Combining Nutrition Supplementation With an Exercise Program in Elderly Malnourished Frail Patients After Hospital Stay

Adherence to the combined exercise program with the oral nutrition supplement: Self-admistered questionnaire

Subjects will use a self-admistered questionnaire in paper pencil form consisting of the combined vivifrail passport checklist (provided by the vivifrail program, asking if the exersise program was performed or not and a 3-point likert scale question: "How demanding were the exercises for you?" with the answer options very demanding, moderately demanding and not very demanding) and a oral nutrition checklist (asking if the oral supplementation was consumed or not) to keep record of completed exercise sessions as well as the effort perceived during the activities and the daily intake of the oral nutritional supplementation. Higher scores of absolved exercise sessions with the intake of the oral nutrition mean a better outcome.

Time frame: The questionnaire is completed daily from the first day after hospital discharge until the last day of the 12-week intervention (84 days).

Inhibiting factors to follow the combined exercise and nutritional program: Semi-structured phone call interview using a self developed questionnaire

The semi-structured phone interviews have the purpose to shed light on the difficulties participants encountered while following the intervention. The self developed questionnaire (adapted from Hoogland J et al. 2019) uses a semi-structured approach and consists of 10 questions: Have you forgotten to consume ONS in the last 7 days? What is the usual dose per day you have taken in the last 7 days? When do you consume the drinkable food? How and when do you usually consume the ONS? Have you forgotten to exercise in the last 7 days? Did you complete the entire exercise session, or did you skip some exercises? What were the reasons that made it difficult to start or finish an exercise session in the last 7 days? How many minutes did it take to do the exercises per day? Do you feel stronger now than before you started the exercise and nutrition program? Do you feel less likely to fall now than before you started the exercise and nutrition program?

Time frame: 1 week after the initiation of the program (first day after hospital discharge plus 7 days)
