Sleep disturbance in adults with cancer: a systematic review of evidence for best practices in assessment and management for clinical practice

Prevalence and severity of sleep difficulty in patients with a CNS cancer receiving palliative care in Australia

Background

The literature describing the incidence of sleep difficulty in CNS cancers is very limited, with exploration of a sleep difficulty symptom trajectory particularly sparse in people with advanced disease. We aimed to establish the prevalence and longitudinal trajectory of sleep difficulty in populations with CNS cancers receiving palliative care nationally, and to identify clinically modifiable predictors of sleep difficulty.

Methods

A consecutive cohort of 2406 patients with CNS cancers receiving palliative care from sites participating in the Australian national Palliative Care Outcomes Collaboration were evaluated longitudinally on patient-reported sleep difficulty from point-of-care data collection, comorbid symptoms, and clinician-rated problems. Multilevel models were used to analyze patient-reported sleep difficulty.

Results

Reporting of mild to severe sleep difficulties ranged from 10% to 43%. Sleep scores fluctuated greatly over the course of palliative care. While improvement in patients' clinical status was associated with less sleep difficulty, the relationship was not clear when patients deteriorated. Worsening of sleep difficulty was associated with higher psychological distress (P < .0001), greater breathing problems (P < .05) and pain (P < .05), and higher functional status (P < .001) at the beginning of care.

Conclusions

Sleep difficulty is prevalent but fluctuates widely in patients with CNS cancers receiving palliative care. A better-tailored sleep symptom assessment may be needed for this patient population. Early interventions targeting psychological distress, breathing symptoms, and pain for more functional patients should be explored to see whether it reduces sleep difficulties late in life.

Incidence of sleep problems and their mediating role on depression and anxious preoccupation in patients with resected, non-advanced cancer: data from NEOcoping study

BACKGROUND

Our study analyzes the incidence of sleep problems and their mediating role on depression and anxious preoccupation in patients with resected, non-advanced cancer.

METHODS

A multi-institutional, prospective, observational study was conducted with 750 participants of 14 hospitals in Spain. Participants' socio-demographic and clinical characteristics were collected using a standardized self-report form and using EORTC QoL-QLQ-C30, BSI, Mini-MAC questionnaires.

RESULTS

In women, sleep problems, depression and anxious preoccupation were observed in 65, 41 and 21%, respectively. In men, sleep problems, depression and anxious preoccupation were reported in 51, 29 and 61%, respectively. More sleep problems, depression and anxious preoccupation were found among women than males. Depression was a significant predictor of anxious preoccupation. In males, sleep problems partially mediated this association. This was not confirmed in women.

CONCLUSION

Our findings point toward the importance of developing interventions that decrease depression and sleep problems in cancer.

Putting Integrative Oncology Into Practice: Concepts and Approaches

Unmet symptom needs and a desire for holistic health approaches or even cure are among the motivations patients have for seeking out complementary and alternative medicine. Using complementary and alternative medicine instead of conventional cancer treatment can have a negative impact on clinical outcomes and survival. Integrative oncology is a patient-centered, evidence-informed field of comprehensive cancer care that uses mind-body practices, natural products, and lifestyle modifications from different traditions alongside conventional cancer treatments. It prioritizes safety and best available evidence to offer appropriate therapeutic interventions along with conventional care. This review summarizes the underlying principles of integrative oncology and how it is distinct from alternative medicine, and it provides a practical guide for the effective application of evidence-based complementary and alternative medicine interventions in patient-centered care. In addition, we recommend resources for patients and clinicians and provide algorithms for appropriate integrative medicine referrals. Finally, we offer suggestions on developing and implementing an integrative oncology program and addressing current challenges in the field.

Psychodynamic Psychiatry for Patients with Cancer: Survivorship

The psychodynamic treatment approach for patients newly diagnosed with cancer provides a uniquely effective model for understanding the onset of psychiatric symptoms and planning a psychotherapeutic intervention. The words "you have cancer" often disrupt the patient's usual customary defenses and can result in the onset of psychiatric symptoms. The psychiatric symptoms will depend on the patient's usual defenses, past history, and characteristic style of relating to others. Multiple case examples of the cancer patient's journey from diagnosis to survivorship will be offered in this article to demonstrate the value of including a psychodynamic point of view in any treatment of cancer patients. This article will concern itself with patients who achieve survivorship.

Zopiclone versus placebo for short-term treatment of insomnia in patients with advanced cancer: study protocol for a double-blind, randomized, placebo-controlled, clinical multicenter trial

BACKGROUND

Despite the high prevalence of insomnia in patients with advanced cancer, there are no randomized controlled trials on pharmacological interventions for insomnia in this group of patients. A variety of pharmacological agents is recommended to manage sleep disturbance for insomnia in the general population, but their efficacy and safety in adults with advanced cancer are not established. Thus, there is a need to evaluate the effectiveness of medications for insomnia in order to improve the evidence in patients with advanced cancer. One of the most used sleep medications at present in patients with cancer is zopiclone.

