Empowering family physicians to impart proper inhaler teaching to patients with chronic obstructive pulmonary disease and asthma

An Augmented Reality Technology to Provide Demonstrative Inhaler Technique Education for Patients With Asthma: Interview Study Among Patients, Health Professionals, and Key Community Stakeholders

BACKGROUND

Many people with asthma use incorrect inhaler technique, resulting in suboptimal disease management and increased health service use. Novel ways of delivering appropriate instructions are needed.

OBJECTIVE

This study explored stakeholder perspectives on the potential use of augmented reality (AR) technology to improve asthma inhaler technique education.

METHODS

On the basis of existing evidence and resources, an information poster displaying the images of 22 asthma inhaler devices was developed. Using AR technology via a free smartphone app, the poster launched video demonstrations of correct inhaler technique for each device. In total, 21 semistructured, one-on-one interviews with health professionals, people with asthma, and key community stakeholders were conducted, and data were analyzed thematically using the Triandis model of interpersonal behavior.

RESULTS

A total of 21 participants were recruited into the study, and data saturation was achieved. People with asthma were confident with inhaler technique (mean score 9.17, SD 1.33, out of 10). However, health professionals and key community stakeholders identified that this perception was misguided (mean 7.25, SD 1.39, and mean 4.5, SD 0.71, for health professionals and key community stakeholders, respectively) and facilitates persistent incorrect inhaler use and suboptimal disease management. Delivering inhaler technique education using AR was favored by all participants (21/21, 100%), particularly around ease of use, with the ability to visually display inhaler techniques for each device. There was a strongly held belief that the technology has the capacity for improving inhaler technique across all participant groups (mean 9.25, SD 0.89, for participants; mean 9.83, SD 0.41, for health professionals; and mean 9.5, SD 0.71, for key community stakeholders). However, all participants (21/21, 100%) identified some barriers, particularly regarding access and appropriateness of AR for older people.

CONCLUSIONS

AR technology may be a novel means to address poor inhaler technique among certain cohorts of patients with asthma and serve as a prompt for health professionals to initiate review of inhaler devices. A randomized controlled trial design is needed to evaluate the efficacy of this technology for use in the clinical care setting.

Breath-actuated INhalation TheRapy: survey of phySicians' PErCepTion (INTROSPECT) in Nepal

OBJECTIVE

Breath-actuated inhalers (BAIs) are gaining attention in the management of obstructive airway diseases (OADs). In Nepal, a BAI containing fluticasone propionate/salmeterol (FPS) has been available for a year. This survey is aimed at determining the perception and experience of physicians in Nepal concerning BAIs.

METHODS

A cross-sectional, questionnaire-based survey was conducted. A total of 141 physicians participated and filled the survey.

RESULTS

Most physicians felt that the right device should be easy to teach, learn and remember. They considered coordination and multiple steps as the primary challenges with pressurized metered-dose inhalers and dry powder inhalers, respectively. Most of them agreed that BAIs could address these challenges. BAIs were not only preferred by most of the physicians for asthma and chronic obstructive pulmonary disease but were also the preferred choice in newly diagnosed patients. Physicians believed that if current patients were shifted to BAIs, it could improve inhalation technique (88%) and compliance/adherence (81%). Almost all of them (92-97%) agreed that teaching the breathing technique and the cleaning process was easier and faster in BAIs. BAIs were considered easy and simple to use. Also, BAI's dose-counter helps patients to increase adherence to inhalation therapy.

CONCLUSIONS

In this INTROSPECT survey, physicians in Nepal believed that BAIs could address the key challenges faced with using pMDIs and DPIs in asthma and COPD patients.

Suboptimal Control of Asthma Among Diverse Patients: A US Mixed Methods Focus Group Study

Purpose

The US National Asthma Education and Prevention Program updates and Global Initiative for Asthma report encourage considering the patient perspective to improve asthma control. The objective of the present study was to collect data about the perceptions, experiences, and concerns of adult patients and caregivers of children with asthma regarding rescue, maintenance, and oral corticosteroid treatments.

Patients and Methods

In-person focus groups were conducted in three cities across the US. Participants also completed patient-reported outcome measures assessing asthma control and experiences.

