Survival and functional outcomes after hip fracture among nursing home residents

Liposomal Bupivacaine Does Not Decrease Postoperative Pain in Patients with Intracapsular Femoral Neck Fracture Treated with Hemiarthroplasty: HEAT-A Randomized, Controlled Trial

BACKGROUND

Liposomal bupivacaine (LB) is a long-lasting local anesthetic agent that was developed for use in the surgical setting to help manage postoperative pain. The objective of this study was to evaluate the effect of LB on postoperative pain, function, and overall hospital course in patients with intracapsular hip fractures who were treated with hip hemiarthroplasty.

METHODS

This was a single-center, randomized prospective double-blinded study of 50 patients with an isolated intracapsular femoral neck fracture who were treated with hip hemiarthroplasty from 2018 to 2022. The study group consisted of 25 patients who were treated with intraoperative LB and bupivacaine hydrochloride injections, while the control group consisted of 25 patients who were treated with intraoperative bupivacaine hydrochloride injections only. Primary outcomes were a visual analog scale (VAS) score for pain, total morphine milligram equivalents (MME), delirium, and time to ambulation with physical therapy.

RESULTS

No significant differences between the study and control groups were found in any of the outcomes measured. Most notably, there were no differences in the average postoperative pain score (VAS, 2.26 versus 2.7; p = 0.34), total MME used postoperatively (11.73 versus 9.98 MME; p = 0.71), and postoperative day of discharge (4.00 versus 3.88 days; p = 0.82).

CONCLUSIONS

The results of our study suggest that use of LB is not associated with substantially improved postoperative pain or function or with a shorter hospital course following hip hemiarthroplasty for a femoral neck fracture. Given the higher cost of LB compared with standard postoperative pain modalities, it is worth questioning its use in the setting of geriatric hip fractures.

A retrospective chart analysis with 5-year follow-up of early care for geriatric hip fracture patients: why we should continue talking about hip fractures

BACKGROUND

Timing of surgery remains a topic of debate for hip fracture treatment in the geriatric patient population. The quality indicator "early surgery" was implemented in 2014 at the Department of Trauma Surgery of the University Hospitals Leuven to enhance timely operative treatment. In this follow-up study, we aim to evaluate the performance of this quality indicator, the clinical outcomes, and room for improvement.

METHODS

The charts of 1190 patients surgically treated for an acute hip fracture were reviewed between June 2017 and May 2022 at the University Hospitals Leuven. Primary endpoints were adherence to early surgery, defined as surgery within the next calendar day, and the evaluation of the reasons for deviating from this protocol. Secondary endpoints were length of stay (LOS); intensive care unit (ICU) admission and length of ICU stay; mortality after 30 days, 60 days, 90 days, and 6 months; and 90-day readmission rate. Pearson's Chi-square test and Mann-Whitney U test were used for data analysis.

RESULTS

One thousand eighty-four (91.1%) patients received early surgery versus 106 (8.9%) patients who received delayed surgery. The main reasons for surgical delay were the use of anticoagulants (33%), a general health condition not allowing safe surgery and/or existing comorbidities requiring workup prior to surgery (26.4%), and logistical reasons (17.9%). Patient delay and transfer from other hospitals were responsible for respectively 8.5% and 6.6% of delayed surgery. Early surgery resulted in a significantly shorter LOS and ICU stay (12 [8-25] vs. 18 [10-36] and 3 [2-6] vs. 7 [3-13] days, early vs. delayed surgery, respectively). No significant reduction was observed in ICU admission, mortality, and readmission rate.

CONCLUSION

We have been able to maintain the early surgery hip fracture protocol in approximately 90% of the patients. Comorbidities and anticoagulant use were responsible for delayed surgery in the majority of the patients. Correct implementation of the existing protocol on anticoagulant use could lead to a one-third decrease in the number of delayed surgeries. Subsequently, since the LOS and ICU stay in the delayed surgery group were significantly longer, a further increase of early surgery will lower the current economic burden.

Strategies to improve end-of-life decision-making and palliative care following hip fracture in frail older adults: a scoping review

BACKGROUND

Although surgery is the gold standard following a hip fracture, the potential for rehabilitation and survival rates are low in frail older patients. Some patients may derive more benefit from palliative care. The objectives of this review were to identify the available strategies to improve end-of-life decision-making and palliative care for frail patients with hip fractures and to synthetise their level of support.

METHODS

We conducted a scoping review of the scientific and grey literature, searching seven databases and websites of associations. We included all study designs, expert opinion articles and clinical practice guidelines (CPGs). Data were synthetised according to the Approach to Patient with Limited Life Expectancy and Hip Fracture framework. The number of research items and their level of evidence were tabulated for each of the recommended strategies.

RESULTS

Of the 10 591 items identified, 34 were eligible. The majority of included articles were original research studies (n = 15). Half of the articles and CPGs focused on intervention categories (55%) such as goals of care discussion and comfort care, followed by factors to consider in the end-of-life decision-making process (25%) and prognosis assessments (20%), mainly through the estimation of life expectancy. The level of evidence for these strategies remains low, given the limited number of prospective studies supporting them.

CONCLUSIONS

This scoping review highlighted that end-of-life care in frail older patients with a hip fracture remains understudied. The strategies identified could be prioritised for future research to improve the well-being of the target population while promoting sustainable resource management.

The Quality of Dying in Frail Institutionalized Older Patients After Nonoperative and Operative Management of a Proximal Femoral Fracture: An In-Depth Analysis

Proximal femoral fractures in frail patients have a poor prognosis. Despite the high mortality, little is known about the quality of dying (QoD) while this is an integral part of palliative care and could influence decision making on nonoperative- (NOM) or operative management (OM). To identify the QoD in frail patients with a proximal femoral fracture. Data from the prospective FRAIL-HIP study, that studied the outcomes of NOM and OM in institutionalized older patients ≥70 years with a limited life expectancy who sustained a proximal femoral fracture, was analyzed. This study included patients who died within the 6-month study period and whose proxies evaluated the QoD. The QoD was evaluated with the Quality of Dying and Death (QODD) questionnaire resulting in an overall score and 4 subcategory scores (Symptom control, Preparation, Connectedness, and Transcendence). In total 52 (64% of NOM) and 21 (53% of OM) of the proxies responded to the QODD. The overall QODD score was 6.8 (P25-P75 5.7-7.7) (intermediate), with 34 (47%) of the proxies rating the QODD 'good to almost perfect'. Significant differences in the QODD scores between groups were not noted (NOM; 7.0 (P25-P75 5.7-7.8) vs OM; 6.6 (P25-P75 6.1-7.2), P = .73). Symptom control was the lowest rated subcategory in both groups. The QoD in frail older nursing home patients with a proximal femoral fracture is good and humane. QODD scores after NOM are at least as good as OM. Improving symptom control would further increase the QoD.

Hip Fracture Treatment and Outcomes Among Community-Dwelling People Living With Dementia

Importance

The decision for surgical vs nonsurgical treatment for hip fracture can be complicated among community-dwelling people living with dementia.

Objective

To compare outcomes of community-dwelling people living with dementia treated surgically and nonsurgically for hip fracture.

Design, Setting, and Participants

This retrospective cross-sectional study undertook a population-based analysis of national Medicare fee-for-service data. Participants included community-dwelling Medicare beneficiaries with dementia and an inpatient claim for hip fracture from January 1, 2017, to June 30, 2018. Analyses were conducted from November 10, 2022, to October 17, 2023.

Exposure

Surgical vs nonsurgical treatment for hip fracture.

Main Outcomes and Measures

The primary outcome was mortality within 30, 90, and 180 days. Secondary outcomes consisted of selected post-acute care services.

Results

Of 56 209 patients identified with hip fracture (73.0% women; mean [SD] age, 86.4 [7.0] years), 33 142 (59.0%) were treated surgically and 23 067 (41.0%) were treated nonsurgically. Among patients treated surgically, 73.3% had a fracture of the femoral head and neck and 40.2% had moderate to severe dementia (MSD). Among patients with MSD and femoral head and neck fracture, 180-day mortality was 31.8% (surgical treatment) vs 45.7% (nonsurgical treatment). For patients with MSD treated surgically vs nonsurgically, the unadjusted odds ratio (OR) of 180-day mortality was 0.56 (95% CI, 0.49-0.62; P < .001) and the adjusted OR was 0.59 (95% CI, 0.53-0.66; P < .001). Among patients with mild dementia and femoral head and neck fracture, 180-day mortality was 26.5% (surgical treatment) vs 34.9% (nonsurgical treatment). For patients with mild dementia who were treated surgically vs nonsurgically for femoral head and neck fracture, the unadjusted OR of 180-day mortality was 0.67 (95% CI, 0.60-0.76; P < .001) and the adjusted OR was 0.71 (95% CI, 0.63-0.79; P < .001). For patients with femoral head and neck fracture, there was no difference in admission to a nursing home within 180 days when treated surgically vs nonsurgically.

Conclusions and Relevance

In this cohort study of community-dwelling patients with dementia and fracture of the femoral head and neck, patients with MSD and mild dementia treated surgically experienced lower odds of death compared with patients treated nonsurgically. Although avoiding nursing home admission is important to persons living with dementia, being treated surgically for hip fracture did not necessarily confer a benefit in that regard. These data can help inform discussions around values and goals with patients and caregivers when determining the optimal treatment approach.

