Nursing workload in public and private intensive care units

Carga laboral de profesionales de enfermería en Unidad de Cuidado Intensivo según Nursing Activities Score

Highlights: La NAS es una herramienta que toma relevancia al momento de evaluar la carga de trabajo de los profesionales de enfermería. Se evidencia que el personal de enfermería está expuesto a altas cargas de trabajo que, en la mayoría de casos, supera lo sugerido por Consejos y Asociaciones de enfermería. Algunos factores que pueden afectar la carga de trabajo son el tipo de turnos de trabajo, sexo del profesional, tipo de UCI, el número de pacientes a cargo, entre otros. Es necesario evaluar la implementación de la NAS en distintos tipos de servicios para entender la situación y trabajo actual de los profesionales de enfermería. Introducción: Nursing Activities Score ha sido utilizada como un instrumento principalmente en la Unidad de Cuidados Intensivos para medir las actividades de enfermería, siendo esta la unidad que maneja pacientes de mayor complejidad para el cuidado. Objetivo: establecer la carga de trabajo, evaluada por Nursing Activities Score, y factores relacionados a la misma en Unidades de Cuidado Intensivo. Metodología: Revisión cualitativa tipo scoping Review, utilizando el método PRISMA. Búsqueda en las bases de datos CINAHL, LILACS, SCOPUS, SCIENCE DIRECT, SCIELO y PUBMED. Resultados: La muestra final se compone de 87 textos, que van desde el año 2007 hasta 2021. Se clasificaron en cinco categorías: Carga de trabajo en UCI, comparación entre unidades, carga de trabajo relacionada al personal de enfermería, carga de trabajo relacionada a las características de los pacientes y consecuencias de la carga de trabajo. Discusión: La revisión revela una carga de trabajo mayor al 50% en la mayoría de los estudios, esto debido a diferentes factores: principalmente las características particulares de los pacientes, no se observó una diferencia significativa entre unidades generales y especializadas, las cargas de trabajo elevadas suponen un factor de riesgo para la ocurrencia de eventos adversos. Conclusiones: Los resultados de esta revisión permiten evidenciar que el personal de enfermería está expuesto constantemente a altas cargas de trabajo. Esta carga de trabajo puede verse influenciada o influenciar diversos factores, como lo son las características de los pacientes a quienes se brinda atención o puede afectar positiva o negativamente la calidad de la atención de enfermería.

Comparison of nursing workload in a Pediatric Intensive Care Unit estimated by three instruments

OBJECTIVE

To compare the nursing workload using the Nursing Activities Score (NAS), Therapeutic Intervention Scoring System-28 (TISS-28) and Nine Equivalents of Nursing Manpower Use Score (NEMS) instruments in children admitted to a Pediatric Intensive Care Unit in a university hospital.

METHOD

A prospective cohort study performed in a Pediatric Intensive Care Unit, with a sample formed of all children hospitalized during the study period. Nursing workload was evaluated using the TISS-28, NEMS and NAS instruments, and further divided into two groups: Group 1 forming a category of basic activities items and Group 2 forming a category of other support and intervention activities.

RESULTS

The sample consisted of 490 Pediatric Intensive Care Unit admissions, totaling 4617 observations. NAS presented the best estimate of total working hours. TISS-28 and NEMS showed better agreement and the results showed strong correlations between NAS and TISS-28 and between NEMS and TISS-28. In Group 1 (basic activities), NAS(1) and TISS-28(1) showed moderate correlation, in Group 2 (specialized activities) the three instruments showed strong correlations.

CONCLUSION

NAS stood out in the evaluation of nursing workload and showed good correlation and agreement with the TISS-28.

The association between nurses' moral distress and sleep quality and their influencing factor in private and public hospitals in Iran

BACKGROUND

Nurses in their workplace, for a variety of reasons, always face moral distress that is an underlying issue in the nursing profession, which can lead to problems such as reduced quality and quantity of care and sleep disorder. Besides, given the increased privatization of hospitals, this study aimed to explore the association between nurses' moral distress and sleep quality and its comparison among nurses in private and public hospitals.

