Title: The Effects of a Diabetes Education Program among African American (AA) adults to Improve Medication Adherence and Decrease Hemoglobin A1c (HbA1c).

Purpose: To evaluate the effects of a diabetes education program to decrease HbA1c and improve medication adherence in AA with diabetes in a Primary Care setting.

Method: This a quality improvement study and a descriptive quantitative design with a convenience sampling of 21 participants. Eligibility includes AA, ages 18 to 65, diagnosed with type 2 diabetes, and who attended routine care at project site. The results of pretest and posttest, and pre and post HbA1c were analyzed using Descriptive Statistics and Paired Sample T-test. The HbA1c was analyzed at baseline and three months after intervention. Five research engines were used to locate articles dated 2007-2017, with key articles obtained from CINAHL, PsycINFO, Nursing & Allied Health, Medline, and PubMed Clinical Queries.

Results: A total of 21 participants enrolled in the study. Out of 21 participants, 11 returned for post HbA1c recheck. The analysis revealed statistical significant difference between the pre and post test scores, (M =66.43, SD = 11.634) from the post test score (M = 93.81, SD = 9.862), t (21) = -9.580, p < .0005 (two tailed). The mean increase in post test scores was -27.136 with 95% confidence interval ranging from -33.343 to -21.419. Whereas the difference between the pre-HbA1c and post HbA1c mean was statistically insignificant, there was an observable clinical significance in patients’ outcome.

Conclusion: The findings revealed significant improvement in diabetes knowledge and no statistical significance in the HbA1c results. Future research is needed with a large sample size over a longer period before a strong conclusion is reached.
