The best characteristic of Epic is the ability to access records, data, and exam information from other healthcare providers. It also allows for the connection between different speciality areas by including their contact info, their name, and what their plan is. As a physical therapy student doing my clinical at Barnes Jewish, it's amazing to be able to look at notes from a rehab, other hospital, PCP, LTAC, or nursing home to learn more about the patient
The worst thing about Epic is the amount of time it takes to learn the system. It can also take some time to determine where exactly you can find certain information based on how long you have been using the software.
The ability to communicate and learn from other health care providers. The ability to look back at prior hospitalizations/ encounters to determine history, prior level of function, and course of care. Another benefit is the fact that you can look at vitals or neuro checks taken by the nurse overnight in case the nursing shifts have changed and you would like to see what the other nurse saw.