MATERIALS AND METHODS

This was a descriptive-analytical study involving 150 nurses working in Ilam Province hospitals. Sampling conducted using a multistage random sampling method. Data were collected through the questionnaire of sociodemographic characteristics, the Corley's Moral Distress Scale, and the Pittsburgh Sleep Quality Index. Data were analyzed using SPSS software version 22. Descriptive statistics such as frequency, mean, ANOVA, independent t-test, multiple linear regression, and Pearson correlation coefficient at the significant level of P < 0.05 were calculated.

RESULTS

The analysis revealed that moral distress was positively associated with sleep quality. Furthermore, the scores of nurses' moral distress and sleep quality were different in private and public hospitals, so that the level of moral distress in the public hospital and sleep quality in the private hospital was higher and lower, respectively, but the difference was not statistically significant. Moreover, sleep quality, and the type of employment was the most important predicting variables of moral stress (B = 1.86) and sleep quality (B = 2.39), respectively.

CONCLUSION

According to the study results, a positive and significant association was found between moral distress and nurses' sleep quality. It is recommended that appropriate strategies and training program be formulated by the health-care system to increase nurses' ability to combat moral distress adverse effects.

Organizational culture: prevention, treatment, and risk management of pressure injury

ABSTRACT Objectives: To identify the facilitating and complicating factors for the prevention and treatment of pressure injury (PI) in the management of hospitalized patient care. Methods: This is a cross-sectional study, conducted with 197 nursing professionals in three public hospitals. Results: Among the identified factors, it is noteworthy that 59% of respondents are unaware of the PI prevention protocol, 27% do not use clinical evaluation for daily sizing of professionals, more than 52% believe that no facilitating elements exist, and 76% argue that there are complicating elements for the prevention of PI. As for the treatment, a little over 60% reported that the patient and the injury are evaluated by nurses, with 54% of the procedures being prescribed by the physician and 46% of the therapy being performed by nursing technicians. Conclusions: We conclude that the prevention and treatment of PI require shared management, with integrated actions among the care executors.

Nursing workload in burn intensive care unit

ABSTRACT Objectives: To measure the nursing workload in the Burn Intensive Care Units and evaluate its association with clinical variables, length of stay, and outcome of hospitalization. Methods: Cross-sectional study carried out in a Brazilian public large hospital. The study included 33 patients. The nursing workload was assessed using the Nursing Activities Score (NAS) every 24 hours. We performed 447 Nursing Activities Score assessments. For the statistical analysis, Student’s t-test, ANOVA, and Spearman’s correlation test were used. The considered significant difference was 5% (p ≤ 0.05). Results: The Nursing Activities Score mean was 84% (± 4.4), which corresponded to 20.2 hours. There was an association between the nursing workload and the patient’s severity (p <0.010), burned body surface (p = 0.010), and hospitalization outcome (p = 0.020). Conclusion: Burn victims, assisted in the ICU, demanded a high nursing workload, which was influenced by clinical aspects and the hospitalization outcome. These findings point to the need to reconsider the nurse staffing related to this care profile.

Type of admission and nursing workload of critical patients: a cross-sectional study

BACKGROUND

According to the perception of nurses in the intensive care unit (ICU), surgical patients need more nursing care, thus requiring higher nursing workloads for these patients than those admitted as clinical patients. However, some study results on the relationship between the type of admission and the nursing workload are considered contradictory.

AIMS AND OBJECTIVES

To identify if the type of admission (clinical, emergency surgery or elective surgery) is a predictive factor of the nursing workload required by patients on the first day or throughout their stay in the ICU.

DESIGN

This was a quantitative cross-sectional study comprised of a retrospective analysis of clinical records of critical patients.

METHODS

Data were collected from 1 May 2015 to 30 September 2015 in a hospital located in São Paulo, Brazil. Nursing workload was measured using the Nursing Activities Score. The type of admission and the demographic and clinical variables of the patients were investigated. Multiple linear regression was used to identify nursing workload predictive factors, with 5% significance level.

RESULTS

In the analysed sample (n = 211; mean age of 60·3 ± 18·7 years), there was a prevalence of male gender (56·9%). A statistically significant difference (p = 0·025) was found between the type of admission and the nursing workload required for patients on the first ICU day. The Simplified Acute Physiologic Score (p = 0·009) was a predictor of nursing workload on the first day in the ICU, and the Logistic Organ Dysfunction System (p = 0·026) and mortality (p < 0·001) were predictors throughout the ICU stay.

CONCLUSIONS

The type of admission was not a predictive factor of the nursing workload required by critical patients.

