Concordance Between the Germs of Hospital Surfaces and those Isolated Nosocomial Infections in Parturient in Public Hospitals in Lubumbashi

Abstract

Introduction: The objective of the study was to compare the germs found on hospital surfaces and those found in biological fluids of parturients hospitalized in public hospitals in Lubumbashi. Methods: Data collection was performed on the surfaces by swabbing, by using ISO / DIS 14698-1. Similarly, samples of biological fluids were taken and all were analyzed in the laboratory of the university clinics in Lubumbashi to investigate the susceptibility and antibiotype. Kappa coefficient was used to study the correlation between the identified germs on hospital surfaces and those found in biological fluids of parturient at p ≤ 0.05 significance. Results: The antibiotype showed that the isolated germs on surfaces are the same strains as those isolated in pus, blood and urine of pregnant women. However, we noted a significant correlation of 0.02 between the surfaces germs and bacteria isolated in liquid surgical site. The probability of a woman in labor hospitalized in a public obstetric setting in Lubumbashi of contracting a nosocomial infection (NI) in a surface containing the same germs as that in question for this infection was 14.3% for Citrobacter freundi, 58.6%. for Escherichia coli, 19.2% for Klebsiella spp, 28.6% and this concordance was nevertheless negligible (0.10). We noticed that as long as hospital hygiene conditions improved, that is, with a high score, the risk of nosocomial infections decreased. Conclusion: The hospital environment contributes to the occurrence of (NI) in these public hospitals, however, note that there are several factors that influence the occurrence of these infections.
