Abstract
Inhalation represents the most convenient route for delivering respiratory drugs. Delivery systems showed a huge technological progress and several pocket inhalers had been engineered over the last decades for clinical use. Despite the growing technological efforts aimed to simplify the inhalation procedures and optimize the therapeutic outcomes, the effectiveness of drug inhalation through inhalers still represents a major challenge in respiratory medicine. Patients may actually incur in different types of critical errors when using all inhalers and are not capable to inhale throughout all devices equally well. Therefore, the choice of the most suitable and convenient device to prescribe still is a critical issue in real life. Usability is the only comprehensive parameter consenting the effective and objective assessment of pocket inhalers' performance, and allowing their objective comparison and ranking. Unpredictable discrepancies are in fact easily detectable between inhalers (even belonging to the same class) in terms of Usability, independently of the patient's awareness. The reasons were described and discussed for each class of inhalers presently available. Usability is a multidimensional parameter that is much more multifaceted and complex than usually presumed. Usability takes origin from the integrated, balanced and objective assessment of the role played by several factors from different domains, such as: factors related to patient's beliefs, to patients' behavioural components, to device engineering and to the overall cost. Usability is the key parameter for assessing and optimizing the appropriateness of any inhalation treatment through whatever device. Usability would also represent a key investigational instrument for supporting the future development of -innovative and more performing inhaler devices objectively.

Abstract
AIM Investigate inhalation techniques using different inhalers types and their effect on the course of disease. MATERIALS AND METHODS This cross-sectional study included 110 patients with asthma, chronic obstructive pulmonary disease using the inhaler at least one month. Inhaler errors performed during demonstration were evaluated for each patient and entered in the check-lists. We also collected information about co-morbidities, education, mMRC dyspnea score, rate of exacerbations, and performed spirometry. RESULTS 80.9% of patients used metered-dose inhaler, 20.9% - single-dose and 21.8% - multiple-dose dry powder inhaler, 22.7% - soft-mist inhaler. Inhaler errors were made by 80.9% patients. The mean number of mistakes in metered-dose inhaler use was 2±1.6, single-dose powder inhaler -1.5±1.3, multiple-dose dry powder inhaler - 1.25±1.4, soft-mist inhaler - 0.68±0.7 (р=0.003). Age, diagnosis, duration of disease, education level, inhalers usage by relatives have no influence on the inhalation technique. A number of errors was related to female gender (р=0.007) and usage of more than 2 inhalers (r=0.3, p=0.002), previous instruction about inhalation technique (r=0.3, p=0.001). On the other hand, there were correlations between the number of errors and degree of bronchial obstruction, asthma control, severity of dyspnea by mMRC score, exacerbation rate. CONCLUSION Patients with bronchoobstructive diseases perform many inhaler errors, that substantially influences the severity and course of asthma and chronic obstructive pulmonary disease.

Abstract
Purpose Inadequate inhaler technique and nonadherence to therapy are associated with poorer clinical outcomes in chronic obstructive pulmonary disease (COPD). Shared decision-making (SDM), based on clinical evidence, patient goals and preferences, improves quality of care. This study aims to investigate the initial patients’ choices of inhaler devices in patients with newly-diagnosed COPD after an SDM process. Patients and Methods We conducted a prospective, observational, multi-center study in four hospitals in Taiwan from December 2019 to July 2021. All treatment-naïve patients with newly-diagnosed COPD who were able to use three different inhalers of dual bronchodilators (Respimat®, Ellipta®, and Breezhaler®) in the outpatient setting were enrolled. After an SDM process, every patient was prescribed with one inhaler chosen by him- or herself. Errors of using inhalers were recorded after prescription of the inhaler, and at the follow-up visit a month later. The patients’ adherence, satisfaction score, and willingness to keep the initially chosen inhaler were investigated. Results In 109 enrolled patients, 43, 45, and 21 patients chose Respimat®, Ellipta®, and Breezhaler®, respectively. Patients chose different inhalers had similar rates of critical error on both visits, while the rates greatly decrease on the follow-up visit, no matter which inhaler devices they chose initially. The majority of patients had good adherence (use as the prescription daily, n = 79, 82%), satisfaction (satisfaction score ≥4, n = 70, 73%), and strong willingness to keep the initial inhaler (n = 89, 93%) on the follow-up visit regardless of disease severity and their comorbidities. Conclusion SDM might facilitate inhaler choosing, reduce inhaler errors (versus baseline) with good adherence, satisfaction and strong willingness to keep the initial inhaler in patients with newly-diagnosed COPD.

