Patient selection: adult on maintenance hemodialysis
Outcome: 30-day readmission
Predictors of readmission (model 2 using discharge data):
(1) malignancy (odds ratio 2.1)
(2) >=3 hospital admissions in the prior year (odds ratio 2.0)
(3) >= 10 outpatient medications on admission (odds ratio 1.7)
(4) catheter vascular access (odds ratio 1.8)
(5) outpatient dialysis at a non-university affiliated dialysis facility (odds ratio 3.6)
(6) intradialytic hypotension (odds ratio 3.1)
(7) discharge over the weekend (odds ratio 1.8)
(8) serum albumin < 3.3 g/dL (odds ratio 4.3, any time during admission)
Reducing the number of medications between admission and discharge is associated with a lower readmission rate (odds ratio 0.20).
