Streamlining Healthcare Connectivity with an Enterprise Data Hub
The connectivity and information technology subsidiary of a major pharmaceutical company was created to simplify how the business of healthcare is managed while making the delivery of care safer and more efficient. As more and more of the US’ healthcare system goes electronic, this organization meets challenges and opportunities through an open network that supports future growth via interoperability among organizations, systems, and solutions.
With regulations such as the Health Insurance Portability and Accountability Act of 1996 (HIPAA), healthcare organizations are required to store healthcare data for extended periods of time. This health IT company instituted a policy of saving seven years’ historical claims and remit data, but its in-house database systems had trouble meeting the data retention requirement while processing millions of claims every day.
A software engineer at the company explained, “All of our systems were maxed out. We were constantly having database issues. It was just too much data for what they were meant to handle. They were overworked and overloaded, and it started to cause problems with all of our real-time production processing.”
Further, the organization sought a solution that would allow users to do more than just store data. The manager of software development at the company explained, “In today’s data driven world, data really is this huge asset. We wondered, ‘What framework, what platform will allow us to optimize the data that we have without compromising our stringent corpo - rate and regularity driven compliance guidelines?’”
The team set out to find a new solution. “We could have gone the SAN route, but it’s expensive and cumbersome,” said the software engineer. They did some searching online and came across Apache Hadoop, MongoDB, and Cassandra. “We analyzed them and came up with a prototype for each one. In the end, we decided Hadoop was what we wanted.”
Initially the organization downloaded Hadoop from Apache and configured it to run on ten Dell workstations that were already in house. Once the small Hadoop cluster showed its functionality and demonstrated value, the team decided to make a commitment to the platform, but would need support to do so. When evaluating various Hadoop distributions and management vendors, they recognized that Cloudera was different: its Hadoop distribu - tion—CDH—is 100% Apache open source. This allows Cloudera customers to benefit from rapid innovations in the open source community while also taking advantage of enterprise- grade support and management tools offered with the Cloudera Enterprise subscription. And with Cloudera Enterprise Data Hub Edition, the company could deploy a centralized big data platform supporting a variety of different users and workloads.
But the risk and compliance team required encryption of regulated data for project approval. Homegrown and open source encryption solutions proved impractical to implement. Evalu - ation also showed them to be expensive, complex, and restrictive to deploy, configure, and maintain. Thales eSecurity, a certified Cloudera partner, was selected as the best solution. Critical considerations supporting the decision were Thales eSecurity's single, centrally managed encryp - tion and key management infrastructure, transparency to Cloudera's big data operations, and extensibility to support additional applications and future requirements.
When deciding to deploy CDH, the team set out to identify applications that were already seeing performance issues in production. “One of the big advantages of Hadoop has been its ability to segregate big data from transactional processing data and allow smoother processing of information. Basically, it allows us to offload a lot of stress from the database,” said the company’s manager of software development.
They quickly identified two areas that were a strong fit for Cloudera and Thales eSecurity:
- Archiving seven years’ claims and remit data, which requires complex processing to get into a normalized format, and encrypting that data in a solution that meets future requirements to restrict privileged user access to data at the underlying file system and volume level
- Logging terabytes of data generated from transactional systems daily, and storing them in CDH for analytical purposes
Today the health IT organization uses Flume to move data from its source systems into the Cloudera cluster on a 24x7 basis. The company loads data from CDH to an Oracle online transaction processing (OLTP) database for billing purposes. This load runs once or twice each day via Sqoop. The Thales eSecurity solution assures encryption and compliance of all regulated data through centrally managed policies.
Impact: Helping Provides Collect Payment Faster Through Operational Efficiencies
“If you look at the margin that the average hospital has, it’s between 2-3%,” stated the manager of software development. “So their cash flow is very tight. Anything you can do to reduce the time to get paid is very valuable to a healthcare provider.”
Since deploying Cloudera Enterprise, the organization has reduced the time it takes for healthcare providers to get paid by streamlining their transfer of messages to payers. The ability to expedite this process is especially valuable when regulatory changes come into play, such as the recent conversion from HIPAA 4010 to HIPAA 5010.
“We assist with the conversion and processing of these messages,” said the company’s manager of software development. “For example, 4010 messages came in and we’d convert them to 5010 to allow seamless processing. The providers didn’t have to upgrade any of their systems when the regulations went into effect. We gave them a bit of a buffer to implement changes. And since we do a lot of electronic processing, we can do basic sanity checks on the messages as they come in and let providers know what adjustments need to be made in order to get paid faster.”
Impact: Low Cost + Greater Analytic Flexibility
Because Hadoop uses industry standard hardware, the cost per terabyte of storage is, on average, 10x cheaper than a traditional relational data warehouse system. “One of my pet peeves is: you buy a machine, you buy SAN storage, and then you have to buy licensing for the storage in addition to the storage itself,” explained the manager of software develop - ment. “You have to buy licensing for the blades, and it just becomes an untenable situation. With Hadoop you buy commodity hardware and you’re good to go. In addition to the storage, you get a bigger bang for your buck because it gives you the ability to run analytics on the combined compute and storage. The solutions that we had in place previously really didn’t allow for that. Even if the costs were equivalent, the benefit you get from storing data on a Hadoop type solution is far greater than what you’d get from storing it in a database.”
Impact: Simple Deployment & Administration
After deciding on the Cloudera solution, “the deployment process into production with Ha - doop was actually quite easy,” said a software engineer at the company. “Cloudera Manager really helped us a lot. It’s as easy as just clicking a few buttons, and you’re up and running. It’s really simple. And the support staff at Cloudera have been great. They really helped us out with a couple of issues we had along the way.”
Similarly, the security team was able to implement the Thales eSecurity solution without the ap - plications group making any changes. There were no process or experience changes required by users or administrators, nor was there any impact to service level agreements (SLAs). Further, the risk and compliance team signed off quickly on the new environment because it was easy to demonstrate the ease of encryption and access control.
Several employees enrolled in Cloudera University training as well, which was “very beneficial” according to one software engineer. And with Cloudera Manager, the team spends very little time managing the cluster.
Further, this health IT organization appreciates the proactive customer support offered by Cloudera Enterprise. “We ask questions and we get them answered very quickly,” com - mented their manager of software development. “Not only do the Cloudera Support folks answer the question, they come back and say, ‘Do you have any other questions? Is there anything else we can help you with?’ It’s very different. The people that are on Cloudera’s Support team — you can definitely tell they are Hadoop Committers. Not only will they find you the answer but they can tell you, ‘This may not be the best practice, you may want to change the way you’re doing your development to take advantage of other features.’ The Cloudera Support organization is world class.”