Evaluation of the Clinical Effectiveness of the Salmeterol/Fluticasone Fixed-Dose Combination Delivered via the Elpenhaler ® Device in Greek Patients with Chronic Obstructive Pulmonary Disease and Comorbidities: The AEOLOS Study. J Pers Med 2021; 11:jpm11111159. [PMID: 34834511 PMCID: PMC8621702 DOI: 10.3390/jpm11111159] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2021] [Revised: 11/02/2021] [Accepted: 11/03/2021] [Indexed: 11/16/2022] Open
Abstract
Background: Chronic Obstructive Pulmonary Disease (COPD) is an inflammatory lung disease characterized by airflow limitation that is not completely reversible. The fixed-dose combination of salmeterol and fluticasone propionate (SFC) has been approved as a treatment for COPD patients with a history of recurrent exacerbations and significant symptoms despite regular bronchodilator therapy. In the present study, we evaluated the change in FEV1, mMRC dyspnea score and satisfaction in COPD patients with at least one comorbidity versus those without comorbidities treated with a fixed-dose SFC via the Elpenhaler® device for 12 months. Methods: A 12-month multicenter prospective, observational study (NCT02978703) was designed. Data were collected during the enrollment visit (V0) and six (V1) and twelve months (V2) after the initiation of treatment with Elpenhaler® SFC. The evaluation of the efficacy of the fixed-dose SFC was performed by assessing the change in lung function and dyspnea as expressed by FEV1 and the mMRC dyspnea scale score in COPD patients with and without comorbidities. Results: In total 1016 patients were enrolled, following usual daily clinical practice. A statistically significant improvement was observed in FEV1 in the total study population between visits V0, V1 and V2, with a change from the baseline at V1 0.15 ± 0.22 L and at V2 0.21 ± 0.25 L (p < 0.0001 for both comparisons). This improvement was exhibited regardless of the COPD severity at the baseline, being more noticeable in GOLD 2020 groups B and C. Similarly, a significant improvement was observed in mMRC dyspnea scale values between successive visits (p < 0.0001). In patients without comorbidities, there was a significant improvement in FEV1 of 0.19 ± 0.24 L at V1 and 0.28 ± 0.27 L at V2 (p < 0.0001 for both comparisons), as well as in the mMRC dyspnea score (p < 0.0001). In patients with at least one comorbidity, a corresponding but smaller improvement in FEV1 was observed (0.11 ± 0.34 L at V1 and 0.20 ± 0.42 L at V2; p < 0.0001 for both comparisons and in the mMRC score (p < 0.0001). In the multiple linear regression analysis BMI, GOLD 2020 groups, mMRC and the presence of comorbidities at the baseline were significant factors for the change of FEV1 between V0 and V2. Conclusions: COPD patients treated for twelve months with SFC via the Elpenhaler® device showed significant improvement in lung function and dyspnea at 6 and 12 months, irrespective of the presence of comorbidities.

Abstract
OBJECTIVE The aims of the survey were to assess first experiences of Swiss COPD patients switching from the disposable to the new reusable Respimat inhaler, and to evaluate physicians´ and patients´ views of the new training material. METHODS Patients with a confirmed diagnosis of COPD using a disposable Respimat inhaler for at least three months were included. Patients´ demographics, COPD stage, current treatment, and comorbidities relevant for the handling of the device were assessed. Further, patients were trained on the reusable Respimat by placebo inhaler, patient brochure, video cards/demo films and SMS reminder service. After at least one cartridge change, patients gave comprehensive feedback on their satisfaction with the reusable Respimat and physicians evaluated the need for re-training. RESULTS 235 patients participated in the survey. Of these, 37% suffered from comorbidities restricting the handling of the Respimat. 216 (92%) patients had a better overall satisfaction with the reusable than with the disposable Respimat. Dose counter (86%), monthly preparation (81%) and daily handling (77%) were also assessed as better by most of the patients. In 80% of cases, the user ability was stated as better than for the disposable Respimat. Less than 15% of the patients required further training. Placebo inhaler was the mostly preferred training material by both, physicians (in 86% of the patients) and patients (75%). In patients with comorbidities affecting inhaler handling, overall satisfaction was also better in 86% of the patients. CONCLUSION The majority of patients were satisfied with the new reusable Respimat device and proper handling could be attained using the provided training material, even in patients with restricting comorbidities.

