Gap analysis of service quality and associated factors at the oncology center of Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia, 2022: a cross-sectional study.

Patient perceptions of the quality of service they received were lower than their expectations of the quality of service in all service quality aspects at Tikur Anbessa Specialized Hospital's oncology centre, implying unmet quality expectations from the oncology service users, with tangibility, assurance and empathy being the dimensions with the highest gap recorded, respectively. Therefore, the hospital and other stakeholders should strive to exceed patient expectations and the overall quality of care.
