Introduction. Marketing of healthcare services is a process of developing, communicating and passing values to people who make use of healthcare. It also includes managing contacts with patients in order to provide benefits both to the healthcare entity and to the patient. Healthcare entities mainly focus their marketing and information activities on the Internet, which is a common and most frequently used way of communication, increasingly displacing the traditional ones. Aim. To know the opinions of present and future patients on the needs and assessment of the availability of information about the offer of health services provided by particular healthcare entities on the Internet, as well as to identify the group of people who choose a provider of medical services based on the opinions about doctors who put information about their services on the Internet. Material and methods. The survey was conducted using an electronic questionnaire form shared in social media. It included 111 respondents who voluntarily and anonymously participated in the study. The questionnaire contained 22 author questions regarding the use of information about healthcare entities and services available on the Internet, as well as the factors determining the choice of the doctor or medical institution. Results and conclusions. The Internet is a widespread source of information on a healthcare entity in the opinion of present and future patients. Despite the frequent use of the Internet by patients, few of them use the electronic registration option, although this number is steadily increasing. Patients are aware of the risks associated with the existence of a network of false information about the subjects related to health. Information about disease is mostly searched by young and middle-aged people, the most popular sources being online forums, blogs and medical portals. Despite the awareness of the risk of self-diagnosis and self-treatment, patients still continue to use the Internet for this purpose.
