Prognostic Value of a New Tool (the 3D/3D+) for Predicting 30-Day Mortality in Emergency Department Patients Aged 75 Years and Older

The 3D/3D+ multidimensional geriatric assessment tool provides an optimal model of emergency care for patients aged 75 and over who attend the Emergency Department (ED). The baseline, or static, component (3D) stratifies the degree of frailty prior to the acute illness, while the current, or dynamic, component (3D+) assesses the multidimensional impact caused by the acute illness and helps to guide the choice of care facility for patients upon their discharge from the ED. The objective of this study was to evaluate the prognostic value of the 3D/3D+ to predict short- and long-term adverse outcomes in ED patients aged 75 years and older. Multivariable logistic regression models were used to identify the predictors of mortality 30 days after 3D/3D+ assessment. Two hundred and seventy-eight patients (59.7% women) with a median age of 86 years (interquartile range: 83-90) were analyzed. According to the baseline component (3D), 83.1% (95% CI: 78.2-87.3) presented some degree of frailty. The current component (3D+) presented alterations in 60.1% (95% CI: 54.1-65.9). The choice of care facility at ED discharge indicated by the 3D/3D+ was considered appropriate in 96.4% (95% CI: 93.0-98.0). Thirty-day all-cause mortality was 19.4%. Delirium and functional decline were the dimensions on the 3D/3D+ that were independently associated with 30-day mortality. These two dimensions had an area under receiver operating characteristic of 0.80 (95% CI: 0.73-0.86) for predicting 30-day mortality. The 3D/3D+ tool enhances the provision of comprehensive care by ED professionals, guides them in the choice of patients' discharge destination, and has a prognostic validity that serves to establish future therapeutic objectives.

OBJECTIVE

Assess the 3D/3D+ rapid geriatric assessment tool for the early detection of frailty, its usefulness to identify the effects of the acute process on the functional, physical, cognitive and socioenvironmental dimensions, as well as the medications that may have triggered the patient's reason for visit. Finally, assess the usefulness of 3D/3D+ together with the clinical diagnosis to adequate care resource at discharge from the emergency department (ED).

METHOD

Retrospective observational cohort study. Patients ≥75 years old, with clinical complexity visited at the ED were included. Basal frailty status was assessed using 3D (basal component), and the multidimensional impact of the acute process using 3D+ (current component). The main dependent variable was adequacy of the care resource at ED discharge.

RESULTS

278 patients were included, mean age 86 years (interquartile range: 83-90), 59.7% were women. According to the basal component (3D), 83.1% (95%CI: 78.2-87.3) presented some degree of frailty. The current component (3D+) was altered in 60.1% (95%CI: 54.1-65.9). The adequacy of ED discharge was correct in 96.4% (95%CI: 93.0-98.0). One out of 4patients was admitted to a medicine ward.

CONCLUSIONS

3D/3D+ facilitates an optimal model of emergency care adapted to patients ≥ 75 years old treated in EDs. It stratifies the level of frailty (3D), detects the severity of patients' acute problems (3D+) and contributes to decision-making regarding the most appropriate care resource at ED discharge.
