Fragmentation of Care After Geriatric Trauma: A Nationwide Analysis of outcomes and Predictors

The health care system for the elderly is fragmented, that is worsened when readmission occurs to different hospitals. There is limited investigation into the impact of fragmentation on geriatric trauma patient outcomes. The aim of this study was to compare the outcomes following readmissions after geriatric trauma. The Nationwide Readmissions Database (2016-2017) was queried for elderly trauma patients (aged ≥65 years) readmitted due to any cause. Patients were divided into 2 groups according to readmission: index vs non-index hospital. Outcomes were 30 and 180-day complications, mortality, and the number of subsequent readmissions. Multivariable logistic regression was performed to analyze the independent predictors of fragmentation of care. A total of 36,176 trauma patients were readmitted, of which 3856 elderly patients (aged ≥65 years) were readmitted: index hospital (3420; 89%) vs non-index hospital (436; 11%). Following 1:2 propensity matching, elderly with non-index hospital readmission had higher rates of death and MI within 180 days (P = .01 and .02, respectively). They had statistically higher 30 and 180-day pneumonia (P < .01), CHF (P < .01), arrhythmias (P < .01), MI (P < .01), sepsis (P < .01), and UTI (P < .01). On multivariable binary logistic regression analysis, pneumonia (OR 1.70, P = .03), congestive heart failure (CHF) (OR 1.80, P = .03), female gender (OR .72, P = .04), and severe Head and Neck trauma (AIS≥3) (OR 1.50, P < .01) on index admission were independent predictors of fragmentation of care. While the increase in time to readmission (OR 1.01, P < .01) was also associated independently with non-index hospital admission. Fragmented care after geriatric trauma could be associated with higher mortality and complications.

Geriatric trauma: there is more to it than just the implant!

Geriatric trauma continues to rise, corresponding with the continuing growth of the older population. These fractures continue to expand, demonstrated by the incidence of hip fractures having grown to 1.5 million adults worldwide per year. This patient population and their associated fracture patterns present unique challenges to the surgeon, as well as having a profound economic impact on the health care system. Pharmacologic treatment has focused on prevention, with aging adults having impaired fracture healing in addition to diminished bone mineral density. Intraoperatively, novel ideas to assess fracture reduction to facilitate decreased fracture collapse have recently been explored. Postoperatively, pharmacologic avenues have focused on future fracture prevention, while shared care models between geriatrics and orthopaedics have shown promise regarding decreasing mortality and length of stay. As geriatric trauma continues to grow, it is imperative that we look to optimize all phases of care, from preoperative to postoperative.

A component-based analysis of metabolic syndrome's impact on 30-day outcomes after hip fracture: reduced mortality in obese patients

Introduction

Hip fractures are a common injury associated with significant morbidity and mortality. In the United States, there has been a rapid increase in the prevalence of metabolic syndrome (MetS), a condition comprised several common comorbidities, including obesity, diabetes mellitus, and hypertension, that may worsen perioperative outcomes. This article assesses the impact of MetS and its components on outcomes after hip fracture surgery.

Methods

Patients who underwent nonelective operative treatment for traumatic hip fractures were identified in the 2015-2020 American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. Baseline characteristics between groups were compared, and significant differences were included as covariates. Multivariate regression was performed to assess the impact of characteristics of interest on postoperative outcomes. Patients with MetS, or a single one of its constitutive components-hypertension, diabetes, and obesity-were compared with metabolically healthy cohorts.

Results

In total 95,338 patients were included. Patients with MetS had increased complications (OR 1.509; P < 0.001), but reduced mortality (OR 0.71; P < 0.001). Obesity alone was also associated with increased complications (OR 1.14; P < 0.001) and reduced mortality (OR 0.736; P < 0.001). Both hypertension and diabetes alone increased complications (P < 0.001) but had no impact on mortality. Patients with MetS did, however, have greater odds of adverse discharge (OR 1.516; P < 0.001), extended hospital stays (OR 1.18; P < 0.001), and reoperation (OR 1.297; P = 0.003), but no significant difference in readmission rate.

Conclusion

Patients with MetS had increased complications but decreased mortality. Our component-based analysis showed had obesity had a similar effect: increased complications but lower mortality. These results may help surgeons preoperatively counsel patients with hip fracture about their postoperative risks.

Fix or Replace? Patient Preferences for the Treatment of Geriatric Lower Extremity Fractures: A Discrete Choice Experiment

Introduction

When considering treatment options for geriatric patients with lower extremity fractures, little is known about which outcomes are prioritized by patients. This study aimed to determine the patient preferences for outcomes after a geriatric lower extremity fracture.

Materials and Methods

We administered a discrete choice experiment survey to 150 patients who were at least 60 years of age and treated for a lower extremity fracture at a Level I trauma center. The discrete choice experiment presented study participants with 8 sets of hypothetical outcome comparisons, including joint preservation (yes or no), risk of reoperation at 6 months and 24 months, postoperative weightbearing status, disposition, and function as measured by return to baseline walking distance. We estimated the relative importance of these potential outcomes using multinomial logit modeling.

Results

The strongest patient preference was for maintained function after treatment (59%, P < .001), followed by reoperation within 6 months (12%, P < .001). Although patients generally favored joint preservation, patients were willing to change their preference in favor of joint replacement if it increased function (walking distance) by 13% (SE, 66%). Reducing the short-term reoperation risk (12%, P < .001) was more important to patients than reducing long-term reoperation risk (4%, P = .33). Disposition and weightbearing status were lesser priorities to patients (9%, P < .001 and 7%, P < .001, respectively).

Discussion

After a lower extremity fracture, geriatric patients prioritized maintained walking function. Avoiding short-term reoperation was more important than avoiding long-term reoperation. Joint preservation through fracture fixation was the preferred treatment of geriatric patients unless arthroplasty or arthrodesis provides a meaningful functional benefit. Hospital disposition and postoperative weightbearing status were less important to patients than the other included outcomes.

Conclusions

Geriatric patients strongly prioritize function over other outcomes after a lower extremity fracture.

Resource Deployment in Response to Trauma Patients

Background Variance in the deployment of the trauma team to the emergency department (ED) can result in patient treatment delays and excess burden on ED personnel. Characteristics of trauma patients, including mechanism of injury, injury type, and age, have been associated with differences in trauma resource deployment. Therefore, this retrospective, single-site study aimed to examine the deployment patterns of trauma resources, the characteristics of the trauma patients associated with levels of trauma resource deployment, and the deployment impact on ED workforce utilization and non-trauma ED patients. Methodology This was an investigator-initiated, single-institution, retrospective cohort study of all patients designated as a trauma response and admitted to a community hospital's ED from July 01, 2019, through July 01, 2022. Results Resource deployment for trauma patients varied by mechanism of injury (p < 0.001), injury type (p < 0.001), and patient age groups (p < 0.001). Specifically, there was a lower average trauma activation for geriatric trauma patients with a fall as a mechanism of injury compared to all younger patient groups with any mechanism of injury (F(5) = 234.49, p < 0.001). In the subsample, there was an average of 3.35 ED registered nurses (RNs) allocated to each trauma patient. Additionally, the ED RNs were temporarily reallocated from an average of 4.09 non-trauma patients to respond to trauma patients, despite over a third of the trauma patients in the subsample being the trauma patients being discharged home from the ED. Conclusions Trauma activation responses need to be standardized with a specific plan for geriatric fall patients to ensure efficient use of trauma and ED personnel resources.

Exposing the Care Conundrum of Low-Energy Pelvic Ring Fractures in Older Adults: A Review of 322 Patients

Introduction

A care conundrum for low-energy pelvic ring fracture patients in which they face financial burden after not qualifying for an inpatient stay of 3 days or more has been noted in the literature. The purpose of this study was to identify factors that lead to inpatient length of stay (IP LOS) ≥3 days in older adults with nonoperative pelvic ring fragility fractures and to highlight the challenging financial decision-making of those with IP LOS <3 days in the context of the Medicare 3-day rule.

Methods

This was a retrospective review of 322 patients aged ≥65 presenting from March 2016 and February 2019 to either of 2 emergency departments (EDs) after a ground-level fall resulting in a pelvic ring fracture. Patient demographic, IP LOS, and mortality data were extracted. Case management notes were analyzed to summarize financial decision-making for patients with IP LOS <3 days. Multivariate logistic regression analysis was conducted to identify factors that predicted IP LOS ≥3 days and mortality.

Results

IP LOS ≥3 days was associated with presentation to level I hospital (OR .30 [.19, 0.50]) and being single (OR 2.50 [1.10, 5.68]). 70.3% required a post-acute skilled nursing facility (SNF) stay. Of patients with LOS <3 days, 25.0% were financially responsible for their SNF stay, while 7.9% elected home care due to financial reasons. Overall 30-day, 90-day, and 1-year mortality were 2.5%, 8.1%, and 20.8%, respectively. For patients with LOS <3 days, returning to assisted living compared to discharging to a SNF increased 90-day mortality risk (HR 8.529, P = .0451). Having Medicare trended towards increased 90-day mortality risk compared to commercial insurance (HR 4.556, P = .0544).

Conclusion

The current system is failing older adult patients who sustain nonoperative low-energy pelvic ring fractures in terms of financial coverage of necessary post-acute treatment. This care conundrum has yet to be solved.

Gluteal Muscle Fatty Atrophy: An Independent Risk Factor for Surgical Treatment in Elderly Patients Diagnosed with Type-III Fragility Fractures of the Pelvis

BACKGROUND

Gluteal muscle fatty atrophy (gMFA) might impair pelvic stability and negatively influence remobilization in patients with fragility fractures of the pelvis (FFP). This study aimed to investigate the association between gMFA and surgical indication in patients with FFP.

METHODS AND MATERIALS

A retrospective analysis of 429 patients (age ≥80) diagnosed with FFP was performed. gMFA of the gluteus maximus, medius, and minimus was evaluated using a standard scoring system based on computer tomography images.

