Abstract
Background:
Mobile health (mHealth) is a promising tool for improving health outcomes. However, the benefits of using mHealth in palliative care are under studied.
Objective:
As a first step to designing meaningful palliative care-specific mobile applications, this research explored provider perspectives regarding the utility of mHealth in palliative care.
Design:
A qualitative phenomenological study with semistructured interviews.
Setting/Subjects:
Providers from multiple disciplines working in palliative care settings at an academic medical center.
Results:
Thematic analysis resulted in five provider recommendations regarding the utility and design of palliative care-specific mHealth, including (i) thoughtfulness to language, context, and delivery when assessing palliative care needs; (ii) include tools for prognosis and advance care planning; (iii) tailor health and quality-of-life goals; (iv) emphasize supports for family and caregivers; and (v) consider technology abilities of older adults.
Conclusions:
Palliative care providers are enthusiastic about the use of mHealth to improve care coordination, facilitate communication, enhance symptom monitoring, and improve patient–family support. However, providers have reservations about mobile functionality and depersonalized assessment and care. Providers stress the utility of mHealth to facilitate palliative care rather than replace important multidisciplinary services.
Background
Mobile health (mHealth), the use of mobile devices to facilitate health services or public health, 1 is growing in popularity in health systems and among providers and patients. 2 One specific type of mHealth is the use of native and hybrid mobile applications (apps), which are software programs downloaded from an app store (iOS App Store, Google Play, and so on) directly onto a mobile device, such as a smart phone or tablet, and function with and without access to the internet. Currently, there are over 318,000 commercially available hybrid and native health-related mobile apps. 3 Such apps are used across a variety of health concerns and needs including chronic disease management, 4 physical activity, healthy eating promotion, 5 smoking cessation, 6 and clinical communication. 7
Palliative care-specific mobile apps, which are relatively new to the field, 8 have targeted supports for cancer patients, 9 prompts for provider-based palliative care consultation, and resource sharing.10–12 However, there are few palliative care apps that target both the patient and family caregivers.13,14 Often, palliative care patients are excluded from disease-specific mHealth trials due to their advanced illness.15,16 While there are a number of positive developments in mHealth that overlap with palliative care, 17 there remains opportunity to facilitate the development of apps to be deployed by palliative care teams that impact the bio-psychosocio-spiritual domains of palliative care and are inclusive of both patient and family. 18
As a first step to designing meaningful palliative care-specific mobile applications, this research explored provider perspectives regarding the utility of mHealth in palliative care. This qualitative study explores provider suggestions and considerations when designing mobile apps for seriously ill populations. The objective of this study is to identify initial recommendations for tools, resources, and functionality necessary to create useful palliative care mobile apps for patients and families.
Methods
Adhering to the Consolidated Criteria for Reporting Qualitative Research, 19 this exploratory qualitative study used semistructured interviews to investigate mHealth for palliative care. A phenomenological methodology20,21 was used to describe provider experiences and considerations to inform future mobile app design for palliative care patients and their family caregivers. The research team considered their epistemological 22 position and bracketed 23 biases to remain reflexive 24 throughout the study. All study procedures were approved by the Colorado Multiple Institutional Review Board.
Sample
Participants were recruited using purposeful sampling 25 from an academic medical center. Initially, the research team targeted 10 providers from a variety of disciplines working with seriously ill patients to ensure interdisciplinary feedback and expertise with seriously ill populations. Snowball sampling methods were then used, asking interview participants to suggest other possible participants, to identify relevant providers who could speak to palliative care mHealth approaches. The research team contacted all potential participants via email to inform them of the study and invite them for an interview. Responses to the recruitment email were considered informed consent, and research team email replies included information about scheduling an interview. Of the 25 providers contacted for an interview, 22 agreed to participate, and 20 interviews were completed. Of those who did not participate, one was on medical leave, two did not respond to the recruitment email, and two initially agreed to participate, but were too busy to complete the interview.
Data collection
During September 2018–February 2019, the research team conducted 20 provider interviews. The one-on-one interviews were conducted by postgraduate-trained researchers with previous qualitative experience (J.D.P. and K.F.). The interviews were held at a private location convenient to the provider, for example, a hospital meeting room or nearby offices. Interviews were ∼30 to 60-minutes in duration and audio recorded.
