Objective. To test the model of centralized collection and analysis of electrocardiograms (ECG) obtained at the primary care level using telemedicine technologies.
Materials and methods. The model was tested as part of a single-center pilot project held at Moscow State Budgetary Healthcare Institution Consulting and Diagnostic Polyclinic No. 121 of the Moscow Healthcare Department. At the first stage, 14,811 ECGs were recorded on thermal paper using analog devices (analog, A-ECG); at the second stage, 12,776 ECGs were obtained using digital devices and stored in the information system (tele-ECG, T-ECG). Research methods: timing for 60 ECG, comparative economic analysis.
Results. Centralization of the ECG reporting resulted in a significant increase in the total duration of the study stages from 180.0 ± 19.3 to 192.0 ± 13.1 sec, p = 0.0056. This is due to significantly more time required to enter patient data into the software when performing T-ECG as compared to A-ECG (p < 0.0001). At the same time, time savings due to centralization were shown at the stages of report preparation and sending (7.0 ± 2.2 sec for T-ECG vs 32.0 ± 3.7 sec for A-ECG; p < 0.0001) as well as the documentation completion (62.0 ± 5.3 sec for T-ECG vs 78.0 ± 7.0 sec for A-ECG, p < 0.0001). The study revealed a significant decrease in the total duration of ECG reporting (202.0 ± 24.0 sec for A-ECG vs 81.0 ± 7.6 sec for T-ECG, p < 0.001), with the greatest time savings for the radiologist when compiling a conclusion (113.0 ± 21.5 sec for A-ECG vs 15.0 ± 3.4 sec for T-ECG, p < 0.001). The use of T-ECG resulted in the total budget savings of 63,880 rubles.
Conclusion. The introduction of T-ECG in a city polyclinic with an extensive branch network resulted in the reduction of reporting time by 60.5%, reduction of the time between the ECG recording and result generation and entering it into the outpatient medical record form 2–5 to 1 working day, as well as the reduction of financial costs by 91.7%.
