Agreement was assessed using % agreement, kappa, and weighted kappa. The capacity to predict 30-day and 1-year mortality was assessed using logistic regression, model discrimination with the c-statistic, and calibration with a goodness-of-fit statistic.Results: The CCI was complete (n=959) when calculated from chart than from administrative data (n=839). Agreement was good, with a weighted kappa of 0.667 (95% confidence interval: 0.596–0.714). The c-statistics for categorized CCI scores from charts and administrative data were similar in the model that included age, sex, and type of admission: 0.755 and 0.743 for 30-day mortality, respectively, and 0.783 and 0.775, respectively, for 1-year mortality. Goodness-of-fit statistics supported the model fit.Conclusion: The CCI scores from chart review and administrative data showed good agreement and predicted 30-day and 1-year mortality in ICU patients. CCI combined with age, sex, and type of admission predicts mortality almost as well as the physiology-based SAPS II.

Abstract

Ying Wang,1–3 Knut Stavem,1–3 Fredrik A Dahl,1 Sjur Humerfelt,4 Torbjørn Haugen1,5 1Health Services Research Unit, 2Department of Pulmonary Medicine, Akershus University Hospital, 3Faculty of Medicine, University of Oslo, Lørenskog, Norway; 4Department of Pulmonary Medicine, Oslo University Hospital, Aker, 5Clinic for Allergy and Airway Diseases, Oslo, Norway Background: Early identification of patients with a prolonged stay due to acute exacerbation of chronic obstructive pulmonary disease (COPD) may reduce risk of adverse event and treatment costs. This study aimed to identify predictors of prolonged stay after acute exacerbation of COPD based on variables on admission; the study also looked to establish a prediction model for length of stay (LOS). Methods: We extracted demographic and clinical data from the medical records of 599 patients discharged after an acute exacerbation of COPD between March 2006 and December 2008 at Oslo University Hospital, Aker. We used logistic regression analyses to assess predictors of a length of stay above the 75th percentile and assessed the area under the receiving operating characteristic curve to evaluate the model's performance. Results: We included 590 patients (54% women) aged 73.2±10.8 years (mean ± standard deviation) in the analyses. Median LOS was 6.0 days (interquartile range [IQR] 3.5–11.0). In multivariate analysis, admission between Thursday and Saturday (odds ratio [OR] 2.24 [95% CI 1.60–3.51], P11 days. The statistical model had an area under the receiver operating characteristic curve of 0.73. Conclusion: Admission between Thursday and Saturday, heart failure, diabetes, stroke, high arterial PCO2, and low serum albumin level were associated with a prolonged LOS. These findings may help physicians to identify patients that will need a prolonged LOS in the early stages of admission. However, the predictive model exhibited suboptimal performance and hence is not ready for clinical use. Keywords: exacerbation, COPD, predictors, length of stay, predicting model

Abstract

Objective Finasteride 5 mg is a drug used to treat prostate hyperplasia. Little is known about its pattern of usage. This cross-national analysis of individual-level data from Denmark, Finland, Norway and Sweden was undertaken to appraise its usage and describe cross-national differences. Materials and methods Individual-level data from nationwide prescription registers in Denmark (1995-2009), Finland (1997-2010), Norway (2004-2009) and Sweden (July 2005-2011) were used to examine cross-national finasteride utilization patterns in the adult male population (≥15 years). The study presents period prevalences, incidence rates, waiting time distributions and Lorenz curves. Results During the study period, 295,620 men had at least one prescription redemption of finasteride 5 mg, and there were approximately 3 million dispensing events of finasteride prescriptions in the four Nordic countries. Different patterns of finasteride use were observed among the four Nordic countries. The period prevalence was markedly higher in Finland and Sweden than in Denmark and Norway. In 2009, period prevalences were 18.2/1000 males in Finland and 12.0/1000 males in Sweden compared to 6.7/1000 males in Norway and 4.9/1000 males in Denmark. Incidence rates of finasteride use for Finland, Norway and Sweden were about three times that for Denmark in 2008-2009. Long-term use of finasteride was found in all four Nordic countries with a high ratio between prevalent and incident users. Conclusion Despite resemblances regarding political systems and healthcare services in the Nordic countries, differences in finasteride utilization were found across Denmark, Finland, Norway and Sweden.

Abstract

To assess the agreement of a self-completed diary to monitor respiratory symptoms in children aged 6-12 years with parental symptom reports and fluctuations in lung function.We created a text- and symbol-based questionnaire for daily completion by children at school. Using a screening questionnaire completed by the parents, we selected 101 children with lower respiratory symptoms in the last year or doctor-diagnosed asthma to complete the diary. We assessed the agreement with a parent-completed daily symptom diary and measurements of peak expiratory flow (PEF) over 5 weeks, estimating % agreement and the kappa statistic (kappa) for pairwise comparisons.Simple agreement between PEF variability, parent-reported and child-reported symptoms was moderate to high. Using kappa, agreement between children's and parents' reports of respiratory symptoms was only fair to moderate, and agreement with lung function measurements was poor for both parent- and child-reported symptoms.Agreement between children's and parents' reports on day-to-day respiratory symptoms was fair to moderate. The children's symptom diary agreed poorly with lung function measurements, but was neither worse nor better than the parent-completed diary.
