Abstract
INTRODUCTION In the management of chronic obstructive pulmonary disease (COPD), inhalation therapy plays a pivotal role. However, clinicians often face the dilemma of choosing between single and multiple inhaler therapies for their patients. This choice is critical because it can affect treatment efficacy, patient adherence, and overall disease management. AREAS COVERED This article examines the advantages and factors to be taken into consideration when selecting between single and multiple inhaler therapies for COPD. EXPERT OPINION Both single and multiple inhaler therapies must be considered in COPD management. While single inhaler therapy offers simplicity and convenience, multiple inhaler therapy provides greater flexibility and customization. Clinicians must carefully evaluate individual patient needs and preferences to determine the most appropriate inhaler therapy regimen. Through personalized treatment approaches and shared decision-making, clinicians can optimize COPD management and improve patient well-being. Nevertheless, further research is required to compare the effectiveness of single versus multiple inhaler strategies through rigorous clinical trials, free from industry bias, to determine the optimal inhaler strategy. Smart inhaler technology appears to have the potential to enhance adherence and personalized management, but the relative merits of smart inhalers in single inhaler regimens versus multiple inhaler regimens remain to be determined.

Preparation and Evaluation of Inhalable Microparticles with Improved Aerodynamic Performance and Dispersibility Using L-Leucine and Hot-Melt Extrusion. Pharmaceutics 2024; 16:784. [PMID: 38931905 PMCID: PMC11206964 DOI: 10.3390/pharmaceutics16060784] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2024] [Revised: 06/03/2024] [Accepted: 06/04/2024] [Indexed: 06/28/2024] Open
Abstract
Dry-powder inhalers (DPIs) are valued for their stability but formulating them is challenging due to powder aggregation and limited flowability, which affects drug delivery and uniformity. In this study, the incorporation of L-leucine (LEU) into hot-melt extrusion (HME) was proposed to enhance dispersibility while simultaneously maintaining the high aerodynamic performance of inhalable microparticles. This study explored using LEU in HME to improve dispersibility and maintain the high aerodynamic performance of inhalable microparticles. Formulations with crystalline itraconazole (ITZ) and LEU were made via co-jet milling and HME followed by jet milling. The LEU ratio varied, comparing solubility, homogenization, and aerodynamic performance enhancements. In HME, ITZ solubility increased, and crystallinity decreased. Higher LEU ratios in HME formulations reduced the contact angle, enhancing mass median aerodynamic diameter (MMAD) size and aerodynamic performance synergistically. Achieving a maximum extra fine particle fraction of 33.68 ± 1.31% enabled stable deep lung delivery. This study shows that HME combined with LEU effectively produces inhalable particles, which is promising for improved drug dispersion and delivery.

A comprehensive evaluation of online inhaler use techniques for obstructive airway disease. Respir Med 2024; 226:107607. [PMID: 38548142 DOI: 10.1016/j.rmed.2024.107607] [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: 01/10/2024] [Revised: 03/02/2024] [Accepted: 03/18/2024] [Indexed: 04/06/2024]
Abstract
BACKGROUND Pulmonary inhaler therapy is a core treatment modality for >600 million individuals affected by obstructive airways disease globally. Poor inhaler technique is associated with reduced disease control and increased health care utilization; however, many patients rely on the internet as a technical resource. This study assesses the content and quality of online resources describing inhaler techniques. METHODS A Google search was conducted in April 2023 capturing the top 5 search results for 12 common inhaler devices. Websites were compared to product monographs for preparation/first use, inhalational technique, and post-usage/device care. They were also assessed using accepted quality metrics (GQS, DISCERN, JAMA Benchmark scores) and clinically relevant aspects based on the literature and consensus statements. RESULTS Websites regularly excluded critical steps important for proper inhaler technique. They performed best on information related directly to inhalation technique (average median score 78%), whereas steps related to preparation/first use (58%) or post-usage/device care (50%) were less frequently addressed. Median GQS, DISCERN, and JAMA Benchmark scores were 3 [IQR 3-4], 3 [IQR 2-4], and 1 [IQR 1-3], respectively. Clinically relevant factors were only addressed in about one-fifth of websites with no websites addressing smoking cessation, environmental considerations, or risk factors for poor technique. CONCLUSIONS This study highlights gaps in online resources describing inhaler technique, particularly related to preparation/first use and post-usage/device care steps. Clinically relevant factors were rarely addressed across websites. Improvements in these areas could lead to enhanced inhaler technique and clinical outcomes.

BMC Pulm Med 2023; 23:358. [PMID: 37740178 PMCID: PMC10517547 DOI: 10.1186/s12890-023-02651-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Accepted: 09/11/2023] [Indexed: 09/24/2023] Open
Abstract
BACKGROUND Transition from hospital to home is a vulnerable period for patients with COPD exacerbations, with a high risk for readmission and mortality. Twenty percent of patients with an initial hospitalization for a COPD exacerbation are readmitted to a hospital within 30 days, costing the health care system over $15 billion annually. While nebulizer therapy directed at some high-risk COPD patients may improve the transition from hospital to home, patient and social factors are likely to contribute to difficulties with their use. Current literature describing the COPD patient's experience with utilizing nebulizer therapy, particularly during care transitions, is limited. Therefore, the objective of this study was to explore underlying COPD patient and social factors contributing to practical difficulties with nebulizer use at the care transition from hospital to home. METHODS This was a qualitative study conducted between September 2020 and June 2022. Patients were included if they were ≥ 40 years old, had a current diagnosis of COPD, had an inpatient admission at a hospital, and were discharged directly to home with nebulizer therapy. Semi-structured, one-on-one interviews with patients were conducted covering a broad range of patient and social factors and their relationships with nebulizer use and readmission. Interviews were recorded and transcribed verbatim. A thematic analysis was performed using a mixed inductive and deductive approach. RESULTS Twenty-one interviews were conducted, and subjects had a mean age of 64 ± 8.4 years, 62% were female, and 76% were White. The predominant interview themes were health care system interactions and medication management. The interviews highlighted that discharge counseling methods and depth of counseling from hospitals were inconsistent and were not always patient-friendly. They also suggested that patients could appropriately identify, set up, and utilize their nebulizer treatment without difficulties, but additional patient education is required for nebulizer clean up and maintenance. CONCLUSIONS Our interviews suggest that there is room for improvement within the health care system for providing consistent, effective discharge counseling. Also, COPD patients discharged from a hospital on nebulizer therapy can access and understand their treatment but require additional education for nebulizer clean up and maintenance.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) mainly affects individuals aged 60 and older. The proper use of inhalers is crucial for managing COPD. This study aimed to evaluate the prevalence and factors affecting the appropriate use of inhalers among elderly patients with COPD. METHODS We enrolled 91 elderly patients with COPD admitted to the Department of Respiratory, University Medical Center HCMC between October 2020 and May 2021. Patients who were capable of using the inhaler would have their inhaler usage recorded through video footage. Two respiratory experts carefully analyzed 133 video-recorded demonstrations for evaluation purposes. RESULTS 18.7% of the patients demonstrated the correct inhaler technique. Pressurized metered dose inhaler (pMDI) and Turbuhaler had the lowest documented correct usage rates (11.9% and 10.0%, respectively). Two critical steps, namely "holding breath for about five seconds or as long as comfortable" and "breathing out gently," were commonly performed incorrectly when using pMDI, Respimat, Breezhaler, or Turbuhaler. Multivariable logistic regression analysis showed that lower mMRC scores (AOR = 5.3, CI 1.1-25.5, p = 0.037) and receiving inhaler instruction within the past three months (AOR = 5.2, CI 1.3-20.1, p = 0.017) were associated with increased odds of using the inhaler correctly. CONCLUSIONS Our study found that less than 20% of elderly patients with COPD use inhalers correctly. Common errors include inadequate breath-holding and gentle exhalation. mMRC scores and recent inhaler instruction were predictors of proper use. These findings can aid clinicians in improving inhaler management for elderly patients with COPD.

