Healthcare is vital for the overall well-being of an individual. The service quality in healthcare is a matter of great importance for health institutions across the world. With increasing patient awareness and rising competition among hospitals, patient perception of healthcare quality has become very relevant. This study aims to review the literature to explore the concepts of perceived service quality, customer satisfaction, and behavioural intentions. The study has attempted to look into the relationship between perceived healthcare service quality, patient satisfaction, and behavioural intentions of patients. Healthcare service quality is measured using SERVQUAL dimensions as well as other dimensions specific to the healthcare sector. The findings clearly show that perceived healthcare service quality, patient satisfaction, and behavioural intentions are closely related to each other, and high-quality services lead to satisfied patients who further exhibit positive behavioural intentions.
