Influence of mothers' nighttime responses on the sleep-wake rhythm of 1-month-old infants.

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.

Eficacia de un plan de cuidados de enfermería específico para el paciente con delirio / Effectiveness of a Specific Nursing Care Plan for the Patient with Delirium

RESUMEN Introducción: El síndrome confusional agudo o delirio es un trastorno psiquiátrico severo frecuente en pacientes mayores ingresados, tiende a agravarse en las horas del final de la tarde y nocturnas, con un gran impacto en los cuidados nocturnos. Objetivos: Evaluar la eficacia de los cuidados de enfermería específicos ante el delirio nocturno en pacientes hospitalizados. Métodos: Ensayo clínico cuasi-experimental en dos unidades de hospitalización de Medicina Interna de un hospital de alta complejidad. Se identificaron un grupo control y un grupo experimental, mediante muestreo de conveniencia. En ambos grupos, se seleccionaron pacientes con delirio, mediante la escala validada Intensive Care Delirium Screening Checklist. Se expuso al grupo experimental a plan de cuidados específico basado en bibliografía y plan de cuidados estándar al grupo control. Sobre resultados de indicadores de delirio, pre y posaplicación de planes de cuidados en ambos grupos, se realizaron pruebas de contraste (ANOVA, t-Student y Chi2-test de Fisher). Resultados: Con incidencia de 12-15 por ciento, los grupos control y experimental mostraron resultados homogéneos en el test del delirio PRE (p > 0,05). La edad, motivo de ingreso, género, y número de interrupciones durante el sueño, no mostraron repercusión sobre los resultados de delirio. Tras la aplicación de los planes de cuidados, el grupo experimental mostró reducción significativa de los índices de delirio (p < 0,05), y no se obtuvieron cambios significativos en el grupo control (p > 0,05). Conclusiones: El plan de cuidados específico a pacientes con delirio demostró ser eficaz al mejorar los indicadores del test de delirio y evitar el empeoramiento del cuadro(AU)

ABSTRACT Introduction: Acute confusional syndrome or delirium is a severe psychiatric disorder of frequent presentation in hospitalized elderly patients. It worsens likely in the late afternoon and evening hours, with a great impact on night care. Objectives: To evaluate the effectiveness of specific nursing care for sundown delirium in hospitalized patients. Methods: Quasi-experimental clinical trial in two hospitalization units of internal medicine of a high-complexity hospital. A control group and an experimental group were identified by convenience sampling. In both groups, patients with delirium were selected, using the validated scale Intensive Care Delirium Screening Checklist. The experimental group was exposed to a specific care plan, considering the bibliography; and the control group was exposed to a standard care plan. Regarding the results of delirium indicators, before and after the application of the care plans in both groups, contrast tests were performed (ANOVA, t-Student and Fisher's Chi-square test). Results: With an incidence of 12-15 percent, the control and experimental groups showed homogeneous results in the delirium test PRE (p >0.05). Age, reason for admission, gender, and number of interruptions during sleep did not show repercussion on delirium results. After the application of the care plans, the experimental group showed a significant reduction in delirium rates (p < 0.05), and no significant changes were obtained in the control group (p >0.05). Conclusions: The specific care plan for patients with delirium was shown to be effective in improving the indicators of the delirium test and avoiding the worsening of the health status(AU)

Napping on night-shifts among nursing staff: A mixed-methods systematic review.

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.

Acute myocardial infarction and primary percutaneous coronary intervention at night time / Infarto agudo do miocárdio e intervenção coronariana percutânea primária no período noturno

Background: Primary percutaneous coronary intervention is the preferred treatment in ST-elevation myocardial infarction. At night period, the delay until performing primary percutaneous coronary intervention may be determinant to prognosis worsening. Objective: To analyze the results of primary percutaneous coronary intervention performed at day and night periods. Methods: Cohort study that included patients admitted with ST-elevation myocardial infarction who underwent primary percutaneous coronary intervention from December 2013 until December 2016 in a ST-elevation myocardial infarction reference hospital of a metropolitan region in Brazil, followed from admission to hospital discharge or death, compared according to time of primary percutaneous coronary intervention (night or day). Statistical analysis comprehended the Chi-square test, the Fisher test, the Student's t-test and the analysis of variance, with significance level of 5%. Results: 446 patients were submitted to primary percutaneous coronary intervention, 159 (35.6%) at night time and 287 (64.4%) at day time. No differences were found between the two groups concerning clinical baseline characteristics. Door-to-balloon time (101 ± 81 minutes vs. 99 ± 78 minutes; p = 0,59) and onset-to-ballon time (294 ± 158 minutes vs. 278 ± 174 minutes; p = 0,32) did not differ between the groups. The incidence of combined major adverse cardiac events (15.1% vs. 14.3%; p = 0,58) and in-hospital mortality (9.4% vs. 8.0%; p = 0,61) were similar between the groups, as well as length of hospital stay (6.0 ± 4 days vs. 4.9 ± 4 days; p = 0,91). Conclusion: Primary percutaneous coronary intervention at night time showed similar results as the procedure performed at day time, without significant increase of in-hospital adverse events, length of stay or mortality

The use of overnight oximetry in neonates: A literature review.

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.

