Telemedicine-based approach for obstructive sleep apnea management: building evidence

Could an external Medical Center with telemonitoring help in home positive airway pressure treatment? A pilot study

PURPOSE

Telemedicine is useful for home management of sleep disordered breathing (SDB). However, the number of patients with SDB is high and public resources are low. The aim of this pilot study, conducted by the Universities of Pisa and Palermo, was to assess whether an external Medical Center, based on telemonitoring, could help in the management of patients on home positive airway pressure (PAP) treatment.

METHODS

The management model included the following professional figures: the sleep physician, the local home care provider performing diagnostic studies and home PAP titration, and the external Medical Center monitoring PAP therapy alerts. A dedicated App allowed patients to answer questionnaires, receive alerts and contact the external Medical Center. Data on mask leakage, hours of use and efficacy were available on a web platform. Patients were evaluated with videocalls at 1, 2 and 4 months and as needed.

RESULTS

We enrolled 30 subjects, 27 patients received Continuous PAP and 3 patients received Bilevel devices. Five patients withdrew during titration and 1 during follow-up. The number of interventions for technical problems requested by patients to the external Medical Center was highly variable. During the titration phase the interventions required were 2.1 ± 2.0 (range 0-11), while during the 4-month follow-up they were 6.0 ± 4.5 (range 0-18). At the end of follow-up, 93% of patients were satisfied by the telemedicine protocol.

CONCLUSION

A model of telemedicine using an external Medical Center can help in the home management of patients with SDB during both home titration and long-term treatment. FISR2020IP_02014 Project (MUR). May 2021.

Unmasking the Complex Interplay of Obesity Hypoventilation Syndrome, Heart Failure, and Sleep Dysfunction: A Physiological and Psychological Perspective in a Digital Health World

Obesity hypoventilation syndrome (OHS) is a multifaceted condition characterized by significant respiratory, cardiovascular, and psychological consequences. Positive airway pressure (PAP) therapy remains the cornerstone treatment, improving respiratory function, neurocognition, and mental health disorders such as depression and anxiety. However, its long-term impact on quality of life, physical activity, and broader health outcomes is not fully understood. Challenges such as residual apnoea/hypopnea index, reduced physical activity, and impaired quality of life persist despite high adherence rates. Factors like hypercapnia and daytime respiratory symptoms play a pivotal role in patient outcomes, underscoring the need for strategies beyond adherence alone. This review explores the interplay between OHS, heart failure, and sleep dysfunction, advocating for personalized PAP settings, targeted management of residual respiratory events, and enhanced patient education. Digital health technologies, including remote monitoring and feedback systems, present promising tools to optimize care delivery and foster holistic management. By integrating physiological, psychological, and digital health perspectives, this narrative review aims to advance understanding and improve outcomes for patients with OHS and other complex sleep-disordered breathing conditions.

Management of CPAP Follow-up by Telemonitoring in Obstructive Sleep Apnea: The PROTEUS Project

Purpose

CPAP is the standard treatment for obstructive sleep apnea (OSA), but as many as 50% of patients discontinue its use, within three years. The PROTEUS project aims to enhance CPAP adherence through telemonitoring.

Patients and Methods

OSA patients undergoing CPAP treatment since July 2018, had an in-person reassessment after three months, followed by quarterly telemonitoring by providers, who intervened in cases of poor adherence (less than 4 h·night-1 or less than 70% of days), excessive mask leakage, or elevated residual apnea-hypopnea index (rAHICPAP).

Results

A total of 486 (~87%) out of 558 patients analyzed remained adherent to CPAP after five years. The average rAHICPAP was 3.95 ± 5.25 events·h-1, the average CPAP usage was 6.35 ± 1.72 hours. Elevated mask leakage occurred in 25% of patients. No significant differences were found between sexes.

Conclusion

The PROTEUS project showed promising results in supporting long-term CPAP adherence. However, further research is needed to validate its long-term impact and wider applicability in OSA management.

Telephone follow-up as a substitute for standard out-clinic follow-up in CPAP therapy for obstructive sleep apnea patients: a randomized controlled trial

PURPOSE

This study assessed the feasibility of telephone follow-up consultations (TC) using an online data sharing and editing function (Airview™), as alternative to standard out-clinic follow-up consultations (SC) on adherence to continuous positive airway pressure (CPAP) in obstructive sleep apnea (OSA) patients. Furthermore, we investigated compliance to follow-up consultations and examined potential influencing factors, including baseline AHI (apnea-hypopnea-index), age, and distance from home to the hospital on consultation compliance.

METHODS

Two hundred OSA patients, with AHI ≥ 5 were randomly assigned (1:1) to receive TC or SC with follow-up after one month and 12 month of CPAP initiation. Adherence goal was defined as achieving ≥ 4 h of CPAP use daily in 70% of the days in a 365-days period.

RESULTS

The proportion of participants achieving CPAP adherence was non-significantly lower in the TC group compared to the SC group (TC: 30% versus SC: 36%, adjusted OR 0.84, p = 0.59). Of participants who completed the study, the TC group had a significant average of 107 min less use of CPAP compared to the SC group (p = 0.048). However, a higher proportion of participants was compliant to consultations in the TC group. The only influencing factor found was increasing baseline AHI, which might be a predictor for compliance to consultations and adherence to CPAP therapy.

