Impact of a single 10 min education session on asthma control as measured by ACT

Standard patient training versus Vik-Asthme chatbot-guided training: 'AsthmaTrain' - a protocol for a randomised controlled trial for patients with asthma

INTRODUCTION

Therapeutic education for patients with asthma has been shown to reduce asthma morbidity. The high availability of smart phones provides the opportunity to furnish patient training via specifically designed chatbot applications. The goal of this protocol is to perform a first pilot comparison of traditional face to face versus chatbot-guided patient therapeutic education programmes for patients with asthma.

METHODS AND ANALYSIS

Eighty adult patients with a physician-confirmed diagnosis of asthma will be enrolled in a two-parallel-arm, randomised (1:1) controlled pilot trial. A single-Zelen consent procedure is deployed to first enrol all participants in the comparator arm, that is, the standard patient therapeutic education programme at the University Hospitals of Montpellier, France. This means of patient therapeutic education is based on reoccurring interviews and discussion with qualified nursing staff as per usual care. Following baseline data acquisition, randomisation will be performed. Those patients randomised to the comparator arm will not be informed of the second arm. Those patients randomised to the experimental arm will be proposed access to a specifically designed chatbot (Vik-Asthme) as the second tested means of patient training (refusals continue with standard training, though analysed as intention to treat). The primary outcome is change in the total Asthma Quality of Life Questionnaire score at the end of follow-up (6 months). Secondary outcomes cover asthma control, spirometry, general health status, programme adherence and burden for medical staff, exacerbations and medical resource use (medications, consults, emergency visits, hospitalisation and intensive care).

ETHICS AND DISSEMINATION

This study ('AsthmaTrain' protocol version 4-20220330) has been approved by the Committee for the Protection of Persons Ile-de-France VII on 28 March 2022 (reference number 21.03617.000059). Enrolment began on 24 May 2022. Results will be published in international peer-reviewed journals.

How to Choose the Right Inhaler Using a Patient-Centric Approach?

There are many different inhaler devices and medications on the market for the treatment of asthma and chronic obstructive pulmonary disease, with over 230 drug-delivery system combinations available. However, despite the abundance of effective treatment options, the achieved disease control in clinical practice often remains unsatisfactory. In this context, a key determining factor is the match or mismatch of an inhalation device with the characteristics or needs of an individual patient. Indeed, to date, no ideal device exists that fits all patients, and a personalized approach needs to be considered. Several useful choice-guiding algorithms have been developed in the recent years to improve inhaler–patient matching, but a comprehensive tool that translates the multifactorial complexity of inhalation therapy into a user-friendly algorithm is still lacking. To address this, a multidisciplinary expert panel has developed an evidence-based practical treatment tool that allows a straightforward way of choosing the right inhaler for each patient.

Pulmonary rehabilitation: promising nonpharmacological approach for treating asthma?

PURPOSE OF REVIEW

Asthma is a heterogeneous disease, usually characterized by chronic airway inflammation with a history of respiratory symptoms that vary over time and in intensity, together with variable expiratory airflow limitation. The goal of asthma treatment is to reach symptoms control, reduction in future risk and improvement in quality of life (QoL). Guideline-based pharmacologic therapies and the effect of inhaled steroids and bronchodilators have been widely studied over the past decades. We provide an overview of the available evidence on pulmonary rehabilitation as a nonpharmacologic therapy in asthmatic patients.

RECENT FINDINGS

Recently, some studies have highlighted the promising role of nonpharmacologic therapies in asthma, such as pulmonary rehabilitation demonstrating that a pulmonary rehabilitation programme consisting of exercise training, breathing retraining, educational and psychological support, improve exercise capacity, asthma control and QoL and reduce dyspnea, anxiety, depression and bronchial inflammation at any step of the disease.

SUMMARY

Pulmonary rehabilitation shows positive results on exercise tolerance, respiratory symptoms and QoL in asthmatic patients at any steps of the diseases. However, additional information is required to better characterize rehabilitation programmes in order to improve clinical care in asthma.

Common errors in inhalation therapy: Impact and solutions

OBJECTIVE

Inhalation therapy is one of the key pillars in the treatment of chronic obstructive diseases, such as asthma and COPD (Chronic obstructive pulmonary disease); however, wide number of errors occur with high frequency in the inhalation manoeuvres among these patient. This review discuss the main errors made with inhalation devices, factors associated with poor IT (inhalation technique), their consequences and possible solutions.

