Implications for the NHS of inward and outward medical tourism: a policy and economic analysis using literature review and mixed-methods approaches

Bariatric surgery tourism in the COVID-19 era

Background

Since the start of the Covid-19 pandemic primary and secondary health care services in Northern Ireland have observed an increase in the number of patients who have had bariatric surgery outside of the UK. This study sought to estimate the frequency of bariatric surgery tourism and to audit indications, blood monitoring and medical complications.

Methods

All primary care centres within the Western Health Social Care Trust (WHSCT) were invited to document the number of patients undergoing bariatric surgery between January 1, 2017 and December 31, 2022. For one primary care centre, patients who underwent bariatric surgery were assessed against the National Institute of Health and Clinical Excellence (NICE) guideline indications for bariatric surgery. In addition, the blood monitoring of these patients was audited against the British Obesity and Metabolic Surgery Society (BOMSS) guidelines for up to two years following surgery. Medical contacts for surgical complications of bariatric surgery were recorded.

Results

Thirty-five of 47 (74.5%) GP surgeries replied to the survey, representing 239,961 patients among 325,126 registrations (73.8%). In the six year study period 463 patients had reported having bariatric surgery to their GP. Women were more likely to have had bariatric surgery than men (85.1% versus 14.9%). There was a marked increase in the number of patients undergoing bariatric surgery with each year of the study (p<0.0001 chi square for trend). Twenty-one of 47 patients (44.7%) evaluated in one primary care centre fulfilled NICE criteria for bariatric surgery. The level of three-month monitoring ranged from 23% (for vitamin D) to 89% (electrolytes), but decreased at two years to 9% (vitamin D) and 64% (electrolytes and liver function tests). Surgical complication prevalence from wound infections was 19% (9 of 44). Antidepressant medications were prescribed for 23 of 47 patients (48.9%).

Conclusions

The WHSCT has experienced a growing population of patients availing of bariatric surgery outside of the National Health Service. In view of this and the projected increase in obesity prevalence, a specialist obesity management service is urgently required in Northern Ireland.

Demographics and Trends for Inbound Medical Tourism in Germany for Orthopedic Patients before and during the COVID-19 Pandemic

Medical tourism is a rapidly growing sector of economic growth and diversification. However, data on the demographics and characteristics of the traveling patients are sparse. In this study, we analyzed the common demographic properties and characteristics of the inbound medical tourists seeking orthopedic medical care in Germany for the years 2010 to 2019 compared to a domestic group. At the same time, we examined how the COVID-19 pandemic outbreak of 2020 changed the field of medical tourism in Germany. Calculations were performed using administrative hospital data provided by the Federal Statistical Department of Germany. Data were analyzed from the years 2010 to 2020. A total of six elective orthopedic surgery codes (bone biopsy, knee arthroplasty, foot surgery, osteotomy, hardware removal, and arthrodesis) were identified as key service indicators for medical tourism and further analyzed. Factors including residence, sex, year, and type of elective surgery were modeled using linear regression analysis. Age and sex distributions were compared between patients living inside Germany (DE) or outside Germany (non-DE). Between 2010 and 2020, 6,261,801 orthopedic procedures were coded for the DE group and 27,420 key procedures were identified for the non-DE group. Medical tourists were predominantly male and significantly younger than the domestic population. The linear regression analysis of the OPS codes over the past years showed a significantly different slope between the DE and non-DE groups only for the OPS code "hardware removal". With the COVID-19 pandemic, an overall decline in performed orthopedic procedures was observed for the non-DE and the DE group. A significant reduction below the 95% prediction bands for the year 2020 could be shown for hardware removal and foot surgery (for DE), and for hardware removal, knee arthroplasty, foot surgery, and osteotomy (for non-DE). This study is the first to quantify inbound medical tourism in elective orthopedic surgery in Germany. The COVID-19 pandemic negatively affected many-but not all-areas of orthopedic surgery. It has to be seen how this negative trend will develop in the future.

