Does delirium prevention reduce risk of in-patient falls among older adults? A systematic review and trial sequential meta-analysis.

OBJECTIVES: To determine whether delirium prevention interventions reduce the risk of falls among older hospitalised patients. METHODS: A systematic search of health-care databases was undertaken. Given the frequency of small sample sized trials, a trial sequential meta-analysis was conducted to present estimate summary effects to date. A Bayesian approach was used to estimate the posterior probability of the delirium prevention interventions reducing falls risk by various clinically relevant levels. RESULTS: Five randomised controlled trials were included in our final meta-analysis. There was a 43% reduction in the risk of falls among participants in the delirium prevention intervention arm, compared to the control; however, confidence intervals were wide (RE RR = 0.57, 95% CI 0.32; 1.00, p = 0.05). This result was found to be statistically significant, according to traditional significance levels (z > 1.96) and the more conservative trial sequential analysis monitoring boundaries. The posterior probabilities of the delirium prevention intervention reducing the risk of falls by 10%, 20% and 30% were 0.86, 0.63 and 0.29 respectively. CONCLUSIONS: The results of this systematic review and trial sequential meta-analysis suggest that delirium prevention trials may reduce the risk of in-hospital falls among older patients by 43%. However, despite significant risk reduction found upon meta-analysis, the variation among study populations and intervention components raised questions around its application in clinical practice. Further research is required to investigate what the necessary components of a multifactorial intervention are to reduce both delirium and fall incidence among older adult in-patients.

Increasing the profile of the care of the older person in the ED: a contemporary nursing challenge.

The numbers of frail older persons using emergency departments are already considerable and will continue to increase over time. There are a number of issues related to the assessment and care of older patients that are significantly different to other patient groups. The traditional emergency department (ED) model focusing on rapid triage, treatment and throughput does not meet the needs of many older patients, who have complex presentations, and require comprehensive assessment and referral. In response to this, there are already a number of appropriate and innovative approaches to the care of the older patient demonstrated in the literature. Nurses have a crucial role in contributing to these approaches and in raising the profile of quality care of the older person. Some specific areas that ED nurses can focus on include a more comprehensive approach to assessment and discharge planning, improved communication with the patient and their personal carers, attention to basic nursing care, and making the physical environment safer and less stressful for the older patient. While developing collaborations with their aged care nursing colleagues is important, emergency nurses need to view care of the older person as a central part of their own core business.