METHODS

This is a randomized, double-blind, placebo-controlled, parallel-group, multicenter trial. A total of 100 patients with metastatic cancer who report insomnia will be randomly allocated to zopiclone or placebo. The treatment duration with zopiclone/placebo is 6 consecutive nights. The primary endpoint is patient-reported sleep quality during the final study night (night 6) assessed on a numerical rating scale of 0-10, where 0 = Best sleep and 10 = Worst possible sleep. Secondary endpoints include the mean patient-reported total sleep time and sleep onset latency during the final study night (night 6).

DISCUSSION

Results from this study on treatment of insomnia in advanced cancer will contribute to clinical decision-making and improve the treatment of sleep disturbance in this patient cohort.

Validity and feasibility of the Arabic version of distress thermometer for Saudi cancer patients

BACKGROUND

The distress thermometer (DT) has been studied and validated as an effective screening instrument for identifying distress among cancer patients worldwide. This study aims to evaluate the validity of the Arabic version of the DT in Saudi cancer patients, to define the optimal cutoff point of the Arabic DT for detecting clinically significant distress and to determine whether there is any correlation between clinically significant distress and other demographic and Problem List variables.

METHODS

The original form of the DT was translated to Arabic using a forward and backward translation method. Then, a group of 247 cancer patients who were followed up at the Outpatient Oncology Clinic at King Saud Medical City in Riyadh, Saudi Arabia, completed a socio-demographic and clinical status questionnaire, the DT and the Problem List scale, and the Hospital Anxiety and Depression Scale (HADS).

RESULTS

Receiver operating characteristic (ROC) curve analyses picked out an area under the curve of 0.76 when compared with a HADS cutoff score of 15. The DT had the best sensitivity (0.70) and specificity (0.63) with cutoff score of 4. A DT score of 4 or more was found to have a statistically significant correlation with female gender, advanced cancer stages and most of the Problem List items, including child care, work or school, treatment decision, dealing with children and partners, depression, fears, nervousness, sadness, loss of interest in usual activity, religious concerns, appearance, bathing/dressing, breathing, diarrhea, fatigue, feeling swollen, fever, getting around, indigestion, memory and concentration, nausea, dry nose, pain, and sexual problems. In contrast, a multivariate regression analysis confirmed only advanced cancer stages, treatment decision, depression, fear, sadness, worry, breathing, feeling swollen, fever, indigestion, memory and concentration, dry nose and congestion, pain and sleep as independent factors associated with distress in cancer patients.

CONCLUSIONS

We found the Arabic version of the DT to be a valid instrument for screening distress in Saudi patients with cancer. Our study proposes using a cutoff score of 4 as an indicator of clinically significant distress in this population.

Internet-Delivered Cognitive-Behavioral Therapy for Insomnia in Breast Cancer Survivors: A Randomized Controlled Trial

Background

Insomnia is two to three times more prevalent in cancer survivors than in the general population, where it is estimated to be 10% to 20%. Cognitive-behavioral therapy for insomnia (CBT-I) is the recommended treatment for chronic insomnia, but meeting survivor needs remains a challenge. Internet-delivered CBT-I (iCBT-I) has been shown efficacious in otherwise healthy adults. We tested the efficacy of iCBT-I in breast cancer survivors with clinically significant sleep disturbance.

Methods

Women from a national sample of Danish breast cancer survivors who experienced clinically significant sleep disturbance were randomly allocated to iCBT-I or waitlist control (55:45). The fully automated iCBT-I program consisted of six cores. Online measures of insomnia severity, sleep quality, and fatigue were collected at baseline, postintervention (nine weeks), and follow-up (15 weeks). Online sleep diaries were completed over two-week periods pre- and postintervention. Intention-to-treat analyses (time × group interactions) were conducted with mixed linear models and corrected for multiple outcomes. All statistical tests were two-sided.

Results

A total of 255 women were randomly allocated to iCBT-I (n = 133) or waitlist control (n = 122). Statistically significant (P ≤ .02) time × group interactions were found for all sleep-related outcomes from pre- to postintervention. Effect sizes (Cohen's d) ranged from 0.33 (95% confidence interval [CI] = 0.06 to 0.61) for wake after sleep onset to 1.17 (95% CI = 0.87 to 1.47) for insomnia severity. Improvements were maintained for outcomes measured at follow-up (d = 0.66-1.10).

Conclusions

iCBT-I appears to be effective in breast cancer survivors, with additional benefit in terms of reduced fatigue. This low-cost treatment could be incorporated in cancer rehabilitation programs.

