Why must the EDIS and perioperative IS query the HIS when new patients
are registered in its system?

Answer 50

Because the MPI is located on the HIS and the MPI must be queried to ensure there is no duplication of an MPI entry.

Answer 53

An ADC sends a credit message when a patient is charged for medicine he did
not consume.

Question 54

Why is the LIS usually more complex than other clinical information systems?

Answer 54

Because there are many components that run a lab and each have a special and
unique responsibility for fulfilling lab orders.

Question 55

Assume the pharmacy data flow shown in Figure 2-12 still uses paper for receiving orders. How might that affect the flow of data? A healthcare provider would not enter the order in the HIS. Redraw the diagram and
indicate that paper is used for direct input into the pharmacy IS. Rewrite the steps to reflect these differences.

Answer 55

Step 1. The pharmacy receives an order via fax, phone, written, and so on.
Step 2. The pharmacy IS sends an order message to the HIS and the ADC through the interface engine.
Step 3. The order can be viewed in the physician portal.
Step 4. When the healthcare provider collects and administers the
medicine, the dispense information is sent from the ADC to the pharmacy IS through the interface engine.
Step 5. The pharmacy IS charges at the time the medicine is dispensed.
The pharmacy IS sends charges to the HIS through the interface
engine.
Step 6. The eMAR is updated.
Step 7. ADC medication credits for ordered yet unused medicine are sent to the pharmacy IS and then to the billing component of the HIS
through the interface engine.