Dental tourism and the risk of barotrauma and barodontalgia

Background and aim Dental tourism, which reflects the provision of health care services abroad, also includes a travelling component. Air travel after dental intervention may cause barotrauma and barodontalgia. This paper aimed to provide guiding principles regarding the minimal time interval between dental procedures and air travel to prevent these adverse effects.Methods A literature search was performed to reveal information with regards to complications related to flights following dental treatments. There is little research in this area and most of it has been conducted on the military aircrew population, which has different characteristics of flight and personnel than civilian commercial flights.Results The recommended time of flying is one week after most dental intervention and six weeks after a sinus lift procedure. The minimal time required between a procedure and flight is 24 hours after restorative treatment, 24-48 hours after simple extraction, 72 hours after nonsurgical endodontic procedure, surgical extraction, and implant placement, and at least two weeks after sinus lift procedure.Conclusions The provided guidelines may serve as a starting point for the clinician's decision-making. The tailoring of an individual treatment plan to the patient should take into consideration the patient's condition, dental procedure, complications and flight characteristics. Further research based on commercial flights is needed to formulate more accurate guidelines for the civilian population.

Possible Early Examples of Medical Tourism

Health tourism has hundreds of years of history, most notably in visitors traveling to thermal baths. Medical tourism, a type of health tourism, has rapidly expanded in the last quarter century by patients travelling abroad to health centers for medical treatment. Because of lack of records in ancient times, the history of tourism for actual medical treatment is unknown. In Ottoman archives, medical treatment consent forms of patients were officially documented. We analyzed these existing records to identify foreign citizens who came to the Ottoman Empire for medical treatment. In our screening of Konya Şer'iye registration records, we found medical consent forms for three non-Ottoman foreign citizens. All three patients had the same medical illness and came to Konya for medical treatment. Therefore we emphasized that those patients searched for the name of doctor who was an authority on that illness. This study indicates that medical tourism may have occurred well before the 20th century.

A Global Survey by the International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) on Perceptions of Bariatric Medical Tourism (BMT) by Health Professionals: Guidelines from IFSO for BMT

BACKGROUND

Bariatric medical tourism (BMT) is a rapidly expanding industry, with over 650 million people with obesity worldwide and total number rising by over 300% between 2003 and 2014. The overall health tourism industry is worth over $400 billion/year.

METHODS

International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) conducted a global survey to analyze the details of BMT and the perceptions of bariatric health care professionals (HCP) regarding BMT.

RESULTS

A total of 383 bariatric HCP's with experience of 272,548 procedures responded from 65 countries. Seventy-three percent of respondents had managed BMT patients, whilst low cost of surgery was felt to be the driving factor in 77% of cases. The USA contributed the most patients travelling for BMT with 11.6%. Twenty-four percent of respondents stated that they had no access to adequate notes regarding the patient's operation, whilst 12% felt BMT is associated with a higher mortality. Only 49% of respondents felt that IFSO guidelines were followed by the operating surgeon. Sleeve gastrectomy was the commonly offered surgery and an overall mean operation cost was $8716. Nearly 64% of respondents felt BMT needed better coordination between practitioners, whilst almost 85% of respondents supported the idea of a forum to facilitate safe BMT worldwide.

CONCLUSION

This IFSO survey has outlined the current BMT trends worldwide and highlighted areas of concern in the care of such patients. It has expanded our knowledge and should be used as a starting point to establish international forums to aid collaboration.

Medical Tourism Markets: Models of Sustainability. The Case of Spain and The Costa del Sol (Malaga)

The interest and relevance of medical tourism has increased significantly over the last few decades, and it has become a very lucrative source of income and profit for many firms. This paper analyses the sustainability of the medical tourism model in Spain in general, and in The Costa del Sol (Spain) in particular, in order to investigate the potential challenges that the domestic industry will face in the future. For this purpose, we first analysed the process of the globalization of health services and the main characteristics of the Spanish medical tourism industry (in terms of tourism and health services). Second, we examined the data availability on medical tourism for the cases of Spain, Andalusia and The Costa del Sol, and identified who travels, why, and for what reasons. The results show that Spain and The Costa del Sol offer high-quality medical and tourism facilities and services with very competitive prices, and with the high commitment and support of public local authorities, tourism and health providers, and universities. However, the lack of a real leadership, well-defined strategy, financial support, and specific training programs are considered to be crucial challenges for the near future. In addition to this, the novel coronavirus, the economic crisis, Brexit and the situation of British expats living in Spain and The Costa del sol are also discussed.

