Introduction
World Health Organization guidelines on Palliative Care (PC) state that worldwide PC must suit the individuals’ cultural needs and context (Sepúlveda et al., Reference Sepúlveda, Marlin, Yoshida and Ullrich2002). Consequently, the PC needs of ethnic minorities, those who have specific cultural and socio-demographic characteristics, have gained increasing attention from service providers and researchers aimed at providing equitable PC services to all in society (Periyakoil et al., Reference Periyakoil, Neri and Kraemer2016; Randhawa and Owens, Reference Randhawa and Owens2004; Worth et al., Reference Worth, Irshad and Bhopal2009).
It has been documented that ethnic minorities in western countries have limited access to PC services (Ackroyd, Reference Ackroyd2003; Philips and Taylor, Reference Philips and Taylor2012; Worth et al., Reference Worth, Irshad and Bhopal2009). Among them, people originating from South Asia are one of the most significant and largest ethnic minorities in western countries (Gupta et al., Reference Gupta, Brister and Verma2006; Morency et al., Reference Morency, Malenfant and Maclsaac2017; SAALT, 2012). South Asian countries include Afghanistan, Bangladesh, Bhutan, India, Nepal, Pakistan, Sri Lanka, and the Maldives (Gupta et al., Reference Gupta, Brister and Verma2006; LeCroy and Stevens, Reference LeCroy and Stevens2017). South Asian migrants have been studied worldwide due to their higher burden of life-threatening diseases and chronic diseases compared to other ethnic groups (Nair and Prabhakaran, Reference Nair and Prabhakaran2012) resulting from their lifestyle, intense cultural values, and beliefs tied to their country of origin (Salant and Lauderdale, Reference Salant and Lauderdale2003; Tiwari and Wang, Reference Tiwari and Wang2008). In this review, the South Asian population will be referred to as a single group of people originating from the same continent, but still, it is important to recognize that the term, South Asians, represents a group, with a variety of languages, religions, and culture (Kristiansen et al., Reference Kristiansen, Irshad, Worth, Bhopal, Lawton and Sheikh2014; Worth et al., Reference Worth, Irshad and Bhopal2009).
Empirical research on South Asian migrants from the perspective of PC has been conducted within national contexts. However, we did not find a systematic review that accumulates the experiences (active participation in something) and perspectives (someone's view on something) on PC practices of older South Asian migrants in different countries. Therefore, this systematic review aims to systematically summarize and present the available international published literature on experiences with and perspectives on PC among older South Asian migrants, relatives, and healthcare providers. The terms, relatives and family members, are used interchangeably in this review, and healthcare providers (HPs) include, for example, nurses, physicians, chaplains, nurse administrators, social workers, priests, and interpreters. Definitions of different terms used in this review are listed in Table 1.
Methods
This review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. The protocol for this systematic review was registered with PROSPERO (CRD42018093464), an international prospective register of systematic reviews. Inclusion and exclusion criteria of the articles are listed in Table 2.
Studies were searched for in PubMed, EMBASE, CINAHL, and PsychINFO databases in February 2018, covering the period from 2000 to 2018. Studies published after 2000 were included to ensure that the results reflect current practice. With the assistance of an experienced information specialist, a search strategy was developed. Considering the aim, three focus areas were targeted for relevant studies: migrants, South Asian geographical area, and palliative care; combined with AND to retrieve relevant studies. The search profile used in PubMed is provided as an example of the strategy used (Table 3). In addition, the reference lists of reviewed articles were searched manually. Full texts of the articles were reviewed to discover if any of the titles in the reference list seemed relevant.
Data was extracted using a form developed for this review on study aim, author, country, study design, sample size, and main findings (Table 4). Articles were screened, read, and analyzed by J.S., afterwards overseen by M.R. Disagreement on selection, eligibility, and quality of articles were discussed and agreed upon subsequently.
*Terms in the table are expressed as it was mentioned in the original article
Each study was evaluated for methodological quality. Studies were graded by the scheme developed by Hawker et al. (Reference Hawker, Payne, Kerr, Hardey and Powell2002), because it provides a comprehensive and consistent framework to assess the quality of the entire research process and enables comparison of studies applying heterogeneous approaches. Ten areas were scored (title and abstract; introduction and aims; method and data; sampling; data analysis: ethics; bias; results; transferability and generalizability; and implications and usefulness). Each area was awarded grades ranging from 1 (very poor) to 4 (very good). The scale provides a maximum score of 40 and a minimum score of 10.
Analysis
A content analysis was performed to identify the main themes of the included studies (Elo and Kyngäs, Reference Elo and Kyngäs2008; Morris et al., Reference Morris, King, Turner and Payne2015). Result and discussion parts of the studies were read and consequently coded. Similar codes were grouped systematically and identified sub-themes were listed. Thematic syntheses of the similar themes were grouped together under overarching themes (Table 5).
Results
A total of 1,031 articles were retrieved from the searches, of which 28 met inclusion criteria. Two more studies were obtained from the reference lists. A total of 30 studies were included in this review. The detailed selection process is shown in Figure 1, including reasons for exclusion. Descriptions of included studies are presented in Table 3. Thirty studies were graded for methodological rigor and scores awarded ranged from 23 to 39 out of 40 (Table 3).
