Inhaler Technique Research Articles

Clinical profile, inhaler technique, and predictors of inhaler adherence among asthma and COPD patients who attended the outpatient emergency department for acute exacerbation.

Understanding the patients' clinical profile, barriers to optimal inhaler use, and adherence are crucial in achieving the treatment goal for asthma and chronic obstructive pulmonary disease (COPD). This study aimed to assess the inhaler technique and identify the predictors of inhaler adherence among asthma and COPD patients who presented to the Emergency Department (ED). This prospective cross-sectional study recruited patients who presented to the outpatient ED of a tertiary hospital for mild-to-moderate exacerbation from March 2022 to February 2023. Convenience sampling was used in this study. The inhaler techniques and adherence of all subjects were evaluated. Regression analysis was used to identify predictors of inhaler adherence. We recruited 120 subjects with a mean age of 47.8 ± 16.0 and were predominantly asthma patients (n = 85, 70.8%). Most were on regular follow-up (n = 72, 60.0%) and adhered to their inhaler(s) (n = 86, 71.7%). Less than half of the subjects use their inhaler(s) correctly (n = 45, 37.5%). Three predictors of inhaler adherence were identified: regular follow-up (aOR 2.072, p = 0.041), correct inhaler technique (aOR 3.071, p = 0.039), and ability to explain inhalers' mode of action (aOR 10.906, p = 0.031). The high rate of wrong inhaler techniques among asthma and COPD patients is worrisome. Identified predictors of inhaler adherence should be targeted when managing this group of patients. In addition to the exacerbation treatment in the ED, referrals to public primary health clinics for regular follow-ups, evaluation of inhaler techniques, and counseling to enhance patient knowledge are crucial.

Nudge theories and strategies influencing adult health behaviors and outcomes in COPD management: a systematic review

ObjectiveChronic obstructive pulmonary disease (COPD) is a chronic respiratory disease with high prevalence and mortality, and self-management is a key component for better outcomes of COPD. Recently, nudging has shown promising potential in COPD management. In the present study, we conducted a systematic review to collate the list of nudges and identified the variables that influence nudging.MethodsWe undertook a systematic review. We employed database searches and snowballing. Data from selected studies were extracted. The risk of bias was assessed using the Cochrane Effective Practice and Organization of Care risk of bias tool. The study is registered with PROSPERO, CRD42023427051.ResultsWe retrieved 4,022 studies from database searches and 38 studies were included. By snowballing, 5 additional studies were obtained. Nudges were classified into four types: social influence, gamification, reminder, and feedback. Medication adherence, inhalation technique, physical activity, smoking cessation, vaccination administration, exercise capacity, self-efficacy, pulmonary function, clinical symptoms, and quality of life were analyzed as targeted health behaviors and outcomes. We found medication adherence was significantly improved by reminders via mobile applications or text materials, as well as feedback based on devices. Additionally, reminders through text materials greatly enhance inhalation techniques and vaccination in patients.ConclusionThis review demonstrates nudging can improve the health behaviors of patients with COPD and shows great potential for certain outcomes, particularly medication adherence, inhalation techniques, and vaccination. Additionally, the delivery modes, the patient characteristics, and the durations and seasons of interventions may influence the successful nudge-based intervention.Clinical trial registrationThis review has been registered in the international Prospective Registry of Systematic Evaluation (PROSPERO) database (identifier number CRD42023427051).

Pharmacist Interventions for Inhaled Medication Use in Chronic Obstructive Pulmonary Disease (COPD).

Pharmacists are ideally situated and trained to educate and advocate for the proper use of inhaled medications among patients in the community. Proper inhaler technique is an important way to prevent exacerbations and manage the symptoms associated with chronic pulmonary diseases. The American Lung Association estimates almost 6 million people 65 years of age or older had a diagnosis of chronic obstructive pulmonary disease (COPD) in 2020 in the United States. However, published reports have found that less than 20% of older people with COPD use inhalers correctly. As inhalers are the primary route of administration for medications used to treat chronic airway diseases such as COPD, pharmacist-led education can help overcome the widespread lack of knowledge regarding proper inhaler use.

