Clinical outcomes and hospital length of stay in 2,756 elderly patients with hip fractures: a comparison of surgical and non-surgical management

Benchmarking institutional geriatric hip fracture management: a prelude to a care quality improvement initiative

BACKGROUND

Fractures around the hip in older adults have increased in the last two decades, and the numbers are projected to rise over the next 30 years with estimates that half of them will occur in Asia. Proximal hip fractures should be operated within 48 h of injury to prevent poor outcomes. This study aims to benchmark current hip fracture care using quality improvement tools of care structure, care processes, and outcomes in a tertiary care hospital in Eastern India and determine the evidence-practice gaps and barriers to implementing the six best practices that reduce mortality and morbidity in fragility hip fractures.

METHODS

A total of 101 consecutive patients above 50 years of age with proximal femoral fractures after a trivial fall were included. Patients were divided into two groups: those operated within [Group A] and beyond [Group B] 72 h of admission. Care structure assessment included delays in admission, delay in surgery, and anesthesia risk grading. Care processes included the type of surgery performed and postoperative complications. The primary outcomes were the 30-day and 1-year mortality and the secondary outcomes included the length of stay, mobility at 6 months, return to pre-fracture independence, activity limitations, pressure sores, and readmission to the hospital.

RESULTS

Group A comprised 26 individuals, and the remaining 75 were in Group B. There were two deaths in Group A as compared to one death in Group B at 30 days; however, there were no new deaths at 1 year in Group A and 14 deaths in Group B (p = 0.187). Group B had lengthier hospital stays, poorer mobility, and higher physical and mental difficulties. No patients had re-operation on the initial fracture.

CONCLUSION

This study emphasizes the importance of early admission and fast provision of surgical fixation to reduce mortality and morbidity. Benchmarking institutional practices allows for defining the evidence-practice gaps and barriers to best practice implementation. This is an essential step to begin care quality improvement for geriatric patients with proximal femur fragility fractures.

Predictors of unplanned hospital readmission after non-cardiac surgery in Singapore: a 2-year retrospective review

INTRODUCTION

Unplanned hospital readmissions after surgery contribute significantly to healthcare costs and potential complications. Identifying predictors of readmission is inherently complex and involves an intricate interplay between medical factors, healthcare system factors and sociocultural factors. Therefore, the aim of this study was to elucidate the predictors of readmissions in an Asian surgical patient population.

METHODS

A two-year single-institution retrospective cohort study of 2744 patients was performed in a university-affiliated tertiary hospital in Singapore, including patients aged 45 and above undergoing intermediate or high-risk non-cardiac surgery. Unadjusted analysis was first performed, followed by multivariable logistic regression.

RESULTS

Two hundred forty-nine patients (9.1%) had unplanned 30-day readmissions. Significant predictors identified from multivariable analysis include: American Society of Anaesthesiologists (ASA) Classification grades 3 to 5 (adjusted OR 1.51, 95% CI 1.10-2.08, p = 0.01), obesity (adjusted OR 1.66, 95% CI 1.18-2.34, p = 0.04), asthma (OR 1.70, 95% CI 1.03-2.81, p = 0.04), renal disease (OR 2.03, 95% CI 1.41-2.92, p < 0.001), malignancy (OR 1.68, 95% CI 1.29-2.37, p < 0.001), chronic obstructive pulmonary disease (OR 2.46, 95% CI 1.19-5.11, p = 0.02), cerebrovascular disease (OR 1.73, 95% CI 1.17-2.58, p < 0.001) and anaemia (OR 1.45, 95% CI 1.07-1.96, p = 0.02).

CONCLUSION

Several significant predictors of unplanned readmissions identified in this Asian surgical population corroborate well with findings from Western studies. Further research will require future prospective studies and development of predictive risk modelling to further address and mitigate this phenomenon.

