Knowledge on Palliative Care and Associated Factors among Nurses in Ethiopia: A Systematic Review and Meta-Analysis

Palliative care is a multidisciplinary team-based care for patients facing life-threatening illness and their families which addresses their physical, psychological, social, and spiritual needs to improve the quality of care. There is a strategy for an increase in palliative care services by integrating with the healthcare system. Therefore, this systematic review and meta-analysis was aimed to assess the overall pooled prevalence of nurses' knowledge towards palliative care in Ethiopia.

PubMed/MEDLINE, HINARI, EMBASE, Scopus, Google Scholar, and African Journals OnLine (AJOL) were the databases used to search for articles. Cochrane I ² statistics and Egger's test were done to check heterogeneity and publication bias, respectively. Subgroup analysis by region, study period, and sample size was done due to the presence of heterogeneity. Sensitivity analysis was also done to detect the presence or absence of an influential study.

Nine studies with a total of 2709 study participants were included in the final analysis. The overall pooled prevalence of nurses' knowledge towards palliative care was 45.57% (95% CI: 35.27-55.87). Educational status and palliative care training were significantly associated factors with the level of nurses' knowledge towards palliative care. B.S. degree holder nurses (AOR = 3.01; 95% CI: 1.50-6.02) and nurses who had palliative care training (AOR = 4.64; 95% CI: 2.37-9.08) were found to be significantly associated factors with the nurses' level of knowledge.

More than half of nurses had poor knowledge of palliative care. Educational status of nurses and palliative care training were significantly associated factors with the nurses' level of knowledge about palliative care. Therefore, palliative care training and improving nurses' careers through continuous professional development should be focused on regularly to improve nurses' knowledge about palliative care.
