Spousal involvement and CPAP adherence: a dyadic perspective

Efficacy of pulmonary rehabilitation in patients with chronic obstructive pulmonary disease and obstructive sleep apnea; a randomized controlled trial

OBJECTIVE

To evaluate the efficacy of pulmonary rehabilitation in the outcomes of patients with chronic obstructive pulmonary disease-obstructive sleep apnoea overlap syndrome patients who used positive airway pressure.

DESIGN

Prospective randomized controlled single- blind trial.

PATIENTS

A total of 79 patients with chronic obstructive pulmonary disease-obstructive sleep apnoea overlap syndrome were randomly assigned to either the intervention group (n = 40) or control group (n = 39).

METHODS

All patients consistently adhered to positive airway pressure therapy every night from enrolment in the study, while intervention group patients received additional moderate-intensity aerobic exercise for 20 weeks. Pre- and post-intervention measurements included the 6-Minute Walk Test, Barthel Index, body mass index, fat mass, free fat mass, forced expiratory volume in 1 s (FEV1), FEV1%predicted, modified Medical Research Council, and polysomnography parameters.

RESULTS

After 20 weeks, the intervention group exhibited statistically significant improvements in 6MWD, Barthel Index, body mass index, fat mass, and modified Medical Research Council compared with control group (all p < 0.01). In addition, the intervention group showed a significantly lower percentage of total sleep time with oxygen saturation < 90% (p = 0.013) and higher lowest nocturnal oxygen saturation (p = 0.008) than the control group. However, there was no significant difference in FEV1 %predicted between the 2 groups.

CONCLUSION

Pulmonary rehabilitation incorporating moderate-intensity aerobic exercise could improve physical endurance and motor abilities in individuals with chronic obstructive pulmonary disease-obstructive sleep apnoea overlap syndrome, while also improving anamnestic dyspnoea, body composition, and sleep-disordered breathing.

Impacts of conservative treatment on the clinical manifestations of obstructive sleep apnea-systematic review and meta-analysis

INTRODUCTION

Obstructive sleep apnea (OSA) is a chronic disease with a high populational prevalence that is characterized as airway closure during sleep. Treatment is multidisciplinary and varies according to each case. Continuous positive airway pressure (CPAP), oral appliances, and surgery are the primary therapeutic options. Non-invasive conservative treatments such as sleep hygiene, positional therapy, physical exercises, and weight loss aim to reduce the worsening of the disease while being complementary to the invasive primary treatment.

OBJECTIVE

To analyze the impact of non-invasive conservative therapies on the clinical manifestations of OSA syndrome (OSA), compared with other interventions.

METHOD

This was a systematic review with meta-analysis. The searches were performed without filters for the time period, type of publication, or language. Randomized clinical trials on subjects over 18 years of age diagnosed with untreated OSA were included. Responses to non-invasive conservative treatment were compared with responses to the primary intervention. Primary outcomes were assessed using the Epworth Sleepiness Scale and/or Functional Outcomes of Sleep Questionnaire (FOSQ).

RESULTS

A total of eight studies were included in the review. The heterogeneity of the effect was estimated at 89.77%. Six studies compared conservative treatment with CPAP, one with oral appliances, and one with oropharyngeal exercises. Using the Epworth Sleepiness Scale measurements, the standardized difference in the estimated means, based on the random-effects model, was 0.457 (95% CI (1.082 to 0.169)) and the mean result did not differ significantly from zero (z = 1.43; p = 0.153). The conservative therapies assessed in this study improved the subjective quality of sleep, although the post-treatment ESE scores did not show significant results. The reduction in AHI and better outcomes in the evaluated domains, as well as in cognition and mood, were superior in the groups that received CPAP and IOD.

CONCLUSION

The most commonly used treatments of choice for OSA are invasive, including the use of CPAP, oral appliances, and surgeries, being the most utilized options. This study demonstrated that non-invasive conservative treatments, such as sleep hygiene, yield results as effective as invasive treatments. Further studies are needed to confirm this result and to predict whether invasive treatment can be used as the primary treatment or only as a supplement.

Bed partner perception of CPAP therapy on relationship satisfaction and intimacy-A European perspective from the ESADA network

Obstructive sleep apnea increases morbidity and mortality risks. The most common treatment is continuous positive airway pressure, with nasal mask usage being important, but not always optimal. While most research on treatment adherence focuses on the patient, the bed partner's involvement may be detrimental. Our study aim is to obtain a European-wide picture of the bed partner's attitude and support towards continuous positive airway pressure therapy, including effects on relationship satisfaction and intimacy. The English translation of a German bed partner questionnaire, assessing relationship satisfaction and three major components (general attitude, perceived mask looks, intimacy effects) was distributed within the European Sleep Apnea Database Network and translated in participating countries' local language. Data were collected for 2 years. In total, 10 European countries (13 sleep centres) participated with 1546 questionnaires. Overall, 91% of bed partners had a positive attitude towards continuous positive airway pressure therapy, 86% perceived mask looks not negative, 64% stated no negative intimacy effects. More specifically, 71% mentioned improved sleep quality, 68% supported nightly device usage. For 41% of bed partners, relationship satisfaction increased (no change for 47%). These results were significantly more pronounced in Eastern/Southern Europe compared with Middle Europe, especially regarding intimacy effects. However, increased continuous positive airway pressure therapy length affected attitude negatively. These results provide necessary information to improve treatment strategies by including educational couple-focused approaches. Among others, we revealed that negative intimacy effects are not considered a barrier to continuous positive airway pressure adherence. These results may inspire more research identifying regional gaps with need for treatment adjustments.

