VIDEO: Surgical objects left in patients on the rise in Canada, data shows

553 foreign items — such as sponges and medical instruments — were left behind over a two-year period

More than 550 objects have been unintentionally left in Canadian medical and surgery patients between 2016 and 2018, and the problem appears to be getting worse.

A new report released Thursday by the Canadian Institute for Health Information says 553 foreign items — such as sponges and medical instruments — were left behind over that two-year period.

That’s a 14-per-cent increase between the most recent data collected 2017-2018 and statistics collected five years earlier.

It’s also more than two times the average rate of 12 reporting countries, including Sweden, the Netherlands and Norway, which had the next highest rates.

The information was examined as part of a broad look at how Canada’s health-care system compares to other member nations of the Organisation for Economic Co-operation and Development.

Tracy Johnson, CIHI’s director of emerging issues, said the data only notes how often the mistakes occurred, but not how or why.

“Often they are smaller things and they may be things like clips or sponges,” said Johnson, suggesting the reasons are likely complex and multifaceted.

“Some surgeries are long and complicated and if they have to change people during that surgery because some surgeries last a long time, it may be that things get missed because of that. It may be that they don’t have protocols in place — surgical checklists are one of the things that are utilized to try and prevent a number of things happening….

“What we know is patient safety is complicated. People don’t go to work to make mistakes but these things happen.”

Johnson said several peer countries, including the United States, the United Kingdom and Australia, do not report on cases where foreign objects are left behind, making comparisons difficult.

And the Canadian statistic is based on data provided by hospitals in only nine provinces.

Still, Johnson said there’s clearly work to be done to improve patient safety, noting the average rate of forgotten items was 9.8 incidents per 100,000 surgeries.

That number also varied widely between regions — from a low of 5.7 per 100,000 surgeries in British Columbia to about 15 per 100,000 surgeries in Quebec, said Johnson.

She suggested that variation may have more to do with how thorough one province’s counting and recording system might be versus another, rather than apparent deficiencies in care.

The information was examined as part of a broad look at how Canada’s health-care system compares to other countries.
