Association of High-Risk Obstructive Sleep Apnea with Artificial Intelligence-Guided, CT-Based Severity Scores in Patients with COVID-19 Pneumonia

Background: We have previously demonstrated that high-risk obstructive sleep apnea (HR-OSA), based on a modified Berlin Questionnaire (mBQ), is linked to worse clinical outcomes. Chest computed tomography (CT) imaging with the implementation of an artificial intelligence (AI) analysis program has been a valuable tool for the speedy assessment of huge numbers of patients during the COVID-19 epidemic. In the current study, we addressed how the severity of AI-guided, CT-based total opacity ratio (TOR) scores are associated with high-risk OSA and short-term outcomes in the same cohort. Methods: The ratio of the volume of high opacity areas to that of the total lung volume constituted the TOR. We arbitrarily applied thresholds of <5 (no or mild TOR), ≥5 and <15 (moderate TOR), and ≥15 (severe TOR). Results: In total, 221 patients were included. HR-OSA was observed among 11.0% of the no or mild TOR group, 22.2% of the moderate TOR group, and 38.7% of the severe TOR group (p < 0.001). In a logistic regression analysis, HR-OSA was associated with a severe TOR with an adjusted odds ratio of 3.06 (95% confidence interval [CI] 1.27–7.44; p = 0.01). A moderate TOR predicted clinical worsening with an adjusted hazard ratio (HR) of 1.93 (95% CI 1.00–3.72; p = 0.05) and a severe TOR predicted worsening with an HR of 3.06 (95% CI 1.56–5.99; p = 0.001). Conclusions: Our results offer additional radiological proof of the relationship between HR-OSA and worse outcomes in patients with COVID-19 pneumonia. A TOR may also potentially indicate the individuals that are at higher risk of HR-OSA, enabling early intervention and management strategies. The clinical significance of TOR thresholds needs further evaluation in larger samples.

Validation of the European Obstructive Sleep Apnea Screening (EUROSAS) in Professional Male Drivers.

(1) Background: The European Union Driver License Committee recently developed a questionnaire as a screening tool for obstructive sleep apnea (OSA), named the European Obstructive Sleep Apnea Screening (EUROSAS) questionnaire for drivers. The aim of the current study was to investigate the diagnostic performance of the EUROSAS to predict risk of OSA in professional male drivers. (2) Methods: Fifty-eight drivers were included in the current study. All participants were asked to fill out the EUROSAS before an overnight polysomnography (PSG) in the hospital. OSA was defined as an apnea-hypopnea index (AHI) 5 events/hour on the PSG. (3) Results: Out of 58 participants, the EUROSAS correctly identified 39 (67.2%) cases as having high-risk OSA and one patient as having low-risk OSA, using AHI ≥ 5 events/h. The results indicated that the EUROSAS has a sensitivity of 67.2%, a specificity of 33.3%, a positive predictive value of 94.8%, and a negative predictive value of 5.2%. Similar results were obtained using AHI cut-offs of 15 and 30 events/h. (4) Conclusions: The EUROSAS provides a moderate level of accuracy for the screening of OSA in the professional male drivers. It seems that the diagnostic performance of the EUROSAS is not promising as an alternative questionnaire to identify professional drivers with OSA, probably due to participant response bias. Despite its limited evidence, the EUROSAS might have potential as a clinical screening tool in the general population.

Impact of mini-dose dexmedetomidine supplemented analgesia on sleep structure in patients at high risk of obstructive sleep apnea: a pilot trial.

