Aim: Nursing care activities conducted at night tend to disturb their sleep, but to our knowledge, no nocturnal care protocols for pressure injury prevention have been established. This scoping review aimed to map the nocturnal care for pressure injury prevention and propose nocturnal care recommendations that have a reduced impact on the patient's care environment., Methods: Literature databases were searched and two independent researchers screened the articles according to the inclusion criteria and extracted the data. The inclusion criteria were original articles/case studies, studies involving human subjects, and studies on nocturnal care for the prevention of pressure injuries., Results: Eight met the inclusion criteria, three studies focused on bedding and five on care activities. Parasympathetic activity was more likely to be maintained or enhanced when an automatic repositioning function was used. Additionally, the time to sleep resumption was significantly shorter when repositioning was performed during deep sleep than during shallow sleep. Significantly fewer awakenings in response to light or sound occurred when incontinence care was provided to awake patients than when it was performed regularly. Moreover, some studies have highlighted the usefulness of the small change method and the 30° side-lying position for repositioning., Conclusion: Using a mattress with an automated turning function, providing care during wakefulness or deep sleep, and using repositioning methods with small positional changes may be effective in reducing the impact on patient's care environment. Further research is needed to determine nocturnal care for pressure injury prevention with less impact on the patient's care environment., Competing Interests: Declaration of competing interest The authors report no conflicts of interest in this work., (Copyright © 2024.

The purpose of this study was to analyze the influence of the mothers' nighttime responses on the sleep-wake rhythm of their 1-month-old infants. This study used an anonymous self-administered survey questionnaire with 1133 mothers of 1-month-old infants. The questionnaire investigated basic information about the parents, growth environment of infants, mothers' sleep patterns during pregnancy, and infants' sleep patterns at the age of one month. Logistic regression analysis was used to analyze the influence of nighttime responses on the risk of infants sleeping longer during the day than at night. Regarding nighttime response behavior, it was found that immediately picking up 1-month-old infants results in longer sleep during the day than at night (OR 1.616 [1.017 - 2.566], p = 0.042), compared to delaying picking up the infant. It was suggested that the stimulation due to picking up an infant may affect sleep-wake rhythm formation., (© 2021. The Author(s).)

Aims: To synthesize research on the influence of night-shift napping on nurses., Background: Shift work is common for hospital nurses. Various studies corroborate that shift work causes adverse health consequences for nurses. Night-shift napping is a countermeasure to address the adverse outcomes of shift work., Design: A mixed-methods systematic review., Data Sources: The literature search included the PubMed, Web of Science, Embase, PsycINFO and Cochrane Library electronic databases from inception to December 2017. Reference lists were hand searched. Only English articles were chosen., Review Methods: A sequential explanatory design and Cochrane's methods for integrating qualitative and implementation evidence in intervention effectiveness reviews. The Mixed Methods Assessment Tool and Cochrane Risk of Bias Tool were applied to assess the methodological quality of included studies., Results: Twenty-two studies met our inclusion criteria. Many nurses experienced napping during their night-shift although no clear policy emerged. Napping is beneficial to the well-being of nurses and could improve their psychomotor vigilance and performance. However, the related studies are limited. The evidence on reducing sleepiness and fatigue was also insufficient and napping in nursing still faces challenges., Conclusion: Although research on this topic has just started, napping during night-shift is beneficial to nurses' health and performance. Research should further explore the long-term impact on of night-shift napping on nurses, people and organization using sound methodological designs. Managers should actively develop strategies to address night-shift napping barriers., (© 2018 John Wiley & Sons Ltd.)

There is much debate between neonatologists and paediatricians about appropriate oxygen saturation targets for babies with chronic neonatal lung disease (CNLD). Overnight oximetry is used to guide the fraction of inspired oxygen to use. We did this literature review to examine the current literature on the use of overnight oximetry in term infants, preterm infants and babies with CNLD (especially relevant to ex-preterm babies with CNLD going home on oxygen). We reviewed the literature from January 1990 to October 2017 by searching the following databases: Cochrane Central Register of Controlled Trials, The Joanna Briggs Institute, CINAHL, MEDLINE, Scopus, EMBASE, ProQuest and Science Direct. Sixteen articles were included in the review. The literature available on overnight oximetry in neonates is limited, it is not contemporary, and it reports studies that did not use oximeters with modern software for data collection and analysis. It is imperative that reference ranges be defined for overnight oximetry parameters so that babies are not inadvertently administered inappropriate amounts of oxygen., (© 2018 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).)

