Objective sputum colour assessment and clinical outcomes in bronchiectasis: data from the European Bronchiectasis Registry (EMBARC).

BACKGROUND: A validated 4-point sputum colour chart can be used to objectively evaluate the levels of airway inflammation in bronchiectasis patients. In the European Bronchiectasis Registry (EMBARC), we tested whether sputum colour would be associated with disease severity and clinical outcomes. METHODS: We used a prospective, observational registry of adults with bronchiectasis conducted in 31 countries. Patients who did not produce spontaneous sputum were excluded from the analysis. The Murray sputum colour chart was used at baseline and at follow-up visits. Key outcomes were frequency of exacerbations, hospitalisations for severe exacerbations and mortality during up to 5-year follow-up. RESULTS: 13 484 patients were included in the analysis. More purulent sputum was associated with lower forced expiratory volume in 1 s (FEV1), worse quality of life, greater bacterial infection and a higher bronchiectasis severity index. Sputum colour was strongly associated with the risk of future exacerbations during follow-up. Compared to patients with mucoid sputum (reference group), patients with mucopurulent sputum experienced significantly more exacerbations (incident rate ratio (IRR) 1.29, 95% CI 1.22-1.38; p<0.0001), while the rates were even higher for patients with purulent (IRR 1.55, 95% CI 1.44-1.67; p<0.0001) and severely purulent sputum (IRR 1.91, 95% CI 1.52-2.39; p<0.0001). Hospitalisations for severe exacerbations were also associated with increasing sputum colour with rate ratios, compared to patients with mucoid sputum, of 1.41 (95% CI 1.29-1.56; p<0.0001), 1.98 (95% CI 1.77-2.21; p<0.0001) and 3.05 (95% CI 2.25-4.14; p<0.0001) for mucopurulent, purulent and severely purulent sputum, respectively. Mortality was significantly increased with increasing sputum purulence, hazard ratio 1.12 (95% CI 1.01-1.24; p=0.027), for each increment in sputum purulence. CONCLUSION: Sputum colour is a simple marker of disease severity and future risk of exacerbations, severe exacerbations and mortality in patients with bronchiectasis.

Prevalence and management of severe asthma in the Nordic countries: findings from the NORDSTAR cohort.

Background: Real-life evidence on prevalence and management of severe asthma is limited. Nationwide population registries across the Nordic countries provide unique opportunities to describe prevalence and management patterns of severe asthma at population level. In nationwide register data from Sweden, Norway and Finland, we examined the prevalence of severe asthma and the proportion of severe asthma patients being managed in specialist care. Methods: This is a cross-sectional study based on the Nordic Dataset for Asthma Research (NORDSTAR) research collaboration platform. We identified patients with severe asthma in adults (aged ≥18 years) and in children (aged 6-17 years) in 2018 according to the European Respiratory Society/American Thoracic Society definition. Patients managed in specialist care were those with an asthma-related specialist outpatient contact (only available in Sweden and Finland). Results: Overall, we identified 598 242 patients with current asthma in Sweden, Norway and Finland in 2018. Among those, the prevalence of severe asthma was 3.5%, 5.4% and 5.2% in adults and 0.4%, 1.0%, and 0.3% in children in Sweden, Norway and Finland, respectively. In Sweden and Finland, 37% and 40% of adult patients with severe asthma and two or more exacerbations, respectively, were managed in specialist care; in children the numbers were 56% and 41%, respectively. Conclusion: In three Nordic countries, population-based nationwide data demonstrated similar prevalence of severe asthma. In children, severe asthma was a rare condition. Notably, a large proportion of patients with severe asthma were not managed by a respiratory specialist, suggesting the need for increased recognition of severe asthma in primary care.

Effectiveness of inhalation technique assessment service for patients with Respimat® inhaler.

