When you go to hospital you expect to be safe. But File on 4 has discovered that many patients and staff who are victims of sex attacks say not enough is done to deal with the perpetrators - and hospital managers ignore complaints. The programme examines startling data on the number of reported cases and asks what's being done to prevent sexual assaults in hospitals.
