O trabalho terceirizado e por turnos está associado ao aumento do risco de COVID-19? Descobertas de um estudo com trabalhadores da mineração / Is outsourced and shift work associated with an increased risk of COVID-19? Findings from a study about mining workers

Resumo Objetivos: investigar os fatores de risco sociodemográficos e ocupacionais associados à infeção por COVID-19 em trabalhadores da mineração. Métodos: estudo de coorte retrospectivo com dados secundários dos trabalhadores de uma empresa multinacional de mineração, de março de 2020 a abril de 2021. Casos de COVID-19 foram definidos por meio do resultado do teste reação em cadeia da polimerase (PCR) positivo para SARS-CoV-2. Riscos relativos (RR) para testes positivos foram obtidos por regressão de Poisson. Resultados: dos 10.484 trabalhadores testados, 2.578 (24,6%) tiveram pelo menos um resultado positivo. Foi realizada uma média de 4,0 (desvio-padrão: 3,6) testes para cada trabalhador, totalizando 41.962 testes. A maioria dos trabalhadores eram do sexo masculino (88,3%), com idade entre 30 e 39 anos (38,7%), terceirizados (74,1%) e que não trabalhavam em turnos (70,5%). No modelo múltiplo, os trabalhadores terceirizados (RR: 1,39; intervalo de confiança de 95% [IC95%]: 1,27;1,51) e trabalhadores por turnos (RR: 1,10; IC95%: 1,01;1,20) apresentavam maior risco de infecção quando comparados com seus homólogos. Conclusões: os trabalhadores terceirizados e por turnos exibiram maior risco de infecção pelo SARS-CoV-2 quando comparados com seus homólogos. Portanto, é necessário fornecer monitoramento contínuo com oferta regular e adequada de testes para mitigação e prevenção da COVID-19 nestes grupos ocupacionais.

Abstract Objectives: to investigate the sociodemographic and occupational risk factors associated with COVID-19 infection in mining workers. Methods: a retrospective cohort study, using secondary workers' health data from a multinational mining company, from March 2020 to April 2021. A COVID-19 case was defined based on a SARS-CoV-2 positive result in a polymerase chain reaction (PCR) test. Risk ratios (RRs) for positive testing were estimated using Poisson's regression model. Results: of 10,484 workers, 2,578 (24.6%) had at least one positive result for COVID-19. Each worker underwent an average of 4.0 (standard deviation: 3.6) tests, totaling 41,962 PCR tests. Most of the evaluated workers were male (88.3%), aged from 30 to 39 years (38.7%), outsourced (74.1%) and non-shift workers (70.5%). Our multivariate model showed that outsourced (RR: 1.39; 95% confidence interval [95%CI]: 1.27;1.51) and shift workers (RR: 1.10; 95%CI: 1.01;1.20) had a higher risk of SARS-CoV-2 infection than their counterparts. Conclusions: outsourced and shift workers have a higher risk of COVID-19 infection than their counterparts. Therefore, it is necessary to provide continuous monitoring with regular and adequate testing for mitigation and prevention of COVID-19 in these occupational groups.

Research progress on the relation and related mechanism of night shift work and cardiovascular disease / 中华劳动卫生职业病杂志

Cardiovascular disease is a class of diseases involving the heart or blood vessels, which accounts for about one-third of all deaths worldwide each year. Unhealthy diet, lack of physical activity, smoking and excessive alcohol consumption are all risk factors for cardiovascular disease. With the increasing number of night shift workers, the number of patients with cardiovascular disease has increased, and night shift work has gradually become a risk factor of cardiovascular disease. At present, the mechanism of cardiovascular disease caused by night shift work is still unclear. This review summarizes the relationship between night shift work and cardiovascular disease and its related biochemical indicators, and discusses the research on related mechanisms.

