Ergonomic Risk Assessment In Clinical Laboratory Technicians

Abstract

Background -A clinical laboratory technician working under microscope requires static posture of the spine and upper extremity for long period of time. This makes them prone to develop musculoskeletal disorders. Occupations which require maintaining static postures for long hours put increase load or forces on the muscles and tendons which lead to fatigue and pain. Apart from reducing the workers’ quality of life and productivity, WMSDs are the most expensive form of work disability. Thus, the primary aim of the study was to assess Ergonomic risk in clinical laboratory technicians.
Method-. Study was done on 35 microbiologists working in Kasturba hospital, Mumbai and in some private clinics. A self-made questionnaire and RULA tool was used to assess the ergonomic risk factors.
Results-19 subjects have a RULA score of 3, 9 subjects have a RULA score of 4, 4 subjects have a RULA score of 5, 3 subjects have a RULA score of 6. None of the subjects have score between 1 &2 and score 7 and above (Graph.3).80% of the subjects lie in action level 2, 20% of the subjects lie in action level 3, none of them lie in action level 1 & 4.
Conclusion-Physical ergonomic risk is mild to moderate in clinical laboratory technicians, demanding early changes in posture and further investigation. Neck pain and forearm support during work were attributed as risk factors for increase in RULA score
