Providing outpatient cancer care for CALD patients: a qualitative study

Objective There have been few descriptions of how outpatient cancer care is provided to patients from culturally and linguistically diverse (CALD) communities. As populations who experience disparities in cancer care access and outcomes, deeper understanding is needed to help identify those factors which can shape the receipt of multidisciplinary care in ambulatory settings. This paper reports on data collected and analysed as part of a multicentre characterisation of care in Australian public hospital cancer outpatient clinics (OPCs). Results Analysis of data from our ethnographic study of four OPCs identified three themes: “Identifying CALD patient language-related needs”; “Capacity and resources to meet CALD patient needs”, and “Making it work for CALD communities.” The care team comprises not only clinicians but also families and non-clinical staff; OPCs serve as “touchpoints” facilitating access to a range of therapeutic services. The findings highlight the potential challenges oncology professionals negotiate in providing care to CALD communities and the ways in which clinicians adapt their practices, formulate strategies and use available resources to support care delivery.

Introduction
How is multidisciplinary cancer care provided to patients from culturally and linguistically diverse (CALD) communities within ambulatory cancer settings? Multidisciplinary care is considered best practice in cancer care [1][2][3][4]. It seeks to promote equitable, evidence-based care by a multidisciplinary team (MDT) that combines expertise relevant to the disease and to patient needs, and supports patients in decision-making about their care [5,6]. Research indicates that people with cancer may have a variety of needs including medical, informational and supportive care needs [7][8][9]. Hospital outpatient clinics (OPCs), are central sites which can support collaboration between different areas of expertise (such as allied health professionals) to better meet these patient needs.
Multidisciplinary care can be challenging to accomplish, given the complexities of cancer and its management, with multiple transitions between service providers and the burden of illness experienced by patients [10][11][12][13]. For those in CALD communities, a variety of factors can detrimentally impact healthcare access and experience, including: language and communication issues [10,[14][15][16][17][18][19][20]; cultural attitudes and beliefs about illness [17,[21][22][23]; poorer health literacy [21] anticipated or experienced cultural insensitivity, discrimination, lack of cultural competence on the part of providers [17]; and sub-optimal access to, or use of interpreter services [14, 16-19, 21, 23]. In oncology, studies indicate that providers often adopt a variety of strategies to aid communication with CALD patients and their families [15]. However, concerns have been raised about the quality and sufficiency of information provision and support where language barriers exist [15,18,23,24].
A deeper understanding of care provision for CALD communities is needed to identify those factors which may contribute to disparities in cancer outcomes, to inform service improvement [7]. We conducted a multicentre study which characterised the organisation and practice of care in outpatient clinics (OPCs) and identified the barriers to, and facilitators of its provision. This paper reports the CALD-relevant data collected as part of that study [25].

Methods
A multi-site ethnography was conducted in four public hospital cancer OPCs over a 9-month period [26,27]. This ethnographic method was selected to provide an in-depth and sophisticated examination of health care settings [26,27]. Specifically, this approach comprised of: in-situ observations so to generate descriptions of the nuanced day to day reality of care delivery in OPCs; interviews with key professionals in order to provide insights into care processes and learn about barriers and facilitators to this work; and document review to allow consideration of the aforementioned data within the relevant service provision context.

Context of services
Hospitals were located across two government healthcare districts that serve as hubs, drawing together networks of multidisciplinary professionals including doctors, nurses and allied health professionals from all disciplines related to oncology care to facilitate professional collaboration, patient referral and impromptu consultations. An overview of services in these areas is shown in Table 1.
In both districts, well over one third of residents were born overseas, almost half of residents in district 1 and over one third of district 2 residents spoke a language other than English at home and approximately 10% of residents in district 1 and 6% in district 2 reported speaking English 'not well or not at all'; all higher than the reported averages for NSW [28]. Other than English,  languages commonly spoken in these districts were Arabic, Vietnamese, Mandarin, Cantonese and Greek.

Procedure
Recruitment: Professional groups targeted for interviews were recruited using email and on-site information sessions; informed consent was obtained. Permission to observe was granted by authorities responsible for OPCs. Fieldwork: A range of data were collected during in-situ observation (n = 135 h approximately), key informant interviews (n = 13) (please see Additional file 1 for interview guide) and document review (n = 8), as detailed in Table 2.
Data management: Data were managed securely and analysed using an inductive approach, as outlined elsewhere [29][30][31]. From this corpus of data, a sub-set relevant to care for CALD patients was extracted, collated, and a coding framework developed. Face validity of the framework was achieved via review from experienced team members (BNGE, KL and DFP) and data were thematically analysed [31]. Fig. 1.