Effects of life satisfaction and shift work and their interaction on cumulative fatigue in petrochemical employees / 环境与职业医学

Background Cumulative fatigue without intervention will seriously threaten the physical and mental health of workers. Shift work and life satisfaction are strongly associated with fatigue accumulation. Objective To explore the effects of life satisfaction, shift work, and their interaction on cumulative fatigue in petrochemical employees, and to provide a scientific basis for preventing cumulative fatigue. Methods All staff of a petrochemical enterprise were selected by cluster sampling for a cross-sectional study from July to October 2021 in Jiangsu Province. A questionnaire designed by the project team was used to collect information on shift work; and life satisfaction and cumulative fatigue were investigated by the World Health Organization Five-item Well-Being Index and the Self-diagnosis Checklist for Assessment of Worker’s Fatigue Accumulation respectively. A logistic regression model was used to analyze the influences of life satisfaction and shift work on cumulative fatigue. Multiplicative and additive models were applied to analyze the interaction effect of life satisfaction and shift work. Results A total of 4066 questionnaires were returned, of which 3763 were valid, with an effective recovery rate of 92.5%. The percentage of cumulative fatigue in the petrochemical employees was 63.2% (2377/3763), and the percentages of low life satisfaction and shift work in the petrochemical employees were 53.6% (2016/3763) and 54.2% (2041/3763), respectively. The results of univariate analysis showed no significant difference in cumulative fatigue among different marital status groups (P=0.176), and there were statistically significant differences in cumulative fatigue among the petrochemical employees in different groups of age, gender, educational level, average monthly income, job title, length of service, working hours, night shift, smoking, drinking, physical exercise, life satisfaction, and shift work (P<0.001). After adjustment for covariates such as age, gender, educational level, average monthly income, job title, length of service, working hours, night shift, smoking, drinking, and physical activity, the unconditional logistic regression model showed that the risk of reporting cumulative fatigue in high life satisfaction participants was 0.129 (95%CI: 0.109, 0.154) times of that in participants of low life satisfaction; the risk of reporting cumulative fatigue in shift work participants was 3.792 (95%CI: 2.713, 5.300) times of that in no shift work participants; and the risk of reporting cumulative fatigue in participants with both high life satisfaction and shift work was 0.105 (95%CI: 0.081, 0.135) times of that in participants with low life satisfaction and shift work. The relative excess risk due to interaction, the attributable proportion due to interaction, and the synergy index of coexisting life satisfaction and shift work were −5.504 (95%CI: −7.247, −3.760), −4.728 (95%CI: −7.575, −1.880), and 0.029 (95%CI: 0.002, 0.351) respectively, which suggested that life satisfaction and shift work have an additive interaction effect on cumulative fatigue. A significant multiplicative interaction was also found between life satisfaction and shift work (OR=0.688, 95%CI: 0.476, 0.936). Conclusion Life satisfaction and shift work are the influencing factors of cumulative fatigue among petrochemical employees, and they interact with each other on the risk of cumulative fatigue. High life satisfaction can reduce the risk of accumulated fatigue associated with shift work.

Effect of night shift work and overweight/obesity on blood pressure of workers in chemical fiber industry / 中国职业医学

{L-End}Objective To analyze the effects of night shift work and overweight/obesity on blood pressure of workers in chemical fiber industry. {L-End}Methods A total of 1 004 workers of a chemical fiber factory were selected as the study subjects using convenient sampling method, and their blood pressure and body mass index were measured. Multiple linear regression model was used to analyze the relationship between night shift work and blood pressure, and multiple logistic regression was used to assess the independent impact and combined impact of night shifts and overweight/obesity on the risk of hypertension. {L-End}Results Compared with the non-night shift workers, the prevalence of hypertension in night shift workers was increased (5.3% vs 13.0%, P<0.05), with elevated systolic and diastolic blood pressure (both P<0.05). The results of multiple linear regression analysis showed that the systolic blood pressure and diastolic blood pressure of the night shift workers were higher than those of the non-night shift workers (both P<0.05), and the systolic blood pressure and diastolic blood pressure of overweight/obesity workers were higher than those of non-overweight/obesity workers (both P<0.01). The results of multiple logistic regression analysis showed that the risk of hypertension in night shift workers and overweight/obesity workers was higher than that in non-night shift workers and non-overweight/obesity workers [odds ratio (OR) and 95% confidence interval (CI) were 2.49 (1.04-5.99) and 2.65 (1.77-3.95), both P<0.05]. Night shift work and overweight/obesity showed a synergistic effect on blood pressure of workers. Compared to non-overweight/obesity non-night shift workers, overweight/obesity night shift workers had a higher risk of hypertension (OR=4.93, 95%CI: 1.70-14.29, P<0.01). {L-End}Conclusion Night shift work could lead to elevated blood pressure in workers in the chemical fiber industry, which is a potential risk factor for hypertension. The synergistic effect of night shift work and overweight/obesity may contribute to the increased risk of hypertension.

