The quality of the evidence was very low and did not demonstrate a clear effect with the confidence interval ranging from a decrease and increase in all-cause mortality.The outcome all-cause hospitalisations contained the same study and was rated low quality, and also showed a clinically important increase in hospitalisations (again associated with wide confidence). For the outcome QoL a single study (n=50) rated as very low quality showed a clinically important improvement in QoL using both the MLWHF and KCCQ HRQoL scales.

ISBN: 978-1-4731-3093-7 The studies contained within the following strata compared telemonitoring to usual care. There was also a high degree of heterogeneity between the interventions with technology used, interface and level of data acquisition varying from study to study. Recent admission For the outcome all-cause mortality, 9 studies (n=1480) were included. The evidence was low quality and showed a clinically important reduction in deaths. The outcome all-cause hospitalisation contained 8 studies (n=1400) was very low quality and showed a clinically important reduction in hospitalisations. This outcome displayed a significant level of heterogeneity (I2 =83%), unexplained by subgroup analysis for age, year of publication and intensity of intervention which was taken into consideration when judging the quality of the evidence. For the outcome QoL the evidence ranged from high to very low quality. High quality evidence (1 study, n=280) was found for the scales SF-12 and HDS, which both showed no clinical effect. Very low quality evidence was found for the SF-36 scale (1 study, n=57), the mental component summary showed a clinically important improvement in QoL, while the physical component showed no clinical effect. Community For this strata a single study (n=20) reported all-cause mortality alone.