RESULTS

No significant difference was found in gMFA between genders or among FFP types. The severity of gMFA did not correlate with age. The severity of gMFA in the gluteus medius was significantly greater than in the gluteus maximus, whereas the most profound gMFA was found in the gluteus minimus. gMFA was significantly more severe in patients who underwent an operation than in conservatively treated patients with type-III FFP, and an independent correlation to surgical indication was found using logistic regression.

CONCLUSION

Our findings imply that gMFA is an independent factor for surgical treatment in patients with type-III FFP. Besides focusing on the fracture pattern, the further evaluation of gMFA could be a feasible parameter for decision making toward either conservative or surgical treatment of type-III FFP.

Appropriate Imaging for Geriatric Trauma

BACKGROUND

Trauma is the leading cause of preventable death in the United States. Early detection of life-threatening injuries leads to improved survival. Computed tomography (CT) scanning has become the modality of choice for early detection of injuries in the stable patient. Some studies have associated selective imaging (Selective-CT) with equivalent outcomes compared to whole body imaging (Pan-CT) with lower costs and radiation exposure. Within the geriatric population, however, the utility of Pan-CT remains controversial. Therefore, the aim of this study was to determine if a difference exists between Selective-CT and Pan-CT imaging in the geriatric trauma patient.

METHODS

A retrospective analysis of Level 3 (G60) trauma activations presenting to our urban Level I trauma center between June 2016 and June 2019 was performed. Pan-CT was defined by ICD-10 codes indicating a head, cervical spine, chest, abdomen, and pelvis CT series. Patients with missing images and those who were transferred from other institutions were excluded. Logistic regression controlling for age, gender, injury type, severity, and Glasgow Coma Score was performed.

RESULTS

A total of 1014 patients met inclusion criteria. Of these, 30.9% underwent Pan-CT (n = 314), 48.9% had Selective-CT (n = 497), and 20.2% received no CT imaging (n = 203). After logistic regression, no clinically significant variations in emergency department length of stay (LOS), hospital LOS, ICU LOS, ventilator days, discharge disposition, missed injury rate, or mortality rate were observed between imaging strategies.

CONCLUSIONS

Pan-CT provides no clinically significant advantage over Selective-CT in the geriatric trauma patient.

Understanding the Impact of Trauma Admissions to Nonsurgical Services

BACKGROUND

The American College of Surgeons Committee on Trauma (ACS COT) delineates trauma center standards, one of which limits the number of injured patients admitted to nonsurgical services. Performance improvement review of nonsurgical admissions (NSAs), particularly those with Injury Severity Score (ISS) > 9, is required.

OBJECTIVE

To examine trauma patients with NSA for appropriateness of admission and any potential clinical effect as a result of NSA.

METHODS

All trauma patients presenting to our ACS COT-verified level 1 trauma center in Southern California (05/2021-04/2022) were retrospectively screened. Nonsurgical admissions with ISS > 9 were included without exclusions. Appropriateness and clinical impact of NSA were assessed by the Trauma Medical Director (TMD) and Associate TMD.

RESULTS

Forty patients met study criteria, with a mean age of 54 years (range 5 d-99 y). The mean ISS was 19 (range 10-30). Nonsurgical admissions most commonly sustained traumatic brain injury (TBI) (n = 27, 68%) after ground level falls (GLF) (n = 32, 80%). All NSAs were evaluated by ≥1 surgical service, commonly neurosurgery (n = 33, 83%) and trauma surgery (n = 13, 33%). Sixteen patients (40%) died, 75% (n = 12) of which were secondary to catastrophic TBI. Upon detailed review, all NSAs were deemed appropriate and without potential clinical impact.

CONCLUSIONS

All NSAs in this study were appropriate admissions without clinical effect from lack of surgical admission. Nonsurgical admissions were typically elderly patients with head injuries after GLF. With the anticipated increase in geriatric trauma due to our aging population, NSA with surgical consultation may be an important way to manage trauma admissions without compromising care of injured patients.

Effects of Fracture Liaison Service on Outcomes of Patients with Hip Fracture in Rural Area of an Asian Country

Introduction

Fracture Liaison Services (FLS) has been proven effective in reducing subsequent fractures and related mortality. However, more research is needed on the impact of FLS on the 30-day readmission rate and its effectiveness in rural hospitals. This study aims to assess the impact of FLS on clinical outcomes including readmission rates, subsequent fractures, and fracture-related mortality in rural areas of an Asain country.

Materials and methods

In a rural hospital in Taiwan, we conducted a two-year prospective cohort study on elderly individuals with fragility hip fractures. The study compared the clinical outcomes between the control group and the FLS-cohort group. Logistic regression analysis was used to identify factors contributing to 1-year mortality after injury.

Results

556 patients were enrolled. (304 in the control group and 252 in the FLS group) The mean age was 79.8 years. The findings revealed that the introduction of FLS did not result in significant differences in mortality, readmission, complication, subsequent fractures, or secondary hip fractures. However, there were notable improvements in the length of hospital stay and the proportion of patients receiving surgery within 48 h following the implementation of FLS. Subgroup analysis showed that FLS patients who received anti-osteoporotic treatment had lower mortality and 30-day readmission rates. Factors associated with higher 1-year mortality included male, high ASA level, and delayed surgery.

Discussion

This study provides the real-life evidence of the effect of intensive FLS model in a rural hospital in an Asian country.

Conclusion

While FLS did not show significant differences in certain clinical outcomes, it led to shorter hospital stays and increased timely surgeries. FLS patients receiving anti-osteoporotic treatment had better mortality and readmission rates. Further research is necessary to gain a comprehensive understanding of the impact of FLS care in rural areas of Asia.

The effect of restrictive fluid management on outcomes among geriatric hip fractures: a retrospective cohort study at five level I trauma centers

Restrictive fluid management (RFM) for hemodynamically unstable trauma patients has reduced mortality rates. The objective was to determine whether RFM benefits geriatric hip fracture patients, who are usually hemodynamically stable.

Design

Retrospective propensity-matched study.

Setting

Five Level I trauma centers (January 1, 2018-December 12, 2018).

Patients

Geriatric patients (65 years or older) with hip fractures were included in this study. Patients with multiple injuries, nonoperative management, and preoperative blood products were excluded.

Intervention

Patients were grouped by fluid volume (normal saline, lactated Ringer, dextrose, electrolytes, and medications) received preoperatively or ≤24 hours of arrival; patients with standard fluid management (SFM) received ≥150 mL and RFM <150 mL of fluids.

Main Outcome Measurements

The primary outcomes were length of stay (LOS), delayed ambulation (>2 days postoperatively), and mortality. Paired Student t-tests, Wilcoxon paired rank sum tests, and McNemar tests were used; an α value of < 0.05 was considered statistically significant.

Results

There were 523 patients (40% RFM, 60% SFM); after matching, there were 95 patients per arm. The matched patients were well-balanced, including no difference in time from arrival to surgery. RFM and SFM patients received a median of 80 mL and 1250 mL of preoperative fluids, respectively (P < 0.001). Postoperative fluid volumes were 1550 versus 2000 mL, respectively, (P = 0.73), and LOSs were similar between the two groups (5 versus 5 days, P = 0.83). Mortality and complications, including acute kidney injuries, were similar. Delayed ambulation rates were similar overall. When stratified by preinjury ambulation status, SFM was associated with delayed ambulation for patients not walking independently before injury (P = 0.01), but RFM was not (P = 0.09).

Conclusions

RFM seems to be safe in terms of laboratory results, complications, and disposition. SFM may lead to delayed ambulation for patients who are not walking independently before injury.

Increase in Alcohol Use Among the Geriatric Trauma Population During the COVID-19 Pandemic

The COVID-19 pandemic has had profound effects on the everyday behaviors of all patients. At the same time, the United States population is aging, and an increasing portion of traumatically injured patients are geriatric. Our study aims to examine the effects of the COVID-19 pandemic on the geriatric trauma population. We performed a retrospective review of the trauma database from our single institution level I trauma center examining pandemics impact on geriatric trauma demographics, mechanism of injury, injury severity, hospitalization characteristics, and alcohol use. Data during the pandemic was compared to the prior 3 years and controlled for seasonality. Statistical analysis demonstrated an increase in duration of mechanical ventilation and alcohol use during the pandemic while other factors remained stable. This shows the need for targeted alcohol assessment in the geriatric trauma population during periods of social isolation and additional research into the effects of the COVID-19 on trauma patients.

The Rising Problem of Hip Fractures in Geriatric Patients-Analysis of Surgical Influences on the Outcome

BACKGROUND

Hip fractures in geriatric patients often have a poor outcome in terms of mortality, mobility as well as independence. Different surgical influence factors are known that improve the outcome.

METHODS

In this observational cohort study, 281 patients of a geriatric trauma unit were analyzed prospectively. Demographic factors, as well as data regarding the trauma mechanism and perioperative treatment, were recorded. The nutritional status was also analyzed. The follow-up was set to 120 days.

RESULTS

The key conclusion of this study is that a high ASA classification, the use of anticoagulatory medicine and malnutrition are significantly associated with higher mortality together with worse independence (p < 0.05). There is no significant difference in outcome concerning the time to surgery within the first 24 h.

CONCLUSIONS

Malnutrition seems to be an important risk factor for an adverse outcome of geriatric patients and therefore warrants a focus in multidisciplinary treatment. The risk factor ASA cannot be improved during the pre-surgery phase, but requires intensified care by a multidisciplinary team specialized in orthogeriatrics.

Use of a Hindfoot Nail Without Separate Subtalar and Tibiotalar Joint Preparation to Treat Geriatric Ankle and Distal Tibia Fractures: A Case Series

Introduction

Ankle fractures in geriatric patients can be devastating injuries, as they limit an individual's mobility, autonomy, and quality of life. This study examines the functional outcomes and complications related to hindfoot nails (HFN) in geriatric patients who have suffered an ankle malleolar or distal tibia fracture.