Obstructive sleep apnea (OSA) is common in surgical patients and associated with worse perioperative outcomes. To investigate the effect of mini-dose dexmedetomidine supplemented analgesia on postoperative sleep quality pattern in patients at high risk of OSA. A pilot randomized, double-blind, placebo-controlled trial. A tertiary university hospital in Beijing, China. One hundred and fifty-two adult patients who had a STOP-Bang score ≥3 and a serum bicarbonate level ≥28 mmol/L and were scheduled for major noncardiac surgery between 29 January 2021 and 20 September 2022. After surgery, patients were provided with high-flow nasal cannula and randomized in a 1:1 ratio to receive self-controlled opioid analgesia supplemented with either mini-dose dexmedetomidine (median 0.02 μg/kg/h) or placebo. We monitored polysomnogram from 9:00 pm to 6:00 am during the first night. Our primary outcome was the percentage of stage 2 non-rapid eye movement (N2) sleep. Secondary and exploratory outcomes included other postoperative sleep structure parameters, sleep-respiratory parameters, and subjective sleep quality (Richards-Campbell Sleep Questionnaire; 0-100 score range, higher score better). All 152 patients were included in intention-to-treat analysis; 123 patients were included in sleep structure analysis. Mini-dose dexmedetomidine supplemented analgesia increased the percentage of stage N2 sleep (median difference, 10%; 95% CI, 1 to 21%; p = 0.029); it also decreased the percentage of stage N1 sleep (median difference, -10%; 95% CI, -20% to -1%; p = 0.042). Other sleep structure and sleep-respiratory parameters did not differ significantly between the two groups. Subjective sleep quality was slightly improved with dexmedetomidine on the night of surgery, but not statistically significant (median difference, 6; 95% CI, 0 to 13; p = 0.060). Adverse events were similar between groups. Among patients at high risk of OSA who underwent noncardiac surgery, mini-dose dexmedetomidine supplemented analgesia may improve sleep quality without increasing adverse events.

Correlations between clinical parameters and PSQ in children with suspected OSA

The aim of this study was to measure tonsils and adenoid vegetations, investigate the modified Mallampati score, determine BMI according to body mass and corresponding percentile, and compare these data with the results of the Pediatric Sleep Questionnaire (PSQ). The subjects were children aged 2 to 18 who were indicated for adenotonsillectomy at the Clinic for Otorhinolaryngology and Head and Neck Surgery. A doctor specialist conducted the clinical examinations. According to the PSQ, 75 subjects were divided into two groups: those at high risk and those at low risk for developing obstructive sleep apnea (OSA). The PSQ results showed that 45 subjects (60 %) were at high risk for OSA, and these subjects had significantly lower weight and BMI. Although a higher number of subjects had grade 4 tonsils and grade 3 and 4 adenoids, this distribution was not statistically significant. There was no statistically significant difference in the distribution of the modified Mallampati score when compared with the PSQ results. Lower body mass and BMI were statistically significant risk factors for OSA, while the size of the tonsils and adenoids, as well as the modified Mallampati score, did not show any statistically significant difference in comparison with the PSQ results.

Association between health-related behaviors and obstructive sleep apnea among Korean adults

We aimed to investigate the association between health-related behaviors and obstructive sleep apnea (OSA) among Korean adults. A cross-sectional design using national open data was employed. Data from 8,096 adults aged 40 years and above who participated in the Korea National Health and Nutrition Examination Survey between 2019 and 2021 were analyzed. The participants’ OSA risk level was assessed using the STOP-Bang questionnaire. A logistic regression analysis was performed to investigate the association between health-related behaviors and high risk for OSA. The association between health-related behaviors and OSA risk remained significant for former smokers (OR = 1.643) and high-risk drinking (OR = 1.365), after adjusting for variables that showed significant differences in general and metabolic characteristics. Implementing lifestyle modifications is crucial for mitigating the health and societal impact of OSA. Understanding and addressing modifiable risk factors, including high-risk drinking and smoking, should be prioritized in nursing intervention. Nursing interventions are critical for preventing and managing OSA among Korean adults. Prioritizing high-risk behaviors through cessation programs and education is essential. Vulnerability of individuals living alone must be addressed through community outreach and support services. Emphasizing routine screenings for pre-hypertension and pre-diabetes, promoting balanced nutrition, and encouraging physical activity are crucial.

Portable polygraphic device (Somnocheck micro CARDIO®) provides accurate diagnostic information in psychiatric patients at risk for obstructive sleep apnoea: an observational cohort study

