Insights
Mobile cloud-based 12-lead electrocardiogram (MC-ECG) systems did not significantly reduce first-medical-contact-to-balloon times for ST-segment elevation myocardial infarction (STEMI) patients. However, MC-ECG use was associated with a significantly shorter hospital stay.
Area of Science:
- Cardiology
- Medical Technology
- Emergency Medicine
Background:
- Delay in reperfusion therapy increases mortality in ST-segment elevation myocardial infarction (STEMI).
- Guidelines recommend a first-medical-contact-to-balloon (FMCTB) time of under 90 minutes.
- Mobile cloud-based 12-lead electrocardiogram (MC-ECG) systems may improve STEMI care, particularly in rural settings.
Purpose of the Study:
- To evaluate the impact of an MC-ECG transmission system on FMCTB time in STEMI patients.
- To assess the effect of MC-ECG system use on hospital length of stay for STEMI patients.
Main Methods:
- A comparative study involving 48 STEMI patients transported via emergency medical services.
- Patients were divided into two groups: those using the MC-ECG system (n=23) and those using the conventional ECG method (n=25).
- Data collected included FMCTB time and length of hospital stay.
Main Results:
- No significant difference in FMCTB time was observed between the MC-ECG group (72.0 min) and the Conventional group (80.0 min) (p=0.77).
- The MC-ECG group had a significantly shorter length of hospital stay (12.0 days) compared to the Conventional group (16.0 days) (p=0.039).
- Logistic regression indicated that non-use of MC-ECG was associated with an increased risk of a hospital stay exceeding 15 days (adjusted OR=0.08, p=0.0098).
Conclusions:
- The MC-ECG system did not significantly shorten FMCTB times for STEMI patients.
- Utilizing the MC-ECG system resulted in a significant reduction in the length of hospital stay for STEMI patients.
- MC-ECG technology shows promise in improving patient outcomes by reducing hospitalization duration.
Abstract:
Backgroundand Objectives: Delay of reperfusion therapy is related to high mortality in cases of ST-segment elevation myocardial infarction (STEMI). Guidelines emphasize that the first-medical-contact-to-balloon (FMCTB) time should be within 90 min. A mobile cloud-based 12-lead electrocardiogram (MC-ECG) transmission system might be useful in such cases, especially in rural areas. Materials and Methods: From April 2019 to June 2021, both an MC-ECG transmission system and the conventional method in which a physician checks the ECG in a hospital (Conventional) were used for transport by emergency medical services in Shin-Yukuhashi Hospital, Fukuoka, Japan. During this period, 8684 consecutive patients were transported to this hospital. Among them, we investigated 48 STEMI patients. The MC-ECG group (n = 23) and the Conventional group (n = 25) were enrolled. Results: There was no significant difference in FMCTB time between the MC-ECG and Conventional groups (MC-ECG: 72.0 (60.5-107) min vs. Conventional: 80.0 (63.0-92.0) min, p = 0.77). The length of hospital stay in the MC-ECG group was significantly shorter than that in the Conventional group (12.0 (10.0-15.0) days vs. 16.0 (12.0-19.0) days, p = 0.039). The logistic regression model showed that patients' non-use of MC-ECG was associated with a risk of more than 15-day length of hospital stay with an adjusted odd ratio of 0.08 (95% CI: 0.013-0.55, p = 0.0098). Conclusions: Using the MC-ECG, the length of hospital stay in patients with STEMI was significantly reduced.
