Successful implementation of a comprehensive computer-based patient record system in Kaiser Permanente Northwest: strategy and experience.

Kaiser Permanente Northwest (KPNW) has implemented a computer-based patient record (CPR) system for outpatients. Clinicians at KPNW use this comprehensive CPR to electronically document patient encounters; code diagnoses and procedures; maintain problem lists; order laboratory tests, radiology tests, and prescriptions; and send patient-specific messages and referrals to other medical providers. More than 700 clinicians, representing more than 20 medical and surgical specialties, and 2600 support staff in 31 geographically separate sites use this system as the information foundation of delivery and documentation of health care for KPNW's membership of 430,000. As of May 1998, more than four million visits and two million telephone calls had been processed and documented into the system. More than 5000 outpatient visits are processed and documented each weekday. From an integrated clinical workstation, clinicians also access e-mail, an extensive results-reporting system, and sites on both the internet and KPNW's intranet. This article describes a strategy for and experience with the implementation of a large-scale, comprehensive CPR in an integrated HMO. This information may be useful for persons attempting to implement CPRs in their own institutions.