Materials and Methods

This is a single-surgeon case-series of patients who underwent HFN for acute fixation or delayed reconstruction after an ankle or distal tibia fracture. Demographic information, comorbidities, baseline functional status, AO/OTA classification, surgical indications, need for external fixation, total operative time, length of stay (LOS), ambulation at discharge, and discharge disposition were recorded. Primary outcomes included 30-day complications, ambulation at follow-up, and time to fracture union and fusion.

Results

There were 22 patients, with average age 80.8 years. Mean LOS was 7.0 days, and 68.2% were discharged to subacute rehabilitation. Within 30 days, 1 patient developed a deep vein thrombosis and bilateral pulmonary emboli, and 2 experienced wound dehiscence requiring antibiotics. At 6-weeks, 1 patient sustained a fall with periprosthetic fracture requiring HFN revision, and another developed cellulitis necessitating hardware removal. Fracture healing was seen in 72.7% at 19.4 weeks, while radiographic fusion occurred in 18.2% at 43.0 weeks. 72.7% were ambulating with an assistive device at discharge, and 100.0% at 12-weeks post-operatively or last follow-up. Upon final examination, all patients were ambulating without pain.

Discussion

HFNs provide a reliable alternative to traditional open reduction internal fixation and have the ability to improve quality of life for geriatric patients through a faster return to weight-bearing. Additionally, radiographic fusion rates show that patients have favorable functional outcomes even without formal arthrodesis.

Conclusion

HFN is beneficial for elderly patients with low functional demand and complex medical comorbidities, as it allows for early mobility after sustaining an ankle or distal tibia fracture.

Inadvertent Perioperative Hypothermia

Temperature regulation during the perioperative period plays an essential role in keeping patients safe while optimizing their recovery. The World Health Organization recommends preserving normothermia, identified as a core body temperature greater than 36°C, to minimize morbidity and mortality. The etiology of inadvertent perioperative hypothermia (IPH) varies in origin. Preoperative exposure, decreased ambient operating room (OR) temperature, skin exposure during preparation, unwarmed skin preparation and washout solutions, and lack of warming devices all contribute to IPH. Moreover, general and regional anesthesia blunt the physiologic response to hypothermia which originates in the hypothalamus. Postoperatively, patients with temperatures < 36°C are at greater risk for surgical site infection, increased mortality, longer length of hospital stay, higher 30-day readmission rates, among other complications. Identifying preoperative risk factors and OR practices that contribute to IPH, monitoring temperatures, and use of warming devices during the perioperative period can help to prevent IPH.

Implementation of a Multidisciplinary Preoperative Protocol for Geriatric Hip Fractures Improves Time to Surgery at a Level III Trauma Center

Introduction

Hip fractures are common among the elderly, and delays in time to surgery (TTS) and length of stay (LOS) are known to increase mortality risk in these patients. Preoperative multidisciplinary protocols for hip fracture management are effective at larger trauma hospitals. The purpose of this study is to evaluate the effect of a similar multidisciplinary preoperative protocol for geriatric hip fracture patients at our Level III trauma center.

Materials and Methods

In this single-center retrospective study, patients aged 65 and older who were admitted from March 2016 to December 2018 (pre-protocol group, Cohort #1, n = 247) and from August 2021 to September 2022 (post-protocol group, Cohort #2, n = 169) were included. Demographic information, TTS, and LOS were obtained and compared using Student's t-test and Chi-square testing.

Results

There was a significant decrease in TTS in Cohort #2 compared to Cohort #1 (P < .001). There was a significant increase in LOS in Cohort #2 compared to Cohort #1 (P < .05), but when comparing a subset of Cohort #2 (Subgroup 2B, patients admitted from May to September 2022 when the effects of COVID-19 were likely dissipated) to Cohort #1, there was no significant difference in LOS (P = .13). For patients admitted to skilled nursing facilities (SNF), LOS in Cohort #2 was significantly longer than in Cohort #1 (P = .001).

Discussion

In general, Level III hospitals have fewer perioperative resources compared to larger Level I hospitals. Despite this fact, this multidisciplinary preoperative protocol effectively reduced TTS which improves mortality risk in elderly patients. LOS is a multifactorial variable, and we believe the COVID-19 pandemic was a significant confounder that reduced available SNF beds in our area which prolonged the average LOS in Cohort #2.

Conclusion

A multidisciplinary preoperative protocol for geriatric hip fracture management can improve efficiency of getting patients to surgery at Level III trauma centers.

Sagittal deformity of Garden type I and II geriatric femoral neck fractures is frequently misclassified by lateral radiographs

The objective of this study was to determine the validity and inter-rater reliability of radiographic assessment of sagittal deformity of femoral neck fractures.

Design

This is a retrospective cohort study.

Setting

Level 1 trauma center.

Patients/Participants

Thirty-one patients 65 years or older who sustained low-energy, Garden type I/II femoral neck fractures imaged with biplanar radiographs and either computed tomography or magnetic resonance imaging were included.

Main Outcome Measurements

Preoperative sagittal tilt was measured on lateral radiographs and compared with the tilt identified on advanced imaging. Fractures were defined as "high-risk" if posterior tilt was ≥20 degrees or anterior tilt was >10 degrees.

Results

Of 31 Garden type I/II femoral neck fractures, advanced imaging identified 10 high-risk fractures including 8 (25.8%) with posterior tilt ≥20 degrees and 2 (6.5%) with anterior tilt >10 degrees. Overall, there was no significant difference between sagittal tilt measured using lateral radiographs and advanced imaging (P = 0.84), and the 3 raters had good agreement between their measurements of sagittal tilt on lateral radiographs (interclass correlation coefficient 0.79, 95% confidence interval [0.65, 0.88], P < 0.01). However, for high-risk fractures, radiographic measurements from lateral radiographs alone resulted in greater variability and underestimation of tilt by 5.2 degrees (95% confidence interval [-18.68, 8.28]) when compared with computed tomography/magnetic resonance imaging. Owing to this underestimation of sagittal tilt, the raters misclassified high-risk fractures as "low-risk" in most cases (averaging 6.3 of 10, 63%, range 6 - 7) when using lateral radiographs while low-risk fractures were rarely misclassified as high-risk (averaging 1.7 of 21, 7.9%, range 1 - 3, P = 0.01).

Conclusions

Lateral radiographs frequently lead surgeons to misclassify high-risk sagittal tilt of low-energy femoral neck fractures as low-risk. Further research is necessary to improve the assessment of sagittal plane deformity for these injuries.

Level of Evidence

Level IV diagnostic study.

Use of Distal Tibial Cortical Bone Thickness and FRAX Score for Further Treatment Planning in Patients with Trimalleolar Ankle Fractures

Trimalleolar ankle fractures show a bimodal age distribution, affecting younger men and older women. Postmenopausal women often exhibit low bone mineral density, which contributes to a higher prevalence of osteoporotic-related fractures. The primary goal of this study was to analyse the association of patient characteristics with the cortical bone thickness of the distal tibia (CBTT) in trimalleolar ankle fractures.

METHODS

A total of 193 patients with a trimalleolar ankle fracture treated between 2011 and 2020 were included. Patient registries were reviewed regarding demographics, mechanism, and type of injury. The CBTT was assessed in radiographs and CT images. The FRAX score was calculated to estimate the probability for an osteoporotic fracture. A multivariable regression model was calculated to identify independent variables affecting the cortical bone thickness of the distal tibia.

RESULTS

Patients older than 55 years were 4.22 (95% CI: 2.12; 8.38) times more likely to be female. In the multivariable regression analysis, female sex (β -0.508, 95% CI: -0.739; -0.278, p < 0.001) and a higher age (β -0.009, 95% CI: -0.149; -0.003, p = 0.002) were independent variables associated with a lower CBTT. Patients with a CBTT < 3.5 mm had a higher 10-year probability for a major osteoporotic fracture (12% vs. 7.75%; p = 0.001).

CONCLUSIONS

The assessment of the peripheral bone quality in routine computed tomography demonstrated that higher age and female sex are significantly associated with reduced cortical bone thickness of the distal tibia. Patients with a lower CBTT showed a higher probability for a subsequent osteoporotic fracture. In female patients with reduced distal tibial bone quality and associated risk factors, an osteoporosis assessment should be evaluated.

Functional Outcomes of Anterior-Based Muscle Sparing Approach Compared to Direct Lateral Approach for Total HIP Arthroplasty Following Acute Femoral Neck Fractures

Introduction

Total hip arthroplasty (THA) performed for femoral neck fractures (FNFs) is becoming a more frequent treatment in the active elderly population. Since there is limited research available presenting clinical outcomes after THA using the anterior-based muscle sparing (ABMS) approach, the aim of this study was to compare this surgical approach to the direct lateral (DL) approach in patients treated by THA for FNFs.

Materials and Methods

We retrospectively reviewed the data prospectively collected as a part of our "Hip Fracture Unit" and included 163 patients who underwent THA from January 2016 to January 2019 for acute displaced FNFs.

Results

A total of 132 patients who completed a minimum 2-years follow up (69 in the ABMS group and 63 in DL group) were included. The ABMS group demonstrated significantly shorter time to reach milestone for hospital discharge (1.5 Days vs 2.1 days, P = .018), while no statistically significant differences were detected in peri-operative complications. At 3 months, the timed up and go test, the Harris Hip Score (HHS) and the Oxford ip Score (OHS) were significantly better (P = .024, .032 and .034, respectively) in the ABMS group compared to the DL group. No differences were found in functional outcomes (HHS and OHS) nor in complication rate at 6, 12 and 24 months.

Discussion

This is one of the first studies to analyze functional results of THA performed for FNFs through an ABMS approach. Results are in line with those already present in the Literature.

Conclusion

ABMS approach allows earlier mobilization and better early functional outcomes, compared to DL approach, in patients undergoing THA for acute displaced FNF. No differences are found after 6 months in functional results and complications rate.