Prediction of Transport and Deposition of Porous Particles in the Respiratory System Using Eulerian-Lagrangian Approach.

Deep lung delivery is crucial for respiratory disease treatment. Although nano and submicron particles exhibited a good deposition efficiency in deep regions of the lung, powder nonuniformity and particle agglomeration reduce their efficiency. Inhalation of porous particles (PPs) can overcome the mentioned challenges due to their larger size and low-density. The present study numerically investigates the deposition and penetration efficiency of orally inhaled PPs. A revised drag coefficient was implemented for PP transport. A realistic mouth-throat to the fifth generation of the lung was reconstructed from CT-scan images. A dilute suspension of uniformly distributed particles was considered at three inhalation flow rates (15, 30, and 45 L/min). Governing equations of the flow field and particle transport are solved using an Eulerian-Lagrangian approach. The results demonstrate that inhaling PPs significantly reduces the total and regional deposition of particles. There was also a critical porosity value under moderate and high inhalation flow rates for large PPs. Below this critical value, PP deposition efficiency substantially decreases. Additionally, it was also found that under low inhalation flow rates, the impact of porosity value is negligible. Almost 95% of the PPs penetrate the lower branches. These findings provide particle engineers and pharmaceutics with profound insight into developing novel inhalation techniques and drug delivery methods for deep lung delivery.

Use of long-acting triple therapy for chronic obstructive pulmonary disease (COPD) in practice: The ELETHON physicians' survey

Gaps in optimal COPD management have been identified in clinical practice, with discrepancies between guideline recommendations and routine care. The reasons for such discrepancies are incompletely understood. The ELETHON survey aimed to identify physicians' attitudes towards general concepts of COPD management and, in particular, initiation of inhaled triple therapies. ELETHON was a nationwide cross-sectional survey with general practitioners (GP) and pulmonary specialists (PS) working in the ambulatory outpatient setting in Germany, using a structured 17-item questionnaire (single or multiple choice questions) addressing the topics of secondary prevention, exacerbation detection, strategies for therapy escalation, choice of inhaled triple therapies and evaluation of treatment benefits. Questionnaires filled by n=2028 GPs and n=371 PS were analyzed. In both groups, secondary prevention was deemed important in COPD care (GP/PS 76.4%/90.6%), with inhalation technique, vaccination status, and appropriate inhaled pharmacotherapy as key components. Activity/rehabilitation was rarely mentioned by GPs (48.3% vs. 84.5%). Exacerbations and symptomatic worsening were the main triggers for therapy escalation, but were not recorded in a structured way. "Hospitalization" and "≥2 ambulatory exacerbations" were mentioned most frequently as thresholds. Neither GPs nor PS measured eosinophils in the majority of patients. Fixed triple combinations were preferred, with availability of different treatment steps in the same device as important decision aid. Treatment success was evaluated by exacerbations, quality of life, symptoms, lung function and rescue medication use, while COPD Assessment Test (CAT) score was rarely used by GPs and PS. The ELETHON survey identified gaps in COPD management in Germany. While secondary prevention is deemed important, escalation of inhaled therapy is undertaken rather late, the reported importance of vaccinations does not match current quota in German COPD patients, and non-pharmacological measures are often unused. Exacerbation and symptom documentation is rather subjective, validated questionnaires and blood eosinophils are of minor relevance. These results provide evidence of barriers and hidden potentials towards optimization of routine ambulatory care for COPD patients in Germany.

Evaluation of asthma control after reinforcement of proper inhaler techniques in a tertiary care center in northern India.

