Hailed globally as a pioneer of the hospice moment, Sister Frances Dominica, 72, a Anglican nun, has been told not to return to two Oxford hospices she set up.
According to The Daily Telegraph she was given the orders after a police investigation into historic allegations, that she denies.
Sister Frances founded Helen and Douglas House in Oxford and has a number of honours, including Woman of the Year, she is patron to a number of charities and Deputy Lieutenant of Oxfordshire.
She was arrested in 2013 following allegations made against her by two women.
However the Crown Prosecution Service did not take further action due to insufficient evidence to ensure a realistic prospect of conviction.
Sister Frances has always denied the allegations against her.
She did stand aside as a trustee to the hospices as a risk assessment was carried out.
The report remains confidential, however the document carried out on behalf of her order, the Society of All Saints Sisters to the Poor, has recommended that she "will not return" to her former role.
Society of All Saints Sisters to the Poor says it is "carefully considering" its response.
Sister Frances originally trained as a nurse and became Mother Superior after she joined the order.
No details of the allegations or action to be taken have been released.
In a joint statement the hospice trustees said: "We can confirm Sister Frances Dominica will not to return to Helen and Douglas House.
"The Trustees of Helen and Douglas House decided to implement the recommendations of an independent risk assessment report, after careful discussion and analysis..
"We wish to reiterate that no allegations contained within the report relate in any way to activities at Helen and Douglas House and that, as soon as the allegations were raised in July 2013, Sister Frances agreed at our request to step away from all activity at Helen and Douglas House."
