Results of non-operative treatment following hip fracture compared to surgical intervention

Characteristics and Factors Associated With Nonoperative Management and Hospital Outcomes After Hip Fractures Among Community-Dwelling Older Adults: Retrospective Analysis

Nonoperative treatment is used at varying rates among older adults with hip fractures despite the high mortality. This retrospective analysis of 7803 patients 65 and older admitted with hip fractures is to estimate the odds of nonoperative treatment and in-hospital mortality after hip fractures among community-dwelling older adults. 13.6% underwent nonoperative treatment. Compared to the group with operative treatment, the nonoperative group had a higher in-hospital mortality rate (6.51% vs. 1.32%, p < .0001). Male sex, nondisplaced fracture, and comorbidities of acute myocardial infarction, congestive heart failure, cerebrovascular disorder, dementia, and liver disease were associated with an increased likelihood of nonoperative treatment. Nonoperative treatment, advanced age, use of osteoporosis pharmacotherapy, multiple medical comorbidities, and hospital-acquired complications were associated with increased in-hospital mortality. Specific characteristics were associated with nonoperative management and in-hospital mortality among older adults with hip fractures. Additional research is necessary to improve the care of this vulnerable population.

Impact of the SARS-CoV-2 Outbreak on the Epidemiology and Treatment Outcomes of Fractures of the Proximal Femur in Kazakhstan

The study aimed to assess the impact of isolation and quarantine on the frequency of registration and the treatment of fractures of the proximal femur in Kazakhstan in the context of the COVID-19 pandemic in 2020 (compared to the pre-pandemic period). This retrospective observational comparative study included all primary patients with injuries (the code S72) in the period 2019-2020 according to the national register.

In 2020, the number of S72 fractures was 6.6 % higher compared to 2019. In comparison with 2019, in 2020 the number of beddays of patients was reduced to 7.1±3.8 days (p≤0.001). Both in 2019 and in 2020, the number of women predominated among all patients (p ≤ 0.05). The frequency of conservative treatment in 2020 compared to 2019 was increased from 26.6% to 35.6%, while the surgical procedure for internal fixation was reduced to 34.2% in 2020. In 2020, the highest number of cases among women with S72 fractures cases were recorded in the age groups 60-74 years and 75-90 years. In 2019 in female patients (42%) with S72 cases were registered in the age group 75-90 years.

The incidence of fractures of the proximal femur did not change significantly in 2020 compared to 2019. However, the number of conservative treatment methods has increased along with the decrease in the frequency of surgical interventions. We observed the growth of the frequency of non-surgical treatment methods in 2020 that might impose the possible risks of mortality of these patients in the long term after conservative treatment.

Mortality and Related Risk Factors of Fragile Hip Fracture

Objective

To explore the mortality of patients with fragile hip fractures and assess the death‐associated risk factors.

Methods

A total of 690 patients with osteoporotic hip fractures (age, 50–103 years) that were treated from January 2010 to December 2015 were enrolled and followed‐up in this study and the clinical data were retrospectively collected. Three months, 1 year, and the total mortality were measured. Mortality‐related risk factors were assessed including age, gender, surgery, the duration from injury to operation, pulmonary infection, and the number and type of complications. The mortality of each group was compared by chi‐square test or corrected chi‐square test for univariate analysis, and the factors with statistically significant mortality difference confirmed by univariate analysis were analyzed by binary logistic multivariate analysis.

Results

The 3‐month mortality was 7.69%, the 1‐year mortality was 15.60%, and the total mortality of the follow‐up time was 24.06%. The 1‐year and total mortality during the follow‐up of the patients were higher in the >75‐year‐old group than those in the ≤75‐year‐old group (p = 0.000, respectively); were higher in the male patients than that in the female patients (p = 0.042; p = 0.017, respectively); were significantly lower in the operation group than that in the non‐operation group (p = 0.000, respectively); were significantly lower in the patients that underwent the operation in ≤5 days than the patients that underwent the operation within >5 days (p = 0.008; p = 0.000, respectively); were significantly lower in patients with >2 kinds of combined medical diseases than those with ≥2 kinds of chronic diseases (p = 0.000, respectively); were significantly lower in patients receiving anti‐osteoporosis treatment than in patients not receiving anti‐osteoporosis treatment (p = 0.000, p = 0.002, respectively). Binary logistic regression analysis showed that the independent risk factors affecting mortality included advanced age >75‐years‐old (OR = 5.653, p = 0.000), male (OR = 1.998, p = 0.001), non‐surgical treatment (OR = 9.909, p = 0.000), the number of combined medical diseases ≥2 (OR = 1.522, p = 0.042), and non‐anti‐osteoporosis treatment (OR = 1.796, p = 0.002).

Conclusion

Age, whether or not surgical treatment was performed, the number of medical diseases, and whether or not anti‐osteoporosis treatment was performed were independent risk factors for 3‐month and 1‐year mortality in patients with fragile hip fractures.

Outcomes for non-operatively managed fracture neck of femur patients: A single-institution study

BACKGROUND

The majority of neck of femur (NOF) fractures are treated operatively in the United Kingdom. The literature reports the advantages of operative management for these patients. However, whilst a subset is treated non-operatively, there is currently no clear guidance for the selection and subsequent management of these patients. This study aims to explore the incidence, demographics, inpatient stay, use of imaging and outcomes of patients who have non-operatively managed NOF fractures.

