The goal of the study was to find out how and to which extent patients are informed before and after their vascular prosthesis implantation. The criterion for being included in the study was to achieve at least 24 points of Mini Mental State Examination and to meet the established indication criteria for the surgery. The ethical committee of the health care facility and all participants, who were informed on the purpose of the study, agreed with the study. Crohnbach`s alpha was calculated to identify internal consistency and reliability of questionnaires. The study results were processed by Pearson`s chi-squared test at 5% level of significance.The respondents` mean age was 68 years. Prior to the surgery, 66% of the respondents were instructed verbally, 6% in the written form and 28% both verbally and in the written form. After the surgery, 54% of the respondents were instructed verbally, 0% only in the written form and 46% both verbally and in the written form. On the satisfaction scale from 1 (very satisfied) to 5 (very dissatisfied), satisfaction was evaluated with 1.46 (amount of information), 1.47 (comprehensibility), and 1.38 (way of providing information). After the surgery: amount of information – 1.56, comprehensibility – 1.52, and way of providing information – 1.57. The study results show good instructions and patient satisfaction. Suitable and correctly provided information both in verbal and written form contribute to higher patient adherence to treatment.
