CHW Survey App
CHW Survey App 2.0 is finally here. After three months and thousands of lines of code the app is now ready for deployment.
First a summary
The CHW app is intended to replace the traditional pen and paper collecting of health survey data by community health workers. This will eliminate ambiguity of data, enhance security of personal information and guarantee safety of data. Beyond the obvious benefits of going digital, the CHW survey app is integrated with a web database which in turn can be accessed by a user friendly web interface to visualize and manage data.
Version 1.0
To get a feel of how far we’ve come, here are a few screenshots of version 1.0
The end product
The goal here is to collect health information using the phone for each household member of each house in the village and also record relevant health related data about the houses themselves including gps coordinates that will be used to display the houses on a map. The map will have filters that can be used to isolate households with specific information for example houses without latrines, houses with pregnant women etc. Community health workers are supposed to be able to walk back to the houses they recorded and edit any changes/corrections in the households form their phone. On the web we are supposed to have something like the one below:
The app
Due to the private nature of the personal health information CHW’s have access only to records of households/villages they are assigned. No one else with access to the CHW’s phone should be able to access the data. So the app starts with a login screen
After login the CHW will choose the action they to want to take.
View/Update: - this is for viewing and editing households they have added and already stored on a web database.
Add household: - this action creates a new household in the selected village. It is here that the user will record the members of the houses and the health records. The questions that the user has to answer for each person depend on their age and sex. For example when the CHW enters a female over 12 years old they will see questions pertaining to maternity. For anyone over 16 years old they will be prompted for the phone number of the subject. After all members of the house have been recorded the CHW is prompted for household information. In the meantime, the phone automatically tries to locate the GPS coordinates of the house.
Change village – this action sets a village value without which the View/Update and Add Household buttons remain disabled.
Manage – All the record entered remains on the phone until they are deleted or exported to database. While still on the phone the CHW can view the houses she entered, view members of the house, edit house and members, add members to the house etc.
Backup: - This action backs up all the recorded information on a local storage on the phone in case of anything.
Export: - When the CHW clicks export the data on the phone is sent to an online database and consolidated with the other records sent by other CHWs. This can then be viewed on the map and managed both by the CHW and a system administrator.
The video below is a capture of the app in action. Below is how the record entered is finally seen on the web.