CONCLUSION

TC might serve as substitute for SC in some part of the OSA population. If TC becomes a part of CPAP therapy management, it is important to consider patient characteristics and treatment-related issues to prevent decline in adherence.

The Role of Telemedicine in Children with Obstructive Sleep Apnea Syndrome (OSAS): A Review of the Literature

The advent of telemedicine marked a significant turning point in the healthcare landscape, introducing a revolutionary approach to the delivery of medical care. Digital technologies easily connect health professionals and patients, overcoming geographical and temporal barriers. Telemedicine has been used for sleep disorders including obstructive sleep apnea syndrome (OSAS) since the mid-1990s. In adult patients with OSAS, telemedicine is helpful both for consultation and diagnosis, the latter obtained through remote recordings of oxygen saturation and further parameters registered with telemonitored respiratory polygraphy or polysomnography. Remote monitoring can be used to follow up the patient and verify adherence to daily treatments including continuous positive airway pressure (CPAP). In children, studies on the role of telemedicine in OSAS are scarce. This narrative review aims to describe the application of telemedicine in children with obstructive sleep apnea syndrome (OSAS), assessing its advantages and disadvantages. In patients with OSA, telemedicine is applicable at every stage of patient management, from diagnosis to treatment monitoring also in pediatric and adolescent ages. While telemedicine offers convenience and accessibility in healthcare delivery, its application in managing OSAS could be associated with some disadvantages, including limitations in physical examination, access to diagnostic tools, and education and counseling; technology barriers; and privacy concerns. The adoption of a hybrid approach, integrating both in-office and virtual appointments, could effectively meet the needs of children with OSAS. However, more studies are needed to fully assess the effectiveness and safety of telemedicine in the pediatric population.

Telemedicine for obstructive sleep apnea syndrome: An updated review

Telemedicine (TM) is a new medical service model in which computer, communication, and medical technologies and equipment are used to provide "face-to-face" communication between medical personnel and patients through the integrated transmission of data, voice, images, and video. This model has been increasingly applied to the management of patients with sleep disorders, including those with obstructive sleep apnea syndrome (OSAS). TM technology plays an important role in condition monitoring, treatment compliance, and management of OSAS cases. Herein, we review the concept of TM, its application to OSAS, and the related effects and present relevant application suggestions and strategies, which may provide concepts and references for OSAS-related TM development and application.

[Factors affecting adherence to CPAP therapy in patients with obstructive sleep apnea syndrome]

OBJECTIVE

Analysis of factors affecting adherence to continuous positive airway pressure (CPAP) therapy in patients with obstructive sleep apnea (OSA).

MATERIAL AND METHODS

The literature search was carried out using the databases PubMED, Google Scholar, E-library, Cyberleninka for the period 2013-2023 and included reviews and original articles.

RESULTS

The main groups of factors affecting adherence to CPAP therapy in patients with OSA have been established. These include sociodemographic and socioeconomic factors, the severity of OSA and the severity of clinical symptoms, and psychosocial factors. Strategies that can improve adherence were identified (educational technologies for patients, telemedicine technologies, behavioral therapy, modern technical interventions).

CONCLUSION

Factors that improve adherence to CPAP therapy are high levels of education and income, more severe OSA forms accompanied by daytime sleepiness, support from the patient's spouse and social support. Factors such as low levels of education and income, smoking, symptoms of depression and hypochondria, as well as side-effects worsen adherence to CPAP therapy, including refusal to continue treatment. It should be noted that all the identified factors are very closely associated with each other, so it is necessary to evaluate them comprehensively in each patient with OSA.

Obstructive Sleep Apnea and a Comprehensive Remotely Supervised Rehabilitation Program: Protocol for a Randomized Controlled Trial

BACKGROUND

Obstructive sleep apnea (OSA) is characterized by recurrent, intermittent partial or complete obstruction of the upper respiratory tract during sleep, which negatively affects the patient's daily quality of life (QoL). Middle-aged and older men who smoke and have obesity are most at risk. Even though the use of continuous positive airway pressure (CPAP) during sleep remains the gold standard treatment, various rehabilitation methods, such as exercise, respiratory therapy, myofunctional therapy, and nutritional lifestyle interventions, also appear to be effective. Moreover, it is increasingly recommended to use alternative or additional therapy options in combination with CPAP therapy.

OBJECTIVE

This study aims to evaluate if a comprehensive home-based, remotely supervised rehabilitation program (tele-RHB), in combination with standard therapy, can improve OSA severity by decreasing the apnea-hypopnea index (AHI); improve objective parameters of polysomnographic, spirometric, anthropometric, and body composition examinations; improve lipid profile, maximal mouth pressure, and functional capacity tests; and enhance the subjective perception of QoL, as well as daytime sleepiness in male participants with moderate to severe OSA. Our hypothesis is that a combination of the tele-RHB program and CPAP therapy will be more effective by improving OSA severity and the abovementioned parameters.

