Measuring workload of ICU nurses with a questionnaire survey: the NASA Task Load Index (TLX)
IIE Transactions on Healthcare Systems Engineering, 2011
High workload of nurses in Intensive Care Units (ICUs) has been identified as a major patient safety and worker stress problem. However, relative little attention has been dedicated to the measurement of workload in healthcare. The objectives of this study are to describe and examine several methods to measure workload of ICU nurses. We then focus on the measurement of ICU nurses' workload using a subjective rating instrument: the NASA TLX.
Assessment of Mental Workload in Nursing by Using Nasa- TLX
Journal of Urmia Nursing and Midwifery Faculty, 2014
80 percent of works in healthcare system conducted by nurses. Nursing is one of the high workload occupations. Assessments of work load in nurses who are concerned with human life are important, in order to provide effective service. The object of the current study was to determine mental work load among nurses and its effective factors. Materials & Methods: This study was a descriptive - analytic and cross-sectional one that was conducted among 120 nurses of Urmia University of Medical Sciences hospitals in 2013. In this study, we used NASA - Task load indexes (TLX) for assessment of mental workload of nurses. Data were analyzed by descriptive statistics and Pierson correlation analysis. Results: The Results showed that mental needs were maximum (86/16± 21/24) and physical needs were minimum (55/83± 22/16) compared to other workload aspects. Mean mental work load score in Intensive Care Unit (ICU) was maximum (82/33± 20/49). Between the hours of work per week, department, shift wor...

and simultaneously (dual task). The results of the ANOVAs performed showed that there are no differences with regard to the three instruments' intrusiveness, and that among the three subjective workload instruments WP has an outstanding sensitivity to the different task manipulations. To evaluate the diagnosticity of each of the three instruments canonical discriminant analysis was used, and this demonstrated that the three multidimensional ratings provided diagnostic information on the nature of tasks demands that was consistent with the a priori task characterisation. However, the diagnostic power of WP was clearly superior to that obtained using TLX or SWAT. Pearson correlations between each performance and each subjective workload measure were calculated to evaluate the concurrent validity of each instrument with task performance, and to assess the convergent validity of the instruments. The three coefficients were positive and near to one, showing the high convergent validity of the three instruments considered in this research. Implementation requirements and subject acceptability were also compared. Finally, practical implications on the three assessment approaches are mentioned.
Behavioral and Subjective Workload Metrics for Operational Environments
The assessment of crew performance capability under conditions of sustained intensive air operations requires the use of specialized measures of operator workload which are matched to the nature of the investigation and to the environment in which the workload evaluation must be conducted. In many cases, the effects of severe combined stressors and of aircrew performance requirements on mental workload cannot be studied in the laboratory, and must be addressed in high fidelity simulation or during operational test exercises. This paper examines the advantages and limitations of traditional subjective report and behavioral measures of workload for application in operational environments. In addition, recent efforts at the U.S. Air Force Aerospace Medical Research Laboratory to develop improved field-usable subjective and behavioral secondary task metrics are described.
NASA TLX: Software for assessing subjective mental workload
2009
Abstract The NASA Task Load Index (TLX) is a popular technique for measuring subjective mental workload. It relies on a multidimensional construct to derive an overall workload score based on a weighted average of ratings on six subscales: mental demand, physical demand, temporal demand, performance, effort, and frustration level. A program for implementing a computerized version of the NASA TLX is described. The software version assists in simplifying collection, postprocessing, and storage of raw data.

Detecting short periods of elevated workload: A comparison of nine workload assessment techniques
Journal of Experimental Psychology: Applied, 1996
The present experiment tested the merits of 9 common workload assessment techniques with relatively short periods of workload in a car-driving task. Twelve participants drove an instrumented car and performed a visually loading task and a mentally loading task for 10,30, and 60 s. The results show that 10-s periods of visual and mental workload can be measured successfully with subjective ratings and secondary task performance. With respect to longer loading periods (30 and 60 s), steering frequency was found to be sensitive to visual workload, and skin conductance response (SCR) was sensitive to mental workload. The results lead to preliminary guidelines that will help applied researchers to determine which techniques are best suited for assessing visual and mental workload.
Workload: a comparison between the online and observational methods

To measure nursing Workload (WL) of nurses who work in the Inpatient Unit, as recommended by the Nursing Interventions Classification (NIC), comparing observational and online methods to propose supervision strategies for academic professionals. Quantitative, descriptive, observational study performed in a Clinical/Surgical Hospital Unit. 30 direct and indirect activities. Data collected in observational and online records. Statistical analysis: SPSS 18.0 software, percentage frequencies and associated times between groups by Fisher's Exact test, 95% confidence interval, significance level 5%. Comparing the activities performed with the NIC time: from the direct 16, five observational and five online, were out of range, with no significant difference between frequencies (P=0.427). Of the 14 indirect, only in the observational, two were out of the range, without significant difference (P=0.486). Both methods measure WL; the online method developed accompanies activities performed...
Workload Measurement Models In Hospital: Literature Review
Journal Research of Social Science, Economics, and Management
Nurse workload is all activities, activities, actions taken by a nurse while the nurse is on duty in a hospital service unit. The purpose of this literature is to identify which method is more effective and efficient to measure the workload of nurses. Article review was carried out through several electronic databases including Google Scholar, Google Scholar, Pubmed with the keyword "nurse workload", inclusion criteria included articles published between 2015 and 2022, full text in both English and Indonesian. A literature search found 72 articles, then 51 articles were removed according to the exclusion criteria, so that only 8 articles were identified. The results of the literature study show that the WISN method is most often used to determine the workload of health workers, not only nurses. made by several people including Richa Noprianty et al, 2020 with the topic Analysis of Nurses Staff Needs Using Workload Indicate Staff Need in Pediatric Ward with Time Motion Stud...