Results

Focus groups were conducted in demographically and clinically diverse adults with asthma (five groups, n=34), caregivers of children with asthma (five groups, n=35), and adults with a dual diagnosis of asthma and chronic obstructive pulmonary disease (one group, n=5). Only 28% of patients were well-controlled by Asthma Control Test/Asthma Control Test-Caregiver Report and 18% by Asthma Impairment and Risk Questionnaire. Forty-four percent of participants reported not following their prescribed medical plan. Four key themes emerged from the focus groups: (1) asthma symptom control and monitoring are often inadequate; (2) treatments are often used incorrectly; (3) communication between health care professionals and patients or caregivers is often ineffective; and (4) concerns related to treatment and desires to improve treatment.

Conclusion

Control of asthma symptoms is suboptimal in the vast majority of patients and both patients and caregivers do not feel sufficiently informed about asthma. Health care providers should be encouraged to engage patients and caregivers in shared decision making for managing asthma and selecting treatments that integrate patient values, preferences, and lifestyles.

Exploring General Practitioners' Preferences and Experience with Respiratory Inhaler Devices

Introduction

Correct inhaler technique is essential for the optimal delivery of inhaled medicines and the successfully management of respiratory conditions. The general practitioner (GP), the prescriber of inhaled medicines, plays a crucial role in educating patients on inhaler technique. However, in the real-world setting, there are barriers. For the GP, it is time and competence and for the patient, it is their ability to recognise inhaler technique as an issue and their ability to maintain correct inhaler technique over time. This study aimed to determine GPs’ experience, skills and priority placed on inhaler technique and to identify factor(s) associated with inhaler technique competence.

Methods

This cross-sectional observational study design surveyed GPs’ perspectives on inhaler use and preferences for inhaler prescribing within their practice setting. GP inhaler technique was assessed. GPs were recruited through an established network of GP practices. Data collected include (i) practice demographics, (ii) inhaler technique opinions and experience, (iii) inhaler prescribing preferences and (iv) inhaler education history data. Data were analysed descriptively and multivariate logistic regression modelling was used to explore the relationship between outcomes and GPs’ ability to use devices correctly.

Results

A total of 227 GPs completed the inhaler survey. Sixty-three percent of GPs reported receiving previous inhaler education and 73.3% educated or checked their patients’ inhaler technique; 64.5% felt they were somewhat competent in doing so. GPs who reported not demonstrating inhaler technique believed that a pharmacist or a practice nurse would do so. When prescribing new inhaler devices, GPs considered the disease being treated first and then patient’s experience with inhalers; they often already have an inhaler preference and this was related to familiarity and perceived ease of use. For GPs, inhaler competence was not associated with their previous inhaler education or the priority placed on inhaler technique.

Conclusion

GPs do recognise the importance of inhaler technique in respiratory management but their technique can be better supported with regular educational updates to inform them about new inhalers and management practices and to support appropriate inhaler choices for their patients.

The current paradigm for biologic initiation: a mixed-methods exploration of practices, unmet needs, and innovation opportunities in self-injection training

BACKGROUND

Self-injection, particularly of biologics, has become a mainstay of chronic disease management. Despite labeling requirement for healthcare provider (HCP) training, current injection initiation experiences have been shown to be suboptimal. This study characterizes gaps in training and support during initiation and identifies rationales to inform solutions.

METHODS

We enrolled HCPs (n = 18) performing routine biologic initiation and patients (n = 24) currently self-injecting biologics. Participants completed activities through an online, remote ethnography tool. We conducted two focus groups with biologic-naïve patients (n = 5). Data was analyzed using thematic frameworks, Q methodology, and quantitative assessments.

RESULTS

Our results suggest considerable gaps exist. Analysis revealed five common themes that could explain these gaps: 1) minimal biologic-specific professional instruction is provided to HCPs; 2) nuanced injection use-steps are not universally understood; 3) no one stakeholder currently 'owns' training; 4) support offered by HCPs and manufacturers is perceived as biased; and 5) emotional burden is not accounted for.

CONCLUSIONS

Our study suggests optimizing several elements to facilitate successful initiations, including structured sessions, improved HCP injection device knowledge, demo-device practice, and focus on both emotional and mechanical aspects. Aligning these factors has potential to increase patient confidence, reduce burden on HCPs, and improve probability of success on therapy.

