Abstract

Objectives: This study was to examine the features of work and posture analysis outputs in assessment of exposure to musculoskeletal disorder (MSD) risk factors in general hospital nurses.
Methods: Work and posture analyses were carried out using observational approaches for nurses at general hospitals across Korea. With development of a taxonomy for assessing exposure to MSD risk factors, nursing tasks were documented in frequency (%time) for 8 hours a day in work analyses. Rapid Entire Body Assessment (REBA) scores were obtained for mode and maximum risk levels , respectively, during posture analyses.
Results: A total of 27 nurses were observed while conducting 7 nursing tasks at 6 general hospitals. For both the work analyses and posture analyses, the taxonomy was developed and used. In the work analyses, ‘Video display terminal task’ and ‘Nursing examination/ treatment’ were the highest as 25%time for 8 hours a day, followed by ‘Patient care’ and ‘Room rounding’ as 13%time in order . In the posture analyses, the mode REBA scores were 2 or less for all nursing tasks while the maximum REBA scores were 7 for upper limbs at ‘Room rounding’ and 6 for trunk/neck/legs at ‘Patient care’.
Conclusions: The results showed the study nurses are occasionally at a risk for MSD, a medium level as designated in the REBA risk level, suggesting that it is important to control awkward posture at the nursing tasks such as ‘Room rounding’ and ‘Patient care’, in priority, for preventing MSD in the hospital sector including the study general hospitals.
