Qualitative study of kinesiophobia in patients with tumors after PICC catheterization.

To explore the kinesiophobia experience of patients with tumors after PICC catheterization and to analyze patients' views and true inner feelings about kinesiophobia, with the goal of providing a reference for reducing the occurrence of kinesiophobia and enhancing the experience of patients undergoing this procedure. A purposive sampling method was used to select patients with tumors that required the placement of a PICC line in a tertiary hospital in Ningbo City, Zhejiang Province, as the research object. A semistructured in-depth interview method was used for data collection, and the content of the interview was analyzed through a seven-step analysis method of Colaizzi's phenomenological data. (1) Physiological discomfort after catheter placement leads to kinesiophobia behavior (2) Psychological stress after catheter placement triggers kinesiophobia reactions 3.Catheter information affects kinesiophobia 4. kinesiophobia manifestations were observed in patients during catheter maintenance and home management. kinesiophobia behavior in oncology patients with a PICC line presents multidimensional dynamic evolution characteristics, and its core triggers involve the interaction of physiological reactions, psychological stressors, and daily behaviors, which require more attention and early intervention to reduce potential adverse reactions.
