AIMS: A meta-analysis was conducted of the prevalence rates of compassion satisfaction, compassion fatigue and burnout to identify the factors influencing these rates. BACKGROUND: The extents of compassion fatigue and burnout adversely affect nursing efficiency. However, the reported prevalence rates vary considerably. METHODS: Data were acquired from electronic databases. Random effects meta-analyses were performed to obtain pooled estimates of the prevalence rates of compassion satisfaction, compassion fatigue and burnout and their respective instrumental scores. Meta-regression analyses were performed to identify factors influencing these rates. RESULTS: Data from 21 studies were used for the meta-analysis. The prevalence rates of compassion satisfaction, compassion fatigue and burnout were 47.55%, 52.55% and 51.98%, respectively. The possession of Bachelor's or Master's degrees by the nurses was significantly inversely associated with the percent prevalence of compassion fatigue (coefficient: -1.187) and burnout (coefficient: -0.810). The compassion fatigue score was also significantly inversely associated with nursing status as registered or licensed practical nurse (coefficient: -0.135). CONCLUSION: In nursing, the prevalence rates of compassion fatigue and burnout are high. Better education and training may have a moderating effect on compassion fatigue and burnout and could improve the quality of life of nurses.