Crosswalk between Charlson Comorbidity Index and the American Society of Anesthesiologists Physical Status Score for Geriatric Trauma Assessment

The American Society of Anesthesiologists Physical Status (ASA-PS) grade better risk stratifies geriatric trauma patients, but it is only reported in patients scheduled for surgery. The Charlson Comorbidity Index (CCI), however, is available for all patients. This study aims to create a crosswalk from the CCI to ASA-PS. Geriatric trauma cases, aged 55 years and older with both ASA-PS and CCI values (N = 4223), were used for the analysis. We assessed the relationship between CCI and ASA-PS, adjusting for age, sex, marital status, and body mass index. We reported the predicted probabilities and the receiver operating characteristics. A CCI of zero was highly predictive of ASA-PS grade 1 or 2, and a CCI of 1 or higher was highly predictive of ASA-PS grade 3 or 4. Additionally, while a CCI of 3 predicted ASA-PS grade 4, a CCI of 4 and higher exhibited greater accuracy in predicting ASA-PS grade 4. We created a formula that may accurately situate a geriatric trauma patient in the appropriate ASA-PS grade after adjusting for age, sex, marital status, and body mass index. In conclusion, ASA-PS grades can be predicted from CCI, and this may aid in generating more predictive trauma models.

Fibula Nail versus Locking Plate Fixation-A Biomechanical Study

In the treatment of ankle fractures, complications such as wound healing problems following open reduction and internal fixation are a major problem. An innovative alternative to this procedure offers a more minimally invasive nail stabilization. The purpose of this biomechanical study was to clarify whether this method was biomechanically comparable to the established method. First, the stability (range of motion, diastasis) and rotational stiffness of the native upper ankle were evaluated in eight pairs of native geriatric specimens. Subsequently, an unstable ankle fracture was created and fixed with a locking plate or a nail in a pairwise manner. The ankles showed significantly less stability and rotational stiffness properties after nail and plate fixations than the corresponding native ankles (p < 0.001 for all parameters). When comparing the two methods, both showed no differences in their range of motion (p = 0.694) and diastasis (p = 0.166). The nail also presented significantly greater rotational stiffness compared to the plate (p = 0.001). However, both fixations remained behind the native stability and rotational stiffness. Due to the comparable biomechanical properties of the nail and plate fixations, an early weight-bearing following nail fixation should be assessed on a case-by-case basis considering the severity of fractures.

Influence of Malnutrition on Outcome after Hip Fractures in Older Patients

Background: Malnutrition might lead to a worse outcome in hip fractures of older patients. The purpose of this study is to analyze different indicators of malnutrition that lead to worse outcomes. Methods: 252 patients of a geriatric trauma unit were analyzed prospectively. Different demographic, as well as data on the trauma and whether osteoporosis prophylaxis or anticoagulation was present, were recorded. The nutritional status with respect to laboratory parameters as well as nutritional risk score was also analyzed. Results: The main finding of this study is that a poor nutritional status is statistically significantly associated with higher mortality as well as worse independence (p < 0.05). A postoperatively prescribed osteoporosis prophylaxis is protective of mortality and independence (p < 0.05). Conclusions: Malnutrition of geriatric patients increases the risk for death, worse mobility, and independence after hip fractures. Osteoporosis prophylaxis prescribed during an inpatient stay enables patients to retain their independence. The nutritional status of geriatric patients with hip fractures should be obtained and provisions made.

Fixation of Proximal Third Humeral Shaft Fractures in Older Patients

Background

Humeral shaft fractures occur frequently in older patients. The more proximal end of the shaft is prone to non-union when compared with more distal fractures. We provide an overview of several key features of this significant patient group.

Method

Our institutional fracture database was searched for all cases of proximal third humeral shaft fractures in patients over 60 years of age. Retrospective evaluation of patient demographics, management, length of stay and incidence of non-union was performed.

Results

75 patients (61 female) were analysed. 33 patients were 'frail' (Clinical Frailty Scores of >4). Non-union occurred in 19 of 45 non-surgically treated fractures and in 1 of 37 cases treated surgically. Mean length of stay was 5.9 days (non-operative) and 6.6 days (operative). Proximal extension into the humeral head is common.

Conclusion

Non-surgical management of proximal third humeral shaft fractures is associated with an increased risk of non-union. We detail an operative technique and case example supporting early fixation of displaced proximal third humeral shaft fractures in older patients that can be utilized for both primary and delayed fixation. In view of the significant association of non-union a well-constructed prospective cohort study with outcome assessment would be of value to further characterize this emerging injury population.Level of Evidence: Level IV, retrospective case series.

Impact of COVID-19 Pandemic on Treatment and Outcome of Fragility Hip Fractures In Non-COVID Patients: Comparison Between the Lockdown Period, a Historical Series and the "Pandemic Normality" in a Single Institution

Introduction

The COVID-19 pandemic has affected and is still deeply affecting all aspects of public life. World governments have been forced to enact restrictive measures to stem the contagion which have led to a decrease in the movement of people within national territory and to a redirection of health care resources with a suspension of non-urgent procedures. In Italy, a lockdown was imposed from March 9^th to May 3^rd, 2020. As a result, a significant reduction in the overall operative volume of orthopedic trauma was expected, but it was not possible to predict a similar trend regarding fragility fractures of the proximal femur in the elderly.

Methods

The aim of this paper was to examine the impact of COVID-19 on the operating volume for trauma surgeries and to determine how the pandemic affected the management of fragility hip fractures (FHFs) in non-COVID patients at a single Institution.

Results

The first result was a statistically significant reduction in the overall operative volume of orthopedic trauma during the period of the first lockdown and an increase in the mean age of patients undergoing surgery, as expected. As regard to the second aim, the incidence of FHFs remained almost unchanged during the periods analysed. The population examined were superimposable in terms of demographics, comorbidities, type of fracture, peri-operative complications, percentage of operations performed within 48 hours from hospitalization and 1-year outcome.

Discussion

Our results are in line with those already present in the Literature.

Conclusions

Our study revealed a significant impact of the restrictive anti-contagion measures on the overall orthopedic surgical volume, but, at the same time, we could affirm that the pandemic did not affect the management of FHFs in non-COVID patients, and their results.

Reoperation Rate of Internal Fixation for Femoral Neck Fractures in the Elderly - A Retrospective Follow-Up Study in 116 Patients With an Exploration of Risk Factors

Aim

Internal fixation of femoral neck fractures is a widely used procedure that is comparatively less invasive and faster than hip replacement. While head preserving internal fixation of these fractures are still preferred where feasible, a faster recovery and lower reoperation rates make arthroplasty increasingly more appealing, in spite of being a more invasive option. Our aim was to determine the reoperation rate after internal fixation at our institution and to explore relevant risk factors in a geriatric population.

Methods

This monocentric follow-up study was conducted analyzing 116 patients aged 65 and older with femoral neck fractures who were surgically treated with either cancellous screws or dynamic hip screws between 2010 and 2017. We retrospectively collected longitudinal data from our patient database, supplemented by a telephone survey, with a follow-up period of at least 18 months.

Results

Twenty reoperations, due to either a failure of fixation, avascular necrosis, or posttraumatic osteoarthritis, were identified in our cohort, which constituted a reoperation rate of 17.2% (20/116). Fracture displacement was significantly associated with the reoperation risk (HR 8, CI 3-20; P < .001). The reoperation rate was 52.2% in displaced fractures vs 8.9% in undisplaced fractures. No link was found between the reoperation rate and gender, age, BMI, ASA score, type of implant, quality of internal fixation, type of living accommodation, and pre-fracture mobility.

Conclusion

Internal fixation has been found to be an effective option in elderly patients with undisplaced fractures regardless of their specific age, cognitive ability or physical condition. In displaced fractures the reoperation rate was found to be high, therefore a primary hip replacement should be recommended.

Sources of Postacute Care Episode Payment Variation After Traumatic Hip Fracture Repair Among Medicare Beneficiaries: Cross-Sectional Retrospective Study

The objective of this study was to evaluate how much variation in postacute care (PAC) spending after traumatic hip fracture exists between hospitals, and to what degree this variation is explained by patient factors, hospital factors, PAC setting, and PAC intensity.

Background

Traumatic hip fracture is a common and costly event. This is particularly relevant given our aging population and that a substantial proportion of these patients are discharged to PAC settings.

Methods

It is a cross-sectional retrospective study. In a retrospective review using Medicare claims data between 2014 and 2019, we identified PAC payments within 90 days of hospitalization discharges and grouped hospitals into quintiles of PAC spending. The degree of variation present in PAC spending across hospital quintiles was evaluated after accounting for patient case-mix factors and hospital characteristics using multivariable regression models, adjusting for PAC setting choice by fixing the proportion of PAC discharge disposition across hospital quintiles, and adjusting for PAC intensity by fixing the amount of PAC spending across hospital quintiles. The study pool included 125,745 Medicare beneficiaries who underwent operative management for traumatic hip fracture in 2078 hospitals. The primary outcome was PAC spending within 90 days of discharge following hospitalization for traumatic hip fracture.

Results

Mean PAC spending varied widely between top versus bottom spending hospital quintiles ($31,831 vs $17,681). After price standardization, the difference between top versus bottom spending hospital quintiles was $8,964. Variation between hospitals decreased substantially after adjustment for PAC setting ($25,392 vs $21,274) or for PAC intensity ($25,082 vs $21,292) with little variation explained by patient or hospital factors.

Conclusions

There was significant variation in PAC payments after a traumatic hip fracture between the highest- and lowest-spending hospital quintiles. Most of this variation was explained by choice of PAC discharge setting and intensity of PAC spending, not patient or hospital characteristics. These findings suggest potential systems-level inefficiencies that can be targeted for intervention to improve the appropriateness and value of healthcare spending.