This review included studies undertaking a range of methodologies: 24 qualitative, five quantitative, and one mixed method design. We did not find any review and/or meta-analysis that described South Asian migrants’ perspectives and experiences on PC. The number of studies from each of the following countries was as follows: United Kingdom (UK) – 16, United States of America (USA) – 6, Australia – 3, Canada – 3, and Scotland – 2. Three main religious beliefs were discussed in the articles: Hindu, Muslim, and Sikh. The analysis revealed three themes, each with two sub-themes: 1) the PC practice within the family, 2) trust as prediction for PC, and 3) importance of knowledge and cultural competency.
1. The PC practice within the family
The literature search revealed studies discussing both the formal (professional) and informal (family) practice of PC in the migrant families. Fourteen studies raised the concern about preferred place of death and receiving care (Chattoo and Ahmad, Reference Chattoo and Ahmad2008; Coupland et al., Reference Coupland, Madden, Jack, Moller and Davies2011; Cowan, Reference Cowan2014; Khosla et al., Reference Khosla, Washington and Regunath2016; Owens and Randhawa, Reference Owens and Randhawa2004; Radhakrishnan et al., Reference Radhakrishnan, Saxena, Jillapalli, Jang and Kim2017; Randhawa and Owens, Reference Randhawa and Owens2004; Shanmugasundaram and O'Connor, Reference Shanmugasundaram and O'Connor2009; Sharma et al., Reference Sharma, Khosla, Tulsky and Carrese2012; Venkatasalu, Reference Venkatasalu2017; Venkatasalu et al., Reference Venkatasalu, Seymour and Arthur2014; Weerasinghe and Maddalena, Reference Weerasinghe and Maddalena2016; Wilkinson, Waqar, et al., Reference Wilkinson, Waqar and Gill2017; Worth et al., Reference Worth, Irshad and Bhopal2009). According to these studies, preference was dependent on the interplay of various factors, for example, finance (Venkatasalu et al., Reference Venkatasalu, Seymour and Arthur2014), availability of caregivers at home (Cowan, Reference Cowan2014), mistrust in institutional care (Venkatasalu, Reference Venkatasalu2017; Weerasinghe and Maddalena, Reference Weerasinghe and Maddalena2016), and the opportunity to perform religious practices (Venkatasalu, Reference Venkatasalu2017; Venkatasalu et al., Reference Venkatasalu, Seymour and Arthur2014).
1.1. Dying at home or in hospital
Home was considered the preferred place of care and death in several studies (Cowan, Reference Cowan2014; Doorenbos, Reference Doorenbos2003; Venkatasalu, Reference Venkatasalu2017; Venkatasalu et al., Reference Venkatasalu, Seymour and Arthur2014; Weerasinghe and Maddalena, Reference Weerasinghe and Maddalena2016), as patients felt happier at home (Cowan, Reference Cowan2014). Some older migrants expressed their wish to go back to their homeland (country of birth) to die a peaceful death (Cowan, Reference Cowan2014). Spending the last days of life in one's homeland was preferable in terms of safety, space, time, caring persons, and practicing rituals surrounding death (Radhakrishnan et al., Reference Radhakrishnan, Saxena, Jillapalli, Jang and Kim2017; Venkatasalu et al., Reference Venkatasalu, Seymour and Arthur2014).
Studies underlined that being cared for and to die in one's home was related to privacy (Shanmugasundaram and O'Connor, Reference Shanmugasundaram and O'Connor2009), cleanliness, performing rituals, and most importantly, being surrounded by family (Chattoo and Ahmad, Reference Chattoo and Ahmad2008; Venkatasalu, Reference Venkatasalu2017; Venkatasalu et al., Reference Venkatasalu, Seymour and Arthur2014). According to one study, while a person dies at home, he/she can complete responsibilities toward family, and relatives can show their respect toward the dying person (Venkatasalu et al., Reference Venkatasalu, Seymour and Arthur2014). Another study mentioned that lack of culturally sensitive care in the hospital causes dissatisfaction among caregivers, which shifted the choice to home as the place of death (Weerasinghe and Maddalena, Reference Weerasinghe and Maddalena2016). Despite the desire for comfort and peace from dying at home, due to the practicalities of older migrants living in the UK, many compromise and feel their death can be better managed in hospitals (Venkatasalu et al., Reference Venkatasalu, Seymour and Arthur2014). According to older migrants, dying at home could be complicated (Radhakrishnan et al., Reference Radhakrishnan, Saxena, Jillapalli, Jang and Kim2017) and care could be an unbearable burden (Venkatasalu, Reference Venkatasalu2017), often for their busy children (Venkatasalu et al., Reference Venkatasalu, Seymour and Arthur2014).
