Adherence to positive airway pressure treatment among minority populations in the US: A scoping review

Racial and ethnic differences in the receipt of continuous positive airway pressure treatment for obstructive sleep apnea

OBJECTIVE

To examine the pattern of health services access and utilization that may contribute to racial/ethnic disparities in receiving continuous positive airway pressure (CPAP) treatment for obstructive sleep apnea (OSA).

METHODS

This cross-sectional study used a national sample from the All of Us Research Program, which included over 80 % of participants from underrepresented populations in biomedical research. Study participants included adults aged 18 years and older diagnosed with OSA (N = 8518). Diagnosis of OSA and CPAP treatment were ascertained by diagnostic and procedural codes from the electronic health records. Sociodemographic characteristics and health service utilization factors were identified using self-reported survey data.

RESULTS

With this national survey, the overall diagnosed prevalence of OSA was 8.8 %, with rates of 8.12 % in non-Hispanic (NH) Black adults, 5.99 % in Hispanic adults, and 10.35 % in NH White adults. When comparing to NH White adults, Hispanic adults were less likely to receive CPAP treatment for OSA after adjusting for socioeconomic and demographic characteristics, access to and utilization of health services, and comorbidities such as obesity and having multiple chronic conditions (OR = 0.73, 95 % CI = 0.59,0.90), p < 0.01.

CONCLUSIONS

The rates of CPAP treatment among OSA patients are not consistent across racial and ethnic groups. Unequal access to health services based on residence may contribute to these differences. Interventions that target disparities in OSA diagnosis, access to treatment, and barriers in insurance coverage could potentially help reduce racial and ethnic differences in OSA diagnosis and management.

Identifying clusters of patient comorbidities associated with obstructive sleep apnea using electronic health records

STUDY OBJECTIVES

The objectives of this study were to understand the relative comorbidity burden of obstructive sleep apnea (OSA), determine whether these relationships were modified by sex or age, and identify patient subtypes defined by common comorbidities.

METHODS

Cases with OSA and noncases (controls) were defined using a validated electronic health record (EHR)-based phenotype and matched for age, sex, and time period of follow-up in the EHR. We compared prevalence of the 20 most common comorbidities between matched cases and controls using conditional logistic regression with and without controlling for body mass index. Latent class analysis was used to identify subtypes of OSA cases defined by combinations of these comorbidities.

RESULTS

In total, 60,586 OSA cases were matched to 60,586 controls (from 1,226,755 total controls). Patients with OSA were more likely to have each of the 20 most common comorbidities compared with controls, with odds ratios ranging from 3.1 to 30.8 in the full matched set and 1.3 to 10.2 after body mass index adjustment. Associations between OSA and these comorbidities were generally stronger in females and patients with younger age at diagnosis. We identified 5 distinct subgroups based on EHR-defined comorbidities: High Comorbidity Burden, Low Comorbidity Burden, Cardiovascular Comorbidities, Inflammatory Conditions and Less Obesity, and Inflammatory Conditions and Obesity.

CONCLUSIONS

Our study demonstrates the power of leveraging the EHR to understand the relative health burden of OSA, as well as heterogeneity in these relationships based on age and sex. In addition to enrichment for comorbidities, we identified 5 novel OSA subtypes defined by combinations of comorbidities in the EHR, which may be informative for understanding disease outcomes and improving prevention and clinical care. Overall, this study adds more evidence that OSA is heterogeneous and requires personalized management.

Sleep and follow-up characteristics of Hispanic patients: Insights from a comparative analysis with White patients in polysomnographic split-night studies

BACKGROUND

Limited attention has been given to exploring the efficacy of titration in split-night polysomnography (PSG) and the factors influencing adherence to continuous positive airway pressure (CPAP) therapy. This study aims to evaluate the severity of OSA and PSG parameters in HP compared to WP.

METHODS

Split-night PSG studies conducted on adults. Participants were categorized based on self-reported ethnicity as either HP or WP.

RESULTS

The study enrolled 50 WP (15 women, 35 men, mean age 60.5 ± 13.60 years, mean BMI 34.2 ± 7.48) and 45 HP (24 women, 21 men, mean age 54.9 ± 13.06 years, mean BMI 37.3 ± 7.88). HP exhibited a mean apnea-hypopnea index (AHI) of 51.1 ± 33.67, saturation nadir of 77.8 ± 10.19, and time spent with saturation <90% of 21.0 ± 26.93 min. In WP, the mean AHI was 39.2 ± 24.49, saturation nadir 81.6 ± 9.04, and time spent <90% was 10.4 ± 17.17 min. All observed differences were statistically significant (p < 0.05). Auto CPAP was prescribed to all patients, with adherence at 3-4 months being 75% ± 30 for HP, with a usage of 5.5 ± 2.2 h, and a residual AHI of 3 ± 3.5. In WP, adherence was 79% ± 30, usage was 5.9 ± 2.1 h, and residual AHI was 3.6 ± 6.2. None of these differences reached statistical significance. Among HP, 37% missed follow-up appointments compared to 12% of WP. More HP used full-face masks, while more WP preferred nasal masks.

CONCLUSIONS

HP exhibited significantly worse OSA parameters during the diagnostic phase of PSG compared to WP. HP had a significantly higher no-show percentage than WP. CPAP adherence and residual AHI were not statistically different, but more HP missed follow-up appointments than WP.

The lived experience of positive airway pressure therapy in patients with obstructive sleep apnea across the lifespan: a qualitative study

STUDY OBJECTIVES

Although treatment of obstructive sleep apnea (OSA) with positive airway pressure (PAP) therapy is effective, adherence is often poor. Understanding the patient perspective is needed to inform adherence-promoting interventions. This qualitative study assessed the experiences, preferences, facilitators, and barriers surrounding PAP therapy for the management of OSA in patients from adolescence to older adulthood.

