Impact of Preoperative Echocardiograms on In-Hospital Outcomes of Patients Undergoing Surgical Hip Fracture Repair and Their Clinical Appropriateness.

OBJECTIVES: Preoperative transthoracic echocardiograms (TTE) before hip fracture repairs are controversial. This study aimed to quantify the frequency of ordering TTE, the appropriateness of testing based on current guidelines, and the impact of TTE on in-hospital morbidity and mortality outcomes. METHODS: This retrospective chart review of adult patients admitted with hip fracture compared the length of stay (LOS), time to surgery, in-hospital mortality, and postoperative complications between TTE and non-TTE groups. TTE patients were risk stratified using the Revised Cardiac Risk Index (RCRI) to compare TTE indication according to current guidelines. RESULTS: Of the 490 patients included in this study, 15% received preoperative TTE. The median LOS of the TTE and non-TTE groups was 7.0 and 5.0 d, respectively, whereas the median time to surgery was 34 and 14 h, respectively. The odds of in-hospital mortality remained significantly higher in the TTE group after adjusting for RCRI but not when adjusted for the Charlson Comorbidity Index. Significantly more patients in the TTE groups had postoperative heart failure and up triage in the intensive care unit. Furthermore, 48% of patients with an RCRI score of 0 received preoperative TTE, with cardiac history as the most typical indication. TTE changed perioperative management in 9% of patients. CONCLUSIONS: Patients subjected to TTE before hip fracture surgery had a longer LOS and time to surgery, with higher mortality and intensive care unit up triage rates. TTE evaluations were typically conducted for inappropriate indications, which rarely made meaningful changes to patient management.

Evaluation of FRAX in patients with periprosthetic fractures following primary total hip and knee arthroplasty.

The fracture risk assessment tool (FRAX) is a tool which calculates an individual 10-year fracture risk based on epidemiological data in patients with a risk of osteporosis. The aim of this study was to evaluate the value of FRAX to estimate the risk of postoperative periprosthetic fractures (PPF) in patients following with total hip and knee arthroplasty. 167 patients (137 periprosthetic fractures in total hip arthroplasty and 30 periprosthetic fractures in total knee arthroplasty) were included in this study. Patients' data was retrieved retrospectively. In each patient the 10-year probability of a major osteoporotic fracture (MOF) and an osteoporotic hip fracture (HF) was calculated using FRAX. According to the NOGG guideline 57% of total hip arthroplasty (THA) patients and 43.3% of total knee arthroplasty (TKA) patients were in need of osteoporosis treatment, whereas only 8% and 7% received an adequate one respectively. 56% of the patients with PPF after THA and 57% of the patients with PPF after TKA reported about a previous fracture. Significant associations between the 10-year probability of a MOF and HF calculated by FRAX and PPF in THA and TKA were seen. The results of the present study show that FRAX might have the potential to estimate the PPF in patients following THA and TKA. FRAX should be calculated before and after THA or TKA in order to assess the risk and counsel patients. The data show a clear undertreatment of patients with PPF in respect to osteoporosis.

Analysis of the Effects of COVID-19 on Hip Fractures in Korea Without Lockdown: Interrupted Time Series Analysis Using a Nationwide Cohort.

BACKGROUND: The purpose of this study was to investigate the change in the incidence rate, length of hospital stay (LOS), in-hospital mortality rate, and surgical method of hip fractures during the coronavirus disease 2019 (COVID-19) pandemic in South Korea where lockdown restrictions were not implemented. METHODS: We calculated the expected values of the incidence of hip fractures, in-hospital mortality and LOS of hip fracture patients in 2020 (COVID period) based hip fracture database of the Korean National Health Insurance Review and Assessment (HIRA) during a 9-year period from 2011 to 2019 (pre-COVID period). A generalized estimating equation model with Poisson distribution and logarithmic link function was used to estimate adjusted annual percent change (PC) of incidence rate and 95% confidence intervals (CIs). Then, we compared the annual incidence, in-hospital mortality rate and LOS in 2020 with the expected values. RESULTS: The overall incidence rate of hip fracture in 2020 was not significantly different from the expected value (PC, -5%; 95% CI, -13 to 4; P = 0.280). In women, the incidence rate of hip fracture in age groups over 70 years was smaller than the predicted value (P < 0.001). The in-hospital mortality rate was not significantly different from the expected value (PC, 5%; 95% CI, -8 to 19; P = 0.461). The mean LOS was larger than the expected value by 2% (PC, 2%; 95% CI, 1 to 3; P < 0.001). In intertrochanteric fracture, the proportion of internal fixation was smaller than the predicted value by 2% (PC, -2%; 95% CI, -3 to -1; P < 0.001), and that of hemiarthroplasty was larger than the predicted value by 8% (PC, 8%; 95% CI, 4 to 14; P < 0.001). CONCLUSIONS: In 2020, the incidence rate of hip fracture did not significantly decrease, and in-hospital mortality rate did not significantly increase compared to the expected rates, which were projected based on the HIRA hip fracture data from 2011 to 2019. Only LOS increased slightly.

