The article presents the research that reveals the complexity of the patient hospital choice process and, in the context of the research data, enables the evaluation of the patient hospital choice factors influencing their decision. The problem of hospital choice is topical both in Lithuania and other EU and world countries. It is a complex process that requires the evaluation of the poly-functionality of the choice factors: the character of the patient disease and their state of health, the characteristics of the hospital, the interactive relationship between the hospital staff, the patient’s relatives, and Internet access. The research sample consisted of 477 participants aged between 18 and 89, treated in various hospitals throughout the country. Based on the results of the research presented in the article, one can argue that the factors having the greatest impact on patients’ choice of hospital include the advice of friends and significant others, personal experience, and the advice of their family doctor. The main prerequisites for choosing a hospital named by the patient respondents were the qualification of the medical staff, the quality of health care, communication between doctors and patients, the geographical location of the hospital, and its accessibility.
