Abstract
BACKGROUND: Work-related musculoskeletal disorder (WMSD) is a collective and descriptive term used for the symptoms caused or aggravated by work. Significant WMSDs can affect the productivity and Quality of Life (QOL) of nurses. This study was undertaken to estimate the prevalence of WMSDs, identify their risk factors, and find the association, if any. This study also assessed the quality of life of nurses and its association with WMSDs. METHODS: This cross-sectional study was conducted among 207 staff nurses at a tertiary care hospital in Bangalore for a period of 7 months (June-2018 to Dec-2018). The nurses were stratified based on their parent department into three broad categories - Medical, Surgical, and Operation Theatre. Stratified random sampling was followed to obtain the required number of nurses from each stratum. Data was collected using a pre-tested semi-structured questionnaire, Nordic Musculoskeletal Questionnaire (NMQ), clinical examination tests, and WHOQOL-BREF. RESULTS: The annual prevalence of WMSDs among the study subjects using NMQ was 168 (81.2%). The prevalence of WMSDs based on clinical examination tests was 67 (32.4%). Repetitive movements at work (OR 9.3, 95% CI 3.4-25.7), working in abnormal postures for prolonged periods (OR 4.7, 95% CI 1.7-12.9), and working even when sick (OR 5.3, 95% CI 2.0-14.1) were the risk factors for WMSDs (P < 0.05). No significant association was found between reported WMSDs (according to NMQ) and QOL. CONCLUSION: Our study found that the prevalence of WMSDs was high among the staff nurses and it did not affect their QOL significantly. Workshops and training sessions on ergonomics should be regularly conducted at the workplace to prevent WMSDs.