BackgroundSymptoms of obstructive sleep apnoea (OSA) overlap significantly with those of psychiatric disorders, making accurate diagnosis of OSA challenging within psychiatric settings. Diagnosing OSA in psychiatric patients is crucial because untreated OSA can exacerbate psychiatric symptoms, reduce treatment efficacy, and impair overall quality of life. This study aimed to determine the diagnostic accuracy of a readily accessible procedure for psychiatric patients in a real-world clinical setting by comparing the Somnocheck micro CARDIO® (SCm) portable cardiorespiratory polygraphy device with the gold standard polysomnography (PSG).MethodsThis observational cohort study included consecutive psychiatric patients at intermediate to high risk for OSA based on screening with the STOP-Bang questionnaire, admitted to a single tertiary care centre between June 1, 2016 and December 31, 2022. The Apnoea-Hypopnoea-Index (AHI), Apnoea-Index (AI), Oxygen-Desaturation-Index (ODI), and minimum oxygen saturation were measured sequentially by SCm and PSG.ResultsA total of 57 patients were analysed (median age 62.0 [Interquartile Range (IQR), 51.5–72.5] years; 34 [59.6%] men). Regarding AHI, no significant differences (AHI measured by PSG, median, 16.6 [IQR, 6.2–26.7] vs. AHI measured by SCm, median, 14.9 [IQR, 10.0-22.8]; p = 0.812; r = 0.71) were found between SCm and PSG. AI, ODI and minimum oxygen saturation differed significantly between SCm and PSG. Using optimised cut-off values (any OSA: AHISCm ≥ 9.25), SCm showed high sensitivity (0.894) and high specificity (0.800) for the diagnosis of OSA, with an area under the receiver operating characteristic curve of 0.877.ConclusionsThis study found that the SCm portable device was accurate in identifying psychiatric patients with OSA. AHI measurement by SCm provided reliable diagnostic performance in comparison with the gold standard polysomnography. These findings support the integration of polygraphic measurements into the routine sleep assessment of psychiatric patients. Early and accurate diagnosis of OSA in this population can significantly improve the management of both sleep disorders and psychiatric conditions, potentially enhancing overall treatment outcomes and quality of life for these patients.

Obstructive sleep apnea risk and associated factors among patients with type 2 diabetes mellitus in Africa: systematic review and meta-analysis

BackgroundAlthough obstructive sleep apnea affects people all across the world, there is limited information about the conditions in developing countries, notably in Africa. This study was conducted to address the aforementioned gaps by assessing the prevalence and determinants of obstructive sleep apnea risk among patients with type 2 diabetes mellitus in Africa.MethodsTo strengthen the credibility and transparency of the study the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocol (PRISMA—P 2015) guideline were utilized for the review. Two independent reviewers searched electronic databases such as PubMed, Science Direct, and African Journal Online. The researchers used Microsoft Excel for initial data import and STATA software for statistical analysis. Cochran’s Q test was used to assess the presence of significant statistical heterogeneity I² statistic also used to quantify the degree of heterogeneity.ResultsElectronic searches produced a total of 1072 papers. The study estimates that the pooled prevalence of OSA risk among patients with type 2 diabetes mellitus in Africa is 41.13% (95% CI: 17.95–54.30, I² = 89.4%). There was significant heterogeneity among the selected studies (Q test P < 0.001) and I² (I² = 89.4%). Hypertension (AOR = 4.07, 95%CI: 2.84, 5.81), being male (AOR = 3.06, 95%CI: 0.97, 9.62), body mass index of ≥ 30 kg/m² (AOR = 3.05, 95%CI: 0.86, 10.83) and neck circumference of 40 cm (AOR = 8.55, 95%CI: 4.83, 15.12) were factors associated with obstructive sleep apnea risk among patients with type 2 diabetes mellitus.ConclusionsThe study found a high prevalence of high-risk obstructive sleep apnea risk among patients with type 2 diabetes mellitus. Male gender, body mass index of ≥ 30 kg/m² (obesity), neck circumference of > 40 cm and comorbid hypertension were significantly associated with obstructive sleep apnea risk among the study participants. The study emphasizes the importance of integrating obstructive sleep apnea screening and evaluation procedures into routine follow-up care for patients with type 2 diabetes mellitus.

Relationship between sleep bruxism and obstructive sleep apnoea: A population-based survey.

Sleep bruxism (SB) and obstructive sleep apnoea (OSA) seem to be mutually associated. This study investigates the relationship between current SB and OSA-related symptoms and the difference in OSA-related symptoms between groups based on a history of SB. An online survey was drafted to report the presence of SB and OSA in sample of 243 individuals (M = 129;F = 114;mean(SD)age = 42.4 ± 14.4 years). The Subject-Based Assessment strategy recommended in the 'Standardized Tool for the Assessment of Bruxism' (STAB) was adopted to assess SB. To evaluate OSA-related symptoms, Epworth Sleepiness Scale (ESS) and STOP-BANG questionnaires were adopted. Correlations between current SB and OSA-related symptoms were evaluated by Spearman test. ESS and STOP-BANG scores were compared by Mann-Whitney U test in individuals with and a without positive SB history. Current SB and SB history were reported by 45.7% and 39.1% of the sample, respectively. 73.7%, 21% and 5.3% of the responders showed a low, intermediate and high risk of OSA, respectively. Neither significant correlations between current SB and OSA nor significant differences between SB groups emerged. This study did neither find any significant correlation between self-report of current SB and OSA nor significant differences in ESS and STOP-BANG scores between groups based on SB history.

