📋 KPI Tracking

The conclusion_remarks table enables powerful analytics:

1. AI Adoption Rate

SELECT 
  COUNT(CASE WHEN ai_generated_remark IS NOT NULL THEN 1 END) as ai_generated,
  COUNT(*) as total,
  ROUND(COUNT(CASE WHEN ai_generated_remark IS NOT NULL THEN 1 END)::DECIMAL / COUNT(*) * 100, 2) as adoption_rate
FROM conclusion_remarks
WHERE finalized_at IS NOT NULL;

2. Edit Frequency

SELECT 
  COUNT(CASE WHEN is_edited = true THEN 1 END) as edited,
  COUNT(*) as total,
  AVG(edit_count) as avg_edits_per_conclusion
FROM conclusion_remarks;

3. Average Confidence Score

SELECT 
  AVG(ai_confidence_score) as avg_confidence,
  MIN(ai_confidence_score) as min_confidence,
  MAX(ai_confidence_score) as max_confidence
FROM conclusion_remarks
WHERE ai_generated_remark IS NOT NULL;

4. Conclusion Length Analysis

SELECT 
  AVG(LENGTH(final_remark)) as avg_length,
  MAX(LENGTH(final_remark)) as max_length,
  MIN(LENGTH(final_remark)) as min_length
FROM conclusion_remarks
WHERE final_remark IS NOT NULL;

5. Provider Usage

SELECT 
  ai_model_used,
  COUNT(*) as usage_count,
  AVG(ai_confidence_score) as avg_confidence
FROM conclusion_remarks
WHERE ai_model_used IS NOT NULL
GROUP BY ai_model_used;
