Regular (up to 10 puffs 4-hourly) inhaled salbutamol should be prescribed at discharge after an asthma attack: myth or maxim?

Over the past 20 years, the concept of asthma weaning plans on discharge after an attack has crept into common practice, although the precise origin of these plans is unclear. High use of short-acting ß2-agonists (SABAs) may result in tolerance to their bronchodilator effects, thus diminishing their efficacy, particularly when they are most needed at the time of an acute attack. Furthermore, key warning signs of a deterioration in asthma control may be masked and the weaning plan may encourage the over-use and over-reliance on SABAs. Side-effects from over-use may also occur, including lactic acidosis, downregulation of the ß2-adrenoreceptor, increased allergen response and pro-inflammatory effects. The need for asthma education at discharge, a personal asthma action plan and vigilance about prescribing and ensuring adherence to maintenance therapy are definitely important. However, the current authors conclude that the benefit of prescribing regular salbutamol (up to 10 puffs every 4 h) at discharge after an acute asthma attack is a myth, and a very dangerous one.

Key recommendations for primary care from the 2022 Global Initiative for Asthma (GINA) update.

The Global Initiative for Asthma (GINA) was established in 1993 by the World Health Organization and the US National Heart Lung and Blood Institute to improve asthma awareness, prevention and management worldwide. GINA develops and publishes evidence-based, annually updated resources for clinicians. GINA guidance is adopted by national asthma guidelines in many countries, adapted to fit local healthcare systems, practices, and resource availability. GINA is independent of industry, funded by the sale and licensing of its materials. This review summarizes key practical guidance for primary care from the 2022 GINA strategy report. It provides guidance on confirming the diagnosis of asthma using spirometry or peak expiratory flow. GINA recommends that all adults, adolescents and most children with asthma should receive inhaled corticosteroid (ICS)-containing therapy to reduce the risk of severe exacerbations, either taken regularly, or (for adults and adolescents with "mild" asthma) as combination ICS-formoterol taken as needed for symptom relief. For patients with moderate-severe asthma, the preferred regimen is maintenance-and-reliever therapy (MART) with ICS-formoterol. Asthma treatment is not "one size fits all"; GINA recommends individualized assessment, adjustment, and review of treatment. As many patients with difficult-to-treat or severe asthma are not referred early for specialist review, we provide updated guidance for primary care on diagnosis, further investigation, optimization and treatment of severe asthma across secondary and tertiary care. While the GINA strategy has global relevance, we recognize that there are special considerations for its adoption in low- and middle-income countries, particularly the current poor access to inhaled medications.

A2BCD: a concise guide for asthma management.

The management of asthma has changed fundamentally during the past two decades. Precise assessment and phenotyping are now required to establish individually targeted treatment with disease-modifying anti-asthmatic drugs (DMAADs). Patients with asthma are often managed by primary care doctors or non-respiratory specialists in secondary care. However, the implementation of complex asthma guidelines in non-specialised care remains a challenge. There is a need for easy-to-understand, concise guides for general practice. In this Viewpoint, we propose a one-page practical guide for asthma management, titled A2BCD, with four components: dual assessment (A2) of asthma (ie, diagnosis and phenotype, plus asthma control and future risks); basic measures (B; eg, education, self-management skills, regular physical activity, and avoidance of asthma triggers); identification and treatment of comorbidities (C) of asthma (eg, chronic rhinosinusitis, obesity, or sleep apnoea); and phenotype-specific, individually targeted treatment with DMAADs (D), including individual inhalation schemes based on inhaled corticosteroids, leukotriene modifiers, biologics, and allergen immunotherapy.

Is Inhaler Technique Adequately Assessed and Reported in Clinical Trials of Asthma and Chronic Obstructive Pulmonary Disease Therapy? A Systematic Review and Suggested Best Practice Checklist.

BACKGROUND: Inhaled medications are central to treating asthma and chronic obstructive pulmonary disease (COPD), yet critical inhaler technique errors are made by up to 90% of patients. In the clinical research setting, recruitment of subjects with poor inhaler technique may give a false impression of both the benefits and the necessity of add-on treatments such as biologic therapies. OBJECTIVE: To assess the frequency with which inhaler technique is assessed and reliably optimized before and during patient enrollment into randomized controlled trials (RCTs) addressing the efficacy of topical therapy, and the escalation of therapy for asthma and COPD. METHODS: Systematic searches were conducted of PubMed and Embase for RCTs published in the past 10 years involving patients with a diagnosis of asthma or COPD undergoing escalation of baseline inhaled therapy (stepping up, changing, adding, switching, increasing, etc) or the introduction of biologic agents. RESULTS: Searches highlighted 1,014 studies, 118 of which were eligible after the removal of duplicates as well as screening and full text review. Of these, only 14 (11.9%) included accessible information in the methods section or referred to such information in online supplements or protocols concerning assessment of participants' inhaler technique. We therefore developed the proposed Best Practice Inhaler Technique Assessment and Reporting Checklist. CONCLUSIONS: Our study identifies a concerning lack of checking and correcting inhaler technique, or at least reporting that this was undertaken, before enrollment in asthma and COPD RCTs, which may affect the conclusions drawn. Mandating the use of a standardized checklist in RCT protocols and ensuring all published RCTs report checking and correcting inhaler technique before enrollment are important next steps.