METHODS

This randomized controlled trial aims to recruit 50 male participants between the ages of 30 and 60 years with newly diagnosed moderate to severe OSA. Participants will be randomized 1:1, either to a 12-week tele-RHB program along with CPAP therapy or to CPAP therapy alone. After the completion of the intervention, the participants will be invited to complete a 1-year follow-up. The primary outcomes will be the polysomnographic value of AHI, Epworth Sleepiness Scale score, 36-Item Short Form Health Survey (SF-36) score, percentage of body fat, 6-minute walk test distance covered, as well as maximal inspiratory and expiratory mouth pressure values. Secondary outcomes will include polysomnographic values of oxygen desaturation index, supine AHI, total sleep time, average heart rate, mean oxygen saturation, and the percentage of time with oxygen saturation below 90%; anthropometric measurements of neck, waist, and hip circumference; BMI values; forced vital capacity; forced expiratory volume in 1 second; World Health Organization's tool to measure QoL (WHOQOL-BREF) score; and lipid profile values.

RESULTS

Study recruitment began on October 25, 2021, and the estimated study completion date is December 2024. Analyses will be performed to examine whether the combination of the tele-RHB program and CPAP therapy will be more effective in the reduction of OSA severity and improvement of QoL, body composition and circumferences, exercise tolerance, lipid profile, as well as respiratory muscle and lung function, compared to CPAP therapy alone.

CONCLUSIONS

The study will evaluate the effect of a comprehensive tele-RHB program on selected parameters mentioned above in male participants. The results of this intervention could help the further development of novel additional therapeutic home-based options for OSA.

The role of telehealth in pediatric emergency care

In 2006, the Institute of Medicine published a report titled "Emergency Care for Children: Growing Pains," in which it described pediatric emergency care as uneven at best. Since then, telehealth has emerged as one of the great equalizers in care of children, particularly for those in rural and underresourced communities. Clinicians in these settings may lack pediatric-specific specialization or experience in caring for critically ill or injured children. Telehealth consultation can provide timely and safe management for many medical problems in children and can prevent many unnecessary and often long transport to a pediatric center while avoiding delays in care, especially for time-sensitive and acute interventions. Telehealth is an important component of pediatric readiness of hospitals and is a valuable tool in facilitating health care access in low resourced and critical access areas. This paper provides an overview of meaningful applications of telehealth programs in pediatric emergency medicine, discusses the impact of the COVID-19 pandemic on these services, and highlights challenges in setting up, adopting, and maintaining telehealth services.

Effectiveness of behavioral and psychosocial interventions for continuous positive airway pressure adherence among patients with obstructive sleep apnea: A systematic review and meta-analysis

BACKGROUND

Continuous positive airway pressure (CPAP) therapy is the treatment of choice for Obstructive Sleep Apnea (OSA) syndrome; however, interventions to improve CPAP adherence are still inconclusive.

OBJECTIVE

This study aimed to examine the effectiveness of behavioral and psychosocial interventions on CPAP adherence.

METHODS

The PRISMA guidelines and JBI approach for Systematic Review and Meta-analysis were used. Participants included 1) newly diagnosed patients with OSA, naive to CPAP treatment; 2) any type of behavioral and/or psychosocial intervention delivered via individual or group level; 3) CPAP adherence as an outcome. Two reviewers independently selected studies, evaluated their methodological quality, and extracted data.

RESULTS

Critical appraisal was conducted on 34 of the 1657 studies, with 18 RCTs included in the final review. Telemonitoring increased the mean nightly hour of CPAP use compared to standard care (WMD = 0.76, 95 % CI = 0.31-1.20, p = 0.001, I² = 0 %, moderate certainty of evidence). Positive results were discovered in Motivational Enhancement Therapy (MET) (WMD = 1.22, 95 % CI = 0.28-2.16, p = 0.011, I² = 65 %, very low degree of certainty of evidence). The combined effects of cognitive therapy and education on CPAP adherence were inconclusive. Behavioral/supportive interventions improved mean nightly CPAP use in both the short term (WMD = 1.49, 95 % CI = 0.16-2.81, p = 0.029, I² = 30 %, very low certainty of evidence) and long-term follow-up (WMD = 1.67, 95 % CI = 1.55-1.79, p = 0, I² = 0 %, very low certainty of evidence).

CONCLUSIONS

Telemonitoring improved the mean nightly hour of CPAP utilization compared with standard care. Motivational Enhancement Therapy (MET) had the most significant effect on long-term adherence.

Telemedicine compared to standard face-to-face care for CPAP treatment: real-world Australian experience

STUDY OBJECTIVES

We tested a telemedicine model of care to initiate continuous positive airway pressure (CPAP) for patients with obstructive sleep apnea (OSA) living in remote Western Australia.

METHODS

A prospective study comparing telemedicine for CPAP initiation in a remote population versus standard face-to-face CPAP initiation in a metropolitan population. The primary outcome was average nightly CPAP use in the final week of a CPAP trial.

RESULTS

A total of 186 participants were allocated to either telemedicine (n=56) or standard care (n=130). The average distance from the study centre for the telemedicine group was 979 km (±792km) compared to 19km (±14km) for the standard care group. The CPAP trial duration in the standard care group was less than the telemedicine group (37.6 vs 69.9 days, p<0.001). CPAP adherence in the telemedicine group was not inferior to standard care (Standard 4.7±0.2 hours, Telemedicine 4.7±0.3 hours, p=0.86). No differences were found between groups in residual apnea-hypopnea index, symptom response, sleep specific quality of life at the end of the trial and continued CPAP use (3 to 6 months). Participant satisfaction was high in both groups. Total health care costs of the telemedicine model were less than the standard model of care. An estimated A$4,538 per participant in travel costs was saved within the telemedicine group by reducing the need to travel to the sleep center for in-person management.