RELEVANCE TO CLINICAL PRACTICE

Identifying the predictive factors of nursing workload favours the appropriate staffing of the critical unit by nurses. However, nurses should not consider the type of admission in predicting the nursing workload required by patients in the ICU.

Cognitive changes in nurses working in intensive care units

OBJECTIVE

To measure the levels of stress, anxiety, and depression of nurses working in ICUs, relating them to levels of attention before and after 24 hours.

METHOD

An observational, quantitative, analytical study with 18 nurses undergoing an inventory of stress, anxiety, and depression, as well as assessment of attention levels and psychomotor functioning.

RESULTS

Sixty-one percent showed positive for stress. Depression was observed in 33%; and anxiety in 99.9%. A strong correlation between stress and depression (ρ = 0.564 with p <0.05) and anxiety (ρ = 1 with p <0.05) was observed. There was a weak correlation between stress and task execution time in M2 (ρ = 0.055) for TMT A, a fact that did not occur in M0 (ρ = -0.249).

CONCLUSION

The study shows that the workload of the nurses working in 24-hour shifts in the ICU is correlated with high levels of stress, decreases in the attention process, and psychomotor decline.

Severity and workload of nursing with patients seeking admission to an intensive care unit

Abstract Objective: To identify the severity and workload of nursing with adult patients seeking admission to an Intensive Care Unit (ICU). Methods: A cross-sectional study with a quantitative, exploratory and prospective approach was performed, developed in a hospital in the state of São Paulo. Demographic data on patients were collected, the Simplified Acute Physiology Score III (SAPS III) was applied to assess the severity of patients and the Nursing Activities Score (NAS) was used to evaluate nursing workload, between July and August 2014. Results: The overall mean score of the SAPS III was 30.52 ± 18.39 and that of the NAS was 58.18 ± 22.29. The group of patients admitted to the ICU showed higher severity and higher workload of nursing compared to non-admitted patients. Non-admitted patients had an NAS of 53.85. Conclusion: The nursing workload in patients who were not admitted to the ICU was also high. The evaluation of workload in other contexts where patients are seriously ill is important. The workload assessment in other contexts where severely ill patients are found is evident.

Association between workload of the nursing staff and patient safety outcomes

OBJECTIVE To describe the workload of the nursing team and relate it with patient safety outcomes in clinical and surgical inpatient units of a university hospital. METHOD Cross-sectional study, carried out from October 2013 to September 2015. The factor under study was the workload, expressed as the ratio between the mean number of patients and the number of nursing professionals in 24 hours and in the day shifts. RESULTS The sample consisted of 157,481 patients, 502 nursing professionals and 264 observations of safety outcomes. The ratios of patients per nurse and per nursing technician in day shifts indicate a mean estimate of 14-15 and 5-6 patients per professional, respectively. There was a significant association between the workloads in the inpatient units and average length of stay, urinary infection related to invasive procedure and the satisfaction of patients with nursing care. CONCLUSION The increase in the workload of the nursing team had an impact on quality of care and safety for patients. An adequate staffing promotes a safer care environment.

Sizing of nursing staff associated with self-care promotion in a pediatric semi-intensive care unit

OBJECTIVES

To calculate and compare the nursing staff size associated with self-care promotion at a pediatric semi-intensive care unit.

METHODS

This was a prospective study in which 31 children and their caregivers participated. The nursing workload associated with each participant was evaluated at two different times (first and second hospital stays) using the Nursing Activities Score instrument. The first hospital stay corresponded to self-care promotion. Staff size was calculated according to the nursing hours recommended by the Nursing Activities Score instrument and by Conselho Federal de Enfermagem (COFEN) resolution no. 527/16, in the two hospital stays, and the results were compared.

RESULTS

The nursing workload in the first hospital stay (14.6 hours) was higher than the nursing workload in the second stay (9.9 hours) (p < 0.001). The Nursing Activities Score revealed that according to the nursing hours, the nursing staff size corresponded to 26 and 18 professionals in the first and second hospital stays, respectively, and to 15 professionals according to COFEN resolution no. 527/16.

CONCLUSION

The number of personnel responsible for promoting self-care in pediatric semi-intensive care units, according to the nursing hours suggested by the Nursing Activities Score, was higher than that recommended by the existing legislation. This demonstrates the necessity of reconsidering staff size for this healthcare profile.

