Postoperative delirium, one of the common complications in patients with hip fracture, has a high incidence and poor prognosis. As there have been no effective treatments for this complication, early prediction and intervention is the most effective method available to reduce its occurrence. This study reviews the types and characteristics of the patients who suffer from postoperative delirium after hip fracture, as well as the risk factors that have been currently found. The risk prediction models for postoperative delirium are also analyzed and compared in hip fracture patients from the perspectives of cohorts included, research design, model construction and validation methods, model performance, and clinical application. The limitations of existing models are analyzed to foresee the development trend of future delirium prediction models for hip fracture patients. This study aims to help clinical healthcare professionals to identify as soon as possible those who will face a high risk for postoperative delirium after hip fracture surgery and to work out algorithms for targeted prevention and management.

Objective:To investigate status quo of smart elderly care needs of community older adults in main urban areas of Chongqing, and to analyze the influencing factors.Methods:A survey, using convenience sampling method, involving 452 community older adults in 9 districts in urban areas of Chongqing, was conducted by the General questionnaire and Smart Elderly Care Needs questionnaire from October to December, 2021. And analyze the influencing factors of the demand for smart elderly care needs.Results:In the demand for smart elderly care needs of the community elderly in the main urban area of Chongqing, the scores of needs for daily life care, social and emotional support, daily medical care and emergency medical assistance were 3.39 ± 1.45, 3.60 ± 1.28, 3.80 ± 1.19 and 3.87 ± 1.27, respectively. The results of ordinal Logistic analysis showed that gender, age, living alone and education level were the influencing factors of daily life care needs( P<0.05). Age and living alone were the influencing factors of social and emotional support and emergency medical assistance needs( P<0.05). Daily medical care needs were influenced by living alone( P<0.05). Conclusions:Community older adults in main urban areas of Chongqing have high level of needs for smart elderly care. Smart elderly care should focus on the ones with higher demand, namely those living alone, older, male and poorly educated, so as to promote active aging.