METHODS

A 6-year retrospective review (2013-2019) of all non-operatively managed NOF fractures at a tertiary teaching hospital and major trauma centre was conducted. Electronic patient records, radiographs and National Hip Fracture Database (NHFD) data were used to obtain information. We noted demographic details, fracture classification, rationale for non-operative management, mortality, clinical frailty score (CFS), use of imaging and analgesia requirements. Patients who were repatriated or transferred to other sites for specialist surgery were excluded.

RESULTS

3.2% (99/3132) of NOF fractures were managed non-operatively. The two commonest reasons for non-operative management were either 'comfortable mobilisation' (n = 44) or 'patient frailty/medically unwell' (n = 50). 74% (37/50) of the patients in whom operative risk was thought to outweigh benefit died within the 30 days of admission and 1-year mortality for this group was 92% (46/50). Of the "comfortable mobilisation" subgroup only 18% (8/44) of this patient subgroup subsequently required surgical intervention for failed non-operative management. The 30-day mortality for this cohort was 6.8% with a 1-year mortality rate of 25% (11/44).

CONCLUSION

For a select group of patients whose fractures are stable enough to allow them to mobilise comfortably, non-operative management resulted in a 25% 1-year mortality rate and average length of stay of 10.1 days. This is comparable to statistics for overall NOF fracture management in the literature according to the NHFD January 2021 report. 82% of this group of patients were successfully managed without an operation indicating that there is a place for the consideration of non-operative management in a small select subgroup of hip fracture patients with minimally displaced, stable fractures. Further analysis is necessary to assess the functional outcomes of this subgroup, as well as the potential cost implications.

Nonoperative management of hip fractures in very frail elderly patients may lead to a predictable short survival as part of advance care planning

Background and purpose - Surgical treatment is still the mainstay of care even in very frail elderly hip fracture patients. However, one may argue whether surgery is in the best interest of all patients. We elucidated mortality rates of nonoperative management (NOM) of a hip fracture after shared decision-making in a cohort of very frail elderly patients.Patients and methods - Orthogeriatric patients (age > 70 years) admitted with a hip fracture between 2011 and 2019 were included. In the presence of fragility features the motivation for surgery or NOM was supported by advance care planning (ACP) and shared decision-making through geriatric assessment. Mortality rates after NOM were assessed and also presented for the remaining surgical group for reference.Results - In 1,279 out of 3,467 patients, geriatric assessment was indicated and subsequently 1,188 (93%) had surgery versus 91 (7%) NOM. The motivation for NOM was based on patient and family preferences in only 20% of patients, medical grounds in 54%, and a combination of both in 26%. The 30-day and 1-year mortality in the frail NOM group was 87% and 99% respectively, whereas this was 7% and 28% in the surgery group. No statistical comparison between groups was performed due to profound bias by indication.Interpretation - This study provides further insight into the predictable and high short-term mortality after NOM in carefully selected very frail elderly hip fracture patients. This information may help to consider NOM as an alternative treatment option to surgery when no significant gain from surgery is anticipated.

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

This study analyzed characteristics of hip fracture patients who did not undergo surgery within 24 hours after hospitalization, as recommended by the Belgian quality standards. Reasons for delay were analyzed. Delay in surgery for hip fracture was related to the medical condition of the patients.

INTRODUCTION

To compare patients with optimal timing to patients with a delay in hip surgery, with respect to outcome (complications (postoperative) and mortality) and reasons for delay.

METHODS

A retrospective analysis of medical records compared patients operated on within 24h (Group A) to patients operated on more than 24h after admission (Group B). A follow-up period of 5 years after release or up to the time of data collection was used. Reasons for delay in relation with mortality were analyzed descriptively. Descriptive statistics were used for patient demographics and complications. Relationships causing a delayed surgery and mortality were analyzed using binary logistic regression. Additionally, a survival analysis was provided for overall mortality.

RESULTS

Respectively, 536 and 304 patients were included in Group A and B. The most prominent reason for delaying surgery was the patient not being medically fit (20.7%). Surgical delay was associated with more cardiovascular (p = 0.010), more pulmonary (p < 0.001), and less hematologic complications (p=0.037). Thirty-day mortality was higher with increasing age (p < 0.001), with hematologic (p < 0.001) or endocrine-metabolic complications (p = 0.001), and lower when no complications occurred (p = 0.004). Mortality at the end of data collection was higher for patients with delayed surgery (OR = 2.634, p < 0.001), an increased age (p = 0.006), male gender (p < 0.001), institutionalized patients (p = 0.009), pulmonary complication (p = 0.002), and having no endocrine-metabolic complications (p = 0.003). Survival analysis showed better survival for patients operated on within 24h (p < 0.001).

CONCLUSIONS

Delayed surgery for patients with hip fractures was associated with bad additional medical conditions. Survival was higher for patients operated on within 24h of admission.

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.

Factors associated with one year mortality in ill patients with proximal femoral fractures treated non operatively

INTRODUCTION

Non-operative treatment is an exceptional indication for the treatment of proximal femur fracture. The aim of the study was to analyze the mortality rate in one year and associated factors in severely ill patients submitted to non-operative treatment.

METHODS

It was included 28 patients treated from August 2014 to September 2019. Eighteen (64.3%) patients were female and 10 (35.7%) were male. The mean age was 78.7 ± 11.9 years old. The main outcome evaluated was the mortality rate in one year. It was also evaluated the correlation with gender, age, personal habits, number of comorbidities and Charlson Comorbidity Index (CCI).

