CE: Nurses Are More Exhausted Than Ever: What Should We Do About It?

ABSTRACT: For nurses, the challenges posed by demanding work environments and schedules often lead to fatigue, and this can be exacerbated during crises like the COVID-19 pandemic. In this article, the authors discuss causes and challenges of nurse fatigue and consider several evidence-based strategies and solutions for individual nurses and organizations. Barriers to implementation, including a negative workplace culture and inadequate staffing, are also described, and several resources are presented.

Associations between chronotype, social jetlag, and weekday sleep in women with irritable bowel syndrome.

Sleep deficiency is well-documented in individuals with irritable bowel syndrome (IBS). Sleep deficiency includes poor sleep quality and an inadequate amount of sleep, and is a modifiable risk factor for IBS symptom exacerbations. Prior studies in other populations have identified chronotype and social jetlag (SJL) as important determinants of sleep outcomes. However, chronotype and SJL have not been examined in women with IBS. We used multiple linear regression analyses to determine whether chronotype and SJL are associated with sleep outcomes during weekdays among women with IBS predominant constipation (IBS-C), IBS with predominant diarrhea (IBS-D), and healthy control (HC) women. This sample included 62 women with IBS (IBS-C = 29, IBS-D = 33) and 58 HC women who completed a 28-day daily diary from two study cohorts. The average age of the participants was 30.1 (SD 7.2) years. Chronotype was estimated from daily diary data with the average mid-sleep time on weekends (MSWwe). SJL was calculated by subtracting the average mid-sleep time on weekdays from MSWwe. Sleep outcomes included diary assessments of sleep quality, sleep need met, and restorative sleep during weekdays. In HCs, later chronotype was predictive of lower sleep quality (ß = -0.19, p < .01), a perception of sleep need not met (ß = -0.17, p < .001), and a less restorative sleep during weekdays (ß = -0.15, p = .073), whereas SJL was not associated with sleep outcomes. Similar to HCs, earlier chronotypes in women with IBS-C reported better sleep quality and more sufficient sleep need met and restorative sleep during weekdays than later chronotypes (all p > .05). Compared to HCs, the relationships of chronotype with weekday sleep outcomes in the women with IBS-D were in the opposite directions (all p < .05). This exploratory study suggests that chronotype expression may reflect the temporal associations of sleep outcomes within IBS bowel pattern predominance subgroups, particularly sleep quality and sleep need met. Additional investigations are warranted to examine whether specific temporal attributes of symptoms and/or symptom severity associated with IBS subgroups contribute to chronotype expression.

Online prenatal trial in mindfulness sleep management (OPTIMISM): protocol for a pilot randomized controlled trial.

BACKGROUND: Sleep deficiency affects a majority of pregnant women with significant impact on daily function, mood, and pregnancy and birth outcomes. This ongoing study combines two evidence-based strategies for improving sleep and mood, mindfulness meditation and cognitive-behavioral therapy for insomnia (CBT-I), in a unique online format to address the particular needs of pregnant women. The purpose of this study is to test the feasibility and estimate the efficacy of this novel 6-week online mindfulness meditation intervention to help pregnant women in remission from depression self-manage insomnia. METHODS: This is a two-arm, parallel group randomized controlled trial. A total of 50 pregnant women between 12 and 28 weeks gestation will be recruited from the community and randomly assigned to a mindfulness or education-only control group in a 1:1 ratio. During the study, all participants will complete six weekly online modules, daily sleep diaries, and optional participation in a treatment-specific online discussion forum. Feasibility outcome measures will include study recruitment, retention, intervention adherence (number of online modules completed, number of meditation days per week), and intervention acceptability (8-item questionnaire). The primary clinical outcome measure will be sleep quality measured with the Pittsburgh Sleep Quality Index. Secondary outcome measures will include sleep measured with actigraphy and diaries (sleep efficiency, total sleep time, total wake time), Patient-Reported Outcomes Measurement Information System (PROMIS) measures (fatigue, sleep-related impairment, sleep disturbance); mood (depression, anxiety, positive affect, quality of life); and self-management and behavior change (potential self-efficacy, self-regulation, sleep problem acceptance, and trait mindfulness). Assessments will occur at baseline and post-intervention; an additional acceptability survey will be completed 4 weeks postpartum. Analyses will examine within-group differences in outcome change scores from baseline to post-intervention. Open-ended feedback will be analyzed using qualitative content analysis. DISCUSSION: This research is innovative in addressing sleep in pregnancy using a self-management research design and methods that can be accessible and cost-effective for large numbers of pregnant women. The results from this study will inform intervention refinement and efficacy testing of the intervention in a larger randomized controlled trial. TRIAL REGISTRATION: ClinicalTrials.gov, NCT04016428.