Fragility fracture care gap at a tertiary teaching hospital in Malaysia.

Fracture begets fracture, pharmacological treatment is needed to prevent secondary fractures. This study found that there was a fragility fracture care gap where both bone health investigations and treatment initiation rates were low. Strategies such as Fracture Liaison Service is needed to address the care gap. PURPOSE: This study aimed to investigate the clinical burden and secondary fracture prevention of fragility fractures at a tertiary teaching hospital in Malaysia. METHODS: Electronic medical records of all patients admitted with fragility fractures between 1 January 2017-31 December 2018 were reviewed. Patients < 50 years old, with non-fragility fractures, restricted access to medical records, transferred to another hospital or who passed away during admission were excluded. Descriptive statistics were used to summarise patients' characteristics, frequency of fragility fractures, and secondary fracture prevention details. Binomial logistic regression was performed to analyse predictive factors for post-fracture bone health assessments and treatment initiation. RESULTS: 1030 patients [female (767/1030, 74.5%)] presented with 1071 fractures [hip fractures (378/1071, 35.3%)]. 170/993 (17.1%) patients were initiated on anti-osteoporosis medications (AOMs) and 148/984 (15.0%) had bone mineral density (BMD) performed within 1-year post-fracture. Less than half (42.4%) of the patients remained on treatment at 1-year post-fracture. Older patients [65-74 years old: odds ratio (OR) = 2.18, 95%CI 1.05-4.52, p = 0.04; ≥ 75 years: OR = 3.06, 95%CI 1.54-6.07, p < 0.01], hip fractures (OR = 1.95, 95%CI 1.23-3.11, p < 0.01), Chinese ethnicity (OR = 1.90, 95%CI 1.07-3.35, p = 0.03),previously diagnosed with osteoporosis (OR = 2.65, 95%CI:1.32-5.31, p < 0.01) and a BMD test performed (OR = 12.48, 95%CI 8.04-19.37, p < 0.01) were found to have higher AOM initiation. Patients with past diagnosis of osteoporosis (OR = 4.45, 95%CI 2.25-8.81, p < 0.01) and initiated on AOM (OR = 11.34, 95%CI 7.57-16.97, p < 0.01) had a higher likelihood to undergo BMD testing. CONCLUSION: The AOM initiation and BMD testing rates were low. There is a need to address the fragility fracture care gap with strategies such as Fracture Liaison Service.

Optimizing post-operative imaging: a retrospective cohort study comparing two methods of lateral hip radiography after cephalomedullary nail surgery.

BACKGROUND: Currently, there is no consensus on the most appropriate technique for obtaining lateral hip radiographs after cephalomedullary nail (CMN) surgery. The aim of this study was to investigate the distribution of two commonly used postoperative lateral hip radiographic methods (classic lateral view and modified lateral view) and try to find out which one is better suited for this situation. METHODS: A retrospective analysis was conducted on 146 patients who underwent surgical fixation for extracapsular hip fractures between January 2018 and June 2022. The main outcome measured was the angle between the straight part of the CMN and the lag screw/blade on hip lateral X-rays (CMNA). The lateral hip radiographs were categorized into two groups based on different lateral hip radiographic methods. CMNA, patient age, gender, fracture classification based on the 2018 AO classification, nail length (short/long), surgical side (left/right), height, weight, BMI, preoperative waiting time, postoperative imaging interval were collected and compared between the two groups. RESULTS: The distribution trend of CMNA significantly differs between two types of hip joint lateral radiographic methods. Specifically, the classic lateral method exhibits a significantly bimodal and skewed distribution with a median (p25, p75) of -21.6° (-31.2°, -8°), whereas the modified lateral method presents a normal distribution with a mean ± SD of +7.57° ± 14.4°. The difference in the Mean Rank between the classic (47.10) and the modified (102.96) lateral methods is statistically significant (P < 0.001). CONCLUSIONS: The CMNA method is an excellent tool for studying the lateral distribution.We recommend using the modified lateral view as the preferred option for obtaining lateral hip radiographs after CMN surgery due to its superior distribution of CMNA and greater patient-friendliness.

