Improving CPAP Adherence in Adults With Obstructive Sleep Apnea Syndrome: A Scoping Review of Motivational Interventions

The impact of PAP therapy first impression on short-term treatment adherence

PURPOSE

Positive airway pressure (PAP) treatment for obstructive sleep apnea syndrome (OSAS) is often burdened by lower adherence rates. Patients' perception and acceptance of PAP therapy play a crucial role in achieving acceptable adherence.

METHOD

We conducted a prospective cohort study to assess patients' initial impressions of PAP therapy using a six-item questionnaire. The questionnaire evaluated CPAP tolerance, interface comfort, titration pressure, likelihood of CPAP use, expected health benefits, and overall attitude toward PAP therapy. Patients underwent a baseline awake PAP therapy trial (T0) followed by titration with an automatic device (APAP). After one month of titration, a fixed CPAP value was set (T1). Follow-ups occurred at 1 (T2), 3 (T3), and 6 (T4) months after the start of treatment. Adherence to PAP therapy was considered sufficient if the mean device usage was ≥ 4 h/night at T4.

RESULTS

After six months, 77% of the enrolled patients achieved high PAP treatment adherence. Questionnaire scores generally improved from T0 to T4, particularly in CPAP tolerance, likelihood of treatment adherence, expected health benefits, and overall judgment of PAP therapy. Time-to-event analysis revealed that higher baseline scores in titration pressure comfort, likelihood of CPAP adherence, and overall judgment of PAP therapy were significantly associated with higher adherence likelihood.

CONCLUSION

Patients' first judgement on PAP therapy could significantly influence short-term adherence. Early identification and management of patients' complaints and discomforts could improve adherence rates and PAP perception over time.

Retinal microvascular phenotypes can track small vessel disease burden and CPAP treatment effectiveness in obstructive sleep apnea

Optical coherence tomography angiography (OCT-A) retinal imaging enables in vivo visualization of the retinal microvasculature that is developmentally related to the brain and can offer insight on cerebrovascular health. We investigated retinal phenotypes and neuroimaging markers of small vessel disease (SVD) in individuals with obstructive sleep apnoea (OSA). We enrolled 44 participants (mean age 50.1 ± SD 9.1 years) and performed OCT-A imaging before and after continuous positive airway pressure (CPAP) therapy. Pre-treatment analyses using a generalized estimating equations model adjusted for relevant covariates, revealed perivascular spaces (PVS) volume in basal ganglia associated with greater foveal vessel density (fVD) (p-value < 0.001), and smaller foveal avascular zone area (p-value = 0.01), whereas PVS count in centrum semiovale associated with lower retinal vessel radius (p-value = 0.02) and higher vessel tortuosity (p-value = 0.01). A reduction in retinal vessel radius was also observed with increased OSA severity (p-value = 0.05). Post-treatment analyses showed greater CPAP usage was associated with a decrease in fVD (p-value = 0.02), and increased retinal vessel radius (p-value = 0.01). The findings demonstrate for the first time the potential use of OCT-A to monitor CPAP treatment and its possible impact on both retinal and brain vascular health.

A mixed-methods pilot study of domiciliary nasal high-flow therapy for breathlessness in people with chronic obstructive pulmonary disease who do not qualify for domiciliary long-term oxygen therapy

BACKGROUND

High-flow nasal oxygen (HFNO) therapy delivers humidified, heated air with flow rates of up to 60 L/min with oxygen entrained. HFNO has advantages over conventional oxygen therapy, including precise and reliable fraction of inspired oxygen delivery, therefore is recommended as first-line treatment for people with acute hypoxaemic respiratory failure.

OBJECTIVES

This pilot study aimed to determine the feasibility and acceptability of domiciliary nasal high flow (NHF) without entrained oxygen for people with chronic obstructive pulmonary disease (COPD) and severe breathlessness.

DESIGN

Single-arm, mixed-methods, pilot study of an 8-day, air-only NHF intervention in adults with COPD and severe breathlessness not requiring domiciliary oxygen therapy.

METHODS

Participants were educated and advised to use NHF for ⩾7 h per night for 7 nights with day use as desired. Patient-reported outcome measures were assessed on Days 3, 5 and 8.

PRIMARY OUTCOME

feasibility.

SECONDARY OUTCOMES

breathlessness (dyspnoea), fatigue, quality of life, physical function, sleep, tolerability and safety. Acceptability was also assessed through semi-structured interviews.

