The decisional balance, attitudes, and practice behaviors, its predicting factors, and related experiences of advance care planning in Taiwanese patients with advanced cancer

Abstract

Background: Patients with advanced cancer are prone to experience burdensome physical, psychological, and financial consequences. Healthcare providers may not fully appreciate advanced cancer patients' medical care autonomy, such as at that emboded by Advance Care Planning (ACP), and by doing so may compromise their quality of end-of-life (EOL). Hence, it is essential for healthcare providers to effectively assess and communicate with patients' regarding their medical decisions before their patients are incapacitated by their disease progression. The purpose of this investigation was to describe the decisional balance, attitudes, and practice behaviors of ACP and its predictors of ACP-related experiences in Taiwanese patients with advanced cancer.

Methods: This cross-sectional, descriptive study employed a mixed-methodsquantitative and qualitative design with a sample of 166 patients that were purposely recruited from in-patient oncology units at a regional teaching hospital in southern Taiwan. Study data consisted of patient replies to a 34-item self-report tool, Decisional Balance, Attitudes, Practice Behaviors of ACP (DAP-ACP) and 4 semi-structured questions.

Result: Findings indicated that, in general, study participants exhibited favorable ACP-decisional balance and positive ACP-attitudes & practice behaviors. The results also indicated that gender, educational level, and cancer diagnosis were associated with significant differences on the "ACP-decisional balance" and "ACP-attitudes" scales. In addition, our findings documented that the participants' gender and educational level were significant predictors of both ACP-decisional balance and ACP-attitudes. Furthermore the participants' ACP-practice behaviors were predicted by ACP-decisional balance, but not with their ACP-attitudes. The qualitative analysis of the semi-structured questions identified six themes in responses to current medical decision making (e.g., compliance with physician instructions, family engagement in treatment decision-making); and eight themes pertaining to future ACP-related concerns were identified (e.g., family conflict, effectiveness of time-limited trials).

Conclusion: To promote patients' engagement in ACP, the healthcare professional need to assess and advocate patients' concerns or attitudes regarding ACP in a timely manner. In addition, factors or concerns that might influence patients' responses to ACP derived from both the quantitative and qualitative findings of this current study need to be considered especially in initiating the dialogue regarding ACP with patients with advanced cancer.
