Description of intervention(s) / exposure
Patients with suspected (control) or confirmed COVID-19 were studied for 12 months after diagnosis. The study involved physical (1-minute sit-to-stand test [1-STS]; grip strength) and PROM measures (Modified medical research council dyspnoea scale, Fatigue Severity Scale, Hospital Anxiety and Depression Scale, Impact of Events Scale, EQ-5D-5L) repeated at 3 time points in the year (3, 6 and 12 months) after attending a health facility in Perth, Western Australia. All participants completed study physical and survey assessments on the same day with remote (via video or phone) and face-to-face options available to reduce the patient burden and minimise transmission of infection. (Grip strength and oxygen saturation for the 1-STS were not collected if patients were assessed outside the hospital environment.) A research physiotherapist or trained research assistant conducted the assessments and each session took approximately 30-40 minutes. Data were collected prospectively from June 2020 and will be analysed retrospectively.

Diagnosis / Prognosis
Comparator / control treatment
Control patients were recruited after attending ambulatory clinics, ED or admitted to hospital with suspected COVID-19. They were recruited based on their attendance at the same time as COVID-19 confirmed patients. Control patients completed the same assessments as the COVID-19 positive participants.

Key exclusion criteria
Participant exclusion criteria:
Participants were excluded with preexisting neuromuscular disorders thought to affect the measures of physical function including previous cerebrovascular incidents, muscle or bony injury within the last three months, or pre-existing disorders such as Parkinson’s Disease; preexisting mental illness,; and, significant communication or cognitive impairment thought to affect responses to self-report measures.

Statistical methods / analysis
Statistical analysis
Descriptive summaries will include means ± SD or medians [interquartile ranges] for continuous data and frequency distributions for categorical data. Comparisons of patient baseline characteristics (gender, age, comorbidities) and clinical characteristic data by disease severity (mild or severe/critical) will be undertaken using parametric independent t-tests or oneway ANOVAs for normally distributed continuous data and non-parametric Mann-Whitney U or Kruskall-Wallis H tests for continuous data not confirmed to display a normal distribution and Chi-squared or Fisher’s Exact tests, as appropriate, for categorical data.

Associations of patient and clinical characteristic predictors with longitudinal in-hospital symptomatic and physical functioning outcomes (including 1STS, handgrip force) will be examined using generalised linear mixed models (GLMM) with random subject effects, adjusting for disease severity, length of stay in ICU and in hospital, and selected baseline (admission) characteristics. Associations of patient characteristic, clinical pathway and rehabilitation pathway predictors with post-discharge recovery trajectories (including 1STS, FSS, MMRC, EQ-5D-5L, HADS, IES-6 and clinical sequalae) will be examined using GLMM with random subject effects, adjusting for disease severity and selected baseline (discharge) characteristics. All models will be implemented as univariable and predictive multivariable models, with all covariates univariately significant at alpha=0.15 considered as candidate predictors in the multivariable models. Results will be summarised using estimated marginal means and 95% CI for continuous outcomes or odds ratios (OR) and 95% CI for categorical outcomes. Model fit will be assessed using residuals checking and cross-validation of models will be undertaken by splitting the dataset to form training and test sets if the sample is large. Missing data points in longitudinal data will be accounted for by the use of maximum likelihood estimation (MLE) methods in the models. Temporal outcomes including time to death and time to discharge in the in-hospital analysis and time to reach recovery milestones, defined according to EQ5D age and gender appropriate norms, in post-discharge analysis will be assessed using Kaplan-Meier survival probabilities and compared between relevant patient characteristic, clinical pathway and rehabilitation pathway predictors using Log rank tests. Effects of these predictors on temporal outcomes will be examined using Cox proportional hazards regression models, censoring at 12 months post-admission and adjusting for relevant baseline patient and clinical characteristics. Results will be summarised using hazard ratios (HR) and 95% CI. Sensitivity analyses will be performed on patients who are engaged in any other forms of exercise/wellbeing apps/activities and those who are not.
Stata MP version 16.0 (StataCorp LP, College Station, TX) will be used for data analysis. All hypotheses will be two-sided and significance will be set at alpha=0.05.

Summary
Brief summary
Project Summary
In the majority of cases coronavirus disease (COVID-19) people present with signs and symptoms of respiratory tract infection including fever, cough, fatigue, dyspnoea, and sputum production. Although the majority of COVID-19 cases have mild to moderate disease, approximately 15% will develop severe or critical disease that requires intensive medical management or admission to an intensive care unit (ICU). Medical management in ICU often includes use of sedation, neuromuscular blocking agents and prolonged mechanical ventilation. Given the nature of the disease process and the treatment required, those affected by severe COVID-19 infection are at risk of long-term sequelae that can potential to affect long-term health and wellbeing. These sequelae include symptoms such as fatigue and shortness of breath, ongoing weakness and reduced physical function due to ICU-acquired weakness (ICUAW) and impaired psychological function. It is essential to provide an in-depth multidimensional description of recovery trajectories during and following the acute phase of the disease from a symptom, physical and psychological perspective.
The main aim of this study will be to provide a multidimensional analysis of recovery in people with severe (or critical) COVID-19 during the first 12 months following diagnosis. Specific objectives are to: (i) document recovery trajectories during and following the acute phase of the disease from a symptom, physical and psychological perspective; and (ii) identify factors associated with prolonged recovery.