Sleep intervention for children with asthma and their parents (SKIP Study): a novel web-based shared management pilot study.

STUDY OBJECTIVES: The objective of this study was to describe the feasibility, acceptability, and preliminary efficacy of a novel Sleep Intervention for Kids and Parents (SKIP). Parent and child primary sleep outcomes were total sleep time, wake after sleep onset (WASO), sleep efficiency (SE), and bedtime range. METHODS: Children 6-11 years of age with asthma and 1 parent, both with behavioral sleep disturbance, enrolled in this single-group pilot. The 8-week shared management intervention included weekly online educational modules, goal setting, and progress reporting. Feasibility was measured by the number of dyads who were eligible, enrolled, and retained. Acceptability was measured by survey and semistructured interview. Total sleep time, WASO, SE, and bedtime range were measured by actigraphy at baseline, after the intervention, and 12-week follow-up. Mixed-effects regression models were used to determine change in sleep outcomes from baseline. RESULTS: Thirty-three of 39 eligible dyads enrolled; of 29 dyads that started the intervention, 25 (86%) completed all study visits. SKIP was acceptable for 61% of children and 92% of parents. Compared with baseline, at follow-up, children had significantly improved WASO (-37 minutes; 95% confidence interval [CI], -44.5 to -29.7; P < .001), SE (5.4%; 95% CI, 4.2-6.5; P < .001), and bedtime range (-35.2 minutes; 95% CI, -42.9 to -27.5; P < .001). Parents also had significantly improved WASO (-13.9 minutes; 95% CI, -19.5 to -8.2; P < .001), SE (2.7%; 95% CI, 1.7-.7; P < .001), and bedtime range (-35.3 minutes; 95% CI, -51.0 to -19.7; P < .001). CONCLUSIONS: SKIP was feasible, acceptable, and we observed improved child and parent sleep outcomes except total sleep time. Following refinements, further testing of SKIP in a controlled clinical trial is warranted.

Use of a Wearable Technology and Motivational Interviews to Improve Sleep in Older Adults With Osteoarthritis and Sleep Disturbance: A Pilot Study.

The feasibility and preliminary efficacy of a mobile health self-management intervention aimed at improving sleep among older adults with osteoarthritis and disturbed sleep were evaluated. This was a one-group pre-/posttest pilot study. Feasibility was measured by the number of participants eligible, enrolled, and retained. Primary efficacy outcomes were Insomnia Severity Index (ISI) score and two sleep actigraphy variables: total sleep time (TST) and sleep efficiency (SE). Overall step count, self-efficacy (SEff), and acceptance of sleep difficulties (ASD) were mechanisms of action variables. Assessments were at baseline, Week 14 (postintervention), and Week 19 (follow up). Mixed effect models were used to measure change over time. Twenty-four participants (mean age = 71 years) were enrolled and 22 completed the study. Improvements of 1.2 (95% confidence interval [CI] [-2.43, -0.05]; p = 0.04) and 2.5 (95% CI [0.9, 4.9]; p = 0.02) points in the ISI and ASD scores, respectively, were found over the 19-week period. These findings add to a growing literature that suggests older adults might reap benefits from mobile health interventions. TARGETS: Older adults with osteoarthritis and insomnia symptoms. INTERVENTION DESCRIPTION: Activity trackers synced to a dashboard that triggered personalized weekly step goals and motivational messages augmented by telephone motivational interviews. MECHANISM OF ACTION: Physical activity, SEff, and ASD. OUTCOMES: Sleep measures. [Res Gerontol Nurs. 2019; 12(4):167-173.].

