A bit more on those 63 victims that Savile sexually abused between 1968 and 1992. Almost half of the victims - who were patients, staff, visitors, volunteers and charity fundraisers - were under 16, and 10 were under the age of 12, Dr Johnstone says.
Around one-third of his attacks were against patients, just over 90% of the victims were female. The sexual abuse ranged from inappropriate touching to rape.
Dr Johnstone says: "All NHS services should be alert to predatory sexual offenders like Savile who can be placed in a position of trust and authority."
Dr Johnstone says: "The individuals to whom these incidents were reported failed in their duty to protect. Consequentially, no intelligence about Savile's behaviour was gathered over the years and no action was taken. Whilst witnesses told us it was an open secret within the hospital that Savile was a lecher and general nuisance, none stated that they knew about his sexual abuse activities."
Dr Androulla Johnstone, who wrote the Stoke Mandeville report, says Savile was an "opportunistic predator who on occasion could also show a high degree of premeditation" when planning attacks.
Hattie Llewelyn-Davies, chair of Buckinghamshire Healthcare NHS Trust, says Stoke Mandeville Hospital is a "very different place today".

"It would appear that once again, in keeping with the other known instances of Savile's poor behaviour and sexual activities on the hospital site, the complaint was not escalated beyond the middle management level," it says.
On that formal complaint at Stoke Mandeville. The report says it was the "only formal, contemporaneous complaint" about Savile's sexual abuse brought to the attention of the investigation.
"It would appear that the hospital staff directly involved with this incident failed in their duty to protect the vulnerable children in their care. Restricting Savile's movements on a ward for the duration of a single patient's stay cannot be seen as an appropriate response. Had this case been managed in a robust manner Savile should have been suspended from the hospital at this stage and police notified," the report says.
"There was virtually unrestricted access to clinical areas at Stoke Mandeville Hospital during the 1970s and 1980s; this applied not only to staff access and freedom of movement, but also to patients," the report says.
Jimmy Savile was given a bedroom in a building used to accommodate young medical students at Stoke Mandeville Hospital.
