Delirium in long-term care setting: indicator to severe morbidity

Area of Science:

• Gerontology
• Neurology
• Infectious Diseases

Background:

• Delirium is a common yet serious condition in elderly, functionally dependent long-term care (LTC) patients.
• Dementia and functional dependency are significant risk factors for delirium in this population.

Purpose of the Study:

• To determine the incidence of delirium in elderly, demented, and functionally dependent LTC patients.
• To identify predictors associated with delirium development, duration, and mortality.

Main Methods:

• Prospective data collection including demographic, clinical, functional, nutritional, and cognitive assessments.
• Utilized Confusion Assessment Method (CAM) and Delirium Rating Scale (DRS) for delirium detection.
• Analyzed blood counts and chemistry, alongside clinical observation.

Main Results:

• Delirium incidence was 34%, predominantly caused by infections (58%), metabolic abnormalities (36%), and adverse drug effects (18%).
• Independent predictors for delirium duration included low albumin, high comorbidity, male gender, advanced age, and cardiovascular disease (CVD).
• Mortality rate was 48%, with infection (70%) as the primary cause of death; predictors included infection, advanced age, low albumin, dehydration, and congestive heart failure (CHF).

Conclusions:

• Early recognition and management of underlying conditions are crucial for improving outcomes in LTC patients with delirium.
• Continuous monitoring of cognitive and functional status is vital for timely intervention.
• Infections pose a significant threat, necessitating prompt diagnosis and treatment.
