研究目的: |
主要目的:评估“六阶段递进式培训”对渝东北地区基层医疗机构麻醉医生超声引导神经阻滞(UGNB)综合能力(理论测试+识图测试)的提升效果,并比较培训组与对照组的组间差异。 次要目的:评估培训对麻醉医生UGNB操作成功率、并发症发生率(目标<1%)、年开展例数及UGNB占全部麻醉比例的影响;评估培训对麻醉医生操作信心度和超声解剖识别能力自评的影响;为基层麻醉技术规范化培训提供效果证据,探索可推广的培训模式。 |

|
Objectives of Study: |
Primary Objective:To evaluate the effectiveness of a structured six-stage progressive training program on ultrasound-guided nerve block (UGNB) competency—assessed by a composite score of theoretical knowledge (60 points) and image recognition (40 points)—among primary care anesthesiologists in Northeastern Chongqing, and to compare post-training outcomes between the training group and the parallel control group.Secondary Objectives:To evaluate the impact of the training on UGNB procedural success rate, complication rate (target <1%), annual UGNB case volume, and the proportion of UGNB among all anesthesia techniques;To assess the effect of the training on self-reported procedural confidence (1–5 scale) and ultrasound anatomy recognition ability (0–10 scale);To provide effectiveness evidence for standardized UGNB training in primary care settings and to explore a scalable training model for rural anesthesia capacity building. |

随机方法(请说明由何人用什么方法产生随机序列): |
随机单位: 以具备超声设备的基层医疗机构为随机单位(整群随机),以避免同一医院内培训组与对照组医生的技术沾染。 随机方法: 采用分层区组随机。将医院按麻醉医生人数分为两层——层1:1名医生;层2:≥2名医生。在各层内,按1:1比例将医院随机分配至培训组或对照组。 随机序列产生: 由独立统计师使用SPSS 26.0(或R 4.3.1)软件生成随机数字表。设定固定种子数以保证可重复性。随机分组结果 |

Randomization Procedure (please state who generates the random number sequence and by what method): |
Unit of Randomization: The hospital (cluster randomization) is the unit of randomization. Cluster randomization at the hospital level is adopted to prevent contamination between training-group and control-group anesthesiologists working within the same institution. Randomization Method: Stratified block randomization will be employed. Hospitals will be stratified by the number of anesthesiologists (Stratum 1: 1 anesthesiologist; Stratum 2: ≥2 anesthesiologists). Within each stratum, hospitals will be randomly assigned in a 1:1 ratio to either the training group or the control group. Sequence Generation: The random allocation sequence will be generated by an independent statistician using SPSS 26.0 (or R 4.3.1) with a fixed seed number to ensure reproducibility. The randomization results will be sealed and stored as a blinded allocation file. The project coordinator will open the allocation file and execute group assignment after all baseline assessments are completed. |
