ABSTRACT
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.
ABSTRACT
OBJECTIVES: Iraq has suffered unrest and conflicts in the past decades, leaving behind a weakened healthcare system. In 2018, Médecins Sans Frontières (MSF) opened a tertiary orthopaedic care centre in Mosul providing reconstructive surgery with access to microbiological analysis. METHODS: A retrospective cross-sectional analysis of microbiological and clinical data of patients admitted between April 2018 and December 2019. RESULTS: There were 174 patients who were included in this study; there were more males than females (135 to 38, respectively), and the mean age was 32.6 y. Of the 174 patients, the majority had more than one bacterial isolate detected (n = 122, 70.1%); 141 (81.0%) had at least one multidrug-resistant (MDR) isolate detected during their hospital stay. Staphylococcus aureus (n = 197, 48.2%) was the most common organism isolated. Overall, most isolates detected were MDR (n = 352, 86%), mostly methicillin-resistant S. aureus (n = 186, 52.8%) or extended-spectrum beta-lactamase-producing Enterobacterales (n = 117, 33.2%). Among patients admitted to the operating department (n = 111, 63.7%), 81.1% (n = 90) were admitted for violent trauma injuries. Patients who had more than one procedure performed per surgery had significantly increased odds of having at least one MDR organism isolated (OR 8.66, CI 1.10-68.20, P = 0.03). CONCLUSION: This study describes a high prevalence of antibiotic resistance in patients with trauma-related wounds in Mosul, Iraq. It highlights the importance of microbiological analysis and ongoing surveillance to provide optimal treatment. Additionally, it underscores the importance of infection prevention and control measures as well as antibiotic stewardship.