Association of Nonmedical Switches in Inhaled Respiratory Medications with Disruptions in Care: A Retrospective Prescription Claims Database Analysis

Introduction

There are limited data on the effects of forced medication switching for a nonmedical reason in patients with obstructive airway conditions. This study evaluated disruption in care resulting from a nonmedical medication switch for patients with asthma and/or chronic obstructive pulmonary disease who previously received the inhaled corticosteroid/long-acting β₂-agonist budesonide/formoterol.

Methods

This retrospective pharmacy benefit prescription claims analysis evaluated Medicare Part D patients who filled a prescription for budesonide/formoterol as their last inhaled corticosteroid/long-acting β₂-agonist in 2016 and were affected by a formulary block of budesonide/formoterol in 2017. Changes to respiratory maintenance therapy, length of gaps in care during which a patient was not in possession of a respiratory controller medication, acute medication use indicative of disease exacerbations, and medication adherence were assessed.

Results

A total of 42,553 patients were included in the analysis. Following the formulary block, 30,016 patients (71%) switched to another controller; 20,628 of these patients (69%) switched to a new inhaled corticosteroid/long-acting β₂-agonist, 7081 (23%) stepped down to a monotherapy, and 2307 (8%) switched to a non-inhaled corticosteroid-containing controller. Despite the formulary block, 22,903 patients (54%) attempted to fill budesonide/formoterol as their first postblock controller, and 6624 patients (16%) attempted to return to budesonide/formoterol after switching to another controller. On average, patients experienced a gap in care of approximately 4 months without a controller medication. Also, 9674 (23%) did not fill any controller over the 1-year postblock period. Of those patients who experienced a gap in care, 14,926 (47%) filled a prescription indicative of a possible exacerbation during the gap period (i.e., oral corticosteroids for patients with asthma and oral corticosteroids and/or antibiotics for patients with chronic obstructive pulmonary disease).

Conclusions

The Medicare Part D formulary block was associated with disruption in the management of patients’ respiratory conditions and may have adversely impacted disease control.

Long-term clinical effects of an inhaler guidance DVD in patients with bronchial asthma

OBJECTIVES

Erroneous use of inhalers is a serious problem. Given the multitude of devices currently available, it can be difficult to convey the correct methods for their efficient use to patients. We previously generated an educational DVD that visually and audibly explains the proper use of all inhaler types available in Japan to provide inhalation guidance to patients. Herein, we report the 1-year follow-up of patients who received or did not receive the DVD guidance.

METHODS

Sixty-nine bronchial asthma patients undergoing outpatient treatment who received inhalation guidance from a pharmacist using a standard package insert were randomly allocated to a DVD group (n=35) or a no-DVD group (n=34). Their current oral or inhalant drug regimens were unchanged. Various parameters were measured 12 months later. Frequencies of aggravation during the 12-month period were also determined.

RESULTS

Compared with the no-DVD group, there were significant improvements in asthma control test scores, forced vital capacity, FEV1, impulse oscillometry, resonant frequency, induced sputum eosinophil count, and FeNO in the DVD group after 12 months. Pulmonary function and inflammation parameters improved significantly with the use of the instructive DVD in addition to the package inserts. The frequency of asthma aggravation significantly decreased in the DVD group during the 12-month study period, likely because inhalation procedures were performed accurately.

CONCLUSIONS

A DVD that provides accurate inhalation guidance enhances the quality of life of asthma patients and has substantial clinical ramifications. Thus, this tool would be beneficial for patients in Japan and worldwide.

Brief Education Improves Proper Metered-Dose Inhaler Use

BACKGROUND

Inhaled β-agonists are the cornerstone of acute treatment for asthma and chronic lung disease. Upon emergency department (ED) discharge, patients optimally receive prescriptions for metered-dose inhalers (MDIs) with instructions on their proper use. Yet prior studies suggest that ED personnel have limited knowledge of proper MDI techniques. It is unclear how effectively brief education will improve this knowledge to enable them to provide adequate patient instructions.

OBJECTIVE

Our aim was to evaluate ED medical personnel's baseline knowledge of MDI use and the utility of brief education on their ability to use MDIs.

