Litigation related to inadequate anaesthesia: An analysis of claims against the NHS in England 1995-2007

Abstract

Inadequate anaesthesia may cause distress to the patient and lead to medical litigation. All claims made to the NHS Litigation Authority 1995-2007 were obtained and the data was examined independently by all authors and classified. In a dataset of 1067 claims there were 161 cases of inadequate anaesthesia and data were suitable for analysis in 159: intra-operative awareness (79), brief awake paralysis (20) and inadequate regional anaesthesia (60). The total cost of closed claims was £3.2m. Cost was incurred in 100% of claims of brief awake paralysis, 87% of claims of awareness and 80% of claims of inadequate regional blockade. Mean cost of closed claims was £32 680 for anaesthetic awareness, £29 345 for inadequate regional blockade and £24 364 for brief awake paralysis. Inadequate anaesthesia accounts for 19% of anaesthesia-related claims in the NHS in England. Strategies that reduce anaesthetic awareness, drug errors and inadequate regional blockade are known and their improved implementation is likely to reduce such claims. © 2009 The Authors.
