Sensitivity and specificity of proposed Richards-Campbell Sleep Questionnaire cut-off scores for good quality sleep during an ICU stay.

BACKGROUND: The 5-visual analogue scale Richards-Campbell Sleep Questionnaire subjective sleep measure is widely used in intensive care. A cut-off score indicative of good quality sleep has not been established and is required to guide the categorisation of individual patient and unit wide sleep quality. DESIGN AND METHODS: The aim was to determine the global Richards-Campbell Sleep Questionnaire cut-off score for good to very good sleep during an intensive care unit stay in non-ventilated patients. The study was a secondary (cohort) retrospective analysis of patient self-report data (n = 32) from an interventional study testing a sleep promotion bundle. The Standards for Reporting Diagnostic Accuracy studies statement were used to report the study. The study was conducted in two mixed adult 12 and 20-bed ICUs of a tertiary referral hospital in a metropolitan area. In the morning, eligible patients were administered the Richards-Campbell Sleep Questionnaire together with a 5-category item Likert scale in which patients rated their nocturnal sleep quality as 'very poor', 'poor', 'fair', 'good' and 'very good'. Receiver Operator Curve analysis was performed. RESULTS: Thirty-seven per cent (n = 32) of the total sample of 84 adult intensive care patients were females. The median age was 61.5 (51, 72) years. Self-reported median global Richards-Campbell Sleep Questionnaire score was 54.4 (30.1, 77.1) mm. A global score of ≥63.4 mm was the optimal cut-off for self-reported 'good sleep' (sensitivity: 87%, specificity: 81% and area under the curve: 0.896). CONCLUSIONS: Although the study requires replication in ventilated patients and other ICU settings, the cut-off score (63 mm) could be used to guide the categorisation of individual patient and unit wide sleep quality.

Sleep improvement intervention and its effect on patients' sleep on the ward.

AIM AND OBJECTIVE: The aim of the study was to investigate how the sleep improvement interventions developed for the wards were associated with patients' sleep. The objective was to promote patients' sleep. BACKGROUND: The quality of sleep is vital for patients' health and recovery from illness. However, patients generally sleep poorly during hospitalisation. Sleep-disturbing factors are connected to the hospital environment, patients' physical illness, emotional state and the activities of the staff. Many sleep-disturbing factors can be influenced by appropriate nursing interventions. DESIGN: A two-group intervention study including the development of nursing interventions aimed at supporting patients' sleep. One group received a sleep promotion intervention and the other received standard care. Both groups evaluated their sleep in the morning. METHODS: A survey of participants' sleep evaluations was collected with the five-item Richards-Campbell Sleep Questionnaire. The data were analysed statistically. The STROBE checklist was used to report the study. RESULTS: From the participants' perspective, sleep was better in the intervention group, even though statistically significantly only among men. The pain intensity correlated with sleep quality. The number of patients in the room or whether participants had had an operation had no effect on their sleep evaluations. CONCLUSIONS: Interventions targeted at supporting and promoting the sleep quality of hospital inpatients may be effective. They should be developed in collaboration with patients and nurses. Several nursing interventions can be proposed to promote better sleep among patients; however, more research is needed to confirm the results. Sleep promotion should include both standardised protocols and individualised sleep support. RELEVANCE TO CLINICAL PRACTICE: Investing in nursing interventions to promote patients' sleep is important. Patients' individual sleep-related needs should be part of their care plan. Training programmes that support nurses' knowledge and skills of patients' sleep promotion should be part of nursing education in healthcare organisations.

Investigating the construct and concurrent validity of the Richards-Campbell Sleep Questionnaire with intensive care unit patients and home sleepers.

BACKGROUND: Sleep is vital to our wellbeing. Critically ill patients are vulnerable with effects of sleep deprivation including weakened immune function, decreased glucose tolerance, and increased sympathetic activity. Intensive care unit (ICU) patients' sleep evaluation is difficult and often not reliable. The most commonly used instrument for assessing ICU patients' perspective of their sleep, Richards-Campbell Sleep Questionnaire (RCSQ), has not been reported to have undergone known-group construct validity testing or concurrent validity testing with the criterion measure of feeling refreshed. OBJECTIVES: The aim of the study was to explore the construct validity of the RCSQ with known-groups technique and concurrent validity with the criterion measure of feeling refreshed on awakening. METHODS: A cross-sectional descriptive survey study using the RCSQ was conducted on people sleeping at home (n = 114) over seven nights. The results were compared with the RCSQ sleep scores of nonintubated alert oriented adult ICU patients (n = 114). Home sleepers were also asked to rate how refreshed they felt on awakening. The study was executed and reported in accordance with the STROBE checklist for observational studies. FINDINGS: RCSQ construct validity was supported because home sleepers' and ICU sleepers' sleep evaluations differed significantly. Home sleepers rated their sleep significantly better than ICU patients in all five sleep domains of the RCSQ. Concurrent validity was supported because the item "feeling refreshed on awakening" correlated strongly with all sleep domains. CONCLUSIONS: Sleep quality may be accurately measured using the RCSQ in alert people both in the ICU and at home. This study has added to the validity discussion around the RCSQ. The RCSQ can be used for sleep evaluation in ICUs to promote wellbeing and recovery.

