Abstract
BackgroundIntensive care unit (ICU) nurses are at high risk for work-related musculoskeletal disorders (WRMDs). Data on occupational injuries indicate the significance of WRMDs among ICU nurses. Intervention programs have previously been developed to reduce WRMDs, but different intervention methods need to be adopted for different groups of people. This study aimed to evaluate the effectiveness of a multidimensional intervention program to prevent and reduce WRMDs in ICU nurses.MethodsThis study was designed as a two-armed cluster-controlled trial with an intervention group and a control group. The clusters were independent hospital ICUs, and the participants consisted of registered nurses in China. By cluster random sampling, 89 nurses from two ICUs were assigned to the intervention group, and 101 nurses from two other ICUs were assigned to the control group. A multidimensional intervention program based on previous studies was designed. This program combined improving risk perception, health behavior training, and promoting a safe working environment. The multidimensional intervention program was implemented in the intervention group, whereas routine specialist training was implemented in the control group. Baseline and follow-up (3 and 6 months) data were collected using self-reported online questionnaires. The primary outcome was the report rate of WRMDs in the past 7 days. Secondary outcomes were risk perception, application of health behavior, and perception of a safe working environment. The data were statistically analyzed using SPSS 19.0.ResultsA total of 190 nurses provided three recorded outcome measurements (intervention group, N = 89 (94.68%); control group, N = 101 (94.39%)). After 6 months, the intervention group experienced significant improvement relative to the control group in the report rate of WRMDs in the past 7 days (OR = 1.953, p = 0.037), risk perception (OR = 0.517, p < 0.001), application of health behavior (OR = 0.025, p < 0.001), and perception of a safe working environment (OR = 1.637, p = 0.024).ConclusionThe multidimensional intervention program was superior to routine specialist training in preventing the occurrence of WRMDs in ICU nurses. WRMD training should include multifaceted approaches and pay increased attention to specific department functions.

Study design This study was designed as a two-armed clustercontrolled trial with an intervention group and a control group, where the clusters were independent hospital ICUs in China, and the participants consisted of registered nurses in clinical practice
From two ICUs, 94 nurses were assigned to the intervention group, and from the two remaining ICUs, 104 nurses were assigned to the control group by cluster random sampling
Summary
Intensive care unit (ICU) nurses are at high risk for work-related musculoskeletal disorders (WRMDs). Data on occupational injuries indicate the significance of WRMDs among ICU nurses. This study aimed to evaluate the effectiveness of a multidimensional intervention program to prevent and reduce WRMDs in ICU nurses. Work-related musculoskeletal disorders (WRMDs) are injuries to the musculoskeletal system that result from exposure to the work environment [1]. The 12-month prevalence of WRMDs among nurses worldwide ranges from 40 to 85%; the difference is attributed to variations in the national culture, medical environment, and nature of the job [2,3,4,5]. In China, a large number of nurses often work with disorders because of a shortage of nursing staff and a lack of awareness of the cumulative damage of WRMDs [8]. In a survey of WRMDs among Chinese nurses, the 12-month prevalence of WRMDs was 77.43%, but only 9.39% of nurses took a sick leave due to WRMDs [9]
