Associations between unit workloads and outcomes of first extubation attempts in extremely premature infants below a gestational age of 26 weeks.

Objective: The objective was to explore whether high workloads in neonatal intensive care units were associated with short-term respiratory outcomes of extremely premature (EP) infants born <26 weeks of gestational age. Methods: This was a population-based study using data from the Norwegian Neonatal Network supplemented by data extracted from the medical records of EP infants <26 weeks GA born from 2013 to 2018. To describe the unit workloads, measurements of daily patient volume and unit acuity at each NICU were used. The effect of weekend and summer holiday was also explored. Results: We analyzed 316 first planned extubation attempts. There were no associations between unit workloads and the duration of mechanical ventilation until each infant's first extubation or the outcomes of these attempts. Additionally, there were no weekend or summer holiday effects on the outcomes explored. Workloads did not affect the causes of reintubation for infants who failed their first extubation attempt. Conclusion: Our finding that there was no association between the organizational factors explored and short-term respiratory outcomes can be interpreted as indicating resilience in Norwegian neonatal intensive care units.

Predictors of extubation success: a population-based study of neonates below a gestational age of 26 weeks.

OBJECTIVE: The aim of the study was to investigate first extubation attempts among extremely premature (EP) infants and to explore factors that may increase the quality of clinical judgement of extubation readiness. DESIGN AND METHOD: A population-based study was conducted to explore first extubation attempts for EP infants born before a gestational age (GA) of 26 weeks in Norway between 1 January 2013 and 31 December 2018. Eligible infants were identified via the Norwegian Neonatal Network database. The primary outcome was successful extubation, defined as no reintubation within 72 hours after extubation. RESULTS: Among 482 eligible infants, 316 first extubation attempts were identified. Overall, 173 (55%) infants were successfully extubated, whereas the first attempt failed in 143 (45%) infants. A total of 261 (83%) infants were extubated from conventional ventilation (CV), and 55 (17%) infants were extubated from high-frequency oscillatory ventilation (HFOV). In extubation from CV, pre-extubation fraction of inspired oxygen (FiO2) ≤0.35, higher Apgar score, higher GA, female sex and higher postnatal age were important predictors of successful extubation. In extubation from HFOV, a pre-extubation FiO2 level ≤0.35 was a relevant predictor of successful extubation. CONCLUSIONS: The correct timing of extubation in EP infants is important. In this national cohort, 55% of the first extubation attempts were successful. Our results suggest that additional emphasis on oxygen requirement, sex and general condition at birth may further increase extubation success when clinicians are about to extubate EP infants for the first time.

Integrating simulation training during clinical practice in nursing homes: an experimental study of nursing students' knowledge acquisition, self-efficacy and learning needs.

BACKGROUND: Limited access to supervision, feedback and quality learning experiences pose challenges to learning in the clinical setting for first-year nursing students who are beginning their clinical experiences. Prior studies have indicated that simulation training, as a partial replacement of clinical practice hours, may improve learning. However, there has been little research on simulation training integrated as a partial replacement during first-year students' clinical practice in nursing homes. The primary aim of this study was to examine first-year nursing students' knowledge acquisition and self-efficacy in integrating a partial replacement of clinical hours in nursing homes with simulation training. Its secondary aim was to examine perceptions of how learning needs were met in the simulated environment compared with the clinical environment. DESIGN: The primary aim was addressed using an experimental design that included pre- and post-tests. The secondary aim was investigated using a descriptive survey-based comparison. METHODS: First-year students at a Norwegian university college (n = 116) were asked to participate. Those who agreed (n = 103) were randomly assigned to the intervention group (n = 52) or the control group (n = 51). A knowledge test, the General Self-efficacy Scale and the Clinical Learning Environment Comparison Survey were used to measure students' outcomes and perceptions. The data were analysed using independent samples t-tests, chi-square tests and paired samples t-tests. RESULTS: Knowledge scores from pre- to post-tests were significantly higher in the intervention group than in the control group with a medium to large effect size (p < 0.01, Hedges' g = 0.6). No significant differences in self-efficacy were identified. Significant differences (p <  0.05) were observed between the simulated and the clinical environment with regard to meeting learning needs; effect sizes ranged from small and medium to large (Cohen's d from 0.3 to 1.0). CONCLUSION: Integrating the partial replacement of clinical hours in nursing homes with simulation training for first-year nursing students was positively associated with knowledge acquisition and meeting learning needs. These findings are promising with regard to simulation as a viable partial replacement for traditional clinical practice in nursing homes to improve learning.

