@andHelenknowsimmiserablenow Not necessarily. If a large scale incident or incidents occur of any kind, standards will be doubled, tripled, infinite for a period of time thereafter.
To draw a different comparison, and not use deaths as an example (feels poor taste) there was a big thing in a local trust where it emerged elderly people were not being fed at meal times adequately (for all manners of reasons) ..for a good few months, extra staff were employed, special meal time assistants employed, staff were watched by very senior members of staff at dinner time and handing out meals/feeding people became an absolute priority "stop everything, all hands on deck" special tabards were worn the lot , audits occuring. So figures in that particular area would have gone to put it so crudely, from "nobody's getting fed", to "everyone's getting fed and to a high standard".
You can see how you can apply that to cases of deaths.
Just to answer your question. Not drawing any conclusions on the case in question.
