TRUST was initiated in 2005, preceding the call from the Heart Rhythm Society to develop remote technologies, and coincided with well-publicized recalls which heightened patients' awareness for monitoring. The remote technology used in TRUST Home Monitoring (HM) has demonstrated excellent levels (>95%) of patient acceptance and satisfaction.2 It is likely then that patients' motivation propelled TRUST to rapid enrollment and early completion. No TRUST patients assigned to HM crossed over during the study, and 98% elected to retain this follow-up mode on trial conclusion, representing the outcome of the shared decision. In contrast, conventional care was characterized by follow up attrition, indicating how onerous patients find scheduled clinic visits.It is possible that patient notification of detection of asymptomatic problems (eg, a broken lead) or nonsustained events is anxiety-provoking. However, inaction is more hazardous. Monitoring hardware performance is a physician responsibility embodied in recent Heart Rhythm Society position statements and often demanded by post-2005 patients.3 Conventional monitoring significantly underreports these events compared to HM.4 Nonsustained arrhythmia notifications which may also be triggered by, for example, lead noise/T wave oversensing, may cause battery depletion and presage shock delivery causing patient morbidity. Shock burden reduction, especially if inappropriate, is a major current concern. HM's early detection of such asymptomatic problems provides an opportunity for early preventative action.4Adjudication of actionability of patient data is the cornerstone of clinical management. HM may facilitate this decision making process for system function as well as patient condition. Automatic longitudinal databasing generates baseline trends with automatic notification of parameter deviation. This lays a foundation for future clinical outcomes studies (not in TRUST's purview) especially for heart failure for which a variety of implantable sensors are under development. The success of these depends on continuous monitoring, accessibility of collected data, and notification of asymptomatic deviation from individually established trends, to permit preemptive clinical intervention. The threat that such event notifications needlessly increase unscheduled visits was tested in TRUST. Notifications occurred infrequently (median <2 per patient per year) yet were valuable since face-to-face encounters triggered were highly actionable (>50%).5 Problem discovery and clinical response (ie, the aims of monitoring) are therefore improved by utilizing this exception-based care model with HM. Importantly, TRUST supported continued face-to-face to follow up with heart failure physicians.We question the validity of Dr Matlock's comparison to prostate-specific antigen screening. HM purpose is to provide near-continuous surveillance for early detection of changes in patients with already declared disease, considered at high risk for subsequent problems, and to monitor a therapy with established efficacy (ie, implantable device performance). TRUST illustrates a mechanism for improved execution of this necessary responsibility.3 This philosophy is separate to population screening for disease in which value will be determined by disease prevalence, the test's predictive value, and the efficacy of treatment available.TRUST illustrates how the rich diagnostic resources of implantable devices may be accessed in an efficient and timely manner to enhance patient care.Niraj Varma, MA, DM, FRCP Cardiac Pacing and Electrophysiology Cleveland Clinic Cleveland, OHBruce S.
