Case Study –

The pharmacy at Mercy Hospital fills medical prescriptions for all hospital patients and distributes these medications to the nurse stations responsible for the patient’s care. Prescriptions are written by doctors, filed in the patient’s file, and then sent to the pharmacy. A pharmacy technical reviews each prescription and sends it to the appropriate pharmacy station. Prescriptions for drugs that must be formulated (made on-site) are sent to the lab station and prescriptions for off-the-shelf drugs are sent to the shelving station. At each lab or shelving station, a pharmacist reviews the order, checks the patient’s file to determine the appropriateness of the prescription, and fills the order if the dosage is at a safe level and it will not negatively interact with other medications or allergies indicated in the patient’s file. If the pharmacist does not fill the order, the prescribing doctor is contacted to discuss the situation. In this case, the order may ultimately be filled, or the doctor may write another prescription depending on the outcome of the discussion.
Once filled, a prescription label is generated listing the patient’s name, the drug type and dosage, and expiration date, and any special instructions. The label is placed on the drug container, and the order is sent to the appropriate nurse station. Finally, a patient medication report including the patient’s admission number, the drug name and the number of refills, plus the cost of the prescription is then sent to the billing department.

Patient safety is the first priority at Mercy Hospital. The pharmacists at Mercy Hospital follow a standard procedure when evaluating the appropriateness of prescriptions. When a pharmacist initially reviews a prescription, he/she first checks if the dosage is set at a safe level. If the dosage is not set to a safe level, the doctor who prescribed the medication is immediately contacted. Furthermore, the pharmacist proceeds to evaluate the patients’ medical history. If the patient is currently taking any medication that may cause an adverse reaction with the prescription, the doctor is also contacted to discuss alternatives. In addition, Mercy Hospital maintains a list which defines “potentially dangerous” drugs in order to satisfy legal requirements. Any drug on this list may cause clinically significant adverse reactions under certain conditions. Due to these regulations, the pharmacist must attach a boxed warning to the order if the prescription contains one of the drugs on this list. Meanwhile if the age of the patient is 65 or above, a boxed warning must be attached to the order regardless of what drugs the prescription contains.
If all the checks have been completed and the pharmacist does not find any reason to contact the doctor or to attach a boxed warning, the pharmacist declares that the order is a “normal prescription” and no further action has to be taken. Before you implement this process, you want to represent it using process description tools.
