Lykouras D, Zarkadi E, Koulousousa E, Lagiou O, Komninos D, Tzouvelekis A, Karkoulias K. Factors Affecting CPAP Adherence in an OSA Population during the First Two Years of the COVID-19 Pandemic. Healthcare (Basel) 2024; 12:1772. [PMID: 39273796 PMCID: PMC11395159 DOI: 10.3390/healthcare12171772] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2024] [Revised: 08/31/2024] [Accepted: 09/02/2024] [Indexed: 09/15/2024] Open
Abstract
Background: Obstructive sleep apnea (OSA) is a common disorder associated with major cardiovascular and neurocognitive sequelae. Continuous positive airway pressure (CPAP) is the standard treatment for OSA. The aim of this study was to investigate the prevalence and associations of long-term CPAP adherence in newly diagnosed OSA patients. Methods: We enrolled patients who were diagnosed with OSA during the COVID-19 pandemic. Adherence was defined as CPAP use ≥4 h per night on ≥70% of nights over 30 consecutive days. Patient demographics were retrieved from medical records, and CPAP adherence at 6 months and 1 year after initiation was monitored. Results: Overall, 107 patients were included in the analysis. A number of 73 (68%) and 63 (59%) patients were adherent to CPAP treatment at 6 months and 12 months accordingly. Among the factors examined and analyzed (age, gender, BMI, Apnea-Hypopnea Index (AHI)), no significant correlation was found. Further analysis revealed the potential role of comorbidities. CPAP compliance at 6 months was shown to be associated with better CPAP adherence at 12 months. Conclusions: CPAP adherence at 6 months is correlated to long-term adherence to treatment. Therefore, early close follow-up is important. Further prospective studies are needed to identify other potential predictors.

Cost-effectiveness analysis of continuous positive airway pressure treatment for obstructive sleep apnea in Singapore from a health system perspective. J Sleep Res 2024:e14326.

Abstract
This study assessed the cost-effectiveness of continuous positive airway pressure treatment for obstructive sleep apnea in Singapore from a health system perspective. The analysis evaluated a 5-year care pathway using a Markov model, considering per-patient costs of treatment, health system cost savings of obstructive sleep apnea and attributed conditions, the effectiveness measured in disability-adjusted life years with a discount rate of 3% and a weighted 5-year continuous positive airway pressure adherence of 74.1% from Singapore studies. Per-patient costs of treatment were from a large public hospital in Singapore. Efficacy of continuous positive airway pressure treatment, health system costs and disability-adjusted life years were obtained from literature; costs are in US dollars. We conducted probabilistic sensitivity analysis, one-way sensitivity analysis and what-if analysis. Based on a willingness-to-pay threshold of US $50,000 per disability-adjusted life year in USA, continuous positive airway pressure therapy was highly cost-effective, with an incremental cost-effectiveness ratio of $13,822 per disability-adjusted life year averted. Compared with the annual total costs of $856 for patients with continuous positive airway pressure treatment diagnosed by an inpatient sleep study, the total costs for those diagnosed by a home sleep test were $625, resulting in a remarkable 27% reduction per patient per year. One-way sensitivity analysis indicated that costs of treatment, effectiveness of continuous positive airway pressure treatment and adherence had a higher impact on the cost-effectiveness of continuous positive airway pressure therapy. The what-if analysis suggested that for continuous positive airway pressure treatment to be cost-effective, adherence rate should be at least 16.1%. These findings provide valuable insights for policymakers in making informed decisions on funding diagnosis and continuous positive airway pressure therapy within Singapore's healthcare system.