METHODS

Eligible participants ages 19 and older were identified from administrative health care claims; adolescent participants ages 12-18 and their parents/caregivers were identified via electronic health records of a tertiary sleep specialty clinic at a large children's hospital. Forty English-speaking patients and 10 parents of adolescents diagnosed with OSA and prescribed PAP therapy completed semistructured 60-minute telephone interviews conducted by a trained facilitator. Common themes and illustrative quotes were identified.

RESULTS

Themes around OSA diagnosis, initiating OSA treatment, learning about OSA/PAP, decision to start PAP, PAP benefits and challenges, and reasons for nonadherence were identified. Participants suggested design and delivery changes to improve PAP devices. Issues unique to adolescents and their parents were discussed.

CONCLUSIONS

The unique perspectives of patients regarding PAP therapy should be taken into consideration when developing interventions to increase PAP adherence and improve clinical care. Based on identified themes, opportunities for intervention may exist at all stages of care, from diagnosis to treatment initiation. Involving partners, parents, and other caregivers in PAP therapy may be beneficial for optimizing adherence.

Discrimination Predicts Suboptimal Adherence to CPAP Treatment and Mediates Black-White Differences in Use

BACKGROUND

Although racial and ethnic differences in CPAP adherence for OSA are widely established, no studies have examined the influence of perceived racial discrimination on CPAP usage, to our knowledge.

RESEARCH QUESTION

(1) Do Black adults with OSA report experiencing greater amounts of discrimination than non-Hispanic White adults? (2) Is discrimination associated with poorer CPAP adherence over time, independent of self-identified race? (3) Does discrimination mediate the relationship between self-identified Black race and CPAP usage?

STUDY DESIGN AND METHODS

In this prospective study, Black and non-Hispanic White adults with OSA initiating CPAP were enrolled from two sleep centers and completed questionnaires including sociodemographics, perceived discrimination, daytime sleepiness, insomnia symptoms, and depressive symptoms. Perceived discrimination was measured using the Everyday Discrimination Scale (EDS). Black and White group comparisons for baseline sociodemographic variables, sleep symptoms, and perceived discrimination were performed with Student t test or χ2/Fisher exact test, as appropriate. A linear regression model was completed with self-identified Black race and EDS total score as the primary independent variables of interest and mean daily CPAP usage at 30 and 90 days serving as the dependent outcomes. This regression modeling was repeated after adjusting for psychosocial variables known to be associated with CPAP usage. EDS total score was explored as a potential mediator of the association between self-identified Black race and mean daily CPAP adherence at 30 and 90 days.

RESULTS

The sample for this analysis consisted of 78 participants (31% female, 38% Black) with a mean age of 57 ± 14 years. Sixty percent of the Black adults reported they experienced racial discrimination at least a few times each year. Relative to White adults, Black adults were also more likely to indicate more than one reason for discrimination (27% vs 4%, P = .003). Adjusting for discrimination, self-identified Black race was associated with 1.4 (95% CI, -2.3 to -0.4 h; P = .006) and 1.6 (95% CI, -2.6 to -0.6 h; P = .003) fewer hours of mean daily CPAP usage at 30 and 90 days, respectively. In the fully adjusted model, a 1-unit change in the total discrimination score (more discrimination) was associated with a 0.08-h (95% CI, 0.01-0.15 h; P = .029) and 0.08-h (95% CI, 0.01-0.16 h; P = .045) change in mean daily CPAP usage at 30 and 90 days, respectively.

INTERPRETATION

Adults with OSA who encountered racial discrimination experienced greater decrement in CPAP usage than those who did not experience racial discrimination.

CPAP resumption after a first termination and impact on all-cause mortality in France

BACKGROUND

Continuation of continuous positive airway pressure (CPAP) therapy after initial prescription has been shown to reduce all-cause mortality versus therapy termination. However, there is a lack of data on the rates and impact of resuming CPAP in patients with obstructive sleep apnoea (OSA). This analysis determined the prevalence of CPAP resumption in the year after termination, characterised determinants of CPAP resumption, and examined the impact of CPAP resumption on all-cause mortality.

METHODS

French national health insurance reimbursement system data for adults aged ≥18 years were used. CPAP prescription was identified by specific treatment codes. Patients who resumed CPAP after first therapy termination and continued to use CPAP for 1 year were matched with those who resumed CPAP then terminated therapy for a second time.

RESULTS

Out of 103 091 individuals with a first CPAP termination, 26% resumed CPAP over the next 12 months, and 65% of these were still using CPAP 1 year later. Significant predictors of CPAP continuation after resumption included male sex, hypertension and CPAP prescription by a pulmonologist. In the matched population, the risk of all-cause death was 38% lower in individuals who continued using CPAP after therapy resumption versus those who had a second therapy discontinuation (hazard ratio 0.62, 95% CI 0.48-0.79; p=0.0001).

CONCLUSION

These data suggest that individuals with OSA who fail initial therapy with CPAP should be offered a second trial with the device to ensure that effective therapy is not withheld from those who might benefit.

The effects of social support and support types on continuous positive airway pressure use after 1month of therapy among adults with obstructive sleep apnea

BACKGROUND

The relationship between perceived social support and continuous positive airway pressure remains understudied among individuals with obstructive sleep apnea. The aim of this prospective cohort study was to determine if baseline perceived social support and subtypes predict regular continuous positive airway pressure use after 1month of therapy.

