Factors affecting lung cancer patients' intention to perform early postoperative exercise: a qualitative study based on theory of planned behavior

Abstract

Background: Early postoperative exercise is effective in improving the prognosis of postoperative lung cancer patients, but compliance was lower than expected. Factors affecting lung cancer patients' intention to perform early postoperative exercise were unclear.

Purpose: To discuss the factors affecting lung cancer patients' intention to perform early postoperative exercise based on the Theory of Planned Behavior.

Methods: This was a qualitative study. Twenty-five lung cancer patients were recruited using purposive sampling, and semi-structured face-to-face interviews were performed. The reflexive intuitive thematic analysis method was used, and triangulation was employed to ensure the credibility of the study.

Results: Results of this study identified 8 themes from 3 aspects. For behavioral attitudes, two themes emerged: (1) Aware of the benefits of postoperative exercise, (2) Underestimate the importance of postoperative exercise. For subjective norms, four themes emerged: (1) Influence of caregiver support on carrying out postoperative exercise, (2) Short-term supervision of medical staff, (3) Positive driving effect from other patients, and (4) Motivation due to family responsibility. For perceived behavior control, two themes and six sub-themes emerged: (1) Obstacles before actual exercise (Lack of adequate knowledge of postoperative pulmonary exercise, Less active in seeking related knowledge about rehabilitation exercise, and Misconceptions about rehabilitation exercise); (2) Unpleasant experiences during exercise (Physical discomfort, Limited space and depressive atmosphere, and Psychological burden).

Conclusions: Several factors could affect lung cancer patients' early postoperative exercise behavior. Healthcare professionals should fully understand these factors from patients' perspectives. Special interventions should be designed for the patients and their caregivers to correct cognitive bias, reduce obstacles, and promote compliance with exercise.
