Great Britain is being rocked by a health care scandal at one of its government-run hospitals.

A two-year-long inquiry has exposed widespread neglect and malpractice that led to the unnecessary deaths of up to 1,200 patients at Stafford Hospital in England between 2005 and 2008.

The London Telegraph reported doctors, nurses, and hospital staff were understaffed and overwhelmed. Consequently, critically-ill patients were regularly overlooked and even given the wrong medication.

The latest evidence showed the staff were threatened with firing if they could not keep up with the quotas and regulations of Britain's National Health Service.

The investigation showed hospital managers were reportedly more concerned with cutting costs than caring for patients.