RESULTS

Fifteen participants were enrolled (mean age 73.6; 40% women; mean FEV1 41% predicted, mean DLCO 43.0% predicted; mean modified Medical Research Council score 3.7). Thirteen (87%) completed the trial, with 8 (54%) keeping the device at the end of the trial and 3 (20%) continuing use long-term. Adherence varied, with average daily usage higher amongst participants who kept the device compared to those who returned it (6.8 h ± 2.3 h vs 3.4 h ± 3.7 h). No changes in worst breathlessness (mean = 0.7, SD = 1.2, p = 0.109), dyspnoea mastery (mean = 0.3, SD = 0.6, p = 0.176) or fatigue (mean = 0.0, SD = 2.4, p = 1.00) were observed at Day 8 compared to baseline. No significant adverse events were reported. Qualitative interviews demonstrated subjective improvements in breathlessness, dry mouth and sputum production for some participants, whilst others found NHF uncomfortable. Fear of NHF dependence and concerns regarding long-term running costs were reported.

CONCLUSION

Domiciliary NHF was a feasible intervention, albeit with varied adoption and acceptability. These trial implementation outcomes may have affected preliminary effectiveness outcomes. Further research is required to determine what role domiciliary NHF may have for people with COPD and severe breathlessness.

Real world challenges and barriers for positive airway therapy use in acute ischemic stroke patients

PURPOSE

Untreated obstructive sleep apnea (OSA) in patients with acute ischemic stroke (AIS) is associated with increased morbidity and mortality. However, diagnosing and treating OSA in AIS is challenging. We aimed to determine the feasibility of portable monitoring (PM) for diagnosis and positive airway pressure therapy for treatment of OSA in an inpatient stroke population.

METHODS

We recruited inpatients with AIS from Cleveland Clinic. Those who consented underwent PM; participants with a respiratory event index (REI) ≥ 10 were offered auto-titrating positive airway pressure therapy (APAP). Ease-of-use questionnaires were completed. We summarized categorical variables using n(%) and continuous variables using mean ± SD or median [IQR].

RESULTS

27 participants (age 59.8 ± 11.8, 51.9% female, 51.9% Black, BMI 33.4 ± 8.5) enrolled. The study ended early due to Medicare contracting that forced most patients to complete stroke rehabilitation outside the Cleveland Clinic health system. 59.3% had large vessel occlusions and 53.8% had moderate/severe disability (Modified Rankin score ≥ 2). PM was attempted in 21 participants, successful in 18. Nurses and patients rated the PM device as highly easy to use. 13 of 18 (72%) patients who had an REI ≥ 10 consented to APAP titration, but only eight (61.5%) of those 13 used APAP for more than one night, and only five (27.8%) used APAP up to 90 days with data captured for only one participant. Five required troubleshooting at titration, and only one had adherent APAP usage by objective assessment after discharge.

CONCLUSIONS

This study demonstrates the real-world challenges of assessing and treating OSA in an AIS population, highlighting the necessity for further research into timely and feasible screening and treatment.

Remote monitoring system to support positive airway pressure therapy in patients with obstructive sleep apnea: a multi-center randomized controlled trial

PURPOSE

To develop and evaluate an intervention tailored to patients' needs to increase the rate of positive airway pressure (PAP) adherence in patients afflicted with obstructive sleep apnea (OSA), who undergo PAP therapy.

METHODS

A multi-center, 3 parallel-arm, randomized, controlled trial was conducted. Participants with OSA who undergo a PAP therapy were randomized to one of three groups: control arm (usual care), educational booklet arm, and mobile-based application arm. PAP usage, the percentage of days using the device for more than 4 h, change in knowledge, risk perception, outcome expectancy, self-efficacy, and ESS were assessed before and one month after interventions in the three groups. Also, the application usage data were analyzed.

RESULTS

The result showed the change in average PAP usage, knowledge, risk perception, and self-efficacy in the application group was significantly higher than the control and booklet groups. Also, the change in use for more than 4 h in the application group was significantly higher than the control group. Comparing the actual and patients' self-report PAP use indicated patients' self-report about the use of the device is about 50 min (0.8 h) more than the actual amount of use.

CONCLUSION

The study results indicated that the improvement of primary and secondary outcomes in adherence to PAP was significantly higher in the application group than in other study groups. Given the increasingly penetrating influence of smartphone-based technologies, it seems that mobile-based applications could potentially be adopted in the population of patients with OSA.

