A longish thread on RESTARTING ELECTIVE SURGERY for a Saturday morning

First up it is very clear we need to do it

Some patients have life threatening or painful conditions that need addressing.

Provision of healthcare is a must for any civilised society

1/n
The volume of missed surgery is huge

We've probably lost at least 2 million cases in 2020 and we now have a waiting list of about 5 million

Different sources have broadly similar numbers between 2 and 3 million additional cases on the waiting list

2/n
The @RCoANews ACCC Track survey has examined the impact of the pandemic on surgical services
In early December pre the big surge)
nationalauditprojects.org.uk/ACCC-track-Ana…

Many hospitals are unable to undertake elective surgery (red) or struggling (orange)

Space/staff issues most prominent

3/n
What this translates to is more than 2 in every 3 hospitals were not in a state to do planned surgery

...and this was in early December before the big surge in January
nationalauditprojects.org.uk/ACCC-track-Ana…

4/n
The @RCoANews ACCC Track survey showed the impact on surgery
nationalauditprojects.org.uk/ACCC-track-Ana…

In early December (before the big surge)

Surgery is reduced
-elective non cancer surgery 36%
-children's surgery 35%
-cancer surgery 25%
-emergencies 10%

5/n
@RCoANews ACCC Track survey showed the overall impact on surgery
nationalauditprojects.org.uk/ACCC-track-Ana…

Cases lost
-a fall of 28% across the board
-5500 each day
-1,000,000 a year

But this is a huge underestimate because
-all surgery stopped in surge 1
-most surgery stopped in Jan-Feb

6/n
So best estimate is we have backlog of >2 million cases

To clear this needs working at
-200% maximum capacity for 1 yr
-140% maximum capacity for 3 yrs
-110% maximum capacity for 10 yrs

Remembering that maximum is maximum!

(& BMA seems to have used the same ideas as me)

7/n
So whichever way we look at it we have a problem in addressing the unmet healthcare needs of 2020

We cannot solve this in a short period

It will require planning, patience and endurance

8/n
BUT there are further problems
The pandemic has not finished!

The importance of global vaccination cannot be over emphasised

Without it we risk emergence of variants that evade the vaccine and put us back to square one

9/n
This is exactly what happened in Manaus (Brazil)

After widespread infection in wave 1 natural (herd) immunity was at 76%
A new variant emerged and evaded immunity leading to a massive second surge

10/n
The solutions are global vaccination
To reduce overall transmission and reduce evolutionary pressure on (opportunity for) the virus which leads to new variants

Global efforts are supported by @ACTAccelerator @CEPIvaccines & @gavi

…-publications.onlinelibrary.wiley.com/doi/full/10.11…

11/n
...& closer to home
The pandemic has not finished!

The rise in hospital work has been enormous & the volume of ICU work extraordinary

-140 temporary ICUs
-staff caring for 2x, 3x 4x normal numbers
-thousands of patients transferred between ICUs

12/n
The current fall in hospital and ICU admissions is almost entirely due to lockdown

It takes more time for vaccination to impact on ICU admissions - and even after that patients often stay a month on ICU. We're still busy!

…-publications.onlinelibrary.wiley.com/doi/full/10.11…

13/n
The impact on staff
-nurses
-doctors
-all other staff
has been enormous

Physical exhaustion
Untaken holidays

14/n
But many staff are not just tired
-most are depleted
-many are traumatised

All need rest
Some need help
More than 1 in 3 plan to reduce hours
Almost 1 in 5 may stop working altogether

15/n
Numerous organisations are calling out the need for
-a pause
-some rest
-a plan
@RCoANews @FICMNews @AAGBI
@ICS_updates
@TheBMA

Only by doing this will recovery of surgical services be safe, stable and sustainable

16/n
The main recommendations from @AAGBI @FICMNews & @RCoANews are here

icmanaesthesiacovid-19.org/towards-safe-s…

17/n
Restoration of surgical services is essential
-it should not be rushed into
-it will be a marathon
-global vaccination, allowing staff holidays and psychological support are essential

Just as important innovation & new pathways that will emerge

Strong article @By_CJewett on AEROSOLS, COUGH, the complex discussion around risk for HEALTHCARE WORKERS and FFP3/N95 masks

With @drjulesbrown me and others

Here's a bit of the evidence behind it
1/19

theguardian.com/us-news/2021/m…
First the archetypal metanalysis by Tran which seemingly underpins the early approach by many public health organisations

Evidence base...
"We identified 5 case-control and 5 retrospective cohort studies which evaluated transmission of SARS to HCWs"
2/19

ncbi.nlm.nih.gov/pmc/articles/P…
As I often quote the excellent paper from @mugecevik shows important differences in viral dynamics between SARS and SARS-CoV-2

Infectivity from SARS-CoV-2 starts and finishes earlier
Hugely important for infection control strategies

A thread on why a slower lockdown release makes sense for the wide and younger community (& so for all)

ICU pressures will not fall for up to 8 weeks after similar falls in deaths
@john_actuary
1/n

…-publications.onlinelibrary.wiley.com/doi/full/10.11…
The reasons can be illustrated by the median ages of patients in the 3 groups affected by COVID
-patients who died (median age 83) @ONS
-hospital admissions (age 73) @ISARIC1
-ICU admissions (age 61) @ICNARC

Impact of vaccination is much slower in the younger groups

2/n
There's been evidence vaccination is impacting deaths in the older groups for some time

Nice to see this published
Working with @john_actuary from @COVID19actuary we’ve modelled impact of vaccination on
-deaths
-hospital admissions
-ICU admissions

…-publications.onlinelibrary.wiley.com/doi/full/10.11…
Vaccinating just by age would have this impact on the three measures

The lag in the last two is because the groups differ.

Median ages
-deaths 83
-hospitalised 73
-ICU 61

So the cohort who might get to ICU have to wait for vaccination
If the graphs are adjusted to account for
-gp2 health/social care workers
-gp4 extremely clin vulnerable
-gp6 high risk
They look like this with lag slightly reduced (and the health service staff protected)

Vaccinating 15% of popln
-huge impact on deaths
-modest impact on ICU

Round 3 of ACCC TRACK. Exploring impact of COVID on anaesthetic departments and surgical activity out now
@emirakur @jas_soar @HSRCNews @RCoANews

nationalauditprojects.org.uk/downloads/ACCC…
Only about a third of anaesthetic departments operating well in December- worse then October and before the new year surge hit Image
All but 14% of hospitals in a surge setting and half not able to meet ICU demand as normal Image

@nico111111 @rupert_pearse @JeremyFarrar An important piece by an excellent communicator laying out what it means when the NHS is 'overwhelmed'
@chrischirp

-first more difficult to provide care
-then standards of care reduce
-finally inability to provide even that care to some needing it

theguardian.com/commentisfree/…
Important to remember that pressure on NHS will last longer than high rates of mortality

As @chrischirp says if we reach the point where we cannot deliver care to some patients there need to be a plan

The @ICS has perhaps produced the best 'organisational overview'