Theme 1. Identifying CALD patient language-related needs
Oncology staff were keenly aware they were providing care for CALD populations and reflected upon this positively: "I quite like the challenge that comes with working in this district. Different cultures, everyone has a different story to tell. " (Key Informant (KI6)) Staff also reported this could be a "struggle" (KI6). They appreciated that CALD patient needs may be more complex to identify and address, with implications for the coordination of care and engagement with other professionals.
A chief focus in OPCs was the identification of patients for whom language was a barrier. Staff considered patients' English language proficiency and the support available from family and friends when determining needs. It was not always possible to identify these patients in advance: "…frequently someone will just come up and say [something in another language], and the most I can say is 'what language?' They might say 'Vietnamese' and then I'll have to call the interpreter service to get someone on the phone. " (KI8) Where oncology staff were aware of language barriers, this alerted them to the need for written information in the patient's primary language, allowing additional time for consultations and the support of interpreter services: "We need to organise that for them and to have them present to sign the consent form for treatment. If there isn't a physical interpreter present in the consultation, then most likely we might use a telephone interpreter. " (KI4) Identifying and addressing these needs was crucial for establishing shared understandings and facilitating consent-giving processes.

Theme 2. Capacity and resources to meet CALD patient language needs
Generally, in hospitals, professional health care-specific interpreters (HCIs) and multilingual signage were available. Two cancer OPCs offered relevant written multilingual resources and in one OPC, a multilanguage electronic check-in system was available. However, not all resources were easily-accessible for CALD patients, and challenges were reported by staff:

"I do a lot of my consults on the phone. It's [the symptom screening tool tool] really lengthy… to sit there on the phone and [talk with] patients that don't speak English very well. I don't think it is working very well. " (KI7)
Some staff were able to communicate with patients and their families in a range of languages and multilingualism was highly valued. One staff member reflects:

"One of the big challenges for me is not being able to speak Vietnamese or Arabic. " (KI5)
Staff expressed appreciation for the work of HCIs and viewed this service as vital. Nonetheless, difficulties were noted concerning service availability, especially when support was required spontaneously:

"It takes about 20 minutes for them to even answer the phone [referring to the HCI service], and then to get someone who is available … It just happened to me yesterday. [It] ended up being like a three-way call between the patient and the daughter and the interpreters and back and forth between them; … multiple phone calls … for a simple query from the patient; it was a two hour affair … because it was so hard to get them. " (KI1)
Staff noted a preference for in-person interpretation because of the difficulties associated with the telephonemediated service. They described the telephone service as hindering communication with the patient and more "time-consuming. " (KI3). Nic Giolla Easpaig et al. BMC Res Notes (2021) 14:304

Theme 3. Making it work for CALD patients
Oncology staff employed various strategies to help bridge the gap between identified needs and the resources available. As staff depend on the availability of HCIs, they reported rescheduling or staying later to access them. They also prioritised and reorganised workload as proactive strategies to maximise the likelihood of accessing in-person interpretation:

"If there is a known psychosocial issue, […] if we see them in clinic then we've got the interpreter. Where it is an English-speaking person, I know I can call them the next day and speak on the phone. So, I would prioritise the non-English speaking person [for the clinic]. " (KI2)
Staff tailored their approaches based on their assessment of language proficiency. For example, some aspects of care could be discussed over the phone, while other aspects required a HCI-supported discussion at the clinic.
Securing interpreter services was a group-based activity in some OPCs: Staff providing administrative support appeared to be regularly on the phone attempting to secure HCIs. Clinical and non-clinical staff alike were involved in obtaining these services for patients. (Fieldnote p26) The care team expands to encompass professionals with the expertise necessary to meet patient needs and, for CALD patients, our data would suggest that not only HCIs and non-clinical staff but also family and friends could be considered part of this team. All these groups made contributions in the form of advocacy, interpretation/translation, as sources of information about cultural needs and as providers of emotional support.

