Abstract

Surveillance of the infectious risk in neonatal unit in specialized hospital mother-child

Tlemcen 2009-2010

Introduction

The aim of this study was to determine the incidence of nosocomial infections, epidemiological

profile, their place in neonatal morbidity and mortality and to identify the principal factors

associated in a neonatal unit polyvalent Tlemcen.

Materials and methods

The CDC criteria for less than 12 months are used for an incidence study relating to a cohort of

neonates admitted between 2009 and 2010, incorporating a case - control study to understand

the risk factors and diagnostic quality of the unit, based on the study of the microbial ecology

of the service, the Ishikawa diagram, and an audit of hand washing.

Results

A total of 2786 neonates admitted ,472 deaths and 97 infectious episodes are recorded, an

incidence density of 6.27 per 1000 days, a cumulative incidence of 33.7 per 1000, a sex ratio of

0.9. Sepsis is predominant site (76%). The risk factors found are prematurity (p = 0.002), low

birth weight (p <10

-3

), a small height and head circumference (p <10

-3

). The risk of nosocomial

infection associated with severe prematurity is higher (OR = 11.26, p <10

-3

). The presence of

peripheral venous Catheter, oxygen treatment, artificial feeding and the cramming are risk

factors. The risk of death is higher in cases of nosocomial infection (OR = 7, p <10

-3

). The

duration of hospitalization was significantly prolonged in the cases (p <10

-3

Conclusion

The nosocomial infection is an important disease in neonatology, a major risk of mortality and

cause additional costs, related to the extension of stay. The prevention of these infections

requires a reorganization of the NICU according to national standard (national perenatal

program), the fight against prematurity and application of the rules of basic hygiene.
