This feasibility study sought to facilitate daily engagement between Mandarin-speaking patients and RTTs with use of an ITD. Critical to the evaluation was the assessment of clinical application – specifically the extent to which the ITD facilitated information provision and the ability to build rapport. The investigators utilised patient and RTT surveys to elicit perspectives on the suitability and acceptance of ITD use within daily RT service provision, and viability for study expansion.
Information Provision & Building Rapport
This feasibility study demonstrated that a majority of patients and RTTs saw use for the ITD in conveying treatment instructions and information. An inability to communicate critical information between a health provider and a CALD cancer patient may otherwise limit active engagement, decision-making and compliance throughout treatment [10, 14–18]. Supporting literature raises concern for the provision of information where there is an absence of a mutual language [10, 14–16].
In the RT context, treatment instructions may vary from ensuring patient preparedness in advance of attending for treatment (i.e. bladder filling, voiding bowel, pre-medication requirements, etc.) to in-room treatment positioning requirements. Broader RTT information may encompass treatment scheduling, side-effect management and self-care advice [19].
However, a disparity existed when patients and RTTs responded to the role the ITD played in facilitating informal conversation. Patient participants reported the device capable of striking a balance between information provision and building rapport. RTTs however, saw less value in the use of the ITD for engaging in ‘small talk’. Current literature reports a clear desire for CALD cancer patients to build trust and rapport with treating health providers, rather than merely facilitate a transactional engagement [17, 18]. This is best captured by Butow et al (2011), who compare standard service provision to ‘… like being in a bubble, able to see, but unable to communicate with the outside world’ [17]. It is understood that improved engagement will help to address unmet emotional, coping and support needs of CALD cancer patients [10, 16, 18]. Thus, it may be reasonable to associate the perceived value of the ITD in facilitating general conversation as relative to the disparate baseline (common) experience of healthcare by patient and staff participants, respectively.
Suitability & Acceptance of ITD Use
This study revealed a higher rate of reported technical issues experienced by RTTs, as opposed to patients. Given RTTs facilitated the use of the device, these issues may not have been evident to the patient, should the device have been withdrawn from daily use, or rectified prior to clinical use. Signal drop out was commonly reported – addressed in part with a substitution from Wi-Fi to SIM connectivity. However, the nature and design of the bunker environment will continue to be a challenge for communications technology. As the study advanced, the use of SIM-card connectivity increased in an effort to mitigate these issues, rather than relying on the hospital's Wi-Fi.
In light of reported informal use of machine translation technology in the clinical domain, this study sought to determine clinical suitability and acceptance by patients and RTTs alike [10]. Prior research completed by the investigators had demonstrated confidence in the output accuracy for English to Mandarin translations and appropriateness with respect to technology and infection control protocols within the Victorian public RT service [11].
Despite varying perceptions of patients and RTTs on the scope of use and prevalence of technical issues, the use of the ITD within clinical practice was largely considered a positive addition to RT treatment provision.
Study Limitations & Recommendations
In March 2020, the emergence of the COVID-19 pandemic drastically altered the provision of healthcare within Victoria [20–23]. To ensure public safety, restrictions were imposed on visitations, travel, contact time and research activity across Victorian RT services [21, 22]. With concern for the timeliness of a return to usual care provision, the investigators elected to cease recruitment to the study with eighteen patient participants (90% of target).
Considering the current study recruitment, there is merit in expanding this research to draw upon a larger sample size of patients. This would allow for meaningful multi-variate analysis, such as the correlation of demographical features, health/English literacy and frequency of device use to overall patient experience and satisfaction. Study design should seek to consider the impact of the device on patient care, treatment outcomes and service delivery. Furthermore, scaled implementation of the current study design would present opportunity to evaluate and inform the requisite training and educational requirements for broad adoption.
