Insights
Implementing a pediatric cardiovascular step-down unit (CVSDU) significantly reduced length of stay and rapid response events for children with congenital heart disease. This change improved care processes without increasing adverse events.
Area of Science:
- Pediatric Cardiology
- Healthcare Quality Improvement
- Hospital Operations
Background:
- The Joint Commission's safety goals prompted hospitals to improve clinical deterioration response.
- Intermediate-care units were introduced for non-ICU patients.
- The impact of pediatric cardiovascular step-down units (CVSDU) on care outcomes was unstudied.
Purpose of the Study:
- To evaluate the effect of establishing a CVSDU on process-of-care outcomes.
- To compare outcomes before and after CVSDU implementation in pediatric congenital heart disease patients.
Main Methods:
- Retrospective cohort study of 1415 pediatric congenital heart disease patients.
- Compared outcomes 1 year before and 1 year after CVSDU implementation.
- Used non-cardiac tracheostomy/ventilator-dependent patients as controls (n=606).
Main Results:
- CVSDU patients had significantly decreased total length of stay (LOS) (7.0 vs 5.4 days) and non-ICU LOS (3.5 vs 3.0 days).
- Rapid response team/code blue rate per 1000 non-ICU patient days decreased significantly (11.2 vs 7.0).
- No significant outcome differences were observed in the control group.
Conclusions:
- Establishing a CVSDU was associated with reduced LOS for pediatric congenital heart disease patients.
- CVSDU implementation correlated with lower rates of rapid response and code blue events.
- The changes improved care processes without negative impacts on control patient groups.
Background:
The Joint Commission's 2009 National Patient Safety Goals aimed to improve identification of and response to clinical deterioration in hospital-ward patients. Some hospitals implemented intermediate-care units for patients without intensive care-level support needs. No studies have evaluated what effect changes associated with a move to a pediatric cardiovascular step-down unit (CVSDU) has on process-of-care outcomes.
Methods:
A retrospective cohort study comparing process-of-care outcomes in units caring for children with congenital heart disease (n=1415) 1 year before (July 1, 2010-June 30, 2011) and 1 year after (August 1, 2011-July 30, 2012) implementation of a CVSDU following the move to a new hospital building. Units caring for noncardiac tracheostomy and/or ventilator-dependent patients were used as controls (n=606). Primary outcomes included length of stay (LOS) and transfers to higher levels of care. Secondary outcomes included rapid response team, cardiopulmonary arrest, and code blue rates. Mann-Whitney U and z tests were used for all analyses.
Results:
When compared with a medical-surgical unit, cardiac patients admitted to a CVSDU had a significantly decreased total LOS (median 7.0 vs 5.4 days, P=.03), non-ICU LOS (median 3.5 vs 3.0 days, P=.006), and rapid response team/code blue rate per 1000 non-ICU patient days (11.2 vs 7.0, P=.04). No significant differences in primary or secondary outcomes were seen within the control group.
Conclusions:
Changes associated with a new CVSDU were associated with decreased LOS and lower rates of rapid response and code blue events for patients with congenital heart disease.