Abstract
Older adults have a higher prevalence of chronic obstructive pulmonary disease (COPD), which will likely increase substantially in the coming decades owing to aging populations and increased long-term exposure to risk factors for this disease. COPD in older adults is characterized by low-grade chronic systemic inflammation, known as inflamm-aging. It contributes substantially to age-associated pulmonary changes that are clinically expressed by reduced lung function, poor health status, and limitations in activities of daily living. In addition, inflamm-aging has been associated with the onset of many comorbidities commonly encountered in COPD. Furthermore, physiologic changes that are often seen with aging can influence the optimal treatment of older patients with COPD. Therefore, variables such as pharmacokinetics, pharmacodynamics, polypharmacy, comorbidities, adverse drug responses, drug interactions, method of administration, and social and economic issues that impact nutrition and adherence to therapy must be carefully evaluated when prescribing medication to these patients because each of them alone or together may affect the outcome of treatment. Current COPD medications focus mainly on alleviating COPD-related symptoms, so alternative treatment approaches that target the disease progression are being investigated. Considering the importance of inflamm-aging, new anti-inflammatory molecules are being evaluated, focusing on inhibiting the recruitment and activation of inflammatory cells, blocking mediators of inflammation thought to be important in the recruitment or activation of these inflammatory cells or released by these cells. Potential therapies that may slow the aging processes by acting on cellular senescence, blocking the processes that cause it (senostatics), eliminating senescent cells (senolytics), or targeting the ongoing oxidative stress seen with aging need to be evaluated.

Abstract
Introduction Inhalation therapy is a cornerstone of treating patients with chronic obstructive pulmonary disease (COPD). Inhaler devices might influence the effectiveness of inhalation therapy. We aimed to model and compare the deposition of acting agents of an open and a fixed dose combination (FDC) triple therapy and examine their repeatability. Methods We recruited control subjects (Controls, n = 17) and patients with stable COPD (S-COPD, n = 13) and those during an acute exacerbation (AE-COPD, n = 12). Standard spirometry was followed by through-device inhalation maneuvers using a pressurized metered dose inhaler (pMDI) and a soft mist inhaler (SMI) to calculate deposition of fixed dose and open triple combination therapies by numerical modeling. Through-device inspiratory vital capacity (IVCd) and peak inspiratory flow (PIFd), as well as inhalation time (tin) and breath hold time (tbh) were used to calculate pulmonary (PD) and extrathoracic deposition (ETD) values. Deposition was calculated from two different inhalation maneuvers. Results There was no difference in forced expiratory volume in 1 s (FEV1) between patients (S-COPD: 42 ± 5% vs. AE-COPD: 35 ± 5% predicted). Spiriva® Respimat® showed significantly higher PD and lower ETD values in all COPD patients and Controls compared with the two pMDIs. For Foster® pMDI and Trimbow® pMDI similar PD were observed in Controls, while ETD between Controls and AE-COPD patients did significantly differ. There was no difference between COPD groups regarding the repeatability of calculated deposition values. Ranking the different inhalers by differences between the two deposition values calculated from separate maneuvers, Respimat® produced the smallest inter-measurement differences for PD. Discussion Our study is the first to model and compare PD using pMDIs and an SMI as triple combination in COPD. In conclusion, switching from FDC to open triple therapy in cases when adherence to devices is maintanined may contribute to better therapeutic effectiveness in individual cases using low resistance inhalers.

Abstract
BACKGROUND Maintaining correct inhaler technique is crucial in the management of chronic obstructive pulmonary disease (COPD). We aimed to investigate the inhaler technique in patients with COPD, to compare it immediately after and at 1 month after training, and to identify the predictors of incorrect inhaler use at 1 month after training. METHODS This prospective study was conducted at the COPD clinic of Siriraj Hospital (Bangkok, Thailand). Patients demonstrating improper inhaler use were trained face-to-face by pharmacists. Inhaler technique was re-assessed immediately after and at 1 month after training. The Montreal Cognitive Assessment (MoCA) score, pulmonary function tests, 6-min walk distance (6 MWD), modified Medical Research Council scale score, and COPD Assessment Test (CAT) score were evaluated. RESULTS Sixty-six patients with COPD who demonstrated at least one critical error during the use of any controller inhaler were enrolled. The mean age was 73.0 ± 9.0 years, and 75.8% patients had moderate/severe COPD. Immediately after training, all patients used dry powder inhalers correctly and 88.1% used pressurized metered-dose inhalers correctly. At 1 month, the number of patients demonstrating the correct technique decreased across all devices. Multivariable analysis revealed that MoCA score ≤ 16 was independently associated with a critical error at 1 month after training (adjusted odds ratio: 12.7, 95% confidence interval: 1.8-88.2, p = 0.010). At 1 month, CAT score (11.4 ± 8.9 vs. 8.4 ± 5.5, p = 0.018) and 6 MWD (351 ± 93 m vs. 372 ± 92 m, p = 0.009) had significantly improved in patients demonstrating the correct technique, and CAT score met the minimal clinically important difference. CONCLUSIONS Face-to-face training by pharmacists improved patient performance. However, the number of patients following proper technique had decreased at 1 month after training. Cognitive impairment (MoCA score ≤ 16) independently predicted the ability of COPD patients to maintain proper inhaler technique. Assessment of cognitive function combined with technical re-assessment and repeated training should improve COPD management.

Abstract
A Dry Powder Inhaler (DPI) is a technique as well as a device used to inhale formulation which is in the form of dry powder, and is inhaled through the nose or mouth. It was developed for the purpose of treating conditions like chronic obstructive pulmonary disease (COPD), Asthma, and even cystic fibrosis etc. The aim of the review is to discuss the different methods of preparation of dry powders along with the characterization of DPI. Here we present the outline of different methods like supercritical fluid extraction (SCF), spray drying, and milling. The review focussed on various devices including single and multi-dose devices used in the DPI. It also highlights on recent advances in the DPI including nano particulate system, siRNA-based medication, liposomes, and pro-liposomes based delivery. In COVID-19 silver nanoparticles-based DPIs provide very prominent results in the infected lungs. Moreover, this review states that the AI-based DPI development provides and improvement in the bioavailability and effectiveness of the drug along with the role of artificial neural networks (ANN). The study also showed that nasally administered drugs (nose to brain) can easily cross the blood-brain barrier (BBB) and enter the central nervous system (CNS) through the olfactory and trigeminal pathway which provides effective CNS concentrations at lower dosage. It is suggested that DPIs not only target respiratory complications but also treat CNS complications too. This review provides support and guides the researcher in the recent development and evaluation of DPI.

Abstract
Accurate evaluation of inhaler handling is essential for improved treatment of bronchial asthma (BA) and chronic obstructive pulmonary disease (COPD). Many studies have described the correlation between age, inhalation guidance, and procedure improvement. Elderly patients should receive proper inhalation guidance. This was a retrospective open cohort study conducted at a single hospital with outpatient open pharmacies that provided inhalation guidance to patients of BA and COPD. A total of 525 cases were included in the study. The median age was 71 years with no significant difference between genders (males: 71 ± 16.0 years; females: 72 ± 16.1 years; P = .24). There were 226 males (43.0%) and 299 females (57.0%; P = .03). BA was significantly more prevalent than COPD (P < .001). There was no significant difference in dry powder inhaler (DPI) and pressurized metered-dose inhaler (pMDI) visits in those <60 years of age (P = .23). pMDI was used significantly more often than DPI in those aged 60 to 90 years of age (P < .001). In both <70 and >70 years of age, the most common error with DPI use was improper inhalation speed, which reduced (improved) at the third visit. Gargling errors were most common with DPI use at the second visit and with pMDI at the first visit in both age groups, which subsequently reduced rapidly. Continuous repeated guidance steadily and significantly decreased errors with all devices (P < .001 for DPI, pMDI, and soft mist inhaler). Elderly cases (>70 years of age) should undergo continuous repeated guidance to reduce inhalation errors like inhalation speed and gargling errors.

