Support for population-based internal and external epidemiological investigations of clinical health of aggregate patient data for use in identifying health risks from the environment, and/or population in accordance with jurisdictional law.
A care provider, public health expert, or organization may wish to analyze data from cohorts,(i.e., subpopulations defined by certain characteristics or conditions). For example, cohorts can be described in terms of demographics; education and social status; health status, diseases, or outcomes; industry and occupation; or injuries. Population health analysts, such as experts in public health departments, may compile individual, and/or population information reported or otherwise gathered from multiple EHRs within the jurisdictional area for surveillance and research. Populations of one or none also can be informative. By analyzing specified data for a cohort, public health experts and care providers can monitor disease prevalence and health-related trends; evaluate behavioral, socio-economical, occupational, and other impacts on health; and identify potential outbreaks and associated risk factors. Examples include:
Case and population information are subject to public health reporting. Care organizations may require population health reports, for example, to measure quality of care based on health improvements for populations under the care of their providers. Statistical analyses are a key component to analyzing population health data, such as epidemiological investigations to identify relationships between risks (such as exposures or behaviors) and health conditions. Individual clinicians or healthcare organizations may employ limited capabilities in EHR systems to analyze population health data. The EHR system also should be capable of interacting with, and leveraging, the capabilities of specialized external analytical systems.
The investigator may hide or mask certain aspects of epidemiological investigation information, as necessary according to scope of practice, policy, and/or law. The investigator may desire to tag or remove patients from the cohort who have relocated or died.
