A recent article from the Institute for Safe Medication Practices (ISMP) that our Maryland-based medication error attorneys have been reading reported that the order management scanning system (OMSS) technology that was created to improve the efficiency and safety of the drug ordering process for doctors and pharmacies, is now experiencing error-prone problems that are leading to medication errors, drug omissions and missed drug therapy in patients.
OMSS is a technology that was created to capture a digital image of a handwritten or printed prescription order and send it to the pharmacy—eliminating faxing, the use of a courier, or the use of pneumatic tubes to transport the information to the pharmacist. The idea behind OMSS was to accelerate the time the prescription hit the pharmacy, speed up the prescription filling process, with electronic filling, easy retrieval of scanned orders, and reduce the risk of transcription errors because the order can be magnified. Unfortunately, according to the article, these OMSS benefits are null and void if the pharmacy never receives the prescription orders.
The problem that is reportedly occurring is that multiple pages of orders are being pulled through the scanner at the same time, and the scanner is only reading a single page at a time—a problem that has also plagued pharmacies with faxing or copying orders in the past. When this problem occurs, staff may not be aware that only one page was scanned, and the pharmacist may not be aware that they should have received multiple pages of orders. As a result, drug omissions can take place, leading to medication mistakes or missed drug therapy.
In one documented case, a physician wrote three pages of admission orders for a patient suffering from lung cancer, as well as difficile colitis and fever. When the orders were scanned with OMSS, the pharmacy only received two pages of the orders, because one page was not pulled through. Neither the nurse who administered the medication the physician, nor the pharmacist noticed the prescription error and omission. The drugs prescribed on the missing page were seizure medications. By the forth day of receiving only a fraction of the medication, the patient was exhibiting behavior that lead the emergency response team to determine that the patient was having a seizure. The patient was transferred to critical care unit, where the doctor figured out the pharmacy mistake, and although the patient required intubation, he ultimately experienced a full recovery.