Navigating Post-Traumatic Osteoporosis: A Comprehensive Review of Epidemiology, Pathophysiology, Diagnosis, Treatment, and Future Directions

Post-traumatic osteoporosis (PTO) presents a significant challenge in clinical practice, characterized by demineralization and decreased skeletal integrity following severe traumatic injuries. This literature review manuscript addresses the knowledge gaps surrounding PTO, encompassing its epidemiology, pathophysiology, risk factors, diagnosis, treatment, prognosis, and future directions. This review emphasizes the complexity of the etiology of PTO, highlighting the dysregulation of biomineralization processes, inflammatory cytokine involvement, hormonal imbalances, glucocorticoid effects, vitamin D deficiency, and disuse osteoporosis. Moreover, it underscores the importance of multidisciplinary approaches for risk mitigation and advocates for improved diagnostic strategies to differentiate PTO from other musculoskeletal pathologies. This manuscript discusses various treatment modalities, including pharmacotherapy, dietary management, and physical rehabilitation, while also acknowledging the limited evidence on their long-term effectiveness and outcomes in PTO patients. Future directions in research are outlined, emphasizing the need for a deeper understanding of the molecular mechanisms underlying PTO and the evaluation of treatment strategies' efficacy. Overall, this review provides a comprehensive overview of PTO and highlights avenues for future investigation to enhance clinical management and patient outcomes.

Benefits of surgical treatment within 48 h of proximal femoral fracture in centenarians: a retrospective cohort study

Introduction

Proximal femoral fractures in aging populations represent a significant concern, with an increasing prevalence among individuals aged ≥100 years. The existing research does not provide robust guidance for clinicians managing older patients aged ≥100 years with proximal femoral fractures. We investigated the safety and efficacy of surgical treatment in patients aged ≥100 years with proximal femoral fractures and evaluated the impact of early surgery on their outcomes.

Methods

This retrospective cohort study involved 15 patients aged ≥100 years who underwent surgical treatment of proximal femoral fractures; the control group included 137 patients in their 90s. Data were collected between January 2010 and December 2017. Evaluation items included patient characteristics, surgical details, perioperative complication rates, length of hospital stay, the proportion of patients discharged to the same facility or home, rate of regaining walking ability, and 1-year survival rate.

Results

The patients aged ≥100 years and those in their 90s had comparable outcomes. Thus, age alone does not dictate surgical success. Early surgery (≤48 h) was associated with trends toward improved perioperative complications, ambulatory ability, and return to original living environment.

Discussion

This study underscores the potential benefits of surgical intervention for proximal femoral fractures in patients aged ≥100 years, indicating the relevance of early surgery (≤48 h). Our findings emphasized the importance of timely intervention and evidence-based decision-making for this demographic. Clinicians, policymakers, and patients could benefit from our insights to enhance fracture management strategies, along with future research endeavors to validate and expand our results in larger multicenter cohorts.

Current surgical status of hip fracture among elderly in China

OBJECTIVE

Hip fracture patients are recommended to undergo surgery within 24-36 h. The present study aimed to analyze the current status of hip fracture surgery among the elderly in China.

METHODS

The baseline information, such as the patient's age, gender, place of residence, place of treatment, fracture type, admission, and operation time, of hip fracture patients >65-years-old were retrieved from the hospital quality monitoring system (HQMS) database from 2013 to 2017 and analyzed.

RESULTS

A total of 304,279 patients >65-years-old with hip fractures were included in this study. The average length of hospital stay was 15 days, and the average waiting time for surgery after admission was 96 h. The average surgery rate of elderly hip fractures in China was 59.6 %, of which the lowest was recorded in the Northwest China (46.4 %).

CONCLUSIONS

The major issues in diagnosing and treating elderly patients with hip fractures in China are the long waiting time for surgery and the low surgery rate.

The process of social death in patients with hip fracture

People with chronic disability and uncontrollable long-term complications following hip fracture have characterist.ics that may predispose them to social death. Continuous physical disability can have negative physical, psychological, and social consequences in these patients. To design care interventions for preventing and controlling social death, it is essential to identify the dimensions and characteristics of this process. Therefore, the present study aimed to explain the process of social death in hip fracture patients. In this study, which was conducted using a grounded theory approach, 20 patients were selected with maximum diversity and 9 professional and non-professional caregivers also through purposive sampling followed by theoretical sampling. Data were collected through semi-structured in-depth interviews, field notes, and observations. Data were analyzed using the approach proposed by Corbin and Strauss in stages including data analysis for concepts and their dimensions and characteristics, the context, process extraction, and integration of the categories. One core category and 16 main categories, which consisted of 55 subcategories and 212 primary concepts, were extracted. The results showed that the core process of social death in hip fracture is an intentional self-destruction for getting liberated from the conditions of the illness and the disrupted social life after the fracture, which ultimately leads to outcomes such as isolation-seeking and death ideations in these patients. The core category of liberating self-destruction reflects the close relationship between the context, process, and outcomes of social death. The process of social death is social, multidimensional, and complex. So far, no explanatory theory has been presented for this group of patients. Therefore, the results of this study can play an important role in designing helpful interventions for preventing, modifying, and changing the phenomenon of social death.

Variation in care for patients presenting with hip fracture in six high-income countries: A cross-sectional cohort study

BACKGROUND

Hip fractures are costly and common in older adults, but there is limited understanding of how treatment patterns and outcomes might differ between countries.

METHODS

We performed a retrospective serial cross-sectional cohort study of adults aged ≥66 years hospitalized with hip fracture between 2011 and 2018 in the US, Canada, England, the Netherlands, Taiwan, and Israel using population-representative administrative data. We examined mortality, hip fracture treatment approaches (total hip arthroplasty [THA], hemiarthroplasty [HA], internal fixation [IF], and nonoperative), and health system performance measures, including hospital length of stay (LOS), 30-day readmission rates, and time-to-surgery.

RESULTS

The total number of hip fracture admissions between 2011 and 2018 ranged from 23,941 in Israel to 1,219,696 in the US. In 2018, 30-day mortality varied from 3% (16% at 1 year) in Taiwan to 10% (27%) in the Netherlands. With regards to processes of care, the proportion of hip fractures treated with HA (range 23%-45%) and THA (0.2%-10%) differed widely across countries. For example, in 2018, THA was used to treat approximately 9% of patients in England and Israel but less than 1% in Taiwan. Overall, IF was the most common surgery performed in all countries (40%-60% of patients). IF was used in approximately 60% of patients in the US and Israel, but only 40% in England. In 2018, rates of nonoperative management ranged from 5% of patients in Taiwan to nearly 10% in England. Mean hospital LOS in 2018 ranged from 6.4 days (US) to 18.7 days (England). The 30-day readmission rate in 2018 ranged from 8% (in Canada and the Netherlands) to nearly 18% in England. The mean days to surgery in 2018 ranged from 0.5 days (Israel) to 1.6 days (Canada).

CONCLUSIONS

We observed substantial between-country variation in mortality, surgical approaches, and health system performance measures. These findings underscore the need for further research to inform evidence-based surgical approaches.

Associations of Days Spent at Home Before Hip Fracture With Postfracture Days at Home and 1-Year Mortality Among Medicare Beneficiaries Living With Alzheimer's Disease or Related Dementias

BACKGROUND

Hip fracture is a disabling event experienced disproportionately by older adults with Alzheimer's disease or related dementias (ADRD). Claims information recorded prior to a hip fracture could provide valuable insights into recovery potential for these patients. Thus, our objective was to identify distinct trajectories of claims-based days at home (DAH) before a hip fracture among older adults with ADRD and evaluate associations with postfracture DAH and 1-year mortality.

METHODS

We conducted a cohort study of 16 576 Medicare beneficiaries living with ADRD who experienced hip fracture between 2010 and 2017. Growth mixture modeling was used to estimate trajectories of DAH assessed from 180 days prior to fracture until index fracture admission, and their joint associations with postfracture DAH trajectories and 1-year mortality.

RESULTS

Before a hip fracture, a model with 3 distinct latent DAH trajectories was the best fit. Trajectories were characterized based on their temporal patterns as Consistently High (n = 14 980, 90.3%), Low but Increasing (n = 809, 5.3%), or Low and Decreasing (n = 787, 4.7%). Membership in the Low and Decreasing prefracture DAH trajectory was associated with less favorable postfracture DAH trajectories, and a 65% higher 1-year mortality rate (hazard ratio 1.65, 95% confidence interval 1.45-1.87) as compared to those in the Consistently High trajectory. Similar albeit weaker associations with these outcomes were observed for hip fracture survivors in the Low but Improving prefracture DAH trajectory.

CONCLUSIONS

Distinct prefracture DAH trajectories among hip fracture survivors with ADRD are strongly linked to postfracture DAH and 1-year mortality, which could guide development of tailored interventions.

Clinician perspectives on nonoperative management of hip fractures during COVID-19

Aims

To identify factors influencing clinicians' decisions to undertake a nonoperative hip fracture management approach among older people, and to determine whether there is global heterogeneity regarding these factors between clinicians from high-income countries (HIC) and low- and middle-income countries (LMIC).

Methods

A SurveyMonkey questionnaire was electronically distributed to clinicians around the world through the Fragility Fracture Network (FFN)'s Perioperative Special Interest Group and clinicians' personal networks between 24 May and 25 July 2021. Analyses were performed using Excel and STATA v16.0. Between-group differences were determined using independent-samples t-tests and chi-squared tests.

Results

A total of 406 respondents from 51 countries answered the questionnaire, of whom 225 came from HIC and 180 from LMIC. Clinicians from HIC reported a greater median and mean estimated proportion of admitted patients with hip fracture undergoing surgery (median 96% (interquartile range (IQR) 95% to 99%); mean 94% (SD 8%)) than those from LMIC (median 85% (IQR 75% to 95%); mean 81% (SD 16%); p < 0.001). Global heterogeneity seems to exist regarding factors such as anticipated life expectancy, insufficient resources, ability to pay, treatment costs, and perception of risk in hip fracture management decision-making.

Conclusion

This study represents the first international sampling of clinician perspectives regarding nonoperative hip fracture management. Several factors seemed to influence the clinician decision-making process. Further research is needed to inform the development of best practice guidelines to improve decision-making and the quality of hip fracture care among older people.

Economic and Humanistic Burden Among Medicare-Aged Women With Fragility Fracture in the United States

OBJECTIVE

Describe patient characteristics, health care resource utilization, costs, and humanistic burden of women with Medicare insurance with incident fragility fracture who were admitted to post-acute-care (PAC).

DESIGN

Retrospective cohort study using 100% Medicare Fee-for-Service (FFS) data.

