Abstract
Continuous positive airway pressure (CPAP) has been the standard treatment of obstructive sleep apnoea/hypopnoea syndrome (OSA) for almost four decades. Though usually effective, this treatment suffers from poor long-term compliance. Therefore, the aim of our one centre retrospective study was to assess factors responsible for treatment failure and long-term compliance. Four hundred subsequent patients diagnosed with OSA and qualified for CPAP treatment were chosen from our database and compliance data were obtained from medical charts. Many differing factors kept patients from starting CPAP or led to termination of treatment. Overall, almost half of patients ended treatment during the mean time of observation of 3.5 years. Survival analysis revealed that 25% of patients failed at a median time of 38.2 months. From several demographic and clinical covariates in Cox’s hazard model, only the presence of a mild OSA, i.e., AHI (apnoea/hypopnoea index) below 15/h was a factor strongly associated with long term CPAP failure. The compliance results of our study are in line with numerous studies addressing this issue. Contrary to them, some demographic or clinical variables that we used in our survival model were not related to CPAP adherence.

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
OBJECTIVE To assess the predictive factors at 12 month and 10 year adherence to Continuous Positive Airway Pressure (CPAP) in patients with Obstructive Sleep Apnoea (OSA). METHODS Retrospective data analysis of patients starting CPAP between 2006 and 2009. After 12 months (T1) from start and during a 10 year follow up the following data were recorded: Body Mass Index (BMI), Time of night use, Epworth Sleepiness Scale (ESS) score. RESULTS Out of 315 patients, 147 fulfilled inclusion criteria and were evaluated. According to CPAP nighttime use during the first year, patients were divided into two groups: those using the device less < 4.5 h (Poor Adherence (PA): 61 patients), and those using ≥4.5 h: (Good Adherence (GA): 86 patients). Patients of PA group were significantly younger, had greater BMI and required more unscheduled visits during the first year. After 12 months, there were 11 (7.5%) dropouts, all in PA group. Patients using the nasal mask showed a greater prevalence among GA as compared to those using the oro-nasal mask (76.5% vs 57.8% respectively, p = 0.04). After 10 years 83 out of 147 (56.4%) patients were still under CPAP, 51 (59.3% of GA) and 32 (52.4% of PA group) respectively. Dropouts were significantly more frequent during the first 5 years (p = 0.04). CONCLUSION Ten years after prescription the majority of patients with OSA undergoing periodical controls, still perform CPAP independent of their adherence to therapy after one year of use. Use of nasal mask may be associate to better adherence.

Comorbidities associated with obstructive sleep apnea: a retrospective Egyptian study on 244 patients. Sleep Breath 2019; 23:1079-1085. [PMID: 30685854 DOI: 10.1007/s11325-019-01783-w] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2018] [Revised: 01/09/2019] [Accepted: 01/12/2019] [Indexed: 01/09/2023]
Abstract
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.

Abstract
STUDY OBJECTIVES The demand for continuous positive airway pressure (CPAP) therapy outpaces available resources in most health care settings. We sought to evaluate predictors of nonroutine CPAP follow-up visits to improve resource utilization. METHODS We randomly analyzed 1,141 of the 2,446 patients who had received at least 1 year of CPAP therapy. Reasons for contacts, type (routine = R, nonroutine = NR), and mode (face-to-face or not, physician, nurse) were collected. RESULTS A total of 771 patients were classified R, and 370 NR. Age, profession, and sex did not affect the NR frequency. Symptoms increased the odds ratio for NR 12.1-fold, somnolence 34.8-fold, and suffocation at night 10.4-fold. Patients with nonroutine reasons abandoned CPAP therapy significantly (7.6-fold) more frequently than patients with routine reasons. CONCLUSIONS Symptoms during CPAP therapy predicted the nonroutine contacts well. In line with this, patients with symptoms have become a priority follow-up group, and could constitute the only follow-up policy when dealing with insufficient medical resources.

Abstract
BACKGROUND Suboptimal CPAP adherence in OSA clinical trials involving predominantly white men limits interpretability and generalizability. We examined predictors of CPAP adherence in a clinical trial enriched with minorities. METHODS The Sleep Apnea Stress Study-a randomized, double-blind, sham-controlled trial of patients with moderate-to-severe OSA-included participants with complete 8-week adherence data (n = 138). Overnight 14-channel polysomnography, anthropometry, socioeconomic status, mood questionnaires, and week 1 CPAP adherence were analyzed via adjusted linear models relative to CPAP adherence (average minutes per night usage). RESULTS Overall, age was 51 ± 12 years, 55% of the patients were male, 55% were white, BMI was 36.7 ± 7.7 kg/m2, and median apnea-hypopnea index was 20 (interquartile range, 13-37). In univariate analyses adherence increased with randomization to active CPAP (81 min; 95% CI, 30-132), increasing age (35 min/decade; 95% CI, 13-57), white race (78 min, 95% CI, 26-129), and per hour of week 1 adherence (41 min, 95% CI, 32-51). Active CPAP (48 min, 95% CI, 6-91), increasing age (27 min/decade, 95% CI, 10-44), and higher 1-week adherence (36 min/h, 95% CI, 27-46) were significantly associated with improved adherence in multivariable analyses. Subgroup analyses showed stronger associations of adherence with treatment arm in whites and increasing age in minorities. Increasing age and white race were more strongly associated with adherence in women. CONCLUSIONS In this trial with near-even sex distribution and high ethnic minority representation, we identified CPAP assignment, increasing age, and early adherence to be associated with improved adherence in addition to sex-specific and race-specific adherence differences. These results can inform targeted clinical trial adherence optimization strategies. TRIAL REGISTRY ClinicalTrials.gov; No.: NCT00607893; URL: www.clinicaltrials.gov.
