An Educational Intervention to Improve Preoperative Beta Blocker Compliance among Adult Outpatients
MetadataShow full item record
This Doctor of Nursing Practice (DNP) project focused on evaluating an educational intervention aimed at improving beta blocker compliance during the preoperative period at Sisters of Charity Hospital. The main objective of this project was to improve patient knowledge, comfort, and compliance regarding beta blockers in the preoperative period. This project used a retrospective chart review to determine if beta blocker compliance was improved in patients who had received the educational intervention, versus patients who did not. Hildegard Peplau’s theory of Interpersonal Relations in Nursing was used to guide this project. Participants consisted of 75 patients (25 who received the intervention and 50 who did not) as well as seven nurses who delivered the intervention. Data was collected through the use of chart review, written survey, and the Morisky Medication Adherence Scale (MMAS-8) standardized questionnaire. The Pearson chi-square test was used to evaluate patient beta blocker compliance related to the intervention. The results showed no statistically significant difference (X² (1) = 1.749; p=.186) in beta blocker compliance in patients who received the intervention, versus patients who did not. However, additional analyses found significant differences between beta blocker compliance and number of medications taken (p=.000), as well as beta blocker compliance and age (p=.000). This project may have potential to improve patient beta blocker compliance along with patient knowledge regarding this medication by identifying the lack of compliance shown in older patients as well as those taking a high number of medications. Utilizing this intervention could potentially limit poor patient outcomes related beta blocker withdrawal as well as reducing healthcare costs related to hospitals having to dose a missed beta blocker. Future research should look into a universal method of delivering preoperative medication instructions and evaluating patient knowledge regarding those medications to improve adherence in the preoperative period.
