[PMID: 37890639 DOI: 10.1016/j.rmed.2023.107430] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Revised: 10/05/2023] [Accepted: 10/15/2023] [Indexed: 10/29/2023]
Abstract
Many inhaler devices are currently used in clinical practice to deliver medication, with each inhaler device offering different benefits to overcome technique issues. Inhaler technique remains poor, contributing to reduced airway drug deposition and consequently poor disease control. Scoring inhaler technique has been used within research as an outcome measure of inhaler technique assessment, and this systematic review collates and evaluates these scoring methods. The review protocol was prospectively registered in PROSPERO (CRD42020218869). A total of 172 articles were screened with 77 included, and the results presented using narrative synthesis due to the heterogeneity of the study design and data. The most frequently used scoring method awarded one point per step in the inhaler technique checklist and was included in 59/77 (77%) of articles; however limited and varied guidance was provided for score interpretation. Other inhaler technique scoring methods included grading the final inhaler technique score, expressing the total score as a percentage/ratio, deducting points from the final score when errors were made, and weighting steps within the checklist depending on how crucial the step was. Vast heterogeneity in the number of steps and content in the inhaler technique checklists was observed across all device types (range 5-19 steps). Only 4/77 (5%) of the inhaler technique measures had undertaken fundamental steps required in the scale development process for use in real world practice. This review demonstrates the demand for a tool that measures inhaler technique and highlights the current unmet need for one that has undergone validation.

Abstract
Implementing asthma guideline recommendations is challenging in low- and middle-income countries. We aimed to explore healthcare provider (HCP) perspectives on the provision of recommended care. Twenty-six HCPs from six public primary care clinics in a semi-urban district of Malaysia were purposively sampled based on roles and experience. Focus group discussions were guided by a semi-structured interview guide and analysed thematically. HCPs had access to guidelines and training but highlighted multiple infrastructure-related challenges to implementing recommended care. Diagnosis and review of asthma control were hampered by limited access to spirometry and limited asthma control test (ACT) use, respectively. Treatment decisions were limited by poor availability of inhaled combination therapy (ICS/LABA) and free spacer devices. Imposed Ministry of Health programmes involving other non-communicable diseases were prioritised over asthma. Ministerial policies need practical resources and organisational support if quality improvement programmes are to facilitate better management of asthma in public primary care clinics.

Abstract
INTRODUCTION Metered-dose inhalers (MDI) are the most used inhalers worldwide. However, improper MDI techniques remain a significant problem and cause uncontrolled asthma. Studies worldwide have reported that the causes of inefficient inhaler technique are multifactorial. However, this topic has been less well studied in the Asian population. This study aimed to evaluate the MDI technique and associated factors among adults with asthma in a primary care setting in Malaysia. METHOD This was a cross-sectional study with universal sampling conducted between July and October 2017. A total of 146 patients with asthma aged 18 years and older in a primary care clinic in Putrajaya, Malaysia were recruited. Logistic regressions were used for statistical analysis to examine the association between improper MDI techniques and their related factors. RESULTS The majority (83%) of respondents were female with a median age of 37 (IQR = 30.75-49.25) years, and the median duration of asthma of 20 (IQR = 10-30) years. An improper MDI technique was observed in 100 (71.9%) patients. The most frequently missed step was exhaling gently and fully before inhalation (51.4%). Respondents who were not on an MDI preventer (adjusted OR: 2.487, 95% CI: 1.121-5.519, p = 0 .025) or had used an MDI 5 years or fewer (adjusted OR: 3.369, 95% CI: 1.425-7.964, p = 0.006) were more likely to employ an improper MDI technique. CONCLUSION There was a high proportion of improper MDI techniques among patients with asthma. Patients not using an MDI preventer or who had used an MDI less than 5 years were at higher risk of improper MDI technique.

Abstract
BACKGROUND/OBJECTIVES Older patients with asthma or chronic obstructive pulmonary disease (COPD) are particularly susceptible to inhaler technique errors and poor clinical outcomes. Several factors may influence their risk, but most studies are inconsistent and contradictory. We developed a tool for the major predictors of individual risk in these patients. DESIGN, SETTING AND PARTICIPANTS In this multicentre, cross-sectional study, several demographic, socioeconomic and clinical characteristics were collected as potential predictors. Clinical features and inhaler technique performance were the main outcomes. Linear and logistic regression models were set up to identify significant variables. Subgroup analysis was performed according to age, cognitive performance and different types of inhalers. RESULTS We included 130 participants, mean age of 74.4 (± 6.4) years. Mean years of device use were 5.8 (± 7.3). Inhaler errors affected 71.6% (95% CI 64-78.5) and critical mistakes 31.1% (95% CI 24-38.8). There were respiratory comorbidities in 82.3% of participants, and 56.2% had moderate to severe disease. A predictive score of misuse probability was developed for clinical practice, including points attributable to cognitive score, adherence and having received previous education on a placebo device. Other significant variables of individual risk were having respiratory allergies or comorbidities, smoking status, depression and educational level. Worse performance was detected in cognitively impaired patients older than 75 years who were using dry powder inhalers (DPI). Lung function was associated with smoking load, incorrect dose activation and absent end pause after inhalation. CONCLUSIONS Individual risk assessment in older individuals should focus on inhaler technique performance (mainly on dose activation and end pause) and adherence, smoking, respiratory comorbidities and cognitive impairment. Placebo device training provided by doctors seems to best suit these patients.

