- Factors related to the discrepancy between patient-perceived and actual disease control remain unclear. Identifying patients at risk of overestimation of asthma control remains elusive. This study aimed to (i) investigate the relationship between patient-reported and actual level of asthma control (ii), compare the characteristics between patients who believe their asthma is well controlled that accurately report 'well-controlled' asthma with those that do not, and (iii) identify factors associated with inaccurately reported 'well-controlled' asthma. A historical, multinational, cross-sectional study using data from the iHARP (initiative Helping Asthma in Real-life Patients) review service for adults with asthma prescribed fixed-dose combination therapy. Data from 4274 patients were analysed. A major discrepancy between patient-reported and Global Initiative for Asthma defined asthma control was detected; 71.1% of patients who reported 'well-controlled' asthma were inaccurate in their perception despite receiving regular maintenance therapy. Significant differences were noted in age, gender, body mass index, education level, medication use, side effects, attitudes to preventer inhaler use, inhaler technique review and respiratory specialist review between patients who accurately reported 'wellcontrolled' asthma and those who did not. Independent risk factors associated with inaccurately reported 'well-controlled' asthma were: having taken a maximum of 5-12 puffs or more of reliever inhaler on at least one day within the previous 4 weeks; being female; having seen a respiratory specialist more than a year ago (rather than in the previous year); and having required oral corticosteroids for worsening asthma in the previous year. The study highlighted the significant hidden burden associated with under-recognition of poor asthma control, on the part of the patient and the need for targeted interventions designed to address the continuing discrepancy between perceived and actual disease control.

- Purpose: There is a dearth of research regarding the prevalence and nature of patient-reported rhinitis and its relationship with risk of asthma exacerbations. The aim of this study was to (i) determine the prevalence, severity and treatment of self-reported rhinitis symptoms among adults aged >= 18 years with asthma treated at Global Initiative for Asthma (GINA) Step 3 and above and (ii) compare the demographics, clinical characteristics, medication use, side-effects and healthcare practitioner review between patients who report rhinitis symptoms and those who do not and (iii) determine whether patient-reported rhinitis is associated with risk of asthma exacerbations in the total patient sample. Patients and Methods: This analysis used data from the iHARP (Initiative Helping Asthma in Real-life Patients) asthma review service - a cross-sectional observational study (2011 and 2014) in seven countries that captured data on patient demographics, rhinitis symptoms, asthma symptoms, indicators of exacerbations, medication use, oropharyngeal effects and side-effects, using practitioner- and patient-reported questionnaires. Comparisons between patients with and without rhinitis were tested. Univariate logistic regression was used to identify variables associated with risk of exacerbations for entry into multivariable logistic regression. Results: This report contains data from 4274 patients: 67.4% (2881/4274) reported rhinitis symptoms and of which 65.7% (1894/2881) had not received a doctor diagnosis; 36.5% (1052/2881) had moderate-severe rhinitis, 12.4% (358/2881) had used intranasal corticosteroids and 19.8% (569/2881) oral antihistamines. Patients with coexisting moderate-severe rhinitis were more likely to have GINA-defined uncontrolled asthma than those with mild rhinitis or no rhinitis. Moderate-severe rhinitis was associated with 40% increased risk of asthma exacerbations (OR=1.40, 95% CI: 1.02-1.90). Conclusion: This study identified a major gap in the diagnosis and management of rhinitis in a cohort of people with asthma treated at GINA Step 3 and above who are managed in general practice. It highlights the need for practitioners to identify, evaluate and optimally treat rhinitis in adults with asthma, which is a significant factor associated with exacerbation risk.