Personality traits and pre-treatment beliefs and cognitions predicting patient adherence to continuous positive airway pressure: A systematic review

Adherence to Continuous Positive Airway Pressure (CPAP) for obstructive sleep apnoea (OSA) can be improved by behavioural interventions which modify patients' beliefs and cognitions about OSA, CPAP, and themselves. We have conducted the first systematic review of the literature on beliefs and cognitions held before starting treatment, and personality (which influences the former) that predict the decision to purchase or start CPAP, or CPAP adherence one month or more after CPAP initiation. A systematic search and screen of articles identified 21 eligible publications from an initial 1317. Quality assessment performed using an adapted Newcastle-Ottawa Scale demonstrated that 13 (62%) studies were poor quality and only seven (33%) were high quality. Eighteen factors, such as self-efficacy (confidence) in using CPAP and value placed on health predicted CPAP adherence; however, for only six (33%), utility as an intervention target is known, from calculation of individual predictive power. Studies did not use new behavioural frameworks effective at explaining adherence behaviours, nor did they interview patients to collect in-depth data on barriers and facilitators of CPAP use. Future studies cannot have these limitations if high quality evidence is to be generated for intervention development, which is currently sparse as highlighted by this review.

Nocturnal positive pressure ventilation improves relationship satisfaction of patients with OSA and their partners

OBJECTIVE

Continuous positive airway pressure (CPAP) ventilation is considered the therapeutic standard for obstructed sleep apnea (OSA). Therapy success may also be affected by the patient's bed partner. A questionnaire was developed and tested that measures the attitude of the bed partner towards CPAP therapy and relationship effects.

METHODS

A new questionnaire to capture bed partners' attitude towards CPAP mask therapy was used with an anonymous sample of 508 bed partners. Possible constructs underlying the attitude of the bed partner towards mask appearance have been investigated by means of a Principal Components Analysis.

RESULTS

The survey revealed bed partners' positive attitude towards their partner's CPAP therapy (over 90% of bed partners were happy with the therapy, over 75% would recommend the therapy). Importantly, the bed partners' satisfaction with the relationship increased significantly during CPAP therapy (before therapy: 49% were satisfied, after therapy initiation: 70%; p<.001). There was a strong correlation between support for CPAP therapy and improved sleep quality of bed partners (r = 0.352, p>.001). Furthermore, the validation of the questionnaire through principal components analysis revealed three major factors: Attitude (of the bed partner towards CPAP therapy), Looks (of the mask perceived by the bed partner), Intimacy (effect of CPAP therapy on relationship and intimacy).

CONCLUSION

Both, the OSA patient and the bed partner benefit from CPAP therapy. This is the first bed partner questionnaire - interviewing the bed partner alone and anonymously - that showed that CPAP therapy also positively influences the relationship. We recommend that the bed partner be involved in the CPAP treatment from the start of therapy.

Positive airway pressure adherence among patients with obstructive sleep apnea and cognitive impairment: A narrative review

Adults with Mild Cognitive Impairment (MCI) and Alzheimer's disease (AD) have increased rates of Obstructive Sleep Apnea (OSA). Positive Airway Pressure (PAP) is the first-line treatment for OSA and may have potential benefits for slowing cognitive decline in these individuals. However, adherence is low in PAP users overall and those with cognitive impairment may have unique challenges. Furthermore, there has been little systematic study of the use of PAP or strategies to enhance PAP adherence among those with AD or MCI. The aim of this review is to examine existing observational, quasi-experimental and experimental studies of the effects of PAP on cognitive function. In addition, our goal was to gather evidence about the adherence rates, and support for PAP among adults with MCI and mild to moderate AD. Through searches of electronic databases (University of Utah Library, SAGE Publishing, PubMed, Wiley, EBSCO, Science Direct, ProQuest, and NCBI), we identified 11 articles that fit our study inclusion criteria. Synthesis of data was performed with a focus on cognitive outcomes of PAP interventions and adherence. Findings from the studies showed that multiple indices of memory improved with PAP use. Adherence in MCI and AD populations was largely comparable to adherence reported in general adult populations, but more research is needed to optimize systems for providing support for PAP users and caregivers. Results support PAP as a promising intervention in this population but more research is needed to make definitive conclusions about the relationship between PAP use and improved cognitive function. Furthermore, research is needed to determine if additional interventions are needed to support patients and caregivers.

Impact of Obstructive Sleep Apnea Treatment on Marital Relationships: Sleeping Together Again?

Objective We assess the impact of obstructive sleep apnea (OSA) treatment on the quality of marital relationships. Moreover, we evaluate the proportion of couples sleeping separately before treatment and whether there was any change after treatment began, which is still little explored in the literature. Methods A prospective study was conducted between April 2021 and April 2023, with users diagnosed with OSA in a level 2 hospital in Portugal. A questionnaire was applied before and after the start of treatment to both user and partner, which included questions on whether they slept together or separately, the disturbing factors of sleep quality, and satisfaction with the marital relationship. Statistical analysis was performed using R (version 4.2.2; R Development Core Team, Vienna, Austria). Results Seventy questionnaires were applied, 79% to male users. Forty-one percent of users reported that they slept at least once or twice a month separated from their spouse, and, of these, 41% always slept in separate rooms. The chief complaints of partners not sleeping together were snoring (86%), restless sleep (17%), and witnessed apnea (14%). After treatment, 72.4% started to sleep together again, with a statistically significant difference in the condition before and after intervention. Among all patients, 69% said that their personal lives had improved and, when asked the same question to their spouse, 74% recognized the benefit of therapy. Conclusion Starting treatment positively influenced the quality of the marital relationship of users and their partners, with a statistically significant proportion of couples sleeping together again.

Experiences with Continuous Positive Airway Pressure Among African American Patients and their Bed Partners

RATIONALE

Despite having a higher prevalence and severity of obstructive sleep apnea (OSA), African Americans have lower adherence to continuous positive airway pressure (CPAP) compared to other groups. Information regarding challenges faced by African Americans prescribed CPAP are lacking.

OBJECTIVES

To determine the barriers and facilitators to optimal management of OSA with CPAP among African Americans and to understand the role bed partners may play.

METHODS

We conducted semi-structured in-depth interviews via video conferencing with African American patients of an urban safety-net health care system with OSA prescribed CPAP and their bed partners. Recruitment continued until theoretical saturation was achieved. Verbatim transcripts were analyzed using the principles of thematic analysis.

