Part of an Award-Winning Presentation

The educational content in this course is presented by GrassrootsHealth Nutrient Research Institute in collaboration with Beth S. Sanford, DNP, MSN-Ed, RN, ACN, CLC, and the NDNA and NDAND. Course content was reviewed and approved by senior vitamin D researchers and scientists.

The course was developed as part of Dr. Sanford’s Doctor of Nursing Practice (DNP) doctoral translational research project to implement vitamin D research findings into public health and practice. Preliminary results of the project were disseminated at the 2022, Fifteenth National Doctors of Nursing Practice Conference in Tampa, FL, “Collaborating to Improve Healthcare Outcomes.” Results found that completion of a vitamin D toolkit, which included this e-course, a translational model, e-tools, and key resources (such as those found in the included Toolkit) significantly increased knowledge, confidence, and translation to practice and sphere of influence among nurses and dietitians.

Final results of this project were disseminated at the Health Professions Collaboration Conference: “Bridging Research with Practice,” hosted by the North Dakota Nurses Association, where the project won the award for Best Poster Presentation.
