Acceptability of a Text Message-Based Mobile Health Intervention to Promote Physical Activity in Cardiac Rehabilitation Enrollees: A Qualitative Substudy of Participant Perspectives.

BACKGROUND: Mobile health (mHealth) interventions have the potential to deliver longitudinal support to users outside of episodic clinical encounters. We performed a qualitative substudy to assess the acceptability of a text message-based mHealth intervention designed to increase and sustain physical activity in cardiac rehabilitation enrollees. METHODS AND RESULTS: Semistructured interviews were conducted with intervention arm participants of a randomized controlled trial delivered to low- and moderate-risk cardiac rehabilitation enrollees. Interviews explored participants' interaction with the mobile application, reflections on tailored text messages, integration with cardiac rehabilitation, and opportunities for improvement. Transcripts were thematically analyzed using an iteratively developed codebook. Sample size consisted of 17 participants with mean age of 65.7 (SD 8.2) years; 29% were women, 29% had low functional capacity, and 12% were non-White. Four themes emerged from interviews: engagement, health impact, personalization, and future directions. Participants engaged meaningfully with the mHealth intervention, finding it beneficial in promoting increased physical activity. However, participants desired greater personalization to their individual health goals, fitness levels, and real-time environment. Generally, those with lower functional capacity and less experience with exercise were more likely to view the intervention positively. Finally, participants identified future directions for the intervention including better incorporation of exercise physiologists and social support systems. CONCLUSIONS: Cardiac rehabilitation enrollees viewed a text message-based mHealth intervention favorably, suggesting the potentially high usefulness of mHealth technologies in this population. Addressing participant-identified needs on increased user customization and inclusion of clinical and social support is crucial to enhancing the effectiveness of future mHealth interventions.

Improving the Usability of Written Exposure Therapy for Therapists in the Department of Veterans Affairs Telemental Health: Formative Study Using Qualitative and User-Centered Design Methods.

BACKGROUND: User modifications are common in evidence-based psychosocial interventions (EBPIs) for mental health disorders. Often, EBPIs fit poorly into clinical workflows, require extensive resources, or pose considerable burden to patients and therapists. Implementation science is increasingly researching ways to improve the usability of EBPIs before implementation. A user-centered design can be used to support implementation methods to prioritize user needs and solutions to improve EBPI usability. OBJECTIVE: Trauma-focused EBPIs are a first-line treatment for patients with posttraumatic stress disorder (PTSD) in the Department of Veterans Affairs. Written exposure therapy (WET) is a brief, trauma-focused EBPI wherein patients handwrite about trauma associated with their PTSD. Initially developed for in-person delivery, WET is increasingly being delivered remotely, and outcomes appear to be equivalent to in-person delivery. However, there are logistical issues in delivering WET via video. In this evaluation, we explored usability issues related to WET telehealth delivery via videoconferencing software and designed a solution for therapist-facing challenges to systematize WET telehealth delivery. METHODS: The Discover, Design and Build, and Test framework guided this formative evaluation and served to inform a larger Virtual Care Quality Enhancement Research Initiative. We used qualitative descriptive methods in the Discover phase to understand the experiences and needs of 2 groups of users providing care within the Department of Veterans Affairs: in-person therapists delivering WET via video because of the COVID-19 pandemic and telehealth therapists who regularly deliver PTSD therapies. We then used user-centered design methods in the Design and Build phase to brainstorm, develop, and iteratively refine potential workflows to address identified usability issues. All procedures were conducted remotely. RESULTS: In the Discover phase, both groups had challenges delivering WET and other PTSD therapies via telehealth because of technology issues with videoconferencing software, environmental distractions, and workflow disruptions. Narrative transfer (ie, patients sending handwritten trauma accounts to therapists) was the first target for design solution development as it was deemed most critical to WET delivery. In the Design and Build phase, we identified design constraints and brainstormed solution ideas. This led to the development of 3 solution workflows that were presented to a subgroup of therapist users through cognitive walkthroughs. Meetings with this subgroup allowed workflow refinement to improve narrative transfers. Finally, to facilitate using these workflows, we developed PDF manuals that are being refined in subsequent phases of the implementation project (not mentioned in this paper). CONCLUSIONS: The Discover, Design and Build, and Test framework can be a useful tool for understanding user needs in complex EBPI interventions and designing solutions to user-identified usability issues. Building on this work, an iterative evaluation of the 3 solution workflows and accompanying manuals with therapists and patients is underway as part of a nationwide WET implementation in telehealth settings.

