Medical tourism and local access to care is the central equity question in this field: whether treating foreign patients reduces what is available to the population of the destination country. It is asserted constantly in both directions, and the reviews that have examined it say in their own words that it has barely been measured.
The standard the question is asked against
Universal health coverage means that all people have access to the full range of quality health services they need, when and where they need them, without financial hardship. The service coverage index rose from 54 to 71 between 2000 and 2023, though for the period from 2015 progress dropped to one-third of the annualised rate compared with pre-2015 gains. About 4.6 billion people were not fully covered by essential health services in 2023, and in 2022 some 2.1 billion people faced financial hardship from out-of-pocket health costs, equating to 26 per cent of the population, down from 34 per cent in 2000.[1]
None of those figures is attributed by their publisher to medical tourism, and they are given here only to establish the scale of the access problem into which a destination’s private international-patient sector is inserted.
The displacement claim
The argument is that beds, theatre time, equipment and above all clinicians used for foreign patients paying privately are unavailable to local patients, and that the prices foreign patients can pay raise what local patients are charged.
A scoping review of effects records the possibility in its own framing, noting that medical tourism could ultimately lead to locals being priced out of their own health care system, and that it can contribute to an internal brain drain of trained medical workers. It also notes that investment in high-technology tertiary care benefits a limited number of patients for the high cost outlay. On departure countries it found no evidence of medical tourism affecting wait times or costs at the system level.[3]
The same review supplies the counterpoint, recording that most hospitals providing services to international patients are primarily dependent on locals.[3] If a hospital’s revenue comes mainly from the domestic market, a simple crowding-out story does not follow automatically.
What the reviews actually conclude
The OECD-commissioned review is the most direct. It states that there is no strong evidence that medical tourism creates a two-tier system, or that it exacerbates one, while recording that there is the possibility of resources being taken away from the domestic population, and that the primary concern is a system in which foreign patients use well-resourced private hospitals while locals have basic, under-resourced health facilities. On who gains, it concludes that the evidence base is scant to enable an assessment of who benefits and who loses out. It also records that there are no authoritative data on the number and flow of medical tourists between nations and continents, that estimates rely on industry sources which may be biased and inaccurate, and that the sources for the two-tier concern are mostly commentary and anecdote.[2]
The scoping review reaches the same place from a different direction, concluding that what is currently known about the effects of medical tourism is minimal and that speculation abounds, out of 203 included sources of which 6 were empirical studies reporting primary data. It warns that estimates in this field were heavily cited and recycled until they became treated as facts.[3]
A comparative study of three destination countries adds that the impact of medical tourism on health systems is as yet unknown due to a dearth of data, that there is an acute lack of reliable empirical data concerning medical tourist flows, and that access to such services by local consumers without the ability to pay is elusive, framing revenue gains as something that may come at the expense of local access.[4]
All three are from 2010 or 2011. No later systematic review of this question was located for this entry, so their verdict should be read as describing the literature of that period rather than the present state of it.
Where the equity question sits in practice
A study based on 150 in-depth interviews with health system stakeholders in Mexico, Guatemala and Barbados concluded that development of the sector is primarily being driven by public investment promotion agencies and the private health sector seeking economic benefits, with limited consideration and planning for the health equity concerns medical tourism raises.[5] That is a finding about how the sector is governed rather than a measured equity impact, and it is the most specific thing available.
A case that is often misattributed
One documented instance of private hospitals failing domestic access obligations is frequently cited in this debate, and it does not support the inference drawn from it. Under a court judgment, private hospitals in Delhi built on public land must reserve 10 per cent of bed capacity and 25 per cent of outpatient capacity for patients from economically weaker sections. A legislative committee found extensive non-compliance, including named hospitals missing the quotas in every month of a year, a hospital registered for 102 beds found running 251, and six hospitals providing under 1 per cent of services free to those patients, with recovery orders issued against five hospitals.[6]
Two conditions must travel with that. The report is internally inconsistent, citing 15 per cent of inpatient services in one section against 10 per cent in another. And it makes no finding, and offers no data, connecting non-compliance to foreign or medical-tourism patients. It evidences that private hospitals under domestic access obligations were not meeting them. Using it to evidence medical tourism displacement would be a false attribution.
No empirical study measuring displacement of domestic patients by foreign patients was located for this entry. Searches for crowding-out, waiting times, bed occupancy and foreign-patient volumes returned conceptual and interview-based papers and work on reducing waiting times for medical tourists rather than for locals. That is a search result, not proof that no such study exists.

Sourcing note: the fact sheet, the two reviews, the comparative study, the multi-country interview study and the legislative committee report were opened and read on 9 October 2026, one study at abstract level as marked. The universal coverage figures are not attributed by their publisher to medical tourism and are given only as context. The legislative committee report is reported with the explicit statement that it makes no finding connecting non-compliance to foreign patients, because it is frequently cited as though it did. The reviews characterising the evidence are from 2010 and 2011 and are dated in the text; no later systematic review of this question was located.
