Evaluating the absolute difference in pain intensity and the percentage difference in pain intensity could facilitate an understanding of pain reduction among cancer patients during repeated hospitalizations. Examinations of the absolute differences in pain intensity and the percentage differences in pain intensity according to the worst pain intensity and last evaluated pain intensity before discharge are lacking. The aim of this study was to evaluate the absolute and percentage difference in pain intensities among cancer patients with moderate or severe pain from their 1st to 18th hospitalizations from 2011-2013. A population-based retrospective cohort study was conducted. Pain intensity was assessed using scales and was recorded in a nursing information system. The absolute and percentage difference in pain intensities were examined via the one-sample Kolmogorov-Smirnov test, and group differences in moderate or severe pain were evaluated with the Mann-Whitney U test. For moderate pain patients, the mean absolute difference in pain intensity was 1.52, and the percentage difference in pain intensity was 29.0%; both these values were significant. More significant changes in the absolute and percentage difference in pain intensities were associated with severe pain patients. Both the average absolute difference in pain intensity (3.09) and the percentage difference in pain intensity (38.5%) in patients with severe pain were significantly higher than the average absolute difference in pain intensity (1.52) and the percentage difference in pain intensity (29.0%) in patients with moderate pain. Cancer patients with moderate and severe pain experienced pain reductions of approximately 30% and 40%, respectively. Early pain management intervention in patients with severe pain is necessary to achieve an obvious analgesic effect, and the formula of the percentage difference in pain intensity should be incorporated into the nursing information system to alert clinicians for early detection of the effectiveness of cancer pain management.
评估疼痛强度的绝对差异和疼痛强度的百分比差异可以帮助理解癌症患者在多次住院期间的疼痛减轻情况。缺乏根据出院前最痛强度和最后评估的疼痛强度评估疼痛强度的绝对差异和百分比差异的研究。本研究旨在评估 2011-2013 年期间 18 次住院期间中度或重度疼痛的癌症患者的疼痛强度的绝对和百分比差异。这是一项基于人群的回顾性队列研究。疼痛强度使用量表进行评估，并记录在护理信息系统中。通过单样本 Kolmogorov-Smirnov 检验检查疼痛强度的绝对和百分比差异，并使用 Mann-Whitney U 检验评估中度或重度疼痛的组间差异。对于中度疼痛患者，疼痛强度的平均绝对差异为 1.52，疼痛强度的百分比差异为 29.0%；这两个值都是显著的。严重疼痛患者的疼痛强度的绝对和百分比差异的变化更为显著。严重疼痛患者的疼痛强度的平均绝对差异（3.09）和疼痛强度的百分比差异（38.5%）均明显高于中度疼痛患者的疼痛强度的平均绝对差异（1.52）和疼痛强度的百分比差异（29.0%）。患有中度和重度疼痛的癌症患者分别经历了约 30%和 40%的疼痛减轻。对严重疼痛患者进行早期疼痛管理干预是必要的，以达到明显的镇痛效果，并且应该将疼痛强度百分比差异的公式纳入护理信息系统，以提醒临床医生早期发现癌症疼痛管理的效果。
