The ‘ironies of automation’ refers to a set of unintended consequences as a result of automation, that could detrimentally affect human performance on critical tasks. Automation might increase human performance issues, rather than eliminate them.
Measuring the workload that people experience is important, because subjective workload has an impact on human performance. A high workload eats into our limited mental resources and can lead to errors, near-misses and incidents. Workload is often measured by the resources available (such as nurse-to-patient staffing ratios), but workload is experienced differently by different people. For example, two nurses assigned to the same number of patients in the same Intensive Care Unit may experience workload differently due to the stability and complexity of their patients. Therefore, a subjective measure of workload can provide helpful insights beyond traditional measures such as staffing ratios. One of the most common measures of subjective workload developed by the NASA Human Performance Group is now available as an App and can be applied in any industry.

The NHS is not a single organisation – there are many parts that make up the NHS. However, these components do not operate as separate entities, they are interconnected and work together as a system. This creates challenges for those that lead these organisations. A recent report on leadership by The King’s Fund: “Leadership in today’s NHS: Delivering the impossible” questions whether senior leadership roles in the NHS are still “do-able”.

And this isn’t a reference to the Stephen King novel “Christine”, about a car apparently possessed by supernatural forces. This article examines how a technological change has led to tragedy. Please share this “safety moment” with family, friends and colleagues.