Asthma is an obstructive lung disease with high prevalence. Symptom control in asthma remains poor despite significant advancements in treatment guidelines and inhalational devices. This is often attributed to inadequate patient adherence to the inhaler technique and insufficient education on its long-term use. Through this study, we aimed to assess the impact of reinforcement of proper inhaler technique on asthma symptom control and quality of life. A prospective cohort of 400 asthma patients using dry powder inhalers and metered dose inhalers was recruited in the outpatient clinic of our hospital. At the time of recruitment, the correctness of inhaler technique usage was assessed, and the pre-test Inhaler Technique Score (ITS) was recorded for each patient. Then, a ten-step inhalation technique was taught through demonstration, and the post-test ITS score was recorded again. This was done for each patient at monthly intervals for 3 months. Along with it, two tailored questionnaires, the Asthma Control Test (ACT) and Asthma Quality of Life Questionnaire (AQLQ), were administered at each visit to assess disease control and quality of life. Significant enhancements in inhalation technique were noted from the first to the third visit using the ten-step inhalation usage scores, which improved from 6.91 to 9.87 (out of 10) (p<0.001), paralleled by ACT score increases from 17.06 to 19.37 (out of 25) (p<0.001) from visits one to two, and from 19.37 to 20.52 (out of 25) (p<0.001) from visits two to three, signifying improvement in symptom control. Quality of life similarly improved from 4.45 to 5.12 to 5.45 (out of 7) (p<0.001) across the three visits as assessed by AQLQ. In conclusion, promoting proper inhaler technique through structured education programs is crucial for optimizing long-term asthma management and enhancing patients' quality of life.

Asthmatic status in pediatric practice in patients with mild bronchial asthma

The main principle of the treatment of bronchial asthma is rational basic therapy, with priority appointment of inhaled glucocorticosteroids. The basis of the effectiveness of treatment is determined by the correct choice of the form of drug delivery, training the patient in inhalation skills and constant monitoring of the correct use of the inhaler. The article demonstrates the clinical observation of the formation of asthmatic status in a child with mild bronchial asthma. The deterioration of the condition and severe exacerbation was caused by insufficient intake of basic therapy funds into the respiratory tract due to improper inhalation techniques due to the patient's lack of skills in using an inhaler. At the same time, the patient was not trained and the necessary control over the correctness of the inhalation technique was not carried out at the outpatient stage.

Knowledge of self-management and asthma control among asthma patients attending a polyclinic in Western part of Singapore

BACKGROUND: Self-management is important for asthma control, yet it is unclear whether asthmatic patients have sufficient knowledge to optimally manage their disease. We examined the associations between the knowledge of self-management in adult patients attending a polyclinic in Singapore, sociodemographic factors, and asthma control. MATERIALS AND METHODS: A cross-sectional survey was conducted among adult asthmatic patients in a public primary care clinic (polyclinic) using convenience sampling. A a structured and validated self-administered questionnaire solicited the responses of study participants. Questionnaire comprised three sections: (1) Sociodemographic and asthma-related variables, (2) Modified Asthma Self-Management Questionnaire (ASMQ), and (3) The GINA assessment of asthma control. Participants completed the questionnaire in the clinic waiting area and returned them into a sealed box in the same area. Data were analyzed using SPSS version 29.0. Summary statistics were used to describe the study sample; t-test or analysis of variance (ANOVA), as appropriate, tested the differences in self-management knowledge by sociodemographic characteristics. Logistic regression was used to determine the association between asthma control and self-management knowledge controlling for sociodemographic characteristics. RESULTS: The sample comprised 141 asthma patients; Out of a total of 100 points, the mean ASMQ score was 46.8 (standard deviation 21.7). The scores for the knowledge of self-management of Asthma differed by age, level of education, and having been taught about asthma on bivariate analyses (P &lt; 0.05). Linear regression showed a significant association of asthma self-management knowledge with educational level only. No association was observed between ASMQ scores and asthma control. CONCLUSION: There were gaps in patients’ knowledge about asthma self-management, although they were generally knowledgeable about the inhaler technique. Higher education levels were associated with higher levels of knowledge beyond the effect of age and having been instructed about asthma, suggest that it is crucial that educational programs on asthma are made accessible to patients with lower levels of education. Further research needs to determine whether asthma educational programs targeting the knowledge gaps found in this study can improve knowledge of self-management and asthma control.