The research team used a semistructured interview guide to focus the interview. First, providers were asked to give general information regarding their discipline, training, and current clinical work with palliative care or seriously ill patients. Using wireframes, a set of images presented in PowerPoint that displays functional and design elements of the mobile app, participants were asked about their opinions regarding possible app functionality and suggestions for new functions. Eighteen questions and 14 PowerPoint slides with wireframe images probed providers regarding biopsychosocial and spiritual assessment issues, in-app features, potential resources, and related importance to clinical care. Examples of potential log-in, assessment, and resource screens are seen in Figure 1. The interviewer displayed an example wireframe screen and asked a specific question such as: “do you think this would be a helpful assessment question to ask via an app? If so, do you like the way it is displayed? How would you improve the display?” Both the question guide and wireframes were modified during the data collection period iterating participant feedback. Participants were asked to brainstorm about app features that would be particularly helpful to patients and their family members. At the conclusion of the interview, participants were given a $25 gift card.

Analysis
The principle investigator (PI) (J.D.P.) and coders (K.F. and K.E.) met regularly to review data, validate findings, and compare written notes and memos. These meetings were documented within the project audit trail 26 throughout the study. Interviews were transcribed verbatim and analyzed using an iterative, team-based approach. Using the mixed methods software Dedoose (v8.035), 27 coders collaboratively built consensus to develop a codebook and improve interrater reliability. Interrater reliability was calculated for three randomly selected transcripts (81% agreement, K = 0.725), reflecting adequate consistency in coding across coders. The analysts triangulated 28 codes with resources gathered from interviews, including health education materials currently distributed to patients and their families, other mobile application resources, and website suggestions. The research team clustered the themes into categories with significant statements to describe the core essence among responses until thematic saturation 29 was reached. Illustrative quotes were coded as exemplars for each theme. As a method of member checking, 28 the principal investigator met with palliative care and health technology experts to present the specific resulting themes and confirm the credibility of preliminary findings.
Results
Participants
As seen in Table 1, the sample included a diverse set of providers, including physicians, nurses, spiritual providers, social workers, and therapists. Most providers were palliative care specialists, female, and white. Provider experience with seriously ill patients ranged from 2 years to 17 years (9.78 ± 3.75 years).
Provider Characteristics
Recommendations for designing palliative care mHealth
Thematic analysis resulted in five primary provider-based recommendations for designing mHealth. These themes are summarized in Table 2 and include thoughtfulness to language, context, and delivery when assessing palliative care needs; include tools for prognosis and advance care planning; tailor health and quality-of-life (QOL) goals; emphasize supports for the family and caregivers; and consider technology abilities of older adults.
Summary of Themes with Supporting Quotes
Thoughtfulness to language, context, and delivery when assessing palliative care needs
While validated tools and assessments were described as critical in clinical practice, the validated assessment questions provided as a wireframe within an app raised concern with providers. The example assessments displayed included items for physiologic symptoms, spirituality, 30 social support, 31 social concerns, 32 and engagement with advance care planning. 33 Many providers described the questions as awkward and out of context. When not embedded within a clinical encounter, such as an office visit, the providers felt the validated assessments were inappropriate. Similarly, many providers reported the social-spiritual assessment questions are sensitive in nature, and they anticipated response hesitancy.
Many providers described the language used in the validated questions unfitting for a mobile application. Upon reviewing the wireframes, providers felt the wording in the assessments were superfluous, too high level, and nonconversational. Among these considerations, suggestions to improve language, literacy, and wording remained a key consideration when assessing both clinical and psychosocial aspects of the app. There was a strong consensus among providers to dismiss the validated wording when capturing this information. Many providers recommended alternative forms of assessment beyond a standard structured in-app survey. Many providers suggested various methods to improve the modality of validated assessments. Methods of delivery varied across all providers, some suggested interactive text messages, others considered a “chatbot” style of question and answer, and a few providers mentioned these assessments should be initiated by app and then referred to an in-person provider.
A few providers highlighted concerns regarding the overall purpose of assessment question and the data they would be collecting. Many providers described that gathering both clinical and psychosocial information is only appropriate if the device can intervene or offer support based on assessment questions.
Include tools for prognosis and advanced care planning
Many providers highlighted the criticality of expectation management around prognosis and advance care planning. This included the patient's perception of where they are on the chronic illness trajectory. In terms of an app supporting advance care planning and preparing for end of life, providers, particularly nonphysician and advance practice nurse providers, acknowledged the importance of involving family caregivers. Ideas for delivering information related to symptom tracking and illness status to providers and family caregivers most often included graphs focusing patient responses over time.