Empowering patient education on self-care activity among patients with colorectal cancer - a research protocol for a randomised trial.

BACKGROUND: Chemotherapy-induced side effects may have a negative effect on nutrition intake, thus increasing the risk of malnutrition and consequently, other serious complications for patients with cancer. The prevalence of malnutrition is common among patients with colorectal cancer. Nurse-led empowering education may have a positive effect on self-care activity in this patient group. Therefore, our purpose is to develop an empowering educational nursing intervention and test its effect on self-care activation and knowledge level among patients with colorectal cancer during chemotherapy. Secondary outcomes are quality of life and risk of malnutrition. METHODS: An interdisciplinary expert group developed a face-to-face empowering educational intervention using teach-back method. A two-arm, single-centre, superiority trial with stratified randomisation (1:1) and pre-post measures will be used to assess the effect of the intervention compared to standard care. Patients (N = 40 + 40) will be recruited in one university hospital outpatient clinic in Finland. Eligibility criteria are adult patients diagnosed with colorectal cancer starting oral fluoropyrimidine or combination chemotherapy treatment. A registered nurse experienced in oncology will deliver the intervention 2 weeks after the first chemotherapy. Outcomes are measured before intervention (M0) and after a two-month follow-up period (M1). DISCUSSION: This study will assess whether nurse-led empowering education using teach-back method is effective on self-care activity among patients with colorectal cancer. If the intervention has a positive effect, it may be implemented into patient education in a corresponding context. TRIAL REGISTRATION: ClinicalTrials.gov : NCT04160650 Registered 12 November 2019 - retrospectively registered.

Anaesthesia nursing competence: Self-assessment of nursing students.

BACKGROUND: The importance of competence assessment in anaesthesia nursing education has increased since nurse educators and anaesthesia care employers have identified the gap between nursing education and nursing practice. In order to ensure nursing students' preparedness for entry into anaesthesia nursing practice, it is necessary to measure whether nursing students have achieved the required competence to practice as anaesthesia care providers. OBJECTIVES: To assess the anaesthesia nursing competence of nursing students and to describe factors related to their anaesthesia nursing competence. This study will provide new knowledge to support the curricula of nursing education and new nurses' practice in anaesthesia care. DESIGN: Cross-sectional survey design. METHODS: Data from a sample of Finnish nursing students (n = 205) were collected by using an on-line/paper and pencil survey (the Anaesthesia Nursing Competence Scale, 7 categories) in 2017. The assessment was based on self-assessment and used a Visual Analogue Scale (0-100). Descriptive statistics, a Pearson correlation coefficient, independent sample t-tests and a multivariable regression were used to analyse the data. RESULTS: The self-assessed overall competence of graduating nursing students was 59 (range 43-73). Approximately half of the students reached an acceptable level (60≤) and half did not. The highest self-assessed category was collaboration within patient care, and the lowest was knowledge of anaesthesia patient care. The number of credits, anaesthesia courses, and experience of clinical practice in anaesthesia nursing were significantly related to anaesthesia nursing competence. CONCLUSIONS: Competence development in the knowledge of anaesthesia patient care should be considered in general nursing education. Student nurses' competence could be developed by providing more opportunities for theoretical studies and clinical practice in anaesthesia nursing. A specialised post-registration education in anaesthesia nursing might be one solution to overcome the limitations in the competence that general nursing education is not fully able to cover for anaesthesia nursing.

Effectiveness of complementary and alternative medicine interventions for sleep quality in adult intensive care patients: A systematic review.

