Introduction: Each year, millions of patients around the world seek medical care abroad. Medical travel is becoming very common in the Gulf Cooperation Council Countries (GCC) due to many motivational factors. It has been observed that the rate of cancer incidence is growing at an alarmingly high rate in Arab countries. In addition, as per the literature, cancer seems to be one of the top medical conditions for patients from the GCC to seek healthcare overseas. There are many factors associated with cancer patients seeking treatment overseas. However, unfortunately, there are very few studies that discuss the risks and challenges associated with the medical travel experience for those patients.
Objective: We conducted a systematic review to summarize the evidence related to the complications and challenges associated with the medical travel experience for oncology patients in the Arab world.
Materials and Methods: This systematic review was guided by PRISMA. PubMed was used as a search database by using a combination of medical travel, complications, and cancer keywords for publications which yielded 76 articles. Four coders independently determined eligibility based on PICOS and then extracted information from 14 articles. The resulting articles are based on three main categories, i.e., primary, and secondary data collection, and review articles.
Results: Of the total 76 articles, only 14 were included because they met the criteria. 62 articles were excluded because of irrelevance of the title, abstract, and insufficient data. Although this systematic review aimed to look at the medical complications that may arise from the medical travel experience for oncology patients, other challenges were found. The challenges reported can be grouped into the following themes: (a) financial and economic aspects, (b) medical care aspects, (c) social and cultural aspects.
Conclusion: Overall, more research studies are required in the Arab world for cancer patients treated overseas. The existence of such information around this topic will help in improving policies and strategies related to medical travel for the different stakeholders involved in the medical travel market. Moreover, these studies will not only aid in improving the quality of care for cancer patients who are engaging in medical travel, but they will also help in overcoming the challenges associated with medical travel experience for cancer patients at the different stages of the experience.

27.1.1 Background, Medical Travel, and Cancer
Medical travel is the practice of traveling abroad to seek healthcare services . This practice has been growing in developing countries and people travel seeking healthcare for different reasons . Since the Gulf Corporate Council countries are high-income countries, on many occasions’ governments cover their patients for seeking healthcare overseas. In the UAE, it is estimated that US$ 163 million was spent on treatment abroad for cancer care in 2013 . A recent study by Alnakhi, et al., (2019), which was conducted in the UAE shows that cancer is one of the three top medical conditions that triggered people to travel abroad seeking healthcare. Moreover, the same study showed the common destinations for seeking medical treatment among Emiratis were the UK, USA, India, and Thailand, with Germany being the top medical travel destination .
It has been noticed that the rate of cancer incidence is growing at an alarmingly high rate in Arab countries. According to the Global Cancer Observatory, there will be tremendous inflation in the cancer incidence rate from 4,63,675 in 2020 to 8,78,020 (around 1 million) by 2040 in 22 Arab countries .
Due to people’s perceptions of their healthcare system and sometimes the unavailability of the treatment domestically, many patients would prefer seeking healthcare services overseas. Although in the Gulf Region, there are many comprehensive cancer centers available such as in the UAE and the Kingdom of Saudi Arabia. However, patients and their families tend to seek a second opinion from advanced specialized regions abroad, despite the reassurances given by their local, American, or Canadian board qualified physicians (Fig. 27.1) .
27.2 Factors Associated with Treatment Abroad for Cancer Patients
There are multiple factors that cancer patients would consider when seeking treatment abroad. Some factors are directly related to socio-demographic characteristics and medical conditions, while the rest might be related to the treatment options offered to those patients overseas. Many factors are related to the healthcare systems or services in either patients’ home country or the treatment destinations.
Many factors contribute to patients’ decision-making, to receive medical care from other destinations. These factors include age, gender, degree of illness, marital status, academic, and income level [3, 5]. Motivations, perceptions, and experiences of the patients will differ by the type and the severity of cancer and whether the treatment had used surgical or medical management .
Treatment Options and Advanced Technology
Unavailability of specialized treatment in patients’ home country is one of the main reasons that push patients to treatment abroad. Moreover, the cost of the treatment and the treatment plan influence patients’ decision-making. Given that some patients are covered by their government or health insurance, while some patients pay out of their pockets [6,7,8].