Sleep quality with WHO Step III opioid use for cancer pain

OBJECTIVE

Sleep is often disturbed in patients with advanced cancer. There is limited knowledge about sleep in patients with cancer treated with strong opioids. This study examines sleep quality in patients with advanced cancer who are treated with a WHO Step III opioid for pain.

METHODS

An international, multicentre, cross-sectional study with 604 adult patients with cancer pain using WHO Step III opioids. Sleep quality was assessed by the Pittsburgh Sleep Quality Index (PSQI) global score (range; 0-21; score >5 indicates poor sleep). PSQI includes sleep quality, sleep latency, sleep duration, sleep efficiency, sleep disturbances, use of sleep medications and daytime dysfunction. Pain and quality of life were assessed by Brief Pain Inventory and European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core30.

RESULTS

The median age was 62 years, 42% were female, mean Karnofsky performance score (KPS) was 62.5 (±14.2) and mean oral daily morphine equivalent dose was 303 mg/24 hours (±543.8 mg). The mean PSQI global score was 8.8 (±4.2) (range 0-20). Seventy-eight per cent were poor sleepers. All PSQI components were affected, and 44% reported trouble sleeping caused by pain. In the multiple regression model, predictors of PSQI global scores were pain intensity, emotional function, constipation, financial difficulties and KPS (adjusted R²=0.21).

CONCLUSION

The majority (78%) of these patients with cancer treated with Step III opioids experienced poor sleep quality. Pain intensity, emotional function, constipation, financial difficulties and KPS predicted poor PSQI global scores. The clinical implication is that healthcare personnel should routinely assess and treat sleep disturbance in patients with advanced cancer disease.

Sleep disorder diagnoses and clinical outcomes among hospitalized breast cancer patients: a nationwide inpatient sample study

PURPOSE

Sleep disturbances are recognized as a problem for many cancer patients, but little is known about the prevalence of sleep disorders among women hospitalized with breast cancer, or their relationship to in-hospital outcomes. The present study represents a first step toward determining the clinical significance of sleep disorders for hospitalized breast cancer patients with regard to complications, length of hospital stay, and mortality.

METHODS

The relationships between sleep disorders and in-hospital outcomes among 84,424 hospitalized breast cancer patients were examined. This study analyzed the Nationwide Inpatient Sample (NIS) database (2007 to 2011) for all women ages 40 years and older with a primary discharge diagnosis of breast cancer and a secondary discharge diagnosis of sleep disorder. Odds ratios, estimates, and 95% confidence intervals were computed using multivariable regression adjusting for age, comorbidities, race, cancer stage, income, insurance type, residential region, year of discharge, and surgical treatment type.

RESULTS

Among women hospitalized with a primary diagnosis of breast cancer, 2% (n = 1807) also received a diagnosis of a sleep disorder during hospitalization, the majority of which were sleep-related breathing disorders (n = 1274). Although there was no significant association between having a diagnosis of a sleep disorder and in-hospital mortality, patients with a sleep disorder were more likely to also experience complications (OR = 1.58, 95% CI 1.29-1.34) and have longer hospital stays (mean = 0.44 days longer, 95% CI 0.25-0.63).

CONCLUSION

Hospitalized breast cancer patients with a sleep disorder were more likely to experience clinical complications and stay longer in the hospital. It remains an open and important question for future research whether interventions to improve sleep during hospitalization would help to improve clinical outcomes.

Sleep disturbance of adults with a brain tumor and their family caregivers: a systematic review

The high incidence and psychophysiological morbidities of sleep disturbance in cancer have been increasingly recognized. Yet, more detailed understanding of sleep disturbance and options for management have been neglected areas in both clinical care and research. Brain tumor patients have been particularly overlooked. A systematic search of the literature from 1990 to 2015 was performed to review sleep disturbance in adults with primary or secondary brain tumor and their family caregivers. Fifty eligible studies were identified, of which 12 focused on sleep, 37 reported sleep items within a health-related quality of life measure and 1 reported caregivers' sleep. No sleep intervention has been developed or tested for brain tumor patients. Sleep disturbance and somnolence were frequently reported as the most severely rated symptoms within health-related quality of life across the disease course or treatments, along with fatigue. However, sleep-focused studies yielded inconsistent results in small samples of mostly benign brain tumors in long-term remission from total tumor resection. The research using standardized, multifaceted sleep assessments, particularly in patients with malignant brain tumor and caregivers who are undergoing treatment, is seriously lacking. A more systematic examination of sleep disturbance is warranted to inform the development of better symptom management programs in this population.

Nonpharmacologic Interventions for Improving Sleep Disturbances in Patients With Lung Cancer: A Systematic Review and Meta-analysis

CONTEXT

Lung cancer patients experience higher levels of sleep disturbances compared to other cancer patients, and this leads to greater distress, poorer function, and lower quality of life. Nonpharmacologic interventions have demonstrated improvements in the context of breast cancer, but their efficacy in the lung cancer population is unclear.