There is No Increased Pulmonary Risk Following Total Hip Arthroplasty in Patients Who Have Obstructive Sleep Apnea Without Underlying Lung Disease

BackgroundObstructive sleep apnea (OSA) is a frequent comorbidity. The current study evaluated whether there is a difference in the perioperative outcome after total hip arthroplasty (THA) in patients who had a low to moderate risk for OSA and high risk for OSA, respectively. MethodsAfter excluding patients who had concomitant lung disease (chronic obstructive pulmonary disease, asthma, or lung fibrosis) and those missing a STOP-Bang Score, 1,141 THA patients who had OSA were included in this retrospective study. Patients at low to moderate risk for OSA (STOP-Bang Score 0 to 4) and patients at high risk for OSA (STOP-Bang Score 5 to 8) were compared, and SpO2 (oxygen saturation) drops < 90% as well as readmission rates were compared between patients who did and did not use continuous positive airway pressure (CPAP). ResultsThere was no difference in the risk of SpO2 drop below 90% (1 versus 0%, P = 0.398) and readmission rate (2 versus 2%, P = 0.662) between patients who had low to moderate OSA risk (327 THA) and high OSA risk (814 THAs). There was no difference in SpO2 (P > 0.999) and a decrease in oxygen flow rate from the postanesthesia care unit to the morning of the first postoperative day. A CPAP device was used by 41% (467 of 1,141) of patients. There were no differences in SpO2 drop < 90% (0 versus 0%, P = 0.731) and readmission rate (2 versus 2%, P = 0.612) between patients who did and did not use a CPAP machine. ConclusionsThe current study showed no difference in perioperative outcomes between OSA patients undergoing THA who had a low STOP-Bang Score and patients who had a high STOP-Bang Score, regardless of the use of a CPAP machine. These data suggest that an elevated Stop-Bang Score does not indicate an increased perioperative risk for OSA patients when deciding on outpatient discharge.

Multiple sclerosis treatment underutilization predicts high risk for obstructive sleep apnea in patients with multiple sclerosis

BackgroundObstructive sleep apnea (OSA) is more common in patients with multiple sclerosis (MS) than in the general population, which suggests MS may predispose patients to OSA. However, the relationships between MS treatment, disease activity, disease severity, fatigue, and OSA are unknown. ObjectivesTo evaluate the connections between OSA risk, MS fatigue, and MS severity, controlling for well-established risk factors for OSA in the general population. MethodsWe administered OSA and fatigue-related questionnaires to patients with MS and collected relevant demographic and clinical data. Then, we utilized multivariate logistic regression to examine relationships between OSA risk and MS disease severity. ResultsWe identified an inverse correlation between medication possession ratio (MPR) and high OSA risk. Statistical models also demonstrated a positive correlation between fatigue and nonwhite race with high OSA risk, controlling for male sex, younger age, and body mass index (BMI). ConclusionWe identified disease-modifying therapy (DMT) underutilization, fatigue, and nonwhite race as predictors of high OSA risk in patients with MS. These findings support aggressive treatment of MS to avoid risk of comorbid OSA and MS-induced fatigue.

P115 CLINICAL PROFILE AND PREVALENCE OF OBSTRUCTIVE SLEEP APNEA IN A POPULATION OF YOUNG ADULTS REGISTERED IN A PRIMARY CARE UNIT IN RIO DE JANEIRO

