The ability of patients to self-monitor is deemed to be a critical tool in reducing the healthcare effects of chronic disease factors. The convergence of new measurement technologies, patient demographics and managed care cost initiatives is driving patient monitoring for a number of conditions from caregiver facilities and into homes. The key enablers of this significant shift are technological advances that provide accurate readings in a format that consumers can understand, clearly indicating when a follow-up visit to a caregiver is needed. Because of the associated morbidity and mortality and the cost to society, hypertension is an important public health challenge. Systems that allow patients to share readings with physicians electronically have already been introduced.
