Five-Year Subjective Outcomes of Obstructive Sleep Apnea Surgery: A Multiinstitutional Study

Objectives

To evaluate the effect of obstructive sleep apnea (OSA) surgery on long-term (5-year) subjective outcomes, including sleep disordered breathing (SDB) symptoms and other complications, in patients with OSA.

Methods

We enrolled patients who underwent diagnostic polysomnography for OSA between January 2006 and December 2006 in ten hospitals. Patients either were treated for OSA or were not treated for OSA. All patients completed a brief telephone survey regarding their SDB signs and symptoms (e.g., snoring, apnea, nocturnal arousals, and daytime sleepiness), positive airway pressure (PAP) compliance, and any adverse effects of either the surgery or PAP. A positive subjective outcome for either surgery or no treatment was taken to be the alleviation of apnea, defined as a ≥50% increase in score. A positive subjective outcome (compliance) for PAP was defined as a PAP usage of ≥4 hours per night and ≥5 days per week.

Results

A total of 229 patients were included in this study. Patients were divided into three groups: a surgery group (n=87), a PAP group (n=68), and a control (untreated) group (n=74). The surgery group exhibited significant improvement in all SDB symptoms compared with the control group. The long-term subjective outcomes of the surgery (52.9%) and PAP (54.4%) groups were significantly better than those of the control group (25.0%). The subjective outcome of the surgery group was not significantly different from that of the PAP group. The overall surgical complication rate was 23.0% (20 of 87) in the surgery group, and 55.0% (22 of 40) of all patients with PAP experienced adverse effects.

Conclusion

The extent of SDB symptoms was consistently improved in patients with OSA at 5 years postsurgery. Information about the potential long-term subjective outcomes should be provided to patients when considering surgery.     

孕妇疲乏现状及其影响因素分析

【摘要】目的 了解孕妇疲乏发生率和疲乏程度;探讨孕妇疲乏的影响因素。方法 通过整群抽样法选取上海市某三甲妇产科专科医院338例孕妇,通过自行汉化的疲乏量表(PAFS)调查孕期疲乏现况,通过自行设计的一般资料调查表获取孕妇人口学资料。结果 孕妇孕28周期间疲乏发生率高,但仅为“偶尔发生”。在控制职业、本次是否计划妊娠、睡眠时间和妊娠合并症或并发症类型之后,睡眠质量仍然是影响孕期疲乏的变量(F=15.31 P=0.000)。结论 孕妇孕28周期间疲乏普遍存在,但程度较轻。孕妇睡眠质量不佳是孕妇疲乏的重要因素。医护人员及家属应关注并采取有效措施帮助孕妇提高睡眠质量,缓解孕期疲乏。     

A work-life perspective on sleep and fatigue—looking beyond shift workers

This study examines sleep and fatigue through a work-life lens. Whilst most often thought of as an issue for shift workers, this study observed that self-reported insufficient sleep and fatigue were prevalent for workers on standard daytime schedules. Using a representative sample of 573 daytime workers (51.3% men; 70.7% aged 25−54 yr) from one Australian state, it was observed that 26.4% of daytime workers never or rarely get the seven hours of sleep a night that is recommended for good health. Those with parenting responsibilites (29.4%) or working long (45+) hours (37.4%) were most likely to report insufficient sleep. Whereas mothers in full-time work were most likely to report frequent fatigue (42.5%). This study highlights the common experience of insufficient sleep and fatigue in a daytime workforce, with significant implications for health and safety at work and outside of work. Stronger and more effective legislation addressing safe and ‘decent’ working time is clearly needed, along with greater awareness and acceptance within workplace cultures of the need to support reasonable workloads and working hours.

Sleep disruption and quality of life in persons with dementia: A state-of-the-art review

Sleep disruption in persons with dementia is pervasive and contributes to negative health outcomes and decreased quality of life. Using Lawton's framework for quality of life in persons with dementia, the aim of this state-of-the-art review was to synthesize current knowledge on the association between sleep disruption and quality of life in persons with dementia in four domains: physical, social/behavioral, emotional well-being, and cognitive. Based on the final sample of six studies, sleep disruption was negatively associated with all four quality of life domains in persons with dementia. Given the variations in research design, measurement and sample size, conclusions could not be generated on the magnitude of the effects by domain. We do, however, provide recommendations for future research and clinical practice.     

To What Extent do Sleep Quality and Duration Mediate the Effect of Perceived Discrimination on Health? Evidence from Philadelphia

Little research investigates whether sleep mediates the adverse effect of perceived discrimination on health and even less is known about whether sleep quality and sleep duration mediate the relationships in the same fashion. We applied a recently developed mediation analysis approach to a survey administered in 2008 in Philadelphia, PA, that includes 9042 adults. Health was measured with self-rated health, stress, and mental illness. Perceived discrimination was operationalized with self-reported discriminatory experience in two social contexts, namely health care system and housing market. Sleep quality and duration were measured with a five-point Likert scale and the self-reported sleep time at night, respectively. After controlling for one’s demographic, socioeconomic, and health-related characteristics, the mediation analysis quantified how much sleep quality and duration can account for the effect of perceived discrimination on these health outcomes. The key findings are: (a) sleep quality and duration accounted for approximately 15 to 25 % of the adverse effect of perceived discrimination. (b) Sleep quality is more important than sleep duration in mediating the relationship between perceived discrimination and health. (c) The proportion of the effect mediated by sleep differs by the social context where perceived discrimination occurred. It was confirmed that sleep mediates the relationship between perceived discrimination and health and the interventions to improve sleep, particularly sleep quality, should help to attenuate the effect of perceived discrimination on health.