Abstract
Inhalational therapy, today, happens to be the mainstay of treatment in obstructive airway diseases (OADs), such as asthma, chronic obstructive pulmonary disease (COPD), and is also in the present, used in a variety of other pulmonary and even non-pulmonary disorders. Hand-held inhalation devices may often be difficult to use, particularly for children, elderly, debilitated or distressed patients. Nebulization therapy emerges as a good option in these cases besides being useful in the home care, emergency room and critical care settings. With so many advancements taking place in nebulizer technology; availability of a plethora of drug formulations for its use, and the widening scope of this therapy; medical practitioners, respiratory therapists, and other health care personnel face the challenge of choosing appropriate inhalation devices and drug formulations, besides their rational application and use in different clinical situations. Adequate maintenance of nebulizer equipment including their disinfection and storage are the other relevant issues requiring guidance. Injudicious and improper use of nebulizers and their poor maintenance can sometimes lead to serious health hazards, nosocomial infections, transmission of infection, and other adverse outcomes. Thus, it is imperative to have a proper national guideline on nebulization practices to bridge the knowledge gaps amongst various health care personnel involved in this practice. It will also serve as an educational and scientific resource for healthcare professionals, as well as promote future research by identifying neglected and ignored areas in this field. Such comprehensive guidelines on this subject have not been available in the country and the only available proper international guidelines were released in 1997 which have not been updated for a noticeably long period of over two decades, though many changes and advancements have taken place in this technology in the recent past. Much of nebulization practices in the present may not be evidence-based and even some of these, the way they are currently used, may be ineffective or even harmful. Recognizing the knowledge deficit and paucity of guidelines on the usage of nebulizers in various settings such as inpatient, out-patient, emergency room, critical care, and domiciliary use in India in a wide variety of indications to standardize nebulization practices and to address many other related issues; National College of Chest Physicians (India), commissioned a National task force consisting of eminent experts in the field of Pulmonary Medicine from different backgrounds and different parts of the country to review the available evidence from the medical literature on the scientific principles and clinical practices of nebulization therapy and to formulate evidence-based guidelines on it. The guideline is based on all possible literature that could be explored with the best available evidence and incorporating expert opinions. To support the guideline with high-quality evidence, a systematic search of the electronic databases was performed to identify the relevant studies, position papers, consensus reports, and recommendations published. Rating of the level of the quality of evidence and the strength of recommendation was done using the GRADE system. Six topics were identified, each given to one group of experts comprising of advisors, chairpersons, convenor and members, and such six groups (A-F) were formed and the consensus recommendations of each group was included as a section in the guidelines (Sections I to VI). The topics included were: A. Introduction, basic principles and technical aspects of nebulization, types of equipment, their choice, use, and maintenance B. Nebulization therapy in obstructive airway diseases C. Nebulization therapy in the intensive care unit D. Use of various drugs (other than bronchodilators and inhaled corticosteroids) by nebulized route and miscellaneous uses of nebulization therapy E. Domiciliary/Home/Maintenance nebulization therapy; public & health care workers education, and F. Nebulization therapy in COVID-19 pandemic and in patients of other contagious viral respiratory infections (included later considering the crisis created due to COVID-19 pandemic). Various issues in different sections have been discussed in the form of questions, followed by point-wise evidence statements based on the existing knowledge, and recommendations have been formulated.

Abstract
OBJECTIVE To investigate the effect of pharmacist-led inhaler technique assessment service on readmissions and CAT-score in hospitalized COPD patients. Furthermore, to provide an effect estimate for sample size calculations for future studies and to gain experience on the feasibility of such studies. METHODS A randomized controlled pilot study. Patients were randomized 1:1 to intervention or standard care. The primary endpoint was the difference in time to first readmission after hospital discharge between the treatment groups. RESULTS There was no statistically significant effect on the time to readmission (median 41 days in the intervention group (19 patients) and 95 days in the control group (20 patients), HR 1.74, 95% CI 0.81-3.75, p = 0.16). There was no statistically significant difference between the groups in CAT-score 2 months after discharge, median scores being 25.5 and 24 in the intervention and the control group, respectively (p = 0.29). There was, however, a reduction of 3.5 units in CAT-score from baseline to 2 months after discharge in the intervention group, compared to no change in the control group. CONCLUSION Pharmacist-led inhaler technique training had no effect on time to readmission or CAT-score. Future studies in larger populations should consider focusing on patients with less severe COPD, exploring CAT-score as a primary endpoint, consider stratifying for important baseline variables and evaluate the acceptability of the intervention.

Abstract
There are many different inhaler devices and medications on the market for the treatment of asthma and chronic obstructive pulmonary disease, with over 230 drug-delivery system combinations available. However, despite the abundance of effective treatment options, the achieved disease control in clinical practice often remains unsatisfactory. In this context, a key determining factor is the match or mismatch of an inhalation device with the characteristics or needs of an individual patient. Indeed, to date, no ideal device exists that fits all patients, and a personalized approach needs to be considered. Several useful choice-guiding algorithms have been developed in the recent years to improve inhaler–patient matching, but a comprehensive tool that translates the multifactorial complexity of inhalation therapy into a user-friendly algorithm is still lacking. To address this, a multidisciplinary expert panel has developed an evidence-based practical treatment tool that allows a straightforward way of choosing the right inhaler for each patient.

A Bayesian Framework to Assess the Usability of Dry Powder Inhalers in a Cohort of Asthma Adolescents in Italy. CHILDREN 2021; 9:children9010028.

Abstract
The useability of DPIs (dry powder inhalers) depends on several factors that are influenced by the patients’ subjectivity and objectivity. The short-form global usability score (S-GUS), a specific tool for the quick ranking and comparison in real life of an inhaler’s usability, was used to investigate six of the most prescribed DPIs (Breezhaler, Diskus, Ellipta, Nexthaler, Spiromax, and Turbohaler) in consecutive asthma patients aged <18 years. A Bayesian indirect comparison (IC) was carried out to merge all pairwise comparisons between the six DPIs. Thirty-three subjects participated: eighteen tested Breezhaler, Spiromax, Nexthaler, and Ellipta simultaneously, while fifteen tested Breezhaler, Spiromax, Diskus, and Turbohaler. The estimates of the S-GUS, by the IC model, allowed us to rank the DPIs by their degree of usability: Ellipta, Diskus, and Spiromax were classified as “good to pretty good” (S-GUS > 15), while Spiromax, Turbohaler, and Breezhaler were classified as “insufficient” (S-GUS < 15). The multidomain assessment is recommended in asthma adolescents in order to approximate the effective usability of different DPIs as best as possible. The S-GUS proves particularly suitable in current clinical practice because of the short time required for its use in adolescents.

Abstract
Many inhaler devices with varying handling requirements for optimal use are available for the treatment of asthma and chronic obstructive pulmonary disease (COPD). Patients may be prescribed different device types for reliever and maintenance medications, which may lead to confusion and suboptimal device use. We aimed to understand whether simplifying inhaler regimens by employing a single device type in patients who use multiple devices or prescribing a device with which a patient was already experienced could improve clinical and economic outcomes in asthma and COPD management. A targeted literature search was performed and additional articles were identified through hand searching citations within screened publications. A total of 114 articles were included in the final review. Findings suggest that simplifying inhaler regimens by applying the same type of inhaler for concomitant inhaled medications over time minimizes device misuse, leading to improved clinical outcomes and reduced health care use in patients with asthma or COPD. Physicians should consider a patient's suitability for a device and training needs when prescribing an inhaled medication and before changing the medication type or dose, especially when suboptimal treatment outcomes are observed. Further research is required to determine whether consistent use of the same device type is associated with better treatment adherence and persistence in patients with asthma or COPD. Nevertheless, this literature review identified clinical benefits and reduced health care use with simplified inhaler regimens.

Abstract
OBJECTIVE AND DESIGN To describe clinical characteristics, medication use, and low peak inspiratory flow rate (PIFR) (< 60 L/min) prevalence in nursing facility residents with chronic obstructive pulmonary disease (COPD). PATIENTS AND SETTING Residents 60 years of age and older with a COPD diagnosis and≥ 6 months' nursing facility residence, were enrolled between December 2017 and February 2019 from 26 geographically varied United States nursing facilities. OUTCOME MEASURES Data, extracted from residents' charts, included demographic/clinical characteristics, COPD-related medications, exacerbations and hospitalizations within the past 6 months, and functional status from the most recent Minimum Data Set. At enrollment, residents completed the modified Medical Research Council (mMRC) Dyspnea Scale and COPD Assessment Test (CAT™). Spirometry and PIFR were also assessed. RESULTS Residents' (N = 179) mean age was 78.0 ± 10.6 years, 63.7% were female, and 57.0% had low PIFR. Most prevalent comorbidities were hypertension (79.9%), depression (49.2%), and heart failure (41.9%). The average forced expiratory volume in 1 second (FEV11) % predicted was 45.9% ± 20.9%. On the CAT, 78.2% scored≥ 10 and on the mMRC Dyspnea Scale, 74.1% scored≥ 2, indicating most residents had high COPD symptom burden. Only 49.2% were receiving a scheduled long-acting bronchodilator (LABD). Among those with low PIFR prescribed a LABD, > 80% used dry powder inhalers for medication delivery. CONCLUSION This study highlights underutilization of scheduled LABD therapy in nursing facility residents with COPD. Low PIFR was prevalent in residents while the majority used suboptimal medication delivery devices. The findings highlight opportunities for improving management and outcomes for nursing facility residents with COPD.