The development, incidence and treatment trends of trochanteric fractures in Germany: a cohort study

BACKGROUND

Hip fractures are a major public health problem worldwide and can lead to disability, increased mortality, and reduced quality of life. We aim to provide a nationwide epidemiological analysis of trochanteric and subtrochanteric fractures and their respective surgical treatments.

METHODS

Data were retrieved from the national database of the German Department of the Interior. ICD-10-GM and OPS data from the period of 2006 to 2020 were analysed and all patients with trochanteric and subtrochanteric fractures as their main diagnosis, who were treated in a German hospital, were included. Patients were grouped by age and gender and linear regression was performed where suitable to calculate statistically significant correlations between variables and incidences.

RESULTS

985,104 pertrochanteric fractures and 178,810 subtrochanteric fractures were reported during the analysed period. We calculated a mean incidence of 80.08 ± 6.34 for pertrochanteric and 14.53 ± 1.50 for subtrochanteric fractures per million inhabitants. In both fracture types, a distinct dependence of incidence on age can be determined. Incidence rates equally rise in both sexes through the age groups with an increase of about 288-fold from those under the age of 60 to those over the age of 90 in pertrochanteric fractures, and about 123-fold in subtrochanteric fractures. Intramedullary nailing was the most common kind of treatment for both fracture types with augmentative cerclages on the rise throughout the whole period. Plate and dynamic compression screws were decreasing in frequency over the analysed period in both fractures.

CONCLUSIONS

We provided incidence data on per- and subtrochanteric fractures and their treatment. We calculated an economic impact of approximately 1.563 billion € per year in Germany. With regards to recent literature on costs of treatment and our findings regarding the implementation and utilization of different treatment methods, we conclude that the reinforcement of nationwide prevention programs is a relevant step in lessening the economic burden. We welcome the increased utilisation of intramedullary nailing as many studies show beneficiary outcomes and cost effectiveness in most of the included fracture types.

Association between major trauma centre care and outcomes of adult patients injured by low falls in England and Wales

BACKGROUND

Disability and death due to low falls is increasing worldwide and disproportionately affects older adults. Current trauma systems were not designed to suit the needs of these patients. This study assessed the association between major trauma centre (MTC) care and outcomes in adult patients injured by low falls.

METHODS

Data were obtained from the Trauma Audit and Research Network on adult patients injured by falls from <2 m between 2017 and 2019 in England and Wales. 30-day survival, length of hospital stay and discharge destination were compared between MTCs and trauma units or local emergency hospitals (TU/LEHs) using an adjusted multiple logistic regression model.

RESULTS

127 334 patients were included, of whom 27.6% attended an MTC. The median age was 79.4 years (IQR 64.5-87.2 years), and 74.2% of patients were aged >65 years. MTC care was not associated with improved 30-day survival (adjusted OR (AOR) 0.91, 95% CI 0.87 to 0.96, p<0.001). Transferred patients had a significant impact on the results. After excluding transferred patients, MTC care was associated with greater odds of 30-day survival (AOR 1.056, 95% CI 1.001 to 1.113, p=0.044). MTC care was also associated with greater odds of 30-day survival in the most severely injured patients (AOR 1.126, 95% CI 1.04 to 1.22, p=0.002), but not in patients aged >65 years (AOR 1.038, 95% CI 0.982 to 1.097, p=0.184).

CONCLUSION

MTC care was not associated with improved survival compared with TU/LEH care in the whole cohort. Patients who were transferred had a significant impact on the results. In patients who are not transferred, MTC care is associated with greater odds of 30-day survival in the whole cohort and in the most severely injured patients. Future research must determine the optimum means of identifying patients in need of higher-level care, the components of care which improve patient outcomes, develop patient-focused outcomes which reflect the characteristics and priorities of contemporary trauma patients, and investigate the need for transfer in specific subgroups of patients.

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.

