Risk factors and mortality of patients undergoing hip fracture surgery: a one-year follow-up study

Validation of the Charlson Comorbidity Index for the prediction of 30-day and 1-year mortality among patients who underwent hip fracture surgery

INTRODUCTION

The aim of our study was to validate the original Charlson Comorbidity Index (1987) (CCI) and adjusted CCI (2011) as a prediction model for 30-day and 1-year mortality after hip fracture surgery. The secondary aim of this study was to verify each variable of the CCI as a factor associated with 30-day and 1-year mortality.

METHODS

A prospective database of two-level II trauma teaching hospitals in the Netherlands was used. The original CCI from 1987 and the adjusted CCI were calculated based on medical history. To validate the original CCI and the adjusted CCI, the CCI was plotted against the observed 30-day and 1-year mortality, and the area under the curve (AUC) was calculated.

RESULTS

A total of 3523 patients were included in this cohort study. The mean of the original CCI in this cohort was 5.1 (SD ± 2.0) and 4.6 (SD ± 1.9) for the adjusted CCI. The AUCs of the prediction models were 0.674 and 0.696 for 30-day mortality for the original and adjusted CCIs, respectively. The AUCs for 1-year mortality were 0.705 and 0.717 for the original and adjusted CCIs, respectively.

CONCLUSIONS

A higher original and adjusted CCI is associated with a higher mortality rate. The AUC was relatively low for 30-day and 1-year mortality for both the original and adjusted CCIs compared to other prediction models for hip fracture patients in our cohort. The CCI is not recommended for the prediction of 30-day and 1-year mortality in hip fracture patients.

Systematic review and meta-analysis of preoperative predictors for early mortality following hip fracture surgery

Hip fractures are a global health problem with a high postoperative mortality rate. Preoperative predictors for early mortality could be used to optimise and personalise healthcare strategies. This study aimed to identify predictors for early mortality following hip fracture surgery. Cohort studies examining independent preoperative predictors for mortality following hip fracture surgery were identified through a systematic search on Scopus and PubMed. Predictors for 30-day mortality were the primary outcome, and predictors for mortality within 1 year were secondary outcomes. Primary outcomes were analysed with random-effects meta-analyses. Confidence in the cumulative evidence was assessed using the GRADE criteria. Secondary outcomes were synthesised narratively. Thirty-three cohort studies involving 462,699 patients were meta-analysed. Five high-quality evidence predictors for 30-day mortality were identified: age per year (OR: 1.06, 95% CI: 1.04-1.07), ASA score ≥ 3 (OR: 2.69, 95% CI: 2.12-3.42), male gender (OR: 2.00, 95% CI: 1.85-2.18), institutional residence (OR: 1.81, 95% CI: 1.31-2.49), and metastatic cancer (OR: 2.83, 95% CI: 2.58-3.10). Additionally, six moderate-quality evidence predictors were identified: chronic renal failure, dementia, diabetes, low haemoglobin, heart failures, and a history of any malignancy. Weak evidence was found for non-metastatic cancer. This review found relevant preoperative predictors which could be used to identify patients who are at high risk of 30-day mortality following hip fracture surgery. For some predictors, the prognostic value could be increased by further subcategorising the conditions by severity.

What interventions add value in lateral compression type 1 fragility pelvis fractures? A retrospective cohort study

Introduction

Fragility fractures are a large source of morbidity and mortality in the elderly. Orthopaedic surgeons are regularly the main point of contact in patients with lateral compression type 1 pelvis fractures, despite many of these being treated non-operatively. This study aims to identify risk factors for mortality and elucidate which follow-up visits have the potential to improve care for these patients.

Methods and materials

In all, 211 patients have been identified with fragility lateral compression type 1 fractures at a level 1 trauma centre over a 5-year period. For all patients, we recorded patient demographics, imaging data, hospital readmissions, medical complications and death dates if applicable.

Results

Of the 211 patients identified, 56.4% had at least one orthopaedic follow-up, of which no patient had a clinically meaningful medical intervention initiated. 30-day readmission rate was 19%, and 1-year mortality was 24%. Male sex, need for an assist device, higher Charlson Comorbidity Index and increased age were found to be statistically associated with increased risk of mortality. Patients who followed up with their primary care physician were found to have a statistically lower risk of mortality. Computed tomography scans were obtained in 70% of patients and never limited patient weight-bearing status or found any additional injury not already identified on the radiograph.

Discussion/Conclusions

For patients with lateral compression type 1 type fragility fractures, orthopaedic surgeons did not offer additional clinically meaningful intervention after the time of initial diagnosis in this patient cohort. The rate of clinical follow-up with a primary care physician is relatively low despite high rates of medical comorbidity. Computed tomography scans were utilised frequently but did not change recommendations. The high rate of medical complications and lack of orthopaedic intervention suggest that we should re-evaluate the role of the orthopaedic surgeon versus the primary care physician as the primary point of medical contact for patients with these injuries.

Biomechanical evaluation of a new intramedullary nail compared with proximal femoral nail antirotation and InterTAN for the management of femoral intertrochanteric fractures

Purpose: Surgical treatment is the main treatment method for femoral intertrochanteric fractures (FIFs), however, there are lots of implant-related complications after surgery. Our team designed a new intramedullary nail (NIN) to manage such fractures. The purpose of this study was to introduce this new implant and compare it with proximal femoral nail antirotation (PFNA) and InterTAN for treating FIFs. Methods: An AO/OTA 31-A1.3 FIF model was built and three fixation models were created via finite element method, comprising PFNA, InterTAN, and the NIN. Vertical, anteroposterior (A-P) bending, and torsional loads were simulated and applied to the three fixation models. Displacement and stress distribution were monitored. In order to compare PFNA and the NIN deeply, finite element testing was repeated for five times in vertical load case. Results: The finite element analysis (FEA) data indicated that the NIN possessed the most outstanding mechanical properties among the three fixation models. The NIN model had lower maximal stress at implants compared to PFNA and InterTAN models under three load conditions. The trend of maximal stress at bones was similar to that of maximal stress at implants. Besides, the NIN model showed smaller maximal displacement compared with PFNA and InterTAN models under vertical, A-P bending, and torsional load cases. The trend for maximal displacement of fracture surface (MDFS) was almost identical with that of maximal displacement. In addition, there was significant difference between the PFNA and NIN groups in vertical load case (p < 0.05). Conclusion: Compared with PFNA and InterTAN, the NIN displayed the best mechanical properties for managing FIFs, including the lowest von Mises stress at implants and bones, and the smallest maximal displacement and MDFS under vertical, A-P bending, and torsional load cases. Therefore, this study might provide a new choice for patients with FIFs.

