This study assessed patient satisfaction with emergency room (ER) services in a private hospital in Santiago City, Isabela. It aimed to identify factors influencing care perceptions and propose strategies to improve nursing practice. Patient satisfaction is a key indicator of healthcare quality, shaped by staff competence, communication, environment, and efficiency. A quantitative descriptive-inferential design was used, employing the Brief Emergency Department Patient Satisfaction Scale (BEDPS). A total of 156 patients who received ER services from May to June 2025 were surveyed through convenience sampling. Descriptive statistics measured satisfaction levels, while Mann-Whitney U and Kruskal-Wallis H tests examined differences across demographic and clinical profiles. Findings showed that patients and families were generally highly satisfied: physician care (M = 3.61), family satisfaction (M = 3.58), staff performance (M = 3.53), and patient care (M = 3.61). The environment, while lowest, still received a favorable rating (M = 3.18, Very Satisfied). No significant differences were found based on age, sex, civil status, or patient classification (p > 0.05), indicating equitable service delivery. The results highlight the importance of professional competence, empathetic communication, and family involvement in shaping positive ER experiences. While interpersonal aspects were rated highly, areas for improvement include reducing noise, enhancing cleanliness, and upgrading facilities. In conclusion, patients viewed ER services as generally satisfactory, with physician care and staff performance identified as key strengths. The study recommends enhancing the physical environment, providing regular staff training on empathy and communication, and sustaining patient-centered, equitable nursing care to further improve service quality.