The effect of birth order on length of hospitalization for pediatric traumatic brain injury: an analysis of the 1987 Finnish birth cohort

Purpose

This study examines the relationship between birth order and length of hospitalization due to pediatric traumatic brain injury (TBI).

Methods

We prospectively followed 59,469 Finnish newborns from 1987 until age 18 years. Data on first diagnosis of TBI was recorded within the 1987 Finnish Birth Cohort (FBC). Hospitalization period was divided into two categories: 2 days or less and more than 2 days. The latter was considered in this study as longer hospitalization.

Results

Compared with first born siblings, later born siblings had an increased risk of a longer hospitalization for TBI (12.7% of fourth or higher born birth children diagnosed with TBI were hospitalized for 2 or more days, 11.3% of first born, 10.4% of third born and 9.0% of second born). Fourth or higher born children were more likely to experience a repeat TBI; 13.4% of fourth or higher born children diagnosed with TBI had 2–3 TBIs during the study period compared to 9% of third born, 7.8% of second born and 8.8% of the first born. Injuries in the traffic environment and falls were the most common contributors to pediatric TBI and occurred most frequently in the fourth or higher birth category; 29.3% of TBIs among fourth or higher birth order were due to transport accidents and 21% were due to falls.

Conclusions

This study revealed a significant increase in risk for longer hospitalization due to TBI among later born children within the same sibling group. The study provides epidemiological evidence on birth order as it relates to TBI, and its potential to help to explain some of the statistical variability in pediatric TBI hospitalization over time in this population.

Traction-bed-assisted reduction and double-plate fixation for treatment of comminuted femoral intertrochanteric fractures with coronal split

Background

A coronal comminuted femoral intertrochanteric fracture is a special type of fracture that easily leads to internal fixation failure, and the current internal fixation techniques remain controversial. This study aims to evaluate the effect of traction-bed-assisted reduction and double-plate internal fixation in the treatment of comminuted and coronally split intertrochanteric femoral fracture.

Method

Retrospective analyses of the clinical data of 83 patients diagnosed with, and treated for, comminuted and coronally split intertrochanteric femoral fracture from December 2017 to November 2019 were conducted. Among the total number of 83 patients, 40 patients received traction-bed-assisted reduction and PFNA fixation (the control group), whereas 43 patients received traction-bed-assisted reduction and double-plate internal fixation (the experimental group). The major indicators for the research analysis such as the general information of patients, perioperative data, and follow-up data of both groups were collected, sorted out, and meticulously analyzed.

Results

The time taken for traction-bed-assisted reduction and double-plate intern fixation in the experimental group was significantly shorter than that in the control group (P < .05). The post-operative Harris Hip Score (HHS) at 3 months and at the final follow-up after the surgery was significantly better in the experimental group compared with that in the control group, both of which were statistically significant (P < .05). However, there were statistically no significant differences between the two groups in terms of preoperative hemoglobin (Hb) level, amount of intraoperative total blood loss, immediate post-operative Hb level, incidence of wound infection within 14 days post-operatively, time taken to step up on the ground after surgery, HHS 2 weeks after surgery, time taken for fracture healing, and the incidence of complications (P > .05).

Conclusion

The use of a traction bed to achieve adequate reduction, followed by internal fixation using double plates, comparatively takes less time for both reduction and operation in the treatment of comminuted and coronally split intertrochanteric femoral fractures, which also restores proper hip joint movements relatively early and hence provides better hip joint functions in the long run.