- AIM: Respiratory diseases are a public health issue throughout the world, with high prevalence and morbidity. This Research Needs Statement from the International Primary Care Respiratory Group (IPCRG) aims to highlight unanswered questions on the management of respiratory diseases that are of importance to practising primary care clinicians. METHODS: An informal but inclusive consultation process was instigated in 2009. Draft statements in asthma, rhinitis, COPD, tobacco dependence, and respiratory infections were circulated widely to IPCRG members, other recognised experts, and representatives from a range of economic and healthcare backgrounds. An iterative process was used to generate, prioritise and refine research questions in each section. RESULTS: Two overarching themes emerged. Firstly, there is a real need for research to be undertaken within primary care, which recruits patients representative of primary care populations, evaluates interventions realistically delivered within primary care, and draws conclusions that will be meaningful to professionals working within primary care. Secondly, international and national guidelines exist, but there is little evidence on the best strategies for implementing recommendations. Disease-specific research questions focus on effective and cost-effective ways to prevent disease, confirm the diagnosis, assess control, manage treatment, and empower selfmanagement. Practical questions about how to deliver this comprehensive agenda in diverse primary care settings are highlighted. CONCLUSIONS: We hope that this Research Needs Statement will be used by clinicians and patients campaigning for answers to relevant questions, by researchers seeking funding to provide answers to these questions, and by funding bodies to enable them to prioritise research agendas.

- BACKGROUND: Poor inhaler technique has been linked to poor asthma outcomes. Training can reduce the number of inhaler errors, but it is unknown which errors have the greatest impact on asthma outcomes.OBJECTIVE: The CRITical Inhaler mistaKes and Asthma controL study investigated the association between specific inhaler errors and asthma outcomes.METHODS: This analysis used data from the iHARP asthma review service-a multicenter cross-sectional study of adults with asthma. The review took place between 2011 and 2014 and captured data from more than 5000 patients on demographic characteristics, asthma symptoms, and inhaler errors observed by purposefully trained health care professionals. People with asthma receiving a fixed-dose combination treatment with inhaled corticosteroids and long-acting beta agonist were categorized by the controller inhaler device they used-dry-powder inhalers or metered-dose inhalers: inhaler errors were analyzed within device cohorts. Error frequency, asthma symptom control, and exacerbation rate were analyzed to identify critical errors.RESULTS: This report contains data from 3660 patients. Insufficient inspiratory effort was common (made by 32%-38% of dry-powder inhaler users) and was associated with uncontrolled asthma (adjusted odds ratios [95% CI], 1.30 [1.08-1.57] and 1.56 [1.17-2.07] in those using Turbohaler and Diskus devices, respectively) and increased exacerbation rate. In metered-dose inhaler users, actuation before inhalation (24.9% of patients) was associated with uncontrolled asthma (1.55 [1.11-2.16]). Several more generic and device-specific errors were also identified as critical.CONCLUSIONS: Specific inhaler errors have been identified as critical errors, evidenced by frequency and association with asthma outcomes. Asthma management should target inhaler training to reduce key critical errors.

- Objective: Correct inhaler technique is central to effective delivery of asthma therapy. The study aim was to identify factors associated with serious inhaler technique errors and their prevalence among primary care patients with asthma using the Diskus dry powder inhaler (DPI).Methods: This was a historical, multinational, cross-sectional study (2011-2013) using the iHARP database, an international initiative that includes patient- and healthcare provider-reported questionnaires from eight countries. Patients with asthma were observed for serious inhaler errors by trained healthcare providers as predefined by the iHARP steering committee. Multivariable logistic regression, stepwise reduced, was used to identify clinical characteristics and asthma-related outcomes associated with 1 serious errors.Results: Of 3681 patients with asthma, 623 (17%) were using a Diskus (mean [SD] age, 51 [14]; 61% women). A total of 341 (55%) patients made 1 serious errors. The most common errors were the failure to exhale before inhalation, insufficient breath-hold at the end of inhalation, and inhalation that was not forceful from the start. Factors significantly associated with 1 serious errors included asthma-related hospitalization the previous year (odds ratio [OR] 2.07; 95% confidence interval [CI], 1.26-3.40); obesity (OR 1.75; 1.17-2.63); poor asthma control the previous 4 weeks (OR 1.57; 1.04-2.36); female sex (OR 1.51; 1.08-2.10); and no inhaler technique review during the previous year (OR 1.45; 1.04-2.02).Conclusions: Patients with evidence of poor asthma control should be targeted for a review of their inhaler technique even when using a device thought to have a low error rate.
