For example, Centers for Medicare & Medicaid Services (CMS) in the U.S. defines four required Supplemental Data Elements (payer, ethnicity, race, and gender), which are variables used to aggregate data into various subgroups. Additional supplemental data elements required for risk adjustment or other purposes of data aggregation can be included in the Supplemental Data Element section.

These include: (1) evaluate the measure based on different age groupings within the population described in the measure (e.g., evaluate the whole [age 14-25] and each sub-stratum [14-19] and [20-25]); (2) evaluate the eMeasure based on either a specific condition, a specific discharge location, or both; (3) evaluate the eMeasure based on different locations within a facility (e.g., evaluate the overall rate for all intensive care units and also some strata include additional findings [specific birth weights for neonatal intensive care units]).

Usage notes.

A sequence of values in the "absolute" time domain. This is the same time domain that all HL7 timestamps use. It is time as measured by the Gregorian calendar

A sequence of values in a "relative" time domain. The time is measured relative to the earliest effective time in the Observation Series containing this sequence.

This Observation Series type contains waveforms of a "representative beat" (a.k.a. "median beat" or "average beat"). The waveform samples are measured in relative time, relative to the beginning of the beat as defined by the Observation Series effective time. The waveforms are not directly acquired from the subject, but rather algorithmically derived from the "rhythm" waveforms.

This Observation type contains ECG "rhythm" waveforms. The waveform samples are measured in absolute time (a.k.a. "subject time" or "effective time"). These waveforms are usually "raw" with some minimal amount of noise reduction and baseline filtering applied.

Observation types for specifying criteria used to assert that a subject is included in a particular population.

Criteria which specify subjects who should be removed from the eMeasure population and denominator before determining if numerator criteria are met. Denominator exclusions are used in proportion and ratio measures to help narrow the denominator.

Criteria which specify the removal of a subject, procedure or unit of measurement from the denominator, only if the numerator criteria are not met. Denominator exceptions allow for adjustment of the calculated score for those providers with higher risk populations. Denominator exceptions are used only in proportion eMeasures. They are not appropriate for ratio or continuous variable eMeasures. Denominator exceptions allow for the exercise of clinical judgment and should be specifically defined where capturing the information in a structured manner fits the clinical workflow. Generic denominator exception reasons used in proportion eMeasures fall into three general categories:

• Medical reasons
• Patient (or subject) reasons
• System reasons

Criteria for specifying the entities to be evaluated by a specific quality measure, based on a shared common set of characteristics (within a specific measurement set to which a given measure belongs). The denominator can be the same as the initial population, or it may be a subset of the initial population to further constrain it for the purpose of the eMeasure. Different measures within an eMeasure set may have different denominators. Continuous Variable eMeasures do not have a denominator, but instead define a measure population.

Criteria for specifying the entities to be evaluated by a specific quality measure, based on a shared common set of characteristics (within a specific measurement set to which a given measure belongs).

Criteria for specifying the patients to be evaluated by a specific quality measure, based on a shared common set of characteristics (within a specific measurement set to which a given measure belongs). Details often include information based upon specific age groups, diagnoses, diagnostic and procedure codes, and enrollment periods.

Defines the observation to be performed for each patient or event in the measure population. Measure observations for each case in the population are aggregated to determine the overall measure score for the population.

Examples:

• the median time from arrival in the Emergency Room to departure
• the median time from decision to admit to a hospital to the actual admission for Emergency Room patients

Criteria for specifying the measure population as a narrative description (e.g., all patients seen in the Emergency Department during the measurement period). This is used only in continuous variable eMeasures.

Criteria for specifying subjects who should be removed from the eMeasure's Initial Population and Measure Population. Measure Population Exclusions are used in Continuous Variable measures to help narrow the Measure Population before determining the value(s) of the continuous variable(s).

Criteria for specifying the processes or outcomes expected for each patient, procedure, or other unit of measurement defined in the denominator for proportion measures, or related to (but not directly derived from) the denominator for ratio measures (e.g., a numerator listing the number of central line blood stream infections and a denominator indicating the days per thousand of central line usage in a specific time period).

Criteria for specifying instances that should not be included in the numerator data. (e.g., if the number of central line blood stream infections per 1000 catheter days were to exclude infections with a specific bacterium, that bacterium would be listed as a numerator exclusion). Numerator Exclusions are used only in ratio eMeasures.

Types of observations that can be made about Preferences.