CONCLUSIONS

In remote dwelling adults starting CPAP for the treatment of OSA, outcomes using telemedicine were comparable to in-person management in a metropolitan setting.

[Obstructive Sleep Apnea]

Obstructive sleep apnea (OSA) is defined as the presence of an apnea-hyponea index (AHI)>15/h, predominantly obstructive or AHI greater than 5 with symptoms, the classic symptoms are observed apneas, daytime sleepiness and snoring, however, there are many other associated symptoms. To assess the severity of OSA, classically, only the AHI value was considered, but there is increasing evidence to implicate other factors. The predisposition to develop OSA is determined by anatomical and functional features. Having OSA increases the risk of accidents, high blood pressure (HBP) and is associated with cardiovascular risk, diabetes mellitus (DM), cardiac arrhythmia and neoplasms. To assess the probability of OSA, questionnaires and scales have been developed to assess symptoms, the certain diagnosis is obtained by polysomnography (PSG), which is the gold standard test, or polygraphy, which is a simpler and more accessible diagnostic test for diagnosis validated, the use of one or the other will depend on the suspicion and the associated comorbidities. Treatments for sleep apnea increasingly tend to be more individualized based on the characteristics of the patient and all are complementary. Hygienic-dietary measures should be applied in all patients, continuous positive airway pressure (CPAP) is the most effective treatment and with the most evidence, but other treatments are also available such as mandibular advancement devices (MAD), postural therapy and surgical options among others. Telemedicine is advancing in the follow-up of patients with OSA, both from non-face-to-face consultations and control of equipment via Wi-Fi to assess adherence, efficacy and correct control of therapy.

Adherence Monitoring Using Telemonitoring Techniques

Telemonitoring is a frequently used tool in the long-term management of many chronic diseases, such as chronic obstructive pulmonary disease or chronic heart failure. The use of new sensors and telemedical tools will shape medical practice in the future, particularly in sleep medicine. During the last decades, the number of people with sleep disordered breathing has been increasing.Telemedicine (TM) approaches could be used in various ways in sleep medicine: telediagnostics, teleconsultation, teletherapy, and telemonitoring of patients being treated with positive pressure devices.This chapter aims to summarize the recent scientific progresses of these techniques as well as their potential clinical applications and tries to give consideration to the remaining problems with TM applications.

Telemedicine in Sleep-Disordered Breathing: Expanding the Horizons

Interest in telemedicine has increased exponentially. There is a growing body of published evidence on the use of telemedicine for patients using continuous positive airway pressure. Telemedicine-ready devices can support the transmission on use time, apnea-hypopnea index, and leakage. This approach enables early activation of troubleshooting. Automated, personalized feedback for patients and patient access to their own data provide unprecedented opportunities for integrating comanagement approaches, multiactor interactions, and patient empowerment. Telemedicine is likely cost effective, but requires better evidence. Notwithstanding barriers for implementation that remain, telemedicine has to be embraced, leaving the physician and patient to accept it or not.

Video Consultation as an Adequate Alternative to Face-to-Face Consultation in Continuous Positive Airway Pressure Use for Newly Diagnosed Patients With Obstructive Sleep Apnea: Randomized Controlled Trial

Background

The effectiveness of continuous positive airway pressure (CPAP) is dependent on the degree of use, so adherence is essential. Cognitive components (eg, self-efficacy) and support during treatment have been found to be important in CPAP use. Video consultation may be useful to support patients during treatment. So far, video consultation has rarely been evaluated in thorough controlled research, with only a limited number of outcomes assessed.

Objective

The aim of the study was to evaluate the superiority of video consultation over face-to-face consultation for patients with obstructive sleep apnea (OSA) on CPAP use (minutes per night), adherence, self-efficacy, risk outcomes, outcome expectancies, expectations and experiences with video consultation, and satisfaction of patients and nurses.

Methods

A randomized controlled trial was conducted with an intervention (video consultation) and a usual care group (face-to-face consultation). Patients with confirmed OSA (apnea-hypopnea index >15), requiring CPAP treatment, no history of CPAP treatment, having access to a tablet or smartphone, and proficient in the Dutch language were recruited from a large teaching hospital. CPAP use was monitored remotely, with short-term (weeks 1 to 4) and long-term (week 4, week 12, and week 24) assessments. Questionnaires were completed at baseline and after 4 weeks on self-efficacy, risk perception, outcome expectancies (Self-Efficacy Measure for Sleep Apnea), expectations and experiences with video consultation (covering constructs of the unified theory of acceptance and use of technology), and satisfaction. Nurse satisfaction was evaluated using questionnaires.

Results

A total of 140 patients were randomized (1:1 allocation). The use of video consultation for OSA patients does not lead to superior results on CPAP use and adherence compared with face-to-face consultation. A significant difference in change over time was found between groups for short-term (P-interaction=.008) but not long-term (P-interaction=.68) CPAP use. CPAP use decreased in the long term (P=.008), but no significant difference was found between groups (P=.09). Change over time for adherence was not significantly different in the short term (P-interaction=.17) or long term (P-interaction=.51). A relation was found between CPAP use and self-efficacy (P=.001), regardless of the intervention arm (P=.25). No significant difference between groups was found for outcome expectancies (P=.64), self-efficacy (P=.41), and risk perception (P=.30). The experiences were positive, and 95% (60/63) intended to keep using video consultation. Patients in both groups rated the consultations on average with an 8.4. Overall, nurses (n=3) were satisfied with the video consultation system.