Background: Obstructive Sleep Apnea (OSA) is strongly associated with high blood pressure (BP) and cardiovascular risk (CVR). There is a lack of studies and specific screening for younger populations, which could allow for early intervention and potentially reduce CVR. Objective: Analyze the prevalence and clinical profile of OSA, identifying the best screening method in a young population attended by a Family Health Strategy Unit in Rio de Janeiro. Methods: Cross-sectional population study of adults between 20 and 65 years old. Sociodemographic characteristics, anthropometric measures and CVR were obtained. Office BP was calculated using two measurements. The risk of OSA was assessed using STOP-BANG (SB) and Epworth Sleepiness Scale (ESS) questionnaires. All underwent home polysomnography. Result: 67 individuals included [38.9% men; average age of 38.9 ± 8 years]: 35 without OSA, 20 with mild OSA, 9 with moderate OSA and 3 with severe OSA. The prevalence of moderate/severe OSA was 18%. Individuals with moderate/severe OSA were older, more obese, had higher prevalence of increased neck circumference, dyslipidemia and heart rate. High risk for OSA in screening by SB, ESS and both questionnaires was respectively 55.2%, 44.8% and 19.4%. SB confirmed moderate/severe OSA in 30% in high-risk individuals, and excluded in 97% of low risk, with 60% accuracy. The sensitivity, specificity, PPV and NPV of SB to identify moderate/severe OSA were respectively 92%, 53%, 36% and 97%. In those with high risk according to the ESS, moderate/severe OSA was confirmed in 13%, while in those with low risk it was excluded in 78%. The accuracy of the ESS was 49%. The sensitivity, specificity, PPV and NPV of the ESS to identify moderate/severe OSA were respectively 33%, 53%, 13% and 78%. Conclusion: Moderate/severe OSA was more associated with an adverse metabolic profile than with high BP. The best screening questionnaire for this population is the STOP-BANG.

Screening Patients with Type 2 Diabetes at High Risk of Obstructive Sleep Apnea: A Single Tertiary Center Experience

Objective: Current guidelines suggest screening patients with type 2 diabetes (T2D) for obstructive sleep apnea (OSA). However, there is no consensus regarding the optimal method for OSA risk assessment. We aimed to identify those with diabetes who are at high risk for OSA and investigate the concordance among questionnaires utilized in assessing high OSA risk. Method: STOP, STOP-BANG, and Berlin questionnaires for the assessment of the risk of OSA and the Epworth Sleepiness Scale (ESS) for an investigation of daytime sleepiness were utilized. Results: We included 108 patients, with a median HbA1c of 7.5%, a BMI of 30.7 kg/m², and waist and neck circumferences measuring 104.3 cm and 38.9 cm, respectively. On ESS, 10.2% of patients had excessive daytime sleepiness. According to Berlin (38.9%), the number of patients at high risk of OSA was found to be lower than that of in STOP (53.7%) and STOP-BANG (68.5%) questionnaires. For patients with a BMI

Postoperative Respiratory Complications After Adenotonsillectomy in Children With High-Risk Obstructive Sleep Apnea.

Identify patient characteristics and polysomnogram (PSG) parameters associated with postoperative respiratory complications after adenotonsillectomy (AT) among children with high-risk obstructive sleep apnea (OSA). Case series with chart review. Tertiary care children's hospital. Pediatric patients (<18 years) with high-risk OSA (any 1 of: apnea-hypopnea index [AHI] >30, O2 nadir <80% and peak CO2 >60 mm Hg) on overnight PSG from 2019 to 2021 were included. Primary outcomes were major respiratory intervention during the postoperative admission, prolonged hospitalization, and intensive care unit (ICU) stay. A total of 307 patients met inclusion criteria. Median age was 6.5 years and 63% were male. Twenty-five (8.1%) required major respiratory intervention and 29 (9.7%) required ICU admission after AT. Major interventions and ICU admissions were significantly associated with neuromuscular disease (P < .01), higher obstructive apnea-hypopnea index (oAHI), higher CO2 peak, and lower O2 nadir. Prolonged admission had similar findings except oAHI was not significantly associated. Younger children were significant more likely to require ICU admission or prolonged admission. Increased oAHI and worsening O2 and CO2 parameters on preoperative PSG were associated with postoperative respiratory complications in children with high-risk OSA. Children with neuromuscular disease and age 0 to 2 had higher risk of ICU stay and prolonged hospitalization. Clinicians should recognize the importance of parameters beyond oAHI when anticipating postoperative monitoring.