Duration of Mechanical Ventilation and Extubation Success among Extremely Premature Infants.

OBJECTIVE: The objective of this study was to examine the duration of mechanical ventilation (MV) in days until the first successful extubation and the cumulative duration of MV until discharge of infants with gestational age (GA) <26 weeks. We also aimed to explore associations between early clinical variables and the cumulative duration of MV. DESIGN AND SETTING: This population-based study analysed data reported to the Norwegian Neonatal Network on extremely premature infants admitted between January 1, 2013, and December 31, 2018. RESULTS: A total of 406 infants were included, of which 293 (72%) survived to discharge. The proportion successfully extubated on their first attempt was 34% of the infants born at GA 22-23 weeks, 50% at GA 24 weeks, and 70% at GA 25 weeks. Median postmenstrual age (PMA) at the first successful extubation was 27 weeks. The median duration of MV was 35, 24, and 12 days for infants born at GA 22-23, 24, and 25 weeks, respectively. Male sex and low 5-min Apgar score were independent early predictors for prolonged MV duration adjusted for GA in regression analyses. CONCLUSIONS: Most of the infants born at GA 25 weeks were successfully extubated on the first attempt. However, half of the infants born <26 weeks experienced unsuccessful extubations, indicating a lack of useful clinical predictors of successful extubation. The median duration of MV in survivors was 4 weeks longer for infants at GA 22-23 weeks than for infants born at GA 25 weeks, while the difference in median PMA at the first successful extubation was 2 weeks.

Psychometric properties of the Norwegian version of the clinical learning environment comparison survey.

AIM: To translate The Clinical Learning Environment Comparison Survey (CLECS) into Norwegian and to evaluate the psychometric properties of the Norwegian version. DESIGN: A cross-sectional survey including a longitudinal component. METHODS: The CLECS was translated into Norwegian following the World Health Organization guidelines, including forward translation, expert panel, back-translation, pre-testing and cognitive interviewing. Nursing students at a Norwegian university college were invited to participate in the study (psychometrical testing) based on informed consent. Reliability and validity of the translated version of CLECS were investigated using a confirmatory factor analysis (CFA), Cronbach's alpha and test-retest analysis. RESULTS: A total of 122 nursing students completed the questionnaire and Cronbach alphas for the CLECS subscales ranged from 0.69 to 0.89. CFA goodness-of-fit indices (χ2 /df = 1.409, CFI = 0.915, RMSEA = 0.058) showed acceptable model fit. Test-retest ICC ranged from 0.55 to 0.75, except for two subscales with values below 0.5.

Supplementing Clinical Practice in Nursing Homes With Simulation Training: A Qualitative Study of Nursing Students' Experiences.

INTRODUCTION: Limited access to nurse supervisors, insufficient learning support and staff with high workloads are well documented in the research literature as barriers to nursing students´ learning in clinical practice in nursing homes. Due to these barriers nursing students may benefit from additional learning support from nurse educators during their clinical practice period. OBJECTIVE: The study aimed to explore nursing students' experiences of supplementary simulation training as a tool to support learning during clinical practice in nursing homes. METHODS: A descriptive qualitative design was used. Twenty-seven first-year nursing students from a university college in Norway were interviewed after attending a seven-week practice period in nursing homes with supplementary simulation training. Three semi-structured focus group interviews were audio recorded, transcribed, and analysed using systematic text condensation. FINDINGS: Three categories of student experiences were identified: enhancing the reasoning behind care, transferring knowledge and experiences between the learning environments and enhancing the sense of mastery. CONCLUSION: The supplementary simulation training seemed to complement clinical practice by consolidating the students' learning during the clinical practice period, enhance the students' motivation and sense of mastery, and consequently their efforts to seek out new challenges, explore and learn both in the clinical and the simulated environment.

Elements in scenario-based simulation associated with nursing students' self-confidence and satisfaction: A cross-sectional study.

