AbstractIntroduction: Peritoneal carcinomatosis (PC) afflicts women with advanced gynecologic cancers. Patients with PC often require ostomies, gastric tubes, or catheters to palliate symptoms, yet patients and caregivers report feeling unprepared to manage these devices. The purpose of this study was to develop and field test the Building Out Lifelines for Safety, Trust, Empowerment, and Renewal (BOLSTER) intervention to support patients and their caregivers after hospitalization for PC. Materials and Methods: We adapted components of the Standard Nursing Intervention Protocol with stakeholders and topical experts. We developed educational content; built a smartphone application to assess patients' symptoms; and assessed preliminary feasibility and acceptability in two single-arm prepilot studies. Eligible participants were English-speaking adults hospitalized for gynecologic cancer-associated PC and their caregivers. Feasibility criteria were a ≥50% consent-to-approach ratio and ≥80% outcome measure completion. The acceptability criterion was ≥70% of participants recommending BOLSTER. Results: During the first prepilot, BOLSTER was a 10-week intervention. While 7/8 (87.5%) approached patients consented, we experienced high attrition to hospice. Less than half of patients (3/7) and caregivers (3/7) completed outcome measures. For the second prepilot, BOLSTER was a four-week intervention. All (7/7) approached patients consented. Two withdrew before participating in any study activity because they were "too overwhelmed." We excluded data from one caregiver who completed baseline measures with the patient's assistance. All remaining patients (5/5) and caregivers (4/4) completed outcome measures and recommended BOLSTER. Conclusion: BOLSTER is a technology-enhanced, nurse-led intervention that is feasible and acceptable to patients with gynecologic cancer-associated PC and their caregivers.
