[Mental Workload Assessment of Health Care Staff by NASA-TLX].

The National Aeronautics Space Administration Task Load Index (NASA-TLX) is the most frequently used mental workload assessment method. This article reviews 26 papers which report mental workload evaluation in health care staff, categorizing them into laparoscopic surgery, anesthesia, ICU, electronic record, patient controlled analgesia, emergency, display and others. Although indices other than NASA-TLX were also used in these papers, this review describes the results of NASA-TLX only.