Health System and Services
Quality of the healthcare services provided abroad, physician qualifications and experience, availability of specialized treatment, facility reputation, short waiting time, and skills of medical and administrative staff, all are factors that attract patients to seek treatment overseas. Source of information such as word of mouth from local physicians, family, and friends about the treatment destination are important factors to shape patients’ decisions to seek healthcare overseas. In many cases, even if the patients were treated domestically, they would consider overseas treatment for a second opinion [3, 6, 9].
27.3 Risks and Challenges Associated with Medical Travel and Cancer
There are insufficient up-to-date empirical studies that discuss complications and challenges which are associated with the medical travel experience of oncology patients, especially in the Arab world from patients’ perspectives. There is a scarcity of studies that looks in depth at the complications and challenges raised from the medical travel experience. In many scenarios, patients might face complications and challenges during or after receiving the treatment overseas. These challenges, if not tackled, could jeopardize patients’ health status and quality of life. Quality improvement measures and synergism between the health system of patients’ home country and treatment destination are necessary to ensure the best treatment plans are being given to patients. In addition, continuity of care with a proper follow-up care system and palliative care are vital to exist in the patient’s home country for best patient outcomes . This systematic review aims to summarize the evidence related to the complications and challenges associated with the medical travel experience for oncology patients in the Arab world.
A systematic narrative review was followed, which is according to Booth et al. (2012), a type of review where the literature is reviewed comprehensively and systematically . This methodology helps to descriptively summarize different study designs using summary tables. Additionally, it helps to identify any gaps in the literature. Narrative reviews are usually used to provide a general overview of the existing knowledge, the topic, and to guide the formation of follow-up research questions .
The systematic review was conducted in January 2021, and a total of 76 articles were retrieved. After reviewing the articles for eligibility through title and abstract; 23 articles were considered for full-text review, 53 were excluded. Out of 23 articles, 14 were included, and the remaining 9 articles were excluded. Figure 27.2 summarizes the search strategy and selection process using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statements .
27.4.1 Review Protocol
The review protocol is shown in Table 27.1. Several models can be used to guide the search method according to the review by Eriksen and Frandsen (2018) . In this review, PICOS (Population, Intervention, Comparator, Outcome, and Study type) model was used to guide the review process and key term selection.
27.4.2 Search Strategy
Search terms were used in PubMed. Terms appearing in the title and abstract were combined to search for articles that examined patients with malignancy, who traveled abroad and had complications. The scanning of articles through title and abstract was carried out by two groups of researchers (two in each group), who divided the list of articles into half. Each group of researchers reviewed the articles independently and eventually compared their findings with each other. When there is a non-agreement about eligibility, a third researcher is consulted for the final decision. In the second stage, the full-text articles were reviewed and the ones that met the inclusion criteria were included in the review.
27.4.3 Sources of Data
The search engines used for this literature review were limited to PubMed.
27.4.4 Inclusion Criteria
Only studies that were published in English and freely accessible were reviewed. The search was limited to articles published on or after the year 2000. No limits were made for the study design or the setting within which the study was undertaken.
27.4.5 Exclusion Criteria
Any study describing the pathophysiology, or the cost of the disease was excluded. Additionally, articles not discussing the complication or risks associated with traveling abroad for the management of malignancy were excluded.
27.4.6 Data Extraction and Data Synthesis
Data extraction and data synthesis were performed using narrative synthesis. Tables were used simultaneously to summarize group essential information and results about the included studies. The headings of the tables were formulated around the research questions.
27.5 Results and Discussion
Articles included in the review were classified into the following categories:
Articles based on primary data collection both qualitative study and quantitative study including, interviews, surveys, case studies.
Review articles: literature review and commentary.
Study based on secondary sources such as retrospective studies, and secondary data analysis.
