Brief summary
The goal of this randomized-controlled trial (RCT) is to compare the effectiveness of the DREAMS-OT intervention with standard care in reducing post-Coronary Artery Bypass Graft (CABG) surgery delirium in patients undergoing CABG surgery. The aims of the study are: 1. To determine if early and intensive OT will lower the incidence of post-op delirium in CABG patients compared to standard are. 2. To determine the cost effectiveness of the DREAMS-OT intervention. The study team will compare intervention group and standard care group (control group) to see if there is a reduction in the incidence of delirium in patients 5 days post-CABG.
Interventions
Patients will receive the DREAMS-OT protocol 3 times per day, 20 minutes per therapy session. Intervention frequency will be confirmed with a feasibility trial. If not feasible to maintain 3 times per day, the intervention will still be maintained at the same intensity of 1 hour per day, with a graded approach.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Delirium | Day 1 of post-CABG (AM and PM), Day 2 of post-CABG (AM and PM), Day 3 of post-CABG (AM and PM), Day 4 of post-CABG (AM and PM), Day 5 of post-CABG (AM and PM); (+/- 1 day for last measurement) | Incidence of delirium from Day 1 to Day 5 post-CABG are measured using the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) assessment tool. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Length of Stay | 3-months post-CABG (+/- 1 month) | Length of stay in ICU and hospital in days |
| Duration of Delirium | Day 1 of post-CABG (AM and PM), Day 2 of post-CABG (AM and PM), Day 3 of post-CABG (AM and PM), Day 4 of post-CABG (AM and PM), Day 5 of post-CABG (AM and PM) | Duration of delirium in subgroup of participants who develop delirium |
| Sleep Quality | 2 weeks prior to operation (Baseline measurement, +/- 2 weeks), Day 1 of post-CABG, Day 2 of post-CABG (+/- 1 day), 3 months post-CABG for 3 consecutive days (+/- 1 month) | Sleep quality (Duration of Total Sleep, Light Sleep, Deep Sleep and Rapid Eye Movement (REM) Sleep in hours) as measured with Oura Ring, a wearable sleep tracking device |
| Functional Status | Day 5 of post-CABG (+/- 1 day) | Functional status measured using Acute Care Index of Function (ACIF). The score ranges from 0 - 176 (or 206 for wheelchair-bound participants), with higher scores indicating better functional performance. |
| Physical Status | Day 5 of post-CABG (+/- 1 day), 3 months post-CABG (+/- 1 month) | Physical status measured using Functional Independence Measure (FIM). The score ranges from 0 - 126, with higher scores indicating better physical status. |
| Cognitive status | 2 weeks prior to operation (Baseline measurement, +/- 2 weeks), Day 5 of post-CABG (+/- 1 day), 3 months post-CABG (+/- 1 month) | Cognitive status measurement using Montreal Cognitive Assessment (MoCA). The score ranges from 0 - 30, with higher scores indicating better cognitive status. |
| Psychological State | 2 weeks prior to operation (Baseline measurement, +/- 2 weeks), Day 5 of post-CABG (+/-1 day), 3 months post-CABG (+/- 1 month) | Psychological state measured using the Hospital Anxiety and Depression Scale (HADS). The score ranges from 0 - 21, with higher scores indicating worse psychological state. |
