The aim of this study was to assess the prevalence, incidence, and the associated factors of pressure injuries (PIs) among immobile hospitalised patients in China. Being immobile during hospitalisation put these patients at a higher risk of PIs. There is little literature about pressure injury (PI) prevalence or PI incidence in immobile hospitalised patients in hospitals in China. This was a multicentre, cross-sectional, exploratory descriptive study. A total of 23 985 immobile patients were recruited from 25 general hospitals in six provinces of China from November 1, 2015 to March 18, 2016. Information was collected on demographic characteristics, physical assessment information, and treatment and nursing care measures. The PI period prevalence was 3.38%, and the PI cumulative incidence was 1.23%. Most PIs (84.03%) were Stage 1 or Stage 2. A total of 48.22% of PIs occurred in the sacrum or heel region. In the multivariate analysis, the following factors were associated with higher PI prevalence: age, gender, length of immobility, type of hospital, modified Braden Scale score, urinary incontinence, faecal incontinence, low serum albumin, the usage of fixation or restraint devices, and patient's discharge diagnosis (lower limb fracture, malnutrition, and spinal cord injury). PI prevalence for immobile hospitalised patients in the study was lower than those reported in literature. However, because of the large population in China, the number of patients who suffer with PIs can be very high. The relating factors of higher PI prevalence identified in this study were consistent with current literature. Patients with a higher number of these associated factors should be monitored more closely, and preventative measures should be taken to prevent PI occurrence in high-risk populations.