Rationale: Dexmedetomidine is associated with less delirium than benzodiazepines and better sleep architecture than either benzodiazepines or propofol; its effect on delirium and sleep when administered at night to patients requiring sedation remains unclear., Objectives: To determine if nocturnal dexmedetomidine prevents delirium and improves sleep in critically ill adults., Methods: This two-center, double-blind, placebo-controlled trial randomized 100 delirium-free critically ill adults receiving sedatives to receive nocturnal (9:30 p.m. to 6:15 a.m.) intravenous dexmedetomidine (0.2 μg/kg/h, titrated by 0.1 μg /kg/h every 15 min until a goal Richmond Agitation and Sedation Scale score of -1 or maximum rate of 0.7 μg/kg/h was reached) or placebo until ICU discharge. During study infusions, all sedatives were halved; opioids were unchanged. Delirium was assessed using the Intensive Care Delirium Screening Checklist every 12 hours throughout the ICU admission. Sleep was evaluated each morning by the Leeds Sleep Evaluation Questionnaire., Measurements and Main Results: Nocturnal dexmedetomidine (vs. placebo) was associated with a greater proportion of patients who remained delirium-free during the ICU stay (dexmedetomidine [40 (80%) of 50 patients] vs. placebo [27 (54%) of 50 patients]; relative risk, 0.44; 95% confidence interval, 0.23-0.82; P = 0.006). The average Leeds Sleep Evaluation Questionnaire score was similar (mean difference, 0.02; 95% confidence interval, 0.42-1.92) between the 34 dexmedetomidine (average seven assessments per patient) and 30 placebo (six per patient) group patients able to provide one or more assessments. Incidence of hypotension, bradycardia, or both did not differ significantly between groups., Conclusions: Nocturnal administration of low-dose dexmedetomidine in critically ill adults reduces the incidence of delirium during the ICU stay; patient-reported sleep quality appears unchanged.

Aims and Objectives: To explore the context and the influence of night-time care routine interactions (NCRIs) on night-time sleep effectiveness (NSE) and daytime sleepiness (DSS) of patients in the cardiac surgery critical-care and progressive-care units of a hospital., Background: There exists a paucity of empirical data regarding the influence of NCRIs on sleep and associated outcomes in hospitalised adult cardiac surgery patients., Methods: An exploratory repeated-measures research design was employed on the data provided by 38 elective cardiac surgery patients (mean age 60.0 ± 15.9 years). NCRI forms were completed by the bedside nurses and patients completed a 9-item Visual Analogue Sleep Scale (100-mm horizontal lines measuring NSE and DSS variables). All data were collected during postoperative nights/days (PON/POD) 1 through 5 and analysed with IBM SPSS software., Results: Patient assessment, medication administration and laboratory/diagnostic procedures were the top three NCRIs reported between midnight and 6:00 a.m. During PON/POD 1 through 5, the respective mean NSE and DSS scores ranged from 52.9 ± 17.2 to 57.8 ± 13.5 and from 27.0 ± 22.6 to 45.6 ± 16.5. Repeated-measures ANOVA showed significant changes in DSS scores (p < .05). NSE and DSS were negatively correlated (r = -.44, p < .05), but changes in NSE scores were not significant (p > .05). Finally, of 8 NCRIs, only 1 (postoperative exercises) was significantly related to sleep variables (r > .40, p < .05)., Conclusion and Relevance to Clinical Practice: Frequent NCRIs are a common occurrence in cardiac surgery units of a hospital. Further research is needed to make a definitive conclusion about the impact of NCRIs on sleep/sleep disruptions and daytime sleepiness in adult cardiac surgery. Worldwide, acute and critical-care nurses are well positioned to lead initiatives aimed at improving sleep and clinical outcomes in cardiac surgery., (© 2018 John Wiley & Sons Ltd.)

