Digital Voice Analysis as a Measure of Frailty and Distress. A Feasibility Study (DIVAN)
This study evaluates if it is possible to identify quantitative parameters from audio signals to describe the changes in patient's state in relation to frailty and distress.

Detailed Description
Frailty is a common clinical syndrome especially in older adults that carries an increased risk for poor health outcomes including falls, incident disability, hospitalization, and mortality.
The early detection of frailty is of importance in many patient populations to predict treatment outcomes, identify patient needs and coordinate efficient and meaningful care.
An electronic assessment of the degree of distress in patients, who are unable to report, would be important to be able to routinely and objectively identify suffering in these patients.
Digital voice analysis (DVA) gathers speech samples from individuals via different kinds of recording devices (smartphone, tablet, etc.) and examines a large variety of specific acoustic parameters such as for example frequency and voice quality features.
This study is to analyse the potential to evaluate distress and frailty through digital voice analysis.
On the contrary to the existing studies, it is intended to record audio and clinical evaluation data from the same subject multiple times during several weeks to be able to analyse temporal changes.
This will allow to not only perform inter-subject but as well intra-subject comparisons of changes in audio features with changes of the patient's wellbeing over time.
To make the patient speak as freely and relaxed as possible, the patient will describe different images.
Different features will be extracted from the audios and potential candidates for a larger patient study will be identified, if data quantity permits using machine learning algorithms.
Therefore this study evaluates if it is feasible to gather digital voice samples for voice analyses from cancer patients alongside conventional assessments for frailty (G8 questionnaire and distress (Distress Thermometer) to conduct first, preliminary analyses for identification of potential correlates between voice features and frailty or distress and between changes over time.

Design Details
Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
Cohort A: palliative care center
Patients from a palliative care center (Palliativzentrum Hildegard, Basel)
|
Speech test with synchronized audio and video recording.
The speaking exercises and the audio and video recording will be done using a tablet computer and an application developed in-house.
Freely available images showing different scenes will be integrated and displayed on the tablet to be described by the patient.
The goal is to have at least two and maximum four of them described with several sentences by each patient per session.
Parameters will be extracted from the patient's audio data to estimate the changes in distress and frailty.
The G8 screening tool consists of seven items dealing with food intake, weight loss, mobility, neuropsychological problem, body mass index, prescription drug, and self-perception of health, from the Mini-Nutritional Assessment (MNA) questionnaire and was developed specifically for elderly cancer patients.
The total G-8 score lies between 0 and 17.
A higher score indicates a better health status.
The distress thermometer (DT) is a measure of psychological distress in cancer patients.
The instrument is a self-reported tool using a 0-to-10 rating scale.

Cohort B: mid-size cancer center
Patients from a mid-size cancer center (Tumorzentrum Baselland)
|
Speech test with synchronized audio and video recording.
