Evidence or Efficiency? How We Make IPC Decisions
from Infection Control Matters Hosted by Brett Mitchell
In this episode, Phil Russo and Brett Mitchell are joined by Dr Shalini Elangovan from Duke-NUS Medical School in Singapore to discuss her global study exploring how IPC professionals make decisions. Using a discrete choice experiment, Shalini and colleagues examined the trade-offs people make between clinical evidence, cost-effectiveness, implementation time and the additional workload an intervention creates. What actually makes an IPC professional say “yes” to an intervention? The study found that cost-effectiveness was the most important attribute overall, but also identified striking differences between “evidence seekers” and “efficiency seekers,” particularly between respondents from lower/middle- and high-income countries. This suggests that the setting in which you work may influence what you value when deciding whether an IPC intervention is worth implementing.
