Where the evidence actually comes from
When an article quotes a "safety rate" for a destination, ask what kind of data it rests on. There are only a few sources, and each sees a different part of the picture:
- Home-country hospital reports. Surgeons and infectious-disease teams describe patients they treated after surgery abroad. They see the problems, not the trips that went fine.
- Public-health investigations. Agencies such as the CDC trace clusters of unusual infections back to particular facilities or regions.
- Surgeon surveys. Professional societies sometimes survey members about deaths or complications after a specific operation. That produces procedure-level estimates, not country-level ones.
- Clinic marketing. Self-reported numbers with no stated definitions, time frames or independent audit.
What is missing from all of these is a reliable denominator: how many people traveled for each operation, and how many recovered without trouble. Without it, no one can honestly calculate a risk rate for travelers.
What the largest US review found
The most thorough US summary is a 2022 systematic review from the University of Pennsylvania (McAuliffe et al., Aesthetic Plastic Surgery, 2022). The authors pooled 20 studies published between 2008 and 2021. Together they described 214 patients who had cosmetic surgery abroad and were then treated for complications in the United States.
| Finding | What the review reported |
|---|---|
| Most common procedures | Abdominoplasty 35.7%, liposuction 17.8%, breast augmentation 16.3%, foreign-body injections 6.2% |
| Most common complication | Infection, 50.9% of patients (superficial surgical-site infection and/or cellulitis) |
| Other complications | Pain 7.8%, wound dehiscence or healing problems 7.3%, granuloma 6.4%, seroma 4.6%, embolic events 3.2% |
| Severity | 36.8% needed hospital admission; 51.8% needed surgery |
| Duration | Average treatment lasted more than two months in every study; some patients were treated for up to a year |
| Where surgery took place | Dominican Republic 82.7%, Mexico 4.2%, Colombia 3.7% of the patients described |
Eleven of the studies reported nontuberculous mycobacterial infections. These often needed extensive surgical cleaning and long courses of antibiotics. Six studies reported side effects from that antibiotic treatment itself.
Why these numbers are not a risk rate
It is tempting to read the table as "half of patients get infections" or "the Dominican Republic is the most dangerous destination." The review supports neither. The authors are clear about the limits:
- Only complications were counted. Every patient in the review had a problem. The 50.9% describes what kind of problem those patients had, not how often travelers have problems.
- Most included studies were small. Many were retrospective reviews or single-patient case reports, and nine studies described just one patient each.
- Destination share shows who got written up. The country breakdown reflects which patients reached the US hospitals that published. It is not a ranking of countries.
- The real burden is probably larger. The authors think the problem is likely underestimated, because no reporting system tracks clinics whose patients have complications.
The review is still useful. It tells you which complications are serious enough, and common enough among those who return with problems, to plan around.
What public-health investigations add
The CDC Yellow Book (2026 edition) fills in context that case series can't. It says infections are the most common complication among medical tourists. It lists documented outbreaks, including nontuberculous mycobacterial surgical-site infections after cosmetic surgery in the Dominican Republic and carbapenem-resistant Enterobacterales (CRE) infections after invasive procedures in Mexico. It notes that antimicrobial-resistant organisms such as CRE and Candida auris appear more common in some destinations.
The CDC also lists noninfectious complications: blood clots, fat embolism, wounds reopening, contour problems and death. It explains that surgery and air travel each raise the risk of clots, and that traveling after surgery raises it further. The Yellow Book gives no numerical complication rates, which tells you something too: the federal agency that tracks this doesn't claim to know the overall rate.
Procedure-level data is more useful: the BBL example
Where good numbers exist, they tend to be about one operation and one technique, not about a country. Gluteal fat grafting is the clearest case. An ASPS task force set up in 2018 studied deaths after the procedure. It concluded that fat should be placed only in the subcutaneous space, above the muscle. In a 2023 ASPS article, one task-force surgeon cited recent survey data suggesting mortality is now roughly that of a tummy tuck, about one in 15,000 (ASPS, 2023).
That figure comes from surgeon surveys, not from travelers abroad, and it says nothing about any specific destination. What it does show is that the safety-critical variable here is a technical choice you can ask about directly. That is more useful than a national reputation. Our BBL travel conflict check covers the travel side of that operation.
What good data would look like
It helps to know what a trustworthy safety figure would need, so you can spot when one is missing. A meaningful complication rate for travelers would state:
- A clear population: which patients, which operation, at which facilities, over which years.
- A denominator: everyone who had the operation, not only those who later went to hospital.
- Definitions: what counted as a complication, from a minor wound problem to a return to surgery.
- Follow-up length: how long patients were tracked after surgery, including after they flew home.
- An independent source: collected or audited by someone other than the clinic being measured.
The sources above each meet some of these and not others. The US review has clear definitions but no denominator. CDC outbreak investigations confirm specific clusters but don't give overall rates. The BBL survey data covers a single procedure across many surgeons, not travelers specifically. Taken together, they show where to look. None of them answers "how safe is this country?"
How to use the data as a patient
Turn the pattern into questions
Infection is the complication most often reported, so ask how instruments are sterilized, who checks your wound and when, and what the clinic does if an infection shows up after you are home.
Ask for the surgeon's own figures, with denominators
"How many of this exact operation did you do last year, and how many of those patients went back to the operating room?" You can't audit the answer, but how specific it is tells you something. The vetting steps in our surgeon vetting guide help you check the claims you can verify.
Plan for long treatment, not just a quick fix
The review found treatment often lasted months. Know who at home would manage a complication and how you would pay for it before you book.
Tell clinicians at home where you had surgery
The CDC asks US facilities to take an explicit travel history. It recommends CRE screening for patients who had an overnight stay in a healthcare facility abroad in the past six months, and that screening is free through the Antibiotic Resistance Laboratory Network.
Discount any number without a source
A complication rate with no definition, time period or denominator is marketing, not data.
Red flags in "safety statistics"
A single country-wide complication percentage. Claims that a destination is "safer than the US" with no study cited. Rates that never say how long patients were followed. Numbers that only a clinic has seen. Our complications and recourse guide covers what to do if problems appear despite careful choices.
The Takeaway
The real data can't tell you which country is safe. It can tell you what tends to go wrong, how long it takes to fix, and which questions to ask. Point your research at the specific surgeon, facility and technique, and plan home follow-up before you leave.
Frequently asked questions
Is cosmetic surgery abroad more dangerous than at home?
No reliable comparison exists, because nobody counts how many people travel for each operation and how many recover without problems. The published evidence describes patients who had complications. It doesn't measure overall risk.
Which country has the safest cosmetic surgery?
The data can't rank countries. In the 2022 US review, the country breakdown reflected which patients were treated and written up at the reporting hospitals. Risk depends far more on the specific surgeon, facility and technique.
What complication is reported most often after surgery abroad?
Infection. It affected 50.9% of the patients described in the 2022 systematic review, and the CDC also names infection as the most common complication among medical tourists.
Why do some infections after surgery abroad take months to treat?
Some, such as nontuberculous mycobacterial infections, often need extensive surgical cleaning and long antibiotic courses. The review found average treatment lasted more than two months in every included study.
Should I tell my home hospital that I had surgery abroad?
Yes. The CDC asks US facilities to take an explicit travel history. It recommends CRE screening for patients who had an overnight stay in a healthcare facility abroad within the past six months.
