With an ageing population and an increasing number of primary arthroplasties performed, the revision burden is predicted to increase. The aims of this study were to 1. Determine the revision burden in an academic hospital over a 11-year period; 2. identify the direct hospital cost associated with the delivery of revision service and 3. ascertain factors associated with increased cost. This is an IRB-approved, retrospective, single tertiary referral center, consecutive case series. Using the hospital data warehouse, all patients that underwent revision hip or knee arthroplasty surgery between 2008-2018 were identified. 1632 revisions were identified (1304 patients), consisting of 1061 hip and 571 knee revisions. The majority of revisions were performed for mechanical-related problems and aseptic loosening (n=903; 55.3%); followed by periprosthetic joint infection (n=553; 33.9%) and periprosthetic fractures (176; 10.8%). Cost and length of stay was determined for all patient. The direct in-hospital costs were converted to 2020 inflation-adjusted Canadian dollars. Several patients- (age; gender; HOMR- and ASA-scores; Hemoglobin level) and surgical- (indication for surgery; surgical site) factors were tested for possible associations. The number of revisions increased by 210% in the study period (2008 vs. 2018: 83 vs. 174). Revision indications changed over study period; with prevalence of fracture increasing by 460% (5 in 2008 vs. 23 in 2018) with an accompanying reduction in mechanical-related reasons, whilst revisions for infection remained constant. The mean annual cost over the entire study period was 3.9 MMCAD (range:2.4–5.1 MMCAD). The cost raised 150% over the study period from 2.4 MMCAD in 2008 to 3.6 MMCAD. Revisions for fractured had the greatest length of stay, the highest mean age, HOMR-score, ASA and cost associated with treatment compared to other revision indications (p < 0 .001). Patient factors associated with cost and length of stay included ASA- and HOMR-scores, Charlson-Comorbidity score and age. The revision burden increased 1.5-fold over the years and so has the direct cost of care delivery. The increased cost is primarily related to the prolonged hospital stay and increased surgical cost. For tertiary care units, these findings indicate a need to identify strategies on improving efficiencies whilst improving the quality of patient care (e.g. efficient ways of reducing acute hospital stay) and reducing the raise of the economic burden on a publicly funded health system

Background. Total hip arthroplasty (THA) has become one of the most commonly performed elective procedures. Today, there are nearly 50 000 annual hospitalizations for hip replacement surgery in Canada. This number is projected to increase significantly with the aging population. Periprosthetic joint infection (PJI) is the 3rd leading cause of failure following THA and is reported to occur at an incidence of 1–3%. A two-stage revision THA is the current gold standard treatment and this has a tremendous economic impact on the healthcare system. The purpose of this study is to create an accurate cost estimate of two-stage revision THA and, in turn, evaluate the economic burden of PJI as it compares to primary THA in a Canadian healthcare context. Methods. We conducted a retrospective review of primary THA cases and two-stage revision THA for PJI at our institution. Patients were matched for age and BMI. We recorded all costs associated with each procedure, including: OR time, equipment, length of hospital stay, readmission rates, and any other inpatient resource use. Unit costs were obtained using administrative data from the case costing department at London Health Sciences Centre. Billing fees associated with the procedure were obtained from the Ontario Schedule of Benefits. Descriptive statistics were used to summarize the demographic characteristics of patients, hospital costs and resource use data. Patients with PJI were compared to the matched cohort of primary THA using the t-test (for continuous variables), and the chi-square test (for categorical variables). Results. Fifty consecutive cases of revision THA were matched to 50 patients who underwent uncomplicated primary THA between 2006 and 2014. Periprosthetic infection was associated with a significant increase in hospital stay (26.5 vs. 2.0; t=4.95, p<0.001), clinic visits (9.5 vs. 3.8; T= 6.49, p<0.001), readmission rates (12 vs. 1; X. 2. 11.1, p<0.001) and overall cost ($39 953 vs. $7 460; T=73, p<0.001) in comparison to the primary arthroplasty cohort. Conclusion. Two-stage revision for infected THA is a significant economic burden to the healthcare system. Our data suggests a 5-fold increase in healthcare cost when compared to primary THA. This may be an important consideration when distributing resources among Canadian tertiary care centres