1.2. Family caregivers
According to relatives, family care was named as the best option to retain dignity and comfort of the patients near death (Venkatasalu, Reference Venkatasalu2017). Within families, most caregivers were female (children/ daughters-in-law, and spouses of the ill patient) (Chattoo and Ahmad, Reference Chattoo and Ahmad2008; Cowan, Reference Cowan2014; Somerville, Reference Somerville2001). For caregivers, the main motivation for the caring role was love (Chattoo and Ahmad, Reference Chattoo and Ahmad2008), respect, religious reward, (Chattoo and Ahmad, Reference Chattoo and Ahmad2008; Cowan, Reference Cowan2014) and/or responsibility toward parents (Chattoo and Ahmad, Reference Chattoo and Ahmad2008; Cowan, Reference Cowan2014; Radhakrishnan et al., Reference Radhakrishnan, Saxena, Jillapalli, Jang and Kim2017; Sharma et al., Reference Sharma, Khosla, Tulsky and Carrese2012) which often led to a decline in help from outside of the family (Somerville, Reference Somerville2001). Moreover, fear of being criticized by the same community restricted seeking professional help for the dying relative (Worth et al., Reference Worth, Irshad and Bhopal2009).
Studies mentioned that the caregiving role at home was physically, mentally, and financially burdensome for relatives (Chattoo and Ahmad, Reference Chattoo and Ahmad2008; Shanmugasundaram and O'Connor, Reference Shanmugasundaram and O'Connor2009; Somerville, Reference Somerville2001; Wilkinson et al., Reference Wilkinson, Randhawa and Brown2014). Often, family caregivers (mostly women) were struggling to manage household activities on top of caring for the dying relative at home (Somerville, Reference Somerville2001; Shanmugasundaram, Reference Shanmugasundaram2015). Despite the extra burden, relatives were willing to care partly to avoid the extra cost of private care or just as a sign of being hopeful of possible recovery (Cowan, Reference Cowan2014; Shanmugasundaram and O'Connor, Reference Shanmugasundaram and O'Connor2009; Wilkinson et al., Reference Wilkinson, Randhawa and Brown2016). Often, caregivers used to ignore their own physical health and struggled with normal life due to the demands of their role as caregivers (Chattoo and Ahmad, Reference Chattoo and Ahmad2008; Shanmugasundaram, Reference Shanmugasundaram2015; Somerville, Reference Somerville2001). Religious beliefs were found to be a common coping resource used by family caregivers (Khosla et al., Reference Khosla, Washington, Shaunfield and Aslakson2017; Kristiansen et al., Reference Kristiansen, Irshad, Worth, Bhopal, Lawton and Sheikh2014; Somerville, Reference Somerville2001).
Older South Asian migrants trusted in the culture of shared decision making by involving other relatives (Chattoo and Ahmad, Reference Chattoo and Ahmad2008; Cowan, Reference Cowan2014; Ebrahim et al., Reference Ebrahim, Bance and Bowman2011; Venkatasalu et al., Reference Venkatasalu, Arthur and Seymour2013; Weerasinghe and Maddalena, Reference Weerasinghe and Maddalena2016). Perhaps the eldest son held the role of decision maker in the family (Biondo et al., Reference Biondo, Kalia, Khan, Asghar, Banerjee, Boulton and Simon2017; Ebrahim et al., Reference Ebrahim, Bance and Bowman2011; Radhakrishnan et al., Reference Radhakrishnan, Saxena, Jillapalli, Jang and Kim2017; Sharma et al., Reference Sharma, Khosla, Tulsky and Carrese2012). Therefore, older migrants never felt the need to discuss palliative care issues in advance (Venkatasalu et al., Reference Venkatasalu, Arthur and Seymour2013). In the US, children often avoided discussing the topic of Advanced Care Planning (ACP) in fear of upsetting their parents (Radhakrishnan et al., Reference Radhakrishnan, Saxena, Jillapalli, Jang and Kim2017). Studies revealed that having collective decision making and filial responsibility within the family was hampering the completion of ACP among Hindus living in the US (Doorenbos, Reference Doorenbos2003; Radhakrishnan et al., Reference Radhakrishnan, Saxena, Jillapalli, Jang and Kim2017). However, due to the busy daily life of children in the Western world, some parents started to realize the need for discussing palliative care issues in advance (Radhakrishnan et al., Reference Radhakrishnan, Saxena, Jillapalli, Jang and Kim2017). Compared to older generations, younger generations and woman were more willing to discuss palliative care issues in advance to avoid difficulties in the future (Biondo et al., Reference Biondo, Kalia, Khan, Asghar, Banerjee, Boulton and Simon2017; Doorenbos and Nies, Reference Doorenbos and Nies2003).
2. Trust as precondition for PC
The need for building trusting relationships among healthcare providers (HPs) and migrant families was mentioned in ten studies (Ackroyd, Reference Ackroyd2003; Cowan, Reference Cowan2014; Doorenbos, Reference Doorenbos2003; Khosla et al., Reference Khosla, Washington and Regunath2016; Khosla et al., Reference Khosla, Washington, Shaunfield and Aslakson2017; Radhakrishnan et al., Reference Radhakrishnan, Saxena, Jillapalli, Jang and Kim2017; Venkatasalu, Reference Venkatasalu2017; Venkatasalu et al., Reference Venkatasalu, Arthur and Seymour2013; Wilkinson, Waqar, et al., Reference Wilkinson, Waqar and Gill2017; Worth et al., Reference Worth, Irshad and Bhopal2009). Despite this, a lack of trusting relationships with migrant families and the HP were often reported (Cowan, Reference Cowan2014; Doorenbos, Reference Doorenbos2003; Venkatasalu, Reference Venkatasalu2017).
