Introduction. In the context of asymmetric doctor-patient relationships, ensuring the information availability of medical care is an important component of the patient's interaction with the healthcare system, which is significant in diseases of the peripheral arteries in the presence of risk factors for complications. The development of a patient information system in this group is extremely important. The purpose of the study is to evaluate the effectiveness of measures to optimize the information accessibility of medical care for diseases of the peripheral arteries. Materials and methods. The study included several stages implemented in 2023 in St. Petersburg: a survey of 75 doctors and 350 patients with peripheral artery diseases on the availability of medical care, the implementation of an organizational experiment based on one of the polyclinics, a control survey of 220 patients on its results. The analysis of the obtained data was carried out using the Statistics 21 software package. Results. According to specialist doctors, the main responsibility for the effectiveness of medical care lies with patients who do not seek it in a timely manner (82.4 per 100 surveyed doctors), show insufficient commitment to maintaining health (67.8 per 100 surveyed doctors), do not follow the doctor's recommendations (39.2 per 100 surveyed doctors). Patients are insufficiently aware of the disease (61.8%), only 56.1% are satisfied with the doctor's explanations, 33.4% of the information is not clear. After taking measures to optimize the information accessibility of medical care, patient satisfaction with the doctor's explanations increased to 80.0% (t = 3.6, p
