In a work environment where higher ups are doing system planning, they don't really get the point unless it is quantified. If they can't count it, then it doesn't count.
The study is from England, where the healthcare system is struggling at the moment. Patients spend the whole day on a trolley or on a chair or in an ambulance because there are no beds and you can't close a hospital when it gets overloaded. Planners think they can get the same nurses to handle the workload. Planners won't see that this is causing deaths till someone counts like this and shows them. Even then there's no funding, there are no nurses on the market to employ and there's no good solution.
Although this finding looks obvious, the point needs to keep being made to try to push for change.