2.1. Trusting the staff
Patients and their families found themselves discriminated against during PC services of the host country in relation to their ethnic identity (Wilkinson et al., Reference Wilkinson, Randhawa and Brown2016). Although, studies did show that HPs with cultural and religious sensitivity were really appreciated by migrant families (Ackroyd, Reference Ackroyd2003; Owens and Randhawa, Reference Owens and Randhawa2004). Some studies discussed the importance of partnership among HPs, patients, families, and community (Venkatasalu, Reference Venkatasalu2017; Weerasinghe and Maddalena, Reference Weerasinghe and Maddalena2016; Worth et al., Reference Worth, Irshad and Bhopal2009), while others described the importance of an individual approach (Randhawa and Owens, Reference Randhawa and Owens2004) to building trustworthy relationships.
Patients and their relatives were afraid that staying in the hospital (Radhakrishnan et al., Reference Radhakrishnan, Saxena, Jillapalli, Jang and Kim2017; Venkatasalu, Reference Venkatasalu2017) or hospice care (Weerasinghe and Maddalena, Reference Weerasinghe and Maddalena2016) would make them feel alone. In addition, a lack of trust in hospital staff (Venkatasalu, Reference Venkatasalu2017), perceived prejudice from HPs in regards to rudeness, and cultural insensitivity (Weerasinghe and Maddalena, Reference Weerasinghe and Maddalena2016; Worth et al., Reference Worth, Irshad and Bhopal2009) restricted the wish to be cared for in hospitals among South Asian families (Worth et al., Reference Worth, Irshad and Bhopal2009). According to family caregivers, hospital staff ignored and failed to meet the physical and hygienic needs of their dying relatives (Venkatasalu, Reference Venkatasalu2017). Mistrust was also expressed by older persons when having White ethnics as their personal caregiver in hospital (Worth et al., Reference Worth, Irshad and Bhopal2009). They believed White personal caregivers would not have the sense of privacy, cleanliness, and overall understanding of South Asian culture (Worth et al., Reference Worth, Irshad and Bhopal2009). Subsequently, dissatisfaction with hospital care led to mistrust of care in the hospice setting as well (Venkatasalu, Reference Venkatasalu2017). However, previous positive experiences motivated people to be cared for in hospital (Radhakrishnan et al., Reference Radhakrishnan, Saxena, Jillapalli, Jang and Kim2017). Hospice care was really appreciated if it provided appropriate food, prayer facilities, Asian TV channels, and support for families and care after bereavement (Worth et al., Reference Worth, Irshad and Bhopal2009). Studies reported that South Asian families often expected to feed their relatives until the very end. Otherwise, they were not satisfied with the service (Venkatasalu, Reference Venkatasalu2017; Weerasinghe and Maddalena, Reference Weerasinghe and Maddalena2016).
2.2. Language barriers and building up trust
It was revealed that often patients themselves were willing to discuss PC. However, they were not able to due to language barriers (Wilkinson, Waqar, et al., Reference Wilkinson, Waqar and Gill2017). Older migrants were more likely to communicate in their own language although they could speak the language of the host country (Randhawa et al., Reference Randhawa, Owens, Fitches and Khan2003). To mitigate the language barrier, interpreters (in person or over the telephone) have been used in PC (Khosla et al., Reference Khosla, Washington, Shaunfield and Aslakson2017). The role of the interpreter was praised by the patients and their families only if he/she was skilled (Somerville, Reference Somerville2001; Wilkinson et al., Reference Wilkinson, Randhawa and Brown2016). On some occasions, even HPs expressed their lack of trust toward interpreters (Khosla et al., Reference Khosla, Washington, Shaunfield and Aslakson2017). It was also challenging for the HP to access and manage an interpreter on short notice (Wilkinson et al., Reference Wilkinson, Randhawa and Brown2016; Worth et al., Reference Worth, Irshad and Bhopal2009). Unavailability of interpreters (Randhawa et al., Reference Randhawa, Owens, Fitches and Khan2003) or family restriction led relatives to act as interpreter (Wilkinson et al., Reference Wilkinson, Randhawa and Brown2014) to maintain family privacy (Khosla et al., Reference Khosla, Washington, Shaunfield and Aslakson2017; Wilkinson, Waqar, et al., Reference Wilkinson, Waqar and Gill2017). Often as an interpreter, relatives modified, omitted, or miscommunicated to withhold medical information to protect patients or vice versa (Randhawa et al., Reference Randhawa, Owens, Fitches and Khan2003; Worth et al., Reference Worth, Irshad and Bhopal2009). Availability of link workers was valued as they had language skills as well as a religious and cultural understanding (Ackroyd, Reference Ackroyd2003). Link workers increased referrals to PC, facilitated communication, and maintained the link between the local community and the hospital (Ackroyd, Reference Ackroyd2003). However, there was a fear of breaking family privacy through the link worker who was often from the same community (Owens and Randhawa, Reference Owens and Randhawa2004; Randhawa et al., Reference Randhawa, Owens, Fitches and Khan2003).