RESULTS

15 patients (12 women) diagnosed with OSA and prescribed CPAP a mean 2.6 years prior along with 15 bed partners (3 women) were individually interviewed. Four themes emerged regarding impediments to CPAP use: 1) inadequate education and support, 2) CPAP maintenance and hygiene, 3) inconvenient design of CPAP interfaces, and 4) impediment to intimacy. Four themes emerged as facilitators to CPAP use: 1) provider and technical support, 2) properly fitted CPAP masks, 3) active support from partner and family, and 4) experiencing positive results from CPAP.

CONCLUSIONS

African American patients with OSA and their bed partners identified several unique barriers and facilitators to CPAP use. Active involvement by bed partners was considered by both patients and partners as helpful in improving CPAP adherence. Interventions to improve OSA outcomes in this population should focus on patients and their bed partners.

Partner Alliance to Enhance Efficacy and Adherence of CBT-I

Cognitive behavioral therapy for insomnia (CBT-I) is now widely recognized as the first-line management strategy for insomnia, both for insomnia in its "pure" form, and when comorbid with a physical or psychological illness. However, there is a definite need to develop and test both alternative and adjunct interventions to CBT-I, before implementing them into routine practice. The aim of this article is to provide a narrative review of the literature with regard to what is known about the influence of partners on sleep, insomnia, and its management.

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.

Couples-based interventions to promote PAP adherence among older adults: a qualitative study of patients, partners, and providers

STUDY OBJECTIVES

Bed partners play a critical role in the treatment of obstructive sleep apnea and are affected by the treatment (or lack thereof) of their partner's obstructive sleep apnea, but few studies have included partners formally in treatment. In this qualitative study, we examine key stakeholder perspectives (patient, bedpartner, and sleep medicine provider) to inform the development of a novel, couples-based intervention to promote adherence to positive airway pressure (PAP) and sleep health among older adult couples.

METHODS

We conducted 3 focus group discussions with patients with obstructive sleep apnea/using PAP and their partners and 3 focus group discussions with sleep medicine providers. A standard interview guide was used to gather stakeholder input: (1) to understand interdependence of sleep among couples with sleep apnea; (2) to understand collaborative strategies that couples are currently using to address their sleep health challenges, including their perceptions of what is helpful vs not helpful; and (3) feasibility of the intervention design and delivery. Interviews were transcribed and thematically analyzed.

RESULTS

Participants (n = 25) included 9 patients, 7 partners, and 9 providers. Analysis of the discussion identified themes within the 3 topics addressed in the focus group discussions: (1) interdependence of sleep health among couples, (2) collaboration and other dyadic strategies for increasing PAP use, and (3) facilitators and barriers to a couples-based PAP adherence intervention. Results of the focus group discussions provided new insights into collaborative strategies that could be used to enhance the sleep health of both patients and partners. Patient/partners reported that a couples-based treatment could reduce common frustrations experienced by new PAP users, thereby benefiting their relationship. However, barriers to couples-based treatment included patients and partners feeling overwhelmed and reluctance to discuss intimacy. Providers recognized the benefits of involving partners but reported concern about exacerbating conflict in the couple.

CONCLUSIONS

Results indicate that couples and providers are enthusiastic about couples-based treatment that addresses their individual and dyadic sleep health challenges and identified important barriers that will need to be addressed to enhance uptake by clinicians and participation/retention of couples.

Developing OurSleepKit: A Couple-focused mHealth Tool to Support Adherence to Positive Airway Pressure Treatment

BACKGROUND AND AIM

Existing interventions promoting positive airway pressure (PAP) adherence focus only on the diagnosed individual, despite the fact that partners are often the most impacted by obstructive sleep apnea (OSA), and are delivered mostly by health professionals, with limited success. The goal of this work is to develop a prototype of OurSleepKit, a couple-focused mobile health (mHealth) tool to coach mutual engagement and promote adherence to PAP treatment.

METHODS

We used an iterative participatory approach working with future end users of OurSleepKit to support the development of this prototype. We conducted a total of 14 semi-structured in-depth open-ended dyadic interviews with OSA patients and their partners. Phase 1 of the development was to inform key functions of an engaging tool. Phase 2 focused on developing functions to engage positive conversation in the dyad and obtained feedback for this initial prototype.

RESULTS

The OurSleepKit prototype was developed and demonstrated high acceptability and engagement. Three key functions included periodic assessments based on developmental stages of PAP treatment, a Coaching Board which provides customized and dynamically updated support content - primarily brief story-telling videos featuring real-life couples' experiences - and timely tailored prompts (for action, learning, and conversation) through push notifications in the evening to facilitate positive conversation in the dyad and offer in-the-moment support for PAP use.

CONCLUSIONS

Going beyond the traditional and prevailing view of PAP use as an individual phenomenon, OurSleepKit is a novel mHealth intervention engaging both the patient and partner holding great promise to promote PAP adherence.

Rationale and study protocol for We-PAP: a randomized pilot/feasibility trial of a couples-based intervention to promote PAP adherence and sleep health compared to an educational control

BACKGROUND

Obstructive sleep apnea (OSA) is a serious health condition that affects approximately 30-50% of older adults and contributes to risk for cardiometabolic disorders and dementia. Despite the well-documented role of partners in treatment seeking and adherence to positive airway pressure (PAP), treatments for OSA have nearly exclusively focused on the patient and current treatments for OSA do not address co-existing sleep problems such as insomnia that are prevalent in both patients with OSA and their partners. Therefore, the goal of this study is to develop and test a novel couples-based sleep health intervention to promote adherence to PAP and improve sleep health of the couple.

