Background and study aims
Delirium is a state of mental confusion that affects 30-40% of elderly people admitted to hospital. Studies have shown that one in four geriatric patients suffers from an episode of delirium at least once during their stay in the hospital. It is associated with poor outcomes at hospital discharge as the condition of delirium could persist for as long as 6 to 12 months after discharge, resulting in the need for rehabilitation services, nursing home placement or home care services. The Geriatric Monitoring Unit (GMU) is a specialised 5-bed unit for delirious patients, supported by 24-hour intensive nursing care. The GMU provides a controlled environment for the treatment of delirious patients. In this unit, the medical team is able to treat the delirious patients in an optimal environment where aggravating factors of delirium such as the use of physical constraint, medication, changes to surrounding environment and source of noise and distracters can be minimised or removed entirely. The aim of this study is to look at outcomes in patients with delirium who are admitted to the Geriatric Monitoring Unit (GMU), compared to usual clinical care in a general ward setting.
Who can participate?
Patients aged 65 and over with delirium
What does the study involve?
Participants are randomly allocated either to be admitted to GMU or to be put on a waiting list and receive the usual good care in the geriatric medicine department. The duration of delirium, length of hospital stay, rate of falls, types of injuries (if falls occur), reduction in use of physical restraints, medication use, urinary catheter use, pressure ulcers, infections, and family/caregiver satisfaction are all measured when the participants are followed up 6 and 12 months later.
What are the possible benefits and risks of participating?
The results of this study may help the healthcare system by improving patient safety, quality of care, and patient/family/caregiver satisfaction. There are no risks to participants as this is an observational study and no additional specific treatments are carried out.
Where is the study run from?
Tan Tock Seng Hospital (Singapore)
When is the study starting and how long is it expected to run for?
November 2010 to November 2011

| Scientific title | A new model of hospital care for frail elderly persons admitted to hospital with delirium |
| Study objectives | The trialists describe a new model of delirium care in the acute care setting, titled Geriatric Monitoring Unit (GMU) where the important concepts of delirium prevention and management are integrated. The primary aim of this study is to compare delirious patients admitted to the Geriatric Monitoring Unit (GMU), compared to usual geriatric care in general ward setting. The trialists postulate better outcomes in patients admitted to GMU versus usual geriatric care. The secondary aims include looking at which specific aspects of the interventions would yield the greatest benefit for future translation on a larger scale. The trialists hypothesize that patients with delirium admitted to the GMU will have better clinical outcomes with less need for physical and psychotropic restraints compared to usual care. |

| Health condition(s) or problem(s) studied | Delirium care in frail older persons admitted to the geriatric medicine department |
| Intervention | 1. The Geriatric Monitoring Unit (GMU) is a specialised 5 bedded unit which incorporates specific room design for an elder-friendly environment, lower staff-patient ratio, coupled with structured core, supported by 24-hour intensive nursing care 2. Multicomponent intervention and bright light therapy on sleep of these patients as well as the effect in antipsychotic and sedative-hypnotic use 3. The trialists wanted to study if patients with delirium admitted to GMU had better outcomes compared to those managed with usual care in the geriatric medicine department 4. The GMU consist of the interventions as listed above 5. The study consists of a pre/post GMU implementation as well as a concurrent GMU patients versus patients with delirium managed in the geriatric ward as controls |
| Intervention type | Other |
| Primary outcome measure | 1. Duration of delirium and severity of delirium 2. Use of physical and chemical restraints 3. Falls rate 4. Physical injury rate due to agitated behavior 5. Functional outcomes/gains in the elderly geriatric patients 6. Morbidity (such as nosocomial infection rate, urinary catheter use and catheter days, pressure ulcer rate) 7. Patient and family satisfaction score in elderly persons with delirium |
| Secondary outcome measures | 1. Looking at which specific aspects of the interventions would yield the greatest benefit for future translation on a larger scale 2. The effects of the multicomponent intervention and bright light therapy on sleep of these patients as well as their effect on antipsychotic and sedative hypnotic use |