HIP fracture Supplemental Therapy to Enhance Recovery (HIPSTER): a protocol for a randomised controlled trial

INTRODUCTION

Hip fractures result in substantial health impacts for patients and costs to health systems. Many patients require prolonged hospital stays and up to 60% do not regain their prefracture level of mobility within 1 year. Physical rehabilitation plays a key role in regaining physical function and independence; however, there are no recommendations regarding the optimal intensity. This study aims to compare the clinical efficacy and cost-effectiveness of early intensive in-hospital physiotherapy compared with usual care in patients who have had surgery following a hip fracture.

METHODS AND ANALYSIS

This two-arm randomised, controlled, assessor-blinded trial will recruit 620 participants who have had surgery following a hip fracture from eight hospitals. Participants will be randomised 1:1 to receive usual care (physiotherapy according to usual practice at the site) or intensive physiotherapy in the hospital over the first 7 days following surgery (two additional sessions per day, one delivered by a physiotherapist and the other by an allied health assistant). The primary outcome is the total hospital length of stay, measured from the date of hospital admission to the date of hospital discharge, including both acute and subacute hospital days. Secondary outcomes are functional mobility, health-related quality of life, concerns about falling, discharge destination, proportion of patients remaining in hospital at 30 days, return to preadmission mobility and residence at 120 days and adverse events. Twelve months of follow-up will capture data on healthcare utilisation. A cost-effectiveness evaluation will be undertaken, and a process evaluation will document barriers and facilitators to implementation.

ETHICS AND DISSEMINATION

The Alfred Hospital Ethics Committee has approved this protocol. The trial findings will be published in peer-reviewed journals, submitted for presentation at conferences and disseminated to patients and carers.

Is It Safe to Resume Direct Oral Anticoagulants upon Discharge after Hip Fracture Surgery? A Retrospective Study

This study aimed to examine the incidence rate of early reoperations following hip fracture surgery and determine the safety of resuming direct oral anticoagulants. Many orthopedic surgeons are reluctant to resume chronic anticoagulation therapy for patients after surgical intervention for hip fractures. One of the main reasons is the potential for reoperation in the case of surgical complications. We conducted a retrospective cohort study at an Academic Level I trauma center, reviewing the records of 425 geriatric patients (age > 60) who underwent hip fracture surgery between 2018 and 2020, including a subgroup treated with direct oral anticoagulants prior to hospitalization. The study assessed the incidence rate of complications requiring early reoperation. Out of the 425 patients, only nine (2%) required reoperation within a month after discharge, with two (0.5%) on chronic anticoagulation therapy. None of the reoperations were urgent, and all were performed at least 24 h after re-admission. The findings revealed a very low incidence rate of reoperations in patients who underwent hip fracture surgery, with no reoperations performed within 24 h of re-admission. Consequently, we believe that resuming chronic direct oral anticoagulants is a safe and effective approach when discharging patients after hip fracture surgery.

Perioperative peri-implant fracture after osteosynthesis for geriatric femoral pertrochanteric fracture with the linear compression integrated screw intramedullary nail system (INTERTAN™): a retrospective study

BACKGROUND

Osteosynthesis for geriatric femoral pertrochanteric fractures using the linear compression integrated screw intramedullary nail system (INTERTAN™) has become popular. Nonetheless, cases of perioperative peri-implant fractures have been reported following this surgical technique. The factors responsible for this complication remain unclear. Therefore, we investigated perioperative peri-implant fracture risk factors and incidence, as well as overall outcomes, using the INTERTAN™ system for geriatric femoral pertrochanteric fractures.

METHODS

We retrospectively reviewed 98 consecutive patients with geriatric femoral pertrochanteric fractures after INTERTAN™ fixation, with at least a 12-month follow-up period between May 2020 and April 2022 at a single medical institute. The patients' demographic characteristics, fracture pattern, quality of reduction, quality of fixation, nail length, morphology of the femur, and perioperative complications were recorded and analyzed.

RESULTS

Among the 98 patients, 92 achieved union during follow-up. Twelve perioperative peri-implant fractures (12.2%) were recorded, all of which occurred during or within 1 month of osteosynthesis. Except for one patient who underwent re-osteosynthesis, the others underwent nonoperative treatment, and all achieved union. Multiple regression analysis revealed morphology of the femur with low-lesser trochanter width (odds ratio (OR) 0.532, 95% confidence interval (CI) 0.33-0.86, p = 0.01) to be the only factor contributing to perioperative peri-implant fractures. When the Youden index was used, the optimal cut-off value was 20.2 mm of low-lesser trochanter width. Low-lesser trochanter width < 20.2 mm was found to be a potential factor causing perioperative peri-implant fractures (OR 17.81, 95% CI 1.67-19.76, p = 0.017).

CONCLUSIONS

Morphology of the femur with a low-lesser trochanter width smaller than 20.2 mm was found to be the only potential contributor to perioperative peri-implant fractures when using INTERTAN™ for geriatric femoral pertrochanteric fractures. Care should be taken during osteosynthesis, focusing not only on the fracture site but also on the femoral cortex around the implant. Although perioperative peri-implant fractures were observed within one month following osteosynthesis, the majority of these cases were effectively treated without surgical intervention.

Comparing the Effect of Spinal and General Anesthesia for Hip Fracture Surgery in Older Patients: A Meta-analysis of Randomized Clinical Trials

OBJECTIVE

Hip fractures are the most common fractures among older adults, with most patients undergoing surgery. The debate regarding the type of anesthetic technique for hip fracture surgery is still ongoing. This meta-analysis aimed to compare the intraoperative and postoperative outcomes of spinal and general anesthesia in older patients undergoing hip fracture surgery.

METHODS

Eligible studies that compared the effects of spinal and general anesthesia were systematically searched from PubMed, Embase, and the Cochrane Library until May 27, 2022. The intraoperative and postoperative outcomes of the two anesthesia techniques were compared. Quality assessment, heterogeneity analysis, and publication bias of the studies were also assessed.

RESULTS

Nine articles of methodological quality were included in the meta-analysis. The pooled results revealed that there were significant differences in hypotension (risk ratio [RR] (95% confidence interval [CI]) = 0.81 (0.68, 0.97), p = 0.02) and ephedrine dose (weighted mean difference [WMD] [95%CI] = -20.94 [-37.50, -4.37] mg, p = 0.01) between the spinal and general anesthesia groups. However, no significant differences were observed in the use of ephedrine (RR [95% CI] = 0.77 [0.19, 3.05]), blood loss (WMD [95%CI] = -34.38 [-89.56, 20.80) mL], myocardial infarction (RR [95% CI] = 0.78 [0.31, 1.94] mL), heart failure (RR [95% CI] = 0.87 [0.17, 4.36] mL), stroke (RR [95%CI) = 0.65 [0.22, 1.95] mL), postoperative nausea and vomiting (RR [95% CI] = 0.88 [0.17, 4.35] mL), delirium (RR [95% CI] = 1.08 [0.89, 1.31] mL), and mortality (RR [95% CI] = 1.10 [0.72, 1.68] mL) (all p < 0.05). No publication bias was observed in any of the included studies.

