At this time, the effect of hospital pericardiotomy procedure volume on in–hospital mortality is unknown.
The Nationwide Inpatient Sample (NIS) was used to identify patients who underwent pericardiotomy in the United States from January 2005 to December 2010. Hospitals were separated into quartiles based on per annum pericardiotomy volume (group A – ≤11 pericardiotomies/year, group B – 12–18 pericardiotomies/year, group C −19–30 pericardiotomies/year and group D – ≥31 pericardiotomies/year). Propensity scores were used to compare matched patient data between each quartile.
Amongst a total of 9,884 patients, the overall in–hospital mortality was 10.0%. The in–hospital mortality for group A, group B, group C and group D were 10.1%, 10.3%, 8.8% and 11.1%, respectively (p=0.055 for between–group significance, p=0.619 for significance of trend) (Figure 1).
This observational study demonstrates that in–hospital mortality after surgical pericardiotomy is not significantly different between high–volume centers and low–volume centers.