Early Surgical Care of Anticoagulated Hip Fracture Patients Is Feasible-A Retrospective Chart Review of Hip Fracture Patients Treated with Hip Arthroplasty within 24 Hours

Anticoagulative medication such as antiplatelet drugs (PAI, acetylsalicylic acid and direct platelet aggregation inhibitors), vitamin-K-antagonist Warfarin (VKA) or direct oral anticoagulants (DOAC) are common among hip fracture patients, and the perioperative management of these patients is a rising challenge in orthopaedic trauma. Our objective was to determine the effect of oral anticoagulation in patients receiving early endoprosthetic treatment within 24 h after their admission. For the period from 2016 to 2020, a retrospective chart review of 221 patients (mean age 83 ± 7 years; 161 women and 60 men) who were treated either with hemi- (n = 209) or total hip arthroplasty (n = 12) within 24 h after their admission was performed. We identified 68 patients who took PAI, 34 who took DOAC and 9 who took VKA medications. The primary outcome measures were the transfusion rate and the pre- and postoperative haemoglobin (Hb) difference. The secondary outcome measures were the in-patient mortality and the rate of postoperative haematomas that needed operative treatment. A logistic/ordinal regression was performed considering the related variables to prevent cofounding occurring. The mean time to surgery was significantly longer for the DOAC and VKA groups when they were compared to the controls (none 14.7 ± 7.0 h; PAI 12.9 ± 6.7 h; DOAC 18.6 ± 6.3 h; VKA 19.4 ± 5.5 h; p < 0.05). There was no difference in the preoperative Hb level between the groups. Overall, 62 patients (28%) needed blood transfusions during the in-patient stay with an ASA classification (p = 0.022), but the type of anticoagulative medication was not a significant predictor in the logistic regression. Anticoagulation with DOAC and grouped surgery times were positive predictors for a higher Hb difference in the patients who did not undergo an intraoperative blood transfusion (n = 159). Postoperative haematomas only occurred in patients taking anticoagulative medication (four cases in PAI group, and three cases in DOAC group), but the logistic regression showed that the anticoagulative medication had no effect. The in-patient mortality was significantly influenced by a high ASA grade (p = 0.008), but not by the type of anticoagulative medication in patients who were treated within 24 h. We conclude that the early endoprosthetic treatment of the anticoagulated hip fracture patient is safe, and a delayed surgical treatment is no longer justifiable.

Outcomes After Revision Fixation With Cement Augmentation for Failed Intertrochanteric Fracture Fixation in Older Adult Patients

Introduction

Intertrochanteric (IT) fractures that fail fixation are traditionally treated with arthroplasty, introducing significant risk of morbidity and mortality in frail older adult patients. Revision fixation with cement augmentation is a relatively novel technique that has been reported in several small scale international studies. Here we report a clinical series of 22 patients that underwent revision fixation with cement augmentation for IT fracture fixation failure.

Methods

This retrospective case series identified all patients that underwent revision intramedullary nailing from 2018 to 2021 at two institutions within a large metropolitan healthcare system. Demographics, injury characteristics, Charlson Comorbidity Index score, and surgical characteristics were extracted from the electronic medical record. Outcomes were extracted from the electronic medical record and included radiographic findings, pain, functional outcomes, complications, and mortality.

Results

Average follow-up after revision surgery was 15.2 ± 10.6 months. Twenty patients (90.9%) reported improved pain and achieved union or progressive healing after surgery. Most of these patients regained some degree of independent ambulation (19 patients, 86.4%), with only 5 patients (22.7%) requiring increased assistance for their activities of daily living (ADLs). One-year mortality was 13.6% (3 patients). Of the 5 patients (22.7%) that experienced complications, 2 patients (9.1%) required revision hemiarthroplasty for subsequent fixation failure. The other 3 patients did well when complications resolved.

Conclusions

Revision fixation with cement augmentation can be an effective, safe, cost-effective alternative to arthroplasty for the management of cases involving non-infected failed IT fracture fixation with implant cut-out or cut-through limited to the femoral head in older adult patients that have appropriate acetabular bone stock.

Hip Fracture Care in Parkinson Disease: A Retrospective Analysis of 1,239 Patients

Introduction

Compared to other patients, Parkinson disease (PD) patients may experience suboptimal outcomes after hip fracture. The purpose of this study was to describe and compare characteristics and outcomes of hip fracture patients with PD to those without PD.

Methods

This retrospective cohort study included all patients admitted for hip fracture within a large healthcare system between July 1, 2017 and June 30, 2019. Demographics, injury characteristics, Charlson Comorbidity Index (CCI), treatment characteristics, and outcomes including complications, readmissions, and mortality were extracted. Patients with PD were compared to those without PD. Chi-square tests, two-sample t-tests, and Fisher exact tests were conducted to identify group differences.

Results

A total of 1239 patients were included (4.0% PD and 96.0% non-PD). PD patients were mostly male (59.2%) compared to mostly female non-PD patients 69.4%, P < .001). PD patients on average had a higher CCI (2.3 vs 1.7, P = .040) and more frequently had dementia (42.9% vs 26.7%, P = .013). No PD patients were discharged home without additional assistance compared to 8.1% of patients without PD. More PD patients were discharged to a skilled nursing facility (SNF) than non-PD patients (65.3% vs 48.2%, P = .021). Only 22.4% of PD patients were previously prescribed osteoporosis medication, and only 16.3% were referred for osteoporosis follow-up after fracture. In-house complications, readmissions, and mortality up to 1 year were comparable between groups (P>.191).

Conclusions

Outcomes between PD patients and non-PD patients were mostly equivalent, but more PD patients required discharge to a higher-level care environment compared to non-PD patients. Although PD seems to be a risk factor for hip fracture regardless of age and sex, most patients had not undergone proper screening or preventative treatment for osteoporosis. These results emphasize the need for early bone health evaluation, multidisciplinary collaboration, and care coordination in preventing and treating hip fractures in PD.

Management of Femoral Neck Fracture in Above Knee Amputee with Femoral Neck System: A Case Report

Introduction

Femoral neck fractures in patients with a history of above knee amputation present as a strain for orthopedic surgeons due to the difficulty of positioning and handling of the limb for proper reduction. Surgical treatment options typically involve open reduction internal fixation versus arthroplasty depending on patient factors such as age, surgeon skill, and available equipment.

Case Report

We present a case of a femoral neck fracture (OTA 31-B2) in a relatively active 89-year-old Caucasian male after a ground level fall that has been ambulating with a prosthesis since his teenage years. In this report, we describe the patient positioning, technique used to treat a femoral neck fracture (OTA 31-B2) using the femoral neck system, and the successful outcome of our patient 1 year from the injury.

Conclusion

We conclude that using the femoral neck system (FNS) is a viable option for patients with a high above knee amputation where, due to the length of the limb and potentially the lack of appropriately sized implants, dislocating and reducing the hip for total hip arthroplasties and hemiarthroplasties provide a challenge.

The Impact of the Fascia Iliaca Block Beyond Perioperative Pain Control in Hip Fractures: A Retrospective Review

Background

Geriatric hip fractures are common injuries that are associated with high morbidity and mortality. Adequate pain control remains a challenge as the altered physiology in elderly patients makes use of traditional analgesics challenging. The use of regional anesthetics, specifically the fascia iliaca compartment block (FICB), in the perioperative period has been shown to decrease opioid use in this population. This study aimed to investigate the effect the FICB had on pain control, length of stay, readmissions, and complications in a 30-day postoperative period.

Methods

This was a retrospective cohort study comparing patients who sustained hip fractures; one cohort (110 patients) received a preoperative fascia iliaca block with continuous infusion (FICB), whereas the other cohort (110 patients) did not receive a block (NO-FICB). Both cohorts were from level II trauma centers. Data were collected between 2016 and 2019. Descriptive statistics was performed to describe and summarize the data. Bivariate analysis was performed using chi-square test, with 2 tailed P-values ≤ .05 were considered statistically significant.

Results

The FICB group had a lower length of stay (3.9 days vs 4.8 days; P < .001), and lower pain scores on post-operative days 2 and 3 (P = .019). There was no difference in time from admission to surgery (P = .112) or narcotic use between cohorts (P = .304). However, the FICB group was more likely to discharge to a skilled nursing facility (P=.002), and more likely to be readmitted within 30 days (P = .047). There were no differences in medical complications or mortality between the 2 groups.

Conclusions

The primary study endpoint, length of stay, was found to be significantly shorter in the patients who underwent the FICB vs the group who did not undergo the FICB. Pain scores on POD2 and POD3 were lower in patients who received a FICB. This study adds to the body of evidence that the FICB is an effective addition to a multimodal pain pathway.

Health Economic Challenge: Geriatric Trauma-An Age-Based Observational Analysis of Treatment Costs and Reimbursement Issues

Demographic change is having a major impact on the economic and structural development of the healthcare system. People stay active longer and the number of mild traumatic brain injury [mTBI] in patients ≥ 65 years of age consequently increases. The aim of this comparative analysis is to illustrate the impact of demographic change and the increasing treatment of geriatric trauma patients on the cost structure of the health care system using mTBI as an example diagnosis. Patients and Methods: The 12-month retrospective analysis included 220 in-patients treated with mTBI and remunerated under the German Diagnosis Related Group [G-DRG] B80Z. For comparative analysis, the patient population was divided into two study groups according to age [U65 18−64 years, G65 ≥ 65 years]. For the cost and proceeds calculation, itemized cost reports (personnel, supply, material, and equipment costs, etc.) were created. Results: 163 patients U65 and 57 patients G65 were included. In the G65 group, the most frequent accident mechanism was a fall from a short distance (84.1 vs. U65 36.7%; p = 0.007). For the inpatient admission of G65, the use of anticoagulants (p < 0.001) and comorbidity (p = 0.002) played a primary role, while for younger patients it was more neurological symptoms (p < 0.001) and alcohol (p < 0.001) that led to inpatient monitoring. The mean length of hospitalization of G65 patients was significantly longer than that of younger patients (G65 2.4 ± 1.9 days > U65 1.7 ± 0.8 days; p = 0.007) and radiological examinations (G65 94.7% > U65 23.3%; p = 0.013) were performed more frequently. Comparing analysis of the cost and proceeds of U65 vs. G65 results in a proceeds difference of €51,753.91 per year for the G-DRG B80Z compared to U65. Conclusions: It has been shown that there is a difference in costs and proceeds when comparing younger and older patients, resulting in a reimbursement deficit. In view of the demographic development in Europe, flat-rate remuneration will lead to a considerable discrepancy between DRG reimbursement and the coverage of hospitals’ running costs. Providing health care to an increasingly aging society represents one of the major personnel and financial challenges for the public health system in the coming decades. Further adaptation of the DRG system to the growing costs caused by older patients is imperative.

