The goal of this study is to measure the clinical impact and cost-effectiveness of a wireless vital signs monitor, neoGuard, for hospitalized newborns at a tertiary healthcare facility in Kenya. The main questions it aims to answer are:
The study will consist of an intervention group and a comparison group. Researchers will compare nurses' response time to patients in distress, newborn complication rates and treatment outcomes between the two groups.
This is an interrupted time series study conducted at the Moi Teaching and Referral Hospital (MTRH) neonatal ward between April 2022 and June 2023. Our study participants comprise of newborn patients admitted at MTRH during that period. The MTRH neonatal ward is arranged in 8 sub-units which comprise our comparison sub-groups. Newborns admitted from April-November 2022 comprise the pre-intervention arm and are not exposed to neoGuard, but receive existing standard-of-care vital sign monitoring.
In December 2022, neoGuard was installed in 4 sub-units (intervention group), while the remaining 4 sub-units (comparison group) continued to use standard-of-care monitoring.
The measurement of effectiveness will be performed at three levels: (1) device's ability to detect abnormal physiological signals and provide alerts/alarms that notify the nurses to check on a patient's status and; (2) alarms/alerts from level one that resulted in a necessary intervention being administered to the patient (valid alarms), versus all the alarms/alerts that did not necessitate an intervention (invalid alarms); (3) the month-to-month difference in newborn complication rates and treatment outcomes between the intervention group and comparison group.
Medical staff who interact with neoGuard will participate in user surveys at the end of the intervention period to capture user experience and perceptions on feasibility and sustainability.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Intervention Group | The intervention group consists of patients admitted to the 4 neonatal subunits where neoGuard was installed: the preterm units (category A and category B), and the high dependence units (HDU-1 and HDU-2). |
| |
| Comparison Group | The comparison group consists patients admitted 4 subunits where neoGuard was not installed: the neonatal intensive care unit (NICU), the KMC/category C room, the isolation room and the stable full-term room. These subunits will receive the standard-of-care/current practice, which consists of either a bedside cardiac monitor or intermittent monitoring every 3 hours using manual equipment such as hand-held pulse oximeters for pulse rate and oxygen saturation, digital axillary thermometers for temperature, and manual counting of breaths for respiratory rate. |

| neoGuard vital signs monitor | Device | The neoGuard device is a 4-in-1 wearable vital signs monitor developed by Neopenda, PBC (Chicago, Illinois). The system is designed to continuously measure temperature, pulse rate (PR), respiratory rate (RR) and blood oxygen saturation (SpO2). It contains two non-invasive sensors: an optical reflectance pulse oximeter and a digital temperature sensor. These sensors measure signals from the surface of the patient's skin, and algorithms within the device calculate the pulse rate, respiratory rate, SpO2 and temperature. The device is made of medical grade polyetherimide plastic and can be worn on the forehead through an adjustable band. The PR, RR, temperature and SpO2 data are collected, recorded and transmitted via Bluetooth Low Energy (BLE) to a tablet which can be placed within a range of 20-30 meter distance. The neoGuard technology has received CE mark certification and is also registered with the Kenya Pharmacy and Poisons Board (KPPB). |
| Measure | Description | Time Frame |
|---|---|---|
| Nurse's response time to patients in distress | The time elapsed (in seconds) between the neoGuard alarm being triggered (distress signal) and the nurse attending to the patient | Captured in real time through monitor logs, within a few seconds to minutes of the event |
| Percentage of actionable alarms | The overall proportion of alarms that are indicative of a true physiological change (distress signal) resulting in an intervention or treatment of the patient | Measured over a maximum period of 7 days for each patient |
| Measure | Description | Time Frame |
|---|---|---|
| Incidence of patient complications | Bi-weekly change in the incidence of patient complications | Through study completion, across 64 weeks |
| In-hospital mortality | Month-to-month change in the incidence of in-hospital mortality |
| Measure | Description | Time Frame |
|---|---|---|
| Qualitative feedback from health providers | Nurses will be surveyed about their experience and perceptions of the technology | Once, at study completion |