METHODS

After providing written consent, a spirometry nurse evaluated emergency physicians and nurses on their ability to properly perform three (open-mouth/two-finger, spacer, and closed-mouth) MDI techniques. The same spirometry nurse then gave a short educational session demonstrating the proper MDI techniques. Two weeks later, the nurse re-evaluated the same personnel on their MDI techniques.

RESULTS

All emergency medical personnel initially performed poorly in demonstrating proper MDI technique, averaging 29.8% steps done correctly. Two weeks after their educational session, they improved greatly, averaging 89.4% steps done correctly.

CONCLUSIONS

This study demonstrated both that ED personnel had poor initial knowledge about MDI techniques and that a brief educational intervention improved most people's ability to use, and presumably to instruct patients/parents in proper use of, MDIs.

Choosing the right inhaler for your asthma or COPD patient

Appropriate selection and correct use of inhalation devices is an integral component in the management of asthma and chronic obstructive pulmonary disease (COPD). It is well known that there are many challenges with the use of inhalers, and no one device suits all patients. Challenges can range from difficulties related to lung disease severity and pulmonary function to physical considerations, including manual dexterity and comorbidities such as arthritis. In terms of device selection and adherence, patient engagement and satisfaction are also important factors to consider. Furthermore, problems with inhaler use can be most evident in children and older patients. Here, we discuss aspects for consideration with commonly used devices, including nebulizers, pressurized metered-dose inhalers, dry powder inhalers, and the soft mist inhaler. As each inhaler offers varying technical properties, a tailored and personalized approach to the selection of the most appropriate device for the patient is highly recommended in order to increase the likelihood of achieving improved disease outcomes and enhance persistence with device adherence. Importantly, education and support is crucial, not only to enable patients to recognize the need for optimal disease management, but also to help them develop good inhaler technique. In addition, health care professionals should also aim to increase their knowledge of the devices they prescribe, and develop systems to ensure that they offer comprehensive support to patients in clinical practice. Considering these aspects, this review discusses potential strategies to help address the challenges of inhaler use in asthma and COPD.

ELLIPTA Dry Powder Versus Metered-Dose Inhalers in an Optimized Clinical Trial Setting

BACKGROUND

Reduced error rates have been demonstrated with the ELLIPTA inhaler versus other commonly used devices.

OBJECTIVE

This phase IV, randomized, crossover study evaluated correct use of ELLIPTA compared with 2 commonly prescribed metered-dose inhalers (MDIs) in adults with asthma and optimized inhaler technique.

METHODS

The study comprised 2 crossover substudies (ELLIPTA vs MDI-1 and ELLIPTA vs MDI-2). Inhaler use was assessed at the start of each period, following instruction from a health care professional, and after 28 days of use without instruction. Data for each inhaler were pooled within substudies, irrespective of treatment sequence; study objectives were addressed in each substudy. The primary end point, percentage of participants making 0 errors after 28 days of use, was analyzed separately for each substudy using a Mainland-Gart test for each ELLIPTA versus MDI comparison.

RESULTS

Correct use rates after 28 days were higher with ELLIPTA than with MDI-1 and MDI-2 (ELLIPTA vs MDI-1, 96% vs 84%; ELLIPTA vs MDI-2, 98% vs 91%). Among discordant cases, statistically significantly more participants correctly used ELLIPTA but made 1 or more overall error with MDIs than did those who correctly used the MDIs but made 1 or more overall error using ELLIPTA (87% vs 13% in both substudies; P < .001 and P = .007 for ELLIPTA vs MDI-1 and ELLIPTA vs MDI-2, respectively). More participants made multiple device errors with MDIs than with ELLIPTA.

CONCLUSIONS

Inhaler technique can be optimized in trial settings. In such settings, ELLIPTA is associated with higher rates of correct use and lower error rates than are MDIs.

Correcting inhaler technique decreases severity of obstruction and improves quality of life among patients with obstructive airway disease

Background

Asthma and chronic obstructive lung disease (COPD) together constitute a huge burden on healthcare all around the world. Treatment of these patients is largely dependent on the way the inhalation devices are used. This study aimed at measuring the impact of rectification of inhalation technique on quality of life and severity of obstruction in patients with asthma and COPD.

