At AWS re:Invent 2020, we previewed Amazon HealthLake, a completely managed, HIPAA-eligible service that permits healthcare and life sciences prospects to mixture their well being data from totally different silos and codecs right into a structured, centralized AWS information lake, and extract insights from that information with analytics and machine studying (ML). At the moment, I’m very completely happy to announce that Amazon HealthLake is usually accessible to all AWS prospects.
The power to retailer, rework, and analyze well being information rapidly and at any scale is important in driving high-quality well being choices. Of their every day observe, docs want a whole chronological view of affected person historical past to determine one of the best plan of action. Throughout an emergency, giving medical groups the fitting data on the proper time can dramatically enhance affected person outcomes. Likewise, healthcare and life sciences researchers want high-quality, normalized information that they will analyze and construct fashions with, to determine inhabitants well being tendencies or drug trial recipients.
Historically, most well being information has been locked in unstructured textual content corresponding to scientific notes, and saved in IT silos. Heterogeneous functions, infrastructure, and information codecs have made it troublesome for practitioners to entry affected person information, and extract insights from it. We constructed Amazon HealthLake to unravel that drawback.
Should you can’t wait to get began, you possibly can bounce to the AWS console for Amazon HealthLake now. Should you’d prefer to study extra, learn on!
Introducing Amazon HealthLake
Amazon HealthLake is backed by fully-managed AWS infrastructure. You gained’t have to acquire, provision, or handle a single piece of IT gear. All it’s a must to do is create a brand new information retailer, which solely takes a couple of minutes. As soon as the information retailer is prepared, you possibly can instantly create, learn, replace, delete, and question your information. HealthLake exposes a easy REST Utility Programming Interface (API) accessible in the most well-liked languages, which prospects and companions can simply combine of their enterprise functions.
Safety is job zero at AWS. By default, HealthLake encrypts information at relaxation with AWS Key Administration Service (KMS). You need to use an AWS-managed key or your individual key. KMS is designed in order that nobody, together with AWS workers, can retrieve your plaintext keys from the service. For information in transit, HealthLake makes use of industry-standard TLS 1.2 encryption finish to finish.
At launch, HealthLake helps each structured and unstructured textual content information sometimes present in scientific notes, lab studies, insurance coverage claims, and so forth. The service shops this information within the Quick Healthcare Interoperability Useful resource (FHIR, pronounced ‘hearth’) format, a normal designed to allow trade of well being information. HealthLake is suitable with the most recent revision (R4) and presently helps 71 FHIR useful resource sorts, with further assets to comply with.
In case your information is already in FHIR format, nice! If not, you possibly can convert it your self, or depend on associate options accessible in AWS Market. At launch, HealthLake consists of validated connectors for Redox, HealthLX, Diameter Well being, and InterSystems functions. They make it straightforward to transform your HL7v2, CCDA, and flat file information to FHIR, and to add it to HealthLake.
As information is uploaded, HealthLake makes use of built-in pure language processing to extract entities current in your paperwork and shops the corresponding metadata. These entities embrace anatomy, medical circumstances, remedy, protected well being data, check, remedies, and procedures. They’re additionally matched to industry-standard ICD-10-CM and RxNorm entities.
After you’ve uploaded your information, you can begin querying it, by assigning parameter values to FHIR assets and extracted entities. Whether or not it’s essential entry data on a single affected person, or need to export many paperwork to construct a analysis dataset, all it takes is a single API name.
Let’s do a fast demo.
Querying FHIR Information in Amazon HealthLake
Opening the AWS console for HealthLake, I click on on ‘Create a Information Retailer’. Then, I merely decide a reputation for my information retailer, and determine to encrypt it with an AWS managed key. I additionally tick the field that preloads pattern artificial information, which is a good way to rapidly kick the tires of the service with out having to add my very own information.
After a couple of minutes, the information retailer is lively, and I can ship queries to its HTTPS endpoint. Within the instance under, I search for scientific notes (and scientific notes solely) that comprise the ICD-CM-10 entity for ‘hypertension’ with a confidence rating of 99% or extra. Underneath the hood, the AWS console is sending an HTTP GET request to the endpoint. I highlighted the corresponding question string.
The question runs in seconds. Analyzing the JSON response in my browser, I see that it accommodates two paperwork. For each, I can see plenty of data: when it was created, which group owns it, who the writer is, and extra. I also can see that HealthLake has routinely extracted a protracted checklist of entities, with names, descriptions, and confidence scores, and added them to the doc.
The doc is hooked up within the response in base64 format.
Saving the string to a textual content file, and decoding it with a command-line software, I see the next:
Mr Nesser is a 52 12 months previous Caucasian male with an intensive previous medical historical past that features coronary artery illness , atrial fibrillation , hypertension , hyperlipidemia , offered to North ED with complaints of chills , nausea , acute left flank ache and a few numbness in his left leg
This doc is spot on. As you possibly can see, it’s very easy to question and retrieve information saved in Amazon HealthLake.
Analyzing Information Saved in Amazon HealthLake
You may export information from HealthLake, retailer it in an Amazon Easy Storage Service (Amazon S3) bucket and use it for analytics and ML duties. For instance, you could possibly rework your information with AWS Glue, question it with Amazon Athena, and visualize it with Amazon QuickSight. You may additionally use this information to construct, prepare and deploy ML fashions on Amazon SageMaker.
The next weblog posts present you end-to-end analytics and ML workflows based mostly on information saved in HealthLake:
Final however not least, this self-paced workshop will present you the way to import and export information with HealthLake, course of it with AWS Glue and Amazon Athena, and construct an Amazon QuickSight dashboard.