Correlation between insomnia and job performance in shift nurses / Монголын Анагаах Ухаан

@#Sleep and wakefulness are physiological processes in our lives that are regulated by circadian rhythms. The level of melatonin, the "sleep hormone", increases with the onset of darkness, and its production slows down in the morning. Exposure to artificial light at night disrupts our circadian rhythm and the processes it controls. Shift work is when an individual works from 9 am to 5 pm. But the night shift refers to the time when a group of workers who work at night in factories and enterprises work in the evening or at night, especially from 4 p.m. to 8 a.m. according to a regular schedule. One in five people in industrialized countries work night shifts, and studies in America and Europe show that between 15 and 30% of adult workers have some form of shift work. Between 10% and 30% of shift workers meet the diagnosis of shift work disorder (SWD). 5-10% of shift workers experience severe shift insomnia and sleepiness. At least ¾ of shift workers suffer from insomnia. Excessive sleepiness usually occurs during shifts (mainly at night) and is associated with impaired cognitive ability due to the need for sleep and reduced alertness, and decreased alertness reduces performance. Job performance is influenced by many workplace environmental factors, including workload, coworker relationships, stress levels, and extended hours. A nurse specialist provides nursing care by monitoring and evaluating 24 hours a day, and by working night shifts, the circadian system of sleep is disturbed, causing sleep problems and insomnia. When examining how night shift work affects nurses' ability to concentrate, the decline in concentration (33.3%) was twice as high as that of day shift nurses (16.7%). found that shift nurses who worked the night shift had higher rates of insomnia and chronic fatigue compared to nurses who stopped working the night shift. Lack of sleep manifests as a decline in cognitive functions such as attention, decision making, and reaction time. These cognitive and functional declines can negatively affect quality of life and lead to impaired job performance. An Australian study by Winwood et al found that fatigue associated with night shifts increases the risk of human error and injury, and negatively affects the quality of patient care. Lack of sleep significantly affects nurses' alertness, concentration, and job performance. This review article discusses the relation between shift work-related sleep and job performance based on international research findings.

Association of long working hours and shift work with occupational stress in level A tertiary hospitals / 预防医学

Objective@#To examine the association of long working hours and shift work with occupational stress among medical staff in level A tertiary hospitals, so as to provide insights into promotion of physical and mental health among medical personnel. @*Methods@#One level A tertiary hospital was sampled using a stratified cluster sampling method from southern and northern Xinjiang Uygur Autonomous Region, and all medical personnel were recruited from these two hospitals. Participants' demographics, working duration, and working in shifts were collected using questionnaires, and occupational stress was measured using the Core Scale for Measurement of Occupational Stress proposed by National Institute for Occupational Health and Poison Control, Chinese Center for Disease Control and Prevention. The associations of long working hours (weekly working duration of >40 hours) and shift work with occupational stress were examined using a multiple linear regression model.@*Results@#A total of 2 529 questionnaires were allocated, and 2 262 were valid, with an effective rate of 89.44%. The respondents had a mean age of (35.12±8.71) years, and included 1 696 women (74.98%). Of all respondents, there were 722 doctors (31.92%), 1 033 nurses (45.67%), 361 medical or pharmaceutical technicians (15.96%), 1 808 with long working hours (79.93%) and 1 264 with shift work (55.88%). The score of occupational stress was (44.79±8.49) points, and the prevalence of occupational stress was 28.69% among respondents. Multiple linear regression analysis showed that after adjustment for age, marital status, length of service, position, smoking and physical exercise, long working hours (>40 h, β'=0.124; >48 h, β'=0.175; ≥55 h, β'=0.323) and shift work (β'=0.203) were influencing factors for occupational stress among medical personnel（P<0.05）; however, there was no interaction between long working hours and shift work (P>0.05). @*Conclusion@#Long working hours and shift work may increase the risk of occupational stress among medical personnel in level A tertiary hospitals.

