RESUMO
BACKGROUND: There is well-established evidence to understand the characteristics of falls among the older patients with hip fracture in many countries, but very little knowledge existed in China. This study described the characteristics of falls in older patients with hip fractures from six Chinese hospitals. METHODS: This cross-sectional study is a post-hoc descriptive analysis of a recently completed trial. Eligible patients were aged 65 years and older, with confirmed hip fractures due to falls, and were admitted to the hospital within 21 days of the fracture. All patients were consecutively enrolled and screened within one year (November 15, 2018, to November 14, 2019). The collected data included patient demographics and fall-related information. RESULTS: A total of 1,892 patients' fall-related information were described. Most patients with hip fractures caused by falls were in the oldest old age group (60.4% in age group ≥ 80), with an overall average age of 80.7 (7.6) years. There were more females (n = 1,325, 70.0%) than males (n = 567, 30.0%). The majority lived in urban (n = 1,409, 74.5%). Most falls (n = 1,237, 67.3%) occurred during the daytime (6:01-18:00). There were 1,451 patients had their falls occurring at home (76.7%). Lost balance (n = 1,031, 54.5%) was reported as the primary reason to cause falls. The most common activity during a fall was walking (n = 1,079, 57.0%). CONCLUSIONS: Although the incidence of fall-related hip fractures in China is unclear, preventing falls and fall-related hip fractures in older people remains an urgent health concern as the ageing society increases. Studies with larger sample size and diverse population are needed to robustly understand this growing epidemic.

OBJECTIVE: To evaluate the clinical effectiveness of orthogeriatric co-management care in long-lived elderly hip fracture patients (age ≥ 90). METHODS: Secondary analysis was conducted in long-lived hip fracture patients between 2018 to 2019 in 6 hospitals in Beijing, China. Patients were divided into the orthogeriatric co-management group (CM group) and traditional consultation mode group (TC group) depending on the management mode. With 30-day mortality as the primary outcome, multivariate regression analyses were performed after adjusting for potential covariates. 30-day mobility and quality of life were compared between groups. RESULTS: A total of 233 patients were included, 223 of whom completed follow-up (125 in CM group, 98 in TC group). The average age was 92.4 ± 2.5 years old (range 90-102). The 30-day mortality in CM group was significantly lower than that in TC group after adjustments for (2.4% vs. 10.2%; OR = 0.231; 95% CI 0.059 ~ 0.896; P = 0.034). The proportion of patients undergoing surgery and surgery performed within 48 h also favored the CM group (97.6% vs. 85.7%, P = 0.002; 74.4% vs. 24.5%, P < 0.001; respectively). In addition, much more patients in CM group could walk with or without aids in postoperative 30 days than in the TC group (87.7% vs. 60.2%, P < 0.05), although differences were not found after 1-year follow-up. And there was no significant difference in total cost between the two groups (P > 0.05). CONCLUSIONS: For long-lived elderly hip fracture patients, orthogeriatric co-management care lowered early mortality, improved early mobility and compared with the traditional consultation mode.

The aim of this investigation was to assess expression of programmed death-1 (PD-1) and inflammatory status after hip fracture surgery in aged mice and to evaluate the effect of anti-PD-1 antibody intervention. Male C57BL/6 mice aged 22-28 months underwent hip fracture and femoral intramedullary pinning or a sham procedure. Expression of PD-1 was measured on CD4+ and CD8+ T cells. Additionally, the effects of anti-PD-1 antibody on lymphocyte apoptosis, cytokine production, bacterial clearance, and survival were determined. Expression of PD-1 on T cells was upregulated in mice after hip fracture and surgery compared to sham controls. Administration of anti-PD-1 antibody prevented T lymphocyte apoptosis, increased IFN-γ production in splenocytes, and decreased systemic inflammation. Antibody blockade of PD-1 significantly decreased susceptibility to bacteria and improved survival rates of aged mice after hip fracture and surgery followed by the induction of Pseudomonas aeruginosa pneumonia. This study showed that hip fracture and surgical trauma cause significant increases in PD-1 expression in aged mice. Antibody blockade of PD-1 partially reverses T cell apoptosis, decreases the systemic inflammatory response and susceptibility to bacteria, and reduces mortality.

