MacGyverism and “hacking COVID-19”

COVID-19: Keeping the baby in the bath (Part 5)

First do no harm

Hippocrates AD 245

Necessity is a powerful driver of innovation. During the past few months we have all seen fast-paced change implementation – whether that be the creation of new clinical spaces for managing critically ill patients, the adoption of new processes of care such as airway management, or the use of new devices and technologies such as baby monitors to allow communication with patients and staff in isolation rooms. The ingenuity and adaptability shown by healthcare workers and health systems is truly remarkable.

Indeed, there are circumstances where radical innovation and rapid implementation is necessary to save lives. An example is improvised personal protective equipment (PPE) when there is literally no other option in a shortage. However, we have to be wary of the “MacGyver bias”, which is our tendency to hold home-made workarounds to a lesser evidence-based standard than commercially available devices (Duggan et al, 2019). Similarly, we need to be wary of “gizmo idolatry”, which is our implicit conviction that a more technological approach is intrinsically better than one that is less technological (Leff and Finucane, 2018). Of note, the standards required of devices, in general, are much lower than what is demanded of drug therapies prior to implementation in clinical practice (Thimbleby, 2013), although this has been vigorously critiqued as having more to do with market forces than patient safety.

Apparently benign technologies and interventions can lead to unintended consequences because healthcare is complex, dynamic, and interdependent (Carroll and Rudolph, 2006). Hence, we should rightly treat innovations – such as the aerosol box for intubation and shared ventilation strategies – with initial skepticism. They may yet prove to save lives, but the potential for harm for any new technology is often under-estimated and the burden of proof lies with those who claim they are beneficial. Most importantly these workarounds and “worst case scenario” solutions should never replace proper planning and provision of proven equipment. Too often, the opportunity costs of developing some new tool, rather than hiring more staff, are underestimated. Wherever possible, innovations – whether home-made or commercially available – should be rigorously tested before implementation into a specific clinical context. This last point is critical, as what works in one health care context may not work in another. 

So, how should we be testing and developing these new innovations? In many cases translational simulation is useful. Translational simulation is defined as healthcare simulation focused directly on improving patient care and healthcare systems, through diagnosing safety and performance issues and delivering simulation-based intervention, irrespective of the location, modality or content of the simulation (Brazil, 2017). The potential applications are diverse, and include in situ simulation to detect latent safety threats (Patterson et al, 2013), simulation-based clinical space testing (Colman, 2019), and integration of simulation with a design thinking approach (Petrosoniak et al, 2020). Some examples relevant to COVID-19 have already been published on litfl.com, including simulation to develop airway management strategies, testing of the aerosol box, and development and testing of an approach to shared ventilation. Of course, not everything needs to be simulated, and numerous other design and human factors/ ergonomics (HFE) methodologies can be applied to healthcare innovations. HFE approaches are especially useful because they are design-driven, take a systems approach, and focus on optimising both system performance and human well being (Dul et al, 2012). Unfortunately, capacity and expertise for translational simulation, human-centered design, and HFE has been under-developed in healthcare (Gurses et al, 2012; Bromiley, 2014) despite their apparent effectiveness (Mao et al, 2015; Xie and Caryon, 2015). The COVID-19 pandemic may yet demonstrate their importance to healthcare quality and safety. Indeed, some have argued that the future of critical care lies in quality and education (Niven et al, 2019).

Next, we will discuss Novel drug therapies and COVID-19 clinical trials.