The number of participants in the systematic review ranged from n = 1 participant in a case report review study to n = 6557 from administrative dataset. 4 out of 14 of the articles originated from the UAE. Patients traveled to different destinations around the world seeking healthcare services for cancer. Most patients in the systematic review were from Asia, the Mediterranean, and the Middle East regions. Cancer patients traveled seeking healthcare overseas for different reasons ranging from treatment, examination, screening, second opinion, and end-of-life care. Although some studies did not specify or report the type of cancer, patients in this review traveled for different types of cancers. Description of the articles reviewed and the challenges associated with medical travel experience are illustrated in Tables 27.2A and 27.2B.
In general, few studies and publications are discussing the risks and complications associated with medical travel, especially for oncology patients seeking treatment overseas. Although this systematic review aimed to look at the medical complications that may arise from the medical travel experience for oncology patients; other challenges were found. However, no details of medical challenges such as adverse events, medical errors, incidents, harms, or injuries were reported in these studies. The challenges reported in this systematic review can be grouped into the following themes: a) financial and economic aspects, b) medical care aspects c) social and cultural aspects.
27.5.1 Financial and Economic Aspects
Seeking treatment overseas might be associated with risk for financial distress. Financial distress may arise directly or indirectly. The direct financial risks are linked to the cost of treatment, whereas the indirect financial risks may arise due to the complications of the cancer treatment received overseas [3, 25, 26]. The main financial distress that was highlighted in this review originated from the patients, who are paying out of their pocket rather than those who are sponsored by their governments or insurance agencies. Skelton et al. (2020) discussed the financial distress of Iraqi patients who crossed the border to seek healthcare in Lebanon. Those patients had deficiencies in the healthcare in their home country with limited financial resources and had no choice other than to undergo cancer treatment in a neighboring country. The size of the financial distress increased with the repeated visits to the treatment destination . Other studies highlighted the financial burden of medical travel that impacted both patients and their families, especially with long-stay overseas [18, 19, 23]. On many occasions when patients’ companions are not sponsored, cancer patients will support their companions during their treatment journey. Moreover, Galloway, et al. (2020) reported that along with the cost of the travel, patients and their families may have other economic impacts such as missing paid work . In addition, problems with payment might arise post the treatment phase, when the expenses are not covered by patients’ insurance agencies .
27.5.2 Medical Care Aspects
Based on the findings of this review, challenges may arise at any stage of medical travel experience including pre, during, or post-treatment . In the pre-treatment stage, challenges were linked to incomplete referral documents, along with a lack of information. Information such as pathological findings, laboratory data, a summary of imaging, examination findings, and previous treatment are necessary to oncologists in the treatment destinations to provide a better course of treatment to cancer patients. Another challenge that may arise in this stage pertains to the timelines of treatment and travel. It is crucial to reduce the time between the initial diagnosis at the home country and receiving care at the treatment destinations [1, 16]. A delay in the pre-treatment phase might aggravate the patients’ case due to the rapid progress of cancer over time. It is worth mentioning that immunocompromised patients might be at risk of acquiring infection at any stage of medical travel .
During the treatment phase, oncology patients receive a variety of treatment options including chemotherapy, radiation, surgery, or palliative care based on the stage of cancer and the treatment plan. Unfortunately, on some occasions, treatment goals are not met in this phase due to complications, side effects, or misdiagnosis in the first place [6, 27].
Additionally, some risks may arise in the post-treatment phase. These risks are associated with returning home, especially when there is no continuation of the treatment or if no proper follow-up care plans. Follow-up care is a concern that was raised in other studies from patients who experienced medical care overseas [24, 28]. Although many cancer patients might be stable during the treatment phase, the health status of the patients might deteriorate after treatment and when patients arrive home, especially patients with unpredictable prognosis . On other occasions, patients might have difficulties committing to the treatment plan, whether during or after the treatment. Lack of coherence and planning in the treatment between patients’ home countries and treatment destinations, whether it is due to health system issues or other reasons such as the interruption that occurred during the COVID-19 era will influence the outcomes as discussed by Al-Shamsi, Humaid O., et al. (2020) .
