Datamining techniques - decision tree: new view on nurses' intention to leave

Abstract

Aim: The aim of the survey is to identify factors of the work environment which are important for general nurses when they are considering whether or not to leave their current employer. Design: The research consists of an observational and a crosssectional study. Methods: Based on a modified interpretation of Herzberg's theory, we created a structured interview to investigate environmental factors. Interviewers carried out 1,992 interviews with hospital nurses working in the Czech Republic, between 2011 and 2012. The data gathered were analyzed with data mining toolsa decision tree and nonparametric tests. Results: If a good opportunity arose, 34.7% of nurses would leave their current employer. The analysis of the decision tree identified the factor "Patient care", i.e. a factor concerning the nature of the work itself, as the most important. Data mining offers a new view of the data and can reveal valuable information existing within the primary data. Conclusion: Data mining has great potential in nursing. In this research, the decision tree shows that the essence of the nursing profession is the nursing work itself and it is also the most significant stabilizing factor. The management of healthcare providers should create and maintain a work environment which will ensure nursing work can be performed without impediment, thus minimizing staff turnover.

The Impact of the Coronavirus Disease (COVID-19) Pandemic on Nurses’ Turnover Intention: An Integrative Review

“…In addition, while recognition was associated with lower nurses’ turnover intention [ 3 , 24 , 33 ], workplace bullying was associated with higher nurses’ turnover intention [ 7 , 28 ]. Vévoda, Vévodová, Bubeníková, Kisvetrová, and Ivanová; and Wubetie et al found that salary is associated with nurses’ turnover intention [ 2 , 44 ]. Furthermore, leadership and supervision support were significantly associated with turnover intention [ 34 , 40 , 47 ].…”

“…Nurse turnover has been defined as a global healthcare-system issue [ 1 ]. It has been defended as voluntary and early termination of nurses’ employment [ 2 ]. Nurse turnover could be either organizational or professional, with the latter being the most consequential because of its contribution to the preexisting nurse shortage [ 3 ].…”

Analysis of the Impact of Selected Physical Environmental Factors on the Health of Employees: Creating a Classification Model Using a Decision Tree

“…Dangare and Apte [24] use various data-mining techniques such as decision trees, Naïve Bayes, as well as neural networks to analyze heart disease. Vévoda et al [25] monitored factors in the working environment influencing the decisions of nurses to stay with or leave their employer. The collected data from the questionnaires were analyzed using data-mining tools, decision trees, and non-parametric tests.…”

Ensuring a sufficient number of personnel as part of the safety culture in medical facilities

“…Otevřená kultura, ve které mohou být nedostatky, chyby a nežádoucí události diskutovány, může pomoci snížit výskyt pochybení. Jak ukazují některé průzkumy [5,7,20], množství práce při nedostatku kvalifikovaného personálu přispívá ke stresovosti a promítá se na pracovním výkonu.…”
