Length of hospital stay after percutaneous coronary interventions. 
Post-percutaneous coronary intervention (PCI) length of hospital stay (LOHS) is one of the key modifiers of hospital cost and quality assessment.  Commencing 2000, the cardiovascular services at our institution engaged in a continuous quality improvement program to reduce post-PCI LOHS.  All PCI patients were screened for potential early discharge.  An expedited discharge protocol was applied to all suitable patients.  Length of hospital stay and other outcomes were monitored daily.  Data were compiled and reported monthly and quarterly by an independent chart review and data analysis team.  Over the study period, PCI volume increased 4-fold.  Annually, 61.8% to 78.4% of the patients were rendered suitable for abbreviated LOHS.  Timely discharge of suitable candidates gradually improved from 77.6% (n = 116) discharged within 48 hours in 2000 to 95% (n = 480) discharged within 30 hours in 2006.  With the appropriate continuous quality improvement program, 30-hour post-PCI discharge is feasible in more than 95% of suitable cases.
