34: Nursing Overtime Increases the Risk of Medical Incidents in the NICU
Notice bibliographique
Résumé
Adult studies have shown that increased fatigue in workers is associated with a higher risk of error. Medical incidents are preventable causes of adverse events in the hospital setting. To our knowledge, no study has assessed the impact of nurse overtime on the risk of medical incidents in the neonatal intensive care unit (NICU). The objective of this study was to assess the impact of nurse overtime on the risk of medical incidents on all infants hospitalised in the NICU. We conducted a retrospective study on all infants (n=7473) admitted in the CHU de Québec NICU (capacity of 51 beds) from April 1, 2008 to March 31, 2013. Administrative data (overtime hours per day) was obtained from the database Logibec, patient information was obtained from Med-Echo and information on medical incidents was obtained from the local incident reporting database Gesrisk. We assessed the association between administrative data and patient outcomes by using logit and probit models. Two-sample test of proportions and t test were used to assess risk factors. The mean total of worked overtime was 22.7±20.7 h. The average overtime as percentage of total daily hours of work was 4.0±3.4%. There were a total of 601 medical incidents that were reported during the study period. The most common categories of incidents were related to medication (78.9%), feeding (7.7%) and treatment (7.1%). On average, incidents happened on day of life 9.5±1.1. A total of 428 (5.7%) patients had at least one medical incident. Patients who had a medical incident had significantly smaller gestational age (32.6±0.25 weeks compared to 36.3±0.1 weeks; P<0.001)) and had a smaller birth weight (2022.2±55.3 g compared to 2786.7±10.7 g; P<0.001). Days of higher overtime (expressed as percentage of total worked hours) were significantly associated with an increased risk of medical incidents (P=0.02). Adjusted risk of suffering from a medical incident was significantly higher on days of high overtime (>8% of all hours worked) (OR=1.34; P=0.03). On days of very high overtime (>12% of all hours worked), the risk of medical incidents was greatest (OR= 1.62; P=0.045). In our study, periods of high overtime were significantly associated with an increased risk of medical incidents in the NICU. Preterm infants had the highest risk of having a medical incident. This suggests that re-organising the medical workforce to reduce nursing overtime should become an integral part in improving patient care and reducing risk of medical errors in the NICU.

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
