2. Introduction – about the RETENTION
project
The primary goal of the RETENTION
project is to develop an integrated platform that gathers and analyses
health-related data flows, with further analysis of the day-by-day activities
of Heart Failure study participants in their home environment. Such continuous
data collection and processing will later provide the input for personalized
interventions that support the healthy and independent lives of the study
participants.
This collection will be performed by:
· Continuously monitoring
and collecting medical, clinical, physiological, behavioural, psychosocial, and
real-world data of patients.
· Analysing this data using
innovative model-driven big data analytics, statistical, artificial
intelligence and machine learning techniques.
· Detecting patterns in the
HF disease progress and the quality of life of patients.
· Cross checking and
validating them against clinical literature.
· Offering transparent,
explainable and verifiable decision-making capabilities that leverage the
evidence produced by the underlying data analysis.
This document is a user manual of the
RETENTION application, including a demo and how – to – use instructions. The application’s
main goal is to monitor (collect and present) a Cardiology patient’s
measurements while outside hospital care using standard, easily acquired
equipment. It should also be noted that RETENTION will abide by all principles
of GDPR including the principles of lawfulness, fairness and transparency,
purpose limitation and data minimization.
2.1. Study Pre-specified subgroup
analyses include
· The three patient categories:
o Heart Failure [HF],
o Left Ventricular Assist
Device [LVAD]
o and Heart Transplant [HT]
· Males and Females
· Patients with a hospitalization
less than three months from the enrolment
· Patients older than 60
years old
2.2. Data points used by the study
· Smartwatch (Heart rate,
Steps counter, Sleep analysis)
· Oximeter (Oxygen saturation)
· Pressure gauge (Blood
pressure) – excluding patients with LVAD
· Weight scales (Body
weight)
· Temperature (Manual entry)
· VAD (Manual entry)
The above devices send the collecting
data to a cell phone app via Bluetooth (BLE).
As an additional feature, a
questionnaire is embedded, giving doctors the ability to easily access patient symptoms.
This action should be completed at least once a week, on demand.
2.3. Extra Measurements -VAD
The following data will be
additionally collected for patients with VAD device installed:
· Controller parameters
· Alarms
· RPMs
· Power consumption
· Flow
· Pulsatility index
·
Driveline exit site evaluation (photographic evidence) as
early signs of infection

2.5. Alternative devices
· Application edge (mobile
device)
o Samsung A02s or A03s
·
Watch – Garmin

3. Daily Measurement intervals for the
application
3.1. Data collected by the application
from smart sensors and devices on a daily basis should be:

wearing the Smartwatch) (synching once a day – morning)
· Peripheral capillary
oxygen saturation (morning, evening)
· Sleep: deep and light
sleep phases, sleep interruptions (via the watch)

climbed, calories consumed (via the watch)
Warning
· Make sure you connect your phone/tablet to the internet at least

Ø The size of the air chamber of the cuff plays a role in the accuracy
of your measurements.
Ø
When you first
start measuring your blood pressure, the measurement should be taken on both
arms. If you find a difference of up to 1.5 millimetres
of mercury between the two hands, don’t worry. It is a common phenomenon. If
there is a bigger difference, inform your physician. For subsequent
measurements, use the arm that measures higher.

· Tap the ‘Measures’ icon
·
Tap ‘Database’
·
This screen will display a history of the user’s past
