Abstract 【Objective】 To investigate the value of erythrocyte distribution width (RDW) and ratio of RDW/serum calcium in evaluating the condition and prognosis of patients with acute pancreatitis. 【Methods】 A total of 153 patients with AP in our hospital were selected as the research subjects. The clinical data of all patients were analyzed and the risk factors affecting the severity and poor prognosis of AP patients were analyzed. The value of RDW and ratio of RDW/serum calcium in evaluating the condition and prognosis of AP patients was explored. 【Results】 Univariate and logistic regression analysis showed that the AP patients with RDW>15.56%, BUN>23.52 mg/dL and ratio of RDW / serum calcium>1.79 were more severe. The AUC of AP patients diagnosed by the ratio of RDW / serum calcium was greater than that of AP patients diagnosed by RDW and BUN, but the difference was not statistically significant (P>0.05).Univariate and logistic regression analysis also showed that the prognosis of AP patients with RDW>15.56%, APACHE Ⅱ>14.06, lactate >2.40mg/dL and ratio of RDW / serum calcium>1.79 was worse. The prognosis of AUC in patients with AP diagnosed by RDW/serum calcium was lower than that of APACHE Ⅱ, while it was higher than that of RDW and lactic acid, but the differences were not statistically significant (P>0.05). 【Conclusion】 RDW/ serum calcium is an independent influence factor of AP patients' worsening condition and poor prognosis. RDW/ serum calcium can be used as a reference index for evaluating the condition and prognosis of AP patients.