Abstract
OBJECTIVE Inhaler technique education among non-English speaking patients in the United States is understudied, with communication barriers and language differences serving as important challenges to education. A previous needs assessment at our institution identified an opportunity to improve inhaler education for our Mandarin-speaking population. This pilot study evaluates the feasibility of a multimodal intervention to identify errors in inhaler technique. METHODS Adult Mandarin-speaking subjects with chronic obstructive pulmonary disease or asthma participated in a hospital outpatient clinic inhaler training session that utilized multimedia education. Pre-intervention information on demographics, confidence, and disease control was gathered. Post-intervention, subjects were asked if they would change their inhaler technique and what they found useful. RESULTS On pre-intervention survey, eight of eleven (73%) subjects reported being very or completely confident in their inhaler technique. Following the intervention, seven (88%) of those 8 subjects self-identified errors in their technique. Video and handout were reported to be the most useful materials. CONCLUSION A multimodality inhaler technique education intervention helped self-identify errors in inhaler technique among non-English speaking subjects. Implementation and use of language-targeted educational interventions is feasible in an outpatient clinic setting.

Abstract
OBJECTIVES Correct inhaler technique is essential to optimal clinical outcomes in asthma patients. The study aim was to use real-life data from the iHARP database to determine patient factors associated with the performance of inhaler technique errors associated with poor asthma outcomes (as identified in the Critikal study) in patients with asthma prescribed the Turbuhaler (TH), Metered Dose Inhaler (MDI), and Accuhaler (AH) device. METHODS This was a retrospective cross-sectional study using the iHARP database, a multinational initiative including questionnaires and technique review. Identification of inhaler technique errors specifically associated with poor asthma outcomes was performed by reference to the Critikal study. Multivariable logistic regression was used to identify demographic and clinical factors associated with ≥ 1 of these errors. RESULTS Factors significantly associated with ≥ 1 inhaler technique error and worsening asthma outcomes for the TH cohort include female gender, very poor to average self-assessment of inhaler technique; for the MDI cohort, female gender, secondary education, and current smoking status; and, in the AH cohort, lack of inhaler technique review by a trained healthcare professional in the previous twelve months and very poor to average self-assessment of inhaler technique. CONCLUSIONS Numerous specific patient demographic and clinical factors associated with the performance of these errors have been identified, differing according to device. Inhaler technique error associated with poor asthma outcomes is further widespread across devices. Knowledge of these factors and the frequency of their occurence may assist in optimizing device selection and training.

ALLERGY, ASTHMA & IMMUNOLOGY RESEARCH 2020; 12:454-466. [PMID: 32141259 PMCID: PMC7061154 DOI: 10.4168/aair.2020.12.3.454] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/18/2019] [Revised: 12/19/2019] [Accepted: 12/19/2019] [Indexed: 12/16/2022]
Abstract
Purpose Asthma control in older asthmatics is often less effective, which may be attributed to small airway dysfunction and poor inhalation technique. We compared the efficacy of 2 inhalers (fluticasone propionate/formoterol treatment using a pressurized metered-dose inhaler [p-MDI group] vs. fluticasone propionate/salmeterol treatment using a dry powder inhaler [DPI group]) in older asthmatics. Methods We conducted a 12-week, randomized, open-label, parallel-designed trial in older patients (over 55 years old) with moderate-to-severe asthma, and compared the efficacy and safety for asthma control between the 2 groups. Subgroup analyses on disease duration and air trapping were performed. Clinical parameters, including changes in lung function parameters, inhaler technique and adherence, were compared with monitoring adverse reactions between the 2 groups. Results A total of 68 patients underwent randomization, and 63 (30 in the p-MDI group and 33 in the DPI group) completed this study. The p-MDI group was non-inferior to the DPI group with regard to the rate of well-controlled asthma (53.3% vs. 45.5%, P < 0.001; a predefined non-inferiority limit of 17%). In subgroup analyses, the proportion of patients who did not reach well-controlled asthma in the p-MDI group was non-inferior to that in the DPI group; the difference was 12.7% among those with a longer disease duration (≥ 15 years) and 17.5% among those with higher air-trapping (RV/TLC ≥ 45%), respectively (a predefined non-inferiority limit of 17%, P < 0.001). No significant differences were observed in lung function parameters, inhalation techniques, adherence and adverse reactions between the 2 groups. Conclusion These results suggest that the p-MDI group may be comparable to the DPI group in the management of older asthmatics in aspects of efficacy and safety.

