Needs and Concerns Regarding a Pediatric Palliative Telehealth App for Use in Palliative Home Care for Adults Among Providers in Germany: Embedded Mixed Methods Study.

Background: Specialized outpatient palliative care (SOPC) provides home-based care for terminally ill patients and is associated with improved quality of life and prolonged survival. Due to its decentralized structure and growing demand, SOPC is a key target for digital transformation. Telehealth, mobile health, and AI offer considerable potential benefits but also present challenges, particularly with regard to user acceptance. Although both children and adults receive SOPC under the German statutory health insurance system, services differ in terms of patient characteristics, duration of care, and geographic coverage. Moreover, there is limited knowledge regarding the extent to which digital health applications are transferable across different areas of palliative care. Objective: This study assesses the extent to which needs and concerns regarding digitalization in SOPC for children are transferable to adult SOPC, using the PalliDoc Mobile app as a case example. Methods: Two adult SOPC teams using the PalliDoc Mobile app (a pediatric-origin mobile app) were surveyed between March 2022 and March 2025 using an embedded mixed methods design to assess digitalization needs and concerns. Therefore, a focus group study took place in the respective offices of the included teams. Twenty-five members from both teams, who were recruited via the personal network of the authors, participated, representing urban and rural care areas in Germany. Using an open-ended interview guide, the needs and concerns were first discussed with all participating members of each team. In a second step, the participants were allocated to profession-specific subgroups to further explore and prioritize the identified needs using a quantitative voting format. The focus group discussions were analyzed using qualitative content analysis, while the analysis of the prioritization votes was performed using descriptive statistics. Results: The triangulation of qualitative and quantitative findings revealed a total of 13 needs within the examined care teams for adults, with functions focusing on voice control being the highest priority (n=8 positive votes and no negative votes for voice input; n=6 positive votes and no negative votes for voice output). Additionally, functions relating to digitization and organizational tasks were viewed as predominantly helpful. Unlike in pediatrics, telehealth functions like video contacts, telemetry, and electronic patient-reported outcome measures are neither used here now nor intended to be used in the future. The identified concerns predominantly addressed the potential risk of AI-assisted documentation (n=2 positive votes and n=7 negative votes) altering or distorting health care professionals' perception of information related to patients. Conclusions: Cross-setting telehealth applications may work, but they are no "plug-and-play solution." Needs and concerns in each setting should be addressed to guarantee customized services.
