The impact of electronic health record interoperability on safety and quality of care in high-income countries: systematic review.
Electronic health records (EHR) systems frequently interact with EHRs in other organizations, between clinical settings (e.g., in-patient and out-patient), or with devices (e.g., smart pumps). In this review, 12 studies were identified that examined the effect of EHR interoperability on patient safety. While EHR interoperability was shown to improve patient safety, outcome measure heterogeneity limits measuring true effects.