Auricular Acupuncture for Chronic Pain and Insomnia: A Randomized Clinical Trial.

Objective: In the United States, ∼1.6 million adults use complementary and alternative or integrative medicine for treating pain and insomnia. However, very few studies have tested the use of auricular acupuncture using a standard protocol for chronic pain and insomnia. The aims of this research were to assess the feasibility and credibility of auricular acupuncture, and to evaluate the effects of auricular acupuncture on pain severity and interference scores, and on insomnia severity over an 8-day study period. Materials and Methods: Forty-five participants were randomized to either an auricular acupuncture group (AAG) or a usual care group (CG) on study day 4. A standard auricular acupuncture protocol was administered, with penetrating semipermanent acupuncture needles in place for up to 4 days. The main outcome measures were feasibility of conducting the study, credibility of auricular acupuncture as a treatment modality, Brief Pain Inventory pain severity and interference scores, and Insomnia Severity Index (ISI) scores. Results: There was high interest in the study and the retention was 96%. Credibility of auricular acupuncture as a treatment was high in both groups. The use of the standard auricular acupuncture protocol in the AAG led to significant within- and between-group reduced pain severity and interference scores, compared to the CG. Both groups showed within-group decreased ISI scores. However, the AAG showed significant between-group reduced ISI severity scores compared to the CG. Conclusions: With the heightened focus on the opioid crisis in the United States, this easy-to-administer protocol may be an option for treating military beneficiaries who have chronic pain and insomnia.

Smartphone Applications to Support Sleep Self-Management: Review and Evaluation.

STUDY OBJECTIVES: Mobile health (mHealth) tools such as smartphone applications (apps) have potential to support sleep self-management. The objective of this review was to identify the status of available consumer mHealth apps targeted toward supporting sleep self-management and assess their functionalities. METHODS: We searched four mobile app stores (iTunes Appstore, Android Google Play, Amazon Appstore, and Microsoft Appstore) using the terms "sleep", "sleep management," "sleep monitoring," and "sleep tracking." Apps were evaluated using the Mobile Application Rating Scale (MARS) and the IMS Institute for Healthcare Informatics functionality scores. RESULTS: We identified 2,431 potentially relevant apps, of which 73 met inclusion criteria. Most apps were excluded because they were unrelated to sleep self-management, simply provided alarm service, or solely played relaxation sounds in an attempt to improve sleep. The median overall MARS score was 3.1 out of 5, and more than half of apps (42/73, 58%) had a minimum acceptability score of 3.0. The apps had on average 7 functions based on the IMS functionality criteria (range 2 to 11). A record function was present in all apps but only eight had the function to intervene. About half of the apps (33/73, 45%) collected data automatically using embedded sensors, 27 apps allowed the user to manually enter sleep data, and 14 apps supported both types of data recording. CONCLUSIONS: The findings suggest that few apps meet prespecified criteria for quality, content, and functionality for sleep self-management. Despite the rapid evolution of sleep self-management apps, lack of validation studies is a significant concern that limits the clinical value of these apps.

Sleep Disturbances and Neurobehavioral Performance in Juvenile Idiopathic Arthritis.