Tailor health and QOL goals
Providers stressed the importance of offering tailored goal setting and goal-monitoring around disease management and QOL. Goal setting focused on (i) tailoring healthy behavior goals, including increased walking or diet improvements and (ii) tailoring goals focused on QOL, including spending more time with family and friends or addressing spiritual needs. When asked about the utility of biopsychosocial assessment to monitor tailored goals via an app, providers acknowledged the importance of obtaining a more holistic sense of how the patient is doing, particularly in palliative care. Several providers also mentioned the utility of an app for reminding patients of their health and QOL goals and suggesting resources available to them. However, providers raised concerns about the ability of an mHealth algorithm to provide meaningful support for sensitive assessments.
Highlight supports for the family and caregivers
Providers consistently acknowledged that when dealing with chronic illness, caregiver burden is a challenge and discussed the importance of a team-oriented, community approach in chronic illness management and palliative care. Common themes included patient self-management, engagement in care, and relieving caregiver burden. Several providers offered tailored, app-generated suggestions for both the patient and caregivers of how to support each other would be valuable. Many providers told personal stories around the difficulty of communication between patients and family members. When probed, providers expressed enthusiasm with the ability to engage caregivers and care partners using an app. Several providers discussed the utility of an app to promote productive communication regarding care, thus helping family members feel updated about their loved one's condition.
Consider technology abilities of older adults
Most providers expressed hesitation about an older population's ability to access and engage with technology, and several providers spoke about their nontechnically savvy patients. However, with considerations of heuristics and delivery catered to the varying needs of an aging population, many providers agreed that an app to support palliative care would be useful. Suggestions included considerations of reading, typing, and hearing and creating modifications such as speak-to-text and interoperability with hearing aid capabilities. With these considerations in mind, providers expressed value in engaging the social convoy, with greater technical abilities, to improve accessibility and utility of a palliative care mobile app.
Discussion
This study reports provider perspectives and recommendations to facilitate the design of meaningful palliative care-specific mHealth. Our results indicate providers are enthusiastic about the potential of mHealth in palliative care and also identify possible barriers and concerns.
Recommendations for palliative care mHealth
Providers have specific suggestions for how to integrate more mHealth strategies into palliative care. These recommendations provide initial insight into potential next steps for palliative care mHealth.
Use mHealth approaches to facilitate social support and advance care planning
Providers emphasized the need to include tools and supports for caregivers and family members. Previous work indicates that informal caregivers in palliative care settings are receptive to using mHealth. 34 This offers a rationale for better integration of family, caregivers, and social networks into mHealth program development for palliative care. Health-related mobile applications typically target one, individual user rather than a network of users to maximize benefit. 35 Only a few elements of caregiver–family support functions exist via currently available mobile applications. 36 Research is needed to determine best practices for designing mHealth for simultaneous, age-diverse users of patients, caregivers, family, and social networks.
Providers highlighted the utility of mHealth for building on palliative care practices, particularly for prognostication and advance care planning, in a new and shared way. There are initiatives to use health technologies, particularly patient portals, apps, and websites, for advance care planning,37–39 but these mechanisms have yet to implement mobile functionality to target patients and their social network. People are using mobile apps, such as Snapchat and Instagram, to express emotions, events, and life events with their family, friends, and social media network. 40 By incorporating these types of communication functions, palliative care mHealth may provide a unique platform for facilitating difficult conversations related to disease trajectory, goals of care, and advance directive completion. Researchers previously highlighted social media implications for end-of-life communication, 41 but few empirical studies have capitalized on using social media functions 42 to improve health or focus on important palliative care outcomes and services. 43
Use mHealth approaches to facilitate regular assessments
One of the main benefits of mHealth for palliative care identified by providers was the ability to conduct ongoing, holistic assessments. mHealth solutions are commonly used to monitor health behaviors (physical activity and eating), 44 patient reported outcomes (symptom burden, functional impact, and QOL), and sensor-captured health indicators (wireless scale for weight, blood pressure cuff for hypertension). 45 However, current mHealth solutions rarely integrate various types of measurements for holistic biopsychosocial and spiritual assessment nor are these solutions offered in a palliative care population. Also, when collecting this magnitude of assessment data, that is, “big data,” it is important to consider who these data are for and the best use practices. Further research is needed to investigate the maximum value of mHealth patient reported data to determine if data are better-used by providers to improve care or by patients and families to improve heath engagement.46,47
Special considerations
Although there is enthusiasm for mHealth in palliative care, the study providers offer important considerations. Providers also provide specific recommendations to address caution regarding the use of mHealth among patients with serious illness and their families.
