184 Paying attention to the feasibility of daily delirium screening in an acute hospital setting

Abstract

Abstract Background Delirium is highly prevalent, yet two-thirds of cases remain undetected. Irish national guidance recommends daily delirium screening for all acute hospital in-patients at risk of delirium, including older patients. We conducted a series of stakeholder workshops to identify the screening tool considered most feasible for daily delirium screening by staff nurses in our hospital. Methods We identified four tools validated for daily delirium screening from the Scottish Intercollegiate Guidelines Network guidelines on ‘Risk Reduction and Management of Delirium’. These included the DOS-13 (Delirium Observation Screening Scale); RADAR (Recognising Acute Delirium As part of your Routine); mRASS (modified Richmond Agitation Screening Scale); and SQiD (Single Question in Delirium). Two workshops for local nursing delirium champions were held to discuss the feasibility of each of these instruments. Workshops commenced with teaching on delirium prevention, management and the rationale for daily screening. Factors relating to the time taken to conduct the assessment, training required, suitability for nursing staff use, diagnostic accuracy, and other issues relating to feasibility were explored. Results The RADAR was considered the instrument with the best balance between feasibility of implementation and diagnostic accuracy. The mRASS was preferred as the next best option, however there was concern that this instrument would require significantly more training. The DOS-13 was considered too time-consuming and too detailed, however it was proposed as a useful behavioural charting tool in patients with known delirium. Although the SQiD was considered the quickest test to conduct, it was felt that staff changeover would lead to reduced diagnostic accuracy. Conclusion RADAR was deemed the test of choice for daily delirium assessment in UHW acute wards. A delirium care bundle incorporating the RADAR was hence developed and training of staff has commenced. The next steps will be to evaluate its feasibility and efficacy in the real-world setting.
