Introduction The study focuses on analyzing the level of awareness among oncological patients, their perception of their health status, and expectations regarding radical surgical intervention. It assesses changes in patients' attitudes toward their diagnosis, therapeutic options, and prognosis both preoperatively and postoperatively. The research involves a systematic collection of value-based medical history through structured interviews, enabling the identification of key factors influencing patient experience and decision-making processes in oncological treatment.

The study is particularly focused on collecting patients' value-based medical history before and immediately after surgery. Respondents must meet specific inclusion criteria to undergo surgical procedures classified as BUPA D-hemicolectomy, rectal resection, urological surgery (cystectomy or radical nephrectomy), or resection of malignant brain tumors. Patients scheduled for surgical intervention initially underwent an assessment in the anesthesiology clinic, where they were informed about the possibility of participating in the study. Upon signing the informed consent, the collection of their value-based medical history commenced. Following surgery and prior to discharge from the intensive care unit (ICU), a subsequent interview was conducted, during which responses were compared and potential changes in personal attitudes were evaluated [1,2, 3].

The value-based medical history was obtained following a predefined set of questions. The aim of the study is to determine whether collecting value-based medical history reveals patients' level of awareness regarding their illness, their expectations, and any shifts in attitudes after surgery and hospitalization in the ICU at ARIM KNTB Zlín. The findings may indicate further hypotheses related to the collection of value-based medical history.
