Patients' perceptions of having had freedom of choice in treatment decision-making are shown to have implications for their quality of life. It is, therefore, important to determine what factors underlie these perceptions. One factor that has been studied is whether or not patients believed that their doctor had offered choice of treatment. However, even when choice is actually offered, patients may still feel that they have no choice. Little attention has been paid to other factors that may contribute to patients' perceptions of having had no choice. Our purpose was to explore (1) whether early-stage breast cancer patients perceived to have had a choice with regard to adjuvant chemotherapy, and (2) their reasons for having perceived no choice.
The determinants of no choice that we examined were: (1) (preferred) involvement in treatment decision-making, (2) perceived clinical benefits of chemotherapy (e.g., cure), (3) perceived psychological benefits (e.g., less worries), and (4) perception of being able to cope with the side effects. All predictors, as well as patient and clinical characteristics, were entered simultaneously in a multiple logistic regression analysis and non-significant predictors were removed step-by-step, until only significant predictors (p<0.05) remained. Because determinants may differ between patients with experience of chemotherapy and those without, both treatment groups were analyzed separately.
Four hundred and forty-six patients filled out the questionnaire (62%). Sixty-six percent of patients who had been treated with chemotherapy and 86% of inexperienced patients had perceived no treatment choice. In both treatment groups, patients who preferred a shared role or a passive role in treatment decision-making were statistically significantly more likely to have perceived no treatment choice than patients who preferred an active role. Surprisingly, beliefs about the clinical and psychological benefits of chemotherapy did not influence patients' perceptions of having had choice of treatment.
If we adhere to patient autonomy and shared decision making, we may consider the perception of no treatment choice as a negative outcome of treatment decision-making. However, if this is the result of the patients' preference for less active involvement in treatment decision-making, the topic of perception of no treatment choice may be viewed in a different light.
患者对在治疗决策中拥有选择权的认知已被证明会对其生活质量产生影响。因此,确定这些认知背后的因素很重要。一个已被研究的因素是患者是否认为他们的医生提供了治疗选择。然而,即使实际提供了选择,患者可能仍然觉得自己没有选择。很少有人关注可能导致患者认为自己没有选择的其他因素。我们的目的是探讨:(1)早期乳腺癌患者是否认为在辅助化疗方面有选择;(2)他们认为没有选择的原因。
我们研究的无选择的决定因素包括:(1)(偏好的)参与治疗决策的程度,(2)对化疗临床益处(如治愈)的认知,(3)对心理益处(如担忧减少)的认知,以及(4)对能够应对副作用的认知。所有预测因素以及患者和临床特征同时纳入多元逻辑回归分析,逐步剔除无显著意义的预测因素,直到仅保留显著预测因素(p<0.05)。由于有化疗经验的患者和没有化疗经验的患者的决定因素可能不同,因此对两个治疗组分别进行分析。
446名患者填写了问卷(62%)。接受化疗的患者中有66%以及没有化疗经验的患者中有86%认为没有治疗选择。在两个治疗组中,与偏好积极参与治疗决策的患者相比,偏好共同决策或被动参与治疗决策的患者在统计学上更有可能认为没有治疗选择。令人惊讶的是,对化疗临床和心理益处的认知并未影响患者对是否有治疗选择的认知。
如果我们坚持患者自主性和共同决策,我们可能会将认为没有治疗选择视为治疗决策的负面结果。然而,如果这是患者偏好较少积极参与治疗决策的结果,那么对没有治疗选择的认知这一话题可能会有不同的看法。
