Abstract:

Introduction
Acute neurological conditions including ischemic and hemorrhagic stroke are the third leading cause of mortality in Canada, and the incidence of these conditions is increasing as the population ages1. Guidelines recommend admission of patients with stroke to dedicated Stroke Units; neurointensive care units are recognized to improve outcomes including decreased mortality and length of hospital stay (LOS) for patients with critical neurological conditions2–7 . In particular, closed units staffed by neurohospitalists or neurointensivists who work closely with Neurology and Neurosurgery have been shown to improve outcomes8,9.

Intensive care unit admissions have increased 12% over the past 6 years, and novel ways to provide high-quality neurocritical care but reduce costs are required10. Small studies have demonstrated the safety of admitting patients with intracranial hemorrhage or after neurosurgical procedures to step-down units, but few studies have analyzed both cost and safety outcomes of intermediate-level units11,12

Objectives
This health records review assessed clinical and cost-related outcomes in an intermediate-level Neurosciences Acute Care Unit (NACU) before and after the addition of a neurointensivist to the unit’s multidisciplinary team.
 
Methods
This was a retrospective study of prospectively collected data from a 16-bed NACU of a Canadian hospital. Starting in October 2011, a closed model of NACU care was adopted including full-time day coverage by a neurointensivist. Data were obtained for all patients admitted to the NACU between October 2010 and September 2013, or one year prior to and two years after the intervention. Outcomes assessed included demographic information, time to admission, and length of stay in the NACU and hospital. Safety outcomes included mortality and readmission rates. Descriptive and analytic statistics were calculated, and the Kruskal-Wallis one-way analysis of variance test was used to detect differences in the LOS between groups; for all other outcomes, a chi-square test was used. For both pre- and post-groups, individual and total patient costs were calculated from NACU and hospital LOS, based on per-day cost estimates (NACU = $1262/day, ward bed = $1128/day). Statistical significance for costs was measured using bootstrapping technique for 95% confidence intervals. A sensitivity analysis was performed to demonstrate cost savings by increasing or decreasing NACU LOS by one day.
 
Results
A total 2931 patients were discharged from NACU over the study period (822 prior to the addition of a neurointensivist and 2109 post). Patient demographics were similar, as displayed in Table 1. The mean age of patients admitted was 59.5 years +/- 18; 53% of patients were male. The most common reasons for admission were CNS tumor (27.6%), ischemic stroke (27%), and subarachnoid hemorrhage (11%). Following the introduction of a neurointensivist, there was a significant reduction in LOS both in NACU and on the ward (Table 2). There were no significant differences in rates of readmission or mortality. The addition of a neurointensivist produced an average individual cost savings of $1262 in NACU and $3518 for each patient’s total hospital stay (Table 3).

Conclusion
A closed-unit model of intermediate-level neurointensive care staffed by neurointensivists is safe, decreases patient LOS, and produces cost savings in a system that will be increasingly strained to provide quality neurocritical care.