DATA SOURCES

To do this, we performed a search of any publications available in PubMed between the years 2000 and 2019, using the key words: asthma, COPD, obstructive lung disease, inhalers, misuse and errors.

STUDY SELECTIONS

After a review of the titles and abstracts by the working group, the articles chosen were considered the most relevant in providing evidence of the problems and establishing solutions in the inhalation treatment of asthma and COPD.

RESULTS

There are several publications that associated the errors in the inhalation technique with a poor prognosis both of asthma and COPD. Most authors generally agree in that a poor IT is associated with poor control of the symptoms.

CONCLUSIONS

It is essential to review the IT in all our patients with asthma and COPD due to the high socio-economic impact that it involves; an effort must be made to homogenise the evaluation of IT, so that it helps to transmit a clear message to the patients, as well as to the health professionals on what is and what is not a correct manoeuvre.

Pulmonary Rehabilitation and Asthma

Asthma is a chronic inflammatory disease characterized by airflow limitation and variable respiratory symptoms. It is characterized by variable symptoms such as cough, wheeze, chest tightness, and shortness of breath which vary in intensity and time. In order to reach a comprehensive approach of disease management, the importance of non-pharmacological treatment in addition to pharmacological therapy has been recently highlighted. Studies have documented that pulmonary rehabilitation has beneficial effects in patients with asthma, at any stage of the disease, improving exercise capacity, asthma control, and quality of life and reducing wheezing, anxiety, depression, and bronchial inflammation. Although several evidences suggest a role of pulmonary rehabilitation in patients with asthma, additional information is required to identify a specific program in order to improve clinical care based on specific patient’s needs.

Patient evaluations of asthma counselling quality in primary health care — a cross-sectional survey

Background

Healthcare staff have a key role in counselling patients. This study describes asthma patients’ evaluations of primary care counselling quality.

Methods

The research applied a cross-sectional study design, with data collected from adult asthma patients (n = 73). Data were analysed by descriptive statistics.

Results

Most of participating patients were women (73%) and over 60 years old (67%). The patients were generally satisfied with the counselling. Subjection to an asthma test (p = 0.009) and smoking (p = 0.019) were found to significantly positively affect patient perceptions of counselling quality. The patients also felt that support services should be covered more (74%). Patients with comprehensive education (p = 0.039) and smokers (p = 0.015) were more likely to be satisfied with the counselling than other patients. Counselling was client-oriented (53%) and most patients reported experiencing positive interactions (92%). Most patients agreed that counselling benefitted adherence to self-care (75%) and health promotion (67%). Moreover, almost all of the patients were satisfied with the staff members’ knowledge and skills (97%). Subjection to an asthma test (p = 0.043), age (p = 0.030), smoking (p = 0.014), and duration of illness (p = 0.002) influenced satisfaction with counselling resources.

Conclusion

The results indicate that counselling benefits asthma patients. Performing an asthma test, as well as considering smoking habits and educational level, can improve patient perceptions of counselling.

Repetitive instructions at short intervals contribute to the improvement of inhalation technique

BACKGROUND

Inhaled medicines are key drugs for the treatment of asthma or chronic obstructive pulmonary disease. However, the variety of inhaler devices and complicated inhalation procedures have created confusion among patients, affecting their correct understanding of inhalation. Recent studies reported that up to 80% of patients made technical errors in inhalation and emphasized the necessity for patient education.

OBJECTIVE

We aimed to assess the importance of inhalation-related instructions and to find clinical factors associated with improvements in the inhalation technique.

METHODS

We conducted a retrospective, single-center study at a regional core hospital in Japan. Physicians and community pharmacists constructed an interactive instruction system and shared a common inhalation procedure manual. Patients who received instructions for the inhalation technique at least 3 times were recruited.

RESULTS

A total of 125 patients were analyzed in this study. The median age was 73 years (interquartile range, 67-80 years). At the second visit, 67 patients (53.6%) failed to correctly perform the technique despite being guided at the first visit. At the third visit, 48.8% of patients made some errors. After excluding 40 patients who were not subjected to analysis, the remaining 85 were divided into "improvement" and "no-improvement" groups. The total improvement rate was 57.6%. The median time interval between consecutive instructions in the "improvement" groups was 84 days, whereas that in the "no-improvement" group was 128 days (p < 0.05, U test). No significant difference in the age, sex, or primary disease was seen between these groups.