RESULTS

The functional result was assessed with WOMAC score via telephone call. The mortality rate in one year was 42.8% without statistical positive correlation with any of the studied parameters. Patients with three or more comorbidities didn't have a higher mortality rate comparing to survived patients (83.3% vs 81.3%). The CCI also didn't show any correlation with high mortality (6.9 vs 7.1). The functional result of the survived patients was poor (78.2 points WOMAC).

CONCLUSION

The conclusion is that the mortality rate in one year of ill patients with hip fractures treated non-operatively is 42.8% without correlation with age, gender of number of comorbidities, and the functional result of the survived patients is poor.

Outcome of nonoperative treatment for hip fractures in elderly patients: A systematic review of recent literature

Many studies have shown that surgical management still leads to the best outcomes in elderly patients with hip fractures, with some studies showing non-inferiority of nonsurgical management as compared to surgery in fragility fractures. Evidence-based guidelines on whether to operate on these patients are lacking. A systematic literature search was conducted regarding outcomes of nonoperatively treated hip fractures in elderly patients with various comorbidities. A structured literature review of multiple databases (PubMed, Web of Science, EMBASE, and Cochrane library) referenced articles from 2000 to 2020. A total of 596 patients from 11 published studies were identified. Mean age was 83.3 years. Overall 328 (69.7%) complications occurred in 470 patients with nonsurgical treatment. Pneumonia and urinary tract infections were the most common complications which occurred in 53 (16.1%) and 46 (14.0%) patients, respectively. Hip fracture patients who were treated nonoperatively had a higher in-hospital (17.1% vs. 4.4%; p < 0.001), 30-day (31.4% vs. 10.2%; p < 0.001), and 1-year (48.5% vs. 19.9%; p < 0.001) mortality compared to a matched group of operatively treated patients (n = 1464). Of the 110 patients whose reported cause of death was nonoperative care, 44 (40%) was due to pneumonia. Patients with nonoperative treatment following hip fracture were associated with substantially higher complication and mortality compared with patients who were treated operatively. Our study will help health-care providers and caregivers to enable more informed decision-making for families and patients confronted with a hip fracture.

Mortality in Patients with Proximal Femoral Fracture During the COVID-19 Pandemic: A U.K. Hospital's Experience

BACKGROUND

Coronavirus disease 2019 (COVID-19) is a worldwide pandemic, with a case mortality ratio of approximately 6.4% at the time of writing (May 2020). Mortality increases in elderly patients with comorbidities. Patients with hip fracture have an average age of 80 years, with an estimated 2.8 comorbidities per patient. Evidence is lacking regarding the mortality rate of patients with hip fracture admitted during the COVID-19 pandemic. Our aim was to investigate the mortality rate among patients with a proximal femoral fracture who were admitted to our hospital during the COVID-19 pandemic.

METHODS

We conducted a retrospective review of all patients with a proximal femoral fracture admitted to Southend University Hospital in the U.K. from March to April 2020 (during the COVID-19 pandemic). Data collected included demographics (patient age, body mass index, sex), comorbidities, and blood test values along with COVID-19 diagnosis (based on positive microbiological sample and clinical and radiographic findings) and operative characteristics (time to operation, length of stay, American Society of Anesthesiologists [ASA] classification, Nottingham Hip Fracture Score). The primary outcome was the 30-day mortality rate for patients with a hip fracture who were COVID-19 positive or negative. Kaplan-Meier survival analysis was conducted along with Mann-Whitney U tests and Fisher exact tests.

RESULTS

Forty-one patients were included in the study, of whom 37 had an available SARS-CoV-2 (severe acute respiratory syndrome-coronavirus 2) swab test result. The overall 30-day mortality was 22%. Eleven patients tested positive for COVID-19. There was a significant difference in the mortality rate between those who tested positive and those who tested negative (54.5% versus 7.69%, respectively; Fisher exact test, p = 0.004) and between the operative patients who tested positive and the operative patients who tested negative (37.5% versus 4.34%, respectively; Fisher exact test, p = 0.043).

CONCLUSIONS

Patients with a proximal femoral fracture may be at higher risk for mortality during the COVID-19 pandemic. We noted that patients with a proximal femoral fracture who tested positive for COVID-19 had a higher 30-day mortality rate compared with those who tested negative. Additional research is required to ascertain the benefits of a reduction in time to operation.

Fewer patients undergo surgery when adding a comprehensive geriatric assessment in older patients with a hip fracture

INTRODUCTION

Geriatricians have been increasingly involved in the pre-operative process in frail elderly patients with a hip fracture which can benefit re-hospitalization, post-operative functional performance, and mortality. The objective of this study was to compare the number of older patients with hip fractures who opted for non-surgical management after the addition of pre-operative comprehensive geriatric assessment (CGA) with shared decision making by a geriatrician to usual care. Secondary objectives were: reasons for non-surgical management, duration of life, and location of death.

MATERIALS AND METHODS

A single-center, with a level 2 trauma center, retrospective study comparing care before and after introducing pre-operative CGA with shared decision making in September 2014. Patients ≥ 70 years with a hip fracture, admitted from January 2014 to September 2015, were included. The percentages of patients elected for non-surgical management and palliative care without or with CGA were compared. Differences in secondary objectives (age, sex, medical history, medication use, functional, and social status) were compared descriptively and qualitatively.

RESULTS

With pre-operative CGA significantly more patients (or representatives) elected the non-surgical management option after hip fracture (respectively, 9.1% vs 2.7%, p = 0.008). Patient characteristics were comparable. Reported reasons not to undergo surgery include aversion to be more dependent on others, and severe dementia.