Pre-Operative Medications as a Predictor for Post-Operative Complications Following Geriatric Hip Fracture Surgery

Background

Fragility hip fractures are a common orthopedic injury seen in Emergency Departments, with variable outcomes that can range from average to devastating. Currently, few reliable metrics to predict which patients will suffer post-operative complications exist. The aim of this study was to determine if the number and type of pre-operative medications can help predict post-operative complications.

Methods

A prospectively collected database of hip fracture patients was retrospectively reviewed. Patients with isolated greater trochanteric fractures, periprosthetic fractures, or re-fractures were excluded. Pre-operative baseline characteristics as well as number and type of post-operative complications were reviewed. Any complication within 6 months of surgery and complications that could be directly attributable to the surgical procedure within 2 years of surgery were examined. Major complications (return to the operating room, deep infection, pulmonary, cardiac, and hematologic) and minor medical complications were assessed. A multivariate regression model was performed to identify independent risk factors.

Results

Three-hundred ninety-one patients were included. A majority were aged 80–90 and female, and lived at home prior to presentation. Overall, 33.7% of patients suffered a complication within a 2-year follow-up period. Mortality rates were 5.4%, 10.0%, and 14.9% over 30 days, 1 year, and 2 years, respectively. After assessing this relationship while controlling for age, sex, injury type, pre-operative residence, ambulatory status, ASA score, and CCI score, the relationship remained significant for both an increased number of complications (P = .048) and a higher likelihood of having a complication (P = .008). Cardiovascular (P = .003), pulmonary (P = .001), gout (P = .002), or diabetes (P = .042) medications were associated with a higher likelihood for experiencing a complication.

Conclusions

Our study suggests that there is a strong and linear relationship between the number and type of pre-operative medications taken and risk of post-operative complications. This exists for up to 8 medications, at which point further increase does not contribute to an increased risk of complication. This relationship exists even after controlling for confounding variables and can be used by surgeons to better counsel patients and families regarding their specific risk for suffering perioperative complications.

Timing of Surgery for Hip Fracture in Patients on Direct Oral Anti-coagulants: A Population-Based Cohort Study

Background

In patients with hip fracture on direct oral anti-coagulants (DOACs), timely surgery is important in optimising outcomes but the safety of early surgery is unclear. This study aims to evaluate the timing of surgery on peri- and post-operative outcomes in patients with hip fracture on DOAC therapy.

Methods

Single-centre, retrospective, population-based cohort study of patients on DOAC therapy compared to standard care with low-molecular-weight heparin (LMWH) undergoing surgery for hip fracture. Data obtained: patient demographics, fracture classification, American Society of Anaesthesiologists (ASA) classification, time to surgery, procedure performed, type of DOAC, timing of last DOAC dose, use of reversal agents or pro-coagulants and length of stay. Outcomes assessed: pre- and post-operative haemoglobin levels, incidence of blood transfusion, major haemorrhage, venous thromboembolism (VTE) and death within 30 days of surgery.

Results

A total of 755 patients were included. Compared to standard treatment, DOAC use was associated with a similar change in pre- and post-operative haemoglobin levels (P = .90), risk of blood transfusion (RR: 1.04, 95% CI: .70–1.54, P = .84), haemorrhage (RR: 1.51, 95% CI: .53-4.28, P = .44), VTE (RR: .92, 95% CI: .12–7.20, P = .94) and mortality (RR: 1.85, 95% CI: .89–3.84, P = .10), all of which were independent of the timing of surgery.

Conclusion

This study builds on growing evidence that surgery for hip fracture in patients on DOAC therapy is not associated with an excessive risk of haemorrhage, irrespective of the timing of surgery. Timely surgical fixation of the hip fracture in this population is indicated in the absence of other risk factors for haemorrhage.

Evaluation of the Nelson Criteria as an Indicator for Nonsurgical Admission in Trauma Patients

Geriatric patients with complex medical comorbidities who sustain minor injuries may warrant admission to nonsurgical services. The Nelson score provides an objective scoring system that helps identify patients appropriate for nonsurgical admission (NSA). The purpose of this study is to assess the utility of the Nelson criteria in determining the most appropriate admission service. A retrospective review was performed on patients ≥65 years admitted from 12/2016 to 11/2020. 2410 patients met the inclusion criteria. Patients with Nelson score ≥6 were older with more comorbidities, had a lower injury severity score (7.5 vs 12.5, p<0.0001), and a higher rate of NSA (29.2% vs 12.7%, p<0.0001) compared to patients with Nelson score <6. On the multivariable logistic regression, admission service was not identified as an independent predictor of mortality. Utilizing the Nelson criteria may provide an objective measure to stratify and identify patients who would benefit from NSA.

Frailty Is Associated With Worse Outcomes In Geriatric Pelvic Fractures

Frail, geriatric patients with pelvic fractures can present differently than non-frail patients. Using the Clinical Frailty Scale(CFS), a retrospective analysis was conducted to determine the relationship between patients' CFS and outcomes after pelvic fractures. We hypothesized that frail, geriatric trauma patients defined as a CFS>4 with pelvic fractures have worse outcomes than non-frail patients with a CFS≤4 despite similar injuries. All geriatric patients with pelvic fractures and documented CFS were included. Seventy patients were included, with 59% (n = 41) frail. The groups were compared with no difference in mortality. The frail group was older and were most likely discharged to a skilled nursing facility (65.8%). Non-frail were most likely discharged to acute rehab (52%). Frail had lower functional status at discharge (median: 14.5v.16, P = .015). Frail patients had worse overall outcomes in this analysis of geriatric pelvic fracture patients. Special attention should focus on this vulnerable population to ensure optimal treatment and outcomes.

Geriatric Trauma Patients: Outcomes Before and After Addition of a Hospitalist Consultation

BACKGROUND

Research has shown improvements in patient care and outcomes with addition of a rounding geriatrician. The purpose of this study was to determine if addition of a hospitalist consultation improved patient outcomes.

METHODS

A retrospective review was conducted of all trauma patients, ≥65 years, before (n=481) and after (n=430) addition of a hospitalist consultant. Data included were demographics, comorbidities, injury severity, blood pressure, laboratory levels, pain control methods, ICU and ventilator requirements, complications, hospital length of stay, mortality, preexisting wishes, and 30-day readmission.

RESULTS

Adding a hospitalist consultation did not improve blood glucose or blood pressure control. It decreased narcotics-only use (36.0% vs 73.8%) while increasing multimodal pain control use (51.8% vs 14.8%, P<.001) and testing of HbA1c (7% vs .6%, P<.001). There was also increased knowledge of patient resuscitation status preferences (29.1% vs 12.9%, P<.001).

CONCLUSIONS

This article does not support use of routine hospitalist consultation in the geriatric trauma population. However, with study limitations, we continue to evaluate hospitalist utility and will adjust our daily rounds to more closely match prior studies.

Review of Postoperative Delirium in Geriatric Patients After Hip Fracture Treatment

Introduction

Postoperative delirium (POD) is a serious complication occurring in 4–53.3% of geriatric patients undergoing surgeries for hip fracture. Incidence of hip fractures is projected to grow 11.9% from 258,000 in 2010 to 289,000 in 2030 based on 1990 to 2010 data. As prevalence of hip fractures is projected to increase, POD is also anticipated to increase.

Signficance

Postoperative delirium remains the most common complication of emergency hip fracture surgery leading to high morbidity and mortality rates despite significant research conducted regarding this topic. This study reviews literature from 1990 to 2021 regarding POD in geriatric hip fracture management.

Results

Potentially modifiable and non-modifiable risk factors for developing POD include, but are not limited to, male gender, older age, multiple comorbidities, specific comorbidities (dementia, cognitive impairment, diabetes, vision impairment, and abnormal blood pressure), low BMI, preoperative malnutrition, low albumin, low hematocrit, blunted preoperative cytokines, emergency surgery, time to admission and surgery, preoperative medical treatment, polypharmacy, delirium-inducing medications, fever, anesthesia time, and sedation depth and type. Although the pathophysiology remains unclear, the leading theories suggest neurotransmitter imbalance, inflammation, and electrolyte or metabolic derangements as the underlying cause of POD. POD is associated with increased length of hospital stay, cost, morbidity, and mortality. Prevention and early recognition are key factors in managing POD. Methods to reduce POD include utilizing interdisciplinary teams, educational programs for healthcare professionals, reducing narcotic use, avoiding delirium-inducing medications, and multimodal pain control.

Conclusion

While POD is a known complication after hip fracture surgery, further exploration in prevention is needed. Early identification of risk factors is imperative to prevent POD in geriatric patients. Early prevention will enhance delivery of health care both pre- and post-operatively leading to the best possible surgical outcome and better quality of life after hip fracture treatment.

A "GAP" in Activation: A Better Way to Manage Geriatric and Anticoagulated Patients with Head Trauma

BACKGROUND

Older age and anticoagulant use have been associated with worse outcomes in trauma. At the study institution, elderly and anticoagulated patients with suspected traumatic brain injury (TBI) were previously triaged as a second tier trauma team activation (TTA) with a high rate of over-triage. A novel "GAP" (Geriatric or Anticoagulated Pathway) alert was created to streamline care delivery to these patients. The purpose of the study is to assess the efficacy and outcomes of the GAP alert.

METHODS

A retrospective review was conducted on adult patients presenting to a level-1 trauma center from 1/2018-12/2020. The GAP alert was implemented in 2/2018. The GAP alert group was compared to the second tier TTA group.