The use of metformin, sulfonylurea compounds and insulin and the risk of hip fractures in diabetic patients: a systematic review and meta-analysis of observational studies.

BACKGROUND: Hip fracture is a major health problem that occurs more often in the elderly, especially in diabetic patients. Some studies have been conducted regarding the effect of anti- diabetic drugs on fractures. But so far, no meta-analysis study has been conducted to investigate the effect of diabetic drugs on hip fractures. Therefore, this study investigated the relationship between anti-diabetic drugs (Metformin, Sulfonylurea, and insulin) with hip fractures. METHODS: In this systematic review and meta analysis study, PubMed, Scopus, Google Scholar, and Web of Science databases were searched with specific keywords to find relevant studies. Two researchers included related studies after screening based on the title and full text. Cochran's Q and I2 tests were used to assess heterogeneity between studies. Publication bias between studies was evaluated for each drug using Egger's test. A 95% confidence interval was used for effect size significance. Overall, 49 studies, including 6,631,297 participants, were reviewed. RESULTS: The results showed that metformin significantly reduced the risk of hip fracture (HR: 0.833, 95% CI: 0.759, 0.914, P:0.001). Consumption of sulfonylurea compounds was significantly associated with an increased risk of hip fracture. (HR: 1.175, 95% CI:1.068,1.293, P:0.001), The risk of hip fracture in patients receiving insulin was significantly higher than in diabetic patients who did not receive insulin. (HR:1.366, 95% CI:1.226,1.522, P:0.001). CONCLUSION: The results of this study showed that taking metformin reduces the risk of hip fracture, and insulin and Sulfonylurea increase the risk of hip fracture.

Trends and treatments of pelvic and acetabular fractures in Taiwan: facing an aging society.

Pelvic-acetabular fractures lead to high mortality in elders and their association between different groups is not known. Our results indicate that older age with pelvic-acetabular fracture was significantly associated with mortality. This finding may help planning and allocating healthcare resources, risk stratification, and optimizing the treatment of pelvic fractures. PURPOSE: Pelvic or acetabular fractures are among main outcomes of low-energy trauma such as falls, especially in older adults. They represent approximately 3-8% of all fractures and are associated with a high mortality rate ranging from 4 to 28%. This study is aimed at comparing the incidence and trends of hip fractures and pelvic-acetabular fractures in the Taiwanese general population, gender differences in adults aged over 65 years, and mortality risk between pelvic or acetabular fractures and hip fractures and surgery trends in patients with these fractures. METHODS: A retrospective study was conducted extracting data from the National Health Insurance Research Database of patients diagnosed with hip fracture and pelvic acetabular fracture between 2000 and 2018. RESULTS: Older age with pelvic-acetabular fracture was significantly associated with increased mortality. No significant differences were found in comorbidities between the two fracture groups. Results provide clear epidemiological evidence for trends in pelvic-acetabular fractures in Taiwan and demonstrate the need for better strategies to manage these fractures and comorbidities, particularly in older adults. CONCLUSION: Findings of this study may aid in planning and allocating healthcare resources, risk stratification, and optimizing the treatment of pelvic fractures among older adults in Taiwan.

Critical Risk Factors for Opioid Demand after Pelvic and Acetabular Fracture Surgery.

