Remote monitoring embraces data collection, data analysis, clinical decision-making and an effector arm that provides therapy instructions to the patient, or their carer or a near-to-patient healthcare professional. Disease-specific monitoring technologies are increasingly available. The design and implementation of appropriate care pathways is critical to the success of remote monitoring, as data acquisition alone is of no inherent value without an appropriate and timely response. A further key element affecting widespread adoption of remote monitoring is reimbursement, which is highly variable. It is, as yet, an unproven assumption that remote monitoring can reduce healthcare costs. These issues are critically discussed.
