Decision-making about bariatric and cosmetic medical tourism from countries with universal healthcare: a rapid systematic review.
Synthesis in Globalization and health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundA growing number of people are travelling abroad for medical treatments (known as medical tourism; MT), driven by globalisation of the healthcare market. Medical tourists from countries with universal healthcare strain resources when returning with complications which require aftercare or further treatment. This rapid systematic review synthesised literature on decision-making of medical tourists, focusing on cosmetic and bariatric MT as high-demand and high-risk areas, to identify opportunities to support informed decision-making (PROSPERO registration number: CRD420251000992).
methodsGuided by Cochrane guidance for rapid reviews, three databases (MEDLINE®, PsycINFO, and Web of Science) plus grey literature (Overton) were searched on the 24th February 2025 for qualitative, quantitative, or mixed methods studies that focused on outbound cosmetic or bariatric medical tourists from countries with universal healthcare. Narrative synthesis, thematic synthesis, and triangulation were applied. The Mixed Methods Appraisal Tool (MMAT) was used to assess the quality of included studies. Public involvement shaped the search methods and data interpretation.
resultsA total of 25 studies (12 qualitative, 11 quantitative, and two mixed methods) were included. Quantitative data indicated a primary motivator of cost. Thematic synthesis identified three overarching themes: (1) Medical Tourists as Constrained Consumers: Decision-Making under Systemic Healthcare Limitations, (2) Crowdsourcing Trust: Peer-Produced Evidence and Trusting Strangers in the Absence of Support, and (3) Informed but Invested: Navigating Risk Through Emotional Commitment. Triangulation identified quantitative research gaps particularly around information seeking behaviour and the effect of emotional investment on risk perception. DISCUSSION: Medical tourists are mainly limited in their decision-making by inaccessibility of universal healthcare and, subsequently, cost of treatment. Medical tourists are emotionally invested in receiving surgery, resulting in them minimising perceived risks. Medical tourists also rely heavily on anecdotal information, especially from online communities, in a context of inaccurate information and low social support. Prospective studies with generalisable samples are needed, particularly for bariatric tourism. Limitations include the limited value of available quantitative data in understanding the decision-making process of medical tourists.
conclusionsGiven the strong financial appeal of surgery abroad, efforts to reduce the harms of MT should prioritise harm reduction strategies over deterrence, which leverage the persuasive power of anecdotal evidence and strengthen communication with domestic healthcare providers.