CONCLUSION

The geriatrician can have an important role in decisions for non-surgical management by shared decision making in the pre-operative period in patients ≥ 70 years with a hip fracture in the emergency room.

Do we really need a surgery for hip fractures in elderly patients? Mortality rate and influencing factors

Background

Hip fractures are associated with notable mortality rates in elderly patients. The purpose of the study was to evaluate the mortality rate and influencing factors associated with mortality in the elderly patients with hip fractures.

Methods

Between October 2000 and December 2009, 807 elderly patients with hip fractures were enrolled in this study. There were 197 men and 610 women. The mean age at injuries were 78 years (range, 65–99 years). The fractures consisted of 390 femoral neck fractures and 417 intertrochanteric fractures. The mortality rate was evaluated between patients who underwent surgical and nonsurgical treatments. The influencing factors associated with mortality rate were evaluated statistically.

Results

Overall, 691 (85.6%) patients treated surgically and 116 (14.4%) patients treated nonsurgically were included. The overall mortality rates one and two years after injuries were 16.6 and 39.4%, respectively. In surgical treatment group, the mortality rate one and two years after injuries were 12.0 and 35.7%, respectively. In nonsurgical treatment group, the mortality rates were 44.0 and 61.2%, respectively (p < 0.05). No significant difference was noted between the types of fractures and the time from injury to surgery. Regardless of surgical methods, a significantly higher mortality rate was observed in patients with heart disease, chronic renal disease, dementia, and cancer, or in patients with 3 or more comorbidities.

Conclusions

In elderly patients with hip fractures, surgical treatments can decrease the mortality rate as compared with nonsurgical treatments. In addition, patients who had three or more comorbidities (heart disease, chronic renal failure, dementia, and history of cancer) are associated with a higher risk of mortality.

Nonoperative Geriatric Hip Fracture Treatment Is Associated With Increased Mortality: A Matched Cohort Study

OBJECTIVE

To report the mortality data and life expectancy of geriatric hip fracture patients who underwent nonoperative management and compare that with a matched operative cohort.

DESIGN

Retrospective cohort study.

SETTING

Level 1 trauma center.

PATIENTS

Geriatric (65 years of age and older) femoral neck or intertrochanteric fracture (OTA/AO 31A and 31B) patients.

INTERVENTION

Operative treatment with either arthroplasty, cannulated screws, sliding hip screw device, or cephalomedullary nail compared with nonoperative cohort.

MAIN OUTCOME MEASUREMENTS

In-hospital, 30-day, and 1-year mortality.

RESULTS

Two hundred thirty-one patients, comprising 154 operative and 77 nonoperative patients, were compared. There were no significant differences among age, sex, fracture location, Charlson Comorbidity Index, preinjury living location, dementia, and history of cardiac arrhythmia between the 2 cohorts. Nonoperatively managed patients were found to have a significantly higher percent in-hospital (28.6 vs. 3.9; P < 0.0001), 30-day (63.6 vs. 11.0; <0.0001), and 1-year (84.4 vs. 36.4; P < 0.0001) mortality. The mean life expectancy after a hip fracture for the nonoperative cohort was significantly shorter than the operative group (221 vs. 1024 days; P < 0.0001).

CONCLUSIONS

Nonoperatively treated hip fracture patients had an 84.4% 1-year mortality that was significantly higher than a matched operative cohort. Our results demonstrate the bleak overall prognosis for nonoperatively treated geriatric hip fractures as well as the associated reduction in mortality with surgical treatment. Our findings offer helpful information by providing updated mortality data when discussing nonoperative hip fracture management with patients and their family.

Outcome of non-surgical treatment of proximal femur fractures in the fragile elderly population

INTRODUCTION

With the aging of the population the rate of fragility hip fractures increases. While medical recommendations are for hasten surgical treatment, for some older patients burdened with severe comorbidities, this might be risky.

AIMS

To compare the outcomes of patients treated non-surgically to those of the most fragile patients treated surgically.

PATIENTS AND METHODS

A retrospective cohort study, of individuals aged ≥65 years who presented with fragility hip fractures between 01.01.2011-30.06.2016, to a primary trauma center. Patients treated surgically were stratified according to their age-adjusted Charlsons' comorbidity index (ACCI) score. Patients in the upper third of ACCI score, representing the more fragile population, were compared to patients treated non-surgically.

RESULTS

847 patients presented with fragility fractures. 94 (11%) were treated non-surgically and 753 (89%) underwent surgery. Medical reasons were the leading cause for non-surgical treatment (61.7%). Surgically-treated patients were stratified according to their ACCI and 114 patients with ACCI > 9 were chosen for comparison. While both groups were comparable in terms of age, the non-surgical treatment group had more female patients (p. = 0.026) and a smaller proportion of independent walkers (p < 0.001). The ACCI was higher for the surgical treatment group (p < 0.001). In-hospital mortality was similar (14.9% and 18.1% for the operative and non-surgical groups respectively, P. = 0.575). However, one-year mortality was significantly higher for the non-surgical group (48.2% vs. 67.0%, P. = 0.005). The rates of in-hospital complications and 1-year readmissions were similar.

CONCLUSIONS

Operative treatment for fragility hip fracture reduces long-term mortality rates even in the more fragile patients, compared to non-surgical treatment.

