A decade ago, Kaiser Permanente installed the nation’s most comprehensive electronic health record (EHR). The decision was made by the health plan and medical group together. Due to the large size of our organization, implementation was challenging and expensive: The process took two years, and the cost at the time was estimated to be around $4 billion. But there is no question that the price tag and the effort required to train and motivate physicians and staff were worth it. The information the EHR provided, combined with our data analytics and integrated medical care delivery system, has helped us save countless lives.
