Poojary et al identified factors associated with 30-day readmission for a patient with ulcerative colitis. These can help to identify a patient who may benefit from more aggressive management. The authors are from Icahn School of Medicine and Memorial Sloan Kettering Cancer Center in New York City.

Patient selection: hospitalized adult with ulcerative colitis


Frequency of readmission: 10%


Reasons for readmission:

(1) complications of ulcerative colitis

(2) Clostridium difficile

(3) sepsis

(4) surgical complications

(5) complications of medical care


Predictors of readmission:

(1) depression (adjusted odds ratio 1.4)

(2) length of stay

(2a) >= 7 days (adjusted odds ratio 1.5)

(2b) 5-6 days (adjusted odds ratio 1.3)

(3) not having an endoscopy during the admission (adjusted odds ratio 1.2)


About 60% of readmissions had 1 or more predictors.

About 40% of readmissions had none of the predictors.


Factors associated with lower risk of readmission:

(1) female sex (adjusted odds ratio 0.77)

(2) self-pay status (adjusted odds ratio 0.7)

(3) non-alcoholic fatty liver disease (adjusted odds ratio 0.5)
