Background: Hereditary Fructose Intolerance (HFI) is an inborn error of metabolism which results in the absence of an effective Aldolase B enzyme. Without this enzyme, ingestion of fructose and metabolic precursors leads to acute illness, multiorgan damage, and possible death. The increased presence of these sugars results in earlier onset of symptoms and more difficulty for those with HFI.

Purpose: The project’s aim is to increase awareness of HFI in healthcare providers using a learning module and assessments of knowledge at three different points in time.

Methods: The IOWA model for evidence-based practice projects was applied during the development and completion of this project. A learning module was used, and knowledge was assessed before, after, and one month after following completion of the module.

Results: Self-reported awareness of HFI increased on a 4-point Likert Scale from 1.6 to 3.06 from preassessment to post-assessment and from 1.5 to 2.8 for awareness of FM. The average amount of symptoms identified as being related to HFI increased from 1.95 to 3.76 (preassessment and post-assessment). Choice of genetic testing increased from 31.3% of participants to 90% in the post-assessment. The selection of dangerous diagnostic tests (IV fructose challenge and hydrogen breath test) decreased from preassessment (24.4% and 35.6%) to post-assessment (23.3% and 16.7%).

Discussion:Education focused on HFI had a significant impact on participants’ knowledge base as seen by the pre and post-test responses. As this project was conducted during the COVID-19 pandemic, significant attrition from the post-evaluation to the follow-up assessment was seen. Therefore, it is unclear whether the knowledge would be sustained over time. Future reiterations of this project should consider the requirements of all completion of the module within a specified timeframe and should include follow-up post-assessment items.