OBJECTIVE: To examine the extent of polysomnographic (PSG) sleep disturbances [obstructive apnea hypopnea index (OAHI), number of wake bouts, arousals, periodic limb movements] and the effect of OAHI on neurobehavioral performance in juvenile idiopathic arthritis (JIA) with obstructive sleep apnea (OSA), JIA without OSA, and controls without OSA, adjusting for intelligence quotient (IQ), pain, medications, daytime sleepiness, and wake bouts. METHODS: Children 6-11 years, 68 with JIA and 67 controls, underwent 1 night of PSG and completed self-reported daytime sleepiness surveys, multiple sleep latency tests for physiological sleepiness, and neurobehavioral performance tests the next day. RESULTS: Compared with JIA and controls without OSA, mean OAHI and arousals were significantly higher in JIA with OSA (p < 0.001, respectively). In comparison with JIA and controls without OSA, mean simple reaction time and sustained attention were significantly slower in JIA with OSA, adjusting for IQ, pain, any medication, daytime sleepiness, and wake bouts. CONCLUSION: Elevated OAHI is suggestive of obstructive sleep apnea and a comorbidity in JIA that may predispose children with JIA to daytime sleepiness and impaired neurobehavioral performance.

Congruence between polysomnography obstructive sleep apnea and the pediatric sleep questionnaire: fatigue and health-related quality of life in juvenile idiopathic arthritis.

PURPOSE: To examine the congruence between polysomnography obstructive apnea hypopnea index (OAHI) and parent-reported obstructive sleep apnea (OSA) symptoms in 6- to 11-year-old children with juvenile idiopathic arthritis (JIA) and controls; and to compare fatigue and quality of life in JIA and control children based on OAHI and OSA symptoms. METHODS: Sixty-eight children with JIA and 75 controls and a parent participated. Children underwent one night of polysomnography in a sleep laboratory. Parents completed the sleep-related breathing disorders scale-pediatric sleep questionnaire (PSQ), and both children and parents completed the Pediatric Quality of Life Generic Core Scale and the Multidimensional Fatigue Scale. RESULTS: In JIA, 86% who met the OAHI clinical criteria for OSA (≥1.5) were above the PSQ OSA symptom cut-off score with a sensitivity of 0.86 and a specificity of 0.28. In the control group, 63% who met the OAHI clinical criteria for OSA were above the PSQ OSA symptom cut-off score, with a sensitivity of 0.63 and a specificity of 0.42. All children above both the clinical criteria for OAHI and OSA symptom cut-off score had the most impaired quality of life and greater fatigue compared to those below both the clinical criteria for OAHI and the OSA symptom cut-off score. CONCLUSION: Children who meet clinical criteria for OSA and also scored high on a parent-reported screening tool for OSA symptoms had the most impaired quality of life and more fatigue. The PSQ has potential to identify children at risk for OSA.

Effects of Yoga and Aerobic Exercise on Actigraphic Sleep Parameters in Menopausal Women with Hot Flashes.

STUDY OBJECTIVES: To determine effects of yoga and aerobic exercise compared with usual activity on objective assessments of sleep in midlife women. METHODS: Secondary analyses of a randomized controlled trial in the Menopause Strategies: Finding Lasting Answers for Symptoms and Health (MsFLASH) network conducted among 186 late transition and postmenopausal women aged 40-62 y with hot flashes. Women were randomized to 12 w of yoga, supervised aerobic exercise, or usual activity. The mean and coefficient of variation (CV) of change in actigraph sleep measures from each intervention group were compared to the usual activity group using linear regression models. RESULTS: Baseline values of the primary sleep measures for the entire sample were mean total sleep time (TST) = 407.5 ± 56.7 min; mean wake after sleep onset (WASO) = 54.6 ± 21.8 min; mean CV for WASO = 37.7 ± 18.7 and mean CV for number of long awakenings > 5 min = 81.5 ± 46.9. Changes in the actigraphic sleep outcomes from baseline to weeks 11-12 were small, and none differed between groups. In an exploratory analysis, women with baseline Pittsburgh Sleep Quality Index higher than 8 had significantly reduced TST-CV following yoga compared with usual activity. CONCLUSIONS: This study adds to the currently scant literature on objective sleep outcomes from yoga and aerobic exercise interventions for this population. Although small effects on self-reported sleep quality were previously reported, the interventions had no statistically significant effects on actigraph measures, except for potentially improved sleep stability with yoga in women with poor self-reported sleep quality.

