Comorbidity indices calculated from electronic health records are commonly used in research studies for various reasons, including study inclusion criteria or to adjust for overall health status. However, changes in diagnosis codes and/or billing practices may alter index values and lead to inaccurate inclusions/exclusions or covariate adjustment. While extracting data for two retrospective cohort

Based on estimates from log-linear difference-in-differences models, our results indicate after the CAAA designation for PM2.5 in 2005, PM2.5 levels decreased 1.59 micrograms per cubic meter (95% CI = 1.39, 1.80) and mortality rates among those 65 and older decreased by 0.93% (95% CI = 0.10%, 1.77%) in nonattainment counties, relative to attainment ones. Results are robust to a series of alternate

Latent class models have become a popular means of summarizing survey questionnaires and other large sets of categorical variables. Often these classes are of primary interest to better understand complex patterns in data. Increasingly, these latent classes are reified into predictors of other outcomes of interests, treating the most likely class as the true class to which an individual belongs ev

The Dictionary of Epidemiology defines epidemiology as “the study of the distribution and determinants of health-related states and events.” The definition given by the WHO appends to this the phrase “(including disease).” In both definitions, it is health, not disease, that is the focus. However, in actual practice, epidemiologic research focuses on diseases and on risk factors for disease, rathe

The availability of large datasets from multiple sources [e.g. registries, biobanks, electronic health records (EHRs), claims or billing databases, implantable devices, wearable sensors, and mobile apps], coupled with advances in computing and analytic technologies, have provided new opportunities for conducting innovative health research. Equally, improved digital access to health information has

Perfluoroalkyl substances (PFAS) can act as surfactants and have been suggested to be capable of affecting gut mucosa integrity, a possible factor in the pathogenesis of inflammatory bowel disease (IBD). So far, only PFOA has been shown to have a positive association with ulcerative colitis. The present study aimed to investigate the association of PFAS and clinically diagnosed IBD in the Ronneby

Clinical practice improvements based on quality-register data are influenced by multiple factors. Although there is agreement that information from quality registers is valuable for quality improvement, practical ways of organising register use have been notoriously difficult to realise. The present study sought to investigate the mechanisms that lead various clinicians to use quality registers fo

Our results suggest that genetic predisposition for CAD can predict hospitalization burden and mortality, especially due to cardiovascular causes, independently of traditional risk factors. As the risk conferred by the GRS is partially modifiable, our results may help to reduce societal costs, individual suffering and prolong life. New publication in IJC Heart & Vasculature

Den 24/2 2020 lanseras LU:s system för datahanteringsplaner, DMP Roadmap. Inloggning sker med LUCAT-id och systemet finns på https://dmp.research.lu.se. Planerna lagras på en server inom LU och rekommendationen är att de inte ska göras publika. De ska däremot bevaras och kan eventuellt arkiveras direkt i systemet.
