What would you do?

You've just started working on a new unit. During a busy day shift, you accidentally give medication to the wrong patient. You’re horrified, and are sure you did the necessary safety checks before administering the medication. On review, you realize two patients on the unit share a last name, and you mixed them up.

You monitor the patient closely. There are no immediate adverse effects. Since the patient seems unharmed, you wonder if the health care team, or the patient and their family, need to be informed.

What do you do next?

The following scenario demonstrates your accountabilities when you make a mistake in practice.

Pat, a newly registered RN, recently started working in a stroke rehabilitation unit. During a busy day shift, Pat accidentally gives amitriptyline to the wrong patient. Once Pat realizes her mistake, she’s horrified. She knows she did the necessary safety checks before administering the medication. On review, she realizes that the patient shares a last name with another patient on the unit, and she mixed up the patients.

Pat monitors the patient closely. There are no immediate adverse effects. Since the patient seems unharmed, Pat wonders if the health care team, or the patient and their family, need to be informed. She’s embarrassed about her mistake and doesn’t want to tell anyone. She’s unsure what to do next.

A commitment to her patient

Pat considers all the ways her mistake could affect the patient. She continues to closely monitor the patient for adverse effects.

She also thinks about her therapeutic relationship with the patient. Pat knows that trust is at the core of a therapeutic relationship, and that lying or omitting important information can irreparably damage that relationship. Pat realizes that in order to maintain the therapeutic relationship, she must be honest with the patient and include them as partners in their care.

Pat knows that she must always put patients first. She realizes that keeping her mistake secret in order to protect her professional reputation would be putting her own needs before the needs of her patient.

A commitment to creating a quality practice setting

Pat also reflects on why she made the mistake and the factors that led her to mix up the patients. If she made this mistake, it’s possible other members of the health care team might as well. Pat realizes that in order to prevent a similar error from happening again, she needs to speak up. She can advocate for her patients and provide them with the best possible care by making sure no one else makes a similar mistake.

A decision is made

Pat tells her charge nurse about the mistake. Together, they discuss ways to prevent someone else on the health care team from making a similar mistake. Pat also tells her charge nurse that she has never had to disclose a mistake to a patient before. Pat realizes this is a learning need and asks for her charge nurse’s help. Together, they discuss the best way to inform the patient.

After disclosing the error to the patient, Pat reflects on the day’s events and her role in them. She knows the error is an opportunity to learn. She thinks about her strengths, opportunities for improvement and key learning needs.

Putting patients first

When Pat disclosed her mistake to the team, she made the right choice to put her patient’s needs ahead of her own. She was also advocating for a quality practice setting and ensuring that future patients will receive safe care. By speaking up and putting her patient first, Pat was upholding the principles in the nurses’ Code of Conduct and meeting her accountabilities outlined in the Professional Standards, Revised 2002 and Medication practice standards. She was also meeting her professional duty to report any error, behaviour, conduct or system issue that affects patient safety.

About CNO

The College of Nurses of Ontario (CNO) is the regulator of the nursing profession in Ontario. It is not a school or a nursing association. CNO acts in the public interest by:

  • assessing qualifications and registering individuals who want to practice nursing in Ontario.
  • setting the practice standards of the profession that nurses in Ontario are expected to meet.
  • promoting nurses' continuing competence through a quality assurance program.
  • holding nurses accountable to those standards by addressing complaints or reports about nursing care.

The College was founded in 1963. By establishing the College, the Ontario government was acknowledging that the nursing profession had the ability to govern itself and put the public's well-being ahead of professional interests.

For the latest information, please see our Nursing Statistics page.

Anyone who wants to use a nursing-related title — Registered Nurse (RN), Registered Practical Nurse (RPN) or Nurse Practitioner (NP) must become a member of CNO.

Frequently Asked Questions

Go to the public Register, Find a Nurse, to conduct a search for the nurse. Contact us if you can't find the person you are looking for.

All public information available about nurses is posted in the public Register, Find a Nurse, which contains profiles of every nurse in Ontario. Publicly available information about nurses include their registration history, business address, and information related to pending disciplinary hearings or past findings.

Unregistered practitioners are people who are seeking employment in nursing or holding themselves out as being able to practice nursing in Ontario, but who are not qualified to do so. They are not registered members of CNO. Only people registered with CNO can use nursing-related titles or perform certain procedures that could cause harm if carried out by a non-registered health professional. CNO takes the issue of unregistered practitioners seriously. See Unregistered Practitioners for more information.

To ensure procedural fairness for both the patient (or client) and the nurse, the Regulated Health Professions Act requires that information gathered during an investigation remain confidential until the matter is referred to the Discipline Committee or Fitness to Practise Committee. CNO will not disclose any information that could identify patients (or clients) or compromise an investigation. See Investigations: A Process Guide for more information.

Information obtained during an investigation will become public if the matter is referred to a disciplinary hearing. If a complaint is not referred to a hearing, no information will be available publicly.

See CNO's hearings schedule, which is updated as hearing dates are confirmed. Hearings at CNO are open to the public and the media. For details on how to attend a hearing, contact the Hearings Administration Team.

A summary of allegations and the disciplinary panel outcomes can be found on the public Register, Find a Nurse. Full decisions and reasons are also available.

Where a disciplinary panel makes a finding of professional misconduct, they have the authority to reprimand a nurse, and suspend or revoke a nurse's registration. Terms, conditions and limitations can also be imposed on a nurse's registration, which restricts their practice for a set period. Nurses can also be required to complete remedial activities, such as reviewing CNO documents and meeting with an expert, before returning to practice.