It was suggested by one study that appointing more HPs from South Asian ethnic backgrounds can help to build trusting relationships (Randhawa et al., Reference Randhawa, Owens, Fitches and Khan2003). HPs with the same backgrounds speak the same language and have cultural and religious understanding (Randhawa et al., Reference Randhawa, Owens, Fitches and Khan2003; Somerville, Reference Somerville2001). HPs were suggested for identifying a spokesperson within the family and being persistent in delivering care to build a trustworthy relationship with migrant families (Khosla et al., Reference Khosla, Washington, Shaunfield and Aslakson2017; Randhawa and Owens, Reference Randhawa and Owens2004; Venkatasalu, Reference Venkatasalu2017).
3. Importance of knowledge and cultural competency
Twenty studies identified the issue of limited knowledge and partial awareness of PC as a term and of existing services available to the South Asian ethnic minority families (Biondo et al., Reference Biondo, Kalia, Khan, Asghar, Banerjee, Boulton and Simon2017; Bowling et al., Reference Bowling, Iliffe, Kessel and Higginson2010; Chattoo and Ahmad, Reference Chattoo and Ahmad2008; Cowan, Reference Cowan2014; Doorenbos, Reference Doorenbos2003; Ebrahim et al., Reference Ebrahim, Bance and Bowman2011; Khosla et al., Reference Khosla, Washington and Regunath2016; Owens and Randhawa, Reference Owens and Randhawa2004; Radhakrishnan et al., Reference Radhakrishnan, Saxena, Jillapalli, Jang and Kim2017; Randhawa and Owens, Reference Randhawa and Owens2004; Randhawa et al., Reference Randhawa, Owens, Fitches and Khan2003; Shanmugasundaram, Reference Shanmugasundaram2014; Shanmugasundaram and O'Connor, Reference Shanmugasundaram and O'Connor2009; Somerville, Reference Somerville2001; Venkatasalu et al., Reference Venkatasalu, Seymour and Arthur2014; Weerasinghe and Maddalena, Reference Weerasinghe and Maddalena2016; Wilkinson et al., Reference Wilkinson, Randhawa and Brown2016; Wilkinson et al., Reference Wilkinson, Randhawa and Brown2014; Wilkinson, Waqar, et al., Reference Wilkinson, Waqar and Gill2017; Worth et al., Reference Worth, Irshad and Bhopal2009), which in turn affected access to and use of PC services.
3.1. Lack of knowledge and communication
The issue of poor knowledge was complicated by the lack of cultural equivalent words for palliative care and hospice care. Moreover, often these words were negatively connected to death (Cowan, Reference Cowan2014; Randhawa and Owens, Reference Randhawa and Owens2004; Worth et al., Reference Worth, Irshad and Bhopal2009). One study revealed that better knowledge on available PC services was positively related to better cultural integration in the host country (Doorenbos, Reference Doorenbos2003). The same study reported that migrant families with longer stays in the host country had better language skills and consequently better integration (Doorenbos, Reference Doorenbos2003), although better integration did not always reflect the western way of PC decision making (Sharma et al., Reference Sharma, Khosla, Tulsky and Carrese2012). Yet compared to older people, younger people generations had better knowledge and more willingness to look for what more was offered within PC services (Randhawa et al., Reference Randhawa, Owens, Fitches and Khan2003; Sharma et al., Reference Sharma, Khosla, Tulsky and Carrese2012).
