Is there a difference to the social determinants of health for those who complete a COVID rehabilitation assessment compared to those who decline/ drop-out?

<bold>Background:</bold> Following the COVID pandemic, COVID Rehabilitation (CoR) was found to be beneficial, for those with ongoing symptoms (> 12 weeks), demonstrating improvements in fatigue, breathlessness, exercise capacity and cognition1. <bold>Aims:</bold> To understand the social determinants of health in individuals who completed CoR compared to those who declined or dropped out. <bold>Methods:</bold> Those who attended a CoR assessment between July 2020 and October 2023 were included in the analysis. Social determinants of health captured were: ethnicity, language, age, gender, social circumstances, marital status and number of self-reported comorbidities. <bold>Results:</bold> 862 individuals [520 (60%) female, White British (56%), mean (SD) age 55 (13) years] were included in the analysis. 395(46%) individuals completed CoR and 467 (54%) either declined or dropped out of the programme. There were no statistically significant differences across seven ethnic groups [p = 0.47], eight languages [p=0=.33], mean age [p=0.49], gender [p=.0.12], or marital status (six categories) [p=.0.93] for completion of CoR versus decliners/ drop-outs. However, there were significant differences in social circumstances (lives with spouse/partner, lives alone, lives with adults/children) between groups [P<0.01]. Comorbidities (categories 0, 1, 2 >/=3) were not different between group [p=0.07]. <bold>Conclusion:</bold> Ethnicity, language spoken, gender and age did not influence completion. People who live with spouse/partner had lower completion rates than other groups and may need additional support to complete CoR. Future work could explore the impact of social determinants on outcomes of CoR.
