Management of acute pancreatitis: a comparative audit of clinical practice against the recommendations of the british society of gastroenterology
AIMS: In 1998 the British Society of Gastroenterology (BSG) published national guidelines for the management of acute pancreatitis (AP) in an attempt to improve diagnosis and reduce mortality rates. A comparative audit was undertaken of the management of AP against the BSG recommendations. METHODS: A retrospective analysis of 53 patients (median age 61 (range 24-95) years) admitted with AP during 1998 was undertaken and a comparison was made with the BSG guidelines. RESULTS: Some 70 per cent (n = 37) of the patients were admitted with mild AP and 30 per cent (n = 16) with severe AP. The BSG recommendations are shown in parentheses in the following text. The overall mortality rate was 17 per cent (less than 10 per cent), zero in mild AP and 56 per cent in patients with severe AP (less than 30 per cent). A correct diagnosis of AP was made within 48 h of admission in all patients (100 per cent). Severity stratification within 48 h using the Glasgow criteria and C-reactive protein (CRP) level, as suggested by the BSG, was done in approximately 80 per cent of patients. Table 1. CRP was measured in 51 per cent of the patients within the first 4 days (100 per cent) and at the end of the first week (100 per cent). Gallstones and alcohol counted for 72 per cent of causes of AP and the aetiology was determined in 77 per cent (75-80 per cent). All patients with severe AP were managed in a high-dependency or intensive therapy unit with central venous pressure monitoring and prophylactic intravenous antibiotics, and underwent dynamic computed tomography within 3-10 days of admission (100 per cent). Some 86 per cent of patients with suspected common bile duct (CBD) stones (jaundice, deranged liver function tests, dilated CBD) underwent endoscopic retrograde cholangiopancreatography with or without duct drainage and clearance. CONCLUSIONS: Management of AP closely mirrors the BSG guidelines, but fails to fully address severity stratification with respect to LDH, CRP and PaO2 at 48 h. A thorough analysis of patients with severe AP (i.e. extent of pancreatic necrosis, onset of infection) has been undertaken to explain the mortality rate and it is proposed to prospectively audit admissions with AP in 1999 in order to close the audit loop.