Foram testadas IL-6, TNF?- e IL-10, contudo estatisticamente inexpressivas. Quanto à metabolômica, esta apresentou 6 metabólicos diferencialmente expressos entre os turnos com destaque para a C-16 esfinganina e o PI (0-20:0/21:0) mais concentrados no noturno e duplo ou triplo vínculos associados ao "sono não restaurador", "alteração da memória e da concentração" e "diminuição dos reflexos". O metabólito PC(2:0/O-16:0)[U], predominante no diurno, apresentou associação com "alteração da memória e da concentração" e "episódios de choro e vontade chorar". Conclusões: Os resultados comprovaram a associação da SDE com os sinais e sintomas de privação do sono e com metabólitos diferencialmente expressos conforme o turno de trabalho.

Introduction: Shift work exposes hospital nursing professionals to sleep deprivation, which can lead to Excessive Daytime Sleepiness (EDS) and is associated with the immunological response, metabolism and physical, mental and emotional illness of workers. Pro-inflammatory interleukins and metabolites can be potential biomarkers for assessing sleep quality and health changes. Objective: To verify the occurrence of EDS in nursing workers who work with critically ill adult patients and possible associations with the conditions of health, with the serum concentration of interleukins and metabolites expressed according to the work shift. Method: it is a cross-sectional, correlational study, with a quantitative approach, carried out in a federal teaching hospital in the interior of Minas Gerais, Brazil. The population consisted of nursing workers from adult Intensive Care Units. Among 172 professionals, 124 met the inclusion criteria and participated in the research divided into three groups: daytime, nighttime and double or triple bonds. Three instruments were used to collect data: sociodemographic characteristics questionnaire, health conditions questionnaire and the Epworth Daytime Sleepiness Scale and, in addition, venous blood was collected to measure interleukins and metabolites. The data were tabulated and analyzed using the Statistical Package for the Social Sciences-SPSS 22.0. Among the tests used are: Variance Inflation Factor (VIF), Akaike Information Criterion (AIC), multicollinearity, multiple linear regression, logistic regression, chi-square, Mann-Whitney, Shapiro-Wilk and Kruskal-Wallis, in addition of Graph Pad Prism 7.0 software and Mass Hunter Qualitative v. 10.0. The study was approved by the EERP-USP Research Ethics Committee, according to opinion no. 3,950,501/2020. Results: 81.5% of participants were women who worked an average of 49h59min per week and slept an average of 5h50min. 37.1% reported pre-existing diseases, especially cardiovascular, endocrine, metabolic and neuropsychiatric diseases. 70.2% had EDS associated with nine variables, highlighting "non-restorative sleep", "episodes of crying and wanting to cry", "changes in memory and concentration" and "decreased reflexes". IL-6, TNF?- and IL-10 were tested, but they were statistically insignificant. As for metabolomics, this presented 6 metabolic variables differentially expressed between shifts, with emphasis on C-16 sphinganine and PI (0-20:0/21:0) more concentrated at night and double or triple bonds and associated with "sleep not restorative", "change in memory and concentration" and "decrease in reflexes". The metabolite PC (2:0/O-16:0)[U], predominant in the daytime, was associated with "change in memory and concentration" and "episodes of crying and wanting to cry". Conclusions: The results confirmed the association of EDS with the signs and symptoms of sleep deprivation and with metabolites differentially expressed according to the work shift.

