“…36 However, only three of the ten studies that we evaluated reported their response rate. 29,31,34 All three studies were on the general population, and the response rate ranged from 82-91%. We assumed that most patients who were referred to sleep clinics for their sleep-related complaints were more willing to respond to the questions.…”

“…In an effort to unify the subject populations, all studies were divided into two major groups: studies on patients ''with sleep disorder problems'' 25,27,30,35 and studies on ''patients without known sleep problems''. 28,29,[31][32][33][34] Due to the high prevalence of OSA in patients with sleep disorders, we could not use the first group of studies as a reference for the strength of the questionnaires designed to screen OSA in the general population. Recent evidence shows that a test performance varies in different populations because of the severity of the disease.…”

Purpose Obstructive sleep apnea (OSA) may lead to lifethreatening problems if it is left undiagnosed. Polysomnography is the ''gold standard'' for OSA diagnosis; however, it is expensive and not widely available. The objective of this systematic review is to identify and evaluate the available questionnaires for screening OSA. Source We carried out a literature search through MEDLINE, EMBASE, and CINAHL to identify eligible studies. The methodological validity of each study was assessed using the Cochrane Methods Group's guideline. Principal findings Ten studies (n = 1,484 patients) met the inclusion criteria. The Berlin questionnaire was the most common questionnaire (four studies) followed by the Wisconsin sleep questionnaire (two studies). Four studies were conducted exclusively on ''sleep-disorder patients'', and six studies were conducted on ''patients without history of sleep disorders''. For the first group, pooled sensitivity was 72.0% (95% confidence interval [CI]: 66.0-78.0%; I 2 = 23.0%) and pooled specificity was 61.0% (95% CI: 55.0-67.0%; I 2 = 43.8%). For the second group, pooled sensitivity was 77.0% (95% CI: 73.0-80.0%; I 2 = 78.1%) and pooled specificity was 53.0% (95% CI: 50-57%; I 2 = 88.8%). The risk of verification bias could not be eliminated in eight studies due to insufficient reporting. Studies on snoring, tiredness, observed apnea, and high blood pressure (STOP) and STOP including body mass index, age, neck circumference, gender (Bang) questionnaires had the highest methodological quality. ConclusionThe existing evidence regarding the accuracy of OSA questionnaires is associated with promising but inconsistent results. This inconsistency could be due to studies with heterogeneous design (population, questionnaire type, validity). STOP and STOP-Bang questionnaires for screening of OSA in the surgical population are suggested due to their higher methodological quality and easyto-use features.

“…The prevalence of obstructive sleep apnea among adults in the Western world ranges from 3% to 28%, 5 and in the United States of America (USA), the prevalence is currently estimated to be 5% to 10%. 6,7 The prevalence of OSAS in some studies based on various questionnaires has been reported as follows: based on the Berlin 11 It is noteworthy that in some regions only 10% of the population has been adequately screened for appropriate diagnosis. 4 Discrepancies in observed prevalence and underreporting may be due to non-standardized definitions and variation between diagnostic methods.…”

CONTEXT AND OBJECTIVE: Obstructive sleep apnea syndrome (OSAS) is one of the leading causes of morbidity and mortality in adults. Early detection of the disorder and discovery of risk factors through standardized questionnaires will lead to reduction of the OSAS burden. The main aim of this study was to estimate the prevalence of OSAS symptoms and examine their association with housing characteristics. DESIGN AND SETTING: Cross-sectional study at a medical school. METHODS: Demographic, housing and body measurement data on 5,545 individuals aged 16 years and over of various races were selected from the National Health and Nutrition Examination Survey. We analyzed the probability of OSAS based on habitual snoring combined with daytime sleepiness and/or witnessed apnea. Univariate and multiple linear regression were used. RESULTS: 9.8% of the men and 6.9% of the women reported symptoms suggestive of OSAS (habitual snoring, daytime sleepiness and/or apnea). The following prevalences of symptoms were found among males and females respectively: frequent snoring 35.1%, 22.3%, excessive daytime sleepiness 6.4%, 3.4% and frequent apnea 14.9%, 20.6%. Using multiple linear regression, OSAS symptoms were correlated with gender, age, body mass index (BMI), marital status and education. Regarding housing characteristics, mildew or musty smell and pets in the environment were associated with a high probability of OSAS. CONCLUSION: OSAS symptoms were more prevalent than in developing countries. The environment was an important risk factor, but environmental factors are easier to control and manage than other variables like BMI or socioeconomic status. RESUMO

A retrospective study was conducted in 198 patients suspected to have OSA at a tertiary centre in Mumbai. The pretest probability for the presence of OSAS was performed using Sleep Apnea Clinical Score (SACS).SACS score was calculated as: Snoring 3 points, Apnea 3 points, Neck Circumference in centimeters, Systemic Hypertension 4 points. Risk stratification of SACS score was done as < 43 low risk, 43-48 moderate risk, >48 high risk. A diagnosis of OSAS was done by using the criteria laid down by American Academy of Sleep Medicine (AASM). Polysomnography (PSG) showing AHI of 5 or more was considered as diagnostic of OSA. A correlation was established between SACS and OSA using Chi square test. 29/51(56.8%) did not have OSA when their SACS score was low. 53/81(65.43%) had OSA when their SACS score was moderate. With high SACS score 56/66 (84.84%) showed presence of OSA. Overall moderate to high SACS score was able to predict OSA in 109/147 (74.15%). The correlation between SACS score and presence of OSA was highly significant (p value = 0.0000137).