Introduction. Total knee and hip arthroplasty were the main arthroplasty surgery performed in Brazil. In Brazil, around 50% of arthroplasty surgeries are performed by the public health system, knowing as SUS . 1. SUS is the biggest public and universal health system in the world, attending 100% of the Brazilian population (220 million), with 2020's expected budget of US$ 31 billion . 2,3. . The National Institute of Clinical Excellence utilizes the QALY system (Quality adjustment year life)to calculate the best cost-benefit between medical interventions . 4. In compliance with the study, an operated person has a QALY index of £5000 while a non-operated person has an index of £7182. In March 2020, due to the COVID-19 pandemics, the Brazilian Health Ministry oriented for the postponing of elective surgery, to prioritize combating the virus . 5. This postponing, it was important but will cause an impact in the economy at the public health system from Brazil this year and in the next years. Therefore, this study aims to present the economic impact caused by COVID-19 pandemics in the public heal system, SUS, of Brazil. Methods. Data about total hip arthroplasty (THA) and total knee arthroplasty (TKA) in Brazil were collected from the TABNET portal of the Brazilian Health Ministry/Datasus . 6. It was collected information per month about hospitalization authorization (AIH), and total cost per AIH. The information regards the period of January to June from years 2015 to 2020. Results and Discussion. After the orientation in march 2020 to postpone elective surgery, there was a reduction of up to 91% in total knee arthroplasty (TKA) and 76% in total hip arthroplasty (THA), compared to the same period in the previous years (see Figure 1). This represents a reduction of more than 5000 surgeries in the first semester. According to Brazilian doctors, the retention of surgeries will result in excessive demand for the sector in the upcoming months . 7. . Due to the reduction of the AIH, which occurs a reduction US$3,881,494 of the budget destined for arthroplasty surgeries in the first semester of 2020 (see Figure 2), being used to the combat of COVID-19. Consequently, the purchase of new hip and knee prostheses decreases, harming the implant sales sector in Brazil. Furthermore, by the QALY system, the cost of a non-operated patient is up to 43% bigger than that of an operated patient. Thus, this will generate an increase in the expenses of the SUS in the upcoming months or years. Conclusion. The COVID-19 pandemics generate the need of postponing elective surgery of the SUS, such as total hip and knee arthroplasty. Because of this, there was a reduction of 67% of the number and expense of knee and hip arthroplasties in the first semester of 2020. This generates an economic loss for the implants companies and it will increase overly the demand for new surgeries in the upcoming months or years.

Total hip arthroplasty (THA) has become one of the most commonly performed elective procedures. Today, there are nearly 50 000 annual hospitalisations for hip replacement surgery in Canada. This number is projected to increase significantly with the aging population. Periprosthetic joint infection (PJI) is the 3rd leading cause of failure following THA and is reported to occur at an incidence of 1–3%. A two-stage re-vision THA is the current gold standard treatment and this has a tremendous economic impact on the healthcare system. The purpose of this study is to create an accurate cost estimate of two-stage revision THA and, in turn, evaluate the economic burden of PJI as it compares to primary THA in a Canadian healthcare context. We conducted a retrospective review of primary THA cases and two-stage revision THA for PJI at our institution. Patients were matched for age and BMI. We recorded all costs associated with each procedure, including: OR time, equipment, length of hospital stay, readmission rates, and any other inpatient resource use. Unit costs were obtained using administrative data from the case costing department at London Health Sciences Centre. Billing fees associated with the procedure were obtained from the Ontario Schedule of Benefits. Descriptive statistics were used to summarise the demographic characteristics of patients, hospital costs and resource use data. Patients with PJI were compared to the matched cohort of primary THA using the t-test (for continuous variables), and the chi-square test (for categorical variables). Twenty consecutive cases of revision THA were matched to 20 patients who underwent uncomplicated primary THA between 2006 and 2014. Periprosthetic infection was associated with a significant increase in hospital stay (26.5 vs. 2.0; p<0.001), clinic visits (9.5 vs. 3.8; p<0.001), readmission rates (12 vs. 1; p<0.001) and overall cost ($39 953 vs. $7 460; p<0.001) in comparison to the primary arthroplasty cohort. Two-stage revision for infected THA is a significant economic burden to the healthcare system. Our data suggests a 5-fold increase in healthcare cost when compared to primary THA. This may be an important consideration when distributing resources among Canadian tertiary care centres

