背景：八仙樂園粉塵爆炸是震驚國內外的一大公安事件，護理人員竭盡心力照顧大量 燒燙傷病人創造低死亡率的世界奇蹟，但過去很少探討護理人員對重大災難事件病人照顧 負荷之研究。目的：本研究探討護理人員對八仙塵爆燒傷病人照顧負荷及其影響因素。方 法：採橫斷式、描述性、相關性研究設計，以方便取樣收集北部某醫學中心199位護理人員 資料，使用基本資料、壓力知覺量表、匹茲堡睡眠品質量表、職場疲勞量表、社會支持量 表及專業照顧團隊負荷量表等進行資料收集。以t檢定、單因子變異數分析、皮爾森積差相 關進行單變項推論統計，並使用一般線性回歸模式分析影響護理人員專業照顧負荷之因 子，以p <0.05 為統計上之顯著意義。結果：研究結果顯示護理人員的工作年資高(p = 0.009)、社會支持程度高(p = 0.009)、有接受燒燙傷相關教育訓練課程者(p < 0.001)，其專業 照顧團隊負荷程度愈低；壓力知覺程度高(p < 0.001)、職場疲勞程度高(p < 0.001)者，其專 業照顧團隊負荷程度愈高。結論：由本研究結果發現工作年資、燒燙傷相關教育訓練課 程、社會支持程度、壓力知覺程度、職場疲勞程度是影響護理人員照顧八仙塵爆燒傷病人 專業照顧團隊負荷的重要因素。因此，建議提供相關教育訓練課程、增加親友及同儕長官 的支持，創造友善職場以降低其壓力與疲勞，進而減輕其專業照顧團隊負荷，提升護理人 員留任率。

Background: The Formosa Fun Coast explosion was a major public disaster that caused shock internationally. The nursing staff made an all-out effort to care for everyone injured in the explosion and performed a miracle in achieving the lowest mortality rate in the world. However, few studies have explored the caregiver burden among nursing staff confronted with major disaster events. Objectives: This study aimed to investigate caregiver burden and related factors among nursing staff who responded to the Formosa Fun Coast explosion. Methods: We adopted a cross-sectional, descriptive, and correlational study design, and a convenience sampling method. Data were collected on demographic characteristics; additional measures included the Perceived Stress Scale (PSS), Pittsburgh Sleep Quality Inventory, Occupational Burnout Inventory (OBI), Social Support Scale, and Professional Care Team Burden Scale (PCTB). Participants were 199 nursing staff in a medical center in North Taiwan. We performed univariate inferential statistics including t-tests, one-way ANOVA, Pearson’s correlation coefficients, and a general linear regression model to analyze the factors affecting care burden among nursing staff. A threshold of P <0.05 was set as the level of statistical significance. Results: Nurses who had more years of experience (p=0.009), higher social support (p=0.009), and who had received a burn related training program (p<0.001), had significantly lower PTCB scores. Otherwise, nurses with higher levels of PSS (p<0.001) and OBI (p<0.001) had higher PTCB scores. Conclusion: Based on this study, it is proposed that seniority, having received a burn related training program, social support, perceived stress, and the level of occupational burnout were the important predictors of professional team care burden among nursing staff who cared for casualties of the Formosa Fun Coast explosion. Therefore, it is suggested to provide burn-related training programs, increase social support from friends and colleagues, and create friendly workplaces to decrease stress and fatigue in order to reduce the professional care burden and improve retention rates of nurses.