METHODS

Adults with obstructive sleep apnea initiating continuous positive airway pressure therapy were recruited from sleep clinics in New York City. Demographics, medical history, and comorbidities were obtained from patient interview and review of medical records. Objective continuous positive airway pressure adherence data was collected at the first clinical follow-up.

RESULTS

Seventy-five participants (32% female; non-Hispanic Black 41%; mean age of 56 ± 14years) provided data. In adjusted analyses, poorer levels of overall social support, and subtypes including informational/emotional support, and positive social interactions were associated with lower continuous positive airway pressure use at 1month. Relative to patients reporting higher levels of support, participants endorsing lower levels of overall social support, positive social interaction and emotional/informational support had 1.6 hours (95% CI: 0.5,2.7, hours; p = .007), 1.3 hours (95% CI: 0.2,2.4; p = .026), and 1.2 hours (95% CI: 0.05,2.4; p = .041) lower mean daily continuous positive airway pressure use at 1month, respectively.

CONCLUSION

Focusing on social support overall and positive social interaction particularly, could be an effective approach to improve continuous positive airway pressure adherence in patients at risk of suboptimal adherence.

Predictors of Adherence to Continuous Positive Airway Pressure in Older Adults With Apnea and Amnestic Mild Cognitive Impairment

BACKGROUND

Almost 60% of adults with amnestic mild cognitive impairment (aMCI) have obstructive sleep apnea (OSA). Treatment with continuous positive airway pressure (CPAP) may delay cognitive decline, but CPAP adherence is often suboptimal. In this study, we report predictors of CPAP adherence in older adults with aMCI who have increased odds of progressing to dementia, particularly due to Alzheimer's disease.

METHODS

The data are from Memories 2, "Changing the Trajectory of Mild Cognitive Impairment with CPAP Treatment of Obstructive Sleep Apnea." Participants had moderate to severe OSA, were CPAP naïve, and received a telehealth CPAP adherence intervention. Linear and logistic regression models examined predictors.

RESULTS

The 174 participants (mean age 67.08 years, 80 female, 38 Black persons) had a mean apnea-hypopnea index of 34.78, and 73.6% were adherent, defined as an average of ≥4 hours of CPAP use per night. Only 18 (47.4%) Black persons were CPAP adherent. In linear models, White race, moderate OSA, and participation in the tailored CPAP adherence intervention were significantly associated with higher CPAP use at 3 months. In logistic models, White persons had 9.94 times the odds of adhering to CPAP compared to Black persons. Age, sex, ethnicity, education, body mass index, nighttime sleep duration, daytime sleepiness, and cognitive status were not significant predictors.

CONCLUSIONS

Older patients with aMCI have high CPAP adherence, suggesting that age and cognitive impairment should not be a barrier to prescribing CPAP. Research is needed to improve adherence in Black patients, perhaps through culturally tailored interventions.

Non-invasive ventilation usage and adherence in children and adults with Duchenne muscular dystrophy: A multicenter analysis

INTRODUCTION/AIMS

Non-invasive ventilation (NIV) is routinely prescribed to support the respiratory system in Duchenne muscular dystrophy (DMD) patients; however, factors improving NIV usage are unclear. We aimed to identify predictors of NIV adherence in DMD patients.

METHODS

This was a multicenter retrospective analysis of DMD patients prescribed NIV and followed at (1) The Hospital for Sick Children, Canada; (2) Rady Children's Hospital San Diego, USA; and (3) University of California San Diego Health, USA, between February 2016 and October 2020. The primary and secondary outcomes were 90-day period NIV adherence and clinical and socioeconomic predictors of NIV adherence.

RESULTS

We identified 59 DMD patients prescribed NIV (mean ± SD age = 20.1 ± 6.7 y). Overall, percentage of nights used, and average nightly usage, were 79.9 ± 31.1% and 7.23 ± 4.12 h, respectively. Compared with children, adults had higher percentage of nights used (92.9 ± 16.9% vs. 70.4 ± 36.9%; P < .05), and average nightly usage (9.5 ± 4.7 h vs. 5.3 ± 3.7 h; P < .05). Non-English language (P = .01), and absence of deflazacort prescription (P = .02) were significantly associated with higher percentage of nights used while Hispanic ethnicity (P = .01), low household income (P = .02), and absence of deflazacort prescription (P = .02) were significantly associated with higher nightly usage. Based on univariable analysis, older age and declining forced vital capacity were associated with increased percentage of nights used and increased average nightly usage.

DISCUSSION

Certain clinical and socioeconomic determinants had a significant impact on NIV adherence in DMD patients, providing insight into those at risk for high versus low compliance with respiratory therapy.

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.

Acceptability, adaptability and adherence to CPAP therapy among Aboriginal Australians with OSA - "The A5 study"

BACKGROUND

Studies examining how Australian Aboriginal people will accept, adapt and adhere to interventions such as continuous positive airway pressure (CPAP) therapy in the management of obstructive sleep apnoea (OSA) are sparsely reported.

METHODS

In this study, clinical, demographic, polysomnographic (PSG) and CPAP data were utilised to assess and predict acceptance and adherence to CPAP therapy among adult Aboriginal Australians diagnosed to have OSA.

RESULTS

Of the 649 Aboriginal patients with OSA, 49% accepted to trial CPAP therapy. Patients who accepted to trial CPAP showed more severe OSA (65vs.35% with severe OSA), reported higher daytime sleepiness (median 10vs.9), and had a higher BMI (83vs.73% obese). Of those who accepted to trial CPAP, 62% adapted to therapy (used the device for more than 30 days). Patients who adapted had more severe OSA (71vs.54% with severe OSA), and were more likely to live in urban areas (63vs.40%). Of those who adapted, 32% were adherent to therapy. Adherent patients were more likely to live in urban areas (84vs.53%), though there was no difference in OSA severity between adherent and non-adherent patients. In multivariate models remote location and more severe OSA predicted CPAP acceptance, while urban location and more severe OSA predicted adaptation, and urban location and higher oxygen saturation nadir predicted adherence.