OBJECTIVES

The aim of this review was to determine the effects of any nonpharmacologic intervention on sleep quality of lung cancer patients.

METHODS

Intervention studies of any design that reported primary or secondary outcomes on sleep quality were included. Databases searched were Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, and PsycINFO. Risk of bias was assessed regarding randomization, allocation concealment, blinding, incomplete outcome data, selective reporting, and other biases.

RESULTS

Twenty-two studies were identified with a total of 1272 participants. Pittsburgh Sleep Quality Index was the most common instrument used. Statistically significant results were observed for all intervention categories examined in the short-term follow-up period: exercise and rehabilitation programs (standardized mean difference [SMD]: -0.43, 95% CI: -0.68, -0.19, P = 0.0005); information, psychoeducation, and symptom screening interventions (SMD: -0.87, 95% CI: -1.21, -0.54, P < 0.00001); and mind-body interventions (SMD: -0.88, 95% CI: -1.59, -0.16, P = 0.02). However, effectiveness was lower and nonsignificant when evaluated over one month after completion.

CONCLUSION

Limitations include the high heterogeneity of interventions and outcome measures, in addition to small sample sizes and high risk of bias within studies. Because they do not allow for a clear interpretation of the results, it is recommended that every patient should be assessed individually to guide a possible referral.

An Integrative Review of Nonpharmacological Interventions to Improve Sleep among Adults with Advanced Serious Illness

BACKGROUND

Sleep fragmentation is common among those with advanced serious illness. Nonpharmacological interventions to improve sleep have few, if any, adverse effects and are often underutilized in these settings.

OBJECTIVE

We aimed to summarize the literature related to nonpharmacological interventions to improve sleep among adults with advanced serious illness.

METHODS

We systematically searched six electronic databases for literature reporting sleep outcomes associated with nonpharmacological interventions that included participants with advanced serious illness during the period of 1996-2016.

RESULTS

From a total of 2731 results, 42 studies met the inclusion criteria. A total of 31 individual interventions were identified, each evaluated individually and some in combination with other interventions. Twelve of these studies employed either multiple interventions within an intervention category (n = 8) or a multicomponent intervention consisting of interventions from two or more categories (n = 5). The following intervention categories emerged: sleep hygiene (1), environmental (6), physical activity (4), complementary health practices (11), and mind-body practices (13). Of the 42 studies, 22 demonstrated a statistically significant, positive impact on sleep and represented each of the categories. The quality of the studies varied considerably, with 17 studies classified as strong, 17 as moderate, and 8 as weak.

CONCLUSIONS

Several interventions have been demonstrated to improve sleep in these patients. However, the small number of studies and wide variation of individual interventions within each category limit the generalizability of findings. Further studies are needed to assess interventions and determine effectiveness and acceptability.

Sleep Quality, Sleep Duration, and the Risk of Coronary Heart Disease: A Prospective Cohort Study With 60,586 Adults

STUDY OBJECTIVES

There is limited information on the relationship between risk of cardiovascular disease and the joint effects of sleep quality and sleep duration, especially from large, prospective, cohort studies. This study is to prospectively investigate the joint effects of sleep quality and sleep duration on the development of coronary heart disease.

METHODS

This study examined 60,586 adults aged 40 years or older. A self-administered questionnaire was used to collect information on sleep quality and sleep duration as well as a wide range of potential confounders. Events of coronary heart disease were self-reported in subsequent medical examinations. Two types of Sleep Score (multiplicative and additive) were constructed to reflect the participants' sleep profiles, considering both sleep quality and sleep duration. The Cox regression model was used to estimate the hazard ratio (HR) and the 95% confidence interval (CI).

RESULTS

A total of 2,740 participants (4.5%) reported new events of coronary heart disease at follow-up. For sleep duration, participants in the group of < 6 h/d was significantly associated with an increased risk of coronary heart disease (HR: 1.13, 95% CI: 1.04-1.23). However, the association in the participants with long sleep duration (> 8 h/d) did not reach statistical significance (HR: 1.11, 95% CI: 0.98-1.26). For sleep quality, both dreamy sleep (HR: 1.21, 95% CI: 1.10-1.32) and difficult to fall asleep/use of sleeping pills or drugs (HR: 1.40, 95% CI: 1.25-1.56) were associated with an increased risk of the disease. Participants in the lowest quartile of multiplicative Sleep Score (HR: 1.31, 95% CI: 1.16-1.47) and of additive sleep score (HR: 1.31, 95% CI: 1.16-1.47) were associated with increased risk of coronary heart disease compared with those in the highest quartile.

