The effect of hospital procedure volume of pericardiocentesis on in-hospital mortality is unknown.
The Nationwide Inpatient Sample (NIS) was used to identify patients who underwent pericardiocentesis in the United States from January 2005 to December 2010. Hospitals were separated into quartiles based on per annum pericardiocentesis volumes (group A – ≤6 pericardiocentesis/year, group B – 7-13 pericardiocentesis/year, group C −14-25 pericardiocentesis/year and group D – ≥26 pericardiocentesis/year). Propensity scores were for the comparison of the matched patient data between each quartile.
Amongst a total of 5,784 patients, the overall in-hospital mortality during the six-year study period was 15.3%. The in-hospital mortality rates for group A, group B, group C and group D were 19.5%, 14.8%, 14.6% and 12.8%, respectively (p <0.001). A linear trend in mortality improvement across quartiles was observed (p<0.001)(Figure 1).
This observational study showed that patients undergoing pericardiocentesis in high-volume centers had lower in-hospital mortality than those treated in low-volume centers. A linear trend for improvement in mortality with increasing center volume was observed.