Materials and Methods

A total of 45 asthma (partly controlled) and 38 patients with COPD (categories B and C) were enrolled after applying optimal exclusion criteria. These patients underwent Asthma Control Test (ACT)/COPD Assessment Test (CAT) questionnaire as a measure of quality of life and forced expiratory volume in one second (FEV₁) as a measure of severity of obstruction at 0 and 4 weeks, respectively.

Results

In asthmatics, the mean FEV₁ improved from 2.0 to 2.15 L after 4 weeks of technique correction (P < 0.001). In addition, the mean ACT scores improved from 18.0 to 20.75 (P < 0.001). In patients with COPD, the mean FEV₁ improved slightly from 1.54 to 1.56 L after 4 weeks of technique correction (P = 0.28). In addition, the mean CAT scores improved from 21.86 to 19.83 (P < 0.001).

Conclusion

Demonstration of correct inhalation technique should be an indispensible part of the treatment prescription of patients with obstructive airway disease. This simple and important task can be undertaken at the level of primary care physicians in a community-based setting to improve patient compliance.

Evaluation of inhaler technique and achievement and maintenance of mastery of budesonide/formoterol Spiromax® compared with budesonide/formoterol Turbuhaler® in adult patients with asthma: the Easy Low Instruction Over Time (ELIOT) study

BACKGROUND

Incorrect inhaler technique is a common cause of poor asthma control. This two-phase pragmatic study evaluated inhaler technique mastery and maintenance of mastery with DuoResp® (budesonide-formoterol [BF]) Spiromax® compared with Symbicort® (BF) Turbuhaler® in patients with asthma who were receiving inhaled corticosteroids/long-acting β2-agonists.

METHODS

In the initial cross-sectional phase, patients were randomized to a 6-step training protocol with empty Spiromax and Turbuhaler devices. Patients initially demonstrating ≥1 error with their current device, and then achieving mastery with both Spiromax and Turbuhaler (absence of healthcare professional [HCP]-observed errors), were eligible for the longitudinal phase. In the longitudinal phase, patients were randomized to BF Spiromax or BF Turbuhaler. Co-primary endpoints were the proportions of patients achieving device mastery after three training steps and maintaining device mastery (defined as the absence of HCP-observed errors after 12 weeks of use). Secondary endpoints included device preference, handling error frequency, asthma control, and safety. Exploratory endpoints included assessment of device mastery by an independent external expert reviewing video recordings of a subset of patients.

RESULTS

Four hundred ninety-three patients participated in the cross-sectional phase, and 395 patients in the longitudinal phase. In the cross-sectional phase, more patients achieved device mastery after three training steps with Spiromax (94%) versus Turbuhaler (87%) (odds ratio [OR] 3.77 [95% confidence interval (CI) 2.05-6.95], p < 0.001). Longitudinal phase data indicated that the odds of maintaining inhaler mastery at 12 weeks were not statistically significantly different (OR 1.26 [95% CI 0.80-1.98], p = 0.316). Asthma control improved in both groups with no significant difference between groups (OR 0.11 [95% CI -0.09-0.30]). An exploratory analysis indicated that the odds of maintaining independent expert-verified device mastery were significantly higher for patients using Spiromax versus Turbuhaler (OR 2.11 [95% CI 1.25-3.54]).

CONCLUSIONS

In the cross-sectional phase, a significantly greater proportion of patients using Spiromax versus Turbuhaler achieved device mastery; in the longitudinal phase, the proportion of patients maintaining device mastery with Spiromax versus Turbuhaler was similar. An exploratory independent expert-verified analysis found Spiromax was associated with higher levels of device mastery after 12 weeks. Asthma control was improved by treatment with both BF Spiromax and BF Turbuhaler.

Multiprofessional COPD care in Austria-challenges and approaches : Results of a qualitative study

Background

Chronic obstructive pulmonary disease (COPD) is a frequent disease of the lungs. Its prevalence was estimated to be 26% in the Global Initiative for Chronic Obstructive Lung Disease (GOLD) I and 11% for GOLD II–IV in Austria. Globally, it ranks third in mortality rate. The particular challenge is that care for these patients falls short due to the lack of structured integrated care. The aim was to assess the current status of multiprofessional COPD care in Austria and identify gaps and potentials.