Going for brokerage: strategies and strains in commercial healthcare facilitation

BACKGROUND

The formation of domestic and global marketplaces during the past 50 years has opened up new commercial opportunities for third-party activity in healthcare systems. Commercial mediation of access to healthcare is one recent area of activity that sees companies and individuals offering to organise healthcare and travel in return for payment. With varying degrees of control over the location, type, cost and experiences of healthcare provisioning, these intermediaries occupy potentially influential positions in healthcare systems and yet much of their work is poorly understood.

METHODS

Drawing on social science theories of brokerage, this article presents a novel analysis of commercial healthcare facilitation. It focuses on facilitation companies and their workers as central, intermediating actors for people to access healthcare in markets characterised by complexity. Semi-structured interviews were conducted with people working in domestic and international healthcare facilitation in London and Delhi, and data were analysed using a framework approach that emphasises the structural features and personal agencies for this area of work.

RESULTS

Findings point to an institutional environment for commercial healthcare facilitation marked by competition and the threat of obsolescence. The activities of rivals, and the risk that users and providers will bypass intermediaries, compels facilitation companies to respond strategically and to continuously pursue new populations and activities to mediate - to go for broke. These pressures percolate into the lives of people who perform facilitation work and who describe a physical and mental burden of labour incurred by onerous processes for generating and completing facilitation work. The need for language interpretation services introduces an additional set of relations and has created further points of tension. It is an environment that engenders mistrust and anxiety, and which incentivises exploitation and a commodification of users whose associated commissions are highly prized.

CONCLUSION

Brokerage analysis provides valuable insights into the strategies and strains for commercial mediation of access to healthcare, and the findings indicate opportunities for further research on the contributions of interpreters, diplomatic and business networks, and new technologies, and on the growth of new forms of mediation in domestic and overseas settings.

The north-south policy divide in transnational healthcare: a comparative review of policy research on medical tourism in source and destination countries

Medical tourism occupies different spaces within national policy frameworks depending on which side of the transnational paradigm countries belong to, and how they seek to leverage it towards their developmental goals. This article draws attention to this policy divide in transnational healthcare through a comparative bibliometric review of policy research on medical tourism in select source (Canada, United States and United Kingdom) and destination countries (Mexico, India, Thailand, Malaysia and Singapore), using a systematic search of the Web of Science (WoS) database and review of grey literature. We assess cross-national differences in policy and policy research on medical tourism against contextual policy landscapes and challenges, and examine the convergence between research and policy. Our findings indicate major disparities in development agendas and national policy concerns, both between and among source and destination countries. Further, we find that research on medical tourism does not always address prevailing policy challenges, just as the policy discourse oftentimes neglects relevant policy research on the subject. Based on our review, we highlight the limited application of theoretical policy paradigms in current medical tourism research and make the case for a comparative policy research agenda for the field.

Diasporic medical tourism: a scoping review of quantitative and qualitative evidence

Background

There is a growing recognition of the significance of the diasporic dimension of medical travel. Explanations of medical tourism are increasingly presented in a wider context of transnationalism, diaspora and migration. Yet diaspora and cross-border travellers rarely get through the broader narrative of medical travel.

Objective

Our aim in this scoping review was to extend the current knowledge on the emerging subject of diasporic travels for medical purposes. Specifically, we reviewed the existing literature on what is known about the determinants and motivational factors of diasporic medical tourism; its geographic scope and its quantitative estimation.

Methods

Using a scoping review methodology, we conducted the search in seven electronic databases. It resulted in 210 records retrieved. Ultimately, 28 research papers and 6 non-research papers (published between 2002 and 2019) met the following criteria: 1) focus on healthcare and health-related practices, 2) transnational perspective, 3) healthcare consumption in the country of origin (homeland) while being a resident of another country, 4) published in English.

