Outcomes of post-traumatic osteomyelitis in a conflict setting: a retrospective cohort study in Gaza
AIM
Assess the microbiology and treatment outcomes of post-traumatic osteomyelitis (PTO) patients in Medecins Sans Frontieres (MSF) supported reconstructive surgical facilities in Gaza, pre-October 7, 2023, and identify recurrence risk factors.
BACKGROUND
PTO is common among war-wounded in conflict-affected settings in the Middle East. The ongoing war in Gaza since October 2023, has severely disrupted healthcare, increasing suspected and sub-optimally treated PTO, and related literature is scarce.
METHODS
Two-centre retrospective cohort study including PTO patients diagnosed by microbiological confirmation via bone biopsy and treated between December 6, 2018 and September 8, 2021, with follow-up until January 31, 2022. Differences between multi-drug resistant (MDR) and non-MDR, polymicrobial and monomicrobial PTO were assessed. Predictors of recurrence were identified using cox proportional hazards multivariate regression.
RESULTS
202 patients with 275 PTO episodes and 441 isolates were included. MDR was present in 53% of episodes; 43% episodes were polymicrobial; recurrence occurred in 26%. Twenty patients (10%) underwent amputation. Staphylococcus aureus was the most prevalent (35%) isolate (62% methicillin-resistant), followed by 13% Enterobacterales (59% extended-spectrum beta-lactamase producers), 10% Pseudomonas aeruginosa and 3% Acinetobacter species. The 6-month survival (recurrence-free) probability was 79% (95% CI: 73-86) decreasing to 56% (95% CI: 47 - 68) by 24 months. Significant risk factors of recurrence included up to 3 procedures, fibula fractures, PTO with Enterobacter cloacae or Staphylococcus aureus.
CONCLUSIONS
Managing PTO in Gaza is complex. Rebuilding the healthcare system, strengthening local capacities, ensuring access to necessary resources are essential for the long-term management of PTO in Gaza.
BACKGROUND
The history of conflicts in the Middle East has resulted in a high burden of complications from conflict-related wounds like posttraumatic osteomyelitis (PTO). This is particularly challenging to manage in settings like Mosul, Iraq and Gaza, Palestine, where healthcare systems are weakened. In nonconflict settings, PTO caused by Pseudomonas aeruginosa (PAPTO) can lead to >20% of treatment failures. We aim to describe the clinical characteristics, outcomes, and management, in PAPTO patients admitted to Médecins Sans Frontières (MSF) facilities in Mosul and Gaza between 1 April 2018 and 31 January 2022.
METHODS
We conducted a retrospective cohort study on patients with PAPTO diagnosed with culture of intraoperative bone biopsy, using routinely collected data.
RESULTS
Among 66 PAPTO episodes from 61 enrolled patients, 37.9% had a multidrug-resistant Pseudomonas aeruginosa, with higher antibiotic resistance in Gaza. Polymicrobial infections were prevalent (74.2%), mainly involving Staphylococcus aureus (74.1%), being predominantly methicillin-resistant (95.0%). Overall, 81.7% received appropriate antibiotic treatment, with monotherapy used in 60.6% of episodes and a median treatment duration of 45.5 days. Recurrence was observed in 24.6% of episodes within a median of 195 days (interquartile range, 64-440 days). No significant differences were found in recurrence rates based on the type of antibiotic treatment (mono- or dual therapy) or episode (mono- or polymicrobial).
CONCLUSIONS
Management of PAPTO in the conflict-affected, low-resource settings of Mosul and Gaza achieved a recurrence rate aligned with global reports through appropriate and targeted antibiotic use, primarily in monotherapy, provided over a mean treatment duration of 45.5 days.
Limb salvage by ortho-plastic teams is the standard protocol for treating open tibial fractures in high-income countries, but there’s limited research on this in conflict settings like the Gaza Strip. This study assessed the clinical impact of gunshot-related open tibial fractures, compared patient management by orthopedic and ortho-plastic teams, and identified the risk factors for bone non-union in this context.
