Hospital Based Continuous Patient Monitoring System

April 30, 2026 updated by: Hassan Ghomrawi, University of Alabama at Birmingham

Implementing a Hospital-based Continuous Patient Monitoring System Using Consumer Wearable Devices in Ghana

In Ghana, and many other low and middle income countries in Africa, manual vital signs monitoring is the prevalent mode of vital signs monitoring because continuous bedside monitors are non-functional. This lack of continuous vital signs monitoring may result in missed opportunities to catch physiologic deterioration.

The investigators propose to develop a dashboard that is based on the Garmin Venu 3, a consumer wearable device that reliably measures heart rate, SPO2, and respiratory rate, as an alternative to bedside monitors in hospitals in Ghana.

Study Overview

Detailed Description

Vital sign (VS) monitoring is a universal tool used to assess patients' basic physiologic status, primarily to detect physiologic deterioration indicative of clinically meaningful events. Physiologic deterioration occurs relatively commonly in trauma and postoperative patient populations. In most high-income countries (HIC), such patients are therefore monitored by automated, continuous, bedside VS systems, while, in many low-and middle-income countries (LMIC), manual, intermittent (from every 15 minutes to every 6 hours) VS monitoring is still widely employed.

The investigators propose to further refine and scale up a CONsumer-grade wearable monitoring System to improve Outcomes in Low resource settings (CONSOL) in Ghana. CONSOL is a CWD based platform, developed by the MPIs, that collects and displays in near real time, HR, RR, and SpO2, with snapshots of the past 1 minute, and 1, 4, and 24 hours, viewable on an tabet or smartphone. The investigators propose to evaluate the use of CONSOL for VS monitoring of (a) pediatric trauma patients in the Emergency Department (ED) and (b) pediatric postoperative appendicitis patients on a surgical unit, given higher risk of physiologic deterioration indicative of clinically meaningful events in these patient populations, and because pediatric patients are often more limited, than adults, in their ability to communicate about signs and symptoms.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in heart rate with CONSOL compared to pre-CONSOL implementation
Time Frame: During the intervention (vital sign monitoring using the Garmin Venu 3)

The investigators will implement CONSOL and record the abnormal vital signs indicative of clinically meaningful events in the CONSOL group. The investigators will then compare the number of abnormal vital signs detected in the CONSOL group to that of the group of patient before CONSOL is implemented. The investigators will match the 2 groups on time period (e.g., CONSOL group recruited in 6-month period with pre-CONSOL group in the 6 months prior CONSOL.

Vital sign measured is heart rate. Abnormal vital sign cutoffs are listed below:

Heart Rate (beats/minute) 1-4 years old < 60 or >120 5-12 years old <60 or >110 13-18 years old <60 or >100

During the intervention (vital sign monitoring using the Garmin Venu 3)
Change in respiratory rate with CONSOL compared to pre-CONSOL implementation
Time Frame: During the intervention (vital sign monitoring using the Garmin Venu 3)

The investigators will implement CONSOL and record the abnormal vital signs indicative of clinically meaningful events in the CONSOL group. The investigators will then compare the number of abnormal vital signs detected in the CONSOL group to that of the group of patient before CONSOL is implemented. The investigators will match the 2 groups on time period (e.g., CONSOL group recruited in 6-month period with pre-CONSOL group in the 6 months prior CONSOL.

Vital sign measured respiratory rate. Abnormal vital sign cutoffs are listed below:

Respiratory Rate (breaths/minute) 1-4 years old <20 or >30 5-12 years old <16 or >20 13-18 years old <12 or >16

During the intervention (vital sign monitoring using the Garmin Venu 3)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in time to detection of abnormal heart rate using CONSOL
Time Frame: During the intervention (vital sign monitoring using the Garmin Venu 3)

Change in time to detection of abnormal heart rate (HR) will be estimated by assessing detection of abnormal HR in intervals of 15 minutes up to 6 hours (usual care intervals of manual VS measurement). Since CONSOL will be implemented in addition to usual care manual HR measurement, abnormal HR detected by CONSOL can be compared to abnormal HR detected by manual measurement at each interval.

Abnormal heart rate cutoffs are listed below:

Heart Rate (beats/minute) 1-4 years old < 60 or >120 5-12 years old <60 or >110 13-18 years old <60 or >100

During the intervention (vital sign monitoring using the Garmin Venu 3)
Change in time to detection of abnormal SPO2 using CONSOL
Time Frame: During the intervention (vital sign monitoring using the Garmin Venu 3)

Change in time to detection of abnormal SPO2 will be estimated by assessing detection of abnormal SPO2 in intervals of 15 minutes up to 6 hours (usual care intervals of manual VS measurement). Since CONSOL will be implemented in addition to usual care manual SPO2 measurement, abnormal SPO2 detected by CONSOL can be compared to abnormal SPO2 detected by manual measurement at each interval.

Abnormal SPO2, cutoffs are listed below:

SpO2 (%) <92%

During the intervention (vital sign monitoring using the Garmin Venu 3)
Change in time to detection of abnormal respiratory rate using CONSOL
Time Frame: During the intervention (vital sign monitoring using the Garmin Venu 3)

Change in time to detection of abnormal respiratory rate (RR) will be estimated by assessing detection of abnormal RR in intervals of 15 minutes up to 6 hours (usual care intervals of manual RR measurement). Since CONSOL will be implemented in addition to usual care manual RR measurement, abnormal RR detected by CONSOL can be compared to abnormal RR detected by manual measurement at each interval.

Abnormal respiratory rate cutoffs are listed below:

Respiratory Rate (breaths/minute) 1-4 years old <20 or >30 5-12 years old <16 or >20 13-18 years old <12 or >16
