TABLE 4.

Adjusted predicted probabilities^* and 95% CIs of 1-yr mortality after colectomy for cancer, by 30-day readmission status and cancer stage.

	% Mortality in Non-Readmitted Patients (n=37,686)	% Mortality in Readmitted Patients (n=4,662)
All Patients (n=42,348)	7.4 (7.1—7.7)	16.3 (15.2—17.3)
Stage 1 Patients (n=10,181)	3.0 (2.6—3.3)	9.6 (7.9—11.2)
Stage 2 Patients (n=18,817)	5.9 (5.5—6.3)	14.1 (12.7—15.6)
Stage 3 Patients (n=13,350)	15.1 (14.3—15.8)	26.1 (23.8—28.3)

^*Predicted probabilities are adjusted for age, gender, race/ethnicity, marital status, census tract median household income and percent of non-high school graduates, SEER registry, rural/urban residence location, hospitalization in the year before surgery, Hierarchical Condition Categories (HCC) comorbidity score, tumor stage and grade, emergent admission, obstruction, perforation, year of surgery, hospital and surgeon procedure volume, laparoscopic vs. open resection, length of stay, blood transfusion, ostomy, in-hospital complication, discharge destination, and receipt of chemotherapy.

CI indicates confidence interval.