Results

The findings from our review highlighted the importance of diasporic medical patients who had been researched and analysed on four continents. Even though quantitative evidence has been scarce, the data analysed in the scoping review pointed to the existence of non-negligible level of diasporic medical tourism in Northern America, and in Europe. Various motivational factors were enumerated with their frequency of occurrence: medical culture (12), time availability (“by the way of being home”) (9), communication (6), dissatisfaction with the current system (6), healthcare insurance status (5), quality of healthcare (5), second opinion (3), and value for money (3).

Conclusion

Diasporic medical tourists constitute an attractive segment of consumers that is still not well understood and targeted. They are part of transnational communities that cultivate the links between the two nations. They simultaneously participate in bi-lateral healthcare systems via return visits which impact the health systems of sending and receiving countries in a substantial way. In the current globalised, connected and migratory context, transnationalism seems to represent an answer to many local healthcare-related barriers. Sending and receiving countries have put in place an array of programmes and policies addressed to the diasporic medical travellers.

Medical tourism trends in the United Kingdom 2000-2016

Purpose

The purpose of this study is to investigate the inbound and outbound medical tourism in the UK to determine if the UK can be considered as a net exporter of health services as well as the impact of the 2007 global economic crisis, diaspora populations and the number of UK expats on medical tourism figures.

Design/methodology/approach

Using microdata drawn from the International Passenger Survey (2000-2016), the authors estimate the flows, number of nights and expenditure of tourists looking for medical treatment who complete international visits of less than 12 months’ duration to and from the UK. The authors also analyse the main destinations of UK residents, the country of origin of overseas residents and the particular case of British expats.

Findings

The results show the upward trend of inbound and outbound patients, the strong seasonality in outbound patients, and the significant increase in the levels of expenditure of overseas residents since 2005. Poland, France, Hungary and India are the chosen countries by UK residents to be treated, whereas Irish Republic, Spain, France, Gibraltar and the United Arab Emirates are the main countries providing inbound health patients. However, the processes of migration explain full or partly the inbound and outbound flows found for some countries.

Originality/value

This study offers a critical insight into inbound and outbound medical flows, demonstrating both the scope for and limitations to market development in this area.

Report on Current Experience of ASAPS Membership and Management of Cosmetic Tourism Complications

Background

Cosmetic tourism is an expanding industry with increasing scrutiny in the public domain of complications and patient safety issues. The health and financial implications for patients are large and deserve further investigation.

Objectives

The aim of this study was to understand the experience of the American Society for Aesthetic Plastic Surgery (ASAPS) members treating medical tourism patients with complications who returned to the United States for secondary management.

Methods

A 20-question survey was administered electronically in August 2018 to ASAPS members with voluntary participation. Questions about surgeon experience, the nature of complications, type of initial surgery, and subsequent management were asked. Responses were tabulated and percentages of response choices were calculated and reported.

Results

Ninety-three responses were received from the 1611 physician ASAPS members (5.8% response rate). More than half of respondents had seen 2 to 5 patients in the last 12 months with a complication from cosmetic tourism. The most common procedure that patients had done abroad was abdominoplasty. The most common complication was infection caused by Gram-positive organisms, managed on an outpatient basis without surgical intervention. Involvement of an ASAPS member led to successful resolution of complications in the vast majority of patients. Estimated costs out of pocket for management of complications were most commonly between $1001 and 5000.

Conclusions

While the experience of ASAPS members is as varied as the complications faced by cosmetic tourism patients, the vast majority of complications is infectious and can be managed on an outpatient basis successfully with the involvement of an ASAPS member. Further collaborative efforts both domestically and internationally can help improve patient safety for cosmetic tourism patients.

Government roles in regulating medical tourism: evidence from Guatemala

Background

Regulation of the medical tourism and public health sectors overlap in many instances, raising questions of how patient safety, economic growth, and health equity can be protected. The case of Guatemala is used to explore how the regulatory challenges posed by medical tourism should be dealt with in countries seeking to grow this sector.

Methods

We conducted a qualitative case study of the medical tourism sector in Guatemala, through reviews and analyses of policy documents and media reports, key informant interviews (n = 50), and facility site-visits.

