26/42 Are there any national datasets that accurately capture what is going on? The brilliant @jburnmurdoch has highlighted number of admissions into ICU. The message from his animated chart (click on link) couldn’t be clearer – this winter is v unusual: https://t.co/76ZvHU2pmV.


27/42 Some sceptics arguing covid-19 tests are inaccurate. PCR tests not 100% accurate but hospital inpatient testing accuracy much increased by frequency of testing (typically admission, days 3 & 6/7, then weekly). This means very low numbers of overall false positives.

28/42 Some sceptics argue that the published covid-19 positive inpatient numbers include both those admitted with covid-19 and those who acquired covid-19 in hospital. And that there are significant numbers of patients who have acquired covid-19 in hospital.

29/42 Covid-19 positive test data has always included anyone testing positive, irrespective of initial diagnosis. And the NHS has always acknowledged that hospital acquired (nosocomial) infection is a big issue. Hospitals are working incredibly hard to control it….

30/42 …The NHS regularly and completely transparently publishes nosocomial infection data, by hospital. But neither issue affects the degree of pressure that hospitals are under. Every inpatient, irrespective of initial diagnosis/infection source, occupies a hospital bed.

NHS beds, an explainer


Under normal circumstances, most NHS acute hospitals will have several types of inpatient areas

1. Assessment unit
2. Specialty wards
3. Intensive care

As well as outpatients, emergency department, day case surgery etc.

Patients admitted from A&E would go to 1, then move to 2. Some might go directly to 2, sickest ones to 3.

In many hospitals, the assessment unit is vital to flow of patients out of Emergency Department.

With COVID, several blocks have been introduced. Firstly patients have to be treated as "hot" in 2m apart bed spaces until their test results are back. This reduces an average six bedded bay to four.

There are rapid tests that turn around in around an hour or two, but their availability is limited. PCR still takes up to 24 hours to get back (often quicker), and lateral flow in the population admitted to hospital isn't sensitive enough to pick up silent cases.