METHODS

We are conducting a two-arm, parallel group, single blind, randomized controlled pilot/feasibility trial to compare our novel couples-based sleep health intervention (We-PAP) to an information control group (IC). We-PAP is based on a transdiagnostic model and uses a dyadic approach including increasing effective partner support, communication skills, and couple-level goal-setting. We-PAP involves 3 sessions and delivered via telehealth in weekly sessions. The IC includes standardized patient educational materials. Both groups receive the usual follow-up with their medical team. The study involves assessments at pre-treatment, post-intervention (approximately 1 month after starting PAP and completing We-PAP sessions or IC) and 3 months after starting PAP. Our main outcomes are feasibility and acceptability ratings. Secondary outcomes include comparing We-PAP to IC for PAP adherence, sleep quality (self-report and objective) and cognitive measures.

DISCUSSION

We-PAP is the first couples-based transdiagnostic sleep health intervention for patients with OSA and their partners. Results of this study will be used to inform the design of a subsequent fully powered clinical trial. If successful, this intervention could significantly advance current clinical practice in the treatment of OSA and sleep health more comprehensively in older adults. Moreover, this intervention may be useful for improving sleep in other aging populations with multiple sleep and other health problems, including patients with chronic illnesses or those at risk for Alzheimer's disease and their caregivers.

Validation of the French Cues to CPAP Use Questionnaire in patients with OSAS: A step forward for evaluating cues to CPAP use in order to predict treatment adherence

PURPOSE

The cues to starting CPAP are important in patients with Obstructive Sleep Apnea Syndrome (OSAS) to predict CPAP use and behavioral change. The Cues to CPAP Use Questionnaire (CCUQ) is a short practical self-reported scale to evaluate such cues to action. This study sought to examine the psychometric reliability and validity of the French version.

METHODS

A forward-backward translation of the CCUQ was performed. Principal research tools were CCUQ, SEMSA and ESS. Subjects with OSAS were invited to complete the CCUQ just before CPAP initiation and 10 days after CPAP initiation. The ESS was completed just before CPAP initiation and one month after CPAP initiation. The SEMSA was completed just before CPAP initiation. Statistical analyses methods aim to evaluate the psychometric properties of the French CCUQ version in terms of its construct validity, internal structural validity, test-retest and external validity. Mean CPAP use on the previous month was recorded at one, six and twelve months after CPAP initiation.

RESULTS

A total of 140 patients with OSAS were included with 61.4% of men and a mean age of 55.3 (±12.9), BMI of 29.8 (±4.9), initial ESS of 11.97 (±5.68), and initial AHI 37.2/h (±19.3). Factor analysis confirmed the three-factor structure of the CCUQ. Cronbach's alpha coefficient was 0.64. Test-retest reliability (at t-0 and at 10 days) of the CCUQ was satisfactory. External validity shown significant correlation of the CCUQ with SEMSA and of the dimension "Partner cues" of the CCUQ with mean CPAP use at one month.

CONCLUSION

The French CCUQ scale is a reliable and valid tool for measuring cues to action in adults with OSAS initiating CPAP treatment. Further studies are necessary to confirm the predictive value of cues to action and self-efficacy for CPAP use and adherence. Such investigations would underpin public health CPAP interventions in accordance with models of behavioral change.

Intimate Relationships and Coronary Heart Disease: Implications for Risk, Prevention, and Patient Management

PURPOSE OF REVIEW

Research and clinical services addressing psychosocial aspects of coronary heart disease (CHD) typically emphasize individuals, focusing less on the context of intimate relationships such as marriage and similar partnerships. This review describes current evidence regarding the role of intimate relationships in the development, course, and management of CHD.

RECENT FINDINGS

Having an intimate partner is associated with reduced risk of incident CHD and a better prognosis among patients, but strain (e.g., conflict) and disruption (i.e., separation, divorce) in these relationships are associated with increased risk and poor outcomes. These associations likely reflect mechanisms involving health behavior and the physiological effects of emotion and stress. Importantly, many other well-established psychosocial risk and protective factors (e.g., low SES, job stress, depression, and optimism) are strongly related to the quality of intimate relationships, and these associations likely contribute to the effects of those other psychosocial factors. For better or worse, intimate partners can also affect the outcome of efforts to alter health behaviors (physical activity, diet, smoking, and medication adherence) central in the prevention and management CHD. Intimate partners also influence-and are influenced by-stressful aspects of acute coronary crises and longer-term patient adjustment and management. Evidence on each of these roles of intimate relationships in CHD is considerable, but direct demonstrations of the value of couple assessments and interventions are limited, although preliminary research is promising. Research needed to close this gap must also address issues of diversity, disparities, and inequity that have strong parallels in CHD and intimate relationships.

Telehealth Technology Application in Enhancing Continuous Positive Airway Pressure Adherence in Obstructive Sleep Apnea Patients: A Review of Current Evidence

Obstructive sleep apnea (OSA) is a common type of sleep-disordered breathing associated with multiple comorbidities. Continuous positive airway pressure (CPAP) is the first choice for moderate-severe OSA but poor compliance brings a great challenge to its effectiveness. Telehealth interventions ease the follow-up process and allow healthcare facilities to provide consistent care. Fifth-generation wireless transmission technology has also greatly rationalized the wide use of telemedicine. Herein, we review the efficacy of the telehealth system in enhancing CPAP adherence. We recommend applying telemonitoring in clinical practice and advocate the development of a biopsychosocial telemedicine model with the integration of several interventions. Big databases and promising artificial intelligent technologies make clinical decision support systems and predictive models based on these databases possible.

Facilitators and barriers to getting obstructive sleep apnea diagnosed: perspectives from patients and their partners

STUDY OBJECTIVES

Obstructive sleep apnea (OSA) is a prevalent and debilitating condition that is significantly underdiagnosed. The majority of adults sleep with someone-a partner. Partners can play a significant role in the patient's OSA diagnosis. The goal of this work is to describe facilitators and barriers to OSA diagnosis as discussed by patients with OSA and their partners.

METHODS

This was a qualitative secondary analysis with results drawn from 20 dyadic interviews, conducted 1 couple at a time, in 20 newly diagnosed adult patients with OSA and their partners. Qualitative interview data were analyzed using conventional content analysis.

