Objective To investigate the occurrence of pneumonia and pneumonia related events in patients with chronic obstructive pulmonary disease (COPD) treated with two different fixed combinations of inhaled corticosteroid/long acting β2 agonist. Design Observational retrospective pairwise cohort study matched (1:1) for propensity score. Setting Primary care medical records data linked to Swedish hospital, drug, and cause of death registry data for years 1999-2009. Participants Patients with COPD diagnosed by a physician and prescriptions of either budesonide/formoterol or fluticasone/salmeterol. Main outcome measures Yearly pneumonia event rates, admission to hospital related to pneumonia, and mortality. Results 9893 patients were eligible for matching (2738 in the fluticasone/salmeterol group; 7155 in the budesonide/formoterol group), yielding two matched cohorts of 2734 patients each. In these patients, 2115 (39%) had at least one recorded episode of pneumonia during the study period, with 2746 episodes recorded during 19 170 patient years of follow up. Compared with budesonide/formoterol, rate of pneumonia and admission to hospital were higher in patients treated with fluticasone/salmeterol: rate ratio 1.73 (95% confidence interval 1.57 to 1.90; P<0.001) and 1.74 (1.56 to 1.94; P<0.001), respectively. The pneumonia event rate per 100 patient years for fluticasone/salmeterol versus budesonide/formoterol was 11.0 (10.4 to 11.8) versus 6.4 (6.0 to 6.9) and the rate of admission to hospital was 7.4 (6.9 to 8.0) versus 4.3 (3.9 to 4.6). The mean duration of admissions related to pneumonia was similar for both groups, but mortality related to pneumonia was higher in the fluticasone/salmeterol group (97 deaths) than in the budesonide/formoterol group (52 deaths) (hazard ratio 1.76, 1.22 to 2.53; P=0.003). All cause mortality did not differ between the treatments (1.08, 0.93 to 1.14; P=0.59). Conclusions There is an intra-class difference between fixed combinations of inhaled corticosteroid/long acting β2 agonist with regard to the risk of pneumonia and pneumonia related events in the treatment of patients with COPD.

Combinations of inhaled corticosteroids (ICSs) and long‐acting β2‐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.

Background: There is a lack of studies of the size of burden associated with informal care giving in psychosis. Aims: To evaluate the objective and subjective burden of informal care giving to patients with psychoses, and to compare a diary and recall method for assessments of objective burden. Method: Patients and their informal caregivers were recruited from nine Swedish psychiatric outpatient centres. Subjective burden was assessed at inclusion using the CarerQoL and COPE index scales. The objective burden (time and money spent) was assessed by the caregivers daily using diaries over four weeks and by recall at the end of weeks 1 and 2. Results: One-hundred and seven patients (53% females; mean age 43 ± 11) and 118 informal caregivers (67%; 58 ± 15 years) were recruited. Informal caregivers spent 22.5 hours/week and about 14% of their gross income on care-related activities. The time spent was underestimated by two to 20 hours when assessed by recall than by daily diary records. The most prominent aspects of the subjective burden were mental problems. Conclusion: Despite a substantial amount of time and money spent on care giving, the informal caregivers perceived the mental aspects of burden as the most troublesome. The informal caregiver burden is considerable and should be taken into account when evaluating effects of health care provided to patients with psychoses.

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 prescreening of COPD in primary care and may reduce the number of unnecessary spirometric tests performed.

OBJECTIVES To map out-patients with Chronic Obstructive Pulmonary Disease (COPD) with special reference to patients suffering from acute exacerbations, and to describe COPD health care structure and process in Swedish clinical practice in a real life setting. DESIGN Retrospective, non-interventional, epidemiological survey. SETTING 141 hospital based out patient clinics (OPC, n=30) and primary health care clinics (PC, n=111) were included in the structure evaluation. SUBJECTS 1004 COPD diagnosed patients from 100 of the centres (OPC, n=26) participated in the process evaluation. METHODS All Swedish OPC (n=40) and a random sample of 180 PC were asked to answer a questionnaire regarding COPD care. In addition, data from 10 randomly selected patients with a documented COPD disease were analysed from the centres. RESULTS Spirometers were available at all OPCs and at 99% of the PCs. Spirometry had been performed in 52% of PC-patients and in 89% of OPC-patients during the last 2 years prior to the study. More severe patients, as judged by investigator and lung function data, were treated at OPCs than at PCs. Physiotherapists, occupational therapists and dieticians were available at >80% of centres. Exacerbation rate was higher at PCs without a specialized nurse, 2.2/year versus 0.9/year at centres with a specialized nurse. CONCLUSIONS Special attention to COPD, marked by a specialised nurse in primary care improves the quality, as assessed by a lower number of exacerbations. The structure of COPD care in Sweden for diagnosed individuals seems satisfactory, but could be improved mainly through higher availability and educational activities.

Background In mild asthma exercise-induced bronchoconstriction (EIB) is usually treated with inhaled short-acting β2 agonists (SABAs) on demand. Objective The hypothesis was that a combination of budesonide and formoterol on demand diminishes EIB equally to regular inhalation of budesonide and is more effective than terbutaline inhaled on demand. Methods Sixty-six patients with asthma (>12 years of age) with verified EIB were randomised to terbutaline (0.5 mg) on demand, regular budesonide (400 μg) and terbutaline (0.5 mg) on demand, or a combination of budesonide (200 μg)  + formoterol (6 μg) on demand in a 6-week, double-blind, parallel-group study (ClinicalTrials.gov identifier: NCT00989833). The patients were instructed to perform three to four working sessions per week. The main outcome was EIB 24 h after the last dosing of study medication. Results After 6 weeks of treatment with regular budesonide or budesonide+formoterol on demand the maximum post-exercise forced expiratory volume in 1 s fall, 24 h after the last medication, was 6.6% (mean; 95% CI −10.3 to −3.0) and 5.4% (−8.9 to −1.8) smaller, respectively. This effect was superior to inhalation of terbutaline on demand (+1.5%; −2.1 to +5.1). The total budesonide dose was approximately 2.5 times lower in the budesonide+formoterol group than in the regular budesonide group. The need for extra medication was similar in the three groups. Conclusions The combination of budesonide and formoterol on demand improves asthma control by reducing EIB in the same order of magnitude as regular budesonide treatment despite a substantially lower total steroid dose. Both these treatments were superior to terbutaline on demand, which did not alter the bronchial response to exercise. The results question the recommendation of prescribing SABAs as the only treatment for EIB in mild asthma.

