[Retrospective analysis of 2 997 inpatients with skin and soft tissue injuries].
Objective: To analyze the epidemiological characteristics and the related information on the diagnosis and treatment of inpatients with skin and soft tissue injuries. Methods: The medical records of inpatients with skin and soft tissue injuries who were admitted to the Fourth Medical Center of PLA General Hospital (hereinafter referred to as the author's unit) from January 1, 2014 to December 31, 2018, conforming to the study criteria, were retrospectively analyzed. The indexes included inpatients'gender, age, wound course, underlying disease, wound type, wound site, and wound microbiological culture result, methods and outcome of treatment, type of medical payment, hospital day, and hospitalization cost. ⋯ Patients with chronic wounds are often complicated with various underlying diseases, and the course of disease is long, so the constituent ratio of cured patients is lower than that of patients with acute wounds. Patients with skin and soft tissue injuries have long hospital days and high proportion of material cost, which are directly related to the clinical characteristics and long treatment cycle of chronic wounds. Therefore, it is suggested that the medical insurance administration department should adjust the consumption ratio and other management indicators according to the actual clinical needs of elderly patients with chronic wounds.

[Establishment of nomogram predicting model for the death risk of extremely severe burn patients and the predictive value].
Objective: To explore the death risk factors of extremely severe burn patients, establish a death risk nomogram predicting model, and investigate the predictive value for death risk of extremely severe burn patients. Methods: The medical records of 231 extremely severe burn patients (190 males and 41 females, aged 18-60 years) who were admitted to the Institute of Burn Research of the First Affiliated Hospital of Army Medical University from January 2010 to October 2018 and met the inclusion criteria were analyzed retrospectively. According to the final outcome, the patients were divided into survival group of 173 patients and death group of 58 patients. ⋯ The optimum threshold of ROC curve was 0.23, the sensitivity and specificity of optimum threshold were 86.0% and 80.0%, respectively, and the area under ROC curve was 0.90 (95% confidence interval=0.86-0.94, P<0.01). Conclusions: Severe burns and damage and/or failure of organ are the main death causes of extremely severe burn patients. The death risk nomogram predicting model established on the basis of use of ventilator, use of CRRT, and burn index have good predictive ability for death of extremely severe burn patients.
