The key benefits of a scalable, automated data capture tool like GRHANITE™ cannot be fully realised in settings with under-developed electronic health infrastructure. While this approach remains promising for creating and maintaining a registry that monitors the quality of CR provided to patients, further investment is required in the digital platforms underpinning this approach. New publication i
Bias and confounding can distort findings from observational studies; adjustment or correction for these sources of error rarely dramatically change the results. Immortal time bias, which is included in the follow-up period during which the study outcome by design cannot occur, is a potential source of bias in longitudinal studies. Researchers often assume that immortal time bias has, if anything,

The process of conducting and disseminating findings of epidemiologic investigations is not standardized. To address this, recommended guidelines, as opposed to mandated rules, were established over 4 decades ago that have become widely endorsed among the biomedical journals, including Epidemiology. One requirement in particular stipulates that the “[m]ethods section should aim to be sufficiently
Standardization by a disease risk score (DRS) may be preferable to weighting on the exposure propensity score if the exposure is difficult to model, relatively novel (i.e., newly emerging or rapidly-evolving), or extremely rare. For exposures with more than two levels, methods are lacking for a DRS-based approach. We present an approach to estimate trends in standardized risk ratios (RRs) based on

The prevalence of CWP remained high over time, but with individual transitions between the pain groups. The development and persistence of CWP were predicted by more pain and worse health, with the addition of female gender and higher age for persistent CWP. Special attention and treatment alternatives for patients with SpA and concomitant CWP are essential in the clinic. New publication in Scandi
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

A powerful neutron source, the European Spallation Source (ESS), is currently under construction in Lund, Sweden (~90 000 inhabitants). Levels of tritium (3H) in urine were estimated in members of the public in Lund and employees at the ESS using liquid scintillation counting, to obtain baseline levels before the start of operation of the ESS.
