Why is it important to detect Precursor Events in medical practice?
It is evident that if precursor events can be detected and timely action taken, more serious consequences can be prevented. Since Heinrich introduced the concept, many authorities have drawn attention to its importance – particularly in high stakes industries such as aviation, transport and nuclear. Witness the loss of the spacecraft Challenger due to an ‘O’ ring failure where the significance of multiple minor failures of this component in previous launches had gone unrecognised. Several instances of foreign runway objects causing damage to Concorde had been recorded prior to its total loss in July 2000. Yet in medical practice it is only in relatively recent years that the significance of precursors has been recognised and system changes introduced in, for example, specialties such as surgery and anaesthesia.
Is it easy to detect Precursor Events?
Theoretically, yes, but in practice much less so. There are multiple factors in play.
Examples of Precursor Events would include a wrong dose drawn up and administered but with no adverse consequences; or the mislabelling of the side or type of operation on an operating list but detected just in time. Often the only person in a position to recognise a low harm event is the person involved; if that person fails to appreciate its significance and report, the opportunity for pre-emptive action is lost. Factors mitigating against detecting and reporting precursor events include:
- Fear of retribution or personal consequences
- Failure to recognise a situation or event as a ‘Precursor’
- Lethargy and/or time constraints
- Bureaucracy
- Poor ‘Safety Culture’ in the workplace
An enquiry by the Kings Fund in 2016 described one of the problems well:
“People spoke of feeling embattled and isolated, working ‘in the implementation gap’ – and of the personal sense of shame when things go wrong. This in turn leads to self-silencing and a consequent lack of open conversation that could help to identify and tackle problems in the wider system. If one assumes that most care is characterised by complexity, then just focusing on individual behaviour is simplistic, unethical and part of the reason why there is an implementation gap in the first place.”
How does the CORESS address the ‘nervousness’ of reporting: The ‘Honest Broker’ approach?
Learning from Aviation that one of the most important barriers to reporting is fear of personal consequences – real or perceived – CORESS is designed as:
- An independent charity
- A confidential service
- A secure service
‘It was discovered some years ago, that professionals, even operating in a developed safety-confidential environment such as aviation, reported more readily and to a far greater degree to a third party that was clearly separate from employers or regulators.’
To achieve this CORESS has adapted the successful Confidential Human Factors Incident Reporting Programme (CHIRP): https://www.chirp.co.uk
