Understanding the data schema

To use the data from the Awell platform, it's essential to understand some Awell terminology first.

Below, we explain the terminology that you'll find back in the data schema. If you have any further questions about this, please contact your Awell Customer Success Manager.

Care flow definition vs Care flow

In the Awell domain, a care flow definition is a care flow template designed in the Awell Studio, representing the general structure and components of a care plan without being tied to any specific patient.

A care flow on the other hand is a patient-specific instance derived from a care flow definition that tracks and manages an individual patient's care journey. For example, if you created the care flow definition "post-operative follow-up" in Awell Studio, all your patients that get included in this care flow definition will have an individual care flow.

Data point definition vs Data point

Similar to care flow definitions and care flows, a data point definition is a care flow component as designed in Awell Studio while a data point is the patient-specific instance of that data point definition. For example, if you collect the weight of a patient in a care flow, the data point for a specific patient could be 80 kg (or 176lbs).

Data point keys

To avoid having to work with randomly generated IDs for data point definitions, we allow users to define a human-readable identifier in Awell Studio for all data point definitions. In the data repository, we combine this human-readable identifier with the source to form a 'key'. Let's imagine that you are building a patient form to collect the patient's weight and height, with the intent of calculating a BMI score. You set the form key to bmi, and set the question keys to height and weight respectively. This will result in data point definitions with the following keys:

• bmi.height contains the answer to the height question in the bmi form
• bmi.weight contains the answer to the weight question in the bmi form

Release vs. Version

In Awell Studio you can see the list of published versions for a given care flow definition with an auto incremented version number. This version number is only used for display purposes. Behind the scenes we assign a unique release identifier to each published version, which you can retrieve through the Get published pathway definitions query.

The release identifier is guaranteed to be globally unique so it can be safely used as input to build analytics query on the data set.

Schema

The data repository contains three different types of data: data points, orchestration data and patient data.

Data points refers to any atomic piece of data collected from a user or system in care flows (e.g. form responses, calculation results, etc.). These are the datapoints that you can find in the data catalog in Awell Studio and that you can use to build care flows.

Orchestration data refers to data generated by the orchestration of the care flow itself, i.e. data about which actions were orchestrated when in care flows.

Patient data refers to the data you explicitly provide on the patients you enroll in your care flows. When using anonymous patients this only contains identifiers.

Data points

The data points are stored in two tables: data_points and data_point_definitions. The data_points table uses a normalized structure to handle the fact that atomic data can have different value types (string, boolean, numeric, date etc), and can come from many different sources (forms, calculations, Extensions, etc.).