Abstract
Objective: To review the role of pharmacists in educating and monitoring patients with chronic obstructive pulmonary disease (COPD) on inhalation technique. Data Sources: A PubMed search (January 2000 to May 2020) was performed using the following keywords and associated medical subject headings: adherence, chronic obstructive pulmonary disease/COPD, education, inhaler, pharmacist, and technique. Study Selection and Data Extraction: The search was conducted to identify English language articles highlighting the importance of correct inhaler technique in COPD management and benefits of pharmacist inhaler training such as improved adherence, quality of life (QoL), and disease control. Randomized controlled trials, retrospective studies, observational studies, systematic reviews, and meta-analysis reporting pharmacist training were included. Data Synthesis: This review summarizes that incorrect inhaler use negatively affects treatment outcomes, prognosis, and QoL. Pharmacists are in a unique position to educate and monitor patients with COPD on optimal inhaler technique and an individualized, multifactorial approach to COPD management involving pharmacists could provide cost-effective patient care and improve adherence and minimize inhaler misuse. Several strategies used by pharmacists can optimize patient inhaler use, such as face-to-face technique demonstrations, the "teach-back" method, telemonitoring, instructional videos, or informational leaflets. An individualized action plan involving education and regular monitoring of inhaler use further enhances optimal adherence and disease management. Conclusions: As pharmacists are easily accessible to both patients and health care providers, they are ideally placed to play an important role in the enhancement of education on, and continuous assessment of, optimal inhaler technique, thereby improving adherence, disease control, and QoL.

Abstract
Inhalation therapy is the cornerstone of chronic obstructive pulmonary disease (COPD) management. However, for many COPD patients who are managed at home, nebulization therapy offers an effective alternative treatment and fulfills the gap of catering to the specific population of patients who are unable to use handheld inhaler devices appropriately. The present review highlights key aspects, namely selection of the right beneficiaries for home nebulization, available drugs in nebulized formulations for the treatment of COPD, and the importance of care, cleaning, and maintenance, which are prerequisites for ensuring successful nebulization therapy.

Abstract
Patients with stable COPD rely heavily on inhaled bronchodilators and corticosteroids to control symptoms, maximize quality of life, and avoid exacerbations and costly hospitalizations. These drugs are typically delivered by hand-held inhalers or nebulizers. The majority of patients are prescribed inhalers due to their perceived convenience, portability, and lower cost, relative to nebulizers. Unfortunately, poor inhaler technique compromises symptom relief in most of these patients. In contrast to one or two puffs through an inhaler, nebulizers deliver a drug over many breaths, through tidal breathing, and hence are more forgiving to poor inhalation technique. To what extent susceptibility to errors in their use may influence the relative effectiveness of these two types of inhalation device has received little attention in COPD research. In 2005, a systematic review of the literature concluded that nebulizers and inhalers are equally effective in patients who are adequately trained to use their inhalation device. This conclusion was based on two small clinical trials that only examined objective measures of lung function. Since then, additional studies have found that maintenance therapy administered by nebulizers could improve patients' reported feelings of symptom relief, quality of life, and satisfaction with treatment, compared to therapy administered by inhalers. Because it has been 15 years since the publication of the systematic review, in this article we summarize the results of studies that compared the effectiveness of inhalers with that of nebulizers in patients with stable COPD and discuss their implications for clinical practice and need for future research.

Abstract
Background The choice of the Dry Powder Inhaler (DPI) to prescribe is a critical issue. The estimation of DPIs usability depends on the objective assessment of several indices related to both subjective and objective determinants. The Global Usability Score (GUS) Questionnaire is a comprehensive tool usable for checking, comparing, and ranking inhalers' usability objectively in real life, but it takes some time to fill. Aim The aim of this study was to favour the quicker check of DPIs usability in clinical practice by means of a simplified short-form GUS (S-GUS) Questionnaire, while maintaining the high specificity and sensitivity of the original, extended version of the Questionnaire (O-GUS questionnaire). Methods The usability of the six most prescribed DPIs was assessed in 222 patients with persistent airway obstruction and needing long-term inhalation treatments. LASSO regression and multicollinearity test were used to select the subset of questions of the O-GUS questionnaire, with the highest information power. Each item was then scored using the corresponding coefficient in the linear regression (normalized at 50 as the O-GUS score). Agreement between the original and the short-form questionnaire was evaluated using the Cohen's kappa statistic (κ). The overall S-GUS values obtained for each DPI were then compared to those from the O-GUS, in the same patients, using a Bayesian indirect comparison (IC) model. Results After the statistical selection of the items mostly contributing to the overall score, the novel S-GUS questionnaire consists of twelve items only. Nine items are related to patients' opinion before DPIs handling, and three to the nurse's assessment after DPIs practicality. O-GUS and S-GUS score were strongly correlated (R2=0.9843, p<0.0001) and the usability score calculated for each DPI by means of the O- and of S- GUS overlapped almost completely (κ=84.5%, 95% CI 81.3% to 89.2%). Furthermore, S-GUS was much faster to complete than O-GUS (mean time 6.1 vs 23.4 minutes, p<0.001). Estimates of S-GUS, obtained from the IC model, allowed to propose a simple classification of usability: "good" by GUS values >25; "pretty good" by values ≤25≥15, and "insufficient" by values <15. Conclusions The S-GUS proves as much specific and suitable as the extended O-GUS questionnaire in measuring DPIs usability, while maintaining the same high sensitivity. As the time required for its use is quite shorter, S-GUS is also particularly suitable and helpful in current clinical practice.

Abstract
This gamma scintigraphy imaging study assessed pulmonary, extrathoracic and regional lung deposition patterns of a radiolabelled inhaled corticosteroid/long-acting muscarinic antagonist/long-acting β2-agonist triple fixed-dose combination budesonide/glycopyrronium/formoterol fumarate dihydrate (BGF 320/14.4/10 μg), delivered by pressurised metered dose inhaler (pMDI) using innovative co-suspension delivery technology (Aerosphere™). In this Phase I, randomised, single-centre, single-dose, two-period, crossover study (NCT03740373), 10 healthy male adults received two actuations of BGF MDI (160/7.2/4.8 μg per actuation) radiolabelled with 99mTc, not exceeding 5 MBq per actuation. Immediately following each inhalation, subjects performed a 10- or 3-second breath-hold, then exhaled into an exhalation filter. The primary objective was to assess the pulmonary deposition of BGF MDI following the 10-second breath-hold. The secondary objectives were to assess deposition after the 3-second breath-hold and lung regional and extrathoracic deposition after each breath-hold length. Imaging of the lungs, stomach, head and neck was recorded by gamma scintigraphy immediately after exhalation. The mean BGF MDI emitted dose deposited in the lungs was 37.7% for the 10-second breath-hold and 34.5% for the 3-second breath-hold. Emitted dose detected in the exhalation filter was ≤0.4% for both breath-hold lengths. The mean normalised peripheral/central ratio was 0.65 and 0.75 for the 10- and 3-second breath-holds, respectively, while the standardised central/peripheral ratios were 1.79 and 1.40, respectively. There were no new or unexpected safety findings. In conclusion, BGF MDI was efficiently deposited in the central and the peripheral regions of the lungs, with similar regional deposition patterns following a 10- and 3-second breath-hold.

Abstract
Current guidelines recommend inhalation therapy as the preferred route of drug administration for treating patients with chronic obstructive pulmonary disease (COPD). Inhalation devices consist of nebulizers and handheld inhalers, such as dry-powder inhalers (DPIs), pressurized metered-dose inhalers (pMDIs), and soft mist inhalers (SMIs). Although pMDIs, DPIs and SMIs may be appropriate for most patients with COPD, certain patient populations may have challenges with these devices. Patients who have cognitive, neuromuscular, or ventilatory impairments (and receive limited assistance from caregivers), as well as those with suboptimal peak inspiratory flow may not derive the full benefit from handheld inhalers. A considerable number of patients are not capable of producing a peak inspiratory flow rate to overcome the internal resistance of DPIs. Furthermore, patients may have difficulty coordinating inhalation with device actuation, which is required for pMDIs and SMIs. However, inhalation devices such as spacers and valved holding chambers can be used with pMDIs to increase the efficiency of aerosol delivery. Nebulized treatment provides patients with COPD an alternative administration route that avoids the need for inspiratory flow, manual dexterity, or complex hand-breath coordination. The recent approval of two nebulized long-acting muscarinic antagonists has added to the extensive range of nebulized therapies in COPD. Furthermore, with the availability of quieter and more portable nebulizer devices, nebulization may be a useful treatment option in the management of certain patient populations with COPD. The aim of this narrative review was to highlight recent updates and the treatment landscape in nebulized therapy and COPD. We first discuss the pathophysiology of patients with COPD and inhalation device considerations. Second, we review the updates on recently approved and newly marketed nebulized treatments, nebulized treatments currently in development, and technological advances in nebulizer devices. Finally, we discuss the current applications of nebulized therapy in patients with COPD.

