Abstract: Objective: To explore evidence-based prevention and management programs for pregnancy-related low back pain, and evaluate the application effects, so as to provide reference for pregnancy management. Methods: Evidence-based methods were used to build the evidence application strategy, and implemented in the Obstetrics Clinic of a tertiary grade A hospital in Henan province from December 2020 to June 2022. The indicators of patients before and after the application of evidence and the implementation rate of the reviewed entries were compared. Results: After the implementation of the evidence, there was no statistically significant difference in the incidence of pregnancy-related low back pain compared to before implementation (P>0.05). The pain degree of pregnant women with pregnancy-related low back pain from the third assessment was lower than that of the baseline review group, and the average pain degree was lower than that of the baseline review group at the four times after implementation (P<0.05). In terms of disability, the degree of disability after implementation from the second evaluation was lower than that of the baseline review group, and the average disability level after implementation was lower than that of the baseline review group (P<0.05). Conclusion: The evidence of pregnancy-related low back pain during pregnancy can guide nursing practice, help to reduce the degree of pregnancy-related low back pain and dysfunction index, and standardize pain management behavior.
