I was one of those "back room staff". I still worked 12+ hours a day, 7 days a week to try and keep the NHS functioning. Back room staff are how front line staff have any (if not the optimal) PPE, how patients have access to the right medicines, how the computer systems still worked, how people still got paid and how you know how many patients you have in the hospitals, with what diseases, what symptoms and what treatments and therefore what else you need to provide.
Early in the pandemic, we had limited data and limited forecasts.
I spent my time trying to work out which areas of the hospital would become overwhelmed so we could divert resources to them in advance and prevent that happening. For example, COVID patients need lots and lots of oxygen. You want to put them in one place, so they don't infect anyone else, but if you do you can't physically transfer enough oxygen to each one. So instead they need to be spread out. How do you do that but minimise the hospital space taken up by then so you can have as many non-Covid patients as possible and still keep them safe? Rinse and repeat for ICU requirements, dialysis machines. For how you manage PPE when there isn't enough. How many nurses, that you need elsewhere, do you take off shift to train up on ICU machinery? How many extra ICU beds should you try to cobble together, bearing in mind ICU beds take away resources from non-ICU areas? How many COVID wards do you need to have planned for? How do you keep patients safe if they don't have COVID while they do have a respiratory illness while you wait for their tests to come back?
None of that was frontline work. But I built from scratch a model that enabled us, not hugely well, but as well as I could, to plan those things.
We had very limited knowledge of how well the general public would obey the lockdown rules. They were vastly more compliant than we were expecting. That compliance stopped hospitals being totally overrun.
I'm forever grateful to people for their sacrifices. It saved many lives because without it there would have been many more deaths, from people who needed CPAP but couldn't get it, or renal fluids but for whom there was no dialysis machine. I think the isolation experienced before e.g. bubbles were introduced was awful and I hope we've learnt lessons from that. But at the time the fear was bodies piling up so fast that the morgues would be full, so I understand why that didn't get prioritised the way it perhaps should have.