Nineteen studies identified the issue of communication between South Asian migrant patients/families and their HPs in PC (Ackroyd, Reference Ackroyd2003; Biondo et al., Reference Biondo, Kalia, Khan, Asghar, Banerjee, Boulton and Simon2017; Doorenbos, Reference Doorenbos2003; Khosla et al., Reference Khosla, Washington and Regunath2016; Khosla et al., Reference Khosla, Washington, Shaunfield and Aslakson2017; Owens and Randhawa, Reference Owens and Randhawa2004; Radhakrishnan et al., Reference Radhakrishnan, Saxena, Jillapalli, Jang and Kim2017; Randhawa and Owens, Reference Randhawa and Owens2004; Randhawa et al., Reference Randhawa, Owens, Fitches and Khan2003; Shanmugasundaram and O'Connor, Reference Shanmugasundaram and O'Connor2009; Sharma et al., Reference Sharma, Khosla, Tulsky and Carrese2012; Somerville, Reference Somerville2001; Venkatasalu et al., Reference Venkatasalu, Arthur and Seymour2013; Weerasinghe and Maddalena, Reference Weerasinghe and Maddalena2016; Wilkinson et al., Reference Wilkinson, Randhawa and Brown2016; Wilkinson, Randhawa, et al., Reference Wilkinson, Randhawa and Brown2017; Wilkinson et al., Reference Wilkinson, Randhawa and Brown2014; Wilkinson, Waqar, et al., Reference Wilkinson, Waqar and Gill2017; Worth et al., Reference Worth, Irshad and Bhopal2009). Communication was identified as the key and most crucial factor in access to PC (Randhawa and Owens, Reference Randhawa and Owens2004). Perhaps difficulties in communication were often increased by social patterns and family structures within South Asian migrant societies. Due to the gatekeeping nature of families (Wilkinson et al., Reference Wilkinson, Randhawa and Brown2016; Wilkinson et al., Reference Wilkinson, Randhawa and Brown2014; Wilkinson, Waqar, et al., Reference Wilkinson, Waqar and Gill2017), direct communication between patient and HPs was often missing (Wilkinson, Waqar, et al., Reference Wilkinson, Waqar and Gill2017). According to HPs, patients were reluctant to state their own wishes in front of other relatives (Khosla et al., Reference Khosla, Washington, Shaunfield and Aslakson2017). Moreover, communication about the care was interrupted by the involvement of multiple relatives and friends. Consequently, it was complicated for the HPs to identify a particular spokesperson (Khosla et al., Reference Khosla, Washington, Shaunfield and Aslakson2017; Wilkinson et al., Reference Wilkinson, Randhawa and Brown2014). Therefore, relatives with knowledge of health-related issues could work as mediators between HPs and other family members (Weerasinghe and Maddalena, Reference Weerasinghe and Maddalena2016). Although involving relatives facilitated communication between HPs and family members (Wilkinson, Randhawa, et al., Reference Wilkinson, Randhawa and Brown2017), communication barriers also existed within the patients’ family (Somerville, Reference Somerville2001). Relatives found it difficult to communicate the poor prognosis of the patient to other family members who knew less about the trajectory as a whole (Somerville, Reference Somerville2001). Apart from family, communication was also influenced by the patients’ gender preferences for HPs (Khosla et al., Reference Khosla, Washington, Shaunfield and Aslakson2017; Weerasinghe and Maddalena, Reference Weerasinghe and Maddalena2016) and link workers (Randhawa et al., Reference Randhawa, Owens, Fitches and Khan2003). According to HPs, older South Asian migrant patients and their families were not really interactive with the opposite gender (Khosla et al., Reference Khosla, Washington, Shaunfield and Aslakson2017). It was also suggested that the HPs should use less jargon while communicating with the migrant families (Khosla et al., Reference Khosla, Washington, Shaunfield and Aslakson2017).
Several other factors were identified as reasons for not discussing PC with/within the family: culture (Radhakrishnan et al., Reference Radhakrishnan, Saxena, Jillapalli, Jang and Kim2017; Venkatasalu et al., Reference Venkatasalu, Arthur and Seymour2013), religion (Khosla et al., Reference Khosla, Washington, Shaunfield and Aslakson2017), ethnicity (Biondo et al., Reference Biondo, Kalia, Khan, Asghar, Banerjee, Boulton and Simon2017), and/or poor language skill (Wilkinson, Waqar, et al., Reference Wilkinson, Waqar and Gill2017). Although, one study contradicts this by stating that nothing but poor education among the group of ethnic minorities hinders the discussion (Wilkinson et al., Reference Wilkinson, Randhawa and Brown2016). Studies mentioned that discussions about death and dying were related to diminishing hope and would possibly hasten the process of dying (Biondo et al., Reference Biondo, Kalia, Khan, Asghar, Banerjee, Boulton and Simon2017; Ebrahim et al., Reference Ebrahim, Bance and Bowman2011; Venkatasalu et al., Reference Venkatasalu, Arthur and Seymour2013; Wilkinson et al., Reference Wilkinson, Randhawa and Brown2016). To avoid the discussion, relatives wanted HPs to withhold discussion of a life-threatening diagnosis in front of the patient (Somerville, Reference Somerville2001; Weerasinghe and Maddalena, Reference Weerasinghe and Maddalena2016; Wilkinson et al., Reference Wilkinson, Randhawa and Brown2016). However, provision of inaccurate information to the patient contradicted patients’ autonomy (Weerasinghe and Maddalena, Reference Weerasinghe and Maddalena2016). Thus, restricting the discussion on PC consequently led to a lack of knowledge about available PC services (Khosla et al., Reference Khosla, Washington, Shaunfield and Aslakson2017). To improve awareness among patients and their families’, emphasis was given on the provision of information, advice, and knowledge toward them (Wilkinson, Waqar, et al., Reference Wilkinson, Waqar and Gill2017). The provision of information could be in the form of leaflets, posters, television programs, video, or audiocassettes in different South Asian languages (Randhawa and Owens, Reference Randhawa and Owens2004; Randhawa et al., Reference Randhawa, Owens, Fitches and Khan2003).
