Improving ECG Services at a Children’s Hospital: Implementation of a Digital ECG System

Abstract

Background.The use of digital ECG software and services is becoming common. We hypothesized that the introduction of a completely digital ECG system would increase the volume of ECGs interpreted at our children’s hospital.Methods.As part of a hospital wide quality improvement initiative, a digital ECG service (MUSE, GE) was implemented at the Children’s Hospital at Montefiore in June 2012. The total volume of ECGs performed in the first 6 months of the digital ECG era was compared to 18 months of the predigital era. Predigital and postdigital data were compared viat-tests.Results.The mean ECGs interpreted per month were 53 ± 16 in the predigital era and 216 ± 37 in the postdigital era (p<0.001), a fourfold increase in ECG volume after introduction of the digital system. There was no significant change in inpatient or outpatient service volume during that time. The mean billing time decreased from 21 ± 27 days in the postdigital era to 12 ± 5 days in the postdigital era (p<0.001).Conclusion.Implementation of a digital ECG system increased the volume of ECGs officially interpreted and reported.