Factors associated with functional rehabilitation outcomes of non-operative treatment for hip fractures: a retrospective study

[Purpose] Limited data are available regarding the outcomes of non-operative treatment for hip fractures. We investigated the factors associated with functional rehabilitation outcomes in patients undergoing non-operative treatment for hip fractures. [Participants and Methods] We investigated 57 patients with hip fractures who underwent non-operative treatment. We retrospectively analyzed medical or rehabilitation outcomes and functional outcomes (assessed using the Functional Independence Measure tool). We examined the association between functional outcomes and other factors and compared the medical and rehabilitation outcomes between mobile and immobile patients at the time of discharge. [Results] Of the 57 patients investigated, 15 (26.3%) were mobile at discharge. We observed a significant association between the Functional Independence Measure subscores (Motor and Cognitive) and serum albumin levels. Serum albumin levels and the Functional Independence Measure subscores (Motor and Cognitive) were significantly higher in mobile than in immobile patients. [Conclusion] We observed that functional outcomes at discharge in patients undergoing non-operative treatment for hip fractures were associated with serum albumin ratios and the Functional Independence Measure-Cognitive score.

Operationalising a conceptual framework for a contiguous hospitalisation episode to study associations between surgical timing and death after first hip fracture: a Canadian observational study

OBJECTIVE

We describe steps to operationalise a published conceptual framework for a contiguous hospitalisation episode using acute care hospital discharge abstracts. We then quantified the degree of bias induced by a first abstract episode, which does not account for hospital transfers.

DESIGN

Retrospective observational study.

SETTING

All acute care hospitals in nine Canadian provinces.

PARTICIPANTS

We retrieved acute hospitalisation discharge abstracts for 189 448 patients aged 65 years and older admitted to acute care with hip fracture between 2003 and 2013.

PRIMARY AND SECONDARY OUTCOME MEASURES

The percentage of patients treated surgically, delayed to surgery (defined as two or more days after admission) and dying, between contiguous hospitalisation episodes and the first abstract episodes of care.

RESULTS

Using contiguous hospitalisation episodes, 91.6% underwent surgery, 35.7% were delayed two or more days after admission and 6.7% died postoperatively, whereas, using the first abstract only, these percentages were 83.7%, 32.5% and 6.5%, respectively.

CONCLUSION

We demonstrate that not accounting for hospital transfers when evaluating the association between surgical timing and death underestimates reporting of the percentage of patients treated surgically and delayed to surgery by 9%, and the percentage who die after surgery by 3%. Researchers must be aware of this potential and avoidable bias as, depending on the purpose of the study, erroneous inferences may be drawn.

Outcomes and mortality after hip fractures treated in Kazakhstan

INTRODUCTION

Patients with hip fractures are usually treated operatively in Western Europe. However, in Mid-Asia different indications are used to decide whether this patient is suitable for operative treatment and those are related to specific traditions and rules in hospital. Thus, traditions and surgeon/patient fears seem to affect treatment choices in hip fractures and subsequent outcomes. The aim of our study was to investigate patients with hip fractures and compare outcome at 1-year follow-up in the operated and nonoperated patient groups.

METHODS

All patients over 50 years old who sustained a hip fracture, between January 2014 and December 2014, were included. Patients were assessed preoperatively and at 1-year follow-up, using questionnaires from National Swedish Hip Fracture Register and quality of life (Euroqol EQ-5D).

RESULTS

Out of 398 included patients, 299 were operated on and 99 were not. 344 patients remained for our analysis before the end of 1-year follow-up. 51 patients (65%) deceased in the nonoperated group as compared to 55 (21%) in the operated group, p<0.001. Out of 27 patients in the nonoperated group hip function was evaluated at 1-year follow-up, 11 (41%) were walking independently or using 1 stick, as compared to 192 (91%) in the operated group.

CONCLUSIONS

We conclude that nonoperative treatment of hip fracture patients is associated with higher mortality and worse functional outcome as compared to those who were treated operatively. We therefore advocate operative treatment of the hip fracture in the vast majority of cases.

Implant-Related Complications and Mortality After Use of Short or Long Gamma Nail for Intertrochanteric and Subtrochanteric Fractures: A Prospective Study with Minimum 13-Year Follow-up

Background:

The purpose of this study was to evaluate the rates of implant-related complications and mortality after treatment of an intertrochanteric or subtrochanteric fracture with a short or long Gamma nail.

Methods:

Between September 1998 and August 2003, 644 patients at 2 centers treated with a long or short Gamma nail for a hip fracture were prospectively enrolled in this study. These patients were followed until they reached 1 of the study end points, which included death, a reoperation directly related to the Gamma nail, or the end date of the study.

Results:

The average age (and standard deviation) of the patients included in the study was 81.3 ± 8.6 years at the time of the operation, and 28.3% of the patients were male. The rate of implant-related complications was 9.9%. The most common complications included peri-implant fracture (4.2%), proximal lateral thigh discomfort requiring extraction of the implant (2.0%), and lag-screw cutout (1.1%). Interestingly, more than half (56%) of the 27 peri-implant fractures occurred >1.5 years after the index operation. The median time from the operation to death was 2.9 years (range, 0 to 17.1 years). The 30-day mortality rate after treatment was 9.5%. Patients with American Society of Anesthesiologists (ASA) class-3 or 4 physical status had a significantly higher risk of mortality than ASA class-1 patients.

Conclusions:

Gamma nails are effective in the treatment of intertrochanteric and subtrochanteric fractures. However, 9.8% of patients had complications requiring additional surgery. The most common serious complications include peri-implant fracture and lag-screw cutout. Several peri-implant fractures occurred long after the index procedure. Patients had a high rate of mortality (27%) after 1 year, and higher preoperative ASA class was found to be a predictor of increased risk of mortality. Therefore, clinicians must carefully consider patients’ preoperative comorbidities when counselling patients on the risks of surgery.

