Background
Shared decision-making (SDM) is increasingly recognized as a preferred model for cancer care, yet its relationship with patient-reported outcomes remains unclear in the context of Traditional Chinese Medicine (TCM). This study examined the associations of SDM with decision-making satisfaction, treatment decision usefulness, and health-related quality of life (HRQoL) in TCM.
Methods
This multicenter cross-sectional study was conducted among lung cancer patients treated with TCM anti-cancer injections in Shanghai, China. Participants completed questionnaires assessing SDM, decision-making satisfaction, treatment decision usefulness, and HRQoL. Structural equation modeling was conducted to examine the hypothetical model.
Results
A total of 347 participants (46.1% female, 64.8 ± 8.7 years) were included. Using the EQ-5D-5 L index value to represent HRQoL, SDM not only directly positively affected both decision-making satisfaction (β = 0.438, 95%CI: 0.206 – 0.639) and treatment decision usefulness (β = 0.380, 95%CI: 0.172 – 0.577), but indirectly positively affected HRQoL through treatment decision usefulness (β = 0.117, 95%CI: 0.028 – 0.290). A similar pattern was identified using the EQ-VAS score, with significant direct effects on decision-making satisfaction (β = 0.438, 95%CI: 0.206 – 0.639) and treatment decision usefulness (β = 0.380, 95%CI: 0.172 – 0.577), as well as an indirect effect on HRQoL through treatment decision usefulness (β = 0.083, 95%CI: 0.009 – 0.224).
Conclusions
SDM plays a positive role in improving decision-making satisfaction, treatment decision usefulness, and HRQoL among patients receiving TCM. These findings indicate its intrinsic value in patient–provider interactions and its associated benefits, potentially fostering the practice of SDM in TCM.
