The document discusses the use of technology in healthcare, including electronic health records (EHRs) and mobile devices. EHRs can improve patient care by facilitating tasks like prescribing medications, tracking test results, and coordinating care across providers. However, most EHR systems still cannot effectively share information or coordinate care. New technologies like smartphones and social media are also changing how healthcare providers communicate and deliver care. Comprehensive health information technology is needed to support these tools and enable evidence-based shared knowledge and decision making.
