Outcome | Pre-ERAS | IRR (95%CI) | Average change (95%CI) | No. of patients | Total change, d (95%CI)* |
---|---|---|---|---|---|
Primary LOS, d | 9.04 | 0.83 (0.77 to 0.90) | −1.537 (−2.079 to −0.994) | 1295 | −1990 (−2693 to −1288) |
No. of ED visits | 0.55 | 0.92 (0.66 to 1.28) | −0.044 (−0.185 to 0.152) | 1295 | −57 (−240 to 197) |
No. of specialist visits | 2.65 | 1.04 (0.84 to 1.29) | 0.106 (−0.432 to 0.756) | 1295 | 137 (−560 to 979) |
No. of GP visits | 2.1 | 0.96 (0.79 to 1.17) | −0.084 (−0.432 to 0.361) | 1295 | −109 (−560 to 467) |
No. of readmissions | 0.14 | 0.99 (0.66 to 1.48) | −0.014 (−0.047 to 0.067) | 1295 | −18 (−61 to 87) |
Readmission LOS. d | 10.1 | 0.71 (0.46 to 1.10) | −2.929 (−5.417 to 1.001) | 143 | −419 (−775 to 143) |
CI = confidence interval; ED = emergency department; ERAS = Enhanced Recovery After Surgery; GP = general practicioner; IRR = incidence rate ratio; LOS = length of stay in hospital.
Number of readmission was multiplied by the readmission LOS to get the total change in days.