Introduction. Management of complex fractures poses a significant challenge. Evolving research and changes to national guidelines suggest better outcomes are achieved by transfer to specialist centres. The development of Major Trauma Networks was accompanied by relevant financial arrangements. These do not apply to patients with closed fractures referred for specialist treatment by similar pathways. Despite a surge in cases transferred for care, there is little information available regarding the financial impact on receiving institutions. Materials & Methods. This retrospective study examines data from a Level 1 trauma centre. Patients were identified from our electronic referral system, used for all referrals. Transferred adult patients, undergoing definitive treatment of acute isolated closed tibial fractures, were included for a 2-year period. Data was collected using our clinical and Patient Level Information and Costing (PLICS) systems including coding, demographics, treatment, length of stay (LOS), total operative time, number of operations, direct healthcare costs, and NHS reimbursements. Results. 104 patients were identified, 23 patients were treated by internal fixation and 81 with circular frames. Patients required a median of 190 minutes of total operative time and 6 days of hospital stay at a median cost of £16,233 each, median reimbursement was £10,625. The total cost of treatment for all 104 patients was £2,205,611 and total reimbursement was £1,391463, the median deficit per patient being £5825. The overall deficit over the 2 years was £814,148. Conclusions. This study reveals a considerable economic burden associated with treating complex tibial fractures. It should be emphasised that these do not include patients referred for fracture-related infection or non-union, who may also incur similar deficits in recovered costs. These findings emphasise the importance of understanding and addressing the financial implications of managing tertiary referral orthopaedic trauma patients to ensure efficient and sustainable resource allocation

Introduction. The rate of technological innovation in procedural total knee arthroplasty has left little time for critical evaluation of a new technology before the adoption of even newer modalities. With more drastic financial restrictions being placed on operating room spending, orthopaedic surgeons are now required to provide excellent results on a budget. It is integral that both clinical efficacy and cost-effectiveness of these intraoperative technologies be fully understood in order to provide patients with effectual, economically conscious care. The purpose of this qualitative analysis of literature was to evaluate clinical and economic efficacy of the three most prominent technologies currently used in TKA: computer navigation, patient-specific instrumentation, and kinetic sensors. Methods. Three hundred and ninety one publications were collected; 100 were included in final qualitative analysis. Criteria for inclusion in the analysis was defined only insofar as that each piece assessed one of the above listed aspects of the three technologies Literature included in the final evaluation contained background information on each respective technology, clinical outcomes, revision rates, and/or cost analyses. All comparisons were conducted in a strictly qualitative manner, and no attempts were made to conduct interstudy statistical analyses due to the high level of variability in methodology and data collected. Results. Navigation. Navigation was designed to reduce alignment and component positioning outliers. Many surgeons have argued that its results are no better than that achieved by manual techniques. Some studies have shown that clinical outcomes have improved in navigated TKA patients, but an abundance of research suggests that this is not the case. In consideration of the expense of this technology, coupled with inconclusive results, navigation does not, at this time, seem to fit the schema for significantly reducing the rate of revision and operative cost. PSI. Patient-specific instrumentation was designed to reduce the expense of navigation systems, simplify computer-assisted methods, and improve functional outcomes. However, a majority of research has suggested that PSI is either no better, or even worse, at alignment accuracy than manual techniques. Very few publications have been able to attest to any significant increase in functional outcomes scores of PSI patients, over the scores of navigation or manual TKA. Kinetic Sensors. Kinetic sensor technology has been engineered to quantify soft-tissue balance, improve rotational alignment, and decrease the risk of post-operative complications. Albeit a young device, the sparse literature that exists shows promising results. The margin of error for detecting loads has been shown to be low, the sensors have successfully measured subtle imbalance that leads to altered gait kinematics, and has shown significant improvement in several patient-reported outcomes measures in balanced patients. Discussion. This review shows that not all modalities are created equal, and demonstrates that the cost of some technologies may not yield a clinical or time-saving payoff for the patient and hospital. While kinetic sensor devices seem to be the most promising modality, more research will be necessary to confirm its advantages over time. But, great care must be taken when adopting any novel technology; “new” does not always mean “improved”