Background: Rapid Response Teams (RRTs) are groups of healthcare providers that are used by many hospitals to respond to acutely deteriorating patients admitted to the wards. We sought to identify outcomes of patients assessed by RRTs outside standard working hours., Methods: We used a prospectively collected registry from two hospitals within a single tertiary care-level hospital system between May 1, 2012, and May 31, 2016. Patient information, outcomes, and RRT activation information were stored in the hospital data warehouse. Comparisons were made between RRT activation during daytime hours (0800-1659) and nighttime hours (1700-0759). The primary outcome was in-hospital mortality, analyzed using a multivariable logistic regression model., Results: A total of 6023 RRT activations on discrete patients were analyzed, 3367 (55.9%) of which occurred during nighttime hours. Nighttime RRT activation was associated with increased odds of mortality, as compared with daytime RRT activation (adjusted OR 1.34, 95% CI 1.26-1.40, P = 0.02). The time periods associated with the highest odds of mortality were 0600-0700 (adjusted OR 1.30, 95% CI 1.09-1.61) and 2300-2400 (adjusted OR 1.34, 95% CI 1.01-1.56). Daytime RRT activation was associated with increased odds of intensive care unit admission (adjusted OR 1.40, 95% CI 1.31-1.50, P = 0.02). Time from onset of concerning symptoms to RRT activation was shorter among patients assessed during daytime hours (P < 0.001)., Conclusions: Acutely deteriorating ward patients assessed by an RRT at nighttime had a higher risk of in-hospital mortality. This work identifies important shortcomings in health service provision and quality of care outside daytime hours, highlighting an opportunity for quality improvement.

This project describes a multifaceted noise reduction program on 2 hospital units designed to ensure a quiet hospital environment, with the goal of improving the patient experience. The noise committee in an urban city hospital developed a plan to control noise including scripted leadership rounding, staff education, a nighttime sleep promotion cart, and visual aids to remind staff to be quiet. Postintervention improvement in patient satisfaction scores was noted.

Objectives: To study quality of patient rest before and after an intervention to reduce nighttime light and noise in the emergency department observation area of an urban hospital., Material and Methods: Quasi-experimental study in 2 groups before and after the intervention in the observation area of the Hospital Clínic de Barcelona. We administered a questionnaire about the quality of nighttime rest to assess the effect of light and noise on sleep. Light and noise were reduced by means of structural changes to the environment and through the introduction of protocols to modify how care plans were carried out at night., Results: Fifty nurses participated in the pre-intervention study and 371 in the post-intervention study. Seventy-two percent and 91.37% of the patients reported resting well before and after the intervention, respectively (P< .001). Factors like pain, nursing care, or daytime naps do not affect sleep quality., Conclusion: Nighttime rest in emergency department observation areas is affected by ambient light and noise more than by other variables. Reducing light and noise at night can measurably improve patients' rest.

Nighttime restlessness in dementia is an underestimated problem. Although little is known about the prevalence and not every person with dementia struggles with it, nighttime restlessness puts a heavy burden on the persons themselves and their caregivers.This field study explores nighttime restlessness in nursing homes based on two research questions: (1) What is nighttime restlessness according to professional caregivers? and (2) How is nighttime restlessness managed?Data were collected through diaries, interviews with caregivers and one night of observation in eight nursing homes.Wandering and screaming seem to be the most prevalent nighttime agitated behaviours. Caregivers identify many possible causes, but spatial and sensory factors, such as light or noise, were rarely mentioned spontaneously. The observations highlighted that a lot of light and noise is prominent and this might be causing nighttime restlessness.Caregivers try several strategies: for example talking with the resident, put on a light and apply medication or physical restraints.The management of nighttime restlessness requires a holistic approach. Caregivers' attention for and efforts to ameliorate the spatial and sensory environment in the management of nighttime restlessness are limited.

Background: Sleep disturbance in an intensive care unit is a common problem. One of the main factors causing sleep disturbances in an intensive care unit is nocturnal patient care interventions., Aims and Objectives: This study aims to determine the impact of patient care interventions performed at night in a neurosurgical intensive care unit on patients' sleep and their nursing care satisfaction., Methods: The descriptive study was conducted on 82 patients in a neurosurgical intensive care unit between January 2009 and March 2010. The data were collected by data collection instruments and Newcastle Satisfaction with Nursing Scales. The data were statistically analyzed by frequency, mean, standard deviation, chi-square, and Mann-Whitney U test., Results: The study showed that 53.7% of the patients experienced sleep disturbances in the neurosurgical intensive care unit. Because of nursing interventions at night, 39.1% of these patients had their sleep affected, but this problem did not cause any negative impact on the patients' satisfaction (Newcastle Satisfaction with Nursing Scales score = 88.21 ± 9.83). The patients received, on average, 42.21 ± 7.45 times patient care interventions at night; however, the frequency of patient care interventions at night showed no effect on sleep disturbances in this study (p > .05). The most frequently given patient care interventions were, respectively, vital signs monitoring, neurological assessment, and repositioning in bed. These interventions were performed commonly at 6 a.m., 12 a.m., and 7 p.m., Conclusion: In this study, despite the patients reporting sleep disturbances in the neurosurgical intensive care unit because of nocturnal patient care interventions that prevented them from sleeping, the patients' satisfaction on the given nursing care was not negatively impacted. To reduce sleep disturbances because of nursing care initiatives and promote uninterrupted sleep in the intensive care unit, it can be useful to develop new protocols regulating night care activities.

