[Clinical significance of ITP-BAT bleeding grading system for patients with immune thrombocytopenia].

OBJECTIVE: To explore the clinical significance, reliability and responsiveness of ITPBAT bleeding grading system for patients with immune thrombocytopenia (ITP). METHODS: One hundred and eighty-three patients with ITP were assessed by using of ITP-BAT bleeding grading system. Test-retest reliability, responsiveness of ITP-BAT bleeding grading system and association between bleeding grades and platelet counts, age, gender, disease stage were analyzed. RESULTS: Bleeding degree of ITP patients and the platelet count were negatively correlated (r=- 0.744, P 0.05 and χ²=3.411, P>0.05). Bleeding grades before and after treatment had more significant difference(Z=-6.61, P<0.01). Scoring consistency of two doctors was 66.1% (κ=0.561), and scoring consistency of the same doctor was 94.7% (κ=0.874). CONCLUSION: ITP-BAT bleeding grading system in China has good validity and responsiveness, closely related to clinical indicators. It is sensitive to the variation of the hemorrhage in patients. ITP-BAT could be used as a reference index of the treatment, and also be used as an observation index of curative effect.