Conclusions

Support of OSA patients with video consultation does not lead to superior results on CPAP use and adherence compared with face-to-face consultation. The findings of this research suggest that self-efficacy is an important factor in improving CPAP use and that video consultation may be a feasible way to support patients starting CPAP. Future research should focus on blended care approaches in which self-efficacy receives greater emphasis.

Spanish Society of Pulmonology and Thoracic Surgery positioning on the use of telemedine in sleep-disordered breathing and mechanical ventilation

The rapid introduction of new information and communication technologies into medical practice has prompted Spanish Society of Pulmonology and Thoracic SurgeryR to publish a position paper on sleep-disordered breathing, especially in relation to positive pressure treatment. It should be pointed out that the scientific literature is to some extent controversial due to a paucity of large randomized multicenter studies with long-term follow-up. Moreover, the telematics devices and systems on the market vary widely. As a result, the recommendations are based primarily on a consensus of expert professionals. Another very important aspect addressed extensively in this document is the obvious lack of regulations on legal matters and the operations of commercial companies. The most important recommendations included in this position paper are that telemedicine is primarily advocated in subjects with travel problems or who live far from the hospital, in patients with poor CPAP compliance, and in most cases treated with non-invasive mechanical ventilation. A key element is patient individualization. It is imperative that the relevant technical, legal and ethical requirements (medical device regulations, data protection, and informed consent) are met. Finally, expert professionals from our society must contribute to and become involved in spearheading this technological change.

Telemedicine for Continuous Positive Airway Pressure in Sleep Apnea. A Randomized, Controlled Study

Rationale: Continuous positive airway pressure (CPAP) is the standard treatment for the obstructive sleep apnea syndrome (OSAS), but long-term adherence remains a challenge. In a pilot study, we observed that telemedicine combined with telemetrically triggered interventions was associated with improved CPAP adherence in the first month of treatment.Objectives: In the current randomized, controlled phase III trial, we aimed to collect pivotal data for the use of telemedicine in CPAP treatment of patients with OSAS.Methods: Symptomatic patients with OSAS were randomized to a telemedicine or control arm and initiated CPAP treatment. Phone calls were triggered in the telemedicine group during the first month of treatment upon either poor use or excessive mask leakage. Patients were followed for 6 months. Measures of CPAP use at 6 months were the main study endpoints.Results: Among 240 patients enrolled, 71 (30%) discontinued CPAP treatment over the course of the study. The primary outcome measure, the proportion of nights with CPAP use greater than 1 hour, was not statistically different in the telemedicine group (92.0%) versus the control group (88.2%) (P = 0.565). The daily hours of CPAP use at 6 months also did not differ significantly between the telemedicine group (5.6 h) and the control group (4.8 h) (P = 0.663). However, in a post hoc analysis, telemedicine led to increased device use in a subgroup of patients with a mild form of disease (5.6 h vs. 3.4 h; P = 0.026). The telemedicine-based intervention had a positive impact on sleep-related quality of life as measured with the Quebec Sleep Questionnaire (5.55 vs. 5.49 at 1 mo [P = 0.020]; 5.61 vs. 5.46 at 6 mo [P = 0.013]).Conclusions: A telemetrically triggered intervention in the first month of treatment did not improve CPAP use in the study population overall, but it had positive effects in patients with a mild form of OSAS and led to an improvement in sleep-related quality of life.Clinical trial registered with www.clinicaltrials.gov (NCT01715194).

Telehealth, Telemedicine, and Obstructive Sleep Apnea

Obstructive sleep apnea (OSA) telehealth management may improve initial and chronic care access, time to diagnosis and treatment, between-visit care, e-communications and e-education, workflows, costs, and therapy outcomes. OSA telehealth options may be used to replace or supplement none, some, or all steps in the evaluation, testing, treatments, and management of OSA. All telehealth steps must adhere to OSA guidelines. OSA telehealth may be adapted for continuous positive airway pressure (CPAP) and non-CPAP treatments. E-data collection enhances uses for individual and group analytics, phenotyping, testing and treatment selections, high-risk identification and targeted support, and comparative and multispecialty therapy studies.

Mobile health application to support CPAP therapy in obstructive sleep apnoea: design, feasibility and perspectives

Background

Current continuous positive airway pressure (CPAP) devices can be monitored remotely; however, in-person visits are kept for clinical follow-up in order to promote CPAP use and resolve potential side-effects. Mobile health is a promising way to provide remote and easy clinical control for CPAP follow-up and support. We aimed to evaluate the feasibility and acceptance by obstructive sleep apnoea (OSA) patients and healthcare professionals of a newly designed mobile app (Appnea-Q) to promote clinical control through a self-monitoring tool for patients with CPAP supervised by sleep professionals.

Methods

Appnea-Q incorporates a simple follow-up questionnaire with automated responses, together with frequent problems and lifestyle recommendations sections. Feasibility, acceptance and usefulness were assessed. First, an internal validation was performed during outpatient CPAP follow-up visits with sleep professionals from various sleep units. Second, an external validation was performed in a subgroup of 15 patients at home.