Development, implementation and evaluation of an optimized cross-sectoral rehabilitation program after acute hip fracture surgery: A mixed-methods study

Fall-related hip fracture (HF) is a frequent trauma in Scandinavia with a yearly incidence of 8,000 among ≥65-year-old citizens in Denmark. The rising incidence and global predictions are alarming since a HF is a major, and potentially fatal, trauma to the citizen, requiring acute surgery, a multimodal approach and post-operative crosssectoral rehabilitation. However, continuity of the rehabilitation program is frequently interrupted in the transition between sectors, compromising optimal recovery of frail citizens. Thus, there is a need to develop and implement optimized cross-sectoral rehabilitation after HF. The purpose of this explorative study was to develop, implement and evaluate an optimized cross-sectoral rehabilitation program (OCRP) after HF surgery using validated theoretical frameworks. OCRP was developed, implemented and evaluated in one municipality using a pragmatic user-centered approach, quantitative and qualitative data collection and theoretical frameworks including the Behavior Change Wheel (BCW) and RE-AIM. Results of OCRP showed optimized rehabilitation based on motivated health professionals, high patient satisfaction and tendencies of improved levels of physical function. No re-referrals to rehabilitation were reported after OCRP. The BCW, RE-AIM and user-centered approach to program development, implementation and evaluation are useful to apply in program development and evaluation processes across sectors, professions, and medical specialties.

Association of length of hospital stay with delay to surgical fixation of hip fracture

Background:

Previous research has shown increases in length of stay (LOS), morbidity and mortality when the standard for surgical fixation of hip fracture of 48 hours is not met. However, few investigators have analyzed LOS as a primary outcome, and most used time of diagnosis as opposed to time of fracture as the reference point. We examined the effect of time to surgical fixation of hip fracture, measured from time of fracture, on length of hospital stay; the secondary outcome was average 1-year mortality.

Methods:

We conducted a retrospective cohort study of patients presenting to 1 of 2 tertiary care centres in St. John’s, Newfoundland and Labrador, Canada, with a hip fracture from Jan. 1, 2014, to Dec. 31, 2018. We analyzed 3 groups based on timing of surgical fixation after fracture: less than 24 hours (group 1), 24–48 hours (group 2) and more than 48 hours (group 3). We assessed statistical significance using 1-way analysis of variance.

Results:

Of the 692 patients included in the study, 212 (30.6%) were in group 1, 360 (52.0%) in group 2 and 120 (17.3%) in group 3. A delay to surgical fixation exceeding 48 hours was associated with a significantly longer LOS, by an average of 2.9 and 2.8 days compared to groups 1 and 2, respectively (p = 0.04); there was no significant difference in LOS between groups 1 and 2. A significant difference in average 1-year mortality was observed between groups 1 (11%) and 3 (26%) (p = 0.004), and groups 2 (13%) and 3 (p = 0.009).

Conclusion:

Surgical fixation beyond 48 hours after hip fracture resulted in significantly increased LOS and 1-year mortality. Further research should be conducted to evaluate reasons for delays to surgery and the effects of these delays on time to surgical fixation as measured from time of fracture.

Cost-Effective Analysis of Dual-Energy Computed Tomography for the Diagnosis of Occult Hip Fractures Among Older Adults

OBJECTIVE

Early and accurate diagnosis of hip fractures minimizes morbidity and mortality. Although current guidelines favor magnetic resonance imaging (MRI) for the diagnosis of occult hip fractures, a new technology called dual-energy computed tomography (DECT) seems an effective alternative. This article investigates a potentially cost-effective strategy for the diagnosis of occult hip fractures in older adults in Singapore.

METHODS

A decision tree model was developed to compare costs from a payer's perspective and outcomes in terms of quality-adjusted life-years (QALYs) of different imaging strategies for diagnosing occult hip fracture, comparing MRI with DECT supplementing single-energy computed tomography (SECT) and SECT alone. Model inputs were obtained from local sources where available. Sensitivity analyses are performed to test the robustness of the results.

RESULTS

The MRI strategy was dominated by the DECT strategy, whereas DECT supplementing SECT provided 0.30 more QALYs at an incremental cost of SGD106.41 with an incremental cost-effectiveness ratio of SGD352.52 per QALY relative to SECT alone. DECT seemed a cost-effective strategy at a willingness-to-pay threshold of SGD50 000 per QALY.