A Text Messaging Intervention for Priming the Affective Rewards of Exercise in Adults: Protocol for a Microrandomized Trial.

BACKGROUND: Physical activity is a critical target for health interventions, but effective interventions remain elusive. A growing body of work suggests that interventions targeting affective attitudes toward physical activity may be more effective for sustaining activity long term than those that rely on cognitive constructs alone, such as goal setting and self-monitoring. Anticipated affective response in particular is a promising target for intervention. OBJECTIVE: We will evaluate the efficacy of an SMS text messaging intervention that manipulates anticipated affective response to exercise to promote physical activity. We hypothesize that reminding users of a positive postexercise affective state before their planned exercise sessions will increase their calories burned during this exercise session. We will deploy 2 forms of affective SMS text messages to explore the design space: low-reflection messages written by participants for themselves and high-reflection prompts that require users to reflect and respond. We will also explore the effect of the intervention on affective attitudes toward exercise. METHODS: A total of 120 individuals will be enrolled in a 9-week microrandomized trial testing affective messages that remind users about feeling good after exercise (40% probability), control reminders (30% probability), or no message (30% probability). Two types of affective SMS text messages will be deployed: one requiring a response and the other in a read-only format. Participants will write the read-only messages themselves to ensure that the messages accurately reflect the participants' anticipated postexercise affective state. Affective attitudes toward exercise and intrinsic motivation for exercise will be measured at the beginning and end of the study. The weighted and centered least squares method will be used to analyze the effect of delivering the intervention versus not on calories burned over 4 hours around the time of the planned activity, measured by the Apple Watch. Secondary analyses will include the effect of the intervention on step count and active minutes, as well as an investigation of the effects of the intervention on affective attitudes toward exercise and intrinsic motivation for exercise. Participants will be interviewed to gain qualitative insights into intervention impact and acceptability. RESULTS: Enrollment began in May 2023, with 57 participants enrolled at the end of July 2023. We anticipate enrolling 120 participants. CONCLUSIONS: This study will provide early evidence about the effect of a repeated manipulation of anticipated affective response to exercise. The use of 2 different types of messages will yield insight into optimal design strategies for improving affective attitudes toward exercise.

Different roles with different goals: Designing to support shared situational awareness between patients and clinicians in the hospital.

OBJECTIVE: Team situational awareness helps to ensure high-quality care and prevent errors in the complex hospital environment. Although extensive work has examined factors that contribute to breakdowns in situational awareness among clinicians, patients' and caregivers' roles have been neglected. To address this gap, we studied team-based situational awareness from the perspective of patients and their caregivers. MATERIALS AND METHODS: We utilized a mixed-methods approach, including card sorting and semi-structured interviews with hospitalized patients and their caregivers at a pediatric hospital and an adult hospital. We analyzed the results utilizing the situational awareness (SA) theoretical framework, which identifies 3 distinct stages: (1) perception of a signal, (2) comprehension of what the signal means, and (3) projection of what will happen as a result of the signal. RESULTS: A total of 28 patients and 19 caregivers across the 2 sites participated in the study. Our analysis uncovered how team SA helps patients and caregivers ensure that their values are heard, their autonomy is supported, and their clinical outcomes are the best possible. In addition, our participants described both barriers-such as challenges with communication-and enablers to facilitating shared SA in the hospital. DISCUSSION: Patients and caregivers possess critical knowledge, expertise, and values required to ensure successful and accurate team SA. Therefore, hospitals need to incorporate tools that facilitate patients and caregivers as key team members for effective SA. CONCLUSIONS: Elevating patients and caregivers from passive recipients to equal contributors and members of the healthcare team will improve SA and ensure the best possible outcomes.

"Eavesdropping": An Information Source for Inpatients.

Healthcare providers in the hospital setting must discuss patient information to ensure continuity of care and patient safety. This study explores how patients perceive the information they hear discussed between healthcare providers and how the concept of "eavesdropping" can be addressed by healthcare providers and in the field of medical informatics. Using an inductive analysis of interviews with 14 adult inpatients, research findings indicate that patients value receiving information in the hospital setting, including information received through eavesdropping. Patient eavesdropping opportunities include "eavesdropping by design" events, such as during bedside shift changes and handoffs, as well as unintended "unintended eavesdropping" events, such as listening to healthcare provider conversations outside of the patient's room. Healthcare providers and medical informaticists have opportunities to address eavesdropping in the inpatient setting. Informatics systems that address "eavesdropping by design" and "unintended eavesdropping opportunities" can improve patient-provider communication and satisfy patient preferences for receiving medical information.