Introduction

Individuals with significant hip and knee trauma receive total knee (TKA) and total hip arthroplasty (THA) as definitive end-stage procedures. In Aotearoa, injury-related costs, including workers compensation, may be funded by ACC. With a steady increase of arthroplasty procedures in Aotearoa, we aim to understand the magnitude and characteristics of such procedures to inform future healthcare strategies.

Guidelines on the care of the seriously injured have led to widespread changes in clinical practice. The ‘hub and spoke’ model of trauma care means increasing numbers of patients with complex problems are concentrated into regional centres. Though providing the highest standards of treatment, this has cost implications for the receiving unit, particularly given the Department of Health's move towards a ‘Payment by Results’ model of health provision. We undertook an economic evaluation of complex limb reconstruction within our tertiary referral unit. Patients referred to the complex trauma service were identified. Patients were assigned to either a ‘complicated’ or ‘straightforward’ group by two consultant surgeons, based on the nature of their treatment. 5 cases from each group were randomly selected for further analysis. Data pertaining to the direct healthcare costs for these patients was analysed. Costs per investigation/intervention were obtained relating to hospital stay, outpatient care, operative interventions and investigations. Overall 26 patients were referred to our complex trauma service from other units over 6 months. A mean of £8,375 (6,163) per patient was recouped using current Service Level Agreements. This amounts to a £26,587 deficit per patient, or £1,394,905 per year assuming current referral rates. Those planning a service treating complex trauma must allow for the considerable costs involved and make provisions to recoup this from the referring Primary Care Trust

Motorcycle accident-related traffic accidents contribute significantly to the burden of orthopaedic injuries seen in the South African Healthcare system. Subsequent to the Covid-19 pandemic, there has been an increase in the number of delivery drivers on the roads of South Africa. Many of these delivery drivers have no formal employment contracts. We aim to describe the demographics and injury patterns in motorcyclists involved in time dependent delivery work in South Africa; and to quantify the cost to the state of their orthopaedic surgeries.

We performed a consecutive case series study at all of the hospitals draining the study region over the period of one year. Epidemiological, clinical and cost to hospital data was collected from medical records, digital radiographs, theatre invoices and a dedicated patient questionnaire.