CONCLUSION

DECT supplementing SECT is a cost-effective imaging strategy to diagnose occult hip fractures among older adults in Singapore and should be included in clinical pathways to expedite timely treatment and considered for reimbursement schemes.

Effect of Nonsurgical Versus Surgical Management on Geriatric Hip Fracture Mortality of Hispanic-American Male Veterans

Introduction

The effect of surgical vs nonsurgical management on hip fracture mortality of Hispanic-American male veterans has not been rigorously studied. Hence, we examined the mortality and life expectancy effect of nonsurgical vs surgical management after hip fracture in a geriatric Hispanic-American male veterans’ population.

Material and Methods

This was a retrospective cohort study of Hispanic-American male veterans who were 65 years of age or older and suffered a femoral neck or intertrochanteric fracture from January 2008 to December 2015. Analysis between a surgical cohort (cannulated screw fixation, hemiarthroplasty, total hip arthroplasty, or cephalomedullary nail) and a non-surgical cohort was performed. In-hospital, 30-day, one-year, and two-year mortality were compared between both groups.

Results

Out of 268 patients with hip fracture, 159 (59.2%) were treated surgically and 109 (40.8%) non-surgically. The overall in-hospital (9.2% vs 1.9%, P = .009), 30-day (17.4% vs 5.0%, P = .002), one-year (48.6% vs 23.3%, P < .001), and two-year (63.3% vs 36.5%, P < .001) mortality rate was found to be higher for the nonoperative group. The average life expectancy of the nonoperative cohort was significantly shorter than those who were managed surgically (216 days vs 260 days, P < .001).

Discussion and Conclusion

This study shows a higher mortality rate and lower life expectancy in geriatric male patients who were treated nonsurgically in a Veterans Health Affair hospital facility that mostly serves Hispanic-American veterans. Our results provide an expansion to the findings of other geriatric studies on hip fracture with focus in a Hispanic-American veteran male population.

Prognostic Factors of 1-Year Postoperative Functional Outcomes of Older Patients with Intertrochanteric Fractures in Thailand: A Retrospective Cohort Study

Restoration of ambulatory status is considered a primary treatment goal for older patients with intertrochanteric fractures. Several surgical-related parameters were reported to be associated with mechanical failure without focusing on the functional outcomes. Our study examines the roles of both clinical and surgical parameters as prognostic factors on 1-year postoperative ambulatory outcomes, reaching a good functional outcome (the New Mobility Score: NMS ≥ 5) and returning to preinjury functional status at one year, of older patients with intertrochanteric fracture. Intertrochanteric fractures patients age ≥65 years who underwent surgical treatment at our institute between January 2017 and February 2020 were included. Of 209 patients included, 149 (71.3%) showed a good functional outcome at one year. The pre-injury ambulatory status (OR 52.72, 95%CI 5.19–535.77, p = 0.001), BMI <23 kg/m² (OR 3.14, 95%CI 1.21–8.13, p = 0.018), Hb ≥10 g/dL (OR 3.26, 95%CI 1.11–9.57, p = 0.031), and NMS at discharge ≥2 (OR 8.50, 95%CI 3.33–21.70, p < 0.001) were identified as independent predictors for reaching a good postoperative functional outcome. Only aged ≤80 (OR 2.34, 95%CI 1.11–4.93, p = 0.025) and NMS at discharge ≥2 (OR 6.27, 95%CI 2.75–14.32, p < 0.001) were significantly associated with an ability to return to preinjury function. To improve postoperative ambulatory status, orthopedic surgeons should focus more on modifying factors, such as maintaining the preoperative hemoglobin ≥10 g/dL and providing adequate postoperative ambulation training to maximize the patients’ capability upon discharge. While surgical parameters were not identified as predictors, they can still be used as guidance to optimize the operation quality.

