Perception of sleep duration in adult patients with suspected obstructive sleep apnea.

ABSTRACT: PURPOSE:Discrepancies between subjective and objective measures of total sleep time (TST) are frequent among insomnia patients, but this issue remains scarcely investigated in obstructive sleep apnea (OSA). We aimed to evaluate if sleep perception is affected by the severity of OSA. METHODS:We performed a 3-month cross-sectional study of Brazilian adults undergoing overnight polysomnography (PSG). TST was objectively assessed from PSG and by a self-reported questionnaire (subjective measurement). Sleep perception index (SPI) was defined by the ratio of subjective and objective values. Diagnosis of OSA was based on an apnea/hypopnea index (AHI) ? 5.0/h, being its severity classified according to AHI thresholds: 5.0-14.9/h (mild OSA), 15.0-29.9/h (moderate OSA), and ? 30.0/h (severe OSA). RESULTS:Overall, 727 patients were included (58.0% males). A significant difference was found in SPI between non-OSA and OSA groups (p = 0.014). Mean SPI values significantly decreased as the OSA severity increased: without OSA (100.1 ± 40.9%), mild OSA (95.1 ± 24.6%), moderate OSA (93.5 ± 25.2%), and severe OSA (90.6 ± 28.2%), p = 0.036. Using logistic regression, increasing SPI was associated with a reduction in the likelihood of presenting any OSA (p = 0.018), moderate/severe OSA (p = 0.019), and severe OSA (p = 0.028). However, insomnia was not considered as an independent variable for the presence of any OSA, moderate/severe OSA, and severe OSA (all p-values > 0.05). CONCLUSION:In a clinical referral cohort, SPI significantly decreases with increasing OSA severity, but is not modified by the presence of insomnia symptoms.

Project description:Study objectivesPatients with obstructive sleep apnea (OSA) have been shown to have high levels of inflammatory markers. Anti-inflammatory treatment with montelukast and intranasal steroids have demonstrated efficacy for mild OSA in children; this has not been fully evaluated in adults. This study investigated the response of mild OSA in adults to anti-inflammatory medical therapy.MethodsAdults aged ≥ 21 years with an apnea-hypopnea index (AHI) ≤ 15 events/h on polysomnography (PSG) were recruited to a prospective double-blind, randomized control trial. Patients were treated for 12 weeks with montelukast and fluticasone or placebo. All underwent a pretreatment and posttreatment PSG. Epworth Sleepiness Scale (ESS) score was obtained pretreatment and at 6 and 12 weeks posttreatment.ResultsA total of 26 patients completed the study with 13 in each group. Mean age in the treatment and placebo groups were 58.3 ± 10.3 and 54.8 ± 14 years, respectively. There was no significant difference between groups reporting nasal congestion (P = .186), rhinitis (P = .666), or snoring (P = .177). There was no difference in the pretreatment ESS score (P = .077), body mass index (P = .173), or AHI (P = .535). The posttreatment PSG in the treatment group demonstrated a significant increase in total sleep time (P = .02) and percent of stage R sleep (P = .05). Neither group showed significant change in AHI. In patients in the treatment group, the 6- and 12-week follow-up ESS scores were not significantly different from pretreatment scores (P = .37-.46).ConclusionsIntranasal steroids and montelukast did not decrease AHI; however, total sleep time and percent of stage R sleep significantly increased. Self-reported improvement could be explained by observed changes in sleep parameters. Larger prospective studies could help elucidate the effects of medical therapy on adult patients with OSA.Clinical trial registrationRegistry: ClinicalTrials.gov; Title: Montelukast and Nasa ICS for Treatment of Mild Obstructive Sleep Apnea in Adults; Identifier: NCT01089647; URL: https://clinicaltrials.gov/ct2/show/record/NCT01089647.

Project description:BackgroundScreening and optimizing patients for OSA in the perioperative period may reduce postoperative complications. However, sleep studies can be difficult to obtain before surgery. Previous surveys reported that the majority of sleep physicians would delay surgery to diagnose and manage OSA, but most anesthesiologists would not. While disagreements exist, the importance of shared decision making and patient preferences have never been studied on this topic. It is unknown whether patients with suspected OSA, when given information about OSA, would be willing to delay surgery to diagnose and manage their condition preoperatively.MethodsThis study consisted of a self-administered questionnaire that surveyed patients, patient relatives, or any accompanying members. The survey was conducted in the preoperative clinic or in the perioperative patient and family waiting area at two hospitals in Canada and in the United States. A hypothetical scenario was used: participants were given information about OSA, and asked about their preferences regarding preoperative management should they be at risk for OSA in the setting of pending elective surgery. The objective of this study was to determine whether respondents preferred to 1) proceed with surgery as planned, 2) delay surgery to ensure the medical condition of OSA is diagnosed and optimized, or 3) let his/her physician decide.ResultsThe final survey contained 19 questions and the survey was conducted from June 2016 to September 2016. Four hundred and seventy-three surveys were collected. Forty-four percent of respondents, when given information about OSA, preferred to delay surgery pending a sleep study and treatment. Forty percent of respondents who preferred to delay surgery would tolerate delaying up to two months.ConclusionIncreasing emphasis and significant value has been placed on shared-decision making between patients and physicians. Educating patients about the risks of OSA and incorporating patient preferences into the perioperative management of OSA may be warranted.