RESULTS

Facilitators of OSA diagnosis were partners pushing patients to seek care, patients actively seeking care, and care providers identifying the patient's risk of OSA. Barriers to OSA diagnosis were patients' lack of serious attention to symptoms, patients' negative perceptual framing of diagnosis and treatment of OSA, and poor coordination of health care services.

CONCLUSIONS

We recommend engaging partners in the OSA diagnosis and developing educational and behavioral interventions to raise public awareness about OSA. It is important to educate clinicians on atypical presentations of OSA. Further investigation is needed to evaluate the impact of health care services on OSA diagnosis.

Continuous positive airway pressure adherence in people with obstructive sleep apnoea

OBJECTIVES

This cross-sectional study aimed to identify whether five factors of the health belief model were related to continuous positive airway pressure adherence in Thai people with obstructive sleep apnoea.

BACKGROUND

Obstructive sleep apnoea is a disorder impacting health, social wellbeing and the economy. Continuous positive airway pressure is a gold standard of treatment; however, poor adherence to treatment is an important issue that is related to a multiplicity of psychological and behavioural factors.

METHODS

The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist for cross-sectional studies was used to report the study. Purposive sampling was used to recruit 94 patients newly diagnosed with sleep apnoea and using CPAP devices from a sleep clinic. Participants completed a demographic record, the Thai versions of the Functional Outcomes of Sleep Questionnaire, the Perceived Barriers Questionnaire and the Self-Efficacy Measure for Sleep Apnea. CPAP adherence was measured by using information downloaded from the smart card of the devices. Data were analysed using descriptive statistics and logistic regression.

RESULTS

Only 54.3% of participants adhered to CPAP treatment using standard protocols. Perceived seriousness of their condition was significantly associated with CPAP adherence, whereas perceived susceptibility, benefits, barriers and self-efficacy were not.

CONCLUSIONS

We found a low rate of CPAP adherence among participants. The only factor related to CPAP adherence was perceived seriousness.

RELEVANCE FOR THE CLINICAL PRACTICE

With a low rate of CPAP adherence, healthcare professionals, especially nurses, should encourage patients to use CPAP regularly by providing them with support and education regarding the severity of the disease if untreated and the benefits of CPAP treatment on the disease. Healthcare professionals should be aware of psychological factors impacting patients' perception of sleep apnoea and CPAP treatment. Interventions dealing with these factors should be developed and implemented in practice.

Effects of solriamfetol in a long-term trial of participants with obstructive sleep apnea who are adherent or nonadherent to airway therapy

STUDY OBJECTIVES

Solriamfetol, a dopamine/norepinephrine reuptake inhibitor, is approved in the United States and European Union to treat excessive daytime sleepiness in patients with obstructive sleep apnea (OSA) (37.5-150 mg/day) and narcolepsy (75-150 mg/day). This analysis evaluated solriamfetol's efficacy in subgroups of participants with OSA who were adherent or nonadherent to primary OSA therapy at baseline and examined whether solriamfetol affected the use of primary therapy in an open-label extension trial.

METHODS

Participants with OSA who completed prior solriamfetol studies received solriamfetol 75, 150, or 300 mg/day for ≤ 52 weeks. The main efficacy outcome was the Epworth Sleepiness Scale score. Primary therapy use was summarized as the percentage of nights, the number of hours/night, and the percentage of nights with use ≥ 50%/night (%). Efficacy and primary therapy use are reported for participants who directly enrolled from a previous 12-week study and had ≤ 40 weeks of open-label treatment (n = 333). Safety data are reported for all participants (n = 417).

RESULTS

Mean ESS scores in adherent (n = 255) and nonadherent (n = 78) subgroups, respectively, were 15.0 and 15.8 at baseline (of 12-week study) and 6.5 and 6.8 at week 40. For participants using an airway therapy, mean use at baseline was 90% of nights, 6.6 hours/night, and use ≥ 50%/night on 90% of nights; changes from baseline to week 40 were minimal (0.9%, -0.8 hours, and 6.5%, respectively). Common adverse events (both subgroups) included headache, nasopharyngitis, insomnia, dry mouth, nausea, anxiety, and upper respiratory tract infection.

CONCLUSIONS

Long-term efficacy and safety of solriamfetol were similar regardless of adherence to primary OSA therapy. Solriamfetol did not affect primary therapy use.

Experiences of Using Positive Airway Pressure for Treatment of Obstructive Sleep Apnoea: A Systematic Review and Thematic Synthesis

STUDY OBJECTIVES

Sub-optimal use of positive airway pressure (PAP) to treat obstructive sleep apnoea (OSA) continues to be a major challenge to effective treatment. Meanwhile, the individual and societal impacts of untreated OSA make effective treatment a priority. Although extensive research has been conducted into factors that impact PAP use, it is estimated that at least half of users do not use it as prescribed. However, the voice of users is notably minimal in the literature. A systematic review and qualitative metasynthesis of PAP user experience was conducted to contribute to understandings of how PAP is experienced and to inform how usage could be improved.

METHODS

PsycINFO, MEDLINE, CINAHL and EMBASE databases were systematically searched. Primary research findings of adult experiences using PAP that had been inductively analysed were included. Papers were critically appraised using the CASP qualitative checklist to generate a "hierarchy of evidence". Thematic synthesis was then conducted to generate analytical themes. Results were presented in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA).

RESULTS

25 papers reporting on over 398 people's experiences were analysed to generate 4 themes: Journey to PAP, Discomfort from and around PAP, Adapting to and using PAP, and Benefits from PAP. Author reflexivity and vulnerability to bias is acknowledged.

CONCLUSIONS

The findings highlight the applicability of a biopsychosocial understanding to PAP use. This metasynthesis gave voice to user experiences, revealing barriers to PAP use at a healthcare service level across the world, and suggests ways services can address these barriers.