The characteristics that contribute to opioid demand in pelvic and acetabular fracture surgery are not well understood. We hypothesize that fracture pattern and psychiatric comorbidities will be associated with increased opioid demand. This study evaluated perioperative opioid prescription filling in 743 patients undergoing operative fixation of pelvic and acetabular injuries. Multivariable linear and logistic regression models were used to evaluate associations between baseline factors and opioid outcomes. Patients filled prescriptions for 111.2, 89.3, and 200.3 oxycodone 5-mg pills at the 1-month preop to 90-days postop, 3-months postop to 1-year postop, and 1-month preop to 1-year postop timeframes. Operatively treated wall, transverse and two-column acetabular fractures were associated with the highest opioid demand. Drug abuse and pre-injury opioid use were the primary non-surgical drivers of opioid demand. Acetabular fractures, pre-injury opioid filling, and drug abuse were the main risk factors for increased perioperative opioid prescription filling. Level of Evidence: Level III, retrospective, prognostic cohort study. (Journal of Surgical Orthopaedic Advances 32(1):041-046, 2023).

A Barbed Proximal Femoral Nailing System for Isolated Intertrochanteric Femur Fractures: Operative Outcomes.

Intertrochanteric femur fractures are associated with high morbidity/mortality, necessitating strategies to limit time under anesthesia, blood loss, and additional trauma while achieving maximal fixation in osteopenic bone. The Orthopedic Designs North America, Inc. Talon DistalFix Femoral Nail System uses deployable barbs to maximize axial and rotational control without distal interlock screws. The purpose of this study was to evaluate perioperative features and postoperative outcomes in patients treated with the DistalFix Femoral Nailing System for isolated intertrochanteric femur fractures. Seventy-one consecutive patients underwent intramedullary fixation for isolated intertrochanteric fractures with the DistalFix system between January 2019-July 2020. Median operative time was 35 (33 - 40) minutes. Median estimated blood loss was 125 (75 - 150) cc. Median fluoroscopy time was 2.4 (2.2 - 2.9) minutes and dosage was 27.1 (18.0 - 35.2) mGy. Union occurred in 98% of patients; none experienced implant cutout, and 81.1% returned to previous mobility. The DistalFix system achieves a high rate of union and return to function while limiting operative risk factors. (Journal of Surgical Orthopaedic Advances 32(1):036-040, 2023).

Factors Associated With Hip Fracture Length of Stay Among Older Adults in a Community Hospital Setting.

INTRODUCTION: Hip fractures in geriatric populations constitute a heavy burden on the healthcare system. The study goal was to identify patient, hospital, and surgical factors associated with hospital length of stay (LOS) for geriatric patients with hip fractures requiring surgical intervention in a community hospital setting. METHODS: This was a cross-sectional retrospective chart review of geriatric hip fractures that underwent surgical fixation at a community hospital between 2017 and 2019. The scope of the surgeries was limited to cephalomedullary device fixation or hemiarthroplasty hip fracture surgeries. Sliding hip screw or total hip arthroplasty procedures and patients who died during the index hospitalization were excluded. Median tests were conducted to examine differences between the groups. Unadjusted and adjusted truncated negative binomial regression models were used to examine the factors associated with LOS. RESULTS: Bivariate analyses revealed results that the factors associated with a longer LOS were preoperative anemia (P = 0.029), blood transfusion (P = 0.022), and the number of days between admission and surgery (P = 0.001). The adjusted regression model results suggested that older patients, patients who underwent surgery more than one day after admission, current smokers, malnourished patients, patients with sepsis, and patients with a history of a thromboembolic event had statistically significant (P < 0.05) longer LOS. However, patients who live in institutions (nursing homes or assisted living) had a shorter LOS than those who live at home alone or with family (P < 0.05). DISCUSSION: Older adult patients who underwent surgery with a cephalomedullary device or hip hemiarthroplasty for a hip fracture and had preoperative anemia, postoperative blood transfusions, and increased days between admission and surgery had a longer LOS. Additional factors positively associated with a longer LOS included current smokers, malnourishment, admission with sepsis, and patients with a history of a thromboembolic event. Of interest, institutionalized patients had a shorter LOS than those living at home alone or with family.

Effect of Variation in Early Rehabilitation on Hospital Readmission After Hip Fracture.

