RESUMEN
BACKGROUND: One of the most dangerous side effects of joint replacement for the hip, knee, shoulder, and elbow is prosthesis joint infection (PJI). Polymerase chain reaction (PCR) has been considered a promising method for PJI diagnosis due to its short diagnostic time and high sensitivity. Although several PCR methods such as multiplex PCR and broad-range PCR are useful diagnostic methods for detecting microorganisms causing PJI, values of different PCR methods for the diagnosis of PJI remain unclear. Thus, the objective of this study was to perform a meta-analysis of different PCR methods in the diagnosis of PJI to determine their diagnostic characteristics including sensitivity and specificity. METHODS: The following data were extracted: PCR method, number of patients, sample site and type, diagnosis standard, true positive, false positive, false negative, and true negative. Pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio were calculated. Meta-regression analysis was conducted to assess heterogeneity. Subgroup analysis was also performed to assess effects of several variables on meta-analysis results. RESULTS: The current study showed that pooled sensitivity and pooled specificity were 0.70 (95% CI: 0.67 - 0.73) and 0.94 (95% CI: 0.92 - 0.95), respectively. Results of subgroup analysis indicated that sequencing method showed the lowest sensitivity (0.63, 95% CI: 0.59 - 0.67). However, after excluding studies using tissue samples directly, sequencing method showed higher sensitivity (0.83, 95% CI: 0.73 - 0.90) than other PCR methods (0.74, 95% CI: 0.69 - 0.78). CONCLUSIONS: The main significance of this study was that we attempted to classify accuracies of several PCR methods and found that sequencing with a reliable sampling method could be used as an early screening strategy for PJI. Further comparisons for PCR technologies are needed to evaluate their cost effectiveness and diagnostic procedures, not just diagnostic values, to discover the optimal one for PJI diagnosis.

OBJECTIVE: Pressure ulcer (PU) is a frequent complication of hip fractures. PUs can develop at any time after a hip fracture but most appear within 2-4 days after surgery. The purpose of this study was to investigate the association between hip fractures due to sarcopenia and the risk of PUs in patients with hip fracture. METHOD: Between March 2017 and March 2019, patients aged ≥65 years of age with hip fractures were included in this retrospective cohort study. PU risk assessment according to the Braden Scale was performed within the first few hours after arrival at hospital. Skeletal muscle mass index (SMI) and hand grip strength were evaluated for a diagnosis of sarcopenia. RESULTS: Of the 289 patients admitted to the study institution, 180 patients were finally enrolled in the study (129 females; 51 males). In male patients, as SMI increased, so too did the Braden Scale score, which was statistically significant (p=0.02). However, there was no statistically significant difference between SMIs and Braden Scale scores in female patients (p=0.304). In male patients, there was no statistically significant difference between hand grip strength and Braden Scale score (p=0.251). However, in female patients, as hand grip strength increased, so too did the Braden Scale score; this was also statistically significant (p=0.041). CONCLUSION: In this study, decreased muscle mass and muscle weakness in patients with hip fractures were associated with increased PU risk as measured by Braden Scale scores in both males and females.

BACKGROUND: The purpose of this study was to analyze differences in geometrical properties of the proximal femur and predict the occurrence of basicervical fractures through a comparative study of femoral neck and basicervical fractures in patients undergoing hip structural analysis (HSA). METHODS: All patients with hip fractures who were at least 65 years old and admitted to our hospital between March 2017 and December 2019 were eligible for this study. During the study period, 149 femur neck fractures (FNF) and basicervical fractures (intertrochanteric fractures of A31.2) were included in this study. Fifty-nine patients were included in the final analysis. Factors considered to be important confounders affecting the occurrence of basicervical hip fractures were chosen for propensity-score analysis. A logistic model with basicervical hip fracture as the outcome and age, sex, weight, spinal T-score, hip T-score, and vitamin D levels as confounders was used to estimate the propensity score. RESULTS: The cross-sectional moment of inertia (CSMI) of the intertrochanter was significantly lower in patients with basicervical hip fracture (HF) than in patients with FNF (p = 0.045). However, there was no significant differences in any other HSA variable between the two groups. Receiver operating characteristic (ROC) analysis showed that cutoff point for HSA was 100 for hip axis length (HAL) (AUC = 0.659, p < 0.001) and 5.712 for CSMI of the intertrochanter (AUC = 0.676, p < 0.001). ROC analysis showed that cutoff points of HAL, CSMI of intertrochanter, and handgrip strength were 104.8, 8.75, and 16.9, respectively (AUC = 0.726, p < 0.001). CONCLUSIONS: Proximal femoral geometric analysis using HSA is a useful method for predicting the type of hip fracture. Additionally, a lower CSMI, a shorter HAL, and a lower grip strength are major predictors of basicervical fractures.

