Incorporating RPM in chronic disease management can significantly improve an individual’s quality of life. It allows patients to maintain independence, prevent complications, and minimize personal costs [1]. RPM facilitates these goals by delivering care right to the home. In addition, patients and their family members feel comfort knowing that they are being monitored and will be supported if a problem arises. This is particularly important when patients are managing complex self-care processes such as home hemodialysis [2]. Key features of RPM, like remote monitoring and trend analysis of physiological parameters, enable early detection of deterioration; thereby, reducing number of emergency department visits, hospitalizations, and duration of hospital stays [3]. The need for wireless mobility in healthcare facilitates the adoption of RPM both in community and institutional settings. The time saved as a result of RPM implementation increases efficiency, and allows healthcare providers to allocate more time to remotely educate and communicate with patients. [4]
Technological components
The diverse applications of RPM lead to numerous variations of RPM technology architecture. However, most RPM technologies follow a general architecture that consists of four components. [5]:
- Sensors on a device that is enabled by wireless communications to measure physiological parameters.
- Local data storage at patients’ site that interfaces between sensors and other centralized data repository and/or healthcare providers.
- Centralized repository to store data sent from sensors, local data storage, diagnostic applications, and/or healthcare providers.
- Diagnostic application software that develops treatment recommendations and intervention alerts based on the analysis of collected data.
Depending on the disease and the parameters that are monitored, different combinations of sensors, storage, and applications may be deployed. [5].
Applications
Physiological data such as blood pressure and subjective patient data are collected by sensors on peripheral devices. Examples of peripheral devices are: blood pressure cuff, pulse oximeter, and glucometer. The data are transmitted to healthcare providers or third parties via wireless telecommunication devices. The data are evaluated for potential problems by a healthcare professional or via a clinical decision support algorithm, and patient, caregivers, and health providers are immediately alerted if a problem is detected. [3]. As a result, timely intervention ensures positive patient outcomes. The newer applications also provide education, test and medication reminder alerts, and a means of communication between the patient and the provider. [3] The following section illustrates examples of RPM applications, but RPM is not limited to those disease states.
Dementia and falls
For patients with dementia that are at risk for falls, RPM technology promotes safety and prevents harm through continuous surveillance. [3]. RPM sensors can be affixed to the individual or their assistive mobility devices such as canes and walkers. [3]. The sensors monitor an individual’s location, gait, linear acceleration and angular velocity, and utilize a mathematical algorithm to predict the likelihood for falls, detect movement changes, and alert caregivers if the individual has fallen. [3]. Furthermore, tracking capabilities via Wi-Fi, global positioning system (GPS) or radio frequency enables caregivers to locate wandering elders. [3].
Diabetes
Diabetes management requires control of multiple parameters: blood pressure, weight, and blood glucose. The real-time delivery of blood glucose and blood pressure readings enables immediate alerts for patient and healthcare providers to intervene when needed. There is evidence to show that daily diabetes management involving RPM is just as effective as usual clinic visit every 3 months.[6].
Congestive heart failure
A systematic review of the literature on home monitoring for heart failure patients indicates that RPM improves quality of life, shortens duration of stay in hospitals, decreases mortality rate, and reduces costs to the healthcare system. [7].
Early adopter: Veterans Health Administration
The Veterans Health Administration (VHA), United States’ largest integrated healthcare system, is highly involved in the implementation and evaluation of RPM technologies. It has expanded use of RPM beyond common chronic disease applications, to post-traumatic stress disorder, cancer and palliative care[4]. VHA’s findings indicate improvements in a wide range of metrics, including decrease in emergency department visits, hospitalizations, and nursing home admissions [4]. Findings from the VHA Care Coordination/Home Telehealth program show that RPM deployment resulted in significant savings to the organization.[8].
Whole System Demonstrator Trial in UK
The UK’s Department of Health’s Whole System Demonstrator (WSD)[9] launched in May 2008. It is the largest randomised control trial of telehealth and telecare in the world, involving 6191 patients and 238 GP practices across three sites, Newham, Kent and Cornwall. The trials were evaluated by: City University London, University of Oxford, University of Manchester, Nuffield Trust, Imperial College London and London School of Economics.
- 45% reduction in mortality rates
- 20% reduction in emergency admissions
- 15% reduction in A&E visits
- 14% reduction in elective admissions
- 14% reduction in bed days
- 8% reduction in tariff costs
In the UK, the Government's Care Services minister, Paul Burstow, has stated that telehealth and telecare would be extended over the next five years (2012-2017) to reach three million people.[10]
Limitations
RPM is highly dependent on the individual’s motivation to manage their health. Without the patient’s willingness to be an active participant in their care, RPM implementation will likely fail. Cost is also a barrier to its widespread use. Devices and peripherals currently cost thousands of dollars, and for RPM to take hold in health care, costs need to come down to the $300 to $500 range.[11] There is a lack of reimbursement guidelines for RPM services, which may deter its incorporation into clinical practice.[5]. The shift of accountability associated with RPM brings up liability issues [5]. There are no clear guidelines in respect to whether clinicians have to intervene every time they receive an alert regardless of the urgency. The continuous flow of patient data requires a dedicated team of health care providers to handle the information, which may, in fact, increase the workload. Although technology is introduced with the intent to increase efficiency, it can become a barrier to some healthcare providers that are not technological. There are common obstacles that health informatics technologies encounter that applies to RPM. Depending on the comorbidities monitored, RPM involves a diverse selection of devices in its implementation. Standardization is required for data exchange and interoperability among multiple components. Furthermore, RPM deployment is highly dependent on an extensive wireless telecommunications infrastructure, which may not be available or feasible in rural areas. Since RPM involves transmission of sensitive patient data across telecommunication networks, information security is a concern.[5]
Controversy
Published by the New England Journal of Medicine, a randomized controlled trial involving congestive heart failure patients concluded that the use of telemonitoring failed to provide a benefit over usual care [12]. The telemonitoring patient group was instructed to call a designated number daily, and answer a series of questions about their symptoms using a keypad [12]. Clearly, the process described by Chaudhry et al. (2010) differs from the RPM methodology illustrated in the overview, which involves actual collection and transmission of physiological data through point-of-care devices. With articles [13] [14] from Forbes associating RPM with the negative findings by Chaudhry et al. (2010), it may be difficult to clear the misconception that telemonitoring is synonymous with remote patient monitoring. The lack of standardization of RPM nomenclature and definition makes it difficult to differentiate between different forms of patient monitoring involving technology.