Low-Dose Nocturnal Dexmedetomidine Prevents ICU Delirium. A Randomized, Placebo-controlled Trial.

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. Clinical trial registered with www.clinicaltrials.gov (NCT01791296).

Impact of nighttime Rapid Response Team activation on outcomes of hospitalized patients with acute deterioration.

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.

Night-time care routine interaction and sleep disruption in adult cardiac surgery.

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.

[Intervention to reduce the impact of light and noise on sleep in an emergency department observation area]. / Intervención para reducir la repercusión en el sueño de la luz y el ruido en áreas de observación de urgencias.

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.

OBJETIVO: Conocer la calidad del descanso nocturno tras una intervención para minimizar la presencia de luz y el ruido nocturnos en las áreas de observación de urgencias (AOU) de un hospital urbano. METODO: Se realiza un ensayo clínico cuasiexperimental con un grupo preintervención (Grupo PRE) y otro posterior (Grupo POS) a la intervención, mediante cuestionario ad hoc sobre repercusión de luz y ruido en la calidad del descanso nocturno en el AOU del Hospital Clínic de Barcelona. La intervención consistió en cambios estructurales para reducir luz y el ruido ambientales, así como la instauración de un procedimiento normalizado de trabajo para modificar los planes de cuidados nocturnos. RESULTADOS: Se incluyeron en el Grupo PRE 50 enfermos y 371 en el Grupo POS. El grupo PRE declaró haber tenido un buen descanso en un 72% de los casos frente al 91% del grupo POS (p < 0,001). Factores como el dolor, las intervenciones enfermeras o el sueño diurno no repercutieron en la calidad del sueño. CONCLUSIONES: La luz y el ruido ambientales influyen en el descanso nocturno en AOU más que otras variables conocidas. Intervenciones sobre la luz y el ruido pueden mejorar objetivamente el descanso nocturno de los pacientes.

Improving the Patient's Experience With a Multimodal Quiet-at-Night Initiative.

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.

[Nighttime restlessness in people with dementia in residential care: an explorative field study]. / Nachtelijke onrust bij personen met dementie in woonzorgcentra: een verkennende veldstudie.

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.

The effect of nocturnal patient care interventions on patient sleep and satisfaction with nursing care in neurosurgery intensive care unit.

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.

Tucking patients in at night offers reassurance and improves sleep.

Relationship between nighttime vital sign assessments and acute care transfers in the rehabilitation inpatient.

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.

Statistical analysis plan for the Stroke Oxygen Study (SO2S): a multi-center randomized controlled trial to assess whether routine oxygen supplementation in the first 72 hours after a stroke improves long-term outcome.

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).

Validación de una escala de satisfacción con el cuidado nocturno de enfermería / Validation of a satisfaction scale for night nursing care

Con el objetivo de validar la escala The Night Nursing Care Instrument (NNCI) para la evaluación de la satisfacción con el cuidado enfermero nocturno en pacientes y enfermeros; entre enero y junio de 2011 se realizó en Medellín (Colombia) un estudio descriptivo de corte transversal con la participación de 194 pacientes hospitalizados en una institución de salud y de 34 enfermeros que tenían turnos nocturnos en el mismo hospital. Se utilizó la NNCI de 11 ítems, que evalúa en enfermeros y pacientes la satisfacción con los cuidados nocturnos de enfermería. Se hizo: a) traducción y retrotraducción del instrumento, b) validación semántica, c) validación de constructo con análisis de componentes principales, d) evaluación de la consistencia interna, y e) comparación de los ítems de la escala entre enfermeras y pacientes con un análisis de ANOVA de un factor. Los resultados mostraron en la validación factorial que la escala tiene tres dimensiones (intervenciones enfermeras, tratamiento médico y evaluación) en enfermeros y pacientes. La confiabilidad fue de 0,91 en enfermeros y 0,88 en pacientes. El 95,6 % de los pacientes y el 55,9 % de los enfermeros están satisfechos con el cuidado nocturno, diferencia que es estadísticamente significativa. La conclusión final de este estudio es que la escala NNCI es un instrumento con buena validez y confiabilidad y que puede ser utilizado en Colombia para evaluar la satisfacción de enfermeros y pacientes con el cuidado nocturno de enfermería(AU)

Aiming to validate The Night Nursing Care Instrument (NNCI) for evaluating satisfaction with night nursing care of patients and nurses, a cross sectional descriptive study, where 194 patients hospitalized in a health care institution and 34 nurses who had night shifts in the same hospital, was conducted between January and June 2011 in Medellin (Colombia). 11 items NNCI was used, it evaluates night nursing care satisfaction of nurses and patients. The instrument was: a) translated and retro-translated, b) semantically validated, c) construct validity with main component analysis was made, d) internal consistency was evaluated, and e) item comparison among nurses and patients with ANOVA analysis of a factor was made. Results showed in factorial validation, that the scale has three dimensions (Nurses interventions, medical treatment and evaluation) in nurses and patients. Reliability was 0,91 in nurses and 0,88 in patients. 95,6 % of patients and 55.9% of nurses were satisfied with nigh care, statistically significant difference. It was concluded that NNCI is an instrument with great validity and reliability and it can be used in Colombia to evaluate nurses' and patients' satisfaction with night nursing care(AU)