Risk factors associated with the incidence of asthma among adolescents in Ukraine

Background. Asthma is a common disease among children and adolescents. The purpose of this study was to describe the detailed characteristics of adolescents with asthma, identify risk factors associated with the development of asthma and to evaluate medical care for patients with asthma. Materials and methods. Asthma patients (n = 80) aged 12 to 18 years from the Allergology Department of the Kyiv City Children’s Clinical Hospital 2, the clinical base of the Department of Pediatrics 2 of the Bogomolets National Medical University, were included in the study. The control group consisted of 120 children without asthma. In the group of interviewed children, asthma was diagnosed based on clinical data and objective measurement of lung function. All children underwent spirometry and skin prick test with aeroallergens. During the clinical examination, weight and height were measured, and body mass index was calculated. The survey was conducted by a research doctor using a Google form. Results. Parents of 80 children with asthma were involved in our survey between September 2023 and May 2024. Asthma occurred more often in boys than in girls: odds ratio (OR) = 7.3 (95% confidence interval (CI) 3.84–14.16, P &lt; 0.0001). 31.25 % respondents reported a history of atopic dermatitis, 26.25 % had atopic dermatitis at the time of the study. Food allergy was detected in 25 % children. 48.75 % children had concomitant allergic rhinitis, of which 33.75 % had seasonal, 15 % had perennial. We found that children living in the city had asthma more often: OR = 7.3 (95% CI 3.26–16.62, P &lt; 0.0001). Having an older sibling was associated with a lower risk of asthma: OR = 3.6 (95% CI 1.86–6.92, P &lt; 0.0001). Also, we found that cat owners were significantly more likely not to have asthma: OR = 7.7 (95% CI 3.96–14.99, P &lt; 0.0001). Such data are most likely related to the refusal to own a cat due to the prevalence of cat allergy among children with asthma or at risk of cat allergy. We have not found a statistically significant difference in the group of children with asthma and in the control group in relation to the exposure to tobacco smoke in the atmosphere (passive smoking): OR = 1.4 (95% CI 0.79–2.59, P &gt; 0.05). Conclusions. Treatment of allergies and atopic conditions should be considered an important component of asthma treatment, which may affect the frequency and severity of the disease. In adolescents and adults, smoking cessation, in particular, as a factor in the impact of passive smoking on a sick child can also significantly reduce the number of hospitalizations. Confirming the diagnosis of asthma, demonstrating good inhaler technique, and emphasizing adherence to preventive therapies such as inhaled glucocorticosteroids can improve asthma control and reduce overreliance on short-acting bronchodilators.

Burden of Asthma Among a Sample of Primary Schoolchildren in Jordan Based on Child and Parental Report.

Asthma is a major health issue with an extensive burden to family and health systems. Different measures were used previously to assess disease burden, including prevalence, school performance, parental perceptions, and cost among others. The purpose of this study was to assess the burden of asthma among schoolchildren using parental and child reports and metered-dose inhaler (MDI) demonstration. A descriptive exploratory design based on parent and child self-reports was employed. Parents of children with asthma completed a questionnaire about asthma management and burden including symptoms and health services use. A sample of children with asthma completed a questionnaire measuring their perception of asthma management at school. An assessment of children's proper use of MDI inhalers was also conducted. The burden of asthma was high in the current sample with the majority of children experiencing symptoms, asthma exacerbations, emergency department (ED) visits, and admission because of their asthma. The majority of participating children also performed incorrect inhaler technique, which reflects uncontrolled asthma and poor management. Parental perception of their child's health compared well with their burden of asthma. The outcomes of this study and previous reports show an alarmingly high burden of asthma. This calls for collaboration between professionals and stakeholders with children and caregivers in planning and implementing care, including improving the school environment.

Improving inhaler technique and adherence in children

Inhalers are an essential part of the management of asthma in children and young people, however, technique and adherence are often poor. It is essential to improve these through adequate education and training. This article looks at possible reasons behind errors in inhaler use and strategies health professionals can put in place to remedy these, including repeated education, using multiple training formats, and patient involvement.

A study on physicians' knowledge and practices of asthma managementin Angola.

