Analysis of the effects of a delay of surgery in patients with hip fractures: outcome and causes

Early surgical care of the anticoagulated hip fracture patient within 24 hours

INTRODUCTION

Hip fractures are still associated with high morbidity and mortality. Despite international guidelines advocating for urgent surgical treatment, delays often occur, particularly for patients on long-term antithrombotic therapy. We hypothesised that urgent surgical care for the anticoagulated hip fracture patient is not associated with severe bleeding complications.

MATERIAL AND METHODS

For the period from 2015 to 2021, we retrospectively reviewed clinical records of 1142 patients with proximal femur fractures treated within 24 h of admission to our trauma centre (mean age 80.4 ± 12.4 years; 761 females, 381 males). The cohort comprised 409 femoral neck and 733 trochanteric fractures, managed with either arthroplasty (n = 297), hip-preserving techniques (n = 147), or intramedullary nailing (n = 698). Of these, 583 patients (51.1 %) were on long-term antithrombotic therapy. The primary endpoints included transfusion rate and the difference in haemoglobin (Hb) levels from pre- to postoperative. Secondary endpoints were in-patient mortality and occurrence of postoperative haematomas requiring surgical revision. A regression analysis was performed.

RESULTS

The mean time to surgery was 10.3 h, with delays observed in patients on direct oral anticoagulants (DOACs). Overall, 25.9 % (n = 296) of the patients required blood transfusions. The transfusion rate was dependent on duration of the surgery, preoperative Hb level, and anticoagulation with DOACs. Similarly, the Hb difference was found to be dependent on the duration of surgery, preoperative Hb level, and anticoagulation with DOACs. In-patient mortality was 5.3 % (n = 60). Regression analysis indicated that mortality was dependent on a high ASA classification of 4 and the time to surgery, but not on the type of antithrombotic therapy. 3.1 % of the patients needed surgical revision due to postoperative haematoma with prolonged duration of surgery and antithrombotic therapy (PAI [OR = 3.7, 95 % CI: 1.1-12.7], DOACs [OR = 3.4, 95 % CI: 1.3-8.8], and VKA [OR = 5.5, 95 % CI: 1.8-17.1], p < 0.05) as independent risk factors.

CONCLUSION

As postoperative haematoma and the need for transfusion are manageable situations, we conclude that immediate surgical treatment of hip fracture patients on long-term antithrombotic therapy within 24 h is feasible and patients may benefit.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSION

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

Is the Timing of Surgery a Sufficient Predictive Factor for Outcomes in Patients with Proximal Femur Fractures? A Systematic Review

(1) Background: Hip fractures are currently recognized as major public health problems, raising many issues in terms of both patients' quality of life and the cost associated with caring for this type of fracture. Many authors debate whether to operate as soon as possible or to postpone surgery until the patient is stable. The purpose of this review was to review the literature and obtain additional information about the moment of surgery, the time to surgery, length of hospital stay, and how all of these factors influence patient mortality and complications. (2) Methods: The systematic search was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and PICO guidelines, using the Google Scholar platform, for articles published between 2015 and 2023. Quality assessment was performed. (3) Results: After applying the inclusion criteria, 20 articles were included in the final list. Those who had surgery within 48 h had lower in-hospital and 30-day mortality rates than those who operated within 24 h. The American Society of Anesthesiologists (ASA) score is an important predictive factor for surgical delay, length of hospital stay (LOS), complications, and mortality. (4) Conclusions: Performing surgery in the first 48 h after admission is beneficial to patients after medical stabilization. Avoidance of delayed surgery will improve postoperative complications, LOS, and mortality.

"Multidisciplinary fast-track" care can significantly reduce risk of mortality among hip fracture patients at least 80 years old: a single-center retrospective study

BACKGROUND

"Multidisciplinary fast-track" (MFT) care can accelerate recovery and improve prognosis after surgery, but whether it is effective in older people after hip fracture surgery is unclear.

METHODS

We retrospectively compared one-year all-cause mortality between hip fracture patients at least 80 years old at our institution who underwent hip fracture surgery between January 2014 and December 2018 and who then received MFT or conventional care. Multivariable regression was used to assess the association between MFT care and mortality after adjustment for confounders.

RESULTS

The final analysis included 247 patients who received MFT care and 438 who received conventional orthopedic care. The MFT group showed significantly lower one-year mortality (8.9% vs. 14.4%, P = 0.037). Log-rank testing of Kaplan-Meier survival curves confirmed the survival advantage. However, the two groups did not differ significantly in rates of mortality during hospitalization or at 30 or 90 days after surgery. Regression analysis confirmed that MFT care was associated with lower risk of one-year mortality (hazard ratio [HR] 0.47, 95% confidence interval [CI] 0.281-0.788, P = 0.04), and the survival benefit was confirmed in subgroups of patients with anemia (HR 0.453, 95% CI 0.268-0.767, P = 0.003) and patients with American Society of Anesthesiologists grade III (HR 0.202, 95% CI 0.08-0.51, P = 0.001).

CONCLUSIONS

MFT care can reduce one-year mortality among hip fracture patients at least 80 years old. This finding should be verified and extended in multi-center randomized controlled trials.