Abstract
STUDY OBJECTIVES Considerable disparities in the prevalence, diagnosis, and management of obstructive sleep apnea (OSA) exist for minority groups in the United States. However, the impact of OSA on Native Hawaiian/Pacific Islanders (NHPIs) has not been evaluated. METHODS We performed a retrospective review of patient records of NHPIs who underwent sleep apnea testing between 2014 and 2021 at a single center in Utah to characterize the distribution of comorbidities, disease severity, and treatment adherence. RESULTS 140 of 141 NHPI patients who underwent sleep testing had OSA. High rates of obesity (94%) and other relevant comorbidities were found. OSA was mostly severe (57%), particularly in males with higher obesity. Adherence to continuous positive airway pressure was low (41% using for 4 or more hours on 70% of nights), and medical factors predicted whether adherence targets were met with modest accuracy (area under the curve 0.699). CONCLUSIONS NHPIs at a single sleep center had a high prevalence of comorbidities in association with OSA, a skewed distribution toward severe disease suggestive of barriers to care or unique disease characteristics, and low adherence to continuous positive airway pressure. These findings suggest a high burden of OSA in this population, and further work to characterize barriers to identifying and treating OSA in NHPIs can improve chronic disease outcomes in NHPIs.

Abstract
OBJECTIVES To determine factors that are associated with OSA therapy outcomes with auto-titrating positive airway pressure (APAP). METHODS We sequentially grouped patients from a retrospective cohort based on APAP efficacy (sufficiently vs. insufficiently treated; insufficiently treatment defined as residual AHI of ≥ 5), therapy adherence (adherent vs. non-adherent, non-adherence defined as < 70% usage for ≥ 4 h/night), and therapy outcomes (optimal vs. non-optimal and non-optimal outcomes defined as non-adherent and/or insufficiently treated). We subsequently compared each group. RESULTS The insufficiently treated were older (68.4 ± 12.5 vs. 60.4 ± 13.1 years, p < 0.01) and had lower BMI (31.9 ± 6.3 vs. 37.9 ± 9.1 kg/m2, p < 0.01). They had higher baseline central apnea indices (CAI), longer leaks, higher peak pressures, and were less compliant. The non-adherent were younger (61.1 ± 12.6 vs. 65.5 ± 13.2 years, p = 0.03) and comprised more females (56.1 vs. 43.9%, p = 0.04). The leak duration per usage hour was higher in the non-compliant (median: 1.5; IQR 7.9 vs. median: 0.3; IQR 1.9 min/h; p < 0.01). The non-optimally treated had lower BMI, longer leaks, and less nightly usage. Multivariate analyses showed that leak duration was the common factor associated with treatment effectiveness and optimal therapy outcomes. CONCLUSIONS Various demographic and clinical factors were associated with treatment efficacy and adherence. However, leak duration was the common factor related to treatment efficacy and overall optimal therapy outcomes.

Abstract
Introduction The benefits of CPAP in patients with obstructive sleep apnea (OSA) are not achieved without therapeutic adherence (TA). The perception of benefit is one of the main predictors of adherence. However, it is unknown whether the impact of CPAP on health-related quality of life (HRQoL) is related to TA. Objective 1) To evaluate whether changes in HRQoL after initiating CPAP are associated with AT. 2) To analyze the influence of various TA determinants, including baseline HRQoL. Methods Prospective observational and longitudinal study on a cohort of patients with moderate-severe OSA and indication of CPAP. Baseline and after-therapy HRQoL were evaluated using the Quebec Sleep Questionnaire (QSQ), as well as other possible AT determinants. A multivariate analysis was performed. Results A total of 364 patients (78% men) were included, with mean age of 55 ± 11 years and apnea-hypopnea index of 42 ± 19/hour. 33.3% without TA. There was no association between HRQoL changes after 3 months of CPAP and AT and between QSQ baseline score and AT. A higher ODI4%, a global improvement and social interactions (QSQ), were associated with AT. Baseline anxiety-depressive symptoms, worsening anxiety, and side effects with CPAP were associated with worse AT. Conclusions The impact of CPAP on HRQoL with respect to the perception of social interactions seems to condition TA. The basal impact of the disease, in terms of HRQoL, is not associated with AT.

