Health DataInteroperability

Fostering data interoperability and nurturing FHIR Community

“The HL7 FHIR Foundation is thrilled by this generous contribution of Google Cloud Platform services to support the ongoing activities of the FHIR community to help advance our goal of global health data interoperability,” said Grahame Grieve, HL7 FHIR Foundation Board Member and HL7 FHIR Product Director. “The future of health computing is clearly in the cloud, and FHIR will serve to accelerate this transition.”

ChallengeBridging Chile’s healthcare

Chile’s 1,400 connected health facilities and 1,000 remote medical facilities lacked connectivity – while many of its healthcare systems couldn’t easily, or securely, interoperate.

Previous attempts to resolve failed due to the overwhelming costs and complexity of the solution.

New ApproachDigital Architecture

Nationwide API-based architecture

● Data and applications are easily, yet securely, available

● Enables Public Alerts, Population Health Management Programs, etc

● Connects HC Centers – large and small

● Reinforces and leverages digitizing all clinical and administrative processes

Step 1: Training images from a Dermatology Clinic.

IMPORT: User uploads CSV file with image names and labels into the app

Most popular image file formats are supported (jpg, gif, png, etc.)

LABEL: Images are tagged with “labels” (“Nevus”, “Lentigo NOS”, “Healthy”, etc.)

Step 2: Automatically train ML model

TRAIN: user initiates training of the model

Training takes between 10 min to 24 hours (weeks/months of DIY project)

EVALUATE: Results of the training are shown (Precision, Recall, etc.)

Step 3: Time for predictions

PREDICT: model assigns class probabilities for new images

Prediction only takes seconds

Access: model via UI, command line, or API and integration in Clinical Workflows

Skin disease classification using AutoML

Input:Images with associated “classes”

Model Evaluation Result:Confusion matrix

Prediction:Image classification

Machine learning: from big data to meaningful insights
