Limited research exists on the impact of nutrition guidelines on clinical practice and patient health outcomes. This study investigated the effects of guideline training on implementing the diabetes prevention EBNPG and its relationship with health outcomes in prediabetes patients. Improved guideline congruence was observed after training, but it did not significantly impact related health outcomes. Further research is needed to explore the impact of evidence-based guidelines across different practice areas.
Limited research exists to evaluate nutrition guideline impact on clinical practice and patient health outcomes. In this study we investigate (1) the impact of guideline training on the implementation of the diabetes prevention Evidence-Based Nutrition Practice Guideline (EBNPG), and (2) the relationship between EBNPG congruence and resulting health outcomes in patients with prediabetes. We conducted an implementation study in which registered dietitian nutritionists (RDNs) provided nutrition care with 3-month follow-up to 102 pre-diabetes patients before and after a professional training on the implementation of the Diabetes Prevention EBNPG. Using the RDNs' Nutrition Care Process (NCP) documentation, we measured percent guideline congruence and health outcomes (body weight, waist circumference, fasting glucose, glycosylated hemoglobin), and modeled health outcomes. Guideline congruence improved after training by 4.3% (P < 0.05). However, no significant associations were observed between guideline training, or guideline congruence and health outcomes. Our model showed a reduction in waist circumference (2.1 +/- 0.92 cm; P = 0.023), and body weight (-1.78 +/- 0.55 kg; P = 0.001) throughout the course of the study. Training of nutrition professionals improved congruence to EBNPG for Diabetes Prevention. Nevertheless, improved guideline congruence did not impact related health outcomes. Standard care including nutrition intervention resulted in body weight and waist circumference reductions. Future research needs to further address the impact of evidence-based guidelines on outcomes in all areas of practice.
