Analysis of Occurrence Characteristics and Influencing Factors of Out-of-Hospital Induced Stress Injury in Patients with Community-Acquired Pneumonia in Respiratory Intensive Care Unit.

Background: We aimed to evaluate the characteristics of a stress injury in community-acquired pneumonia (CAP) patients in the respiratory intensive care unit (RICU) and analyze the risk factors, to provide evidence for clinical prevention and treatment. Methods: This retrospective study was conducted in RICU at Qilu Hospital of Shandong University, China. We selected 85 patients with traumatic CAP who were brought in from January 2019 to December 2020 as the case group and 167 patients without traumatic CAP hospitalized in the same period as the control group. Multivariate binary Logistic regression analysis was used to explore the influencing factors. Results: The incidence rate of a stress injury in 252 patients was 33.73%. The most affected region found in these patients was the sacrococcygeal region (24.26%). Most of the patients were presented in stage one (49.50%). Factors associated with a stress-induced injury in RICU, CAP patients were CURB-65 combined with cerebrovascular disease, fever combined with heart disease and albumin was found as an independent risk factor. Conclusion: Attempts to improve stress injury in CAP patients through setting measurable process of care standards are to be encouraged. An approach including the patient's clothes and bedding should be changed frequently, nutrition should be managed and the skin of the patient should be kept clean and dry. The occurrence of stress can further be reduced by the use of protective tools and the timely participation of the family members in patient management.