Methods

We conducted guided focus group interviews between March and July 2016 addressing current COPD care and treatment gaps with the following professional and interest groups: general practitioners, nurses, patients, pharmacists, physiotherapists and pulmonologists. We interviewed 23 patients and 27 healthcare professionals. The interviews were transcribed verbatim and coded into 12 relevant categories.

Results

There needs to be a shift in thinking from treatment-based care to prevention. Patients, just like healthcare professionals, need periodic updates and comprehensive information on this disease. Creating internet platforms with useful information for COPD patients and solving the data privacy issues of the Austrian electronic medical record (ELGA) are also perceived as viable steps. There is a need and request for healthcare professionals to work as a team with clear COPD management guidelines in the outpatient sector, the establishment of outpatient rehabilitation centers as well as creating a new professional profile, the COPD nurse.

Conclusion

Current COPD care needs to be reorganized, particularly in the outpatient sector, to address the needs of patients and healthcare professionals.

Maintenance inhaler preference, attribute importance, and satisfaction in prescribing physicians and patients with asthma, COPD, or asthma-COPD overlap syndrome consulting for routine care

Background

In respiratory disorders, patient- and physician-perceived satisfaction with the maintenance inhaler device is an important factor driving treatment compliance and outcomes. We examine inhaler preferences in asthma and COPD from patient and physician perspectives, particularly focusing on the relative importance of individual device attributes and patient characteristics guiding inhaler choice.

Materials and methods

Real-world data from >7,300 patients with asthma, COPD, or asthma–COPD overlap syndrome (ACOS) consulting for routine care were derived from respiratory Disease Specific Programs conducted in Europe, USA, Japan, and China. Outcome variables included current pattern of inhaled maintenance therapy and device type, physician preference, patient-reported device attribute importance, and satisfaction.

Results

The most commonly prescribed inhalers for maintenance therapy of asthma, COPD, and ACOS were dry powder inhalers (62.8%–88.5% of patients) and pressurized metered dose inhalers (18.9%–35.3% of patients). One-third of physicians stated no preference for maintenance device when prescribing treatment, and less than one-third of patients reported being “extremely satisfied” with any attribute of their device. Instructions being “simple and easy to follow” was the inhaler attribute most commonly selected as important. For approximately one-third of patients across all groups, “ease of use/suitability of inhaler device” was a reason for the prescribing decision, as stated by the physician. Device characteristics were more likely to impact the prescribing decision in older patients (in asthma and COPD; P<0.01) and those with worse disease severity (in COPD; P<0.001).

Conclusion

A relatively high proportion of physicians had no preference for inhaler type across asthma, COPD, and ACOS. Simplicity of use was the most important inhaler attribute from a patient’s perspective. Physicians appeared to place most importance on ease of use and device suitability when selecting inhalers for older patients and those with more severe disease, particularly in COPD.

Inhalation device options for the management of chronic obstructive pulmonary disease

Chronic obstructive pulmonary disease (COPD) is characterized by chronic respiratory symptoms and airflow limitation, resulting from abnormalities in the airway and/or damage to the alveoli. Primary care physicians manage the healthcare of a large proportion of patients with COPD. In addition to determining the most appropriate medication regimen, which usually includes inhaled bronchodilators with or without inhaled corticosteroids, physicians are charged with optimizing inhalation device selection to facilitate effective drug delivery and patient adherence. The large variety of inhalation devices currently available present numerous challenges for physicians that include: (1) gaining knowledge of and proficiency with operating different device classes; (2) identifying the most appropriate inhalation device for the patient; and (3) providing the necessary education and training for patients on device use. This review provides an overview of the inhalation device types currently available in the United States for delivery of COPD medications, including information on their successful operation and respective advantages and disadvantages, factors to consider in matching a device to an individual patient, the need for device training for patients and physicians, and guidance for improving treatment adherence. Finally, the review will discuss established and novel tools and technology that may aid physicians in improving education and promoting better adherence to therapy.