3.2. Cultural competence among healthcare professionals and its significance
Providing care with cultural knowledge has been presented in several terms: cultural competency (Khosla et al., Reference Khosla, Washington, Shaunfield and Aslakson2017; Owens and Randhawa, Reference Owens and Randhawa2004; Randhawa and Owens, Reference Randhawa and Owens2004; Wilkinson et al., Reference Wilkinson, Randhawa and Brown2016), cultural sensitivity (Weerasinghe and Maddalena, Reference Weerasinghe and Maddalena2016; Worth et al., Reference Worth, Irshad and Bhopal2009), culture appropriate (Radhakrishnan et al., Reference Radhakrishnan, Saxena, Jillapalli, Jang and Kim2017), and cultural awareness (Worth et al., Reference Worth, Irshad and Bhopal2009). Studies urged the need for cultural education and training among HPs to facilitate access to services and to mitigate inequalities in care (Randhawa and Owens, Reference Randhawa and Owens2004; Worth et al., Reference Worth, Irshad and Bhopal2009). Still, one study raised the issue that HPs were not aware of the available training (Worth et al., Reference Worth, Irshad and Bhopal2009). HPs with an understanding of the South Asian cultural context showed a positive influence during communication with individual patients and their families (Khosla et al., Reference Khosla, Washington, Shaunfield and Aslakson2017). HPs were concerned that they found it difficult to understand the culture and communicate, while at the same time, provide PC services toward South Asian migrant families (Owens and Randhawa, Reference Owens and Randhawa2004). Consensus was missing among HPs at different levels of PC concerning the proper time to start discussions on PC in the disease course and disclosure of illness to patients (Wilkinson et al., Reference Wilkinson, Randhawa and Brown2016). The misunderstandings were the result of time constraints, lack of confidence, skill, and cultural understanding in talking to patients and their families about PC (Radhakrishnan et al., Reference Radhakrishnan, Saxena, Jillapalli, Jang and Kim2017; Wilkinson et al., Reference Wilkinson, Randhawa and Brown2016; Wilkinson, Randhawa, et al., Reference Wilkinson, Randhawa and Brown2017). HPs with ethnicities other than South Asian ethnic backgrounds found it challenging to build emotional rapport with South Asian migrants due to a lack of knowledge about the culture (Owens and Randhawa, Reference Owens and Randhawa2004).
Although several studies were concerned with providing culturally competent PC toward South Asian migrant families, consensus was missing on how the aim would be achieved. Suggestions included: training of interpreters and advocacy workers in PC settings (Randhawa et al., Reference Randhawa, Owens, Fitches and Khan2003; Wilkinson, Waqar, et al., Reference Wilkinson, Waqar and Gill2017), appointing bilingual health workers (Ackroyd, Reference Ackroyd2003; Randhawa and Owens, Reference Randhawa and Owens2004; Wilkinson et al., Reference Wilkinson, Randhawa and Brown2016), cultural mediators (Khosla et al., Reference Khosla, Washington, Shaunfield and Aslakson2017), and liaison officers (Randhawa et al., Reference Randhawa, Owens, Fitches and Khan2003). Among interpreters, concern was raised about their knowledge of the culture of the ethic group along with language proficiency (Khosla et al., Reference Khosla, Washington, Shaunfield and Aslakson2017).
Discussion
This review has identified three themes from 30 articles globally concerning PC of South Asian migrants. The themes that emerged from the analysis of the articles were: 1) the PC practice within the family, 2) trust as a precondition for PC, and 3) importance of knowledge and cultural competency, each with two sub-themes. Several studies in this review discussed how the challenges of using professional care in the palliative stage was complex and not only connected to culture. Studies also mentioned that lack of competencies in local language resulted in poor communication, and consequently, difficulties in imparting proper information during the palliative stage. Most frequently mentioned barriers to accessing PC was lack of awareness and poor communication between HPs and migrant families. Communication was often hampered, particularly due to language barriers, differences in cultural norms, and the dominant role of relatives. The protective role of relatives and other barriers, e.g. language, was also mentioned in a review conducted among all ethnic groups living in the UK (Evans, Menaca, Andrew, et al., Reference Evans, Menaca and Andrew2012). Patients with life-threatening diseases were rarely informed about their diagnosis, while HPs were willing to open up a discussion about the diagnosis and PC services. Relatives often prevented the open discussion on life-threatening disease to protect the patient until death, although patients wished to know the truth. This is a general challenge faced by the HPs working in countries without appropriate codes and legislation concerning the patients' rights to informed consent (Khalil, Reference Khalil2013). Consequently, a lack of open discussion on diagnosis resulted in poor knowledge and awareness about available PC services.
