Estimating the effectiveness of pulmonary rehabilitation for COPD exacerbations: reduction of hospital inpatient days during the following year.

AIMS: To study the short- and long-term results of pulmonary rehabilitation (PR) given in the Helsinki University Heart and Lung Center and to understand the hospital resources used to treat severe COPD exacerbations in the city of Helsinki. MATERIALS AND METHODS: Seventy-eight inactive patients with severe COPD were recruited for a PR course; three of them did not finish the course. The course took 6-8 weeks and included 11-16 supervised exercise sessions. Using electronic medical records, we studied all COPD patients with hospital admission in the city of Helsinki in 2014, including COPD diagnosis, criteria for exacerbation, and potential exclusion/inclusion criteria for PR. RESULTS: Seventy-five of the patients finished the PR course and 92% of those patients showed clinically significant improvement. Their hospital days were reduced by 54% when compared to the year before. At 1 year after the course, 53% of the patients reported that they have continued with regular exercise training. In the city of Helsinki, 437 COPD patients were treated in a hospital due to exacerbation during 2014. On the basis of their electronic medical records, 57% of them would be suitable for PR. According to a rough estimate, 10%-20% hospital days could be saved annually if PR was available to all, assuming that the PR results would be as good as those shown here. CONCLUSIONS: The study showed that in a real-world setting, PR is efficient when measured by saved hospital days in severe COPD. Half of the patients could be motivated to continue exercising on their own.

Individual FEV1 Trajectories Can Be Identified from a COPD Cohort.

OBJECTIVE: We aim to make use of clinical spirometry data in order to identify individual COPD-patients with divergent trajectories of lung function over time. STUDY DESIGN AND SETTING: Hospital-based COPD cohort (N = 607) was followed on average 4.6 years. Each patient had a mean of 8.4 spirometries available. We used a Hierarchical Bayesian Model (HBM) to identify the individuals presenting constant trends in lung function. RESULTS: At a probability level of 95%, one third of the patients (180/607) presented rapidly declining FEV1 (mean -78 ml/year, 95% CI -73 to -83 ml) compared to that in the rest of the patients (mean -26 ml/year, 95% CI -23 to -29 ml, p ≤ 2.2 × 10(-16)). Constant improvement of FEV1 was very rare. The rapid decliners more frequently suffered from exacerbations measured by various outcome markers. CONCLUSION: Clinical data of unique patients can be utilized to identify diverging trajectories of FEV1 with a high probability. Frequent exacerbations were more prevalent in FEV1-decliners than in the rest of the patients. The result confirmed previously reported association between FEV1 decline and exacerbation rate and further suggested that in clinical practice HBM could improve the identification of high-risk individuals at early stages of the disease.

Physical activity in COPD patients decreases short-acting bronchodilator use and the number of exacerbations.

BACKGROUND: Physically inactive patients with chronic obstructive pulmonary disease (COPD) exhibit higher rates of exacerbations and symptoms of dyspnoea than active patients. Whether the use of COPD medication explains these differences is not known. AIM: This study evaluated differences in the use of COPD medication and the number of exacerbations due to physical activity. METHODS: A COPD cohort (N = 719) was followed through medical records to identify hospital admissions, and exercise activity was evaluated using mailed questionnaires. The national drug reimbursement registry identified drug purchases for one year. RESULTS: The use of maintenance therapies, such as long-acting muscarinic antagonists (LAMAs), long-acting beta agonists (LABAs), inhaled corticosteroids (ICS), and theophylline, did not differ significantly between physically active (N = 346) and inactive (N = 355) COPD patients. The cumulative dose of salbutamol (85 vs. 218 mg, adjusted P = 0.01) and oral corticosteroids (OCS) (621 vs. 1068 mg, adjusted P = 0.02) were significantly higher in inactive patients, regardless of disease severity. LABAs, LAMAs, and ICS were used in reduced doses in both patient groups compared to daily defined doses (DDD). Physical activity was independently associated with the number of hospital admissions and the use of OCS and short-acting bronchodilators. CONCLUSION: Physical inactivity in COPD was not associated with poorer use of maintenance therapies. In contrast, inactivity was independently associated with the number of exacerbations measured by hospital admissions and the use of OCS and short-acting symptom-relieving medications.

Diagnosis and pharmacotherapy of stable chronic obstructive pulmonary disease: the finnish guidelines.

