12-hour Time Limited Feeding in Critical Care
Purpose
This study is being done to assess the feasibility and safety of a time-restricted 12-hour enteral feeding protocol (experimental group) in comparison to a standard-of-care, 24-hour enteral feeding protocol (control group) in critically ill patients. Investigators hope to gain knowledge about how these feeding schedules affect feeding tolerance, blood sugar control, and other factors affecting critically ill adult patients. - Investigators expect that the 12-hour feeding protocol will be tolerated similarly to the 24-hour feeding protocol and will not result in a greater number of adverse events related to feeding. - Investigators expect that the proportion of participants in both groups receiving at least 75% of their estimated nutrition needs will be similar.

Arm Groups
| Arm | Description | Assigned Intervention |
|---|---|---|
|
Active Comparator Continuous 24 hour feeding (CONT24). |
24 hour tube feeding is the standard of care. They will receive tube feeding continuously over 24 hours daily. |
|
|
Experimental 12-hour time-restricted feeding (TRF12) |
The 12-hour time-restricted feeding group will receive the same amount of nutrition in 12 hours as would be needed in 24 hours. The hourly feeding rate will double. |

Detailed Description
Investigators will test a 12-hour time-restricted feeding (TRF12) protocol in critically ill adults and compare this to a standard-of-care, 24-hour continuous feeding (CONT24) schedule. Time-restricted feeding (TRF) is form of intermittent fasting involving eating within a consistent, shortened period each day, following by fasting for at least 12 hours daily. TRF may improve glycemic control, blood pressure, and circadian rhythms in metabolism relative to feeding over a longer period. In critically ill patients, most facilities feed enterally over 24-hours which may exacerbate sleep disturbances and post-intensive care syndrome. In addition to safety and feasibility measures, this 10-day trial will gather preliminary data regarding how these feeding protocols each affect glycemic control, sleep, and long-term effects of critical care, such as delirium.
