Our objectives were to validate diagnoses of AP and to identify an algorithm using additional data to enhance the identification of AP cases in different data sources.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We randomly sampled 550 persons with an AP diagnosis from inpatient data or outpatient or emergency department diagnoses immediately preceding a hospitalization and 150 negative controls with a differential diagnosis (cholangitis or cholecystitis). We conducted an EMR review to confirm cases of AP and used logistic regression to develop EMR\u2010based and claims\u2010based algorithms to identify confirmed AP cases with variables typically available in electronic data sources. Algorithm performance was assessed using the C statistic, sensitivity, specificity, and positive and negative predictive value.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Of the 550 patients with an AP diagnosis, 467 (84.9%) were confirmed cases. An AP diagnosis alone had high sensitivity (98.9%), modest specificity (63.6%), and a C statistic of 0.813.