Themes that emerged throughout this review were the importance of family relationships, role of relatives as resources, and/or vice versa. Studies included in this review mentioned that the care burden was often too high, especially for female caregivers (Somerville, Reference Somerville2001; Venkatasalu, Reference Venkatasalu2017). Jobs outside of the home, household tasks, providing care for young and older relatives at home burdens the female relatives (Kristiansen et al., Reference Kristiansen, Irshad, Worth, Bhopal, Lawton and Sheikh2014; Shanmugasundaram, Reference Shanmugasundaram2015; Somerville, Reference Somerville2001). This scenario is in line with the results of a review conducted among Turkish and Moroccan incurably ill migrant families living in the Netherlands (de Graaff et al., Reference De Graaff, Mistiaen, Devillé and Francke2012). Most of the Turkish and Moroccan migrants preferred to be cared for and die at home, even when home care became a severe burden for the female caregivers (de Graaff et al., Reference De Graaff, Mistiaen, Devillé and Francke2012). The reasons for choosing home care over hospital were considerations including the culturally inappropriate PC services delivered at health facilities, financial constraints, and preference for family care (de Graaff et al., Reference De Graaff, Mistiaen, Devillé and Francke2012). Despite the preference for home care over hospital, higher numbers of hospital deaths occur among South Asian migrants compared to the general population. A cohort study among cancer patients revealed that deaths in hospital were more likely to happen among South Asian migrants compared to their White counterparts living in the UK (Coupland et al., Reference Coupland, Madden, Jack, Moller and Davies2011).
Several studies in this review addressed the central role of the patient in the collective family, where he/she was not ready to make any medical decision that just affected him/her (Akter et al., Reference Akter, Dawson and Sibbritt2017; Chattoo and Ahmad, Reference Chattoo and Ahmad2008; Khosla et al., Reference Khosla, Washington and Regunath2016; Sharma et al., Reference Sharma, Khosla, Tulsky and Carrese2012; Somerville, Reference Somerville2001; Venkatasalu et al., Reference Venkatasalu, Arthur and Seymour2013; Wilkinson, Waqar, et al., Reference Wilkinson, Waqar and Gill2017). Every patient and older individual was considering the burden/wellbeing of other relatives before making any PC decision. Often, the family of the patient in this minority ethnic group was not only referring to the immediate family but to an extended family as well, and often to the community at a large. Thus, PC practice was influenced by the judgement of the community. In general, it was difficult to separate the patients’ individual wishes from his/her family. A study conducted among non-western migrants in Denmark also documented the collectivist idea in the family, which consequently resulted in stress and illness among family caregivers of the younger generation (Nielsen et al., Reference Nielsen, Minet, Zeraig, Rasmussen and Sodemann2018).
It is worth noting that consensus was missing regarding the definition of cultural competency, although several studies in this review mentioned the importance of cultural knowledge/training among HPs (Khosla et al., Reference Khosla, Washington, Shaunfield and Aslakson2017; Owens and Randhawa, Reference Owens and Randhawa2004; Randhawa and Owens, Reference Randhawa and Owens2004; Wilkinson et al., Reference Wilkinson, Randhawa and Brown2016; Worth et al., Reference Worth, Irshad and Bhopal2009). Two systematic reviews on PC of minority ethnic groups in the UK confirm the variety of different terms used to describe cultural competency and a lack of clarity in the usage of cultural competency approaches (Evans, Menaca, Andrew, et al., Reference Evans, Menaca and Andrew2012; Evans, Menaca, Koffman, et al., Reference Evans, Menaca and Koffman2012). Certainly, it is challenging for the HPs to provide culturally competent PC services for a diverse population. As mentioned earlier in this review, South Asian migrants are diverse in their cultural and religious practices, so the HPs would have to keep this in mind while delivering care toward this group. Therefore, it is suggested not to generalize the care toward migrants as a whole (Calanzani et al., Reference Calanzani, Koffman and Higginson2013). A study conducted among older migrants in Denmark suggested that it is also important for the HPs to consider the issue of the individual's life history to provide optimal support (Nielsen et al., Reference Nielsen, Minet, Zeraiq, Rasmussen and Sodemann2017).
Limitations and strengths
The articles in this review were mainly about migrants from India, Pakistan, and Bangladesh, and to a lesser extent, Sri Lanka. Studies concerning migrants from other nationalities in South Asia were not found in this review. This is due to the history of early migration from the aforementioned nationalities. Though a large number of Nepalese and Bhutanese are migrating to western countries in recent years, the age group of the migrants has yet to reach the age that requires PC services (SAALT, 2012). Finally, combining qualitative, quantitative, and mixed method studies made it difficult to synthesize the data.
Despite these limitations, the findings of this review suggest that involvement of relatives in PC decision making would improve communication and build trustworthy relationships with HPs. Considering the burden experienced by migrant families, it would be worth providing supportive interventions for migrant families both in hospital and at home. The intervention should be adjusted according to the needs of the migrant families and their existing healthcare system. This review also reveals suggestions for future research. Studies included in this review discussed the various challenges faced by migrant families and their HPs. The mentioned challenges in this review can be used to assist researchers when planning an intervention toward migrant families. Therefore, further research is required to explore how to support migrant families with interventions at the PC stage.
Conclusion
This review is the first to systematically identify studies and summarize the experiences and perspectives of PC among older South Asian migrants, relatives, and HPs from all over the world. The limited access to PC services among this patient group seems to be related to the dominant role of family caregiving, the lack of communication with professionals, and poor knowledge among migrant families about PC services. However, there is no universal guide to follow, so the policies and practices of HPs need to be particularly sensitive while providing PC services to migrant families. Considering the multi-ethnic nature of the world today, culturally competent PC may be applicable to other migrant populations beyond South Asians migrants.