RESULTS

1743 patients were identified. 504 (29%) received a GAP alert. GAP alert patients were older (79 years vs 47 years, P < .0001), had a lower injury severity score (ISS) (8.6 vs 9.9, P = .006), and had a higher rate of pre-injury anticoagulant use (28.4% vs 2.5%, P < .0001). The in-hospital mortality was higher in the GAP group (2.4% vs .7%, P = .004). On multivariable logistic regression, GAP alert was not identified as a predictor of mortality. Age, ISS, and pre-injury anticoagulant use predicted mortality. During the study period, the number of GAP alerts increased (B = .15, P = .003) and the number of second tier TTAs decreased (B = -.33, P < .0001).

CONCLUSION

Implementation of the GAP alert led to a decrease in trauma resource utilization while providing timely diagnosis and treatment of geriatric patients or those on anticoagulation medication with suspected TBI.

Immediate Full Weight-Bearing Versus Partial Weight-Bearing After Plate Fixation of Distal Femur Fractures in Elderly Patients. A Randomized Controlled Trial

Introduction

After surgery for distal femur fractures in elderly patients, weight-bearing is commonly restricted. Immediate non-restrictive weight-bearing might have beneficial effects. There are no randomized studies on the topic. The purpose of this study was to compare the functional outcome between immediate full weight-bearing (FWB) as tolerated and partial weight-bearing (PWB) during the first 8 weeks following plate fixation of distal femur fractures in elderly patients.

Methods

Patients aged 65 years or older with distal femur fractures of AO/OTA types 33 A2, A3, B1, B2, C1, and C2 were included. Exclusion criteria were impaired cognitive function, concomitant injuries, or inability to follow the postoperative regimen. Internal fixation was achieved with an anatomical lateral distal femur plate applied as a strictly bridge-plating construct. The primary outcome measure was the function index of the short musculoskeletal functional assessment (SMFA) after 52 weeks from injury.

Results

Thirty-two patients were randomized to FWB (n = 11) or PWB (n = 21). After 16 and 52 weeks, there were no differences in the mean SMFA function index between FWB and PWB (36 vs 43, P = .42 and 52 vs 40, P = .18, respectively) nor in the mean EuroQol 5-dimension index or range of motion (ROM). Overall, the SMFA function index was higher at 52 weeks compared with before injury (44 vs 30, P = .001) as was the mean bothersome index (37 vs 21, P = .011). There was no clear difference in the occurrence of adverse events between the treatment groups.

Conclusions

There were no differences in functional outcome, adverse events, or ROM between immediate FWB and PWB following plate fixation for a distal femur fracture in elderly patients. A distal femur fracture has a negative effect on the functional status of elderly patients that persists at least up to 1 year following injury.

Identification of Seniors at Risk Scoring in Geriatric Trauma: Exploring Clinical Outcome Correlations

Introduction

Geriatric trauma patients (GTP) make up an increasing percentage of the overall trauma population. Due to frailty, GTP are at an increased risk of morbidity and readmission. Therefore, it is becoming increasingly important to prognosticate outcomes to assist with resource utilization. We hypothesized that the "Identification of Seniors at Risk" (ISAR) score may correlate with both clinical outcomes and resource utilization for geriatric trauma patients.

Methods

Patients older than 65 years who were admitted to the trauma service were screened using an ISAR scoring algorithm. Outcomes, including 30-day mortality, all-cause morbidity, hospital length of stay (LOS), intensive care unit (ICU) LOS, functional independence measures (FIM) at discharge, and percent discharged to a facility, were analyzed. Both descriptive and data-appropriate parametric and non-parametric statistical approaches were utilized, with significance set at α = 0.05.

Results

One thousand and two hundred seventeen GTP were included in this study. The average age was 81, median injury severity score was 9, and 99% had a blunt trauma mechanism. ISAR scores were generally associated with increasing 30-day mortality (0%, 1.9%, 2.4%, and 2.1% for ISAR 0, ISAR 1-2, ISAR 3-4, and ISAR 5-6, respectively), morbidity (2.6%, 7.6%, 14.7%, and 7.3% for respective categories), longer hospital (3.1, 4.6, 5.1, and 4.3 days, respectively) and ICU stays (0.37, 0.64, 0.81, and 0.67, respectively), lower FIM score at discharge (18.5, 17.1, 15.8, and 14.4, for respective categories), as well as increasing percentage of patients discharged to a facility (29.8%, 58.9%, 72.1%, and 78.8% for respective categories).

Conclusions

This exploratory study provides important early insight into potential relationships between ISAR and geriatric trauma outcomes. ISAR screening is a quick and easy-to-use tool that may be useful in GTP triage, level-of-care determination, and disposition planning. Understanding populations at risk, especially those with more intricate discharge needs, is an important step in mitigating those risks and implementing appropriate care plans.

Geriatric Proximal Femur Fractures During the Covid-19 Pandemic - Fewer Cases, But More Comorbidities

Background:

The COVID-19 pandemic is challenging healthcare systems worldwide. This study examines geriatric patients with proximal femur fractures during the COVID-19 pandemic, shifts in secondary disease profile, the impact of the pandemic on hospitalization and further treatment.

Methods:

In a retrospective monocentric study, geriatric proximal femur fractures treated in the first six months of 2020 were analyzed and compared with the same period of 2019. Pre-traumatic status (living in a care home, under supervision of a legal guardian), type of trauma, accident mechanism, geriatric risk factors, associated comorbidities, time between hospitalization and surgery, inpatient time and post-operative further treatment of 2 groups of patients, aged 65-80 years (Group 1) and 80+ years (Group 2) were investigated.

Results:

The total number of patients decreased (70 in 2019 vs. 58 in 2020), mostly in Group 1 (25 vs. 16) while the numbers in Group 2 remained almost constant (45 vs. 42). The percentage of patients with pre-existing neurological conditions rose in 2020. This corresponded to an increase in patients under legal supervision (29.3%) and receiving pre-traumatic care in a nursing home (14.7%). Fractures were mostly caused by minor trauma in a home environment. In 2020, total number of inpatient days for Group 2 was lower compared to Group 1 (p = 0.008). Further care differed between the years: fewer Group 1 patients were discharged to geriatric therapy (69.6% vs. 25.0%), whereas in Group 2 the number of patients discharged to a nursing home increased.

Conclusions:

Falling by elderly patients is correlated to geriatric comorbidities, consequently there was no change in the case numbers in this age group. Strategic measures to avoid COVID-19 infection in hospital setting could include reducing the length of hospital stays by transferring elderly patients to a nursing home as soon as possible and discharging independent, mobile patients to return home.

Combined Surgical and Medical Treatment for Vancouver B1 and C Periprosthetic Femoral Fractures: A Proposal of a Therapeutic Algorithm While Retaining the Original Stable Stem

INTRODUCTION

There is lack of consensus regarding best operative fixation strategy for periprosthetic femoral fractures (PFFs) around a stable stem. Evidence exists that some patterns of fracture around a stable stem are better treated with revision surgery than with standard fixation. Anyway, a more aggressive surgical procedure together with medical treatment could allow for stem retention, and reduced risk of nonunion/hardware failure, even in these cases.

SIGNIFICANCE

This paper is placed in a broader context of lack of studies on the matter, and its aim is to shed some light on the management of PFFs around a stable stem, when peculiar mechanical and biological aspects are present.

RESULTS

Based on our casuistry in the treatment of nonunions after PFF successfully treated with original stem retention, and on review of Literature about risk factors for fixation failure, an algorithm is proposed that can guide in choosing the ideal surgical technique even for first-time PFFs with a stable stem, without resorting to revision. Mechanical (major and minor) and biological (local and systemic) factors that may influence fracture healing, leading to nonunion and hardware failure, and subsequent need for re-operation, are considered. The proposed surgical technique consists of rigid fixation with absolute stability (using a plate and structural allograft) plus local biological support (structural allograft and autologous bone marrow concentrate over a platelet-rich plasma-based scaffold) at fracture site. Systemic anabolic treatment (Teriparatide) is also administered in the post-operative period.

CONCLUSION

Mechanical factors are not the only issues to be considered when choosing the surgical approach to PFFs over a stable stem. Systemic and local biological conditions should be taken into account, as well. A therapeutic algorithm is proposed, given the prosthetic stem to be stable, considering mechanical and biological criteria.

Prediction of Postoperative Delirium in Geriatric Hip Fracture Patients: A Clinical Prediction Model Using Machine Learning Algorithms

Introduction

Postoperative delirium in geriatric hip fracture patients adversely affects clinical and functional outcomes and increases costs. A preoperative prediction tool to identify high-risk patients may facilitate optimal use of preventive interventions. The purpose of this study was to develop a clinical prediction model using machine learning algorithms for preoperative prediction of postoperative delirium in geriatric hip fracture patients.

Materials & Methods

Geriatric patients undergoing operative hip fracture fixation were queried in the American College of Surgeons National Surgical Quality Improvement Program database (ACS NSQIP) from 2016 through 2019. A total of 28 207 patients were included, of which 8030 (28.5%) developed a postoperative delirium. First, the dataset was randomly split 80:20 into a training and testing subset. Then, a random forest (RF) algorithm was used to identify the variables predictive for a postoperative delirium. The machine learning-model was developed on the training set and the performance was assessed in the testing set. Performance was assessed by discrimination (c-statistic), calibration (slope and intercept), overall performance (Brier-score), and decision curve analysis.

Results

The included variables identified using RF algorithms were (1) age, (2) ASA class, (3) functional status, (4) preoperative dementia, (5) preoperative delirium, and (6) preoperative need for mobility-aid. The clinical prediction model reached good discrimination (c-statistic = .79), almost perfect calibration (intercept = −.01, slope = 1.02), and excellent overall model performance (Brier score = .15). The clinical prediction model was deployed as an open-access web-application: https://sorg-apps.shinyapps.io/hipfxdelirium/.

Discussion & Conclusions

We developed a clinical prediction model that shows promise in estimating the risk of postoperative delirium in geriatric hip fracture patients. The clinical prediction model can play a beneficial role in decision-making for preventative measures for patients at risk of developing a delirium. If found to be externally valid, clinicians might use the available web-based application to help incorporate the model into clinical practice to aid decision-making and optimize preoperative prevention efforts.

