EFM Guide is a non-commercial quick-reference app for medical trainees (not the lay public). It puts at your fingertips the approach, nomenclature, and management recommendations from the guidelines on electronic fetal monitoring (EFM) from 2008, 2009, and 2010. Each EFM finding and tracing is defined and explained with pictures. Management responses for findings and category interpretations are presented. And the systematic approach to EFM evaluation is reviewed. This app is written and intended for resident & student physician trainees, for nursing and midwifery trainees, and for practicing clinicians. It answers questions such as the following: - what is moderate baseline fetal heart rate variability? - what are the differences between an early, variable, and late deceleration? - what qualifies as tachysystole? and how can I manage tachysystole? - if my patient is 31 weeks gestation, what counts as an acceleration? - what qualifies as category I, II, and III tracings, and what does each suggest clinically? - what are the elements of systematic EFM tracing evaluation? - how may I respond to a category II tracing? - what does sinusoidal pattern look like? This guide tries to faithfully present the NICHD material for quick effective reference and review, it does not present the judgment of the app's authors. As educators and clinicians, we are interested in feedback and we would be grateful for guidance on improving the tool.

Verdict

The call

The clearest difference is review sentiment: ACOG at 90% against EFM Guide's 50%. ACOG also leads on update cadence (every 3 months vs every 25 months) and rating (4.9 vs 4.5). EFM Guide's advantage is iOS requirement (13.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.
