The Effect of a Quality Improvement Intervention on Sleep and Delirium in Critically Ill Patients in a Surgical ICU.

BACKGROUND: Delirium is a deleterious condition affecting up to 60% of patients in the surgical ICU (SICU). Few SICU-focused delirium interventions have been implemented, including those addressing sleep-wake disruption, a modifiable delirium risk factor common in critically ill patients. RESEARCH QUESTION: What is the effect on delirium and sleep quality of a multicomponent nonpharmacologic intervention aimed at improving sleep-wake disruption in patients in the SICU setting? STUDY DESIGN AND METHODS: Using a staggered pre-post design, we implemented a quality improvement intervention in two SICUs (general surgery or trauma and cardiovascular) in an academic medical center. After a preintervention (baseline) period, a multicomponent unit-wide nighttime (ie, efforts to minimize unnecessary sound and light, provision of earplugs and eye masks) and daytime (ie, raising blinds, promotion of physical activity) intervention bundle was implemented. A daily checklist was used to prompt staff to complete intervention bundle elements. Delirium was evaluated twice daily using the Confusion Assessment Method for the Intensive Care Unit. Patient sleep quality ratings were evaluated daily using the Richards-Campbell Sleep Questionnaire (RCSQ). RESULTS: Six hundred forty-six SICU admissions (332 baseline, 314 intervention) were analyzed. Median age was 61 years (interquartile range, 49-70 years); 35% of the cohort were women and 83% were White. During the intervention period, patients experienced fewer days of delirium (proportion ± SD of ICU days, 15 ± 27%) as compared with the preintervention period (20 ± 31%; P = .022), with an adjusted pre-post decrease of 4.9% (95% CI, 0.5%-9.2%; P = .03). Overall RCSQ-perceived sleep quality ratings did not change, but the RCSQ noise subscore increased (9.5% [95% CI, 1.1%-17.5%; P = .02). INTERPRETATION: Our multicomponent intervention was associated with a significant reduction in the proportion of days patients experienced delirium, reinforcing the feasibility and effectiveness of a nonpharmacologic sleep-wake bundle to reduce delirium in critically ill patients in the SICU.

Changing Adolescent Sleep Patterns: Factors Affecting them and the Related Problems.

Sleep affects physical growth, behavior and emotional development besides determining cognitive functioning, learning and attention especially of a growing child. Adolescence represents one of the critical transitions in the life span and is characterized by a tremendous pace in growth and change that is second only to that of infancy. Adolescent sleep patterns deserve particular attention because of the potential impact on school performance. Average sleep period in adolescents is reduced during school days to around seven hours. The reasons may be biological mainly the sleep phase delay or psychosocial and environmental. These include academic demands, social activities, sports, internet, television viewing, part-time employment, and use of mobile phone at night, peer and parental influence and socioeconomic status. These changing patterns of sleep in adolescents lead to many behavioral sleep problems like Delayed Sleep-phase Syndrome; Difficulties in falling asleep (insomnia); excessive daytime sleepiness, poor academic performance. Decreased sleep in adolescents also causes obesity and other cardio-metabolic abnormalities. This needs an integrated approach involving adolescents themselves, their parents, teachers and specialized physicians to help improve the sleep quantity and quality and lead to a better quality of life and daytime functioning in adolescents.

Sleep disturbance, chronic stress, and depression in hospice nurses: testing the feasibility of an intervention.

PURPOSE/OBJECTIVES: To test the feasibility of a cognitive-behavioral therapy for an insomnia (CBT-I) intervention in chronically bereaved hospice nurses. DESIGN: Five-week descriptive correlational. SETTING: Nonprofit hospice in central Texas. SAMPLE: 9 agency nurses providing direct patient and family care. METHODS: Direct care nurses were invited to participate. Two intervention group sessions occurred at the hospice agency and included identification of dysfunctional thoughts and beliefs about sleep, stimulus control, sleep hygiene, and relaxation techniques to promote sleep. Measurements were taken at baseline and three and five weeks postintervention. MAIN RESEARCH VARIABLES: Sleep quality, depressive symptoms, and narrative reflections on the impact of sleep quality on self-care. FINDINGS: Participants reported moderate-to-severe sleep disturbances and moderate depressive symptoms. The CBT-I intervention was well accepted by the participants, and on-site delivery increased participation. CONCLUSIONS: Additional longitudinal study is needed to investigate the effectiveness of CBT-I interventions to improve self-care among hospice nurses who are at high risk for compassion fatigue and, subsequently, leaving hospice care. IMPLICATIONS FOR NURSING: Hospice nurses are exposed to chronic bereavement that can result in sleep disturbances, which can negatively affect every aspect of hospice nurses' lives. Cognitive-behavioral sleep interventions show promise in teaching hospice nurses how to care for themselves by getting quality sleep. KNOWLEDGE TRANSLATION: Identifying the risks for sleep disturbances and depressive symptoms in hospice nurses will allow for effective, individualized interventions to help promote health and well-being. If hospice nurses achieve quality sleep, they may remain in the profession without suffering from chronic bereavement, which can result in compassion fatigue. A CBT-I intervention delivered at the agency and in a group format was feasible and acceptable by study participants.

