During her clinical training, resident Dr. Chia-Ying Wu has demonstrated exceptional performance. In addition to managing a heavy clinical workload, she has exhibited solid research capabilities, clinical reasoning, and significant potential for academic development. Her research findings have been published in the international journal BMC Infectious Diseases. The paper, titled “Prognostic factors for mortality and respiratory failure in hospitalized patients with COVID-19 after three-dose vaccination: a retrospective cohort study during the Omicron period”, was published on December 25, 2025, marking a significant achievement in the integration of residency training and clinical research.
This study focuses on the analysis of prognostic factors for mortality and respiratory failure in hospitalized patients who had received three doses of a COVID-19 vaccine during the Omicron wave. Conducted at Taipei Veterans General Hospital, the study included 620 hospitalized adult patients. The results showed a 28-day mortality rate of 7.9%. A higher comorbidity burden, higher WHO ordinal scale, higher neutrophil-to-lymphocyte ratio (NLR), and thrombocytopenia were all associated with an increased risk of mortality. Furthermore, among patients who did not initially require invasive ventilation, 6.6% subsequently progressed to requiring invasive mechanical ventilation. Hematologic malignancy, metastatic cancer, higher WHO ordinal scale, higher NLR, and secondary bacterial infection were identified as significant risk factors for respiratory failure. This study holds substantial practical significance for the early identification and clinical management of high-risk patients during the current endemic phase of COVID-19.
Completing research of such clinical value and academic significance during residency training, and achieving publication in an international journal, is truly commendable. This accomplishment not only demonstrates Dr. Wu's excellent abilities in research design, data analysis, and academic writing but also embodies the value of integrating clinical practice with evidence-based research. This study was co-mentored by Dr. Yi-Tsung Lin, whose interprofessional collaboration further enhanced the study's integrity and clinical impact. We extend our sincere congratulations and thank all team members who contributed to this research. We look forward to Dr. Wu's continued excellence in both her clinical and academic pursuits.
