• 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.
