Efforts to reduce the length of stay in a low-intensity ICU: Changes in the ICU brought about by collaboration between Certified Nurse Specialists as head nurses and intensivists.

Abstract

Certified Nurse Specialists (CNS) are advanced practice nurses that often play a role in management. This study aims to investigate whether cooperation between CNSs in the position of Intensive Care Unit (ICU) head nurse and intensivists change the length of stay for ICU patients. A single centered retrospective cohort study design was followed. A multivariable regression analysis was performed to determine whether there is a difference in patients' length of ICU stay for two years before and after CNS as ICU head nurse and an intensivist started collaborating. The patients' diagnosis, age, gender, scheduled/emergency admission, surgical history, length of ICU stay, usage of ventilator, and details of ICU treatment were collected from the institution's electronic medical records. During the study period (April 2015 to March 2019), 3,135 patients were admitted to ICU, with 1,471 in the before collaboration group and 1,664 in the after-collaboration group. Collaboration between the CNS as head nurse and intensivists was significantly associated with shorter length of ICU stay (coefficient -0.03 [95% CI, -0.05-0.01], p < 0.001, t-statistic -3.29). Our main finding illustrates that in low-intensity ICUs, collaboration between CNSs as head nurses and intensivists may reduce patients' length of ICU stay.
