RESUMO
Objective: To describe the treatment outcomes of patients who underwent tube thoracostomy for pleural complications in patients with COVID-19 and determine the association between patient profile and treatment outcomes. Methods: A single-institution retrospective review of patients who underwent tube thoracostomy for complications of COVID-19 infection in the University of the Philippines - Philippine General Hospital (UP-PGH) from March 30, 2020, to March 31, 2021, was performed. These patients' demographic and clinical profiles were evaluated using median, frequencies, and percentages. The association between patient profile, and mortality and reintervention rates was assessed using univariable Cox proportional hazards regression analysis. Results: Thirty-four (34) of 3,397 patients (1.00%) admitted for COVID-19 pneumonia underwent tube thoracostomy. Of these, 34, 47.06% were male, 52.94% were female, the median age was 51.5 years old, 85.29% had comorbid conditions, and 29.41% had a previous or ongoing tuberculous infection. The most common indication for tube thoracostomy was pleural effusion (61.76%), followed by pneumothorax (29.41%), and pneumo-hydrothorax (8.82%). The mortality rate was 38.24%, and the reintervention rate was 14.71%. Intubated patients had 14.84 times higher mortality hazards than those on room air. For every unit increase in procalcitonin levels, the mortality hazards were increased by 1.06 times. Conclusion: An increasing level of oxygen support on admission and a level of procalcitonin were directly related to mortality risk in COVID-19 patients who underwent tube thoracostomy for pleural complications. There is insufficient evidence to conclude that patient-related, COVID-19 pneumonia-related, and procedure-related factors included in this study were significantly associated with reintervention risk.