Aim: To identify elements in scenario-based simulation associated with nursing students' satisfaction with the simulation activity and self-confidence in managing the simulated patient situation. The study will provide insight to improve the use of simulation as a learning strategy. Design: A cross-sectional study. Method: The Student Satisfaction and Self-Confidence in Learning scale was used as the outcome measure to identify associations with elements of the Simulation Design Scale and the Educational Practices Questionnaire scale after scenario-based simulation using patient simulators. First-year nursing students at a university college in Norway (N = 202) were invited to participate and (N = 187) responded to the questionnaires. Results: The mean scores for self-confidence and satisfaction were 4.16 and 4.57, respectively. In the final multiple linear regression analysis, active learning was associated with satisfaction with the simulation activity, while clear objectives and active learning were associated with self-confidence in managing the simulated patient situation.

Prevalence of pressure ulcer and associated risk factors in middle- and older-aged medical inpatients in Norway.

AIMS AND OBJECTIVES: To describe the prevalence of pressure ulcers among middle- and older-aged patients in a general medical hospital in Norway and to describe the associations between pressure ulcers and potential risk factors additional to the Braden risk score. BACKGROUND: Degrees of mobility, activity, perfusion and skin status are risk factors for development of pressure ulcer. Nurses' clinical judgements combined with risk assessment tools are effective to detect pressure ulcer risk. DESIGN: Cross-sectional study. METHODS: The study was performed as part of a research project conducted between September 2012-May 2014 in a general hospital in the capital of Norway. Registered nurses and nursing students collected data from all eligible patients on 10 days during the students' clinical practice studies. The Braden scale was used to measure pressure ulcer risk, and skin examinations were performed to classify the skin area as normal or as indicative of pressure ulcer according to the definitions by the National Pressure Ulcer Advisory Panel. Comorbidities were collected by patient's self-report. This analysis focused on the 255 inpatients at the medical wards ≥52 years of age, most of whom had more than one comorbidity. RESULTS: The prevalence of pressure ulcers was 14.9% in this sample. Higher age, underweight, diabetes and worse Braden scores were factors associated with pressure ulcer, and pressure ulcer was most frequently sited at the sacrum or heel. CONCLUSION: Adding age, weight and diabetes status to pressure ulcer risk assessment scales may improve identification of patients at risk for pressure ulcers. RELEVANCE TO CLINICAL PRACTICE: Knowledge about strengths and limitations of risk assessment tools is important for clinical practice. Age, weight and diabetes status should be considered for inclusion in risk assessment tools for pressure ulcers in medical wards.

Nurses' reports of staffing adequacy and surgical site infections: A cross-sectional multi-centre study.

BACKGROUND: It is indicated that healthcare personnel's perceptions of the work environment may reflect the clinical outcomes for the patients they care for. However, the body of evidence is inconsistent when it comes to the association between work environment and surgical site infection. OBJECTIVES: The aim of this study is to examine the associations between nurse-reported characteristics of the work environment and incidence of surgical site infections after total hip arthroplasty. DESIGN AND SETTINGS: This is a cross-sectional multicentre study conducted in 16 Norwegian hospitals. PARTICIPANTS: Clinical outcomes for 2885 patients >18years that underwent total hip arthroplasty are combined with work environment descriptions from 320 nurses. MATERIALS AND METHODS: We combine data about surgical site infections from The Norwegian Surveillance System for Antibiotic Consumption and Healthcare-Associated Infections and hospital characteristics such as overall survival probability (from administrative patient data) and nurses' reports of characteristics of the work environment (from a multicentre survey among nurses in Norwegian hospitals). Stepwise mixed-effects logistic regression model was performed to examine the associations between characteristics of the work environment and surgical site infections. RESULTS: The incidence of surgical site infection among 2885 patients undergoing total hip arthroplasty in 16 Norwegian hospitals was 2.6%. Older age, elective procedures and high scores for staffing adequacy were associated with risk for surgical site infection. The association between high scores for adequate staffing and low risk for surgical site infections was present for patients that were admitted for an elective procedure, but not for patients admitted for a non-elective procedure. CONCLUSION: Our results show that the risk of surgical site infections after elective total hip arthroplasty was lower in hospitals where nurses assessed staffing as adequate. Our findings add to the existing literature that examines the linkage between work environment and clinical outcomes.

Organization of nursing care in three Nordic countries: relationships between nurses' workload, level of involvement in direct patient care, job satisfaction, and intention to leave.