Investigating the State of Sleep Disorders and the Factors Affecting Them in Patients with Multiple Sclerosis: Cross-Sectional Study

Background: Multiple sclerosis (MS) is a chronic disease that leads to non-traumatic disability and is influenced by both hereditary and environmental factors. Objectives: This study aims to investigate the state of obstructive sleep apnea (OSA) syndrome and the factors affecting it in patients with multiple sclerosis. Methods: This cross-sectional and descriptive study included 180 patients, selected based on previous studies on MS patients and the prevalence of sleep apnea syndrome. The STOP-BANG questionnaire, Epworth Sleepiness Scale (ESS), and Fatigue Severity Scale (FSS) were used for data collection. Additionally, a demographic profile form was utilized to gather information on age, sex, marital status, education level, and income status of the patients. Data were analyzed using SPSS 16 software, employing mean and standard deviation, chi-square test, ANOVA, correlation coefficient, and one-way analysis of variance. Results: The results showed that among patients with a low risk of OSA, 87.3% were female, whereas among those with a high risk of OSA, 71.4% were male. This indicates that the risk of OSA is higher in men than in women with MS. Additionally, the mean ± SD of the Epworth score in high-risk individuals was 16.41 (1.56), compared to 14.27 (1.78) in low-risk individuals, indicating poorer Epworth scores in those at high risk of OSA. Conclusions: The prevalence of OSA and other sleep disorders among patients with MS in Ilam was found to be high. Therefore, it is recommended that necessary therapeutic and rehabilitation interventions be implemented to reduce OSA and improve the sleep quality of these patients.

Comparative characteristics of patients with a combination of obstructive sleep apnea and paroxysmal atrial fibrillation in the groups of interventional and conservative treatment of arrhythmia

Aim. To compare the clinical characteristics of two groups of patients with a combination of obstructive sleep apnea (OSA) and paroxysmal atrial fibrillation (AF), undergoing conservative treatment for arrhythmia and after pulmonary vein isolation.Material and methods. The study included 362 patients with paroxysmal AF who underwent respiratory sleep monitoring.Results. A predominance of clinically significant OSA was revealed (moderate and severe — 37% and 29%, respectively), as well as a higher drug burden and comorbidity in the group of patients receiving drug treatment for AF. The threshold value of body mass index (BMI), at which a high risk of severe OSA was predicted, corresponded to class 1 obesity (BMI ≥31 kg/m2). The results obtained demonstrated an association between an increase in the left atrium anteroposterior size and the severity of OSA (4,1 [3,8-4,4] cm, r=0,28; p&lt;0,001), which may be due to cardiac structural remodeling in patients with a combination of paroxysmal AF and severe OSA.Conclusion. In a cohort of patients with paroxysmal AF, a high incidence of clinically significant OSA was revealed. In the group of patients with a combination of OSA and AF undergoing conservative treatment, more unfavorable cardiovascular characteristics and a more severe comorbid status were revealed compared to the group of patients undergoing surgical treatment.

Identifying Risk of Postoperative Cardiorespiratory Complications in OSA

Patients with obstructive sleep apnea (OSA) are at increased risk of postoperative cardiorespiratory complications and death. Attempts to stratify this risk have been inadequate, and predictors from large well-characterized cohort studies are needed. What is the relationship between OSA severity, defined by various polysomnography-derived metrics, and risk of postoperative cardiorespiratory complications or death, and which metrics best identify such risk? Cohort study of 6770 consecutive patients who underwent diagnostic polysomnography for possible OSA and a procedure involving general anesthesia within a period spanning 2 years before and at least 5 years after polysomnography. Participants were identified by linking polysomnography and health databases. Relationships between OSA severity measures and the composite primary outcome of cardiorespiratory complications or death within 30 days of hospital discharge were investigated using univariable and multivariable analyses. The primary outcome was observed in 5.3% (n=361) of the cohort. While univariable analysis showed strong dose-response relationships between this outcome and multiple OSA severity measures, multivariable analysis showed its independent predictors were: age >65 years (OR 2.67 [95%CI 2.03-3.52], p<0.0001); age 55.1-65 years (OR 1.47 [1.09-1.98], p=0.0111); time between polysomnography and procedure ≥5 years (OR 1.32 [1.02-1.70], p=0.0331), body mass index ≥35kg/m2 (OR 1.43 [1.13-1.82], p=0.0032); presence of known cardiorespiratory risk factor (OR 1.63 [1.29-2.06], p<0.0001); >4.7% of sleep time at SpO2 less than 90% (T90) (OR 1.91 [1.51-2.42], p<0.0001); and cardiothoracic procedures (OR 7.95 [5.71-11.08], p<0.001). For non-cardiothoracic procedures, age, BMI, presence of known cardiorespiratory risk factor and T90 remained the significant predictors, and a risk score based on their odds ratios was predictive of outcome (area under receiver operating characteristic curve 0.7 [95%CI 0.64-0.75]). These findings provide a basis for better identifying high-risk OSA patients and determining appropriate postoperative care.

