研究概览
简要总结
This research study will be conducted in two parts. The first part will consist of selecting appropriate screening and assessment tools for Veterans undergoing elective surgery and identifying the number of Veterans who are malnourished and at risk of malnutrition. The second portion of the study will be to determine if a protein-enhanced diet before and after surgery will improve function and postoperative outcomes and compare the results to an education control group.
详细描述
In year 1 of the two-part research study, an observational, prospective study of 75 Veterans preparing for elective surgery will be conducted. The purpose of this study will be to select appropriate nutrition screening and assessment tools and to employ them to characterize malnutrition prevalence and severity and establish cut-off values associated with malnutrition in this population. In years 2-5 of the research two-part research study, a pilot randomized controlled trial will be conducted. The purpose of this study will be evaluate the feasibility, fidelity, and acceptability of a perioperative protein-enhanced intervention compared to an educational control. Veterans who are malnourished or at risk of being malnourished will be randomly assigned on a 1:1 ratio to either an education (nutritional counseling) control or high-protein perihabilitation arm. Participants in the high-protein perihabilitation arm will be provided with 30 grams of high quality protein supplements three times per day. The study will take place two weeks prior to an elective abdominal or GI surgery and will continue 4 weeks post surgery.

干预措施: Education Control (Other)
结局指标
主要结局
Determine Acceptability of Perioperative Protein-enhanced Intervention Compared to an Educational Control
时间窗: 30-day post-surgery follow-up (endpoint)
Satisfaction of overall participation in the research study (Likert Scale). I am glad I participated in this research study. 1 - Strongly Disagree and 5- Strongly Agree
Physical Function
时间窗: Baseline, day of surgery (an average of 12 days from baseline), 30-days post-surgery
Short physical performance battery - higher scores means a better physical performance (Total score = 0-12)
Evaluate the Feasibility of a Perioperative Protein-enhanced Intervention Compared to Control Arm.
时间窗: day of surgery (an average of 12 days from baseline [midpoint]) and 30-day post-surgery (endpoint)
Feasibility was measured as retention. Hypothesis was that 80% of the participants would be retained.