SETTING AND PARTICIPANTS

Community-dwelling female Medicare beneficiaries with incident fragility fracture January 1, 2017, to October 17, 2019, resulting in PAC admission to a skilled nursing facility (SNF), home-health care, inpatient-rehabilitation facility, or long-term acute-care hospital.

METHODS

Patient demographic/clinical characteristics were measured during 1-year baseline. Resource utilization and costs were measured during baseline, PAC event, and PAC follow-up. Humanistic burden was measured among SNF patients with linked Minimum Data Set assessments. Multivariable regression examined predictors of PAC costs after discharge and changes in functional status during SNF stay.

RESULTS

A total of 388,732 patients were included. Compared with baseline, hospitalization rates were 3.5, 2.4, 2.6, and 3.1 times higher and total costs 2.7, 2.0, 2.5, and 3.6 times higher for SNF, home-health, inpatient-rehabilitation, and long-term acute-care, respectively, following PAC discharge. Utilization of dual-energy X-ray absorptiometry (DXA) and osteoporosis medications remained low: 8.5% to 13.7% received DXA during baseline vs 5.2% to 15.6% following PAC; 10.2% to 12.0% received osteoporosis medication during baseline vs 11.4% to 22.3% following PAC. Dual eligibility for Medicaid (ie, low income) was associated with 12% higher costs; Black patients had 14% higher costs. Activities of daily living scores improved 3.5 points during SNF stay, but Black patients had 1.22-point lower improvement than White patients. Pain intensity scores showed small improvement (-0.8 points).

CONCLUSIONS AND IMPLICATIONS

Women admitted to PAC with incident fracture had high humanistic burden with little improvement in pain and functional status and significantly higher economic burden after discharge compared with baseline. Disparities in outcomes related to social risk factors were observed, with consistently low utilization of DXA and osteoporosis medications even after fracture. Results indicate a need for improved early diagnosis and aggressive disease management to prevent and treat fragility fractures.

Days alive and at home after hip fracture: a cross-sectional validation of a patient-centred outcome measure using routinely collected data

BACKGROUND

Days alive and at home (DAH) is a patient centered outcome measureable in routinely collected health data. The validity and minimally important difference (MID) in hip fracture have not been evaluated.

OBJECTIVE

We assessed construct and predictive validity and estimated a MID for the patient-centred outcome of DAH after hip fracture admission.

METHODS

This is a cross-sectional observational study using linked health administrative data in Ontario, Canada. DAH was calculated as the number of days alive within 90 days of admission minus the number of days hospitalised or institutionalised. All hospital admissions (2012-2018) for hip fracture in adults aged >50 years were included. Construct validity analyses used Bayesian quantile regression to estimate the associations of postulated patient, admission and process-related variables with DAH. The predictive validity assessed was the correlation of DAH in 90 days with the value from 91 to 365 days; and the association and discrimination of DAH in 90 days predicting subsequent mortality. MID was estimated by averaging distribution-based and clinical anchor-based estimates.

RESULTS

We identified 63 778 patients with hip fracture. The median number of DAH was 43 (range 0-87). In the 90 days after admission, 8050 (12.6%) people died; a further 6366 (10.0%) died from days 91 to 365. Associations between patient-level and admission-level factors with the median DAH (lower with greater age, frailty and comorbidity, lower if admitted to intensive care or having had a complication) supported construct validity. DAH in 90 days after admission was strongly correlated with DAH in 365 days after admission (r=0.922). An 11-day MID was estimated.

CONCLUSION

DAH has face, construct and predictive validity as a patient-centred outcome in patients with hip fracture, with an estimated MID of 11 days. Future research is required to include direct patient perspectives in confirming MID.

Association of preoperative nutritional status evaluated by the controlling nutritional status score with walking independence at 180 days postoperatively: a prospective cohort study in Chinese older patients with hip fracture

BACKGROUND

Malnutrition is significantly associated with unfavorable outcomes, but there is little high-level evidence to elucidate the association of malnutrition with losing walking independence (LWI) after hip fracture surgery. This study aimed to assess the association between preoperative nutritional status evaluated by the Controlling Nutritional Status (CONUT) score and walking independence at 180 days postoperatively in Chinese older hip fracture patients.

METHODS

This prospective cohort study included 1958 eligible cases from the SSIOS database. The restricted cubic spline was used to assess the dose-effect relationship between the CONUT score and the recovery of walking independence. Propensity score matching was performed to balance potential preoperative confounders, and multivariate logistic regression analysis was applied to assess the association between malnutrition and LWI with perioperative factors for further adjustment. Furthermore, inverse probability treatment weighting and sensitivity analyses were performed to test the robustness of the results and the Fine and Gray hazard model was applied to adjust the competing risk of death. Subgroup analyses were used to determine potential population heterogeneity.

RESULTS

The authors found a negative relationship between the preoperative CONUT score and recovery of walking independence at 180 days postoperatively, and that moderate-to-severe malnutrition evaluated by the CONUT score was independently associated with a 1.42-fold (95% CI, 1.12-1.80; P =0.004) increased risk of LWI. The results were overall robust. And in the Fine and Gray hazard model, the result was still statistically significant despite the apparent decrease in the risk estimate from 1.42 to 1.21. Furthermore, significant heterogeneities were observed in the subgroups of age, BMI, American Society of Anesthesiologists score, Charlson's comorbidity index, and surgical delay ( P for interaction < 0.05).

CONCLUSION

Preoperative malnutrition is a significant risk factor for LWI after hip fracture surgery, and nutrition screening on admission would generate potential health benefits.

Oral Health Status Using the Revised Oral Assessment Guide and Mortality in Older Orthopaedic Patients: A Cross-Sectional Study

Purpose

Orthogeriatric hospitalised patients with fractures of the lower limb constitute a vulnerable population with increased risk of morbidity, polypharmacy, and mortality as well as impaired oral health. The aim of this cross-sectional study was to investigate whether any relationship existed between oral health issues in older orthopaedic patients and mortality.

Material and Methods

The study population consisted of older orthopedic patients emergently admitted to a hospital in southern Sweden due to mainly fractures of the hip. Their oral health at admission was assessed by trained nurses using the revised oral assessment guide (ROAG), as well as examined by dental hygienists. Medical and demographic data were collected from medical records and mortality from the national population registry. Comorbidity was assessed using the Charlson Comorbidity Index (CCI). Data were analysed using foremost dichotomized data derived from mean values and then processed using multiple logistic regression adjusted for identified probable confounders.

Results

Of the 187 study patients (≥65 years) with a mean age of 81 (SD 7.9) years, 71% were women, mean CCI score was 6.7 and 90-days mortality 12.3%. Oral health issues (ROAG >8, 73%) consisted mainly of problems with teeth/dentures (41%), tongue (36%), lips (35%), and saliva (28%). In patients with any oral health impairment (ROAG >8) the 90-days mortality was significantly increased (p=0.040), using logistic regression analysis adjusted for age, gender, comorbidity, and use of ≥5 drugs. In patients with a ROAG score ≥10 (≥mean) the association remained at 90-days (p=0.029) and 180-days (p=0.013). Decayed teeth were present in 24% and was significantly associated with ROAG >8 (p=0.020).

Conclusion

The main finding of this study was a possible relationship between oral health impairment at admission and early mortality in orthogeriatric hospitalised patients. The opportunity to identify their oral health problems can help improving further care planning and care.

Evaluation of post-acute care and one-year outcomes among Medicare beneficiaries with hip fractures: a retrospective cohort study

BACKGROUND

Post-acute care (PAC) services after hospitalization for hip fracture are typically provided in skilled nursing facilities (SNFs), inpatient rehabilitation facilities (IRFs), or at home via home health care (HHC). Little is known about the clinical course following PAC for hip fracture. We examined the nationwide burden of adverse outcomes by PAC setting in the year following discharge from PAC for hip fracture.

METHODS

This retrospective cohort included Medicare Fee-for-Service beneficiaries > 65 years who received PAC services in U.S. SNFs, IRFs, or HHC following hip fracture hospitalization between 2012 and 2018. Individuals who had a fall-related injury (FRI) during PAC or received PAC services in multiple settings were excluded. Primary outcomes included FRIs, all-cause hospital readmissions, and death in the year following discharge from PAC. Cumulative incidences and incidence rates for adverse outcomes were reported by PAC setting. Exploratory analyses examined risk ratios and hazard ratios between settings before and after inverse-probability-of-treatment-weighting, which accounted for 43 covariates.

RESULTS

Among 624,631 participants (SNF, 67.78%; IRF, 16.08%; HHC, 16.15%), the mean (standard deviation) age was 82.70 (8.26) years, 74.96% were female, and 91.30% were non-Hispanic White. Crude incidence rates (95%CLs) per 1000 person-years were highest among individuals receiving SNF care for FRIs (SNF, 123 [121, 123]; IRF, 105 [102, 107]; HHC, 89 [87, 91]), hospital readmission (SNF, 623 [619, 626]; IRF, 538 [532, 544]; HHC, 418 [414, 423]), and death (SNF, 167 [165, 169]; IRF, 47 [46, 49]; HHC, 55 [53, 56]). Overall, rates of adverse outcomes generally remained higher among SNF care recipients after covariate adjustment. However, inferences about the group with greater adverse outcomes differed for FRIs and hospital readmissions based on risk ratio or hazard ratio estimates.

CONCLUSIONS

In this retrospective cohort study of individuals hospitalized for hip fracture, rates of adverse outcomes in the year following PAC were common, especially among SNF care recipients. Understanding risks and rates of adverse events can inform future efforts to improve outcomes for older adults receiving PAC for hip fracture. Future work should consider calculating risk and rate measures to assess the influence of differential time under observation across PAC groups.

