Objective To make a systematic review of pressure ulcers risk factors in critically ill patients. Methods We systematically reviewed all articles related to the pressure ulcers risk factors in critically ill patients. The Cochrane Library, PubMed, EMBASE, Web of Science Core Collection, CNKI, WANFANG and SinoMed were searched to August 2016. Results In total, 13 eligible articles were included. These studies included 18, 184 critically ill patients, six studies were classified as high quality, and seven were classified as moderate quality. Risk factors for the development of pressure ulcers include age, ICU stay, diabetes, mean arterial pressure<60-70 mmHg (1 mmHg=0.133 kPa), mechanical ventilation and mechanical ventilation, drugs, sedation and postural changes. Conclusions There is no single factor that can explain the occurrence of pressure ulcers. So it is in a variety of factors interaction, the occurrence of a significant increase in risk.
