Re: I would imagine
I fear that may not be quite right.
It is well known that staffing levels decrease at night and weekends. It would appear from this study that what many in the NHS have felt, actually is true: reduced staffing levels lead to increased morbidity and mortality,
I believe the medical royal colleges have tried to impress this upon the "powers that be" for years: we need more staffing round the clock, 24/7. Hospitals should never run on "skeleton staff", regardless of the time of days or day of the year.
But, of course, this comes at a price. And when hospitals are struggling to keep the staff they already have or are considering redundancies, increasing staffing levels is clearly not happening any time soon.
I think it's important, however, to get a grip on reality: Healthcare in the NHS is of very high quality even if individual patients experiences may not always be so. It's good that these "deficiencies" are brought to light, though. The NHS strives to always improve. My opinion anyway.
