Background and Goals: Ulcerative colitis (UC) readmissions to the hospital pose a burden to patients and health care systems. Preventing readmissions is important for the quality of care and quality of life of patients with UC. We aimed to identify the incidence of 30 and 90-day readmissions and its predictors in patients with UC. Study: Retrospective review of the 2018 National Readmission Database (NRD) of adult patients readmitted after an index admission (IA) of UC. ICD-10CM/PCS codes were used to identify patients with UC, other comorbidities, and procedures. We identified the most common causes for readmission and independent risk factors for readmission were identified using Cox regression analysis. Results: The 30 and 90-day readmission rates for UC in 2018 were 16.6% and 28.3%. In-hospital mortality and mean length of stay were higher in patients readmitted within both 30 and 90 days. Independent predictors of 30-day readmission were higher Charlson Comorbidity Index (CCI), undergoing ileostomy, increasing length of stay, malnutrition and opioid use disorder at IA. In the 90-day readmission cohort, independent predictors were CCI score of 2 or ≥3, developing shock, admission to large bed size hospitals, undergoing colectomy, increasing length of stay and opioid use disorder at IA. The number one readmission cause at 30 and 90 days was sepsis of unspecified organism. Conclusion: Readmission is associated with higher mortality and is associated with risk factors such as malnutrition, undergoing ileostomy during IA and opioid use disorder. Readmissions in UC continue to pose a high burden to patients and our health care system.

ABSTRACT Autoimmune pancreatitis (AIP) and pancreatic cancer share clinical and radiological features, making biopsy the only definitive way of differentiating them. Numerous reports in the literature describe the co-occurrence of AIP and pancreatic cancer either in a synchronous manner or metachronous manner raising the question of which condition predisposes to the other and whether a causal relationship exists between them. Studies suggest shared mechanisms, including K-ras mutations and tumor suppressor gene silencing. This case highlights the importance of long-term surveillance in AIP patients to monitor for malignancy.