CONCLUSION

Compared to general anesthesia, spinal anesthesia was associated with a lower risk of intraoperative hypotension and lower doses of ephedrine in older patients undergoing hip fracture surgery.

Comparison of mortality rate and septic and aseptic revisions in total hip arthroplasties for osteoarthritis and femoral neck fracture: an analysis of the German Arthroplasty Registry

BACKGROUND

Indications for total hip arthroplasties (THA) differ from primary osteoarthritis (OA), which allows elective surgery through femoral neck fractures (FNF), which require timely surgical care. The aim of this investigation was to compare mortality and revisions in THA for primary OA and FNF.

METHODS

Data collection for this study was performed using the German Arthroplasty Registry (EPRD) with analysis THA for the treatment of FNF and OA. Cases were matched 1:1 according to age, sex, body mass index (BMI), cementation, and the Elixhauser score using Mahalanobis distance matching.

RESULTS

Overall 43,436 cases of THA for the treatment of OA and FNF were analyzed in this study. Mortality was significantly increased in FNF, with 12.6% after 1 year and 36.5% after 5 years compared with 3.0% and 18.7% in OA, respectively (p < 0.0001). The proportion for septic and aseptic revisions was significantly increased in FNF (p < 0.0001). Main causes for an aseptic failure were mechanical complications (OA: 1.1%; FNF: 2.4%; p < 0.0001) and periprosthetic fractures (OA: 0.2%; FNF: 0.4%; p = 0.021). As influencing factors for male patients with septic failure (p < 0.002), increased BMI and Elixhauser comorbidity score and diagnosis of fracture (all p < 0.0001) were identified. For aseptic revision surgeries, BMI, Elixhauser score, and FNF were influencing factors (p < 0.0001), while all cemented and hybrid cemented THA were associated with a risk reduction for aseptic failure within 90 days after surgery (p < 0.0001).

CONCLUSION

In femoral neck fractures treated with THA, a significant higher mortality, as well as septic and aseptic failure rate, was demonstrated compared with prosthesis for the therapy of osteoarthritis. Increased Elixhauser comorbidity score and BMI are the main influencing factors for development of septic or aseptic failure and can represent a potential approach for prevention measures.

Reduced cutout for reverse oblique intertrochanteric hip fractures treated with trochanteric fixation advanced (TFN-A) nail compared to the short gamma-3 nail

BACKGROUND

Reverse oblique fractures (AO/OTA 31-A3) account for 5-23% of all intertrochanteric fractures and are challenging to manage. The Gamma 3-Proximal Femoral Nail (GPFN) and the Trochanteric Fixation Nail Advanced (TFNA) are two common cephalomedullary systems used to treat this fracture. No study has reported on outcomes with the TFN-A for reverse oblique fractures. This study aimed to compare outcomes and complication rates in patients with reverse oblique fractures, treated with either TFNA or GPFN.

PATIENTS AND METHODS

A total of 203 patients with reverse oblique fractures (137 in the GPFN group and 66 in the TFNA group), were treated in our institution between June 2010 and May 2019. Data was collected on postoperative radiological variables including screw or blade location, and tip-apex distance (TAD). Data were also collected for non-orthopaedic complication rates and orthopaedic complications. A sub-group analysis was additionally performed for different nail lengths.

RESULTS

We found no significant difference in the overall rate of complications and revisions between the two groups. Patients treated with the 235 mm TFN-A nail sustained lower rates of cutout, compared to 180 mm GPFN (GPFN: 6% TFN-A: 0%, p = 0.043). The frequency of revision surgeries and malunions/non-unions did not differ significantly between the two groups and additionally showed no difference in the subgroup analysis.

CONCLUSION

The 235 mm TFN-A was associated with lower rates of cut-out compared to the short GPFN for reverse oblique intertrochanteric fractures. Future well-designed prospective studies are warranted to investigate the role of the TFN-A in improving outcomes for such fractures.

Treatment of Trochanteric Hip Fractures with Cephalomedullary Nails: Single Head Screw vs. Dual Integrated Compression Screw Systems

Extracapsular hip fractures are very common in the elderly. They are mainly treated surgically with an intramedullary nail. Nowadays, both endomedullary hip nails with single cephalic screw systems and interlocking double screw systems are available on the market. The latter are supposed to increase rotational stability and therefore decrease the risk of collapse and cut-out. A retrospective cohort study was carried out, in which 387 patients with extracapsular hip fracture undergoing internal fixation with an intramedullary nail were included to study the occurrence of complications and reoperations. Of the 387 patients, 69% received a single head screw nail and 31% received a dual integrated compression screw nail. The median follow-up was 1.1 years, and in that time, a total of 17 reoperations were performed (4.2%; 2.1% for single head screw nails vs. 8.7% for double head screws). According to the multivariate logistic regression model adjusted for age, sex and basicervical fracture, the adjusted hazard risk of reoperation required was 3.6 times greater when using double interlocking screw systems (p = 0.017). A propensity scores analysis confirmed this finding. In conclusion, despite the potential benefits of using two interlocking head screw systems and the increased risk of reoperation in our single center, we encourage to other researchers to explore this question in a wider multicenter study.

Epidemiology of elderly fractures in a tertiary hospital in Northern Ghana: a 3-year retrospective descriptive review

PURPOSE

The incidence of elderly fractures is closely related to the increasing proportion of the elderly population in sub-Saharan Africa, making it a relevant public health concern. Epidemiological profiles of these fractures and treatment options are necessary for resource-poor settings to optimise planning and patient care.

METHODS

A retrospective descriptive cross-sectional study was conducted at Tamale Teaching Hospital. Data of 69 elderly patients (60 years and above) with fractures admitted to the trauma and orthopaedic unit from January 2017 to December 2019 were collected. Simple descriptive and bivariate analysis was conducted on some variables, whereas the Chi-square was used to test for some associations for categorical data.

RESULTS

The mean age of the study participants was 70.3(± 8.6). Elderly males (55.1%) were three times more likely to sustain fractures than females. The primary mechanism of injury was a road traffic accident (RTA) (59.4%), followed by falls from slips (29.0%). There was a significant association between gender and mechanisms (RTA and Falls from slips) of injury (p = 0.002). The most fractured bone was the femur (50.7%). Hip fractures (33.3%) were more common among females than males and mainly among the (71-80) age group. Open fractures were more common among males than females.

CONCLUSION

RTAs were the most typical cause of fractures in the elderly. Contrary to other studies, males were more commonly involved in accidents than females, albeit females were the majority for hip fractures. Therefore, significant public health policies with resource allocation should address the unmet health needs of this unique age group in our growing populations in low- and middle-income countries.