Abstract
PURPOSE The Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines provide recommendations for the management of chronic obstructive pulmonary disease (COPD) exacerbation. Studies have demonstrated shortened hospital length of stay (LOS) with use of guideline-adherent systemic corticosteroid therapy. There are no published studies evaluating the impact of an inpatient orderset on patient-oriented outcomes. METHODS This institutional review board-approved, retrospective, quasi-experimental, single-center cohort study included adult patients admitted to an internal medicine service for a documented COPD exacerbation from January 2014 through December 2015 (the pre-orderset group) or January 2017 through December 2018 (the post-orderset group). A pharmacy and therapeutics committee-approved orderset recommending guideline-adherent treatment with systemic corticosteroids, scheduled short-acting bronchodilators, and antibiotics was used in the post-orderset group. The primary outcome was hospital LOS. Secondary outcomes included 30-day all-cause and COPD-related readmission rates, systemic corticosteroid-related adverse events, and antibiotic use. RESULTS A total of 358 unique patient encounters were identified for the pre-orderset group (n = 220) and post-orderset group (n = 138). The mean (SD) hospital LOS was significantly shorter in the post-orderset group (3.4 [2.4] days vs 4.3 [3.0] days; P = 0.004). There were no significant between-group differences in rates of 30-day all-cause and COPD-related readmissions. The overall rate of antibiotic use was lower in the post-orderset group vs the pre-orderset group (71% vs 90.2%; P < 0.001). The rate of occurrence of new blood glucose elevation was significantly lower in the post-orderset group (49.3% vs 79.1%; P < 0.001), with no significant between-group difference in occurrence of new blood pressure elevation. CONCLUSION A significant reduction in hospital LOS was found with the implementation of a pharmacist-driven COPD exacerbation orderset.

Abstract
PURPOSE The aim of this study was to examine the perception and preference of geriatric patients for commonly used inhaler devices in Germany. PATIENTS AND METHODS This was a prospective, open-label cross-sectional study with inpatient inhaler-naïve geriatric volunteers (age ≥ 70 years). All 106 participants were interviewed and subjected to a geriatric examination for cognitive, motor and fine motor skills before demonstrating the use of nine inhalers in random order. For each device, patients were asked to test the handling, to assess the device properties and to name the device that they would most or least prefer. RESULTS The mean age of the patients was 80.8 years. From a selection of 7 predefined general inhaler attributes, ease of use, discrete handling and inhalation resistance were the most important for the geriatric participants. Across all inhaler devices, the volunteers needed an average of 2.47 attempts to error-free use. The device with the lowest mean number of attempts was the Nexthaler® (1.75; SD ± 0.903), followed by Spiromax® (1.96; SD ± 0.965) and Genuair® (2.05; SD ± 1.027). There was a weak to moderate correlation between the number of attempts required to ensure the correct use of these three inhalers and the patient's cognitive and fine motor skills. Fifty-nine patients (56%) chose the Nexthaler as the inhalation device that they would most prefer (p<0.001 vs other devices). This was followed by Spiromax (n=23; 22%) and Genuair (n=12; 11%). The device that was least favored was the Elpenhaler® (p<0.001 vs other devices). CONCLUSION Patient preference and frequency of inhaler handling-errors may vary between inhaler devices. The Nexthaler was the easiest-to-use and most popular device among inhaler-naïve patients.

Abstract
Introduction: Chronic obstructive pulmonary disease (COPD) is a progressive condition characterized by irreversible or incompletely reversible airflow limitation. Long-acting bronchodilators, including β2 agonists (LABA) and muscarinic antagonists (LAMA), serve as the standard of care for maintenance therapy in COPD. Individualizing therapy to optimize selection of delivery device has the potential to improve medication adherence and clinical outcomes among COPD patients.Areas covered: Revefenacin (Yupelri) is the only LAMA approved for once-daily administration via standard jet nebulizer for the maintenance therapy in patients with COPD. Revefenacin has a unique biphenyl carbamate tertiary amine structure, differing from the quaternary amine structure of previously approved LAMAs. Here we summarize the available clinical data for this new agent and discuss its potential place in the treatment of COPD.Expert opinion: Based on available clinical trial data, revefenacin appears to be an effective and safe option for long-term maintenance therapy of COPD. Revefenacin offers a once-daily option for LAMA therapy for patients who prefer or require nebulized drug delivery. The availability of this agent can allow patients to combine nebulized therapies that could improve clinical outcomes in appropriately selected patients with COPD.

Abstract
Chronic obstructive pulmonary disease (COPD) can be a disabling disease, and the impact on older adults is particularly evident in the nursing home setting. Chronic obstructive pulmonary disease is present in about 20% of nursing home residents, most often in women, and accounts for significant healthcare utilization including acute care visits for exacerbations and pneumonia, as well as worsening heart disease and diabetes mellitus. The emphasis on hospital readmissions is particularly important in nursing homes where institutions have quality measures that have financial implications. Optimizing drug therapies in individuals with COPD involves choosing medications that not only improve symptoms, but also decrease the risk of exacerbations. Optimizing the treatment of comorbidities such as heart disease, infections, and diabetes that may affect COPD outcomes is also an important consideration. Depending on the nursing home setting and the patient, the options for optimizing COPD drug therapies may be limited owing to patient-related factors such as cognition and physical impairment or available resources, primarily reimbursement-related issues. Choosing the best drug therapy for COPD in older adults is limited by the difficulty in assessing respiratory symptoms using standardized assessment tools and potentially decreased inspiratory ability of frail individuals. Because of cognitive and physical impediments, ensuring optimal delivery of inhaled medications into the lungs has significant challenges. Long-acting bronchodilators, inhaled corticosteroids, and roflumilast decrease the risk of exacerbations, although inhaled corticosteroids should be used judiciously in this population because of the risk of pneumonia and oropharyngeal side effects. Treatment of COPD exacerbations should occur early and consideration should be made to the benefits and risks of systemic corticosteroids and antibiotics. Clinical research in the COPD population in nursing homes is clearly lacking, and ripe for discovery of effective management strategies.

Abstract
Introduction Inhalation devices affect both the effectiveness and the therapeutic outcomes in persistent airway obstruction, and the effects are largely independent of the drug(s) assumed. Usability is a complex and comprehensive indicator of inhalation devices’ performance. The Global Usability Score (GUS) Questionnaire is an investigational tool designed to assess objectively the patients’-related and unrelated domains of devices’ usability. Methods The GUS questionnaire was administered to all consecutive COPD patients referring for three months to the Lung Unit of CEMS Specialist Centre (Verona, Italy). The usability of seven Dry Powder Inhalers (DPIs) indicated as appropriate in COPD was tested and compared: Breezhaler, Diskus, Ellipta, Genuair, Nexthaler, Spiromax, and Turbohaler. Patients were divided in two groups, checked separately, according to their DPIs previous experience. A Bayesian Indirect Comparison (IC) model was built to assess “global usability” ranking. Results A total of 103 patients were investigated: 74 patients already instructed in DPI use and 29 naive to DPIs. IC analysis proved Ellipta as the device characterized by the highest usability, while Breezhaler the device with the lowest usability in both groups of COPD patients (both with probability > 90%). Moreover, Turbohaler ranked second according to the Bayesian pooling, followed by Diskus, Spiromax, Nexthaler, and Genuair in patients already instructed in DPI use, while the ranking order was not as much well defined in naïve patients, likely due to their too small sample. Conclusions Usability is a multifaceted indicator that contributes to assess the factual DPIs’ convenience in real life. DPIs are characterized by different levels of real-life usability, which can be checked, compared and ranked by means of the GUS score.

Abstract
Purpose: Global evidence-based treatment strategies for chronic obstructive pulmonary disease (COPD) recommend using long-acting bronchodilators (LABDs) as maintenance therapy. However, COPD patients are often undertreated. We examined COPD treatment patterns among Medicare beneficiaries who initiated arformoterol tartrate, a nebulized long-acting beta2 agonist (LABA), and identified the predictors of initiation. Methods: Using a 100% sample of Medicare administrative data, we identified beneficiaries with a COPD diagnosis (ICD-9 490-492.xx, 494.xx, 496.xx) between 2010 and 2014 who had ≥1 year of continuous enrollment in Parts A, B, and D, and ≥2 COPD-related outpatient visits within 30 days or ≥1 hospitalization(s). After applying inclusion/exclusion criteria, three cohorts were identified: (1) study group beneficiaries who received nebulized arformoterol (n=11,886), (2) a subset of the study group with no LABD use 90 days prior to initiating arformoterol (n=5,542), and (3) control group beneficiaries with no nebulized LABA use (n=220,429). Logistic regression was used to evaluate predictors of arformoterol initiation. Odds ratios (ORs), 95% confidence intervals (CIs), and p values were computed. Results: Among arformoterol users, 47% (n=5,542) had received no LABDs 90 days prior to initiating arformoterol. These beneficiaries were being treated with a nebulized (50%) or inhaled (37%) short-acting bronchodilator or a systemic corticosteroid (46%), and many received antibiotics (37%). Compared to controls, beneficiaries who initiated arformoterol were significantly more likely to have had an exacerbation, a COPD-related hospitalization, and a pulmonologist or respiratory therapist visit prior to initiation (all p<0.05). Beneficiaries with moderate/severe psychiatric comorbidity or dual-eligible status were significantly less likely to initiate arformoterol, as compared to controls (all p<0.05). Conclusion: Medicare beneficiaries who initiated nebulized arformoterol therapy had more exacerbations and hospitalizations than controls 90 days prior to initiation. Findings revealed inadequate use of maintenance medications, suggesting a lack of compliance with evidence-based treatment guidelines.

