How to use remote patient monitoring successfully in cardiac and pulmonary patients: a realist review

Abstract

\n \n \n Type of funding sources: Public hospital(s). Main funding source(s): Queensland Health\n \n \n \n Remote patient monitoring (RPM) is an underutilised telehealth intervention that can enhance self-management of cardiovascular and pulmonary disease and reduce acute care use. However, studies of effectiveness of RPM interventions vary widely. This study aimed to explain the variation in outcomes related to RPM interventions within cardiac and pulmonary populations. Specifically, we aimed to answer why some RPM interventions are more successful than others in reducing demand on acute care services.\n \n \n \n In brief, search terms for remote monitoring and acute care utilisation were used across three electronic databases: PubMed, EMBASE and CINAHL. The search, conducted in October 2020, included articles published in the last five years (2015-2020). Articles were included if they used RPM to monitor an individual’s biometrics (e.g. heart rate, blood pressure) from a distance while they are not in hospital. Realist review methodology was used to enable exploration of how, why and for whom interventions do and do not work.\xa0 Outcomes were evaluated to determine contextual factors and potential mechanisms that led to variation in cardiac and pulmonary intervention outcomes.\n \n \n \n After screening, 91 articles met the eligibility criteria and were included. We found that across a broad range of RPM interventions 31 factors emerged that are likely to impact the effectiveness of cardiac and pulmonary RPM innovations. These were synthesised into six theories of intervention success: 1) targeting populations at high risk; 2) accurately detecting a decline in health; 3) providing responsive and timely care; 4) personalising care; 5) enhancing self-management and, 6) ensuring collaborative and coordinated care.\n \n \n \n \xa0While RPM interventions are complex, if they are designed with patients, providers and the implementation setting in mind and with the key variables identified within this review \xa0incorporated, it is more likely that they will be effective at reducing acute hospital events.\n