Purpose: To investigate the role of nighttime vital sign assessment in predicting acute care transfers (ACT) from inpatient rehabilitation., Design: Retrospective chart review., Methods: Fifty patients unexpectedly discharged to acute care underwent chart review to determine details of each ACT., Findings: Seven of 50 ACT possessed new vital sign abnormalities at the 11 pm vital sign assessment the night before ACT. None of these seven underwent ACT during the night shift the abnormalities were detected. Two of 50 ACT were transferred between 11 pm and 6:59 am; both demonstrating normal vital sign at the 11 pm assessment. During study period, an estimated 5,607 11 pm vital sign assessments were performed., Conclusions: Nighttime vital sign assessments do not seem to be a good screening tool for clinical instability in the rehabilitation hospital., Clinical Relevance: Eliminating sleep disturbance is important to the rehabilitation inpatient as inadequate sleep hinders physical performance. Tailoring vital sign monitoring to fit patents' clinical presentation may benefit this population., (© 2014 Association of Rehabilitation Nurses.)

Background: The Stroke Oxygen Study (SO₂S) is a multi-center randomized controlled trial of oxygen supplementation in patients with acute stroke. The main hypothesis for the trial is that fixed-dose oxygen treatment during the first 3 days after an acute stroke improves outcome. The secondary hypothesis is that restricting oxygen supplementation to night time only is more effective than continuous supplementation. This paper describes the statistical analysis plan for the study., Methods and Design: Patients (n = 8000) are randomized to three groups: (1) continuous oxygen supplementation for 72 hours; (2) nocturnal oxygen supplementation for three nights; and (3) no routine oxygen supplementation. Outcomes are recorded at 7 days, 90 days, 6 months, and 12 months. The primary outcome measure is the modified Rankin scale at 90 days. Data will be analyzed according to the intention-to-treat principle. Methods of statistical analysis are described, including the handling of missing data, the covariates used in adjusted analyses, planned subgroups analyses, and planned sensitivity analyses., Trial Registration: This trial is registered with the ISRCTN register, number ISRCTN52416964 (30 September 2005).

Introduction: Robotic tele-presence (RTP) is a form of mobile telemedicine, which enables a direct face-to-face rapid response by the physician, instead of the traditional telephonic paradigm. We hypothesized that a model of RTP for after-hour ICU rounds and emergencies would be associated with improved ICU nurse satisfaction., Methods: We implemented a prospective nighttime multidisciplinary ICU round time, using RTP at our neuro-ICU. To test for critical ICU nurse team satisfaction, a questionnaire was implemented. The primary outcome was nurse satisfaction measured through a questionnaire with answers trichotomized into: agreement, disagreement, and no opinion. The occurrence of outcomes was compared between the groups by χ2 or Fisher exact tests for the difference in proportions (PD) with Bonferroni correction for multiple pairwise comparisons., Results: In total, 34 nurses completed the pre-survey and 40 nurses completed the post-survey. Night nurses were more likely to agree that RTP was associated with: ICU physicians being sufficiently available in the ICU (agreement 6-20%, PD 14%, p = 0.008), present during acute emergencies (agreement 44-65%, PD 21%, p = 0.007), and had enough time to get questions answered from the physician team (agreement 41-53%, PD 11%, p = NS)., Conclusions: This data suggest improvement in critical care nursing team satisfaction with a model of RTP in the neuroscience ICU, particularly during nighttime hours. RTP is a tool that may enhance communication among components of the ICU team.

This article presents the key findings from an extensive research project aiming to identify the determinants of poor sleep in care homes. A mixed methods study was conducted in 10 care homes in South East England. This included 2-week daily diaries completed by 145 older residents and interviews with 50 care-home staff. This research demonstrated that the regular surveillance by qualified nurses and care assistants at night seriously impedes the quality of sleep experienced by older people living in care homes. However, nurses and social care workers have a duty of care, which would not be fulfilled if regular checks were not undertaken at night. There is a need for care-home staff to strike a balance between enabling older people living in care homes to have a good night's sleep and adhering to their own professional duty of care.

