Two dimensions of service quality (tangibles and responsiveness) generally explain the dispersion of satisfaction with healthcare services by 51.5%. Based on literature and research results, developed by authors model of service quality management at healthcare institution shows the essential four steps from planning to improvement, ensuring systematic improvement of service quality. Keywords: healthcare service quality; satisfaction with service quality; SERVQUAL service quality dimensions; model of healthcare service quality management. [From the publication]
