One of the many duties of perioperative nurses is to make sure cases start on time. No matter how full the day's OR schedule, however, they should never rush the informed consent process. Their good intentions of trying to move cases along places them between surgeons and patients, and puts them and your facility at risk of being sued for failing to provide proper informed consent before procedures.
Informed consent is essentially a social contract between a surgeon and a patient. The surgeon is supposed to have a discussion with the patient about the benefits, risks and alternatives to the procedure so the patient can make an informed decision about whether to go through with the surgery. The conversation is what puts the "informed" in informed consent.
Let's say a pre-op nurse asks a patient to sign the consent form, but the patient says he was online the night before and read that impotence was a potential side effect of the radical prostate surgery he's scheduled to undergo, and wants to know how likely that outcome is for him. The nurse wants to keep the OR workflow going and therefore tells the patient to sign the form and that the surgeon will be in momentarily to answer his questions.
The nurse closes the chart and leaves to care for other patients. Moments later the anesthesiologist walks in and sees the signed form, so he pre-medicates the patient, who is now under the influence of a sedative. The surgeon comes in, and the anesthesiologist informs him that the consent form has been signed and the patient is ready for surgery. The patient is wheeled to the OR and the procedure is performed.
The patient now can sue for the lack of informed consent, saying he had questions and the surgery proceeded without his permission. The surgeon can be sued even if he didn't know the patient had questions. The nurse can be sued as well, which is something many nurses don't realize. In this case, the nurse intervened in the physician-patient relationship and prevented the surgeon from fulfilling the social contract with the patient. The nurse essentially became the physician by not allowing the patient an opportunity to get his questions answered.
Your facility could face legal action as well. Nurses can be contributorily negligent by bypassing policies and procedures. In this example, your facility likely has a policy that states no surgery can start unless the patient signs a consent form. Circulating nurses or other members of the operating room staff must make sure that happens, and, even though it sounds simple, it doesn't always get done. If the procedure takes place without a consent form being signed, your facility could now be found negligent. The physician can still be sued as well, but the damages would now be split between the surgeon and your facility.
