Remote monitoring of patients with cardiac implantable electronic devices: a Southeast Asian, single-centre pilot study

Abstract

INTRODUCTIONRemote monitoring of cardiac implantable electronic devices (CIED) has been shown to improve patient safety and reduce in-office visits. We report our experience with remote monitoring via the Medtronic CareLink ® network. METHODSPatients were followed up for six months with scheduled monthly remote monitoring transmissions in addition to routine in-office checks. The efficacy of remote monitoring was evaluated by recording compliance to transmissions, number of device alerts requiring intervention and time from transmission to review. Questionnaires were administered to evaluate the experiences of patients, physicians and medical technicians. RESULTSA total of 57 patients were enrolled; 16 (28.1%) had permanent pacemakers, 34 (59.6%) had implantable cardioverter defibrillators and 7 (12.3%) had cardiac resynchronisation therapy defibrillators. Overall, of 334 remote transmissions scheduled, 73.7% were on time, 14.5% were overdue and 11.8% were missed. 84.6% of wireless transmissions were on time, compared to 53.8% of non-wireless transmissions. Among all transmissions, 4.4% contained alerts for which physicians were informed and only 1.8% required intervention. 98.6% of remote transmissions were reviewed by the second working day. 73.2% of patients preferred remote monitoring. Physicians agreed that remote transmissions provided information equivalent to in-office checks 97.1% of the time. 77.8% of medical technicians felt that remote monitoring would help the hospital improve patient management. No adverse events were reported.

Prospective evaluation of integrated device diagnostics for heart failure management: results of the TRIAGE‐HF study

“…Moreover, longitudinal measurement, with dynamic baseline adjustment using individual patients as their own control, more accurately captures the patient journey. Quality of life showed a trend towards improvement in TRIAGE‐HF, a finding consistent across other trials of remote monitoring …”

“…Quality of life showed a trend towards improvement in TRIAGE-HF, a finding consistent across other trials of remote monitoring. [15][16][17] Cowie and colleagues, 8 in their validation study of HFRS, hypothesized that this integrated diagnostic tool could be used to guide HF practitioners on when to collect additional clinical information that in turn could guide care. TRIAGE-HF has now demonstrated a strong correlation between HFRS and clinical status in a prospective setting, confirming the value of this approach.…”

Remote control improves quality of life in elderly pacemaker patients versus standard ambulatory‐based follow‐up

“…Recent studies provide an insight in the potential trigger of the improved HRQoL, like reduced burden of outof-home visits, feeling safer, and being closely monitored by competent health care professionals with negligible impact of tasks to be fulfilled to comply with monitoring. 33…”

Changes in the practice of cardiology: therapies at the forefront of science

“…In a pilot study by Lim et al, 57 patients with CIED were followed up for six months using scheduled wireless remote transmissions, in addition to routine clinic visits. (11) This study highlights the feasibility of such technology to improve patient quality of life, patient safety by earlier detection of problems and compliance to device monitoring. However, the study also underscores the need for proper information filtering in the era of 'big data'.…”
