Background: During a woman's pregnant state, a diet that is adequate in nutrition is critical to the developing fetus, especially in the lower socioeconomic status population. The healthcare provider is charged with the acute fundamental awareness of this additional factor that can grossly impact pregnancy. Nutritional advice from the health care provider is one of many key points that contribute to the successful outcome of the pregnancy. Purpose: The purpose of this quality improvement project was to develop a standardized, evidence-based practice (EBP) protocol for the management of maternal nutrition, gestational weight gain, and physical activity for provider use at an LSE community clinic. Theoretical Framework: Theory of Planned Behavior Methods: After receiving institutional support for the implementation of the protocol presentation and instruction of the Maternal Nutrition Guideline, pre- and post-surveys were administered to eligible participants. A quantitative descriptive design was used for the project. Results: There were twenty-six respondents for both the pre-and post-survey. The data analysis revealed that two questions revealed the most significant increase between the pre-and post-survey occasions utilizing the Mann-Whitney test and related to physical activity during pregnancy and dietary intake. An independent sample t-test was performed to compare the two occasions. There was a tendency for an increase in the the total score between the pre-and post-surveys, but the difference did not reach statistical significance, which may be related to sample size (t24df = 1.782, p =0.087). Conclusion: A standardized, evidence-based nutritional guideline is a necessary tool to serve as a consistent resource and empower all health care providers to bring awareness and understanding to facilitate positive outcomes to the obstetric patient population for which they care.
