Artifacts Summary

Contents:

This page provides a list of the FHIR artifacts defined as part of this implementation guide.

Structures: Resource Profiles

These define constraints on FHIR resources for systems conforming to this implementation guide

MMEMedicationRequest

Defines the minimum expectations for a MedicationRequest that can be used to successfully calculate Morphine Milligram Equivalent (MME)/day according to the CDC Opioid Prescribing guideline

Terminology: Code Systems

These define new code systems used by systems conforming to this implementation guide

CDC MME Clinical Conversion Factors

This Code System Supplement defines clinical conversion factors for calculating Morphine Milligram Equivalence (MME), as described in the CDC Opioid Prescribing Guideline. The supplement defines conversions factors for ingredients in one of 3 ways: 1, as a direct conversion factor for the ingredient, 2, as a dose-form-specific conversion factor for the ingredient, and 3, as a dose-quantity-ranged conversion factor for the ingredient. See the descriptions for each property for information on how the values are represented for the different conversion factors. For a given ingredient, only one of ‘dose-form’ or ‘dose-range’ will be present, with or without an ingredient-specific conversion factor. The properties together will enable a unique conversion factor to be determined if the input is within the expected range. If the input is outside the expected range, and there is no ingredient-specific conversion-factor specified, implementations should indicate a conversion factor could not be determined from the supplied information. All conversion factors supplied in this supplement are in ‘mg/d’.
CDC MME Usage Context Codes

This Code System defines usage context codes used to configure the MME Conversion Factors Code System Supplement. If there is a single CodeSystem supplement to the RxNorm code system with a usage context of task and a code of ‘mme-calculation’, it will be used as the conversion factors for the calculator. See the Conversion Factors documentation for a description of the Code System supplements that can carry this configuration.
Example CDC MME Clinical Conversion Factors

Example Code System to support Testing (Copy of ClinicalConversion Factors). This Code System Supplement is a copy of the CDC Clinical Conversion Factors code system supplement to support testing. See the original CDC Clinical Conversion Factors code system supplement for documentation of the code system supplement properties.
