Re: Almost third of UK Covid hospital patients readmitted within four months
#2The article doesn't give us quite enough information - what percentage of hospitalised Covid patients are over 70? 70 year olds are getting to the point where they spend a lot of time in hospital.
The "hospitalised for Covid" part of the sample group is introducing a lot of bias. Fit, young and healthy people are much less likely to end up in hospital. So it makes sense from the first that the group is suffering more problems than a general population control group.

From the study:
> At baseline, individuals with covid-19 had a mean age of 64.5 (standard deviation 19.2) and 54.9% were men. Compared with the general population, individuals in hospital with covid-19 were more likely to be: male, aged 50 or more, living in a deprived area, a former smoker, and overweight or obese (table 1). Individuals with covid-19 were also more likely to be comorbid than the general population, with a higher prevalence of previous admission to hospital and of all measured pre-existing conditions (most notably hypertension, major adverse cardiovascular event, respiratory disease, and diabetes).
> Individuals discharged from hospital after acute covid-19 had increased rates of multiorgan dysfunction (particularly respiratory and cardiometabolic) compared with a matched control group from the general population
> The rate ratio of multiorgan dysfunction (comparing individuals with covid-19 and matched controls) after discharge was greater in those aged less than 70 than in those aged 70 or more, and in ethnic minority groups than in the white population
> Our findings suggest that the diagnosis, treatment, and prevention of post-covid syndrome requires integrated rather than organ or disease specific approaches

Four times more often than the control group.
Over a mean follow-up of 140 days, nearly a third of individuals who were discharged from hospital after acute covid-19 were readmitted (14 060 of 47 780) and more than 1 in 10 (5875) died after discharge, with these events occurring at rates four and eight times greater, respectively, than in the matched control group. Rates of respiratory disease (P
Re: Almost third of UK Covid hospital patients readmitted within four months
#5what I find to be even more astonishing: "and about one in eight had died", so 1/8 of those who were in hospital for covid AND discharged afterwards, died within 4 months. We also had another article in the guardian that said that 1 million of people in the UK suffer from long covid ("Symptoms vary but include fatigue, muscle pain and difficulty concentrating."): https://www.theguardian.com/society/2021/apr/01/long-covid-s...

Worth mentioning that the control group wasn’t matched for hospital admission status, while the study group was solely people who ended up in the hospital. I’m guessing that the authors likely could have acquired the data to match a control group of people who had been admitted to the hospital, so I’d be curious to see what the results would’ve been there.
According to the paper, this control group was picked because, essentially, that’s what the authors wanted to choose:
> We selected controls from the general population rather than matching to non-covid hospital admissions to determine the increased risk after hospital admission for covid-19 versus no hospital admission for covid-19 (that is, compared with the expected risk for people with similar personal and clinical characteristics in the general population).

The ICNARC reports give more information. It's only for ICU.

Page 29 has a chart for spread of age. Most people (88%) live without any assistance in day to day activity.

#8There is a ton of selection bias here, these are already generally speaking very unhealthy people.

That's why the study looked at a control group, to try to account for that bias (as the abstract says, the control group was chosen to match "personal and clinical characteristics").
It's always possible they missed a factor, that's always a risk in such research, but they worked hard to address that possibility.