Reduction in salivary α-amylase levels following a mind-body intervention in cancer survivors--an exploratory study.

OBJECTIVE: The main aim of this exploratory study was to assess whether salivary α-amylase (sAA) and salivary cortisol levels would be positively modulated by sleep-focused mind-body interventions in female and male cancer survivors. METHODS: We conducted a randomized controlled trial in which 57 cancer survivors with self-reported sleep disturbance received either a Sleep Hygiene Education (SHE; n=18) control, or one of two experimental mind-body interventions, namely, Mind-Body Bridging (MBB; n=19) or Mindfulness Meditation (MM; n=20). Interventions were three sessions each conducted once per week for three consecutive weeks. Saliva cortisol and sAA were measured at baseline and 1 week after the last session. Participants also completed a sleep scale at the same time points when saliva was collected for biomarker measurement. RESULTS: Our study revealed that at post-intervention assessment, mean sAA levels upon awakening ("Waking" sample) declined in MBB compared with that of SHE. Mean Waking cortisol levels did not differ among treatment groups but declined slightly in SHE. Self-reported sleep improved across the three interventions at Post-assessment, with largest improvements in the MBB intervention. CONCLUSION: In this exploratory study, sleep focused mind-body intervention (MBB) attenuated Waking sAA levels, suggesting positive influences of a mind-body intervention on sympathetic activity in cancer survivors with sleep disturbance.

Feasibility trial of electroacupuncture for aromatase inhibitor--related arthralgia in breast cancer survivors.

BACKGROUND: Arthralgia affects postmenopausal women receiving aromatase inhibitors (AIs) for breast cancer. Given the existing evidence for electroacupuncture (EA) for treatment of osteoarthritis in the general population, this study aims to establish the feasibility of studying EA for treating AI-related arthralgia. PATIENTS AND METHODS: Postmenopausal women with stage I-III breast cancer who reported AI-related arthralgia were enrolled in a single-arm feasibility trial. EA was provided twice a week for 2 weeks followed by 6 weekly treatments. The protocol was based on Chinese medicine diagnosis of "Bi" syndrome with electrostimulation of needles around the painful joint(s). Pain severity of the modified Brief Pain Inventory was used as the primary outcome. Joint stiffness, joint interference, and Patient Global Impression of Change (PGIC) were secondary outcomes. Paired t tests were used for analysis. RESULTS: Twelve women were enrolled and all provided data for analysis. From baseline to the end of intervention, patients reported reduction in pain severity (from 5.3 to 1.9), stiffness (from 6.9 to 2.4), and joint symptom interference (from 4.7 to 0.8), all P < .001; 11/12 considered joint symptoms "very much better" based on the PGIC. Subjects also reported significant decrease in fatigue (from 4.4 to 1.9, P = .005) and anxiety (from 7.1 to 4.8, P = .01). No infection or development or worsening of lymphedema was observed. CONCLUSION: Preliminary data establish the feasibility of recruitment and acceptance as well as promising preliminary safety and effectiveness. A randomized controlled trial is warranted to establish the efficacy of EA for AI-related arthralgia in breast cancer survivors.

Predictors of fatigue 30 days after completing anthracycline plus taxane adjuvant chemotherapy for breast cancer.

PURPOSES/OBJECTIVES: To identify the predictors of fatigue 30 days after completing adjuvant chemotherapy for breast cancer and whether differences are observed between a behavioral sleep intervention and a healthy-eating attention control group in predicting fatigue. DESIGN: Descriptive, exploratory, secondary analysis of a randomized clinical trial. SETTING: Outpatient oncology patients in a midwestern U. S. city. SAMPLE: 96 women, ages 29-83 years, 72% married, 95% white, diagnosed with stage I-IIIA breast cancer, receiving adjuvant anthracycline and taxane chemotherapy. METHODS: Participants were randomized to a behavioral sleep intervention group or an attention control group. Participants completed data collection prior to and during the peak and rebound days of the initial chemotherapy treatment cycle and after the last treatment. MAIN RESEARCH VARIABLES: Fatigue, circadian rhythms of activity, objective and subjective sleep-wake, and objective and subjective activity-rest. FINDINGS: Predictors of fatigue were less total sleep time prior to treatment, higher fatigue prior to treatment and at the peak, and less energy upon awakening on rebound days. In the control group, predictors of higher fatigue were higher fatigue prior to treatment, higher body mass index, higher number of positive lymph nodes, and less daytime dysfunction. For the intervention group, lower peak activity at the peak of initial treatment differentially predicted fatigue. CONCLUSIONS: Results suggest the sleep intervention group participants who maintained activity balanced with sleep at the peak of the initial treatment benefited most from the intervention. IMPLICATIONS FOR NURSING: Nurses should screen for fatigue prior to initial chemotherapy treatment and at regular intervals, further assess for poor sleep in patients who report fatigue of 4 or higher (on a 0-10 scale), and use evidence-based guidelines to select appropriate interventions.