Educational video demonstrating collapsibility of the upper airway during sleep improves initial acceptance of CPAP in patients with severe obstructive sleep apnea: a retrospective study

STUDY OBJECTIVES

We investigated whether an audiovisual educational video demonstrating collapsibility of the upper airway during sleep would influence initial continuous positive airway pressure (CPAP) acceptance among patients with severe obstructive sleep apnea.

METHODS

Between January 2017 and December 2018, a single-center retrospective study was conducted. We implemented an educational video demonstrating upper airway collapsibility during sleep in February 2018. We analyzed the medical records from 145 consecutive patients diagnosed with severe obstructive sleep apnea who underwent in-laboratory polysomnography both before and after implementing the educational video. Among them, 76 patients received standard care before the video's introduction (standard care group), and another 69 patients were managed after its implementation (video group).

RESULTS

Baseline characteristics including age, body mass index, educational level, occupation category, comorbidities, Mallampati score, Epworth Sleepiness Scale score, apnea-hypopnea index, and sleep time with SpO2 below 90% were not significantly different between the 2 groups. Acceptance of CPAP following an in-laboratory overnight titration study was significantly higher in the video group (80%) than in the standard care group (57%) (P = .003). Multivariate regression analyses revealed that watching the video was a strong predictor of initial CPAP acceptance (odds ratio, 4.162; 95% confidence interval, 1.627-10.646; P = .004). Both sleep time with SpO2 below 90% (odds ratio, 1.020; 95% confidence interval, 1.002-1.038; P = .029) and sleep efficiency (odds ratio, 1.052; 95% confidence interval, 1.023-1.083; P < .001) were weak predictors for initial CPAP acceptance. At 12 months, adherence among those who accepted the CPAP treatment was similar between the 2 groups (78% vs 74%; P = .662). However, within the initial cohorts, a significantly higher proportion of patients in the video group (62%) were using CPAP at 12 months compared with the standard care group (42%) (P = .015).

CONCLUSIONS

Among patients with severe obstructive sleep apnea, an educational video demonstrating upper airway collapsibility during sleep improved initial CPAP acceptance rates when compared with standard care.

Adherence to CPAP Therapy in Obstructive Sleep Apnea: A Prospective Study on Quality of Life and Determinants of Use

Obstructive sleep apnea (OSA) often goes unrecognized despite common symptoms, such as excessive daytime sleepiness, fatigue, and impaired quality of life (QoL). Continuous positive airway pressure (CPAP) is the gold standard treatment for OSA, but optimal daily usage and time needed for observable effects remain unclear. This study aimed to investigate the short-term effects of CPAP on daytime sleepiness and QoL in patients with severe OSA. Medical records were collected from 87 patients with severe OSA who initiated CPAP therapy. Also, validated questionnaires were used before and after one month of CPAP to analyze QoL-the Calgary Sleep Apnea Quality of Life Index (SAQLI), the Cues to CPAP Use Questionnaire (CCUQ), and daytime sleepiness-the Epworth Sleepiness Scale (ESS). Multiple regression analysis was conducted to identify predictors of CPAP usage. Of the total participants aged 55.6 ± 12.5, 77% were males, and 62% were CPAP adherent. Reductions in daytime sleepiness (ESS) were noted, as well as improvements in both overall QoL (SAQLI) and specifically in the domains of daily functioning, social interactions, emotional well-being, and symptom perception. Important cues for CPAP usage recognized by patients were physicians' instructions and physicians' concern regarding their patients' condition. Furthermore, multiple regression revealed higher SAQLI scores and lower ESS scores as positive predictors of CPAP usage, along with lower AHI after one month of CPAP being associated with sufficient adherence.

Behavioral KSA Intervention Class to Boost Positive Airway Pressure Adherence Among Active Duty Military Personnel With Obstructive Sleep Apnea

INTRODUCTION

Obstructive sleep apnea (OSA) is a treatable cause of daytime sleepiness and associated medical problems that can negatively impact soldier readiness and performance. This study examined adherence to positive airway pressure (PAP) by soldiers who were newly diagnosed with OSA and prescribed PAP therapy and participated in a Knowledge, Skills, and Attitudes (KSA) behavioral intervention class.