Take care to facilitate sensitive communication appropriately with mHealth tools
Providers noted concerns regarding the dehumanization of people's disease experience by using mHealth. This speaks to the ongoing discussion related to potentially negative impacts of health technology in medical care48,49 on provider–patient relationships, personalization, and work flows. Based on our results, palliative care-specific mHealth should be considered a facilitator of supports rather than a replacement of important multidisciplinary services.
These findings also illustrate a challenge of integrating assessment tools that have been validated in clinical contexts in new mHealth modalities. The provider suggestions for de-emphasizing language and specific wording from validated tools acknowledge how communication via mHealth media follows a different set of expectations and cultural norms. Although providers may need validated assessments for research or medical record documentation, using exact items or scales may not be the best format for a mobile application. Despite limited evidence in this area, researchers recommend using the Brief Pain Inventory to measure cancer-specific pain via mHealth. 50 More research is needed to assess the alternative form reliability and responsiveness of using validated palliative care assessments via mHealth platforms.
As providers note, designers must be thoughtful of the context and delivery of sensitive health information in the setting of palliative care. The use of technology in delivering difficult news or end-of-life information can be perceived negatively by patients and their family. For example, in a recent qualitative study, patients, family members, and oncologists indicated that discussing laboratories, scans, and diagnosis via a patient portal can be challenging due to the sensitive nature of the information. 51
Be certain to consider user experience and to address varies experiences with technology in designing approaches
As many palliative care patients and caregivers are older adults, providers recommended careful attention be made to mobile application design for this age group. There are specific guidelines for designing technologies for older adults 52 to improve adoption and usability. User-centered design methods, that is, the inclusion of older adults in the design process, and interdisciplinary collaborative approaches are also recommended for developing mHealth for older users. 53 Despite common misconceptions, older adults and caregivers are interested in using technologies for health information and health care services.54,55
Future research for designing palliative care mobile applications
While this article provides general recommendations, additional research is needed to provide structured guidance to clinicians, researchers, and app designers who are interested in developing apps specifically for palliative care. Unique challenges exist when designing for people with serious illness and the people who help them with their care. Popular mHealth engagement strategies may not be helpful or feasible. Research is needed to explore ways to soften or improve palliative care assessments that have primarily been used in clinical or in-person, specifically investigating which modalities are most accepted and useful for this population, for example, testing patient and caregiver perceptions of chat bot functions, voice interactions, and avatars to cushion sensitive questions regarding serious illness. Further investigation is needed to test digital strategies such as nudges, ecological momentary interventions, and health communication strategies (e.g., text, voice, and pop-up functions) that can promote user engagement with specific palliative care mHealth tools. Such strategies will inform design decisions for goal setting functions such as open-ended versus multiple-choice selection design features. Finally, future work is also needed to design algorithms for assessing and intervening with multiple simultaneous users that include the patient, family, and caregivers. Despite the future research needed, this work offers incremental advancements to improve the technology supporting interventions for patients with serious illness, their family, caregivers, and health care providers.
Limitations
Although this was a comprehensive qualitative investigation, there are several limitations to our study. Data were collected with providers from one academic medical center. Providers in various geographic or more rural areas may offer differing opinions and recommendations. Although we achieved variability in interviewing providers from multiple disciplines, the sample was also limited to white participants resulting in a lack of perspectives from underrepresented clinicians. Furthermore, by using a semistructured interview with wireframes, the interviews may have been too restrictive to fully capture providers' experiences and opinions.
Conclusions
While palliative care providers are enthusiastic about the use of mHealth to improve care coordination, facilitate communication, symptom monitoring, and patient–family support, they have reservations about mobile functionality and depersonalized assessment and care. Providers stress the utility of mHealth to facilitate palliative care for patient, caregivers, and family rather than replace important multidisciplinary services. These recommendations provide direction for the design and development of palliative care mHealth that may lead to improved health outcomes for people with serious illness and their families.