Magnetic resonance imaging for verifying hip fracture diagnosis why, when and how?

INTRODUCTION

Hip fractures are commonly diagnosed by plain radiography. When a patient presents with negative radiographs and high clinical suspicion of fracture, guidelines recommend proceeding with magnetic resonance imaging (MRI) to diagnose the patient. The aim of this study was to assess the use of MRI in diagnosing hip fractures following trauma to the hip and describe clinical outcome after MRI-diagnosed hip fractures. The perspective was to develop new recommendations for MRI use.

MATERIALS AND METHODS

616 patients at a university hospital fulfilled the inclusion criteria of having an MRI scan of the hip following trauma between the years of 2005 and 2014. Data was collected from the patients' medical records.

RESULTS

The annual number of MRIs increased over the ten-year period. Out of 616 MRI scans 228 (37%) showed fracture of the hip with a dominance of trochanteric fractures, 185 (30%) revealed pelvic fracture and 183 (29%) were negative. No patient with acute pelvic fracture had associated fracture of the hip. The main reason to proceed with MRI was a strong clinical suspicion of fracture in patients with negative initial radiographs. Amongst the 228 patients with fracture, 187 (82%) were treated operatively. Of patients with hip fracture, 90 (39%) patients suffered a general complication and 11 (5%) had hip complications. The complication rate of patients with fracture on MRI was compared to that of a cohort of general hip fracture patients at our hospital. No significant difference in twelve months' survival or general complications could be found, but the MRI group had a significantly lower hip complication rate.

CONCLUSION

The diagnosis set by MRI, with high share of pelvic fractures or no fracture, reflects the difficulty in differential diagnosing this group of patients. The rate of occult hip fractures was low and patients with pelvic fractures already known from X-ray did not have additional hip fractures. We found an increase in the annual number of MRIs during the 10-year-period. MRI-diagnosed hip fracture patients do not suffer more complications than the regular hip fracture patient.

Hip fractures in the elderly: operative versus nonoperative management

INTRODUCTION

Hip fractures are common in the elderly. Published studies have not shown significant differences in mortality rates between hip fracture patients who were managed nonoperatively and operatively. This retrospective study looked at 340 patients with hip fractures who were admitted to a local hospital over one year, and compared the long-term mortality between those treated operatively and nonoperatively.

METHODS

All patients with hip fractures were identified retrospectively from the hospital's hip registry. Mortality data was collected through nationwide electronic medical records and telephone interviews.

RESULTS

Overall mortality rates at one (14.4%) and two years (24.4%) were comparable to those of other studies. Hip fracture patients who were treated nonoperatively had a higher risk of mortality at both one (29.8%) and two years (45.6%) after fracture (p < 0.05). Their risk of mortality was four times higher at one year and three times higher at two years after fracture than the operative group. Patients with a higher American Society of Anesthesiologists (ASA) grade did not show an increased risk in mortality compared to patients with a lower ASA grade at both one year (p = 0.072) and two years (p = 0.360) after fracture.

CONCLUSION

Elderly patients with hip fractures should be managed surgically and counselled regarding the increased risk of mortality if treated nonoperatively.

Factors associated with mortality among elderly people hospitalized due to femoral fractures

Objective

To analyze factors associated with mortality among elderly people hospitalized in a single-center regional hospital due to femoral fractures.

Methods

This was a retrospective cohort study. Patients aged 60 years or over who were hospitalized with a diagnosis of femoral fracture (ICD S72) between 2008 and 2013 were selected through the electronic medical records.

Results

The study evaluated 195 individuals of mean age 78.5 ± 9.6 years; females predominated (68.2%). The main mechanism for falls was low-energy (87.2%). Surgery was performed on 93.3% of the patients; the mean length of hospital stay was 13.6 ± 7.5 days and the mean waiting time for the surgery was 7.7 ± 4.2 days. The prevalence of mortality was 14.4%, and this occurred mostly among older individuals (p = 0.029); patients with leukocytosis (p < 0.001); those who needed intensive care (p < 0.001); and those who did not undergo surgery (p < 0.001). The mean survival was significantly longer among patients who underwent surgery and shorter among those who needed intensive care.

Conclusion

Women predominated among the hospitalizations, and the degree of leukocytosis associated with advanced age presented a relationship with mortality, independent of the type of lesion or surgical procedure. More studies still need to be conducted in order to assess other factors associated with mortality.

Preoperative optimization and risk assessment

Because most older adults with hip fractures require urgent surgical intervention, the preoperative medical evaluation focuses on the exclusion of the small number of contraindications to surgery, and rapid optimization of patients for operative repair. Although many geriatric fracture patients have significant chronic medical comorbidities, most patients can be safely stabilized for surgery with medical and orthopedic comanagement by anticipating a small number of common physiologic responses and perioperative complications. In addition to estimating perioperative risk, the team should focus on intravascular volume restoration, pain control, and avoidance of perioperative hypotension.

Surgery for hip fracture yields societal benefits that exceed the direct medical costs

BACKGROUND

A hip fracture is a debilitating condition that consumes significant resources in the United States. Surgical treatment of hip fractures can achieve better survival and functional outcomes than nonoperative treatment, but less is known about its economic benefits.

QUESTIONS/PURPOSES

We asked: (1) Are the societal benefits of hip fracture surgery enough to offset the direct medical costs? (2) Nationally, what are the total lifetime benefits of hip fracture surgery for a cohort of patients and to whom do these benefits accrue?

