Study the effect of 6-weeks porcine protein supplementation vs isocaloric comparator (carbohydrate) on functional outcomes in post ICU-patients. Patients will be included at ICU discharge. Included patients will receive the supplements twice daily (morning and afternoon), starting at the first day at the general ward.
To the best of our knowledge, a study on protein supplementation in the post-ICU period to address its effect on functional outcomes is lacking.
Patients discharged from the Intensive Care Unit frequently suffer from Post Intensive Care Syndrome. This syndrome is characterized by muscle weakness and physical disabilities besides neurocognitive and psychological disturbances. Studies have shown that protein requirements in the post-ICU phase are often not met. Furthermore, protein supplementation in other patient groups have shown beneficial effects. However, a study on protein supplementation during the post-ICU period is lacking. This study aims to investigate the effect of protein supplementation on functional outcomes in post-ICU patients.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Porcine protein group | Experimental | The patients will receive protein supplements twice daily (2x22g) for a period of 6 weeks during breakfast and lunch. The supplement will be delivered in powdered form. |

| Between group difference in composite score over time. The composite score consists of handgrip strength, muscle strength leg, muscle strength arm and exercise capacity. | Between-group difference in physical function over time expressed as a composite score. The composite score consists of handgrip strength, muscle strength leg, muscle strength arm and exercise capacity. Handgrip strength will be measured with the Jamar dynamometer Muscle strength leg will be measured with the handheld dynamometer m. quadriceps fem. Muscle strength arm will be measured with the handheld dynamometer bicepss brachii Exercise capacity will be measured with the 6 minute walking distance test. Measured values will be compared to normative data. Calculated percentages will be added up and together form the composite score. | At hospital discharge, an average of 11 days |
