrier ("very unlikely" to "very likely") and their modifiability ("not modifiable" to "very modifiable"). Immediate action factors were identified as factors with mean scores of <3.0 on the likelihood and modifiability scales, and represent barriers that should be addressed to increase medication error reporting frequency.

RESULTS

In 4 nominal group technique sessions, 28 professionals identified factors to include in the survey. The survey was mailed to all 154 professionals in the 4 nursing homes, and 104 (67.5%) responded. Response rates by facility ranged from 55.8% to 92.9%, and rates by profession ranged from 52.0% for physicians to 100.0% for pharmacists. Most respondents (75.0%) were women. Respondents had worked for a mean of 9.8 years in nursing homes and 5.4 years in their current facility. Of 20 survey items, 14 (70%) had scores that categorized them as immediate action factors, 9 (64%) of which were organizational barriers. Of these factors, the 3 considered most modifiable were (1) lack of a readily available medication error reporting system or forms, (2) lack of information on how to report a medication error, and (3) lack of feedback to the reporter or rest of the facility on medication errors that have been reported.

CONCLUSIONS

The study results provide a broad-based perspective of the barriers to medication error reporting in the nursing home setting. Efforts to improve medication error reporting frequency should focus on organizational-level rather than individual-level interventions.

Optimal management of asthma in elderly patients: strategies to improve adherence to recommended interventions

Adherence to asthma medications presents a problem in all age groups, and older people with chronic illnesses such as asthma also have multiple co-morbidities and consequently complex healthcare needs. It has been suggested that older people are also less likely to adhere to medication and treatment than younger people. Although the prevalence of asthma in older people is similar to that of the general population, over two-thirds of those who die from asthma are >50 years of age and there is strong evidence for under-diagnosis. Clinicians therefore face specific challenges in providing healthcare with respect to both asthma diagnosis and treatment in older age groups. Non-adherence to medication can be defined as either 'intentional' or 'unintentional'. Unintentional non-adherence is more likely to be associated with sociodemographic or physical barriers to the use of medication. Intentional non-adherence results from the balance of individual reasoning of risks versus the benefits of taking medication and acceptance of asthma diagnosis. Intentional non-adherence can be addressed through strategies that influence health beliefs and concerns about the adverse effects of medicine. Unintentional adherence can be addressed by assessing and educating the patient in relation to device use and providing education and clear written instructions about medication requirements. However, some barriers to medication use, such as financial ones, may be systematic. Most studies of medication use, efficacy, adverse effects and adherence in patients with asthma primarily involve younger people. Studies of strategies to improve asthma adherence outcomes specifically in older people are urgently needed.
