The primary goals of this study are to: 1) estimate the prevalence of: a) caregiver identification practices, b) psychosocial and/or needs assessment practices for caregivers, and c) the availability of and funding models for supportive care services for caregivers at community oncology practices (Objective 1), and 2) assess the perspectives of multi-disciplinary oncology health care providers regarding: a) perceived responsibility for, and barriers to, assessing and supporting caregivers, b) the importance of and self-efficacy in communicating with caregivers, and c) preferences regarding systems approaches to assess and meet caregivers' needs (Objective 2). Additionally, we will explore various practice and provider -level factors that are associated with the listed outcomes in objectives 1 and 2 respectively (Objective 3a and 3b). This study is estimated to enroll 138 Supportive Care Leaders (e.g., Director of Psychosocial Oncology, Supportive Care Services, or Cancer Patient Support) and 690 multidisciplinary Oncology Providers including physicians, nurses, and physician assistants/nurse practitioners. Participants will complete a one-time web-based survey (estimated at 15-20 minutes to complete). The supportive care leader survey will capture: (1) practice characteristics including caregiver identification and psychosocial assessment practices and preferences; supportive care resources; practice structure; practice technology resources; and status of the Caregiver Advise Record and Enable (CARE) Act. The oncology provider survey will capture: (1) provider skills in caregiver communication; perceived responsibility, knowledge and skills, and awareness of resources for meeting caregiver needs; barriers to meeting caregiver needs; provider characteristics; and system intervention preferences.

For data capture regarding supportive care leaders (Objective 1 and 3a), this will be a convenience sample of responders from all WF NCORP sites, therefore no randomization or stratification is necessary.

Regarding objectives pertaining to oncology providers (Objective 2 and 3b), participating sites with corresponding supportive care leaders will identify an appropriate supportive care leader to generate 3 lists of providers: 1) physicians, 2) nurses, and 3) physician assistants/nurse practitioners who routinely provide cancer care (Oncology Care Provider Identification Form, Appendix B). Using previous Landscape data regarding oncology physicians, we estimate that 50% of practice groups have 1-9 oncology physicians, 25% have 10-20, and 25% have 20+ physicians. After practices respond with lists of physicians, nurses, and physician assistants/nurse practitioners, we will classify each site as small, medium, and large using the criteria for physicians listed above. Assuming similar distributions as seen in Landscape, we will randomly sample 4, 12, and 20 total providers at small, medium, and large sites respectively. With approximately 50% of practices participating, we plan to target a weighted average of 10 providers per practice with the goal of a weighted average of 5 completed provider surveys (50% response/practice) for a total of 690 providers included in objective 2 (sample size justification follows in section 9.3). In addition, we will stratify and proportionally allocate by provider types identified at each site using self-weighting samples supplied in their lists of providers. Therefore of those randomly sampled, we will target roughly the same proportion of physicians, nurses, and PA/nurse practitioners as identified from their site administrator. Coordinators at each NCORP practice will provide e-mail addresses only for randomly selected providers (selected numbers from a numbered list), based on the size of the center and stratified proportional to provider types.
