BISAP Score for Pancreatitis Mortality


Defined as disorientation, lethargy, somnolence, coma or stupor

BISAP Score calculator

The Bedside Index for Severity in Acute Pancreatitis (BISAP) Score has been officially designed to signify those patients who have chance mortality or extreme disease during the initial period of acute pancreatitis.

The physicians and doctors have carried out the analysis of the BISAP scoring criteria to gauge the correctness of the system. The analysis was needed so that the doctors can check if the Scoring system is able to foretell the rate of mortality and extreme acute pancreatitis.

Research on BISAP Score

The medical experts have taken into consideration the digital archives of libraries, such as Cochrane, Pubmed, and Embase in order to signify the studies making use of BISAP Score in order to forecast the SAP or death case.

The Diagnostic Odds Ratio (DOR) reactivity, particularity, probability were computed from every research and were equated with the primitive scoring criterion.  The 12 groups from the 10 types of research became a part of it. The total reactivity of a BISAP score was greater or equal to 3, for the death it was 0.56 with the particularity at 0.91.

There are ratios that were both positive and negative ratios. As far as the result of SAP was concerned, the mutual reactivity was 0.51 and the particularity was 0.91. The Mutual positive and negative ratios were 7.23 and 0.56.

Why BISAP Score is recommended?

The BISAP Score enables the early assessment of those patients who are likely to die in the hospital. The scoring criteria created with the help of data retrieved. It was done from more than 17,000 matters of acute pancreatitis from over 200 hospitals during the period starting from 2000 and 2001. The scoring criteria have been authenticated in an extra 18,000 matters from more than 176 hospitals between the years 2004 and 2005.

The exactness of the scoring criteria for forecasting the death rate was computed by the area below the receiver operating characteristic curve or the AUC and by comparing it with the Acute Physiology and Chronic Health Examination II or known as APACHE.

The five varieties computed within the initial 24hours forecasted the death rate in the hospital. Those five varieties include the following:

  • BUN or Blood Urea nitrogen >25 mg/dl
  • The inflammatory response is systemic
  • Mental impairment
  • Existence of pleural effusion
  • Age above 60 years

In the authenticating group, the BISAP AUC was 82% equating with the APACHE II which is 83%. If one analyzes from a critical point of view. The APACHE II score, the Ranson Criteria, and BISAP score, when compared together, demonstrated that reactivity and lesser particularity were present in the Ranson and APACHE II.