Results

Most patients (n=75) considered the app useful and were willing to use it and recommend it (72-88%). Up to 64.87% agreed on its capacity to reduce hospital visits. Appnea-Q was rated as acceptable (79.37±19.29) by the system usability score. Sleep professionals (n=30) concurred on its usefulness for OSA patient follow-up, particularly during the first month of CPAP therapy. The external validation showed its feasibility among 11 out of 15 patients and their data were received accordingly on the professionals' web platform.

Conclusions

According to our validation process, and the viewpoints of the patients and professionals, our new mobile app is a feasible and well-received tool for personal OSA management. Future clinical trials should substantiate its performance and cost-effectiveness in the clinical arena.

New organisation for follow-up and assessment of treatment efficacy in sleep apnoea

Obstructive sleep apnoea (OSA) is a highly prevalent disease, and there is an increased demand for OSA diagnosis and treatment. However, resources are limited compared with the growing needs for OSA diagnosis and management, and alternative strategies need to be developed to optimise the OSA clinical pathway. In this review, we propose a management strategy for OSA, and in general for sleep-disordered breathing, to be implemented from diagnosis to follow-up. For this purpose, the best current options seem to be: 1) networking at different levels of care, from primary physicians to specialised sleep laboratories; and 2) use of telemedicine. Telemedicine can contribute to the improved cost-effectiveness of OSA management during both the diagnostic and therapeutic phases. However, although the technology is already in place and different commercial platforms are in use, it is still unclear how to use telemedicine effectively in the sleep field. Application of telemedicine for titration of positive airway pressure treatment, follow-up to improve compliance to treatment through early identification and solution of problems, and teleconsultation all appear to be promising areas for improved OSA management.

Telemedicine could improve the management of sleep apnoea and other breathing disorders during sleep.http://bit.ly/2XPoPW1

Telemedicine in the diagnosis and treatment of sleep apnoea

Telemedicine (TM) is a current tool in the landscape of medicine. It helps to address public health challenges such as increases in chronic disease in an ageing society and the associated burden in healthcare costs. Sleep TM refers to patient data exchange with the purpose of enhancing disease management. Obstructive sleep apnoea (OSA) syndrome is a chronic disorder associated with a significant morbidity, mainly cardiometabolic, and mortality. Obtaining adequate compliance to continuous positive airway pressure (CPAP) remains the greatest challenge related to OSA treatment, and the adoption of TM to support OSA management makes sense. In addition, the prevalence of OSA is growing and OSA is associated with increased healthcare costs that could be streamlined by the application of TM. In OSA, multiple modalities of TM are utilised, such as telediagnostics, teleconsultation, teletherapy and telemonitoring of patients being treated with CPAP. In the present article, I aim to provide an overview of current practice and the recent developments in TM for OSA management. Concerns related to TM use will also be addressed.

Women's Attitudes Toward Self-Monitoring of Their Pregnancy Using Noninvasive Electronic Devices: Cross-Sectional Multicenter Study

Background

Pregnancy can be distressing, particularly if expectant mothers are worried about the well-being of their fetus. Consequently, the desire for reassurance and frequent fetal monitoring is often pronounced. Smart wearable devices and telemedicine are promising tools that could assist women in self-monitoring their pregnancy at home, hence disburdening emergency departments (EDs). They present the possibility to clarify the need for urgent care remotely and offer tighter pregnancy monitoring. However, patients’ acceptance of such new technologies for fetal monitoring has not yet been explored extensively.

Objective

This survey aimed to elucidate the attitudes of women toward self-monitoring of their pregnancy using noninvasive electronic devices. The technical details of the proposed devices were not specified.

Methods

A cross-sectional multicenter study was conducted at the departments of obstetrics of the University Hospitals of Heidelberg and Leipzig, Germany. All patients seen in the obstetrics clinic who were above 18 years were offered participation. We designed a survey questionnaire including validated instruments covering population characteristics, issues in current and past pregnancies, as well as attitudes toward self-monitoring of pregnancy with smart devices.

Results

A total of 509 pregnant women with no previous experience in telemedicine participated. Only a small minority of 5.9% (29/493) regarded self-monitoring with wearable devices as an alternative to consulting their physicians. Along these lines, only 7.7% (38/496) strongly believed they would visit the ED less often if such devices were readily available. However, if the procedure were combined with a Web-based telemetric physician consult, 13.5% (66/487) would be highly motivated to use the devices. Furthermore, significantly more women regarded it as an alternative prior to seeing a doctor when they perceived a decline in fetal movements (P<.001). Interestingly, women with university degrees had a higher propensity to engage in pregnancy self-monitoring compared with women without one (37% vs 23%; P=.001). Of the participants, 77.9% (381/489) would like smart wearable devices to measure fetal heart sounds, and 62.6% (306/489) wished to use the devices on their own. Feedback from a doctor or midwife was also very important in their choice of such devices (61.8%, 301/487 wished feedback). The intended frequency of use differed vastly among women, ranging from 13.8% (65/471) who would like to use such a device several times per day to 31.6% (149/471) who favored once per week at most.

Conclusions

Our results point to a skeptical attitude toward pregnancy self-monitoring among pregnant women. Nevertheless, many women are open to using devices for pregnancy monitoring in parallel to consulting their physician. The intention to use such devices several times daily or weekly, expressed by more than half of the participants, highlights the potential of such technologies.

