Introduction

Emergency medical staff who are at the forefront of health care delivery face many occupational stresses that have psychological, physical, behavioral, and organizational consequences for them, including musculoskeletal disorders. The purpose of this study was to investigate the correlation between musculoskeletal injuries and stress load tolerance among medical emergency staffs in Hamedan province.


 

Materials and Methods

In this descriptive-correlational study, conducted in 2019, 76 (40%) of urban and 114 (60%) of employees of road bases were selected from among emergency medical staff of Hamadan, Iran. Data were collected using Nordic Musculoskeletal Injury Questionnaire and Occupational Stress Questionnaire. Data were analyzed by SPSS 23 (SPSS Inc., Chicago, Ill., USA) using descriptive statistics, t-test and Spearman correlation coefficient.

 

Results


The mean age of the participants was 34.05 (± 8.11) years and the work experience was 123.42 (±84.22) months. The majority (77%) were married, 57.3% had undergraduate degrees and 46.9% had formal employment. Employee stress burden was 503.3 (161.23%) out of 1050 points. Persons who had musculoskeletal disorder due to their job had reported more stress than others; hoever, this difference was not significant (P<0.05). People with musculoskeletal disorders in neck reported higher stress load (P<0.05) than others which was not significant. There was a significant relationship between type of employment, work experience, and type of exercise with musculoskeletal disorders (P<0.05).

Discussion


Based on the obtained results, the staff stress load was 503.03 (±161.23) out of 1050 possible scores. Due to the use of different tools to measure the job stress of medical staff, including emergency personnel, comparing the prevalence of stress obtained in different studies is limited. In the obtained results, the highest average reported stress of employees in the amount and severity of stress was related to environmental and occupational conditions. In the present study, the level of job stress of employees was at the average score level. The results of the present study were consistent with the results of the study of Moshtagh et al. [8].
In the continuation of the results of this study, all employees who were associated with musculoskeletal disorders due to their jobs, expressed some more stress than others, but this difference was not significant (P <0.05). Only people with musculoskeletal disorders in the neck had a higher stress load than others (P <0.05).
The results of the present study on the relationship between work history with musculoskeletal disorders were consistent with the study of Davis and Kotowski, who examined the prevalence of musculoskeletal disorders in nurses of hospitals, long-term care centers and home health care. In this study, it was stated that with increasing work experience, the probability of musculoskeletal disorders has increased. Although the target group is different in the above study and the present study, it seems that with increasing working years and decreased physical strength, the probability of musculoskeletal disorders is higher [35].


 

Conclusion

 There was a significant relationship only between stress and musculoskeletal damage. By modifying and eliminating stressors in emergency personnel’s routines, by holding workshops on ergonomic principles as well as stress reduction principles, it is possible to reduce the physical disorders of emergency personnel.
