The pharmacy dispenses about 3,000 different prescription medications of various kinds. Every
prescription is associated with one patient, and is logged by the dispensing clinic. The new
administrator wants to know which drugs are most prescribed, and also which are the most
profitable.
The following is some general information about the organization and its current processes.
• The hospital operates three clinical facilities.
• A healthcare worker logs in at a facility at the start of a shift and logs out at the end.
• The name, address, Social Security number and other information is recorded for every
healthcare worker.
• All healthcare workers have one billing rate, which is determined by their job description.
• Each medication dispensed by prescription is linked to both the prescription number and the
medication ID number, recording the item price and the quantity dispensed.
As a convenient and affordable means of providing hospice care, palliative care, and
convalescent care to patients that need occasional/intermittent skilled nursing, but do not
require hospitalization, the hospital offers limited in-home care. Recording of in-home care
includes the healthcare worker ID, their departure time and return time, and also the
prescription ID for any prescriptions administered by the healthcare worker in the home
setting.
The hospital administrator would like to know what home-care visits have been made to whom,
by whom, when, and how long they took. There is concern at this point that the cost of
providing limited home healthcare is not providing adequate return on investment, and the
program should be revised or discontinued.