The Finnish Medical Society Duodecim initiated and managed the update of the Finnish national guideline for chronic obstructive pulmonary disease (COPD). The Finnish COPD guideline was revised to acknowledge the progress in diagnosis and management of COPD. This Finnish COPD guideline in English language is a part of the original guideline and focuses on the diagnosis, assessment and pharmacotherapy of stable COPD. It is intended to be used mainly in primary health care but not forgetting respiratory specialists and other healthcare workers. The new recommendations and statements are based on the best evidence available from the medical literature, other published national guidelines and the GOLD (Global Initiative for Chronic Obstructive Lung Disease) report. This guideline introduces the diagnostic approach, differential diagnostics towards asthma, assessment and treatment strategy to control symptoms and to prevent exacerbations. The pharmacotherapy is based on the symptoms and a clinical phenotype of the individual patient. The guideline defines three clinically relevant phenotypes including the low and high exacerbation risk phenotypes and the neglected asthma-COPD overlap syndrome (ACOS). These clinical phenotypes can help clinicians to identify patients that respond to specific pharmacological interventions. For the low exacerbation risk phenotype, pharmacotherapy with short-acting ß2 -agonists (salbutamol, terbutaline) or anticholinergics (ipratropium) or their combination (fenoterol-ipratropium) is recommended in patients with less symptoms. If short-acting bronchodilators are not enough to control symptoms, a long-acting ß2 -agonist (formoterol, indacaterol, olodaterol or salmeterol) or a long-acting anticholinergic (muscarinic receptor antagonists; aclidinium, glycopyrronium, tiotropium, umeclidinium) or their combination is recommended. For the high exacerbation risk phenotype, pharmacotherapy with a long-acting anticholinergic or a fixed combination of an inhaled glucocorticoid and a long-acting ß2 -agonist (budesonide-formoterol, beclomethasone dipropionate-formoterol, fluticasone propionate-salmeterol or fluticasone furoate-vilanterol) is recommended as a first choice. Other treatment options for this phenotype include combination of long-acting bronchodilators given from separate inhalers or as a fixed combination (glycopyrronium-indacaterol or umeclidinium-vilanterol) or a triple combination of an inhaled glucocorticoid, a long-acting ß2 -agonist and a long-acting anticholinergic. If the patient has severe-to-very severe COPD (FEV1  < 50% predicted), chronic bronchitis and frequent exacerbations despite long-acting bronchodilators, the pharmacotherapy may include also roflumilast. ACOS is a phenotype of COPD in which there are features that comply with both asthma and COPD. Patients belonging to this phenotype have usually been excluded from studies evaluating the effects of drugs both in asthma and in COPD. Thus, evidence-based recommendation of treatment cannot be given. The treatment should cover both diseases. Generally, the therapy should include at least inhaled glucocorticoids (beclomethasone dipropionate, budesonide, ciclesonide, fluticasone furoate, fluticasone propionate or mometasone) combined with a long-acting bronchodilator (ß2 -agonist or anticholinergic or both).

[Update on current care guideline: chronic obstructive pulmonary disease (COPD)]. / Keuhkoahtaumatauti.

Clinical serverity of COPD is based not only on the grade of obstruction in spirometry, but also on symptoms and risk of exacerbations. Symptoms can be defined by questionnaires, such as CAT-test (COPD assessment -test) or mMRC (modified Medical Research Council -test). Smoking cessation and physical activity are important treatment options. Pharmacological treatment is selected by symptoms, risk of exacerbations and co-occurrence of asthma and COPD. Non-invasive ventilation (NIV) is recommended in the treatment of severe hypercapnic exacerbations. Palliative treatment of end stage COPD is included in the guidelines.

[Endobronchial ultrasonography--when needed?]. / Keuhkoputkien kaikutähystys--milloin tarpeen?

Endobronchial ultrasonography (EBUS) and associated needle biopsy is a mini-invasive means to study mediastinal and hilar lymph nodes and tumors. Guidance by real-time ultrasound image allows the biopsy of even small targets with high accuracy. The investigation is well tolerated, highly specific and its main indication is the staging of lung cancer. The method is also suitable for primary diagnosis of mediastinal lymphadenopathy of unknown origin or central tumors.

Physical inactivity in COPD and increased patient perception of dyspnea.

OBJECTIVE: To study patients' levels of exercise activity and the clinical characteristics that relate to physical activity and inactivity among patients with chronic obstructive pulmonary disease (COPD). METHODS: A postal questionnaire was administered to 719 patients with COPD in 2010; patients were recruited from the Helsinki and Turku University Central Hospitals in Finland and have been followed since 2005. The questionnaire asked participants about their exercise routines and other daily activities, potential restrictions to exercise, health-related quality of life, and subjective sensations of dyspnea upon exertion. RESULTS: A total of 50% of the participants reported exercising>2 times a week throughout the year. The proportion of the exercise inactive patients increased in parallel with disease progression, but the participants exhibited great variation in the degree of activity as well as in sport choices. Year-round activity was better maintained among patients who exercised both indoors and outdoors. Training activity was significantly correlated with patients' reported subjective dyspnea (r=0.32, P<0.001), health-related quality of life (r=0.25, P<0.001), mobility score (r=0.37, P<0.001), and bronchial obstruction (r=0.18, P<0.001). Active patients did not differ from inactive patients in terms of sex, age, smoking status, somatic comorbidities, or body mass index. Irrespective of the level of severity of patients' COPD, the most significant barrier to exercising was the subjective sensation of dyspnea. CONCLUSION: When a patient with COPD suffers from dyspnea and does not have regular exercise routines, the patient will most likely benefit from an exercise program tailored to his or her physical capabilities.
