To develop clinically meaningful improvement thresholds in both the 17-item and the 6-item Hamilton Rating Scale for Depression (HRSD) total scores in depressed outpatients.
The post-hoc analysis included all adult outpatients with non-psychotic major depressive disorder in the STARD trial who entered and exited the first treatment step (up to 14 weeks of citalopram) with a complete set of study measures at baseline and exit and at least one post-baseline measure. Within-patient change and linear regression anchor-based analyses were conducted to define meaningful and substantial changes in the HRSD and HRSD using three patient-reported outcomes [Work and Social Adjustment Scale (WSAS), Quality of Life Enjoyment and Satisfaction-Short Form (Q-LES-Q-SF); Mini-Q-LES-Q] obtained at baseline and exit from the first treatment step in STARD.
Linear regression analyses identified a meaningful change threshold for the HRSD as 3.9 [3.7-4.1] [lower, upper 95% CI] and a substantial change as 7.8 [7.4-8.3] with the WSAS. Analogous thresholds based on the Q-LES-Q-SF were 5.8 [5.5-6.1] and 11.6 [11.0-12.2], respectively, and 4.9 [4.7-5.2] and 9.9 [9.3-10.4] for the Mini-QLES-Q, respectively. For the HRSD, linear regression analyses with the WSAS identified a meaningful change as 2.2 [2.1-2.4], while a substantial change was 4.5 [4.2-4.7]. Analogous figures based on the Q-LES-Q-SF were 3.2 [3.0-3.4] and 6.4 [6.1-6.8]. Similarly, based on the Mini-QLESQ, results were 2.8 [2.6-2.9] and 5.6 [5.3-5.9]. For both the HRSD and the HRSD, within-patient analyses produced less precise estimates of the same change thresholds with substantial overlap between groups. Based on the WSAS, a clinically meaningful change in the HRSD total score was 9.6 (SD = 6.5), while a substantial change was 15.0 (SD = 6.7). Analogous change thresholds based on the Q-LESQ-SF were 12.9 (SD = 6.2) and 16.8 (SD = 6.4), respectively. For the Mini-Q-LES-Q, thresholds were 10.9 (SD = 6.5) and 16.1 (SD = 6.2).
A 4-6 point change in the HRSD is clinically meaningful; a 7-12 point change is clinically substantial. For the HRSD, analogous estimates were 2-3 and 4-7 point changes, respectively.
制定门诊抑郁症患者17项及6项汉密尔顿抑郁量表(HRSD)总分具有临床意义的改善阈值。
事后分析纳入了STARD试验中所有患有非精神病性重度抑郁症的成年门诊患者,这些患者进入并完成了首个治疗阶段(长达14周的西酞普兰治疗),在基线期、治疗结束时均有全套研究测量指标,且至少有一项基线后测量指标。采用患者内变化分析和基于线性回归锚定的分析方法,利用STARD试验首个治疗阶段基线期和结束时获得的三项患者报告结局[工作与社会适应量表(WSAS)、生活质量享受与满意度简表(Q-LES-Q-SF);简易Q-LES-Q]来定义HRSD及HRSD中有意义和显著的变化。
线性回归分析确定,基于WSAS,HRSD有意义的变化阈值为3.9[3.7 - 4.1][下限,上限95%CI],显著变化阈值为7.8[7.4 - 8.3]。基于Q-LES-Q-SF的类似阈值分别为5.8[5.5 - 6.1]和11.6[11.0 - 12.2],基于简易Q-LES-Q的分别为4.9[4.7 - 5.2]和9.9[9.3 - 10.4]。对于HRSD,基于WSAS的线性回归分析确定有意义的变化为2.2[2.1 - 2.4],显著变化为4.5[4.2 - 4.7]。基于Q-LES-Q-SF的类似数值分别为3.2[3.0 - 3.4]和6.4[6.1 - 6.8]。同样,基于简易Q-LES-Q的结果分别为2.8[2.6 - 2.9]和5.6[5.3 - 5.9]。对于HRSD和HRSD,患者内分析对相同变化阈值的估计不太精确,组间有大量重叠。基于WSAS,HRSD总分有临床意义的变化为9.6(标准差 = 6.5),显著变化为15.0(标准差 = 6.7)。基于Q-LES-Q-SF的类似变化阈值分别为12.9(标准差 = 6.2)和16.8(标准差 = 6.4)。对于简易Q-LES-Q,阈值分别为10.9(标准差 = 6.5)和16.1(标准差 = 6.2)。
HRSD总分变化4 - 6分具有临床意义;变化7 - 12分具有临床显著性。对于HRSD,类似的估计分别为变化2 - 3分和4 - 7分。