Abstract
Background: It is unknown whether the timing of initiation of a long-acting bronchodilator (LABD) during a chronic obstructive pulmonary disease (COPD) exacerbation or the method of short-acting bronchodilator (SABD) delivery may aid in improving patient outcomes. Objective: The goal of this study was to determine the impact of bronchodilator management in the hospital setting on clinical outcomes in patients with COPD exacerbation. Methods: This retrospective, single-center study evaluated patients admitted to the non-intensive care unit setting with a COPD exacerbation as defined by the International Classification of Diseases, Ninth Revision codes. The primary outcome was difference in 30-day readmission rates for early LABD therapy (<24 hours from hospital admission) versus late/no LABD therapy (>24 hours from hospital admission or not during hospitalization). Secondary objectives included length of stay (LOS) for this group, and 30-day readmission rates and LOS for the SABD via inhaler versus nebulizer groups. Results: Two hundred twenty patients were included. There was no difference in 30-day readmission rate (15.2% vs 18.2%, P = .6) and LOS (median 4 [interquartile range, IQR 3-6]) days for both groups, P = .34) between early versus late/no LABD therapy initiation, respectively. No difference was observed in 30-day readmission rate (16.7% vs 16.6%) and LOS (median 2.5 [IQR 1.1-3.9] days vs median 4 [IQR 2-6] days) between inhaler and nebulizer SABD therapy groups. Conclusions: No difference was observed in 30-day readmission rates or LOS when utilizing early LABD compared with late/no LABD therapy or comparing inhaler and nebulizer SABD delivery methods during COPD exacerbation.

Abstract
OBJECTIVES Older patients with asthma or chronic obstructive pulmonary disease are particularly susceptible to exacerbations that may be associated with incorrect use of inhalers. Educational programs with inhaler technique review seem to be effective, but no studies have addressed their cost-effectiveness in older adult patients. The objective was to perform a cost-effectiveness analysis of education programs in older patients and estimate the cost benefit of applying such a program in Portugal. DESIGN We developed a decision tree analysis from a healthcare perspective, according to intervention costs and the exacerbation rates and costs described in a previous meta-analysis. A sensitivity analysis of worst and best case scenarios was performed to estimate thresholds for intervention affordable limits, as well as cost-saving estimations and incremental cost-effectiveness ratios (ICERs) for a Portuguese scenario. SETTING AND PARTICIPANTS We estimated cost-effectiveness thresholds applicable in all settings and performed a sensitivity analysis of a theoretical intervention model in all patients including an inhaler technique review at an annual appointment with a doctor and a nurse. RESULTS In the best case scenario, the intervention affordable budget could be up to almost 1800€ (US $1585.24) per patient per year. Mean intervention-associated savings in Portugal would be 311.88€ (US $274.68) per patient per year, representing annual savings up to €131 million (US $150 million) for the whole health system, already including intervention costs. ICERs for Portugal vary between 93.73€ (US $82.55) and 437.43€ (US $385.25) per exacerbation avoided. CONCLUSION A model of an intervention program with an inhaler technique review in older adult patients suggests that this intervention is cost-effective and can generate significant savings.

Abstract
INTRODUCTION Chronic Obstructive Pulmonary Disease (COPD)and asthma affect more than 10% of the population. Most patients use their inhaler incorrectly, mainly the elderly, thereby becoming more susceptible to poor clinical control and exacerbations. Placebo device training is regarded as one of the best teaching methods, but there is scarce evidence to support it as the most effective one to improve major clinical outcomes. Our objective is to perform a single-blinded RCT to assess the impact of this education tool in these patients. METHODS AND ANALYSIS A multicentre single-blinded Randomised Controlled Trial (RCT) will be set up, comparing an inhaler education programme with a teach-to-goal placebo-device training versus usual care, with a 1-year follow-up, in patients above 65 years of age with asthma or COPD. Intervention will be provided at baseline, and after 3 and 6 months, with interim analysis at an intermediate time point. Exacerbation rates were set as primary outcomes, and quality of life, adherence rates, clinical control and respiratory function were chosen as secondary outcomes. A sample size of 146 participants (73 in each arm) was estimated as adequate to detect a 50% reduction in event rates. Two-sample proportions χ² test will be used to study primary outcome and subgroup analysis will be carried out according to major baseline characteristics. ETHICS AND DISSEMINATION Every participant will sign a written consent form. A Data Safety Monitoring Board will be set up to evaluate data throughout the study and to monitor early stopping criteria. Identity of all participants will be protected. This protocol was approved on 22 November 2017 by the local Ethics Committee of University of Beira Interior, with the reference number CE-UBI-Pj-2017-025. Results will be presented in scientific meetings and published in peer-reviewed journals. TRIAL REGISTRATION NUMBER NCT03449316; Pre-Results.

Abstract
Background Metered dose inhalers (MDIs) are commonly prescribed for inhalation therapy, but correct use is critical to promoting effective medication delivery. This systematic literature review and meta-analysis evaluates the overall and step-by-step prevalence of errors among adults with obstructive lung diseases in the United States who used MDIs. Methods Electronic and manual searches conducted between 1979-2018 using PubMed, EMBASE, PsycINFO, Cochrane, and Google identified 10 articles that met the following inclusion criteria: (a) English language, (b) U.S. adults diagnosed with chronic obstructive pulmonary disease, and (c) MDI use error rates. Meta-analytic techniques using random-effects models were applied to calculate effect sizes, weighted proportions, and 95% confidence intervals (CIs). Heterogeneity was assessed by the I2 statistic. Results Aggregate findings revealed that 86.7% of patients (n=390, 95% CI 77.5-96.0) made at least 1 inhalation technique error, and 76.9% (n=885, 95% CI 65.8-87.9) incorrectly performed ≥ 20% of device use steps. The most prevalent step-by-step errors across the studies (n=1105) were failure to: (a) exhale fully and away from the inhaler before inhalation (65.5% [95% CI 52.0, 78.9]); (b) hold breath for 5-10 seconds (41.9% [95% CI 29.8, 53.9]); (c) inhale slowly and deeply (39.4% [95% CI 26.2, 52.5]); (d) exhale after inhalation (35.9% [95% CI 17.0, 54.8]); and (e) shake the inhaler before use (34.2% [95% CI 30.6, 37.7]). Conclusions Across the studies used in this meta-analysis more than three-fourths of U.S. adults with obstructive lung diseases used MDIs incorrectly. Our findings suggest the need for ongoing patient education and consideration of alternative devices to mitigate errors.

Abstract
Background The efficacy and safety of nebulized glycopyrrolate inhalation solution (GLY), administered twice daily (BID) via the innovative eFlow® Closed System nebulizer (PARI Pharma GmbH, Starnberg, Germany), were demonstrated in two replicate, placebo-controlled, 12-week Phase III studies (GOLDEN 3 and GOLDEN 4). This report evaluates the efficacy and safety of GLY by baseline disease severity and age in the pooled GOLDEN 3 and GOLDEN 4 patient population (N=1,294). Methods Patients were grouped by baseline predicted post-bronchodilator FEV1 (<50%, ≥50%) and age (<65, ≥65, ≥75 years). Results GLY (25 and 50 μg BID) produced significant improvements in trough FEV1 in FEV1% predicted <50% (0.070 L, 0.079 L) and ≥50% (0.112 L, 0.126 L) subgroups (P<0.01 vs placebo), and in patients aged <65 (0.056 L, 0.086 L), ≥65 (0.140 L, 0.124 L), and ≥75 (0.144 L, 0.120 L) years (P<0.05 vs placebo). St George’s Respiratory Questionnaire (SGRQ) total score was significantly improved with GLY 25 and 50 μg BID (P<0.05 vs placebo) in FEV1% predicted <50% (−3.237, −3.061) and ≥50% (−3.392, −2.322) and in <65 years (−3.447, −2.318) and ≥65 years (−3.053, −3.098) subgroups. In patients aged ≥75 years, GLY 25 μg reduced SGRQ total score by −6.278 units (P<0.01 vs placebo). The incidence of treatment-emergent adverse events was similar between GLY and placebo across all subgroups, and the overall incidence of cardiovascular events was low. Conclusions Nebulized GLY improved lung function and health status and was well tolerated over 12 weeks in patients with moderate-to-very-severe COPD, irrespective of baseline disease severity and age.