Intertrochanteric Femoral Fractures: A Comparison of Clinical and Radiographic Results with the Proximal Femoral Intramedullary Nail (PROFIN), the Anti-Rotation Proximal Femoral Nail (A-PFN), and the InterTAN Nail

Background and Objectives: The aim of this study was to evaluate retrospectively the radiological and functional outcomes of closed reduction and internal fixation for intertrochanteric femoral fractures (IFF) using three different proximal femoral nails (PFN). Materials and Methods: In total, 309 individuals (143 males and 166 females) who underwent surgery for IFF using a PFN between January 2018 and January 2021 were included in the study. Our surgical team conducted osteosynthesis using the A-PFN® (TST, Istanbul, Turkey) nail, the PROFIN® (TST, Istanbul, Turkey), and the Trigen InterTAN (Smith & Nephew, Memphis, TN, USA) nail. The PFNs were compared based on age, gender, body mass index (BMI), length of stay (LOS) in intensive care, whether to be admitted to intensive care, mortality in the first year, amount of transfusion, preoperative time to surgery, hospitalisation time, duration of surgery and fluoroscopy, fracture type and reduction quality, complication ratio, and clinical and radiological outcomes. The patients’ function was measured with the Harris Hip Score (HHS) and the Katz Index of Independence in Activities of Daily Living (ADL). Results: Pain in the hip and thigh is the most common complication, followed by the V-effect. The Z-effect was seen in 5.7% of PROFIN patients. A-PFN was shown to have longer surgical and fluoroscopy durations, lower HHS values, and much lower Katz ADL Index values compared to the other two PFNs. The V-effect occurrence was significantly higher in the A-PFN group (36.7%) than in the InterTAN group. The V-effect was seen in 33.1% of 31A2-type fractures but in none of the 31A3-type fractures. Conclusions: InterTAN nails are the best choice for IFFs because they have high clinical scores after surgery, there is no chance of Z-effect, and the rate of V-effect is low.

Cemented vs Uncemented hemiarthroplasties for femoral neck fractures: An overlapping systematic review and evidence appraisal

BACKGROUND

The purpose of our study is to assess the methodology of overlapping systematic reviews related to cemented vs uncemented hip hemiarthroplasties for the treatment of femoral neck fractures to find the study with the best evidence. Also, we assess the gaps in methodology and information to help with direction of future studies.

METHODS

A systematic search was conducted in September 2022 using Pubmed, Embase, and Cochrane Library. Clinical outcome data and characteristics of each study were extracted to see which treatment had better favorability. The outcomes and characteristics extracted from each study includes, first author, search date, publication journal and date, number of studies included, databases, level of evidence, software used, subgroup analyses that were conducted, and heterogeneity with the use of I2 statistics Methodological quality information was extracted from each study using four different methodologic scores (Oxford Levels of Evidence; Assessment of Multiple Systematic Reviews (AMSTAR); Quality of reporting of meta-analyses (QUROM); Oxman and Guyatt. After that, the Jadad decision algorithm was used to identify which studies in our sample contained the best available evidence. Finally, overlap of each systematic review was assessed using Corrected Covered Area (CCA) to look at redundancy and research waste among the systematic reviews published on the topic.

RESULTS

After screening, 12 studies were included in our sample. For the Oxford Levels of Evidence, we found that all the studies were Level I evidence. For the QUORUM assessment, we had 1 study with the highest score of 18. Additionally, we did the Oxman and Guyatt assessment, where we found 4 studies with a maximum score of 6. Finally, we did an AMSTAR assessment and found 2 studies with a score of 9. After conducting the methodological scores; the authors determined that Li. L et al 2021 had the highest quality. In addition, it was found that the CCA found among the primary studies in each systematic review calculated to .22. Any CCA above .15 is considered "very high overlap".

CONCLUSIONS

The best available evidence suggests that Cemented HAs are better at preventing Prosthesis-related complications. Conversely, the best evidence also suggests that Cemented HA also results in longer operative time and increased intraoperative blood loss. When conducting future systematic reviews related to the topic, we ask that authors restrict conducting another systematic review until new evidence emerges so as not to confuse the clinical decision-making of physicians.

Blood loss and transfusion risk in intramedullary nailing for subtrochanteric fractures

BACKGROUND

The incidence of hip fractures and subtrochanteric fractures in particular is increasing, along with the globally expanding aging population. Intramedullary nailing remains the 'gold standard' of their treatment. Blood loss can be a result of the original trauma, but also secondary to the subsequent surgical insult, especially during the reaming of the intramedullary canal.

OBJECTIVES

The aim of our study was to report on the blood loss and incidence of blood transfusion in patients presenting with a subtrochanteric fracture treated with intramedullary nailing. Most importantly, we aim to identify factors associated with the need for transfusion within the first 48 h post-operatively.

METHODS

Following institutional board approval, 431 consecutive patients (131 males; age: 79.03 years old, SD 13.68 years) presenting in a Level 1 Trauma Centre with a subtrochanteric fracture treated with an intramedullary nail were retrospectively identified, over an 8-year period. Exclusion criteria included patients with high energy injuries, pathological fractures, primary operations at other institutions and patients lost to follow-up. To identify risk factors leading to increased risk of transfusion, we first compared patients requiring intra-operative transfusion or transfusion during the first 48 h post-operatively against those who did not require transfusion. This was then followed by multivariate regression analysis adjusted for confounding factors to identify the most important risk factors associated with need for transfusion within the first 48 h post-operatively.

RESULTS

Incidence of blood transfusion was 6.0% pre-operatively, compared to 62.7% post-operatively. A total of 230 patients (52.3%) required either intra-operative transfusion or transfusion during the first 48 h following surgery. Patients having a transfusion within the first 48 h post-operatively had a higher incidence of escalation in their care (p = 0.050), LOS (p = 0.015), 30-day (p = 0.033) and one-year mortality (p = 0.004). Multivariate regression analysis adjusted for confounding factors identified that the most important association of a need for transfusion within the first 48 post-operative hours was a pre-operative Hb <100 g/L (OR 6.64); a nail/canal ratio <70% (OR 3.92), followed by need for open reduction (OR 2.66). Fracture involving the lesser trochanter was also implicated with an increased risk (OR 2.08). Additionally, pre-operative moderate/severe renal impairment (OR 4.56), as well as hypoalbuminaemia on admission (OR 2.10) were biochemical predictors of an increased risk of transfusion. Most importantly, the need for transfusion was associated with an increase in 30-day mortality (OR 12.07).

CONCLUSION

Several patient, fracture and surgery related factors are implicated with an increased risk for transfusion within the first 48-h post-operatively. Early identification, and where possible correction of these factors can potentially reduce blood loss and risk of transfusion, along with all the associated sequelae and mortality risk.

Relationship between the neutrophil-to-lymphocyte ratio or platelet-to-lymphocyte ratio and deep venous thrombosis (DVT) following femoral neck fractures in the elderly

Purpose

This study aimed to investigate whether the neutrophil-to-lymphocyte ratio (NLR) or platelet-to-lymphocyte ratio (PLR) was associated with deep venous thrombosis (DVT) following femoral neck fractures in the elderly.