27.5.3 Social and Cultural Aspects
Challenges with cultural and social aspects were reported in some of the included reviewed articles [1, 19, 23]. For example, the commentary by Al Shamsi, Al Hajeili, and Alrawi (2018) highlighted the issues of communication between healthcare providers and international patients that could arise due to cultural and language differences. There is a cultural difference regarding disclosing information to patients. Some families, for example, do not prefer and are concerned to disclose the diagnosis and prognosis to their patients to avoid psychological distress. This challenging ethical situation may create a conflict between health care providers and patients’ families particularly when healthcare providers do not take patients’ and their families’ culture into consideration in the treatment plan . Other challenges were discussed in the review related to miscommunication between patients and healthcare providers regarding pain severity and management. For instance, patients from a few cultures might hide their pain during the treatment journey which may cause inappropriate assessment and management of pain by healthcare providers.
Moreover, lack of cultural awareness about patients’ traditional ways of coping with illness, dying, and nonverbal communication was also stressed out in the reviewed article . On the other hand, the quality of interpretation was highlighted in some of the reviewed articles. This was exemplified in having unprofessional interpretation, assuming the role of an interpreter by a family member, or when the professional interpreters include their personal views and recommendations in the context which may lead to bias in the decision made by patients and their families around the treatment plan [1, 19].
Moreover, medical travel may cause a social burden. For example, in the study by Whittaker (2015) which aimed to describe the experience of outsourced patients and their families from the Gulf Cooperation Council, the study found that patients who stay for a long period overseas produce a considerable burden to their families who are supporting them . Some instrumental problems such as delaying in issuing the travel visa were pointed out. Young et al. (2019) argued that some patients experienced a delay in initiating the treatment due to the process of obtaining a traveling visa from the treatment destination which may not work in favor of the patient’s health status .
27.6 Strengths and Limitations
Despite the recent studies and publications about medical travel, there are no previous studies solely discussing the challenges and complications associated with medical travel, specifically for oncology patients whether on the international scope or in the Arab world. Therefore, this review can be considered the first systematic review that discusses the challenges and the issues faced by cancer patients during their medical travel experience. This chapter has identified three main aspects that can be addressed to overcome the challenges associated with medical travel in the future. These challenges can be tackled at the different stages of the medical travel experience to have better patient outcomes. In addition, implications from this review can guide future decision-making, and create quality improvement measures and actions related to the challenges associated with medical travel for oncology patients in the three main aspects.
It is also important to acknowledge the limitations of this review. One database was used for this study due to limited access to other databases. In the review, we found that many issues and challenges might accompany the medical travel experience and are not only directly associated with receiving the medical care service, as other aspects of cancer patients’ lives are also involved. In this review, we focused only on the challenges associated with the medical travel experience of oncology patients and did not consider the benefits that may come with the experience. Looking at both sides of the medical travel experience, positive and negative, might give a holistic and better picture of the experience. Only articles published in English were included in this review. Other languages and gray literature were not used for this review, although they might add more information to the topic. Due to the limited studies that discuss the challenges and issues of medical travel for cancer patients in the Arab world, it was difficult to narrow the scope of this review to the Arab world only.
In this chapter, we present the first study to systematically review challenges associated with medical travel for oncology patients seeking healthcare services outside their home country. Some challenges are associated with medical travel including economic and financial, medical care, and social and cultural challenges. In general, there is a scarcity of relevant studies that discuss this topic whether quantitatively, or qualitatively, especially in the Arab world. Such studies are vital to patients, healthcare providers, health insurance, health policymakers, and the different stakeholders involved in the medical travel market. Having sufficient information about the challenges associated with the medical travel experience will assist in creating better synergy between patients’ home countries and treatment destination’s healthcare systems when dealing with medical travelers. Overall, more research studies are required in this area to inform the different stakeholders involved in the medical travel field to analyze and overcome the challenges associated with this practice. Studies related to the risks and challenges associated with medical travel, will no doubt better characterize the risk profile associated with the medical travel industry at the different phases before, during, and after the medical travel experience for oncology patients.
