In a statement, the United Lincolnshire Hospitals Trust, which runs the Pilgrim Hospital in Boston, says it has carried out a review on nurse staffing levels.
"We are committed to providing high quality care for our patients and over the last year we have successfully recruited to a large number of clinical posts for both nursing and medical staff.
"We have also carried out a review of the nursing establishment on all wards across all hospital sites in the Trust and are in the process of introducing a new staffing template to be used on every ward.
"We understand the data used is more than a year old and many changes, such as those described have taken place since then."