Association between long working hours and occupational stress/fatigue accumulation in medical staff of tertiary grade A hospitals in Shanghai / 环境与职业医学

Background Long working hours are a common occupational health risk factor. The problem of long working hours and its impact on health of medical staff cannot be ignored. Objective To investigate long working hours in medical staff of tertiary grade A hospitals in Shanghai, and evaluate the relationships of long working hours with occupational stress and fatigue accumulation. Methods A total of 1531 medical staff in departments of emergency, internal medicine, surgery, intensive care unit (ICU), anesthesiology, and obstetrics and gynecology from 6 hospitals in 6 districts of Shanghai were selected using stratified random sampling. A structured questionnaire was used to collect information on social demographics, occupational characteristics, andbehavior and lifestyle. The Core Occupational Stress Scale (COSS) and the Self-diagnostic Questionnaire on the Accumulation of Fatigue of Laborers were used to assess occupational stress and fatigue accumulation condition. Chi-square test and Kruskal-Wallis H test were used to analyze the distributions of long working hours, occupational stress, and fatigue accumulation, log-binomial models were used to analyze the relationships of long working hours with occupational stress and fatigue accumulation, and job title stratified models were also constructed. Results The average weekly working hours of the study subjects was (47.84±11.40) h, 65.90% of the medical staff worked more than 40 h every week. The percentages of the weekly working hours categories of 41-48 h, 49-54 h, and ≥55 h were 31.42%, 13.46%, and 21.03%, respectively. The positive rates of occupational stress and fatigue accumulation were 25.87% and 65.64% respectively, and the differences among different age, gender, job title, education, length of service, and shift system groups were statistically significant (P<0.05). The results of log-binomial regression showed that after adjusting for gender, age, monthly income, marital status, education, physical exercise, smoking, job position, length of service, and shift system, weekly working hours were an influencing factor of occupational stress and fatigue accumulation (P<0.05). Compared with weekly working hours≤40 h, the risk, PR(95%CI), of reporting occupational stress and fatigue accumulation increased to 2.595 (1.989, 3.385) and 1.578 (1.349, 1.845) times respectively for weekly working hours≥55 h (P<0.001). The results of job title stratification analysis showed that the risk of occupational stress among physicians, nurses, and medical technicians increased when weekly working hours≥55 h versus ≤40 h, and the PR (95%CI) values were 2.003 (1.383, 2.902), 1.971 (1.068, 3.636), and 2.770 (1.220, 6.288), respectively (P<0.05). The risk of fatigue accumulation was increased in physicians when weekly working hour≥55 h versus ≤40 h, with a PR (95%CI) value of 1.594 (1.208, 2.103) (P<0.001). Conclusion Long working hours are common among medical personnel and related to the occurrence of occupational stress and fatigue accumulation.

Materials and Methods: A comparative cross-sectional study is devised including health-care profes-sionals working night shifts on rotation at a tertiary level health-care facility, using a semi-structured questionnaire which can test sleep deprivation, cognitive ability, and quality of life. The process is to ap-proach 309 probable study participants based on stratified random sampling, after exclusion of health-care professionals with other factors which may interfere with sleep deprivation testing. Discussion: The study protocol was set in such a way as to randomly include participants from all cadres of healthcare providers as per population proportion. By measuring the effects on cognitive effect and quality of life necessary steps can be taken to provide better quality of life and to decrease cognitive im-pairment, especially among health care professionals working night shifts.

