Managing Type 1 diabetes can be challenging, as it requires a delicate balance of insulin to maintain blood glucose levels within a safe range. Many people with diabetes rely on insulin pumps to help with this task, but recent news from the US Food and Drug Administration (FDA) highlights the potential risks associated with technology.
The FDA issued a recall specifically targeting users of the Tandem t:slim X2 insulin pump and its companion iOS app. This app is designed to monitor and control the pump, which delivers a steady infusion of insulin throughout the day and bolus doses for meals. However, a software bug in version 2.7 of the mobile app can cause it to crash unexpectedly on iOS devices, leading to constant relaunching and draining the pump’s battery.
If the pump’s battery dies, insulin delivery stops, which can result in hyperglycemia or elevated blood sugar levels. If left untreated, hyperglycemia can progress to diabetic ketoacidosis, a serious condition that can lead to coma or death. While no serious injuries have been reported due to this bug, over 200 incidents have been documented by the FDA, prompting the recall.
The key takeaway from this incident is the importance of software design in critical systems. While automatically relaunching a crashed app may seem like a good idea, it can have unintended consequences in life-saving devices. A more prudent approach would be to implement a safe mode and alert the user of the issue, rather than risk battery depletion and potential harm.
This incident serves as a reminder of the need for thorough testing and accountability in the design of medical technology. By learning from past mistakes and prioritizing user safety, future incidents like this can be avoided.