Purpose. There is increasing evidence that primary fixation of displaced mid-shaft fractures of the clavicle results in superior short-term outcomes when compared to traditional non-operative methods. However, the results from published studies are limited to relatively short-term (one year or less) follow-up. Accurate data of longer follow-up is important for a number of reasons, including patient prognostication, counseling and care, the design of future trials, and the economic analysis of treatment. The purpose of this paper was to examine the results of the two year follow up of patients enrolled in a previously published randomized clinical trial of operative versus non-operative treatment of displaced fractures of the clavicle. Method. Using a comprehensive and standard assessment that included DASH (Disabilities of the Arm, Shoulder and Hand) and CSS (Constant Shoulder Scores) scores, we evaluated ninety-five patients of the original cohort of one hundred and thirty-two patients at two years following their injury. Results. Statistical analysis performed on the two year follow up data revealed that DASH and CSS scores remained essentially unchanged at two years post-injury compared to one year post-injury for both operative and non-operative groups (p>0.05). Additionally, outcome scores in the operative group remained superior to the non-operative group (DASH operative 4 +/− 7 versus DASH non-operative 11 +/− 20, p<0.014, CSS operative 97 +/− 4 versus CSS non-operative 92 +/− 14, p<0.012) at two years post-injury. Conclusion. The improvement in outcome seen with primary fixation of displaced clavicle fractures persists at two years but does not differ significantly from values seen after one year of follow-up, suggesting that clinically a steady state has been reached whereby outcome is unlikely to change with time. This has clinical, economic, and research implications

Purpose

Using utilities and other outcome data collected prospectively on all SPRINT patients and cost data collected from a sample of SPRINT patients, we compared reamed and unreamed intramedullary nailing using a cost-utility analysis.

The ability to calculate quality-adjusted life-years (QALYs) for degenerative cervical myelopathy (DCM) would enhance treatment decision making and facilitate economic analysis. QALYs are calculated using utilities, or health-related quality-of-life (HRQoL) weights. An instrument designed for cervical myelopathy disease would increase the sensitivity and specificity of HRQoL assessments. The objective of this study is to develop a multi-attribute utility function for the modified Japanese Orthopedic Association (mJOA) Score. We recruited a sample of 760 adults from a market research panel. Using an online discrete choice experiment (DCE), participants rated 8 choice sets based on mJOA health states. A multi-attribute utility function was estimated using a mixed multinomial-logit regression model (MIXL). The sample was partitioned into a training set used for model fitting and validation set used for model evaluation. The regression model demonstrated good predictive performance on the validation set with an AUC of 0.81 (95% CI: 0.80-0.82)). The regression model was used to develop a utility scoring rubric for the mJOA. Regression results revealed that participants did not regard all mJOA domains as equally important. The rank order of importance was (in decreasing order): lower extremity motor function, upper extremity motor function, sphincter function, upper extremity sensation. This study provides a simple technique for converting the mJOA score to utilities and quantify the importance of mJOA domains. The ability to evaluate QALYs for DCM will facilitate economic analysis and patient counseling. Clinicians should use these findings in order to offer treatments that maximize function in the attributes viewed most important by patients

While pre-soaking grafts in vancomycin has demonstrated to be effective in observational studies for anterior cruciate ligament reconstruction (ACLR) infection prevention, the economic benefit of the technique is uncertain. The primary aim of this study was to determine the cost-effectiveness of vancomycin pre-soaking during primary ACLR to prevent post-operative joint infections. The secondary aims of the study were to establish the breakeven cost-effectiveness threshold of the technique. A Markov model was used to determine cost effectiveness and the incremental cost effectiveness ratio of additional vancomycin pre-soaking compared to intravenous antibiotic prophylaxis alone. A repeated meta-analysis of nine cohort studies (Level III evidence) was completed to determine the odds ratio of infection with vancomycin pre-soaking compared to intravenous antibiotics alone. Estimated costs and transitional probabilities for further surgery were obtained from the literature. Breakeven threshold analysis was performed. The vancomycin soaking technique provides an expected cost saving of $600AUD per patient. There was an improvement in the quality-adjusted life years of 0.007 compared to intravenous antibiotic prophylaxis alone (4.297 versus 4.290). If the infection rate is below 0.023% with intravenous antibiotics alone or the additional intervention cost more than $1000AUD, the vancomycin wrap would no longer be cost-effective. For $30AUD, the vancomycin soaking technique provides a $600AUD cost saving by both reducing the risk of ACLR related infection and economic burden of infection. Treating septic arthritis represents a mean cost per patient of 6 times compared to that of the primary surgery. There has been no previous cost-effectiveness study of the vancomycin wrap technique. The vancomycin pre-soaking technique is a highly cost-effective method to prevent post-operative septic arthritis following primary ACLR

