Magnitude and associated factors of low back pain among nurses working at intensive care unit of public hospitals in Amhara region, Ethiopia

Background Low back pain is a common public health problem throughout the world with a global prevalence from 28% to 86%. Nurses working in intensive care units are handling people who are critically ill and helpless, which requires more assistance for transferring and handling activities. This possesses a risk for low back pain but little is known about it in Ethiopia. This study aimed to assess the magnitude of low back pain and associated factors among nurses who work at intensive care units in Amhara region public hospitals, North Ethiopia. Methods A multi-centered institution-based cross-sectional study was conducted at Amhara region public hospitals from March 1-30, 2020. A simple random sampling technique after proportional allocation was used to select the study participants. Data were collected using a standard modified Nordic musculoskeletal assessment tool. After data were checked for completeness and consistency, it was entered into Epidata version 3.1 and exported to Statistical Package for Social Science software version 26 for analysis. Descriptive statistics were computed. A binary logistic regression model was used to identify factors associated with low back pain. Finally, those variables with a p-value of <0.05 in multivariable analysis were considered statistically significant. Result Study was conducted among 412 intensive care unit nurses giving a response rate of 97.6%. The magnitude of low back pain was 313 (76%) [95% CI: (71.6%-79.9%)]. Being female [AOR = 2.674 (1.404, 5.076)], unavailability of assistive device for patient handling [AOR = 2.139 (1.035, 4.410)], lack of training on intensive care [AOR = 2.017 (1.092, 3.943)], lack of regular exercise [AOR = 2.164 (1.164, 4.108)] and job stress [AOR = 3.66 (1.955, 6.498)] were factors significantly associated with low back pain. Conclusions In this study the magnitude of low back pain was high. Being female, unavailability of an assistive device for patient handling, lack of training on intensive care, lack of regular exercise and job stress were factors associated with low back pain. Policymakers and concerned bodies should emphasize the accessibility of assistive devices for patient care, provision of training on intensive care, and adaptive working environment for intensive care unit nurses.
