BackgroundUnplanned extubations in PICU are used as a measure of quality in clinical governance strategies. While many factors, such as sedation or unit activity, impact negatively on unplanned extubations, high nurse-patient ratios reduce adverse patient events and improve patient safety. However, optimal nurse-patient ratios and the impact of the level of nursing expertise on the quality of care are unknown.AimThe study aimed to examine the impact of PICU nursing expertise on the unplanned extubations of children.DesignAudit and analysis of existing adverse event patient and nurse workforce data.MethodThis single-centre study examined unplanned extubations at a mixed general and cardiac tertiary PICU in the UK. Routinely collected data from nursing and adverse incident databases were examined. The dataset included over 74,477 nurse allocations between August 2006 and April 2011. Unplanned extubations were the adverse event of interest.ResultsA total of 78 unplanned extubations occurred between April 2006 and April 2011. The majority of unplanned extubations occurred when patients were looked after by junior nurses. The seniority of the nurse in-charge and the qualifications of the patient's nurse were not related to unplanned extubations. However, more unplanned extubations occurred at times of higher patient occupancy.ConclusionsNursing expertise and nurse-patient ratios were not related to unplanned extubations in this study. Further research is needed to explore the non-workforce factors such as the securing of endotracheal tubes, sedation levels and unit activity and their relationship with adverse events.Relevance To Clinical PracticeIn paediatric intensive care units where nurse-patient ratios are high, further investigation is needed to establish what impact non-workforce factors have on unplanned extubations.© 2015 British Association of Critical Care Nurses.