Abstract
Background: The effectiveness of positive airway pressure therapies (PAP) is contingent on treatment adherence. We hypothesized that forgoing healthcare may be a determinant of adherence to PAP therapy. Research Question: The objectives were: (i) to assess the impact of forgoing healthcare on adherence to PAP in patients with Chronic Respiratory Failure (CRF) and patients with Obstructive Sleep Apnea Syndrome (OSAS); (ii) to compare forgoing healthcare patterns in these two chronic conditions. Study design and methods: Prospective cohort of patients with OSAS or CRF, treated with PAP therapies at home for at least 12 months. At inclusion, patients were asked to fill-in questionnaires investigating (i) healthcare forgone, (ii) deprivation (EPICES score), (iii) socio-professional and familial status. Characteristics at inclusion were extracted from medical records. PAP adherence was collected from the device's built-in time counters. Multivariable logistic regression models were used to assess the associations between healthcare forgone and the risk of being non-adherent to CPAP treatment. Results: Among 298 patients included (294 analyzed); 33.7% reported forgoing healthcare. Deprivation (EPICES score > 30) was independently associated with the risk of non-adherence (OR = 3.57, 95%CI [1.12; 11.37]). Forgoing healthcare had an additional effect on the risk of non-adherence among deprived patients (OR = 7.74, 95%CI [2.59; 23.12]). OSAS patients mainly forwent healthcare for financial reasons (49% vs. 12.5% in CRF group), whereas CRF patients forwent healthcare due to lack of mobility (25%, vs. 5.9 % in OSAS group). Interpretation: Forgoing healthcare contributes to the risk of PAP non-adherence particularly among deprived patients. Measures tailored to tackle forgoing healthcare may improve the overall quality of care in PAP therapies. Clinical Trial Registration: The study protocol was registered in ClinicalTrials.gov, identifier: NCT03591250.

Abstract
Although good adherence to continuous positive airway pressure (PAP) traditionally is defined as greater than or equal to 4 hours/night, the origins and rationale for this remain unclear. Research studies report variation in optimal duration of PAP adherence, depending on outcome of interest. Evidence demonstrates benefit with PAP for daytime sleepiness, quality of life, neurocognitive outcomes, depression, and hypertension, predominantly in symptomatic, moderate-severe obstructive sleep apnea. Recent randomized controlled trials, however, have failed to demonstrate a reduction in cardiovascular and mortality risks. This review explores the question of what can be considered a clinically meaningful outcome for PAP adherence.

Abstract
Objective Untreated obstructive sleep apnea syndrome (OSAS) increases the risk of cardiovascular, dementia, and motor vehicle accident events. However, continuous positive airway pressure (CPAP) which is the gold standard treatment is not acceptable for many patients with OSAS. Development of devices for the patients of nonadherence to CPAP is necessary. Materials and Methods We evaluated the effect of the smart antisnore pillow (SAP) in patients with OSAS in a prospective, noncontrolled, nonrandomized, pilot study. According to the apnea-hypopnea index (AHI), they were divided into two groups: mild-to-moderate OSAS group and severe OSAS group. Single-night polysomnography (PSG) with application of a SAP was performed. Thirty patients, 15 males and 15 females, 33–82 years old (mean age, 59.3 ± 12.9 years), completed the smart antisnore pillow therapy test. Among them, 23 patients had mild-to-moderate OSAS. Results The SAP significantly improved the snore number (p = 0.018), snore index (p = 0.013), oxygen denaturation index (p = 0.001), total AHI (p = 0.002), and supine AHI (p = 0.002) in the mild-to-moderate OSAS group, but there was no significant improvement in the severe OSAS group. Conclusions We concluded that the SAP is an effective positional therapy device for patients with OSAS of mild-to-moderate severity.

Abstract
The high burden of obstructive sleep apnea (OSA), combined with inadequate supply of sleep specialists and constraints on polysomnography resources, has prompted interest in alternative models of care to improve access and treatment effectiveness. In appropriately selected patients, ambulatory clinical pathways and use of nonphysicians or primary care providers to manage OSA can improve timely access and costs without compromising adherence or other clinical outcomes. Although initial studies show promising results, there are several potential barriers that must be considered before broad implementation, and further implementation research and economic evaluation studies are required.

