Abstract Background Nurses' burnout and psychological well‐being are a significant concern during the pandemic. Aims The aim of this study is to (i) examine the level of burnout, anxiety, depression, perceived stress and self‐rated health for nurses at two time‐points, 2020 and 2021, and (ii) examine the socio‐demographic characteristics, work‐related factors and perceived workplace support factors in relation to the level of burnout. Methods This is a cross‐sectional study with a longitudinal approach. A convenience sample of registered nurses who worked in an acute care tertiary hospital in Singapore were surveyed during two time‐points. Participants' health, socio‐demographic characteristics, work‐related factors and perceived workplace support factors were collected. Results Among the 179 nurses, there was a significant increase in burnout level, poorer self‐rated health and reduced job dedication. A decrease in the percentage of nurses who felt appreciated at work was reported in 2021 (p = 0.04). Nurses who felt their team was not working well together were 3.30 times more likely to experience burnout (95% CI 1.12 to 9.69; p = 0.03). Nurses who reported that they never felt appreciated by their department/hospital were 8.84 times more likely to experience burnout (95% CI 2.67 to 29.21; p < 0.001). Nurses with poorer self‐rated health were more likely to report burnout (95% CI: 1.32–6.03; p = 0.008). Conclusion Nurses had an increased experience of burnout, reduced job dedication and poorer self‐rated health after the outbreak. Implications for Nursing Management Interventions at the departmental and organizational levels are needed to improve the workplace support. Strategies to support nurses' psychological well‐being during the aftermath of COVID‐19 are vital to managing nurses' burnout and improving job dedication and self‐rated health.