Quality of Life and Functional Independence of Hip Fracture Patients: Data from a Single Center Follow-Up Study in Sri Lanka

Background

Data on the functional outcomes of hip fracture patients in Sri Lanka are limited. As this information is required for the design of long-term care plans, we assessed the physical activities (activities of daily living [ADL]) and quality of life (QoL) of hip fracture survivors in Sri Lanka.

Methods

A group of 180 consecutive patients with incident hip fractures admitted to a tertiary care center in Southern Sri Lanka were followed up for 12 months. The Sinhala versions of the Barthel Index, 36-Item Short-Form Survey, and Mini-Mental State Examination were used to assess ADL, QoL, and mental status, respectively.

Results

Of the 180 patients (149 women), 107 underwent surgery. An initial sharp decline and partial recovery of ADL and QoL were observed among patients with hip fractures. Furthermore, patients who underwent surgical treatment showed faster recovery of ADL and QoL than did patients who were managed conservatively. Similarly, patients who did not have complications during the hospital stay showed faster recovery of ADL and QoL than did patients with one or more complications.

Conclusions

Hip fractures profoundly affected both ADL and QoL, and recovery remained incomplete at 12 months post fracture. Patients who underwent surgery had a faster recovery than did patients who did not undergo surgery; similarly, patients without complications also had a faster recovery than did those with complications.

The journey of recovery after hip-facture surgery: older people's experiences of recovery through rehabilitation services involving physical activity

Purpose: This study sought to explore and describe the experiences of recovery among community-living older people undergoing rehabilitation involving physical activity following hip-fracture surgery. Methods: We conducted in-depth interviews with 5 men and 16 women (age range: 67 - 84 years). The data were analysed by means of systematic text condensation.Results: The analysis revealed the following four interrelated themes: (1) what participants bring to the recovery situation matters; (2) support through individually tailored rehabilitation services, involving physical activity, - is key to recovery following hip fracture surgery; (3) needing professional help on the journey from helplessness and vulnerability to being more confident and active; and (4) making progress and regaining function represent the essence of recovery.Conclusions: All four identified themes relate to how physical activity, as an aspect of rehabilitation services, contributes to the recovery process for patients who have experienced a hip fracture. Differences were reported with regard to the services used, and all the participants were at the mercy of what their municipalities chose to offer in terms of rehabilitation services.IMPLICATIONS FOR REHABILITATIONMunicipal healthcare services should address patients' individual needs when planning, organising and implementing rehabilitation programmes involving physical activity.Healthcare professionals need to recognise older patients' experiences of reduced physical, psychological and social functioning following hip-fracture surgery and then take those experiences into account when tailoring rehabilitation programmes.Healthcare professionals providing physical rehabilitation programmes to people who have undergone hip-fracture surgery should take into account their patients' situation and lifestyle prior to experiencing a hip fracture.Municipal healthcare services should consider using recovery as a conceptual framework in relation to rehabilitation services involving physical activity.

The incidence of severe urinary tract infection increases after hip fracture in the elderly: a nationwide cohort study

Although urinary tract infection (UTI) is a common perioperative complication among elderly patients with hip fracture, its incidence and effects are often underestimated. This study investigated the effects of severe UTI (S-UTI) on elderly patients with hip fracture and the risk factors for this condition. In this retrospective nationwide cohort study, we searched Taiwan's National Health Insurance Research Database from 2000 to 2012 for data on patients aged ≥ 50 years with hip fracture who underwent open reduction and internal fixation or hemiarthroplasty for comparison with healthy controls (i.e. individuals without hip fracture). The study and comparison cohorts were matched for age, sex, and index year at a 1:4 ratio. The incidence and hazard ratios of age, sex, and multiple comorbidities associated with S-UTI were calculated using Cox proportional hazard regression models. Among the 5774 and 23,096 patients in the study and comparison cohorts, the overall incidence of S-UTI per 100 person-years was 8.5 and 5.3, respectively. The risk of S-UTI was cumulative over time and higher in the study cohort than in the comparison cohort, particularly in those who were older, were female, or had comorbidities of cerebrovascular accident or chronic renal failure.