MATERIALS AND METHODS

The KSA was a one-time, interactive 90-minute class attended by up to 10 patients per class. PAP adherence was examined using Medicare standard at 30-, 60-, 90-, and 180 days post class. The analytic sample comprised 379 active duty patients (93% men; mean age 40.21 ± 8.06) categorized into 3 groups: KSA (n = 235), did not show (DNS; n = 61), and mandatory education class (MEC; n = 83). The MEC group comprised patients from an education class in a previous year.

RESULTS

Baseline scores on the apnea hypopnea index, body mass index, sleepiness, insomnia severity, and age were non-significant among the 3 groups. At 30 days, significantly more patients in KSA (48%) and MEC (51%) were adherent than the DNS group (16%). At 60 days, the adherence rates for the KSA, DNS, and MEC were significantly different at 39%, 22%, and 27%, respectively. At 90- and 180 days, the adherence rates among the KSA, DNS, and MEC groups did not differ significantly at 34%, 17%, and 26% (90 days) and 34%, 27%, and 25% (180 days), respectively. Consistently, more patients in KSA were adherent than those in DNS and MEC, except at 30 days. Additionally, adherence rates for KSA intervention declined more gradually over the 6 month period. The mean PAP usage on nights used was 4.6 hours that computed to a 34% non-use rate based on an optimal 7-hour/night sleep time.

CONCLUSION

KSA could be a behavioral intervention that enhances PAP adherence with a booster session implemented at the 90 days mark.

The impact of obstructive sleep apnea treatment on microvascular complications in patients with type 2 diabetes: a feasibility randomized controlled trial

STUDY OBJECTIVES

Obstructive sleep apnea (OSA) is associated with an increased risk of diabetes-related complications. Hence, it is plausible that continuous positive airway pressure (CPAP) could have a favorable impact on these complications. We assessed the feasibility of conducting a randomized control trial in patients with type 2 diabetes and OSA over 2 years.

METHODS

We conducted an open-label multicenter feasibility randomized control trial of CPAP vs no CPAP in patients with type 2 diabetes and OSA. Patients with resting oxygen saturation < 90%, central apnea index > 15 events/h, or Epworth Sleepiness Scale ≥ 11 were excluded. OSA was diagnosed using a multichannel portable device (ApneaLink Air, ResMed). The primary outcome measures were related to feasibility and the secondary outcomes were changes in various clinical and biochemical parameters related to diabetes outcomes.

RESULTS

Eighty-three (40 CPAP vs 43 no CPAP) patients were randomly assigned, with a median (interquartile range) follow-up of 645 (545, 861) days. CPAP compliance was inadequate, with a median usage of approximately 3.5 hours/night. Early CPAP use predicted longer-term compliance. The adjusted analysis showed a possible favorable association between being randomly assigned to CPAP and several diabetes-related end points (chronic kidney disease, neuropathy, and quality of life).

CONCLUSIONS

It was feasible to recruit, randomly assign, and achieve a high follow-up rate over 2 years in patients with OSA and type 2 diabetes. CPAP compliance might improve by a run-in period before randomization. A full randomized control trial is necessary to assess the observed favorable association between CPAP and chronic kidney disease , neuropathy, and quality of life in patients with type 2 diabetes.

Sociological determinants of adherence to continuous positive airway pressure in the management of sleep apnoea syndrome: protocol for a transdisciplinary, prospective observational study

INTRODUCTION

Obstructive sleep apnoea syndrome (OSAS) is a chronic multiorgan pathology that has a negative impact on quality of life. Continuous positive airway pressure (CPAP) is the first-line treatment for OSAS. However, CPAP termination rates remain very high, and adherence to therapy is a major issue. To date, studies targeting predictive factors of CPAP adherence by OSAS patients mainly include clinical data. The social, socioeconomic, psychological, and home environment aspects have been far less studied and largely underestimated. This study aims to obtain solid quantitative results examining the relationship between the determinants of refusal, non-adherence, or termination of CPAP treatment, and in particular the pivotal role played by health literacy.

METHODS AND ANALYSIS

This is a prospective, multicentre, observational study recruiting patients attending the sleep clinic of the Grenoble Alpes University Hospital, France. Consecutive adults (>18 years) recently diagnosed with OSAS and prescribed CPAP treatment with telemonitoring will be enrolled in the present study. They will benefit from home visits by a CPAP technician or nurse at CPAP initiation. Patients will then be followed up for 6 months through the telemonitoring platform of a home-care provider. The primary objective is to evaluate the impact of health literacy (health literacy, measured by the European Health Literacy Survey questionnaire (HLS-EU-16) on the refusal, non-adherence or termination of CPAP treatment in newly diagnosed OSAS patients, during the first 6 months after diagnosis. The target sample size is 250 participants.