BACKGROUND: Pharmacological interventions for sleep (analgesic, sedative and hypnotic agents) can both disrupt and induce sleep and have many negative side effects within the intensive care population. The use of complementary and alternative medicine therapies to assist with sleep has been studied but given the variety of modalities and methodological limitations no reliable conclusions have been drawn. OBJECTIVE: To synthesise research findings regarding the effectiveness of using complementary and alternative medicine interventions within the domains of mind and body practices (relaxation techniques, acupuncture) and natural biologically based products (herbs, vitamins, minerals, probiotics) on sleep quality and quantity in adult intensive care patients. REVIEW METHOD USED: Systematic review. DATA SOURCES: Five databases were searched in August 2018 and updated in February 2019 and 2020. REVIEW METHODS: Searches were limited to peer reviewed randomised controlled trials, published in English involving adult populations in intensive care units. Interventions were related to the complementary and alternative medicine domains of mind and body practices and natural products. Included studies were assessed using Cochrane's risk of bias tool. RESULTS: Seventeen studies were included. The interventions used varied: 4 investigated melatonin; 4 music +/- another therapy; 3 acupressure; 2 aromatherapy and 1 each for relaxation and imagery, reflexology, bright light exposure and inspiratory muscle training. Measurement of sleep quantity and quality was also varied: 5 studies used objective measures such as Polysomnography and Bispectral index with the remaining using subjective patient or clinician assessment (for example, Richards-Campbell Sleep Questionnaire, Pittsburgh Sleep Quality Index, observation). Given the different interventions, outcomes and measures used in the studies a meta-analysis was not possible. Generally, the results support the use of complementary and alternative medicine for assisting with sleep with 11 out of 17 trials reporting significant results for the interventions examined. CONCLUSIONS: Complementary and alternative medicine interventions, in particular, melatonin and music, have shown promise for improving sleep in adults with critical conditions; however, further research that addresses the limitations of small sample sizes and improved techniques for measuring sleep is needed.

Sleep in the intensive care unit - nurses' documentation and patients' perspectives.

BACKGROUND: Inability to sleep is one of the most distressing factors for patients in the intensive care unit (ICU). Sleep is perceived as light and awakenings are numerous. Nurses' documentations of sleep are narrow, mainly concentrating on the quantity and general quality. Nurses should diversely evaluate, document and promote sleep to provide patient centered care. AIM: To investigate the content of nurses' documentation about the sleep of ICU patients, patients' own perceptions of sleep, and the correspondence of the two. DESIGN AND METHODS: Nurses' documentations (n = 90) were analysed retrospectively with quantitative content analysis. A cross-sectional survey of patients' (n = 114) perspectives was collected with the five-item Richards-Campbell Sleep Questionnaire (RCSQ), on a visual analogue scale from 0 (the poorest quality sleep) to 100 (optimum sleep). The data was analysed statistically. Correspondence was tested with cross-tabulation. RESULTS: Nurses documented sleep quantity for 71% and quality for 27% of patients, along with the needs assessment, used interventions and their effect on sleep. Patients' perspectives varied widely. Sleep depth was rated the lowest and falling asleep highest of the RCSQ sleep domains. Age of the patients correlated positively with general quality of sleep, sleep depth and falling asleep. Nurses' documentations and patients' perceptions correlated in over half of the cases. CONCLUSIONS: Nurses' documentation of ICU patients' sleep is not systematic or comprehensive and corresponds only partially with patients' own perception. The sleep of non-intubated patients is light and awakenings are frequent. Documentation of ICU patients' sleep should include the whole nursing process, i.e. needs assessment, interventions used, and evaluation of sleep and the effects of the interventions, along with patients' own perspective to promote patient-centered care. RELEVANCE TO CLINICAL PRACTICE: Evaluation and documentation of patients' sleep must include patients' own perception to be comprehensive. Nurses' documentation should include all elements of nursing process.

Evaluation of patients' sleep by nurses in an ICU.

