Facets of physical function assessed by patient-reported outcome measures in oncology research.

PURPOSE: The U.S. Food & Drug Administration has identified physical functioning (PF) as a core patient-reported outcome (PRO) in cancer clinical trials. The purpose of this study was to identify PF PRO measures (PROMs) in adult cancer populations and classify the PROMs by content covered (facets of PF) in each measure. METHODS: As part of the Patient Reports of Physical Functioning Study (PROPS) research program, we conducted a targeted literature review to identify PROMs that could be used in clinical trials to evaluate PF from the patient perspective. Next, we convened an advisory panel to conduct a modified, reactive, Delphi study to reach consensus on which PF facets are assessed by PROMs identified in the review. The panel engaged in a "card sort" activity to classify PROM items by PF facets. Consensus was reached when 80% of panel members agreed that at least one facet was being measured by each PROM item. RESULTS: The literature review identified 13 PROMs that met inclusion criteria. Eight facets of PF were identified for classification in the Delphi study: ability, completion, difficulty, limitation, quality, frequency, bother, and satisfaction. Through two rounds, the panel documented and classified conceptual approaches for each PRO item presented. The most prevalent PF facets were ability, difficulty, and limitation. CONCLUSION: Classifying PF PROMs by PF facets will promote more consistent communication regarding the aspects of PF represented in each PROM, helping researchers prioritize measures for inclusion in cancer clinical trials.

What facets of physical function are most important to adults diagnosed with cancer?

PURPOSE: Successful patient-focused drug development involves selecting and measuring outcomes in clinical trials that are important to patients. The U.S. Food & Drug Administration's definition of clinical benefit includes how patients feel, function, or survive. Patients are considered the experts in describing how they feel and function. In cancer trials, patient-reported measures of physical function provide insight into how patients function at baseline, benefit from the interventions being studied, and the impact of treatment side effects. We conducted a qualitative study with adults diagnosed with cancer to describe facets of physical function from their perspective and to identify which facets are most important to this patient population. METHODS: Using concept elicitation and cognitive interviewing techniques, we conducted semi-structured interviews with 72 adults ≥ 22 years of age with cancer who received treatment with an anticancer drug or biologic within six months of the interview. We selected participants using purposive sampling with the aim to elicit diverse experiences regarding how they may interpret and respond to questions related to physical function. Participants were presented with patient-reported outcome (PRO) items representative of PRO measures used in cancer and general populations. RESULTS: Five facets of how physical function relates to activities were defined from the patient perspective: ability, difficulty, limitation, satisfaction, and completion. More than half of the participants indicated that ability was the most important facet of physical function. The next most important were satisfaction (18.3%), limitation (14.1%), difficulty (5.6%), and completion (2.8%). CONCLUSION: This study demonstrates that we must be more specific about the facets of physical function that we set out to assess when we use PRO measures to describe the patient experience. These results have implications for the specificity of physical function facets when measured in cancer clinical trials.

Facilitators and barriers to eliciting physical function goals before and after surgery: A qualitative study with clinicians.

OBJECTIVE: Describe clinicians' perspectives of facilitators and barriers to eliciting physical function goals from patients with multiple chronic conditions pre- and post-surgery. METHODS: Semi-structured qualitative interviews were conducted with clinicians, recruited from an academic medical center, who treat adult patients with multiple chronic conditions. Purposive sampling ensured multiple provider types were represented. Interviews were conducted in person or via web conference and were audio recorded. Findings were summarized using descriptive qualitative content analysis. RESULTS: Of the 12 participating clinicians, 92% were female and 83% specialized in geriatrics. Clinicians had a mean of 10.7 (min-max: 1-30) years of experience. Key facilitators to goal-setting conversations were sufficient time, familial support, and patient cognitive ability. Barriers included lack of time, lack of training, patient challenges in choosing realistic and specific actionable goals, emotional barriers, and cognitive challenges. CONCLUSION: Some facilitators and barriers are modifiable, including time, inclusion of family members in the clinical encounter, and clinician training to enable actionable goal setting. These results highlight areas for intervention to facilitate goal elicitation for physical function in clinical care settings. PRACTICE IMPLICATIONS: Clinicians should be aware of the barriers impacting eliciting goals. Healthcare organizations could consider providing effective goal elicitation training and tools to facilitate goal setting conversation.