Method

This was a retrospective cohort study and used data extracted from the hospitalization electronic medical record and the laboratory biomarker reports. Patients were included if they were aged above 60 years with a definite diagnosis of femoral neck fracture caused by low-energy trauma. Duplex ultrasound scanning was routinely performed to detect the potential DVT. Two independent multivariate logistic regression models were constructed to identify the association of NLR or PLR with the risk of DVT.

Results

A total of 708 patients with femoral neck fractures were included, and 112 were found to have DVT, indicating an incidence rate of 15.8%. There were significant differences across five subgroups for NLR or PLR, in terms of age (p = 0.020, 0.006), white blood cell (p < 0.001, =0.006), hemoglobin (p < 0.001, <0.001), and albumin (p < 0.001, <0.001). BMI was tested to be significantly different across subgroups for NLR (p = 0.030) and prevalence of cerebrovascular disease for PLR (p = 0.014). The multivariate analyses demonstrated that not NLR but PLR in Q3 (range, 179–238) was associated with an increased risk of DVT, and the risk for the latter was 1.86 (95%CI, 1.07–3.36).

Conclusion

We concluded that a PLR value of 179–238 was associated with a 1.86-fold increased risk of DVT after femoral neck fracture. This study paves the way toward further exploration of inflammatory/immune biomarkers with the risk of DVT in the elderly with trauma.

Intertrochanteric fracture fixation in solid organ transplant patients: outcomes and survivorship

BACKGROUND

Solid organ transplantation (SOT) recipients have complex medical and surgical risk factors; however, the outcomes of these patients undergoing surgical fixation of hip fractures are unknown. This study sought to evaluate SOT patients' outcomes and survivorship after intertrochanteric (IT) fracture fixation.

METHODS

A retrospective review identified 12 SOT patients who underwent cephalomedullary (CMN) nail fixation for IT fractures and were matched (1:2) to a cohort of 24 non-SOT IT fracture patients. Perioperative results and complications, mortality/patient survivorship, and clinical outcomes were compared between the cohorts.

RESULTS

The time from presentation to surgical fixation was within 48 h of presentation for the non-SOT patients, while only 75% of SOT patients underwent surgery within 48 h of presentation (p = 0.034). The 90-day readmission rate for SOT patients was 25% versus 13% in the non-SOT group (p = 0.38). Similarly, the SOT cohort experienced a higher rate of major medical complication (25% vs. 13%, p = 0.38). There were two (16%) reoperations in the SOT group and three (13%) in the non-SOT matched group (p = 0.99). Respectively, the 90-day and 1-year estimated patient survivorship was similar between the two cohorts: SOT patients with 92% (95% CI 54-99%) and 73% (95% CI 24-93%) versus 86% (95% CI 62-95%) and 72% (95% CI 47-86%, HR 0.92, 95% CI 0.18-4.62, p = 0.92) in non-SOT patients.

CONCLUSION

SOT patients who underwent CMN fixation for IT fractures required more time from hospital presentation to surgical management than non-SOT patients. Although not statistically significant, SOT patients demonstrated more acute complications and readmissions, but similar mortality compared to those without transplant.

Increased postoperative glycemic variability is associated with increased mortality in diabetic patients undergoing hip arthroplasty for hip fracture

BACKGROUND

Increased glycemic variability (GV) during hospitalization has been associated with increased rates of surgical site and periprosthetic joint infections (PJI) following elective total joint arthroplasty. Uncertainty exists surrounding GV as a predictor for complications in urgent arthroplasty cases following hip fractures. In this study, we evaluated the association between GV and postoperative complications in diabetic patients undergoing total hip arthroplasty (THA) and hemiarthroplasty (HA) for hip fractures.

METHODS

We analyzed data on 2421 consecutive patients who underwent THA or HA at our institution from 2011 to 2020. Patients with a known diagnosis of diabetes mellitus who had a minimum of three postoperative glucose values taken within the first week after surgery were included. GV was assessed using a coefficient of variation. Outcomes included short- and long-term mortality, reoperations, prosthetic joint infection (PJI) requiring revision and readmissions for any cause.

RESULTS

The final cohort consisted of 482 patients (294 females, 188 males). Higher GV was associated with an increased 90-day mortality (p = 0.017). GV was not associated with 30-day mortality (p = 0.45), readmissions of any cause at 30 or 90 days (p = 0.99, p = 0.91, respectively), reoperation of any cause (p = 0.91) or PJI requiring revision surgery (p = 0.42).

CONCLUSIONS

Higher GV in the postoperative period is associated with increased rates of mortality in diabetic patients following THA and HA for hip fractures. Efforts should be made to monitor and control glucose variability in the postoperative period.

A New Random Forest Algorithm-Based Prediction Model of Post-operative Mortality in Geriatric Patients With Hip Fractures

Background

Post-operative mortality risk assessment for geriatric patients with hip fractures (HF) is a challenge for clinicians. Early identification of geriatric HF patients with a high risk of post-operative death is helpful for early intervention and improving clinical prognosis. However, a single significant risk factor of post-operative death cannot accurately predict the prognosis of geriatric HF patients. Therefore, our study aims to utilize a machine learning approach, random forest algorithm, to fabricate a prediction model for post-operative death of geriatric HF patients.

Methods

This retrospective study enrolled consecutive geriatric HF patients who underwent treatment for surgery. The study cohort was divided into training and testing datasets at a 70:30 ratio. The random forest algorithm selected or excluded variables according to the feature importance. Least absolute shrinkage and selection operator (Lasso) was utilized to compare feature selection results of random forest. The confirmed variables were used to create a simplified model instead of a full model with all variables. The prediction model was then verified in the training dataset and testing dataset. Additionally, a prediction model constructed by logistic regression was used as a control to evaluate the efficiency of the new prediction model.

Results

Feature selection by random forest algorithm and Lasso regression demonstrated that seven variables, including age, time from injury to surgery, chronic obstructive pulmonary disease (COPD), albumin, hemoglobin, history of malignancy, and perioperative blood transfusion, could be used to predict the 1-year post-operative mortality. The area under the curve (AUC) of the random forest algorithm-based prediction model in training and testing datasets were 1.000, and 0.813, respectively. While the prediction tool constructed by logistic regression in training and testing datasets were 0.895, and 0.797, respectively.

Conclusions

Compared with logistic regression, the random forest algorithm-based prediction model exhibits better predictive ability for geriatric HF patients with a high risk of death within post-operative 1 year.

Functional Status in Older Persons After Hip Fracture Surgery: A Longitudinal Study of Indonesian Patients

BACKGROUND

Hip fractures are one of the most serious injuries affecting older adults. Evidence-based knowledge regarding the functional status of older persons after hip fracture can provide information critical for developing effective continuous-care and rehabilitation programs.

PURPOSE

This study was developed to examine the post-hospital-discharge outcome measures and predictors of functional status in older adults in Indonesia after hip fracture surgery.

