Importance SARS-CoV-2 infection is associated with persistent, relapsing, or new symptoms other health effects occurring after acute infection, termed postacute sequelae of (PASC), also known as long COVID . Characterizing PASC requires analysis prospectively and uniformly collected data from diverse uninfected infected individuals. Objective To develop a definition using self-reported describe frequencies across cohorts, vaccination status, number infections. Design, Setting, Participants...
The National COVID Cohort Collaborative (N3C) is a centralized, harmonized, high-granularity electronic health record repository that the largest, most representative COVID-19 cohort to date. This multicenter data set can support robust evidence-based development of predictive and diagnostic tools inform clinical care policy.
<h3>Importance</h3> Understanding of SARS-CoV-2 infection in US children has been limited by the lack large, multicenter studies with granular data. <h3>Objective</h3> To examine characteristics, changes over time, outcomes, and severity risk factors within National COVID Cohort Collaborative (N3C). <h3>Design, Setting, Participants</h3> A prospective cohort study encounters end dates before September 24, 2021, was conducted at 56 N3C facilities throughout US. Participants included younger...
The majority of U.S. reports COVID-19 clinical characteristics, disease course, and treatments are from single health systems or focused on one domain. Here we report the creation National COVID Cohort Collaborative (N3C), a centralized, harmonized, high-granularity electronic record repository that is largest, most representative cohort cases controls to date. This multi-center dataset supports robust evidence-based development predictive diagnostic tools informs critical care policy.In...
OBJECTIVE The purpose of the study is to evaluate relationship between HbA1c and severity coronavirus disease 2019 (COVID-19) outcomes in patients with type 2 diabetes (T2D) acute COVID-19 infection. RESEARCH DESIGN AND METHODS We conducted a retrospective using observational data from National COVID Cohort Collaborative (N3C), longitudinal, multicenter U.S. cohort Patients were ≥18 years old T2D confirmed infection by laboratory testing or diagnosis code. primary outcome was 30-day...
Abstract Objective Clinical encounter data are heterogeneous and vary greatly from institution to institution. These problems of variance affect interpretability usability clinical for analysis. magnified when multisite electronic health record (EHR) networked together. This article presents a novel, generalizable method resolving heterogeneity analysis by combining related atomic encounters into composite “macrovisits.” Materials Methods Encounters were composed 75 partner sites harmonized...
Abstract Objective The goals of this study were to harmonize data from electronic health records (EHRs) into common units, and impute units that missing. Materials Methods National COVID Cohort Collaborative (N3C) table laboratory measurement data—over 3.1 billion patient over 19 000 unique concepts in the Observational Medical Outcomes Partnership (OMOP) common-data-model format 55 partners. We grouped ontologically similar OMOP together for 52 variables relevant COVID-19 research,...
Abstract Importance SARS-CoV-2 Objective To determine the characteristics, changes over time, outcomes, and severity risk factors of affected children within National COVID Cohort Collaborative (N3C) Design Prospective cohort study patient encounters with end dates before May 27th, 2021. Setting 45 N3C institutions Participants Children <19-years-old at initial testing Main Outcomes Measures Case incidence demographic comorbidity factors, vital sign laboratory trajectories, clinical acute...
OBJECTIVE To evaluate the association of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and severity with longer-term glycemic control weight in people type diabetes (T2D) U.S. RESEARCH DESIGN AND METHODS We conducted a retrospective cohort study using longitudinal electronic health record data patients SARS-CoV-2 from National COVID Cohort Collaborative (N3C). Patients were ≥18 years old an ICD-10 diagnosis T2D at least one HbA1c measurement prior to after index date...

ABSTRACT STUDY QUESTION Do recent changes in European Society of Human Reproduction and Embryology (ESHRE) clinical guidelines result more comprehensive diagnosis women with endometriosis? SUMMARY ANSWER The latest shift results endometriosis but current ESHRE diagnostic criteria do not capture a sizable percentage the disease. WHAT IS KNOWN ALREADY Historically, laparoscopy was gold standard for diagnosing endometriosis, complex gynecological condition marked by heterogeneous set symptoms...