OBJECTIVE: Provision of early rehabilitation services during acute hospitalization after a hip fracture is vital for improving patient outcomes. The purpose of this study was to examine the association between the amount of rehabilitation services received during the acute care stay and hospital readmission in older patients after a hip fracture. METHODS: Medicare claims data (2016-2017) for older adults admitted to acute hospitals for a hip fracture (n = 131,127) were used. Hospital-based rehabilitation (physical therapy, occupational therapy, or both) was categorized into tertiles by minutes per day as low (median = 17.5), middle (median = 30.0), and high (median = 48.8). The study outcome was risk-adjusted 7-day and 30-day all-cause hospital readmission. RESULTS: The median hospital stay was 5 days (interquartile range [IQR] = 4-6 days). The median rehabilitation minutes per day was 30 (IQR = 21-42.5 minutes), with 17 (IQR = 12.6-20.6 minutes) in the low tertile, 30 (IQR = 12.6-20.6 minutes) in the middle tertile, and 48.8 (IQR = 42.8-60.0 minutes) in the high tertile. Compared with high therapy minutes groups, those in the low and middle tertiles had higher odds of a 30-day readmission (low tertile: odds ratio [OR] = 1.11, 95% CI = 1.06-1.17; middle tertile: OR = 1.07, 95% CI = 1.02-1.12). In addition, patients who received low rehabilitation volume had higher odds of a 7-day readmission (OR = 1.20; 95% CI = 1.10-1.30) compared with high volume. CONCLUSION: Elderly patients with hip fractures who received less rehabilitation were at higher risk of readmission within 7 and 30 days. IMPACT: These findings confirm the need to update clinical guidelines in the provision of early rehabilitation services to improve patient outcomes during acute hospital stays for individuals with hip fracture. LAY SUMMARY: There is significant individual- and hospital-level variation in the amount of hospital-based rehabilitation delivered to older adults during hip fracture hospitalization. Higher intensity of hospital-based rehabilitation care was associated with a lower risk of hospital readmission within 7 and 30 days.

Surgical Management of Metastatic Pathologic Subtrochanteric Fractures: Treatment Modalities and Associated Outcomes.

BACKGROUND: Subtrochanteric pathological fractures (PFs) occur in approximately one-third of femur bone metastases. We seek to analyze surgical treatment strategies for subtrochanteric metastatic PFs and their revision rates. METHODS: A systematic review was performed using the PubMed and Ovid databases. Reoperations as a result of complications were analyzed according to initial treatment modality, primary tumor site, and type of revision procedure. RESULTS: We identified a total of 544 patients, 405 with PFs and 139 with impending fractures. The study population's mean age was 65.85 years with a male/female ratio of 0.9. Patients with subtrochanteric PFs who underwent an intramedullary nail (IMN) procedure (75%) presented a noninfectious revision rate of 7.2%. Patients treated with prosthesis reconstruction (21%) presented a noninfectious revision rate of 8.9% for standard endoprostheses and 2.5% for tumoral endoprostheses (p < 0.001). Revision rates because of infection were 2.2% for standard and 7.5% for tumoral endoprostheses. There were no infections within the IMN and plate/screws group (p = 0.407). Breast was the most common primary tumor site (41%) and had the highest revision rate (14.81%). Prosthetic reconstructions were the most common type of revision procedure. CONCLUSION: No consensus exists regarding the optimal surgical approach in patients with subtrochanteric PFs. IMN is a simpler, less invasive procedure, ideal for patients with a shorter survival. Tumoral prostheses may be better suited for patients with longer life expectancies. Treatment should be tailored considering revision rates, patient's life expectancy, and surgeon's expertise. LEVEL OF EVIDENCE: Level III. See Instructions for Authors for a complete description of levels of evidence.

Lower estimated glomerular filtration rate at admission is associated with a worse outcome in older patients with hip fracture who undergo surgical treatment.

