PURPOSE: Evidence- based practice and cost containment are vital in critical care delivery; 24/7 in- house intensivist coverage of Surgical ICU (SICU) is increasingly required. We questioned whether outcomes in cardiac surgery patients were compromised by a staffing model without intensivists or housestaff?.

METHODS: Retrospective analysis of prospectively gathered mandatory data from the New York State Cardiac Surgery Reporting System 1994 - 2009 (NYS). Annual outcomes in one center (care delivered by one group of cardiac surgeons and nurses staffing a dedicated cardiac surgery unit) are compared to NYS data.

RESULTS: 5493 patients had isolated coronary artery bypass (CABG). Mortality 1.44% (range 0- 2.78%) vs NYS (range 1.61 - 2.58). Complication incidence: Stroke 1.67 vs 1.48; Reoperation 2.14 vs 2.11; Renal 1.66 vs 1.16; Respiratory 3.84 vs 4.10; Sternal infection 1.31 vs 1.02; Sepsis 2.06 vs 0.92 and Gastrointestinal(GI) 0.6 vs 0.82. 3273 patients underwent Cardiac operations "OTHER " (than isolated CABG). Mortality 6.39% (range 1.89 - 9.79). Complications (%): Stroke 2.44; Reoperation 2.84; Renal 4.4; Respiratory 8.95; Sternal 1.31; Sepsis 4.89 and GI 1.00. Fatality rate (%) for major complication after CABG vs OTHER : Stroke 9.8/ 39; Reoperation 6 / 19; Renal 32/ 53; Respiratory 22/ 36; Sternal 11/ 21; Sepsis 27/ 45; GI 53/ 45. Hospital stay (LOS) trended longer (range 6.8-9.6 days); Excluding patients staying > 15 days (3-12%) increased LOS by 1 day (5.8 - 6.7). Fewer than 5% of deaths were classified "Postoperative" and "Avoidable". Extending our SICU coverage 24/7 costs $773 600 annually.

CONCLUSION: Mortality, risk adjusted mortality, complication rates and lethality were within state average/ range consistently 1994-2006. Unpredicted life-threatening postoperative emergencies were very rare. Occasional SICU emergency support for Cardiac Surgery patients did not affect individual outcomes. Patients with complications consume disproportionate resources.

CLINICAL IMPLICATIONS: A model of care for Cardiac Surgery patients without intensivists is supported by the data but depends on expertise and dedication of surgeons and nurses and attention to evidence based practices.