ETHICS AND DISSEMINATION

The study protocol, patient information, and the non-opposition form were approved by the French national ethics committee (CPP 2021-92, January 2022). All patients are required to have signed a written informed consent form permitting their anonymised personal and medical data to be used for clinical research purposes. We will publish the results in a peer-reviewed medical journal and on our institutional websites.

Pharmacotherapy for obstructive sleep apnea: targeting specific pathophysiological traits

INTRODUCTION

The pathophysiology of obstructive sleep apnea (OSA) is multi-factorial and complex. Varying OSA's pathophysiological traits have been identified, including pharyngeal collapsibility, upper airway muscle reactivity, arousal threshold, and regulation of the ventilatory drive. Being CPAP of difficult tolerance and other interventions reserved to specific subpopulations new pharmacological treatments for OSA might be resolutive.

AREAS COVERED

Several existing and newly developed pharmacological drugs can impact one or more endotypes and could therefore be proposed as treatment options for sleep disordered breathing. With this review we will explore different pathophysiological traits as new targets for OSA therapy. This review will summarize the most promising pharmacological treatment for OSA accordingly with their mechanisms of action on upper airway collapsibility, muscle responsiveness, arousal threshold, and loop gain.

EXPERT OPINION

Only understanding the pathophysiological traits causing OSA in each patient and placing the disease in the framework of patient comorbidities, we will be able to evolve interventions toward OSA. The development of new drug's combinations will permit different approaches and different choices beside conventional treatments. In the next future, we hope that sleep specialists will select the treatment for a specific patient on the base of its pathophysiology, defining a precision medicine for OSA.

The long wave of COVID-19: a case report using Imagery Rehearsal Therapy for COVID-19-related nightmares after admission to intensive care unit

Introduction

The COVID-19 pandemic caused several psychological consequences for the general population. In particular, long-term and persistent psychopathological detriments were observed in those who were infected by acute forms of the virus and need specialistic care in the Intensive Care Unit (ICU). Imagery rehearsal therapy (IRT) has shown promising results in managing nightmares of patients with different traumas, but it has never been used with patients admitted to ICUs for severe COVID-19 despite this experience being considered traumatic in the literature.

Methods

The purpose of this case study is to describe the application of a four-session IRT for the treatment of COVID-related nightmares in a female patient after admission to the ICU. A 42-year-old Caucasian woman who recovered from a pulmonary rehabilitation program reported shortness of breath, dyspnea, and everyday life difficulties triggered by the long-COVID syndrome. She showed COVID-related nightmares and signs of post-traumatic symptoms (i.e., hyperarousal, nightmares, and avoidance of triggers associated with the traumatic situation). Psychological changes in the aftermath of a trauma, presence, and intensity of daytime sleepiness, dream activity, sleep disturbances, aspects of sleep and dreams, and symptoms of common mental health status are assessed as outcomes at the baseline (during the admission to pneumology rehabilitation) at 1-month (T1) and 3-month follow-up (T2). Follow-up data were collected through an online survey.

Results

By using IRT principles and techniques, the patient reported a decrease in the intensity and frequency of bad nightmares, an increase in the quality of sleep, and post-traumatic growth, developing a positive post-discharge.

Conclusion

Imagery rehearsal therapy may be effective for COVID-19-related nightmares and in increasing the quality of sleep among patients admitted to the ICU for the treatment of COVID-19. Furthermore, IRT could be useful for its brevity in hospital settings.

Impact of reboxetine plus oxybutynin treatment for obstructive sleep apnea on cardiovascular autonomic modulation

The combination of noradrenergic (reboxetine) plus antimuscarinic (oxybutynin) drugs (reb-oxy) reduced obstructive sleep apnea (OSA) severity but no data are available on its effects on cardiac autonomic modulation. We sought to evaluate the impact of 1-week reb-oxy treatment on cardiovascular autonomic control in OSA patients. OSA patients were randomized to a double-blind, crossover trial comparing 4 mg reboxetine plus 5 mg oxybutynin to a placebo for OSA treatment. Heart rate (HR) variability (HRV), ambulatory blood pressure (BP) monitoring (ABPM) over 24 h baseline and after treatment were performed. Baroreflex sensitivity was tested over beat-to-beat BP recordings. 16 subjects with (median [interquartile range]) age 57 [51-61] years and body mass index 30 [26-36]kg/m² completed the study. The median nocturnal HR was 65 [60-69] bpm at baseline and increased to 69 [64-77] bpm on reb-oxy vs 66 [59-70] bpm on placebo (p = 0.02). The mean 24 h HR from ABPM was not different among treatment groups. Reb-oxy administration was not associated with any modification in HRV or BP. Reb-oxy increased the baroreflex sensitivity and did not induce orthostatic hypotension. In conclusion, administration of reb-oxy did not induce clinically relevant sympathetic overactivity over 1-week and, together with a reduction in OSA severity, it improved the baroreflex function.

