Introduction:
Medical devices are an essential tool in the healthcare industry, but their safety and effectiveness rely heavily on the proper use of the equipment. Medical device user errors are a common issue faced by the industry, and it is crucial to address them to minimize patient harm. In this discussion, we will explore some of the methods and approaches used to identify the root cause of medical device errors, compare and contrast different types of equipment, and discuss incident investigation procedures.

1. Do you have any experience using the Root Cause Analysis (RCA) methodology to identify the actual causes of a problem?
As a medical professor, I have had the opportunity to teach RCA methodology to my medical college students. However, I do not have personal experience with using RCA to identify the actual causes of a problem in the medical device industry.

A BMET centered storyline that aligns with the RCA methodology could involve a faulty infusion pump. The sequence of events might include the user (nurse) reporting that the pump does not deliver medication properly. The equipment is inspected, and no mechanical defects are found, indicating that the problem is user error. The RCA process involves interviewing the nurse and other staff involved in the medication administration process to identify the root cause of the issue. The investigation reveals that the nurse did not receive proper training on how to use the infusion pump, resulting in incorrect medication delivery. Corrective actions would involve providing additional training to the staff using the infusion pump.

2. Compare and contrast 2 pieces of equipment (any type); one that is a ‘Good’ example of a simple user interface and one that is ‘Bad’, aka overly complicated.

One example of a good equipment design is the pulse oximeter, which measures the oxygen saturation levels in a patient’s blood. It has a simple user interface with intuitive buttons and clear visual indicators, making it easy to use. On the other hand, an example of bad equipment design is the dialysis machine, which has a complicated interface with many buttons and displays, making it harder for the user to operate.

3. If you were called to a medical ward to perform an Incident Investigation, what are some questions you might ask the user(s)?
During an incident investigation, some questions that I might ask the user(s) include:

– What were you trying to accomplish with the equipment?
– What steps did you take to operate the equipment?
– Did you receive any training on how to use the equipment?
– Did you notice any warnings, alerts, or error messages during the equipment operation?
– Did you report the incident to a supervisor or other staff member?
– Did you take any pictures, videos, or other documentation of the incident?

To verify that the user(s) were using the equipment correctly, I would review their training records, observe their equipment operation, and check the equipment logs for any errors or issues. If corrective user training is needed, the responsibility would fall on the hospital or medical facility to ensure that training is effectively accomplished.