METHODS

We estimated the effects of surgical treatment for displaced hip fractures through a Markov cohort analysis of patients 65 years and older. Assumptions were obtained from a systematic literature review, analysis of Medicare claims data, and clinical experts. We conducted a series sensitivity analyses to assess the effect of uncertainty in model parameters on our estimates. We compared costs for medical care, home modification, and long-term nursing home use for surgical and nonoperative treatment of hip fractures to estimate total societal savings.

RESULTS

Estimated average lifetime societal benefits per patient exceeded the direct medical costs of hip fracture surgery by USD 65,000 to USD 68,000 for displaced hip fractures. With the exception of the assumption of nursing home use, the sensitivity analyses show that surgery produces positive net societal savings with significant deviations of 50% from the base model assumptions. For an 80-year-old patient, the breakeven point for the assumption on the percent of patients with hip fractures who would require long-term nursing home use with nonoperative treatment is 37% to 39%, compared with 24% for surgical patients. Nationally, we estimate that hip fracture surgery for the cohort of patients in 2009 yields lifetime societal savings of USD 16 billion in our base model, with benefits and direct costs of USD 21 billion and USD 5 billion, respectively. For an 80-year-old, societal benefits ranged from USD 2 billion to USD 32 billion, using our range of estimates for nursing home use among nonoperatively treated patients who are immobile after the fracture.

CONCLUSIONS

Surgical treatment of hip fractures produces societal savings. Although the magnitude of these savings depends on model assumptions, the finding of societal savings is robust to a range of parameter values.

Assessing preoperative frailty utilizing validated geriatric mortality calculators and their association with postoperative hip fracture mortality risk

INTRODUCTION

End-of-life surgical care is a major concern with a significant number of operations performed within the last year of life; surgery for hip fractures is a prime example. Unfortunately, no simple objective tool exists to assess life expectancy in the postoperative period. The goal of our study was to analyze 2 simple geriatric life expectancy calculators to compare with the current Veterans Affairs Surgical Quality Improvement Program (VASQIP) postoperative 30-day mortality calculator.

METHODS

This retrospective study assessed the utility of 3 validated calculators in 47 hip fracture repairs from July 2009 to May 2011. The tools included: 30-day VASQIP mortality calculator, 6-month Minimum Data Set Mortality Risk Index-Revised (MMRI-R), and Four-Year Mortality Index. The VASQIP calculator requires chart review, Current Procedural Terminology (CPT) codes, and laboratory analysis, whereas the mortality risk indices require simple patient questioning if prospective or simple chart review if retrospective. Scoring was performed and mortality risk was compared between survivors and nonsurvivors.

RESULTS

A total of 47 hip fractures were repaired during the study period with 37 survivors and 10 nonsurvivors. In all, 7 died within 30 days, 2 died within 6 months, and 1 died greater than 6 months after surgery. The mean age (standard deviation [SD]) of all patients undergoing hip fracture repair was 73.6 (13.3) years. The VASQIP calculator mean (SD) 30-day mortality risk was 10.4% (5.4) for nonsurvivors compared to survivors 4.3% (5.5), P < .003; the MMRI-R mean (SD) mortality risk was 35.8% (15.4) for nonsurvivors compared to survivors 14.7% (9.5), P < .001; the Four-Year Mortality Index mean (SD) mortality risk was 60.9% (16.9) for nonsurvivors compared to survivors 48.9% (24.4), P < .09.

CONCLUSION

Overall, the VASQIP 30-day and MMRI-R 6-month mortality calculators showed significant differences in mortality risk between survivors versus nonsurvivors in a population with hip fracture. In contrast, the Four-Year Mortality calculator may not sufficiently discriminate operative risk. The easily obtained MMRI-R has the potential to provide information on short-term postoperative mortality risk.

Poor prognosis in elderly patients who refused surgery because of economic burden and medical problem after hip fracture

Although many studies have assessed mortality and morbidity of conservative treatment after hip fracture in elderly patients, the mortality of conservative treatment done because of economic burden is unclear. Among 451 patients diagnosed with displaced hip fracture during 3 yr, 28 patients (Group I) were enrolled as conservative treatment. Fifty-six patients matched in age, gender, ASA score, and diagnosis (Group II) who had undergone surgical treatment were used as the control group. The causal factors of non-operative treatment and mortality rate and functional recovery were evaluated according to the causal factors of patients with surgical procedure. Ten patients (36%) in Group I involved medical problems and 18 (64%) by economic burdens. The cumulative mortality rate over 3, 6, 12, and 24 months was 54%, 61%, 64%, and 82% in Group I and 9%, 11%, 14%, and 21% in Group II, respectively. At the latest follow-up, all five patients in Group I displayed a nonfunctional ambulatory state, whereas only seven of 44 patients in Group II were in a nonfunctional ambulatory state. Non-surgical treatment following hip fracture that is done because of the economic burden is associated with substantially high mortality and serious functional loss.