Complement C1q drives microglia-dependent synaptic loss and cognitive impairments in a mouse model of lipopolysaccharide-induced neuroinflammation

Activated microglia and subsequent release of pro-inflammatory cytokines result in neuroinflammatory status which further damage neurological function including cognitive impairments in various neurological conditions. However, the underlying molecular mechanisms during these pathological processing remain unknown. In the current study, mice received intraperitoneal administrations of LPS (0.5 mg/kg, daily, Escherichia coli O55:B5) for seven consecutive days and their different cohorts were used for behavioral assessment with open field, Y maze, and novel object recognition test or for electrophysiology recordings of mEPSC, LFP or LTP in in vivo or ex vivo preparation. The hippocampus from some cohorts were harvested for immunostaining or Western blotting of c1q, Iba-1, CD68, PSD95 and dendritic spine density or for transcriptome and proteomics analysis. Repeated LPS injections induced an up-regulation of complement system protein c1q and distinct microglial phenotype with an enrichment of the complement-phagosome pathway. Microglial synaptic engulfment and profound synaptic loss were found. These pathological changes were accompanied with the significantly decreased excitatory synaptic transmission, disturbed theta oscillations, impaired hippocampal long-term potentiation, and cognitive impairments. Notably, neutralization of c1q signaling robustly prevented these changes. Collectively, our data provide evidence that activated microglia and complement cascade c1q signaling in the hippocampus may account for synaptic loss and cognitive impairments in a mouse model of neuroinflammation induced by repeated LPS injections. Our work implicates that complement system may be a therapeutic target for developing therapies to prevent or treat cognitive disorders related to neuroinflammation or other disease conditions including neurodegenerative disease per se.

Use of the Shizuoka Hip Fracture Prognostic Score (SHiPS) to Predict Long-Term Mortality in Patients With Hip Fracture in Japan: A Cohort Study Using the Shizuoka Kokuho Database

Hip fractures are common in patients of advanced age and are associated with excess mortality. Rapid and accurate prediction of the prognosis using information that can be easily obtained before surgery would be advantageous to clinical management. We performed a population-based retrospective cohort study using an 8.5-year Japanese claims database (April 2012-September 2020) to develop and validate a predictive model for long-term mortality after hip fracture. The study included 43,529 patients (34,499 [79.3%] women) aged ≥65 years with first-onset hip fracture. During the observation period, 43% of the patients died. Cox regression analysis identified the following prognostic predictors: sex, age, fracture site, nursing care certification, and several comorbidities (any malignancy, renal disease, congestive heart failure, chronic pulmonary disease, liver disease, metastatic solid tumor, and deficiency anemia). We then developed a scoring system called the Shizuoka Hip Fracture Prognostic Score (SHiPS); this system was established by scoring based on each hazard ratio and classifying the degree of mortality risk into four categories based on decision tree analysis. The area under the receiver operating characteristic (ROC) curve (AUC) (95% confidence interval [CI]) of 1-year, 3-year, and 5-year mortality based on the SHiPS was 0.718 (95% CI, 0.706-0.729), 0.736 (95% CI, 0.728-0.745), and 0.758 (95% CI, 0.747-0.769), respectively, indicating good predictive performance of the SHiPS for as long as 5 years after fracture onset. Even when the SHiPS was individually applied to patients with or without surgery after fracture, the prediction performance by the AUC was >0.7. These results indicate that the SHiPS can predict long-term mortality using preoperative information regardless of whether surgery is performed after hip fracture.

Development and validation of the fall-related injury risk in nursing homes (INJURE-NH) prediction tool

BACKGROUND

Existing models to predict fall-related injuries (FRI) in nursing homes (NH) focus on hip fractures, yet hip fractures comprise less than half of all FRIs. We developed and validated a series of models to predict the absolute risk of FRIs in NH residents.

METHODS

Retrospective cohort study of long-stay US NH residents (≥100 days in the same facility) between January 1, 2016 and December 31, 2017 (n = 733,427) using Medicare claims and Minimum Data Set v3.0 clinical assessments. Predictors of FRIs were selected through LASSO logistic regression in a 2/3 random derivation sample and tested in a 1/3 validation sample. Sub-distribution hazard ratios (HR) and 95% confidence intervals (95% CI) were estimated for 6-month and 2-year follow-up. Discrimination was evaluated via C-statistic, and calibration compared the predicted rate of FRI to the observed rate. To develop a parsimonious clinical tool, we calculated a score using the five strongest predictors in the Fine-Gray model. Model performance was repeated in the validation sample.

RESULTS

Mean (Q1, Q3) age was 85.0 (77.5, 90.6) years and 69.6% were women. Within 2 years of follow-up, 43,976 (6.0%) residents experienced ≥1 FRI. Seventy predictors were included in the model. The discrimination of the 2-year prediction model was good (C-index = 0.70), and the calibration was excellent. Calibration and discrimination of the 6-month model were similar (C-index = 0.71). In the clinical tool to predict 2-year risk, the five characteristics included independence in activities of daily living (ADLs) (HR 2.27; 95% CI 2.14-2.41) and a history of non-hip fracture (HR 2.02; 95% CI 1.94-2.12). Performance results were similar in the validation sample.

CONCLUSIONS

We developed and validated a series of risk prediction models that can identify NH residents at greatest risk for FRI. In NH, these models should help target preventive strategies.

Potential Solutions for the Mitigation of Hip Injuries Caused by Falls in Older Adults: A Narrative Review

BACKGROUND

Hip injuries caused by falling are common and often catastrophic for older adults. There is thus an urgent need to develop solutions designed to mitigate fall injuries to the hip by reducing the forces created on the body by ground impact.

METHODS

The goal of this narrative review was to synthesize published literature on available products developed with the expressed goal of reducing fall-related hip injuries.

RESULTS

Three categories were identified: passive wearables (eg, hip protectors), active wearables (eg, instrumented belts with deployable airbags), and compliant flooring. Laboratory studies indicate that each technology can reduce peak forces induced by simulated falls. Considerable preliminary data suggest that passive wearables and compliant flooring may reduce fall-related injuries within long-term care facilities. Controlled trials of specific types of these 2 technologies, however, have produced inconsistent results. While little is known about the effectiveness of active wearables, promising early data indicate the feasibility of an instrumented belt worn around the waist to effectively deploy an airbag to protect the hips prior to ground impact. Important challenges associated with one or more identified technologies included poor adherence to instructed wear as well as the potential for significant physical or time burden to caregivers or health care professionals.

CONCLUSIONS

Passive wearables, active wearables, and compliant flooring have shown promise in reducing fall-related hip injuries in older adults. Still, each type of product is accompanied by limited real-world data and/or significant challenges that must be overcome to maximize effectiveness and minimize unintended side effects.

[Translated article] One-year mortality and associated factors in patients undergoing surgery for hip fracture

INTRODUCTION

Hip fractures are very common injuries in elderly patients and are associated with increased mortality.

OBJECTIVE

To identify the factors associated with mortality in patients after one year of being operated for hip fracture in an Orthogeriatric Program.

METHODS

We design an observational analytical study in subjects older than 65 years admitted to the Hospital Universitario San Ignacio for hip fracture who were treated in the Orthogeriatrics Program. Telephone follow-up was performed one year after admission. Data were analyzed using a univariate logistic regression model and a multivariate logistic regression model was applied to control the effect of the other variables.

RESULTS

Mortality was 17.82%, functional impairment was 50.91%, and institutionalization was 13.9%. The factors associated with mortality were moderate dependence (OR=3.56, 95% CI=1.17-10.84, p=0.025), malnutrition (OR=3.42, 95% CI=1.06-11.04, p=0.039), in-hospital complications (OR=2.80, 95% CI=1.11-7.04, p=0.028), and older age (OR=1.09, 95% CI=1.03-1.15, p=0.002). The factor associated with functional impairment was a greater dependence at admission (OR=2.05, 95% CI=1.02-4.10, p=0.041), and with institutionalization was a lower Barthel index score at admission (OR=0.96, 95% CI=0.94-0.98, p=0.001).

CONCLUSIONS

Our results shows that the factors associated with mortality one year after hip fracture surgery were: moderate dependence, malnutrition, in-hospital complications and advanced age. Having previous functional dependence is directly related to greater functional loss and institutionalization.

Requests for Compensation in Cases Involving Patients' Falls in Healthcare Settings: A Retrospective Analysis

Falls are the most frequent adverse events recorded in healthcare facilities. By employing a multifaceted strategy to ensure prevention interventions that are specific to the patient type and environmental risk management, risk factor evaluation may help to reduce falls in the hospital setting. Patient falls are one of the main causes of lawsuits against hospitals, which has led to the development of validated instruments that are beneficial in treating the patient after the incident and effective in minimizing the frequency of falls. The aim of our study is to evaluate compensation claims asserting healthcare culpability in situations where a patient fell in a hospital setting. The collected data relate to judgments issued in Italy until December 2022 regarding 30 episodes of falls that occurred between 2003 and 2018. Our research revealed that approximately 50% of Italian healthcare organizations lose the case in court when a patient falls in a hospital setting and dies or is injured. In half of these cases, the failure of the medical staff to use protective equipment against falls is what led to the court's acceptance of the compensation claim. In order to improve the quality of healthcare services, fall prevention techniques must continue to be implemented.

Pain trajectories of nursing home residents

BACKGROUND

Understanding changes in nursing home (NH) resident pain over time would provide a more informed perspective, allowing opportunities to alter the course of illness, plan care, and set priorities. Therefore, the purpose of this analysis was to identify and characterize clinically meaningful, dynamic pain trajectories in NH residents.

METHODS

Retrospective longitudinal analysis of NH resident pain scores with a length of stay >100 days (N = 4864). Group-based trajectory modeling was applied to Minimum Data Set 3.0 assessments to identify pain trajectories. Trajectories were then characterized using unadjusted and adjusted cross-sectional associations between residents' demographic and clinical characteristics and their pain trajectory.

RESULTS

We identified four distinct trajectories: (1) consistent pain absence (48.9%), (2) decreasing-increasing pain presence (21.8%), (3) increasing-decreasing pain presence (15.3%), and (4) persistent pain presence (14.0%). Demographics of younger age and living in a rural area were associated with the persistent pain presence trajectory. Clinical variables of obesity and intact cognition were associated with being in the persistent pain presence trajectory. A smaller proportion of residents with moderately or severely impaired cognition were in any of the trajectory groups with pain.

