Sensitivity of Biochemical and Imaging Findings for the Diagnosis of Acute Pancreatitis in Children.

ABSTRACT: OBJECTIVE:To determine the diagnostic sensitivity of serum biomarkers and imaging in the diagnosis of acute pancreatitis in children. STUDY DESIGN:This was a cross-sectional analysis of prospective registry data for children (age <21 years) whose first documented attack of acute pancreatitis occurred between March 2013 and October 2016 at a single-institution, tertiary care center. Main outcome was sensitivity of serum biomarkers and of imaging modalities, measured via descriptive statistics. RESULTS:In total, 112 children met the criteria for acute pancreatitis; 57 (51%) were male with a median age of 13.4 years (IQR 9.3-15.8 years). Serum amylase and lipase levels were obtained in 85 (76%) and 112 (100%) patients, respectively. Imaging was performed in 98 (88%) patients, with abdominal ultrasound (US) performed in 84 (75%) and computed tomography and/or magnetic resonance imaging performed in 46 (41%) patients. Fifty-three (47%) patients met all 3 diagnostic criteria (clinical, biochemical, and imaging) for acute pancreatitis. Laboratory testing had a 5.4% false-negative rate for acute pancreatitis. Serum lipase alone and amylase alone were 95% (95% CI 89%-98%) and 39% (95% CI 28%-50%) sensitive for acute pancreatitis, respectively. Imaging (any modality) was 61% sensitive (95% CI 51%-71%) for acute pancreatitis with a 34% false-negative rate. US alone was 52% (95% CI 41%-63%) sensitive for acute pancreatitis and computed tomography/magnetic resonance imaging was 78% (95% CI 63%-89%) sensitive. Combinations of diagnostic criteria performed no better than laboratory testing alone. CONCLUSIONS:The majority of children coming to medical attention with their first documented occurrence of acute pancreatitis have characteristic symptoms. Serum lipase is highly sensitive for the diagnosis of acute pancreatitis, and serum amylase is moderately sensitive. Imaging, particularly US, is only moderately sensitive, and cross-sectional imaging provides greater sensitivity for diagnosing acute pancreatitis.

Project description:OBJECTIVES:The Pancreatitis Activity Scoring System (PASS) has been derived by an international group of experts via a modified Delphi process. Our aim was to perform an external validation study to assess for concordance of the PASS score with high face validity clinical outcomes and determine specific meaningful thresholds to assist in application of this scoring system in a large prospectively ascertained cohort. METHODS:We analyzed data from a prospective cohort study of consecutive patients admitted to the Los Angeles County Hospital between March 2015 and March 2017. Patients were identified using an emergency department paging system and electronic alert system. Comprehensive characterization included substance use history, pancreatitis etiology, biochemical profile, and detailed clinical course. We calculated the PASS score at admission, discharge, and at 12?h increments during the hospitalization. We performed several analyses to assess the relationship between the PASS score and outcomes at various points during hospitalization as well as following discharge. Using multivariable logistic regression analysis, we assessed the relationship between admission PASS score and risk of severe pancreatitis. PASS score performance was compared to established systems used to predict severe pancreatitis. Additional inpatient outcomes assessed included local complications, length of stay, development of systemic inflammatory response syndrome (SIRS), and intensive care unit (ICU) admission. We also assessed whether the PASS score at discharge was associated with early readmission (re-hospitalization for pancreatitis symptoms and complications within 30 days of discharge). RESULTS:A total of 439 patients were enrolled, their mean age was 42 (±15) years, and 53% were male. Admission PASS score >140 was associated with moderately severe and severe pancreatitis (OR 3.5 [95% CI 2.0, 6.3]), ICU admission (OR 4.9 [2.5, 9.4]), local complications (3.0 [1.6, 5.7]), and development of SIRS (OR 2.9 [1.8, 4.5]) as well as prolongation of hospitalization by a mean of 1.5 (1.3-1.7) days. For the prediction of moderately severe/severe pancreatitis, the PASS score (AUC?=?0.71) was comparable to the more established Ranson's (AUC?=?0.63), Glasgow (AUC?=?0.72), Panc3 (AUC?=?0.57), and HAPS (AUC?=?0.54) scoring systems. Discharge PASS score >60 was associated with early readmission (OR 5.0 [2.4, 10.7]). CONCLUSIONS:The PASS score is associated with important clinical outcomes in acute pancreatitis. The ability of the score to forecast important clinical events at different points in the disease course suggests that it is a valid measure of activity in patients with acute pancreatitis.

Project description:BACKGROUND:Literature has suggested that imaging is over-utilized in the diagnosis of pancreatitis. If the diagnosis of acute pancreatitis (AP) is established with abdominal pain and increased serum amylase or lipase activity without systemic signs of severe disease, computed tomography (CT) imaging may not be necessary. We hypothesize that among patients with uncomplicated acute pancreatitis (AUP), there is a significant number of unwarranted CT imaging studies. This imposes increased expenditure and cost in our healthcare system and does not improve hospital stay or management of AUP. AIM:To assess the overutilization and associated cost of CT imaging among patients meeting diagnostic criteria for AUP. METHODS:In this Institutional Review Board-approved retrospective, single-center study, we identified all adult patients admitted with AP from January 1, 2012 through October 1, 2017. Patients were identified via International Classification of Diseases (ICD-9) code for AP (577.0) and ICD-10 codes for different etiological AP (K85.9 unspecified, K85.0 idiopathic, K85.1 biliary, K85.2 alcohol-induced, K85.3 drug-induced, and K85.8 other). Diagnosis was confirmed by chart review using established non-imaging diagnostic criteria (presence of typical abdominal pain and elevated lipase or amylase greater than 3 times upper limit of normal). Ranson criteria and BISAP scores on presentation were calculated and patients that met scores less than or equal to 2 for both were included to suggest AUP. The utilization and cost of imaging in these patients were recorded. RESULTS:Between January 2012 and October 2017, 1305 patients presented to the emergency department with AP, and 405 patients (31%) met our inclusion criteria for AUP (201 males, 204 females; mean age 49 years, range 18-98). Of those, 210 patients (51.85%) underwent CT imaging. One patient (0.47%) had evidence of pancreatic necrosis, one patient had cyst formation (0.47%), and the remaining 208 patients (99.05%) had either normal CT scan imaging or findings consistent with mild AP without necrosis. The average cost of CT scan imaging was $4510 with a total cost of $947056. Median length of hospitalization stay was 3 d among both groups. Combining Ranson's Criteria and BISAP score identified AUP in our patient population with an accuracy of 99.5%. CONCLUSION:CT imaging is unnecessary when AUP is diagnosed clinically and biochemically. Reducing overuse of diagnostic CT scans will decrease healthcare expenditure and radiation exposure to patients.
