# AI为eGFR <30 mL/min/1.73m²的患者开具'CMP + 对比剂额外采血管'，遗漏肾内科会诊

## 根因

AI将'对比剂额外采血管'误解为增强CT准备的常规实验室检查，实际上在严重肾功能不全患者中应触发肾内科会诊以评估对比剂肾病风险。

## 解决方案

1. ```
   Before any contrast study, check the patient's most recent eGFR (within 7 days). If eGFR <30 mL/min/1.73m², place a nephrology consult order and hold contrast pending consult recommendation. Use the hospital's contrast safety checklist (e.g., 'ContrastCheck' in Epic) to trigger automatic consult.
   ```
2. ```
   Implement a CDS (Clinical Decision Support) rule in the EHR: when 'contrast extra blood tube' is ordered for a patient with eGFR <30, auto-populate a nephrology consult order and display a warning: 'Contrast-induced nephropathy risk — consult nephrology before proceeding.'
   ```
3. ```
   For stat cases (e.g., suspected pulmonary embolism), administer IV fluids (0.9% NaCl at 1 mL/kg/h for 12h pre and post) and document nephrology notification as a verbal order, then follow up within 24h.
   ```

## 无效尝试

- **** — Assuming the 'extra tube' order is just a normal lab request and proceeding with contrast administration without renal function review. (85% 失败率)
- **** — Ordering a stat nephrology consult via pager without first verifying the patient's recent eGFR trend, causing delayed imaging. (60% 失败率)
- **** — Flagging the order as a 'lab error' and canceling it, then reordering the same without nephrology input. (75% 失败率)
