The impacts of electronic commerce on auditing practices: an auditing process model for evidence collection and validation

[[abstract]]The main purposes of this paper are twofold. First, the paper identifies and discusses the potential impacts of electronic commerce on auditing practices in the emerging paperless on‐line transaction environment. Second, it provides two auditing process models that incorporate modern network security techniques and show how an audit can be conducted in an EC environment. A periodical auditing process model (PAPM) is proposed to demonstrate how secure electronic technologies can be used to facilitate the auditor's evidence collection and validation process for annual and semi‐annual audits. We also present a continuous auditing process model (CAPM) which extends the functions of PAPM for continuous auditing. In CAPM, a real‐time transaction monitoring system is used to link to firms' accounting information systems for assisting the auditor to detect abnormal activities and generate exception reports on a continuous basis. The CAPM approach intends not only to ensure integrity and effectiveness of the entire accounting system, but also to guarantee the correctness and usefulness of the constantly generated financial statements for public dissemination. The main contribution of this paper is that it illustrates a conceptual framework which shows the feasibility of continuously auditing electronic transactions in the EC environment.[[journaltype]]國

Preoperative nasopharyngeal swab testing and postoperative pulmonary complications in patients undergoing elective surgery during the SARS-CoV-2 pandemic.

BACKGROUND: Surgical services are preparing to scale up in areas affected by COVID-19. This study aimed to evaluate the association between preoperative SARS-CoV-2 testing and postoperative pulmonary complications in patients undergoing elective cancer surgery. METHODS: This international cohort study included adult patients undergoing elective surgery for cancer in areas affected by SARS-CoV-2 up to 19 April 2020. Patients suspected of SARS-CoV-2 infection before operation were excluded. The primary outcome measure was postoperative pulmonary complications at 30 days after surgery. Preoperative testing strategies were adjusted for confounding using mixed-effects models. RESULTS: Of 8784 patients (432 hospitals, 53 countries), 2303 patients (26.2 per cent) underwent preoperative testing: 1458 (16.6 per cent) had a swab test, 521 (5.9 per cent) CT only, and 324 (3.7 per cent) swab and CT. Pulmonary complications occurred in 3.9 per cent, whereas SARS-CoV-2 infection was confirmed in 2.6 per cent. After risk adjustment, having at least one negative preoperative nasopharyngeal swab test (adjusted odds ratio 0.68, 95 per cent confidence interval 0.68 to 0.98; P = 0.040) was associated with a lower rate of pulmonary complications. Swab testing was beneficial before major surgery and in areas with a high 14-day SARS-CoV-2 case notification rate, but not before minor surgery or in low-risk areas. To prevent one pulmonary complication, the number needed to swab test before major or minor surgery was 18 and 48 respectively in high-risk areas, and 73 and 387 in low-risk areas. CONCLUSION: Preoperative nasopharyngeal swab testing was beneficial before major surgery and in high SARS-CoV-2 risk areas. There was no proven benefit of swab testing before minor surgery in low-risk areas
