A Case for Unifying Accelerometry-Derived Movement Behaviors and Tests of Exercise Capacity for the Assessment of Relative Physical Activity Intensity.

Albert Einstein taught us that "everything is relative." People's experience of physical activity (PA) is no different, with "relativism" particularly pertinent to the perception of intensity. Markers of absolute and relative intensities of PA have different but complimentary utilities, with absolute intensity considered best for PA guideline adherence and relative intensity for personalized exercise prescription. Under the paradigm of exercise and PA as medicine, our Technical Note proposes a method of synchronizing accelerometry with the incremental shuttle walking test to facilitate description of the intensity of the free-living PA profile in absolute and relative terms. Our approach is able to generate and distinguish "can do" or "cannot do" (based on exercise capacity) and "does do" or "does not do" (based on relative intensity PA) classifications in a chronic respiratory disease population, facilitating the selection of potential appropriate individually tailored interventions. By synchronizing direct assessments of exercise capacity and PA, clearer insights into the intensity of PA performed during everyday life can be gleaned. We believe the next steps are as follows: (1) to determine the feasibility and effectiveness of using relative and absolute intensities in combination to personalize the approach, (2) to determine its sensitivity to change following interventions (eg, exercise-based rehabilitation), and (3) to explore the use of this approach in healthier populations and in other long-term conditions.

Public Use of the "Your COVID Recovery" Website Designed to Help Individuals Manage Their COVID-19 Recovery: Observational Study.

BACKGROUND: At the start of the COVID-19 pandemic, unprecedented pressure was placed on health care services globally. An opportunity to alleviate this pressure was to introduce a digital health platform that provided COVID-19-related advice and helped individuals understand and manage their COVID-19 symptoms. Therefore, in July 2020, the Your COVID Recovery website was launched by the National Health Service of England with the aim of creating a practical tool that provides advice and support to individuals recovering from COVID-19. The website includes information on many of the key COVID-19 symptoms. To date, public use of the Your COVID Recovery website and user behavior remain unknown. However, this information is likely to afford insight into the impact of the website and most commonly experienced COVID-19 symptoms. OBJECTIVE: This study aimed to evaluate public use of the Your COVID Recovery website, a digital health platform that provides support to individuals recovering from COVID-19, and determine user behavior during its first year of operation. METHODS: Google Analytics software that was integrated into the Your COVID Recovery website was used to assess website use and user behavior between July 31, 2020, and July 31, 2021. Variables that were tracked included the number of users, user country of residence, traffic source, number of page views, number of session views, and mean session duration. User data were compared to COVID-19 case data downloaded from the UK government's website. RESULTS: During the study period, 2,062,394 users accessed the Your COVID Recovery website. The majority of users were located in the United Kingdom (1,265,061/2,062,394, 61.30%) and accessed the website via a search engine (1,443,057/2,062,394, 69.97%). The number of daily website users (n=15,298) peaked on January 18, 2021, during the second wave of COVID-19 in the United Kingdom. The most frequently visited pages after the home page were for the following COVID-19 symptoms: Cough (n=550,190, 12.17%), Fatigue (n=432,421, 9.56%), Musculoskeletal pain (n=406,859, 9.00%), Taste and smell (n=270,599, 5.98%), and Breathlessness (n=203,136, 4.49%). The average session duration was 1 minute 13 seconds. CONCLUSIONS: A large cohort of individuals actively sought help with their COVID-19 recovery from the website, championing the potential of this tool to target an unmet health care need. User behavior demonstrated that individuals were primarily seeking advice on how to relieve and manage COVID-19 symptoms, especially symptoms of cough, fatigue, and musculoskeletal pain. COVID-19 rehabilitation programs should use the results of this study to ensure that the program content meets the needs of the post-COVID-19 population.

Early experiences of the Your COVID Recovery® digital programme for individuals with long COVID.

OBJECTIVES: To describe the early data from the Your COVID Recovery® digital programme and to explore the data collected from two embedded outcome measures. DESIGN: Observational. SETTING: Primary and secondary care (England-Online). PARTICIPANTS: 110 individuals completed the programme (68.1% female, 88.1% White British, age: 46.3 (10.8) years, weight: 86.5 (21.1) kg, height: 169.3 (10.0) cm). 47.2% of patients reported comorbidities. INTERVENTION: Following an assessment by a healthcare professional, individuals with long COVID were offered access to the Your COVID Recovery® digital programme. The programme comprises of four stages for the participants to progress through. Participants are encouraged to record severity of their symptoms and amount of activity they are doing on a symptom and an activity tracker. Resources and interactive material on managing symptoms of long COVID are available throughout each stage. PRIMARY OUTCOME MEASURES: Questionnaire (EuroQ0l 5-Dimension 5-Level (EQ-5D-5L) and the chronic obstructive pulmonary disease assessment test (CAT)) data were extracted from the site from 11 March 2021 until 9 November 2021. RESULTS: Participants were on the programme for 8.6 (4.3) weeks. There was a statistically significant increase in EQ-5D-5L visual analogue scale (VAS) score (pre=48.8 (19.5); post=59.9 (22.1); p<0.01). The EQ-5D-5L Index Value preintervention to postintervention did improve but not significantly (pre=0.5 (0.3); post=0.6 (0.3); p=0.09). CAT total score improved significantly preintervention to postintervention (pre=19.8 (7.2); post=15.6 (7.6); p<0.01). All CAT item scores significantly improved preintervention to postintervention (p<0.005), except the phlegm item score (p=0.168). DISCUSSION: This early data describes the impact of the Your COVID Recovery® digital programme on the first cohort of patients to complete the digital recovery programme. The outcome data are promising and should encourage uptake.