DEVELOPMENT AND VALIDATION OF YOGA MODULE FOR OBSTRUCTIVE SLEEP APNEA

Background: Sleep is an essential component of human life because it provides for relaxation and recovery from the stresses of everyday living. Reduced sleep quantity or quality leads to sleep deprivation which may offer indirect dangers by affecting cognitive and physical performance and raising the chance of motor vehicle and occupational accidents. Insomnia chronic sleep debt snoring sleep apnea circadian rhythm disturbances (including shift work syndrome) RLS parasomnias and uncommon diseases such as narcolepsy are the most common sleep disorders found in sleep clinics according to experts. Obstructive Sleep apnea is a common disorder in which your breathing stops and starts periodically while you sleep.

Cardiovascular Risk Factors in Haul Truck Operators of the Mining Sector Working a Rotational Schedule

Abstract Background: Due to the growing concern about work-related social and health aspects, occupational health and safety has become relevant. Objective: This work aims to develop a model to assist cardiovascular risk management in a team of haul truck operators, who work in rotating shifts at a mining company in Brazil. Methods: This longitudinal study evaluated risk factors for cardiovascular diseases of 191 mineworkers at three times points - 2010, 2012, and 2015. In addition, the risk of developing cardiovascular diseases was calculated, and the risk factors were analyzed using the chi-square test, the U Mann-Whitney test, and binary logistic regression. The significance level was set at 5%. Results: In the study period, body weight, body mass index (BMI), waist-to-height ratio (WHR), systolic (SBP), and diastolic blood pressure (DBP), total cholesterol, high-density lipoprotein cholesterol (HDL-C), and triglycerides levels of the study group increased. In 2015, there was a high prevalence of alcohol intake, overweight or obesity, central obesity, inadequate WHR, high blood pressure, total cholesterol above 190 mg/dL, and triglycerides above 150 mg/dL. An association was identified between increased cardiovascular risk and age, SBP, HDL-C, low-density lipoprotein cholesterol (LDL-C), and elevated glucose levels. Conclusion: Intense interventions for reduction and prevention of elevated alcohol intake, blood pressure levels, WHR, metabolic syndrome, blood glucose, and LDL-C levels, and low HDL-C levels are needed. In addition, a close monitoring of mine workers over 38 years of age who smoke, consume alcoholic beverages, and have altered blood glucose levels is important.

Cardiovascular risk behavior among industrial workers in the Northeast of Brazil: a cluster analysis / Comportamento de risco cardiovascular entre trabalhadores industriais no nordeste do Brasil: uma análise de cluster

Abstract This research aimed to investigate the occurrence of clusters of cardiovascular risk behaviors and their association with social demographic and occupational characteristics in a population of industrial workers in the metropolitan area of Recife, Brazil. It was a transversal study with 727 workers of both genders. We identified cluster distribution from the variables: smoking, alcohol consumption, physical activity and waist circumference, by a combination of hierarchical and non-hierarchical analysis. We later tested the association with the social demographic and occupational variables with a multi-varied analysis. We have identified a protection cluster (sufficient physical activity, moderate alcohol consumption) and a risk cluster (high waist circumference, sedentarism, smoking, excessive alcohol consumption). The protection cluster was positively associated with night shift or variable shift work (RP: 1.66, IC95%: 1.26-2.17), and the risk cluster was associated with women (RP: 1.15, IC95%: 1.01-1.31). Cluster analysis allowed to identify that, for day shift workers and women, the shortest daytime outside the work environment can influence the adoption of cardiovascular risk behaviors.

Resumo Esta pesquisa teve como objetivo investigar a ocorrência de clusters de comportamentos de risco cardiovascular e sua associação com características sociodemográficas e ocupacionais em uma população de trabalhadores da indústria da região metropolitana de Recife, Brasil. Trata-se de um estudo transversal com 727 trabalhadores de ambos os gêneros. Identificou-se a distribuição do cluster a partir das variáveis: tabagismo, etilismo, atividade física e circunferência da cintura, por meio de uma combinação de análise hierárquica e não hierárquica. Posteriormente, testamos a associação às variáveis sociodemográficas e ocupacionais com uma análise multivariada. Identificamos a formação consistente de um cluster de proteção (atividade física suficiente, consumo moderado de álcool) e de um cluster de risco (circunferência da cintura elevada, sedentarismo, tabagismo, consumo excessivo de álcool). O cluster de proteção associou-se positivamente ao turno noturno ou turnos variáveis (RP: 1,66, IC95%: 1,26-2,17) e o cluster de risco esteve associado às mulheres (RP: 1,15, IC95%: 1,01-1,31). A análise de cluster permitiu identificar que, para trabalhadores diurnos e mulheres, a menor jornada diurna fora do trabalho pode influenciar na adoção de comportamentos de risco cardiovascular.

