What this Trial Is About
Researchers are studying the effects of phlebotomy, a blood removal procedure, on heart rate and other physical functions in adults with polycythemia who need regular phlebotomies. This observational study aims to understand how changes in hemoglobin levels affect patient physiology, quality of life, and activity, helping to guide treatment decisions for anemia, blood donation safety, and polycythemia management. Participants will be monitored continuously using wearable devices starting one week before a phlebotomy and continuing until one week after, across three separate phlebotomy events. The study collects data on heart rate, blood pressure, physical activity, and quality of life through devices like the Withings BPM and Steel HR, and questionnaires such as the EuroQol-5D. During the study, patients will wear monitoring devices and complete daily quality of life questionnaires. Researchers will track heart rate and blood pressure daily for one week before and after each phlebotomy. The main measure is the average heart rate around phlebotomy events. This remote monitoring approach helps assess physical changes and well-being over the course of treatment, with participation lasting through three phlebotomies.
