My wife is dealing with cancer and associated complications at three distinct hospitals and a national cancer center.

The two hospitals on Epic are great - all of her records are immediately exchanged. The third hospital has a shitty cerner system and has problems sharing between departments. The cancer center has an excellent patient portal but doesn’t integrate.

Ultimately these problems are difficult as the creation of Medicare and Medicaid happened during the early days of computing. So we’re stuck with 75 years of legacy.