Background: Pharmacological and non-pharmacological approaches are commonly used to treat patients' institutionalised for nighttime wandering. Actigraphy and other scales have been used to evaluate the efficacy of these treatments. However, in clinical settings, nursing records are often the sole source of daily observation of nighttime wandering. Thus, physicians rely on nursing records to evaluate pharmacological and non-pharmacological treatments. This study examined nighttime movements of patients with dementia, comparing the results of integrated circuit tag monitoring with hourly nighttime nursing records. We tested which factors were associated with agreement rates between the two data sources., Methods: The study hospital was a general hospital in Osaka, Japan. Monitoring was conducted in a closed 60-bed dementia care unit. An integrated circuit tag monitoring system was used to monitor the movement of institutionalised dementia patients for over half a year. The distance moved per hour by subjects was measured using the monitoring system, and the data were compared with hourly nighttime nursing records. Agreement rates were calculated between the two data sources., Results: Thirty-five patients were monitored. Between 10-30% of subjects moved at any given hour during the night. The overall agreement rate between sources of movement data was 39%. Agreement rates were significantly correlated with the interquartile of the distance moved, changes in medication, physical conditions, and behavioural and psychological symptoms of dementia measured during the day., Conclusions: Although the agreement rate was low, staff appeared to pay more attention to patients associated with notable events during the day and patients exhibiting variability in distance moved., (© 2011 The Authors.

Sleep-disordered breathing may take the form of apnoea or hypopnoea. These conditions have physiological consequences on the cardiovascular function. Night staff in cardiac rehabilitation departments must therefore be able to organise themselves to screen for risks of sleep-disordered breathing, with collaboration between medical and paramedical staff.

Patients' perceptions of noise events that prevent/interrupt nighttime sleep after cardiac surgery and sleep promotion aids were studied for associations with patient characteristics. Overhead paging, equipment, and loud communication prevented/interrupted nighttime sleep; however, most patient characteristics were not associated with the presence or absence of these noise events. Patients selected pain medication to promote sleep. Other sleep aids were used infrequently. Behavioral and structural noise reduction interventions are needed to minimize sleep interruptions.

Hospitalized elders frequently experience disturbed sleep related to environmental factors. To determine relationships between sleep and environmental noise and light, a descriptive exploratory study was conducted with 48 hospitalized older adults. Participants aged 70 years or older were monitored for sleep via wrist actigraphy, and noise and light levels were measured the first night of hospitalization. Sleep time was brief (mean, 3.75 hours) and fragmented (mean, 13 awakenings per night). The sleep environment was noisy with a median sound level of 49.65 dB(A). There was an average of 3 periods of elevated light levels (mean, 64 lux) lasting an average of 1.75 hours each night. No significant correlation was found among sleep and age, light, and sound. Recommendations include light and sound reduction measures and dedicated "do not disturb" times to allow for a full 90-minute sleep cycle., (Copyright 2010 Mosby, Inc. All rights reserved.)

Background: Hospital routines frequently interrupt nighttime sleep. Sedatives promote sleep, but increase the risk of delirium and falls. Few interventional trials have studied sleep promotion in medical-surgical units and little is known about its impact on sedative use., Objective: To determine causes of sleep disruption, and assess whether decreasing sleep disruptions lowers sedative use in medical-surgical patients., Design and Setting: Interventional trial with historical controls on a medical-surgical unit of a community teaching hospital. Nurses, physicians, and patients were blinded to the measurement of as-needed sedative use., Patients: Consecutive eligible adults (n = 161 preintervention patients, n = 106 intervention patients)., Intervention: We developed the "Somerville Protocol," which included the establishment of an 8-hour "Quiet Time" that began with automated lights-off and lullaby; staff-monitored noise; and avoidance of waking of patients for routine vital signs and medications., Measurements: As-needed sedative use, responses to a patient questionnaire, and responses to a modified Verran Snyder-Halpern (VSH) sleep scale., Results: Preintervention, "hospital staff " was the disturbance most likely to keep patients awake. The intervention decreased the proportion of patients reporting it from 42% to 26%, a 38% reduction (P = 0.009; 95% confidence interval [CI]: 0.0452-0.2765). Preintervention, 32% of patients received as-needed sedatives, compared to 16% with the intervention, a 49% reduction (P = 0.0041; 95% CI: 0.056-0.26), with a 62% decrease in patients over age 64 years (P = 0.005). VSH scores were unchanged., Conclusions: Small modifications in hospital routines, especially in the timing of vital signs and routine medication administration, can significantly reduce sedative use in unselected hospital patients.

