Anaesthetic records: an evaluation of variation across England.

We collected blank non-specialist anaesthetic records from 71 National Health Service Trusts in England. A data set was established by collating all data items found in an initial tranche of 28 records. All 71 records were subsequently analysed for each data item in this data set. We found significant variation: the most populated record included 216 data items and the least included 38 data items: a greater than five-fold variation. There was significant variation in the inclusion of data items commonly considered important to patient safety; 42% of records omitted documentation of fasting status, 72% omitted documentation of a discussion around the risk of accidental awareness during general anaesthesia, 92% omitted documentation of quantitative neuromuscular blockade monitoring and 63% omitted documentation for 'Stop Before You Block' when performing regional anaesthesia. The study highlights significant variability in the composition of anaesthetic records across England which may impact on its value as a data repository, an action trigger, a medicolegal account, and a tool to facilitate safe handover. Standardisation of the anaesthetic record or the establishment of standards of recording would help to allay potential risks to patient safety and assist in guiding future procurement of electronic solutions for anaesthetic records.