BACKGROUND: This nationwide study aimed to investigate the blood transfusion status of elderly hip fracture patients and to examine the effect of packed red blood cell transfusion on all-cause mortality. METHODS: From the Korean National Health Insurance Service-Senior cohort consisting of 588,147 participants aged over 60 years in 2002, a total of 14,744 new-onset hip fracture patients aged 65-99 years were followed up for 11 years. The adjusted hazard ratios (aHRs), risk ratios, and their 95% confidence intervals were estimated by the Cox proportional hazard model and Poisson regression model. RESULTS: There were 10,973 patients (74.42%) in the transfusion group and 3,771 (25.58%) patients in the non-transfusion group. The mean volume of blood transfusion was 1,164.51 mL (± 865.25; median, 800 mL; interquartile range, 640-1,440). In the multivariable-adjusted Cox proportional hazard model, the transfusion group had 1.34-fold more risk of all-cause mortality than the non-transfusion group (aHR, 1.34; 95% confidence interval [CI], 1.26-1.42). In the multivariate-adjusted Poisson regression model, hip fracture patients in the transfusion group were 1.43 (adjusted risk ratio [aRR], 1.43; 95% CI, 1.09-1.87; P = 0.009) folds more likely to die within 30 days than those in the non-transfusion group. The mortality risk was highest at 90 days (aRR, 1.64; 95% CI, 1.40-1.93; P < 0.001) and slightly decreased at 180 days (aRR, 1.58; 95% CI, 1.40-1.79; P < 0.001) and 1 year (aRR, 1.43; 95% CI, 1.31-1.58; P < 0.001). CONCLUSION: In this nationwide representative cohort study, blood transfusion was performed in 75% of hip fracture patients. Even after adjusting for comorbidity and anticoagulant use, the postoperative results (hospitalization, mortality) of the transfusion group did not show significantly worse results than the non-transfusion group. Therefore, adequate patient blood management can only improve the patient's outcome after hip fracture surgery.

BACKGROUND: We performed a proportion meta-analysis of currently available data to determine the prevalence of ceramic fracture for each generation. METHODS: A total of 10,571 total hip arthroplasties from 45 studies were included. Proportion meta-analysis with a random-effects model was performed to estimate the prevalence of ceramic fracture. To determine whether the ceramic fractures have a fatigue nature and a risk or latent period for the development, postoperative time lapse, patient age, and body mass index were related with ceramic fracture by metaregression analysis. RESULTS: As of postoperative 2.0 to 18.8 years, the rate of ceramic fracture was 0.5% (95% CI, 0.3%-0.8%) in the forte group and 0.2% (95% CI, 0.1%-0.4%) in the delta group (P = .059). The ceramic fracture rate for each component was 0.2% (95% CI, 0.1%-0.3%) for the forte head, 0.1% (95% CI, 0.0%-0.2%) for the delta head (P = .210), 0.2% (95% CI, 0.1%-0.3%) for the forte liner, and 0.2% (95% CI, 0.1%-0.4%) for the delta liner (P = .305). The rate of ceramic fracture per 1000 patient-years was 0.9 (95% CI, 0.5-0.13) in the forte group and 0.5 (95% CI, 0.2-0.8) in the delta group (P = .072). In metaregression analysis, no significant associations were found between prevalence of ceramic fracture and postoperative time lapse, patient age, or body mass index. CONCLUSIONS: The rate of ceramic fracture was 0.9/1000 patient-year in the forte group and 0.5/1000 patient-year in the delta group. The results of this study provide baseline data for further studies validating ceramic bearings. LEVEL OF EVIDENCE: Level I, meta-analysis.