CONCLUSIONS

Both short sleep duration and poor sleep quality are associated with the risk of coronary heart disease. The association for long sleep duration does not reach statistical significance. Lower Sleep Score (poorer sleep profile) increases the risk of coronary heart disease, suggesting the importance of considering sleep duration and sleep quality together when developing strategies to improve sleep for cardiovascular disease prevention.

Trajectory of sleep disturbances in patients undergoing lung cancer surgery: a prospective study

OBJECTIVES

Patients with lung cancer report sleep difficulties to be frequent and bothersome symptoms. This study describes the trajectory of sleep from before and up to 12 months after surgery for lung cancer. Further, it investigates possible associations between sleep disturbance, demographic and clinical characteristics before surgery.

METHODS

This study is part of a longitudinal multicentre study. Sleep disturbance was measured by The General Sleep Disturbance Scale (GSDS) that investigates frequencies of sleep difficulties (21 items) and a total sum score ≥43 indicates a clinically meaningful level of sleep disturbance (score range 0-147). Linear mixed models were used to study changes in sleep from baseline to 1, 5, 9 and 12 months after surgery.

RESULTS

The percentage of patients (n = 264) reporting sleep disturbances was 60.9% at baseline, 68.5% at Month 1, 55.4% at Month 5, 51.3% at Month 9 and 49.7% at Month 12. The increase to and decrease from Month 1 was the only significant alteration in the occurrence of sleep disturbance. The patients reported most problems within the subscales sleep quantity, early awakenings and sleep quality. Factors associated with sleep disturbance were lower age, use of pain medication and psychotropic medication and higher comorbidity score.

CONCLUSIONS

Lung cancer patients sleep poorly, before as well as after surgery. There is a need to address sleeping disturbance routinely in clinical practice and screening for sleeping problems is indicated. Further studies are warranted concerning factors that contribute to sleep disturbance and how they best can be treated.

FORECAST - A cloud-based personalized intelligent virtual coaching platform for the well-being of cancer patients

•

The challenges of cancer patients and the benefits of coaching are presented.

•

Evidence of impact of coaching on the well being of cancer patients is presented.

•

A cloud-based personalized intelligent virtual coaching platform for the well-being of cancer patients is proposed.

•

Technology acceptance of the platform is presented, based on validation trials.

•

Future work is discussed.

Well-being of cancer patients and survivors is a challenge worldwide, considering the often chronic nature of the disease. Today, a large number of initiatives, products and services are available that aim to provide strategies to face the challenge of well-being in cancer patients; nevertheless the proposed solutions are often non-sustainable, costly, unavailable to those in need, and less well-received by patients. These challenges were considered in designing FORECAST, a cloud-based personalized intelligent virtual coaching platform for improving the well-being of cancer patients. Personalized coaching for cancer patients focuses on physical, mental, and emotional concerns, which FORECAST is able to identify. Cancer patients can benefit from coaching that addresses their emotional problems, helps them focus on their goals, and supports them in coping with their disease-related stressors. Personalized coaching in FORECAST offers support, encouragement, motivation, confidence, and hope and is a valuable tool for the wellbeing of a patient.

Effects of mindfulness-based psychological care on mood and sleep of leukemia patients in chemotherapy

PURPOSE

The aim of this research was to explore the benefits of mindfulness-based psychological care (MBPC) and assess whether the intervention would be beneficial in reducing insomnia and emotional symptoms of leukemia patients receiving chemotherapy.

METHODS

A randomized control design study was applied in two hematology departments in a hospital in Zhengzhou. Patients in the experimental group received mindfulness-based psychological care(MBPC), and those in the control group received conventional care. Anxiety, depression, and sleeping problems were measured using the Self-Rating Anxiety Scale, Self-Rating Depression Scale, and the Pittsburgh Sleep Quality Index.

RESULTS

Statistically significant differences were observed among anxiety, depression, and sleeping problems between the two groups in the post-test (P < 0.05). A significant decrease in anxiety and depression and an improvement in sleep were observed between pre- and post-interventions (P < 0.05) in the experimental group.

CONCLUSIONS

MBPC significantly improved sleep quality and mood of the experimental group. It is an effective complementary therapy for leukemia treatment that is inexpensive, noninvasive, and associated with relaxation and pain reduction.