Cost-effectiveness strategies in OSAS management: a short review

Obstructive sleep apnoea (OSAS) is an underdiagnosed chronic disease with a high prevalence in adults. It is becoming a significant social problem, since it is associated with a worsening in quality of life and increase in mortality. The cost-effectiveness ratio of diagnostic and therapeutic management of OSAS is a strategic issue to counteract the expected increasing demand of objective testing. OSAS patients with any clinical evidence of comorbidities must be studied using simplified and less expensive systems such as Home Sleep Testing (HST). On the other hand, Sleep Laboratory Polysomnography (PSG) is the gold standard to manage OSAS patients with comorbidities. It should be pointed out that the use of HST can lead to incorrect diagnosis in poorly selected OSAS subjects. This short review discusses various topics for the proper diagnosis and treatment of OSAS in view of epidemiological factors and results in terms of costs and social benefit of the disease. Whatever the strategy chosen and/or the organisational model adopted for managing OSAS, it cannot and should not take into account only cost-effectiveness. Long-term prospective studies evaluating cost-effectiveness ratios and outcomes of OSAS treatment of hospital management models versus home care models are needed.

Challenges and perspectives in obstructive sleep apnoea

Obstructive sleep apnoea (OSA) is a major challenge for physicians and healthcare systems throughout the world. The high prevalence and the impact on daily life of OSA oblige clinicians to offer effective and acceptable treatment options. However, recent evidence has raised questions about the benefits of positive airway pressure therapy in ameliorating comorbidities.

An international expert group considered the current state of knowledge based on the most relevant publications in the previous 5 years, discussed the current challenges in the field, and proposed topics for future research on epidemiology, phenotyping, underlying mechanisms, prognostic implications and optimal treatment of patients with OSA.

The group concluded that a revision to the diagnostic criteria for OSA is required to include factors that reflect different clinical and pathophysiological phenotypes and relevant comorbidities (e.g.nondipping nocturnal blood pressure). Furthermore, current severity thresholds require revision to reflect factors such as the disparity in the apnoea–hypopnoea index (AHI) between polysomnography and sleep studies that do not include sleep stage measurements, in addition to the poor correlation between AHI and daytime symptoms such as sleepiness. Management decisions should be linked to the underlying phenotype and consider outcomes beyond AHI.

Remote consulting with telemonitoring of continuous positive airway pressure usage data for the routine review of people with obstructive sleep apnoea hypopnoea syndrome: A systematic review

INTRODUCTION

Telehealth has the potential to offer more convenient care and reduce travel. We aimed to systematically review studies that assessed the effectiveness of teleconsultation plus telemonitoring in the review of people with obstructive sleep apnoea hypopnoea syndrome receiving continuous positive airway pressure therapy versus face-to-face care.

METHODS

Following Cochrane methodology, we searched 10 electronic databases (November 2015), trial registries, and reference lists of included studies, for trials testing interventions that combined remote consultations with telemonitoring of usage/continuous positive airway pressure data. Outcomes measures were: proportion reviewed, continuous positive airway pressure adherence, symptom control, and satisfaction/acceptability and cost effectiveness.

RESULTS

From 362 potentially relevant papers, we identified five randomised controlled trials ( n = 269 patients): four from North America and one from Spain. Risk of bias was moderate in one, and moderate/high in four trials. Two trials reported number/duration of reviews with inconsistent results. The teleconsultation/telemonitoring improved continuous positive airway pressure adherence in two trials ( n = 19; n = 75); two ( n = 114 and n = 75) reported no between-groups differences. Two studies, both at moderate/high risk of bias, showed no between-group difference in the Epworth Sleepiness Score. Satisfaction was generally reported positively in all five trials; one trial reported that the teleconsultation/telemonitoring patients were 'more likely to continue' with continuous positive airway pressure therapy treatment. One study reported teleconsultation/telemonitoring as cost effective.

DISCUSSION

The evidence for teleconsultation/telemonitoring in continuous positive airway pressure users is limited; however, no safety concerns have been raised. Adequately powered, well-designed trials are needed to establish whether real-time telemonitoring and remote teleconsultation is a clinically and cost effective option for people using continuous positive airway pressure therapy.

Technical Developments and Clinical Use of Telemedicine in Sleep Medicine

The use of assistive technology and telemedicine is likely to continue to shape our medical practice in the future, notably in the field of sleep medicine, especially within developed countries. Currently, the number of people suffering from obstructive sleep apnea syndrome (OSAS) is increasing. Telemedicine (TM) can be used in a variety of ways in sleep medicine: telediagnostics, teleconsultation, teletherapy and telemonitoring of patients being treated with positive pressure devices. In this review, we aim to summarize the recent scientific progresses of these techniques and their potential clinical applications and give consideration to the remaining problems related to TM application.

Tele-monitoring of ventilator-dependent patients: a European Respiratory Society Statement

The estimated prevalence of ventilator-dependent individuals in Europe is 6.6 per 100 000 people. The increasing number and costs of these complex patients make present health organisations largely insufficient to face their needs. As a consequence, their burden lays mostly over families. The need to reduce healthcare costs and to increase safety has prompted the development of tele-monitoring for home ventilatory assistance.

A European Respiratory Society Task Force produced a literature research based statement on commonly accepted clinical criteria for indications, follow-up, equipment, facilities, legal and economic issues of tele-monitoring of these patients.