Use and impact of an online community for hospital patients.

OBJECTIVE: Although patient-peer support technologies have demonstrated effectiveness in a variety of health contexts-including diabetes, weight loss, and cancer-less is known about how hospitalized patients can benefit from this support. We investigated the nature of peer support in the hospital and the impact this support had on patients' hospital stays. MATERIALS AND METHODS: We created a technology, resembling an online health community, in which patients could exchange advice about their hospitalization. We deployed it at 1 pediatric hospital and 1 adult hospital. With 30 participants, we conducted bedside interviews, observed how they used the technology during their hospitalization, and completed follow-up phone interviews. RESULTS: Participants shared advice about several topics, including adjusting to the hospital and building relationships with providers. Contrary to concerns that such a system would primarily serve as a place for patients to "complain," sentiment analysis showed that 23 of 36 (64%) of the shared advice reflected positive sentiment. Patients also reported positive impacts to their quality, safety, and hospital experience due to the inpatient peer support community. DISCUSSION: Participants benefited from peer support that transcended diagnoses and individual health conditions. The shared experience of being in the hospital was sufficient to yield valuable and practical peer support. Participants who did not contribute their own advice still experienced benefits from reading their peers' advice. CONCLUSIONS: Our study demonstrated the positive nature of peer advice exchanged, and the benefits of this advice on patients' hospital stays. Inpatient peer support technologies could be an additional resource for patients to engage in their care.

Designing Inpatient Portals to Support Patient Agency and Dynamic Hospital Experiences.

Inpatient portals could help patients engage in their hospital care, yet several design, usability, and adoption issues prevent this technology from fulfilling its potential. Despite patients having needs that extend beyond the scope of existing inpatient portals, we know less about how to design such portals that support them. To learn about effective designs, we created three mid-fidelity prototypes representing novel approaches for inpatient portal design. Then, we conducted interviews with 21 pediatric and adult inpatients to gather their feedback on these prototypes. Participants shared how the prototypes addressed the following needs: forming active partnerships, navigating relationships and power dynamics with clinicians, understanding complexity of care, contextualizing health information, increasing efficiency of communication, and preventing lost information. We discuss two key implications-supporting patients' agency and dynamic needs throughout their hospital care-for the future of inpatient portal designs.

Informatics opportunities to involve patients in hospital safety: a conceptual model.

OBJECTIVE: Inpatients could play an important role in identifying, preventing, and reporting problems in the quality and safety of their care. To support them effectively in that role, informatics solutions must align with their experiences. Thus, we set out to understand how inpatients experience undesirable events (UEs) and to surface opportunities for those informatics solutions. MATERIALS AND METHODS: We conducted a survey with 242 patients and caregivers during their hospital stay, asking open-ended questions about their experiences with UEs. Based on our qualitative analysis, we developed a conceptual model representing their experiences and identified informatics opportunities to support patients. RESULTS: Our 4-stage conceptual model illustrates inpatient experiences, from when they first encounter UEs, when they could intervene, when harms emerge, what types of harms they experience, and what they do in response to harms. DISCUSSION: Existing informatics solutions address the first stage of inpatients' experiences by increasing their awareness of potential UEs. However, future researchers can explore new opportunities to fill gaps in support that patients experience in subsequent stages, especially at critical decision points such as intervening in UEs and responding to harms that occur. CONCLUSIONS: Our conceptual model reveals the complex inpatient experiences with UEs, and opportunities for new informatics solutions to support them at all stages of their experience. Investigating these new opportunities could promote inpatients' participation and engagement in the quality and safety of their care, help healthcare systems learn from inpatients' experience, and reduce these harmful events.

The Value of Patient-Peer Support in Improving Hospital Safety.

Healthcare systems worldwide have dedicated several years, special attention, and action toward improving safety for their patients. Although many innovative technological solutions have helped providers reduce medical errors, hospitalized patients lack access to these solutions, and face difficulties in having a proactive role in their safety. In this paper, we examine how patient-peer support can be a valuable resource for patients in the context of hospital safety. Through semi-structured interviews with 30 patients and caregivers at a pediatric and an adult hospital, we identify the potential benefits of incorporating patient-peer support into patient-facing technologies. Facilitating such support can provide patients with new avenues for engaging in, and improving, the quality and safety of their hospital care.