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.

A Scoping Review of Sleep Apnea: Where Do We Stand?

Obstructive sleep apnea (OSA), a condition in which there is a recurrent collapse of the upper airway while sleeping, is a widespread disease affecting 5% to 10% people worldwide. Despite several advances in the treatment modalities for OSA, morbidity and mortality remain a concern. Common symptoms include loud snoring, gasping for air during sleep, morning headache, insomnia, hypersomnia, attention deficits, and irritability. Obese individuals, male gender, older age (65+), family history, smoking, and alcohol consumption are well recognized risk factors of OSA. This condition holds the ability to increase inflammatory cytokines, cause metabolic dysfunction, and increase the sympathetic output, all of which exacerbate OSA due to their effect on the cardiovascular system. In this review, we discuss its brief history, risk factors, complications, treatment modalities, and the role of clinicians in curbing its risk.

Adherence to CPAP Treatment: Can Mindfulness Play a Role?

Obstructive sleep apnea (OSA) is considered a chronic disease that requires long-term multidisciplinary management for effective treatment. Continuous Positive Airway Pressure (CPAP) is still considered the gold standard of therapy. However, CPAP effectiveness is limited due to poor patients' adherence, as almost 50% of patients discontinue treatment after a year. Several interventions have been used in order to increase CPAP adherence. Mindfulness-based therapies have been applied in other sleep disorders such as insomnia but little evidence exists for their application on OSA patients. This review aims to focus on the current data on whether mindfulness interventions may be used in order to increase CPAP adherence and improve the sleep quality of OSA patients. Even though controlled trials of mindfulness and CPAP compliance remain to be performed, this review supports the hypothesis that mindfulness may be used as an adjunct method in order to increase CPAP adherence in OSA patients.

Short-Term Benefits of Continuous Positive Airway Pressure Treatment on Cognition in the Obstructive Sleep Apnea Syndrome: A Retrospective Study

The Obstructive Sleep Apnea Syndrome (OSAS) significantly impacts cognitive functioning. The prolonged use (more than 3 months) of ventilotherapy with continuous positive airway pressure (CPAP) seems to have positive effects in restoring cognitive difficulties. However, there is poor evidence about its possible short-term effect. We investigated whether the short use (less than 15 days at testing) of CPAP improved the cognitive functioning in fifty individuals with OSAS by collecting retrospective neuropsychological measures about verbal memory and learning, information processing speed, attention (i.e., alerting, orienting, and executive system), and executive functions (i.e., strategic reasoning, problem-solving, and mental planning). The predictive role of days of CPAP use on the neuropsychological scores was assessed by hierarchical multiple linear regression analyses, over and above the possible role of demographics, body mass index, level of OSAS severity, and the level of anxiety and depression. The average number of days since CPAP adaptation was 4.70 (SD = 3.90; range = 0-15). As the days of CPAP adaptation increased, verbal learning and long-term memory significantly improved, contrary to the other assessed domains. Our results show a significant improvement in some cognitive functions even after a short treatment with CPAP, pointing to the importance of the early use of ventilotherapy to rapidly improve cognitive functioning. Identifying which cognitive functions can or cannot be restored with CPAP use may enable the design of complementary neuropsychological interventions focused on those residual difficulties, possibly enhancing patients' compliance to the treatment.

Pharmacotherapy for Obstructive Sleep Apnoea and Coupled Life: A Descriptive Phenomenological Study of a Complex Interaction

BACKGROUND

Obstructive Sleep Apnoea (OSA) is a common chronic sleep-related breathing disorder. Drug therapy is a recent approach to treating OSA, and no data is available regarding its effects on a couple's life. The aim of this study was to investigate the impact on couples' lives of a novel drug treatment for OSA.

