摘要

Introduction

We reviewed culture-confirmed healthcare-associated outbreaks linked to bacterial and fungal contamination of intravenous fluids and medicines (further “infusates”) in low-income countries and lower and upper middle-income countries (LIC, Lower-MIC and Upper-MIC). We assessed the scope, impact, risks, and gaps in knowledge.

Methodology

Literature search including PubMed, Web of Science, Worldwide Database for Nosocomial Outbreaks, Global Health, and Google Scholar. National essential medicine lists (NEMLs) of sub-Saharan countries were searched for listing of pediatric infusates.

Results

Between 1975 and 2023, 50 articles were retrieved. Median (range) number of patients affected was 12 (3–185); 74.2% (761/1025) of all patients affected were children. All patients presented with bloodstream infections; median case fatality ratio was 21.1% (0.0–87.5%). Upper-MIC, Lower-MIC and LIC accounted for 21, 25 and 4 articles, respectively. Most frequently affected wards were neonatal and adult intensive care units (19 and 6 articles). The 50 articles revealed 59 contaminated infusates: IV fluids (n = 37), including TPN (n = 10, of which 8 were from Upper-MIC), and IV medicines (n = 22), comprising amongst others propofol (n = 4) and Water for Injection (n = 3). The 63 isolates included Enterobacterales (46.0% (29/63) of isolates), non-fermentative Gram-negative bacteria (NFGNB, 47.6% (30/63)), fungi (4.8%, 3/63)) and Bacillus circulans (1.6% (1/63)). Among the Enterobacterales, the genera Serratia, Klebsiella, and Enterobacter represented 82.8% (24/29) of isolates. Burkholderia cepacia was the most frequent NFGNB (53.3% (16/30) isolates). Excluding TPN, 18 IV fluids and 7 IV medicines (representing half (51.0%, (25/49) of these infusates) were incorrectly used as multidose vial. A third (33.9%, 20/59) of infusates in 40.0% (20/50) of articles was intrinsically contaminated. In LIC and LMIC, staff in neonatology units turned to in-ward preparation of infusates because of lack of access to pediatric IV formulations and sizes. Less than a third (31.8%, 18/44) of the NEMLs listed neonatal IV premixtures.

Conclusion

Infusate contamination is a serious, underreported risk especially for children in LICs and Lower-MIC. Outstanding issues are access to pediatric infusates and preventing in-ward preparation of IV medicines in LIC and Lower-MIC, and safe preparation and administration of TPN in Upper-MIC.