Avaliação da carga de trabalho no pós-operatório de cirurgia cardíaca segundo o Nursing Activities Score

RESUMO Objetivo Identificar os fatores associados à carga de trabalho de enfermagem no cuidado a pacientes no pós-operatório de cirurgia cardíaca. Método Estudo de coorte prospectivo, conduzido com 187 pacientes da Unidade de Terapia Intensiva Cirúrgica (UTI) do Instituto do Coração. Os dados foram coletados nas primeiras 24 e 72 horas do paciente na UTI. A variável dependente foi a carga de trabalho calculada por meio do Nursing Activities Score (NAS) e as independentes foram de natureza demográfico-clínicas e escores de morbimortalidade. Para análise dos dados utilizou-se os testes de Wilcoxon-Mann-Whitney e de correlação de Spearman, e a regressão linear com modelo de efeitos mistos. Resultados A maioria dos pacientes era do sexo masculino (59,4%), com média de idade de 61 anos (±12,7) e 43,9% desenvolveram algum tipo de complicação no pós-operatório. Nas 24 horas, a carga de trabalho foi de 82,4% (±3,4) e foi de 58,1% (±3,4) nas 72 horas. Os fatores associados ao aumento do NAS foram: tempo de internação do paciente na UTI (p=0,036) e a presença de complicações (p<0,001). Conclusão A gravidade do paciente nas 24 horas, em oposição a inúmeros estudos, não influenciou no aumento da carga de trabalho, a qual se mostrou associada ao tempo de internação e às complicações.

Nursing Activities Score: an updated guideline for its application in the Intensive Care Unit

ABSTRACT Objective To describe nursing workload in Intensive Care Units (ICU) in different countries according to the scores obtained with Nursing Activities Score (NAS) and to verify the agreement among countries on the NAS guideline interpretation. Method This cross-sectional study considered 1-day measure of NAS (November 2012) obtained from 758 patients in 19 ICUs of seven countries (Norway, the Netherlands, Spain, Poland, Egypt, Greece and Brazil). The Delphi technique was used in expertise meetings and consensus. Results The NAS score was 72.8% in average, ranging from 44.5% (Spain) to 101.8% (Norway). The mean NAS score from Poland, Greece and Egypt was 83.0%, 64.6% and 57.1%, respectively. The NAS score was similar in Brazil (54.0%) and in the Netherlands (51.0%). There were doubts in the understanding of five out 23 items of the NAS (21.7%) which were discussed until researchers’ consensus. Conclusion NAS score were different in the seven countries. Future studies must verify if the fine standardization of the guideline can have a impact on differences in the NAS results.

The use of the Nursing Activities Score in clinical settings: an integrative review

Objective analyze how studies have approached the results obtained from the application of the Nursing Activities Score (NAS) based on Donabedian's model of healthcare organization and delivery. Method CINAHL and PubMed databases were searched for papers published between 2003 and March 2015. Results 36 articles that met the inclusion criteria were reviewed and double-coded by three independent coders and analyzed based on the three elements of Donabedian's health care quality framework: structure, process and outcome. The most frequently addressed, but not always tested, variables were those that fell into the structure category. Conclusion variables that fell into the process category were used less frequently. Beside NAS, the most frequently used variables in the outcome category were mortality and length of stay. However, no study used a quality framework for healthcare or NAS to evaluate costs, and it is recommended that further research should explore this approach.

Measuring professional satisfaction and nursing workload among nursing staff at a Greek Coronary Care Unit

Objective To explore potential associations between nursing workload and professional satisfaction among nursing personnel (NP) in Greek Coronary Care Units (CCUs). Method A cross-sectional study was performed involving 66 members of the NP employed in 6 randomly selected Greek CCUs. Job satisfaction was assessed by the IWS and nursing workload by NAS, CNIS and TISS-28. Results The response rate was 77.6%. The reliability of the IWS was α=0.78 and the mean score 10.7 (±2.1, scale range: 0.5-39.7). The most highly valued component of satisfaction was "Pay", followed by "Task requirements", "Interaction", "Professional status", "Organizational policies" and "Autonomy". NAS, CNIS and TISS-28 were negatively correlated (p≤0.04) with the following work components: "Autonomy", "Professional status", "Interaction" and "Task requirements". Night shift work independently predicted the score of IWS. Conclusion The findings show low levels of job satisfaction, which are related with nursing workload and influenced by rotating shifts.