Abstract
Patients with COPD often have reduced physical activity, which can impair health status. Real-world data can provide valuable information on the health and functional status of patients with COPD treated with tiotropium/olodaterol. AERIAL® (ClinicalTrials.gov NCT03165045) was a German, non-interventional study of patients with COPD receiving treatment with tiotropium/olodaterol under real-world conditions for ∼6 weeks. The primary end-point was the proportion of patients achieving a decrease of ≥0.4 points in Clinical COPD Questionnaire (CCQ) score. The CCQ-4 subdomain was used to assess functional status, and the Physician's Global Evaluation (PGE) scale was used to assess the patients' general condition. Safety was assessed, as well as patient satisfaction and willingness to continue treatment. Out of 1351 screened patients, 1322 were treated and 1140 comprised the full analysis set. The primary end-point was met: 66.3% of patients achieved a ≥0.4-point decrease in overall CCQ score (mean±sd decrease 0.78±0.95). Mean±sd decreases in CCQ symptoms and functional state subdomains were 0.84±1.06 and 0.75±1.05 points, respectively. PGE scores improved. One fatality (not treatment-related) and 23 drug-related adverse events were recorded, most commonly nausea and vertigo. >85% of patients were satisfied/very satisfied with tiotropium/olodaterol overall and with the Respimat® device, both in terms of inhalation and handling. Most patients (95.2%) expressed willingness to continue treatment. Patients with COPD treated with tiotropium/olodaterol via Respimat® in routine clinical practice had clinically relevant improvements in health and functional status compared with baseline.

Abstract
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.

Abstract
PLAIN LANGUAGE SUMMARY Inhalers are often used to treat patients with chronic obstructive pulmonary disease (COPD). However, there are many available, which can lead to confusion and poor inhaler technique. It is important for a patient to be happy with their inhaler. This study looked at how patients liked the re-usable Respimat® Soft Mist™ inhaler vs. their previous inhaler. It also asked whether they would be willing to continue using the device at the end of the study period.After 4-6 weeks of using the re-usable device, patients reported that they were happy with the inhaler and most would be willing to carry on using it.Overall, these results show that doctors can prescribe Respimat re-usable to patients, even if the patient has not used the inhaler before.

Abstract
Purpose Inhaler therapy is the mainstay of chronic obstructive pulmonary disease (COPD) management. Poor adherence causes disease exacerbation and affects patient mortality. Although the Adherence Starts with Knowledge-20 (ASK-20) questionnaire is a reliable tool for assessing medication adherence, the relationship between the ASK-20 and clinical factors in patients with COPD remains unknown. We investigated the relationship between the ASK-20 and clinical factors, and assessed real-world inhaler therapy use. Patients and Methods A multicenter, cross-sectional study of outpatients with COPD undergoing inhaler treatment who completed the ASK-20 questionnaire was performed. We investigated COPD-related health status using the COPD Assessment Test (CAT), psychological status using the Hospital Anxiety and Depression Scale (HADS-anxiety and HADS-depression), respiratory function, patient satisfaction levels, and real-world inhaler therapy use. Results Of the total 319 patients, 87% were male with a median age of 74 years. Most patients had mild or moderate COPD, according to Global Initiative for Chronic Obstructive Lung Disease stage. The total ASK-20 scores correlated significantly with the CAT, HADS-anxiety, and HADS-depression scores (r = 0.27, 0.33, and 0.29, respectively, p < 0.01). Multivariable analysis showed that CAT and HADS-anxiety scores had an independent and significant impact on the ASK-20 scores [β, standardized regression coefficient: 0.18 (95% CI, 0.03–0.35; p = 0.02), and 0.29 (95% CI, 0.17–0.42; p < 0.01), respectively]; however, the ASK-20 scores were not correlated with age, sex, body mass index, cohabitation, modified Medical Research Council Dyspnea Scale score, pulmonary function, disease duration, number of COPD exacerbations per year, comorbidities, inhaler numbers, nor inhaler components. Conclusion The ASK-20 scores in patients with COPD were significantly associated with CAT and HADS scores. In Japan, Respimat was prescribed to younger patients and patients with lower CAT scores. The ASK-20, a simple evaluation method, is useful for identifying clinical factors affecting adherence in patients with COPD.