Tai Chi Chih Compared With Cognitive Behavioral Therapy for the Treatment of Insomnia in Survivors of Breast Cancer: A Randomized, Partially Blinded, Noninferiority Trial

Purpose Cognitive behavioral therapy for insomnia (CBT-I) and Tai Chi Chih (TCC), a movement meditation, improve insomnia symptoms. Here, we evaluated whether TCC is noninferior to CBT-I for the treatment of insomnia in survivors of breast cancer. Patients and Methods This was a randomized, partially blinded, noninferiority trial that involved survivors of breast cancer with insomnia who were recruited from the Los Angeles community from April 2008 to July 2012. After a 2-month phase-in period with repeated baseline assessment, participants were randomly assigned to 3 months of CBT-I or TCC and evaluated at months 2, 3 (post-treatment), 6, and 15 (follow-up). Primary outcome was insomnia treatment response-that is, marked clinical improvement of symptoms by the Pittsburgh Sleep Quality Index-at 15 months. Secondary outcomes were clinician-assessed remission of insomnia; sleep quality; total sleep time, sleep onset latency, sleep efficiency, and awake after sleep onset, derived from sleep diaries; polysomnography; and symptoms of fatigue, sleepiness, and depression. Results Of 145 participants who were screened, 90 were randomly assigned (CBT-I: n = 45; TCC: n = 45). The proportion of participants who showed insomnia treatment response at 15 months was 43.7% and 46.7% in CBT-I and TCC, respectively. Tests of noninferiority showed that TCC was noninferior to CBT-I at 15 months ( P = .02) and at months 3 ( P = .02) and 6 ( P < .01). For secondary outcomes, insomnia remission was 46.2% and 37.9% in CBT-I and TCC, respectively. CBT-I and TCC groups showed robust improvements in sleep quality, sleep diary measures, and related symptoms (all P < .01), but not polysomnography, with similar improvements in both groups. Conclusion CBT-I and TCC produce clinically meaningful improvements in insomnia. TCC, a mindful movement meditation, was found to be statistically noninferior to CBT-I, the gold standard for behavioral treatment of insomnia.

The relationship of perfectionism with psychological symptoms in cancer patients and the contributing role of hyperarousability and coping

OBJECTIVE

Significant levels of anxiety, depression and insomnia symptoms are found in cancer patients. Perfectionism, arousability and coping have been associated with these psychological symptoms in the general population but their role among cancer patients remains to be assessed. This study examined the longitudinal relationships between perfectionism and psychological symptoms (anxiety, depression, insomnia), and the intermediate role of the arousability trait and coping strategies.

DESIGN

Participants (N = 853) completed the Multidimensional Perfectionism Scale, the Coping with Health Injuries and Problems questionnaire and the Arousal Predisposition Scale at the perioperative period (T1), and the Hospital Anxiety and Depression Scale and the Insomnia Severity Index two months later (T2).

RESULTS

Higher levels of perfectionism (T1) were correlated with greater symptoms of anxiety, depression and insomnia (T2). Moderated mediation models indicated that arousability contributed to the association of perfectionism with all symptoms, with stronger associations found in men than in women. Coping was a significant pathway between perfectionism and anxiety, with associations of a comparable magnitude across sexes.

CONCLUSION

If these results are replicated by future longitudinal studies, they would suggest that perfectionist cancer patients are at a higher risk of experiencing psychological symptoms, partly through their hyperarousability and the coping strategies they use.

Knowledge and attitudes of primary care nurses about the management of patients with insomnia

OBJECTIVE

To describe the knowledge, attitudes, and performance of primary care nurses in the management of patients with insomnia.

METHODS

Descriptive study. An online questionnaire was sent to all primary care nurses of the Majorca Primary Care Department between June-July 2014.

MEASUREMENTS

sociodemographic variables, professional characteristics, tuition, usual clinical practice in the management of patients with insomnia.

RESULTS

138 nurses answered the questionnaire (47%). Most of them were women (92.8%), 50.42 years old (DE=8.9). The majority considered insomnia an important health problem. Only 11% had received some formative activity on insomnia in the last 5 years. Nearly half declares to ask patients about consequences of insomnia in their jobs and about habits that alter their sleep quality. 79.7% considered the possible adverse effects of insomnia drugs and take into consideration the age of patient (80.4%). The usual treatments were sleep hygiene (76%), phytotherapy (44.9%) and 22.4% cognitive behavioral therapy (CBT). This therapy is considered effective and applicable by nurses (63.7%) and doctors (58%). Those nurses who attended courses in the last 5 years apply CBT more frequently.

CONCLUSIONS

Nurses conduct a correct anamnesis and evaluation of patients with insomnia. However some therapies of known effectiveness, such as CBT, are still scarcely applied.

Improving sleep-wake disturbances in patients with cancer

Patients with cancer tend to suffer sleep-wake disturbances at a higher rate than the general population. Insomnia and fatigue should be regarded as a significant patient safety issue, as poor sleep can elevate patients' risks of falls, motor vehicle accidents, and acute infectious illnesses. To alleviate those risks, oncology nurses should be familiar with effective evidence-based practices for assessing and improving patients' sleep quality.