Abstract
OBJECTIVES To evaluate the effect of inhaler education programs on clinical outcomes and exacerbation rates in older adults with asthma or chronic obstructive pulmonary disease (COPD). DESIGN Systematic review and meta-analysis. SETTING AND PARTICIPANTS Older adults with asthma or COPD, either in primary or secondary health care and pharmacy setting. MEASUREMENTS We searched the Medline, Embase, and Central databases according to the main eligibility criteria for inclusion: systematic reviews, meta-analysis, clinical trials and quasi-experimental studies; participants aged 65 and older; education on inhaler technique and reporting of disease control and exacerbation rates. We used the Grading of Recommendations, Assessment, Development and Evaluations scale for quality assessment and used a random-effect model with Mantel-Haenszel adjustment to perform a meta-analysis. RESULTS We included 8 studies (4 randomized, 4 quasi-experimental) with a total of 1,812 participants. The most frequent type of intervention was physical demonstration of inhaler technique, training with placebo devices. Five studies showed significant reduction in exacerbation rates (pooled risk ratio=0.71, 95% confidence interval=0.59-0.86; p < .001), although effect on disease control and quality of life showed high discrepancy in the reported results, and all randomized studies revealed uncertainty in their risk of bias assessment. CONCLUSION All interventions seemed to improve inhaler performance and clinically relevant outcomes, but a placebo device could be the most effective. There is evidence that interventions reduce exacerbation risk in older adults, although to an overall moderate degree. J Am Geriatr Soc 67:57-66, 2019.

Abstract
Pulmonary diseases, such as asthma and chronic obstructive pulmonary disease (COPD), are common in older people. Treatment principles are well established in this group of patients; however, inadequate training and improper inhaler techniques often results in poor treatment outcomes. Healthcare professionals often do not have the required knowledge about the most common inhaler devices. Age-related conditions like cognitive ability and physical strength would also impact on the inhaler usage. Pharmacokinetics and pharmacodynamics may be affected by physiological changes, like impaired renal and hepatic functions and reduced lung functions. Adjusting and optimizing the inhaler device to the patient preferences, improvement of the drug formulation and inhalers, and using different adherence strategies might improve the treatment outcomes in elderly patients.

Abstract
BACKGROUND Good compliance in chronic obstructive pulmonary disease (COPD) is of 'paramount importance' in reducing the occurrence of acute exacerbations, hospitalisation and mortality and in improving quality of life. However, a number of studies have confirmed that long-term compliance is low and often associated with difficulties in handling maintenance inhalers. Therefore, the easier an inhaler is to use, the more likely the patient will comply with handling instructions and so, optimise control of the condition. A research study was undertaken comparing the maintenance inhalers BreezhalerTM (BH-available in combination with Ultibro, Seebri and Onbrez from Novartis) and RespimatTM (RM-available in combination with Spiriva, Spiolto and Striverdi from Boehringer Ingelheim). METHODS The research was conducted among 240 maintenance inhaler-naive participants who before handling the inhalers were asked to indicate how important they felt it was that an inhaler offered each of a list of 22 handling-related attributes. They then handled each inhaler on three separate occasions familiarising themselves with the correct handling procedure by consulting respective 'Instructions for use' and short training videos. Following the handling process, participants rated the individual inhaler against each of the 22 attributes and finally expressed their preference between the two on a number of key handling-related attributes and indicated which they preferred overall. RESULTS A significant majority of participants preferred BH to RM overall. BH was rated statistically superior on 20 of the 22 handling-related attributes particularly those participants rated most highly including dosing confidence, 'easy to use' and 'easy to learn'. CONCLUSIONS Significantly more participants were confident that BH would deliver a full dose of medication and was easier to learn and use. These attributes are crucial for achieving improved patient compliance. As a result, BH offers an opportunity for improved symptom control in the maintenance treatment of COPD.

Abstract
Medication use has always played a highly significant role in the overall management of asthma, with appropriate use being linked to good asthma control. However, while patients with asthma enjoy the 'luxury' of having medications delivered directly to the lungs via inhaler devices, with that comes the additional challenge of ensuring that inhaler devices are used correctly. Research and practice provides evidence to the challenges associated with inhaler use and the particular steps that patients perform incorrectly. While this problem is well documented, acknowledged and reported, little has changed in 40 years, and the proportion of patients using inhaler devices remains unacceptably high. This review focuses on aspects specific to the errors that patient's make, the significance of these errors, and the important considerations for health care practitioners in supporting patients in correctly using their inhalers. This review highlights the complexities associated with patient's making inhaler technique errors and highlights the opportunities that lie in future technological developments of inhaler devices. Now more than ever, in the era of precision medicine, it is important that we address inhaler technique use once and for all.

Abstract
: Chronic obstructive pulmonary disease (COPD) is a prevalent and disabling disorder in the United States, especially affecting older individuals, women, and those with a history of smoking. Studies show that COPD may be underrepresented, underdiagnosed, and undertreated in elderly patients residing in long-term care (LTC) facilities. The quality of care for LTC residents with COPD is heterogeneous in regard to both the facility and the patient. For LTC facilities, care should be driven by staff education, interstaff communication, and interfacility communication. From the perspective of the LTC patient, choice of medication and device should be based on appropriate diagnosis, comorbidities, ability to perform treatment, and patient preferences. Nebulization is currently underutilized in LTC settings, although it would benefit older patients with low peak inspiratory flow, cognitive impairment, and/or physical impairment, which may preclude them from using other inhalation devices. Authors developed a COPD treatment algorithm that focuses on three primary patient aspects to consider when deciding on respiratory device in patients in LTC facilities: inspiratory flow, hand dexterity and coordination, and cognitive capacity.

Abstract
Poor inhaler technique and inferior asthma outcomes are evident in older adults. Reviews comparing metered dose inhaler (MDI) and dry powder inhaler (DPI) techniques across older adults and younger cohorts are scarce. This systematic review aimed to determine whether differences exist between such cohorts with regards to the number and type of MDI and DPI errors made. A systematic literature search was conducted in Embase, Medline and PubMed from July 1 to December 31, 2016. Studies were selected in accordance with preset inclusion criteria, relevant data were extracted, and quality was assessed with validated checklists. 14 studies were identified. Evidence suggests a negative correlation between advancing age and correct technique across MDI and varying DPI devices when examined collectively. Differences appear to exist between older adult and younger cohorts prescribed MDIs in error types. There is evidence of age-associated differences in the number and type of inhaler technique errors. Further research is required to assess outcomes in individual DPIs, reproducibility and the effects of confounders.

Abstract
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.

THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY-IN PRACTICE 2017; 4:813-20.

Abstract
The circumstances and drivers of the decision to initiate, implement, or persist with a medication differ for individuals at each developmental stage. For school-age children with asthma, the social environment of their family's cultural beliefs and the influence of peer networks and school policies are strong determinants of medication adherence. The stage of adolescence can be a particularly challenging time because there is a reduction in parental supervision of asthma management as the young person strives to become more autonomous. To illustrate the importance of such factors, adherence interventions in children and young adults with asthma have used peer-based supports and social supports, particularly social media platforms. In older patients, it is internal rather than external factors and age-related decline that pose challenges to medication adherence. Seniors face the challenges of polypharmacy, reduced social support, increased isolation, and loss of cognitive function. Strategies to promote adherence must be tailored to the developmental stage and respective behavioral determinants of the target group. This review considers the different attitudes toward medication and the different adherence behaviors in young and elderly patients with chronic respiratory conditions, specifically asthma and chronic obstructive pulmonary disease. Opportunities to intervene to optimize adherence are suggested.

Routine Use of Budesonide/Formoterol Fixed Dose Combination in Elderly Asthmatic Patients: Practical Considerations. Drugs Aging 2017; 34:321-330.

