Abstract


Background. Bacteraemia is a common cause of fever among patients presenting to hospitals in  sub-Saharan Africa. The worldwide rise of antibiotic resistance makes empirical therapy increasingly  difficult, especially in resource-limited settings.
Objectives. To describe the incidence of bacteraemia in febrile adults presenting to Maputo Central Hospital (MCH), an urban referral hospital in the capital of Mozambique, and characterise the causative  organisms and antibiotic susceptibilities. We aimed to describe the antibiotic prescribing habits of local doctors, to identify areas for quality improvement.
Methods. Inclusion criteria were: (i) .18 years of age; (ii) axillary temperature .38‹C or .35‹C; (iii) admission to MCH medical wards in the past 24 hours; and (iv) no receipt of antibiotics as an inpatient. Blood cultures were drawn from enrolled patients and incubated using the BacT/Alert automated system (bioMerieux, France). Antibiotic susceptibilities were tested using the Kirby-Bauer disc diffusion method.
Results. Of the 841 patients enrolled, 63 (7.5%) had a bloodstream infection. The most common isolates were Staphylococcus aureus, Escherichia coli, and non-typhoidal Salmonella. Antibiotic resistance was common, with 20/59 (33.9%) of all bacterial isolates showing resistance to ceftriaxone, the broadest-spectrum antibiotic commonly available at MCH. Receipt of insufficiently broad empirical antibiotics was associated with poor in-hospital outcomes (odds ratio 8.05; 95% confidence interval 1.62 - 39.91;  p=0.04).
Conclusion. This study highlights several opportunities for quality improvement, including educating doctors to have a higher index of suspicion for bacteraemia, improving local antibiotic guidelines,  improving communication between laboratory and doctors, and increasing the supply of some key antibiotics.
