| description | Objectives This study aimed to investigate the incidence of oral mucous membrane medical device-related pressure injury (MDR-MM PI) and identify its risk factors in critically ill patients undergoing orotracheal intubation, guided by the conceptual framework of pressure injury development. The findings aim to inform effective preventive strategies in intensive care settings.Design Prospective cohort study.Setting General intensive care unit (ICU) of a tertiary care hospital in China.Participants Patients aged ≥18 years who underwent oral endotracheal intubation were included between July 2023 and July 2024. Exclusion criteria were (1) existing oral mucosal injuries before intubation, (2) radiotherapy-induced oral mucositis, (3) patients undergoing oral surgery and (4) intubation duration of less than 24 hours. A total of 420 patients met the criteria and were included in the final analysis.Outcomes The outcomes included the incidence of oral MDR-MM PI, the time to oral MDR-MM PI occurrence and the identification of risk factors using multivariate Cox regression analysis.Results Among the 420 patients, 43.10% (n=181) developed oral MDR-MM PI, with Stage I accounting for 38.67% and Stage II for 61.33%. The lower lip (38.67%) and upper lip (38.12%) were the most common injury sites. The median time to oral MDR-MM PI occurrence was 8 days (95% CI: 7.134 to 8.866). Significant risk factors identified through multivariate Cox regression included sepsis (HR=2.090, 95% CI: 1.273 to 3.431), lower platelet (PLT) counts (HR=0.997, 95% CI: 0.995 to 0.999) and use of hard bite blocks (HR=1.553, 95% CI: 1.082 to 2.230). Probiotics showed a protective effect (HR=0.632, 95% CI: 0.468 to 0.854, p<0.05).Conclusions Critically ill patients undergoing orotracheal intubation in ICUs are at high risk of developing oral MDR-MM PI, with a median onset time of 8 days. Risk factors such as sepsis, low PLT counts and hard bite blocks were identified, while probiotics were found to have a protective effect. These findings highlight the need for targeted preventive strategies to reduce oral MDR-MM PI incidence in ICU settings. |
