Case Study: Security & HIPAA
By Maddi Merrill
Working with Amazon Web Services and 1Strategy, the Cambia Health Data Sciences teams have been able to deploy HIPAA compliant and secured AWS EMR data pipelines.
Cambia Health Solutions, headquartered in Portland, Oregon, comprises more than 20 companies, all focused on creating a more person-focused and economically sustainable system. Among their numerous Direct Health Solutions companies, they bring transparency to 100 million consumers in 50 states (HealthSparq), provide a direct-pay health care marketplace for high-deductible health plan members (SpendWell), and encourage healthy behaviors through a gamification-and-technology-driven wellness solution (hubbub). They have six health plans in four states, providing insurance to more than 2 million people, and offer best-in-class member satisfaction as measured by Forrester CXi.
Cambia Health was faced with two main challenges:
- Unacceptable length of time for their claims processing system to analyze large datasets
- Inefficient management of analytics platforms due to challenges associates with having multiple systems with varied components spread across several different sets of servers, all while maintaining HIPAA Compliance
Why Amazon Web Services
Working with Amazon Web Services and 1Strategy, the Cambia Health Data Sciences teams have been able to deploy HIPAA compliant and secured AWS EMR data pipelines. The data pipeline is secured end-to-end with encryption, applied at-rest and in-transit from the S3 data lake to the EMR cluster and back to an S3 bucket hosting processed data. The ability to utilize these AWS cloud services in a HIPAA compliant mode for Data Analysis pipelines has led to increased productivity with ongoing projects, as well as opened the door for Cambia data scientists to explore new friction points within the healthcare domain.
Cambia solicited 1Strategy because of their unique focus on transformation and their depth of knowledge in leveraging the platform services of the AWS ecosystem, as well as their experience with sensitive HIPAA workloads. 1Strategy can quickly distill requirements, provide design expertise, and complete automation projects in a fraction of the time estimates provided by their competitors.
The Benefits of AWS and 1Strategy
The elasticity of the EMR platform allows the data science team to prototype, research, and refine analytics products on the same software stack available for full-scale production in a seamless manner. The parity of environments throughout the development cycle has reduced difficult to diagnose environmental issues, had increased collaboration between the data science and engineering teams, and has allowed a more wide-spread adoption of best practices.
“Because we were new to the AWS cloud space, we engaged 1Strategy to help jump start a few initiatives and provide mentoring and knowledge transfer to staff,” said Scott O. Lukas, Cloud Network Architect of Cambia Health Solutions. “Working side by side, we were able to complete our initial IaC (Infrastructure as Code) implementation of EMR (Elastic Map Reduce) and were able to stand up cross account ADFS (Active Directory Federation Service) allowing us to centrally control account access authentication.”
The 1Strategy team helped Cambia design, codify, and deploy the services required by Cambia to enable rapid deployment of the AWS services required for the Cloud Data Lake in less than 10 minutes – including EMR clusters and all supporting services.
Lukas added, “I appreciated how eager 1Strategy was to engage with us, openly sharing their knowledge and diving in to help find answers to our questions. I would happily partner with them again in the future.”
Due to the success of this project, 1Strategy and Cambia were invited to share this experience at AWS re:Invent 2016. The session, Data Science and Healthcare: Running Large Scale Analytics and Machine Learning on AWS (below), was about how 1Strategy was able to work with Cambia to deploy HIPAA compliant and secure EMR data pipelines on the cloud, as well as utilize machine learning in reducing Cambia’s cost and improving their quality of care was presented in. The session was so popular that even the requested encore presentation session was full completely full. As a result of this project, 1Strategy was asked to complete three additional Automation, DevOps, and Data projects for Cambia Health.
Decrease Processing Time for Analytics Pipelines
The runtime for key analytics pipeline processing was reduced from over 24 hours to under 2 hours. Tens of millions of medical claims records that had previously been analyzed on their legacy, on-premises infrastructure were analyzed on AWS by leveraging modestly sized Amazon Elastic MapReduce (EMR) clusters (less than 10 nodes of m4.large instances) and built on out-of-the-box EMR images. The EMR toolset allows data scientists to seamlessly apply high-level programming languages to problems throughout the feature engineering pipeline, resulting in more nuanced features which better capture the complexities of the healthcare domain.
Additionally, the decreased time devoted to pipeline management allows the team to dedicate additional iterations toward building and tuning analytics solutions, increasing the leverage of the data science team.
EMR provided a flexible processing platform for all data-centric applications in the cloud. Leveraging the high-level languages supported by EMR and the native Hadoop integration, the data science team is able to feed downstream systems reliably without the need for intermediate data formatting and storage.
The ability to customize the contents of the EMR machines has allowed the DS team to move workloads previously spread across multiple servers containing separate software components to a single, orchestrated set of machines for use cases including clinical prediction, speech-to-text transcription, and natural language processing. Combining analytics toolsets such as the Python PyData Stack and R with Big Data Frameworks (primarily Spark) has provided the capability to complete data exploration, feature engineering, and applied analysis on a single stack and has vastly improved the efficiency of the team.