CONCLUSIONS

We identified and characterized four pain trajectories among NH residents, including persistent pain presence which was associated with demographic characteristics (younger, female, rural) and clinical factors (obese, fracture, contracture). Moreover, residents with a diagnosis of Alzheimer's disease or dementia were less likely to be in any of the three trajectories with pain, likely representing the difficulty in evaluating pain in these residents. It is important that NH staff understand, recognize, and respond to the factors associated with the identified pain trajectories to improve mitigation of potentially persistent pain (e.g., hip fracture, contracture) or improve proxy pain assessment skills for residents at risk for under reporting of pain (e.g., Alzheimer's Disease).

Standardized Tip-Apex Distance (STAD): a modified individualized measurement of cephalic fixator position based on its own femoral head diameter in geriatric intertrochanteric fractures with internal fixation

OBJECTIVE

To design a standardized Tip-Apex Distance (STAD) and analyze the clinical significance of STAD in predicting cut-out in geriatric intertrochanteric fractures with internal fixation.

METHODS

Firstly, we designed STAD according to the rule of TAD. We measured the STAD individually based on its own femoral head diameter (iFHD) instead of the known diameter of the lag screw in calculating TAD, resulting in that the STAD is simply the relative quantitation relationship of iFHD (the times of iFHD). In this study, we assumed that all the iFHD was 6D (1iFHD = 6D, or 1D = 1/6 of iFHD) in order for complete match of the Cleveland zone system, easy comparison of the STAD, and convenient identification for artificial intelligence. Secondly, we calculated and recorded all the STAD of cephalic fixator in 123 eligible ITF patients. Thirdly, we grouped all the ITF patients into the Failure and Non-failure groups according to whether cut-out or not, and analyzed the correlation between the cut-out and the STAD.

RESULTS

Cleveland zone, Parker's ratio (AP), TAD, and STAD were associated with the cut-out in univariate analysis. However, only STAD was the independent predictor of the cut-out by multivariate analysis. No cut-out was observed when STAD ≤ 2D (1/3 of iFHD). The Receiver Operating Characteristic (ROC) curve indicated that STAD was a reliable predictor of cut-out, and the best cut-off value of STAD was 2.92D. Cut-out rate increased dramatically when STAD increased, especially when STAD > 3D (1/2 of iFHD).

CONCLUSION

Essentially, the STAD is a relative quantitation relationship of iFHD. The STAD is a reliable measurement of cephalic fixator position in predicting cut-out in geriatric ITF patients with single-screw cephalomedullary nail fixations. For avoiding cut-out, the STAD should be no more than a half of iFHD.

Ten existing osteoporosis prediction tools for the successful application of National Health Insurance-reimbursed anti-osteoporosis medications in long-term care residents in Taiwan

BACKGROUND/PURPOSE

Osteoporotic fracture introduce enormous societal and economic burden, especially for long-term care residents (LTCRs). Although osteoporosis prevention for LTCRs is urgently needed, obstacles such as frail status and inconvenient hospital visits hurdled them from necessary examinations and diagnoses. We aimed to test 10 existing osteoporosis screening tools (OSTs), which can be easily used in institutions and serve as a prediction, for accurately determining the outcome of a Taiwan's National Health Insurance (NHI)-reimbursed anti-osteoporosis medications (AOMs) application for LTCRs.

METHODS

This prospective analysis recruited 444 patients from LTC institutions between October 2018 and November 2019. Predictions of whether the NHI-reimbursed AOMs criteria was met were tested for 10 OSTs. The results of OSTs categorized into self-reported or validated based on previous fracture history were self-reported by LTCRs or validated by imaging data and medical records, respectively. The receiver operating characteristic curve and the optimal cut-off points for LTCRs based on Youden's index were explored.

RESULTS

Overall, the validated OSTs had a higher positive predictive value (PPV) and negative predictive value (NPV) summation than the corresponding reported OSTs. The validated FRAX-Major was the best OST (PPV = 63.6%, NPV = 82.4% for the male group and, PPV = 78.8%, NPV = 90.0% for the female group). After applying the optimum cut-off derived from Youden's index, the validated FRAX-Major (PPV = 75.4%, NPV = 92.0%)) remained performed best for men. In female population, validated FRAX-Major (PPV = 87.2%, NPV = 84.1%) and validated osteoporosis prescreening risk assessment (OPERA; PPV = 96.1%, NPV = 79.7%)) both provided good prediction results.

CONCLUSION

FRAX-Major and OPERA have better prediction ability for LTCRs to acquire NHI-reimbursed AOMs. The validated fracture history and adjusted cut-off points could prominently increase the PPV during prediction.

Impact of Dementia on Long-Term Hip Fracture Surgery Outcomes: An Electronic Health Record Analysis

OBJECTIVE

Older adults with dementia are at higher risk for sustaining hip fracture and their long-term health outcomes after surgery are usually worse than those without dementia. Widespread adoption of electronic health records (EHRs) may allow hospitals to better monitor long-term health outcomes in patients with dementia after hospitalization. This study aimed to (1) estimate how dementia influences discharge location, mortality, and readmission 180 days and 1 year after hip fracture surgery in older adults, and (2) demonstrate the feasibility of using selection-bias reduced EHR data for research and long-term health outcomes monitoring.

DESIGN

Retrospective observational cohort study using EHRs.

SETTING AND PARTICIPANTS

A cohort of 1171 patients over age 65 years who had an initial hip fracture surgery between October 2015 and December 2018 was extracted from EHRs of one health system; 376 of these patients had dementia.

METHODS

Logistic regression was applied to estimate influences of dementia on discharge disposition and Cox proportional hazards model for mortality. The Fine and Gray regression model was used to analyze readmission, accounting for the competing risk of death. To reduce selection bias in EHRs, inverse probability of treatment weighting using propensity scores was implemented before modeling.

RESULTS

Dementia had significant impacts on all outcomes: being discharged to facilities [odds ratio (OR) = 2.11, 95% confidence interval (CI) 1.19-3.74], 180-day mortality [hazard ratio (HR) = 1.69, 95% CI 1.20-2.38], 1-year mortality (HR = 1.78, 95% CI 1.33-2.38), 180-day readmission (HR = 1.62, 95% CI 1.39-1.89), and 1 year readmission (HR = 1.39, 95% CI 1.21-1.58).

CONCLUSIONS AND IMPLICATIONS

Dementia was a significant risk factor for worse long-term outcomes. The inverse probability of treatment weighting approach can be used to reduce selection bias in EHR data for research and monitoring long-term health outcomes in the target population. Such monitoring could foster collaborations with post-acute and long-term health care services to improve recovery outcomes in patients with dementia after hip fracture surgery.

Osteoporosis-related appendicular fractures in Tikur Anbessa Specialized Hospital, Ethiopia: a prospective observational study

We examined the frequency of osteoporotic fractures among patients presenting to Tikur Anbessa Specialized Hospital. Osteoporotic fractures accounted for 10.4% of all fractures and 31.8% of those 40 years and older. In addition, hip fractures accounted for 60%. Therefore, devising strategies for preventing, treating, and rehabilitating osteoporotic fractures is critical.

PURPOSE

Examine the frequency of osteoporotic fractures among patients presenting to Tikur Anbessa Specialized Hospital.

METHODS

This is an observational study of prospectively collected data between January 2018 and December 2021. Patients were categorized as having osteoporotic fracture if they were 40 years or older, sustained a low-energy injury, and had characteristic fracture patterns to the hip, proximal humerus, distal radius, tibia (in females only), clavicle, and scapula. A descriptive analysis was carried out to assess patient demographics. Risk factors were then evaluated using a binary logistic regression model.

RESULTS

A total of 4712 orthopedic injury patients presented to the emergency department with 4422 fracture cases. Of these, 461 fulfilled the diagnostic criteria for osteoporotic fractures. The overall rate of osteoporotic fractures was 10.4% of all patients with fractures and 31.8% of those 40 years or older. Overall, 63.3% were female. One in four females and 5% of males with musculoskeletal trauma had an osteoporotic fracture. Osteoporotic hip fractures made up 59.9% of osteoporotic fractures and 5.9% of all fractures, followed by distal radius (23%), tibia in females (8.2%), and proximal humerus (7.4%). Pelvis (2.6%), clavicle (0.9%), and scapula (0.2%) fractures were found to be rare. Among all patients with fractures following low-energy injuries, when patients were aged 50 years and older, there was a higher risk that the trauma resulted in an osteoporotic fracture. This figure was highest among those aged 80 years and older (odds ratio (OR), 11.88; 95% CI, 7.01-20.11).

CONCLUSIONS

Further studies need to be done to show the prevalence of osteoporosis and osteoporotic fractures in Ethiopia and examine risk factors. Devising strategies for preventing, treating, and rehabilitating osteoporotic fractures is critical.

Predictors of Hospice Discharge After Surgical Fixation of Hip Fractures

BACKGROUND

Each year, over 300,000 people older than 65 years are hospitalized for hip fractures. Given the notable morbidity and mortality faced by elderly patients in the postinjury period, recommendations have been put forth for integrating palliative and, when needed, hospice care to improve patients' quality of life. Our objective was to (1) understand the proportion of patients discharged to hospice after hip fracture surgery and their 30-day mortality rates and (2) identify the independent predictors of discharge to hospice.

METHODS

We retrospectively queried the American College of Surgeons National Surgical Quality Improvement Program for all hip fracture surgeries between the years of 2016 and 2018. Included cases were stratified into two cohorts: cases involving a discharge to hospice and nonhospice discharge. Variables assessed included patient demographics, comorbidities, perioperative characteristics, and postoperative outcomes. Differences between hospice and nonhospice patients were compared using chi-squared analysis or the Fisher exact test for categorical variables and Student t -tests for continuous variables. A binary logistic regression model was used to assess independent predictors of hospice discharge with 30-day mortality.

