Aim: to investigate the age-related characteristics of patients’ satisfaction with the quality and accessibility of primary health care provided by general practitioners- family doctors (GPs) in Kyiv. Materials and Methods: A survey of 510 patients assessed satisfaction with the accessibility and quality of medical care provided by GPs using a 5-point Likert scale (4 and 5 points were considered as positive responses to the questions [«satisfaction»]; 1-3 – as negative [«dissatisfaction»]; and 0 – as undecided ones). Results: The study demonstrated the significant trends in the opposite responses to certain survey questions across the different respondents` age groups. In particular, we revealed the advancing age-related (from <30 to >60 years group) trends toward satisfaction rate decrease with respect to the organization of an appointment with one`s GP, and satisfaction rate increase – regarding the availability of obtaining prescriptions for medicines. Patient dissatisfaction with the quality of medical care provided by GPs was influenced by three factors: appointment organization, accessibility of referrals to specialists, and the doctor’s attitude toward the patient (AUC for logistic regression model: 0,965 [95 % CI: 0,946-0,979]). Conclusions: The presence of age-related features of patients` satisfaction with the quality of medical care has been established, which should be taken into account when planning measures to improve the management of medical care quality in healthcare facilities. The key factors influencing the level of patients` dissatisfaction with the quality of primary healthcare were the organization of appointment scheduling, the availability of referrals to specialists, and the attitude of the GP towards the patient during the appointment.
