Table 9.
Variables Included in the Final Model to Assess Predictors of Surgical Intervention in ESRD Patients With Left-Sided IE
| Odds Ratio | 95% Confidence Interval | Odds Ratioa | 95% Confidence Intervala | |
|---|---|---|---|---|
| Age at diagnosis | 0.98 | 0.95–1.01 | 0.97 | 0.93–1.01 |
| Existing valve disease | 0.31 | 0.12–0.82 | 0.24 | 0.07–0.87 |
| OSH transfer | 5.4 | 2.2–13.3 | - | - |
| Coagulase-negative staphylococci | 3.8 | 1.4–10.6 | 5.6 | 1.4–22.4 |
| Valve rupture | 6.9 | 2.6–17.9 | 3.2 | 0.94–11.1 |
| New CHF | 12.1 | 3.4–43.6 | 6.8 | 1.3–34.7 |
| Any Class IIa indication | 5.9 | 2.2–15.5 | 6.2 | 1.8–21.9 |
| Any contraindication | 0.05 | 0.005–0.4 | - | - |
Fifteen patients were excluded from the final model due to missing data points; 214 patients are included in this model.
Abbreviations: CHF, congestive heart failure; ESRD, end-stage renal disease; IE, infective endocarditis; OSH, outside hospital.
aThese columns represent a sensitivity analysis excluding patients transferred from outside hospitals. In this model, when the variable “any contraindication to surgery” was included, quasi-separation of data points was observed; this variable was therefore excluded.
