Use of Theoretical Frameworks in the Development and Testing of Palliative Care Interventions

Per-Patient Illness Trajectory Analyses

Background: Summary statistics often hide individual patients' suffering, thereby impeding quality improvement efforts. Objectives: We aimed to show the experience of a population with health care toward the end of life while preserving the experience of the individual. Design: We developed a data display method called per-patient illness trajectory analysis. We tested it using a demonstration cohort of 192 patients with cancer referred to a regional Swedish specialized home-based palliative care practice. Chart review provided detailed information about illness trajectory events with a focus on unplanned hospitalization. Results: We created per-patient timelines spanning from cancer diagnosis until death and using a logarithmic scale: Compared with a conventional, linear timescale, this scale expands the time resolution toward the end of life. The method fosters the assessment of unmet palliative care need and care quality for individuals, small high-need groups, and populations. Conclusion: In populations of up to 200 people, per-patient illness trajectory analysis is feasible and promising. Using random sampling, it could be extended to larger populations.

Palliative Care and Advance Care Planning Intervention Fidelity Monitoring: Methods and Lessons Learned From PCORI-Funded Large-Scale, Pragmatic Clinical Trials

Over the past decade, the Patient-Centered Outcomes Research Institute (PCORI) funded multiple large-scale, comparative effectiveness clinical trials evaluating palliative care and advance care planning interventions. These are complex multicomponent interventions that need robust but flexible fidelity monitoring. Fidelity is necessary to maintain both internal and external validity within palliative care intervention research and to ultimately evaluate the real-world impact of high-quality interventions. Different trials not only took varying approaches to fidelity monitoring but also uncovered both unique and common challenges and facilitators. This article summarizes 8 of these trials and highlights approaches, adaptations, barriers, and facilitators for intervention fidelity monitoring. Identifying and delivering core elements while simultaneously allowing adaptations of noncore elements is a vital part of fidelity monitoring. Dissemination of such experiences can inform both future palliative care research as well as ongoing implementation of palliative care and advance care planning interventions across diverse clinical practices. Adoption of rigorous intervention fidelity methods is critical to advancing the science and reproducibility of palliative care interventions.

Advancing Methodological Rigor for Psychosocial Aspects of Neuropalliative Care Interventions

Background: Neurological disorders (NDs) have unique biopsychosocial-spiritual features that impact patients and their families. As a result, the subspeciality of neuropalliative care (NPC) emerged within the past decade and has grown exponentially in research and practice. Given the cognitive, emotional, and behavioral changes associated with NDs, psychosocial components (eg, coping skills) of NPC interventions are essential for improving the quality of life for patients and families. However, psychosocial components of NPC interventions warrant more rigorous testing to improve their evidence base and their likelihood of implementation and dissemination. Aim: In this commentary, we provide methodological recommendations with the goal of improving scientific knowledge and rigor for psychosocial components of multicomponent NPC interventions in clinical trials. Results: We emphasize the need for transparent reporting of psychosocial intervention components; using established models of intervention development to guide the development and testing of multicomponent NPC interventions; identifying mechanisms of action for psychosocial outcomes; and choosing psychometrically sound measures for mechanisms and outcomes. Conclusions: Given the importance of psychosocial care to the holistic NPC model, rigorous testing of psychosocial components of NPC interventions is a high priority for clinical investigators to advance the evidence base and practice of NPC.

Cancer-Related Symptom Frameworks Using a Biopsychosocial-Spiritual Perspective: A Scoping Review

BACKGROUND

Research to understand and manage cancer-related symptoms continues to advance, yet work that more fully adopts a biopsychosocial-spiritual view of symptoms is needed.

OBJECTIVE

The purpose of this article is to review existing frameworks that have the potential to guide research on cancer-related symptoms, to explore the characteristics of each framework, and to appraise each using a biopsychosocial-spiritual lens.

METHODS

A scoping review was conducted to identify available frameworks that could be applied to guide cancer-related symptom research and to assess their characteristics. Research questions and criteria were formulated at the outset, followed by identifying relevant publications detailing novel frameworks, charting data, and collating results. Upon identification of available frameworks, each was appraised for alignment with a standard definition of "biopsychosocial-spiritual."

RESULTS

Eleven frameworks were identified to guide cancer-related symptom research. All were developed in the United States, led by nurse scientists, including symptom experiences as well as their antecedents and outcomes, and could be applied to one or more concurrent cancer-related symptoms. While all 11 frameworks included biopsychosocial dimensions, only 4 included spirituality.

CONCLUSIONS

Four biopsychosocial-spiritual frameworks offer unique insight to support advancement of cancer-related symptom research and practice from a holistic perspective. This foundational work could lead to development and validation of new frameworks and modification of existing frameworks to more closely align with a biopsychosocial-spiritual view of cancer-related symptoms. This review offers a starting point to carefully and explicitly adopt frameworks in research and practice with increased emphasis on considering spiritual dimensions of symptoms.