BACKGROUND: We assessed the relationship of estimated glomerular filtration rate values at hospital admission on the outcome of surgically treated older adults who had suffered a hip fracture. METHODS: Prospective study that included patients > 65 years of age, surgically treated for primary hip fracture, with no pathologic or high-energy trauma aetiology admitted to a tertiary teaching hospital between 2018 and 2019. We stratified patients based on their estimated glomerular filtration rate at admission and examined its association to demographic and clinical variables, including 90-day post-discharge mortality. RESULTS: The study included 942 hip fracture patients. Lowered estimated glomerular filtration rate was significantly associated to a worsening of the functional status, higher incidence of medical postoperative complications, higher postoperative renal dysfunction, and greater number of blood transfusions. Mortality displayed a staircase pattern, increasing with decreasing estimated glomerular filtration rate. Patients with estimated glomerular filtration rate <60 had significantly higher mortality at 90 days after discharge. In-hospital mortality rate was 10.7% in hip fracture patients with chronic kidney disease who experienced a significant variation in the estimated glomerular filtration rate (>5 mL/min/1.73m2) on admission in comparison to baseline values. CONCLUSION: Older adult patients treated for hip fracture with lower glomerular filtration rate values have poorer functional status and worse prognosis. A significant clinical variation of estimated glomerular filtration rate upon hospital admission for hip fracture may be associated with increased in-hospital mortality of chronic kidney disease patients.

The effect of pre-fracture proximal femur geometry on hip fracture type in elderly patients.

This study aimed to analyze the relationship between fracture type by determining data on the geometry of the proximal femur in the pre-fracture period in patients over 65 years of age who had hip fractures as a result of low-energy trauma. A total of 127 patients who were admitted to the hospital for reasons other than hip pathology within 1 year before the occurrence of hip fracture and who had an anterior-posterior pelvic X-ray were included in the study. Measurements were made to evaluate the proximal femur geometry, neck shaft angle, central edge angle, femoral head diameter, femoral neck diameter, femoral neck length, femoral offset length, femoral neck axial length, hip axis length, and femoral shaft diameter. As a result of these measurements, analyses were performed to determine the relationship between the control group and fracture types. The mean Neck shaft angle scores were significantly higher in both fracture types than in the control group (P = .034, P = .002). The mean Femoral offset length values of both fracture types were lower than those of the control group (P = .002, P = .011, respectively). Multiple logistic regression analysis revealed that the risk of collum femoris fracture increased as the Femoral head diameter value increased. (OD = 0.21, P = .002). The geometric parameters of the proximal femur play an important role in the formation of hip fracture types. Therefore, differences in proximal femur geometry in hip fracture types should be considered, and patient-focused choices should be made regarding the surgical procedures and implants to be used during fracture fixation.

Can a Computer-based Force Feedback Hip Fracture Skills Simulator Improve Clinical Task Performance? A Cadaveric Validation Study.

BACKGROUND: This cadaveric study seeks to determine whether skills acquired on the simulator translate to improved performance of the clinical task. We hypothesized that completion of simulator training modules would improve performance of percutaneous hip pinning. METHODS: Eighteen right-handed medical students from two academic institutions were randomized: trained (n = 9) and untrained (n = 9). The trained group completed nine simulator-based modules of increasing difficulty, designed to teach techniques of placing wires in an inverted triangle construct in a valgus-impacted femoral neck fracture. The untrained group had a brief simulator introduction but did not complete the modules. Both groups received a hip fracture lecture, an explanation and pictorial reference of an inverted triangle construct, and instruction on using the wire driver. Participants then placed three 3.2 mm guidewires in cadaveric hips in an inverted triangle construct under fluoroscopy. Wire placement was evaluated with CT at 0.5 mm sections. RESULTS: The trained group significantly outperformed the untrained group in most parameters (P ≤ 0.05). CONCLUSIONS: The results suggest that a force feedback simulation platform with simulated fluoroscopic imaging using an established, increasingly difficult series of motor skills training modules has potential to improve clinical performance and might offer an important adjunct to traditional orthopaedic training.

Risk factors for perioperative acute heart failure in older hip fracture patients and establishment of a nomogram predictive model.