Abstract
Introduction Chronic obstructive pulmonary disease (COPD) is a progressive disease requiring maintenance therapy. According to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) strategy report, bronchodilation with long-acting muscarinic antagonists (LAMAs) and long-acting β2-agonists (LABAs), administered via inhalers, is currently the mainstay of COPD treatment. Combined LAMA/LABA therapies have been shown to improve patient health status, lung function and breathlessness. Here, we wanted to report patient satisfaction with the Respimat® Soft Mist™ inhaler (SMI). Methods This was a pooled analysis of SPIRIT® (NCT02675517) and OTIVACTO® (NCT02719639), two open-label, single-arm, non-interventional studies of physical function in patients with COPD. Patients were treated with tiotropium/olodaterol 5/5 μg for approximately 6 weeks via the SMI. SPIRIT was conducted in Germany; OTIVACTO was conducted in nine European countries. The primary endpoints have been reported previously. Here, we assess patient satisfaction with inhalation and handling, and patient adherence to treatment with the tiotropium/olodaterol SMI in patients with COPD. These were assessed through self-reported questionnaires and physician general assessments. Results Baseline data were collected from 9180 patients from the SPIRIT and OTIVACTO studies. The majority of patients were GOLD group A (25.59%) or B (46.12%). After 6 weeks of treatment with tiotropium/olodaterol, 85.78% of patients were ‘satisfied’ or ‘very satisfied’ with inhaling from the device, and 84.33% of patients were ‘satisfied’ or ‘very satisfied’ with the handling of the inhaler. Treating physicians reported patient adherence as ‘high’ during the study, with 98.57% of patients regularly using the tiotropium/olodaterol SMI. Furthermore, 95.45% of patients expressed a willingness to continue using the tiotropium/olodaterol SMI at the end of the observation period. Conclusion In this study, over 9000 patients reported satisfaction with respect to inhalation and handling of the Respimat SMI, and patient adherence was high. Trial registration ClinicalTrials.gov: NCT02675517 (SPIRIT) and NCT02719639 (OTIVACTO). Inhalation devices are the main method of delivering treatments to patients with chronic obstructive pulmonary disease (COPD). However, there are many devices available, which can lead to confusion and poor inhaler technique. To help doctors decide which device to give to their patients, they consider whether the patient would be happy with the device and whether they can use it correctly. This study pooled data from two large real-life studies to assess patient satisfaction with the Respimat® Soft Mist™ inhaler. Patients assessed their satisfaction and willingness to continue using the device at the end of the study period. The pooled data included over 9000 patients on a range of baseline therapies. After 6 weeks of using the trial device, over 85% of patients were satisfied or very satisfied with inhaling from the device, and over 84% were satisfied with the handling of the device. Physicians reported that nearly 99% of patients regularly used their device. Also, over 95% of the patient population reported that they continued using the inhaler at the end of the study. Overall, these results support the view that many patients with COPD across a wide range of severities and baseline characteristics demonstrated satisfaction with the Respimat® Soft Mist™ inhaler to control their disease.

Abstract
BACKGROUND Bronchodilators administered through inhalation devices are the mainstay treatment for patients with obstructive lung diseases. Patients do not view devices as interchangeable. This systematic review and meta-analysis examined device feature preferences among patients with obstructive lung diseases treated with handheld inhalers. STUDY APPRAISAL AND SYNTHESIS METHODS PubMed, EMBASE, PsycINFO, Cochrane, and Google Scholar were searched to identify publications between 2010 and 2019 that met the following criteria:A manual search extended the study period from 2001 to 2019. Random-effects models were used to generate pooled mean effect sizes and 95% confidence intervals (CIs) for preferred device features. Heterogeneity was measured by the I statistic. RESULTS Nineteen studies (n = 11,256) were included in this meta-analysis. Average age ranged from 50.4 to 74.3 years. The majority of patients were male (57%) and had chronic obstructive pulmonary disease (92%).Patients preferred the following device features: CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS:: Adults with obstructive lung diseases preferred small inhaler devices that were portable, durable, perceived as easy to use, and fast in medication administration. Healthcare providers should give due consideration to the patient's device feature preferences when developing a treatment plan that prescribes an inhalation device.

Abstract
Successful treatment for respiratory diseases relies on effective delivery of medication to the lungs using an inhalation device. Different inhalers have distinct characteristics affecting drug administration and patient adherence, which can impact clinical outcomes. We report on the development of the Respimat® soft mist inhaler (SMI) and compare key attributes with metered-dose inhalers (MDIs) and dry powder inhalers (DPIs). The Respimat SMI, a pocket-sized device generating a single-breath, inhalable aerosol, was designed to enhance drug delivery to the lungs, reduce the requirements for patient coordination and inspiratory effort, and improve the patients’ experience and ease of use. The drug deposition profile with Respimat SMI is favorable compared with MDIs and DPIs, with higher drug deposition to the lung and peripheral airways. The slow velocity and long spray duration of the Respimat SMI aerosol also aid patient coordination. Clinical equivalence has been demonstrated for maintenance treatment of chronic obstructive pulmonary disease using once-daily tiotropium between Respimat SMI (5 µg) and HandiHaler DPI (18 µg). In comparative studies, patients preferred Respimat SMI to MDIs and DPIs; they reported that Respimat SMI was easy to use and felt the inhaled dose was delivered. The Respimat SMI, designed to generate a slow-moving and fine mist, is easy to use and effectively delivers drug treatment to the lungs. The patient-centered design of Respimat SMI improved patient satisfaction, and may help to promote long-term adherence and improve clinical outcomes with asthma and chronic obstructive pulmonary disease.

