The Newfoundland and Labrador government and its largest health authority are expected to reveal Wednesday how much they have achieved in the wake of a hard-hitting inquiry into cancer testing errors.

Justice Margaret Cameron's final report into hormone receptor testing — which documented breakdowns at virtually every level of the health-care system — asked for a one-year update on what has been done with her findings.

Eastern Health and Health Minister Jerome Kennedy are expected to hold a news conference Wednesday to identify what has happened on Cameron's 60 recommendations.

Most centered on improving quality in the labs, documenting and reporting mistakes and providing more training and education for technologists.

Cameron, who sits on Newfoundland Supreme Court's appeal division, was appointed to the inquiry amid revelations that Eastern Health had not fully revealed the extent of errors with hormone receptor test results, which are key in determining whether a patient can benefit from the drug Tamoxifen.

Cameron's report exposed numerous problems at Eastern Health, from poorly trained and supervised staff to missed warnings at the management and political levels.

In an interview in December, Eastern Health chief executive officer Vickie Kaminski said work was underway on all recommendations, and that between 15 per cent and 20 per cent of them were fully implemented.

However, Kaminski, who was hired just last year, said it would take some time before all of the recommendations are in place.

"If you looked at the complexity of the report that Justice Cameron gave us, it was very comprehensive," she said.

"So, we're looking at a multi-year plan that's going to need to be put into place to accomplish everything."
