Background Few studies have investigated delirium in a respiratory intensive care unit
(RICU) population, thus knowledge is limited regarding it. Aim, the present study aimed to
investigate the effectiveness of application of multicomponent nursing intervention to
controlling delirium among critically ill older adult patients. Quasi-experimental research
design was carried out to meet the aim of this study. A purposive sample included 60 old age
critically ill patients taken from respiratory intensive care in Aswan University Hospital. Tool
1, Patient assessment sheet was used for collecting data, which included two parts: bio
demographic data and medical data, Tool2, intensive care delirium screening checklist to
detection and monitoring delirium include eight screening area Each feature that manifests are
given one point and zero point if not manifests Ascore ≥ 4 indicated delirium.Tool3, Richmond
Agitation Sedation Scale (RASS) to predicted type of delirium. Tool4 Multiple nursing
intervention for controlling delirium. Results: Delirium was frequent in patients in the
standard care group compared with our intervention group (p = 0.04), however no substantial
differences between both groups regarding types, duration or delirium severity (P≥ 0.05),
respectively. Moreover, the duration of ICU stay was lowered in our intervention group (P=
0.001). Age was a substantial risk element for delirium development by multiple regression
analysis. Conclusion: the delirium episodes during RICU stay were established to all critically
older adults with respiratory illnesses, as anticipated, after application of a multicomponent
nursing intervention, the incidence of these adverse consequences was reduced.
Recommendation: replication of these study on the large sample size in other ICU that
provide care for critically ill older adult patients to decrease incidence of delirium within
critical care setting.
