3. Name the device and select the device from the 'Class' drop down menu 

4. After selecting the correct device, WTH will automatically set default selections according to what the WTH developers feel is the best selection for that device type.  Be sure to review the defaults and make any necessary changes.  

5. Enter in the device credentials- username and password

• Note: for some devices, WTH will let you 'save' the device even if the username and password are incorrect

6. *NEW* Device Authorization Enrollment Step... is applicable if device set up is a requirement for enrollment. You should select whether or not a participant has to authorize the device, or if they can skip the set up

• Ex: a pedometer study using both Moves and Fitbit 

7. Selection Strategy explanations can be found in How Device Data attaches to Events. However there are some general principles.. 

• First: used for medication adherence devices
• Last:
• Min: used for weight loss studies
• Max: used for physical activity studies 

8. Selection Field determines which field of data WTH should use for a particular device to determine whether a participant completed or was compliant to the encounter

• Ex: Clevercap pill bottle selection field should be IS_TAKEN, which will have the variables 0 and 1 for yes and no to determine encounter completeness and compliance 

9. Attach data and close encounter... indicates when the encounter should close.

• As soon data is available: will immediately close out the encounter once data is received and attaches to the open encounter.
  • Generally used for medication adherence devices
• Wait until the end of the encounter window: encounter will not close until the end of the encounter window.  This is ideal for devices where it may be typical to receive multiple data enteries throughout the course of the encounter.
  • Ex: leave Fitbit encounter window open so that WTH attaches the maximum number of steps walked to the encounter.
  • Ex: leave Nokia Scale encounter window open so that WTH attaches the minimum weight value to the encounter, regardless of how many times the participant steps on the scale.

10. When an already-completed encounter gets new data... determines what to do with new data 

• Attach new data in place of the old: If new data comes in after an encounter is completed, it will switch out the new data with original data 
  • Ex: Fitbit participant doesn't sync their device until the following day, WTH will replace the '0 steps' with the # of steps that they walked
• Stick with our original data: WTH should leave the original data that attached to the encounter
  • Used for medication adherence devices, SMS 
    

11. Apply feedback... indicates what action WTH should take following new data

• Only the first time data attaches: If any new data comes in during an encounter window that has already been completed, WTH will not do anything. 
• Each time a new data point attaches to an encounter: If any new data comes in during an encounter window that has already been completed, WTH will reapply feedback on the encounter for each data entry

Creating a Data Source

To create a new data source, you can go to the Data Sources tab under Manage Study, then create a data source from the following types:

1. Surveys/Forms - Learn about building surveys here: Building: Surveys

2. Devices - For physical devices

3. SMS/Other - For data sources that aren’t surveys or physical devices

   1. Clarity - Custom Data Source (via API)

   2. Clinstream

   3. PennchartX ADT feeds

   4. Custom Data Source (Manual Upload): CSV File Import

Adding a New Device

For a list of our supported devices, look here: https://waytohealth.atlassian.net/wiki/spaces/BG/pages/2567110660/Supported+data+sources#%5BhardBreak%5DConnected-Devices

The first step to setting up a device integration is to select which device you are trying to collect data from:

...

Once a device has been selected, you will be presented with any additional pieces of information that may be required for Way to Health to interact with that device vendor. This is usually either a key provided by them for authentication or a username/password.

About Device Authorization

Some devices are authorized by the participant during enrollment (e.g. Fitbit and Withings) while others are authorized at the study level (e.g. Adheretech). For devices that are authorized by the participant during enrollment, you will want to add a Device Authorization Enrollment Step to the study configuration.

Once you have configured a device, you can begin building tools to use the data: How to Use Device Data
