- ItemA new telemonitoring system intended for chronic heart failure patients using mobile telephone technology--feasibility study.(2011-11-14) Winkler, Sebastian; Schieber, Michael; Lücke, Stephanie; Heinze, Peter; Schweizer, Thomas; Wegertseder, Dominik; Scherf, Michael; Nettlau, Herbert; Henke, Sascha; Braecklein, Martin; Anker, Stefan D; Koehler, FriedrichBACKGROUND Remote monitoring is one modality of structured care in chronic heart failure The purpose of this study was to evaluate the feasibility of a new wireless telemonitoring system via a mobile phone network METHODS Portable home devices for electrocardiogram blood pressure body weight and self assessment measurements were connected via Bluetooth to a personal digital assistant PDA that performs automated encrypted transmission via mobile phone Two telemedical centres were set up RESULTS 30 healthy volunteers were enrolled and followed for 26 days A total of 4002 single measurements were taken 133 37 per person No data was lost or incorrectly allocated 880 of 937 94 of the ECG recordings had sufficient diagnostic quality for rhythm analysis and single beat measurements 50 continuous ECG streams 312 min without disruption were performed Total system availability was 96 6 including that of the mobile phone network CONCLUSIONS Mobile phone technology is suitable for continuous and secure medical data transmission To evaluate the clinical use in chronic heart failure patients a large multicentre randomized controlled trial ClinicalTrials gov Identifier NCT00543881 was started
- ItemTelemedical Interventional Management in Heart Failure II (TIM-HF2), a randomised, controlled trial investigating the impact of telemedicine on unplanned cardiovascular hospitalisations and mortality in...(0000-00-00) Koehler, Friedrich; Koehler, Kerstin; Deckwart, Oliver; Prescher, Sandra; Wegscheider, Karl; Winkler, Sebastian; Vettorazzi, Eik; Polze, Andreas; Stangl, Karl; Hartmann, Oliver; Marx, Almuth; Neuhaus, Petra; Scherf, Michael; Kirwan, Bridget-Anne; Anker, Stefan DBACKGROUND Heart failure HF is a complex chronic condition that is associated with debilitating symptoms all of which necessitate close follow up by health care providers Lack of disease monitoring may result in increased mortality and more frequent hospital readmissions for decompensated HF Remote patient management RPM in this patient population may help to detect early signs and symptoms of cardiac decompensation thus enabling a prompt initiation of the appropriate treatment and care before a manifestation of HF decompensation OBJECTIVE The objective of the present article is to describe the design of a new trial investigating the impact of RPM on unplanned cardiovascular hospitalisations and mortality in HF patients METHODS The TIM HF2 trial is designed as a prospective randomised controlled parallel group open with randomisation concealment multicentre trial with pragmatic elements introduced for data collection Eligible patients with HF are randomised 1 1 to either RPM usual care or to usual care only and are followed for 12 months The primary outcome is the percentage of days lost due to unplanned cardiovascular hospitalisations or all cause death The main secondary outcomes are all cause and cardiovascular mortality CONCLUSION The TIM HF2 trial will provide important prospective data on the potential beneficial effect of telemedical monitoring and RPM on unplanned cardiovascular hospitalisations and mortality in HF patients TRIAL REGISTRATION ClinicalTrials gov Identifier NCT01878630
