"Each interruption was associated with a 12.1 per cent increase in procedural failures and a 12.7 per cent increase in clinical errors," the authors write. When nurses were not interrupted, procedural failure rates were 69.6 per cent and clinical error rates were 25.3 percent, compared with procedural failure rates of 84.6 per cent and clinical error rates of 38.9 per cent if they were interrupted three times.
In addition, errors became more severe as the number of interruptions increased. "Without interruption, the estimated risk of major error was 2.3 per cent; with four interruptions this risk doubled to 4.7 per cent," the authors write.
"The converging evidence of the high rate of interruptions occurring during medication preparation and administration adds impetus to the need to develop and implement strategies to improve communication practices and to reduce unnecessary interruptions within ward environments," the authors write. "While it is clear that some interruptions are central to providing safe care, there is a need to better understand the reasons for such high interruption rates."
Simple strategies to reduce interruptions could include easy access to whiteboards or other sources of information, along with having nurses wear vests with "do not interrupt" messages on them while conducting medication rounds, the authors note.
