The number of comorbidities as an important cofactor to ASA class in predicting postoperative outcome: An international multicentre cohort study.

Background: Multimorbidity is a growing burden in our ageing society and is associated with perioperative morbidity and mortality. Despite several modifications to the ASA physical status classification, multimorbidity as such is still not considered. Thus, the aim of this study was to quantify the burden of comorbidities in perioperative patients and to assess, independent of ASA class, its potential influence on perioperative outcome.

Bibliometric analysis of academic journal recommendations and requirements for surgical and anesthesiologic adverse events reporting.

Background: Standards for reporting surgical adverse events (AEs) vary widely within the scientific literature. Failure to adequately capture AEs hinders efforts to measure the safety of healthcare delivery and improve the quality of care. The aim of the present study is to assess the prevalence and typology of perioperative AE reporting guidelines among surgery and anesthesiology journals.

Appraisal of Intraoperative Adverse Events to Improve Postoperative Care.

Background: Intraoperative adverse events (iAEs) are associated with adverse postoperative outcomes and cause a significant healthcare burden. However, a critical appraisal of iAEs is lacking. Considering the details of iAEs could benefit postoperative care.

Discrepancy in Reporting of Perioperative Complications: A Retrospective Observational Study.

Objective: To assess the discrepancy between perioperative complications, prospectively recorded during a cohort study versus retrospectively from health records.

Background: Perioperative adverse events are relevant for patient outcome, but incomplete reporting is common.

Methods: Two physicians independently recorded all intraoperative adverse events according to ClassIntra and all postoperative complications according to the Clavien-Dindo classification based on all available health records.