BACKGROUND: Health care systems in Finland, Norway and Sweden share many similarities, e.g. full-coverage and tax-financed, with predominately public sector hospitals. Despite similarities, there are differences in the working situations for RNs within these Nordic countries. The aim of this study was to analyze associations between RNs' patient workload and level of involvement in direct patient care, their job satisfaction and intention to leave in these countries. METHODS: A workforce survey was conducted through RN4CAST, an EU 7th framework project. The survey included 118 items derived from validated instruments or tested in prior research. Responses from 1133 RNs at 32 Finnish hospitals, 3752 RNs at 35 Norwegian hospitals, and 11 015 RNs at 71 Swedish hospitals comprise the database, which was analyzed using logistic and odds ratio regressions analyses. RESULTS: We found statistically significant differences in RNs' level of involvement in direct patient care (p < 0.001, Sweden compared to Norway and Finland), in patient workload and in number of patients needing ADL assistance and surveillance. A U-formed relationship was found between level of involvement in direct patient care and intention to leave in Sweden, and more satisfaction among RNs in roles with more direct patient care (OR = 1.16, 1.02 ≤ CI95% ≤ 1.32). Nearly half the Finnish sample report intention to leave, with significantly lower levels in Norway and Sweden (p < 0.001). Patient workload is associated with job satisfaction and intention to leave to some degree in all countries, i.e. greater patient workload, less job satisfaction and greater intention to leave. CONCLUSIONS: This study suggests that more attention paid to patient mix, workload and role of RNs in patient care might potentially diminish intention to leave and increase job satisfaction in these Nordic countries.

An observational study: associations between nurse-reported hospital characteristics and estimated 30-day survival probabilities.

BACKGROUND: There is a growing body of evidence for associations between the work environment and patient outcomes. A good work environment may maximise healthcare workers' efforts to avoid failures and to facilitate quality care that is focused on patient safety. Several studies use nurse-reported quality measures, but it is uncertain whether these outcomes are correlated with clinical outcomes. The aim of this study was to determine the correlations between hospital-aggregated, nurse-assessed quality and safety, and estimated probabilities for 30-day survival in and out of hospital. METHODS: In a multicentre study involving almost all Norwegian hospitals with more than 85 beds (sample size=30, information about nurses' perceptions of organisational characteristics were collected. Subscales from this survey were used to describe properties of the organisations: quality system, patient safety management, nurse-physician relationship, staffing adequacy, quality of nursing and patient safety. The average scores for these organisational characteristics were aggregated to hospital level, and merged with estimated probabilities for 30-day survival in and out of hospital (survival probabilities) from a national database. In this observational, ecological study, the relationships between the organisational characteristics (independent variables) and clinical outcomes (survival probabilities) were examined. RESULTS: Survival probabilities were correlated with nurse-assessed quality of nursing. Furthermore, the subjective perception of staffing adequacy was correlated with overall survival. CONCLUSIONS: This study showed that perceived staffing adequacy and nurses' assessments of quality of nursing were correlated with survival probabilities. It is suggested that the way nurses characterise the microsystems they belong to, also reflects the general performance of hospitals.

A cross-sectional study to identify organisational processes associated with nurse-reported quality and patient safety.

OBJECTIVES: The purpose of this study was to identify organisational processes and structures that are associated with nurse-reported patient safety and quality of nursing. DESIGN: This is an observational cross-sectional study using survey methods. SETTING: Respondents from 31 Norwegian hospitals with more than 85 beds were included in the survey. PARTICIPANTS: All registered nurses working in direct patient care in a position of 20% or more were invited to answer the survey. In this study, 3618 nurses from surgical and medical wards responded (response rate 58.9). Nurses' practice environment was defined as organisational processes and measured by the Nursing Work Index Revised and items from Hospital Survey on Patient Safety Culture. OUTCOME MEASURES: Nurses' assessments of patient safety, quality of nursing, confidence in how their patients manage after discharge and frequency of adverse events were used as outcome measures. RESULTS: Quality system, nurse-physician relation, patient safety management and staff adequacy were process measures associated with nurse-reported work-related and patient-related outcomes, but we found no associations with nurse participation, education and career and ward leadership. Most organisational structures were non-significant in the multilevel model except for nurses' affiliations to medical department and hospital type. CONCLUSIONS: Organisational structures may have minor impact on how nurses perceive work-related and patient-related outcomes, but the findings in this study indicate that there is a considerable potential to address organisational design in improvement of patient safety and quality of care.
