Hospital bosses have escaped action from the Health and Safety Executive after improving patient safety at a dialysis unit.
Managers at Leicester's hospitals have made the changes after two patients who had dialysis next to each other at the Harborough Lodge renal unit, in Northampton, had died from tuberculosis (TB) – one in 2011 and one in 2012.
It also emerged 13 staff working at the unit run by Leicester's hospitals had tested positive for the infection.
One was hospitalised after developing active TB but 12 others were found to have only the latent form of the disease.
The unit originally had six beds but was expanded to include 15 dialysis stations and catered for 84 patients a week.
However, the numbers have now been cut back to 60 a week.
Lisa Cowan, the manager for renal and transplant services at Leicester's hospitals, said: "We have taken out four 'stations' which means the space between patients is bigger.
"About 24 patients have been relocated to other units. By and large we have transfered them to units within 30 minutes of where they live."
Ms Cowan said the 11 units for which Leicester's hospitals are responsible for had also been checked. This includes satellite units in Lincolnshire, Northamptonshire and Cambridgeshire, as well as Leicestershire.
Ms Cowan said there had been no further cases of TB.
It is understood the Health and Safety Executive issued an improvement notice because a risk assessment had not been undertaken as to whether patients might be at risk of diseases such as TB due to their close proximity while having dialysis.
However, at a meeting, Leicester hospitals' chief executive John Adler said the action plan in response to the notice had been submitted and the Health and Safety Executive would not be taking further action.
Dr Philip Monk, a consultant in health protection at Public Health England, said: "Some patients with TB are highly infectious, while others do not appear to infect any of their close contacts.
"Having thoroughly investigated the incident in accordance with national guidelines we are satisfied that all necessary public health actions have been put in place."
