Description of intervention(s) / exposure
PainChek® is an approved medical device in the form of a smart device App, which combines artificial intelligence and smart automation to identify and quantify pain in real time. The App has been validated and used for assessing pain in people with moderate to severe dementia. PainChek® works by using facial recognition technology and analysis to detect pain through facial muscle movements which indicate the presence of pain. The user then enters other observed pain cues (e.g. vocalisation, movements and behaviours) exhibited by the patient via a series of checklists, and the App automatically calculates a pain score and assigns a pain intensity. The App does not store any images of the patient and adheres to strict medical privacy and confidentiality legislation.

Design and setting: This study will be conducted with family carers using PainChek® to assist pain assessment and monitoring of their relatives. The implementation study will be undertaken with assistance of Dementia Support Australia (DSA) consultants. DSA consultants have been using PainChek® since September 2017.
Method: DSA consultants will first assess the client for pain using PainChek®. If pain is identified as a potential contributing factor to the client’s behavioural change issues, the DSA consultants will check the eligibility of the family carers and offer them the use of PainChek® via a shared care model as part of the study. If they are interested, DSA consultants will explain the study to them and provide them with a copy of the Participant Information Statements and Information Brochure. Having answered any questions, the interested family carers will then be asked to sign the consent form. Once the consent form is signed, DSA consultants need to photograph it and send a copy to the primary researcher via a prepaid self-addressed envelope. The DSA consultants will then assist the family carers in downloading the App and demonstrate how to use it. The family carers will also be provided with access to online training and support via PainChek Ltd (www.painchek.com) and the primary researcher.The duration of face to face training workshop provided to the family carers is 2.5 hour. At the end of the training duration the DSA consultants will provide the family carers with a survey to complete. Participants will be asked to complete and return the survey in the prepaid self-addressed envelope within 7 days.This survey is divided into three sections and it will not take more than 10-15 minutes. Section A includes 20 statements about users’ (Family carers) perceptions of the potential usefulness of PainChek® as a means of assessing their loved one’s pain. These statements called ‘Health-ITUES’ are rated using a 5-point Likert scale (1= Strongly disagree and 5 = Strongly agree). The Health-ITUES consists of 20 items, with the higher scores correlating to higher technology usability. The 20-item scale consists of four subscales: (1) quality of work life, (2) perceived usefulness, (3) perceived ease of use, and (4) user control. Section B includes questions around the use of mobile technologies, and in Section C, there will be a number of questions about the participants’ age, gender, marital status, living arrangements, educational attainment, and in the case of those people with dementia the type of dementia (vascular, Alzheimer’s, frontotemporal, Lewy’s bodies, or mixed or unknown), degree of cognitive impairment, past medical history and medication history.
DSA consultants should recommend the family carers routinely assess (at least once a week) their loved one’s pain for 2 months whilst they are under the care of DSA. When the period of study is finished, family carers will again be asked to complete a short survey about their experience using the app.

Efficacy
Statistical methods / analysis
A sample size of 100 family carers of a relative with advanced dementia living at home is planned, which will allow detection of a small effect size of 0.30, with 80% power.
Data analysis: Quantitative data will be analysed using SPSS® V23 for Windows. Mean changes in the Health-ITUES scores (and other variables measured on a continuous scale) from pre to post implementation will be assessed for statistical significance using paired t-tests. A General Linear Model (GLM) will be used to identify if changes in the Health-ITUES scores may be associated with any other baseline or demographic variables (for example, changes in scores may be dependent on some baseline characteristics like pain score and may also differ according to age-group or gender). The Chi-square test will be used to identify significance of changes for dichotomous and categorical variables. Following convention, a p-value<0.05 will be taken to indicate a statistically significant association in all tests.

The clinical outcomes of using PainChek® include pain intensity which is assessed using PainChek® and behavioural symptoms severity that will be measured over time using Neuropsychiatric Inventory (NPI). Dementia Support Australia staff will measure the NPI for their clients at enrolment and discharge from the service.
Data analysis Since there will be only pairs of measurements for each participant (pre- and post- implementation), paired t-tests or Chi-square tests will be used to analyse changes in NPI, as appropriate. If the change in NPI score is found to be skewed, it will be subjected to a Box-Cox transformation prior to further analysis. This transformation acts to reduce skewness and bring the distribution closer to Normal, if possible. A General Linear Model (GLM) analysis will be used to identify whether any change in the NPI score is associated with any change in the PainChek® pain score over the same period, as well as any demographic or baseline characteristics of the participants. The characteristics which will be explored for possible association with change in NPI score will include: gender, age group, and documented chronic pain. Further, descriptive statistics (eg, mean, median) will be used to summarise the study participants (2A and 2B) and number of assessments conducted over time (pain scores), while inferential statistics (eg, CI) will be used to determine the level of significance.

Summary
Brief summary
The study focuses on applying a new assessment technology to better detect and monitor pain in older people with dementia living in the community. Elderly people, particularly those with dementia frequently suffer from painful conditions that are poorly treated. This is usually because dementia makes it difficult for people to remember and tell their doctors or family carers of how bad their pain is or in some cases when or where pain exists. Although, tools exit to assess pain in people with dementia, they are often subjective, manually based and subsequently underutilised. For this reason, this study aims to introduce PainChek® as an App for smart devices to assist family carers in assessing and monitoring pain of their relatives with moderate-severe dementia. It is hoped that the findings of this study will contribute to better pain management among this community-dwelling vulnerable population.