METHODS
A retrospective review of medical records was conducted on Gaza Strip patients with gunshot-induced-open tibial fractures from March 2018 to October 2020. Data included patient demographics, treatments, and outcomes, with at least one year of follow-up. Primary outcomes were union, non-union, infection, and amputation.
RESULTS
The study included 244 injured individuals, predominantly young adult males (99.2%) with nearly half (48.9%) having Gustilo-Anderson type IIIB fractures and more than half (66.8%) with over 1 cm of bone loss. Most patients required surgery, including rotational flaps and bone grafts with a median of 3 admissions and 9 surgeries. Ortho-plastic teams managed more severe muscle and skin injuries, cases with bone loss > 1 cm, and performed less debridement compared to other groups, though these differences were not statistically significant. Non-union occurred in 53% of the cases, with the ortho-plastic team having the highest rate at 63.6%. Infection rates were high (92.5%), but no significant differences in bone or infection outcomes were observed among the different groups. Logistic regression analysis identified bone loss > 1 cm, vascular injury, and the use of a definitive fixator at the first application as predictors of non-union.
CONCLUSIONS
This study highlights the severity and complexity of such injuries, emphasizing their significant impact on patients and the healthcare system. Ortho-plastic teams appeared to play a crucial role in managing severe cases. However, further research is still needed to enhance our understanding of how to effectively manage these injuries.
Medecins Sans Frontieres (MSF) is known for its work providing surgical care for victims of violent trauma (VT) in conflict zones. However, the trauma centers also deal with road traffic accidents (RTAs) which may require different staffing, facilities and supplies as compared with those required for VT. This study aimed to compare differences in types of injuries, clinical outcomes, and resources needed to properly operate trauma centers in low and middle-income countries.
MATERIAL AND METHODS
This was a retrospective analysis of routine program data of >70,000 patient presentations in the emergency, in-patient, and operating departments of 2 of MSF’s major trauma centers, in Kunduz (Afghanistan) and Bujumbura (Burundi), using data from 2011 to 2018.
RESULTS
RTAs comprised a significant proportion of overall presentations to these centers (23% in Kunduz and 56% in Bujumbura). RTA patients presented with different patterns of injury, with higher rates of fractures, extremity injuries, and traumatic brain injury. RTA patients were 2.3 times more likely to have a peripheral injury (extremities and head) as VT patients, and 12.5 times more likely to undergo an orthopedic procedure. VT patients had higher rates of abdominal injury. However, there was no statistically significant difference in overall mortality and length of stay between the 2 groups.
CONCLUSION
This study demonstrates that trauma centers, even in zones of conflict, need to be prepared and resourced to manage RTA cases. Policy-makers in such centers should be aware of the different injury patterns associated with this patient group and have appropriate, sustainable capacity to manage RTA trauma, particularly in terms of management of orthopedic injuries.
Access to surgical care is a global health burden. A broad spectrum of surgical competences is required in the humanitarian context whereas current occidental surgical training is oriented towards subspecialties. We proposed to design a course addressing the specificities of surgery in the humanitarian setting and austere environment.
METHOD
The novelty of the course lies in the implication of academic medical doctors alongside with surgeons working for humanitarian non-governmental organizations (NGO). The medical component of the National Defense participated regarding particular topics of war surgery. The course is aimed at trained surgeons and senior residents interested in participating to humanitarian missions.
RESULTS
The program includes theoretical teaching on surgical knowledge and skills applied to the austere context. The course also covers non-medical aspects of humanitarian action such as international humanitarian law, logistics, disaster management and psychological support. It comprises a large-scale mass casualty exercise and a practical skills lab on surgical techniques, ultrasonography and resuscitation. Attendance to the four teaching modules, ATLS certification and succeeding final examinations provide an interuniversity certificate.
30 participants originating from 11 different countries joined the course. Various surgical backgrounds, training levels as well as humanitarian experience were represented.
Feedback from the participants was solicited after each teaching module and remarks were applied to the following session. Overall participant evaluations of the first course session are presented.
CONCLUSION
Teaching humanitarian surgery joining academic and field actors seems to allow filling the gap between high-income country surgical practice and the needs of the humanitarian context.
