Descriptive and Risk Factors Analysis of All-cause Postoperative Death in Patients Undergoing Elective Surgery
An observational study of Postoperative Death, run by Huazhong University of Science and Technology at 5 sites in China.
Trial summary
The investigators are aimed to develop and externally validate a prediction model of clinical risk factors that quantifies postoperative death after elective surgery. We identify all patients treated with elective surgery, between 2000 and 2020, within the Wuhan Union hospital and all collaborators. Read more about this study

About this study
Official title: Descriptive and Risk Factors Analysis of All-cause Postoperative Death in Patients Undergoing Emergency Surgery
The investigators are aimed to develop and externally validate a prediction model of clinical risk factors that quantifies postoperative death after elective surgery.
We identify all patients treated with elective surgery, between 2000 and 2020, within the Wuhan Union hospital and all collaborators. The surgical patient cohort will be matched with the National Death database to determine the patient's postoperative death data.
60% patients were randomly selected to the development cohort. Logistic regression analysis for prediction of postoperative death adjusted for different covariates. The model was externally validated in the remaining 40% patients.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Postoperative Death (time frame: The mortality within 5 years after the elective surgery). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Jul 2021.