Global Initiative for Asthma Strategy 2021. Executive Summary and Rationale for Key Changes.

The Global Initiative for Asthma (GINA) Strategy Report provides clinicians with an annually updated evidence-based strategy for asthma management and prevention, which can be adapted for local circumstances (e.g., medication availability). This article summarizes key recommendations from GINA 2021, and the evidence underpinning recent changes. GINA recommends that asthma in adults and adolescents should not be treated solely with short-acting ß2-agonist (SABA), because of the risks of SABA-only treatment and SABA overuse, and evidence for benefit of inhaled corticosteroids (ICS). Large trials show that as-needed combination ICS-formoterol reduces severe exacerbations by ≥60% in mild asthma compared with SABA alone, with similar exacerbation, symptom, lung function, and inflammatory outcomes as daily ICS plus as-needed SABA. Key changes in GINA 2021 include division of the treatment figure for adults and adolescents into two tracks. Track 1 (preferred) has low-dose ICS-formoterol as the reliever at all steps: as needed only in Steps 1-2 (mild asthma), and with daily maintenance ICS-formoterol (maintenance-and-reliever therapy, "MART") in Steps 3-5. Track 2 (alternative) has as-needed SABA across all steps, plus regular ICS (Step 2) or ICS-long-acting ß2-agonist (Steps 3-5). For adults with moderate-to-severe asthma, GINA makes additional recommendations in Step 5 for add-on long-acting muscarinic antagonists and azithromycin, with add-on biologic therapies for severe asthma. For children 6-11 years, new treatment options are added at Steps 3-4. Across all age groups and levels of severity, regular personalized assessment, treatment of modifiable risk factors, self-management education, skills training, appropriate medication adjustment, and review remain essential to optimize asthma outcomes.

The Global Initiative for Asthma (GINA) Strategy Report provides clinicians with an annually updated evidence-based strategy for asthma management and prevention, which can be adapted for local circumstances (e.g., medication availability). This article summarizes key recommendations from GINA 2021, and the evidence underpinning recent changes. GINA recommends that asthma in adults and adolescents should not be treated solely with short-acting β2-agonist (SABA), because of the risks of SABA-only treatment and SABA overuse, and evidence for benefit of inhaled corticosteroids (ICS). Large trials show that as-needed combination ICS–formoterol reduces severe exacerbations by ≥60% in mild asthma compared with SABA alone, with similar exacerbation, symptom, lung function, and inflammatory outcomes as daily ICS plus as-needed SABA. Key changes in GINA 2021 include division of the treatment figure for adults and adolescents into two tracks. Track 1 (preferred) has low-dose ICS–formoterol as the reliever at all steps: as needed only in Steps 1–2 (mild asthma), and with daily maintenance ICS–formoterol (maintenance-and-reliever therapy, “MART”) in Steps 3–5. Track 2 (alternative) has as-needed SABA across all steps, plus regular ICS (Step 2) or ICS–long-acting β2-agonist (Steps 3–5). For adults with moderate-to-severe asthma, GINA makes additional recommendations in Step 5 for add-on long-acting muscarinic antagonists and azithromycin, with add-on biologic therapies for severe asthma.

El Informe sobre la Estrategia Global para el Manejo y la Prevención del Asma (GINA) proporciona a los clínicos una estrategia basada en la evidencia que se actualiza anualmente para el manejo y la prevención del asma, la cual puede adaptarse a las circunstancias locales (por ejemplo, en cuanto a acceso a medicamentos). Este artículo resume las recomendaciones clave de la GINA 2021 y la evidencia que apoya los cambios recientes. La GINA recomienda que el asma en adultos y adolescentes no se trate con agonistas β2 de acción corta (SABA) en monoterapia, debido a los riesgos que acompañan a la monoterapia con SABA y a su uso excesivo, y a la evidencia que demuestra los beneficios del uso de corticosteroides inhalados (ICS). Diversos ensayos clínicos de gran tamaño muestran que la combinación de ICS-formoterol a demanda reduce el número de exacerbaciones graves en el asma leve en ≥ 60% en comparación con los SABA en monoterapia, presentando también resultados similares en las exacerbaciones, síntomas, función pulmonar y efectos antiinflamatorios que el uso diario de ICS más SABA a demanda. Los cambios clave en la GINA 2021 incluyen la división del algoritmo de tratamiento para adultos y adolescentes en dos vías. La vía 1 (la preferencial) cuenta con ICS–formoterol a dosis bajas como tratamiento de rescate en todos los escalones: a demanda solo en los escalones 1–2 (asma leve), y como tratamiento de mantenimiento diario (control y rescate, MART) en los pasos 3–5. La vía 2 (la alternativa) cuenta con SABA a demanda en todos los escalones, más tratamiento regular con ICS (paso 2) o ICS-Agonista β2 de acción prolongada en los escalones 3–5. Para los adultos con asma moderada a grave, la GINA realiza recomendaciones adicionales en el escalón 5, con el agregado de agonistas muscarínicos de larga duración y azitromicina y de tratamientos biológicos en el asma grave. Para los niños entre seis y 11 años, se han añadido opciones nuevas de tratamiento en los escalones 3 y 4. En todos los grupos de edad y gravedad, sigue siendo esencial una valoración personalizada regular, el tratamiento de los factores de riesgo modificables, la educación para el autocontrol de síntomas, técnicas y habilidades del paciente, el ajuste apropiado de la medicación y las revisiones para optimizar la evolución del asma.

