Objectives

Indications for the use of stents are evolving and their optimal place in therapy remains to be defined. The objective was to compare the 1-year clinical and economic outcomes of percutaneous transluminal coronary agioplasty (PTCA) with and without the use of stents.

Methods

This retrospective database analysis was conducted using data from 60 US academic medical centers in 1996 and 1997. Outcomes of interest included in-hospital mortality (both on sentinel and readmission visits), readmission rates, revascularization procedures, length of stay, and the cost of sentinel and readmission hospitalization.

Results

A total of 27,020 patients either did (n = 13,254) or did not (n = 13,766) receive coronary stents in conjunction with PTCA. The median cost of hospitalization for the stent group was about $1,409 higher (mean, $1,200) than the no-stent group and the length of stay was similar (4.3 days vs. 4.5 days, respectively, P = .2628). Mortality rates on readmission (0.9% stent vs. 0.8% no-stent, P = NS) did not differ. However, patients in the stent group had better mortality rates compared to the no-stent group during the sentinel visit (1.7% vs. 2.7%, P .001). Stent use was not associated with a significantly lower risk of a revascularization procedure on readmission to the same institution (OR 0.95, 95% CI 0.87–1.04, P = .28).

Conclusion

Stents were associated with a 1% decrease of inpatient mortality during the sentinel visit without impacting length of stay or readmission rates. This advantage was associated with a $1,409 higher median cost of hospitalization in the stent group.