Asthma is the most common chronic non-communicable disease in children and one of the most common in adults, and the majority of asthma-related deaths are attributed to middle- and low-income countries. Physicians' knowledge and practice have been recognized as fundamental elements in the approach to the asthmatic patient with an impact on the treatment and control of the disease. This study aimed to assess the knowledge and practice of Angolan physicians in the management of asthma, as well as to identify the main gaps. It was a cross-sectional study carried out in Angola. The data were collected through an online questionnaire to assess the knowledge about asthma among the physicians and the Physicians Practice Assessment Questionnaire. Categorical variables were described with frequencies and percentages. All associations between good practice and possible predictors were established with logistic regression analysis. P<0.05 was considered statistically significant. A total of 204 physicians throughout Angola participated; the majority of whom were female, aged -between 31 and 40, and from the Luanda province. The average percentage of correct answers for all domains was 65.8% (±SD11.1%). The lowest percentages were in the answers about the diagnosis, drugs, and the signs of an asthma attack. Out of the 204 participants, 81.9% of physicians confirmed seeing patients with asthma. The average percentage of them who reported practicing asthma management based on recommended guidelines was 59.8% (±SD27.8%). More than half of the physicians did not achieve that percentage. The lowest percentages of correct answers concerned assessment of the inhaler technique, provision of a written referral for asthma education, and use of the GINA guidelines to assess the patient's asthma control. Concerning the predictors of best practices, our results showed that being a physician of older age and with more work experience, as well as having the category of specialist were significant predictors of adherence to recommended practices for asthma management. The physicians' level of knowledge about asthma was moderate, but there are important practical gaps in asthma management regarding standard guidelines.

Examining factors associated with poor metered-dose inhaler technique in a cohort of bronx patients with uncontrolled asthma

Objective Most studies investigating at-risk groups for poor inhaler technique (PT) have been in adolescents. However, evidence suggests older age correlates with PT. This study aimed to correlate patient characteristics with PT in an adult asthma cohort in the Bronx. Methods We categorized 237 patients with uncontrolled asthma by demonstration of good inhaler technique (GT) (n = 112) or PT (n = 58) at their initial visit. Independent variables included age, sex, ethnicity, language, insurance status, BMI, depression severity, and socioeconomic data. Two logistic regression models were created to assess odds of PT among independent variables at initial visit and odds of improvement in technique at follow-up. Results At the initial visit, patients with PT had a mean age of 53.74 (±13.54) versus 45.12 (±13.26) among those with GT (p= <0.001). The PT group also had a lower percentage of patients with private insurance (52.53% versus 71.15%, p = 0.037). When controlling for language, ethnicity, insurance status, and educational attainment, the odds of PT increased with age (OR, 1.051; CI, 1.017-1.087, p = 0.003) and BMI (OR, 1.065; CI, 1.010-1.123, p = 0.020). Males had lower odds of PT (OR, 0.379; CI, 0.144-0.997; p = 0.049). While insurance status did not affect odds of PT, Medicaid users had lower odds of improving technique (OR, 0.184; CI, 0.040-0.854; p = 0.031). Conclusions At baseline, individuals with PT were younger and more likely to be on a public health insurance plan. Increasing age, increasing BMI, and female sex were associated with higher odds of PT at the baseline visit, but were not associated with improvements in technique.

Asthma management in the digital age.

Asthma affects 25 million people in the United States, and its prevalence is increasing. Access to care and adherence to prescribed asthma-treatment programs remain the principal formidable challenges for asthma management. Telemedicine offers substantial opportunities for improved asthma care of patients across the full range of socioeconomic strata. Ever-improving digital tools for asthma assessment and treatment are key components of telemedicine platforms for asthma management. These include a variety of remote patient-monitoring devices, digital inhaler systems, and mobile-health applications that facilitate ongoing assessment and adherence to treatment protocols. Digital tools for monitoring treatment focus on tracking medication use, inhalation technique, and physiological markers such as peak-flow rate and pulse-oximetry. Telemedicine visits allow for elements of assessment via video, approximating or duplicating many aspects of in-person visits, such as evaluating a patient's general appearance, breathing effort, and cough. Challenges remain in ensuring equitable access to these technologies, especially in rural and low-income areas, and in maintaining patient privacy and data security in digital platforms.

