Clinical profile, outcomes and predictors of mortality in elderly patients admitted to the emergency medicine intensive care unit of a teaching hospital - A single-center registry.

Aim: Emergency intensive care of the elderly is often complicated and multifaceted. Understanding the clinical profile of elderly patients admitted in an emergency department-intensive care unit (ED-ICU) is crucial in planning health policies in geriatric emergency medicine. Thus, the aim of the study was to create a local registry of elderly people utilizing the ED-ICU services and to understand the rate and predictors of mortality.

Methods: A retrospective chart analysis was performed including all patients aged ≥60 years who had an ED-ICU admission during a 6-month period (August 2018-January 2019). A structured case record form was used to capture information such as basic demography, clinical profile, and outcomes.

Results: Total number of records considered for final analysis were 503. Mortality was seen in 21.07% (n = 106/503). The most common presenting complaint and cause of death was breathing difficulty (n = 48/503; 29.42%) and pneumonia (n = 41/106; 38.67%), repectively. The significant predictors of mortality [adjusted odds ratio; 95% confidence intervals; value] were hypertension (2.195; 1.255, 3.840; 0.006), chronic liver disease (CLD) (4.324; 1.170, 15.979; 0.028), malignancy (2.854; 1.045, 7.796; 0.041), requiring noninvasive ventilation (NIV) (2.618; 1.449, 4.730; 0.001), requiring intubation (6.638; 3.705, 11.894; <0.001), and requiring vasopressors (3.583; 1.985, 6.465; <0.001).

Conlusion: Approximately one in every five elderly patients getting admitted in ED-ICU died, and respiratory illness was the common diagnosis leading to death. Those with comorbidities such as hypertension, CLD, or malignancy and those requiring NIV, intubation, or vasopressors had higher mortality.