Summary and Update on Behavioral Interventions for Improving Adherence with Positive Airway Pressure Treatment in Adults

Continuous positive airway pressure (PAP) is still the most efficacious treatment for obstructive sleep apnea when used effectively. Since the availability of PAP 39 years ago there have been considerable technological advances, such as quieter, lighter and smaller machines with better humidification. However, adherence to treatment is still a major problem. This article reviews studies published on behavioral interventions aimed at improving the uptake and maintenance of PAP treatment (January 2016-February 2020). It discusses underlying factors in the poor uptake and discontinuation of treatment and the role of qualitative research to better understand the perspective of the patients.

Utility of Multi-Theory Model (MTM) to Explain the Intention for PAP Adherence in Newly Diagnosed Sleep Apnea Patients

PURPOSE

The objective of this study was to assess the utility of a fourth-generation multi-theory model (MTM) in explaining the intention for initiation and sustenance of PAP adherence among newly diagnosed sleep apnea patients.

PATIENTS AND METHODS

For this cross-sectional study, data were collected at a private sleep center located in the Southeastern United States. A total of 138 newly diagnosed patients with sleep apnea who had been prescribed PAP therapy completed a valid and reliable 41-item MTM instrument. Stepwise multiple regression modeling was conducted to assess MTM based explanatory variables of PAP adherence in this study sample.

RESULTS

MTM constructs namely participatory dialogue (β = 0.17, p = 0.014), behavioral confidence (β = 0.48, p < 0.001), and changes in the physical environment (β = 0.26, p = 0.001) were statistically significant predictors of the intention for initiation of PAP therapy and accounted for 53.5% of the variance. Emotional transformation (β = 0.57, p < 0.001), changes in the social environment (β = 0.16, p = 0.016), and practice for change (β = 0.16, p = 0.047) were statistically significant predictors of the intention for sustenance of PAP therapy and accounted for 60.6% of the variance.

CONCLUSION

The MTM was found to be a promising theoretical model in explaining the intention for initiation and sustenance of PAP therapy.

Treatment of Obstructive Sleep Apnea: Achieving Adherence to Positive Airway Pressure Treatment and Dealing with Complications

Obstructive sleep apnea is a common and treatable condition, but therapeutic adherence is limited by numerous factors. Despite advances in positive airway pressure (PAP) technology and a multitude of effective pharmacologic and behavioral therapeutic interventions to overcome the most common barriers to PAP, adherence has not increased significantly over the past 30 years. This review aims to identify the most important factors that impact adherence, common barriers to treatment, and evidence-based treatment strategies to maximize the effectiveness of PAP treatment. Complications of PAP treatment and mitigation techniques are also discussed.

A Couples-Oriented Intervention for Positive Airway Pressure Therapy Adherence: A Pilot Study of Obstructive Sleep Apnea Patients and Their Partners

Background: Partner involvement can influence positive airway pressure (PAP) therapy use among patients with obstructive sleep apnea (OSA). This study assessed the feasibility, acceptability, and preliminary efficacy of a couples-oriented education and support (CES) intervention for PAP adherence. Participants: Thirty newly diagnosed OSA patients and their partners were randomly assigned to one of three groups: an education and support intervention directed at both patient and partner (CES), an education and support intervention directed only at the patient (PES), or usual care (UC). Methods: Feasibility and acceptability were assessed through enrollment and posttreatment program evaluations, respectively. Assessments of sleep quality, daytime sleepiness, and daytime function were obtained from both patients and partners at baseline and 3 months after PAP initiation. Objective PAP adherence was assessed at 1 week, 1 month, and 3 months. Results: Recruitment and attrition data suggest adequate feasibility. All patients and partners in the CES group reported that the intervention was helpful. Patients in the CES and PES groups increased their PAP adherence over the first month of treatment, whereas PAP adherence decreased over this period in the UC group. For patients, large to medium effects for sleep quality (d = -1.01), daytime sleepiness (d = -0.51), and daytime function (d = 0.51) were found for the CES group. The PES and UC groups effect sizes were large to small for sleep quality (d = -0.94; d = -0.40), daytime sleepiness (d = -0.42; d = -0.82), and daytime function (d = 0.41; d = 0.57), respectively. For partners, large effects for daytime sleepiness (d = -1.31) and daytime function (d = 1.54) and small to medium effect for sleep quality (d = -0.31) were found for the CES group. Worsening of sleep quality (d = 0.65) and no change in daytime sleepiness or daytime function were found for the PES group. For the UC group, medium to large effects were found for sleep quality (d = -0.77), daytime sleepiness (d = -0.77), and daytime function (d = 0.65). Conclusions: The findings of this pilot study provide support for taking a couples intervention approach to improve PAP adherence.

Centers for Medicare and Medicaid Services Positive Airway Pressure Adherence Criteria May Limit Treatment to Many Medicare Beneficiaries

STUDY OBJECTIVES

Centers for Medicare and Medicaid Services (CMS) reimbursement for positive airway pressure (PAP) devices for obstructive sleep apnea treatment is dependent on patients meeting adherence expectations within the first 3 months on therapy. Adherence is defined as usage of the device for at least 4 hours per night on 70% of nights during a consecutive 30-day period. We hypothesize that the adherence pattern may be established beyond this initial period, which may limit the opportunity to treat many patients.

METHODS

Treatment and adherence data from PAP devices were monitored via wireless modems for 42 consecutive PAP-naïve military veterans who completed 1 year of nightly monitoring. Their baseline characteristics were as follows: age (mean ± standard deviation) 58.5 ± 12.5 years; body mass index 33.7 ± 5.7 kg/m²; diagnostic apnea-hypopnea index (pretreatment) 28.1 ± 18.5 events/h; apnea-hypopnea index on PAP: 4.3 ± 3.3 events/h. We examined daily, monthly, quarterly, semiannual, and annual reports, and the best 30-day adherence report for each quarter.