METHODS

The functional status of 109 patients discharged from an orthopedic hospital in Indonesia after hip fracture surgery was evaluated in this prospective cohort study. Functional status was evaluated using measures of physical and independent activities of daily living (PADL and IADL, respectively) at 1, 3, and 6 months postdischarge. Predictors of changes in functional status, including age, length of hospital stay, comorbidity, prefracture walking ability, type of surgery, status of depression and nutrition, type of insurance, and residential status (urban vs. rural), were also examined. Data were analyzed using generalized estimating equations.

RESULTS

Significant improvements in PADL were found at 3 and 6 months, and significant improvements in IADL were found at 6 months. Predictors of poor outcomes found in this study included age, a dependent prefracture walking ability, depression, and having public health insurance.

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

The findings of this study support the effectiveness of using presurgery assessments to identify individuals at a higher postdischarge risk of having poor PADL and IADL outcomes. Home nursing or subacute rehabilitation is recommended to improve and maintain functional status in older persons after hip fracture surgery. In addition, interventions and rehabilitation should take into consideration different recovery periods for PADL and IADL after hospital discharge after hip fracture surgery.

Implementation of a Multidisciplinary "Code Hip" Protocol is Associated with Decreased Time to Surgery and Improved Patient Outcomes

Background:

The purpose of this study is to report outcomes data based on the implementation of a “Code Hip” protocol, a multidisciplinary approach to the care of fragility hip fracture patients focussing on medical optimization and early operative intervention. We hypothesized that implementation of this protocol would decrease time from presentation to surgical intervention and improve outcomes based on short term post-operative data.

Methods:

A retrospective chart review was performed on all patients aged greater than 65 years old with a fragility hip fracture from October 2015 through June 2018. In addition to demographic and patient factors, we recorded time to surgery, type of surgical interventions performed, ability to ambulate in the post-operative period, 90-day post-operative complications and overall hospital cost.

Results:

There were 114 patients in the pre-Code Hip cohort and 132 patients in the post-Code Hip cohort. Demographic factors were not different between the 2 cohorts. Time from presentation to surgery in the post-Code Hip cohort was shorter at 23.1 ± 16.4 hours versus 33.2 ± 27.2 hours (p < 0.001). 30.3% of patients in the post-Code Hip cohort had at least one post-operative complication compared to 42.1% in the pre-Code Hip cohort (RR = 0.72, CI = 0.51 -1.01, p = 0.05). The post-Code Hip cohort had a significantly lower rate of hospital readmission (p = 0.04), unplanned reoperation (p = 0.02), surgical site infection (p = 0.03), and sepsis (p = 0.05). Total hospital cost per patient decreased from an average of $14,079 +/- $10,305 pre-Code Hip cohort to $11,744 +/- $4,174 per patient in the post-Code Hip cohort (p = 0.02).

Conclusions:

Implementation of our Code Hip protocol, which invokes a multidisciplinary approach to the elderly patient with a fragility hip fracture, is associated with shorter times from presentation to surgery, increased ability to ambulate post-operatively, decreased short term post-operative complication, and decreased hospital costs.

International comparison of spending and utilization at the end of life for hip fracture patients

OBJECTIVE

To identify and explore differences in spending and utilization of key health services at the end of life among hip fracture patients across seven developed countries.

DATA SOURCES

Individual-level claims data from the inpatient and outpatient health care sectors compiled by the International Collaborative on Costs, Outcomes, and Needs in Care (ICCONIC).

STUDY DESIGN

We retrospectively analyzed utilization and spending from acute hospital care, emergency department, outpatient primary care and specialty physician visits, and outpatient drugs. Patterns of spending and utilization were compared in the last 30, 90, and 180 days across Australia, Canada, England, Germany, New Zealand, Spain, and the United States. We employed linear regression models to measure age- and sex-specific effects within and across countries. In addition, we analyzed hospital-centricity, that is, the days spent in hospital and site of death.

DATA COLLECTION/EXTRACTION METHODS

We identified patients who sustained a hip fracture in 2016 and died within 12 months from date of admission.

PRINCIPAL FINDINGS

Resource use, costs, and the proportion of deaths in hospital showed large variability being high in England and Spain, while low in New Zealand. Days in hospital significantly decreased with increasing age in Canada, Germany, Spain, and the United States. Hospital spending near date of death was significantly lower for women in Canada, Germany, and the United States. The age gradient and the sex effect were less pronounced in utilization and spending of emergency care, outpatient care, and drugs.

CONCLUSIONS

Across seven countries, we find important variations in end-of-life care for patients who sustained a hip fracture, with some differences explained by sex and age. Our work sheds important insights that may help ongoing health policy discussions on equity, efficiency, and reimbursement in health care systems.

30-day and 1-year mortality after skeletal fractures: a register study of 295,713 fractures at different locations

Background and purpose - Few studies have reported the mortality rate after skeletal fractures involving different locations, within the same population. We analyzed the 30-day and 1-year mortality rates following different fractures.Patients and methods - We included 295,713 fractures encountered in patients 16-108 years of age, registered in the Swedish Fracture Register (SFR) from 2012 to 2018. Mortality rates were obtained by linkage of the SFR to the Swedish Tax Agency population register. The standardized mortality ratios (SMR) at 30 days and 1 year were calculated for fractures in any location and for each of 27 fracture locations, using age- and sex-life tables from Statistics Sweden (www.scb.se).Results - The overall SMR at 30 days was 6.8 (95% CI 6.7-7.0) and at 1 year 2.2 (CI 2.2-2.2). The SMR was > 2 for 19/27 and 13/27 of the fracture locations at 30 days and 1 year, respectively. Humerus, femur, and tibial diaphysis fractures were all associated with high SMR, at both 30 days and 1 year.Interpretation - Patients sustaining a fracture had approximately a 7-fold increased mortality at 30 days and over 2-fold increased mortality at 1 year as compared with what would be expected in the general population. High mortality rates were seen for patients with axial skeletal and proximal extremity fractures, indicating frailty in these patient groups.

An international comparison of long-term care trajectories and spending following hip fracture

OBJECTIVE

The objectives of this study are to compare the relative use of different postacute care settings in different countries and to compare three important outcomes as follows: total expenditure, total days of care in different care settings, and overall longevity over a 1-year period following a hip fracture.

DATA SOURCES

We used administrative data from hospitals, institutional and home-based long-term care (LTC), physician visits, and medications compiled by the International Collaborative on Costs, Outcomes, and Needs in Care (ICCONIC) from five countries as follows: Canada, France, Germany, the Netherlands, and Sweden.

DATA EXTRACTION METHODS

Data were extracted from existing administrative data systems in each participating country.

