Abstract: Aims and objectives To screen the factors of intraoperatively acquired pressure ulcer and establish a new risk assessment model of intraoperatively acquired pressure ulcer. Design This is a prospective study. Methods A total of 1,963 patients who received neurosurgery, orthopaedics, paediatric surgery and cardiac surgery therapy in Sichuan Academy of Medical Science and Provincial People's Hospital in China from October 2015–October 2016 were enrolled in the study, and their clinical parameters were collected. Multivariable logistic regression analysis and decision tree analysis were used to analyse and screen the factors of intraoperatively acquired pressure ulcer and establish the risk assessment model of intraoperatively acquired pressure ulcer. Results The risk factors for intraoperatively acquired pressure ulcer included the application of external force during operation (β = 1.10, OR = 3.20), lean body mass (β = 1.08, OR = 2.95), time of operation ≥6 hr (β = 2.66, OR = 14.30), prone position operation (β = 1.13, OR = 3.10), cardiopulmonary bypass during operation (β = 1.72, OR = 5.59) and intraoperative blood loss (β = 0.67, OR = 1.95). The new risk assessment model showed that the AUC of ROC curve was 0.897 (p
