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

Background: Patients with chronic obstructive pulmonary disease (COPD) may be prescribed multiple inhalers that require different techniques for optimal performance. Mixing devices has been associated with poorer COPD outcomes suggesting that it leads to inappropriate inhaler technique. However, empirical evidence is lacking.

Is Inhaler Technique Adequately Assessed and Reported in Clinical Trials of Asthma and Chronic Obstructive Pulmonary Disease Therapy? A Systematic Review and Suggested Best Practice Checklist.

Background: Inhaled medications are central to treating asthma and chronic obstructive pulmonary disease (COPD), yet critical inhaler technique errors are made by up to 90% of patients. In the clinical research setting, recruitment of subjects with poor inhaler technique may give a false impression of both the benefits and the necessity of add-on treatments such as biologic therapies.

Objective: To assess the frequency with which inhaler technique is assessed and reliably optimized before and during patient enrollment into randomized controlled trials (RCTs) addressing the efficacy of topical therapy, and the escalation of therapy for asthma and COPD.

Inspiratory flow profile and usability of the NEXThaler, a multidose dry powder inhaler, in asthma and COPD.

Background: Inhaler selection is important when managing respiratory conditions; a patient's inhalation technique should be appropriate for the selected device, and patients should ideally be able to use a device successfully regardless of disease severity. The NEXThaler is a multidose dry-powder inhaler with a breath-actuated mechanism (BAM) and dose counter that activates only following inhalation, so effectively an 'inhalation counter'. We assessed inspiratory flow through the NEXThaler in two studies and examined whether inhalation triggered the BAM.

The clinical effectiveness of the COPDnet integrated care model.

Rationale: Integrated care models have the potential to improve outcomes for patients with COPD. We therefore designed the COPDnet integrated care model and implemented it in two hospitals and affiliated primary care regions in the Netherlands. The COPDnet model consists of a comprehensive diagnostic trajectory ran in secondary care followed by a non-pharmacological intervention program of both monodisciplinary and multidisciplinary components.

Daily Impact of COPD in Younger and Older Adults: Global Online Survey Results from over 1,300 Patients.

The daily impact of chronic obstructive pulmonary disease (COPD) on younger patients is often underappreciated. To assess this, we investigated the disease burden experienced by younger and older patients. A panel of questions was developed in conjunction with the European Federation of Allergy and Airways Diseases Patients' Associations and Boehringer Ingelheim.

Spacer devices for inhaled therapy: why use them, and how?

We present an extensive review of the literature to date pertaining to the rationale for using a spacer/valved holding chamber (VHC) to deliver inhaled therapy from a pressurised, metered-dose inhaler, a discussion of how the properties of individual devices may vary according to their physical characteristics and materials of manufacture, the potential risks and benefits of ancillaries such as valves, and the evidence that they contribute tangibly to the delivery of therapy. We also reiterate practical recommendations for the correct usage and maintenance of spacers/VHCs, which we trust offer practical help and advice to patients and healthcare professionals alike.

Proactive palliative care for patients with COPD (PROLONG): a pragmatic cluster controlled trial.

Background And Aim: Patients with advanced chronic obstructive pulmonary disease (COPD) have poor quality of life. The aim of this study was to assess the effects of proactive palliative care on the well-being of these patients.

Trial Registration: This trial is registered with the Netherlands Trial Register, NTR4037.

Development of the ProPal-COPD tool to identify patients with COPD for proactive palliative care.

Background: Our objective was to develop a tool to identify patients with COPD for proactive palliative care. Since palliative care needs increase during the disease course of COPD, the prediction of mortality within 1 year, measured during hospitalizations for acute exacerbation COPD (AECOPD), was used as a proxy for the need of proactive palliative care.

Patients And Methods: Patients were recruited from three general hospitals in the Netherlands in 2014.

Budesonide + formoterol delivered via Spiromax for the management of asthma and COPD: The potential impact on unscheduled healthcare costs of improving inhalation technique compared with Turbuhaler.

Background: Fixed-dose combinations of inhaled corticosteroids and long-acting β agonists are commonly used for the treatment of asthma and COPD. However, the most frequently prescribed dry powder inhaler delivering this medicine - Symbicort (budesonide and formoterol, BF) Turbuhaler - is associated with poor inhalation technique, which can lead to poor disease control and high disease management costs. A recent study showed that patients make fewer inhaler errors when using the novel DuoResp (BF) Spiromax inhaler, compared with BF Turbuhaler.

Inhaler technique mastery and maintenance in healthcare professionals trained on different devices.

Objective: Healthcare professionals (HCPs) are required to assess and train patients in the correct use of inhalers but are often unable to demonstrate correct technique themselves. We sought to assess the level of training required for HCPs to master and maintain device mastery when using two different dry powder inhalers (DPIs).

Methods: We conducted a randomized, un-blinded, crossover study in undergraduate HCPs who undertook a six-step training procedure (intuitive use, patient information leaflet, instructional video, individual tuition from expert, then two repeats of individual tuition) for the use of Turbuhaler® (an established device) and Spiromax® (a newer device, reportedly easier to use).

