- Background Dry powder inhaler (DPI) device switch in asthma treatment could potentially increase with the entrance of new devices. We examined the switch patterns of budesonide (BUD) DPI analogues available in Sweden. Methods This observational real-life study linked primary healthcare medical records data from the Västra Götaland region to national Swedish registries, and included asthma patients (ICD-10-CM J45) prescribed BUD in a multidose DPI. Index date: first dispense of BUD DPI. Switch date: prescription of another BUD DPI device. Study outcomes (switch vs. non-switch) were exacerbations and prescription of short-acting β2-agonists. Study period was 1 July 2005 to 31 October 2013. Results Overall, 15,169 asthma patients were on treatment with BUD DPI; 1178 (7.35%) switched to another BUD DPI during the study. Pair-wise 1:1 matching of switchers vs. non-switchers resulted in two groups of 463 patients each (mean age 36 years, 55% female patients). A 25% higher exacerbation rate was seen postswitch (0.40 vs. 0.32; p = 0.047). Switchers were 4.5 year younger and had lower medication possession rate than non-switchers. Switch without primary healthcare visit did not differ between groups regarding consultations and exacerbations (no visit 4.96 and 0.90; visit 4.29 and 0.77, respectively). However, patients without primary healthcare visit at switch had significantly more outpatient hospital visits (2.01 vs. 0.81; p < 0.001). Conclusions Considering the low switch rate, asthma patients and physicians in Swedish general practice seem reluctant to switch to another BUD DPI device. Switch, especially without primary healthcare visit, was associated with decreased asthma control resulting in higher exacerbation rate and more outpatient hospital visits. © 2015 John Wiley & Sons Ltd.

- Objective: Although asthma and chronic obstructive pulmonary disease (COPD) have been regarded as distinct conditions, emerging literature suggests that overlapping phenotypes, called asthma-COPD overlap (ACO), exists. The aim of this study was to describe prevalence, patient characteristics and morbidity of ACO. Methods: From a cross-sectional population sample, the West Sweden Asthma Study, subjects with suspected asthma, chronic bronchitis or COPD, and a random sample, were invited to clinical examinations. ACO was defined as doctor-diagnosed asthma, or clear clinical signs of asthma at examination, with a FEV1/FVC < 0.7. Results: Subjects were categorized as ACO (N = 181), COPD only (N = 89), asthma only (N = 651) or healthy (n = 1036) based on clinical examinations. Prevalence of ACO was 3.4% in the random sample (N = 1172) and 18.1% among asthmatics (N = 138) in the random sample. Subjects with ACO (mean age 59 years, 54% women) had an age and gender distribution in between asthma only (45 years, 63% women) and COPD only (62 years, 41% women). Ever-smoking was reported by 71%, 48% and 74% in the ACO, asthma only and COPD only groups, respectively. Subjects with ACO had worse lung function (mean FEV1% of predicted normal 76%) than asthma only (100%) and COPD only (87%) and reported more respiratory symptoms. Also respiratory related emergency visits were more common in ACO compared to asthma only and COPD only, respectively. Conclusions: ACO is present in 3.4% of the population and common among subjects with both asthma and COPD. Subjects with ACO had worse lung function and more symptoms than subjects with asthma or COPD only.

- Objectives Combinations of inhaled corticosteroids (ICSs) and long-acting 2-agonists (LABAs) are recommended for patients with moderate and severe chronic obstructive pulmonary disease (COPD). However, it is not known whether different fixed combinations are equally effective. The aim of this study was to investigate exacerbation rates in primary care patients with COPD treated with budesonide/formoterol compared with fluticasone/salmeterol. Methods Patients with physician-diagnosed COPD and a record of postdiagnosis treatment with a fixed combination of budesonide/formoterol or fluticasone/salmeterol were included. Data from primary care medical records were linked to those from Swedish national hospital, drug and cause of death registers. Pairwise (1:1) propensity score matching was carried out at the index date (first prescription) by prescribed fixed ICS/LABA combination. Exacerbations were defined as hospitalizations, emergency visits and collection of oral steroids or antibiotics for COPD. Yearly event rates were compared using Poisson regression. Results Matching of 9893 patients (7155 budesonide/formoterol and 2738 fluticasone/salmeterol) yielded two cohorts of 2734 patients, comprising 19170 patient-years. The exacerbation rates were 0.80 and 1.09 per patient-year in the budesonide/formoterol and fluticasone/salmeterol groups, respectively (difference of 26.6%; P<0.0001); yearly rates for COPD-related hospitalizations were 0.15 and 0.21, respectively (difference of 29.1%; P<0.0001). All other healthcare outcomes were also significantly reduced with budesonide/formoterol versus fluticasone/salmeterol. Conclusions Long-term treatment with fixed combination budesonide/formoterol was associated with fewer healthcare utilization-defined exacerbations than fluticasone/salmeterol in patients with moderate and severe COPD.

- Background: The importance of identifying chronic obstructive pulmonary disease (COPD) at an early stage is recognised. Improved and easily accessible identification of individuals at risk of COPD in primary care is needed to select patients for spirometry more accurately. Aims: To explore whether use of a mini-spirometer can predict a diagnosis of COPD in patients at risk of COPD in primary care, and to assess its cost-effectiveness in detecting patients with COPD. Methods: Primary care patients aged 45-85 years with a smoking history of >= 15 pack-years were selected. Data were collected on the Clinical COPD Questionnaire (CCQ), Medical Research Council (MRC) dyspnoea scale and smoking habits. Lung function (forced expiratory volume in 1 and 6 s; FEV1 and FEV6, respectively) was measured by mini-spirometer (copd-6), followed by diagnostic standard spirometry (COPD diagnosis post-bronchodilation ratio of FEV1 to forced vital capacity (FVC) <0.7). Time consumed was recorded. Univariate logistic regression and receiver operating characteristic (ROC) curves were used. Results: A total of 305 patients (57% females) of mean (SD) age 61.2 (8.4) years, mean (SD) total CCQ 1.0 (0.8) and mean (SD) MRC 0.8 (0.8) were recruited from 21 centres. COPD was diagnosed in 77 patients (25.2%) by standard diagnostic spirometry. Using the copd-6 device, mean (SD) FEV1/FEV6 was 68 (8)% in patients with COPD and 78 (10)% in patients without COPD. Sensitivity and specificity at a FEV1/FEV6 cut-off of 73% were 79.2% and 80.3%, respectively. The area under the ROC curve was 0.84. Screening with the copd-6 device significantly predicted COPD. Gender, CCQ, and MRC were not found to predict COPD. Conclusions: Using the copd-6 as a pre-screening device, the rate of COPD diagnoses by standard diagnostic spirometry increased from 25.2% to 79.2%. Although the sensitivity and specificity of the copd-6 could be improved, it might be an important device for pre-screening of COPD in primary care and may reduce the number of unnecessary spirometric tests performed.
