However, complex multi-level confounding related to patient-level and surgeon or hospital covariates hampers observational studies of risks and benefits. We conducted two simulation studies to compare the performance of Causal Forests (CF) vs Inverse Probability of Treatment Weighting (IPTW) to…
Open article record in new tab ↗ObjectivesWe aimed to assess the risk of autoimmune- and inflammatory post-acute COVID-19 conditions. DesignDescriptive network cohort study. SettingElectronic health records from UK and Dutch primary care, Norwegian linked health registry, hospital records of specialist centres in Spain, France, and Korea, and healthcare claims from Estonia and the US. ParticipantsWe followed individuals between September 2020 an…
BackgroundSeveral definitions exist for multimorbidity, frailty or polypharmacy, but no formal definition exists for "complex health needs". We aimed to identify and characterise older people with complex health needs based on healthcare resource use (unplanned hospitalisations or polypharmacy) or frailty. MethodsIn this cohort study, data was extracted from UK primary care records (CPRD GOLD), with linked Hospita…
Open article record in new tab ↗ObjectivesTo explore clustering of comorbidities among patients with a new diagnosis of osteoarthritis (OA) and estimate the 10-year mortality risk for each identified cluster. MethodsThis is a population-based cohort study of individuals with first incident diagnosis of OA of the hip, knee, ankle/foot, wrist/hand, or unspecified site between 2006 and 2020, using SIDIAP (a primary care database representative from…
Open article record in new tab ↗BackgroundRoutinely collected healthcare data such as administrative claims and electronic health records (EHR) can complement clinical trials and spontaneous reports when ensuring the safety of vaccines, but uncertainty remains about what epidemiological design to use. MethodsUsing 3 claims and 1 EHR database, we evaluate several variants of the case-control, comparative cohort, historical comparator, and self-co…
Open article record in new tab ↗Using real-world data and past vaccination data, we conducted a large-scale experiment to quantify bias, precision and timeliness of different study designs to estimate historical background (expected) compared to post-vaccination (observed) rates of safety events for several vaccines. We used negative (not causally related) and positive control outcomes. The latter were synthetically generated true safety signals…
Open article record in new tab ↗PurposeWe aimed to describe the demographics, cancer subtypes, comorbidities and outcomes of patients with a history of cancer with COVID-19 from March to June 2020. Secondly, we compared patients hospitalized with COVID-19 to patients diagnosed with COVID-19 and patients hospitalized with influenza. MethodsWe conducted a cohort study using eight routinely-collected healthcare databases from Spain and the US, stan…
Open article record in new tab ↗BackgroundIn this study we phenotyped individuals hospitalised with coronavirus disease 2019 (COVID-19) in depth, summarising entire medical histories, including medications, as captured in routinely collected data drawn from databases across three continents. We then compared individuals hospitalised with COVID-19 to those previously hospitalised with influenza. MethodsWe report demographics, previously recorded…