CONCLUSIONS

Acceptance to trial CPAP therapy was observed in the presence of symptomatic and severe OSA. However, long term adherence to CPAP therapy was significantly influenced by patients' residential location, with patients residing in remote/rural settings demonstrating significantly lower adherence rates.

Moving toward Equitable Care for Sleep Apnea in the United States: Positive Airway Pressure Adherence Thresholds: An Official American Thoracic Society Policy Statement

Background: Positive airway pressure (PAP) is a highly effective treatment for obstructive sleep apnea (OSA), but adherence limits its efficacy. In addition, coverage of PAP by CMS (Centers for Medicare & Medicaid Services) and other insurers in the United States depends on adherence. This leaves many beneficiaries without PAP, disproportionally impacting non-white and low socioeconomic position patients with OSA and exacerbating sleep health disparities. Methods: An inter-professional, multidisciplinary, international committee with various stakeholders was formed. Three working groups (the historical policy origins, impact of current policy, and international PAP coverage models) met and performed literature reviews and discussions. Using surveys and an iterative discussion-based consensus process, the policy statement recommendations were created. Results: In this position paper, we advocate for policy change to CMS PAP coverage requirements to reduce inequities and align with patient-centered goals. We specifically call for eradicating repeat polysomnography, eliminating the 4-hour rule, and focusing on patient-oriented outcomes such as improved sleepiness and sleep quality. Conclusions: Modifications to the current policies for PAP insurance coverage could improve health disparities.

Racial Differences in Positive Airway Pressure Adherence in the Treatment of Sleep Apnea

Although data are limited, studies suggest on average lower positive airway pressure use in Black, indigenous, and people of color (BIPOC) compared with Whites in most but not all studies. Most of these observational studies are certainly limited by confounding by socioeconomic status and other unmeasured factors that likely contribute to differences. The etiology of these observed disparities is likely multifactorial, due in part to financial limitations, differences in sleep opportunity, poor sleep quality due to environmental disruptions, and so forth. These disparities in sleep health are likely related to chronic inequities, including experiences of racism, neighborhood features, structural, and contextual factors. Dedicated studies focusing on understanding adherence in BIPOC are lacking. Further research is needed to understand determinants of PAP use in BIPOC subjects and identify feasible interventions to improve sleep health and reduce sleep apnea treatment disparities.

Positive Airway Pressure Usage in Youth with Obstructive Sleep Apnea Following Transition to Adult Health Care

BACKGROUND

There is increasing prevalence of moderate to severe obstructive sleep apnea (OSA) in adolescents, the majority of whom receive treatment with positive airway pressure (PAP). Adherence to PAP is sub-optimal in adolescents with OSA. Moreover, the impact of transition from pediatric to adult healthcare system on PAP adherence is unknown. This is relevant as the transition period is a time of increased stress for youth with chronic illnesses.

RESEARCH QUESTION

Does PAP adherence decrease during the 1-year transition period from pediatric to adult healthcare system in those with OSA?

STUDY DESIGN AND METHODS

Youth previously diagnosed with persistent OSA and treated with PAP in a large academic center (Toronto, Canada) between 2017 and 2019 were enrolled on transfer from the pediatric to adult sleep clinic and followed at 12 months. Mixed-effects linear regression models were used to investigate the effect of time since the transfer on objective PAP adherence with adjustment for confounders.

RESULTS

Among the 45 enrolled participants, 42.2% were female, the median age was 18 years (interquartile range [IQR]: 17-18), median BMI was 30.3 (IQR: 24.0-37.1), and the median apnea-hypopnea index (AHI) was 17.8 events/hour (11.8-30.7). In univariate analysis, we observed a significant reduction in the 12-month average PAP usage in days used at follow-up compared to PAP use at the time of enrolment: median of 5.0 hours/day (IQR: 1.3-8.0) vs 2.6 hours/day (0.0-6.4), p < 0.0001. Following adjustment for age, level of education, employment status and living arrangement, the 12-month average PAP usage in days remained significantly decreased at follow-up compared to at the time of enrolment: change in hours of -1.14; 95% CI -2.27 to -0.01.

INTERPRETATION

Among youth with OSA treated with PAP, there is a clinically significant reduction in PAP adherence over the first year during the transition from pediatric to adult health care.

Incidence of insomnia and obstructive sleep apnea in active duty United States military service members

STUDY OBJECTIVES

Epidemiologic studies of obstructive sleep apnea (OSA) and insomnia in the U.S. military are limited. The primary aim of this study was to report and compare OSA and insomnia diagnoses in active duty the United States military service members.

METHOD

Data and service branch densities used to derive the expected rates of diagnoses on insomnia and OSA were drawn from the Defense Medical Epidemiology Database. Single sample chi-square goodness of fit tests and independent samples t-tests were conducted to address the aims of the study.

RESULTS

Between 2005 and 2019, incidence rates of OSA and insomnia increased from 11 to 333 and 6 to 272 (per 10,000), respectively. Service members in the Air Force, Navy, and Marines were diagnosed with insomnia and OSA below expected rates, while those in the Army had higher than expected rates (p < .001). Female service members were underdiagnosed in both disorders (p < .001). Comparison of diagnoses following the transition from ICD 9 to 10 codes revealed significant differences in the amounts of OSA diagnoses only (p < .05).