The Efficacy of Oral Melatonin in Improving Sleep in Cancer Patients with Insomnia: A Randomized Double-Blind Placebo-Controlled Study

BACKGROUND

The natural hormone melatonin has sleep inducing properties. Insomnia in cancer patients is common. So far, melatonin has been seldom tried for the improvement of sleep in patients with malignancies. Keeping this in mind, we planned and conducted a double-blind study to test the efficacy of melatonin in promoting sleep in patients with malignancies suffering from insomnia.

OBJECTIVE

To assess the hypnotic efficacy of oral melatonin in cancer patients with insomnia.

MATERIALS AND METHODS

After Ethical Committee approval, 50 patients (age range 20-65 years) from our pain clinic NIVARANE who met the Diagnostic and Statistical Manual of Mental Disorders 4(th) edition criteria for primary insomnia were randomized to receive melatonin 3 mg or placebo at 7 pm orally every day for 14 days from our pharmacist. After 1, 7, 14 days, the patients were reviewed with the Athens insomnia scale oral questionnaire to document the subjective sleep quality. The patients and we, the investigators were blinded to the study drug.

RESULTS

There were 2 drop outs (one from each group) as they failed to complete visit on day 14. Significant differences in favor of melatonin treatment were found in clinically relevant improvements in insomnia (46.53%; P = 0.00001 vs. 11.30%; P = 0.1026) There was improvement in sleep from 1 to 7 days (19.91%; P = 0.00001 vs. 0.98%; P = 0.2563). More significant improvements were seen between 7 and 14 days (33.24%; P = 0.00001 vs. 10.42%; P = 0.1469).

CONCLUSION

We conclude that daily intake of oral melatonin 2 h before bedtime improves sleep induction and quality in cancer patients with insomnia.

Sleep Patterns During Hospitalization Following Hematopoietic Stem Cell Transplantation

PURPOSE/OBJECTIVES

To characterize patient-reported and objective sleep assessments and provide a preliminary examination of the relationships among sleep, quality of life, and demographic or treatment factors.

DESIGN

A secondary data analysis using a descriptive-correlational design.

SETTING

University of Illinois Hospital and Health Sciences System.

SAMPLE

40 patients undergoing a hematopoietic stem cell transplantation (HCT) hospitalized for the conditioning regimen, stem cell infusion, and immediate recovery period.

METHODS

Each patient wore a wrist actigraph continuously from the fourth day following HCT to the eighth day to objectively assess sleep patterns (total sleep time, sleep onset latency, sleep efficiency, wake after sleep onset, and number of awakenings). At the end of the five-day period, patients completed measures of sleep disturbance and quality of life.

MAIN RESEARCH VARIABLES

Objective sleep (total sleep time, sleep onset latency, sleep efficiency, wake after sleep onset, and number of awakenings), subjective sleep (sleep disturbance), and quality of life.

FINDINGS

The mean total nighttime sleep (objectively obtained) was 232 minutes (SD = 71 minutes), with 14 patients (35%) sleeping less than three consecutive hours during one or more study days. Age was negatively correlated with patient-reported sleep disturbance. Patient-reported sleep disturbance was significantly associated with length of hospital stay. No correlations were found between patient-reported and objective sleep assessments.

CONCLUSIONS

This study objectively documents inadequate and irregular sleep in hospitalized patients undergoing HCT. Sole reliance on patient-reported sleep assessments may not represent the full extent of the problem.

IMPLICATIONS FOR NURSING

Attempts to streamline care during the night by not waking patients for routine care unless indicated by the patient's condition (as advocated by the American Academy of Nursing) and providing supportive care for symptoms (such as diarrhea) during the night may reduce the number of awakenings and possibly improve overall sleep quality.

Sleep Disturbances in Acutely Ill Patients with Cancer

Intensive care units may place acutely ill patients with cancer at additional risk for sleep loss and associated negative effects. Research suggests that communication about sleep in patients with cancer is suboptimal and sleep problems are not regularly assessed or adequately treated throughout the cancer trajectory. However, many sleep problems and fatigue can be managed effectively. This article synthesizes the current literature regarding the prevalence, cause, and risk factors that contribute to sleep disturbance in the context of acute cancer care. It describes the consequences of poor sleep and discusses appropriate assessment and treatment options.

Relationship Between Sleep Quality and Spiritual Well-Being/Religious Activities in Muslim Women with Breast Cancer

For determining relationship between quality of sleep and spiritual well-being/religious activities in Muslim women with breast cancer (WBC), we conducted a cross-sectional study on 80 WBC who presented at all chemotherapy clinics in Qom, Iran, in 2012. We used Pittsburgh Sleep Quality Index (PSQI), spiritual well-being scale (SWBS), and religious activities (RA) questionnaire. Global PSQI score and its seven components score were not significantly correlated with total score of SWBS and its two subscales. Global PSQI score was not significantly correlated with total score of RA questionnaire (P = 0.278), but its "sleep latency" (r = 0.235, P = 0.044) and "use of sleep medications" (r = 0.237, P = 0.040) components were significantly correlated with total score of RA. Global PSQI was significantly correlated with "I don't get much personal strength and support from my God," "I believe there is some real purpose for my life" questions in SWBS, and "Attendance in mosque or religious places" subscale of RA.

