Abstract: This quasi-experimental research aimed to develop and evaluate the effectiveness of a Humanitude-driven care program for elderly patients in the medical ward of Trat Hospital. The study, conducted from March to May 2024, included 15 nurses, 34 caregivers, and 34 elderly patients selected through purposive sampling. The intervention comprised a 10-activity program based on Humanitude principles. Post-intervention, both nurses and caregivers showed significant knowledge improvement in elderly care (p < .01). Furthermore, nurses' practical abilities and satisfaction levels significantly surpassed the established benchmarks (p < .01). Crucially, the elderly patients' functional capacity, as measured by the Barthel Activities of Daily Living (ADL) Index, demonstrated a significant improvement (p < .01). This study confirms that the Humanitude-driven program effectively enhances the care process by fostering engagement, thereby promoting a higher quality of nursing services and supporting sustainable practices in elderly care.