Abstract
BACKGROUND Proper inhaler technique is essential to maximize the benefit of medications and improve asthma outcomes. OBJECTIVE To evaluate newly developed pictogram-incorporated medals and their utility on improving the inhaler techniques in asthmatic patients. METHODS A prospective, an open label, randomized controlled clinical study was conducted in Jordan from November 2016 to November 2017. The recruited patients were randomly allocated into two groups; control and intervention. Both groups were verbally counselled about proper use of their inhaler devices, however, pictogram medals were attached to the inhalers of patients in the intervention group only. Both groups were met at baseline and followed-up after 3 months to evaluate their inhaler techniques using standard checklists. RESULTS Of the 219 patients that were recruited and randomized in our study, 49.8% (n = 109) were allocated in the intervention group and 50.2% (n = 110) were in the control group. Both groups had comparable baseline demographics and clinical data (P > 0.05). Significant differences in the improvement of metered dose inhaler (MDI; p < 0.001) and Turbohaler (p = 0.005) techniques were observed between the two groups at the end of study. Patients who used MDI (OR = 7.06, 95% CI = 3.21-15.56, p < 0.001) and Turbohaler (OR = 5.08, 95% CI = 1.57-16.43, p = 0.007) in the intervention group were 7 and 5 times more likely to have improved inhaler techniques as compared to those in the control group respectively. CONCLUSIONS Educational pharmaceutical pictograms represent an inexpensive and feasible intervention that can positively affect the proper use of inhalers in asthmatic patients.

Abstract
BACKGROUND Many factors affect youth adherence to asthma medications. Better understanding of the relationship between problems reported by youth in using asthma medications, self-efficacy, outcome expectations, and adherence is needed. OBJECTIVE The study examined the relationship between youth and caregiver problems in using asthma medications, asthma management self-efficacy, outcome expectations, and youth- and caregiver-reported adherence to asthma controller medications. METHODS Adolescents with persistent asthma and their caregivers were recruited at 4 pediatric practices. Youth were interviewed after their medical visit while caregivers completed a questionnaire. Multivariable linear regression was used to analyze the data. RESULTS Of 359 participating youth, 319 were on controller medications. Youth reported 60% average adherence, whereas caregivers reported 69%. Youth who reported difficulty using their inhaler correctly and youth who reported difficulty remembering to take their medications were significantly less likely to be adherent. Caregivers who reported that it was hard to remember when to give the asthma medications were significantly less likely to report their child being adherent. Both youth and caregivers with higher outcome expectations were significantly more likely to self-report being adherent. CONCLUSIONS Pharmacists and other health care providers should consider asking youth and caregivers about problems in using asthma medications, self-efficacy in managing asthma, and outcome expectations for following treatment regimens, so that they can help youth overcome difficulties they might have in managing their asthma.

Abstract
BACKGROUND Adherence to asthma and chronic obstructive pulmonary disease (COPD) treatment has been shown to depend on patient-level factors, such as disease severity, and medication-level factors, such as complexity. However, little is known about the impact of prescription charges - a factor at the health care system level. This study used real-life data to investigate whether co-payment affects adherence (implementation and persistence) and disease outcomes in patients with asthma or COPD. METHODS A matched, historical cohort study was carried out using two UK primary care databases. The exposure was co-payment for prescriptions, which is required for most patients in England but not in Scotland. Two comparison cohorts were formed: one comprising patients registered at general practices in England and the other comprising patients registered in Scotland. Patients aged 20-59 years with asthma, or 40-59 years with COPD, who were initiated on fluticasone propionate/salmeterol xinafoate, were included, matched to patients in the opposite cohort, and followed up for 1 year following fluticasone propionate/salmeterol xinafoate initiation. The primary outcome was good adherence, defined as medication possession ratio ≥80%, and was analyzed using conditional logistic regression. Secondary outcomes included exacerbation rate. RESULTS There were 1,640 patients in the payment cohort, ie, England (1,378 patients with asthma and 262 patients with COPD) and 619 patients in the no-payment cohort, ie, Scotland (512 patients with asthma and 107 patients with COPD). The proportion of patients with good adherence was 34.3% and 34.9% in the payment and no-payment cohorts, respectively, across both disease groups. In a multivariable model, no difference in odds of good adherence was found between the cohorts (odds ratio, 1.04; 95% confidence interval, 0.85-1.27). There was also no difference in exacerbation rate. CONCLUSION There was no difference in adherence between matched patients registered in England and Scotland, suggesting that prescription charges do not have an impact on adherence to treatment.

