Summary

A prospective, single center, single arm phase 2 cohort feasibility study of the OURA ring in adult MDS patients. Patients with MDS will wear the OURA ring and upload biometrics weekly. Quality of life measures will be clinically evaluated and correlated with biometrics. We hypothesize that it will be feasible for MDS patients to wear the OURA ring 70% of the time for 3 months.

Detailed description

This is a single-centre feasibility study involving two groups of patients (transfusion-dependent MDS and non-transfusion dependent MDS), each enrolling 30 patients. Eligible patients who consent to the study will be provided with the OURA ring sizing kit to determine their ring size. Baseline characteristics will be collected, including the following information if available: * Patient demographics such as age, sex, history of cancer * MDS disease characteristics: date of diagnosis, IPSS and IPSS-R score, transfusion status, transfusion schedule, MDS specific treatment and concomittent medications * Laboratory data: hemoglobin, MCV, RDW, WBC, reticulocyte count, creatinine clearance, bilirubin, ALT, AST, LDH, ferritin The correctly sized OURA ring will be ordered and provided to the patient within 4 weeks during their Baseline visit at "week 0". At this time, technological assistance will be provided for correctly wearing the ring, installation of the OURA app to their smartphone, and teaching the patient how to sync the OURA ring to their device. During this visit, patients will have their first clinical assessment which includes a physical exam, vitals, height and weight, as well as the 4-metre walk test and the administration of the study questionnaires (ECOG score, clinical frailty score, QLQ-C30, QUALMS, EQ-5D, global fatigue scale, and the Lawton-Brody instrumental activity of daily living (IADL) scale. Patients will be given study forms to take home and complete based on the schedule listed in Appendix A. This includes a daily log of their global fatigue score, and a section for descriptive annotation of significant events in the day. Once every 7 days, patients will fill in the QLQ-C30, PROMIS-fatigue, QUALMS physical functioning subscale and synchronize the OURA ring data onto their smartphone. Patients will have monthly follow-up appointments at 1 and 2 months into the study. At these times, clinical events in the month will be reviewed, including whether they had transfusions, hospitalizations, or major health events. Patients' OURA ring data will be reviewed. Depending on OURA ring results, the physician involved may determine to order additional investigations or referrals (such as sleep clinic assessment or cardiology referrals). At month 3, patients will have their study exit visit. Data from the OURA ring app will be downloaded and a debrief will occur to qualitatively gauge the experience of a wearable device.

Interventions

Type	Name	Description
DEVICE	OURA Ring	The OURA ring (https://ouraring.com) is a light-weight wearable device in the form of a ring that has several microsensors enabling detection of heart rate, blood oxygen level, skin temperature, and movement. The OURA ring and application can synthesize the sensory data to generate physiologic information such as sleep, activity level, resting heart rate, heart rate variability, respiratory rate, and more. The OURA ring is water resistant and has up to 5-7 days of battery life and can be fully charged in 20-80 minutes. It communicates with the OURA app and commonly used Smartphone health apps via Bluetooth connectivity with automatic syncing every week.