Assessment of Knowledge and Attitude of Asthmatic Patients and Their Caregivers Regarding the Disease Using an Asthma Knowledge Questionnaire in a Tertiary Care Hospital in Chennai.

Introduction Asthma, a significant non-communicable disease impacting all age groups, leads to productivity loss, particularly affecting children and causing disruption within families. This study aims to evaluate the knowledge and attitudes of asthmatic patients and caregivers through questionnaires, focusing on available treatment options. Aims and objectives The study aimed to assess the knowledge and attitudes of asthmatic patients and caregivers at a tertiary care hospital in Chennai, Tamil Nadu, India. Objectives included evaluating asthma knowledge using a questionnaire and assessing attitudes towards the disease and available treatment options. Materials and methods This cross-sectional study, conducted at the Department of Respiratory Medicine, Sree Balaji Medical College & Hospital, Chennai, focused on bronchial asthma patients and their caregivers in the Outpatient Department (OPD) from May 2021 to November 2022. The study included 150 participants selected randomly based on sample size calculations. Data, collected through a proforma, included demographic variables. Participants' knowledge and attitudes toward asthma were assessed using the Asthma Knowledge and Asthma Attitude questionnaires. Exclusion criteria comprised patients with a history of tuberculosis, chronic obstructive pulmonary disease, interstitial lung disease, recent hemoptysis, or evidence of infective exacerbation. Results and discussion Among 150 participants, 44% were females and 56% were males. Asthma knowledge was present in 62.1% of females and 79.8% of males, while 37.9% of females and 20.2% of males lacked understanding. High prevalence rates of breathlessness (89.4% females, 90.5% males), wheezing (92.4% females, 81% males), and cough (77.3% females, 75% males) were noted. The knowledge questionnaire revealed a mean score of 4 out of 8, indicating a moderate understanding with significant gaps. Many lacked knowledge about affected sites, harbored misconceptions about pet contact, and dust exposure, and were uninformed about triggers, symptoms, and treatment. Lack of awareness regarding weather-related exacerbations, smoking effects, and medication purposes was evident. Reluctance towards long-term inhaler use underscored the necessity for comprehensive asthma education among patients and caregivers. Attitude questionnaire scores varied: 17 scored 16, 37 scored 18, 24 scored 19, 35 scored 21, 20 scored 24, and 17 scored 26, averaging 20.6, reflecting generally positive attitudes. The attitude questionnaire, with six questions, highlighted attitudes toward asthma. However, stigma around asthma affecting normal lives (77.3%), fear of lifelong medication use (84%), and embarrassment over public inhaler use (74%) highlighted areas for attitude improvement to enhance therapy compliance and patient outcomes. Conclusion Our study highlights concerns among asthma patients and caregivers, particularly those with limited education, regarding treatment side effects. Issues include apprehensions about inhaler therapy's addictive potential, insufficient awareness of asthma triggers, improper inhaler techniques, reluctance towards long-term inhaler use, and embarrassment over public use of inhalers contributing to the study's complexities.

Uncovering patterns of inhaler technique and reliever use: the value of objective, personalized data from a digital inhaler

Electronic inhalers provide information about patterns of routine inhaler use. During a 12-week study, 360 asthma patients using albuterol Digihaler generated 53,083 inhaler events that were retrospectively analyzed. A total of 41,528 (78%) of the recorded inhalation events were suitable for flow analysis (having a PIF ≥ 18 L/min and <120 L/min). Median PIF, inhalation volume, inhalation duration, and time to PIF for these events steadily decreased between the first and last 10 days of the study, by 5.1%, 12.6%, 15.9%, and 6.4%, respectively. Continuous short-acting beta2-agonist (SABA) overuse, defined as ≥2 SABA inhalations/week throughout the study period, was seen in 29% (n = 104) of patients. Of 260 patients with ≥1 instance of acute short-term SABA overuse, 55 (21%) had a confirmed exacerbation. Electronic recording of real-life inhaler use can capture valuable, objective information that could inform disease management and clinical decision-making.