RESULTS

Overall, 31,531 surgically treated hip fractures were identified, of which only 281 (0.9%) involved a discharge to hospice. Patients discharged to hospice had a 67% 30-day mortality rate in comparison with 5.6% of patients not discharged to hospice ( P < 0.001). Disseminated cancer, dependent functional status, >10% weight loss over 6 months preoperatively, and preoperative cognitive deficit were the strongest predictors of hospice discharge with 30-day mortality after hip fracture surgery.

CONCLUSIONS

Current hospice utilization in hip fracture patients remains low, but 30-day mortality in these patients is high. An awareness of the associations between patient characteristics and discharge to hospice with 30-day mortality is important for surgeons to consider when discussing postoperative expectations and outcomes with these patients.

One-year mortality and associated factors in patients undergoing surgery for hip fracture

INTRODUCTION

Hip fractures are very common injuries in elderly patients and are associated with increased mortality.

OBJECTIVE

To identify the factors associated with mortality in patients after one year of being operated for hip fracture in an Orthogeriatric Program.

METHODS

We design an observational analytical study in subjects older than 65 years admitted to the Hospital Universitario San Ignacio for hip fracture who were treated in the Orthogeriatrics Program. Telephone follow-up was performed one year after admission. Data were analyzed using a univariate logistic regression model and a multivariate logistic regression model was applied to control the effect of the other variables.

RESULTS

Mortality was 17.82%, functional impairment was 50.91%, and institutionalization was 13.9%. The factors associated with mortality were moderate dependence (OR=3.56, 95% CI=1.17-10.84, p=0.025), malnutrition (OR=3.42, 95% CI=1.06-11.04, p=0.039), in-hospital complications (OR=2.80, 95% CI=1.11-7.04, p=0.028), and older age (OR=1.09, 95% CI=1.03-1.15, p=0.002). The factor associated with functional impairment was a greater dependence at admission (OR=2.05, 95% CI=1.02-4.10, p=0.041), and with institutionalization was a lower Barthel index score at admission (OR=0.96, 95% CI=0.94-0.98, p=0.001).

CONCLUSIONS

Our results shows that the factors associated with mortality one year after hip fracture surgery were: moderate dependence, malnutrition, in-hospital complications and advanced age. Having previous functional dependence is directly related to greater functional loss and institutionalization.

Controversies in Osteoporosis Treatment of Nursing Home Residents

Osteoporotic fractures are a common and serious health problem for older adults living in nursing homes (NHs). Risk of fracture increases with age and dementia status, yet gaps in evidence result in controversies around when to start and stop treatment for osteoporosis in NH residents, particularly those who have high fracture risk but have limited life expectancy. In this article, we discuss these areas of controversy. We provide an overview of current guidelines that explicitly address osteoporosis treatment strategies for NH residents, review the evidence for osteoporosis medications in NH residents, and use these sources to suggest practical recommendations for clinical practice and for research. Three published guidelines (from the United States, Canada, and Australia) and several studies provide the current basis for clinical decisions about osteoporosis treatment for NH residents. Practical approaches may include broad use of vitamin D and selective use of osteoporosis medication based on risks, benefits, and goals of care. Clinicians still lack strong evidence to guide treatment of NH residents with advanced dementia, multimorbidity, or severe mobility impairment. Future priorities for research include identifying optimal approaches to risk stratification and prevention strategies for NH residents and evaluating the risk-benefit profile of pharmacologic treatments for osteoporosis NH residents across key clinical strata. In the absence of such evidence, decisions for initiating and continuing treatment should reflect a patient-centered approach that incorporates life expectancy, goals of care, and the potential burden of treatment.

Perioperative Management and Outcomes of Hip Fracture Patients with Advanced Chronic Kidney Disease

Aims

To explore clinical characteristics, perioperative management and outcomes of Hip Fracture patients with advanced Chronic Kidney Disease (HF-aCKD) compared to the general Hip Fracture population without aCKD (HF-G) within a large volume tertiary hospital in Western Australia.

Methods

Retrospective chart review of patients admitted with hip fracture (HF) to a single large volume tertiary hospital registered on Australian and New Zealand Hip Fracture Registry (ANZHFR). We compared baseline demographic and clinical frailty scale (CFS) of HF-aCKD (n = 74), defined as eGFR < 30 mls/min/1.73 m2, with HF-G (n = 452) and determined their outcomes at 120 days.

Results

We identified 74 (6.97%) HF patients with aCKD. General demographics were similar in HF-aCKD and HF-G populations. 120-days mortality for HF-aCKD was double that of HF-G population (34% vs 17%, P = .001). For dialysis patients, 120-days mortality was triple that of HF-G population (57%). Except for the fit category of HF-aCKD group, higher CFS was associated with higher 120-days mortality in both groups. Of all HF-aCKD patients, 96% had operative intervention and 48% received blood transfusion. There were no new starts to dialysis peri-operatively. Each point reduction in eGFR below 12 mL/min/1.73 m2 was associated with 3% increased probability of death in hospital.

Conclusions

120-days mortality was double in HF-aCKD and triple in HF-dialysis that of the HF-G within our institution. Clinical frailty scale can be useful in predicting mortality after HF in frail aCKD patients. High rate of blood transfusions was observed in HF-aCKD group. Further studies with larger HF-aCKD numbers are required to explore these associations in detail.

Association between hyperglycemia on admission and preoperative deep venous thrombosis in patients with femoral neck fractures

Background

Elevated blood glucose is the most frequent electrolyte disturbance in acutely ill patients. This study aimed to determine whether admission hyperglycemia is associated with the incidence of preoperative deep venous thrombosis (DVT) in patients with femoral neck fractures.

Methods

This retrospective study was conducted on consecutive patients with femoral neck fractures admitted to our institution from March 2018 to March 2022. Blood glucose levels were measured within 24 h of admission and categorized into quartiles (Q1 = 5.30; Q2 = 5.70; Q3 = 6.60). Patients were divided into four groups (Group1-4) based on the quartiles. Preoperative DVT was diagnosed using venous compression ultrasonography. Multivariable logistic regression models and propensity score matching analysis evaluated the association between blood glucose and preoperative DVT in patients.

Results

Of 217 patients included in this study, 21(9.7%) had preoperative DVT in hospital, and admission hyperglycemia was observed in 83 (38.2%). Preoperative DVT was higher in patients with hyperglycemia (n = 15) than patients without hyperglycemia (n = 6) in the multivariable logistic regression models (OR 3.03, 95% CI 0.77–11.87). Propensity scores matching analyses manifested that compared with patients with group 2 (5.30 – 5.70 mmol/L) of glucose levels, the odds of preoperative DVT were slightly higher (OR 1.94, 95% CI 0.31–12.12) in patients with group 3 (5.70 – 6.60 mmol/L), substantially higher (OR 6.89, 95% CI 1.42–33.44, P trend < 0.01) in patients with the group 4 (> 6.60 mmol/L) of glucose levels.

Conclusions

In patients hospitalized for femoral neck fracture, markedly elevated blood glucose is associated with increased preoperative DVT in patients. The development of this biomarker could help in guiding patient counseling, risk assessment, and future management decisions.

Post-Fracture Inpatient and Outpatient Physical/Occupational Therapy and Its Association with Survival among Adults with Cerebral Palsy

Physical and/or occupational therapy (PT/OT) may improve post-fracture health and survival among adults with cerebral palsy (CP), but this has not been studied in the inpatient setting. The objective was to quantify the association between acute inpatient and outpatient PT/OT use with 1-year mortality among adults with CP. This was a retrospective cohort study of adults with CP with an incident fragility fracture admitted to an acute care or rehabilitation facility using a random 20% Medicare fee-for-service dataset. Acute care/rehabilitation PT/OT was measured as the average PT/OT cost/day for the length of stay (LOS). Weekly exposure to outpatient PT/OT was examined up to 6 months post-fracture. Cox regression examined the adjusted association between the interaction of acute care/rehabilitation average PT/OT cost/day and LOS with 1-year mortality. A separate Cox model added time-varying outpatient PT/OT. Of 649 adults with CP, average PT/OT cost/day was associated with lower mortality rate for LOS < 17 days (HR range = 0.78−0.93), and increased mortality rate for LOS > 27 days (HR ≥ 1.08) (all, p < 0.05). After acute care/rehabilitation, 44.5% initiated outpatient PT/OT, which was associated with lower mortality rate (HR = 0.52; 95% CI = 0.27−1.01). Post-fracture inpatient and outpatient PT/OT were associated with improved 1-year survival among adults with CP admitted to acute care/rehabilitation facilities.

Association of Medicare bundled payment model with joint replacement care for people with dementia

BACKGROUND

We examined whether the Comprehensive Care for Joint Replacement (CJR) model was associated with changes in the receipt of joint replacement among people with Alzheimer's disease and related dementias (ADRD) as well as spending, health service use, and postsurgical outcomes among people with ADRD who underwent a joint replacement surgery.

METHODS

Retrospective cohort study using 2013-2017 Medicare claims and Minimum Data Set. We used a difference-in-differences analysis to compare people with ADRD residing in CJR-participating treatment areas versus nonparticipating control areas on the receipt of joint replacement, episode spending during the index hospitalization and subsequent 90-day post-discharge period, discharges to an institutional post-acute care setting, and readmissions within 90 days of hospital discharge.

RESULTS

Our sample included 3,361,950 Medicare enrollees with ADRD (2,156,995 women [64%]; mean [SD] age, 83 [8.0] years; 2,646,405 white [78%], 344,478 black [10%], 224,010 Hispanic [7%]). The receipt of replacement among people with ADRD changed similarly between CJR-participating treatment and control areas after CJR model was implemented, suggesting no association of CJR model with the receipt of replacement. Among people with ADRD who received joint replacement, the CJR model was associated with a $1029 decrease in spending per episode (95% confidence interval [CI] -$1577, -$481, p < 0.001), a 1.62 percentage point decrease in discharges to an institutional post-acute care setting (95% CI -3.17, -0.07, p = 0.04), but no changes in 90-day readmission (95% CI -2.68, 0.00, p = 0.051).

