Evaluating implementation of the emergency severity index in a Belgian hospital.

INTRODUCTIONnTriage aims to categorize patients based on their clinical need and the available departmental resources. To accomplish this goal, one needs to ensure that the implemented triage system is reliable and that staff use it correctly. Therefore this study assessed the ability of Belgium nurses to apply the Emergency Severity Index (ESI), version 4, to hypothetical case scenarios after an educational intervention.nnnMETHODSnAn ESI educational intervention was implemented in accordance with the ESI manual. Using paper case scenarios, nurses interrater agreement was assessed by comparing triage nurse ESI levels with the reference answers noted in the implementation manual. Interrater agreement was measured by the percentage of agreement and Cohens κ coefficient using different weighting schemes.nnnRESULTSnOverall, 77.5% of the scenario cases were coded according the ESI guidelines, resulting in a good interrater agreement (κ = 0.72, linear weighted κ = 0.84, quadratic weighted κ = 0.92, and triage-weighted scheme = 0.79). Interrater agreement varied when evaluating each ESI level separately. Undertriage was more common than overtriage. The highest misclassification range (37.8%) occurred in ESI level 2 scenarios, with 99.2% of the misclassifications being undertriaged.nnnDISCUSSIONnImplementation of the ESI into a novel setting guided by a locally developed training program resulted in suboptimal interrater agreement. Existing weighted κ schemes overestimated the interrater agreement between the triage nurse-assigned ESI level and the reference standard. By providing an aggregated measure of agreement, which allows partial agreement, clinically significant misclassification was masked by a misleading good interrater agreement.

Integrating and safeguarding care: The potential role of health information technologies:

The increasing burden of chronic diseases is one of the greatest challenges healthcare systems globally are facing. Across the world, compelling demands can be found for a fundamental shift in the organisation of health and social care to meet the needs of chronic patients. Integrated care has gathered momentum to overcome fragmentation of care in order to create care systems which are demand-driven, client-centred and cost-conscious. Health information technology – often referred to as eHealth – is usually considered to be an essential building brick of integrated care. Moreover, health information technology is said to hold potential for improving patient safety in chronic care settings. The current perspective paper explores the role of health information technology in integrating and safeguarding care. We argue that health information technology – which supports integrated care – may create optimal conditions to improve patient safety, but only when well-implemented, state-of-the-art technologies are used.
