Cascade in use

Apps using Cascade, and exactly how.

Small apps collect one kind of data well. Cascade Workbench is where it comes together for the family. Each entry gives its stage, what it uses, and what it stores.

Live · early testing

Collector

Full Picture

Parents of a child being evaluated for ADHD collect rating forms from teachers, coaches and family, and bring one packet to the doctor.

fullpicture.family

Uses: Cascade's pod-encryption format and its conformance test vectors.
Stores: Sealed answers it can't read, deleted 30 days after the back-by date.
Next: Writes each family's answers as Cascade records, for their own pod. In progress.

In development

The record

Cascade Workbench

A desktop app where a caregiver gathers a family's records, learns what they say with answers that cite the records, and prepares for appointments. A research helper, never a diagnosis tool.

Uses: The Cascade CLI alongside the app, to import, validate and query.
Stores: Pods on the caregiver's own computer. Connects to MyChart through SMART on FHIR.
Next: Takes in records from collectors such as Full Picture, beside the clinical record.

Case study · App page

Uses: The pots vocabulary, through an early, private Swift implementation.
Stores: Test results as encrypted files on the phone. No health data is sent; usage analytics are optional.

Design · not built

A design for a whole-record patient app, submitted to the ONC EHIgnite Challenge. It wasn't selected, and the app hasn't been built.

Today: The name refers to Cascade's format-conversion layer: FHIR and C-CDA in and out.