Abstract
OBJECTIVES We describe drug-induced sleep endoscopy (DISE) obstruction patterns in adults with obstructive sleep apnea (OSA) based on body mass index (BMI). We also evaluate subgroups of patients with clinically significant obstruction patterns at the velopharynx and oropharynx. STUDY DESIGN Retrospective chart review. METHODS Single-institution, retrospective chart review of adults with OSA who underwent DISE with dexmedetomidine sedation from 2016 to 2018. Endoscopic findings were graded using VOTE (Velum, Oropharynx, Tongue base, Epiglottis) classification. Oropharyngeal obstruction was additionally graded with the modifier T when due to palatine tonsil tissue. Findings in patients who had BMI < 25, 25 ≤ BMI < 30, and BMI ≥ 30 were compared. RESULTS One hundred and eleven patients (1 underweight, 23 normal weight, 56 overweight, and 31 obese) were reviewed. Patients with lower BMI were more likely to have more severe obstruction at the level of the tongue base (χ2 = 11.52, P = .021) and epiglottis (χ 2 = 10.56, P = .032). Conversely, patients with higher BMI were more likely to have complete concentric (grade 2C) velum obstruction (χ 2 = 16.04, P < .001) and more severe oropharyngeal obstruction (χ 2 = 9.65, P = .046). Patients with grade 2 oropharyngeal obstruction without tonsil obstruction had more severe concurrent velum obstruction compared to subjects with grade 2 T oropharyngeal obstruction (P = .009). CONCLUSION In adults with OSA, BMI categories have significantly distinct obstruction patterns at all airway levels on DISE, and there appear to be distinct subgroups associated with certain velum and oropharynx collapse patterns. These findings may have important implications for positive airway pressure-alternative treatment. LEVEL OF EVIDENCE 3 Laryngoscope, 131:224-229, 2021.

Abstract
BACKGROUND Obstructive sleep apnea (OSA) is prevalent among bariatric surgery candidates and is associated with numerous adverse health conditions, both pre- and postoperatively. Continuous positive airway pressure therapy (CPAP) is the first-line treatment for OSA, but it requires significant behavioral changes. As such, CPAP adherence is a significant problem in OSA treatment. Information from the preoperative psychological evaluation may be used to identify psychosocial risk factors associated with CPAP nonadherence and inform the implementation of more specific and appropriate interventions. OBJECTIVES Examine the utility of Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) behavioral/externalizing dysfunction scale scores to determine personality and psychopathology associations with, and risk for, CPAP nonadherence. SETTING Academic medical center. METHODS Patients who underwent a preoperative psychological evaluation and were diagnosed with OSA (n = 358) were divided into 2 groups: CPAP adherent (n = 271) and CPAP nonadherent (n = 87). Independent samples t tests were computed to examine differences in average MMPI-2-RF scale scores between these groups. Relative risk ratios were computed using multiple MMPI-2-RF substantive scale score cut-offs to determine which MMPI-2-RF scales were associated with increased risk of CPAP nonadherence. RESULTS Higher scores on scales measuring behavioral/externalizing dysfunction and family problems were associated with and indicative of risk for CPAP nonadherence. CONCLUSIONS CPAP nonadherence is related to and may be affected by generally higher levels of behavioral/externalizing dysfunction. Using a broadband measure of personality and psychopathology, like the MMPI-2-RF, during the preoperative evaluation can provide important information about co-morbid symptoms that may interfere with CPAP adherence. Considering this information during preoperative treatment planning could increase the likelihood of preoperative CPAP adherence and reduce the likelihood of adverse postoperative outcomes.