Abstract
BACKGROUND Poor inhaler technique has been linked to poor asthma outcomes. Training can reduce the number of inhaler errors, but it is unknown which errors have the greatest impact on asthma outcomes. OBJECTIVE The CRITical Inhaler mistaKes and Asthma controL study investigated the association between specific inhaler errors and asthma outcomes. METHODS This analysis used data from the iHARP asthma review service-a multicenter cross-sectional study of adults with asthma. The review took place between 2011 and 2014 and captured data from more than 5000 patients on demographic characteristics, asthma symptoms, and inhaler errors observed by purposefully trained health care professionals. People with asthma receiving a fixed-dose combination treatment with inhaled corticosteroids and long-acting beta agonist were categorized by the controller inhaler device they used-dry-powder inhalers or metered-dose inhalers: inhaler errors were analyzed within device cohorts. Error frequency, asthma symptom control, and exacerbation rate were analyzed to identify critical errors. RESULTS This report contains data from 3660 patients. Insufficient inspiratory effort was common (made by 32%-38% of dry-powder inhaler users) and was associated with uncontrolled asthma (adjusted odds ratios [95% CI], 1.30 [1.08-1.57] and 1.56 [1.17-2.07] in those using Turbohaler and Diskus devices, respectively) and increased exacerbation rate. In metered-dose inhaler users, actuation before inhalation (24.9% of patients) was associated with uncontrolled asthma (1.55 [1.11-2.16]). Several more generic and device-specific errors were also identified as critical. CONCLUSIONS Specific inhaler errors have been identified as critical errors, evidenced by frequency and association with asthma outcomes. Asthma management should target inhaler training to reduce key critical errors.

Abstract
OBJECTIVES To ascertain the stakeholders' views and devise recommendations for further stages of the Wearable Sensing and Smart Cloud Computing for Integrated Care to Chronic Obstructive Pulmonary Disease (COPD) Patients with Co-morbidities (WELCOME) system development. This system aims to create a wearable vest to monitor physiological signals for patients concerned incorporating an inhaler adherence monitoring, weight, temperature, blood pressure and glucose metres, and a mobile health application for communication with healthcare professionals (HCPs). DESIGN A study of qualitative data derived from focus groups and semistructured interviews. SETTING 4 participating clinical sites in Greece, the UK, Ireland and the Netherlands. PARTICIPANTS Purposive sampling was used to recruit 32 patients with COPD with heart failure, diabetes, anxiety or depression, 27 informal carers and 23 HCPs from 4 European Union (EU) countries for focus groups and interviews. RESULTS Most patients and HCPs described the WELCOME system as 'brilliant and creative' and felt it gave a sense of safety. Both users and HCPs agreed that the duration and frequency of vest wear should be individualised as should the mobile application functions. The parameters and frequency of monitoring should be personalised using a multidisciplinary approach. A 'traffic light' alert system was proposed by HCPs for abnormal results. Patients were happy to take actions in response. CONCLUSIONS WELCOME stakeholders provided valuable views on the development of the system, which should take into account patient's individual comorbidities, circumstances and concerns. This will enable the development of the individualised system in each member state concerned.

Abstract
INTRODUCTION The number of pulmonary diseases that are effectively treated by aerosolized medicine continues to grow. AREAS COVERED These diseases include chronic obstructive pulmonary disease (COPD), lung inflammatory diseases (e.g., asthma) and pulmonary infections. Dry powder inhalers (DPIs) exhibit many unique advantages that have contributed to the incredible growth in the number of DPI pharmaceutical products. To improve the performance, there are a relatively large number of DPI devices available for different inhalable powder formulations. The relationship between formulation and inhaler device features on performance of the drug-device combination product is critical. Aerosol medicine products are drug-device combination products. Device design and compatibility with the formulation are key drug-device combination product aspects in delivering drugs to the lungs as inhaled powders. In addition to discussing pulmonary diseases, this review discusses DPI devices, respirable powder formulation and their interactions in the context of currently marketed DPI products used in the treatment of COPD, asthma and pulmonary infections. EXPERT OPINION There is a growing line of product options available for patients in choosing inhalers for treatment of respiratory diseases. Looking ahead, combining nanotechnology with optimized DPI formulation and enhancing device design presents a promising future for DPI development.
