Patient Summary Widget Documentation

Featured add: 2.6

This page provides documentation of widgets that can be added to the patient dashboard. To add or modify go to System administration → Manage apps.

If you want to override the behavior of existing one, make sure to use the exact appId of the existing one in all places ( app ID input and json config)

If you want to create a new one based on one of the following examples, make sure you use a different appID in all places

Section Configuration Parameters

The following parameters are required for each section

key	required	description
title	required	The title of the section
provider	optional	A valid moduleId
fragmentId	optional	A valid fragment
icon	optional	The icon displayed for the heading
order	optional	How does this work elsewhere
extensionId	required	The extension where the widget is displayed (How does one configure the section to appear in multiple extension points)

Latest Obs For Concept List

Shows a list of concepts and the latest observations for each one.

Configuration Parameters

key	required	default	values	description
concepts	required		Comma delimited list of Concept numeric id, uuid, or mapping	* Provides the concepts whose most recent obs or group observations are returned are returned. * If the concept has no value it is returned with no value * Text showing how recent the obs is, today, yesterday, n days/months/years ago in smaller italic text whose title is the actual obs date
conceptNameType	optional		FSN shortName preferred	Specifes the preferred format for displaying both the concept and any value-coded concepts. The values correspond to "FULLY_SPECIFIED", "SHORT", and locale_preferred = true, respectively.
maxAge	optional		Numeric integer with a suffix for example: 1d – 1 day 2w – 2 weeks *4m – 4 months from the current date	The maximum age of most recent obs for each of the items in the concept list
obsGroupLabels	optional	none	FSN shortName none	May be used when obs grouping concept uuid(s) are used in the concept key. Specifies the format in which to display obs group member prefixes, FSN, shortName, none. The prefixes to display refer to either Fully Specified Name, Short Name, of the underlying member concept or No prefix respectively.
nLatestObs	optional	1	Numeric integer	Specifies the number of latest non voided observations for a/each concept specified in the concepts key.

Note that large lists of concepts or large values of nLatestObs may impact performance.

Example of dropdown box to navigate to program-specific dashboard to enroll a patient in a program:

Program Status

Shows the specifies of the current patient program enrollment: date enrolled, enrollment location, date completed, and outcome. Allows editing of these four data points, and the deletion of the patient program (assuming the user has the appropriate privilege). If the patient is not currently enrolled in the program, provides the ability to enroll in the program.

An updated version of this widget (likely to be released in Coreapps 1.16.0) provided the ability to set and edit workflow state transitions.

This widget is also used by the Program History widget to allow viewing and editing of completed programs.

Configuration Parameters

key	required	default	description	minimum version
program	required		Program UUID (ie. uuid of a program in OpenMRS Program table)
dateFormat	optional	yyyy-MM-dd	Date format to use when displaying dates
locationTag	optional	null	UUID of a location tag. If specified, the options in the "program enrollment location" drop-down will be limited to locations with tag.
markPatientDeadOutcome	optional	null	UUID of a concept. If that concept is selected as the "Program Outcome", user will be redirected to "Mark Patient Deceased" page (assuming the user has the "Task: coreapps.markPatientDead" privilege). For example, if you have an outcome of "Patient Died" this allows you to config the widget to redirect to the "Mark Patient Deceased" page if that outcome is selected.	since Core Apps 1.31.0
dashboard	optional	null	ID of a patient dashboard. Used so that the widget can know the context it is rendered in. Currently, this is used in conjunction with the "markPatientDead" functionality: this dashboard id is passed on to the Mark Patient Dead controller so it can properly generate a return URL to the appropriate dashboard.	since Core Apps 1.31.0

Privileges

Privilege	Description
Task: enrollInProgram	Whether the user has the ability to enroll a patient in a program
Task: editPatientProgram	Whether the user has the ability to edit an existing patient program

Bahmni Appointments Widget (Capability).

This widget reports on Bahmni Appointments module. It is disabled by default because the Bahmni Appointments module is not part of the Reference Application.

To have this widget show up on patientDashboard when running Bahmni Appointments module, the implementer will have to add the following configuration in a json file named as <name>_app.json under /omod/src/main/resources/app/ :

Bahmni Appointments widget app configuration example

{
  "id": "coreapps.Appointments",
  "instanceOf": "coreapps.template.dashboardWidget",

"instanceOf" : "coreapps.template.dashboardWidget"
config.widget : "bahmniappointments"
extensions.extensionParams.provider: "coreapps",
extensions.extensionParams.fragment: "dashboardwidgets/dashboardWidget",

Note . The param "detailsUrl" : "url" , is the url to redirect the user to the appointments module.

There are a number of additional features that would be helpful on the dashboard: Future enhancements

obsgroup table
- Similar to the obsaccrossencounters but for obsgroups. Should allow for multiple obs within an obsgroup.
- Use case: A list of medications dispensed with encounter date, medication name, and frequency
Graphs
- Graphs with log scale
  - Use case: Viral load scale could vary from non-detectable to 10,000. It would be helpful to graph.
- Multiple variable graphs
  - Use case: Graph 2 or more variables (concepts) on the same graph. Use for weight and height.
- BMI graph
  - Use case: Based on weight and height, graph weight and calculated BMI on a single graph.