Condicionantes de calidad de los cuidados enfermeros durante el turno de noche / Factors Influencing Quality of Nursing Care during the Night Shifts

Introducción: El turno nocturno provoca efectos físicos y psicológicos en las enfermeras. Fatiga, estrés, ansiedad, alteraciones del sueño y percepción negativa del entorno laboral pueden condicionar la calidad del cuidado. Objetivo: Identificar las condiciones relacionadas con la calidad de los cuidados enfermeros durante los turnos de noche en los hospitales. Métodos: Se realiza una revisión sistemática según criterios PRISMA. Se utilizó como estrategia común en las bases consultadas la combinación de las palabras clave y booleanos: ("Quality of Care") AND ("Nurse"OR"Nurses") AND ("Night shift"OR"Shift"). Se exploraron las bases de datos PubMed, Cinahl, Scopus y Cochrane. Se Incluyeron ensayos, estudios transversales, revisiones y estudios cualitativos entre 2009 y 2018. Se excluyeron los que no cumplieron requisitos de contenido y criterios de evaluación de calidad metodológica descritos a priori. Se incluyeron 20 trabajos. Conclusiones: Para la mayoría de autores la calidad de los cuidados nocturnos es menor que durante el día y puede estar condicionada por exceso de horas trabajadas, percepción de salud, fatiga, calidad del sueño, menor ratio enfermera-paciente, menor apoyo institucional y menor satisfacción profesional. Los indicadores de calidad más utilizados fueron incidencia de úlceras por presión, errores en identificación de pacientes, errores de medicación, errores de comunicación, cuidados sin realizar, desmotivación profesional, despersonalización y retención institucional. La heterogeneidad de los estudios hace que pueda aumentar el sesgo en los resultados. Muchos indicadores descritos son evaluados mediante percepciones, ocasionalmente por métodos objetivos. La identificación de condicionantes clave en la calidad de cuidados nocturnos permite iniciativas institucionales de gran impacto(AU)

Introduction: The night shift causes physical and psychological effects on nurses. Fatigue, stress, anxiety, sleep disturbances and negative perception of the work environment can affect the quality of care. Objective: To identify the conditions related to the quality of nursing care during night shifts in hospitals. Methods: A systematic review was carried out according to PRISMA criteria. As a common strategy in the consulted databases, the combination of the following keywords and Booleans was used: ("Quality of Care") AND ("Nurse "OR "Nurses") AND ("Night shift "OR "Shift"). The PubMed, Cinahl, Scopus and Cochrane databases were explored. Trials, cross-sectional studies, reviews and qualitative studies between 2009 and 2018 were included. Those that did not meet content requirements and methodological quality assessment criteria described a priori were excluded. Twenty papers were included. Conclusions: For most authors, the quality of night care is lower than during the day and may be affected by an excess of working hours, health perception, fatigue, sleep quality, lower nurse-patient ratio, lower institutional support and lower professional satisfaction. The most frequently used quality indicators were incidence of pressure ulcers, patient identification errors, medication errors, communication errors, unperformed care, professional demotivation, depersonalization and institutional retention. The heterogeneity of the studies may increase bias in the results. Many of the indicators described are assessed by perceptions, occasionally using objective methods. The identification of key determinants in the quality of night care allows for high-impact initiatives at the institutional level(AU)
