Strategies for Improving Inhalation Technique in Children: A Narrative Review

Video directly observed therapy to improve inhaler technique among pediatric patients with persistent asthma

OBJECTIVE

To assess the feasibility of at-home video directly observed therapy (vDOT) among pediatric patients with asthma to learn and retain proper inhaler technique.

METHODS

We conducted a randomized pilot study with 22 children with persistent asthma aged 6-11 years who were newly prescribed an asthma controller inhaler. Patients underwent 1:1 randomization into one group receiving standard inhaler education during clinic and another receiving standard education plus vDOT for 30 days. vDOT is a method by which trained professionals observe patients self-administering medications through a virtual platform to monitor adherence and proper medication use. We measured inhaler technique, age-appropriate Asthma Control Test (ACT) score, symptom-free days, and healthcare utilization in both groups at 3 months.

RESULTS

Median inhaler technique accuracy percentage score was 88% (IQR 66, 100) for vDOT participants compared to 75% (IQR 38, 88) for controls (p = 0.11). Technique errors within the vDOT group included inadequate breath-holding (34%), inadequate breathing technique (29%), incorrect/no shaking of inhaler (22%) and failure to rinse mouth (15%). There was no difference between groups in change in ACT score, resource utilization or controller prescription refill rates. In the first 30 days, the median number of days until vDOT participants had no observed technique errors was 10 days (range 0-25).

CONCLUSION

vDOT is a viable technique to provide initial and continual education and real-time feedback on inhaler technique after the initial education provided in clinic.

Pediatric asthma inhaler technique: quality and content analysis of YouTube videos

BACKGROUND

Proper technique for using inhalers is crucial in treating pediatric asthma. YouTube offers a wide range of videos on pediatric inhaler technique, but there is a need to analyze the quality, reliability, and content of these resources.

AIMS

This study aims to analyze the quality, reliability, and content of YouTube videos on pediatric asthma inhaler techniques.

METHODS

The study has a descriptive, retrospective, and cross-sectional design. The research was conducted by searching YouTube using the "Pediatric Metered Dose Inhaler," "Pediatric Accuhaler," and "Pediatric Diskus." The video's popularity was measured using the Video Power Index. The quality and reliability of the videos were evaluated using the modified DISCERN and Global Quality Scale (GQS).

RESULTS

This study analyzed 55 YouTube videos on the pediatric inhaler technique. 19 of the videos were related to the pMDI inhaler with a spacer for tidal breathing, 14 pMDI inhaler with a spacer for single breath, and 22 diskus device. Findings show that videos demonstrating the use of pMDI devices for single breath have more reliable modified DISCERN scores. However, videos related to tidal breathing are more popular than those showing the use of diskus devices and single breath. Based on the checklist for videos on diskus devices, the steps with the highest error rates are 'Check dose counter' at 72.7% and 'Breathe out gently, away from the inhaler' at 63.6%. A moderate correlation was observed between the modified DISCERN score and the GQS.

CONCLUSIONS

While YouTube videos on the pMDI single-breath technique may be useful for pediatric patients and caregivers, it is crucial for them to receive inhaler technique education from their healthcare provider. This study's findings hold great significance for pediatric patients and caregivers, particularly those who rely on YouTube for health-related information.

Promoting knowledge of metered dose inhaler (MDI) usage among pharmacy professional students through a mobile app

INTRODUCTION

Efficient asthma management necessitates optimal usage of metered-dose inhalers (MDIs). As future health professionals, pharmacy students are pivotal in disseminating accurate methodologies for MDI usage. Despite having hands-on experience, there is room to enhance their comprehension, highlighting the need for prompt patient educational interventions.

OBJECTIVE

This study aims to evaluate the effectiveness of a mobile app-assisted educational method in improving pharmacy students' understanding of MDI usage.

METHODS

A pre-experimental study was conducted from March to August 2021 with 45 participants enrolled in the Pharmacist Professional Study Program at the Faculty of Medicine and Health Sciences, Universitas Muhammadiyah Yogyakarta. Using a one-group pretest-post-test design, the study measured the app's impact on students' knowledge and MDI usage skills.