What factors affect length of hospital stay among trauma patients? A single-center study, Southwestern Iran

PURPOSE

Trauma is a major health concern. Length of hospital stay (LOS) has been targeted as an important metric to assess trauma care. This study aims to evaluate the risk factors that affect LOS among trauma patients in a trauma center in Southwestern Iran.

METHODS

This cross-sectional study was conducted on patients admitted to Rajaee Trauma Center, Shiraz, Iran between January 1, 2018 and December 30, 2018. The inclusion criteria were age above 15 years and having traffic accident injuries, including car, motorcycle and pedestrian injury mechanisms. The exclusion criteria were existing diseases including cardiovascular, cerebral, renal, and pulmonary diseases prior to this study, dead upon arrival or within 48 h after admission, and stay at the hospital for less than 6 h. The risk variables analyzed for prolonged LOS were age, gender, mechanism of traffic accident injury, infection during hospital stay, type of injury, injury severity score, surgery during hospitalization, and survival. Poisson regression was performed to evaluate the partial effects of each covariate on trauma hospitalization (≥3 days as longer stay).

RESULTS

This study was conducted on 14,054 patients with traffic accident injury and the mean age was (33.89 ± 15.78) years. Additionally, 74.35% of the patients were male, with male to female ratio of 2.90. The result of Poisson regression indicated that male patients, higher age, combination of thoracic injuries, onset of infected sites, and surgery patients were more susceptible to have a longer LOS. Considering the site of injury, patients with face injuries followed by those with thorax injuries had the highest means of LOS (3.74 days and 3.36 days, respectively). Simultaneous existence of surgical intervention and infection in a patient had the greatest impact on prolonged LOS.

CONCLUSION

This study identified that age, gender, mechanism of injury, infection, type of injury, survival, and ISS could lead to prolongation of LOS, but the affect can be reduced by eliminating modifiable risk factors.

Relationship between comorbidities and treatment decision-making in elderly hip fracture patients

Background

Elderly patients are at a higher risk for hip fracture. Moreover, hospitalized elderly patients with hip fracture are vulnerable to adverse outcomes including higher mortality rate and long-term disability. Treatment decision-making with respect to surgical procedure and perioperative management of these patients is typically challenging owing to the presence of multiple comorbid conditions.

Aims

The purpose of this study was to investigate the relationship between comorbidities in elderly patients with hip fracture and the treatment decision-making.

Methods

884 geriatric patients (age ≥ 60 years) with hip fracture were included. Comorbidities related to age were measured using the Charlson Co-morbidity Index (CCI) and age-adjusted CCI. The CCI of each geriatric hip fracture patient was calculated based on data retrieved from the medical records. The relationship of CCI and age-adjusted CCI with surgical procedure, time-to-surgery, length of hospital stay, and perioperative management (transfusion, anti-coagulation, and analgesia) was assessed.

Results

Mean age of patients was 78.01 ± 8.62 years. The mean CCI was 0.79 ± 0.036; the mean age-adjusted CCI was 4.15 ± 0.047. The CCI was significantly associated with time-to-surgery (P = 0.004), surgical treatment (P < 0.001), and transfusion (P = 0.023). The age-adjusted CCI was significantly associated with surgical treatment (P < 0.001), analgesia (P = 0.003) and transfusion (P < 0.001). The length of hospital stay was associated with both CCI (P = 0.041), age-adjusted CCI (P = 0.002), and hypertension (P = 0.012). Hospital expenses showed a significant association with CCI (P = 0.000), age-adjusted CCI (P = 0.029), osteoprosis (P = 0.007), and hypertension (P = 0.001).

Conclusion

In this study, comorbidities were positively associated with surgical procedure and perioperative management of elderly patients with hip fracture.

