According to a recent study, poison control centres in the US receive a call about medication errors every 13 seconds, and that rate has doubled in the past 12 years (1). Doctors, nurses and nurse-practitioners prescribe medications (and more recently focus on de-prescribing many drugs) on a daily basis, largely without a second thought. These medicines change the lives of our patients every day – often for the better, but unfortunately sometimes for the worse. Given the power of drugs and the authority we wield every time we sign our name to a prescription, it’s important that we do everything we can to focus on safety and effectiveness.
Most prescribers become familiar enough with a handful of different medicines to confidently prescribe them without risk. But sometimes we introduce a distinct cognitive bias by extending our comfort level with one set of drugs to others, including rare, unfamiliar and dangerous ones. It is impossible for any human being to remember all the details of side effects and interactions for the thousands of medications we are thought to be experts on when we prescribe. Add in the notion that individual genetics dictate the way or bodies consume and dispose of medications, and it’s easy to see how this overconfidence and generalization can have dramatic consequences for patients.
Fortunately, there are systems and processes in place that lower our risk of error dramatically. Computerized provider order entry applications like e-prescribing involve electronic entry and transmission of medical orders, and have been found to reduce medication error rates by over 50%.(2) The EMRs used by most community-based physicians in Canada have built-in interaction checkers that compare not only drug-to-drug interactions, but also drug-to-disease-state interactions. And they will alert us when a potential problem arises – assuming we are using the most current version of our EMR and drug database, and have not turned off alert capabilities due to information overload.
While we certainly don’t want our prescription modules to alert us incessantly, we do need to understand the likelihood of severe interactions every time we prescribe. Reminder alerts can also be set up in the EMR for therapeutic monitoring, which is frequently forgotten when prescribing titrated drugs like lithium or anti-seizure meds. It may also be worthwhile to incorporate alerts regarding Beers List drugs that should never be prescribed to elderly patients.
Of course, these types of alerts are only as reliable as the accuracy of the patient information and medication lists in our EMR. So, it’s important for every provider to take the time needed to update medication lists at every patient visit, whether or not it’s considered our direct responsibility to do so.
Tools like EMR, CPOE and automated alerts represent the tipping point in our ability to avoid medication errors using digital health. But there’s more on the horizon. Integration of province-wide databases such as the Digital Health Drug Repository, Digital Health Immunization Repository and Narcotics Monitoring System through the ConnectingOntario and Clinical Connect viewers will be a huge leap forward, giving us the ability to review medications prescribed and dispensed from all practitioners involved in a patient’s care. Integrating this information into EMR prescribing modules will have an even greater impact.
The ability to quickly view and analyze data across our entire patient roster will soon be possible for all using the OntarioMD EMR dashboard.. Work being done on the EMR dashboard – in partnership with Health Quality Ontario, the Ontario College of Family Physicians, the Association of Family Health Teams of Ontario, Association of Ontario Health Centres and the College of Physicians and Surgeons of Ontario – will make it easier to track drugs of interest among our own patients, and will provide a practice-wide population health perspective. This becomes imperative when considering high risk prescribing scenarios like narcotics doses above 50 morphine mg equivalents per day, in immunocompromised patients, and for those on multiple medications with more than one complex chronic disease.
Important digital tools, combined with appropriate policy, education and advice on how to cautiously prescribe and monitor risky drugs, have the potential to help us stave off adverse reactions, overdoses and even deaths. But we must also focus on ensuring that we understand new prescribing guidelines, screen for misuse, employ narcotics contracts and periodically review long-term medication use with patients as diligently as we analyze new drug starts.
With the privilege of prescribing comes great responsibility. Thinking about prescribing safely at the point of care and asking ourselves if we’ve taken advantage of every tool available to make this work easier will give us the best chance we have in doing the right thing for our patients, our practices and ourselves.
