Types of telehealth
Telehealth manifests in several forms, each driven by the need to connect with patients despite their location. Telehealth is health data collection and health data transfer, and communication between caregiver and patient. Because of this wide definition, there are many different types of telehealth. The following are some of the most prominent:
Remote Patient Monitoring. Beginning with a critical reason for telehealth’s being is remote patient monitoring. Remote patient monitoring allows caregivers the ability to monitor patients’ health remotely. Remote patient monitoring is a highly effective method of caring for patients when outpatient care is not feasible. Also, when the patient’s health condition is not life-threatening especially chronic conditions –– for example, diabetes and COPD –– remote patient monitoring cuts down the time a patient spends in the hospital, when necessary, and lets them recover in an outpatient setting.
Remote patient monitoring technology shares patient medical data regularly with the patient’s care team. This technology transmits the information automatically, leading to active ongoing care monitoring in a more passive data collection process. If any problems with the patient arise, members of the care team can respond immediately. Telehealth technology practically exists in these situations. Letting patients self-monitor and report regularly to their caregiver alleviates burdens on the health system and allows for resources to be spent on more pressing issues.
Store-and-forward. Store-and-forward telehealth is another primary reason for telehealth being. Store-and-forward telehealth makes patient records and medical data more accessible across long distances. Medical data, including images, test results, bio-signals, lab reports, and substantial documents can be acquired and transmitted (stored-and-forwarded) across great distances. Also, this method doesn’t require simultaneous attention of the delivering and receiving parties. The information can be sent and received at separate times and collection points. A caregiver can collect the data, upload it and send it, and leave the data for review by another provider at a later time.
Real-time Telemedicine. Real-time telehealth means real-time care between a doctor and patient at any time from anywhere. Real-time telehealth includes any two-way communications involving a connection via video conferencing and phone consultations, that connect providers and patients. Assessments of medical history, visual examinations for many health conditions, psychiatric evaluations, and other types of care can be carried out through real-time telehealth.
Physician-to-physician consultations. Through telehealth technologies, physicians can connect to provide a broader range of care. For example, a primary physician can easily access a specialist without the need for travel, but with more clarity than just a phone. Physicians also can gain greater access to a broader range of specialists that they may have at their immediate disposal. Telehealth creates the ability to share patient information quickly and can improve patient outcomes in part because of the immediacy of the care available.
Medical Imaging. Modern telehealth technology accelerates how X-rays, scans, and other images are shared between locations. By sharing these images, they can be reviewed at any time by any licensed radiologist connected to the system. Thus, patients are no longer at the mercy of their local radiologist for review of their images. Many organizations contract with networks of radiologists all over the country, who review images remotely as required. For example, a hospital produces an image onsite, transmits the image to a cardiologist across the country, and received a response and analysis within a short time versus days or weeks.
Telehealth technology should be secure and protect patient privacy and meet the strict patient protections required by the Health Insurance Portability and Accountability Act (HIPAA). Systems like Skype and FaceTime are not HIPAA-compliant so are not appropriate for telehealth use.
