Introduction
COPD (chronic obstructive pulmonary disease), encompassing bronchitis and emphysema, is a persistent condition causing breathlessness, coughing, and exacerbations, leading to suboptimal health outcomes. Face-to-face visits with healthcare professionals may be impeded by COPD severity, frailty, and geographical distance. Telehealth technologies, facilitating remote healthcare through monitoring and consultations, could enhance outcomes for individuals with COPD.
What Is Chronic Obstructive Pulmonary Disease?
Chronic obstructive pulmonary disease (COPD) encompasses lung conditions causing breathing difficulties, with symptoms like shortness of breath, coughing, and increased mucus. COPD restricts airflow during exhalation, measurable through spirometry assessing lung function. As COPD progresses, symptoms worsen, impacting the quality of life and increasing the risk of hospitalization and death during exacerbations.
COPD involves two primary conditions:
-
Emphysema, arises from damage to the walls between air sacs in the lungs, making it challenging for the lungs to expel air.
-
Chronic bronchitis is a long-term issue caused by persistent irritation and inflammation in the airway linings, producing thick mucus and making breathing difficult.
Typically, individuals with COPD have a combination of emphysema and chronic bronchitis in varying degrees, and the severity of each condition varies from person to person.
What Is Telehealth and Remote Monitoring in COPD?
Telehealth, according to the World Health Organization, is defined as delivering healthcare services when patients and providers are separated by distance. Various forms of telehealth, including telephone, email, computer, monitoring, or video consultation, enable remote healthcare delivery. Remote monitoring, utilizing digital devices like web-based tools, allows the timely transfer of patient data, such as physiological parameters (oxygen saturation, blood pressure, etc.), to healthcare professionals.
This approach has the potential to detect early changes in symptoms, facilitate prompt intervention, and is known to reduce exacerbation severity, hospitalization frequency, and disease progression in COPD.
Continuous monitoring offers a more comprehensive understanding of a person’s condition than face-to-face consultations. Remote monitoring can be asynchronous, involving real-time technology for monitoring physiological parameters, live-streaming medical images, and video consultations.
Real-time remote consultations involve live interactions through video, telephone, or web-based applications, supplementing face-to-face visits. These remote strategies, whether monitoring or consultation, can be part of integrated care packages called ‘multi-component’ interventions.
What Is the Effect of Telehealth on COPD Management?
In economically developed regions, electronic tools for remotely assisting COPD patients are being implemented without a clear evidence base, necessitating an exploration of the existing evidence for the values or risks of such interventions.
Telehealthcare, aiming to detect and treat diseases early, could reduce morbidity and hospitalization costs. Despite substantial startup costs, the long-term benefits remain uncertain. COPD’s debilitating nature makes telehealthcare, with its mechanisms like patient education and remote monitoring, promising for reducing isolation. Clinical trials exploring telehealth interventions for COPD demonstrate varied results, with inconclusive evidence of their effectiveness in improving clinical outcomes.
Before the COVID-19 pandemic, telehealth interventions were widely adopted for stroke care, psychiatry, and rural care, but not extensively for COPD care. The pandemic’s impact on in-person COPD care was significant due to shortages of PPE (personal protective equipment) and concerns about SARS-CoV-2 transmission. Delays and reductions in face-to-face consultations, testing, and pulmonary rehabilitation occurred, contributing to stress, insomnia, and mental health issues in COPD patients.
Despite COPD patients being at higher risk for severe COVID-19, there was a 50 percent reduction in COPD hospitalizations during the pandemic, possibly influenced by infection control measures and increased telehealth availability. Healthcare providers rapidly shifted to telehealth, with a significant proportion adopting telemedicine for COPD care.
Barriers to telehealth implementation during the pandemic included patient, provider, and health system challenges. Financial barriers for providers were eased, but the sustainability of telehealth depends on reimbursing technical consultation fees. Telehealth is a permanent feature in healthcare systems, offering support between in-person visits, addressing healthcare challenges, and potentially reducing health disparities. However, issues like differential internet and smartphone access need attention.
Looking beyond the pandemic, telehealth’s role may expand with the help of implementation science and human-centered design. Implementation science studies how interventions impact healthcare, while human-centered design focuses on developing solutions optimized for end-user needs. The evolution of telehealth beyond substitution for in-person care to augmenting or creating entirely new models requires planning and assessment, with a human-centered approach facilitating appropriate and acceptable service offerings.
What Is the Role of Telerehabilitation in COPD?
Telerehabilitation, defined as the use of technologies for care and rehabilitation, operates through four service delivery models: face-to-face interactive video conferencing, tele-homecare with nurse coordination, telemonitoring with interactive tele-evaluation, and telecare where patients perform exercises under remote monitoring with therapist adjustments.
Telerehabilitation utilizes tools like phone calls, messages, emails, video phones, websites, mobile phones, video conferencing, electronic sensors, and programmable medical devices, benefiting patients with limited access to services, especially in rural/remote areas.
Its application timing includes post-hospital discharge or maintaining benefits such as functional independence, education, participation, physical change, early relapse detection, adherence, airway clearance, and exercise training. Despite its promise for cardiopulmonary diseases, clear evidence for telerehabilitation is still limited. Supervised training and counseling at home have shown safety, feasibility, and benefits for severe COPD patients.
What Are the Factors Considered in Telehealthcare?
Telehealthcare, as a complex intervention, encompasses various components such as education, planning assistance, emotional support, pragmatic advice, and remote monitoring. Its potential mechanisms for enhancing care and achieving cost savings include patient education, improved medication adherence, remote data collection, replacing face-to-face visits, early detection of disease exacerbations, reducing unscheduled visits, and preventing repeat hospitalizations. However, the active ingredients of telehealthcare require further theoretical exploration through qualitative studies.
Legal considerations in telemedicine involve the person transmitting data, the person receiving data, and the service provider(s). Informed consent, confidentiality, and data protection are crucial aspects. Risks associated with telemedicine include data security, health professionals’ responsibilities, and interoperability issues, emphasizing the need for updated legislation and standards.
Economically, the aging European population challenges healthcare budgets, making telehealth a potential solution. A meta-analysis suggests cost savings with telehealth, but its economic impact should be evaluated within the context of standard therapy and regional variations in homecare organizations. The global telemedicine market is growing, offering opportunities for new businesses.
Despite the potential benefits, variable telemedicine models exist for COPD patients, requiring more evidence for their effectiveness. Factors like age, education, technological experience, and home environment influence a patient’s ability to use telemedicine. Future research areas include evaluating telemedicine’s effects on clinical outcomes, health services, and resource utilization. Barriers, such as technological limitations and caregiver training, must be addressed for wider telemedicine adoption.
Conclusion
Telehealth and remote monitoring present promising avenues for enhancing care in COPD. These technologies offer various benefits, including improved patient education, enhanced adherence to treatment regimens, remote data collection, and early detection of disease exacerbations. Legal considerations, data security, and interoperability issues need careful attention.
