Description of intervention(s) / exposure
A multimodal integrated system for the safe administration of drugs and compilation of an accurate automated record during anaesthesia
This System has now been used in 170,000 anaesthetics. It is multifaceted and includes novel equipment, consumables and procedures. It was designed on the basis of lessons from empirical incident reporting, the psychological mechanisms underlying human error and the principles of system safety developed in the high-risk chemical, nuclear and aviation industries. It includes specialised trays (which support aseptic technique and promote a well-organised anaesthetic workspace), colour- and bar-coded labelling of syringes (which facilitate the selection and tracking of drugs), pre-filled syringes for the most commonly used anaesthetic drugs (to remove a key error-prone step in drug administration and to save time), and automatic visual and auditory verification of syringes using a computer and bar-codes just prior to each drug administration. The System also compiles an automated anaesthetic record, with the intention of improving comprehensiveness and accuracy, and of freeing the anaesthetist to spend more time caring for and monitoring the patient.
The duration of the intervention will be up to 12 months in one or more designated operating rooms at Auckland City Hospital

Outcomes
Primary outcome [1] 3810 0
The composite of 1) rates of error related to iv drug administration; 2) failures in the accuracy and completeness of the anaesthetic iv drug records
Timepoint [1] 3810 0
The rates of drug administration errror will be assessed by obesrvaton and other techniques during each anaesthetic, over a period of up to 12 months in one or more designated operating rooms. Failures in the accuracy and completeness of anaesthetic records will be assessed weekly by reference to copies of the records.
Primary outcome [2] 3811 0
Failures in the accuracy and completeness of anaesthetic records
Timepoint [2] 3811 0
Assessed after each anaesthetic
Primary outcome [3] 240764 0
Lapses in vigilance tested with a vigilance
probe. To be reported as a co-primary outcome with outcome 1.
Timepoint [3] 240764 0
Lapses in vigilance will be assssed in real time using an automated vigilance probe during the study anaesthetics.
Secondary outcome [1] 6423 0
The difference between Maori and other groups of patients combined in the primary outcome variable
Timepoint [1] 6423 0
Ethnic data will be collected for all participating patients at the start of each anaesthetic
Secondary outcome [2] 6424 0
Rate of actual harm from error