Prevention and clinical management of hip fractures in patients with dementia

Hip fractures and dementia increase exponentially with age, and patients who are afflicted by both conditions suffer significant morbidity and mortality. The aging of our population heightens the need to recognize the interaction of these conditions in order to improve our efforts to prevent hip fractures, provide acute care that improves outcomes, and provide secondary prevention and rehabilitation that returns patients to their previous level of functioning. Identification and treatment of vitamin D deficiency and osteoporosis and assessment and interventions to reduce falls in patients with dementia can significantly impact the incidence of first and subsequent hip fractures. Acute management of hip fractures that focuses on comanagement by orthopedic surgeons and geriatricians and uses protocol-driven geriatric-focused care has been shown to decrease mortality, length of hospitalization, readmission rates, and complications including delirium. Patients with mild-to-moderate dementia benefit from intensive geriatric rehabilitation to avoid nursing home placement. Recognizing the need to optimize primary and secondary prevention of hip fractures in patients with dementia and educating providers and families will lead to improved quality of life for patients affected by dementia and hip fractures.

Decision making and outcomes of a hospice patient hospitalized with a hip fracture

CONTEXT

Hospice patients are at risk for falls and hip fracture with little clinical information to guide clinical decision making.

OBJECTIVES

To examine whether surgery is done and survival of hip fracture surgery among persons receiving hospice services.

METHODS

This was an observational cohort study from 1999 to 2007 of Medicare hospice beneficiaries aged 75 years and older with incident hip fracture. We studied outcomes among hospice beneficiaries who did and did not have surgical fracture repair. Main outcomes included the trends in the proportion of those undergoing surgery, the site of death, and six-month survival.

RESULTS

Between 1999 and 2007, approximately 1% (n=14,400) of patients aged 75 years and older admitted with a diagnosis of their first hip fracture were receiving hospice services in the 30 days before that admission and 83.4% underwent surgery. Among patients on hospice at the time of the hip fracture, 8.8% died during the initial hospitalization and an additional two-thirds died within the first six months on hospice. The median survival from hospital admission was 25.9 days for those forgoing surgery compared with 117 days for those who had surgery, adjusted for age, race, and other covariates (P<0.001).

CONCLUSION

Despite being on hospice services, the majority underwent surgery with improved survival. Sixty-six percent of all individuals on hospice at the time of the fracture died in the first six months, with the majority returning to hospice services.

Outcomes of elderly patients with proximal femoral fractures according to positive criteria for surgical treatment

Proximal femoral fractures in elderly patients are a serious problem in the aging society. Recently, surgical indications have changed due to advancements in medical technology. The purpose of this study was to investigate the outcome of elderly patients with displaced proximal hip fractures according to our positive criteria for surgical treatment. Exclusion criteria included (1) terminal-stage malignancy; (2) a combination of an inability to walk, a severe mental disorder, and caregiver refusal of surgery; and (3) nonapproval of the anesthesiologist for surgery. The study group comprised 666 elderly patients. They were categorized into surgically and nonsurgically treated groups, and their treatment outcomes were retrospectively analyzed. The majority of patients were treated surgically (97.0% vs 3.0%). One-year survival rate was higher among surgically treated patients (82.2%-91.8%) than non-surgically treated patients (55%). The major cause of death in nonsurgically treated patients was deterioration of comorbidities (66.7%), whereas this was the cause of death in 18.9% of surgically treated patients. One-year survival rates were worse in both groups with a lower American Society of Anesthesiologists grade. The 1-year survival rate of our patients suggests that our surgical criteria offer a reasonable outcome in surgically and nonsurgically treated patients. American Society of Anesthesiologists grade and preexisting comorbidities were strongly correlated with patient outcome.

Cerebral fat emboli: a trigger of post-operative delirium

Accumulating evidence implicates cerebral fat embolism (CFE) as a causative agent in post-operative confusion (POC). CFE occurs following orthopaedic procedures including, intra-medullary (IM) nailing and total joint arthroplasty (TJA). The incidence of CFE is high (59-100% TJA) and the resulting POC is associated with higher overall complication rates. Cognitive dysfunction improves in many patients but can persist - with potentially disastrous outcomes. The pathomechanics of CFE implicate circulating lipid micro-emboli (LME) that are forced from IM depots by instrumentation/nailing. Passage to the left side of the heart is possible through intra-cardiac or arteriovenous shunts in the lung. LME are propelled to the brain where they cause disruption via ischemia or by alterations in the blood-brain-barrier - causing cerebral oedema. Prevention of CFE follows established practices for preventing FES and consideration of additional techniques to remove resident fat and reduce IM pressures. When CFE occurs supportive treatment should be established.

One-year outcome for elderly patients with displaced intracapsular fractures of the femoral neck managed non-operatively

The outcome of patients with a displaced intracapsular femoral neck fracture treated non-operatively was assessed at 1 year and compared with patients managed operatively over the same time period. Data were collected prospectively for 102 consecutive patients. 80 patients underwent hemiarthroplasty and 22 were managed non-operatively. Patients were managed non-operatively if they were felt to have an unacceptably high risk of death within the perioperative period despite medical optimisation. Non-operative management entailed active early mobilisation without bed rest or traction. Patients managed non-operatively had a greater 30-day mortality compared with operatively managed patients. Deaths were due to pre-existing medical conditions or events, which had occurred at the time of hip fracture. No patient in the non-operative treatment group developed pneumonia, pressure sores or thrombo-embolic events. Patients treated non-operatively, who survived 30 days after fracture, had a mortality rate over the following year comparable with those who had undergone surgery. At 1 year, all non-operatively managed patients were able to transfer without pain and 6 of the 11 surviving patients were able to mobilise with walking aids. At 1 year, the majority of surviving non-operatively managed patients were living in their own homes. Surgical intervention is the treatment of choice for the majority of elderly patients with a displaced intracapsular femoral neck fracture. However, in patients with life-threatening medical co-morbidity, non-operative treatment with early mobilisation can yield acceptable results.