Abstract
PURPOSE Budesonide/formoterol pressurized metered-dose inhaler (pMDI) was removed from a Medicare Part D formulary, and patients switched to fluticasone-based dry powder inhaler (DPI) therapies. This study describes the experience, satisfaction, and disease control among patients with asthma or chronic obstructive pulmonary disease (COPD) who switched due to removal from the formulary. PATIENTS AND METHODS A patient survey was conducted among adults with asthma or COPD who used budesonide/formoterol pMDI for ≥3 months prior to the formulary block and the new medication for ≥3 weeks after switching, recruited by providers in a research panel. Survey comprised both validated instruments (PASAPQ, OEQ, ACQ-6, and CAT) and stand-alone questions. Patient characteristics, switch experience, device and treatment satisfaction, onset of effect, and disease control were compared between disease (asthma and COPD) and medication (once and twice daily) cohorts. Minimal significance for group differences: P≤0.05. RESULTS Among 100 patients, 93% received communication from their doctor or nurse about the switch and 73% received training on using the new inhaler. Patients used their new treatment for an average of 7 months prior to completing the survey. Patient satisfaction with the new therapy was high (PASAPQ; mean overall satisfaction: 6.2 for asthma; 6.0 for COPD; P=0.338). However, asthma was not well controlled (ACQ-6) in 62% of patients with asthma, and 56% of patients with COPD reported high/very high impact of their illness on their lives (CAT). Sixty-eight percent and 70% of patients with asthma and COPD, respectively, required reliever medication (≥3 puffs) most days during the week prior to the survey. There were no significant differences in disease control (ACQ-6, CAT) between once-daily and twice-daily treatments (P>0.05 for both asthma and COPD). CONCLUSION Even when reporting satisfaction with their new medication, objective measures showed substantial morbidity, regardless of DPI device or dosing regimen.

Abstract
INTRODUCTION Chronic obstructive pulmonary disease (COPD) and asthma remain a major health burden. Adherence to inhaled therapy is critical in order to optimize treatment effectiveness. Properly designed questionnaires can assess patients' satisfaction with their inhaler devices. PATIENTS AND METHODS A total of 766 patients with COPD, asthma or Asthma-COPD Overlap (ACO) were initially enrolled. During their first visit, patients were classified into three groups (Diskus™, Elpenhaler®, Turbuhaler®). Patients completed the FSI-10 questionnaire on Day 0 and Day 60. Test-retest reliability was evaluated. RESULTS A total of 705 patients completed the study. FSI-10 questionnaire had good test-retest reliability (Total Intraclass Correlation Coefficient: 0.86). All dry powder inhaler (DPIs) yielded satisfactory results. Median score of FSI-10 questionnaire in first visit (FSI-10-I) was significantly higher for patients receiving Elpenhaler® (45, 95% CI: 44 to 46) than patients receiving Diskus™ (42, 95% CI: 41 to 43) and Turbuhaler® (42, 95% CI: 41 to 43) (p < 0.001). Accordingly, median score of FSI-10 questionnaire in the final visit (FSI-10-II) was significantly higher for patients receiving Elpenhaler® (46, 95% CI: 45 to 47) than patients receiving Diskus™ (42, 95% CI: 41 to 43) and Turbuhaler® (43, 95% CI: 42 to 44) (p < 0.001). CONCLUSION FSI-10 questionnaire had good test-retest reliability and thus can be used in the follow-up of patients with COPD, asthma and ACO. All DPIs were highly acceptable among all study groups. Elpenhaler® achieved significantly higher ratings than Diskus™ and Turbuhaler® in FSI-10 score and presented higher preference among patients with obstructive lung diseases.

Abstract
In recent years, several national chronic obstructive pulmonary disease (COPD) guidelines have been issued. In Serbia, the burden of COPD is high and most of the patients are diagnosed at late stages. Global Initiative for Chronic Obstructive Lung Disease (GOLD) strategy is poorly implemented in real-life practice, as many patients are still prescribed inhaled corticosteroids (ICS)-containing regimens and slow-release theophylline. In this document, we propose an algorithm for treating COPD patients in Serbia based on national experts’ opinion, taking into account global recommendations and recent findings from clinical trials that are tailored according to local needs. We identified four major components of COPD treatment based on country specifics: active case finding and early diagnosis in high-risk population, therapeutic algorithm for initiation and escalation of therapy that is simple and easy to use in real-life practice, de-escalation of ICS in low-risk non-exacerbators, and individual choice of inhaler device based on patients' ability and preferences. With this approach we aim to facilitate implementation of the recommendation, initiate the treatment in early stages, improve cost-effectiveness, reduce possible side effects, and ensure efficient treatment.

