Nurses have an important role in detecting, reporting, preventing and investigating medication errors. ‘However, nurses can also sometimes be responsible for making medication errors, so it is important that they understand the consequences of these mistakes…’1
All medication errors have consequences, be they major or minor. However, regardless of what the consequences might be there should always be a review, including the asking of questions. Below you will find a number of case studies, these are designed to explore medication errors you may have encountered and provide simple examples of some of the types of questions you should ask.
A patient receives a dose of 40 units of Humalog insulin instead of 40 units of Humalog Mix25. Humalog contains insulin lispro, a very short acting insulin. Humalog Mix25 contains insulin lispro 25% and insulin lispro protamine suspension (intermediate acting) 75%. A dose of 40 units of Humalog Mix25 contains 10 units of insulin lispro.
What’s wrong here? The patient has received 4 times the dose of the very short acting insulin.
A patient with a severe diabetic foot infection with marked necrosis is ordered piptaz2. The patient has a penicillin allergy. Piptaz contains piperacillin which is a penicillin. The patient receives the first dose of the medication and suffers an anaphylactic reaction.
When responding to a medication error, the first responsibility is to the patient. There needs to be appropriate treatment by members of the health team.
How do you incorporate the Australian Open Disclosure Framework in the process of documenting the event? Open disclosure is mandated in The National Safety and Quality Health Service Standards and is subject to accreditation.3 How is the information communicated to the patient and family?
Contemplate the reasons for each of the errors outlined in the two case studies above and suggest appropriate strategies. For example in case study one, the nurse did not know the difference between the insulins and therefore a specific education program is required. In case study two, the nurse did not check the patient’s allergies on the medication chart prior to administering piptaz. The prescribing doctor failed to check as well. The steps in such a checking procedure will need to be reviewed and specific education is required.
There may be a number of factors that could have contributed to these errors. Consider the reasons why the errors may have happened:
What strategies could be implemented to reduce the risk of these types of errors happening again?
The National Safety and Quality Health Service Standards include in their medication safety standard that ‘medication incidents are regularly monitored, reported and investigated’; and that ‘action is taken to reduce the risk of adverse medication events’4.