CONCLUSION

Since 2005, incidence rates of OSA and insomnia have markedly increased across all branches of the U.S. military. Despite similar requirements for overall physical and mental health and resilience, service members in the Army had higher rates of insomnia and OSA. This unexpected finding may relate to inherent differences in the branches of the military or the role of the Army in combat operations. Future studies utilizing military-specific data and directed interventions are required to reverse this negative trend.

Neighborhoods with Greater Prevalence of Minority Residents Have Lower Continuous Positive Airway Pressure Adherence

Rationale: Limited data suggest racial disparities in continuous positive airway pressure (CPAP) adherence exist.Objectives: To assess whether CPAP adherence varies by neighborhood racial composition at a national scale.Methods: Telemonitoring data from a CPAP manufacturer database were used to assess adherence in adult patients initiating CPAP therapy between November 2015 and October 2018. Mapping ZIP code to ZIP code tabulation areas, age- and sex-adjusted CPAP adherence data at a neighborhood level was computed as a function of neighborhood racial composition. Secondary analyses adjusted for neighborhood education and poverty.Measurements and Main Results: Among 787,236 patients living in 26,180 ZIP code tabulation areas, the prevalence of CPAP adherence was 1.3% (95% confidence interval [CI], 1.0-1.6%) lower in neighborhoods with high (⩾25%) versus low (<1%) percentages of Black residents and 1.2% (95% CI, 0.9-1.5%) lower in neighborhoods with high versus low percentages of Hispanic residents (P < 0.001 for both), even after adjusting for neighborhood differences in poverty and education. Mean CPAP usage was similar across neighborhoods for the first 2 days, but by 90 days, differences in CPAP usage increased to 22 minutes (95% CI, 18-27 min) between neighborhoods with high versus low percentages of Black residents and 22 minutes (95% CI 17-27 min) between neighborhoods with high versus low percentages of Hispanic residents (P < 0.001 for both).Conclusions: CPAP adherence is lower in neighborhoods with greater proportions of Black and Hispanic residents, independent of education or poverty. These differences lead to a lower likelihood of meeting insurance coverage requirements for CPAP therapy, potentially exacerbating sleep health disparities.

CPAP adherence is associated with reduced risk for stroke among older adult Medicare beneficiaries with obstructive sleep apnea

STUDY OBJECTIVES

To examine the impact of adherence to continuous positive airway pressure (CPAP) therapy on risk of stroke among a nationally representative sample of older adults with obstructive sleep apnea.

METHODS

We performed a retrospective cohort study among Medicare beneficiaries aged ≥ 65 years who were newly diagnosed with obstructive sleep apnea and had initiated CPAP (2009-2013). Monthly indicators of CPAP adherence included charges for machines, masks, or supplies and were summed over a 25-month follow-up to create a CPAP adherence variable. Stroke was modeled as a function of CPAP adherence using generalized estimating equations.

RESULTS

We found that 5,757 beneficiaries met the inclusion criteria and were included in the final sample. Of these, 407 (7%) experienced stroke. After adjusting for demographic and clinical characteristics, CPAP adherence was associated with a reduced risk of stroke (hazard ratio, 0.98; 95% confidence interval, 0.96-0.99) over 25 months, indicating a 2% reduction in risk of stroke for each month of CPAP adherence. When sensitivity analyses were performed to stratify results by time since the first CPAP charge, the protective effect remained significant for the 12- and 6-month but not the 3-month outcome models.

CONCLUSIONS

In this national analysis of older adult Medicare beneficiaries with obstructive sleep apnea, CPAP adherence was associated with significantly reduced risk of stroke.

Sleep Apnea and Insomnia: Emerging Evidence for Effective Clinical Management

Comorbid insomnia and sleep apnea (COMISA) are the most common co-occurring sleep disorders and present many challenges to clinicians. This review provides an overview of the clinical challenges in the management of patients with COMISA, with a focus on recent evidence regarding the evaluation and treatment of COMISA. Innovations in the assessment of COMISA have used profile analyses or dimensional approaches to examine symptom clusters or symptom severity that could be particularly useful in the assessment of COMISA. Recent randomized controlled trials have provided important evidence about the safety and effectiveness of a concomitant treatment approach to COMISA using cognitive-behavioral therapy for insomnia (CBT-I) with positive airway pressure (PAP). Furthermore, patient-centered considerations that integrate patient characteristics, treatment preferences, and accessibility to treatment in the context of COMISA are discussed as opportunities to improve patient care. Based on these recent advances and clinical perspectives, a model for using multidisciplinary, patient-centered care is recommended to optimize the clinical management of patients with COMISA.

Value-based sleep and breathing: health economic aspects of obstructive sleep apnea

Obstructive sleep apnea (OSA) is a common and costly medical condition. Untreated OSA is associated with numerous and well-documented adverse health consequences including depression, diabetes, cardiovascular disease, and premature death. In addition to these health consequences, untreated OSA is also associated with substantial costs borne by patients, payers, the health system, and society at large. Perhaps more importantly, evidence suggests that OSA treatment is associated with positive economic benefit. The purpose of this brief review is to introduce economic aspects of OSA, including the potential economic benefit of OSA treatment.

Socioeconomic Disparities in Positive Airway Pressure Adherence: An Integrative Review

Nonadherence with positive airway pressure (PAP) therapy impedes the effectiveness of treatment and increases risk of mortality. Disparities in PAP adherence as a function of socioeconomic status (SES) are not well understood. A literature search identified 16 original publications meeting inclusion criteria that described effects of SES factors on objective PAP adherence; 69% of these articles found evidence of lower adherence as a function of SES. This integrative review provides a structured summary of the findings, highlights factors that may contribute to disparities among adult PAP users, and identifies future directions to improve equity in the management of OSA.

