The Effect of Liaison Nurse Service on Patient Outcomes after Discharging From ICU: a Randomized Controlled Trial

Abstract

Introduction: Recent studies suggest that liaison nurse intervention might be effective to solve the gap between intensive care unit and wards, but little studies are known about the effect of this intervention. The aim of this study was to investigate the effect of liaison nurse service on patient outcomes after discharging from intensive care unit. Methods: In this single blinded randomized controlled trial, a total of 80 patients were selected by convenience sampling method from two teaching hospitals located in Tehran, Iran. Patients were randomly allocated to either the experimental or the control groups. Patients in the experimental group received post-ICU care from a liaison nurse and patients in the control group received the routine care. After the intervention, patients’ vital signs, level of consciousness, length of hospital stay, need for re-hospitalization in ICU, and satisfaction with care were measure. Data were analyzed by SPSS Ver.13 software. Results: None of the participants experienced ICU re-hospitalization. According to the result and there were no significant differences between the study groups regarding heart rate, respiratory rate, systolic blood pressure, post-ICU level of consciousness, satisfaction with care, and length of hospitalization in medical-surgical wards. However, the study groups differed significantly in terms of body temperature. Conclusion: Care services provided by an ICU liaison nurse has limited effects on patient outcomes. However, considering the contradictions among the studies, further studies are needed for providing clear evidence about the effectiveness of the liaison nurse strategy.
