Patient satisfaction is crucial in nursing services and could be influenced by nurses' caring behavior. This study aimed to discover the relationship between Swanson's caring nurse approach and patient satisfaction in the 3rd-grade inpatient room. This quantitative descriptive research employed an explanatory survey with a cross-sectional approach. Purposive sampling is the sampling technique used in this research, with a total of 73 participants. Data analysis was conducted using the Chi-square test, and data were collected using an instrument. The results indicated that 47 responders (64.4%) perceived that nurses' caring behavior was not good. Specific indicators revealed that “maintaining belief” was not good for 39 respondents (53%), “knowing” for 53 (73%), “being with” for 45 respondents (62%), “doing for” for 48 respondents (66%), and “enabling” for 49 respondents (67%). Regarding patient satisfaction, 43 people (58.9%) expressed being quite satisfied. Bivariate analysis demonstrated a significant relationship between caring nurses and patient satisfaction, with a p-value of 0.000 or p<0.05. It was recommended that nurses in the inpatient room incorporate improvements in caring behavior into nursing planning and goals. Policies related to the obligation of providing caring actions should be established to enhance patient satisfaction. Nurses were encouraged to consistently apply caring principles, including “maintaining belief”, “knowing”, “being with”, “doing for”, and “enabling”, to ensure patients were satisfied with their care experience.
