研究目的: |
主要目的:验证“医生+AI辅助”较“医生+传统资源(禁用AI)”在诊断与管理综合评分上的优效。 次要目的:比较用时、答案长度/结构、分维度得分、错误/有害建议率与依从度;刻画与“AI单独作答”的相对水平。 |

|
Objectives of Study: |
Primary Objective: To verify the superiority of "Physician + AI assistance" over "Physician + traditional resources (AI prohibited)" in the composite score for diagnosis and management. Secondary Objectives: To compare time spent, answer length/structure, dimension-specific subscores, rates of errors/harmful recommendations, and adherence; and to characterize performance relative to "AI-only responses." |

随机方法(请说明由何人用什么方法产生随机序列): |
分层区组随机(变长区组),计算机生成随机数序列 由独立统计学家(不参与受试者招募与纳入)使用经验证的软件(如 R 或 SAS)按专科与职称进行分层,在各分层内采用1:1 随机区组分配,区组长度设置为 4/6/8 随机变长以降低可预测性;设置并记录固定随机种子(seed)、生成时间与软件版本,形成计算机生成的随机数字序列。随机序列仅由不参与纳入的专人/数据管理员保管,并供中央随机系统调用。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
Stratified permuted-block randomization (variable block sizes) with computer-generated sequence An independent biostatistician (not involved in participant recruitment or enrollment) will generate a computer-based random number sequence using validated software (e.g., R or SAS). Randomization is 1:1 within strata defined by medical specialty and professional rank, employing permuted blocks with variable sizes (4/6/8) to reduce predictability. A fixed random seed, generation time, and software version will be recorded. The allocation sequence is stored securely by a non-enrolling data manager and implemented via a central randomization system. |

盲法: |
盲法类型:评分者盲法(assessor blinding);统计分析阶段组别遮蔽(analysis blinding)。受试医师与干预不可盲。 实施对象: 评分专家:对随机组别(A:医生+AI;B:医生+传统资源)及“AI单独作答”的来源信息均不知情。 统计分析人员:在主分析完成与代码冻结之前,仅接触以 A/B 哑变量标识的组别信息。 实施过程: 提交答案后,由与纳入无关的质控人员对文本与日志进行去标识(移除AI使用痕迹、时间戳/用户名、系统提示等可识别信息),并随机化呈现顺序。 评分采用双评+仲裁:两名独立专家在统一rubric下盲评,分歧由第三专家或共识会议仲裁。 评分平台对评分者隐藏元数据(作答时长、资源使用记录等),必要信息仅用于依从性核查且与评分界面物理隔离。 统计分析在锁库后以预先登记的分析方案执行,组别在主要结果产出前保持遮蔽;敏感性/亚组分析遵循同样遮蔽流程。 盲态维持与解盲: 访问控制与审计日志确保评分材料与组别映射分离;发生重大偏离或安全事件需解盲时,按SOP由PI与数据管理员共同审批,记录原因与时间。 研究结束后统一解盲并归档。 |

Blinding: |
Type of blinding: Assessor blinding and analysis blinding. Participants/interventions cannot be blinded. Who is blinded: Expert raters are blinded to randomized assignment (Arm A: Physician+AI; Arm B: Physician+traditional resources) and to whether a response originates from the "AI-only" reference arm. Statisticians/analysts are group-masked (A/B dummy labels) until completion of the primary analysis and code freeze. Procedures: After submission, materials are de-identified by independent QC staff (removing AI cues, timestamps/user IDs, system prompts, etc.) and presented in randomized order. Scoring uses independent dual ratings with adjudication under a standardized rubric; discrepancies are resolved by a third rater or consensus. The scoring interface hides metadata (e.g., time-on-task, resource logs). Compliance data are collected separately and isolated from raters. Statistical analyses follow a pre-registered analysis plan on a locked dataset, with group masking maintained until primary results are finalized; sensitivity/subgroup analyses adhere to the same masking. Maintaining and breaking the blind: Role-based access and audit trails ensure separation between scoring materials and allocation. Unblinding for serious deviations or safety reasons follows SOP with PI and data manager approval, documenting rationale and timing. Global unblinding occurs after study completion and archiving. |
