Because not all patients are candidates for early discharge, in the present study our aim was to determine factors that prolong LOS.\n          <\/jats:p>\n          <jats:p>\n            <jats:italic>Methods and Results<\/jats:italic>\n            In 194 consecutive patients undergoing CABG procedures, LOS was &gt;7 days in 37%. Stepwise multiple regression procedures and \u03c7\n            <jats:sup>2<\/jats:sup>\n            testing were used to determine what factors prolonged LOS for &gt;7 days. Preoperative factors that significantly (\n            <jats:italic>P<\/jats:italic>\n            &lt;.05) prolonged LOS included repeat CABG, CABG plus valve surgery, congestive heart failure, preoperative coronary care unit stay, renal failure, and insulin-dependent diabetes mellitus. Patients with at least one risk factor had a significantly higher incidence of LOS of &gt;7 days (47% versus 17%;\n            <jats:italic>P<\/jats:italic>\n            &lt;.001). Significant (\n            <jats:italic>P<\/jats:italic>\n            &lt;.05) postoperative factors prolonging LOS included arrhythmias, respiratory insufficiency, pneumonia, and wound infection.
