About

Delirium is an acute, fluctuating, transient, and usually reversible disorder of cognition and level of consciousness, with a high incidence in critical care units, especially in the elderly. Its occurrence leads to unfavorable outcomes such as increased length of stay, morbidity, functional and cognitive decline, increased mortality, and healthcare costs, in addition to being emotionally challenging for family members and caregivers. Although there are instruments and interventions for screening, prevention, and management, it remains underdiagnosed and undertreated. Among non-pharmacological interventions, the role of Occupational Therapy (OT) has been highlighted in the literature for promising results, such as reducing delirium incidence and duration, as well as improving functional outcomes at hospital discharge. OT protocols described in the literature vary in their frequency and intensity of care, as well as in the composition of their interventions. This research aims to test the hypothesis that a protocol composed of interventions based on meaningful occupations and personalized cognitive stimulation with patient-interest themes may reduce delirium incidence and improve occupational performance in elderly patients admitted to critical care units, compared to the standard protocol.

Full description

Engagement in meaningful occupations promotes health in various contexts and needs to be further investigated regarding its applicability in delirium prevention, associated with cognitive stimulation. Most protocols propose OT sessions twice daily, posing a challenge to their applicability in clinical practice. Therefore, there is also a need to study an intervention with lower frequency and greater feasibility.

In this way, the research will have as its primary objective to Evaluate the effect of a new OT protocol on delirium prevention and occupational performance in elderly patients admitted to critical care units, while the secondary objectives will be:

• Characterize care goals related to occupations according to their respective areas (self-care, productivity, or leisure), patient-defined satisfaction, and importance.
• Assess the impact of OT intervention on cognitive status.
• Identify possible adverse events related to OT intervention. The sample will consist of elderly patients, aged 65 years or older, admitted to the general ICU, and who are not intubated. The sample will be randomized, with patients in the control group receiving standard intervention, while those in the experimental group will receive standard intervention plus daily Occupational Therapy.

114 participants in 2 patient groups

Control Group - Standard Protocol

No Intervention group

Description:

* Early Mobilization Protocol performed by the physiotherapy team twice a day. Institutional protocol for mechanical restraint to prevent physical restriction. * Education for Family Members. * Family member/companion present 24 hours a day with authorized visits at least twice a day. * Minimum as possible sedation.

Intervention Group - Standard Protocol + Occupational Therapy

Experimental group

Description:

1. \*Occupational Engagement\*: the occupational therapist will encourage the patient's participation in meaningful activities. Adaptations and resources may be utilized to facilitate occupational performance. 2. \*Cognitive Activities\*: Individualized and personalized cognitive activities will be conducted, based on the patient's preferences. 3. \*Environmental Enrichment\*: Installation of a clock and calendar within the patient's visual range on the wall.
