I think the role of health informatics is to bring communications between doctor and patient to the next level and promote care as patient-centered approach. The very important element of this care is care based on high quality. “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. Communication tools can be used by patient and doctor to view and review resources to interact in new ways. This type of communication is warranted to avoid reliance on implicit, uncompleted, or inappropriate data. I think the biggest challenge for both doctors and patients is exchanging their interactions based on the identified important information.Health Information Technology (HIT) includes significant saving. The idea behind this is to perform same work with fewer resources. The reduced hospital stay comes as biggest saving. It can lead to superior coordination and scheduling, and most importantly it can increased safety. It also includes much more efficient medicine utilization and reduced nurses management 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 support chronic-disease administration. The HIT based system can fast identify needs for patients to complete a test and can ensure serial recording of results. Patients can remotely transfer their vital signs from home to their doctor or provider. This is in direct ratio help to remove the need for hospitalization, thereby both minimizing costs and enhance patient health.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 expenses. The cost those types of activities not large, but the health benefits of improved prevention are significant.