Using Priorities of Hospitalized Patients and Their Caregivers to Develop Personas.

Hospitalized patients and their caregivers often access technologies like patient portals to understand what happens during their hospital stay. Although this access can lead to more patient engagement and positive health outcomes, many find that the technology does not support their needs. As a first step toward improving patient-facing technologies we create personas for hospitalized patients and their caregivers by following the Q Methodology, a technique for quantifying subjective opinion. We clustered 28 hospitalized patients' and 19 caregivers' attitudes towards receiving and managing information and working with their care team. We contribute three patient personas: patients who are (1) accommodating information seekers, (2) involved safety guardians, and (3) self-managing participators. We identify three caregiver personas: (1) cooperative information seekers, (2) vocal participators, and (3) hands-off safety guardians. These personas can inform future tools designed to support communication and information management for hospitalized patients and caregivers.

Supporting Collaborative Health Tracking in the Hospital: Patients' Perspectives.

The hospital setting creates a high-stakes environment where patients' lives depend on accurate tracking of health data. Despite recent work emphasizing the importance of patients' engagement in their own health care, less is known about how patients track their health and care in the hospital. Through interviews and design probes, we investigated hospitalized patients' tracking activity and analyzed our results using the stage-based personal informatics model. We used this model to understand how to support the tracking needs of hospitalized patients at each stage. In this paper, we discuss hospitalized patients' needs for collaboratively tracking their health with their care team. We suggest future extensions of the stage-based model to accommodate collaborative tracking situations, such as hospitals, where data is collected, analyzed, and acted on by multiple people. Our findings uncover new directions for HCI research and highlight ways to support patients in tracking their care and improving patient safety.

Exploring the Design of an Inpatient Peer Support Tool: Views of Adult Patients.

Despite wide recognition of the value, expertise, and support that patient-peers provide in a variety of health contexts, mechanisms to design and enable peer support in the inpatient setting have not been sufficiently explored. To better understand the opportunities for an inpatient peer support tool, we surveyed 100 adult patients and caregivers, and conducted follow-up, semi-structured interviews with 15 adult patients. In this paper, we describe five key peer support needs that our adult patient participants expressed: (1) adjusting to the hospital environment, (2) understanding and normalizing medical care, (3) communicating with providers, (4) reporting and preventing medical errors, and (5) empowering peers. In addition, we identify privacy concerns, situational impairments, and communication mode as barriers to, and preferences for, interacting with peers. Based on our findings, we discuss intelligent peer matching and aggregating peer data as design recommendations for future inpatient peer support tools.

Must We Bust the Trust?: Understanding How the Clinician-Patient Relationship Influences Patient Engagement in Safety.

Although patients desire safe care, they are reluctant to perform safety-related behaviors when they worry it could harm the relationships they have with clinicians. This influence of the clinician-patient relationship on patient engagement in safety is poorly understood, and most patient-facing safety interventions ignore its influence, focusing instead on helping patients access information about their care and report errors. We conducted semi-structured interviews with hospitalized patients to uncover their needs for patient-facing information systems that could help them prevent medical errors. We found that the clinician-patient relationship could either encourage or discourage patients and caregivers from engaging in patient safety actions. We describe our findings and discuss the implications for the design of patient-facing interventions to promote patient engagement in safety. Our findings shed light on how patient-facing safety interventions can be designed to effectively engage patients and caregivers.

Opportunities and Design Considerations for Peer Support in a Hospital Setting.

Although research has demonstrated improved outcomes for outpatients who receive peer support-such as through online health communities, support groups, and mentoring systems-hospitalized patients have few mechanisms to receive such valuable support. To explore the opportunities for a hospital-based peer support system, we administered a survey to 146 pediatric patients and caregivers, and conducted semi-structured interviews with twelve patients and three caregivers in a children's hospital. Our analysis revealed that hospitalized individuals need peer support for five key purposes: (1) to ask about medical details-such as procedures, treatments, and medications; (2) to learn about healthcare providers; (3) to report and prevent medical errors; (4) to exchange emotional support; and (5) to manage their time in the hospital. In this paper, we examine these themes and describe potential barriers to using a hospital-based peer support system. We then discuss the unique opportunities and challenges that the hospital environment presents when designing for peer support in this setting.

