Supporting Parkinson's disease medication safety for nurses in the acute care setting through an educational intervention study

Introduction: Patient medication safety in the acute care setting is a foundational action provided by nurses and healthcare providers for safe patient care. Hospitalization of patients with Parkinson's disease (PD) can be dangerous due to the unique and variable medication regimen required. Patients with PD often have their medication administered inappropriately in the acute care setting (e.g., holding a PD medication in preparation for surgery, not administering the medication on the patient's home schedule, and delaying administration). The research question posed in this study was the following: does a PD medication educational intervention in the clinical setting enhance knowledge, comfort, and competence of practicing nurses in the care of patients with PD regarding their medication safety? Design: A mixed methods study design was used for this 5-month, two-part study with a sample of practicing RNs at three different hospitals. Part one of the study assessed nurses' initial knowledge of PD and PD medication safety and included an educational intervention. Part two of the study occurred 3 months later and evaluated if knowledge from the educational intervention was retained. Methods: The study was conducted in two parts and included a pre-test, educational intervention, post-test, and follow-up test 3 months later. The educational intervention consisted of a 15-minute video of two PD advanced practice nurses being interviewed regarding the general care of a patient with PD. The pre-test, post-test, and follow-up test were identical and consisted of six questions regarding knowledge, comfort, and self-perceived competency. Participants were additionally asked three open-ended questions at follow-up to gain insight on the effectiveness of the educational intervention. Results: A total sample of 252 RNs participated in this study. Statistically significant improvements in knowledge, comfort, and self-perceived competency were observed in the post-test scores compared to pre-test scores. These statistically significant improvements were retained after 3months, despite a 42.9% decrease in the number of responders (n = 252 vs. n = 144). Additionally, compared to the post-test, there were no statistically significant declines in knowledge, comfort, or competency in the follow-up test. Qualitative findings indicated that the training regarding PD medications was retained and found to be valuable, even if it was seldom applied in practice. Conclusion: A revi
