BACKGROUND: Different institutions use different grading systems for hereditary haemorrhagic telangiectasia (HHT)-associated epistaxis. It is important to have a universal, standardized grading system to compare and evaluate the effectiveness of different treatment options. We introduced the “Intensity, Frequency and need for Blood Transfusion” (IFT) grading system for HHT-associated epistaxis in 2008. Hoag et al. proposed the “Epistaxis Severity Score” (ESS) for the International HHT foundation in 2010. This study aimed to evaluate the potential correlation between the ESS and IFT grading systems.
METHODS: The study included 354 simultaneous reports using the IFT and ESS from 106 patients. The correlation between the ESS,
IFT and haemoglobin levels was measured using Pearson’s correlation coefficient. The ESS and IFT were scored simultaneously by the patient and doctor in 48 cases to evaluate if there was a discrepancy in the scoring applied by either set of responders.
RESULTS: The measured correlation between the two grading systems was good (0.75). The grade of epistaxis reported by patients
and doctors respectively showed no significant difference. Both the IFT and ESS grading systems correlate significantly to the
haemoglobin level.
CONCLUSIONS: Both the IFT and ESS scores correlate to each other, and their results are comparable. Whether the IFT or ESS scoring
was performed by the patient or doctor had no significant impact.