BACKGROUND: Comparative studies of total hip arthroplasty using the direct anterior approach (DAA) compared with the anterolateral approach (ALA) by gait analysis compared the results of the two groups, the damage to the abductor muscle, with objective and detailed kinematic as well as kinetic data of actual gait. The purpose of this systematic review was to analyze the differences in gait such as time-dependent parameters, kinetics, and kinematics after THA using the DAA compared with ALA. METHODS: PubMed Central, OVID Medline, Cochrane Collaboration Library, Web of Science, EMBASE and AHRQ carried out a comprehensive search for all relevant randomized controlled trials and comparative studies, up to December 2018. Based on the following criteria, studies were selected: 1) study design: randomized controlled trials or non-randomized comparative studies; 2) study population: patients with primary osteoarthritis or avascular necrosis; 3) intervention: total hip arthroplasty by DAA or ALA; 4) Kinetic and kinematic data after gait analysis in the plains during postoperative follow-up. RESULTS: Of the 148 studies, 7 randomized controlled trials and 5 comparative studies were finally included in this systematic review. The peak hip flexion within 3 months after surgery was described in two studies and was significantly higher in the DAA group. (OR = 1.90; 95% CI [1.67,2.13]; P < 0.01, Z = 16.18). The gait speed within 3 months after surgery was reported in 3 studies and was significantly higher in the DAA group than in the ALA group. (SMD = 0.17; 95% CI [0.12,0.22]; P < 0.01, Z = 6.62) There was no difference between the two groups in stride length, step length, and hip range of motion in sagittal plane. CONCLUSIONS: In this meta-analysis, gait speed and peak hip flexion within 3 months after surgery were significantly higher in the DAA group than in the ALA group. Despite a few significant differences between two approaches, determining whether the reported differences in terms of postoperative gait values are clinically meaningful remains a substantial challenge.

BACKGROUND: Because acute cholecystitis in elderly hip fracture is not easily distinguishable from other gastrointestinal symptoms and involves atypical clinical behaviors, it may not be diagnosed in the early stage. However, the exact incidences could not be reported. We utilized data from a nationwide claims database and attempted to assess the incidence of acute cholecystitis in elderly hip fracture patients and how cholecystitis affects mortality rates after hip fracture. METHODS: Study subjects were from the Korean National Health Insurance Service-Senior cohort. From a population of approximately 5.5 million Korean enrollees > 60 years of age in 2002, a total of 588,147 participants were randomly selected using 10% simple random sampling. The subjects included in this study were those who were over 65 years old and underwent surgery for hip fractures. RESULTS: A total of 15,210 patients were enrolled in the cohort as hip fracture patients. There were 7,888 cases (51.9%) of femoral neck fracture and 7,443 (48.9%) cases of hemiarthroplasty. Thirty-six patients developed acute cholecystitis within 30 days after the index date (30-day cumulative incidence, 0.24%). Four of the 36 acute cholecystitis patients (11.1%) died within 30 days versus 2.92% of patients without acute cholecystitis. In the multivariate-adjusted Poisson regression model, hip fracture patients with incident acute cholecystitis were 4.35 (adjusted risk ratio 4.35; 95% confidence interval, 1.66-11.37; P = 0.003) times more likely to die within 30 days than those without acute cholecystitis. CONCLUSION: Incidence of acute cholecystitis in elderly patients after hip fracture within 30 days after the index date was 0.24%. Acute cholecystitis in elderly hip fracture patients dramatically increases the 30-day mortality rate by 4.35-fold. Therefore, early disease detection and management are crucial for patients.

