Northern territories have highest rate of alcohol, drug-related hospitalization: study

Canada's three northern territories have the highest rate of hospital stays because of harm caused by alcohol and drugs, according to a new report fromthe Canadian Institute for Health Information (CIHI).

In its 2017 to 2018 data released Thursday, CIHI numbers show more than 400 Canadians are hospitalized every day as a direct result of using these substances which includes alcohol, opioids, cannabis, cocaine, and hallucinogens, among other mixed or unknown substances.

In the North, the rate of hospitalization for substance use is even higher more than four times the national average.

At the hospital, harmby substance usecan take the form ofinjuries or liver cirrhosis due to alcohol, seizures due to substance withdrawal, ora person developing psychosis after using cannabis.

The study has found more than 155,000 hospital stays were due to substance use across the country in 2017 to 2018.

"To put that in context, that's a lot more than heart attacks and strokes combined," saysMlanie Jose Davidson, director of CIHI's health system performance, and one of the authors of this study.

The average Canadian rate is 477 cases per a population of 100,000.

In Nunavut, that number is870. In the Yukon, it's more than double the national average rate at 1,022.

But the Northwest Territories had the highest rate of hospital stays due to substance use in the country with a rate of 2,015 cases per 100,000 people, more than four times the national rate.

Most northern communities have a notably smaller population pool for instance, about 20,000 in Yellowknife which isfar from the 100,000 standard used to calculate the rate.The study also does not include numbers for children younger than 10 years old, nor hospital stays for reasons partially due to substance use.

'Territorial trend' of alcohol hospitalizations

About half of hospitalizations nationally are due to alcohol.

Davidson says in Yukon, that number is closer to 80 percent.

"It's also very high in the Northwest Territories. So it does seem to be a territorial trend," says Davidson.

Nationally, the study shows there are two peaks inage groups that end up more in the hospital people between 25 and 34, and people between 50 and 64 years old.

On average, two out of three hospital stays are by men. But that's not the case for teenagers from 10 to 19 years old, says Davidson.

In that age group, there were more girls than boys hospitalized across Canada for substance use, she says. Cannabis is one of the main drivers for that group.

"Teenage girls haven't fully grown yet and their metabolisms are quite adjusted, so they might think that they can consume more than they actually can physiologically," explained Davidson.

One in 10 hospitalizations in Canada are related to harm caused by opioid use, the study states.

Davidson says she hopes the study can help educate the public, and also be used by governments and health plannersto understand the scope of services needed across the country.

"Alcohol and cannabis are a lot more acceptable and socialized in our culture and we sometimes forget that those can also have harms ... both in the short term and in the long term," says Davidson.
