Case Study: Influence Health achieves millisecond search performance and HIPAA-compliant security with Elastic

Influence Health Powering the Search for Better Healthcare

Influence Health is a consumer engagement platform that helps healthcare organizations match patients with the services they need; its products serve 250 clients, 1,100 hospitals and more than 80 million patient records. The company faced a major bottleneck: segmentation and list-building relied on handcrafted SQL queries that could take hours to run and up to two weeks to deliver to customers, forcing the data services team to act as “human-to-SQL” translators.

Influence Health replatformed its search and segmentation onto Elasticsearch (with ES-Hadoop, Spark and Cassandra for ingestion) and adopted X-Pack for encrypted transit to meet HIPAA requirements, supported by Elastic’s customer care. The move cut query times from hours to 7–8 milliseconds, reduced list turnaround to under 10 minutes, freed engineering resources to focus on product development, and benefited from ongoing Elastic support for optimization and upgrades.