AIMS AND OBJECTIVES: To determine how intensive care unit evaluations of patients' sleep by nurses correspond to polysomnography and if changes in patients' physiologic parameters could be helpful in sleep evaluation. BACKGROUND: The evaluations of patients' sleep by nurses have not corresponded very well with objective sleep recordings, so there is a need for further knowledge in this field. DESIGN: Correlational study of patients' sleep, nurses' sleep evaluations and the sleep-related heart rate and blood pressure changes. METHODS: The standard overnight polysomnography was recorded on 21 patients. Simultaneously, nurses marked into an electronic patient care documentation system all the changes noted in the patients' sleep status. Patients' arterial blood pressure and heart-rate data were automatically saved into the electronic patient care documentation. RESULTS: The evaluations of patients' sleep/wake state by nurses corresponded to polysomnography 68% of the time. A correlation was found between nurses' evaluations and polysomnography recordings only on total sleep time. There was no correlation in the other sleep aspects (sleep latency, amount of awakenings or movements during sleep). Most patients' blood pressures and heart rate varied according to sleep/wake state. There was less variation if the patient had received noradrenalin for blood pressure control. CONCLUSION: The evaluations of patients' sleep/wake state by nurses only correspond to the polysomnography two-thirds of the time. Thus, more sophisticated evaluation methods should be developed to aid nurses in sleep evaluations. Sleep-related changes in blood pressure and heart rate can be seen in intensive care unit patients, so using these parameters as part of the patients' sleep evaluation should be further explored. RELEVANCE TO CLINICAL PRACTICE: The nurses' evaluation practices of intensive care unit patients' sleep need further development. Monitoring the changes in patients' heart rate and blood pressure may aid in evaluating his/her sleep.

Basic Competence of Intensive Care Unit Nurses: Cross-Sectional Survey Study.

Critical care patients benefit from the attention of nursing personnel with a high competence level. The aim of the study was to describe and evaluate the self-assessed basic competence of intensive care unit nurses and related factors. A cross-sectional survey design was used. A basic competence scale (Intensive and Critical Care Nursing Competence Scale version 1, Likert scale 1-5, 1 = poor and 5 = excellent) was employed among Finnish intensive care unit nurses (n = 431). Intensive care unit nurses' self-assessed basic competence was good (mean 4.19, SD 0.40). The attitude and value base of basic competence was excellent whereas experience base was the poorest compared to the knowledge base and skill base of intensive and critical care nursing. The strongest factor explaining nurses' basic competence was their experience of autonomy in nursing care (F value 60.85, ß 0.11, SE 0.01, and P ≤ 0.0001). Clinical competence was self-rated as good. Nurses gave their highest competence self-ratings for ICU patient care according to the principles of nursing care. The ICU nurses also self-rated their professional competence as good. Collaboration was self-rated as the best competence. In basic and continuing education and professional self-development discussions it is meaningful to consider and find solutions for how to improve nurses' experienced autonomy in nursing.

Sleep and nursing care activities in an intensive care unit.

This study aimed to describe the quality of sleep of non-intubated patients and the night-time nursing care activities in an intensive care unit. The study also aimed to evaluate the effect of nursing care activities on the quality of sleep. An overnight polysomnography was performed in 21 alert, non-intubated, non-sedated adult patients, and all nursing care activities that involved touching the patient were documented by the bedside nurse. The median (interquartile range) amount of sleep was 387 (170, 486) minutes. The portion of deep non-rapid-eye-movement (non-REM) sleep varied from 0% to 42% and REM sleep from 0% to 65%. The frequency of arousals and awakenings varied from two to 73 per hour. The median amount of nursing care activities was 0.6/h. Every tenth activity presumably awakened the patient. Patients who had more care activities had more light N1 sleep, less light N2 sleep, and less deep sleep. Nursing care was often performed while patients were awake. However, only 31% of the intervals between nursing care activities were over 90 min. More attention should be paid to better clustering of care activities.

Evaluating adult patients' sleep: an integrative literature review in critical care.

BACKGROUND: Patients in a critical care unit sleep quite poorly even when they appear to be sleeping. Sleep is light and fragmented. Acute lack of sleep causes patients suffering in the form of fatigue, irritability, disorientation and hallucinations. It may also affect their recovery and immune defence. To promote sleep, nurses must be able to evaluate patients' sleep reliably. AIM AND OBJECTIVES: Our aim was to form a comprehensive overview of the sleep evaluation methods in critical care. Our objectives were to determine the content and the quality of the methods as reported by the researchers. This overview hopefully improves the use of the sleep evaluation methods as part of sleep promoting nursing interventions and practices. METHOD: The literature search was performed from the Ovid MEDLINE, CINAHL, an 'All EBM Reviews', and PsycINFO databases. The search terms sleep, evaluating sleep and critical care were used. An integrative review method was used to analyse the data. RESULTS: According to the 52 articles of this review, there is a wide variety of methods to evaluate patients' sleep in critical care by observation, by asking for patient's own perception and by objective measures. Most instruments evaluate only total sleep time or the quality of sleep in general. The validity and reliability of the instruments has been insufficiently reported. Some questionnaires for patients' perception have been tested and used in several studies. CONCLUSION: Sleep evaluation instruments do not cover all dimensions of sleep since they mostly measure total sleep time or estimate the overall quality of sleep. The quality of the sleep evaluation instruments varies from scientifically tested tools to untested instruments. This review will allow nurses to recognise the strengths and limitations of sleep evaluation instruments when selecting one to be used in critical care. Valid information about patients' sleep enables nurses to facilitate it.

