A 2,324-patient study found 6.2% complication rates at accredited international facilities, comparable to domestic US rates. The data shows where the real risks are.
Is medical tourism safe? A 2024 study published in PMC (opens in new tab) tracked 2,324 international patients undergoing 7,141 procedures at accredited facilities in Colombia and found an overall complication rate of 6.2% per patient and 2.2% per procedure. Of those complications, 93% were local (wound disruption, infection, hematoma) and manageable. All patients achieved full recovery without long-term complications.
That 6.2% rate matches published benchmarks from leading US practices for comparable procedures. The question was never whether surgery abroad is safe. The question is which hospitals and which vetting process you use to get there.
Data current as of April 2026.
The safety conversation around medical tourism suffers from two problems: people who've never looked at the data assume the worst, and people selling medical tourism packages claim zero risk. Neither is true. Here's what the published evidence says.
The 2,324-patient Colombian study is the largest published dataset on medical tourism complication rates. Key findings from the PMC-published analysis (opens in new tab):
Metric | Rate |
|---|---|
Overall complication rate (per patient) | 6.2% |
Complication rate (per procedure) | 2.2% |
Local complications | 93% of all complications |
Systemic complications | 7% of all complications |
Deep wound disruption | 2.9% |
Surgical site infection | 1.5% |
Hematoma | 1.3% |
Deep vein thrombosis | 0.2% |
Pulmonary embolism | 0.1% |
Long-term morbidity | 0% |
All cases were managed in the hospital. The study covered 1,363 patients with 4,244 procedures tracked from 2020 to 2024. Eighty-nine percent of patients traveled from the US or Canada.
Context matters. The Johns Hopkins University study published in the BMJ (opens in new tab) estimated that more than 250,000 deaths per year in the US result from medical errors, making medical error the third leading cause of death after heart disease and cancer. That's in the US, at US hospitals, with US-trained physicians.
The CDC's Behavioral Risk Factor Surveillance System (opens in new tab) surveyed medical tourists and found that 5% reported unexpected or undesirable outcomes from care received abroad. The remaining 95% reported no adverse outcomes. Of those who experienced complications, 67% sought follow-up care in the US upon returning home.
JCI-accredited international facilities show infection rates of 2.1 per 1,000 patient-days (opens in new tab) in published data from accredited Colombian hospitals - comparable to or below US hospital benchmarks.
The CDC and published literature identify consistent risk factors for medical tourism complications. These aren't random - they follow predictable patterns.
Unaccredited facilities. The CDC's medical tourism guidance (opens in new tab) identifies facility quality as the primary differentiator. Surgical site infection rates at developing-country ICUs run at least 3-fold higher (opens in new tab) than US rates - but that statistic covers all facilities, accredited and unaccredited. The complication rates at accredited centers tell a different story.
Antibiotic-resistant infections. Over-the-counter antibiotic availability in some countries creates resistant bacterial strains. The CDC recommends that patients hospitalized after returning from high-risk destinations be placed on contact isolation and screity screened for resistant organisms.
No continuity of care. A German study (opens in new tab) found that 26% of medical tourists face continuity issues with post-procedure follow-up. When your surgeon is 7,000 miles away, managing a slow-healing wound or an unexpected complication requires planning.
Unqualified surgeons. This is almost exclusively a problem at unaccredited clinics. At Class 3A hospitals in China or JCI-accredited hospitals elsewhere, surgeons hold credentials verified by national medical boards.
Over 1,000 healthcare organizations in more than 70 countries (opens in new tab) hold JCI (Joint Commission International) accreditation, the international extension of the same body that accredits US hospitals.
But accreditation alone isn't the whole story. China's domestic rating system - the Class 3A designation - applies more granular standards than JCI and covers 1,795 hospitals nationwide (opens in new tab). A Class 3A hospital has scored 900+ out of 1,000 on government quality metrics, maintains 500+ beds, and provides tertiary care. For international patients, this system is actually more transparent than the US, where no single mandatory quality rating exists (opens in new tab) - hospitals can be rated by CMS Stars, US News, Leapfrog, or none of the above.
See our guide to China's hospital rating system for a detailed breakdown.
Estimates vary by methodology:
The CDC Behavioral Risk Factor Surveillance System (opens in new tab) found that 1.32% of surveyed US residents had traveled internationally for pre-planned medical care, translating to approximately 1.13 million individuals
A Deloitte consumer survey (opens in new tab) estimated 875,000 Americans
The US International Trade Commission (opens in new tab) estimated 150,000-320,000 inpatient medical tourists from the US
The primary reasons cited by medical tourists, per the CDC data: 51% said it was too expensive in the US, 14% said it wasn't covered by insurance, and 6% believed outcomes would be better abroad.
The global medical tourism market reached $66.8 billion in 2024 (opens in new tab) and is growing at 12-25% annually depending on the research methodology.
Knowing that accredited facilities are safe doesn't tell you which specific hospital to choose. Here's a framework:
Check surgical volume. High-volume centers produce better outcomes across virtually every procedure. A hospital performing 3,000+ joint replacements per year (like PLA 301 Hospital in Beijing) has a fundamentally different experience base than one performing 200. Ask the international department for annual procedure-specific volumes.
Verify surgeon credentials. Request the surgeon's CV. Check whether they've published in peer-reviewed journals (search their name on PubMed (opens in new tab)). Published research isn't mandatory, but it signals engagement with international standards.
Ask about complication management. What happens if something goes wrong? Does the hospital have an ICU? What is the surgeon-to-patient ratio during recovery? Does the hospital offer complication coverage? These questions matter more than any accreditation logo.
Get a second opinion before you fly. Send your records and imaging to the international department for remote evaluation. A credible hospital will tell you if you're not a good candidate for surgery abroad - and that willingness to turn away patients is itself a trust signal.

