ACTRN12622000193774 is one of the MATCH Project studies, and it is a proof of concept study trialling the MATCH App with people living with Dementia in the Community. The MATCH technology aims to integrate the Community and Residential Aged Care versions of the App with the biomarkers to recommend music.

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This study will be conducted in residential aged care (RAC) facilities in Victoria, Australia. We will fit consenting residents with wearable sensors and collect sensor data over a 10-day observation period (2 x 5-day observations separated by a 2-week break). Residents will be asked to wear the sensor devices for up to 8 hours per day.

During the first observation, the research team will observe participants to record episodes of agitation. During the second observation, the research team will continue to observe participants to record episodes of agitation. In addition, researchers will play manualised playlists of familiar/preferred and/or neutral music when a participant displays agitation symptoms and record any changes in agitation symptoms in response to the music. Five separate music playlists (5-10 songs per playlist, 1 playlist per day) will be curated by a music therapist prior to commencement of the study. Song choices will be based on information collected from the resident, their family and/or care staff regarding the resident’s familiar/preferred music, as well as any unpreferred music, specific songs to avoid, or past negative responses to music. Playlists will be created using Spotify and will be played on a wireless Bluetooth speaker. The playlists will be played in their entire duration unless participants respond negatively when the music is played (i.e. if agitation symptoms escalate or residents express wanting the music to stop), in which case the MATCH researcher will stop the music. Negative responses to music will also be recorded as adverse events. Data from this study will be used to determine the feasibility of using the different sensors from a clinical and technical perspective, as well as to develop the agitation detection algorithms by comparing clinical notes to sensor readings. Further, data from clinical notes, sensor readings and music metadata will be used to inform the development of an AI system to refine music recommendations to reduce agitation in residents living with dementia. The observation periods will be separated by a 2-week break in which researchers will develop models for agitation detection based on data from the first 5-day observation. Data from the second 5-day observation period will be used to test these models.

Outcomes
Primary outcome [1] 334116 0
Sensitivity and feasibility of sensor devices to capture biometric data that enables the prediction of agitation in residents with dementia, as well as changes in agitation levels in response to music, will be captured as a Composite Primary Outcome.

Biomarkers, such as respiratory rate, pulse rate and variability, motion-based activity, peripheral skin temp, electrical properties of skin, and galvanic skin response (perspiration), will be collected by the Empatica EmbracePlus sensor. Audio data (vocal patterns) will be collected by an audio sensor device (microphone) device worn by participating residents.

Clinical observations will be recorded using an adapted version of the Cohen Mansfield Agitation Inventory (CMAI). The CMAI includes 29 symptoms of agitation related to verbal, vocal, or motor activity. When the researcher observes an incident of agitation, the time of symptom onset and end will be recorded, as well as the types of behaviours observed and their severity based on perceived distress to the resident (mild, moderate or severe).
Timepoint [1] 334116 0
Biomarkers (physiology, motion and vocal patterns) will be continuously collected during the period of observation (2 x 5-day observations, <8 hrs per day)

Clinical observations of agitation symptoms will be recorded by an experienced clinician when agitation episodes occur during the observation period (2 x 5-day observations, <8 hours per day)
Secondary outcome [1] 419414 0
Reliability and safety of sensor devices: Any technical events (i.e. issues with the technical aspects of the sensors) will be recorded by researchers in a technical events log during the 10-day observation

Any adverse events that arise during the study will be recorded by researchers in an adverse event log.
Timepoint [1] 419414 0
Technical and adverse events will be recorded during the observation period (2 x 5-day observations)

Other design features
As this is a pilot feasibility study, we have no specific requirements regarding the number of participants. We aim to recruit up to 24 residents living with dementia. This sample size is deemed feasible from an implementation perspective and will provide sufficient data for further development, given monitoring will occur over a 10-day period (per participant).

Efficacy
Statistical methods / analysis
Each sensor unit will be configured to fire a heartbeat signal every 24 hours. The sensor heartbeat is a binary signal that varies between normal and abnormal, indicating the hardware status of the sensor. A software tool will be developed to examine the hardware status for all sensor units and alert research team about potential faulty sensors on a daily basis. Data sanity check will be performed to detect corrupt or inaccurate records from the collected dataset. As the first step of data sanity check, the percentage of missing values for each of the sensor units will be calculated. The sensor units with a missing value percentage over 5% will be dropped from further analysis.
An agitation detection algorithm will be developed based on the data gathered and formulated as a supervised learning task. A learning model will be trained to map the physiological, activity, and audio data to the occurrence of agitation observed by clinicians. This algorithm will build a hypothesis from a set of “labelled” instances (the training set with the corresponding estimated agitation levels, based on observations from the modified CMAI form), which then can be used to make predictions about future unlabelled instances (i.e., predict agitation levels). To reduce variability in the results, a k-fold cross-validation technique will be used to assess the classification. Effect sizes will be calculated for the baseline scores for NPI-NH and Cohen-Mansfield Agitation Inventory.
The agitation levels estimated by the agitation detection algorithm will be used to build our music recommender system. This music recommender system predicts a set of songs to reduce the agitation level of a given user (i.e., intervention). Reinforcement learning techniques will be used to reward the recommendation model when the predicted songs contribute to the intervention process (i.e., our model will learn which songs should and shouldn’t be recommended).