Toward Usable Evidence: Optimizing Knowledge Accumulation in HCI Research on Health Behavior Change.

Over the last ten years, HCI researchers have introduced a range of novel ways to support health behavior change, from glanceable displays to sophisticated game dynamics. Yet, this research has not had as much impact as its originality warrants. A key reason for this is that common forms of evaluation used in HCI make it difficult to effectively accumulate-and use-knowledge across research projects. This paper proposes a strategy for HCI research on behavior change that retains the field's focus on novel technical contributions while enabling accumulation of evidence that can increase impact of individual research projects both in HCI and the broader behavior-change science. The core of this strategy is an emphasis on the discovery of causal effects of individual components of behavior-change technologies and the precise ways in which those effects vary with individual differences, design choices, and contexts in which those technologies are used.

Closing the Gap: Supporting Patients' Transition to Self-Management after Hospitalization.

Patients going home after a hospitalization face many challenges. This transition period exposes patients to unnecessary risks related to inadequate preparation prior to leaving the hospital, potentially leading to errors and patient harm. Although patients engaging in self-management have better health outcomes and increased self-efficacy, little is known about the processes in place to support and develop these skills for patients leaving the hospital. Through qualitative interviews and observations of 28 patients during and after their hospitalizations, we explore the challenges they face transitioning from hospital care to self-management. We identify three key elements in this process: knowledge, resources, and self-efficacy. We describe how both system and individual factors contribute to breakdowns leading to ineffective patient management. This work expands our understanding of the unique challenges faced by patients during this difficult transition and uncovers important design opportunities for supporting crucial yet unmet patient needs.

Partners in Care: Design Considerations for Caregivers and Patients During a Hospital Stay.

Informal caregivers, such as close friends and family, play an important role in a hospital patient's care. Although CSCW researchers have shown the potential for social computing technologies to help patients and their caregivers manage chronic conditions and support health behavior change, few studies focus on caregivers' role during a multi-day hospital stay. To explore this space, we conducted an interview and observation study of patients and caregivers in the inpatient setting. In this paper, we describe how caregivers and patients coordinate and collaborate to manage patients' care and wellbeing during a hospital stay. We define and describe five roles caregivers adopt: companion, assistant, representative, navigator, and planner, and show how patients and caregivers negotiate these roles and responsibilities throughout a hospital stay. Finally, we identify key design considerations for technology to support patients and caregivers during a hospital stay.

A framework for self-experimentation in personalized health.

OBJECTIVE: To describe an interdisciplinary and methodological framework for applying single case study designs to self-experimentation in personalized health. The authors examine the framework's applicability to various health conditions and present an initial case study with irritable bowel syndrome (IBS). METHODS AND MATERIALS: An in-depth literature review was performed to develop the framework and to identify absolute and desired health condition requirements for the application of this framework. The authors developed mobile application prototypes, storyboards, and process flows of the framework using IBS as the case study. The authors conducted three focus groups and an online survey using a human-centered design approach for assessing the framework's feasibility. RESULTS: All 6 focus group participants had a positive view about our framework and volunteered to participate in future studies. Most stated they would trust the results because it was their own data being analyzed. They were most concerned about confounds, nonmeaningful measures, and erroneous assumptions on the timing of trigger effects. Survey respondents (N = 60) were more likely to be adherent to an 8- vs 12-day study length even if it meant lower confidence results. DISCUSSION: Implementation of the self-experimentation framework in a mobile application appears to be feasible for people with IBS. This framework can likely be applied to other health conditions. Considerations include the learning curve for teaching self-experimentation to non-experts and the challenges involved in operationalizing and customizing study designs. CONCLUSION: Using mobile technology to guide people through self-experimentation to investigate health questions is a feasible and promising approach to advancing personalized health.

"Not Just a Receiver": Understanding Patient Behavior in the Hospital Environment.

Patient engagement leads to better health outcomes and experiences of health care. However, existing patient engagement systems in the hospital environment focus on the passive receipt of information by patients rather than the active contribution of the patient or caregiver as a partner in their care. Through interviews with hospitalized patients and their caregivers, we identify ways that patients and caregivers actively participate in their care. We describe the different roles patients and caregivers assume in interacting with their hospital care team. We then discuss how systems designed to support patient engagement in the hospital setting can promote active participation and help patients achieve better outcomes.
