Older trauma patients are at high risk of delirium, especially those with underlying dementia or baseline frailty

Background Given the increasing numbers of older patients presenting with trauma, and the potential influence of delirium on outcomes, we sought to investigate the proportion of such patients who were diagnosed with delirium during their stay—and patient factors associated therewith—and the potential associations between delirium and hospital length of stay (LOS). We hypothesized that delirium would be common, associated with certain patient characteristics, and associated with long hospital LOS (highest quartile).Methods We conducted a retrospective observational cohort study of all trauma patients aged ≥65 years presenting in September to October 2019, interrogating medical records and the institutional trauma database. The primary outcome measure was occurrence of delirium.Results Among 99 eligible patients, delirium was common, documented in 23% (23 of 99). On multivariable analysis, adjusting for age, frailty and history of dementia, frailty (OR 4.09, 95% CI 1.08 to 15.53, p=0.04) and dementia (OR 5.23, 95% CI 1.38 to 19.90, p=0.02) were independently associated with likelihood of delirium. Standardized assessment tools were underused, with only 34% (34 of 99) screened within 4 hours of arrival. On univariate logistic regression analysis, having an episode of delirium was associated with long LOS (highest quartile), OR of 5.29 (95% CI 1.92 to 14.56, p<0.001). In the final multivariable model, adjusting for any (non-delirium) in-hospital complication, delirium was independently associated with long LOS (≥16 days; OR 4.81, p=0.005).Discussion In this study, delirium was common. History of dementia and baseline frailty were associated with increased risk. Delirium was independently associated with long LOS. However, many patients did not undergo standardized screening at admission. Early identification and targeted management of older patients at risk of delirium may reduce incidence and improve care of this vulnerable cohort. These data are hypothesis generating, but support the need for initiatives which improve delirium care, acknowledging the complex interplay between frailty and other geriatric syndromes in the older trauma patients.Level of evidence III

The Prevent Alcohol and Risk-Related Trauma in Youth (P.A.R.T.Y) program : an interactive injury prevention initiative in South-Western Sydney

Background: The Prevent Alcohol and Risk Related Trauma in Youth (P.A.R.T.Y) program is an interactive injury prevention intervention, specifically designed for “at risk” youths aged 15 to 19 years. Emerging evidence has highlighted its positive impact on altering student attitudes towards risk-taking behaviour across several Australian and international settings. This study aims to describe the risk-taking behaviours of youths in South-Western and Greater Western Sydney, and assess the effectiveness of the Liverpool P.A.R.T.Y program to alter attitudes towards risk-taking. Methods: From 2015 to 2020, schools and youth organisations across South-Western and Greater Western Sydney were invited to participate in the Liverpool Hospital P.A.R.T.Y program. Youths aged 15 to 19 years were selected to attend by their respective teachers based on eligibility criteria. Knowledge and attitudes towards risk-taking behaviours were measured using surveys across three time points (pre-program, immediately post-program, 3-to-6 months post-program). Results: A total of 2544 participants from 50 schools and youth organisations attended the Liverpool Hospital P.A.R.T.Y program. There were 130 participants who did not record a response to a single question across all three time points and were omitted from analysis. Of the remaining 2414 participants, 49% were male, and 41% had access to a provisional driver's license or learner's permit. There were significant changes in knowledge and attitudes to risk-taking behaviours from pre-to immediately-post-program. A separate analysis across all three time points was conducted in response to a poor 3-to-6-month follow-up rate (25%). There was decay in improvements across all six questions, with the largest change seen in perceived likelihood of injury when engaging in physically risk-taking activities (52.2% to 36.9%, OR 0.44, 95% CI 0.33 – 0.60, p < 0.001). Conclusion: This study demonstrated significant changes in participant attitudes towards risk-taking behaviours and their consequences, immediately after participating in the Liverpool Hospital P.A.R.T.Y program. However, the poor response rates at later follow-up highlight the need for ongoing engagement of the South-Western and Greater Western Sydney youths, to ensure these improvements are sustained

Frailty among older surgical patients and risk of hospital acquired adverse events : the South-Western Sydney frailty and nurse sensitive indicators study

Background: While advances in healthcare mean people are living longer, increasing frailty is a potential consequence of this. The relationship between frailty among older surgical patients and hospital acquired adverse events has not been extensively explored. We sought to describe the relationship between increasing frailty among older surgical patients and the risk of hospital acquired adverse events. Methods: We included consecutive surgical admissions among patients aged 70 years or more across the SWSLHD between January 2010 and December 2020. This study used routinely collected ICD-10-AM data, obtained from the government maintained Admitted Patient Data Collection. The relationships between cumulative frailty deficit items and risk of hospital acquired adverse events were assessed using Poisson regression modelling. This study followed the RECORD/STROBE guidelines. Results: During the study period, 44,721 (57% women) older adults were admitted, and 41% (25,306) were planned surgical admissions. The risk of all adverse events increased with increasing number of frailty deficit items, the highest deficit items group (4–12 deficit items) compared with the lowest deficit items group (0 or 1 deficit item): falls adjusted rate ratio (adj RR) = 15.3, (95% confidence interval (CI) 12.1, 19.42); pressure injury adj RR = 21.3 (95% CI 12.53, 36.16); delirium adj RR = 40.9 (95% CI 31.21, 53.55); pneumonia adj RR = 16.5 (95% CI 12.74, 21.27); thromboembolism adj RR = 17.3 (95% CI 4.4, 11.92); and hospital mortality adj RR = 6.2 (95% CI 5.18, 7.37). Conclusion: The increase in number of cumulative frailty deficit items among older surgical patients was associated with a higher risk of adverse hospital events. The link offers an opportunity to clinical nursing professionals in the surgical setting, to develop and implement targeted models of care and ensure the best outcomes for frail older adults and their families