The Abbreviated Mental Test Score; Is There a Need for a Contemporaneous Update?

Introduction

Designed in 1972 the Abbreviated Mental Test Score (AMTS) is widely used to assess a cognition on hospital admission. The Nottingham Hip Fracture Score uses this in predicting morbidity/mortality in neck of femur fracture. The consequences of misappropriating cognitive impairment could have lasting implications. Questions about the monarchy or World War One and Two may be inappropriate for today's diverse society.

Materials and Methods

100 patients were questioned during routine fracture clinic appointments. Patients were asked: In what year did WWII start? Who is the current monarch? Please state a memorable event in your lifetime that you would not expect another person of the same age to forget. Two-tailed Z-tests were performed between the observed proportions and those from the original AMTS validation study.

Results

Only 47% (n = 47) were able to correctly answer the year in which WW2 started. A statistically significant difference when compared to the upper and lower limits from the original study (z = -4.191, p < .001.). Significance was not seen in the second question, with 97% (n-97) identifying the monarch correctly. 51% (n = 51) of participants suggested the terrorist attack on the World Trade Centre in New York as an alternative memorable event.

Discussion

Some hospitals now use the 4 "A"s Test (4-AT) as a screening tool for delirium. Without amendments to the Nottingham Hip Fracture Score, AMTS use is likely to continue in orthogeriatric patients. Over time there will be a need for the AMTS to be reviewed so that it remains a true assessment of cognition. Its limitations regarding language and culture is widely acknowledged and several validated variants have been published in the literaure.

Conclusions

We highlight a potential future issue with the AMTS and raise considerations for the development of an alternative question to better meet the needs of the orthogeriatric population.

Finite Element Analysis of Cannulated Screws as Prophylactic Intervention of Hip Fractures

Introduction

The frequency of hip fractures, a major cause of morbidity and mortality for geriatric patients, is expected to increase exponentially in the next few decades. The aim of this study is to assess the ability of stainless-steel cannulated screws to reduce the risk of a femoral neck fracture, if placed prophylactically prior to a fall.

Materials and Methods

We created finite element models from computed tomography (CT) scan-based 3D models of a geriatric patient through 3D-image processing and model generation software. We used linear finite element simulations to analyze the effect of cannulated screws in the proximal femur in single-leg stance and lateral fall, which were processed for peak von Mises stresses and element failure.

Findings

Prophylactically placed cannulated screws significantly reduced failure in an osteoporotic proximal femur undergoing lateral fall. Three implanted screws in an inverted triangle formation decreased proximal femoral trabecular failure by 21% and cortical failure by 5%. This reduction in failure was achieved with a 55% decrease in femoral neck failure and 14% in lateral cortex failure.

Conclusion

Our results indicate that cannulated hip screws in an inverted triangle formation may strengthen an osteoporotic proximal femur in the event of a lateral fall. Mechanical testing on cadaveric or composite models is required to validate these results.

Failure to Rescue in Geriatric Trauma: The Impact of Any Complication Increases with Age and Injury Severity in Elderly Trauma Patients

INTRODUCTION

The interaction of increasing age, Injury Severity Score (ISS), and complications is not well described in geriatric trauma patients. We hypothesized that failure to rescue rate from any complication worsens with age and injury severity.

METHODS

The National Trauma Data Bank (NTDB) was queried for injured patients aged 65 years or older from January 1, 2013 through December 31, 2016. Demographics and injury characteristics were used to compare groups. Mortality rates were calculated across subgroups of age and ISS, and captured with heatmaps. Multivariable logistic regression was performed to identify independent predictors of mortality.

RESULTS

614,496 geriatric trauma patients were included; 151,880 (24.7%) experienced a complication. Those with complications tended to be older, female, non-white, have non-blunt mechanism, higher ISS, and hypotension on arrival. Overall mortality was highest (19%) in the oldest (≥86 years old) and most severely injured (ISS ≥ 25) patients, with constant age increasing across each ISS group was associated with a 157% increase in overall mortality (P < .001, 95% CI: 148-167%). Holding ISS stable, increasing age group was associated with a 48% increase in overall mortality (P < .001, 95% CI: 44-52%). After controlling for standard demographic variables at presentation, the existence of any complication was an independent predictor of overall mortality in geriatric patients (OR: 2.3; 95% CI: 2.2-2.4).

CONCLUSIONS

Any complication was an independent risk factor for mortality, and scaled with increasing age and ISS in geriatric patients. Differences in failure to rescue between populations may reflect critical differences in physiologic vulnerability that could represent targets for interventions.

Radiological Outcome Measures Indicate Advantages of Precontoured Locking Compression Plates in Elderly Patients With Split-Depression Fractures to the Lateral Tibial Plateau (AO41B3)

Background

Split-depression fractures to the lateral tibial plateau (AO41B3) often feature severe joint surface destructions. Precontoured locking compression plates (LCPs) are designed for optimum support of the reduced joint surface and have especially been emphasized in reduced bone quality. A lack of evidence still inhibits their broad utilization in elderly patients. Thus, aim of the present study was to investigate the implant-specific radiological outcomes of AO41B3-fractures in young versus elderly patients.

Methods

The hospital’s database was screened for isolated AO41B3-factures, open reduction and internal fixation (ORIF), and radiological follow-up ≥12 months. CT-scans, radiographs, and patients’ records were analyzed. Patients were attributed as young (18–49) or elderly (≥50 years). Additional subgrouping was carried out into precontoured LCP and conventional implants. The Rasmussen Radiological Score (RRS) after 12 months was set as primary outcome parameter. The RRS postoperatively and the medial proximal tibial angle (MPTA) postoperatively and after 12 months were secondary outcome parameters.

Results

Fifty nine consecutive patients were included (26 young, 38.2 ± 7.8 years; 33 elderly, 61.3 ± 9.4 years). There were no significant differences regarding mean size and depression depth of the lateral joint surface fragments. Prior to implant-specific subgrouping, the radiological outcome measures revealed no significant differences between young (RRS = 7.7 ± 1.7; MPTA = 90.3 ± 2.3°) and elderly (RRS = 7.2 ± 1.7; MPTA = 90.5 ± 3.3°). After implant-specific subgrouping, the radiological outcome revealed significantly impaired results in young patients with conventional implants (RRS_(C) = 6.9 ± 1.6, RRS_(LCP) = 8.5 ± 1.5, P = .015; MPTA_(C) = 91.5 ± 1.9°, MPTA_(LCP) = 89.1 ± 2.1°, P = .01). The effect was even more pronounced in elderly patients, with highly significant deterioration of the radiological outcome measures for conventional implants compared to precontoured LCP (RRS_(C) = 5.7 ± 1.6, RRS_(LCP) = 8.2 ± .8, P < .001; MPTA_(C) = 92.6 ± 4.2°, MPTA_(LCP) = 89.2 ± 1.4°, P = .002).

Conclusion

Utilizing precontoured LCP in the treatment of AO41B3-fractures is associated with improved radiological outcomes. This effect is significant in young but even more pronounced in elderly patients. Consequently, precontoured LCP should closely be considered in any AO41B3-fracture, but especially in elderly patients.

Unplanned Readmissions to the Intensive Care Unit Among Geriatric Trauma Patients

BACKGROUND

Unplanned readmission/bounceback to the intensive care unit (ICUBB) is a prevalent issue in the medical community. The geriatric population is incompletely studied in regard to ICUBB. We sought to determine if ICUBB in older patients was associated with higher risk of mortality. We hypothesized that, of those who were older, those with ICUBB would have higher mortality compared to those with no ICUBB. Further, we hypothesized that of those with ICUBB, older age would lead to higher mortality.

METHODS

The Pennsylvania Trauma Outcome Study database was retrospectively queried from 2003 to 2018 for all trauma patients of age ≥40 years. Those with advance directives were excluded. Adjusted analysis in the form of logistic regressions controlling for demographic and injury covariates and clustering by facility were used to assess the adjusted impact of ICUBB and age on mortality.

RESULTS

363,778 patients were aged ≥40 years. When comparing mortalities between the age 40 and 49 years group and those in older groups, a dramatic increase in mortality was observed between those in each respective age category with ICUBB vs non-ICUBB. This trend was most prominent in those in the 90+ years age group (ICUBB: AOR: 34.78, P < .001; non-ICUBB: AOR: 9.08, P < .001). A second model only including patients who had ICUBB found that patients of age ≥65 years had significantly higher odds of mortality (AOR: 4.10, P < .001) when compared to their younger counterparts (age <65 years).

DISCUSSION

An ICUBB seems to exacerbate mortality rates as age increases. This profound increase in mortality calls for strategies to be developed, especially in the older population, to attempt to mitigate the factors leading to ICUBB.

Mortality, Risk Factors and Risk Assessment after Periprosthetic Femoral Fractures-A Retrospective Cohort Study

Periprosthetic femoral fracture (PFF) is a devastating complication. Here, the authors aimed to determine the influence of the timing of surgery as a risk factor for mortality and poor postoperative outcome in patients suffering from PFF. A retrospective descriptive analysis of patients treated for PFF between January 2010 and March 2018 was performed. In addition to patient and treatment characteristics, we assessed mortality rates and postoperative functional outcome by using the Harris Hip and WOMAC score. One-year mortality after PFF was 10.7%. Delayed surgery after 48 h did not negatively influence mortality after PFF. The postoperative hospital stay did not influence the mortality rate, nor did it correlate with medical scores of comorbidities, general health or functionalities. Cementation of stem correlated negatively with the WOMAC score. Deceased patients had a higher Charlson Comorbidity Index (CCI) score, while American society of Anaesthesiologists (ASA) scores did not show a significant difference. There were no differences between ORIF and revision arthroplasty. In conclusion, delayed surgery after 48 h does not negatively influence mortality after PFF. The CCI seems to be a suitable tool to assess patients’ risk for increased mortality after PFF, while the usually used ASA score is not able to achieve a relevant risk assessment.
