Allergies
Source Object: Allergies
Overview and Usage: The "Allergies" source object in athena EHR is instrumental in managing and documenting patient allergies. It provides a structured approach to record, categorize, and track allergies, ensuring patient safety and healthcare efficiency.
- Allergy Documentation: "Allergies" serves as the primary repository for recording patient allergies. It captures critical information related to allergens, reactions, criticality, and other relevant details.
- Allergen Identification: The source object contains fields like "allergenid" and "allergenname" for specifying the allergen causing the patient's allergic reactions. This is essential for accurate allergy identification and management.
- Criticality Assessment: "criticality" indicates the severity of the allergy, helping healthcare providers understand the potential impact on the patient's health.
- Onset and Deactivation: Fields such as "onsetdate," "deactivatedate," and "reactivatedate" provide insights into when the allergy started, when it was deactivated, and when it was reactivated, aiding in tracking the allergy's history.
- Reactions and Severity: "reactions" and "reactions.severity" fields describe the patient's allergic reactions and their severity. This information is crucial for treatment and avoidance strategies.
- SNOMED Codes: "reactions.snomedcode" and "reactions.severitysnomedcode" employ standardized SNOMED codes for reactions and their severity, ensuring consistent data exchange and interpretation.
- RxNorm Codes: "rxnormcode" and "rxnormdescription" fields associate the allergy with relevant RxNorm codes and descriptions, enhancing interoperability with medication data.
- Categorization: "categories" allows for categorizing allergies based on specific criteria, streamlining the organization of allergy data.
- Patient-Facing Calls: "PATIENTFACINGCALL" indicates whether the allergy requires patient notification or a follow-up call.
- Third-Party Involvement: "THIRDPARTYUSERNAME" records third-party user involvement in allergy management or notification.
- NKDA (No Known Drug Allergies): "nkda" specifies if the patient has no known drug allergies, a critical piece of information for safe medical treatment.
- Section Notes: "sectionnote" can contain additional notes and context related to the allergy, offering healthcare providers a more comprehensive understanding.
- Reaction Name: "reactions.reactionname" allows for specifying the names of allergic reactions, aiding in precise documentation.
The "Allergies" source object ensures accurate and comprehensive documentation of patient allergies, improving patient safety and healthcare decision-making. It facilitates the systematic recording of allergy-related data, using standardized codes for interoperability and enhancing the overall quality of healthcare services. Developers can leverage this source object to build features and applications that support the management of patient allergies within athena EHR.