[Use of scores to calculate the nursing workload in a pediatric intensive care unit]

OBJECTIVE

To assess the performance of the Nursing Activities Score in a pediatric intensive care unit, compare its scores expressed as time spent on nursing activities to the corresponding ones calculated using the Simplified Therapeutic Intervention Scoring System, and correlate the results obtained by both instruments with severity, morbidity and mortality.

METHODS

Prospective, observational, and analytical cohort study conducted at a type III general pediatric intensive care unit. The study participants were all the children aged 29 days to 12 years admitted to the investigated pediatric intensive care unit from August 2008 to February 2009.

RESULTS

A total of 545 patients were studied, which corresponded to 2,951 assessments. The average score of the Simplified Therapeutic Intervention Scoring System was 28.79±10.37 (915±330 minutes), and that of the Nursing Activities Score was 55.6±11.82 (802±161 minutes). The number of minutes that resulted from the conversion of the Simplified Therapeutic Intervention Scoring System score was higher compared to that resulting from the Nursing Activities Score for all the assessments (p<0.001). The correlation between the instruments was significant, direct, positive, and moderate (R=0.564).

CONCLUSIONS

The agreement between the investigated instruments was satisfactory, and both instruments also exhibited satisfactory discrimination of mortality; for that purpose, the best cutoff point was 16 nursing hours/patient day.

Factors affecting intensive care units nursing workload

Background:

The nursing workload has a close and strong association with the quality of services provided for the patients. Therefore, paying careful attention to the factors affecting nursing workload, especially those working in the intensive care units (ICUs), is very important.

Objectives:

This study aimed to determine the factors affecting nursing workload in the ICUs of the hospitals affiliated to Tehran University of Medical Sciences.

Materials and Methods:

This was a cross-sectional and analytical-descriptive study that has done in Iran. All nurses (n = 400) who was working in the ICUs of the hospitals affiliated to Tehran University of Medical Sciences in 2014 were selected and studied using census method. The required data were collected using a researcher–made questionnaire which its validity and reliability were confirmed through getting the opinions of experts and using composite reliability and internal consistency (α = 0.89). The collected data were analyzed through exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and using SPSS 18.0 and AMOS 18.0.

Results:

Twenty-five factors were divided into three major categories through EFA, including structure, process, and activity. The following factors among the structure, process and activity components had the greatest importance: lack of clear responsibilities and authorities and performing unnecessary tasks (by a coefficient of 0.709), mismatch between the capacity of wards and the number of patients (by a coefficient of 0.639), and helping the students and newly employed staff (by a coefficient of 0.589).

Conclusions:

The nursing workload is influenced by many factors. The clear responsibilities and authorities of nurses, patients' admission according to the capacity of wards, use of the new technologies and equipment, and providing basic training for new nurses can decrease the workload of nurses.

Nursing Activities Score and workload in the intensive care unit of a university hospital

OBJECTIVE

The nursing workload consists of the time spent by the nursing staff to perform the activities for which they are responsible, whether directly or indirectly related to patient care. The aim of this study was to evaluate the nursing workload in an adult intensive care unit at a university hospital using the Nursing Activities Score (NAS) instrument.

METHODS

A longitudinal, prospective study that involved the patients admitted to the intensive care unit of a university hospital between March and December 2008. The data were collected daily to calculate the NAS, the Acute Physiology and Chronic Health Evaluation (APACHE II), the Sequential Organ Failure Assessment (SOFA) and the Therapeutic Intervention Scoring System (TISS-28) of patients until they left the adult intensive care unit or after 90 days of hospitalization. The level of significance was set at 5%.

RESULTS

In total, 437 patients were evaluated, which resulted in an NAS of 74.4%. The type of admission, length of stay in the intensive care unit and the patients' condition when leaving the intensive care unit and hospital were variables associated with differences in the nursing workload. There was a moderate correlation between the mean NAS and APACHE II severity score (r=0.329), the mean organic dysfunction SOFA score (r=0.506) and the mean TISS-28 score (r=0.600).

CONCLUSION

We observed a high nursing workload in this study. These results can assist in planning the size of the staff required. The workload was influenced by clinical characteristics, including an increased workload required for emergency surgical patients and patients who died.
