Why These Calculators Use Indian & International Guidelines

Many standard medical calculators use Western or WHO cutoffs that are not always appropriate for all clinical settings. The BMI calculator uses Indian-specific thresholds (overweight ≥23, obese ≥25) because Indians develop metabolic disease at lower BMI values. Rabies PEP follows the 4-dose Essen regimen per NCDC India. Obstetric tools follow FOGSI and DIPSI protocols. Emergency scoring tools — CURB-65, NEWS2, GCS, and Wells Score — follow BTS, RCP, and NICE guidelines, which are internationally validated and widely used in Indian tertiary care settings.