Abstract
Asthma has been demonstrated to be as common in the elderly as in younger age groups. Although no specific recommendations exist to manage the disease differently in older individuals, functional features and clinical presentations may be affected by age per se, and by age-related conditions, such as comorbidities and polypharmacy. In this review article, we aimed to explore the efficacy and safety in elderly asthmatic patients of one of the most currently used inhaled treatments for asthma, that is, the fixed-dose combination of budesonide/formoterol. We attempted to address some practical questions that are relevant to the daily practice of clinicians. We focused on the efficacy and real-world effectiveness of inhaled corticosteroids and long-acting β-adrenergic bronchodilators (ICS/LABA) as treatment in the elderly population, since data are extrapolated from younger populations. We investigated whether a maintenance and reliever therapy approach is more effective in the elderly as opposed to maintenance regimens, from both the general practitioner's and the pulmonologist's perspective. To address these questions, we scanned electronic databases (PubMed, MEDLINE, Embase, Scopus and Google Scholar) from the date of inception up to October 2016 with a cross-search using the following keywords: 'asthma', 'elderly', 'SMART therapy', 'MART therapy', 'Turbuhaler', and 'budesonide/formoterol'. The available literature on the topic confirms that when the age-associated changes are properly managed in clinical practice, asthma in older populations can be optimally controlled with inhaled treatment including ICS/LABA. This also applies for the budesonide/formoterol fixed combination, thus allowing for the maintenance and reliever therapy approach.

Abstract
Chronic obstructive pulmonary disease (COPD) is prevalent in the elderly population, with high impact on quality of life, morbidity, and mortality. The diagnosis is usually made based on symptoms and spirometry values that support the presence of airflow obstruction. However, the condition is frequently underdiagnosed. COPD is associated with premature aging and several other medical conditions that can partially explain its underdiagnosis and management. There are several pharmacologic and nonpharmacologic interventions proven to be effective in ameliorating the symptoms of COPD. Appropriate drug delivery and reduction of side effects is also pivotal in the management of patients with COPD.

Abstract
Inhaled therapies play a central role in the management of chronic obstructive pulmonary disease (COPD); however, studies indicate that many patients do not use their inhaled medication as directed, resulting in decreased medication delivery and suboptimal disease control. Key factors that should be considered when evaluating whether patients are achieving optimal outcomes with inhaled therapies are: if patients are using a correct inhalation technique; if patients have adequate dexterity to use the prescribed inhaler; if patients have sufficient inspiratory flow rate to achieve adequate lung deposition (for dry powder inhalers); and if the inhaler is accepted by the patient. There are many different types of dry powder inhalers available for COPD medications and their specific features can affect ease of use and suitability and acceptability for individual patients and patients' preferences.

Patient preferences for dry powder inhaler attributes in asthma and chronic obstructive pulmonary disease in France: a discrete choice experiment. BMC Pulm Med 2017; 17:99.

Abstract
Background Dry powder inhalers (DPIs) are often used in asthma and chronic obstructive pulmonary disease (COPD) therapies. Using the discrete choice experiment (DCE) methodology, this study conducted in France was designed to assess patients’ preferences for different attributes of DPIs. Methods Attributes of DPIs were defined based on a literature review, patient focus group discussions and interviews with healthcare professionals (qualitative phase of the study). An online survey was then conducted among French patients with asthma or COPD to elicit patient preferences and willingness to pay (WTP) for these attributes using the DCE methodology (quantitative phase). A fractional factorial design including three blocks of 12 choice sets was created. Each choice set comprised three alternatives: two fictitious inhalers and the patient’s current inhaler. Marginal utilities were estimated using a ranked ordered logit model. Interactions between attributes and disease (asthma or COPD) were tested. Results Six DPI attributes were defined based on the qualitative phase: ease of use/fool-proof priming; accurate and easy-to-read dose counter; dose confirmation; hygiene of the mouthpiece; flexibility of the device handling; ability to use the inhaler with breathing difficulties. Overall, 201 patients with asthma and 93 with COPD were included in the online survey. Patients with asthma placed most value on an inhaler that requires one step for dose preparation (WTP €4.83 [95% CI: €3.77–€5.90], relative to an inhaler requiring four steps) and one that could be used during episodes of breathing difficulties (WTP €4.49 [95% CI: €2.95–€6.02]). Patients with COPD placed most value on an inhaler that could be used during episodes of breathing difficulties (WTP €7.70 [95% CI: €5.65–€9.76]) and on the accuracy of the dose counter (WTP €5.87 [95% CI: €3.98–€ 7.77]). Conclusion This study suggests that asthma and COPD patients would be willing to change their inhaler if they were offered the option of a new inhaler with improved characteristics and they place a high value on an inhaler with ease of use during breathing difficulty episodes.

Abstract
AIM The aim of the present study was to assess the occurrence and determinants of poor adherence to pharmacological treatment in a cohort of primary care patients with chronic obstructive pulmonary disease (COPD), paying special attention to the role of age, comorbidity and polypharmacy. METHODS We identified a cohort of COPD patients using the primary care Italian Health Search - IMS Longitudinal Patient Database. We assessed 1-year adherence to COPD maintenance pharmacotherapy (encompassing inhaled corticosteroids, long-acting beta agonists and long-acting anticholinergics). Poor adherence was defined as <80% of proportion of days covered by pharmacological treatment over a 1-year period. RESULTS Of 22 505 patients (mean age 67.3 ± 13.2; 41.3% women) entering the study, 17 486 (77.7%) were poorly adherent. According to multivariate analysis, poor adherence is less likely in older adults (OR 0.51, 95% CI 0.40-0.66), in non-smokers (OR 0.77, 95% CI 0.69-0.86) and in those with a history of alcohol abuse (OR 0.74, 95% CI 0.58-0.94). Higher comorbidity (OR 1.43, 95% CI 1.13-1.80) was positively associated with poor adherence. Polypharmacy was associated with poor adherence only in patients aged ≥65 years (OR 1.34, 95% CI 1.13-1.59). Finally, COPD severity was associated with a reduced likelihood of poor adherence (OR 0.20, 95% CI 0.07-0.61 for stage IV). CONCLUSIONS The present findings show that poor medication adherence is common in patients with COPD receiving long-term treatment. The interaction between age and polypharmacy, and the role of comorbidity suggest a pivotal role of biological age as a steering determinant of poor adherence.

Instant velocity and consistency of emitted cloud change by the different levels of canister filling with Metered Dose Inhalers (MDIs), but not with Soft Mist Inhalers (SMIs): a bench study. Multidiscip Respir Med 2017; 12:13. [PMID: 28560037 PMCID: PMC5447303 DOI: 10.1186/s40248-017-0096-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2017] [Accepted: 04/26/2017] [Indexed: 12/04/2022] Open
Abstract
Background Inhalation is the preferred route for respiratory drug delivery, but several factors contribute to the variability of the respirable dose fraction. Instant velocity and the dynamic characteristics of the droplet cloud represent crucial factors. Aim was to measure and compare the instant velocity and the consistency of emitted cloud from five different MDIs (A - Salbutamol sulphate 100mcg, GSK; B - Salbutamol sulphate 100mcg, Valeas; C - Salmeterol xinafoate/Fluticasone propionate 25/125mcg, GSK; D - Formoterol fumarate/Bechlomethasone propionate 6/100mcg, Chiesi; E - Formoterol fumarate/Fluticasone dipropionate 5/125mcg, Mundipharma) and one SMI (Tiotropium bromide 5mcg, Boehringer Ingelheim), at different distance from the nozzle and canister filling. Methods Measurements were made at 90, 50, and 10% of canister filling, and at 5, 10, and 20 cm from the nozzle, for a total of 972 puffs. A high speed video photography protocol was adopted and high speed cameras (1.200 frames/sec.) were used. Data were acquired by means of specialized softwares. Temperature, humidity, and vibrations occurrence were strictly controlled during measurements. Statistics: Anova and p < 0.05 were accepted as the minimum significance level. Results MDIs generated different Instant velocities: MDI B generated the highest, while MDI A the lowest. As expected, velocity decreased in proportion to the distance from the nozzle. Except with MDI C, instant velocity decreased significantly over the first 50% of canister emptying, but dropped by >33% at 90% of emptying with all other MDIs (p < 0–037; p < 0.001; p < 0.005, and p < 0.001, respectively). Instant velocity was extremely lower (p < 0.001) and constant for all levels of canister filling (p = ns) with SMI. All MDIs had a very fast jet phase, ranging 0.01–0.03 s at 10 cm, and 0.03–0.05 s at 20 cm from the nozzle, without any significant difference from each other (p = ns). MDIs generated a cloud similarly tight (p = ns) at 10 and 20 cm from the nozzle, while it was extremely wider and constant with the SMI (p = 0–001). Also the cloud turbulence was minimized during the SMI emission. Discussion and Conclusions MDIs are characterized by a substantial variability in both their instant velocity and consistency of the emitted cloud at different levels of canister filling. SMI generates a much slower soft mist cloud which is constantly homogeneous and independent of canister emptying. These peculiarities assessed at bench are suggesting a higher dose consistency and a much more effective therapeutic performance also in real life.