Serum miR-146a and miR-150 as Potential New Biomarkers for Hip Fracture-Induced Acute Lung Injury

Background

Acute lung injury (ALI) and subsequent pulmonary infection are the most severe and usually fatal complications for elderly hip fracture patients. It is necessary to find some biomarkers for early diagnosis and prognosis of it.

Objective

This study is aimed at examining the differential expression of miR-146a, miR-150, and cytokines (IL-6 and IL-10) between younger and elderly rats suffering from hip fracture and investigating the possible meaning of them in early diagnosis and prognosis of ALI after hip fracture.

Methods and Subjects

Elderly rats and younger rats were randomly divided into sham group and fracture group, respectively. Two fracture groups received hip fracture operations. The damage degree of ALI was evaluated by histological observation and pathological score. Cytokines were measured by ELISA; miR-146a and miR-150 were analysed by qRT-PCR.

Results

After treatment, compared with the corresponding sham groups, the pulmonary histological score, the serum miR-146a concentrations, and the cytokine (IL-6 and IL-10) levels in serum and BALF were significantly higher (the miR-150 were lower) in the fracture groups (with the exception of IL-6 of the younger fracture group at 72 h, all P < 0.05). Meanwhile, compared with the younger fracture group, the aforementioned variables were significantly higher (the miR-150 levels were lower) in the elderly fracture group (with the exception of serum IL-10 and pulmonary histological score at 8 h, all P < 0.05). The results of linear regression analysis showed that serum miR-146a and miR-150 were significantly associated with pulmonary histological score.

Conclusion

Hip fracture can result in significant systemic inflammation and ALI in the rats. Compared to the younger rats, the elderly rats suffered a more remarkable ALI after hip fracture. It may be related to the abnormal expression of miR-146a and miR-150. Serum miR-146a and miR-150 are potential biomarkers for diagnosis and prognosis of ALI after hip fracture.

Hip Fractures

Hip fractures are associated with significant morbidity and mortality and a major health problem in the United States (). Eighty percent of hip fractures are experienced by 80-year-old women. Plain radiographs usually confirm the diagnosis, but if there is a high level of suspicion of an occult hip fracture, magnetic resonance imaging or bone scan is the next step to confirm the diagnosis. Areas of the hip bone have varied bone strength and blood supply, making the femoral neck one of the most vulnerable areas for fracture. A consultation to an orthopedic surgeon will determine surgical interventions.

Presumed consent: licenses and limits inferred from the case of geriatric hip fractures

BACKGROUND

Hip fractures are common and serious injuries in the geriatric population. Obtaining informed consent for surgery in geriatric patients can be difficult due to the high prevalence of comorbid cognitive impairment. Given that virtually all patients with hip fractures eventually undergo surgery, and given that delays in surgery are associated with increased mortality, we argue that there are select instances in which it may be ethically permissible, and indeed clinically preferable, to initiate surgical treatment in cognitively impaired patients under the doctrine of presumed consent. In this paper, we examine the boundaries of the license granted by presumed consent and use the example of geriatric hip fracture to build an ethical framework for understanding the doctrine of presumed consent.

DISCUSSION

The license to act under presumed consent requires three factors: patient incapacity, clinical urgency and clarity on the correct course of action. All three can apply to geriatric hip fracture. The typical patient frequently lacks capacity. Delays in initiating surgical treatment are associated with markedly increased mortality rates. Last, there appears to be consensus that surgery is the preferred treatment. Nonetheless, because there is a window of safe delay during which treating physicians can stabilize the patient, address reversible causes of cognitive impairment and identify surrogate decision makers, presumed consent should be invoked only as a method of last resort.

CONCLUSIONS

A medical situation need not be characterized by risk of imminent and certain death for presumed consent to be relevant. Rather, there are two distinct windows that must be considered: the time interval in which action may be delayed without danger, and the time interval needed to obtain a better form of consent. Presumed consent is appropriate only when the latter exceeds the former.
