At 6-month follow-up after hospitalisation due to COVID-19 disease, patients displayed a wide array of neurological symptoms, being fatigue (34%), memory/attention (31%), and sleep disorders (30%) the most frequent. Subjects reporting neurological symptoms were affected by more severe respiratory SARS-CoV-2 infection parameters during hospitalisation. At neurological examination, 37.4% of patients exhibited neurological abnormalities, being cognitive deficits (17.5%), hyposmia (15.7%) and postural tremor (13.8%) the most common. Patients with cognitive deficits at follow-up were comparable for age, sex and pre-admission comorbidities but experienced worse respiratory SARS-CoV-2 infection disease and longer hospitalisation. Conclusions: long term neurological manifestations after hospitalization due to COVID-19 infection affects one third of survivors. Multiple neurological abnormalities including mild cognitive impairment are associated with severity of respiratory SARS-CoV-2 infection.

6-month consequences of COVID-19 in patients discharged from hospital: a cohort study

At 6 months after acute infection, COVID-19 survivors were mainly troubled with fatigue or muscle weakness, sleep difficulties, and anxiety or depression. Patients who were more severely ill during their hospital stay had more severe impaired pulmonary diffusion capacities and abnormal chest imaging manifestations, and are the main target population for intervention of long-term recovery.

Abstract
Objectives: The epidemiology of post-COVID syndrome (PCS) is currently undefined. We quantified rates of organ-specific impairment following recovery from COVID-19 hospitalisation compared with those in a matched control group, and how the rate ratio (RR) varies by age, sex, and ethnicity.

Design: Observational, retrospective, matched cohort study.
Setting: NHS hospitals in England.

Participants: 47,780 individuals (mean age 65 years, 55% male) in hospital with COVID-19 and discharged alive by 31 August 2020, matched to controls on demographic and clinical characteristics.

Outcome measures: Rates of hospital readmission, all-cause mortality, and diagnoses of respiratory, cardiovascular, metabolic, kidney and liver diseases until 30 September 2020.

Results: Mean follow-up time was 140 days for COVID-19 cases and 153 days for controls. 766 (95% confidence interval: 753 to 779) readmissions and 320 (312 to 328) deaths per 1,000 person- years were observed in COVID-19 cases, 3.5 (3.4 to 3.6) and 7.7 (7.2 to 8.3) times greater, respectively, than in controls. Rates of respiratory, diabetes and cardiovascular events were also significantly elevated in COVID-19 cases, at 770 (758 to 783), 127 (122 to 132) and 126 (121 to 131) events per 1,000 person-years, respectively. RRs were greater for individuals aged <70 than ≥70 years, and in ethnic minority groups than the White population, with the biggest differences observed for respiratory disease: 10.5 [9.7 to 11.4] for <70 years versus 4.6 [4.3 to 4.8] for ≥70 years, and 11.4 (9.8 to 13.3) for Non-White versus 5.2 (5.0 to 5.5) for White.

Conclusions: Individuals discharged from hospital following COVID-19 face elevated rates of multi- organ dysfunction compared with background levels, and the increase in risk is neither confined to the elderly nor uniform across ethnicities. The diagnosis, treatment and prevention of PCS require integrated rather than organ- or disease-specific approaches. Urgent research is required to establish risk factors for PCS.

Regarding the above 313614 people have been admitted to hospital in the UK already. It seems like there may be circa 100 000 people with chronic long term conditions that have required another stay in hospital. I expect that there will be many more who are affected but didn’t need to go to hospital.
