Capturing Patient allergies

The ability to capture patient allergies has been introduced recently in Bahmni. This allows the providers to search for an allergen and capture the reactions and also mark its severity. The following workflow demonstrates how allergies can be captured for the patients.
The new allergies display control has an “add” button, which is enabled only when the patient has an active visit
Once the add button is clicked, the side panel opens which allows the providers to search for allergens. The provider can either type the name of the allergen (example “Milk products”) or type in the category “food” which displays all the allergens under food. The categories and allergens are obtained from CIEL and can be configured by implementation requirements.
Once the allergen is selected, the user can capture multiple reactions associated with the allergen. The user can either search for the reactions or select using the checkboxes
Finally, the provider can select the severity and add additional comments and save the observation.
This is reflected on the patient dashboard as seen under
Technical Details:
The Allergies display control is developed in React framework and is rendered using the Micro frontend Architecture. The code related to Allergies Display control resides in Bahmni Apps → Micro-frontends → next-ui folder. All the development related to Add Allergies side panel is developed using the components provided by Carbon Design System.
All the data captured for Allergies is in accordance with FHIR resources. AllergyIntolerance - FHIR v6.0.0-ballot2
The list of Allergens, Reactions & Severities are stored as Concepts Sets. The application supports 4 kinds of allergens and are to be added as concepts Sets.
Medication allergens
Environmental Allergens
Food Allergens
Other Allergens.
Note: Once an allergen & corresponding Reactions is captured for a patient. We cannot add the same allergen for the same patient.
Eg: For a patient, If we capture the data as Allergen: Bee, Reaction: Anaemia, Cough, Severity: Moderate. We cannot perform an edit or capture another set of reactions for the Allergen: Bee for that patient.
Reaction Severities:
The FHIR Standards support only 3 types of Severities:
Mild
Moderate
Severe
Valueset-reaction-event-severity - FHIR v5.0.0
Configurations to be added:
In clinical app.json file we need to add config map which provides the uuids for the concept sets for all the allergen kinds , Reactions & Severities.