METHODS

Participants of a trial on new drug therapy (reboxetine plus oxybutynin) for OSA were interviewed. The study was conducted using a descriptive phenomenological approach by Sundler et al. Results: Ten patients and six of their partners were recruited through a purposive sampling between February and April 2021. The results indicate that drug treatment of OSA had a favourable impact on the couples' lives. Pharmacotherapy improved self-reported sleep quality, as the absence of CPAP allows people to sleep closer to the bed partner and because the patient does not have to sleep in a forced position. Moreover, the couples developed teamwork from the beginning which appeared to be crucial during the trial, especially when some difficulties and adverse events occurred.

CONCLUSIONS

This study presents the presence of a positive closed loop that could be considered a predictor of adherence to drug therapy.

Patient-Centered Therapy for Obstructive Sleep Apnea: A Review

Obstructive sleep apnea (OSA) is one of the most common sleep problems defined by cessation or decreased airflow despite breathing efforts. It is known to be related to multiple adverse health consequences. Positive airway pressure (PAP) is considered an effective treatment that is widely used. Various modes of PAP and other emerging treatment options are now available. A multidisciplinary approach, understanding diverse phenotypes of OSA, and shared decision-making are necessary for successful OSA treatment. Patient-centered care is an essential modality to support patient care that can be utilized in patients with OSA to help improve outcomes, treatment adherence, and patient satisfaction.

Motivational Interviewing Effects on Positive Airway Pressure Therapy (PAP) Adherence: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

OBJECTIVES

This systematic review and meta-analysis examined Motivational Interviewing (MI) effects on positive airway pressure (PAP) adherence and related outcomes.

METHOD

Medline, CIHANL, Psych Info, Web of Science, PubMed, and Cochrane Database of Systematic Reviews were searched for randomized controlled trials published from peer-reviewed journals in English from 1990 to 2021 that compared objective PAP adherence among adults with obstructive sleep apnea (OSA) in a MI and non-MI intervention. A random effects meta-analysis model was completed at the 1-to-2-week, and 1-, 2-, 3-, and 12-month follow-up, and risk of bias was analyzed with the Cochrane Risk of Bias Tool.

RESULTS

In 10 trials of naïve PAP users and one trial of non-naïve PAP users, 14 to 277 middle-aged adults with moderate-to-severe OSA generally engaged in a brief, individual, face-to-face, MI intervention with standard care or a control condition. Several trials of naïve PAP users demonstrated that MI increased PAP use 1-2.6 hours per night, but a similar number of trials showed comparable conditions. Secondary outcomes were mixed. Among non-naïve PAP users, MI did not significantly increase adherence or secondary outcomes. The meta-analysis of PAP-naïve participants revealed that MI had a small to moderate significant effect on PAP adherence at 1, 2, and 3 months after beginning PAP (Hedges' g = 0.38 to 0.48; 95% CI = 0.04, 0.75) compared to standard care alone.

CONCLUSIONS

Despite heterogeneity, MI moderately increased PAP adherence among PAP-naïve adults with moderate-to-severe OSA, suggesting an effective strategy for short-term (1-3 months) adherence.

Study protocol of a randomized controlled trial of motivational interviewing-based intervention to improve adherence to continuous positive airway pressure in patients with obstructive sleep apnea syndrome: The MotivAir study

Objective

This study aims to evaluate the effectiveness of the MotivAir program-a phone-based intervention based on Motivational Interviewing (MI) principles and techniques-in enhancing adherence to Continuous Positive Airway Pressure (CPAP) therapy among patients with Obstructive Sleep Apnea Syndrome (OSAS).

Methods

A multicenter randomized controlled trial (RCT) design with random allocation at the level of the individual will be conducted to compare the impact of the experimental program (usual care plus MI) with a control group receiving usual care only in improving selected clinical and psychological parameters in the patients. A minimum sample of 80 participants (40 patients per group) will be recruited in each center according to the inclusion criteria. After the initial screening, participants will be randomly assigned to either the experimental group or the control condition. The program will last 180 days and will be delivered by a trained nurse. The impact of the MotivAir program on selected primary (adherence to CPAP in terms of average hours of usage per night and the Apnea-Hypopnea Index, AHI) and secondary (motivation, perceived competence, quality of life, sleepiness) outcomes will be measured at baseline, and after 1-, 3-, and 6-month from CPAP initiation.

Discussion

Participants are expected to show an increased level of adherence to CPAP and to acquire the skills and self-confidence necessary to deal with the psychological consequences of their chronic condition.

