The role of a nurse case manager in implementing a critical pathway for infrainguinal bypass surgery.
BACKGROUND
A previous study showed the effectiveness of a clinical pathway for infrainguinal bypass surgery in reducing postoperative length of stay (LOS) in an acute care setting. Most of the deviations from the pathway were due to patient factors (50%) and/or external disposition problems (30%), but 20% were related to physician or system problems that could potentially be modified. The current study examined those factors influencing LOS following infrainguinal bypass surgery and the impact of daily rounds by a nurse case manager--a vascular nurse specialist--on LOS and pathway deviations.


METHODS
Data were collected through detailed chart review and prospective tracking of pathway deviations. LOS was compared in 58 patients on the modified pathway (with the nurse case manager) to 69 patients on the original pathway and 67 prepathway controls. Multivariate analysis was used to identify factors influencing postoperative LOS and to compare LOS among the three groups.


RESULTS
Use of a nurse case manager significantly reduced physician-related deviations, from the pathway from 10% to 0% (p = .015), and reduced system-related deviations from 3% to 0%. Median postoperative LOS was 7 days before the pathway was begun, 6 days with the original pathway, and 5 days after the introduction of a vascular nurse specialist (p = .0001). There were no differences in rates of complications, rates of readmission, or mortality.


CONCLUSIONS
Intervention by a nurse case manager facilitated implementation of a critical pathway for patients undergoing infrainguinal bypass surgery, especially by preventing patient deviations due to intrainstitutional factors.