Sleep Disturbances in Patients with Medical Conditions

Sleep-wake cycle disturbances are prevalent in patients with medical conditions and frequently present as part of a symptom cluster. Sleep disturbances impair functioning and quality of life, decrease adherence to treatments of the primary medical condition, and increase morbidity and mortality. The pathophysiology of sleep disturbances in these patients involves alterations in immune and neuroendocrine function and shares common pathophysiologic pathways with comorbidities such as fatigue and depression. Emphasis is placed on the evaluation and management of medical and psychiatric comorbidities and other factors contributing to sleep problems. Primary treatments include cognitive-behavioral therapy and pharmacotherapy.

Psychiatric considerations in the oncology setting

An aging population and advances in diagnostics and treatment have resulted in a rapidly growing population of people impacted by cancer. People live longer after a cancer diagnosis and tolerate more aggressive treatments than in the past. Younger patients struggle with diversions from the normal developmental milestones in career and relationships, while older patients deal with the dual challenges of aging and cancer. Cancer's transition from likely death to survival has increased interest in its impact on psychosocial issues and quality of life, rather than just longevity. In this article, the authors review the psychiatric diagnosis and management of the mental health issues most often encountered in oncology. Oncology treatment teams, including oncologists, nurses, social workers, and other ancillary staff, are often on the front lines of addressing psychiatric distress and clinical syndromes when psychiatrists are not easily available. The purpose of this review article is to highlight opportunities for nonpsychiatrists to improve identification and treatment of psychosocial distress and psychiatric syndromes and to request formal psychiatric consultation in appropriate situations. Psychotherapeutic, psychopharmacologic, cognitive, and behavioral-oriented interventions, as well as supportive interventions, are discussed for treating patients who are facing challenges during active cancer treatment, survivorship, and at the end of life. This review is not exhaustive but highlights the more common psychosomatic medicine and palliative care scenarios that impact cancer patient care. The importance of recognizing and addressing burnout and compassion fatigue in multidisciplinary professionals who care for those treated for cancer is also discussed given the secondary impact this can have on patient care.

Screening, evaluation, and management of cancer-related fatigue: Ready for implementation to practice?

Answer questions and earn CME/CNE Evidence regarding cancer-related fatigue (fatigue) has accumulated sufficiently such that recommendations for screening, evaluation, and/or management have been released recently by 4 leading cancer organizations. These evidence-based fatigue recommendations are available for clinicians, and some have patient versions; but barriers at the patient, clinician, and system levels hinder dissemination and implementation into practice. The underlying biologic mechanisms for this debilitating symptom have not been elucidated completely, hindering the development of mechanistically driven interventions. However, significant progress has been made toward methods for screening and comprehensively evaluating fatigue and other common symptoms using reliable and valid self-report measures. Limited data exist to support the use of any pharmacologic agent; however, several nonpharmacologic interventions have been shown to be effective in reducing fatigue in adults. Never before have evidence-based recommendations for fatigue management been disseminated by 4 premier cancer organizations (the National Comprehensive Cancer, the Oncology Nursing Society, the Canadian Partnership Against Cancer/Canadian Association of Psychosocial Oncology, and the American Society of Clinical Oncology). Clinicians may ask: Are we ready for implementation into practice? The reply: A variety of approaches to screening, evaluation, and management are ready for implementation. To reduce fatigue severity and distress and its impact on functioning, intensified collaborations and close partnerships between clinicians and researchers are needed, with an emphasis on system-wide efforts to disseminate and implement these evidence-based recommendations.

Incorporating measures of sleep quality into cancer studies

INTRODUCTION/BACKGROUND

Sleep disturbance may influence the development of cancer and responses to treatment. It is also closely tied to recovery and quality of life in cancer patients, survivors, and caregivers, and recent studies have begun to show beneficial effects of sleep-promoting interventions. Despite the importance of sleep to cancer and its treatment and the availability of numerous tools for measuring sleep quality and quantity, sleep measurements are underutilized in cancer studies.

METHODS

This review, written for cancer researchers interested in incorporating sleep measures into their studies, is designed to raise awareness about the importance of sleep and suggests strategies for including sleep evaluation in cancer studies.

CONCLUSIONS

Inclusion of readily available sleep measures may ultimately improve cancer care by facilitating studies that lead to a greater understanding of how sleep and sleep disturbance influence all aspects of cancer care and the patient experience.
