Reference des cas de traumatisme par arme à feu en Afrique

BACKGROUND

In a war-torn African country, Médecins Sans Frontières supports two regional referral hospitals to address emergencies, including the treatment of firearm-related traumas. It facilitates access to healthcare and referrals, which are often hindered due to non-medical reasons.

OBJECTIVE

To determine the factors influencing the unfavourable outcome of cases referred for firearm trauma (December 2020-November 2021).

METHOD

This was a cross-sectional study using routinely collected data.

RESULTS

A total of 381 patients who were victims of firearm-related trauma were admitted, with an average age of 29 years; 28.3% had severe injuries, including thoraco-abdominal injuries and fractures. The mortality rate was 4.9%, and 7.9% left against medical advice. Patients affiliated with the irregular armed forces accounted for 45.4%, and had a two-thirds higher rate of unsuccessful referral for non-medical reasons. Patients with severe injuries at triage, affiliation with the irregular forces and being in the regular army had 2 times (P < 0.01), 5.9 times (P < 0.01) and 8.1 times (P < 0.01), respectively, a higher risk of an unfavourable outcome.

CONCLUSION

Serious cases caused by firearm injuries were more likely to have an adverse outcome. The risk was higher in those with a specific affiliation, who were more often denied access to higher referral care based on socio-political rather than medical reasons.

Rectal screening displays high negative predictive value for bloodstream infection with (ESBL-producing) Gram-negative bacteria in neonates with suspected sepsis in a low-resource setting neonatal care unit

OBJECTIVES

We analysed the concordance of rectal swab isolates and blood culture for Gram-negative bacteria (GNB) isolates in neonates with a suspicion of neonatal sepsis admitted to a neonatal care unit in Haiti.

METHODS

We matched pairs of blood and rectal samples taken on the date of suspected sepsis onset in the same neonate. We calculated the proportion of rectal isolates in concordance with the blood isolates by species and genus. We calculated the negative predictive value (NPV) for GNB and extended-spectrum β-lactamase (ESBL)-producing GNB for all rectal and blood isolate pairs in neonates with suspected sepsis.

RESULTS

We identified 238 blood and rectal samples pairs, with 238 blood isolate results and 309 rectal isolate results. The overall concordance in genus and species between blood and rectal isolates was 22.3% [95% confidence interval (CI) 17.4-28.0%] and 20.6% (95% CI 16.0-26.2%), respectively. The highest concordance between blood and rectal isolates was observed for samples with no bacterial growth (65%), followed byKlebsiella pneumoniae (18%) and Klebsiella oxytoca (12%). The NPV of detecting GNB bacterial isolates in rectal samples compared with those in blood samples was 81.6% and the NPV for ESBL-positive GNB was 92.6%.

CONCLUSIONS

The NPV of rectal swab GNB isolates was high in all patient groups and was even higher for ESBL-positive GNB. Clinicians can use the results from rectal swabs when taken simultaneously with blood samples during outbreaks to inform the (de-)escalation of antibiotic therapy in those neonates that have an ongoing sepsis profile.
