Older adults often have multiple medical conditions that necessitate the management of various medications, leading to complex disease-related medication management that frequently results in medication non-adherence. The impact of non-adherence on older adults and healthcare professionals is further examined within this population. The purpose of this quality improvement project is to increase Nurses’ use of a Health Promotion Model (HPM) to improve medication adherence in older adults. This initiative was guided by evidence-based practice literature and the nursing theorist Dr. Nola Pender's Health Promotion Model. An HPM tool has been designed as a practical educational resource for nurses in the outpatient Home-Based Primary Care (HBPC) program of a Rhode Island Hospital. Its objective is to empower nurses to use the HPM as a strategic tool to develop evidence-based, patient-specific educational resources and counseling services to enhance medication adherence among older adult patients. Nurses in this setting are well-suited for this initiative due to their consistent provision of medication education and management to patients, whether in their homes or by telephone. Participating nurses will receive educational sessions on the HPM tool before implementing it in their work. A pre- and post-test questionnaire will be administered to nurses to evaluate the effectiveness of the intervention tool. The desired outcome for this project is for nurses to increase their knowledge and confidence in using the HPM.