Lars Eriksson; Teresa Hallerbäck; Leif Jörgensen; Andreas Carlborg

Quetiapine fumarate, a first-line treatment for schizophrenia, exists in two formulations: extended release (XR) and immediate release (IR). This naturalistic, noninterventional study evaluated use of quetiapine XR/IR among in-patients with schizophrenia [ClinicalTrials.gov identifier: NCT01214135]. Data were collected from medical records. Categorical and numerical outcomes were compared using χ2 and t tests. Of 178 enrolled patients, 66% and 34% used quetiapine XR and IR respectively. Based on mean daily dose, XR was used as antipsychotic medication in 64% of patients compared with 40% of patients on IR (dose ≥ 400 mg/day; p = 0.002) and in higher doses than IR (494 versus 345 mg/day; p = 0.001; calculated averages). Schizophrenia was more commonly reported as reason for use of XR than IR (20% versus 0%; p = 0.0003). Patients with comorbid substance abuse or somatic disease were more likely to receive XR (p = 0.003; p = 0.03). Treatment cessation due to nonadherence was less common in patients on XR (3.4% versus 12%; p = 0.03). Polypharmacy was seen in 98% of patients. Quetiapine XR/IR usage varies in hospitalized patients with schizophrenia. XR is more often used in antipsychotic dosage; IR is more commonly used at lower doses as add-on therapy. Both quetiapine XR and IR have their place in clinical practice and provide treatment choice in schizophrenia.

Background We assessed direct and indirect costs associated with COPD in Sweden and examined how these costs vary across time, age, and disease stage in a cohort of patients with COPD and matched controls in a real-world, primary care (PC) setting. Patients and methods Data from electronic medical records linked to the mandatory national health registers were collected for COPD patients and a matched reference population in 52 PC centers from 2000 to 2014. Direct health care costs (drug, outpatient or inpatient, PC, both COPD related and not COPD related) and indirect health care costs (loss of income, absenteeism, loss of productivity) were assessed. Results A total of 17,479 patients with COPD and 84,514 reference controls were analyzed. During 2013, direct costs were considerably higher among the COPD patient population (€13,179) versus the reference population (€2,716), largely due to hospital nights unrelated to COPD. Direct costs increased with increasing disease severity and increasing age and were driven by higher respiratory drug costs and non-COPD-related hospital nights. Indirect costs (~€28,000 per patient) were the largest economic burden in COPD patients of working age during 2013. Conclusion As non-COPD-related hospital nights represent the largest direct cost, management of comorbidities in COPD would offer clinical benefits and relieve the financial burden of disease.

This study aimed to generate real-world evidence to assess the burden of comorbidities in COPD patients, to effectively manage these patients and optimize the associated healthcare resource allocation. ARCTIC is a large, real-world, retrospective cohort study conducted in Swedish COPD patients using electronic medical record data collected between 2000 and 2014. These patients were studied for prevalence of various comorbidities and for association of these comorbidities with exacerbations, mortality, and healthcare costs compared with an age-, sex-, and comorbidities-matched non-COPD reference population. A total of 17,479 patients with COPD were compared with 84,514 non-COPD reference population. A significantly higher prevalence of various comorbidities was observed in COPD patients 2 years post-diagnosis vs. reference population, with the highest percentage increase observed for cardiovascular diseases (81.8% vs. 30.7%). Among the selected comorbidities, lung cancer was relatively more prevalent in COPD patients vs. reference population (relative risk, RR = 5.97, p < 0.0001). Ischemic heart disease, hypertension, depression, anxiety, sleep disorders, osteoporosis, osteoarthritis, and asthma caused increased mortality rates in COPD patients. Comorbidities that were observed to be significantly associated with increased number of severe exacerbations in COPD patients included heart failure, ischemic heart disease, depression/anxiety, sleep disorders, osteoporosis, lung cancer, and stroke. The cumulative healthcare costs associated with comorbidities over 2 years after the index date were observed to be significantly higher in COPD patients (€27,692) vs. reference population (€5141) (p < 0.0001). The data support the need for patient-centered treatment strategies and targeted healthcare resource allocation to reduce the humanistic and economic burden associated with COPD comorbidities.Chronic lung disease: Tailoring treatment to encompass co-existing conditionsCo-existing conditions should be taken into consideration when treating patients with chronic lung disease to ensure coherent and cost-effective disease management. In a large-scale study of the Swedish population, Björn Ställberg at Uppsala University and co-workers analyzed electronic medical records spanning fourteen years for 17,479 patients with chronic obstructive pulmonary disease (COPD) and compared their health status with 84,514 age-, sex- and comorbidity-matched non-COPD members of the population. Patients with COPD were significantly more likely to suffer from co-morbidities two years after initial diagnosis than their non-COPD counterparts, with cardiovascular diseases being the most common comorbidities. Lung cancer, hypertension, depression and sleep disorders were among other comorbidities more prevalent in the COPD population. These data support the need for fully integrated, targeted healthcare to reduce mortality and the economic burden associated with COPD.