INTRODUCTION: When locking intramedullary nails, inserting the distal interlocking screw accurately and quickly with less radiation exposure is very important. The purpose of this randomized control study was to compare radiation exposure and accuracy of distal locking screws between free-hand fluoroscopic guidance and the use of a distal targeting system (DTS). MATERIALS AND METHODS: Inclusion criteria of this study were patients older than 60 years who need an intramedullary nailing due to unstable intertrochanteric and subtrochanteric fracture. The primary outcome was the attempt numbers of image intensifier during the insertion of distal locking screws. Secondary outcomes were operative time and angles between distal locking screws and nail. RESULTS: A total of 36 patients participated in the study. Eighteen patients using free-hand fluoroscopic guidance were assigned to Group I while 18 patients using DTS were assigned to Group II. The number of attempts of image intensifier during distal screw insertion (57.3 ± 31.42 vs. 11.5 ± 7.41, p < 0.001), ratio of attempt number for distal screws to the total attempts (0.33 ± 0.21 vs. 0.12 ± 0.08, p = 0.001), the number of hand exposure to image intensifier directly (75.0 ± 29.55 vs. 13.5 ± 19.07, p < 0.001), and the time of radiation exposure during distal screws insertion (42.57 ± 2.42 s vs. 12.72 ± 8.10 s, p < 0.001) were significantly lower in Group II compared to those in Group I. And, operation time (96.3 min ± 18.94 vs. 76.1 min ± 14.10, p < 0.001) was also statistically significantly lower in Group II. Both distal locking screws were significantly closer to perpendicular direction to the nail in Group II. CONCLUSION: The attempt number of image intensifier during the insertion of two distal locking screws was significantly reduced with DTS compared with that with free hand fluoroscopic guidance. Angle between distal locking screws and nail was also more accurate using DTS.

BACKGROUND: In the early days when delta ceramics were developed, there was a period of using delta ceramic liner and alumina ceramic head. Therefore, the purpose of this study is to investigate the clinical and radiological outcomes of total hip arthroplasty using delta ceramic liner on alumina ceramic head after a minimum of 10 years of follow-up and to evaluate problems of early delta ceramic liner. METHODS: Alumina on delta cementless total hip arthroplasty was performed in 92 hips (85 patients) from August 2005 to March 2007 at our hospital. Bilateral total hip arthroplasty were performed in 7 patients, 30 patients on the left side and 48 patients on the right side. Preoperative diagnosis was osteonecrosis of the femoral head in 34 hips (37%), degenerative arthritis in 31 hips (33.7%), femur neck fracture in 21 hips (22.8%), and rheumatoid arthritis in 6 hips (6.5%). All surgeries were carried out with anterolateral approach. For the clinical evaluation, Harris hip score (HHS), pain, and range of motion were assessed. Radiographs were reviewed by the authors to search for any signs of osteolysis, loosening of implants, and heterotopic ossification. RESULTS: HHS was compared between preoperative and final follow-ups. The mean HHS improved from preoperative 58.3 points (range 27-76) to 92.7 points (range 78-98) on the final follow-up (P = .02). The mean range of hip motion at the final follow-up was flexion 116.9°, adduction 23.8°, abduction 34.6°, internal rotation 16.3°, and external rotation 39.2°. As for the postoperative pain, 1 patient complained of inguinal pain and 4 patients complained of thigh pain. Because of trauma, 3 cases of dislocation were observed in all cases. There are 3 cases with dislocation and 2 cases were treated with conservative treatment without recurrence, but 1 case was required for surgical treatment due to eccentric rim wear of delta liner. The aseptic loosening of acetabular cup and femoral stem was each 1 hip. CONCLUSION: Alumina head-on-delta liner cementless THA, using a large femoral head 32-36 mm in diameter, demonstrated satisfactory clinical and radiological results in the minimum 10 years of follow-up. Eccentric rim wear can occur even in delta ceramic liners that are known to have high strength, and this can lead to dislocation which can, in turn, increase the possibility of linear fracture.

