The economic burden of asthma and chronic obstructive pulmonary disease and the impact of poor inhalation technique with commonly prescribed dry powder inhalers in three European countries

Contains fulltext : 171713.pdf (publisher's version ) (Open Access)BACKGROUND: Asthma and chronic obstructive pulmonary disease (COPD) are common chronic inflammatory respiratory diseases, which impose a substantial burden on healthcare systems and society. Fixed-dose combinations (FDCs) of inhaled corticosteroids (ICS) and long-acting beta2 agonists (LABA), often administered using dry powder inhalers (DPIs), are frequently prescribed to control persistent asthma and COPD. Use of DPIs has been associated with poor inhalation technique, which can lead to increased healthcare resource use and costs. METHODS: A model was developed to estimate the healthcare resource use and costs associated with asthma and COPD management in people using commonly prescribed DPIs (budesonide + formoterol Turbuhaler((R)) or fluticasone + salmeterol Accuhaler((R))) over 1 year in Spain, Sweden and the United Kingdom (UK). The model considered direct costs (inhaler acquisition costs and scheduled and unscheduled healthcare costs), indirect costs (productive days lost), and estimated the contribution of poor inhalation technique to the burden of illness. RESULTS: The direct cost burden of managing asthma and COPD for people using budesonide + formoterol Turbuhaler((R)) or fluticasone + salmeterol Accuhaler((R)) in 2015 was estimated at euro813 million, euro560 million, and euro774 million for Spain, Sweden and the UK, respectively. Poor inhalation technique comprised 2.2-7.7 % of direct costs, totalling euro105 million across the three countries. When lost productivity costs were included, total expenditure increased to euro1.4 billion, euro1.7 billion and euro3.3 billion in Spain, Sweden and the UK, respectively, with euro782 million attributable to poor inhalation technique across the three countries. Sensitivity analyses showed that the model results were most sensitive to changes in the proportion of patients prescribed ICS and LABA FDCs, and least sensitive to differences in the number of antimicrobials and oral corticosteroids prescribed. CONCLUSIONS: The cost of managing asthma and COPD using commonly prescribed DPIs is considerable. A substantial, and avoidable, contributor to this burden is poor inhalation technique. Measures that can improve inhalation technique with current DPIs, such as easier-to-use inhalers or better patient training, could offer benefits to patients and healthcare providers through improving disease outcomes and lowering costs

Does mixing inhaler devices lead to unchecked inhaler technique errors in patients with COPD? : Findings from the cross-sectional observational MISMATCH study

Funding Information: The members of the MISMATCH study group would like to acknowledge Titia Klemmeijer (founder of the IMIS foundation; 'Inhalatie Medicatie Instruction School') for her assistance in formulating the list of additional errors, and Chantal Arling, Thomas le Rutte & Landy Torre for their time and efforts to perform the reassessments of the video recordings. Finally, they would like to thank the participants who generously gave their time to participate in the PIFotal study and provided informed consent to use their video/data for future research. This work was supported by Chiesi Pharmaceuticals. The PIFotal study was cofunded by Boehringer Ingelheim.Peer reviewe
