Association of Pain Disorder and Psychiatric Disease With Surgical Management of Obstructive Sleep Apnea.

OBJECTIVE: Patients undergoing surgical management for obstructive sleep apnea (OSA) are likely medically distinct from their counterparts not treated surgically. This study examined the associations between psychiatric and pain comorbidities and the likelihood of undergoing sleep surgery. STUDY DESIGN: A retrospective cohort study of adults with OSA. SETTING: Large integrated healthcare system. METHODS: The primary outcome was nonnasal, nonbariatric sleep surgery. The associations of baseline demographic and comorbid conditions with surgery to treat underlying OSA were examined using bivariable and multivariable analyses. RESULTS: Among 172,854 adults with OSA, 2456 received sleep surgery. Comorbid pain disorder and/or pain medication treatment was associated with 41% higher odds of surgery (95% confidence interval: 1.29-1.54). In bivariable analyses, those with a history of headache (p = .004), particularly migraine (p = .003), disorders of adult personality or behavior (p = .025), or behavioral/emotional disorder (p < .001) were more likely to undergo surgery. Younger adults were also more likely to undergo surgery (mean age at diagnosis 39.8 ± 12.6 vs 54.7 ± 14 years), as were men, Asian/Pacific Islander or Hispanic adults, those with lower body mass index (32 ± 7 vs 34.3 ± 8.1 kg/m2 ), or those with Charlson Comorbidity Index of zero (p < .001). CONCLUSION: Our study suggests a history of pain disorder (including receipt of pain medication), migraine, or certain behavioral and personality disorders are associated with an increased likelihood of undergoing sleep surgery. The findings may better characterize comorbid predictors of sleep surgery and potentially help clinicians tailor expectations, postoperative pain management, and overall sleep outcomes.

Characteristics of Adults Undergoing Soft Tissue and Orthognathic Surgery for Obstructive Sleep Apnea.

OBJECTIVE: To identify clinical and demographic characteristics of adults with obstructive sleep apnea (OSA) undergoing soft tissue and orthognathic sleep surgery, assess temporal trends in surgery type and proportion of women undergoing surgery, and provide clinical perspective before wide-spread implementation of hypoglossal nerve stimulation (HGNS). METHODS: In a retrospective cohort study, adults diagnosed with OSA from 2009 to 2016 were identified in a large integrated healthcare system. Characteristics between cohort members who did and did not undergo sleep surgeries were compared. Multivariable logistic regression models examined associations of different characteristics with whether surgery was performed. RESULTS: Of 172,216 adults with OSA, 2,262 (1.3%) underwent sleep surgery during 2009-2017. The most common sleep surgery was palate surgery (56.9%), which decreased proportionately over time. In multivariable analysis, older age and obesity were associated with lower odds of undergoing surgery. Those who underwent tonsillectomy and adenoidectomy were more likely to have larger tonsils and not require additional surgery, whereas tongue reduction recipients were more likely to have severe OSA and require multiple surgery types. The proportion of women undergoing surgery increased over time (p < 0.001 from trend test). CONCLUSION: Clinical and demographic characteristics associated with soft tissue and orthognathic sleep surgery were identified in a large adult cohort prior to widespread implementation of HGNS. An increase in sleep surgery among women and a decrease in palate surgery over time were observed. The findings provide clinical perspective on sleep surgery performed prior to implementation of HGNS and may inform future studies examining its associations with patient characteristics.

Ten-year Thyroid Cancer Incidence in an Integrated Healthcare Delivery System.

INTRODUCTION: The incidence of papillary thyroid cancer (PTC) has increased in recent decades, but data from community-based settings are limited. This study characterizes PTC trends in a large, integrated healthcare system over 10 years. METHODS: The annual incidence of PTC (2006-2015) was examined among Kaiser Permanente Northern California adults aged 21 to 84 years using Cancer Registry data, including tumor size and stage. Incidence estimates were age-adjusted using the 2010 US Census. RESULTS: Of 2990 individuals newly diagnosed with PTC (76.8% female, 52.7% non-Hispanic White), 38.5% and 61.5% were aged < 45 and < 55 years, respectively. At diagnosis, 60.9% had PTC tumors ≤ 2 cm, 9.2% had tumors > 4 cm, and 66.1% had Stage I disease. The annual age-adjusted incidence of PTC increased from 9.4 (95% confidence interval [CI] = 8.1-10.7) to 14.5 (95% CI = 13.1-16.0) per 100,000 person-years and was higher for female patients than for male patients. Incidence tended to be higher in Asian/Pacific Islanders and lower in Black individuals. Increasing incidence was notable for Stage I disease (especially 2006-2012) and evident across a range of tumor sizes (3.0-4.6 for ≤ 1 cm, 2.5-3.5 for 1-2 cm, and 2.4-4.7 for 2-4 cm) but was modest for large tumors (0.9-1.5 for > 4 cm) per 100,000 person-years. DISCUSSION: Increasing PTC incidence over 10 years was most evident for tumors ≤ 4 cm and Stage I disease. Although these findings may be attributable to greater PTC detection, the increase across a range of tumor sizes suggests that PTC burden might also have increased.

The efficacy of surgery for upper airway resistance syndrome: A systematic review, meta-analysis and case series.

PURPOSE: Upper airway resistance syndrome (UARS) is a sleep related breathing disorder that was first described in 1993. This goal of this study is to determine the efficacy of surgical intervention for UARS. MATERIALS AND METHODS: Systematic review of the literature and a case series of UARS patients at a large integrated healthcare system. Meta-analysis was performed. RESULTS: For the systematic review, 971 abstracts were reviewed and 3 articles were included, yielding 49 subjects. All of the included studies were of level 3 or 4 evidence. Significant improvement in Epworth Sleepiness Scale (ESS) score was noted after surgery in two level 4 studies. No significant change in ESS was noted in one level 3 study. Our retrospective chart review of eleven UARS patients compared preoperative and postoperative ESS scores, as well as sleep study data. Patients underwent a variety of surgical procedures. Our findings show a significant improvement in mean ESS scores after surgery, from 11.0 (±3.5) to 7.0 (±4.8) with p = 0.01, though no difference in apnea hypopnea index (AHI) and respiratory disturbance index (RDI) were identified. Meta-analysis was performed on 2 studies from the systematic review and our cases series data. UARS surgery showed a mean change in ESS of -5.89 (95% CI, -8.29 to -3.50). CONCLUSIONS: This systematic review, meta-analysis and retrospective case series indicate that surgery may improve ESS scores in patients with UARS. AHI and RDI are unlikely to be impacted by surgery.
