I think the role of health informatics is to bring doctor-patient communications to the next level and promote patient-centered oriented care. This type of care is an important element of high-quality care. “Informatics can provide a mechanism for patients to provide their clinician(s) with critical information and to share information with family, friends, and other patients” (Snyder, 2011). The doctor can share healthcare information or electronic medical records with another doctor. Patient and doctor can use communication tools and resources to interact in new ways. This type of communication is warranted to avoid reliance on implicit, uncompleted, or inappropriate data. I think the greatest challenge for both providers and patients is to identify need information to exchange their interactions.Health Information Technology (HIT) includes significant saving. The idea behind this is to perform same work with fewer resources. The largest saving comes from a reduced hospital stay. It can lead to increased safety, better coordination, and scheduling. It also includes much more efficient drug utilization and reduced nurses administrative time. HIT helps to manage and recommend preventive services, such as screening, well visits, lab works, and vaccinations. Another big part of saving very visible when HIT facilitate chronic-disease management. The HIT based system can quickly identify needs for patients to conduct a test and can insure consistent recording of results. Patients can remotely transfer their vital signs from home to their doctor or provider. This is in direct ratio help to reduce the need for hospitalization, thereby both improving health and reducing costs.As I sad before HIT can lead to increased safety. 1st is an ability to use alerts and reminders. That activity can be generated by a computerized system. For example, it can prevent a potential adverse reaction to the patient prescribed drug (www.rand.org, 2005). Another very important safety point will around enhance health. The provider can improve intervention between multiple health problems like disease prevention and chronic-disease management. The combination of preventive services can increase healthcare expenditures. The cost those types of activities not large, but the health benefits of improved prevention are significant.
