Prevalence, Pattern, and Management Outcomes of Chest Injury at Kilimanjaro Christian Medical Centre

Abstract

Background: Chest trauma is a major cause of morbidity and mortality in the region. Lacking data in our environment has been a challenging part of knowing the burden of the problem. Long hospital stays and associated injuries are an essential measure of morbidity. The study results will provide a basis for planning prevention strategies and establishment of treatment protocols.
Objectives: To determine the prevalence, pattern, and management outcomes of chest injury patients at Kilimanjaro Christian Medical Center (KCMC), a Tertiary Hospital in Northern zone Tanzania from October 2021 to April 2022.
Methodology: A hospital-based cross-sectional study was conducted among patients with chest injuries who were admitted and managed at Tertiary Hospital Northern Zone (Kilimanjaro Christian Medical Center-KCMC) in the Emergency medicine and General Surgery departments. Using a designated data collection tool, details of the mechanism of injury, radiological and laboratory investigations, management, and outcomes were recorded.
Results: A total of 114 chest injury patients were studied. Males outnumbered females by a ratio of 7.14:1. Their ages ranged from 2 to 83 years (mean = 36.18 years). The Majority of patients (95.58%) sustained blunt injuries. Road traffic crush was the most common cause of injuries affecting 65.79% of patients. Lung contusion, hemothorax, and rib fractures were the most common type of injuries accounting for 54.4%, 27.2%, and 21.1%, respectively. Associated injuries were noted in 85.7% of patients, and head injury (60.5%) was found in most patients. The Majority of patients (60.5%) were treated successfully with a non-operative approach. Underwater seal drainage was performed at (38.9%). One Patient (0.9%) underwent a thoracotomy. 14% of patients had complications of surgical site infection, and 69% were found in the Majority of patients. The median length of hospital stay was 4.5 days. The mortality rate was 21%
Conclusion: Motor traffic crash was the principal cause of chest trauma. Young male patients were most affected by chest trauma and the majority of patients were treated conservatively. Chest X-ray remains to be the main imaging modality for diagnosing thoracic trauma lesions. Associated injuries such as head injuries, were found to contribute to a high mortality rate.