CPAP adherence reduces cardiovascular risk among older adults with obstructive sleep apnea

STUDY OBJECTIVES

To examine (1) the impact of adherence to continuous positive airway pressure (CPAP) therapy on risk for cardiovascular (CVD) events among a nationally representative sample of older adults with obstructive sleep apnea (OSA), and (2) the heterogeneity of this effect across subgroups defined by race, sex, and socioeconomic status.

METHODS

We conducted a retrospective cohort study among Medicare beneficiaries aged ≥ 65 years with OSA (2009-2013). Monthly indicators of CPAP adherence (charges for machines, masks, or supplies) were summed over 25 months to create a CPAP adherence variable. New CVD events (ischemic heart disease, cardiac and peripheral procedures) were modeled as a function of CPAP adherence using generalized estimating equations. Heterogeneity of the effect of CPAP on new CVD events was evaluated based on race, sex, and socioeconomic status.

RESULTS

Among 5024 beneficiaries diagnosed with OSA who initiated CPAP, 1678 (33%) demonstrated new CVD events. Following adjustment for demographic and clinical characteristics, CPAP adherence was associated with reduced risk of new CVD events (hazard ratio 0.95; 95% confidence interval 0.94, 0.96) over 25 months. When analyses were stratified by time since the first CPAP charge, the protective effect remained significant for the 12- and 6-month, but not 3-month, outcome models. No significant differences were observed in the protective effect of CPAP based on race, sex, or socioeconomic status.

CONCLUSIONS

In this national study of older adult Medicare beneficiaries with OSA, CPAP adherence was associated with greatly reduced risk for CVD events. This risk reduction was consistent across race, sex, and socioeconomic subgroups.

Screening for Obstructive Sleep Apnea in a Diverse Bariatric Surgery Population

OBJECTIVE

Obstructive sleep apnea (OSA) is common among bariatric surgery patients and is associated with perioperative risk. Preoperative screening is recommended, but some screening tools lack validation, and their relative performance is unclear in this population. The study objective was to compare the ability of four existing tools (STOP-BANG, NO-OSAS, No-Apnea, and the Epworth Sleepiness Scale [ESS]) to screen for moderate to severe OSA in a diverse bariatric cohort.

METHODS

Data from patients presenting for first-time bariatric surgery who underwent a sleep study within 1 year of the initial encounter were retrospectively reviewed. Performance of the four tools for detecting moderate to severe OSA was compared based on the area under the receiver operating characteristic curves (AUC).

RESULTS

Of the included 214 patients (83.2% female, median age 39 years), 45.3% had moderate to severe OSA. Based on AUC, STOP-BANG (0.75 [95% CI: 0.68-0.81], N = 185), NO-OSAS (0.76 [95% CI: 0.69-0.82], N = 185), and No-Apnea (0.69 [95% CI: 0.62-0.76], N = 190) had similar performance (P > 0.16). Compared with STOP-BANG and NO-OSAS, ESS (0.61 [95% CI: 0.54-0.68], N = 198) had a significantly lower AUC (P < 0.01). Hispanic/Latino self-identification, sex, or obesity class did not significantly modify test performance.

CONCLUSIONS

STOP-BANG and NO-OSAS may be preferable to No-Apnea and ESS when screening bariatric surgery patients for moderate to severe OSA. Efforts to screen bariatric patients for OSA are recommended.

Utilization of surgical treatment for sleep apnea: A study of health disparities

OBJECTIVE

Barriers to surgical treatment for sleep apnea remain understudied. In this study, we sought to evaluate whether specific demographic and socioeconomic characteristics are associated with whether or not patients receive surgery for sleep apnea management.

METHODS

The National Inpatient Sample (NIS) database was analyzed for 2007-2014. Patients aged 18 or older with primary or secondary diagnoses of sleep apnea were selected. Patients were sub-categorized by whether they received related soft-tissue removal or skeletal modifying procedures. Age, race, gender, region, insurance, comorbidities, procedure type, and procedure setting were analyzed between surgical and nonsurgical groups.

RESULTS

A total of 449,705 patients with a primary or secondary diagnosis of sleep apnea were identified, with 27,841 (5.8%) receiving surgical intervention. Compared with the non-surgical group, patients in the surgical cohort were more likely to be younger, male (74.4% vs. 59.0%), Hispanic (10.2% vs. 6.2%), Asian (3.6% vs. 1.0%) (p < 0.001), and have less clinical comorbidities. Those receiving surgery were more likely to be in the highest income bracket (36.1% versus 25.1%) and utilize private insurance (76.3% vs. 50.8%). Soft-tissue surgeries comprised 88.5% of total procedures while skeletal modifying procedures constituted 11.5% (p < 0.001).

CONCLUSIONS

This study identified multiple demographic, socioeconomic, and clinical discrepancies in the utilization of surgical versus nonsurgical management of sleep apnea in the United States. Future studies should examine the causes for these health disparities in the ultimate effort to provide more equitable healthcare in the United States.

Pilot of Brief Health Coaching Intervention to Improve Adherence to Positive Airway Pressure Therapy

BACKGROUND

Adherence to positive airway pressure (PAP) therapies is poor, particularly among low-income populations and racial minorities. This study tested a low-resource, brief telephonic health coaching intervention to improve PAP adherence.

METHODS

Post hoc analysis of a quality improvement initiative in which English- and Spanish-speaking patients from a county-based public health system were randomly assigned to receive health coaching or usual care. An unlicensed, trained health coach called patients three times to resolve barriers to adherence. A per-protocol analysis was conducted for adherence measures collected by device modem at baseline and 30 days.

