“There have been a handful of cases which have now held, for one reason or another, that a third party can pursue a claim against a health care practitioner if they were injured as a result of that health care practitioner’s negligence to his or her own patient. What does this mean practically speaking? It opens the door for more lawsuits, lawsuits from people who were never your patient, but who may be impacted by a prescribing decision you make for your patient.”