INTRODUCTION: The purpose of this study was to investigate the reasons for delayed surgery in patients with proximal hip fracture and to compare differences in mortality between delayed surgery cases and non-delayed surgery cases. In addition, we evaluated causal factors for delayed surgery that affected differences in mortality. METHODS: From 2003 to 2013, 1290 patients (1290 hips) with unilateral femoral neck or intertrochanteric fractures who underwent surgery were categorized into Group Ia (402 patients, early surgery group) and Group Ib (888 patients, delayed surgery group). The delayed surgery group was categorized as Group IIa (270 patients, pre-hospital delay group) and Group IIb (618 patients, post-hospital delay group). Among 618 patients with post-hospital delay, 165 patients in Group IIIa were defined as delayed surgery cases due to patient factors, and 453 patients in Group IIIB were defined as delayed surgery cases due to hospital factors. Early and late mortality was compared between each group. RESULTS: Of 1290 patients, 888 patients underwent delayed surgery (mean 7.5 days, range 3-167 days) after hip fracture. The cumulative mortality rate at 30, 60 days, 3, and 12 months was 0.7, 2.0, 3.0, and 9.5% in Group Ia, respectively, and 2.4, 4.5, 5.2, and 14.5% in Group Ib, respectively (p = 0.047, p = 0.027, p = 0.078, and p = 0.012, respectively). Of 618 patients with post-hospital surgery delay, the cumulative mortality rate at 30 days and 12 months was 4.8 and 21.2% in Group IIIa, respectively, and 1.8, and 12.6% in Group IIIb, respectively (p = 0.033 and p = 0.008, respectively). After adjustments, patient factors for delayed surgery (HR 2.780; 95% CI 1.012-7.640, p = 0.047) were significantly associated with death after hip fracture. CONCLUSIONS: This study demonstrated that delayed surgery was significantly related to 30-day and 1-year mortality. Surgery delay due to drugs' hold and medical comorbidity was related to 30-day mortality after adjustment.

Treatments for acute distal radioulnar joint (DRUJ) instability with distal radius fracture vary from conservative to operative treatment, although it seems to be no consensus regarding which treatment is optimal. This prospective randomized study was designed to compare the clinical outcomes for operative and conservative treatment of acute DRUJ instability with distal radius fracture, according to the presence or absence and type of ulnar styloid process fracture and the degree of its displacement. Between July 2008 and February 2013, we enrolled 157 patients who exhibited an unstable DRUJ during intraoperative manual stress testing (via the ballottement test) after fixation of the distal radius. Patients were classified according to the type of the ulnar styloid process fracture, using preoperative wrist radiography, and each group was divided into subgroups, according to their treatment method. We then compared the clinical outcomes between the conservative and operative treatments, using their range of motion; Disabilities of the Arm, Shoulder, and Hand score; modified Mayo wrist score; and grip strength. At 3 months after surgery, among patients without ulnar styloid process fracture, the flexion-extension range was 79 ± 15° after supination sugar-tong splinting (group A-1), 91 ± 14° after DRUJ transfixation (group A-2), and 89 ± 10° after arthroscopic triangular fibrocartilage complex repair (group A-3); the operative treatments provided greater joint motion ranges than conservative treatment. The groups with ulnar styloid process fractures at the tip (group B) or base (group C) also exhibited better clinical outcomes after the operative treatments, compared with after the conservative treatment. However, at the final follow-up, groups A-1, A-2, and A-3 exhibited similar flexion-extension ranges (122 ± 25°, 119° ± 18°, and 120° ± 16°, respectively) and modified Mayo wrist scores (87 ± 7, 89 ± 8, and 85 ± 9). Thus, the conservative and operative treatments provided similar long-term outcomes, and similar results were observed for patients with ulnar styloid process fracture at the tip or base. The average splint application period for patients who underwent conservative treatment was 6.6 weeks (range, 4-9 weeks). In our practice, conservative treatment (supination sugar-tong splinting) and surgical treatments provided similar long-term outcomes for acute DRUJ instability with distal radius fracture.

Background: Increasing longevity has caused the very old population to become the fastest-growing segment. The number of centenarians (over 100 years old) is increasing rapidly. Fractures in the elderly lead to excessive medical costs and decreased quality of life with socioeconomic burdens. However, little research has thoroughly examined the functional outcomes and mortality of hip fractures in centenarians. Methods: This is a retrospective observational study. Sixty-eight centenarian hip fracture patients were admitted to the 10 institutions from February 2004 to December 2019. Fifty-six patients with 1-year follow-up were finally included. The following data were obtained: sex, age, body mass index, Charlson comorbidity index value on the operation day, Koval's classification for ambulatory ability, type of fracture, the time interval from trauma to surgery, American Society of Anesthesiologists grade, surgery-related complications, and duration of hospital stay. Postoperative Koval's classification (at 1 year after surgery) and information about death were also collected. Multivariate analysis was performed to analyze the risk factors affecting mortality 1 year after surgery. Results: Mortality rates were 26.8% at 6 months and 39.3% at 1 year. The 90-day mortality was 19.6%, and one of them (2.1%) died in the hospital. The 1-year mortality rates for the community ambulatory and non-community ambulatory groups were 29% and 52%, respectively. Only 9 (16.1%) were able to walk outdoors 1 year after surgery. The remaining 47 patients (83.9%) had to stay indoors after surgery. Multivariate analysis demonstrated that the pre-injury ambulatory level (adjusted hazard ratio, 2.884; p = 0.034) was associated with the risk of mortality. Conclusions: We report a 1-year mortality rate of 39.3% in centenarian patients with hip fractures. The risk factor for mortality was the pre-injury ambulatory status. This could be an important consideration in the planning of treatment for centenarian hip fracture patients.

BACKGROUND: The advancement of computer information technology would maximize its potential in operating rooms with touchless input devices. A picture archiving and communication system (PACS) was compared with a touchless input device (LMC-GW), relaying to another person to control a mouse through verbal guidance, and directly controlling a mouse. METHODS: Participants (n = 34; mean age, 29.6 years) were prospectively enrolled and given nine scenarios to compare the three methods. Each scenario consisted of eight tasks, which required 6 essential functions of PACS. Time elapsed and measurement values were recorded for objective evaluation, while subjective evaluation was conducted with a questionnaire. RESULTS: In all 8 tasks, manipulation using the mouse took significantly less time than the other methods (all p < 0.05). Study selection, panning, zooming, scrolling, distance measuring, and leg length measurement took significantly less time when LMC-GW was used compared to relaying to another person (all p < 0.01), whereas there were no significant differences in time required for measuring the angles and windowing. Although the touchless input device provided higher accessibility and lower contamination risk, it was more difficult to handle than the other input methods (all p < 0.01). CONCLUSIONS: The touchless input device provided superior or equal performance to the method of verbal instruction in the environment of operating room. Surgeons agreed that the device would be helpful for manipulating PACS in operating rooms with less contamination risk and disturbance of workflow. The touchless input device can be an alternative option for direct manipulation of a mouse in operation rooms in the future.

ABSTRACT: Factors related to developing postoperative ileus (POI) vary from pharmacologic, inflammatory, hormonal, metabolic, gastrointestinal physiology, neurologic, to psychological factors. Although orthopedic-related incidence of postoperative ileus is about 10%, these studies are limited to spine surgery and pelvic surgery. The purpose of this study was to investigate prevalence of POI and to analyze effect of chewing gum on POI and bowel function in elderly patients after hip fracture surgery.A prospective randomized controlled trial was conducted at the Gyeongsang National University Hospital. Elderly patients with hip fracture who underwent surgery from March 2017 to June 2018 were eligible to participate. Patients were excluded if they had a mastication disability, impaired cognitive function, previous history of gastrointestinal disease, respiratory disease and low oxygen saturation, hip arthroplasty with causes other than hip fractures, acetabular fractures, periprosthetic fractures, or pathological fractures. Patients with consciousness problem by excessive anesthesia were also excluded. Patients were classified into 2 groups by randomization. Group I received sugar-free gum and were encouraged to chew 6âhours following surgery until the first intestinal gas is released. Group II was given the same postoperative procedure and encouraged to consume water after 6 hours.After applying exclusion criteria, 74 patients were finally included. Thirty-one patients were classified to Group I and 43 patients were classified to the Group II. Prevalence of POI in all patients with hip fracture was 63.5% (47/74). Prevalence of POI in Group I was statistically significant lower than that in Group II (Group I: 41%, Group II: 79.1%, Pâ=â.01)The prevalence of POI in elderly patients with hip fracture was 63.5%. Chewing gum had a significant effect on reduction of POI in elderly patients with hip fractures.

OBJECTIVES: This study aimed to analyse the effect of discontinuation of antimicrobial stewardship programme (ASP) activity on the usage pattern of antibiotics. METHODS: An interrupted time-series analysis assessing the trends in antibiotic use was conducted between September 2015 and August 2019 in an 859-bed university-affiliated hospital in Korea, where all ASP activities were discontinued in March 2018. The major activity of the ASP was a restrictive antibiotic programme. RESULTS: The use of restrictive antibiotics increased immediately after the discontinuation of the ASP by 41.06 days of therapy (DOT)/1000 patient-days in the general ward (95% confidence interval (CI) 21.04-61.08) and by 391.04 DOT/1000 patient-days in the intensive care unit (ICU) (95%CI 207.56-574.51). In addition, there were positive changes in the slope for the use of restrictive antibiotics in the general ward (7.06 DOT/1000 patient-days per month, 95%CI 4.63-9.50) and ICU (35.95 DOT/1000 patient-days per month, 95%CI 18.70-53.19). The use of broad-spectrum antibiotics in the general ward significantly decreased (-87.54 DOT/1000 patient-days, 95%CI -149.29 to -25.79). For non-broad-spectrum antibiotics, there were positive changes in the slope in the general ward (16.54 DOT/1000 patient-days per month, 95%CI 12.99-20.09) and ICU (12.85 DOT/1000 patient-days per month, 95%CI 2.32-23.38). CONCLUSIONS: After discontinuation of the ASP, antibiotic usage patterns rapidly returned to the patterns prior to the implementation of the programme.

BACKGROUND: The purpose of this study is to search for reports on the clinical effectiveness of FLS being implemented worldwide through the systematic review, analyze the roles of coordinators in each study, and provide basic data for the development of future coordinator education programs. METHODS: A systematic search of the literature using the Medline, PubMed, and EMBASE databases and the Cochrane Library was conducted for using the following keywords: 'osteoporosis' AND 'fractures' AND 'secondary prevention'. Finally, 65 studies are included in this study. RESULTS: At the coordinator-based fracture liaison service (FLS) center, the coordinator (often a nurse) acts as a central player in the establishing of patient connections, orthopedic surgeons, radiologists, and attending physicians. Coordinators help bridge the nursing gap by supporting identification, investigation, initiation of treatment, and patient follow-up. Medics has opened the way to effectively manage patients at high risk of developing another fracture. In addition, nurses are in a unique and important role as nurses responsible for enhancing their daily lives by building relationships with patients and families. CONCLUSIONS: The coordinator in the FLS program plays an important role in the multidisciplinary management of vulnerable fractures, as well as in the diagnosis and treatment of osteoporosis and in maintaining continuity of treatment. In the future, the broader role of coordinators should be systematically organized and developed into accredited educational programs.
RESUMEN
Osteoporosis and osteoporosis related fractures contribute a large part of the medical cost in developed countries. Considering the preventive effect of osteoporotic medications, high rate of mortality and complications, poor quality of life after osteoporosis related fractures, the growing trend of older populations in the future, osteoporosis and osteoporosis related fractures are important targets of preventive treatment and also targets of socioeconomic cost reduction. Treating osteoporosis and preventing osteoporosis related fractures have become an essential element in Korean medical system. Despite the various differences in the health care system, hospitals in many other countries are operating fracture liaison service and they have confirmed its cost-effectiveness. In Korea's health care system, further research on cost-effectiveness as well as its clinical effects is needed.
RESUMEN
BACKGROUND/OBJECTIVE: The purpose of this study is to analyze the effect of surgical methods on mortality and the relative risk of patients who underwent internal fixation (IF) or hemiarthroplasty (HA) after being diagnosed as a pertrochanteric fracture over 65 years old in a Korean nationwide cohort with a single insurance medical system. METHODS: The Korean National Health Insurance Service-Senior cohort (NHIS-Senior, NHIS-2018-2-111) was used in this study. The eligibility criteria for incident hip fracture patients were the following: (1) first-time admission to acute care hospitals (index admission) with pertrochanteric fracture (ICD-10 S721), (2) three years of hip fracture-free period, (3) recipients of typical surgeries including IF, HA, (4) age between 65 and 99. RESULTS: a total of 7223 patients were enrolled in the cohort. There were 1662 patients (23%) in the HA group and 5561 patients (77%) in the IF group. Mortality rates of the IF group and HA group were 13.46 and 17.94 cases per 100 person-years, respectively. In the multivariable-adjusted Cox proportional hazard model, the HA group had 1.22 times more hazard of all-cause mortality than IF group (aHR 1.22, 95% CI 1.13-1.32). In subgroup analysis, aged 65-79 and female patients showed a prominent association between surgery type and mortality (aHR 1.52, 95% CI 1.29-1.79). CONCLUSIONS: In patients with pertrochanter fracture over 65 years, 1.22-fold mortality rate was observed when HA was performed compared to that of IF, and the difference in mortality was particularly prominent within 1-year after surgery.

INTRODUCTION: We designed a comparative study using elderly hip fracture patients with and without heart failure (HF). The purpose of this study was to assess 1) prevalence of HF, compare 2) early and late mortality after elderly hip fracture between HF and non-HF patients and to assess 3) risk factors of mortality after hip fractures in elderly patients with HF. In addition, we also investigated 4) whether there is a difference in mortality according to the severity of left ventricular (LV) systolic dysfunction classified by LV ejection fraction (EF) in HF patients through subgroup analysis. METHODS: This study included 1992 patients (1992 hips) who were diagnosed as having unilateral femoral neck or intertrochanteric fractures and who underwent surgery at two hospitals between January 2004 and June 2018. The patients were categorized into a non-HF group (1782 patients) and a HF group (210 patients; mild [119 patients] and moderate-to- severe HF subgroups [91 patients]). The cumulative crude mortality rate was calculated, and 30-day, 60-day, 3-month, 6-month, and 1-year mortality rates were compared between the non-HF and HF. Logistic regression analysis was conducted to identify independent factors associated with mortality. RESULTS: Of 1992 patients, 210 (10.5%) patients were diagnosed with HF. The 30-day, 60-day, 3-month, 6-month, and 1-year postoperative cumulative mortality rates were respectively 1.6%, 3.6%, 5.1%, 8.4%, and 12.9% in the non-HF group, and 5.7%, 9.5%, 12.4%, 17.1%, and 25.2% in the HF group (p ≤ 0.001). The factors that affected 1-year mortality were sex (OR, 2.10; 95% CI, 1.62-2.72; p < 0.001) and age (OR, 1.04; 95% CI, 1.02-1.06; p < 0.001) and presence of HF (OR, 1.62; 95% CI, 1.45-1.86; p = 0.005). In subgroup analysis, the factors that affected 30-day mortality were only moderate-to-severe HF (OR, 4.01; 95% CI, 1.10-8.78; p = 0.009). CONCLUSIONS: In elderly patients with hip fracture, the comparison between the HF and non-HF patients revealed that HF was an independent factor of mortality at a minimum of 1-year follow-up, and severity of LV systolic dysfunction classified by LVEF in patients with hip fracture was also a risk factor of 30-day mortality.

BACKGROUND: The purposes of this study were to develop a machine learning-based implant recognition program and to verify its accuracy. METHODS: Postoperative anteroposterior (AP) X-rays (≥300 dpi) were collected of patients who underwent total hip arthroplasty. X-rays with a wire or plate added and those without a true anteroposterior view were excluded. A total of 170 X-ray images of hip implants from 29 brands were collected from five hospitals and a Google image search. These collected images were manually reorganised to ensure appropriate labelling. Collected images were preprocessed to have grey-scaled pixels with histogram equalisation for efficient training. Images varied by +10/-10°, and 3606 unique images derived from the original 170 images were created for training. Discussion of the validation set being derived 25% of training set. The recognition model structure consisted of two steps: object detection and clustering. Model training was performed with Keras deep learning platform. RESULTS: The 170 X-ray images of hip implants were used to build a stem detection model using YOLOv3. Manually labelled images were successfully trained into the stem detection model. Evaluation of 58 newly labelled X-ray images showed highly accurate stem detection (mean average precision > 0.99). Fully connected layers generated 29 class outputs. After training, a receiver operating characteristic curve was generated with a test set containing 25% of all stem-cropped images, yielding an area under the curve of 0.99. CONCLUSION: Femoral stem identification in patients with total hip arthroplasty was very accurate. This technology could be used to collect large-scale implant information. THE TRANSLATIONAL POTENTIAL OF THIS ARTICLE: This program has the following clinical relevance. First, we can prepare the implants needed for revision surgery by identifying the old types of implants. Second, it can be used to diagnose peripheral osteolysis or periprosthetic fracture by further developing the ability to sensitise implant detection. Third, an automated implant detection system will help organise imaging data systematically and easily for arthroplasty registry construction.
