Management of imported malaria in the emergency department: Adequacy compared to guidelines, and impact of the SARS-CoV-2 pandemic.

OBJECTIVES

Adequacy of imported malaria management with respect to guidelines in emergency departments (ED) is low. We aimed to identify factors associated with this non-compliance, and a potential impact of the SARS-CoV-2 pandemic.

PATIENTS AND

METHODS

Patients presenting with imported malaria at the ED of the hospital of Melun (France), from January 1, 2017 to February 14, 2022 were retrospectively included.

RESULTS

Among 205 adults and 25 children, biological criteria of severity were fully assessed in 10% of cases; lactates (40%) and blood pH (21%) levels were the main missing variables. Of 74 patients (32%) with severe malaria, 13 were misclassified as uncomplicated malaria. The choice and dosage of treatment were adequate in 85% and 92% of cases, respectively. Treatment conformity was lower in severe malaria cases than in non-severe malaria cases (OR 0.15 [95% CI 0.07-0.31]), with oral treatment in 17 patients with severe malaria; conformity was higher in the intensive care unit (OR 4.10 [95% CI 1.21-13.95]). Patients with severe malaria were more likely to start treatment within 6hours than patients with uncomplicated malaria (OR 1.97 [95% CI 1.08-3.43]), as were patients infected by P.falciparum compared to other species (OR 4.63 [95% CI 1.03-20.90]). Consulting during the SARS-CoV-2 pandemic was the only organizational factor associated with a lower probability of adequate management (OR 0.42 [95% CI 0.23-0.75]).

CONCLUSION

Initial evaluation of malaria severity and time to treatment administration could be improved. These have been adversely impacted by the SARS-CoV-2 pandemic.