A yoga & exercise randomized controlled trial for vasomotor symptoms: Effects on heart rate variability.

OBJECTIVES: Heart rate variability (HRV) reflects the integration of the parasympathetic nervous system with the rest of the body. Studies on the effects of yoga and exercise on HRV have been mixed but suggest that exercise increases HRV. We conducted a secondary analysis of the effect of yoga and exercise on HRV based on a randomized clinical trial of treatments for vasomotor symptoms in peri/post-menopausal women. DESIGN: Randomized clinical trial of behavioral interventions in women with vasomotor symptoms (n=335), 40-62 years old from three clinical study sites. INTERVENTIONS: 12-weeks of a yoga program, designed specifically for mid-life women, or a supervised aerobic exercise-training program with specific intensity and energy expenditure goals, compared to a usual activity group. MAIN OUTCOME MEASURES: Time and frequency domain HRV measured at baseline and at 12 weeks for 15min using Holter monitors. RESULTS: Women had a median of 7.6 vasomotor symptoms per 24h. Time and frequency domain HRV measures did not change significantly in either of the intervention groups compared to the change in the usual activity group. HRV results did not differ when the analyses were restricted to post-menopausal women. CONCLUSIONS: Although yoga and exercise have been shown to increase parasympathetic-mediated HRV in other populations, neither intervention increased HRV in middle-aged women with vasomotor symptoms. Mixed results in previous research may be due to sample differences. Yoga and exercise likely improve short-term health in middle-aged women through mechanisms other than HRV.

Telephone-Based Cognitive Behavioral Therapy for Insomnia in Perimenopausal and Postmenopausal Women With Vasomotor Symptoms: A MsFLASH Randomized Clinical Trial.

IMPORTANCE: Effective, practical, nonpharmacologic therapies are needed to treat menopause-related insomnia symptoms in primary and women's specialty care settings. OBJECTIVE: To evaluate the efficacy of telephone-based cognitive behavioral therapy for insomnia (CBT-I) vs menopause education control (MEC). DESIGN, SETTING, AND PARTICIPANTS: A single-site, randomized clinical trial was conducted from September 1, 2013, to August 31, 2015, in western Washington State among 106 perimenopausal or postmenopausal women aged 40 to 65 years with moderate insomnia symptoms (Insomnia Severity Index [ISI] score, ≥12) and 2 or more daily hot flashes. Blinded assessments were conducted at baseline, 8, and 24 weeks postrandomization. An intent-to-treat analysis was conducted. INTERVENTIONS: Six CBT-I or MEC telephone sessions in 8 weeks. Participants submitted weekly electronic sleep diaries and received group-specific written educational materials. The CBT-I sessions included sleep restriction, stimulus control, sleep hygiene education, cognitive restructuring, and behavioral homework; MEC sessions provided information about menopause and women's health. MAIN OUTCOMES AND MEASURES: Primary outcome was scores on the ISI (score range, 0-28; scores ≥15 indicate moderate to severe insomnia). Secondary outcome was scores on the Pittsburgh Sleep Quality Index (score range, 0-21; higher scores indicate worse sleep quality). Additional outcomes included sleep and hot flash diary variables and hot flash interference. RESULTS: At 8 weeks, ISI scores had decreased 9.9 points among 53 women receiving CBT-I (mean [SD] age, 55.0 [3.5] years) and 4.7 points among 53 women receiving MEC (age, 54.7 [4.7] years), a mean between-group difference of 5.2 points (95% CI, -6.1 to -3.3; P < .001). Pittsburgh Sleep Quality Index scores decreased 4.0 points in women receiving CBT-I and 1.4 points in women receiving MEC, a mean between-group difference of 2.7 points (95% CI, -3.9 to -1.5; P < .001). Significant group differences were sustained at 24 weeks. At 8 and 24 weeks, 33 of 47 women (70%) and 37 of 44 (84%) in the CBT-I group, respectively, had ISI scores in the no-insomnia range compared with 10 of 41 (24%) and 16 of 37 (43%) in the MEC group, respectively. The CBT-I group also had greater improvements in diary-reported sleep latency, wake time, and sleep efficiency. There were no between-group differences in frequency of daily hot flashes, but hot flash interference was significantly decreased at 8 weeks for the CBT-I group (-15.7; 95% CI, -20.4 to -11.0) compared with the MEC group (-7.1; 95% CI, -14.6 to 0.4) (P = .03), differences that were maintained at 24 weeks for the CBT-I group (-22.8; 95% CI, -28.6 to -16.9) and MEC group (-11.6; 95% CI, -19.4 to -3.8) (P = .003). CONCLUSIONS AND RELEVANCE: Telephone-based CBT-I improved sleep in perimenopausal and postmenopausal women with insomnia and hot flashes. Results support further development and testing of centralized CBT-I programs for treating menopausal insomnia. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT01936441.

