A case-control study was used to collect patients who developed VTE during hospitalization in the Department of Respiratory Medicine at Peking University Third Hospital Hospital from January 2015 to December 2020 as the case group, and 2-fold patients who did not develop VTE matched to the case group (age, sex, ADL score, diagnosis, and length of hospitalization) as the control group. The general status of the patients was also assessed using the Padua risk model, the Caprini risk model, and the VTE risk assessment scale for medical patients mentioned in the 2018 edition of the Guidelines for the diagnosis, treatment, and prevention of pulmonary thromboembolism, and the relevant items involved in the assessment form were obtained by reviewing the cases.
To compare the predictive effectiveness of the Caprini risk assessment model, the Padua risk assessment model and the VTE risk assessment in medical patients mentioned in the 2018 edition of the Guidelines for the diagnosis, treatment and prevention of pulmonary thromboembolism on the risk of concomitant VTE in respiratory inpatients to provide a basis for clinical VTE assessment and treatment.
