Given the prominence of Psychological Safety (PS), it’s worth sharing some research. It’s likely among the most studied modern concepts in organisational theory – so I can barely scratch the surface. Focus first is articles I’ve summarised, and then on any other full-text items I can find. In my haste, I’ve probably included some psychological… Continue reading Mini-Compendium: Psychological Safety
A perspective on applying Just Culture and Safety-II principles to improve learning from sentinel events in healthcare
This discussion paper from de Vos, Dekker and others discusses applying Just Culture and Safety-II to improving from healthcare sentinel events. I think it’s based on de Vos’s PhD. They start showing some evidence that among hospitals convinced that they have a “blame-free” culture also “reported that culpability was of primary concern in their investigations… Continue reading A perspective on applying Just Culture and Safety-II principles to improve learning from sentinel events in healthcare

Coffee drinking timing and mortality in US adults (** tl;dr: coffee is awesome)
This may interest people, exploring the role of coffee drinking on all-cause mortality and Cardiovascular disease (CVD). Large sample, but observational and via 7-day dietary record, with follow-up periods. Note: Normally we need to be cautious with study methods and limits, but since we’re dealing with coffee – I’ll accept no ill spoken. Coffee defies… Continue reading Coffee drinking timing and mortality in US adults (** tl;dr: coffee is awesome)
Identification of management traits related to human factors in new views of safety approaches
This paper from Leônidas Brasileiro and colleagues evaluated common attributes across approaches grouped under ‘New View’. i.e. HRO, S-II, SD, RE & HOP – they used both literature and Delphi method. Not a summary since you can read the full paper. It’s an accessible read if you’re keen to quickly understand some key differences and… Continue reading Identification of management traits related to human factors in new views of safety approaches

Was meant to be a mini-post. But, too many interesting statements. Extracts: · Eastman starts with “So you’ve come to Pittsburgh to study accidents, have you?” says the… Continue reading 1910 Pittsburgh Survey challenging worker ‘carelessness’ as main ’cause’ of accidents
Imbalanced sleep increases mortality risk by 14–34%: a meta-analysis
Poor sleep increases mortality risk by 14 – 34% according to a new meta-analysis. 79 cohort studies were included. Findings: · Inadequate sleep was defined as fewer than 7 h per night · 1/3 of adults regularly experience insufficient sleep which are “driven by lifestyle factors deeply rooted in modern society” · Chronic sleep deprivation has been linked… Continue reading Imbalanced sleep increases mortality risk by 14–34%: a meta-analysis
Human Error: Trick or Treat?
This 2007 chapter from Hollnagel unpacked whether we really need the concept of “human error” (HE). It’s a whole chapter, so I’ve skipped HEAPS. Tl;dr according to Hollnagel: · “there is no need of a theory of “human error” because the observed discrepancies in performance should be explained by a theory of normal performance rather… Continue reading Human Error: Trick or Treat?
1912 article discussing the role of fatigue in industrial accidents and arguing against ‘carelessness’ as an “ultimate cause”
This was an interesting article from 1912 highlighting the role that fatigue has in industrial accidents. Also challenges ‘carelessness’, saying it doesn’t account for the effects of fatigue. While scientific knowledge has progressed over the century, it’s cool how well they articulated the issue. · Image 1 top panel shows a breakdown of accidents per time… Continue reading 1912 article discussing the role of fatigue in industrial accidents and arguing against ‘carelessness’ as an “ultimate cause”
