Objective: To investigated the concept and clinical practice of patient-controlled analgesia (PCA) in the treatment of cancer pain. Methods: Doctors, nurses, pharmacists from the oncology department, pain department, or hospice department were investigated using an electronic questionnaire from December 1 to December 31, 2021. In addition to the basic information, there were 26 questions were collected, including the current situation of cancer pain treatment, the concept of medical staff on PCA treatment of cancer pain and the clinical practice of PCA. Results: Questionnaires from 2 872 medical staff were collected from 993 hospitals in 30 provincial administrative units. Only 34.8% (955/2 748) of medical staff considered that the satisfaction rate of cancer pain control was over 75%, and 27.9% (548/1 968) of medical staff convinced that the satisfaction rate of breakthrough pain control was less than 50%. 97.1% (2 439/2 513) of medical staff considered that PCA could be effectively used for cancer pain treatment. The proportion of medical staff in secondary and tertiary hospitals who thought that PCA was applicable to cancer pain that could not be effectively alleviated by standardized non-invasive drug administration was 64.6% (319/494) and 69.1% (1 262/1 826) respectively, which was higher than that in primary hospitals [57.0% (110/193)] (P=0.002). In different occupations, the proportion of nurses who convinced PCA treatment of cancer pain increased the risk of addiction and drug overdose was 62.8% (431/686) and 76.1% (522/686), respectively, which was higher than doctors [39.2% (670/1709) and 58.2% (995/1709), respectively] and pharmacists [49.2% (58/118) and 65.3% (77/118), respectively] (all P<0.001). There was no significant difference in type of pump, route of administration, mode of infusion, protocol for PCA administration and selection of common medication in PCA treatment of cancer pain among different hospitals (all P>0.05). The calculation of continuous infusion dose and rescue dose of PCA was not uniform among different hospitals. After initiation of PCA, 71.7% (1 226/1 709) of hospitals had insufficient analgesia and most of them needed to be adjusted for 1-3 times to achieve satisfactory analgesia. Conclusion: Medical staff have insufficient cognition of PCA treatment of cancer pain and there is a lack of unified guidance in clinical practice. Therefore, it is an urgent need to develop an expert consensus on PCA treatment of cancer pain.
目的： 了解我国医护人员应用患者自控镇痛（patient controlled analgesia，PCA）治疗癌痛的观念和临床实践情况。 方法： 2021年12月1至31日，以电子问卷形式，在全国范围内对肿瘤科、疼痛科、安宁疗护科等癌痛诊疗相关科室的医师、护士和药剂师发放PCA治疗癌痛调研表。除基本信息外，共收集26个相关问题。统计分析癌痛治疗现状、医护人员对PCA治疗癌痛的观念和PCA临床应用实践3个方面的内容。 结果： 共收集到来自全国30个省市的993家医院、2 872份调研问卷。只有34.8%（955/2 748）的医护人员认为癌痛控制满意率超过75%，27.9%（548/1 968）的医护人员认为爆发痛控制的满意率不足50%。97.1%（2 439/2 513）的医护人员认为PCA可以有效用于癌痛治疗，二、三级医院医护人员认为PCA适用于规范化无创给药不能有效缓解癌痛的比例分别为64.6%（319/494）和69.1%（1 262/1 826），高于一级医院的57.0%（110/193）（P=0.002）。不同职业中，护士认为PCA治疗癌痛增加成瘾性以及导致药物过量的比例为62.8%（431/686）和76.1%（522/686），高于医师的39.2%（670/1 709）和58.2%（995/1 709），以及药剂师的49.2%（58/118）和65.3%（77/118）（均P<0.001）。不同医院间PCA治疗癌痛在镇痛泵类型、给药途径、输注模式、用药方案及常用药物方面差异均无统计学意义（均P>0.05），PCA持续输注量和解救剂量的计算比例不统一，在启动PCA后，有71.7%（1 226/1 709）的医疗机构存在给予患者镇痛不足，多数需要调整1~3次才能达到满意镇痛。 结论： 我国医护人员对于PCA治疗癌痛的观念认知不足，临床实践中缺乏统一指导，应尽快形成PCA治疗癌痛专家共识。.