Sleep Hygiene and Sleep Quality of Third-Trimester Pregnant Women.

The purpose of this descriptive study was to examine the associations of sleep hygiene and actigraphy measures of sleep with self-reported sleep quality in 197 pregnant women in northern Taiwan. Third-trimester pregnant women completed the Sleep Hygiene Practice Scale (SHPS) and the Pittsburgh Sleep Quality Index (PSQI) as well as the Center for Epidemiologic Studies-Depression Scale (CES-D), and wore an actigraph for 7 consecutive days. Student's t-test was used to compare the SHPS scores and means as well as variability of actigraphy sleep variables between poor sleepers (i.e., PSQI global score >5) and good sleepers (i.e., PSQI global score ≤5). Compared to good sleepers, poor sleepers reported significantly worse sleep hygiene, with higher SHPS scores and higher sleep schedule, arousal-related behavior, and sleep environment subscale scores. Poor sleepers had significantly greater intra-individual variability of sleep onset latency, total nighttime sleep, and wake after sleep onset than good sleepers. In stepwise linear regression, older maternal age (p = .01), fewer employment hours per week (p = .01), higher CES-D total score (p < .01), and higher SHPS arousal-related behavior subscale scores (p < .01) predicted self-reported global sleep quality. Findings support avoiding physically, physiologically, emotionally, or cognitively arousing activities before bedtime as a target for sleep-hygiene intervention in women during pregnancy.

Is heart rate variability associated with frequency and intensity of vasomotor symptoms among healthy perimenopausal and postmenopausal women?

OBJECTIVE: Research has suggested that the autonomic nervous system (ANS) is involved in the experience of vasomotor symptoms (VMS) during menopause. We examined the relationship of VMS intensity and heart rate variability (HRV), a measure of ANS function. METHODS: Women (n = 282) were recruited from three American states for a clinical trial of yoga, exercise, and omega-3 fatty acid supplements for VMS. To be eligible, women had to report at least 14 VMS per week, with some being moderate to severe. Sitting electrocardiograms were recorded for 15 min using Holter monitors at both baseline and 12-week follow-up. Time and frequency domain HRV measures were calculated. Women completed daily diary measures of VMS frequency and intensity for 2 weeks at baseline and for 1 week at the follow-up assessment 12 weeks later. Multivariable linear regression was used to assess the relationship between VMS and baseline HRV measures and to compare change in HRV with change in VMS over the 12 weeks. RESULTS: Baseline HRV was not associated with either VMS frequency or intensity at baseline. Change in HRV was not associated with change in VMS frequency or intensity across the follow-up. INTERPRETATION: Heart rate variability (HRV) was not associated with basal VMS frequency or intensity in perimenopausal and postmenopausal women experiencing high levels of VMS. Autonomic function may be associated with the onset or presence of VMS, but not with the number or intensity of these symptoms.

