Physician portal

Most commercial EHRs combine data from the large ancillary services, such as pharmacy, laboratory, and radiology, with various clinical care components such as nursing plans, medication administration records, and physician orders. The number of integrated components and features involved in any given situation would depend on data structures and systems used. The EHR may import data from the ancillary systems via a custom interface or may provide interfaces that allow clinicians to access the silo systems through a portal. The EHR may incorporate only a few ancillaries. 

Commerce includes platforms such as portals for online buying and selling, which provide clinical and business transactions capability for treatments, lab tests, invoicing, ordering, and payments. Online care is the capability to provide interactions between physicians, as diagnosis and treatments often require ability to extract expert knowledge available within specialist domains.