Abstract
Tiotropium/olodaterol (Stiolto® Respimat®; Spiolto® Respimat®) is an inhaled fixed-dose combination of the long-acting muscarinic antagonist tiotropium bromide (hereafter referred to as tiotropium) and the long-acting β2-adrenergic agonist olodaterol. It is available in several countries, including the USA, Japan, China and those of the EU, where it is indicated for the long-term maintenance treatment of patients with chronic obstructive pulmonary disease (COPD). The efficacy of tiotropium/olodaterol 5/5 μg/day in patients with COPD was evaluated in phase III or IV trials of 6-52 weeks' duration. Tiotropium/olodaterol improved lung function to a greater extent than each of its individual components or placebo in 12- and 52-week trials. In 6-week trials, tiotropium/olodaterol provided greater lung function benefits over 24 h than the individual components, placebo or twice-daily fluticasone propionate/salmeterol. Tiotropium/olodaterol also demonstrated beneficial effects on health-related quality of life (HR-QoL), dyspnoea, inspiratory capacity, exercise endurance and the need for rescue medication. In an 8-week open-label trial, umeclidinium/vilanterol was superior to tiotropium/olodaterol for the primary endpoint of trough forced expiratory volume in 1 s. The tolerability profile of tiotropium/olodaterol was generally similar to that of the individual components. In conclusion, tiotropium/olodaterol provides a useful option for the maintenance treatment of COPD, with the convenience of once-daily administration via a single inhaler.

Abstract
Inhaled fixed-dose combinations (FDCs) of a long-acting β-agonist (LABA) and a long-acting muscarinic antagonist (LAMA) have become the cornerstone for the maintenance treatment of symptomatic COPD patients. In this regard, global COPD treatment guidelines have recognized the importance of inhaler devices as integral contributors to the effectiveness of LABA/LAMA FDCs and recommend regular assessment of inhaler device use by the patients in order to improve long-term clinical outcomes. Optimal disease control is also highly dependent upon patient preferences and adherence to inhaler devices. This review objectively examines and compares the major inhaler devices used to deliver different LABA/LAMA FDCs, discusses the inhaler device characteristics that determine drug deposition in the airways, real-life preference for inhaler devices, and handling of inhaler devices that impact the results of the long-term management of COPD. The introduction of new LABA/LAMA FDCs, new inhaler devices, and more clinical studies have created confusion among physicians in choosing the optimal inhaled therapy for COPD patients; in this context, this review attempts to provide an evidence-based framework for informed decision-making with a particular focus on the inhaler devices.Funding.

Abstract
OBJECTIVES Understanding inhaler preferences may contribute to improving adherence in COPD patients and improving long-term outcomes. This study aims to identify and quantify preferences for convenience-related inhaler attributes in French moderate-to-severe COPD patients, with discrete choice experiment (DCE) methodology. METHODS Attributes were defined from a literature search, clinician and patient interviews: shape, dose insertion, dose preparation, dose release, dose confirmation, dose counter and reusability. An online DCE was conducted in respondents with self-reported COPD stage 2-4 recruited through a panel. The study questionnaire included twelve choice scenarios per respondent and questions on patient characteristics, treatment and disease severity. Statistical analyses used a mixed logit regression model with random effects. Utility scores were estimated for four types of inhalers: Inhaler A - soft mist inhaler; Inhaler B - reusable soft mist inhaler; Inhaler C - multi-dose dry powder inhaler; and Inhaler D - single dose dry powder inhaler. RESULTS The study was completed by 153 patients (50 females); respondents were 50.4 years old on average; 13 different inhaler devices were reported. The most preferred inhaler is L-shaped, has dose preparation with capsule insertion and a dose counter, and is reusable. Inhaler profiles A and B had the highest utilities (mean of 1.2533 and 0.9578 respectively) compared to inhaler C (0.6315) and D (0.2200). CONCLUSIONS This study showed statistically significant results that the strongest drivers of preference in French users of inhalation devices for COPD are shape, dose counter and reusability. Convenience-related characteristics are important to patients and should be taken into account by clinicians prescribing these devices.

Abstract
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.

Evaluation of the preference, satisfaction and correct use of Breezhaler ® and Respimat ® inhalers in patients with chronic obstructive pulmonary disease - INHALATOR study. Respir Med 2018; 144:61-67. [PMID: 30366585 DOI: 10.1016/j.rmed.2018.10.006] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/04/2018] [Revised: 10/02/2018] [Accepted: 10/06/2018] [Indexed: 11/24/2022]
Abstract
The INHALATOR study was a randomized, multicentre, open label, two-period of 7 days each, crossover study, with 7 days of washout in-between, aiming to evaluate the correct use, satisfaction and preference between Breezhaler® and Respimat® devices in patients under daily use of open Spiriva® or open Onbrize®, as monotherapy for treatment of mild or moderate COPD. Patients aged ≥40 years with a smoking history of at least 10 pack-year were included in the study. Primary endpoint was the rate of correct use of each device at the first day of treatment after reading the drug leaflet information and was evaluated under the supervision of a trained evaluator. At the end of each treatment phase, the inhaler use was re-evaluated and a satisfaction questionnaire was completed. The patients' preference for the inhaler devices was assessed at the end of the study. After exclusions due to screening failures, 140 patients were randomized: 136 received at least one dose of Breezhaler® and 135 of Respimat®. At treatment start, the rate of correct inhaler use was 40.4% (95%CI: 32.2%-48.7%) for Breezhaler® and 36.3% (95%CI: 28.2%-44.4%) for Respimat® (p = 0.451). After 7 days, the rates were 68.9% (95%CI: 61.1%-76.7%) and 60.4% (95%CI: 52.2%-68.7%), respectively (p = 0.077). According to the Feeling of Satisfaction with Inhaler Questionnaire - FSI 10 patients were more satisfied using Breezhaler® than Respimat® and 57.1% preferred using Breezhaler® (p = 0.001) while 30.1% preferred Respimat® (p < 0.001).

