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.

Objective:To explore the effect of Kangfuxin solution combined with triamcinolone and Econazole cream in elderly patients with hip fracture complicated with incontinence dermatitis, and to provide reference for clinical nursing.Methods:A randomized controlled trial was conducted to select 80 elderly patients with hip fracture complicated with incontinence dermatitis who were hospitalized in the Orthopedics Department of the First Medical Center of the PLA General Hospital from February 2023 to March 2024 by convenient sampling method. They were divided into the experimental group and the control group with 40 cases in each group according to random number table method. The experimental group was treated with Kangfuxin solution combined with triamcinolone and econazole cream for incontinence dermatitis. Intervention was stopped after 2 weeks of intervention or the incontinence dermatitis reached the clinical healing standard. In the control group, 3M spray was used to care the affected area of incontinence dermatitis, intervention was stopped after 2 weeks or the incontinence dermatitis reached the clinical healing standard. Incontinence dermatitis Skin Injury Assessment Scale (IADS) and perineal skin assessment tool PAT were used to evaluate the skin status of the two groups, and the healing time and treatment effectiveness of the two groups were compared.Results:In the control group, there were 11 males and 29 females, with age of (76.53 ± 8.67)years. There were 9 males and 31 females in the experimental group, with age of (76.56 ± 8.69)years, and there was no significant differences in baseline data between the two groups (all P>0.05). After intervention, the IADS and PAT scores of the control group were (27.13±5.22) points and (5.11 ± 0.94) points respectively, which were significantly higher than those of the experimental group (25.43 ± 4.15) points and (3.73 ± 1.21) points, and the differences were statistically significant ( t=7.22, 8.21, both P<0.05). The effective treatment in the experiment group was 97.5% (39/40), which was significant higher than 72.5% (29/40) in the control group ( χ2=13.25, P<0.05). The healing time of experimental group was (4.57 ± 3.44) d, which was significantly shorter than that of control group (9.23 ± 4.19) d, with statistical significance ( t=11.61, P<0.05). Conclusions:The combined application of Kangfuxin solution and triamcinolone and Econazole cream has a significant effect on improving incontinence dermatitis and perineal health in elderly patients with hip fracture, can effectively reduce symptoms and accelerate skin healing, and has certain clinical application value.

Objective:To explore the relationship between hemoglobin variability (Hb-var) and risk of all-cause death and cardiovascular death in patients with peritoneal dialysis (PD), and to provide basis for reducing the risk of death in PD patients.Methods:It was a multicenter retrospective cohort study. The clinical data of regular PD patients from Nanfang Hospital of Southern Medical University, Shunde Hospital of Southern Medical University, Foshan First People's Hospital and Ganzhou People's Hospital from July 1, 2008 to December 31, 2019 were collected. Hb-var was calculated based on hemoglobin at baseline before PD and in the first year after PD. The patients were divided into low Hb-var group, moderate Hb-var group and high Hb-var group according to the tertiles of first year Hb-var, and the differences of baseline clinical data among three groups were compared. Follow-up endpoints included death, transfer to hemodialysis, transfer to kidney transplantation, transfer to other centers, loss of follow-up, or on December 31, 2021. Cox regression analysis model was used to analyze the association of the first-year Hb-var with all-cause death and cardiovascular death. Fine-Gray competitive risk regression model was used to evaluate the impact of competitive events on mortality risk.Results:A total of 1 562 patients with PD were included in the study, aged (47.6±13.8) years old, with 821 males (52.6%) and baseline hemoglobin of 81 (69, 94) g/L. Hb-var in the first year of PD was 26.6 (16.7, 40.3) g/L. There were statistically significant differences in age, body mass index, serum albumin, hemoglobin, serum creatinine, serum calcium, serum phosphorus, intact parathyroid hormone and the proportion of renin-angiotensin system inhibitors among low Hb-var group (<20.0 g/L), moderate Hb-var group (20.0-35.5 g/L) and high Hb-var group (≥35.5 g/L, all P<0.05). The follow-up time was 33 (19, 51) months, and 208 patients (13.3%) died, among which 111 patients (53.4%) died of cardiovascular death. Multivariate Cox regression analysis showed that the higher Hb-var in the first year, the lower the risk of all-cause death ( HR=0.98, 95% CI 0.97-0.99, P=0.018) and cardiovascular death ( HR=0.98, 95% CI 0.97-0.99, P=0.041) in PD patients. Compared with low Hb-var group, the risk of all-cause death ( HR=0.56, 95% CI 0.37-0.82, P=0.003) and cardiovascular death ( HR=0.54, 95% CI 0.31-0.95, P=0.032) was lowest in the high Hb-var group. The competitive risk regression model analysis showed that Hb-var in the first year was still negatively correlated with the risk of all-cause death ( HR=0.98, 95% CI 0.97-0.99, P=0.041) and cardiovascular death ( HR=0.98, 95% CI 0.97-0.99, P=0.039). Conclusion:High Hb-var in the first year is associated with low risk of all-cause death and cardiovascular death in PD patients with severe anemia at baseline.
