Home care continues to expand. With this growth are opportunities for registered dietitians (RDs) to demonstrate the vital role that they play not only in providing optimal nutrition care, but also in contributing to each patient's quality of life. Home care nutrition services range from individual patient counseling to managing and monitoring parenteral nutrition. RDs' knowledge of nutrition, reimbursement, and new technologies position them to improve care and control costs. Current roles and responsibilities along with emerging areas of professional growth give RDs a multitude of options to provide and expand their services and value in home care.