Results

Key informants were critical of the absence of effective public regulation of the emerging medical tourism sector, noting several regulatory gaps and the importance of filling them. These informants specifically expressed that: 1) The government should regulate medical tourism in Guatemala, thought there was disagreement as to which government sector should do so and how; 2) The government has not at this time regulated the medical tourism sector nor shown great interest in doing so; and 3) International accreditation could be used to augment domestic regulation.

Conclusions

The intersection of domestic and international regulation of medical tourism has been largely unexplored. This case study advances new research in this area. It highlights the need for and dearth of regulatory protections in Guatemala and lessons for other, similarly situated countries. National regulatory models from Israel and Barbados could be adapted to the Guatemalan context. Global governance could help to protect national governments from any competitive disadvantages created by regulation. Underlying the concerns over growth in medical tourism, however, is how it contributes to the ongoing privatization of health care facilities worldwide. This trend risks undermining efforts to reach targets for Universal Health Coverage and exacerbating existing inequities in the global distribution of health and wealth.

Experience of a specialist emergency bariatric surgical service

BACKGROUND

Bariatric surgery is associated with late and procedure-specific acute surgical complications. There is very little evidence available regarding the volume, nature, and outcomes of acute surgical admissions directly stemming from bariatric surgery. Centralization of bariatric elective services in the United Kingdom may have an adverse impact on the ability of local services to manage such unpredictable complications. To address this potential problem, we set up a comprehensive and specialist emergency bariatric service.

OBJECTIVES

The aim of this study was to quantify and characterize the workload of a specialist emergency surgical bariatric service.

SETTING

University National Health Service hospital.

METHODS

Over 2 years, we prospectively collected data on demographic characteristics, management, and outcomes of all acute surgical admissions related directly to previous bariatric surgery.

RESULTS

Between December 2011 and November 2013, 69 patients had 71 emergency admissions due to a surgical emergency directly related to previous bariatric surgery. Thirty-seven (54%) had undergone primary bariatric surgery at our institution, 13 (19%) at a different National Health Service hospital, 16 (23%) at private U.K. hospitals, and 3 (4%) at private overseas hospitals. Forty-four endoscopic or surgical interventions were required, of which 17 (39%) were performed on nights or weekends and within 12 hours of admission. Of 27 operations, 25 (93%) were completed laparoscopically. Median length of stay was 2 days, there were no mortalities, and there was 1 readmission within 30 days.

CONCLUSIONS

There is a significant volume of late bariatric surgical emergencies, many requiring urgent intervention. These may be effectively managed by a specialist bariatric service.

Cross-border-assisted reproduction: a qualitative account of UK travellers' experiences

Surveys on patients' experiences of cross-border fertility treatment have reported a range of positive and challenging features. However, the number of such studies is limited, and there is no detailed qualitative account of the experiences of UK patients who travel overseas for fertility treatment. The present study used a cross-sectional, qualitative design and in-depth interviews. Fifty-one participants (41 women and 10 men, representing 41 treatment 'cases') participated in semi-structured interviews. The experiences reported were broadly positive with a large proportion of participants (39 cases, 95%) citing a favourable overall experience with only two cases (5%) reporting a more negative experience. Thematic analysis revealed 6 major categories and 20 sub-categories, which described the positive and challenging aspects of cross-border fertility travel. The positive aspects were represented by the categories: 'access', 'control' and 'care and respect'. The more challenging aspects were categorized as 'logistics and coordination of care', 'uncertainty' and 'cultural dissonance'. The study confirms findings from others that despite some challenges, there is a relatively high level of patient satisfaction with cross-border treatment with participants able to extend the boundaries of their fertility-seeking trajectories and in some cases, regain a sense of control over their treatment.

Facilitating safe and successful cross-border healthcare in the European Union

OBJECTIVE

Even though medical travel is expanding, limited research has identified pitfalls along the full process of medical travel. This study explores the experiences of medical travellers, with a focus on potential issues that may threaten safe and effective medical travel.

METHODS

The experiences of medical travellers were assessed using a cross-sectional questionnaire in the Netherlands in 2014. The questionnaire (n=101) contained 52 items measuring the transfer of records, quality of care abroad, follow-up care, and reimbursement. Additionally, experts provided feedback on the pitfalls identified.

