          To assess clinical characteristics and device satisfaction of patients with chronic obstructive pulmonary disease (COPD) treated with glycopyrrolate/eFlow ® Closed System (CS) nebulizer (further referred to as eFlow) under real-world conditions.

          Participants and Methods

          Patients with COPD currently using eFlow were identified by the study sponsor. Consenting patients who met study inclusion criteria completed a cross-sectional survey that included a device satisfaction questionnaire. Means, medians, and standard deviations were calculated.


          Sixty-six patients met inclusion criteria and completed the survey. Participants’ mean ± standard deviation age was 64.9 ± 11.9 years and the majority were white (86.4%) and female (59.1%). Almost two-thirds were former smokers. Thirty-nine (59.1%) reported their COPD to be severe/very severe and 38 (57.6%) reported a COPD exacerbation resulting in a hospitalization, ER visit, or medication modification over the past 12 months. Among 55 participants who had previously used another type of nebulizer, 44 (80%) were overall “much more”/“somewhat more” satisfied with the eFlow compared with their previous nebulizer(s). Regardless of prior nebulizer use, 60 (90.9%) participants were “satisfied”/“very satisfied” overall with the eFlow. Assembly and disassembly, operation, and cleaning were perceived as being “easy”/“very easy” by at least 65% of participants. Among all participants, 57 (86.4%) were “confident”/“very confident” of glycopyrrolate administration. On a Likert scale of 1 (“I don’t like it”) to 7 (“I like it a lot”), mean scores were at least 5.9 for portability, ease of cleaning, size, weight, short administration time, and relative silence of the device. Over 80% of participants said they “probably”/"definitely" would continue to use eFlow.


          Based on this real-world study, the majority of patients were highly satisfied with, and confident in, using eFlow.

          Impact of patients' satisfaction with their inhalers on treatment compliance and health status in COPD.

          To examine the relationships between inhaler satisfaction, treatment compliance and health status in patients with chronic obstructive pulmonary disease (COPD). In a large, multinational, cross-sectional, real-world survey, respiratory specialists and primary care physicians provided information on six consecutive patients with COPD, who were then asked to complete a questionnaire. Physician-assessed compliance was scored (5-point Likert scale) and patients rated overall satisfaction with their maintenance inhaler (7-point Likert scale). Health status assessments included frequency of exacerbations and hospitalizations due to exacerbations in the past 12 months. The analysis included 1443 patients (71.8% male; mean age 65.2 years). Patients' overall satisfaction with their inhaler was significantly associated with treatment compliance (χ(2) - df = 89.7; p < 0.001). Male gender (χ(2) - df = 2.9; p < 0.05) and fewer maintenance drugs (χ(2) - df = 17.7; p < 0.001) were also associated with compliance; age and breathlessness severity were not. Attributes influencing inhaler satisfaction mainly related to durability, ergonomics and ease of use. Small but statistically significant associations were observed between increasing treatment compliance and fewer exacerbations (R(2) = 0.037; p < 0.001) and fewer hospitalizations due to exacerbations (R(2) = 0.025; p < 0.001). There was a direct association between inhaler satisfaction and fewer exacerbations (R(2) = 0.03; p < 0.001). Treatment compliance appears to be modestly associated with inhaler satisfaction, better health status and less frequent COPD exacerbations, although other factors are also likely to be involved. Durability, ergonomics and ease-of-use are inhaler attributes that influence patient satisfaction. Copyright © 2013 Elsevier Ltd. All rights reserved.

            Patient preferences for inhaler devices in chronic obstructive pulmonary disease: experience with Respimat® Soft Mist™ Inhaler

            Current guidelines for the management of chronic obstructive pulmonary disease (COPD) recommend the regular use of inhaled bronchodilator therapy in order to relieve symptoms and prevent exacerbations. A variety of inhaler devices are currently available to COPD patients, and the choice of device is an important consideration because it can influence patients’ adherence to treatment, and thus potentially affect the long-term outcome. The Respimat® Soft Mist™ Inhaler (SMI) generates a slow-moving aerosol with a high fine particle fraction, resulting in deposition of a higher proportion of the dose in the lungs than pressurized metered-dose inhalers (pMDIs) or some dry powder inhalers (DPIs). We review clinical studies of inhaler satisfaction and preference comparing Respimat® SMI against other inhalers in COPD patients. Using objective and validated patient satisfaction instruments, Respimat® SMI was consistently shown to be well accepted by COPD patients, largely due to its inhalation and handling characteristics. In comparative studies with pMDIs, the patient total satisfaction score with Respimat® SMI was statistically and clinically significantly higher than with the pMDI. In comparative studies with DPIs, the total satisfaction score was statistically significantly higher than for the Turbuhaler® DPI, but only the performance domain of satisfaction was clinically significantly higher for Respimat® SMI. Whether the observed higher levels of patient satisfaction reported with Respimat® SMI might be expected to result in improved adherence to therapy and thus provide benefits consistent with those recently shown to be associated with sustained bronchodilator treatment in patients with COPD remains to be proven.

              Optimizing drug delivery in COPD: The role of inhaler devices.

              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.