Abstract
Asthma and chronic obstructive pulmonary disease (COPD) can be debilitating conditions adversely affecting a person's quality of life. Effective treatments are available, but common errors in the use of inhalers compound the issue of disease control. The beliefs and concerns of a patient can also have an impact on treatment adherence, the consequences of which are diminished disease control and the occurrence of exacerbations. Once a treatment has been prescribed, it is often nurses who manage the patient long-term, and they may even be the main care provider. This puts nurses in a key position to monitor inhaler technique, communicate with the patient to improve adherence, and even suggest alternative treatments if the patient and therapy are incompatible. This review examines the central role that nurses play in disease management and emphasizes how effective inhaler education can make a difference to disease control. Good communication between the nurse and patient is vital if this is to be achieved. Recent updates to asthma and COPD guidelines are reviewed, and key resources available to help manage patients are highlighted. Finally, with regard to inhaler education, we reconsider the nursing keystones of "Know it," "Show it," "Teach it," and "Review it."

Abstract
When it comes to the use in inhalers in the management of chronic obstructive pulmonary diseases, there are many options, considerations and challenges, which health care professionals need to address. Considerations for prescribing and dispensing, administering and following up, education, and adherence; all of these factors impact on treatment success and all are intrinsically linked to the device selected. This review brings together relevant evidence, real-life data and practice tools to assist health care professionals in making decisions about the use of inhalers in the management of chronic obstructive pulmonary diseases. It covers some of the key technical device issues to be considered, the evidence behind the role of inhalers in disease control, population studies which link behaviors and adherence to inhaler devices as well as practice advice on inhaler technique education and the advantages and disadvantages in selecting different inhaler devices. Finally, a list of key considerations to aid health care providers in successfully managing the use of inhaler devices are summarized.

Abstract
Background Nonadherence to medication and incorrect use of inhalers represent significant barriers to optimal disease management of patients with chronic obstructive pulmonary disease (COPD). Thus, health care professionals (HCPs) play a critical role in educating their patients on appropriate inhaler use and in ensuring medication adherence. However, many patients do not receive appropriate inhaler training or have not had their inhaler technique checked. Methods The Real-life Experience and Accuracy of inhaLer use (REAL) survey was a computer-assisted, telephonic survey consisting of 23 questions gathering real-world information on correct inhaler use, inhalation technique, device attributes, adherence, dosing accuracy, training, correct device use, ease of use, and factors that influence patient adherence in commercially available inhalers delivering COPD maintenance therapy. All results are based on patient-reported data. Results The survey was conducted between January 4, 2016 and February 2, 2016. A total of 764 patients using various inhalers (Breezhaler® =186; Ellipta® =191; Genuair® =194; Respimat® =201) with mild to very severe COPD, with a mean ± SD age 56±9.8 years, completed the survey. Patient self-reported adherence was significantly lower in younger patients compared to older patients (p=0.020). Eighty-three percent of patients indicated that a demonstration (in-person) was "very helpful" versus 58% for video. Patient preferences for training methods were as follows: demonstration of inhaler use (83%), video (58%), instructions for use (51%), and leaflet (34%). Twenty-nine percent of patients had not been checked to see if they were using their device correctly by a HCP within the last two years. Patients who were checked were significantly more adherent than unchecked patients (p=0.020). The majority of the patients using Breezhaler reported either being very confident or confident of having taken a full dose, which was higher than those using Genuair, Ellipta (α=0.05), and Respimat (α=0.05). Treatment adherence in the last 30 days was highest with Breezhaler followed by Respimat, Ellipta, and Genuair. Conclusion The REAL survey identified attributes that influenced patient adherence and optimal inhaler use. Predictive attributes that influence patient adherence which HCPs should be aware of include age and disease severity. Modifiable attributes which the HCP can influence include correct inhaler use training, choice of training methods, checking patient inhaler technique at subsequent visits, and device selection. Inhalers are integral in the effective management of patients with COPD; it is therefore important that patients use the inhaler correctly and have full confidence in the dosage.

