A digital biomarker dataset from hematopoietic cell transplant caregivers and patients

This study presents a comprehensive dataset capturing physiological measurements, psychological assessments, and clinical outcomes from 166 hematopoietic cell transplant (HCT) caregiver-patient dyads over 120 days post-transplant. Data were collected using wearable devices (Fitbit® Charge 3), daily mood reports through a custom mobile application (Roadmap), standardized health measures (PROMIS®), and clinical records from electronic health systems. The dataset includes minute-level heart rate measurements, daily sleep patterns, step counts, self-reported mood scores, PROMIS® health questionnaires at three timepoints (baseline, day 30, and day 120 post-HCT), and clinical events including complications and readmissions. Physiological data were collected from both caregivers and patients, providing a unique paired perspective on the transplant recovery process. The dataset offers researchers an unprecedented view into the daily fluctuations and interdependencies of caregiver and patient well-being throughout the critical post-transplant period. This comprehensive resource enables investigation of relationships between physiological markers, psychological states, and clinical outcomes in the context of HCT.