Abstract
This critical review focuses on obstructive sleep apnea (OSA) and its management from a dental medicine perspective. OSA is characterized by ≥10-s cessation of breathing (apnea) or reduction in airflow (hypopnea) ≥5 times per hour with a drop in oxygen and/or rise in carbon dioxide. It can be associated with sleepiness and fatigue, impaired mood and cognition, cardiometabolic complications, and risk for transportation and work accidents. Although sleep apnea is diagnosed by a sleep physician, its management is interdisciplinary. The dentist’s role includes 1) screening patients for OSA risk factors (e.g., retrognathia, high arched palate, enlarged tonsils or tongue, enlarged tori, high Mallampati score, poor sleep, supine sleep position, obesity, hypertension, morning headache or orofacial pain, bruxism); 2) referring to an appropriate health professional as indicated; and 3) providing oral appliance therapy followed by regular dental and sleep medical follow-up. In addition to the device features and provider expertise, anatomic, behavioral, demographic, and neurophysiologic characteristics can influence oral appliance effectiveness in managing OSA. Therefore, OSA treatment should be tailored to each patient individually. This review highlights some of the putative action mechanisms related to oral appliance effectiveness and proposes future research directions.

Abstract
AbstractStudy ObjectivesPoor adherence to continuous positive airway pressure (CPAP) commonly affects therapeutic response in obstructive sleep apnea (OSA). We aimed to determine predictors of adherence to CPAP among participants of the Sleep Apnea and cardioVascular Endpoints (SAVE) trial.MethodsSAVE was an international, randomized, open trial of CPAP plus usual care versus usual care (UC) alone in participants (45–75 years) with co-occurring moderate-to-severe OSA (≥12 episodes/h of ≥4% oxygen desaturation) and established cardiovascular (CV) disease. Baseline sociodemographic, health and lifestyle factors, OSA symptoms, and 1-month change in daytime sleepiness, as well as CPAP side effects and adherence (during sham screening, titration week, and in the first month), were entered in univariate linear regression analyses to identify predictors of CPAP adherence at 24 months. Variables with p <0.2 were assessed for inclusion in a multivariate linear mixed model with country, age, and sex included a priori and site as a random effect.ResultsSignificant univariate predictors of adherence at 24 months in 1,121 participants included: early adherence measures, improvement in daytime sleepiness at 1 month, fixed CPAP pressure, some measures of OSA severity, cardiovascular disease history, breathing pauses, and very loud snoring. While observed adherence varied between countries, adherence during sham screening, initial titration, and the first month of treatment retained independent predictive value in the multivariate model along with fixed CPAP pressure and very loud snoring.ConclusionsEarly CPAP adherence had the greatest predictive value for identifying those at highest risk of non-adherence to long-term CPAP therapy.Clinical Trial RegistrationSAVE is registered with clinicaltrials.gov (NCT00738179).

Abstract
STUDY OBJECTIVES Self-reported sleepiness is common in patients with obstructive sleep apnea (OSA) and is being increasingly recognized as an effect modifier of the association between OSA and cardiovascular outcomes. However, data on whether sleepiness modifies the association between OSA and glycemic outcomes are lacking. The current study sought to characterize the association between glycemic control and sleepiness in people with OSA and type 2 diabetes. METHODS Adults with non-insulin requiring type 2 diabetes and undiagnosed moderate to severe OSA were recruited from the community. Demographic data, Epworth Sleepiness Scale (ESS), hemoglobin A1c (HbA1c), as well a type III home sleep test were obtained. The association between self-reported sleepiness and glycemic control was examined using quantile regression. RESULTS The study cohort included 311 participants with 56% of the sample being men. Stratified analyses by sex demonstrated that self-reported sleepiness was associated with a higher HbA1c level, but this association was present only in men with a body mass index (BMI) < 35 kg/m2. Mean HbA1c levels were higher by 0.57% (95% confidence interval: 0.11, 1.02) in men with an ESS ≥ 11 compared to men with an ESS < 11. No such association was observed in men with a BMI ≥ 35 kg/m2 or in women of any BMI category. CONCLUSIONS The association between self-reported sleepiness and glycemic control in people with type 2 diabetes and moderate to severe OSA varies a function of BMI and sex. The noted differences in association should be considered when assessing possible treatment effects of therapy for OSA on metabolic outcomes.

