Specify, test, and reuse patient cohorts

Patient cohorts

A patient cohort specification is the set of characteristics (inclusion and exclusion criteria) that define which patients are members of a class and which are not.  Amongst other things, a cohort or class of patients can be used to identify who should receive a clinical decision support (CDS) intervention, be included in a quality measurement, be part of a population health registry, or participate in a research study.  Semedy’s Patient Cohort Solution allows an organization to:


  • Create, validate, and share specifications of patient cohorts for use in other knowledge-based applications, such as CDS, electronic quality measurements, population health management systems, and research data repositories

  • Specify patient cohorts with re-usable building blocks (resource queries) to make curation more efficient and to prevent unnecessary variation

  • Investigate, resolve, and even prevent malfunctions caused by population cohorts with faulty or incomplete inclusion or exclusion criteria

  • Implement a coordinated strategy for deploying cohort-related information system functionalities, such as eligibility criteria for CDS, order sets, protocols, pathways, registries, quality measurements, ands research studies




Semedy’s CDS solution includes preconfigured and extensible models, extract/transform/load (ETL) pipelines for input and/or export, convenient authoring templates, configurable views, queries, and reports.  Source content can be loaded from an external source, cloned and modified from existing content, or created de novo.




The demonstration includes how patient cohorts are defined, searched, queried, and validated; and how this solution seamlessly integrates with Semedy’s CDS, eMeasures, metadata management, and synthetic health data solutions.