Effectiveness of training patients using DVD in the accurate use of inhalers for the treatment of bronchial asthma

BACKGROUND

Inhalants are the standard treatment for patients with bronchial asthma. Inaccurate inhaler use leads to inadequate therapeutic effects and unnecessary dosage increases. However, it is a challenge for practitioners to master the various devices available and train patients on the accurate use of inhalers. Thus, establishing a system to instruct patients on how to accurately use inhalers is essential. We prepared a DVD and accompanying user manual explaining the operation of each inhaler device used in Japan. This pilot study aimed to examine the efficacy of these materials.

METHODS

The subjects were 33 outpatients with bronchial asthma who received treatment in our facility for asthma and had already received conventional inhalant training. The oral medication and inhalants used by the patients were not changed. The patients were randomly assigned to a DVD viewing group or non-viewing group; various parameters were comparatively examined after 4 weeks.

RESULTS

Significant improvements in Asthma Control Test scores, inhalation technique, forced vital capacity, forced expiratory volume in 1 s, impulse oscillometry resonant frequency, and induced sputum eosinophil count were observed in the DVD viewing group at 4 weeks post training.

CONCLUSIONS

Pulmonary function and inflammatory parameters improved significantly in the DVD viewing group. These findings suggest that unnecessary step-up of asthma treatment can be avoided, leading to treatment cost reduction. Training patients with asthma in accurate inhaler use improves quality of life and therefore has great clinical significance. Hence, this method should be used more extensively in Japan and worldwide.

Inhaler Training Delivered by Internet-Based Home Videoconferencing Improves Technique and Quality of Life

BACKGROUND

COPD is common, and inhaled medications can reduce the risk of exacerbations. Incorrect inhaler use is also common and may lead to worse symptoms and increased exacerbations. We examined whether inhaler training could be delivered using Internet-based home videoconferencing and its effect on inhaler technique, self-efficacy, quality of life, and adherence.

METHODS

In this pre-post pilot study, participants with COPD had 3 monthly Internet-based home videoconference visits with a pharmacist who provided inhaler training using teach-to-goal methodology. Participants completed mailed questionnaires to ascertain COPD severity, self-efficacy, health literacy, quality of life, adherence, and satisfaction with the intervention.

RESULTS

A total of 41 participants completed at least one, and 38 completed all 3 home videoconference visits. During each visit, technique improved for all inhalers, with significant improvements for the albuterol metered-dose inhaler, budesonide/formoterol metered-dose inhaler, and tiotropium dry powder inhaler. Improved technique was sustained for nearly all inhalers at 1 and 2 months. Quality of life measured with the Chronic Respiratory Questionnaire improved following the training: dyspnea (+0.3 points, P = .01), fatigue (+0.6 points, P < .001), emotional function (+0.5 points, P = .001), and mastery (+0.7 points, P < .001). Coping skills measured with the Seattle Obstructive Lung Disease Questionnaire improved (+9.9 points, P = .003). Participants reported increased confidence in inhaler use; for example, mean self-efficacy for using albuterol increased 3 points (P < .001). Inhaler adherence improved significantly after the intervention from 1.6 at the initial visit to 1.1 at month 2 (P = .045). The pharmacist reported technical issues in 64% of visits.

CONCLUSIONS

Inhaler training using teach-to-goal methodology delivered by home videoconference is a promising means to provide training to patients with COPD that can improve technique, quality of life, self-efficacy, and adherence.

A Randomized, Crossover Trial Evaluating Patient Handling, Preference, and Ease of Use of the Fluticasone Propionate/Formoterol Breath-Triggered Inhaler

BACKGROUND

Appropriate inhaler selection is of fundamental importance in obstructive lung disease management. Key factors in device selection include a patient's capacity to operate a particular device and their preference for it.

METHODS

This randomized, open-label, two-period, crossover study (NCT01739387) compared the ability of adolescent and adult patients with obstructive lung disease to correctly handle the fluticasone propionate/formoterol fumarate (FP/FORM; Flutiform^®) pressurized metered-dose inhaler (pMDI) and FP/FORM K-haler^®, a novel breath-triggered inhaler (BTI), following a simple, standardized training regimen. The primary endpoint was the ability to perform all steps correctly at the first attempt. Secondary endpoints included the ability to perform all critical steps correctly at the first attempt, the requisite number of attempts to successfully use the inhaler, the ability to be trained within 15 minutes, and the ability to trigger the K-haler BTI to actuate at the first attempt. Ease of device use and device preference versus patients' usual maintenance inhalers were also assessed.

