Table 2 The rates of unplanned readmissions and 30-days Emergency visits after index discharge the 2 groups of patients

From: Applicability of a previously validated readmission predictive index in medical patients in Singapore: a retrospective study

 

LACE < 10, n=107495

LACE ≥10, n=20055

Unadjusted OR (95% CI)

Adjusted OR ( 95% CI)

30-days unplanned readmission, %

4.87

18.43*

4.37 (4.18-4.57)*

4.88 (4.57-5.22)*

90-days unplanned readmission, %

7.91

29.22*

4.81 (4.61-5.00)*

5.40 (5.11-5.72)*

30-days Emergency visit, %

11.64

27.42*

2.87 (2.77-2.98)*

2.97 (2.81-3.13)*

  1. P value for unadjusted OR was calculated using Chi-Square test; P value for adjusted OR was calculated using Logistic regression with adjustment for age group, gender, ethnicity, year of discharge, ICU admission and admission class. *p<0.001.
  2. Hosmer and Lemeshow test for 30-day all-cause unscheduled readmission, x2 = 12.7, df = 8, P = 0.122. C- statistic 0.70; P < 0.001.
