Previous studies have found suboptimal control of symptom burden to be widespread among patients with asthma and chronic obstructive pulmonary disease (COPD). The Phase IV SPRINT study was conducted in 10 countries in Europe to assess asthma disease control and COPD symptom burden in patients treated with a fixed-dose combination (FDC) of inhaled corticosteroids (ICS) and long-acting beta agonists (LABAs). SPRINT included 1101 patients with asthma and 560 with COPD; all were receiving treatment with an FDC of ICS/LABA, delivered via various inhalers. Data were obtained over a 3-month period, during a single routine physician’s office visit. Asthma control was defined as Asthma Control Test (ACT) score >19. COPD symptom burden was assessed by COPD Assessment Test (CAT), with a CAT score <10 defining low COPD symptom burden. Among patients using any ICS/LABA FDC, 62% of patients with asthma had achieved disease control (ACT score >19) and 16% of patients with COPD had low symptom burden (CAT score <10).
While poor inhaler technique in asthma and chronic obstructive pulmonary disease (COPD) can compromise the effectiveness of inhaled medications, identifying and quantifying these errors may suggest ways to improve inhalation technique and patient outcomes. The objective of this international, multicentre care improvement programme was to investigate errors in inhaler use (handling errors and inhalation errors) made by patients in handling two dry powder inhalers; DuoResp® Spiromax® and Symbicort® Turbuhaler®. Patients with asthma or COPD aged between 18 and 80 years attending the allergology/pneumology departments of 14 hospitals in Spain and Portugal were included. All assessments were performed during one regular scheduled visit to the study clinic. Among 161 eligible patients (138 with asthma; 23 with COPD), inhalation errors were the most common type of error, with no significant difference between devices in overall total error rate, handling error rate or inhalation error rate. Significantly fewer total errors per patient (1.4 vs. 1.9; p < 0.001) and handling errors per patient (0.5 vs. 0.8; p < 0.001) were observed with DuoResp® Spiromax® compared with Symbicort® Turbuhaler®. The mean number of attempts for patients using DuoResp® Spiromax® to perform two correct procedures was 1.9 (0.6) compared with 2.1 (0.9) attempts for patients using Symbicort® Turbuhaler® ( p = 0.016). Compared with Symbicort® Turbuhaler®, DuoResp® Spiromax® was found to be easy to learn how to use ( p < 0.001), easy to prepare ( p < 0.001), easy to use ( p < 0.001), comfortable in terms of weight and size ( p = 0.001), and patients felt that they were using the device correctly ( p < 0.001). Overall, 79.5% of patients stated that they preferred DuoResp® Spiromax® as their first option over Symbicort® Turbuhaler®. The findings of this study may be useful in developing effective inhaler training programmes and thus improve outcomes in asthma and COPD.
Purpose: To assess the effectiveness of additional risk minimization measures (aRMMs) implemented in Europe for colistimethate sodium (CMS) among healthcare professionals (HCPs) and patients/caregivers following safety concerns regarding incorrect use of CMS delivered via Turbospin inhaler. Methods:A cross-sectional study was conducted among HCPs and patients/caregivers in . Knowledge of the educational materials was assessed regarding common side effects, correct use of CMS and Turbospin inhaler, and capsule breakage. Awareness, receipt, and utilization of the aRMMs were also evaluated. Results: Among 124 HCPs surveyed, the majority acknowledged awareness (86.2%), receipt (91.0%), and utilization (81.6%) of the CMS educational materials and were knowledgeable about the common CMS side effects (93.2%). Most HCPs correctly answered most questions regarding the proper use of CMS (>90%), yet only half knew how to correctly use the Turbospin inhaler (53.2%). Knowledge about capsule breakage was moderate (67.5%). Of the 29 patients/caregivers surveyed, almost half were aware of the educational materials (48.1%); of these, 69.2% received and used the materials. Most patients/caregivers were knowledgeable about the common CMS side effects (81.5%) and proper CMS use (>85%); however, knowledge about correct Turbospin inhaler use and potential for capsule breakage was moderate to low (48.1% and 37.9%, respectively). Conclusions: HCPs and patients/caregivers have good knowledge about the common side effects associated with CMS. However, knowledge of correct use of the Turbospin inhaler and capsule breakage was moderate to low.

Objective: Adherence and inhaler technique are often suboptimal in asthma and chronic obstructive pulmonary disease (COPD). New inhalers have been developed to improve these determinants of treatment effectiveness. We assessed treatment adherence, satisfaction, and ease of use of DuoResp V R Spiromax V R among SPRINT study participants. Methods: The Phase IV SPRINT study was conducted in 10 European countries. Asthma and COPD patients were receiving a fixed-dose combination of inhaled corticosteroid (ICS) and long-acting b 2 -agonist (LABA), delivered via various inhalers including DuoResp Spiromax. DuoResp Spiromax users self-assessed adherence using the 8-item Morisky Medication Adherence Scale (MMAS-8 V R ), and ease of use and satisfaction using 10-point scales, during a single physician's office visit. Results: Of 1661 (asthma: n ¼ 1101; COPD: n ¼ 560) SPRINT study participants, 342 (asthma: n ¼ 235; COPD: n ¼ 107) received DuoResp Spiromax prior to inclusion. Overall, 72.5% of DuoResp Spiromax users reported medium or high adherence (MMAS-8 score !6). Mean (standard deviation [SD]) satisfaction score for DuoResp Spiromax was 8.9 (1.6). Almost all (98.8%) DuoResp Spiromax users were at least satisfied with their inhaler; 85.4% were very satisfied. Mean (SD) ease of use score for DuoResp Spiromax was 9.1 (1.3). Conclusions: Asthma and COPD patients using DuoResp Spiromax reported moderate-tohigh medication adherence, were very satisfied with their inhaler and found it easy to use.