Obstructive Sleep Apnea and Adherence to Continuous Positive Airway Pressure (CPAP) Treatment: Let's Talk about Partners!

BACKGROUND

Continuous positive airway pressure (CPAP) is the gold standard treatment for obstructive sleep apnea (OSA). The benefits of this therapy were studied and analyzed over time; patient adherence is often poor, as many factors negatively influence it. A topic that needs clarification is whether adherence to CPAP treatment in a patient with OSA is influenced by the behavior of a partner or spouse.

METHODS

A scoping review was conducted to evaluate the role of partner involvement in the CPAP treatment management in a patient with OSA. The research project was performed between August and September 2021 by consulting the main biomedical databases: CINHAL, Embase, PsycINFO, and PubMed.

RESULTS

Among 21 articles considered valid for our aim, 15 are qualitative studies, 5 are quantitative and 1 presents a mixed method. We identified several thematic areas and "key" elements, which are prevalent in the studies evaluated.

CONCLUSIONS

The presence of a partner promotes adherence to CPAP therapy in patients with OSA, resulting in ameliorating their overall quality of life. To increase CPAP adherence, a trained nurse could represent a reference figure to technically and emotionally support couples during the adaptation period and in the long term.

Precision Medicine in Adult Obstructive Sleep Apnea and Home Diagnostic Testing: Caution in Interpretation of Home Studies Without Clinician Input Is Necessary

Purpose

To assess the validity of home sleep apnea test directed diagnosis and treatment of obstructive sleep apnea (OSA) in a real-life clinical setting and establish the extent to which clinical evaluation alters diagnosis and therapeutic intervention, in the context of the evolving realm of precision medicine.

Methods

Retrospective consecutive cohort study of 505 patients referred to a single center between 15th September 2015 to 14th September 2016, multidisciplinary specialist sleep clinic presenting with a home sleep apnea test prior to referral. We evaluated the effect of sleep medicine practitioner (SMP) and ear, nose, and throat surgeon (ENTS) review on patient diagnoses, disease severity, and management options in OSA.

Results

Hundred and fifteen patients were included. Repeat evaluation with in-lab polysomnogram (PSG) was required in 46/115 (40.0%) of patients, of which 20/46 (43.5%) had OSA severity changed. Sleep medicine practitioner review decreased the need for repeat testing with formal in-lab PSG (p < 0.05) and increased patient acceptance of continuous positive airway pressure (CPAP) as a long-term management option for OSA. Sleep medicine practitioner/ENTS review resulted in discovery of a non-OSA related sleep disorder or change in OSA severity in 47.8% (55/115). Ear, nose, and throat surgeon review resulted in additional or changed diagnosis in 75.7% (87/115) of patients.

Conclusion

In the clinical assessment and diagnosis of OSA, patients should be reviewed by medical practitioners with an interest in sleep disorders to better navigate the complexities of assessment, as well as the identification of co-morbid conditions.

Assessing the needs and perspectives of patients with obesity and obstructive sleep apnea syndrome following continuous positive airway pressure therapy to inform health care practice: A focus group study

Objective

This study aims to investigate the lived experience in patients with obstructive sleep apnea syndrome (OSAS) and comorbid obesity following after continuous positive airway pressure (CPAP) therapy made with the disease the device, and to identify barriers and facilitators to the use of CPAP to improve rehabilitation provision and aid in disease self-management.

Methods

Qualitative research was conducted using three focus groups with a representative sample of 32 inpatients (37% female) undergoing a 1-month pulmonary rehabilitation program at the IRCSS Istituto Auxologico Italiano San Giuseppe Hospital, Verbania, Italy. The focus groups were recorded on tape, and contemporaneous notes were made. The tapes were transcribed verbatim, and Interpretative Phenomenological Analysis was used to develop themes.

Results

Six main themes were extracted: (1) Living the diagnosis as a shock; (2) You should not sleep on it: the importance of prevention; (3) The adjustment to CPAP; (4) Barriers and facilitators to the use of CPAP; (5) Three in a bed; and (6) The relationship with the healthcare system.

Conclusion

Results of this study suggest potential avenues for interventions to increase adherence to CPAP, including the provision of information and continued support. Individual counseling providing strategies aimed at helping the person to cope with the emotional problem and relational difficulties associated with the use of CPAP, and at strengthening self-efficacy and self-management skills are also encouraged for optimal care during the rehabilitation program.
