Chief coroner Dr. Charles Trainor said the inquest came at the recommendation of Cyril Moyse, the coroner in Prince County who investigated Rogerson's death.
"After some further investigation we talked to the Attorney General's department and we are proceeding to have an inquest," said Trainor, who could provide only a few details of what led to the decision to hold an inquest.
"The reason for the inquest is to answer the questions, who, where, when and by what means did (Rogerson) die."
Rogerson died on Oct. 14, 2010, at the provincially operated Wedgewood Manor.
According to her death notice, Rogerson was 83 when she died.
Health P.E.I.'s Cecil Villard, executive director of home and long-term care, says his group, which oversees health care on the Island, will participate fully in this process.
"Our staff and physicians are committed to providing safe, high-quality health care. We anticipate that this inquest will support us in this commitment," Villard said in a statement issued late today.
"As this matter is now the subject of a legal proceeding, no further information can be shared."
Wedgewood Manor directed a request for comment to Health P.E.I.
The inquest will be held on March 26 and 27 at the Prince County Court House in Summerside.
