AS10.3-4 | Communication, Medical Errors and Medication Errors in Anaesthesia — Summary & Reflection

KEY TAKEAWAYS

Communication failures contribute to over 70% of sentinel events in operating theatres; key failure modes are hierarchy-induced silence, faulty handovers, broken closed-loop communication, distraction during drug preparation, and ambiguous verbal orders. Structured tools — SBAR, closed-loop read-back, two-challenge rule, crew resource management, and the WHO Surgical Safety Checklist — address each failure mode systematically. Medical errors are defined as failures of execution or planning (Institute of Medicine, 1999) and are classified as active (sharp-end, direct caregiver) or latent (blunt-end, systemic). The Swiss Cheese Model (Reason, 1990) explains how harm results from aligned holes in multiple defensive layers. Medication errors in anaesthesia are classified by type: wrong drug (commonest, including LASA swaps), wrong dose (including decimal-point errors), wrong route, wrong patient, wrong time, and wrong concentration. Anaesthesia-specific risk factors include the prescriber-dispenser-administrator concentration in one person, look-alike ampoules, LASA drug names, and production pressure. Prevention operates at system level (standardised colour-coded labelling per ISO 26825, physical separation of LASA drugs, smart infusion pumps with DERS, pharmacy pre-drawn syringes, tall-man lettering) and individual level (read-label three times, label immediately, verbal read-back, independent double-check for high-risk drugs, near-miss reporting). A just culture — non-punitive accountability for honest errors — is the institutional prerequisite for near-miss reporting and organisational safety learning.

REFLECT

Think about the last time you observed a drug being drawn up or administered in a clinical setting. Was the label verified before administration? Was there a verbal read-back of the drug and dose? Was a near miss ever reported from that ward or theatre — and if so, what changed as a result? If you were appointed as the patient-safety officer for your institution's anaesthetic department for one week, identify two specific medication-safety interventions you would prioritise based on what you observed, and explain which level of the Swiss Cheese Model each intervention targets.