Abstract
PURPOSE Chronic obstructive pulmonary disease (COPD) and asthma are leading causes of morbidity and mortality. This narrative review provides an appraisal of the pharmacological and clinical characteristics of tiotropium in COPD and asthma, and examines how these compare with other long-acting bronchodilators. The evidence base is placed into context by relating it to factors affecting clinicians' choice of therapy. MAIN FINDINGS Desirable attributes of a long-acting muscarinic antagonist (LAMA) maintenance therapy include effective pharmacological bronchodilation, improved lung function, exacerbation efficacy, and positive effects on symptom control, exercise capacity and quality of life across a broad patient population. Tolerability and convenience of use are also important for patient well-being and treatment adherence. Tiotropium shows higher affinity for muscarinic receptors than ipratropium, and prolonged binding to the M3 receptor compared with other LAMAs. In COPD, tiotropium has demonstrated improved lung function and exacerbation prevention compared with placebo or long-acting β2-agonists, similar exacerbation efficacy to other LAMAs, and enhanced symptom control and health status versus placebo. UniTinA-asthma® showed the benefits of add-on tiotropium in patients with uncontrolled mild to moderate and severe asthma. Tiotropium is well tolerated, with an incidence of adverse events similar to placebo, except for known infrequent side effects of anticholinergics. Tiotropium HandiHaler® and Respimat® augment inhaler choice in COPD. PRINCIPAL CONCLUSIONS With over 10 years' prescribing history and 50 million patient-years of use, tiotropium has the benefit of a more extensive clinical evidence base than other long-acting bronchodilators, with demonstrated efficacy and safety in COPD and symptomatic asthma.

Abstract
BACKGROUND Inhaled medication is the cornerstone of the pharmacological treatment for patients with asthma and chronic obstructive pulmonary disease (COPD). Several inhaler devices exist, and each device has specific characteristics to achieve the optimal inhalation of drugs. The correct use of inhaler devices is not granted and patients may incur in mistakes when using pressurized metered-dose inhalers (pMDIs) or dry-powder inhaler (DPIs). The incorrect use of inhaler devices can lead to a poorly controlled disease status. Unfortunately, guidelines provide limited guidance regarding the choice of devices. This article presents a review of the literature on different inhaler device requirements. Data from literature (PubMed and Google Scholar) on the commercially available inhaler devices have been evaluated and the history of inhaler medicine described. Furthermore, advantages and disadvantages of each type of device have been analyzed. The evaluation of literature indicated the availability of robust data on the devices characteristics and factors influencing selection of delivery devices. Each type of device has its own pro and cons. The age, cognitive status, visual acuity, manual dexterity, manual strength and ability to coordinate the inhaler actuation with inhalation may be as important as the disease severity in determining the correct approach to delivery of respiratory medication. The administration of effective therapies via a device that is simple to use and accepted by patients may help to improve treatment outcomes in patients with COPD.

Abstract
Background Poor adherence to inhaled therapy is common in patients with asthma and COPD. An inhaler selection based on patients’ preference could be beneficial to adherence and treatment effectiveness. Properly designed questionnaires can assess patients’ satisfaction with their medication devices. The aim of this study was to estimate, using the Feeling of Satisfaction with Inhaler (FSI-10) questionnaire, the ease of use and satisfaction of patients regarding three different marketed dry powder inhalers (DPIs): Diskus® (DK), Elpenhaler® (EH), and Turbuhaler® (TH). The FSI-10 is a self-completed questionnaire to assess patients’ opinions regarding ease of use, portability, and usability of devices, irrespective of the drug used. Patients and methods We performed a 4-week, open, noninterventional, multicenter, parallel clinical study in 560 asthmatic and 561 COPD patients. During the first visit, patients were classified into three groups according to the DPI they were already using. Patients were regularly receiving their treatments (Seretide DK, Rolenium EH, and Symbicort TH) and agreed to complete the FSI-10 questionnaire in the second visit. Results A total of 517 COPD and 523 asthma patients completed the study. All DPIs tested received satisfactory results, while the EH obtained consistently higher scores in the FSI-10 in both COPD and asthma patients (44.7 and 44.1 vs 41.5 and 43 for TH, 40.8 and 41.4 for DK, P<0.001 and P<0.01, respectively). TH was rated better than DK by asthma patients. Patients suffering with severe COPD tended to express higher feeling of satisfaction than those with moderate or mild disease, irrespective of the device used. Conclusion All DPIs tested were highly acceptable by asthma and COPD patients of different ages; nevertheless, EH received significantly higher ratings in most of the questionnaire domains. COPD patients in advanced stages of the disease generally expressed higher level of satisfaction with their devices.