Introducing a pharmacist-led transmural care program to reduce drug-related problems in orthogeriatric patients: a prospective interventional study

BACKGROUND

Orthogeriatric patients have an increased risk for complications due to underlying comorbidities, chronic drug therapy and frequent treatment changes during hospitalization. The clinical pharmacist (CP) plays a key role in transmural communication concerning polypharmacy to improve continuity of care by the general practitioner (GP) after discharge. In this study, a pharmacist-led transmural care program, tailored to orthogeriatric patients, was evaluated to reduce drug related problems (DRPs) after discharge.

METHODS

An interventional study was performed (pre-period: 1/10/2021-31/12/2021; post-period: 1/01/2022-31/03/2022). Patients (≥ 65 years) from the orthopedic department were included. The pre-group received usual care, the post-group received the pharmacist-led transmural care program. The DRP reduction rate one month after discharge was calculated. Associated factors for the DRP reduction rate were determined in a multiple linear regression analysis. The GP acceptance rate was determined for the proposed interventions, as well as their clinical impact using the Clinical, Economic and Organizational (CLEO) tool. Readmissions one month after discharge were evaluated.

RESULTS

Overall, 127 patients were included (control n = 61, intervention n = 66). The DRP reduction rate was statistically significantly higher in the intervention group compared to the control group (p < 0.001). The pharmacist's intervention was associated with an increased DRP reduction rate (+ 1.750, 95% confidence interval 1.222-2.278). In total, 141 interventions were suggested by the CP, of which 71% were accepted one month after discharge. In both periods, four patients were readmitted one month after discharge. 58% of the interventions had a clinical impact (≥ 2 C level using the CLEO-tool) according to the geriatrician and for the CP it was 45%, indicating that they had the potential to avoid patient harm.

CONCLUSIONS

The pharmacist-led transmural care program significantly reduced DRPs in geriatric patients from the orthopedic department one month after discharge. The transmural communication with GPs resulted in a high acceptance rate of the proposed interventions.

Time to surgery after proximal femur fracture in geriatric patients depends on hospital size and provided level of care: analysis of the Registry for Geriatric Trauma (ATR-DGU)

PURPOSE

Proximal femur fractures predominantly affect older patients and can mark a drastic turning point in their lives. To avoid complications and reduce mortality, expert associations recommend surgical treatment within 24-48 h after admission. Due to the high incidence, treatment is provided at a wide range of hospitals with different size and level of care, which may affect time to surgery.

METHODS

Data from 19,712 patients included from 2016 to 2019 in the Registry for Geriatric Trauma (ATR-DGU) were analyzed in terms of time to surgery, in-house mortality, mobilization on the first postoperative day, ambulation status on the 7th day after surgery, and initiation of osteoporosis therapy. Participating hospitals were grouped according to their classification as level I, II or III trauma centers. Also presence of additional injuries, intake and type of anticoagulants were considered. Linear and logistic regression analysis was performed to evaluate the influence of hospitals level of care on each item.

RESULTS

28.6% of patients were treated in level I, 37.7% in level II, and 33.7% in level III trauma centers. There was no significant difference in age, sex and ASA-score. Mean time to surgery was 19.2 h (IQR 9.0-29.8) in level I trauma centers and 16.8 h (IQR 6.5-24) in level II/III trauma centers (p < 0.001). Surgery in the first 24 h after admission was provided for 64.7% of level I and 75.0% of level II/III patients (p < 0.001). Treatment in hospitals with higher level of care and subsequent increased time to surgery showed no significant influence on in-house mortality (OR 0.90, 95%-CI 0.78-1.04), but negative effects on walking ability 7 days after surgery could be observed (OR 1.28, 95%-CI 1.18-1.38).

CONCLUSION

In hospitals of larger size and higher level of care the time to surgery for patients with a proximal femur fracture was significantly higher than in smaller hospitals. No negative effects regarding in-house mortality, but for ambulation status during in-hospital stay could be observed. As the number of these patients will constantly increase, specific treatment capacities should be established regardless of the hospitals size.

Postoperative Delirium in Patients Receiving Hip Bipolar Hemiarthroplasty for Displaced Femoral Neck Fractures: The Risk Factors and Further Clinical Outcomes

BACKGROUND

Postoperative delirium in patients who have hip fractures may lead to poor outcomes. This study aimed to determine perioperative risk factors and clinical outcomes of postoperative delirium in patients undergoing hip bipolar hemiarthroplasty for displaced femoral neck fractures.

METHODS

Among 1,353 patients who underwent hemiarthroplasty at our institution during 2013-2021, we identified 78 patients with postoperative delirium diagnosed with the confusion assessment method. The mean delirium duration was 28 hours (range: 15-520). We also included 1:2 sex- and age-matched patients who did not have postoperative delirium after the same surgery as a matching cohort for comparison. Patient comorbidities, perioperative data, delirium occurrence, and outcomes were collected for analyses.