Basic competence in intensive and critical care nursing: development and psychometric testing of a competence scale.

AIMS AND OBJECTIVES: To develop a scale to assess basic competence in intensive and critical care nursing. In this study, basic competence denotes preliminary competence to practice in an intensive care unit. BACKGROUND: There is a need for competence assessment scales in intensive care nursing practice and education. The nursing care performed in the intensive care unit is special by its nature and needs to be assessed as such. At this moment, however, there is no tested, reliable and valid scale in this field. DESIGN: A multi-phase, multi-method development and psychometric testing of the scale was conducted. METHODS: The scale was developed in three phases. First, following a literature review and Delphi study, the items were created. Second, the scale was pilot tested twice by nursing students (n1 = 18, n2 = 56) and intensive care nurses (n1 = 12, n2 = 54), and revisions were made. Third, reliability and construct validity were tested by graduating nursing students (n = 139) and intensive care nurses (n = 431). RESULTS: The Intensive and Critical Care Nursing Competence Scale (ICCN-CS-1) is a self-assessment test consisting of 144 items. Basic competence is divided into patient-related clinical competence and general professional competence. In addition, basic competence is comprised of knowledge base, skill base, attitude and value base and experience base. ICCN-CS-1 is a reliable and tolerably valid scale. CONCLUSIONS: The ICCN-CS-1 is a promising scale for use among nursing students and nurses. Future research is needed to evaluate its construct validity further and to assess its suitability for completion during intensive care unit's orientation programmes and nursing students' clinical practice in an intensive care unit. RELEVANCE TO CLINICAL PRACTICE: The ICCN-CS-1 can be used for basic competence assessment in professional development discussions in intensive care units, in mentor evaluation situations during nursing students' clinical practice and in intensive care nursing education.

Graduating nursing students' basic competence in intensive and critical care nursing.

AIMS AND OBJECTIVES: To describe and evaluate the basic competence of graduating nursing students in intensive and critical care nursing. BACKGROUND: Intensive and critical care nursing is focused on severely ill patients who benefit from the attention of skilled personnel. More intensive and critical care nurses are needed in Europe. Critical care nursing education is generally postqualification education that builds upon initial generalist nursing education. However, in Europe, new graduates practise in intensive care units. Empirical research on nursing students' competence in intensive and critical care nursing is scarce. DESIGN: A cross-sectional survey design. METHODS: A basic competence scale (Intensive and Critical Care Nursing Competence Scale, version 1) and a knowledge test (Basic Knowledge Assessment Tool, version 7) were employed among graduating nursing students (n = 139). RESULTS: Sixty-nine per cent of the students self-rated their basic competence as good. No association between self-assessed Intensive and Critical Care Nursing-1 and the results of the Basic Knowledge Assessment Tool-7 was found. The strongest factor explaining the students' conception of their competence was their experience of autonomy in nursing after graduation. CONCLUSION: The students seem to trust their basic competence as they approach graduation. However, a knowledge test or other objective method of evaluation should be used together with a competence scale based on self-evaluation. RELEVANCE TO CLINICAL PRACTICE: In nursing education and in clinical practice, for example, during orientation programmes, it is important not only to teach broad basic skills and knowledge of intensive and critical care nursing, but also to develop self-evaluation skills through the use of special instruments constructed for this purpose.

Biological and physiological knowledge and skills of graduating Finnish nursing students to practice in intensive care.

This study describes the basic biological and physiological knowledge and skills of graduating nurse students in Finland against the requirement of their being able to practice safely and effectively in intensive care. The study describes also their interest and willingness to work in intensive care. Measurements were based on the Basic Knowledge Assessment Tool (BKAT-5) developed by Toth in the United States. The sample consisted of 130 nursing students graduating in December 2001 and January 2002. The data were analysed statistically. The students were most knowledgeable in the areas of appropriate precautions, living will and medical calculation, followed by neurology and endocrinology. Scores were poorest for pulmonary, gastrointestinal and cardiovascular knowledge. Intensive care studies and the desire to work in intensive care correlated significantly with the respondents' basic intensive care knowledge. It is important for nursing education to concentrate on developing those areas of intensive care studies where the performance of students is weakest.