Burden and impact of chronic cough in UK primary care: a dataset analysis.

OBJECTIVE: Chronic cough (CC) is a debilitating respiratory symptom, now increasingly recognised as a discrete disease entity. This study evaluated the burden of CC in a primary care setting. DESIGN: Cross-sectional, retrospective cohort study. SETTING: Discover dataset from North West London, which links coded data from primary and secondary care. The index date depicted CC persisting for ≥8 weeks and was taken as a surrogate for date of CC diagnosis. PARTICIPANTS: Data were extracted for individuals aged ≥18 years with a cough persisting ≥8 weeks or cough remedy prescription, between Jan 2015 and Sep 2019. MAIN OUTCOME MEASURES: Demographic characteristics, comorbidities and service utilisation cost, including investigations performed and treatments prescribed were determined. RESULTS: CC was identified in 43 453 patients from a total cohort of 2 109 430 (2%). Median (IQR) age was 64 years (41-87). Among the cohort, 31% had no recorded comorbidities, 26% had been given a diagnosis of asthma, 17% chronic obstructive pulmonary disease, 12% rhinitis and 15% reflux. Prevalence of CC was greater in women (57%) and highest in the 65-74 year age range. There was an increase in the number of all investigations performed in the 12 months before and after the index date of CC diagnosis, and in particular for primary care chest X-ray and spirometry which increased from 6535 to 12 880 and from 5791 to 8720, respectively. This was accompanied by an increase in CC-associated healthcare utilisation costs. CONCLUSION: One-third of individuals had CC in the absence of associated comorbidities, highlighting the importance of recognising CC as a condition in its own right. Overall outpatient costs increased in the year after the CC index date for all comorbidities, but varied significantly with age. Linked primary-care datasets may enable earlier detection of individuals with CC for specialist clinic referral and targeted treatment.

Risks of poor asthma outcome in 14,405 children and young people in London.

This is a 12-month retrospective data analysis (2018/19) of asthma risk factors in 350 North West London general practices. Fourteen thousand four hundred and five of the 482,029 (40% female) children and young people (CYP) had diagnosed asthma. Exacerbations are as follows: (i) 749 (5%) CYP had 797 hospital admissions; 32 (<1%) had 2-6; (ii) 910 (6%) had 1168 recorded asthma attacks; 170 (1%) had 2-12; (iii) 1485 (10%) had 2123 oral corticosteroid courses; 408 (3%) had 2-11. Excess short-acting bronchodilators were prescribed in over half of the CYP. Of the 10,077 (70%) CYP prescribed inhaled corticosteroid preventers, 7279 (72%) were issued with <4 ICS inhaler prescriptions during the year; these CYP accounted for 11% of the admission spells. In all, 30% of CYP had poor symptom control. At least 10% of the CYP having had recent attacks are at risk and dashboards such as those available in North West London could easily facilitate recognition of risk and optimisation of care.

Understanding Dry Powder Inhalers: Key Technical and Patient Preference Attributes.

Inhalable medications for patients with asthma and chronic obstructive pulmonary disease (COPD) can be confusing even for health care professionals because of the multitude of available devices each with different operating principles. Dry powder inhalers (DPI) are a valuable option for almost all of the patients with asthma or COPD. Based on recorded patient inspiratory profiles, the peak inspiratory flow requirement of 30 L min-1 of high-resistance devices does not usually pose any practical limitations for the patients. Suboptimal adherence and errors in device handling are common and require continuous checking and patient education in order to avoid these pitfalls of all inhalation therapy. The aim of this opinion paper is to describe the working principles of DPIs and to summarise their key properties in order to help prescribing the correct inhaler for each patient.Funding: Orion Pharma.