Quality measure for screening for adult obstructive sleep apnea by primary care providers: 2024 update after measure maintenance.

Obstructive sleep apnea (OSA) is a prevalent respiratory sleep disorder that, when left undiagnosed or untreated, can lead to adverse outcomes. There continue to be gaps and variations in screening adults who are high risk for OSA in the primary care setting, leading to many adults in the United States going undiagnosed. As a part of the ongoing AASM quality measure maintenance initiative, the AASM Quality Measures Task Force reviewed the original screening for adult obstructive sleep apnea by primary care physicians quality measure. The measure was updated to further address the adult populations who are at high risk for OSA to ensure that the measure is consistent with the most current medical literature, increasing the likelihood that patients at high risk for OSA are properly screened for the sleep disorder.

Obstructive sleep apnea risk among adults with type 2 diabetes mellitus in an urban primary care setting of Mangalore, India.

Obstructive sleep apnea (OSA) is an under-evaluated and under-treated problem, particularly among individuals with type 2 diabetes mellitus (T2DM). Therefore, in this study, we aim to determine the risk of OSA among adults with T2DM residing in an urban area of Mangalore and to elucidate the determinants of OSA among the study participants. A cross-sectional study was conducted for a period of 2 months among adult patients (≥ 18 years) with T2DM seeking health care at a primary care setting located in an urban area of Mangalore. Face-to-face interviews were conducted using a semi-structured proforma. STOP-BANG questionnaire was used to assess the risk of OSA among the study participants. The measurements, such as height, weight, and neck circumference, were conducted using standard techniques. The mean age of the study participants was 58.12 ± 11.60 years. The majority, (58.30%), were males, and 45.0% reported a family history of T2DM. A total of 108 (60.0%) experienced loud snoring while asleep, while 149 (82.80%) experienced tiredness during daytime. The mean body mass index (BMI) was 24.64 ± 4.9 kg/m2, while a neck circumference of >40 cms was found in 28.90%. A total of 69 (38.30%) had a high risk of OSA with a STOP-BANG score ranging from 5 to 8, while 71 (39.40%) had a score ranging from 3 to 4 (intermediate risk). The statistically significant associations were found between age >50 years, male gender, and diabetes for ≥ 7 years and high risk of OSA (P < 0.001). More than a third of the study participants had a high risk of OSA. Age > 50 years, male gender, and diabetes for ≥7 years were the factors associated with OSA.

Impact of High Risk of Obstructive Sleep Apnea on Health-Related Quality of Life: The Korean National Health and Nutrition Survey 2019-2021.

Background/Objectives: Obstructive sleep apnea (OSA) impairs quality of life (QoL). However, its disease burden in the general population remains unknown. We aimed to investigate the association between OSA and health-related QoL in the general Korean population. Methods: This study analyzed cross-sectional datasets of adults (≥40 years) in the Korean National Health and Nutrition Examination Survey 2019-2021. QoL was assessed using the 3-level EuroQoL 5-dimension component (EQ-5D-3L). The high risk of OSA was determined using the STOP-Bang questionnaire (score ≥ 3). Demographic and clinical factors were included in linear regression analyses to identify the factors associated with EQ-5D-3L. Results: Of the 8966 total participants, 6792 (75.8%) and 2174 (24.2%) were classified as having a low risk and high risk of OSA, respectively. The high risk OSA group showed significantly lower QoL scores when compared with the low risk OSA group (0.939 ± 0.003 vs. 0.951 ± 0.002, p < 0.001). However, the mean difference was within the minimal clinically important difference (MCID) of EQ-5D-3L. Only females exceeded the MCID for the EQ-5D-3L. Elderly females with a high risk of OSA showed the lowest QoL. The regression coefficient of high risk OSA in the multivariate model was -0.018 (95% CI: -0.025--0.01, p < 0.001). Patient demographics and comorbidities also showed significant associations with the EQ-5D-3L. Their regression coefficient was higher than that of high risk OSA. Conclusions: The impact of high risk OSA on QoL manifested differently according to age and sex. The impact of comorbidities on QoL was greater than that of high risk OSA, highlighting the important role of comorbidities and the need for their adjustment in the assessment of QoL.