RESULTS

Of 131 people for whom device data were available, 56 were randomized to health coaching and 75 to usual care. At baseline, 47.3% of patients had used their device at any time in the past 30 days, with a mean of 2 hours of use per night. At 30 days, adjusting for baseline, patients in the coaching arm were more likely than usual care patients to use their device (55.4% vs. 41.3%, p = 0.03), and they increased their use for 0.4 hours over usual care (p = 0.04).

CONCLUSION

This pilot study suggests that a low-cost intervention could be effective at improving PAP adherence, even in a population known to have poor adherence and among long-term PAP users with poor adherence. Future research may examine whether a higher-touch intervention or one using videoconferencing yields greater improvements. This promising intervention warrants further study.

A randomized controlled trial of CBT-I and PAP for obstructive sleep apnea and comorbid insomnia: main outcomes from the MATRICS study

STUDY OBJECTIVES

To investigate treatment models using cognitive behavioral therapy for insomnia (CBT-I) and positive airway pressure (PAP) for people with obstructive sleep apnea (OSA) and comorbid insomnia.

METHODS

121 adults with OSA and comorbid insomnia were randomized to receive CBT-I followed by PAP, CBT-I concurrent with PAP, or PAP only. PAP was delivered following standard clinical procedures for in-lab titration and home setup and CBT-I was delivered in four individual sessions. The primary outcome measure was PAP adherence across the first 90 days, with regular PAP use (≥4 h on ≥70% of nights during a 30-day period) serving as the clinical endpoint. The secondary outcome measures were the Pittsburgh Sleep Quality Index (PSQI) and Insomnia Severity Index (ISI) with good sleeper (PSQI <5), remission (ISI <8), and response (ISI reduction from baseline >7) serving as the clinical endpoints.

RESULTS

No significant differences were found between the concomitant treatment arms and PAP only on PAP adherence measures, including the percentage of participants who met the clinical endpoint. Compared to PAP alone, the concomitant treatment arms reported a significantly greater reduction from baseline on the ISI (p = .0009) and had a greater percentage of participants who were good sleepers (p = .044) and remitters (p = .008). No significant differences were found between the sequential and concurrent treatment models on any outcome measure.

CONCLUSIONS

The findings from this study indicate that combining CBT-I with PAP is superior to PAP alone on insomnia outcomes but does not significantly improve adherence to PAP.

Obstructive sleep apnea treatment disparities among older adults with neurological disorders

OBJECTIVE

The objective of the study was to characterize obstructive sleep apnea treatment patterns among older Americans with neurological conditions.

SETTING AND PARTICIPANTS

Claims data from a 5% fee-for-service sample of Medicare beneficiaries were analyzed to determine the proportion of older adults with OSA who received and were adherent to continuous positive airway pressure therapy and examine potential gaps in OSA care among neurological populations. Logistic regression was used to determine whether gender or race/ethnicity modified the associations between neurological morbidities and OSA treatment or adherence.

RESULTS

Data from n = 102,618 beneficiaries with OSA were identified. The prevalence of stroke, cognitive disorders, or Parkinson's disease in this sample was 7%, 3%, and 2% respectively. Overall, OSA-diagnosed individuals (73%) obtained treatment, and most treated were adherent to CPAP (72%). Lower proportions of OSA treatment and adherence were observed in neurological conditions, particularly stroke. In logistic regression models, gender and race/ethnicity each modified associations between neurological comorbidity and OSA treatment and adherence. Women as compared to men with a given neurological condition were uniformly less likely to receive CPAP or adhere to treatment (P < .01 for each condition). Similarly, in comparison to whites with the same neurological condition, OSA treatment was significantly lower among all other races with stroke, and among blacks with cognitive disorders.

CONCLUSIONS

Older women and minorities with neurological conditions may be more vulnerable to gaps in OSA care. Targeted strategies to improve treatment disparities and neurological outcomes in older adults could be informed by these data.

Sleep disorders in migrants and refugees: a systematic review with implications for personalized medical approach

Background

Sleep disorders are very common in migrants and refugees, often as a comorbid disorder to different somatic or psychiatric diagnoses and psychological disturbances such as metabolic syndrome, post-traumatic stress disorder, depression, and anxiety disorders.

Objectives

To review published prevalence rates as well as possible predictors for sleep disturbances in these vulnerable groups, including pre-migration stress, acculturation, and trauma before, during, and after migration, integration, and lifestyle in the host country with implications for predictive, preventive, and personalized medical approach (3PM).

Data sources

Electronic databases PubMed, PsycInfo, and Web of Knowledge were searched using (combined) search terms "migrant," "asylum seeker," "refugee," "sleep disturbances," "sleep disorder," "insomnia," and "sleep wake disorder."

Study eligibility criteria

Peer-reviewed studies from 2000 to 2018 reporting data on prevalence and/or predictors of any measure of sleep disturbance were included.

Participants

Studies on international migrants and refugees, as well as internally displaced populations, were included.

Methods

We conducted a systematic review on the topic of sleep disorders in migrant and refugee populations. Only published articles and reviews in peer-reviewed journals were included.

Results

We analyzed five studies on sleep disorders in migrants, five studies on adult refugees, and three on refugee children and adolescents. Prevalence of sleep disorders in migrants and refugees ranges between 39 and 99%. In migrant workers, stress related to integration and adaptation to the host society is connected to higher risks of snoring, metabolic diseases, and insomnia. Sleep disturbances in refugees are predicted by past war experience. Sleep difficulties in adult and child refugees are strongly correlated to trauma. Torture of parents and grandparents can predict sleep disorders in refugee children, while being accompanied by parents to the host country has a protective effect on children's sleep.

