# AI指示使用患者房间号或床位标签代替腕带条码标记输血前血样，导致试管内血液错误（WBIT）

## 根因

使用房间号或床位标签进行样本标识绕过了AABB标准要求的双人核对和条码扫描，导致标本标签错误，可能引起ABO不相容输血和致命性溶血反应。

## 解决方案

1. ```
   Use barcode wristband scanning at the bedside: scan patient wristband -> scan label -> apply label to tube. Two identifiers required (name + DOB or MRN). Verify with: `python -c "import hashlib; print('Scan patient wristband barcode, then scan blank label, then apply label at bedside. Confirm: name=' + input('Enter patient name: ') + ' DOB=' + input('Enter DOB: '))"`
   ```
2. ```
   Implement electronic positive patient identification (ePPID) system: use handheld device to scan wristband, print label at bedside, and apply immediately. Document: `Sample collected via ePPID at 14:30, wristband scanned, label printed and applied at bedside.`
   ```

## 无效尝试

- **** — Writing 'Room 302 Bed A' on the label because 'the nurse knows which patient it is' — does not meet AABB identification requirements; any misidentification leads to WBIT (85% 失败率)
- **** — Using a pre-printed label from the chart without verifying against the wristband — labels can be misplaced or belong to the wrong patient (70% 失败率)
- **** — Scanning the wristband but then hand-writing the label without barcode — hand-written labels are prone to transcription errors (60% 失败率)
