The environment of health organizations can determine healthcare quality and patient safety. Longer working hours can be associated with nurses’ health status and care quality, as well as work-related hazards. However, little is known about the association of hospital nurses’ working hours and patient safety competencies with adverse nurse outcomes. In this cross-sectional descriptive study, convenience sampling was employed to recruit 380 nurses from three tertiary care hospitals in South Korea. Data were collected using structured questionnaires from May to June 2016. Hierarchical linear regression analysis was used to identify the association of working hours and patient competencies with adverse nurse outcomes among 364 participants selected for analysis. Most nurses worked over 40 h/week. Working hours (β = 0.202, p < 0.001) had the strongest association with adverse nurse outcomes. Low perceived patient safety competencies (β = −0.179, p = 0.001) and frequently reporting patient safety accidents (β = 0.146, p = 0.018) were also correlated with adverse nurse outcomes. Nursing leaders should encourage work cultures where working overtime is discouraged and patient safety competencies are prioritized. Further, healthcare managers must formulate policies that secure nurses’ rights. The potential association of overtime with nurse and patient outcomes needs further exploration.

This study aimed to explore turnover rates for Korean acute care hospital nurses and identify factors influencing their turnover. The study was retrospective in nature. Nurse cohort data were obtained from hospital status data from Korea's Health Insurance Review Assessment Service. The observation period was from January 1, 2012 to December 31, 2016, and data for 96,158 nurses were analyzed. Independent variables included nurses' age and sex and hospital setting, type, ownership, and nurse staffing level. Kaplan-Meier analysis was performed to estimate survival curves, and factors influencing turnover were analyzed using Cox's proportional hazard regression. The cumulative turnover probability for all nurses was .17, .29, .38, .45, and .50 for the first, second, third, fourth, and fifth years, respectively. The results showed that the longer the career duration, the lower the turnover rates. According to the factors influencing nurse turnover, both nurses' (i.e., sex and career duration) and hospitals' (i.e., hospital setting, type, ownership, and nurse staffing level) characteristics were statistically significant. It should be noted that the turnover rate of nurses with less than three year of career duration and of those with less than one year has been shown to be quite high. Therefore, target populations for acute care hospital nurse turnover should be expanded from new graduate nurses to experienced nurses with less than 3 years of career. Further studies are required to examine the causes of high turnover rates in hospitals that are small and/or have low nurse staffing levels.

Aim: This study aimed to calculate the total daily nursing workload and the optimal number of nurses per general unit based on the nursing intensity.Design: This study was conducted using a cross‐sectional study.Methods: Three units at one general hospital were investigated. Patient classification according to nursing needs was performed for over 10 days in each unit in September 2018. The direct and non‐direct nursing time and nursing intensity scores were analysed using descriptive statistics.Results: For the internal medicine unit, the average direct nursing time per patient was 1.0, 1.5, 2.2 and 2.9 h for Groups 1, 2, 3 and 4, respectively. For the surgical unit, the average direct nursing time per patient was 0.9, 1.4, 2.1 and 2.6 h for Groups 1, 2, 3 and 4, respectively. 5 and 9 additional nurses were needed in the internal medicine and surgical nursing units.Patient Contribution: This study confirmed that the optimal number of nurses was not achieved and that the nursing intensity was very high. Long‐term efforts, such as improving the nursing environment, should be made to ensure an optimal number of nurses in various nursing units.

DCE was applied to investigate nursing students’ preferred hospital choice criteria and to investigate the trends in the trade-offs by calculating the marginal rate of substitution between these criteria. This study identified the properties of the hospitals primarily selected by nursing students, and aims to estimate the monetary value of each attribute. Based on discussions and in-depth interviews with nursing students’ focus groups and a literature review, we created a discrete choice experiment (DCE) that assessed how students’ stated preference for a certain hospital choice was influenced by various job attributes: higher salary, location, hospital type, salary per year, provision of a dormitory, etc. We applied this DCE to nursing students in South Korea using a brief structured questionnaire, and we used conditional logit models to estimate the utility of each job’s attributes. Willingness to pay (WTP) was estimated as the ratio of the value of the coefficient of interest to the negative of the cost attribute. Complete data for the DCE analysis were available for 702 nursing students. In the main effect mixed logit model, the welfare system and organizational culture were most strongly associated with job preference. Location, hospital type, and opportunity to upgrade qualifications had a negative influence on hospital choice. The WTP threshold was 7,043,000 KRW for the welfare system and 9,928,000 KRW for the organizational culture (relation-oriented). Better nursing working conditions, such as a positive organizational culture and the provision of a welfare system, can improve the motivation and applications for hospitals in rural areas.