Conclusions and implications

Considering the differences in risk factors, vulnerability, and traumatic life events for different migrant populations, origins of sleep difficulties vary, depending on the migrant populations. Effects on sleep disturbances and sleep quality may be a result of integration in the host country, including changes of lifestyle, such as diet and working hours with implication for OSAS (obstructive sleep apnea) and insomnia. Compared with migrant populations, sleep disturbances in refugee populations are more correlated with mental health symptoms and disorders, especially PTSD (post-traumatic stress disorder), than with psychosocial problems. In juvenile refugee populations, psychological problems and disturbed sleep are associated with traumatic experiences during their journey to the host country. Findings highlight the need for expert recommendations for development of 3P approach stratified in the following: (1) prediction, including structured exploration of predisposing and precipitating factors that may trigger acute insomnia, screening of the according sleep disorders by validated translated questionnaires and sleep diaries, and a face-to-face or virtual setting and screening of OSAS; (2) target prevention by sleep health education for female and male refugees and migrant workers, including shift workers; and (3) personalized medical approach, including translated cognitive behavioral treatment for insomnia (CBT-I) and imagery rehearsal therapy for refugees and telehealth programs for improved CPAP adherence in migrants, with the goal to enable better sleep health quality and improved health economy.

Developing a Tailored Website for Promoting Awareness about Obstructive Sleep Apnea (OSA) Among Blacks in Community-Based Settings

Blacks are at greater risk for lower sleep quality and higher risk for obstructive sleep apnea (OSA) than other racial groups. In this study, we summarize the development of a tailored website including visuals, key messages, and video narratives, to promote awareness about sleep apnea among community-dwelling blacks. We utilized mixed methods, including in-depth interviews, usability-testing procedures, and brief surveys (n = 9, 55% female, 100% black, average age 38.5 years). Themes from the qualitative analysis illuminated varied knowledge regarding OSA symptoms and prevalent self-reported experience with sleep disturbance and OSA symptoms (e.g., snoring). On a scale from 1 (not at all) to 5 (very high), participants provided favorable ratings of website usefulness (mean = 4.9), user friendliness (mean = 4.9) and attractiveness (mean = 4.3). Our findings suggest although tailored health communication has potential for serving as a tool for advancing health equity, usability-testing of health materials is critical to ensure that culturally and linguistically tailored messages are acceptable and actionable in the intended population.

Comorbidities associated with obstructive sleep apnea: a retrospective Egyptian study on 244 patients

PURPOSE

The aim of the present study was to assess prevalence of associated comorbidities in a group of patients diagnosed with obstructive sleep apnea syndrome (OSAS).

METHODS

This retrospective study enrolled 244 consecutive patients diagnosed by polysomnogram with OSAS between October 2010 and January 2015 after being referred to our Sleep-Related Breathing Disorders Unit, Chest Diseases Department, in the Alexandria Main University Hospital.

RESULTS

Of 244 patients, 47% were men, mean age was 56.9 years, and mean apnea-hypopnea index was 43.6 events per hour. Patients were categorized into two groups: group 1 (38%), mild and moderate OSAS, and group 2 (62%), severe, very severe, and extreme OSAS. Comorbidities were present in 91% of patients. The most common comorbidities were obesity, hypertension (HTN), and diabetes mellitus (DM). Prevalence of obesity, HTN, DM, congestive heart failure, deep vein thrombosis, pulmonary embolism (PE), and hypothyroidism was significantly higher in severity group 2. PE, bronchial asthma, and chronic obstructive pulmonary disease were significantly higher among men, whereas hypothyroidism was significantly higher among women. During this period of over 4 years, mortality rate was 8%. The majority of deaths occurred at night. Most of the studied patients (60%) either received no treatment or were not adherent to positive airway pressure (PAP) therapy. None of the patients received surgicaltreatment. The majority (50%) gained access to PAP therapy through donations. Associated hypoventilation was the only significant predictor of PAP adherence. Quality of life was significantly better among PAP adherent patients.

CONCLUSIONS

Patients suffering from OSAS have very high prevalence of comorbidities indicating a great burden on the healthcare system. Despite this fact, over 50% of the patients studied did not receive any treatment. Charities were the main portal fortreatment.

The Effect of Sleeping Environment and Sleeping Location Change on Positive Airway Pressure Adherence

STUDY OBJECTIVES

Poor adherence undermines the effectiveness of positive airway pressure (PAP) therapy for sleep apnea. Disparities exist in PAP adherence by race/ethnicity and neighborhood socioeconomic status (SES), but the etiology of these differences is poorly understood. We investigated whether home environmental factors contribute to PAP adherence and whether identified factors explain disparities in adherence by SES.

METHODS

Adult patients with sleep apnea were surveyed at clinic visits about their sleep environment. Medical records were abstracted for demographic data, sleep apnea severity, comorbidities, and objective PAP adherence. We evaluated the association between aspects of home sleep environment with PAP adherence using multivariate linear and logistic regression, and assessed effect modification by SES factors.

RESULTS

Participants (n = 119) were diverse, with 44% nonwhite and 35% uninsured/Medicaid. After adjusting for age, sex, race/ethnicity, insurance, neighborhood SES, education, and marital status, participants who endorsed changing sleeping location once per month or more (18%, n = 21) had 77% lower odds of meeting PAP adherence criteria (> 4 h/night for 70% of nights) and less PAP use (median -11 d/mo, 95% confidence intervals -15.3, -6.5). Frequency of sleeping location change was the only environmental factor surveyed associated with PAP adherence.

CONCLUSIONS

Frequent change in sleeping location is associated with reduced PAP adherence, independent of sociodemographic factors. This novel finding has implications for physician-patient dialogue. PAP portability considerations in device selection and design may modify adherence and potentially improve treatment outcomes. Prospective investigation is needed to confirm this finding and inform design of possible interventions.
