Case Study: Leading U.S. Healthcare Network restores rapid EHR access and accelerates patient care with NETSCOUT nGeniusONE

NETSCOUT Visibility at Remote Clinic Helps Diagnose Application Latency

A leading U.S. healthcare network with a 75-year history serving millions across multiple states was experiencing intermittent slowdowns in its electronic health record (EHR) application reported by doctors at a remote clinic. IT teams lacked end-to-end visibility at the clinic—initial monitoring from data centers and colocation sites was inconclusive—so the issue escalated to a War Room after weeks of impact to productivity and patient care.

NETSCOUT deployed nGeniusONE with InfiniStreamNG/Remote ISNG, vSTREAM virtual appliances, and packet flow switches to add DPI at the clinic. The remote ISNG revealed that toolbar requests were taking extra hops through an Equinix co-lo and the public cloud, causing ~10-second delays due to an application routing/coding error; the vendor corrected the bug. The team pinpointed the root cause in under an hour, restored EHR responsiveness, improved staff productivity, enabled more patient visits (and revenue), and reduced MTTK/MTTR and reliance on costly War Rooms.