Aim: The aim of this study is to provide objective evidence that clear visual input and change in standing sequence can reduce fall risk related to night toilet use among hospitalized older patients., Background: In hospitalized older patients, falls are likely to occur during night toileting needs., Method: Using a stabilometer, we measured and compared maximal standing sway for 10 seconds immediately after standing with three visual input modes in two standing patterns, comparing healthy younger adults (n=22) and older patients (n=19). The three modes are no visual input (mode 1), vague (mode 2), and clear visual input (mode 3). Standing sequences A and B are defined as supine-to-standing and supine-to-sitting-to-standing, respectively., Results: For a given visual mode, maximal moved distance was significantly greater for older patients than for younger adults with both standing patterns (P<0.0001). Both standing pattern B and clear visual input decreased maximal moved distance in younger adults and older patients. A greater maximal moved distance score indicated a greater fall risk., Relevance to Clinical Practice: It is important for nurses to train older patients to turn on the light and perform standing pattern B, when going to the bathroom at night. In addition, it is advisable to confirm the placement of distinct visual markers on the way to the bathroom., (© 2009 Blackwell Publishing Ltd.)

Assistive Technology (AT) has been utilized to support people with dementia (PwD) and their carers in the home. Such support can extend the time that PwD can remain safely at home and reduce the burden on the tertiary healthcare sector. Technology can assist people in the hours of darkness as well as during the day. The objective of this literature review is to evaluate reported healthcare technologies appropriate to night time care. This paper summarises and categorises the current evidence base. In all, 131 abstracts were returned from a database search, yielding fifty four relevant papers which were considered in detail. While night-time specific studies identified very few papers (4 papers, 7%), most of the more general AT findings could be adopted to benefit night-time assistance. Studies have used technology for prompting and reminding as loss of time and forgetfulness are major problems; for monitoring daily activities in a sensor enriched environment and utilised location aware technologies to provide information to enhance safety. Technology also supports a range of therapies to alleviate symptoms. Therapies include the delivery of music and familial pictures for reminiscing, the use of light therapy to enhance wellbeing and the provision of mental tasks to stimulate the brain and maintain activity levels.

This article reports the qualitative arm of a mixed-methods study designed to test an in-home nighttime monitoring system (NMS) that tracks the nighttime activity of persons with dementia. Fourteen caregiver interviews were analyzed using grounded theory/full conceptual description methods to determine the issues associated with providing care at night and to explore the benefits of using the NMS. Caregivers not using the NMS experienced sleep disruption, overwhelming worry, and loss of personal space, leading to decreased energy and changes in mood. When the NMS was used, caregivers reported improved "peace of mind." The fear and uncertainty associated with worry was alleviated by reliable alerts regarding the whereabouts of the person with dementia. Some caregivers were able to better balance needs for personal space with needs to remain in contact with the person with dementia. Generally, caregivers reported improved quality of sleep, although some caregivers reported more awakenings due to the system alerts., (Copyright 2009, SLACK Incorporated.)

Aim: This paper is a report of a study to examine what opportunities night nurses have to learn in terms of being able to distinguish variations in the patients' conditions., Background: Night nurses often lack access to the formalized in-service training offered to day nurses. As every clinical experience can be seen as an opportunity for learning, learning takes place even at night. However, the learning of night nurses has not been studied previously., Method: This study is based on interviews with a convenience sample of 10 night nurses at a medium-sized Swedish hospital in 2001. These interviews were reanalysed in 2006 concerning learning situations. The interviews were tape-recorded, transcribed verbatim, coded and examined using latent content analysis., Findings: There are certain opportunities for learning during the night shift, and three learning situations come to the fore: (1) the report situation, (2) the personal assessment round, where the nurses form their own picture of the patient, (3) in assessment prior to contact with the doctor on duty. Nurses learn from variations in patients' conditions and when they have to report their experience verbally. Learning does take place at night and gestalt psychology is a helpful tool for understanding how former knowledge and experience affect night nurses' learning., Conclusion: Knowledge developed during the night shift is a neglected field. There is a need for further investigations of what night nurses learn, and this knowledge ought to be integrated in the body of nursing knowledge.

The present paper reports a study on the daily activity of elderly people in a hospital suite, with presence infrared sensors. It is an attempt to produce parameters and indicators for the predictive analysis of the daily activity of fragile persons. A relationship is proposed between well being of the patient and the night and day activities alternation.

