Different Hospital Readmissions and Outcomes of Acute Pancreatitis
Objectives:
Although acute pancreatitis (AP) is associated with recurrent hospitalizations, the impact of different hospital readmissions (DHR) versus same hospital readmissions (SHR) on outcomes is unknown. We study the burden of DHR among readmissions after survival from AP hospitalizations.
Methods:
Among adult AP patients (Nationwide Readmissions Database), we calculated the prevalence, trends, and predictors of DHR, and its impact on mortality, hospital stay, and charges during 30- and 90-day readmissions.
Results:
From 2010 to 2014, 15% and 26% of AP hospitalizations (422,950) were readmitted in 30 and 90 days, respectively. The DHR rates were similar (26.3%, 30 days; 26.4%, 90 days) and unchanged from 2010 to 2014 (Ptrends > 0.10). The predictors of DHR were similar during both readmissions and included younger age category (18-45 years), hospital characteristics (nonteaching, small bed size, nonmicropolitan/metropolitan areas), substance abuse, comorbidities, and nonreception of cholecystectomy and pancreatectomy during index hospitalizations.During readmissions (30 and 90 days), DHR was associated with adjusted odds ratio (95% confidence interval), higher mortality (1.40 [1.19-1.64] and 1.50 [1.32-1.71]), longer hospital stay (1.3 days [1.1-1.7 days] and 1.1 days [0.9-1.3 days]), and higher charges (US $16,779 [US $13,898-US $20,254] and US $14,299 [US $12,299-US $16,623]).
Conclusions:
Targeted measures are needed toward patients at risk for DHR to curb the poor outcomes.

01:27Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
01:24Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
