Guy Lacroix publiera dans la revue Journal of Perinatalogy, un article intitulé "Association of Nursing Overtime, Nurse Staffing and Unit Occupancy with Medical Incidents and Outcomes of Very Preterm Infants’’. L’article est co-écrit avec les médecins Marc Beltempo et Bruno Piedboeuf ainsi qu’avec les spécialistes de la santé infantile Régis Blais, Michèle Cabot.
Voici un résumé de l'étude :
"Lower nurse staffing, higher nursing overtime and high unit occupancy rates have been associated with higher risk of adverse patient events in adult populations, but few studies have focused on preterm infants.We seek to examine the association of nursing overtime, nursing provision and unit occupancy rate with mortality or major morbidity among very preterm infants admitted in a neonatal intensive care unit (NICU). Our analysis focuses on a single centre retrospective cohort study of infants born within 23-29 weeks of gestational age or birth weight < 1000g admitted at a 56 bed, Level III NICU. Nursing overtime ratios (nursing overtime hours/total nursing hours), nursing provision ratios (nursing hours/ recommended nursing hours based on patient dependency categories) and unit occupancy rates were pooled for all shifts during NICU hospitalization of each infant. Log-binomial models assessed their association with the composite outcome (mortality or major morbidity). Of the 257 infants that met the inclusion criteria, 131 (51%) developed the composite outcome. In the adjusted multivariable analyses, high (>3.4%) relative to low nursing overtime ratios (≤ 3.4%) were not associated with the composite outcome (relative risk [RR], 0.93; 95% confidence interval [CI], 0.86-1.02). High nursing provision ratios (>1.0) were associated with a lower risk of the composite outcome relative to low ones (≤1.0) (RR, 0.81; 95% CI 0.74-0.90). NICU occupancy rates were not associated with the composite outcome (RR, 0.98; 95% CI 0.89-1.07, high (>100%) vs low (≤100%)). We conclude that high nursing provision ratio during NICU hospitalization is associated with a lower risk of a composite adverse outcome in very preterm infants."