Predictors of CPAP adherence following stroke and transient ischemic attack. Sleep Med 2018; 66:243-249.

Abstract
OBJECTIVE Continuous positive airway pressure (CPAP) has been shown to improve functional, motor and cognitive outcomes in post-stroke obstructive sleep apnea (OSA). However, rates of CPAP adherence are often low and factors impacting CPAP adherence remain under-explored. Our objective was to determine predictors of CPAP adherence in patients who had a stroke or transient ischemic attack (TIA). METHODS We screened 313 stroke/TIA patients for OSA using in-hospital polysomnography or the ApneaLink home sleep apnea test. Potential predictors were recorded at baseline and adherence to CPAP was recorded during a six-month follow-up visit. Selected variables from our univariate analyses were included in multivariate regression models to determine predictors of CPAP adherence. For our logistic regression analyses, CPAP adherence (CPAP use of ≥4 h per night) was the dependent outcome variable. In our linear regression analyses, total CPAP use per week (recorded in hours) was the dependent outcome variable. RESULTS Eighty-eight patients (mean age 67.81 ± 13.09 years, 69.32% male, mean body mass index 27.93 ± 5.23 kg/m2) were diagnosed with OSA, prescribed CPAP, and assessed for adherence at a six-month follow-up visit. In these 88 patients, 46 (52.27%) were adherent with CPAP therapy. From our regression models, two significant predictors of CPAP adherence were identified: greater functional status (p = 0.04) and not endorsing daytime tiredness (p = 0.047) post-stroke/TIA. CONCLUSION Patients with greater functional capacity and those with less daytime fatigue demonstrated stronger adherence to CPAP therapy. Our findings may facilitate future treatment strategies for enhancing CPAP adherence in the vulnerable stroke/TIA population.

Factors influencing adherence to continuous positive airway pressure treatment in obstructive sleep apnea and mortality associated with treatment failure - a national registry-based cohort study. Sleep Med 2018; 51:85-91. [PMID: 30103074 DOI: 10.1016/j.sleep.2018.07.007] [Citation(s) in RCA: 36] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2018] [Revised: 06/21/2018] [Accepted: 07/05/2018] [Indexed: 10/28/2022]
Abstract
OBJECTIVES Adherence to continuous positive airway pressure (CPAP) in patients with obstructive sleep apnea (OSA) is crucial. Our aim was to identify protective and risk factors against the discontinuation of CPAP treatment in patients with OSA and to estimate the mortality risk in those who were non-adherent to CPAP therapy. METHODS This was a registry-based cohort study from 37 centers across Sweden with OSA patients on CPAP in the Swedevox Swedish national registry between July 2010 and March 2017. RESULTS In 16,425 patients (70.8% men) with complete follow-up data after 1.2 ± 0.8 years the adjusted relative risk ratio (aRRR) for the discontinuation of CPAP was 0.57 (95% confidence interval (CI) 0.50-0.65) for use of humidifier, 0.87 (95% CI 0.82-0.92) for increasing age per 10 years, 0.80 (95% CI 0.77-0.83) for increasing apnea hypopnea index (AHI) per 5 units/hour, and 0.96 (95% CI 0.95-0.97) per increased unit on the Epworth Sleepiness Scale (ESS). Increasing BMI was associated with increased adherence up to BMI 35. Women and patients with hypertension ran an increased risk of discontinuing CPAP treatment, aRRR 1.28 (95% CI 1.12-1.46) and 1.24 (95% CI 1.12-1.42) respectively. The adjusted hazard ratio (HR) for mortality was 1.74 (95% CI 1.32-2.28) among those who did not adhere to CPAP (median follow-up period 2.4 years after the one year adherence evaluation). CONCLUSION Use of humidifier is associated with greater adherence to CPAP treatment. Other factors predicting adherence are increasing age, more severe OSA and overweight up to BMI 35, whereas female gender and coexisting hypertension are risk factors for discontinuation of CPAP. Failure to adhere to CPAP is associated with increased mortality.