RESULTS

In the first 3 months, 19 of 42 participants were adherent by CMS criteria, and 23 of 42 participants were not. Of the 19 adherent participants, 13 remained adherent and 6 became nonadherent or stopped PAP treatment for the remainder of the year. In the 23 initially nonadherent participants, 16 stopped PAP treatment, and 7 participants (30.4%) became adherent (using CMS criteria) during the rest of the year. Thus, PAP adherence during the first 3 months was predictive for the rest of the year in only 68.4%. PAP nonadherence during the first 3 months was predictive for further nonadherence in only 69.6% of the cases. Overall, this led to a 65% sensitivity and 72% specificity of using adherence at 3 months in predicting adherence at 1 year.

CONCLUSIONS

CMS adherence criteria affecting PAP coverage are restrictive and can result in the withholding of therapy in many patients who otherwise might become adherent.

Marital quality, partner's engagement and continuous positive airway pressure adherence in obstructive sleep apnea

BACKGROUND

Continuous positive airway pressure (CPAP) is the first line therapy for obstructive sleep apnea (OSA) but its effectiveness requires high adherence. We aimed to assess the impacts of the spouse's/partner's involvement and the quality of the couple's relationship on CPAP adherence.

METHODS

In a multicenter prospective study conducted in France, patients reported their subjective views regarding their partner's engagement in their CPAP treatment and the quality of their marital relationship using the Quality of Marriage Index. A hierarchical linear model was built to assess the predictors of CPAP adherence at day 120. Structural equation modeling was performed to evaluate the direct and indirect effects of the spouse's/partner's engagement and the quality of the couple's relationship on CPAP adherence.

RESULTS

The 290 OSA patients were predominantly male (77%), with a median age of 53 years IQR: [46; 62], median BMI: 32 kg/m² [28.6; 35.9] and median apnea + hypopnea index: 43/per hour [33; 58]. Independent factors for CPAP adherence at day 120 were the partner's encouragement of CPAP usage and a stable relationship exceeding 30 years, although emotional support or collaboration were not associated with CPAP adherence. Structural equation modeling demonstrated that spouse's/partner's engagement is directly related to CPAP adherence and improvement of symptoms, and that CPAP adherence is a mediator of disease-specific health-related quality of life. Marital quality was a significant moderator of these interactions meaning that a spouse's/partner's engagement improved adherence only when the quality of marriage index was high.

CONCLUSION

Future research and integrated OSA management should systematically include and document the role of the spouse/partner in CPAP adherence.

Residual excessive sleepiness in patients with obstructive sleep apnea on treatment with continuous positive airway pressure

PURPOSE OF REVIEW

One of the most common causes of excessive daytime sleepiness in clinical practice is obstructive sleep apnea syndrome (OSAS). So far, continuous positive airway pressure (CPAP) is the most effective treatment for OSA. Some of the patients do not improve on CPAP and remain sleepy despite using CPAP.This review provides updated information about the possible causes of residual sleepiness whilst using the CPAP in patients with OSAS.

RECENT FINDINGS

Prevalence of OSAS has increased recently to 23.4% in women and 49.7% in men. Periodic limb movement, behaviorally induced insufficient sleep syndrome and depression are the most common causes of persistent sleepiness on CPAP. Residual sleepiness after exclusion of all possible causes is 6%.

SUMMARY

There is still lack of sufficient evidence about the accurate characteristics and possible causes of this residual sleepiness and how to address this in large prospective studies.

Couples' experiences with continuous positive airway pressure treatment: a dyadic perspective

OBJECTIVE

The majority of adults sleep with a partner, making sleep a dyadic experience. However, interventions to improve sleep have primarily focused on individuals. This qualitative analysis used a dyadic approach to identify facilitators and barriers to successful treatment of one of the most common sleep disorders, obstructive sleep apnea, with continuous positive airway pressure (CPAP).

METHODS

Twenty joint qualitative interviews were conducted with couples, one couple at a time, with a sample of 20 patients with obstructive sleep apnea and their partners to develop an understanding of couples' experiences with CPAP use. Interviews were audio recorded and transcribed. Conventional qualitative content analysis was used to analyze the interview data.

RESULTS

Facilitators of CPAP use were the following: the partner aiding diagnosis and treatment, couples working together using CPAP, the perceived benefits of CPAP for both partners, the patient being motivated to use CPAP for the benefit of the partner, and various types of support provided by the partner to encourage CPAP use. Major barriers to CPAP use were the following: anxiety related to CPAP use particularly in the beginning of therapy, bothersome equipment causing disruptions in sleep and bedtime routine, interruptions to intimacy, and concern about image change while wearing CPAP.

CONCLUSIONS

Findings from this study suggest that couple-directed interventions that advocate for a mutually engaging perspective and promote supportive relationships and positive dyadic coping may be targets for improving CPAP adherence. Further research evaluating the potential of couple-focused interventions to improve sleep health is warranted.

ROLE OF SPOUSAL INVOLVEMENT IN CONTINUOUS POSITIVE AIRWAY PRESSURE (CPAP) ADHERENCE IN PATIENTS WITH OBSTRUCTIVE SLEEP APNEA (OSA)

INTRODUCTION

Little is known about the impact of spousal involvement on continuous positive airway pressure (CPAP) adherence. The aim of this study was to determine whether spouse involvement affects adherence with CPAP therapy, and how this association varies with gender.

METHODS

194 subjects recruited from Apnea Positive Pressure Long Term Efficacy Study (APPLES) completed the Dyadic Adjustment Scale (DAS). The majority of participants were Caucasian (83%), and males (73%), with mean age of 56 years, mean BMI of 31 kg/m2. & 62% had severe OSA. The DAS is a validated 32-item self-report instrument measuring dyadic consensus, satisfaction, cohesion, and affectional expression. A high score in the DAS is indicative of a person's adjustment to the marriage. Additionally, questions related to spouse involvement with general health and CPAP use were asked. CPAP use was downloaded from the device and self-report, and compliance was defined as usage ≥ 4 h per night.