Background: The clinical effectiveness of multidisciplinary co-managed care for hip fracture patients in China has been demonstrated in a multicenter non-randomized controlled study. This study aims to estimate the cost-effectiveness of the co-managed care. Methods: The study is based on a multicenter clinical trial (n = 2071) in China. We developed a state transition microsimulation model to estimate the cost-effectiveness of the co-managed care compared with usual care for hip fracture patients from healthcare system perspective. The costs incorporated into the model included hospitalization costs, post-discharge expenses, and secondary fracture therapy costs. Effectiveness was measured using quality-adjusted life years (QALYs). Costs and effects were discounted at 5% annually. A simulation cycle length of 1-year and a lifetime horizon were employed. The cost-effectiveness threshold was established at USD 37,118. To address uncertainties, one-way deterministic sensitivity analysis and probabilistic sensitivity analysis were conducted. Findings: In the base case analysis, the co-managed care group had a lifetime cost of USD 31,571 and achieved an effectiveness of 3.22 QALYs, whereas the usual care group incurred a cost of USD 27,878 and gained 2.85 QALYs. The incremental cost-effectiveness ratio was USD 9981 per QALY gained; thus the co-managed care model was cost-effective. The cost-effectiveness was sensitive to the age of having hip fractures and hospitalization costs in the intervention group. Interpretation: The co-managed care in hip fracture patients represents value for money, and should be scaled up and prioritized for funding in China. Funding: The study is supported by Capital's Funds for Health Improvement and Research (2022-1-2071, 2018-1-2071).
RESUMO
BACKGROUND: Clinical guidelines recommend orthogeriatric care to improve older hip fracture patients' outcomes, but few studies have been conducted in China. This study evaluated the effects of an orthogeriatric co-management care model in six Chinese hospitals. METHODS: This non-randomised controlled study was designed as an exploratory trial and was conducted in 3 urban and 3 suburban hospitals. Eligible patients were aged ≥ 65 years with X-ray confirmed hip fracture and admitted to hospital within 21 days of injury. All patients received three times follow-ups within one year (1-month, 4-month and 12-month post admission). Co-management care was implemented in 1 urban hospital, while usual care continued in 5 urban and suburban hospitals. Patient demographics, pre-, peri- and post-operative information, complications and mortality were collected at baseline and follow-ups. The primary outcome was proportion of patients receiving surgery within 48 hours from ward arrival. Secondary outcomes included osteoporosis assessment, in-hospital rehabilitation, length of hospital stay, in-hospital mortality and one-year cumulative mortality. FINDINGS: There were 2,071 eligible patients enrolled (1,110 intervention, 961 control). Compared to usual care, a significantly higher proportion of intervention patients received surgery within 48 hours (75% vs 27%, p<0.0001), osteoporosis assessment (99.9% vs 60.6%, p<0.0001), rehabilitation (99.1% vs 3.9%, p<0.0001) and shorter length of hospital stay (6.1 days vs 12.0 days, p<0.0001). The intervention group saw a significant lower in-hospital mortality rate than the control group (adjusted relative risk 0.021, 95% CI 0.001 to 0.45, P=0.01). One-year cumulative mortality was also significantly reduced in the intervention group (hazard ratio 0.59, 95% CI 0.38 to 0.80, p=0.01). INTERPRETATION: Co-management care of older hip fracture patients resulted in better outcomes, including decreased time to surgery, improved clinical management, and reduced one-year mortality. A randomised controlled trial is needed to provide definitive evidence. FUNDING: The study is supported by Capital's Funds for Health Improvement and Research (2018-1-2071).
RESUMO
Background: The enhanced recovery after surgery (ERAS) program is aimed to shorten patients' recovery process and improve clinical outcomes. This study aimed to compare the outcomes between the ERAS program and the traditional pathway among patients with ankle fracture and distal radius fracture. Methods: This is a multicenter prospective clinical controlled study consisting of 323 consecutive adults with ankle fracture from 12 centers and 323 consecutive adults with distal radial fracture from 13 centers scheduled for open reduction and internal fixation between January 2017 and December 2018. According to the perioperative protocol, patients were divided into two groups: the ERAS group and the traditional group. The primary outcome was the patients' satisfaction of the whole treatment on discharge and at 6 months postoperatively. The secondary outcomes include delapsed time between admission and surgery, length of hospital stay, postoperative complications, functional score, and the MOS item short form health survey-36. Results: Data describing 772 patients with ankle fracture and 658 patients with distal radius fracture were collected, of which 323 patients with ankle fracture and 323 patients with distal radial fracture were included for analysis. The patients in the ERAS group showed higher satisfaction levels on discharge and at 6 months postoperatively than in the traditional group (P < 0.001). In the subgroup analysis, patients with distal radial fracture in the ERAS group were more satisfied with the treatment (P=0.001). Furthermore, patients with ankle fracture had less time in bed (P < 0.001) and shorter hospital stay (P < 0.001) and patients with distal radial fracture received surgery quickly after being admitted into the ward in the ERAS group than in the traditional group (P=0.001). Conclusions: Perioperative protocol based on the ERAS program was associated with high satisfaction levels, less time in bed, and short hospital stay without increased complication rate and decreased functional outcomes.
