However, patients with breast cancer receiving oral cyclin-dependent kinase 4/6 inhibitor therapy still require regular hospital visits to monitor side effects. Telemonitoring has the potential to reduce hospital visits while maintaining quality care.<h4>Objective</h4>This study aims to develop a digital home-based health care center (DHHC) for acquiring electrocardiograms (ECGs), white blood cell (WBC) counts, side effect photo documentation, and patient-reported quality of life (QoL) data.<h4>Methods</h4>The DHHC was set up using an Apple Watch Series 6 (ECG measurements), a HemoCue WBC DIFF Analyzer (WBC couJMIR cancere64083https://www.ebi.ac.uk/biostudies/studies/S-EPMC12064077biostudies-literatureA Digital Home-Based Health Care Center for Remote Monitoring of Side Effects During Breast Cancer Therapy: Prospective, Single-Arm, Monocentric Feasibility Study.PMC12064077Limpert MKreis PHeindl FVolz BMocker ARoth ERuebner MWurmthaler LAFasching PAHuebner HKruckel AKallert MUhrig SHorner MSeitz KErnst MGeck JHack CCBeckmann MWGoossens CfalseA Digital Home-Based Health Care Center for Remote Monitoring of Side Effects During Breast Cancer Therapy: Prospective, Single-Arm, Monocentric Feasibility Study.<h4>Background</h4>The introduction of oral anticancer therapies has, at least partially, shifted treatment from clinician-supervised hospital care to patient-managed home regimens.