RESULTS

The intervention significantly improved students' scores on a 9-step MDI usage checklist, with increases ranging from 0.10 to 0.50 across verbal and motor components. A Mann-Whitney U test validated these findings, showing a statistically significant p-value of 0.001.

CONCLUSION

The mobile app-assisted educational approach substantially enhanced pharmacy students' proficiency in MDI use. The significant rise in mean scores for the 9-step checklist, along with the notable p-value, supports the effectiveness of this intervention in healthcare education.

School-supervised Asthma Therapy is Associated with Improved Long-Term Asthma Outcomes for Underrepresented Minority Children

Asthma morbidity disproportionately impacts children from low-income and racial/ethnic minority communities. School-supervised asthma therapy improves asthma outcomes for up to 15 months for underrepresented minority children, but little is known about whether these benefits are sustained over time. We examined the frequency of emergency department (ED) visits and hospital admissions for 83 children enrolled in Asthma Link, a school nurse-supervised asthma therapy program serving predominantly underrepresented minority children. We compared outcomes between the year preceding enrollment and years one-four post-enrollment. Compared with the year prior to enrollment, asthma-related ED visits decreased by 67.9% at one year, 59.5% at two years, 70.2% at three years, and 50% at four years post-enrollment (all p-values< 0.005). There were also significant declines in mean numbers of total ED visits, asthma-related hospital admissions, and total hospital admissions. Our results indicate that school nurse-supervised asthma therapy could potentially mitigate racial/ethnic and socioeconomic inequities in childhood asthma.

Real-World Use of Inhaled COPD Medications: the Good, the Bad, the Ugly

Patients with chronic obstructive pulmonary disease (COPD) rely primarily on inhaled medications to control and treat symptoms. Although the medications delivered by inhaler devices are often quite efficacious when delivered to the lung, the real-world effectiveness of these inhaler devices often falls short. Barriers to effective inhaler use include inhaler misuse and cost-related nonadherence. Inhaler misuse can be reduced with appropriate education which leads to improved outcomes. Education can be provided in multiple settings by a wide array of clinicians and clinical team members including pharmacists, respiratory therapists, nurses, physicians, advanced practice nurses, physician assistants, and community health workers, among others. However, despite decades of research and existing effective strategies across settings and types of educators, overall not much progress has been made with respect to effective inhaler technique among populations of patients with COPD in nearly half a century. Similarly, cost-related nonadherence is a long-standing and critical barrier to effective control of COPD, with limited improvements, especially until very recently. This perspective reviews the current promising directions for inhaler-based therapies, ongoing challenges, and critical issues requiring urgent attention.

Pediatric Drug Development: Reviewing Challenges and Opportunities by Tracking Innovative Therapies

The paradigm of pediatric drug development has been evolving in a "carrot-and-stick"-based tactic to address population-specific issues. However, the off-label prescription of adult medicines to pediatric patients remains a feature of clinical practice, which may compromise the age-appropriate evaluation of treatments. Therefore, the United States and the European Pediatric Formulation Initiative have recommended applying nanotechnology-based delivery systems to tackle some of these challenges, particularly applying inorganic, polymeric, and lipid-based nanoparticles. Connected with these, advanced therapy medicinal products (ATMPs) have also been highlighted, with optimistic perspectives for the pediatric population. Despite the results achieved using these innovative therapies, a workforce that congregates pediatric patients and/or caregivers, healthcare stakeholders, drug developers, and physicians continues to be of utmost relevance to promote standardized guidelines for pediatric drug development, enabling a fast lab-to-clinical translation. Therefore, taking into consideration the significance of this topic, this work aims to compile the current landscape of pediatric drug development by (1) outlining the historic regulatory panorama, (2) summarizing the challenges in the development of pediatric drug formulation, and (3) delineating the advantages/disadvantages of using innovative approaches, such as nanomedicines and ATMPs in pediatrics. Moreover, some attention will be given to the role of pharmaceutical technologists and developers in conceiving pediatric medicines.