OBJECTIVES: The objective of this study was to examine how Inhalation Technique Assessment Service (ITAS) by community pharmacies affect patients' inhalation techniques when using the Respimat® soft mist inhaler. The inhaler was simultaneously updated into a reusable inhaler. The study focused on the Respimat® inhaler because its use is known to be challenging for patients. METHODS: The study was performed as a pre-post design in 33 community pharmacies (CPs) in Finland. Patients' inhalation technique was assessed before ITAS (baseline) and immediately after ITAS (follow-up 1). Follow-up 2 was performed when the patient came to the pharmacy for a refill (1-3 months after the baseline and the follow-up 1). A Respimat specific twenty item checklist was used to assess inhalation technique. The checklist included 1) preparation steps before the first use of the Respimat® inhaler (8 items) and 2) daily use steps of the Respimat® inhaler (12 items). After ITAS, the patients received a brief questionnaire to assess their asthma/COPD history. RESULTS: A total of 228 patients were enrolled at the first visit (mean age 67.8 years, 61.0% female, 85.5% had previous Respimat® use experience) and 42 of them attended the follow-up 2, 1-3 months later (mean age 70.1 years, 69.0% female, 92.9% had previous Respimat® use experience. The median number of the steps performed correctly increased from 17/20 at the baseline to all the 20 steps at the follow-up 1 (p < 0.001). At the baseline, 27.6% of the patients (n = 228) performed all preparation steps correctly, while 87.3% at the follow-up 1 and 71.4% at the follow-up 2. The percentage of the patients with acceptable inhalation technique (all critical daily use steps correct) increased from 69.7% at the baseline to 93.0% at the follow-up 1 (p < 0.001). The corresponding figure at the follow-up 2 was 69.0%. At the baseline, 30.3% of patients had optimal inhalation technique (all daily use steps correct). At the follow-up 1 corresponding figure was 85.1%, and 54.8% at the follow-up 2. CONCLUSIONS: A pharmacist-led intervention significantly improved asthma and COPD patients' inhalation technique with the Respimat® inhaler. Significant improvements were found in the daily use steps and the preparation steps before the first use.

The Finnish Allergy Program 2008-2018: Society-wide proactive program for change of management to mitigate allergy burden.

A 10-year national program to improve prevention and management of allergic diseases and asthma was implemented in Finland (population 5.5. million) in 2008-2018. The main aim was to reduce the long-term burden of these conditions. The strategy was changed from traditional avoidance to tolerance and resilience of the population. Health was endorsed instead of medicalization of mild symptoms. Disease severity was reevaluated, and disabling clinical manifestations were given high priority. For health care, 5 quantitative goals and 1 qualitative goal were set. For each of the goals, specific tasks, tools, and outcome evaluation were stipulated. During the program, 376 educational sessions gathered 24,000 health care participants. An information campaign targeted the lay public, and social media was used to contact people. In the 10 years of the program, the prevalence of allergic diseases and asthma leveled off. Asthma caused fewer symptoms and less disability, and 50% fewer hospital days. Food allergy diets in day care and schools decreased by half. Occupational allergies were reduced by 45%. In 2018, the direct and indirect costs of allergic diseases and asthma ranged from €1.5 billion to €1.8 billion, with the 2018 figures being 30% less than in the respective figures in 2007. The Finnish proactive and real-world intervention markedly reduced the public health burden of allergic disorders. The allergy paradigm was revisited to improve management with systematic education.

Multimorbidity in Asthma, Allergic Conditions and COPD Increase Disease Severity, Drug Use and Costs: The Finnish Pharmacy Survey.

BACKGROUND: Asthma, allergic conditions, and COPD overlap, but the effect of them and their combinations on disease severity, need for drugs, use of healthcare, and costs is poorly known. OBJECTIVE: To study how different allergic diseases co-occur in asthma and allergy patients and evaluate the use of medication well as drug and healthcare costs. METHODS: Nationwide Allergy Barometer Survey was carried out in the Finnish pharmacies during 1 week in September 2016. Altogether, 956 patients (5-75 years) who purchased asthma or allergy drugs with prescription participated in 351 pharmacies. RESULTS: Of the participants, 78% reported physician-diagnosed asthma, 57% allergic rhinitis, 24% atopic eczema, 21% food allergy, 20% allergic conjunctivitis, 8% anaphylaxis, and 8% COPD. One-third of the patients had at least three conditions, and multimorbidity was common across all age groups. Disease severity increased with the number of coexisting conditions, and asthma severity also with age. Patients with asthma alone used on average 3.8 drugs with the annual costs of EUR 661. This increased to 4.9 drugs and EUR 847 in asthmatics with multimorbidity. For all participants, costs of drugs and healthcare services together during the preceding year were on average EUR 1,214, of which 56% were drug costs. The costs doubled to EUR 2,714 in 65 subjects (7%) who had both asthma and COPD. CONCLUSIONS: In asthma and allergy, multimorbidity and polypharmacy are major concerns. Disease severity, drug use, and costs increased with multimorbid conditions. To reduce the burden, allergy management should be better integrated and more comprehensive.

