Effects of implementation of healthcare associated infection surveillance and interventional measures in the neonatal intensive care unit: Small steps matter

Abstract

Purpose: Neonatal sepsis has been a global concern considering the mortality and morbidity. This study was undertaken to determine the effects of implementation of interventions namely healthcare associated infection (HAI) surveillance and hand hygiene (HH) monitoring in the neonatal intensive care unit (NICU). Materials and methods: The cohort study was conducted in the NICU of a tertiary care hospital over a period of June–September 2021 (pre-intervention) to October–March 2022 (post-intervention). HAI surveillance of primary bloodstream infections (BSI) and HH monitoring was initiated as interventions post outbreak due to non-albicans Candida (NAC). The primary outcome of the interventions was to record any improvement in HH rates or any change in HAI rates in the 6 months intervention period. Characteristics of the pre- and post-intervention period were compared by Fisher exact test. Results: There was significant reduction in BSI cases in the post-intervention period (p ​< ​0.05). Mortality and BSI due to NAC were significantly more in the pre-intervention period even though low birth weight neonates (<2500 ​g) were significantly more in the post-intervention period (p ​< ​0.05). The HAI rate for primary BSI in the NICU was 10.82 per 1000 patient days. The overall adherence rate to HH was 10.68% (complete) and 73.35% (partial). HAI rates were seen to change reciprocally with changes in HH rates. Conclusions: HAI rates of primary BSI in the NICU could be regulated by the effective implementation of HAI surveillance, HH monitoring, feedback meetings with the NICU staff and other simple interventional measures even in resource-limited setups. © 2023 Indian Association of Medical Microbiologists