Traumatic rotator cuff injuries can be a leading cause of prolonged shoulder pain and disability, and contribute to significant morbidity and healthcare costs. Previous studies have shown evidence of socio-demographic disparities with these injuries. The purpose of this nationwide study was to better understand these disparities based on ethnicity, sex, and socio-economic status, in order to inform future healthcare strategies. Accident Compensation Corporation (ACC) is a no-fault comprehensive compensation scheme encompassing all of Aotearoa/New Zealand (population in 2018, 4.7 million). Using the ACC database, traumatic rotator cuff injuries were identified between January 2010 and December 2018. Injuries were categorized by sex, ethnicity, age and socioeconomic deprivation index of the claimant. During the 9-year study period, there were 351,554 claims accepted for traumatic rotator cuff injury, which totalled over $960 million New Zealand Dollars. The greatest proportion of costs was spent on vocational support (49.8%), then surgery (26.3%), rehabilitation (13.1%), radiology (8.1%), general practitioner (1.6%) and “Other” (1.1%). Asian, Māori (Indigenous New Zealanders), and Pacific peoples were under-represented in the age-standardized proportion of total claims and had lower rates of surgery than Europeans. Māori had higher proportion of costs spent on vocational support and lower proportions spent on radiology, rehabilitation and surgery than Europeans. Males had higher number and costs of claims and were more likely to have surgery than females. There were considerably fewer claims from areas of high socio-economic deprivation. This large nation-wide study demonstrates the important and growing economic burden of rotator cuff injuries. Indirect costs, such as vocational supports, are a major contributor to the cost suggesting improving treatment and rehabilitation protocols would have the greatest economic impact. This study has also identified socio-demographic disparities which need to be addressed in order to achieve equity in health outcomes

Robotic and navigated TKA procedures have been introduced to improve component placement precision for the purpose of improving implant survivorship and other clinical outcomes. Although numerous studies have shown enhanced precision in placing components, adoption of technology-assistance (TA) for TKA has been relatively slow. One reason for this has been the difficulty in demonstrating the cost-effectiveness of implementing TA-TKA systems and assessing their impact on revision rates. In this study, we aimed to use a simulation approach to answer the following questions: (1) Can we determine the distribution of likely reductions in TKA revision rates attributable to TA-TKA in an average US patient population? And, (2) What reduction in TKA revision rates are required to achieve economic neutrality?. In a previous study, we developed a method for creating large sets of simulated TKA patient populations with distributions of patient-specific factors (age at index surgery, sex, BMI) and one surgeon-controlled factor (coronal alignment) drawn from registry data and published literature. Effect sizes of each factor on implant survival was modeled using large clinical studies. For 10,000 simulated TKA patients, we simulated 20,000 TKA surgeries, evenly split between groups representing coronal alignment precisions reported for manual (±3°) and TA-TKA (±1.0°), calculating the patient-specific survival curve for each group. Extending our previous study, we incorporated the probability of each patient's expected survival into our model using publicly available actuarial data. This allowed us to calculate a patient-specific estimate of the Reduction in Lifetime Risk of Revision (RLRR) for each simulated patient. Our analysis showed that 90% of patients will achieve an RLRRof 1.5% or less in an average US TKA population. We then conducted a simplified economic analysis with the goal of determining the net cost of using TA-TKA per case when factoring in future savings by TKA revision rates. We assumed an average cost of revision surgery to be $75,000 as reported by Delanois (2017) and an average added cost incurred by TA-TKA to be $6,000 per case as reported by Antonis (2019). We estimate the net cost per TA-TKA case (CNet) to be the added cost per TA-TKA intervention (CInt), less the cost of revision surgery (CRev) multiplied by the estimated RLRR: CNet = CInt - CRev∗RLRR. We find that, under these assumptions, use of TA-TKA increases expected costs for all patients with an RLRR of under 8%. Based on these results, it appears that it would not be cost-effective to use TA-TKA on more than a small fraction of the typical US TKA patient population if the goal is to reduce overall costs through reducing revision risks. However, we note that this simulation does not consider other possible reported benefits of TA-TKA surgery, such as improved functional and pain outcome scores which may justify its use on other grounds. Alternative costs incurred by TA-TKA will be evaluated in a future study. To reach economic neutrality, TA-TKA systems either must reduce the added cost per intervention or increase RLRR by better addressing the root causes of revision