Discussion
The ethnographic exploration of multidisciplinary care in ambulatory settings enabled the generation of a detailed account of care delivery to CALD patients, informed by direct observations and insights of those on the frontlines of providing this care. Analysis of these data led to the identification of pertinent themes and behavioural examples of prioritization, strategizing, adaption and work reorganization in an attempt to provide the best care possible for CALD patients in day-to-day practice. Within the multidisciplinary care and patient-centred paradigm, patients are considered as partners in decision-making [32]; language and cultural barriers impede patient understanding and consent-giving [33]. Consistent with the literature, ensuring availability of HCIs, allowing additional time and providing translated resources [15][16][17][18]21] were needed to support patient-provider interactions. Based on our observations and discussions, this appears to require additional resourcing to ensure that CALD patients receive the same care quality as the majority population. As such, we support calls to assess the additional cost of care to CALD populations so that they can be factored into budgetary provisions.
Studies have identified strategies used by oncology professionals to facilitate interactions with CALD patients, such as rapport-building and employing non-verbal modes of communication [15,16]. In OPCs, staff anticipate issues and formulate strategies to mitigate the risk of ineffective interaction. Nominated strategies included prioritisation and reorganisation of workload and schedules to facilitate optimal engagement with CALD patients, and collaboration among clinical and non-clinical staff to obtain interpreter services.
The desire expressed for increased in-person interpreter services in the OPC may, if addressed, yield additional benefits. These settings function as hubs for a multidisciplinary range of professionals, including many categories of allied health staff. Concerns have been expressed that CALD patients may not receive sufficient or equitable psychosocial support, hope-giving or information [15,18,23,24]. Shifting practice to ensure in-person, translator-supported OPC attendance could facilitate prompt identification of needs and access to relevant therapeutic services. In light of the large-scale uptake of telemedicine  [34,35], it is important to consider the implications for CALD patients, and to explore the possible role of videoconferencing with an interpreter, or integrated care with a General Practitioner who knows the patient and speaks their language.
Our findings suggest a need to conceptualise the multidisciplinary team in OPCs as a collaboration of clinical and non-clinical staff including HCIs, as well as the families of CALD patients. Emotional, informational and translation support and advocacy may be welcomed given the burden of illness and complexities of cancer care [10][11][12][13]. Clarity is needed about the specific contributions made by team members, as there can be a misunderstanding about the role of HCIs [19] (e.g., to translate vs. providing emotional support). Further, while family and friends can make important contributions to supporting patient care, it is not considered appropriate for them to act as HCIs, to ensure patient autonomy [16,33,36].
Consistent with the literature, capacity to accurately and comprehensively identify patients with linguistic needs within a timeframe sufficient to make appropriate arrangements and ensure the provision of translated resources was identified as helpful [15,16,19]. The findings support the view that oncology staff need interpreter services to be available and flexible, and prefer in-person translation services [15,16]. Also observed were aspects of services which may enhance accessibility (e.g., multilanguage check-in kiosks). These findings highlight not only the potential challenges staff negotiate in OPCs, but the ways in which they adapt their practice, formulate strategies and use available resources to provide care to CALD patients.
There is a need to develop evidence-informed guidelines on how hospitals should optimise care delivery for CALD populations and the associated costs. Adherence with guidelines could be monitored, which could be linked to funding mechanisms, i.e., hospitals adhering to guidelines receive additional funding. Better data collection to routinely identify CALD patients and the expenditures related to their care, compared to a similar level of care provided to non-CALD patients, could be a basis for determining whether activitybased funding formula should include a loading for these patients [37] as occurs for Aboriginal and Torres Strait Islander patients [38]. Observing the additional complications for care-giving in the presence of language-barriers, it is crucial to estimate and provide for the additional resources required to provide equitable care.

Limitations
This study opportunistically captured data about care to CALD patients within the broader study; there is a clear need for ethnographic research explicitly tailored to this population. The perspectives of CALD patients, their families and communities, and of HCIs, are needed to comprehensively study these issues. The study examined care provided to those patients who have been referred and are being treated at cancer centres, while evidence indicates reduced screening rates and delays in presentations for CALD community members [39,40]; an important aspect of inequalities in cancer care not addressed in this paper. Overcoming language barriers was what was observed to dominate practice and is the focus of this paper; it is likely that some of the communication difficulties also reflect cultural differences [19,23], which were not systematically explored.
