为了估计患者对胆结石相关治疗和结果的偏好，并评估偏好如何因患者特征和评分技术而变化，作者根据评分量表（n = 22）和标准赌博（n = 18）随机分配了40名无胆结石患者进行访谈。患者对开腹胆囊切除术（评分平均0.45，标准评分0.78）、腹腔镜胆囊切除术（0.71,0.91）、体外冲击波碎石术（0.77,0.89）、急性胆囊炎（0.36,0.77）、终生胆道绞痛（0.41,0.71）、胆囊切除术后综合征（0.43,0.79）、需要胆酸治疗的无症状结石（0.76,0.96）、手术瘢痕（0.79,0.998）的偏好值（可能值为0 ~ 1）。偏好因年龄、性别或种族而变化不大。标准赌博值与评定量表值高度相关，但显著大于评定量表值。作者得出结论，患者对胆结石相关疾病的偏好通常明显小于1，并且由于使用的缩放技术而显着不同。当患者的偏好被纳入胆结石治疗分析时，应考虑这些结果。
To estimate patient preferences for gallstone-related treatments and outcomes, and assess how preferences vary by patient characteristics and scaling technique, the authors randomly assigned 40 patients without gallstones to interviews based on a rating scale (n = 22) and a standard gamble (n = 18). The patients assigned preference Values (possible values 0 to 1) to open cholecystectomy (mean 0.45 by rating scale, 0.78 by standard gamble), laparoscopic cholecystectomy (0.71, 0.91), extracorporeal shock-wave lithotripsy (0.77, 0.89), acute cholecystitis (0.36, 0.77), lifetime biliary colic (0.41, 0.71), postcholecystectomy syndrome (0.43, 0.79), asymptomatic stone necessitating treatment with bile acids (0.76, 0.96), and surgical scar (0.79, 0.998). Preferences varied little by age, gender, or race. Standard gamble values were highly correlated with, but significantly greater than, rating scale values. The authors conclude that patients' preferences for gallstone-related conditions generally are significantly less than one, and differ markedly by the scaling technique used to derive them. These results should be considered when patient preferences are incorporated into analyses of gallstone treatments.
