Background and aim Early detection enables the possibility for interventions to reduce the future burden of COPD. The Danish National Board of Health recommends that individuals >35 years with tobacco/occupational exposure, and at least 1 respiratory symptom should be offered a spirometry to facilitate early detection of COPD. The aim, therefore, was to provide evidence for the feasibility and impact of doing spirometry in this target population. Methods Participating general practitioners (GPs) (n = 335; 10% of the Danish GPs) recruited consecutively, subjects with >35 years exposure, no previous diagnosis of obstructive lung disease, and at least 1 of the following symptoms: cough, dyspnea, wheezing, sputum, or recurrent respiratory infection. Data on age, smoking status, pack-years, body mass index (BMI), dyspnea score (Medical Research Council, MRC), and pre-bronchodilator spirometry (FEV1, FEV1% predicted, FEV1/FVC) were obtained. Results A total of 3.095 (51% females) subjects was included: mean age 58 years, BMI 26.3, and 31.5 pack-years. The majority of subjects (88%) reported MRC score 1 or 2. FEV1/FVC-ratio ≤ 0.7 was found in 34.8% of the subjects; the prevalence of airway obstruction increased with age and decreased with increasing BMI, and was higher in men and current smokers. According to the level of FEV1, 79% of the subjects with airway obstruction had mild to moderate COPD. Conclusions More than one-third of the recruited subjects had airway obstruction (FEV1/ FVC < 0.7). Early detection of COPD appears to be feasible through offering spirometry to adults with tobacco/occupational exposure and at least 1 respiratory symptom.

Abstract Background and Aim: Under-diagnosis of COPD is a widespread problem. This study aimed to identify previously undiagnosed cases of COPD in a high-risk population identified through general practice. Methods: Participating GPs (n = 241) recruited subjects with no previous diagnosis of lung disease, >35 yrs, and at least one respiratory symptom. Age, smoking status, pack-years, BMI, dyspnoea score (MRC), and pre-bronchodilator spirometry data was obtained. Subjects with airway obstruction (FEV1/FVC ≤ 0.7) at initial spirometry were tested for reversibility, according to Danish COPD guidelines, with bronchodilator and, if necessary, corticosteroids in order to confirm a diagnosis of COPD. Results: A total of 4.049 (49% females) subjects were included; mean age 58 yrs, BMI 27, and 32 pack-years. The COPD prevalence was 21.7%; 8.3% in subjects younger than 48 years. Most patients were classified in GOLD stages I and II (36% and 50%, respectively). The number needed to screen (NNS) for a new diagnosis of COPD was 4.6. COPD diagnosis was related to gender, age, BMI (p < 0.001), pack-years, and cough (p < 0.001), wheezing (p < 0.001) and sputum production (p = 0.002). A threshold of 10% pre-test risk of COPD would have reduced the number of spirometry tests by 35% although 90% of the patients with COPD would still have been identified (NNS 3.9). Conclusions: Of the at-risk subjects studied, 22% were diagnosed with COPD. A case-finding strategy providing questionnaire assessment and diagnostic spirometry to high-risk subjects in primary care, and therefore, identifies a large proportion of undiagnosed COPD patients, especially in the early stages of the disease.

Background and aim: The general practitioner (GP) is the first contact with the health care system for most patients with COPD in Denmark. We studied, if participating in an educational program could improve adherence to guidelines, not least for diagnosis, staging, and treatment of the disease. Design and setting: Two cross-sectional surveys were performed precisely one year apart before and after an educational program for the participating GPs. A total of 124 GPs completed the study; 1716 and 1342 patients with GP-diagnosed COPD and no concomitant asthma, respectively, were included in the two surveys. Results: The proportion of patients having FEV1 registered in the GPs files increased from 45% to 69% (P < 0.001); and, furthermore, FEV1 % of predicted was recorded in 30% and 56%, respectively, of the cases (P < 0.001). In line with this, significant improvements were also observed for registration of smoking status (69% to 85%), BMI (8% to 40%), severity of dyspnea (Medical Research Council) (7% to 38%), and FEV1/FVC ratio (28% to 58%) (P < 0.001). Concerning the management options, improvements were also observed with regard to antismoking counseling, inhalator technique, physical activity, and referral for rehabilitation; use of inhaled corticosteroids in patients with mild COPD (FEV1 > 80%pred) declined from 76% to 45%. Conclusion: Diagnosis and management of COPD in general practice in Denmark is not according to guidelines, but substantial improvements can be achieved by focused education of GPs and their staff.

BACKGROUND We studied the quality of care for COPD patients in 22 hospital-based outpatient clinics in Denmark and evaluated if participation by the staff in an educational programme could improve the quality of care and adherence to the COPD guidelines. METHODS We performed two audits of the hospital records one year apart before and after the educational programme for the participating doctors and nurses. A total of 941 patient records were included in the first audit and 927 in the second. The indicators of quality of care comprised amongst others referral to pulmonary rehabilitation, smoking cessation advice, nutritional advice, instruction in inhalation technique and assessment of BMI, smoking status, pack years, lung function parameters, dyspnoea oxygen saturation and co-morbidities. RESULTS In general, the quality of care for COPD patients in Denmark was suboptimal and not in accordance with the recently published guidelines both in the 1st and the 2nd audit. Yet, we observed a substantial improvement from the 1st to the 2nd audit. For example, referral to rehabilitation improved from 56.3 to 62.7% (p=0.006) Assessment of BMI improved from 7.8 to 56.1% and assessment of dyspnoea using MRC dyspnoea scale increased from 7.2 to 47.2% (both p<0.001). When analysing the results with focus on the performance of the individual outpatient clinics we also observed an improvement in the quality. CONCLUSION We conclude that it is possible to improve the quality of care for COPD by focusing on a more systematic approach to the patient assessment by education of the staff of the outpatient clinics. A repeated and continuous education and discussion with the clinical staff is probably essential to reach an acceptable level of the quality of care for outpatients with COPD.