CONCLUSIONS

Despite concerns that the CJR model could hinder people with ADRD from receiving joint replacement, the receipt of joint replacement did not change among people with ADRD under CJR. The CJR model was associated with decreased spending for people with ADRD who received joint replacements, driven by reduced discharges to an institutional post-acute care setting, without any changes in 90-day readmission.

Development and Validation of Indicators for Population Injury Surveillance in Hong Kong: Development and Usability Study

BACKGROUND

Injury is an increasingly pressing global health issue. An effective surveillance system is required to monitor the trends and burden of injuries.

OBJECTIVE

This study aimed to identify a set of valid and context-specific injury indicators to facilitate the establishment of an injury surveillance program in Hong Kong.

METHODS

This development of indicators adopted a multiphased modified Delphi research design. A literature search was conducted on academic databases using injury-related search terms in various combinations. A list of potential indicators was sent to a panel of experts from various backgrounds to rate the validity and context-specificity of these indicators. Local hospital data on the selected core indicators were used to examine their applicability in the context of Hong Kong.

RESULTS

We reviewed 142 articles and identified 55 indicators, which were classified into 4 domains. On the basis of the ratings by the expert panel, 13 indicators were selected as core indicators because of their good validity and high relevance to the local context. Among these indicators, 10 were from the construct of health care service use, and 3 were from the construct of postdischarge outcomes. Regression analyses of local hospitalization data showed that the Hong Kong Safe Community certification status had no association with 5 core indicators (admission to intensive care unit, mortality rate, length of intensive care unit stay, need for a rehabilitation facility, and long-term behavioral and emotional outcomes), negative associations with 4 core indicators (operative intervention, infection rate, length of hospitalization, and disability-adjusted life years), and positive associations with the remaining 4 core indicators (attendance to accident and emergency department, discharge rate, suicide rate, and hospitalization rate after attending the accident and emergency department). These results confirmed the validity of the selected core indicators for the quantification of injury burden and evaluation of injury-related services, although some indicators may better measure the consequences of severe injuries.

CONCLUSIONS

This study developed a set of injury outcome indicators that would be useful for monitoring injury trends and burdens in Hong Kong.

Shared decision-making for the treatment of proximal femoral fractures in frail institutionalised older patients: healthcare providers' perceived barriers and facilitators

INTRODUCTION

Proximal femoral fractures are common in frail institutionalised older patients. No convincing evidence exists regarding the optimal treatment strategy for those with a limited pre-fracture life expectancy, underpinning the importance of shared decision-making (SDM). This study investigated healthcare providers' barriers to and facilitators of the implementation of SDM.

METHODS

Dutch healthcare providers completed an adapted version of the Measurement Instrument for Determinants of Innovations questionnaire to identify barriers and facilitators. If ≥20% of participants responded with 'totally disagree/disagree', items were considered barriers and, if ≥80% responded with 'agree/totally agree', items were considered facilitators.

RESULTS

A total of 271 healthcare providers participated. Five barriers and 23 facilitators were identified. Barriers included the time required to both prepare for and hold SDM conversations, in addition to the reflective period required to allow patients/relatives to make their final decision, and the number of parties required to ensure optimal SDM. Facilitators were related to patients' values, wishes and satisfaction, the importance of SDM for patients/relatives and the fact that SDM is not considered complex by healthcare providers, is considered to be part of routine care and is believed to be associated with positive patient outcomes.

CONCLUSION

Awareness of identified facilitators and barriers is an important step in expanding the use of SDM. Implementation strategies should be aimed at managing time constraints. High-quality evidence on outcomes of non-operative and operative management can enhance implementation of SDM to address current concerns around the outcomes.

Identification of Fall-Related Injuries in Nursing Home Residents Using Administrative Claims Data

BACKGROUND

Fall-related injuries (FRIs) are a leading cause of morbidity, mortality, and costs among nursing home (NH) residents. Carefully defining FRIs in administrative data is essential for improving injury-reduction efforts. We developed a series of novel claims-based algorithms for identifying FRIs in long-stay NH residents.

METHODS

This is a retrospective cohort of residents of NH residing there for at least 100 days who were continuously enrolled in Medicare Parts A and B in 2016. FRIs were identified using 4 claims-based case-qualifying (CQ) definitions (Inpatient [CQ1], Outpatient and Provider with Procedure [CQ2], Outpatient and Provider with Fall [CQ3], or Inpatient or Outpatient and Provider with Fall [CQ4]). Correlation was calculated using phi correlation coefficients.

RESULTS

Of 153 220 residents (mean [SD] age 81.2 [12.1], 68.0% female), we identified 10 104 with at least one FRI according to one or more CQ definition. Among 2 950 residents with hip fractures, 1 852 (62.8%) were identified by all algorithms. Algorithm CQ4 (n = 326-2 775) identified more FRIs across all injuries while CQ1 identified less (n = 21-2 320). CQ2 identified more intracranial bleeds (1 028 vs 448) than CQ1. For nonfracture categories, few FRIs were identified using CQ1 (n = 20-488). Of the 2 320 residents with hip fractures identified by CQ1, 2 145 (92.5%) had external cause of injury codes. All algorithms were strongly correlated, with phi coefficients ranging from 0.82 to 0.99.

CONCLUSIONS

Claims-based algorithms applied to outpatient and provider claims identify more nonfracture FRIs. When identifying risk factors, stakeholders should select the algorithm(s) suitable for the FRI and study purpose.

Prognosis and institutionalization of frail community-dwelling older patients following a proximal femoral fracture: a multicenter retrospective cohort study

Hip fractures are a serious public health issue with major consequences, especially for frail community dwellers. This study found a poor prognosis at 6 months post-trauma with regard to life expectancy and rehabilitation to pre-fracture independency levels. It should be realized that recovery to pre-trauma functioning is not a certainty for frail community-dwelling patients.

INTRODUCTION

Proximal femoral fractures are a serious public health issue in the older patient. Although a significant rise in frail community-dwelling elderly is expected because of progressive aging, a clear overview of the outcomes in these patients sustaining a proximal femoral fracture is lacking. This study assessed the prognosis of frail community-dwelling patients who sustained a proximal femoral fracture.

METHODS

A multicenter retrospective cohort study was performed on frail community-dwelling patients with a proximal femoral fracture who aged over 70 years. Patients were considered frail if they were classified as American Society of Anesthesiologists score ≥ 4 and/or a BMI < 18.5 kg/m² and/or Functional Ambulation Category ≤ 2 pre-trauma. The primary outcome was 6-month mortality. Secondary outcomes were adverse events, health care consumption, rate of institutionalization, and functional recovery.

RESULTS

A total of 140 out of 2045 patients matched the inclusion criteria with a median age of 85 (P₂₅-P₇₅ 80-89) years. The 6-month mortality was 58 out of 140 patients (41%). A total of 102 (73%) patients experienced adverse events. At 6 months post-trauma, 29 out of 120 (24%) were readmitted to the hospital. Out of the 82 surviving patients after 6 months, 41 (50%) were unable the return to their home, and only 32 (39%) were able to achieve outdoor ambulation.

CONCLUSION

Frail community-dwelling older patients with a proximal femoral fracture have a high risk of death, adverse events, and institutionalization and often do not reobtain their pre-trauma level of independence. Foremost, the results can be used for realistic expectation management.

Incidence of potentially disruptive medical and social events in older adults with and without dementia

BACKGROUND

Potentially disruptive medical, surgical, and social events-such as pneumonia, hip fracture, and widowhood-may accelerate the trajectory of decline and impact caregiving needs in older adults, especially among people with dementia (PWD). Prior research has focused primarily on nursing home residents with dementia. We sought to assess the incidence of potentially disruptive events in community-dwelling people with and without dementia.

METHODS

Retrospective cohort study of participants aged 65+ enrolled in the Health and Retirement Study between 2010 and 2018 (n = 9346), including a subset who were married-partnered at baseline (n = 5105). Dementia was defined with a previously validated algorithm. We calculated age-adjusted and gender-stratified incidence per 1000 person-years and incidence rate ratios of: 1) hospitalization for pneumonia, 2) hip fracture, and 3) widowhood in people with and without dementia.

RESULTS

PWD (n = 596) were older (mean age 84 vs. 75) and a higher proportion were female (67% vs. 57%) than people without dementia (PWoD) (n = 8750). Age-adjusted incidence rates (per 1000 person-years) of pneumonia were higher in PWD (113.1; 95% CI 94.3, 131.9) compared to PWoD (62.1; 95% CI 54.7, 69.5), as were hip fractures (12.3; 95% CI 9.1, 15.6 for PWD compared to 8.1; 95% CI 6.9, 9.2 in PWoD). Point estimates of widowhood incidence were slightly higher for PWD (25.3; 95% CI 20.1, 30.5) compared to PWoD (21.9; 95% CI 20.3, 23.5), but differences were not statistically significant. The association of dementia with hip fracture-but not pneumonia or widowhood-was modified by gender (male incidence rate ratio [IRR] 2.24, 95% CI 1.34, 3.75 versus female IRR 1.31 95% CI 0.92,1.86); interaction term p = 0.02).

CONCLUSIONS

Compared to PWoD, community-dwelling PWD had higher rates of pneumonia and hip fracture, but not widowhood. Knowing how often PWD experience these events can aid in anticipatory guidance and care planning for this growing population.

Morbidity and Mortality After Second Hip Fracture With and Without Nursing Care Program

Background

Hip fractures are an increasingly common injury among older people who usually experience significantly worse mobility, independence in function, health, quality of life, and high rates of institutionalization. Studies have shown that only 40-60% of participants recover their pre-fracture level of mobility and ability to perform instrumental activities of daily living, while for those who are independent in self-care prior to the fracture, 20-60% still require assistance for various tasks one or two years after the fracture. As the cumulative incidence of a second hip fracture has been estimated to reach 8.4%, prevention of the second hip fracture is a major concern of the health system and the society focused mainly on lifestyle modifications, osteoporotic treatment, and fall-prevention strategies. The aim of the present study was to compare morbidity/mortality, functional results, and type of recovery between the first and second hip fractures in elderly patients.