STUDY DESIGN

This is a retrospective cohort study of all individuals admitted to acute care for hip fracture. Descriptive comparisons were used to examine aggregate institutional and home-based postacute care. Care trajectories were created to track sequential care settings after acute-care discharge through institutional and community-based care in three countries where detailed information allowed. Comparisons in patient characteristics, utilization, and costs were made across these trajectories and countries.

PRINCIPAL FINDINGS

Across five countries with complete LTC data, we found notable variations with Germany having the highest days of home-based services with relatively low costs, while Sweden incurred the highest overall expenditures. Comparisons of trajectories found that France had the highest use of inpatient rehabilitation. Germany was most likely to discharge hip fracture patients to home. Over 365 days, France averaged the highest number of days in institution with 104, Canada followed at 94, and Germany had just 87 days of institutional care on average.

CONCLUSION

In this comparison of LTC services following a hip fracture, we found international differences in total use of institutional and noninstitutional care, longevity, and total expenditures. There exist opportunities to organize postacute care differently to maximize independence and mitigate costs.

Blood transfusions and hip fracture mortality - A retrospective cohort study

BACKGROUND

Hip fractures are associated with serious morbidity and mortality. Low haemoglobin at presentation has been shown to be associated with increased mortality in hip fracture patients. This comorbid patient group commonly receives packed red cell blood transfusions during their hospital admission, the impact of which is less clear.

AIMS AND OBJECTIVES

We aim to assess the rate, appropriateness and impact of blood transfusions on one-year mortality in hip fracture patients. We also aim to assess the impact of patients taking anticoagulant medications at presentation on the rates of blood transfusions in this patient group.

METHODS

A retrospective cohort study of 324 consecutive hip fracture patients. Data was collected from the national hip fracture database, electronic patient records and PACS.

RESULTS

75 patients received a blood transfusion. Receiving a blood transfusion increased absolute risk of one-year mortality by 2.466 (p < 0.05). Adjusted for age, sex, comorbidities, residence prior to admission and time from presentation to surgery increased the risk of one-year mortality was 2.790 (p < 0.05).28% of patients who went on to receive a transfusion had a haemoglobin of less than 100 g/L at presentation. 94.6% of transfused patients had a pre-transfusion haemoglobin of less than 90 g/L. There was no increased risk of requiring a blood transfusion if anticoagulant medication was being taken at presentation.

CONCLUSION

Receiving a blood transfusion during an admission for hip fracture carried an increased risk of one-year mortality of almost two and a half times. With appropriate preoperative optimisation, taking an anticoagulant medication at presentation did not increase the risk of requiring a transfusion. Most blood transfusions were administered appropriately using thresholds. Just over a quarter of patients who received a transfusion had an admission haemoglobin of less than 100 g/L, showing it as a poor predictor of blood transfusion requirement during admission.

Orthogeriatric co-management for the care of older subjects with hip fracture: recommendations from an Italian intersociety consensus

BACKGROUND

Health outcomes of older subjects with hip fracture (HF) may be negatively influenced by multiple comorbidities and frailty. An integrated multidisciplinary approach (i.e. the orthogeriatric model) is, therefore, highly recommended, but its implementation in clinical practice suffers from the lack of shared management protocols and poor awareness of the problem. The present consensus document has been implemented to address these issues.

AIM

To develop evidence-based recommendations for the orthogeriatric co-management of older subjects with HF.

METHODS

A 20-member Expert Task Force of geriatricians, orthopaedics, anaesthesiologists, physiatrists, physiotherapists and general practitioners was established to develop evidence-based recommendations for the pre-, peri-, intra- and postoperative care of older in-patients (≥ 65 years) with HF. A modified Delphi approach was used to achieve consensus, and the U.S. Preventive Services Task Force system was used to rate the strength of recommendations and the quality of evidence.

RESULTS

A total of 120 recommendations were proposed, covering 32 clinical topics and concerning preoperative evaluation (11 topics), perioperative (8 topics) and intraoperative (3 topics) management, and postoperative care (10 topics).

CONCLUSION

These recommendations should ease and promote the multidisciplinary management of older subjects with HF by integrating the expertise of different specialists. By providing a convenient list of topics of interest, they might assist in identifying unmet needs and research priorities.

Low Psoas Lumbar Vertebral Index Is Associated with Mortality after Hip Fracture Surgery in Elderly Patients: A Retrospective Analysis

The psoas-to-lumbar index (PLVI) has been reported as a simple and easy way to measure central sarcopenia. However, only few studies have evaluated the association between PLVI and survival in surgical patients. This study evaluated the association between preoperative PLVI and mortality in elderly patients who underwent hip fracture surgery. We retrospectively analyzed 615 patients who underwent hip fracture surgery between January 2014 and December 2018. The median value of each PLVI was calculated according to sex, and the patients were categorized into two groups on the basis of the median value (low PLVI group vs. high PLVI group). Cox regression analysis was performed to evaluate the risk factors for 1 year and overall mortalities. The median values of PLVI were 0.62 and 0.50 in men and women, respectively. In the Cox regression analysis, low PLVI was significantly associated with higher 1 year (hazard ratio (HR): 1.87, 95% confidence interval (CI): 1.18–2.96, p = 0.008) and overall mortalities (HR: 1.51, 95% CI: 1.12–2.03, p = 0.006). Low PLVI was significantly associated with a higher mortality. Therefore, PLVI might be an independent predictor of mortality in elderly patients undergoing hip fracture surgery.

Rapid preoperative predicting tools for 1-year mortality and walking ability of Asian elderly femoral neck fracture patients who planned for hip arthroplasty

BACKGROUND

Femoral neck fractures in elderly patients typically warrant operative treatment and are related to high risks of mortality and morbidity. As early hip arthroplasties for elderly femoral neck fractures are widely accepted, rapid predicting models that allowed quantitative and individualized prognosis assessments are strongly needed as references for orthopedic surgeons during preoperative conversations.

METHODS

Data of patients aged ≥ 65 years old who underwent primary unilateral hemiarthroplasty or total hip arthroplasty due to femoral neck fracture between January 1st, 2012 and June 30th, 2019 in our center were collected. Candidate variables included demographic data, comorbidities, and routine preoperative screening tests. The main outcomes included 1-year mortality and free walking rate after hip arthroplasty. Patients were randomly divided into derivation and validation groups in the ratio of three to one. Nomograms were developed based on multivariable logistic regressions of derivation group via R language. One thousand bootstraps were used for internal validation. Those models were further tested in the validation group for external validation.

RESULTS

The final analysis was performed on 702 patients after exclusion and follow-up. All-cause 1-year mortality of the entire data set was 23.4%, while the free walking rate was 57.3%. Preoperative walking ability showed the biggest impact on predicting 1-year mortality and walking ability. Static nomograms were created from the final multivariable models, which allowed simplified graphical computations for the risks of 1-year mortality and walking ability in a certain patient. The bias-corrected C index of those nomograms for predicting 1-year mortality in the derivation group and the validation group were 0.789 and 0.768, while they were 0.807 and 0.759 for predicting postoperative walking ability. The AUC of the mortality and walking ability predicting models were 0.791 and 0.818, respectively.

