“…Nurses use of the CAM-ICU improved organization of assessment (Scott et al, 2013) and improved patient outcomes (Oosterhouse et al, 2016). Use of the CAM-ICU also facilitated recognition of hypoactive delirium (Jung et al, 2013;Schaef, 2019) and distinguished between other causes of restlessness (Zamoscik (Bourbonnais et al, 2016); positive correlation between perceived importance and use (Hamdan, 2019) (−) physiological parameters interpreted as pain episode (Alikiaie et al, 2019;Gerber et al, 2015); prefers own clinical judgement (Deldar et al, 2018;Mascarenhas et al, 2018); does not believe result; belief that tool is not necessary if sedated/given analgesics; belief that unconscious patients feel no pain; unfamiliar with tool (Deldar et al, 2018); consider nurses' opinion as gold standard (Van Der Woude et al, 2016); used tool more in patients able to report than unable to report (Hamdan, 2019); knowledge of behaviors indicating pain was negatively correlated with perceived adequacy of departmental pain treatment (r = −0.19, p < 0.05) (Asman et al, 2019) Agitation (+) awareness of paradigm shift to "awake and comfortable" (Egerod et al, 2013); tool use balanced with other assessments (Hetland et al, 2018) Delirium (+) tool use increased awareness of delirium (Jung et al, 2013); tool use supplemented other assessments (LeBlanc et al, 2018); patient-centered care; perception of delirium as a problem (Özsaban & Acaroglu, 2016); retained knowledge after education intervention (Smith et al, 2017); understood how to use (Swan, 2014); belief that delirium is important to assess (Powell et al, 2019) (−) mechanically ventilated patients (Andrews et al, 2015;Özsaban & Acaroglu, 2016;Rowley-Conwy, 2017;Scott et al, 2013); prefers own clinical judgement (Christensen, 2014;Steinseth et al, 2018;Zamoscik et al, 2017); question accuracy ...…”