The biggest risk in medical tourism isn't the surgery - it's choosing the wrong facility. Every documented horror story involves unaccredited clinics, too-good-to-be-true pricing, or surgeons without verifiable credentials. At accredited facilities with published outcome data, complication rates track with domestic benchmarks.
Meanwhile, the risk of not getting surgery has its own data. KFF reports (opens in new tab) that about one-third of American adults skipped or postponed needed healthcare due to cost in the past 12 months. Delayed joint replacement means worsening mobility. Delayed cardiac procedures mean higher risk of acute events. Delayed cancer treatment means later-stage diagnosis.
The safety question isn't just "is surgery abroad safe?" It's "is postponing surgery because you can't afford it at home safer?" For many patients, the answer is no.

The largest published study found a 6.2% complication rate per patient (2.2% per procedure) at accredited international facilities, based on 2,324 patients tracked over four years (opens in new tab). Of those, 93% were local complications managed in-hospital, and no patients experienced long-term morbidity. The CDC estimates a 5% rate (opens in new tab) of unexpected outcomes among all medical tourists, including those treated at unaccredited facilities.
Surgery at Class 3A hospitals in China follows the same evidence-based protocols used at top US centers, with the same equipment and comparable training standards. China performs 900,000+ hip replacements (opens in new tab) and 228,000+ cardiac surgeries annually (opens in new tab) at documented facilities. Fuwai Hospital in Beijing, the world's largest cardiovascular center, has maintained CABG mortality rates below 0.5% for 10 consecutive years (opens in new tab).

Over 1,000 healthcare organizations in more than 70 countries (opens in new tab) hold JCI accreditation. China has approximately 46 JCI-accredited hospitals, but the more meaningful metric is China's domestic Class 3A designation, which covers 1,795 hospitals with rigorous government quality standards.
About 67% of medical tourists who experience complications seek follow-up care at home, per CDC data (opens in new tab). Bring your complete surgical records, discharge summary, and imaging back to the US. Most US physicians can manage follow-up care based on standard protocols regardless of where the original surgery occurred. Major international hospitals also offer telemedicine follow-up for post-discharge monitoring. Consider purchasing complication coverage insurance ($50-$200) before travel.
Yes. The Johns Hopkins study published in the BMJ (opens in new tab) estimated more than 250,000 deaths annually from medical errors in US hospitals, making it the third leading cause of death. The CDC's death certificate system doesn't separately classify medical errors, so this number doesn't appear in official mortality statistics. This doesn't mean US hospitals are unsafe - it means medical risk exists everywhere, and the relevant comparison is between specific hospitals, not between countries.
DVT risk approximately doubles after long-haul flights (over 4 hours), according to research published in JAMA Internal Medicine (opens in new tab). The absolute risk is roughly 1 in 6,000 for healthy passengers per long-haul flight. Post-surgery, the risk increases - DVT occurs in up to 1 in 3 patients after major surgery without prophylaxis. With proper blood thinners, compression stockings, and in-flight movement, the risk drops significantly. Your surgeon will prescribe a specific DVT prevention protocol based on your procedure and recovery timeline. See our flying after surgery guide for detailed timelines.
Medical tourism safety comes down to hospital selection, not geography. Accredited facilities with published outcome data produce complication rates that match or beat domestic benchmarks. Unaccredited clinics with suspiciously low prices are where the horror stories come from.