Many remote health monitoring systems are available, ensuring safety, feasibility, effectiveness, sustainability and flexibility to face different patients' needs. The legal problems associated with tele-monitoring are still controversial. National and European Union (EU) governments should develop guidelines and ethical, legal, regulatory, technical, administrative standards for remote medicine. The economic advantages, if any, of this new approach must be compared to a “gold standard” of home care that is very variable among different European countries and within each European country.

Much more research is needed before considering tele-monitoring a real improvement in the management of these patients.

Sleep Telemedicine: An Emerging Field's Latest Frontier

There is a widening gap between sleep provider access and patient demand for it. An American Academy of Sleep Medicine position paper recently recognized sleep telemedicine as one tool to narrow that divide. We define the term sleep telemedicine as the use of sleep-related medical information exchanged from one site to another via electronic communications to improve a patient's health. Applicable data transfer methods include telephone, video, smartphone applications, and the Internet. Their usefulness for the treatment of insomnia and sleep-disordered breathing is highlighted. Sleep telemedicine programs range in complexity from telephone-based patient feedback systems to comprehensive treatment pathways incorporating real-time video, telephone, and the Internet. While large, randomized trials are lacking, smaller studies comparing telemedicine with in-person care suggest noninferiority in terms of patient satisfaction, adherence to treatment, and symptomatic improvement. Sleep telemedicine is feasible from a technological and quality-driven perspective, but cost uncertainties, complex reimbursement structures, and variable licensing rules remain significant challenges to its feasibility on a larger scale. As legislative reform pends, larger randomized trials are needed to elucidate impact on patient outcomes, cost, and health-care system accessibility.

Telemedicine Applications for the Pediatric Emergency Medicine: A Review of the Current Literature

OBJECTIVE

The aim of this study was to review current literature relating to telemedicine in pediatric emergency medicine including its clinical applications and challenges associated with its implementation.

METHODS

We reviewed the literature using standard search methods in accordance with preferred reporting items for systematic reviews and meta-analysis. We included the studies done in emergency settings for all age groups and narrowed our search to the articles that are relevant to "impact on quality of care" and "patient outcome." We also described current telemedicine uses, software, hardware, and other requirements needed for pediatric emergency applications.

RESULTS

Telemedicine has a potential role in pediatric emergency medicine for real-time decision making to improve quality of care for children. Logistic and legal challenges exist for pediatric emergency medicine applications similar to its uses in other settings.

CONCLUSIONS

Current frameworks exist in the use of telemedicine for pediatric emergency medicine. Research is still needed to see whether clinical outcomes are improved with pediatric emergency telemedicine solutions. Practical issues regarding training, accessibility, and resource allocation should be explored as pediatric emergency telemedicine evolves.

A Bayesian cost-effectiveness analysis of a telemedicine-based strategy for the management of sleep apnoea: a multicentre randomised controlled trial

BACKGROUND

Compliance with continuous positive airway pressure (CPAP) therapy is essential in patients with obstructive sleep apnoea (OSA), but adequate control is not always possible. This is clinically important because CPAP can reverse the morbidity and mortality associated with OSA. Telemedicine, with support provided via a web platform and video conferences, could represent a cost-effective alternative to standard care management.

AIM

To assess the telemedicine impact on treatment compliance, cost-effectiveness and improvement in quality of life (QoL) when compared with traditional face-to-face follow-up.

METHODS

A randomised controlled trial was performed to compare a telemedicine-based CPAP follow-up strategy with standard face-to-face management. Consecutive OSA patients requiring CPAP treatment, with sufficient internet skills and who agreed to participate, were enrolled. They were followed-up at 1, 3 and 6 months and answered surveys about sleep, CPAP side effects and lifestyle. We compared CPAP compliance, cost-effectiveness and QoL between the beginning and the end of the study. A Bayesian cost-effectiveness analysis with non-informative priors was performed.

RESULTS

We randomised 139 patients. At 6 months, we found similar levels of CPAP compliance, and improved daytime sleepiness, QoL, side effects and degree of satisfaction in both groups. Despite requiring more visits, the telemedicine group was more cost-effective: costs were lower and differences in effectiveness were not relevant.

CONCLUSIONS

A telemedicine-based strategy for the follow-up of CPAP treatment in patients with OSA was as effective as standard hospital-based care in terms of CPAP compliance and symptom improvement, with comparable side effects and satisfaction rates. The telemedicine-based strategy had lower total costs due to savings on transport and less lost productivity (indirect costs).

The role of pulmonology in the National Health System Chronicity Strategy

Longer life expectancy and the progressive aging of the population is changing the epidemiological pattern of healthcare, with a reduction in the incidence of acute diseases and a marked increase in chronic diseases. This change brings important social, healthcare and economic consequences that call for a reorganization of patient care. In this respect, the Spanish National Health System has developed a Chronicity strategy that proposes a substantial change in focus from traditional rescue medicine to patient- and environment-centered care, with a planned, proactive, participative and multidisciplinary approach. Some of the more common chronic diseases are respiratory. In COPD, this integrated approach has been effective in reducing exacerbations, improving quality of life, and even reducing costs. However, the wide variety of management strategies, not only in COPD but also in asthma and other respiratory diseases, makes it difficult to draw definitive conclusions. Pulmonologists can and must participate in the new chronicity models and contribute their knowledge, experience, innovation, research, and special expertise to the development of these new paradigms.