Recognizing and Tackling Inhaler Technique Decay in Asthma and Chronic Obstructive Pulmonary Disesase (COPD) Clinical Practice

A poor inhaler technique continues to represent a substantial barrier to effective asthma and chronic obstructive pulmonary disease management. It can result in perceived lack of treatment effectiveness even with apparent adherence to a prescribed regimen of inhaled maintenance therapies, potentially resulting in an unnecessary change or escalation of treatment. Many patients are not trained to inhaler mastery in real-world practice; furthermore, even where mastery is initially achieved, an ongoing assessment and education are seldom maintained. In this review, we present an overview of the evidence for deterioration of the inhaler technique over time after training, investigate the factors that contribute to this deterioration, and explore innovative approaches to addressing the problem. We also propose steps forward drawn from the literature and our clinical insights.

Assisting Students With Asthma Inhaler Technique and Knowledge

Proper inhaler use is critical to asthma management, but many children and youth do not use their inhalers correctly. School nurses are ideally positioned and have an important role in assessing the inhaler technique and knowledge regarding its use among students. This article discusses common student errors with inhaler technique, along with knowledge deficits surrounding use of asthma inhalers. A tool for assessing inhaler use is provided, in addition to suggestions for how to assist students with improved inhaler technique. By assessing inhaler technique and knowledge early in the school year, school nurses proactively assist in improved student management of their asthma.

The Use of Puzzles in Inhaler Technique Training

Objective: Inhaled drugs are essential for the treatment of several chronic respiratory diseases. However, patient inhaler techniques are frequently suboptimal; here, educational games may enhance patients' understanding of educational interventions. In addition, patients may practice repetitively, learning in a more relaxed and fun environment. In this study we aimed to compare two methods of inhaler technique training: (1) face-to-face training only and (2) face-to-face training and a subsequent puzzle game.Methods: The participants in group 1 were provided only face-to-face training. In group 2, the participants were given a puzzle after receiving the face-to-face training. Subsequently, the inhaler technique scores of both groups were compared. The chi-squared (χ² ) test was used for categorical variables and the Mann-Whitney U test (non-parametric) or Student's t test (parametric) were employed to compare the numerical variables between the groups.Results: In total, 170 patients with asthma and their parents were included in the study. It was found that the median total scores for the inhaler technique (p < 0.001) and the number of correct users (p < 0.001) were higher in group 2, whereas the inhaler technique error rate in shaking the inhaler tube (p < 0.001) was higher in group 1.Conclusion: The present study revealed that the success rate of correct users and participants' total scores were higher in the puzzle game group. Therefore, a game may help patients to better remember and visualize the steps of the inhaler technique. Our study supports the use of puzzles as real-world applications to teach patients optimal inhaler technique.

Analysis of the Consumption of Drugs Prescribed for the Treatment of Asthma in Belgian Children

(1) Asthma is one of the most common chronic diseases in the world among children. The main purpose of this study was to analyze the consumption of asthma medications in order to investigate asthma in children (2-18 years) and the association with health care consumption; (2) a retrospective study using anonymized administrative data for 2013-2018 from the third largest Belgian health insurer was conducted; (3) in 2018, 12.9% of children received at least one asthma medication and 4.4% received at least two packages with a minimum of 30 days between purchases. Preschool children (2-6 years) were three times more likely to take asthma medication than older children (7-18 years). ICS, in combination or not with LABA, were the most dispensed drugs among children. Children with asthma medications were almost twice as likely to receive antibiotics, more likely to end up in the emergency room, and twice as likely to be hospitalized; (4) most children took ICS, according to the GINA guidelines. High rates of nebulization in young children were observed, despite the recommendation to use an inhaler with a spacing chamber as much as possible. Finally, children who took asthma medications were more likely to end up in the ER or be hospitalized.