CONCLUSION

Repetitive instructions at shorter intervals may be helpful for patients to develop and maintain an improved inhalation technique.

Systematic Assessment of Difficult-to-Treat Asthma: Principles and Perspectives

Difficult-to-treat asthma affects a minority of adults and children with asthma but represents a challenging mix of misdiagnosis, multimorbidity, inadequate self-management, severe airway pathobiology, and treatment complications. Management of these patients extends beyond asthma pharmacotherapy, because multiple other patient-related domains need to be addressed as well. Such complexity can hinder adequate clinical assessment even when performed in specialist practice. Systematic assessment undertaken by specialized multidisciplinary teams brings a broad range of resources to bear on patients with difficult-to-treat asthma. Although the concept of systematic assessment is not new, practices vary considerably and implementation is not universal. Nevertheless, assessment protocols are already in place in several institutions worldwide, and outcomes after such assessments have been highly encouraging. This review discusses the rationale, components, and benefits of systematic assessment, outlining its clinical utility and the available evidence for improved outcomes. It describes a range of service configurations and assessment approaches, drawing examples from severe asthma centers around the world to highlight common essential elements. It also provides a framework for establishing such services and discusses practical considerations for implementation.

A behavioral intervention can decrease asthma exacerbations in older adults

BACKGROUND

Older adults have higher rates of asthma morbidity and mortality compared with younger age groups. Few interventions are tailored to this population.

OBJECTIVE

To evaluate a self-management asthma intervention in older adults.

METHODS

Adults age 55 and older with persistent asthma were enrolled into blinded, randomized controlled trial of a 6-session asthma self-management intervention. This educational intervention was conducted in group sessions and through individual telephone calls. Outcomes including asthma exacerbations (defined as unscheduled office visits, emergency department visits, or hospitalizations for asthma), spirometric values, FeNO, asthma control, asthma quality of life, and asthma self-management were assessed at 3, 6, and 12 months.

RESULTS

One hundred eighty-nine subjects were enrolled, 172 were randomized and received at least 1 treatment dose, and 145 (84%) were analyzed at 12 months. On a modified intent-to-treat analysis, those in the intervention group were less likely to have an asthma exacerbation (26.9% vs 47.1%, P = .01), had a lower asthma exacerbation rate (0.8 vs 1.9, P = .02), had better asthma control (19.9 vs 18.6, P = .08), and had a higher asthma self-management score (8.9 vs 8.4, P = .03). After a mixed-model analysis to control for confounding factors, a decrease in asthma exacerbations (P = .02), as well as a decreased asthma exacerbation rate (P = .04), remained statistically significant, whereas asthma control and self-management did not. No other significant outcome differences were found.

CONCLUSION

A 6-session asthma self-management intervention can successfully decrease asthma exacerbations among older adults.

Use of Symptoms Scores, Spirometry, and Other Pulmonary Function Testing for Asthma Monitoring

Asthma is a global problem affecting millions of people all over the world. Monitoring of asthma both in children and in adulthood is an indispensable tool for the optimal disease management and for the maintenance of clinical stability. To date, several resources are available to assess the asthma control, first is the monitoring of symptoms, both through periodic follow-up visits and through specific quality of life measures addressed to the patient in first person or to parents. Clinical monitoring is not always sufficient to predict the risk of future exacerbations, which is why further instrumental examinations are available including lung function tests, the assessment of bronchial hyper-reactivity and bronchial inflammation. All these tools may help in quantifying the future risk for each patient and therefore they potentially may change the natural history of asthmatic disease. The monitoring of asthma in children as in adults is certainly linked by many aspects, however the asthmatic child is a future asthmatic adult and it is precisely during childhood and adolescence that we should implement all the efforts and strategies to prevent the progression of the disease and the subsequent impairment of lung function. For these reasons, asthma monitoring plays a crucial role and must be particularly close and careful. In this paper, we evaluate several tools currently available for asthma monitoring, focusing on current recommendations emerging from various guidelines and especially on the differences between the monitoring in pediatric age and adulthood.