RESULTS

63.1% of medical records were not transferred in advance to the clinic abroad, and for 10.7% of cases these remained unknown during treatment. Although quality of care abroad was rated higher than in the home country, follow-up care was initially refused to 22.2% of patients. Additionally, patients reported problems related to reimbursement.

CONCLUSION

More effort is needed to facilitate safe medical travel. Medical professionals should be informed on procedures for medical travellers, especially concerning follow-up care and record transfers. Yet, medical travellers themselves are ultimately responsible for this transfer. Clear information on the necessity of this personal transfer, and clarification on reimbursement options and the authorisation procedure, should be provided by national contact points and third-party payers. Additionally, payment structures to care providers may need adjustments to cover costs of follow-up care.

Evidence on global medical travel

The potential benefits of travelling across national borders to obtain medical treatment include improved care, decreased costs and reduced waiting times. However, medical travel involves additional risks, compared to obtaining treatment domestically. We review the publicly-available evidence on medical travel. We suggest that medical travel needs to be understood in terms of its potential risks and benefits so that it can be evaluated against alternatives by patients who are seeking care. We propose three domains –quality standards, informed decision-making, economic and legal protection – in which better evidence could support the development of medical travel policies.

Stem cell tourism--a web-based analysis of clinical services available to international travellers

BACKGROUND

Stem cell therapies are advertised through online resources which describe a range of treatments with diverse clinical indications. Stem cell tourists may not be aware of the information they should seek when consulting these clinics, or of the potential risks involved. The aim of this study was to characterise the therapies offered by online stem cell clinics.

METHODS

A web based search utilising five search terms was employed. The first twenty pages of each search result were screened against 340 variables.

RESULTS

224 out of 1091 websites advertised stem cell clinics. 68 eligible sites covering 21 countries were evaluated. The top five clinical indications for stem cell therapy were multiple sclerosis, anti-ageing, Parkinson's disease, stroke and spinal cord injury. Adult, autologous stem cells were the most commonly utilised stem cell, and these were frequently sourced from bone marrow and adipose tissue and administered intravenously. Thirty-four per cent of sites mentioned the number of patients treated while one quarter of clinics provided outcome data. Twenty-nine per cent of clinics had an internationally recognised accreditation. Fifteen per cent of clinics stated that their therapies posed no risk. Eighty-eight per cent of clinics claimed treatment effectiveness, with 16% describing their curative potential. Over 40% of sites did not specify the number or duration of treatments. Fifty-three per cent of clinics requested access to patients' medical records, and 12% recommended patients discuss the proposed therapy with their doctor. No clinic recommended that travellers consult a travel medicine specialist or receive vaccinations prior to their intended travel. One quarter of sites discussed contraindications to treatment, with 41% of sites detailing follow up patient care.

CONCLUSIONS

There is potential for stem cell tourists to receive misleading or deficient information from online stem cell clinics. Both the stem cell tourist and travel medicine practitioner should be educated on the potential risks associated with stem cell clinical services advertised online.

Continuity across inpatient and outpatient mental health care or specialisation of teams? A systematic review

BACKGROUND

A central question for the organisation of mental health care is whether the same clinicians should be responsible for a patient's care across inpatient and outpatient settings (continuity of care) or if there should be separate teams (specialisation). Current reforms in Europe are inconsistent on which to favour, and are based on little research evidence. This review is the first systematic appraisal of the existing evidence comparing continuity of care and specialisation across inpatient and outpatient mental health care.

METHOD

A systematic search for studies of any design comparing mental health care systems based on continuity or specialisation of care was performed. Differences in clinical, social and cost-effective outcomes, and the views and experiences of patients and staff were assessed using narrative synthesis.

RESULTS

Seventeen studies met the inclusion criteria. All studies had methodological shortcomings, but findings point towards reduced length and number of hospitalisations, and faster or more flexible transitions between services in continuity systems. Survey and qualitative findings suggest advantages of both systems, whilst patients and staff appear to prefer a continuity system.

CONCLUSION

The evidence base suggests better outcomes and stakeholder preferences for continuity of care systems, but the quality of existing studies is insufficient to draw definitive conclusions. Higher quality comparative studies across various settings and population groups are urgently needed.