Methods

Patients with a contralateral hip fracture were prospectively recruited during a three-year period (2016-2019). Level of independence, gait aids, type of rehabilitation, American Society of Anesthesiologists (ASA) physical status, Harris Hip Score (HHS), and Western Ontario and McMaster Universities Arthritis Index (WOMAC) scale were evaluated at admission for the second fracture and at the last reexamination.

Results

Twenty-seven out of 33 patients, aged 87.93±6.6, underwent surgery for contralateral hip fracture and followed up for 42.52±16.46 months; the mean interval between the two fractures was 39.63 months. The HHS averaged 86.19±12.18 and 59.01±32.83 and the WOMAC 86.37±12.09 and 68.22±26.18 before and after the second fracture, respectively. The mortality rate was 37.03%, 14.8±12.93 months after the second operation, with a significant relationship between the mortality time and the interval between fractures (p=0.028). Twelve and 14 of the patients received geriatric nursing care after the first and second fracture, respectively, without significant improvement in their functional results compared to home care. Mobility of nursing care patients after the second fracture was significantly improved (p=0.019).

Conclusions

Mortality is higher in the second year after the second hip fracture and strongly correlated with the time interval between fractures. A higher possibility to return in previous mobility status occurs after geriatric nursing care. 

Risk Factors of Postoperative Delirium in Elderly Patients With Intertrochanteric Fracture: An Age-Stratified Retrospective Analysis of 2307 Patients

BACKGROUND

Postoperative delirium (POD) is a serious and common complication of intertrochanteric fracture (IF). However, the risk factors for POD remain debated. The purpose of this study was to explore risk factors for POD after IF surgery in elderly patients by age-stratified analysis.

METHODS

A total of 2307 patients who underwent IF surgery in our hospital between Jan. 2017 and Nov. 2020 were included. 128 patients suffering from POD were regarded as the delirium group (DG) and the other patients as the normal group (NG). Univariate and multivariate analyses were conducted.

RESULTS

In our study, the occurrence of POD after IF surgery in elderly patients was 5.55% (128 of 2307). The results of univariate and multivariate analysis showed that advanced age and patients with a history of dementia were identified as the risk factors for POD. Age-stratified analysis showed different comorbidities influencing POD at different stages of age. Additionally, POD markedly increased along with age. Moreover, compared with younger than 70 years in male patients and younger than 80 years in female patients, patients over the age of 70 for males and over the age of 80 for females had a higher rate of POD.

CONCLUSIONS

Advanced age and patients with a history of dementia were independent risks of delirium after IF surgery in both univariate and multivariate analyses. 70 years old in male patients and 80 years old in female patients may be the cut-off values for a significantly increased rate of POD. Preoperative measures should be taken to lower the incidence of POD.

Hip fracture predicts subsequent hip fracture: a retrospective observational study to support a call to early hip fracture prevention efforts in post-fracture patients

In this real-world retrospective cohort, subsequent hip fracture occurred in one in four patients with any initial fracture, most often after hip fracture, on average within 1.5 years. These data support the need for early post-fracture interventions to help reduce imminent hip fracture risk and high societal and humanistic costs.

PURPOSE

This large retrospective cohort study aimed to provide hip fracture data, in the context of other fractures, to help inform efforts related to hip fracture prevention focusing on post-fracture patients.

METHODS

A cohort of 115,776 patients (72.3% female) aged > 65 (median age 81) with an index fracture occurring at skeletal sites related to age-related bone loss between January 1, 2011, and March 31, 2015, was identified using health services data from Ontario, Canada, and followed until March 31, 2017.

RESULTS

Hip fracture was the most common second fracture (27.8%), occurring in ≥ 19% of cases after each index fracture site and most frequently (33.0%) after hip index fracture. Median time to a second fracture of the hip was ~ 1.5 years post-index event. Patients with index hip fracture contributed the most to fracture-related initial surgeries (64.1%) and post-surgery complications (71.9%) and had the second-highest total mean healthcare cost per patient in the first year after index fracture ($62,793 ± 44,438). One-year mortality (any cause) after index hip fracture was 26.2% vs. 15.9% in the entire cohort, and 25.9% after second hip fracture.

CONCLUSION

A second fracture at the hip was observed in one in four patients after any index fracture and in one in three patients with an index hip fracture, on average within 1.5 years. Index hip fracture was associated with high mortality and post-surgery complication rates and healthcare costs relative to other fractures. These data support focusing on early hip fracture prevention efforts in post-fracture patients.

Cognitive Impairment as the Principal Factor Correlated with the Activities of Daily Living Following Hip Fracture in Elderly People

Objectives:

Hip fracture is a common injury occurring in elderly people and often impairs their activities of daily living (ADL). This study aimed to identify and analyze factors associated with ADL following hip fracture treatment.

Methods:

A total of 371 consecutive patients with hip fractures who were surgically treated in our hospital were enrolled. Among these, 103 patients who underwent acute- to recovery-phase postoperative rehabilitation at our hospital and whose motor scale of the functional independence measure (mFIM) score was ≥70 before the fracture were finally included in this study. Single and multiple regression analyses were performed to identify the factors correlated with ADL. The mFIM at hospital discharge was set as the outcome variable, and various clinical factors, such as fracture type, surgical technique, serum and biological data, mini-mental state examination (MMSE) score, and serial mFIM scores, were used as explanatory variables.

Results:

Only MMSE and preinjury mFIM scores were significantly correlated with mFIM at discharge, and MMSE had the larger effect on the outcome. Receiver operating characteristic curve analysis revealed an MMSE cutoff value of 20/21. Patients with an MMSE score of ≤20 showed a relatively poor recovery of mFIM from 2–3 weeks postoperatively compared with those with an MMSE score of ≥21.

Conclusion:

Cognitive impairment and the preinjury ADL level were correlated with short-term ADL outcomes following hip fracture. Cognitive impairment was the most important factor affecting ADL; treatment and postoperative rehabilitation should be carefully considered for cognitively disturbed patients from the acute phase after hip fracture.

Subcutaneous fat area at the upper thigh level is a useful prognostic marker in the elderly with femur fracture

BACKGROUND

The aim of this study was to evaluate prognostic value of body tissue composition at the upper thigh level for 1 year mortality in elderly patients with proximal femur fracture.

METHODS

This retrospective cohort study included consecutive elderly (aged ≥65) patients diagnosed with proximal femur fracture based on the findings of pelvic bone computed tomography (CT) performed at the emergency department of a tertiary care hospital and treated with surgery between 2010 and 2017. The cross-sectional area of subcutaneous fat and skeletal muscle at the upper thigh level was measured using CT. Adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for 1 year mortality were estimated using a Cox proportional hazards model. Survival based on the SFA quartiles was assessed using nonparametric Kaplan-Meier survival analysis and compared used log-rank tests.

RESULTS

Among 876 elderly patients included in this study, the median age was 79.0 years, and 646 (73.7%) patients were female. A total of 93 (10.6%) died within 1 year after admission to the emergency department. Survivors had a significantly higher median subcutaneous fat area (SFA) than non-survivors (170.2 vs. 133.0 cm² , P < 0.001), but no significant difference was observed between the skeletal muscle area (median, 156.7 vs. 160.3 cm² , P = 0.504) and muscle density (median, 19.0 vs. 19.1 HU, P = 0.861) of both groups. After adjustment of other clinical characteristics and body compositions, the multivariate Cox proportional hazard analysis showed that SFA (adjusted HR, 0.987; 95% CI, 0.982-0.992; P < 0.001) was independently associated with 1 year mortality. With 384 deaths during 51 322 person-months of follow-up, the median estimated survival duration of all the patients was 92.8 months (95% CI, 80.8-104.7 months). The patients with SFA in the third (165.6-195.0 cm² ) and fourth (>195.0 cm² ) quartiles showed significantly longer survival duration than those with SFA in the first (<131.4 cm² ; median survival time, 51.3 months) and second (131.4-165.5 cm² ; median survival time, 88.7 months) quartiles (P < 0.001 by log-rank test).

CONCLUSIONS

The SFAs measured at the upper thigh level and 1 year mortality are positively associated in elderly patients with proximal femur fracture. SFA may be an independent prognostic biomarker for 1 year mortality of femur fracture.

Long-term survival in high-risk older adults following emergency general surgery admission

BACKGROUND

Emergency general surgery (EGS) conditions are increasingly common among nursing home residents. While such patients have a high risk of in-hospital mortality, long-term outcomes in this group are not well described, which may have implications for goals of care discussions. In this study, we evaluate long-term survival among nursing home residents admitted for EGS conditions.

METHODS

We performed a population-based, retrospective cohort study of nursing home residents (65 years or older) admitted for one of eight EGS diagnoses (appendicitis, cholecystitis, strangulated hernia, bowel obstruction, diverticulitis, peptic ulcer disease, intestinal ischemia, or perforated viscus) from 2006 to 2018 in a large regional health system. The primary outcome was 1-year survival. To ascertain the effect of EGS admission independent of baseline characteristics, patients were matched to nursing home residents without an EGS admission based on demographics and baseline health. Kaplan-Meier analysis was used to evaluate survival across groups.

RESULTS

A total of 7,942 nursing home residents (mean age, 85 years) were admitted with an EGS diagnosis and matched to controls. One quarter of patients underwent surgery, and 18% died in hospital. At 1 year, 55% of cases were alive, compared with 72% of controls (p < 0.001). Among those undergoing surgery, 61% were alive at 1 year, compared with 72% of controls (p < 0.001). The 1-year survival probability was 57% in patients who did not require mechanical ventilation, 43% in those who required 1 to 2 days of ventilation, and 30% in those who required ≥3 days of ventilation.

CONCLUSION

Although their risk of in-hospital mortality is high, most nursing home residents admitted for an EGS diagnosis survive at least 1 year. While nursing home residents presenting with an EGS diagnosis should be cited realistic odds for the risk of death, long-term survival is achievable in the majority of these patients.
