Trends and Determinants of Tramadol Consumption in Chile: Evidence From National Health Surveys (2003–2017)
This study analyzes Chilean National Health Surveys from 2003 to 2017 and reveals a dramatic 19-fold increase in tramadol consumption, which disproportionately affects older adults, women, and individuals with osteoarthritis or depression, highlighting the urgent need for targeted opioid stewardship and integrated pain management strategies.

The Big Picture: A Quiet Surge
Imagine the Chilean population as a giant, diverse garden. For a long time, a specific type of "weed" called Tramadol (a painkiller often thought of as a "gentler" opioid) was barely visible in this garden.
Between 2003 and 2017, the researchers took three snapshots of this garden using a massive, national survey called the ENS (National Health Survey). They found that while Tramadol was once a rare sight, it has quietly but significantly multiplied over the last two decades.
The Numbers: From a Drop to a Stream
Think of the usage rates like water levels in a bucket:
- 2003: The bucket had a tiny, almost invisible drop of water (0.08% of people).
- 2010: The water level rose to a small puddle (0.60%).
- 2017: The bucket was now a full stream (1.77%).
When the researchers adjusted for age, gender, and education, they found that by 2017, the odds of someone using Tramadol were 19 times higher than they were in 2003. It wasn't just a little bump; it was a massive shift.
Who is Using It? (The "Who's Who" of the Garden)
The growth wasn't spread evenly across the whole garden. It clustered in specific areas:
- The Older Generations: The "weed" grew mostly among adults aged 45 and older. By 2017, nearly 4% of people aged 45–64 and over 3% of those 65+ were using it. The youngest group (17–24) barely had any at all.
- Women: Women were more likely to be using Tramadol than men, almost like a double dose of the effect.
- The Education Gap: This is a crucial finding. In the beginning, usage was low everywhere. But by 2017, people with lower levels of education were using it at a much higher rate (over 4%) compared to those with higher education (less than 1%). It's as if the "weed" grew tallest in the parts of the garden that were already struggling.
Why Are They Using It? (The Roots)
The researchers dug into the soil to see what was feeding this growth. They found two main "roots" that were strongly connected to Tramadol use:
- Osteoarthritis: This is the wear-and-tear of joints (hips and knees). Because Tramadol was officially added to the list of essential medicines for treating this condition in 2009, it became much easier to get. The study found that people with osteoarthritis were 10 times more likely to be using Tramadol than those without it.
- Depression: People reporting depression were also 10 times more likely to be using Tramadol. The paper suggests that when pain and mental health struggles happen together, it often leads to higher medication use.
Interestingly, the study found that Tramadol use didn't just spike in one specific group. Instead, it grew in parallel across almost all groups (like a tide rising everywhere at once), except for the osteoarthritis group, where the sheer number of people with the condition explained the big jump.
The "Safety" Myth vs. Reality
The paper notes that Tramadol is often seen as the "safer" cousin of stronger opioids. However, just because it's "safer" doesn't mean it's harmless. In Chile, there are already warning signs:
- It's a leading cause of opioid poisonings.
- It's sometimes sold illegally.
- People often don't realize the risks involved.
Currently, getting Tramadol in Chile is like getting a ticket to a concert that requires a "retained prescription" (you keep the prescription, but the rules aren't as strict as for harder drugs). This makes it easier to access, but perhaps not as closely monitored as it should be.
The Takeaway
The study concludes that Chile is facing a new reality. Tramadol use has exploded, particularly among older women, people with lower education, and those suffering from joint pain or depression.
The authors suggest that to fix this, the country needs a "stewardship" plan. Think of this as a new set of gardeners who need to:
- Watch the garden more closely (better monitoring).
- Teach doctors how to prescribe it more carefully (safer prescribing).
- Offer help for both the physical pain and the mental health struggles together, rather than just handing out pills.
In short, what started as a small, manageable drop of water has turned into a significant stream that needs careful management to prevent it from flooding the garden.
