Configuring Tasks

Configuring CHT tasks

Tasks guide health workers through their days and weeks.

This tutorial will take you through how to configure tasks for CHT applications, including:

Authoring tasks
Compiling tasks into app settings and uploading

You will be configuring a task that allows Community Health Workers to conduct a health assessment follow up for children under the age of 5 that have a cough lasting more than 3 days, within 24 hours.

Brief Overview of Key Concepts

Tasks gives a UI overview of tasks.

Anatomy of a Task takes you through the anatomy of a task

Task schema details a set of properties for tasks.

Utils define a set of utility functions in the Core Framework can make common tasks much easier.

Nools extras where helper variables and functions for Tasks and Targets are defined.

Required Resources

You should have a functioning CHT instance with cht-conf installed locally, completed a project folder setup, and an assessment form.

Implementation Steps

It is good practice to set up a reference document for the tasks similar to the one below. Other formats may also be used.

Source	UI Label	Condition	Due Date	Resolved	Window period
Assessment form	Assessment follow up	cough_duration > 3	reported + 1 days	When assessment follow up or another assessment report is submitted	7 days

Create the task as per the detail above.

1. Define the task

{
    name: 'cough-gt-3-days-follow-up',
    icon: 'icon-followup-general',
    title: 'task.cough_gt_3_days.follow_up',
    appliesTo: 'reports',
    appliesToType: ['assessment'],
    appliesIf: function(contact, report) {
      return report && report.fields.group_assessment && parseInt(report.fields.group_assessment.cough_duration) > 3;
    },
    actions: [
      {
        type: 'report',
        form: 'assessment_follow_up'
      }
    ],
    events: [
      {
        id: 'cough-gt-3-days-follow-up',
        days: 0,
        start: 2,
        end: 7
      }
    ],
    resolvedIf: function(contact, report, event, dueDate) {
      const startTime = Math.max(addDays(dueDate, -event.start).getTime(), report.reported_date);
      const endTime = addDays(dueDate, event.end + 1).getTime();
      return isFormArraySubmittedInWindow(
        contact.reports, ['assessment_follow_up'], startTime, endTime
      );
    }
}

2. Create an `assessment_follow_up` form as specified below referenced by the task you created. Refer to the app-forms tutorial.

Data fields

type	name	label	required	relevant
begin group	group_assessment	Assessment
select_one yes_no	visited_hf	Did ${patient_name} go to a health facility for treatment?	yes
select_one progress_since_last_visit	progress	How is ${patient_name}‘s condition since the last visit?	yes	${visited_hf} = ‘yes’
end group

Choices

list_name	name	label
yes_no	yes	Yes
yes_no	no	No
progress_since_last_visit	improved	Improved
progress_since_last_visit	same	Stayed same
progress_since_last_visit	worse	Worsened

Settings

form_title	form_id	version	style	path	instance_name	default_language
Follow up	assessment_follow_up	1	pages	data		en

Sub-folder

forms/app

Build

To build your tasks into your app, you must compile them into app-settings, then upload them to your instance.

cht --url=https://<username>:<password>@localhost --accept-self-signed-certs compile-app-settings backup-app-settings upload-app-settings

Remember to convert and upload your assessment_follow_up form

cht --url=https://<username>:<password>@localhost --accept-self-signed-certs convert-app-forms upload-app-forms -- assessment_follow_up
