The aim of the study was to find out how nursing behavior is perceived by nurses and patients with thromboembolic disease. The sample consisted of 264 patients, and a comparative sample consisted of 92 nurses. The standardized measuring tool Caring Behaviors Inventory (CBI-24) was used for the data collection, supplemented by questions of its own design. Exploratory methods and chi-square test of independence were used for the needs of statistical processing. Based on the results it can be concluded that the perception and assessment of the provided nursing care was more positively evaluated by the patients.
