The National Institute for Health and Care Excellence (NICE) describe “ post COVID-19 syndrome” or “Long COVID” as a set of persistent physical, cognitive and/or psychological symptoms that continue for more than 12 weeks after illness and which are not explained by an alternative diagnosis. These symptoms are experienced not only by patients discharged from hospital but also those in the community who did not require inpatient care. To support the recovery of this group of people, a unique integrated rehabilitation pathway was developed following extensive service evaluations by Leeds Primary Care Services, Leeds Community Healthcare NHS Trust and Leeds Teaching Hospital NHS Trust. The pathway aligns itself to the NHS England “Five-point plan” to embed post-COVID-19 syndrome assessment clinics across England, supporting the comprehensive medical assessment and rehabilitation intervention for patients in the community. The pathway was first of its kind to be set up in the UK and comprises of a three-tier service model (level 1: specialist MDT service, level 2: community therapy teams and level 3: self-management). The MDT service brings together various disciplines with specialist skill sets to provide targeted individualized interventions using a specific core set of outcome measures including C19-YRS (Yorkshire Rehabilitation Scale). Community and primary care teams worldwide need such an integrated multidisciplinary comprehensive model of care to deal with the growing number of cases of post-COVID-19 syndrome effectively and in a timely manner.

Background: The C19-YRS is the literature's first condition-specific, validated scale for patient assessment and monitoring in Post-COVID-19 syndrome (PCS).The 22-item scale's subscales (scores) are symptom severity (0-100), functional disability (0-50), additional symptoms (0-60), and overall health (0-10).Objectives: This study aimed to test the scale's psychometric properties using Rasch analysis and modify the scale based on analysis findings, emerging information on essential PCS symptoms, and feedback from a working group of patients and professionals.Methods: Data from 370 PCS patients were assessed using a Rasch Measurement Theory framework to test model fit, local dependency, response category functioning, differential item functioning, targeting, reliability, and unidimensionality.The working group undertook iterative changes to the scale based on the psychometric results and including essential symptoms.Results: Symptom severity and functional disability subscales showed good targeting and reliability. Post hoc rescoring suggested that a 4-point response category structure would be more appropriate than an 11-point response for both subscales.Symptoms with binary responses were placed in the other symptoms subscale.The overall health single-item subscale remained unchanged. Conclusion:A 17-item C19-YRSm was developed with subscales (scores): symptom severity (0-30), functional disability (0-15), other symptoms (0-25), and overall health (0-10).

Background The underlying pathophysiology of post-coronavirus disease 2019 (long-COVID-19) syndrome remains unknown, but increased cardiometabolic demand and state of mitochondrial dysfunction have emerged as candidate mechanisms. Cardiovascular magnetic resonance (CMR) provides insight into pathophysiological mechanisms underlying cardiovascular disease and 31-phosphorus CMR spectroscopy (31P-CMRS) allows non-invasive assessment of the myocardial energetic state. The main aim of the study was to assess whether long COVID-19 syndrome is associated with abnormalities of myocardial structure, function, perfusion and energy metabolism. Methods Prospective case–control study. A total of 20 patients with a clinical diagnosis of long COVID-19 syndrome (seropositive) and no prior underlying cardiovascular disease (CVD) and 10 matching healthy controls underwent 31P-CMRS and CMR at 3T at a single time point. All patients had been symptomatic with acute COVID-19, but none required hospital admission. Results Between the long COVID-19 syndrome patients and matched contemporary healthy controls there were no differences in myocardial energetics (phosphocreatine to ATP ratio), in cardiac structure (biventricular volumes), function (biventricular ejection fractions, global longitudinal strain), tissue characterization (T1 mapping and late gadolinium enhancement) or perfusion (myocardial rest and stress blood flow, myocardial perfusion reserve). One patient with long COVID-19 syndrome showed subepicardial hyperenhancement on late gadolinium enhancement imaging compatible with prior myocarditis, but no accompanying abnormality in cardiac size, function, perfusion, extracellular volume fraction, native T1, T2 or cardiac energetics. Conclusions In this prospective case–control study, the overwhelming majority of patients with a clinical long COVID-19 syndrome with no prior CVD did not exhibit any abnormalities in myocardial energetics, structure, function, blood flow or tissue characteristics.

Long COVID (LC) symptoms can be long standing, diverse and debilitating; comprehensive multidisciplinary rehabilitation programs are required to address this. A 10-week LC Virtual Rehabilitation Program (VRP) was developed to provide early education and self-management techniques to address the main symptoms of LC and was delivered to a group of persons with Long COVID (PwLC) online, facilitated by members of the multi-disciplinary rehabilitation team. This paper describes an evaluation of this VRP. Questionnaires completed by Healthcare Professionals (HCP) delivering the VRP were thematically analyzed to gain a priori themes and design semi-structured telephone interview questions for PwLC. Template analysis (TA) was used to analyze interview data. Routinely collected patient demographics and service data were also examined. Seventeen HCP survey responses were obtained and 38 PwLC telephone questionnaires were completed. The HCP interviews generated three a priori themes (1. Attendance and Availability, 2. Content, 3. Use of Digital Technology). TA was applied and three further themes emerged from the combined HCP and PwLC responses (4. Group Dynamics, 5. Individual Factors, 6. Internal Change). Key outcomes demonstrated that: the VRP was highly valued; digital delivery enabled self-management; barriers to attendance included work/life balance, use of technology, health inequalities; and LC was poorly understood by employers. Recommendations are provided for the design of VRPs for LC.

Background: The C19-YRS was the first validated scale reported in the literature for patient assessment and monitoring in Long Covid or Post-COVID syndrome. The 22-item scale contains four subscales measuring symptom severity, functional disability, overall health and additional symptoms. Objectives: This study aimed to modify and refine the scale based on psychometric properties, emerging evidence on additional Long Covid symptoms, and feedback from a working group of patients and healthcare professionals. Methods: Data were collected from 370 patients who completed the C19-YRS scale in a community Long COVID service. The psychometric properties of the Symptom Severity and Functional Disability subscales were assessed using a Rasch Measurement Theory framework, where all individual scale items were assessed for model fit, local dependency, response category functioning and differential item functioning (DIF) by age group and sex. Additionally, the subscales were assessed for targeting, reliability and unidimensionality. The overall health subscale is a single item, and the additional symptoms subscale is not intended to be summed, therefore neither is appropriate for Rasch analyses. Psychometric results and implications were relayed back to the working group for discussion, alongside clinical evidence of emerging and relevant symptoms not covered by the original C19-YRS. Results: Rasch analysis revealed promising psychometric properties of the symptom severity and functional disability subscales, with both displaying good targeting and reliability, although some individual measurement anomalies were noted. The original 0-10 item response category structure did not operate as intended for both the subscales. Post-hoc rescoring suggested that a 4-point response category structure would be more appropriate for both the subscales, and this aligned with patient feedback. This scoring change was implemented, alongside changes in the item composition of the symptom severity and additional symptoms subscales. The functional disability item set, and the overall health single-item subscale remained unchanged. Conclusion: A modified version of the C19-YRS was developed based on a combination of psychometric evidence, clinical relevance of the content and feedback from the working group (comprising patients and healthcare professionals). Future studies including NIHR funded LOCOMOTION study will undertake large-scale, multi-centre validation of the modified C19-YRS.