RESULTS

A Charlson Comorbidity Index (CCI) score ≥6 (odds ratio (OR): 2.08, P = .017), nighttime surgery (OR: 3.47, p =<.001), surgical delays (OR: 1.01, P = .012), preoperative anemia (OR: 2.1, P = .012), and blood transfusions (OR: 2.47, P = .01) may increase the risk of postoperative delirium. The presentation of delirium was associated with sepsis (OR: 3.77, P = .04), longer hospital stays (P < .001), higher 1-year mortality (OR: 3.97, P = .002), and overall mortality (OR: 2.1, P = .02).

CONCLUSION

Postoperative delirium predicted poor outcomes. Our results emphasized the importance of early identification of patients at risk and optimization of the medical conditions before and after surgery.

[Result of the update of the clinical pathway for hip fracture in the elderly at a university hospital in Madrid]

BACKGROUND AND OBJECTIVES

Orthogeriatric management with clinical pathways (CP) in hip fracture (HF) has been shown to be superior to other models. We studied whether updating the CP, through prioritization of admission and surgery, improvement in the prevention and treatment of delirium, management of anticoagulants and antiplatelet agents and the use of perioperative peripheral nerve block, modifies surgical delay, stay, readmissions, mortality, suffering delirium and functional status at discharge.

MATERIAL AND METHOD

A retrospective observational study of unicenter cohorts of 468 patients with HF, 220 from 2016 (old VC) and 248 from 2019 (new VC). The variables are: intervention in the first 48hours, surgical delay (hours), stay (days), stay less than 15 days, delirium, functional loss at discharge (Barthel prefracture scale less Barthel scale at discharge), readmission at one month, and mortality at admission, month and year.

RESULTS

Median age: 87.0 [interquartile range 8.0], mostly women (76.7%). Significantly, with the new VC, there was a greater number of patients operated on in the first 48hours (27,7% vs 36,8% p=0.036), less surgical delay (72.5 [47,5-110,5] vs 64.0 [42,0-88,0] p<0.001), shorter stay (10,0 [7,0-13,0] vs 8,0 [6,0-11,0] p<0.001), greater number of discharges in 15 days (78,2% vs 91,5% p<0.001), lower delirium (54,1% vs 43,5% p=0.023). No significant changes in readmissions, functional loss at discharge, mortality at admission, 3 months or year.

CONCLUSIONS

Updating the VC brings benefits to the patient (less surgical delay, equal functional status at discharge with fewer days of admission) and benefits in management (lower admission) without modifying mortality.

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.

Risk Factors Associated With Postoperative Pulmonary Infection in Elderly Patients With Hip Fracture: A Longitudinal Study

This study aimed to conduct a longitudinal study to explore the influencing factors of pulmonary infection in elderly patients with hip fracture after surgery, to provide evidence and reference for the early identification and nursing care of patients at high risk of postoperative pulmonary infection.A secondary analysis was conducted of electronic medical record data from elderly patients with hip fractures treated in a tertiary hospital from January 1, 2020 to June 30, 2021.A total of 526 patients were included. Age ≥70 years (odd ratio [OR] 2.042, 95% confidence interval [CI] [1.516-4.022]), history of smoking (OR 2.755, 95% CI [2.009-3.175]), time from fracture to operation ≥5 days (OR 3.117, 95% CI [1.925-3.911]), American Society of Anesthesiologists grade ≥II (OR 1.254, 95% CI [1.053-1.921]), chronic obstructive pulmonary disease (OR 2.832, 95% CI [1.775-3.808]), hypoproteinemia (OR 1.395, 95% CI [1.022-1.841]), red blood cell distribution width >15% (OR 3.142, 95% CI [2.104-4.172]), intensive care unit stay (OR 2.174, 95% CI [1.083-3.718]) and duration of mechanical ventilation ≥180 minutes (OR 3.117, 95% CI [2.199-4.807]) were the independent risk factors (all p < .05).Early nursing care should be taken for patients with risk factors to reduce the pulmonary infection.

Predictors of long-term mortality after intertrochanteric fractures surgery: a 3-year retrospective study

Introduction

Intertrochanteric fractures are associated with high mortality rates; however, long-term data on survival and predictors remain scarce. Therefore, this study investigated risk factors associated with 3-year mortality in elderly patients with intertrochanteric fractures.

Methods

In a retrospective study, 156 elderly patients with intertrochanteric fractures who underwent surgery between January 2017 to January 2018 at our center were included. Association-affecting variables, such as gender, age, time from injury to surgery, hemoglobin (Hb), total lymphocyte count (TLC), albumin, malnutrition, and co-morbidities, were recorded and analyzed. Afterward, logistic regression was used to analyze the significant variables and find independent predictors for 3-year mortality.

Results

A total of 156 patients were followed up for 3 years. The 1-year, 2-year, and 3-year postoperative cumulative mortality rates were 9.6% (15/156), 16.7% (26/156), and 24.4% (38/156), respectively. Simple analyses found that age, Hb, albumin, and malnutrition were associated with 3-year mortality (p < 0.05). Multivariable analysis confirmed that advanced age (p < 0.001) and low albumin (p = 0.014) were independent risk factors for 3-year mortality.

Conclusion

Low serum albumin and advanced age were independent risk factors for long-term mortality in elderly patients with intertrochanteric fractures.
