The Feasibility, Acceptability and Clinical Utility of a New Remote-mobile Technology Intervention (ASARM) for CFS/ME in a Paediatric Population

This study aims to improve on the delivery of treatment for people with Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME). People with CFS/ME have low energy. This interferes with doing everyday activities and has a major impact on quality of life. Energy management is a key aspect of treatment and involves patients building up their energy levels gradually. Their health professional finds out how much energy the patient uses daily so they can prescribe how much activity and rest is right for the patient. The prescription is adjusted throughout treatment. Over time, the patient learns the best way to "spend" and "preserve" energy. To begin treatment, patients record their activity levels on paper over a few weeks. Records need to be accurate, but this is often difficult because of problems with memory, concentration or low energy and pain.

We have recently developed a new technology called ASARM ("Advanced Sleep Rest Activity and Rest Management") that records activity levels electronically and checks whether they match the activity prescription. The ASARM device is worn on the patient's wrist. It measures sleep, activity and rest, and has an electronic diary (a smartphone app) for recording daily activities. The health professional has remote access to the information and uses the app to change the prescription. This study will investigate if ASARM is (i) acceptable to patients; (ii) a good way to deliver Cognitive Behavioural therapy CBT treatment; (iii) able to improve their symptoms. Patients and clinicians will gain experience of ASARM for a short time, and we will analyse their data. Our findings will help us develop ASARM so that it can be used in routine care of CFS/ME patients.

Standard practice is for patients to use pen and paper diaries to capture the initial "baseline" of sleep rest and activity. However, this can take several weeks to determine, relies on excellent adherence as well as the subjective recording of information that is sometimes hard to capture. Filling in the diaries can also place extra demands on energy and memory in patients and compromise treatment, particularly in the early stages of care, which can be characterized by feelings of hopelessness and disempowerment. Similarly, the number of trips to the clinic to discuss the diaries places particular demands on the energy resources of this patient group. ASARM's clinical impact therefore is to increase treatment adherence and treatment efficacy, to reduce the number of clinic visits for patients, as well as speeding up the processing of "diary" information for clinicians for monitoring progress and adapting treatment plans. ASARM will improve both the health of patients and reduce costs in running services by making treatments more accessible and reduce the number of appointments that will need to be offered.

There are two groups of patients who will use ASARM as part of their treatment, the "mid-treatment group" and the "start of treatment group". Both groups will receive the standard CBT treatment in the clinic, however they will be provided with the ASARM equipment in addition to this. Data will also be collected from the clinical records of 20 patients who have been previously treated with the standard treatment in the Manchester CFS/ME Service for Children \& Young People, referred to as the "case file audit" data. Finally there will be a focus group made up of one clinician from the service, two clinicians from other similar services, the researcher, and three past or present patients who have received treatment in the service.

Start of treatment Group:

Nine newly presenting patients will be assessed with the "gold-standard" fatigue outcome measures and then receive ASARM administered treatment for 10 weeks (in "baseline" for 2 weeks and "prescription" mode over an 8 week period). Patients will then revert to treatment as usual. On completion of ASARM treatment, information on how the patient experienced the paper diaries versus ASARM will be explored, and their clinical measures and ASARM activity diary data will also be assessed

Mid-treatment group:

Six patients who have just completed 6 sessions at the Manchester CFS/ME Service for Children \& Young People will be recruited. Each will be provided with ASARM treatment for 6 weeks. Clinicians from the CFS/ME Service will then deliver continued treatment and administer ASARM in "baseline" for 2 weeks and "prescription" mode over the next 4 weeks. They will then return to treatment as usual within the service. After completing the ASARM treatment, information on how the patient differentially experienced the paper diaries versus ASARM will be collected using the acceptability questionnaires, and their clinical outcomes will be assessed with the "gold-standard" fatigue outcome measures along with their rest, sleep and activity data from ASARM. The activity diary data and clinical data contained in these patient's case files before ASARM treatment will also be collected (see below for a more detailed overview).

"Case file audit" data:

To provide comparative baseline data for general treatment response, we will audit pre-treatment and post-treatment clinical data on the regular "gold standard" clinical measures package described in the "endpoints" section, as these are the outcome measures routinely used in the clinic. This information will be extracted from the records of 20 consecutive existing patients receiving treatment as usual i.e. patients who have used paper activity records. Their treatment duration will be dictated by the length of time a first post-treatment data set is available in the clinical case file, and that is closest to 10 weeks.

Focus groups The focus group will be formed and asked to review ASARM through description and demonstration. Feedback used for advising on the clinical protocol and for potential refinements to be made to the system in the future. When a draft version of the treatment manual is developed the Focus group meets to review this and suggest any changes necessary. When all patients have completed treatment, all clinician participants in the service who have had patients use ASARM form a focus group to explore their experiences and consider how ASARM data compares with TAU patients.