Prosthetic joint infections (PJI) are one of the most devastating complications of joint replacement surgery. They are associated with significant patient morbidity and carry a significant economic cost to treat. The management of PJI varies from antibiotic suppression, debridement, antibiotics, and implant retention (DAIR) procedures through to single/multiple stage revision procedures. Concerns have been raised recently in relation to the rising number of revision arthroplasty procedures that are being undertaken in relation to infection. This database aims to collect data on all PJIs that have been managed in the Australian Capital Territory (ACT) region. This will allow us to investigate the microbial trends, outcomes of surgical intervention and patient outcomes within our local population. This database will incorporate diagnostic, demographic, microbiological and treatment information in relation to local PJI cases. The data will be collated from the local infectious diseases database, hospital medical records, and where available the Australian Orthopaedic Association National Joint Replacement Registry Data. The first 100 cases of PJI were assessed. 76% were defined as being acute. 56% of the patients received antibiotics prior to their diagnosis however only 3% were culture negative. 89% were monomicrobial and 11% polymicrobial. The intended management strategy was a DAIR in 38% of patients and a 2-stage revision in 12% of cases. The intended management strategy was successful in 46% of the patients. The ACT is uniquely placed to analyze and create a local PJI database. This will allow us to guide further treatment and local guidelines in terms of management of these complex patients

Periprosthetic joint infections (PJIs) and osteosynthesis-associated infections (OSIs) present significant challenges in trauma and orthopaedic surgery, substantially impacting patient morbidity, mortality, and economic burden. This concern is heightened in patients with pre-existing comorbidities, such as diabetes mellitus, which are not always modifiable at presentation. A novel intraoperative strategy to prevent these infections is the use of Defensive Antibacterial Coating (DAC), a bio-absorbable antibiotic-containing hydrogel applied to implant surfaces at implantation, acting as a physical barrier to prevent infection. The purpose of this study is to assess the use of a commercially available hydrogel (DAC), highlighting its characteristics that make it suitable for managing PJIs and OSIs in orthopaedics and traumatology. Twenty-five patients who underwent complex orthopaedic procedures with intraoperative application of DAC between March 2022 and April 2023 at a single hospital site were included. Post-operative assessment encompassed clinical, laboratory, and radiographic examinations. In this study, 25 patients were included, with a mean age of 70 ± 14.77 years and an average ASA grade of 2.46 ± 0.78. The cohort presented an average Charleston Comorbidity score of 5.45 ± 2.24. The procedures included 8 periprosthetic fractures, 8 foot and ankle surgeries, 5 upper limb surgeries, and 4 elective hip and knee surgeries. Follow-up assessments at 6 weeks and 6 months revealed no evidence of PJI or OSI in any patients, nor were any treatments for PJI or OSI required during the interim period. DAC demonstrated efficacy in preventing infections in high-risk patients undergoing complex orthopaedic procedures. Our findings warrant further investigation into the use of DAC in complex hosts with randomized control trials

