Summary of Reviewed Papers from Section 3.2.

Ref. Purpose Results
[44] To examine algorithms that use BW and non-invasive transthoracic bio-impedance to predict decompensation in HF patients. Data from a bio impedance vest predicted events better than weight data.
[46] To investigate the relationship between daily BW and II in patients with HF Combining BW and impedance data can decrease false-detection rate to clinically acceptable levels and achieved a better performance than BW alone.
[47] To examine the sensitivity and false alarm rate of predicting HF events between changes in daily BW and II in HF patients. Monitoring of II achieved a significantly higher sensitivity and lower false alarm rate in predicting of HF events compared with BW monitoring.
[48] To evaluate the use of a combination of HF device diagnostics data in predicting clinical deterioration in HF patients with systolic left ventricular dysfunction. Patients that had positive HF device diagnostics as specified were 4.8 times more likely to have an HF hospitalization in the next month with pulmonary signs or symptoms.
[49] To evaluate the positive predictive value (PPV) and sensitivity of II monitoring for chronic HF patients. Fluid index derived from II had low PPV and sensitivity at the early stages after implantation of a device.
[50] To investigate the safety and clinical effects that remote monitoring will have on HF patients that are implanted with a CRT-D with advanced diagnostics. For HF patients that were implanted with a CRT-D, mortality, and risk of cardiovascular or device-related hospitalizations was not reduced by remote monitoring.
[51] To determine whether the implementation of a schedule screening and patient-centered educational approach to II measurements would result in the decrease of chronic HF hospitalizations. There was a low incidence of chronic HF hospitalizations, especially in patients with decreased intrathoracic impedance.
[52] To determine whether early automated alarms of fluid status using telemonitoring can reduce HF-related events in patients. There was no significant improvement using the telemonitoring with II measurements. The automated alerts did not result in a decrease in hospitalizations.
