There is a rising health concern among people in the post-pandemic era. It is important for the healthcare service provider to understand the customers' needs and provide superior service quality to the patients. In this study, we determine the factors that impact the service quality of healthcare service providers. Then, we measure the customer behaviour intention score of each customer using the factors of the healthcare service quality that help the service providers to understand the customers’ favorable and unfavorable behaviour influencing their repurchase decision. We find that the customer behaviour intention is highly impacted by reliability and tangibility, followed by empathy and assurance. We also perform customer segmentation using cluster analysis. The insights reveal that the customers are either fast-service-seekers or value-seekers. Both customer segments are significantly different, and different strategies are required to provide better service to each specific segment. This provides interesting insights to healthcare service providers to devise strategies for customer retention and acquisition, along with fulfilling customer needs.
