Patient safety, human factors & CRM

Also known as Patient safety · Human factors · Crisis resource management · CRM · Surgical safety checklist · Never Events · Non-technical skills · Second victim

The patient safety science is the study of the harm and its prevention in the healthcare. The framework rests on the systems approach (the Swiss cheese model, the active and the latent failures), the human factors (the cognitive load, the fatigue, the environment, the equipment), the crisis resource management (the leadership, the communication, the situational awareness, the task management), the tools (the WHO surgical safety checklist, the time-out, the briefings and the debriefings), the non-technical skills (the ANTS), the critical incident analysis (the root cause, the learning), and the second-victim support. The anaesthetist is the leader in the perioperative safety.

Red flags

  • The most common anaesthetic errors are the systems errors (the wrong drug, the wrong concentration, the disconnect, the equipment failure), not the knowledge gaps. The prevention is the systems design (the standardisation, the checklists, the redundancy, the forcing functions), the CRM, and the culture — the naming-and-shaming of the individual is the wrong approach that suppresses the reporting and the learning.

The one-line answer

Most anaesthetic harm is a system failure, not a knowledge gap. The safety framework rests on Reason's person-versus-system distinction (errors as consequences of upstream conditions, not causes), human factors (workload, support, fatigue, cognitive load), crisis resource management (leadership, communication, situational awareness), and the tools that operationalise them — the WHO surgical safety checklist, the time-out, and the just culture that makes reporting safe.[9][2][3][10]

Meet the patient

A 4-year-old for bilateral myringotomies receives the wrong ear. The surgeon operated on the side marked on the whiteboard, not the side in the consent form. No time-out was done because the list was running late. The parents are distraught, the registrar is shattered, and the coroner will ask one question: why was the checklist skipped?[6]

This is a Never Event — wrong-site surgery — and it is the canonical systems failure. No single person made a single error. The defences (consent verification, site marking, time-out, team confirmation) all failed in sequence. The lesson is not who to blame — it is how the holes aligned.[6][7]