RESULTS

There were no significant differences in overall marital quality between the compliant and noncompliant subjects. However, level of spousal involvement was associated with increased CPAP adherence at 6 months (p=0.01). After stratifying for gender these results were significant only among males (p=0.03). Three years after completing APPLES, level of spousal involvement was not associated with CPAP compliance even after gender stratification.

CONCLUSION

Spousal involvement is important in determining CPAP compliance in males in the 1st 6 months after initiation of therapy but is not predictive of longer-term adherence. Involvement of the spouse should be considered an integral part of CPAP initiation procedures.

Impact of Obstructive Sleep Apnea and Its Treatments on Partners: A Literature Review

STUDY OBJECTIVES

Many adults sleep with a significant other; thus, sleep disorder symptoms and treatments of one partner are likely to impact the other partner's health. A literature review was conducted to examine the impact of obstructive sleep apnea (OSA) and OSA treatments on partner-assessed sleep and daytime functioning and partner involvement in OSA treatment.

METHODS

MEDLINE, EMBASE, and CINAHL searches yielded 38 pertinent quantitative and qualitative studies that described sleep and/or daytime functioning assessed in partners of patients with untreated OSA, sleep and/or daytime functioning assessed in partners who were referred for OSA treatment, including continuous positive airway pressure (CPAP) therapy, oral appliance (OA), or surgery, and/or associations between partner involvement and OSA treatment use.

RESULTS

The majority of studies found untreated OSA to have a negative impact on partners' objective and subjective sleep and daytime functioning, in particular mood, quality of life, and relationship quality. Improvements in partner-assessed sleep quality were reported for CPAP, OA, and surgery. Conflicting results were reported for partners' mood, quality of life, daytime sleepiness, and relationship quality. Perceived partner support was associated with greater CPAP use.

CONCLUSIONS

Symptoms associated with OSA can negatively impact partners' sleep and daytime functioning. Treatment of OSA with CPAP, OA, or surgery can have health benefits for not only patients but also partners. Collaborative partner involvement may be a useful strategy for interventions promoting CPAP adherence.

Patient-centered care in obstructive sleep apnea: A vision for the future

Obstructive sleep apnea is a common condition, with multiple potential neurocognitive, cardiovascular, and metabolic consequences. Efficacious treatment is available, but patient engagement is typically required for treatment to be effective. Patients with sleep apnea are phenotypically diverse and have individual needs, preferences, and values that impact treatment decisions. There has been a shift in obstructive sleep apnea management from diagnosis to chronic care management. Making treatment decisions that incorporate an individual patient's values and preferences and are personalized for that patient's biology has the potential to improve patient outcomes. A patient-centered care approach in obstructive sleep apnea is reviewed including 1) determining patient-specific needs to guide treatment decisions, 2) understanding patient values, preferences, and other factors impacting treatment decisions and using shared decision-making, 3) enhancing patient education and support to improve treatment adherence, 4) promoting patient engagement, 5) optimizing care coordination, continuity of care, and access to care, and 6) determining and assessing patient-centered outcomes.

A Narrative Review of How Sleep-Related Breathing Disorders and Cardiovascular Diseases Are Linked: An Update for Advanced Practice Registered Nurses

PURPOSE/OBJECTIVES

Sleep-related breathing disorders (SRBDs), including obstructive sleep apnea and central sleep apnea, are common among patients with cardiovascular disease (CVD), but clinicians often do not pay enough attention to SRBDs. The purpose of this narrative review is to update advanced practice registered nurses on the literature focusing on the relationship between SRBDs and CVD (eg, hypertension, heart failure, coronary artery disease, arrhythmias, and stroke) and on treatments that can improve SRBDs in patients with CVD.

DESCRIPTION OF THE PROJECT

We conducted an electronic search of the literature published between 1980 and 2016 from PubMed, Cumulative Index to Nursing and Allied Health Literature, Web of Science, Academic Search Premier, and related health resource Web sites to address the aims of this study.

OUTCOMES

Fifty-six primary research articles (42 observational studies and 14 experimental and quasi-experimental studies) were selected based on our study aims and inclusion criteria. The studies revealed that individuals with CVD are at a greater risk for SRBDs and that SRBDs can worsen CVD. The findings from the studies also suggest that positive airway treatment could improve both SRBDs and CVD.

CONCLUSIONS

This review found a close relationship between SRBDs and CVD. Advanced practice registered nurses are in key positions to identify and help patients manage SRBDs. In particular, advanced practice registered nurses can educate staff and establish standards of practice to improve outcomes for patients with CVD.

Factors predicting CPAP adherence in obstructive sleep apnea syndrome

PURPOSE

Obstructive sleep apnea (OSA) is associated with a range of neurocognitive and cardiovascular complications, leading to a compromised quality of life. Continuous positive airway pressure (CPAP) is the gold standard therapeutic intervention for this disorder, yet patient compliance remains essential to its success. This study aimed at identifying the determinants of short-term and long-term CPAP adherence in a group of Lebanese patients.

METHODS

This cross-sectional study, conducted at the Sleep Center of Hôtel-Dieu de France hospital in Lebanon, included patients diagnosed with OSA and treated with CPAP for at least one night between June 2008 and January 2015. Adherence was assessed based on patients' self-report.

RESULTS

The study enrolled 138 patients. Adherence rate was 70.3 % at 6 months and around 50 % after 5 years. Cox models showed that use of nasal masks (HR 0.48, p = 0.048) and higher oxygen desaturation index at baseline (HR 0.98 p = 0.048) were associated with a better short-term CPAP adherence. Patients who bought their devices (HR 0.18, p < 0.001), those who were frequently contacted by the CPAP provider (HR 0.85, p 0.024), and those who reported improvement on treatment (HR 0.36, p < 0.001) were significantly more likely to remain adherent on the long term. Conversely, individuals on a diet plan tended to interrupt the treatment earlier (HR 4.85, p 0.039).

CONCLUSION

The present findings should be further explored in order to tailor interventions to the specific needs of different patient profiles and secure an improved CPAP adherence.