Consumer Sleep Technologies: A Review of the Landscape.

OBJECTIVE: To review sleep related consumer technologies, including mobile electronic device "apps," wearable devices, and other technologies. Validation and methodological transparency, the effect on clinical sleep medicine, and various social, legal, and ethical issues are discussed. METHODS: We reviewed publications from the digital libraries of the Association for Computing Machinery, Institute of Electrical and Electronics Engineers, and PubMed; publications from consumer technology websites; and mobile device app marketplaces. Search terms included "sleep technology," "sleep app," and "sleep monitoring." RESULTS: Consumer sleep technologies are categorized by delivery platform including mobile device apps (integrated with a mobile operating system and utilizing mobile device functions such as the camera or microphone), wearable devices (on the body or attached to clothing), embedded devices (integrated into furniture or other fixtures in the native sleep environment), accessory appliances, and conventional desktop/website resources. Their primary goals include facilitation of sleep induction or wakening, self-guided sleep assessment, entertainment, social connection, information sharing, and sleep education. CONCLUSIONS: Consumer sleep technologies are changing the landscape of sleep health and clinical sleep medicine. These technologies have the potential to both improve and impair collective and individual sleep health depending on method of implementation.

Confirmatory factor analysis of the Pittsburgh Sleep Quality Index in women with hot flashes.

OBJECTIVE: Women, especially those with hot flashes, report poor sleep quality during various stages of the menopausal transition and postmenopause. Sleep measurements vary widely because of the copious instruments available. The Pittsburgh Sleep Quality Index (PSQI) is a frequently used questionnaire that produces a single score for sleep quality. This one-factor structure has not received consistent support in the literature. The goal of this analysis was to determine the best factor structure of the PSQI in women with hot flashes. METHODS: A confirmatory factor analysis was conducted on PSQI baseline data from three randomized controlled clinical trials enrolling perimenopausal and postmenopausal women with hot flashes (N = 849) from the Menopause Strategies: Finding Lasting Answers for Symptoms and Health network. Several a priori factor models were compared. RESULTS: One-factor and two-factor models did not fit the data. A three-factor model comprising sleep efficiency, perceived sleep quality, and daily disturbance showed good fit; however, the sleep medication item was dropped because of poor fit and low rates of sleep medication use. The three-factor model was examined in African-American and white subsamples and was found to be similar in both groups; however, two items showed small group differences in strength as indicators. CONCLUSIONS: Sleep quality in midlife women with hot flashes, as measured by the PSQI, seems to comprise three correlated factors. Minor measurement differences detected between groups are of research interest but do not necessitate different scoring practices. Additional research is needed to further define sleep quality and its associations with health-related outcomes.

Nurses' knowledge of pain management for patients with combat-related traumatic brain injuries on rehabilitation units.

PURPOSE: The purpose of this project was to survey nurses' knowledge of pain management for patients with combat-related traumatic brain injuries (TBI). DESIGN/METHODS: A survey was used to collect data regarding nurses' knowledge of pain assessment and management for patients with combat-related TBI. Nurses were invited to participate in the study via email and provided with a link to the electronic survey. FINDINGS: Twenty-five surveys were returned (52% response rate). A total of 76% of nurse respondents perceived that TBI patients over report pain intensity. Only 40% of nurses were able to correctly identify the appropriate medication to treat migraine-type headache pain in TBI patients. CONCLUSION: This study identified gaps in knowledge regarding pain management for patients with combat related TBIs. CLINICAL RELEVANCE: Nurses need additional education regarding common pain syndromes, available treatments, and a better understanding of addiction in order to provide optimal care to these patients.
