Handwritten prescription slips have always presented risks to patients. The risk of a pharmacist or pharmacy technician misreading a doctor’s handwriting, sometimes known as “chicken scratch” among pharmacists, leads to the risk of a misfilled prescription. This could involve the wrong dosage of a drug, or the wrong medicine entirely, with the consequences ranging from adverse side effects, worsening of a patient’s condition, or even death. New computerized systems for doctors and other medical professionals, however, join the ever-increasing number of electronic solutions to common human errors. These systems can help combat not only pharmacy errors, but also prescription fraud and prescription drug abuse.
Electronic prescriptions, or e-prescriptions (e-Rx), allow a doctor to write a prescription by submitting a request to a pharmacy online, rather than writing out the prescription on a prescription pad. A 2010 study mentioned by the New York Times, which examined handwritten prescriptions from doctors, physician assistants, and nurse practitioners in New York, found a thirty-seven percent error rate for handwritten prescriptions, not including legibility errors. The study found legibility errors in eighty-eight percent of the handwritten prescriptions. These errors can result in a patient receiving the wrong dosage or the wrong medication. They may also result in the pharmacy needing extra time to consult with the prescribing doctor or professional to sort the matter out, which could cause harm to a patient in urgent need of a particular medication.
Congress promoted the use of e-Rx in the 2009 Health Information Technology for Economic and Clinical Health Act (HITECH Act), passed as part of that year’s economic stimulus bill. The HITECH Act establishes certain acceptable uses for electronic medical records, giving regard to issues of patient privacy and the security of patients’ personally identifying information. It specifically names e-Rx as an approved use.