The mortality associated with hemodialysis (HD) remains high. Recent studies have found that a session time of 4 to 4.5 hours and an ultrafiltration rate of less than 10 cc/h/kg were each independently associated with a decreased mortality among HD patients. We started a thrice-weekly nocturnal HD program in May 2005 and have since enrolled a total of 16 patients. The Kt/V urea (2.6 +/- 0.65 vs. 1.2 +/- 0.16, mean +/- SD, P < .05) and serum phosphorus (4.4 +/- 1.1 v 5.3 +/-1.3 mg/dL, P =.049) values obtained 6 months after enrollment in the nocturnal HD program were significantly better than the baseline values obtained before the initiation of the nocturnal HD program. The ultrafiltration rate was 5.9 +/- 1.7 mL/h/kg 6 months after patients participated in the nocturnal HD program, whereas the rates for these same patients at baseline was 10.3 +/- 4.5 mL/h/kg. Psychosocial assessments were performed at baseline and again at 6 months. No difference was seen in the results of these assessments. We conclude that patients receiving long, in-center thrice-weekly nocturnal HD have a decrease in serum phosphate, an improvement in urea clearance, and a reduction in ultrafiltration rate to less than 10 mL/h/kg. This therapy appears to have no negative impacts on a variety of quality of life measures.

Frequent hemodialysis is currently conducted in a limited number of pediatric dialysis centers. However, the preliminary experience with children who have undergone procedures such as "daily" intensive hemodiafiltration and nocturnal hemodialysis has been positive, with the allowance for unrestricted diets and fluid intake, the lack of need for phosphate binders, excellent metabolic and blood pressure control, and, in the case of hemodiafiltration, excellent growth. The provision of frequent daily hemodialysis with the NxStage System has also recently been introduced to pediatrics. An overview about what is currently understood regarding the technical and clinical application of these approaches to therapy for children with end-stage renal disease form the basis for this article and highlight the impact of the procedures to date and the need for additional experience and collaborative data collection.

Sleep is a vital activity of daily living as it restores and refreshes. However, there are environmental, physiological and psychological factors that can affect normal sleep patterns. There are many ways in which nurses can help patients achieve a good night's sleep. This article discusses environmental, non-pharmacological and pharmacological interventions that can be used to promote sleep in hospital and community settings.

As with most things in life, this form of treatment is not for everybody. In my opinion, it is an option that should be explored if it is available. I have come to the conclusion that the advantages of nocturnal hemodialysis outweigh any of the possible disadvantages that there is no decision to make. My quality of life is so much better that I cannot envision going back to standard treatments. This is something that each patient will have to decide for themselves. Nocturnal dialysis has changed my life. For the better, even better than the few years of transplant, for this I thank my doctors, nurses and everyone else who has helped me along the way.

Objectives: To improve nighttime sleep in nursing home patients., Design: Controlled clinical trial., Setting: Eight community nursing homes enrolled two at a time., Participants: Of 1,077 patients assessed in the eight nursing homes, 638 (59%) were eligible, and consent was obtained for 273 (43% of those eligible). Of the 230 who underwent baseline assessments, 173 completed the immediate-intervention phase of the trial (77 in the intervention group and 96 in the control group). A total of 160 subjects completed the intervention (77 in the immediate-intervention group and 83 in the delayed-intervention phase)., Intervention: Trained research staff provided the intervention, which included daytime physical activity and attempts to keep subjects out of bed, evening bright light exposure, a consistent bedtime routine, nighttime care routines designed to minimize sleep disruption, and strategies to reduce nighttime noise. Subjects from one nursing home received the intervention (Group 1), whereas subjects in the second nursing home served as a control group (Group 2); then Group 2 received the intervention., Measurements: Primary outcomes included measures of sleep recorded using wrist actigraphy in all subjects and polysomnography in a subgroup of subjects. Secondary measures included assessments of mood and behavior using the Neuropsychiatric Inventory, the Geriatric Depression Scale, and behavioral observations., Results: There were no significant differences in any of the primary actigraphic sleep outcome measures between the intervention and control group after the immediate-intervention phase of the trial. In the 160 subjects who completed the intervention, there were no significant changes in any actigraphic measure of nighttime sleep, nor were there any significant changes in measures of sleep in the 45 subjects who had baseline and intervention polysomnography., Conclusion: This multicomponent, nonpharmacological intervention conducted by trained research staff had no effect on nighttime sleep in this sample of nursing home patients. Enhanced nonpharmacological interventions should be developed and tested and combined with environmental interventions to mitigate noise when feasible. Adjunctive drug therapy may be needed to improve sleep in a substantial proportion of this population and should be tested in addition to nonpharmacological interventions in rigorous clinical trials.