AIM: This study aims to explore the risk factors for perioperative acute heart failure in older patients with hip fracture and establish a nomogram prediction model. METHODS: The present study was a retrospective study. From January 2020 to December 2021, patients who underwent surgical treatment for hip fracture at the Third Hospital of Hebei Medical University were included. Heart failure was confirmed by discharge diagnosis or medical records. The samples were randomly divided into modeling and validation cohorts in a ratio of 7:3. Relevant demographic and clinic data of patients were collected. IBM SPSS Statistics 26.0 performed univariate and multivariate logistic regression analysis, to obtain the risk factors of acute heart failure. The R software was used to construct the nomogram prediction model. RESULTS: A total of 751 older patients with hip fracture were enrolled in this study, of which 138 patients (18.37%, 138/751) developed acute heart failure. Heart failure was confirmed by discharge diagnosis or medical records. Respiratory disease (odd ratio 7.68; 95% confidence interval 3.82-15.43; value of P 0.001), history of heart disease (chronic heart failure excluded) (odd ratio 2.21, 95% confidence interval 1.18-4.12; value of P 0.010), ASA ≥ 3 (odd ratio 14.46, 95% confidence interval 7.78-26.87; value of P 0.001), and preoperative waiting time ≤ 2 days (odd ratio 3.32, 95% confidence interval 1.33-8.30; value of P 0.010) were independent risk factors of perioperative acute heart failure in older patients with hip fracture. The area under the curve (AUC) of the prediction model based on these factors was calculated to be 0.877 (95% confidence interval 0.836-0.918). The sensitivity and specificity were 82.8% and 80.9%, respectively, and the fitting degree of the model was good. In the internal validation group, the AUC was 0.910, and the 95% confidence interval was 0.869-0.950. CONCLUSIONS: Several risk factors are identified for acute heart failure in older patients, based on which pragmatic nomogram prediction model is developed, facilitating detection of patients at risk early.

Association between exercise and risk of fractures in new-onset type 2 diabetes: a retrospective cohort study.

In this population-based retrospective cohort study, exercising before and after the diagnosis of type 2 diabetes was significantly associated with lower risk of fractures. This result suggested that exercising might be effective in reducing fracture risk. PURPOSE: Patients with diabetes have a significantly higher risk of fractures. We aimed to investigate the association between exercise and fracture risk in new-onset type 2 diabetes. METHODS: This retrospective cohort study using the Korean National Health Insurance Service database included 170,148 patients with new-onset type 2 diabetes who underwent two cycles of health checkup between 2009-2012 and 2011-2014. The patients were classified into four groups (non-exercising, newly exercising, previously exercising, and continuously exercising) and followed up until the date of fracture, death, or December 31, 2018. Hip fractures, vertebral fractures, and any fractures were defined using diagnostic codes. RESULTS: The proportions of non-exercising, newly exercising, previously exercising, and continuously exercising patients were 65.1%, 15.7%, 10.9%, and 8.3%, respectively. Continuously exercising patients showed the lowest risk for fractures, followed by newly exercising patients using the non-exercising group as a reference. The adjusted hazard ratios (95% confidence intervals) for hip fracture, vertebral fracture, and any fracture were 0.69 (0.50-0.94), 0.73 (0.63-0.84), and 0.90 (0.83-0.97), respectively, in the continuously exercising group and 0.76 (0.61-0.95), 0.85 (0.76-0.94), and 0.93 (0.88-0.98) in the newly exercising group. The risk was lower in patients who lost less than 5% of their body weight than in those who lost 5% or more. CONCLUSION: Exercising was associated with lower risk of fractures in newly diagnosed diabetes. However, exercise accompanied by excessive weight loss may not have a significant association with a lower risk of fractures.

A qualitative study exploring the lived experiences of patients living with mild, moderate and severe frailty, following hip fracture surgery and hospitalisation.

It is well recognised that hip fracture surgery is associated with a negative impact on short and long-term post-operative physical health and emotional well-being for patients. Furthermore, these patients are known to be frail with multiple co-morbidities. This study explores how frailty shapes the lived experiences of rehabilitation and recovery for patients who have undergone hip fracture surgery. Semi-structured interviews were conducted with sixteen participants, recently discharged from hospital following hip fracture surgery. Interpretative phenomenological analysis was applied to explore the lived experiences of frail patients and ascertain important themes. Patient experiences were captured in seven overarching themes: 1) the hospital as a place of "safety", 2) placing trust in others, 3) the slow recovery journey impeded by attitude and support, 4) maintaining autonomy and dignity whilst feeling vulnerable, 5) seeking a new normal, 6) loneliness and social isolation and 7) the ageing body. Based on our study findings, we have been able to suggest a number of opportunities to improve support for frailer patients in finding a new routine to their everyday lives, these include on-going physical and psychological support, information and education and a robust pathway for transition of care into the community. A conceptual thematic diagram is presented which helps to understand the experience and the complex needs of frail older people undergoing hip fracture surgery.
