In the previous discussion post, the research article selected is Electroacupuncture for Postoperative Urinary Retention: A Systematic Review and Meta-Analysis (Zhong et al., 2018). First, what is post-operative urinary retention and its treatment? Post-operative urinary retention (POUR), the inability to void with a full bladder, is a common issue occurring in up to 30% of post-surgical cases undergoing abdominal surgery (U.S. National Library of Medicine, 2018). While this is usually self-resolving, POUR sometimes requires intervention using catheterization, medication or electroacupuncture (EA).

Next what limitations do the authors note? The sample for this study included only women, and the data was gathered from studies that were from China and had small sample sizes, and results show that the studies may have publication bias in the therapeutic effect of EA. Overall the quality of evidence-based on Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) for comparisons was very low to moderate; most studies were very low, limiting assurance in trial findings (Zhong et al., 2018, para.4).

What is the unit of analysis? Meta-analysis the systematic review and use of the original data from all included studies to create a new report. As a result, a meta-analysis can draw conclusions that are more meaningful than a systematic review. Again, a meta-analysis is more useful for inferring causation than any single study.

Asking questions about the research articles will allow the nurse to determine if the study is a legitimate one, who is supporting and paying for the study, how it will apply to the work and care of their patients. Will this research be able to assist in maintaining patient care practice with current evidence-based practices?
