- Background: Guideline recommendations for chronic obstructive pulmonary disease (COPD) are based on the results of large pharmaceutically-sponsored COPD studies (LPCS). There is a paucity of data on disease characteristics at the primary care level, while the majority of COPD patients are treated in primary care. Objective: We aimed to evaluate the external validity of six LPCS (ISOLDE, TRISTAN, TORCH, UPLIFT, ECLIPSE, POET-COPD) on which current guidelines are based, in relation to primary care COPD patients, in order to inform future clinical practice guidelines and trials. Methods: Baseline data of seven primary care databases (n = 3508) from Europe were compared to baseline data of the LPCS. In addition, we examined the proportion of primary care patients eligible to participate in the LPCS, based on inclusion criteria. Results: Overall, patients included in the LPCS were younger (mean difference (MD)-2.4; p = 0.03), predominantly male (MD 12.4; p = 0.1) with worse lung function (FEV1% MD -16.4; p < 0.01) and worse quality of life scores (SGRQ MD 15.8; p = 0.01). There were large differences in GOLD stage distribution compared to primary care patients. Mean exacerbation rates were higher in LPCS, with an overrepresentation of patients with >= 1 and >= 2 exacerbations, although results were not statistically significant. Our findings add to the literature, as we revealed hitherto unknown GOLD I exacerbation characteristics, showing 34% of mild patients had >= 1 exacerbations per year and 12% had >= 2 exacerbations per year. The proportion of primary care patients eligible for inclusion in LPCS ranged from 17% (TRISTAN) to 42% (ECLIPSE, UPLIFT). Conclusion: Primary care COPD patients stand out from patients enrolled in LPCS in terms of gender, lung function, quality of life and exacerbations. More research is needed to determine the effect of pharmacological treatment in mild to moderate patients. We encourage future guideline makers to involve primary care populations in their recommendations.

- Background: Few studies have investigated the 24-hour symptom profile in patients with COPD or how symptoms during the 24-hour day are inter-related. This observational study assessed the prevalence, severity and relationship between night-time, early morning and daytime COPD symptoms and explored the relationship between 24-hour symptoms and other patient-reported outcomes. Methods: The study enrolled patients with stable COPD in clinical practice. Baseline night-time, early morning and daytime symptoms (symptom questionnaire), severity of airflow obstruction (FEV1), dyspnoea (modified Medical Research Council Dyspnoea Scale), health status (COPD Assessment Test), anxiety and depression levels (Hospital Anxiety and Depression Scale), sleep quality (COPD and Asthma Sleep Impact Scale) and physical activity level (sedentary, moderately active or active) were recorded. Results: The full analysis set included 727 patients: 65.8% male, mean +/- standard deviation age 67.2 +/- 8.8 years, % predicted FEV1 52.8 +/- 20.5%. In each part of the 24-hour day, > 60% of patients reported experiencing >= 1 symptom in the week before baseline. Symptoms were more common in the early morning and daytime versus night-time (81.4%, 82.7% and 63.0%, respectively). Symptom severity was comparable for each period assessed. Overall, in the week before baseline, 56.7% of patients had symptoms throughout the whole 24-hour day (3 parts of the day); 79.9% had symptoms in >= 2 parts of the 24-hour day. Symptoms during each part of the day were inter-related, irrespective of disease severity (all p < 0.001). Early morning and daytime symptoms were associated with the severity of airflow obstruction (p < 0.05 for both). Nighttime, early morning and daytime symptoms were all associated with worse dyspnoea, health status and sleep quality, and higher anxiety and depression levels (all p < 0.001 versus patients without symptoms in each corresponding period). In each part of the 24-hour day, there was also an association between symptoms and a patient's physical activity level (p < 0.05 for each period). Conclusions: More than half of patients experienced COPD symptoms throughout the whole 24-hour day. There was a significant relationship between night-time, early morning and daytime symptoms. In each period, symptoms were associated with worse patient-reported outcomes, suggesting that improving 24-hour symptoms should be an important consideration in the management of COPD.

The International Primary Care Respiratory Group (IPCRG) Research Needs Statement 2010

- 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.

Forskningsöversikt (refereegranskat)abstract
- Current guidelines recommend chronic obstructive pulmonary disease (COPD) management based on symptoms or health status assessment and lung function parameters. However, COPD is a complex and heterogeneous disease that needs an individualized approach for proper disease management. A structured consultation including health status assessment tools, such as the Clinical COPD Questionnaire and the COPD Assessment Test should improve the quality of the consultation, providing more information than symptoms alone. Both questionnaires are designed to provide the clinician information enabling a more personalized disease approach and subsequent management. Although both Clinical COPD Questionnaire and COPD Assessment Test have good discriminate properties, their use as prognostic markers of severity and their ability to modify disease management has not yet been fully established. New studies are needed to further determine their value on several disease outcomes.