RESULTS AND CONCLUSIONS

At the first attempt, an identical proportion (77.2% [95% confidence interval [CI]: 72.1, 81.8]) of 307 patients performed all pMDI and K-haler BTI handling steps correctly, whereas the corresponding proportions performing all critical steps correctly were 82.4% (95% CIs: 77.7, 86.5) and 87.0% (95% CI: 82.7, 90.5), respectively. For both devices, >90% of patients required only two attempts to master device usage; >99% of patients could be trained to correctly use each device within 15 minutes. Virtually all patients (99.0% [95% CIs: 97.2, 99.8]) were able to successfully trigger the K-haler BTI's dose-release mechanism at first attempt. Ease of use and preference data for FP/FORM pMDI challenged the perceived wisdom that dry powder inhalers are necessarily simpler to use, whereas the corresponding data for FP/FORM K-haler strongly favored this novel BTI over the Turbuhaler^®, Accuhaler^®, and other pMDIs.

Influence of inhaler technique on asthma and COPD control: a multicenter experience

BACKGROUND

The successful management of asthma and chronic obstructive pulmonary disease (COPD) mostly depends on adherence to inhalation drug therapy, the usage of which is commonly associated with many difficulties in real life. Improvement of patients' adherence to inhalation technique could lead to a better outcome in the treatment of asthma and COPD.

OBJECTIVE

The aim of this study was to assess the utility of inhalation technique in clinical and functional control of asthma and COPD during a 3-month follow-up.

METHODS

A total of 312 patients with asthma or COPD who used dry powder Turbuhaler were enrolled in this observational study. During three visits (once a month), training in seven-step inhalation technique was given and it was practically demonstrated. Correctness of patients' usage of inhaler was assessed in three visits by scoring each of the seven steps during administration of inhaler dose. Assessment of disease control was done at each visit and evaluated as: fully controlled, partially controlled, or uncontrolled. Patients' subjective perception of the simplicity of inhalation technique, disease control, and quality of life were assessed by using specially designed questionnaires.

RESULTS

Significant improvement in inhalation technique was achieved after the third visit compared to the first one, as measured by the seven-step inhaler usage score (5.94 and 6.82, respectively; P<0.001). Improvement of disease control significantly increased from visit 1 to visit 2 (53.9% and 74.5%, respectively; P<0.001) and from visit 2 to visit 3 (74.5% and 77%, respectively; P<0.001). Patients' subjective assessment of symptoms and quality of life significantly improved from visit 1 to visit 3 (P<0.001).

CONCLUSION

Adherence to inhalation therapy is one of the key factors of successful respiratory disease treatment. Therefore, health care professionals should insist on educational programs aimed at improving patients' inhalation technique with different devices, resulting in better long-term disease control and improved quality of life.

Diagnosing COPD: advances in training and practice - a systematic review

Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung syndrome, caused by long-term inhalation of noxious gases and particles, which leads to gradual airflow limitation. All health care professionals who care for COPD patients should have full access to high-quality spirometry testing, as postbronchodilator spirometry constitutes the principal method of COPD diagnosis. One out of four smokers 45 years or older presenting respiratory symptoms in primary care, have non-fully reversible airflow limitation compatible with COPD and are mostly without a known diagnosis. Approximately 50.0%-98.3% of patients are undiagnosed worldwide. The majority of undiagnosed COPD patients are isolated at home, are in nursing or senior-assisted living facilities, or are present in oncology and cardiology clinics as patients with lung cancers and coronary artery disease. At this time, the prevalence and mortality of COPD subjects is increasing, rapidly among women who are more susceptible to risk factors. Since effective management strategies are currently available for all phenotypes of COPD, correctly performed and well-interpreted postbronchodilator spirometry is still an essential component of all approaches used. Simple educational training can substantially improve physicians' knowledge relating to COPD diagnosis. Similarly, a physician inhaler education program can improve attitudes toward inhaler teaching and facilitate its implementation in routine clinical practices. Spirometry combined with inhaled technique education improves the ability of predominantly nonrespiratory physicians to correctly diagnose COPD, to adequately assess its severity, and to increase the percentage of correct COPD treatment used in a real-life setting.
