NeoCardioLab: A Digital Platform for Neonatal Hemodynamics Education.

Abstract

Introduction: Targeted neonatal echocardiography and neonatal hemodynamics are increasingly integrated into neonatal intensive care practice. However, access to structured, standardized educational resources and reference tools remains variable across settings. We aimed to describe the global reach, patterns of utilization, and perceived educational value of NeoCardioLab, a digital platform designed for neonatal hemodynamics education and support.

Methods: We conducted a descriptive, mixed-methods study combining retrospective analysis of anonymized usage data from January 2019 to June 2025 with a cross-sectional anonymous online survey conducted from December 2024 to July 2025. Data sources included Google Analytics, App Store Connect, Calconic, and YouTube analytics. Survey responses captured user demographics, utilization patterns, and perceived educational value.

Results: NeoCardioLab reached 98,004 active users across 203 countries between April 2022 and June 2025, with 342,911 page views and 5,861 mobile application downloads. English (75%), Spanish (6%), and French (5%) were the most common user languages from browser settings. Calculator tools were accessed 1,951 times over a 12-month period. Among 128 survey respondents (59% neonatologists), 84% reported increased confidence in neonatal hemodynamics, and perceived usefulness was noted for modules on pulmonary hypertension, congenital heart disease, and congenital diaphragmatic hernia. Reported impacts reflect self-perceived influence on knowledge and practice.

Conclusions: Our results suggest that NeoCardioLab has broad global reach and sustained user engagement as an open-access digital platform for neonatal hemodynamics. These findings support a potential role as a complementary educational resource and knowledge translation tool across diverse educational settings in neonatology.