Is a percentage a percentage? Systematic review of the effectiveness of Scandinavian behavioural modification smoking cessation programmes.

Peter Bo Poulsen; Jens Dollerup; Ann Merete Møller

Introduction:  Tobacco smoke is the leading preventable cause of death in the world. A total of 50% of all smokers will die from a smoking‐related disease with a major impact upon quality of life and health‐care costs. Tobacco‐controlling policies, including smoking cessation, have increasingly been implemented across European countries. Reported effectiveness data on smoking cessation interventions are important for decision making.

Study on drug costs associated with COPD prescription medicine in Denmark

Marie Jakobsen; Niels Anker; Jens Dollerup; Peter Bo Poulsen; Peter Lange

Spirometric studies of the general population estimate that 430 000 Danes have chronic obstructive pulmonary disease (COPD). COPD is mainly caused by smoking, and smoking cessation is the most important intervention to prevent disease progression. Cost‐of‐illness studies conclude that the costs associated with COPD in Denmark are significant, but costs of prescription medicine for COPD were not analysed.

Up to 436,000 adult Danes suffer from chronic obstructive pulmonary disease (COPD), with only one third diagnosed at this time. The Danish National Board of Health recommends early detection of COPD, focusing on smokers/ex-smokers over 35 years of age with at least one lung symptom. A governmental prevention committee has suggested that the municipalities, in addition to general practice, should be a potential arena responsible for early detection of COPD. We undertook a pilot study to investigate the feasibility and effectiveness of early detection of COPD in municipalities following the recommendations of the Danish National Board of Health. Methods The Municipality of Esbjerg offered spirometry to Danish citizens at risk of COPD without a previous diagnosis of the disease, following the National Board of Health’s recommendations. Citizens with evidence of airway obstruction (forced expiratory volume in one second [FEV1]/forced vital capacity [FVC] <70%) were advised to visit their general practitioner for diagnosis. These citizens were followed up by telephone interview 3 months later. Results Of 152 citizens sampled (50% females, mean age 58 years, 51% smokers) 51.3% had evidence of airway obstruction, with 87% being mild to moderate in terms of severity. Seven of ten citizens (71%) then visited their general practitioner, with 85% of these being diagnosed with COPD. The number of smokers embarking on smoking cessation or quitting smoking increased following COPD screening, with the highest frequency in participants with evidence of airway obstruction. Conclusion In addition to early detection of COPD in general practice, early detection of airway obstruction in defined risk populations in Danish municipalities seems feasible and effective for identifying new patients with COPD. However, additional research is needed in larger samples to confirm the results of the present study.

ABSTRACT Background: Although chronic obstructive pulmonary disease (COPD) is one of the leading causes of morbidity and mortality globally, several studies have shown little awareness of COPD in the general population. The awareness of COPD in the Scandinavian countries is, however, sparsely investigated. Objective: The aim of this study was to explore the awareness in the general Danish population of smoking-related health risks and symptoms related to COPD and attitudinal factors concerning smoking. Design: Adults aged 18 years or older were randomly selected to reflect the background population. An Internet-based questionnaire was conducted in January–February 2015. Results: A total of 1002 answered the questionnaire (515 males; 487 females). In total, 17.7% were current smokers (men: 15.5%–women: 19.9%). More smokers and ex-smokers knew the symptoms of COPD compared to never-smokers (p < 0.001). Ex-smokers had undergone more pulmonary function tests than smokers and never-smokers (p < 0.001) and significantly more men than women who had undergone pulmonary function test. Ex-smokers were more likely to rate cancer as the most feared disease (p = 0.026) than the smokers. Of the smokers, 28% did not regard COPD as a deadly disease and significantly more smokers than ex-/never-smokers believed that smoking cessation should not be mandatory before treatment of COPD and asthma (p < 0.001). Conclusion: Overall, smokers, ex-, and never-smokers had little knowledge of COPD regarding aetiology, symptoms, and severity thus emphasizing the necessity of early detection of COPD and more focus on spirometry in general practice, especially amongst smokers. There is a great discrepancy between the attitude of smokers and ex-/never-smokers towards mandatory smoking cessation before receiving treatment of smoking-related diseases.

Ulla Hemmingsen; Margit Stycke; Jens Dollerup; Peter Bo Poulsen

Background. Early detection of chronic obstructive pulmonary disease (COPD) and prevention of disease progression are important. Only 40% of COPD cases are diagnosed in Denmark. Recommendations for early case finding have been established. This study investigates early detection of pulmonary obstruction in a Danish municipality setting. Methods. Eight municipalities participated. Citizens fulfilling national case finding recommendations, age ≥35 years, smokers/ex-smokers/relevant occupational exposure, and at least one respiratory symptom, were invited to spirometry. Citizens with indication of pulmonary obstruction, forced expiratory volume in one second (FEV1)/forced vital capacity (FVC) < 0.70, were referred to their general practitioner (GP). Results. 1,499 citizens were examined (53.6% male, mean age 57.2 years). 44.8% were current smokers with 57% planning for smoking cessation. The citizens recorded significant airway symptoms with dyspnea being the most important (71%). The mean FEV1/FVC score was 73.54 (SD 22.84). 456 citizens (30.4%) were found to have indication for pulmonary obstruction and were referred to GP for further diagnosis. Conclusion. Early detection in Danish municipalities proved effective finding nearly 1/3 being pulmonary obstructive. It seems to be of value to have municipalities to perform case finding together with smoking cessation as a primary intervention in COPD management.