Nordic consensus statement on the systematic assessment and management of possible severe asthma in adults.

Although a minority of asthma patients suffer from severe asthma, they represent a major clinical challenge in terms of poor symptom control despite high-dose treatment, risk of exacerbations, and side effects. Novel biological treatments may benefit patients with severe asthma, but are expensive, and are only effective in appropriately targeted patients. In some patients, symptoms are driven by other factors than asthma, and all patients with suspected severe asthma ('difficult asthma') should undergo systematic assessment, in order to differentiate between true severe asthma, and 'difficult-to-treat' patients, in whom poor control is related to factors such as poor adherence or co-morbidities. The Nordic Consensus Statement on severe asthma was developed by the Nordic Severe Asthma Network, consisting of members from Norway, Sweden, Finland, Denmark, Iceland and Estonia, including representatives from the respective national respiratory scientific societies with the aim to provide an overview and recommendations regarding the diagnosis, systematic assessment and management of severe asthma. Furthermore, the Consensus Statement proposes recommendations for the organization of severe asthma management in primary, secondary, and tertiary care.

Chronic Comorbidities Contribute to the Burden and Costs of Persistent Asthma.

BACKGROUND: We aimed to study the prevalence of chronic comorbidities in asthma patients and the costs of health care use associated with asthma with comorbidities. MATERIAL AND METHODS: We analysed the prevalence of the four most common chronic diseases in asthma patients in 2008-2014 in Finland. Prevalence of coronary artery disease, diabetes and dyslipidaemia, hypertension, epilepsy, inflammatory bowel disease, rheumatic diseases, and severe psychiatric disease was studied by register of the Social Insurance Institution of Finland. The costs of health care services were collected from the registries maintained by the National Institute for Health and Welfare (THL). RESULTS: Prevalence of asthma was 4.6% in 2014. Diabetes was among the four most common comorbidities in all the age groups. The other common comorbidities were hypertension (≥46 years; 12.9-37.6%), severe psychiatric disorders (age groups of 16-59 years; 1.4-3.5%), and ischaemic heart disease (≥60 years; 10-25%). In patients with both asthma and diabetes, the costs of hospitalization were approximately 169% compared with patients with asthma alone. CONCLUSIONS: Prevalence of asthma increases by tenfold when aging. The comorbidity diversity and rate are age-dependent. Prevalence of diabetes as comorbidity in asthma has increased. Costs of hospitalizations in asthma approximately double with chronic comorbidities.

Follow-up of the Finnish Asthma Programme 2000-2010: reduction of hospital burden needs risk group rethinking.

The Finnish Asthma Programme 1994-2004 focused on early intervention and disease control, thereby resulting in a significant reduction of asthma morbidity. During the follow-up period from 2000 to 2010, the number of hospital days continued to fall by 54%. Patients ≥65 years, especially women, accounted for 39% of the hospital days, and they need attention if the hospital burden is to be reduced further.

Allergic rhinitis alone or with asthma is associated with an increased risk of sickness absences.

The aim of the study is to examine the risk of sickness absence in public sector employees with allergic rhinitis or asthma or both conditions combined. This is a prospective cohort study of 48,296 Finnish public sector employees. Data from self-reported rhinitis and asthma were obtained from survey responses given during either the 2000-2002 or 2004 periods. Follow-up data on sickness absences for the public sector employees surveyed were acquired from records kept by the employers. During the follow-up, mean sick leave days per year for respondents were 17.6 days for rhinitis alone, 23.8 days for asthma alone and 24.2 days for both conditions combined. Respondents with neither condition were absent for a mean of 14.5 days annually. The impact of asthma and rhinitis combined on the risk of sick leave days was marginal compared to asthma alone (RR 1.1; 95% CI 1.0-1.3). In the subgroup analysis (those with current asthma or allergy medication), the risk ratio for medically certified sickness absence (>3 days) was 2.0 (95% CI 1.9-2.2) for those with asthma and rhinitis combined. Rhinitis, asthma and both these conditions combined increased the risk of days off work.