Sleep deficit is not uncommon in cardiac surgery patients, but research in this area is limited. This article examines the processes involved in sleep and how promoting these processes can optimise recovery in cardiac surgery patients. The two main parts of sleep, non-rapid eye movement and rapid eye movement, are believed to be responsible for the physical and psychological repair of the body. The combination of surgical injury, underlying disease and increased stress levels during hospitalisation for cardiac surgery increases the need for this repair. Nurses with a good understanding of sleep theories and the nursing process can use sleep and rest as an intervention to promote healing and prevent further injury after surgery.

Background: Patients with end-stage renal disease (ESRD) have a high prevalence of sleep disorders, which are not improved by conventional hemodialysis (CHD). Although sleep disorders are commonly associated with complaints of excessive daytime sleepiness, the severity and pathogenesis of daytime sleepiness has not been evaluated objectively in patients with ESRD. Nocturnal hemodialysis (NHD) is a new technique that provides better clearance of uremic toxins than CHD and, consequently, may improve sleep quality and daytime sleepiness. The authors wished to determine the severity and pathogenesis of daytime sleepiness in patients with ESRD and evaluate the impact of NHD., Methods: Sleep quality was monitored by overnight polysomnography, and daytime sleepiness was assessed by the multiple sleep latency test (MSLT). These measurements were performed in 24 patients (15 men and 9 women, 44 +/- 10 years) while on treatment with CHD and were repeated in 15 patients after conversion to NHD., Results: The majority (54%) of patients on CHD were pathologically sleepy (somnolent group, mean sleep latency <5 minutes), and, in comparison with the remaining patients (alert group, mean sleep latency >5 minutes), their blood urea nitrogen (BUN; 77.9 +/- 9.8 v 60.2 +/- 12.0 mg/dL, P < 0.001; 27.8 +/- 3.5 v 21.5 +/- 4.3 mmol/L; P < 0.001), and periodic limb movement (PLM) index (57 +/- 47 v 6 +/- 10/hr; P = 0.002) were significantly higher. Furthermore, sleep latency was correlated with BUN (R = 0.58, P = 0.008). After conversion to NHD, there was a significant fall in BUN and the severity of sleep apnea, but the overall frequency of PLM and sleep fragmentation remained elevated. Nevertheless, there was a trend for the Somnolent group to become less sleepy on NHD, and this was associated with a modest reduction in the frequency of PLM., Conclusion: Excessive daytime sleepiness occurs in approximately 50% of patients with ESRD. The etiology appears to be related both to uremia and sleep fragmentation associated with PLM., (Copyright 2003 by the National Kidney Foundation, Inc.)

A 42-year-old man with end-stage renal disease (ESRD) was referred for conversion to nocturnal hemodialysis (NHD) therapy from conventional hemodialysis (CHD) therapy because of refractory intermittent claudication secondary to peripheral arterial disease (PAD). The patient was initiated on CHD therapy in 1976 and subsequently had undergone two unsuccessful renal transplantations. While on CHD therapy, his clinical course was complicated by worsening vascular and soft-tissue calcification. Extensive dystrophic soft-tissue calcification was noted bilaterally in his hands, lower extremities, and sacral region, requiring surgical excision. Lower-extremity arterial Doppler scans documented vascular calcification and a pronounced decrease in peripheral arterial flow bilaterally. After conversion to NHD therapy (7.5 h/session five times weekly), the patient became symptom free and had significant clinical improvements in (1) hemodynamics, measured by clinic blood pressure and two-dimensional echocardiography, (2) biochemical profile, and (3) a sustained improvement in arterial Doppler flow measured by duplex Doppler ultrasound. We conclude that NHD was able to improve lower-extremity PAD in our patient. Further observational and interventional studies are required to investigate the therapeutic potential of NHD for the treatment of PAD in patients with ESRD., (Copyright 2003 by the National Kidney Foundation, Inc.)

We have developed an automated surveillance system based on passive infra-red sensors. Eight sensors were installed in a hospital room. A computer automatically captured data from the sensors every night from 21:00 until 06:00 the following morning. The sensors were polled twice per second and when a sensor was activated by movement, the event and time were recorded in a data file. At the end of the surveillance period the program analysed the data and generated a report showing the activities taking place in the room and their times. Four elderly patients were observed for a total of 97 nights. A total of 1637 possible sequences of movements by the patient and the hospital staff were detected. The computer was able to identify 1450 sequences (89%) correctly, in comparison with manual analysis. Only 10 movements (0.6%) were undetected by the system; all were very short sequences (five or six activations of the sensors). The system was generally capable of detecting and classifying all major movements in the room.