CONCLUSIONS

Our models enabled rapid preoperative 1-year mortality and walking ability predictions in Asian elderly femoral neck fracture patients who planned for hip arthroplasty, with adequate predictive discrimination and calibration. Those rapid assessment models could help surgeons in making more reasonable clinical decisions and subsequently reducing the risk of potential medical dispute via quantitative and individualized prognosis assessments.

Comparison of Peripheral Nerve Block and Spinal Anesthesia in Terms of Postoperative Mortality and Walking Ability in Elderly Hip Fracture Patients - A Retrospective, Propensity-Score Matched Study

Purpose

To compare the effects of peripheral nerve block (PNB) and spinal anesthesia (SA) on one-year mortality and walking ability of elderly hip fracture patients after hip arthroplasty.

Methods

Patients ≥65 years who underwent unilateral hip arthroplasty due to femoral neck fracture, using either PNB or SA from 2014 to 2019, were included. Demographic data, comorbidities, and results of preoperative screening were retrospectively collected. Propensity score matching (PSM) was performed in a ratio of 1:1 for PNB and SA groups. The primary outcomes were 30-day, 90-day, and one-year mortality. Secondary outcomes included walking ability in the first postoperative year, major complications, length of stay, and the cost of hospitalization. Survival analysis was performed using Kaplan-Meier method.

Results

Three hundred and sixteen patients were included, of whom 200 received SA and 116 received PNB. Eighty-nine patients in each group were matched after PSM. Patients in the PNB group showed significantly lower risks of death in 30 days (2.2% vs 10.1%, P=0.029) and 90 days (3.4% vs 12.4%, P=0.026) after hip arthroplasty, when compared to the SA group. There was no significant difference in one-year mortality, walking ability, major complications, and length of stay. Higher hospitalization cost was found in the PNB group (53,828.21 CNY vs 59,278.83 CNY, P=0.024). One-year accumulated survival rate was higher in the PNB group without reaching a significant level.

Conclusion

PNB was related to lower 30- and 90-day mortality but higher hospitalization cost in elderly hip fracture patients after hip arthroplasty. However, the anesthesia types were not associated with one-year mortality, one-year walking ability, major complications, and length of stay.

Multi-Component Care Bundle in Geriatric Fracture Hip for Reducing Post-Operative Delirium

Background:

Delirium in elderly orthopaedic patients poses an enormous medical, social and financial burden to the healthcare system, and causes significant distress to patients and their caregivers. We examined whether a Multi-component Care Bundle (MCB) could reduce the incidence of post-operative delirium (POD) in fractured hip patients.

Methods:

An observational study was conducted, analyzing 154 patients (mean age ± SD, 85 ± 7.8, 68% women) admitted to Queen Mary Hospital with hip fracture. Half of the patients were cared for in the control group before MCB was introduced, which included installation of orientation aids, introduction of a Caregiver Empowerment Program, and incorporation of ultrasound-guided Fascia Iliaca Block (FIB) into the analgesia protocol.

Results:

There were fewer patients with POD in the MCB group, compared with the control group (18/76, 23.4% v 34/76, 44.2%, p = 0.006). Patients in MCB group consumed less opioid ( 4/77 v 13/77, p = 0.048), experienced less post-operative dizziness (2/77, 2.6% v 13/77, 16.9%, p = 0.003) and had a shorter median day to start walking post-operatively (day 1 [IQR 1-2] vs day 2 [IQR 2-3]; p = 0.001) than the control group. Length of stay was not affected.

Conclusion:

MCB effectively reduces POD, postoperative dizziness, opioid consumption, and days to start mobilization postoperatively.

Orthogeriatric Management: Improvements in Outcomes during Hospital Admission Due to Hip Fracture

Hip fractures are an important socio-economic problem in western countries. Over the past 60 years orthogeriatric care has improved the management of older patients admitted to hospital after suffering hip fractures. Quality of care in orthogeriatric co-management units has increased, reducing adverse events during acute admission, length of stay, both in-hospital and mid-term mortality, as well as healthcare and social costs. Nevertheless, a large number of areas of controversy regarding the clinical management of older adults admitted due to hip fracture remain to be clarified. This narrative review, centered in the last 5 years, combined the search terms "hip fracture", "geriatric assessment", "second hip fracture", "surgery", "perioperative management" and "orthogeriatric care", in order to summarise the state of the art of some questions such as the optimum analgesic protocol, the best approach for treating anemia, the surgical options recommendable for each type of fracture and the efficiency of orthogeriatric co-management and functional recovery.

Predicting 30-Day and 180-Day Mortality in Elderly Proximal Hip Fracture Patients: Evaluation of 4 Risk Prediction Scores at a Level I Trauma Center

This study evaluated the use of risk prediction models in estimating short- and mid-term mortality following proximal hip fracture in an elderly Austrian population. Data from 1101 patients who sustained a proximal hip fracture were retrospectively analyzed and applied to four models of interest: Physiological and Operative Severity Score for the enUmeration of Mortality and Morbidity (POSSUM), Charlson Comorbidity Index, Portsmouth-POSSUM and the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP^®) Risk Score. The performance of these models according to the risk prediction of short- and mid-term mortality was assessed with a receiver operating characteristic curve (ROC). The median age of participants was 83 years, and 69% were women. Six point one percent of patients were deceased by 30 days and 15.2% by 180 days postoperatively. There was no significant difference between the models; the ACS-NSQIP had the largest area under the receiver operating characteristic curve for within 30-day and 180-day mortality. Age, male gender, and hemoglobin (Hb) levels at admission <12.0 g/dL were identified as significant risk factors associated with a shorter time to death at 30 and 180 days postoperative (p < 0.001). Among the four scores, the ACS-NSQIP score could be best-suited clinically and showed the highest discriminative performance, although it was not specifically designed for the hip fracture population.

Comparison of clinical and radiological outcomes in intertrochanteric fractures treated with InterTAN nail against conventional cephalomedullary nails: a systematic review

Intertrochanteric fractures, accountable for 50% of hip fractures, can be fixed with cephalomedullary devices such as Proximal Femoral Nail Antirotation (PFNA™), Gamma3 nailing system and TRIGEN™ InterTAN™ nail (IT). IT uniquely uses two cephalocervical screws that allow for linear compression and provide additional resistance to femoral head rotation. A literature review assessing clinical outcomes of these devices was conducted, with 14 studies enrolling 3104 patients meeting the inclusion criteria. PFNA and Gamma3 had better intraoperative outcomes compared with IT; however, IT had superior implant-related outcomes of cut-out and screw migration. No difference was found between IT and PFNA or Gamma3 in Harris Hip Scores, time to union, malunion and nonunion. Further long-term studies are needed to evaluate clinical outcomes and cost–effectiveness of cephalomedullary devices.
