Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

[EX Q]: The aim of this study was to assess the effect of the implementation of evidence-based guidelines and subsequent feedback to surgeons in the management of acute pancreatitis.', 'An evidence-based Pancreatitis Proforma was developed. Data were prospectively recorded (01/06/2005-30/09/2007). Audit feedback (AFB) was performed at 9 months. A final analysis was performed comparing outcomes pre- and post-audit feedback.', '372 patients were included. Median age (range) was 57 (12-96) years. 168 (45.2%) patients were admitted pre-AFB. Post-AFB, there was a significant increase in the number of patients whose diagnosis was made within 48 hours (135/168 (80.4%) vs 189/204 (92.6%), p<0.001) and who underwent definitive treatment for mild biliary pancreatitis (33/61 (54.1%) vs 56/70 (80.0%), p=0.002). Post-AFB there was also a significant reduction in the number of computed tomography (CT) scans performed for patients with mild acute pancreatitis (23/85 (27.1%) vs 13/99 (13.1%), p=0.018). Mortality (9/168 (5.4%) vs 3/204 (1.4%), p=0.040) also decreased. On multivariate analysis, AFB was an independent factor for change in the use of CT scans (p=0.015) and management of patients with mild biliary pancreatitis (p=0.039).
[EX A]: Is closing the audit loop necessary to achieve compliance with evidence-based guidelines in the management of acute pancreatitis?

[EX Q]: Radiofrequency applications to the posteroseptal region can ablate the atrioventricular accessory pathway residing in this area. In conjunction with the adjacent anatomic structures, however, ablative lesions which do not effectively ablate the accessory pathway could markedly alter retrograde atrial activation sequence and confound interpretation of further mapping of an accessory pathway.', 'Electrophysiologic studies, endocardial activation mapping and radiofrequency catheter ablation were undertaken in three patients with recurrent supraventricular tachycardia. Patients were initially thought to have a single posteroseptal accessory pathway; earliest ventrioatrial activation during tachycardias and during ventricular pacing was at the coronary sinus ostium, but initial radiofrequency applications were unsuccessful to ablate the pathway. After initial radiofrequency applications to the posteroseptal region, the earliest retrograde atrial activation changed to the right atrial free wall in two patients. Additional radiofrequency application to the posteroseptal area was able to ablate the single posteroseptal accessory pathway in one patient. Radiofrequency application to the right atrial free wall was required to stop tachycardia initiation in other patient. The third patient was suspected of having a slow-slow atrioventricular nodal reentry tachycardia. Radiofrequency application to the posteroseptal area changed the earliest retrograde atrial activation to the distal coronary sinus recording site, mimicking an accessory pathway at the left atrial free wall. Radiofrequency application to the anteroseptum was able to ablate the concealed accessory pathway.

[EX Q]: The objective of this study was to determine if delivery of wound care instruction pre-Mohs micrographic surgery versus the typical, post-Mohs surgery would allow for greater patient retention.', 'A non-blinded, randomized, controlled trial receiving institutional review board exemption from Michigan State University was conducted over a three-month period. Patients scheduled for Mohs surgery on 13 selected days were randomized into pre- versus post-procedure groups to receive wound care education.', 'This study was conducted at a dermatology practice in Saint Joseph, Michigan.', 'Fifty cognitive and literate patients greater than 18 years of age were evaluated in this study.', "PARTICIPANTS' ability to recall instructions delivered by a Mohs surgeon in the form of digital media was assessed by a 10-question, multiple-choice exam. Additional analyses were conducted on patient's disposition around medical professionals, past experience with Mohs surgery, preference for digital media versus human instruction, and desire for home access.", 'Pre- (n=24; score=7714%) versus post-(n=26; 8311%) procedure education displayed no significant difference (p=0.13) in overall questionnaire performance. Seventy-four percent of participants preferred video delivery as opposed to provider instruction. Thirty-four percent reported being intimidated by healthcare workers. Participant performance showed no significant change (p=0.78) with previous exposure (7919%) to Mohs surgery versus a first-time encounter (8011%).
