Objective: To determine whether a nursing intervention delivered at emergency department (ED) discharge would reduce ED revisits. Method: A randomized study was conducted in the ED of a tertiary cardiac hospital in Montreal, Quebec. Between November 2006 and March 2010, 3,795 patients were assessed for eligibility based on two risk factors for ED revisits ($ 1 ED visit in the past year and $ 6 medications); 132 were randomized to the experimental group (EG) and 133 to the control group (CG). The intervention included one nurse-patient meeting before leaving the ED, with two additional telephone contacts over the next 2 weeks. The primary outcome was time to ED revisits within 30 days after discharge. Secondary outcomes included time to ED revisits over 90, 180, and 365 days and hospitalizations over 30, 90, 180, and 365 days. Results: A planned interim analysis that stopped the study with half of the planned sample showed that the time to ED revisits was similar in both groups at 30 days (p 5 0.81; revisits: 18.2% in EG, 19.6% in CG), 90 days (p 5 0.44), 180 days (p 5 0.98), and 365 days (p 5 0.75). The only difference identified was a lower hospitalization proportion at 180 days in the EG group (13.6% v. 24.1%; p 5 0.038). Conclusions: These findings are consistent with previous research showing that few ED-based interventions are successful in reducing ED returns. Factors other than those targeted by the intervention, including an improvement in usual care, may explain the findings.
RÉ SUMÉObjectif: L'é tude visait à dé terminer si une intervention en soins infirmiers, appliqué e au moment du congé du service des urgences (SU) permettrait de ré duire le nombre de reconsultations à ce mê me service. , ce qui a mis fin à l'é tude, au moment où la moitié de la taille pré vue de l'é chantillon avait é té atteinte. La seule diffé rence observé e é tait une diminution de la proportion des hospitalisations au bout de 180 jours dans le GE (13.6% v. 24.1%; p 5 0.038). Conclusions: Les ré sultats vont dans le mê me sens que ceux d'autres é tudes, selon lesquels peu d'interventions ré alisé es au SU permettent de ré duire le nombre de reconsultations à ce mê me service. Des facteurs diffé rents de ceux ciblé s par l'intervention, notamment une amé lioration des soins courants, pourraient expliquer ces ré sultats.
