BPpercentiles

BPpercentiles is a powerful and comprehensive tool designed to assist healthcare professionals in calculating blood pressure percentiles and z-scores for children and adolescents aged 0 to 17.99 years. By entering the child’s age, date of visit, sex, systolic and diastolic blood pressure, and height, the app provides a detailed classification of the child's blood pressure status within seconds.

The app’s key feature is its ability to calculate percentiles and z-scores for systolic and diastolic blood pressure using two validated statistical methods:

1) LMS Method – Based on Flynn JT et al. "Clinical Practice Guideline for Screening and Management of High Blood Pressure in Children and Adolescents." (2017).
2) Quantile Regression Method – As described by Rosner B et al. "Determination of blood pressure percentiles in normal-weight children: Some methodological issues." (2008).

BPpercentiles goes beyond simple percentile calculations. It offers three hypertension classifications according to major international guidelines:

- The American Academy of Pediatrics (AAP)
- The European Society of Hypertension (ESH)
- The European Society of Cardiology (ESC)

Key Benefits and Features:
- User-Friendly and Free: Intuitive design enables quick data entry and instant results, optimizing time during consultations.
- Dual-Method Percentile Calculation: Assess blood pressure percentiles using both LMS and Rosner’s quantile regression methods for comprehensive and flexible evaluations.
- Triple Hypertension Classification: Compare hypertension classifications according to American Academy of Pediatrics (AAP), European Society of Hypertension (ESH), and European Society of Cardiology (ESC) guidelines, minimizing ambiguity and providing clearer diagnostic insights.
- Flexible Unit Support: Input height in cm, m, ft, or a combination of units.
- Outlier Detection: Instantly detect outliers based on height z-scores.
- Detailed Reporting: Generate comprehensive reports to facilitate discussions with parents and guide treatment decisions.

BPpercentiles is an indispensable tool for pediatricians, cardiologists, and healthcare providers who require fast, accurate, and evidence-based blood pressure evaluations. The app empowers clinicians to make informed decisions by integrating multiple perspectives into a single, streamlined platform.
