Understanding remote patient monitoring system: functions and technology

After the pandemic, remote patient monitoring has become more popular than ever before. Many healthcare providers have deployed remote monitoring systems and devices in their healthcare process and benefited from them. If you are trying to understand the development of RPM, let’s dive into this journey to figure out the technology aspects of a remote patient monitoring system.

Users of remote patient monitoring system

It’s important for healthcare providers and developers of the RPM system to determine the users. Without knowing the users, it’s hard to find out other factors. Depending on whether the system are packaged or tailored, users of remote patient monitoring systems are categorized into these below:

Patients

Patients suffering from chronic diseases such as diabetes, hypertension, or heart conditions benefit from RPM by allowing them to actively participate in their care. They use RPM devices to monitor vital signs, report symptoms, and adhere to treatment plans.

Healthcare providers

Physicians and Nurses: Healthcare professionals leverage RPM data to monitor patients remotely, assess health trends, and make informed decisions about treatment plans. RPM facilitates early detection of issues, reducing the need for frequent in-person visits.

Specialists: Specialists, such as cardiologists or endocrinologists, can use RPM to monitor specific health parameters relevant to their areas of expertise, enabling targeted and specialized care.

Care coordinators

Professionals who are responsible for coordinating patient care, usually are care managers and coordinators. They will use RPM data to ensure that patients follow the treatment plans, address any concerns, and facilitate communication between patients and healthcare providers.

Home health agencies

Agencies providing home healthcare services utilize RPM to extend their reach beyond traditional visits. Remote monitoring allows them to assess patients' conditions, provide guidance, and intervene as needed.

Telehealth platforms

RPM systems are often integrated with telehealth platforms, allowing for virtual consultations and facilitating seamless communication between patients and healthcare providers.

Pharmaceutical companies

Pharmaceutical companies conducting clinical trials or research studies can utilize RPM to remotely monitor participants, collect relevant health data, and ensure compliance with study protocols.

Patients' families and caregivers

RPM systems enable family members and caregivers to actively participate in the care of their loved ones. They can receive alerts, monitor vital signs, and communicate with healthcare providers, fostering a collaborative approach to patient care.

Health IT professionals

Professionals responsible for the implementation and maintenance of RPM systems ensure that the technology functions seamlessly, data is securely transmitted, and integrations with electronic health records (EHRs) and other systems are optimized.

Researchers and academia

Researchers may use data from RPM systems for studies related to population health, the effectiveness of remote monitoring, and the impact of technology on healthcare delivery.

7 important functions of a remote patient monitoring system

Depending on each healthcare providers’ purposes, remote patient monitoring systems may have different functions. Still, there are some basic and important functions that are required in every RPM system.

Continuous vital sign monitoring

A RPM system can monitor and track patients' vital signs in real-time. Early detection of abnormalities, allowing timely intervention and prevention of complications. Through digital health devices, RPM systems will collect and monitor health parameters such as: heart rate, blood pressure, respiratory rate, oxygen saturation, and other relevant vital signs.

Chronic disease management

This function in the remote patient monitoring system will support patients with chronic conditions in managing their health at home. By following patients through the system, healthcare staff can improve adherence to treatment plans, reduce hospitalizations, and enhance overall disease management.

Some chronic diseases can be effectively utilized in the RPM system such as diabetes, hypertension, heart failure, chronic obstructive pulmonary disease (COPD), etc.

Medication adherence monitoring

Medication adherence monitoring allows healthcare staff to track and ensure patients' adherence to prescribed medication regimens. This prevents medication errors, improves patient compliance, and optimizes treatment outcomes.

RPM can integrate with medication dispensers or reminders to activate this function.

Telehealth consultations

This function facilitates virtual consultations between patients and healthcare providers. Features of telehealth consultations might be video conferencing, secure messaging, and virtual visits. 

Healthcare providers can increase access to care, reduce the need for in-person visits, and enhance patient-provider communication.

Fall detection and prevention

Monitoring and detecting falls, especially in elderly or at-risk patients, are an important function of the RPM system. Prompt of the system will respond to falls, reducing the risk of injuries and hospitalizations.

To set up this function, the RPM system should be included in wearable devices with fall detection capabilities.

Wearable health devices integration

By monitoring through fitness trackers, smartwatches, and other health wearables, RPM systems can integrate data from wearable devices to provide a comprehensive health profile. From that, healthcare providers can enrich data for a comprehensive view of patients' health and lifestyle.

Remote diagnostics

Enabling remote diagnostic testing and monitoring can support timely intervention and treatment effectiveness in disease progression.

Some examples of remote diagnostics are remote blood glucose monitoring, spirometry, and other diagnostic tests.

Automated Alerts and Notifications

This function can generate alerts and notifications based on predefined thresholds. RPM systems will automatically alert for abnormal vital signs or critical events to the healthcare staff or caregivers. It provides timely response to critical situations, reducing the risk of adverse outcomes.

Which health devices can be integrated with remote patient monitoring system

The choice of devices depends on the specific health parameters to be monitored and the patient's medical condition. Here are some common health devices that can be integrated with an RPM system:
