Aims. Performance indicators are increasingly used to evaluate the quality of healthcare provided to patients with a hip fracture. The aim of this review was to map the variety of performance indicators used around the world and how they are defined. Methods. We present a mixed methods systematic review of literature on the use of performance indicators in hip fracture care. Evidence was searched through 12 electronic databases and other sources. A Mixed Methods Appraisal Tool was used to assess methodological quality of studies meeting the inclusion criteria. A protocol for a suite of related systematic reviews was registered at PROSPERO (CRD42023417515). Results. A total 24,634 articles were reviewed, of which 171 met the criteria of the review. Included studies were heterogenous in design and came from varied healthcare systems in 34 different countries. Most studies were conducted in high-income countries in Europe (n = 118), followed by North America (n = 33), Asia (n = 21), Australia (n = 10), and South America (n = 2). The highest number of studies in one country came from the UK (n = 45). Only seven of the 171 studies (< 2,000 participants) were conducted across ten low- and middle-income countries (LMICs). There was variation in the performance indicators reported from different healthcare systems, and indicators were often undefined or ambiguously defined. For example, there were multiple definitions of 'early' in terms of surgery, different or missing definitions of ‘mobilization’, and variety in what was included in an ‘orthogeriatric assessment’ in hip fracture care. However, several performance indicators appeared commonly, including time to surgery (n = 142/171; 83%), orthogeriatric review (n = 30; 17%), early mobilization after surgery (n = 58; 34%), and bone health assessment (n = 41; 24%). Qualitative studies (n = 18), mainly from high-income countries and India, provided evidence on the experiences of 192 patients and 138 healthcare professionals with regard to the use of performance indicators in clinical care and rehabilitation pathways. Themes included the importance of education and training in parallel with the introduction of performance indicators, clarity of roles with the clinical team, and the need for restructuring or integration of care pathways. Conclusion. This review identified a large number of performance indicators related to the delivery of healthcare for patients with a hip fracture. However, their definitions and thresholds varied across studies and countries. Evidence from LMICs is sparse. Both qualitative and quantitative evidence indicates that there remains a pressing need for further research into the use and standardization of performance indicators in hip fracture care and their influence on patient outcomes and economic costs.

Introduction. Wound surveillance has been reported to result in a significant fall in the incidence of wound sepsis in total knee arthroplasty (TKA). However, there is currently little guidance on the definition of surgical wound infection that is best to be used for surveillance. The purpose of this study was to assess the agreement between three common definitions of surgical wound infection as a performance indicator in TKA; (a) the CDC 1992 definition, (b) the NINSS modification of the CDC definition and (c) the ASEPSIS scoring method applied to the same series of surgical wounds. Methods. A prospective study of 500 surgical wounds in patients who underwent knee arthroplasties between May 2002 and December 2004 from a single tertiary centre were assessed according to the different definitions of surgical wound infection. Results. A total of 500 wounds were assessed in 482 patients. Mean age of patients was 70+/−11 years, 61.6% were females, duration of surgery was 101+/−49 minutes and mean follow-up was 35.2+/−25.7 months. The most commonly isolated species were Coagulase negative staphylococci (33.3%), Staphylococcus aureus (25%) and Pseudomonas aeruginosa (16.6%). The mean percentage of wounds classified as infected differed substantially with different definitions: 5.8% with the CDC definition, 3.6% with the NINSS version and 2.2% with an ASEPSIS score > 20. When superficial infections (according to CDC category) were included, 5.2% (26) of all observed wounds received conflicting diagnoses, and 1.4% (7) were classified as infected by both ASEPSIS and CDC definitions. When superficial infections were excluded, the two definitions estimated about the same overall percentage infection (2.2% and 2.6% respectively), but there were almost three times as many conflicting infection diagnoses (n=14) as concordant ones (n=5). Conclusion. Distinctions in surgical wound infection definitions contribute to notable differences in how infections are classified after TKA. Even small changes made to the CDC definition, as with the NINSS version, caused major variation in estimated percentage of wound infection. A single definition used consistently can show changes in wound infection rates over time at a single centre. However, differences in interpretation prevent comparison between different centres

There has been extensive research into neck of femur fractures in the elderly. Fragility non-hip femoral fractures share many of the same challenges [1]. Surgical management is complex, patients are frail and mortality rates have been reported as high as 38% [2]. Despite this, relatively little data is available evaluating the level of MDT care provided to non-hip femoral fractures. This audit aimed to evaluate the standard of MDT care provided for patients with non-hip femoral fractures according to the NHFD key performance indicators. The following fractures were included in the dataset: distal femoral, femoral shaft and peri-prosthetic femoral. Patients under 65 were excluded. Data was retrospectively collected using post-operative and medical documentation. Performance was assessed according to five key performance indicators:. Did orthogeriatrics review the patient within 72-hours?. Was surgery performed within 36-hours?. Was the patient weight bearing post-operatively?. Was a confusion assessment completed?. Was the patient discharged home?. 38 patients met the inclusion criteria. 84% of patients were seen by orthogeriatrics within 72 hours of admission. 32% of patients were operated on within 36-hours of admission, with time to theatre exceeding 36-hours in 92% of peri-prosthetic fractures. 37% of patients were not advised to full weight bear post operatively. 84% of patients received a confusion assessment whilst 61% of patients were discharged to their prior place of living. Our results suggest that non-hip femoral fractures do not receive the same standard of MDT care as neck of femur fractures. Greater prioritisation of resources should be given to this patient subset so that care is equivalent to hip-fracture patients. Time to surgery is a particular area for improvement, particularly in peri-prosthetic fractures, a trend that is mirrored nationally. Greater emphasis should be placed on encouraging full-weight bearing post-operatively to prevent post-surgical complications

One of the most important sequelae to ageing is osteoporosis and subsequently hip fractures. Hip fractures are associated with major morbidity, mortality and costs. Most patients require surgery to restore mobility. Provision of surgery and its complications is poorly understood in South Africa. Our aim was to collect and report current hip fracture care at four centres in South Africa, as well as reporting surgical and general patient outcomes. A three year retrospective cohort at four centres will be described, focussing on provision of surgical care, mortality, types of surgery and complications. We identified 562 patients who had surgical intervention for fragility fractures, 66% were females. Forty nine percent had open reduction and internal fixation, 28% had hemi-arthroplasty replacement whilst 23% had total hip replacements. Twenty percent of patients had operative intervention within 36 hours of presentation to the emergency department. Mortality was 9% at 30 days. The most common complications were lower respiratory infections (29%), urinary tract infections (21%) and surgical site infections (9%). This is the largest cohort of surgically treated hip fracture from South Africa. Proportions of patients receiving different surgical interventions such as THR are comparable to the broader literature. However a number of key performance indicators such as surgery within 36 hours are challenging to meet. Given the changing demographics of South Africa, this study provides an early insight to contemporary care and may help provide direction for broader national strategies for reporting and improving hip fracture care

Aims. Postoperative delirium (POD) and postoperative cognitive decline (POCD) are common surgical complications. In the UK, the Best Practice Tariff incentivizes the screening of delirium in patients with hip fracture. Further, a National Hip Fracture Database (NHFD) performance indicator is the reduction in the incidence of POD. To aid in its recognition, we sought to determine factors associated with POD and POCD in patients with hip fractures. Methods. We interrogated the NHFD data on patients presenting with hip fractures to our institution from 2016 to 2018. POD was determined using the 4AT score, as recommended by the NHFD and UK Department of Health. POCD was defined as a decline in Abbreviated Mental Test Score (AMTS) of two or greater. Using logistic regression, we adjusted for covariates to identify factors associated with POD and POCD. Results. Of the 1,224 patients presenting in the study period, 1,023 had complete datasets for final analysis. POD was observed in 242 patients (25%). On multivariate analysis only preoperative AMTS and American Society of Anesthesiologists grade (ASA) were independent predictors of POD. Every point increase in AMTS was associated with a fall in the odds of POD by a factor of 0.60 (95% confidence interval (CI) 0.56 to 0.63, p < 0.001). Every grade increase in ASA led to a 1.7-fold increase in the odds of POD (95% CI 1.13 to 2.50, p = 0.009). A preoperative AMTS of less than 8 was strongly predictive of POD with area under the receiver operating characteristic of 0.86 (95% CI 0.84 to 0.89). Only ASA was predictive of POCD—every grade increase in ASA led to a 2.6-fold increase in the odds of POCD (95% CI 1.7 to 4.0, p < 0.001). Conclusion. POD and POCD are common in the hip fracture patients. Preoperative AMTS and ASA are strong predictors of POD, and ASA predictive of POCD. This may aid in the earlier identification of those most at risk and suited for the patient consent and decision-making process. Cite this article: Bone Joint J 2020;102-B(12):1675–1681

Aim and objectives of the study: To assess the true incidence and reasons for readmission after fracture neck of femur treatment and its effect on Trust star rating. Introduction: Star ratings (zero to three) show how well a Trust is performing and is awarded against a set of performance indicators (Patient Focus, Capacity and Capability Focus and Clinical Focus) as laid by CHAI. These indicators cover the standards and outcomes of treatment given. CHAI reports 9% readmission as an emergency within 28 days, and assumes that a proportion of the observed readmissions are potentially avoidable. Materials and Methods: An audit done by the managers found 15 (19%) cases of readmission of fracture neck of femur during April to October 2004. We did Re audit by reviewing the exact cause for readmissions in all the cases. Results: Out of 15 cases identified by the managers only 4 (5.19%) were true readmission, which is below the national average.8 readmissions were for medical reasons, 3 for social reasons and rest 4 were related to fracture complications like infection. Conclusion: Star ratings (zero to three) reflect Trust performance and are awarded against a set of performance indicators, which cover the standards, and outcomes of treatment given (Patient Focus, Capacity and Capability Focus and Clinical Focus) as laid by CHAI. We conclude that audit should be done as a team-work involving all responsible health care professionals and proper uniform coding system needs to be followed to obtain correct results

Total knee arthroplasty (TKA) is considered as one of the most successful and cost-effective medical interventions yet it is consistently reported that up to 20% of patients are dissatisfied with their outcomes. Patient satisfaction is correlated with the fulfillment of expectations and an important aspect of this involves good surgeon-patient communication, which itself is a contributor to TKA satisfaction. The purpose of this study was to develop and test a checklist intended to enhance the quality of surgeon-patient communication by optimizing the surgeon's role in helping patients set (or reset) and manage post-TKA expectations that are realistic, achievable, and most importantly, patient-specific. In this prospective mixed methods study, a communication checklist was developed from the analysis of interviews with patients who were between six weeks and six months post-TKA. Four orthopaedic surgeons then used the checklist to guide discussions with patients about post-operative expectations and outcomes during follow-up visits between six weeks and six months. A visual analogue scale was used to survey two groups of patients on five measures of satisfaction: the standard of care communication group and the intervention group who had received the checklist. The mean scores of the two groups were compared using independent t-tests. The duration of follow-up visits was also tracked to determine if the checklist took significantly more time in practice. Themes from the qualitative analysis of eight patient interviews incorporated into the checklist included pain management, medication, physiotherapy, and general concerns and questions. The quantitative study comprised 127 participants, 67 in the standard of care communication group and 60 in the checklist group. There were no significant group differences in gender, BMI, comorbidities, post-operative complications, marital or occupational status, however the standard of care group was older by six years (p < .001). The checklist group reported significantly greater satisfaction on four of the five measures of satisfaction: TKA satisfaction and expectations met (p = .017), care and concern shown by the surgeons (p = .011), surgeons' communication ability (p = .008), and satisfaction with time surgeons spent with patients during follow-up visits (p < .001). Satisfaction with the TKA for relieving pain and restoring function was not significant (p = .064). Although the checklist increased the average clinic visit time by only 1 minute, 51 seconds, it was significantly greater (p = .001). The impact of age and gender on satisfaction was explored using a two-way analysis of variance. No significant effects or interactions were observed. Checklists have been shown to decrease medical errors and improve overall standards of patient care but no published research to date has used a communication checklist to enhance orthopaedic surgeon-patient communication. The present findings indicate that this simple tool can significantly increase patient satisfaction. This has practical significance because patient satisfaction is a metric that is increasingly used as a key performance indicator for surgeons and health care institutions alike. Increased TKA satisfaction will benefit patients, surgeons, and the health care system overall

In computer assisted orthopaedic surgery, intraoperative registration is commonly performed by fitting features acquired from the exposed bone surface to a preoperative virtual model of the bone geometry. In cases where the acquired spatial measurements are unreliable or have been inappropriately chosen, the registration result can degenerate. Current performance indicators, such as the root mean squared (RMS) error and the spatial distribution of the registered feature errors may not be sufficient to warn the surgeon of such a case. In this study, statistical analysis is applied to the registration outcomes of perturbed variants of a collected point set. In this way, it is possible to assess the ability of the original set to represent the underlying surface, taking into account the distribution of the points as well as errors introduced during the acquisition process. Confidence measures are calculated to predict the reliability of the original registration result and therefore the robustness of the point set itself. For proof of concept, this method has been tested in simulation with a CT-generated tibia model. The algorithm was used to identify the 10 best performing of a population of 1000 randomly generated point sets. All registration outcomes produced by these point sets were found to be superior to those resulting from sets of the same size produced manually using an optimised point-acquisition protocol. Preliminary results suggest that this method, alongside the standard RMS and residual point error distribution, may be used to provide the surgeon with a reliable indication of registration outcome in the operating room

Introduction. Stress shielding is one of the major concerns of load bearing implants (e.g. hip prostheses). Stiff implants cause stress shielding, which is thought to contribute to bone resorption1. On the contrary, low-stiffness implants generate high interfacial stresses that have been related to pain and interfacial micro-movements². Different attempts have been made to reduce these problems by optimizing either the stem design3 or using functionally graded implants (FGI) where the stem's mechanical properties are optimized4. In this way, new additive manufacturing technologies allow fabricating porous materials with well-controlled mesostructure, which allows tailoring their mechanical properties. In this work, Finite Element (FE) simulations are used to develop an optimization methodology for the shape and material properties of a FGI hip stem. The resorbed bone mass fraction and the stem head displacement are used as objective functions. Methodology. The 2D-geometry of a femur model (Sawbones®) with an implanted Profemur-TL stem (Wright Medical Technology Inc.) was used for FE simulations. The stem geometry was parameterized using a set of 8 variables (Figure 1-a). To optimize the stem's material properties, a grid was generated with equally spaced points for a total of 96 points (Figure 1-b). Purely elastic materials were used for the stem and the bone. Two bone qualities were considered: good (Ecortical=20 GPa, Etrabecular=1.5 GPa) and medium (Ecortical=15 GPa, Etrabecular=1 GPa). Poisson ratio was fixed to v=0.3. Loading corresponded to stair climbing. Hip contact force along with abductors, vastus lateralis and vastus medialis muscles were considered5 for a bodyweight of 847 N. The resorbed bone mass fraction was evaluated from the differences in strain energy densities between the intact bone and the implanted bone2. The displacement of the load point on the femoral head was computed. The optimization problem was formulated as the minimization of the resorbed bone mass fraction and the head displacement. It was solved using a genetic algorithm. Results. For the Profemur-TL design, bone resorption was around 36% and 56% for good and medium bone qualities, respectively (Fig. 2). The corresponding head displacements were 11.75 mm and 21.19 mm. Optimized solutions showed bone resorption from 15% to 26% and from 44% to 65% for good and medium bone qualities, respectively. Corresponding head displacements ranged from 11.85 mm to 12.25 mm and from 16.9 mm to 22.6 mm. Conclusion. The obtained set of solutions constitutes an improvement of the implant performance for this functionally graded implant (FGI) compared to the original implant for both bone qualities. From these simulations, the final solution for the FGI could be chosen based on manufacturing restrictions or another performance indicator

Aims

This study aimed to determine the expression and clinical significance of a cartilage protein, cartilage oligomeric matrix protein (COMP), in knee osteoarthritis (OA) patients.

Aims

The aim of this study was to describe the current pathways of care for patients with a fracture of the hip in five low- and middle-income countries (LMIC) in South Asia (Nepal and Sri Lanka) and Southeast Asia (Malaysia, Thailand, and the Philippines).

Aims

National hip fracture registries audit similar aspects of care but there is variation in the actual data collected; these differences restrict international comparison, benchmarking, and research. The Fragility Fracture Network (FFN) published a revised minimum common dataset (MCD) in 2022 to improve consistency and interoperability. Our aim was to assess compatibility of existing registries with the MCD.

Aims

A substantial fraction of patients undergoing knee arthroplasty (KA) or hip arthroplasty (HA) do not achieve an improvement as high as the minimal clinically important difference (MCID), i.e. do not achieve a meaningful improvement. Using three patient-reported outcome measures (PROMs), our aim was: 1) to assess machine learning (ML), the simple pre-surgery PROM score, and logistic-regression (LR)-derived performance in their prediction of whether patients undergoing HA or KA achieve an improvement as high or higher than a calculated MCID; and 2) to test whether ML is able to outperform LR or pre-surgery PROM scores in predictive performance.

Aims

The aim of this study was to evaluate the suitability, against an accepted international standard, of a linked hip fracture registry and routinely collected administrative dataset in England to embed and deliver randomized controlled trials (RCTs).

Aims

The aim of this study was to describe services available to patients with periprosthetic femoral fracture (PPFF) in England and Wales, with focus on variation between centres and areas for care improvement.

Aims

This study aims to determine difference in annual rate of early-onset (≤ 90 days) deep surgical site infection (SSI) following primary total knee arthroplasty (TKA) for osteoarthritis, and to identify risk factors that may be associated with infection.

Aims

This is a multicentre, prospective assessment of a proportion of the overall orthopaedic trauma caseload of the UK. It investigates theatre capacity, cancellations, and time to surgery in a group of hospitals that is representative of the wider population. It identifies barriers to effective practice and will inform system improvements.

Aims

Understanding of open fracture management is skewed due to reliance on small-number lower limb, specialist unit reports and large, unfocused registry data collections. To address this, we carried out the Open Fracture Patient Evaluation Nationwide (OPEN) study, and report the demographic details and the initial steps of care for patients admitted with open fractures in the UK.

Aims

The purpose of this study was to determine the weightbearing practice of operatively managed fragility fractures in the setting of publically funded health services in the UK and Ireland.