Adaptation of a difficult-to-manage asthma programme for implementation in the Dutch context: a modified e-Delphi.

Patients with difficult-to-manage asthma represent a heterogeneous subgroup of asthma patients who require extensive assessment and tailored management. The International Primary Care Respiratory Group approach emphasises the importance of differentiating patients with asthma that is difficult to manage from those with severe disease. Local adaptation of this approach, however, is required to ensure an appropriate strategy for implementation in the Dutch context.

The view of pulmonologists on palliative care for patients with COPD: a survey study.

Introduction: Early palliative care is not a common practice for patients with COPD. Important barriers are the identification of patients for palliative care and the organization of such care in this patient group.

Objective: Pulmonologists have a central role in providing good quality palliative care for patients with COPD.

'To use or not to use': a qualitative study to evaluate experiences of healthcare providers and patients with the assessment of burden of COPD (ABC) tool.

In the management of chronic conditions, such as chronic obstructive pulmonary disease (COPD), there is a shift from doctor-driven care to patient-centred integrated care with active involvement of and self-management by the patient. A recently developed tool, the assessment of burden of COPD (ABC) tool, can be used in this transition to facilitate self-management support and shared decision-making. We performed a qualitative study, in which we collected and analysed the data using the methods of conventional content analyses.

Incidence of oral thrush in patients with COPD prescribed inhaled corticosteroids: Effect of drug, dose, and device.

Background And Aims: Little information is available on real-life occurrence of oral thrush in COPD patients treated with ICS. We investigated oral thrush incidence in COPD patients prescribed FDC ICS/LABA therapies and assessed whether it is modulated by the ICS type, dose, and delivery device.

Methods: We conducted a historical, observational, matched cohort study (one baseline year before and one outcome year after initiation of therapy) using data from the UK Optimum Patient Care Research Database.

[Effectiveness of the Assessment of Burden of COPD tool: a cluster-randomised controlled trial].

Objective: Assessment of the effectiveness of the Assessment of Burden of COPD (ABC) tool on disease-specific quality of life in patients with Chronic Obstructive Pulmonary Disease (COPD).

Design: Cluster-randomised controlled trial.

Method: This concerned a trial in 39 Dutch primary care practices and 17 hospitals, involving 357 patients with COPD (postbronchodilator FEV1/FVC ratio < 0.

Respiratory constraints during activities in daily life and the impact on health status in patients with early-stage COPD: a cross-sectional study.

In patients with chronic obstructive pulmonary disease (COPD), exercise capacity is reduced, resulting over time in physical inactivity and worsened health status. It is unknown whether ventilatory constraints occur during activities of daily life (ADL) in early stages of COPD. The aim of this study was to assess respiratory mechanics during ADL and to study its consequences on dyspnoea, physical activity and health status in early-stage COPD compared with healthy controls.

Development of a diagnostic decision tree for obstructive pulmonary diseases based on real-life data.

The aim of this study was to develop and explore the diagnostic accuracy of a decision tree derived from a large real-life primary care population. Data from 9297 primary care patients (45% male, mean age 53±17 years) with suspicion of an obstructive pulmonary disease was derived from an asthma/chronic obstructive pulmonary disease (COPD) service where patients were assessed using spirometry, the Asthma Control Questionnaire, the Clinical COPD Questionnaire, history data and medication use. All patients were diagnosed through the Internet by a pulmonologist.

Patients' perspectives and preferences in the choice of inhalers: the case for Respimat(®) or HandiHaler(®).

Poor inhaler technique hampers the efficacy of drug therapy in asthma and chronic obstructive pulmonary disease. Not only does this affect individual patient care, but it also impacts on the wider health care economics associated with these conditions. Treatment guidelines recommend a systematic approach to drug class selection; however, standardization of inhaler selection is currently difficult owing to the complexity of the interaction between the inhaler device and the patient.

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.

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 β2 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.

Effectiveness of the Assessment of Burden of COPD (ABC) tool on health-related quality of life in patients with COPD: a cluster randomised controlled trial in primary and hospital care.

Objective: Assessing the effectiveness of the Assessment of Burden of COPD (ABC) tool on disease-specific quality of life in patients with chronic obstructive pulmonary disease (COPD) measured with the St. George's Respiratory Questionnaire (SGRQ), compared with usual care.

Methods: A pragmatic cluster randomised controlled trial, in 39 Dutch primary care practices and 17 hospitals, with 357 patients with COPD (postbronchodilator FEV1/FVC ratio <0.

Inhaler technique: facts and fantasies. A view from the Aerosol Drug Management Improvement Team (ADMIT).

Health professionals tasked with advising patients with asthma and chronic obstructive pulmonary disease (COPD) how to use inhaler devices properly and what to do about unwanted effects will be aware of a variety of commonly held precepts. The evidence for many of these is, however, lacking or old and therefore in need of re-examination. Few would disagree that facilitating and encouraging regular and proper use of inhaler devices for the treatment of asthma and COPD is critical for successful outcomes.