Inhalational Drug Devices: Revisiting the Linchpin of Asthma Management.

Asthma remains a prevalent condition among all age groups globally. First-line treatment requires the delivery of medications into the distal respiratory tract via inhalers. Using appropriate inhaler techniques is a significant challenge in achieving disease control. A variety of inhalers are available for treating asthma, and selecting the appropriate inhaler type for any given patient is crucial to achieving and maintaining symptomatic control. This review will discuss the anatomy and physiology behind drug delivery via inhalers, the types of inhalers currently available for use, nebulizers, and future directions in the delivery of inhaled medications for asthma.

Exploring Experiences and Asthma Management Among Middle Eastern Arabic-Speaking Migrants and Refugees with Asthma: A Qualitative Study.

Effective asthma management relies on individuals' knowledge, inhaler technique, and perceptions of asthma and medications. Investigating barriers and enablers to optimal asthma management is vital. This research pursues a comprehensive understanding of asthma control, asthma-related experiences, perceptions, inhaler technique, and knowledge among Arabic-speaking Middle Eastern migrants and refugees living in Australia. Furthermore, it aims to explore the factors influencing optimal asthma management within this demographic. This study involved interviews with 17 participants, with nine identified as migrants and eight as refugees. All participants were Arabic-speaking Middle Eastern individuals residing in Australia and diagnosed with asthma. Interviews were thematically analysed, and findings were presented following the guidelines of the consolidated criteria for reporting qualitative research (COREQ). The thematic analysis yielded five key themes: (1) asthma experiences; (2) participant perspectives on asthma; (3) asthma management; (4) asthma health literacy; and (5) strategies to overcome obstacles in asthma management. Some disparities were noted between refugees and migrants in terms of their comprehension and views on asthma, medications use, interactions with healthcare providers, and inhaler technique. Refugees experienced more psychological distress and lacked social support, while migrants were more concerned about long-term medication use and preferred specialised care. This research addresses a knowledge gap concerning asthma control among Middle Eastern immigrants. It provides insights into their beliefs and medication adherence. It underscores the importance of considering the unique characteristics of Middle Eastern migrants and refugees when delivering healthcare interventions to enhance overall health and medication adherence within these populations. To address these differences, the study recommends tailored education, specialised clinics, and culturally relevant asthma management plans to enhance self-management support for both groups. Future studies should explore the impact of modifying beliefs, attitudes, and knowledge regarding medications and asthma to enhance asthma management within this population.

Demographic and Asthma-Related Characteristics of Asthmatics Using Pressurized Metered Dose Inhalers and Dry Powder Inhalers.

Background: Asthma controller medications can be delivered via pressurized metered dose inhaler (pMDI) or dry powder inhaler (DPI) devices. Objective: This study aimed to evaluate the frequency of exacerbations and satisfaction rate with device use in asthmatics using pMDIs or DPIs. Methods: A multicenter, cross-sectional study was conducted in adults who used pMDIs or DPIs with correct inhaler technique and good adherence for asthma treatment. Demographic and asthma-related characteristics of the subjects and data regarding device satisfaction were collected through a face-to-face interview in the outpatient clinic. Rates of pMDI and DPI users and the data were compared between the two groups. Results: The study included 338 patients (mean age: 48.6 ± 14.5 years, 253 [74.9%] women). Among participants, 96 (28.4%) were using pMDI and 242 (71.6%) were using DPI. The age of patients using pMDI were significantly lower compared with DPI users. No significant difference was observed in terms of device satisfaction and clinical outcomes of asthma between pMDI and DPI users with good inhaler technique and good adherence. Conclusion: More asthmatics use DPIs, however, pMDIs are used in younger asthmatic patients. No significant difference in terms of device satisfaction and clinical outcomes of asthma was observed between pMDI and DPI users.

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.