Since the advent of the COVID-19 pandemic, there has been a technologically based progression to almost every sector of society. This has led to an influx of e-hailing motorcycle drivers (online based consumable transportation platforms) and thus an increase in road traffic accidents. This group experiences an abundance of Orthopaedic related trauma with a considerable economic burden. Therefore, the study aimed to determine the incidence of this study group as well as quantify the severity and cost implications thereof for the sake of public health and epidemiology. This was an observational study whereby a prospective cohort analysis was respectively conducted at a single centre to determine the incidence, of the study group, over a seven-month period. The study included any e-hailing motorcycle driver who sustained Orthopaedic related trauma, whilst on duty, within the catchment area whereas all other patients were excluded and used as a comparator. A descriptive statistical analysis was done to further delineate the severity of injury by comparing the type of injury, anatomical location injured, and management plan incurred. A total of 5096 individuals experienced Orthopaedic related trauma with 60 individuals (1.18%) being e-hailing motorcyclists who sustained injury whilst on duty. The incidence being 118 per 10000 patients. Further analysis revealed that 78.33% of the population experienced fractures or dislocations with 52.31% of these injuries requiring surgical intervention. The Upper limb (53.85%) and Lower limb (43.08%) were the most affected anatomical locations. The Orthopaedic care for this population group places a meaningful burden on the South African Health sector. These drivers work in unsafe environments and sustain high energy impacts, yet very little oversight exists. Therefore, continued research with new regulations needs to be drafted, looking into vehicle safety, working conditions, operative hours, and the need for public awareness

Fragility fractures are an emerging healthcare problem in Sub-Saharan Africa and hip fractures (HFs) are associated with high levels of morbidity, prolonged hospital stays, increased healthcare resources utilization, and mortality. The worldwide average healthcare cost in the first-year post HF was US$43,669 per patient in a 2017 systematic review, however there are no studies quantifying fracture-associated costs within SSA. We estimated direct healthcare costs of HF management in the South African public healthcare system. We conducted a prospective ingredients-based costing study in 200 consecutive consenting HF patients to estimate costs per patient across five regional public sector hospitals in KwaZulu-Natal (KZN). Resource use including staff time, consumables, laboratory investigations, radiographs, operating theatre time, surgical implants, medicines, and inpatient days were collected from presentation to discharge. Counts of resources used were multiplied by relevant unit costs, estimated from KZN Department of Health hospital fees manual 2019/20, in local currency (South African Rand, ZAR). Generalised linear models were used to estimate total covariate adjusted costs and cost predictors. The mean unadjusted cost for HF management was ZAR114,179 (95% CI; ZAR105,468–125,335). The major cost driver was orthopaedics/surgical ward costs ZAR 106.68, contributing to 85% of total cost. The covariate adjusted cost for HF management was ZAR114,696 (95% CI; ZAR111,745–117,931). After covariate adjustment, total costs were higher in patients operated under general anaesthesia compared to surgery under spinal anaesthesia and no surgery. Direct healthcare costs following a HF are substantial: 58% of the gross domestic per capita (US$12,096 in 2020), and six-times greater than per capita spending on health (US$1,187 in 2019) in SA. As the population ages, this significant economic burden to the health system will increase. Further research is required to evaluate direct non-medical, and the indirect costs incurred post HF

Timely and competent treatment of paediatric fractures is paramount to a healthy future working population. Anecdotal evidence suggests that children travel greater distances to obtain care compared to adults causing economic and geographic inequities. This study aims to qualify the informal regionalization of children's fracture care in Ontario. The results could inform future policy on resource distribution and planning of the provincial health care system. A retrospective cohort study was conducted examining two of the most common paediatric orthopaedic traumatic injuries, femoral shaft and supracondylar humerus fractures (SCH), in parallel over the last 10 years (2010-2020) using multiple linked administrative databases housed at the Institute for Clinical Evaluative Sciences (ICES) in Toronto, Ontario. We compared the distance travelled by these pediatric cohorts to clinically equivalent adult fracture patterns (distal radius fracture (DR) and femoral shaft fracture). Patient cohorts were identified based on treatment codes and distances were calculated from a centroid of patient home forward sortation area to hospital location. Demographics, hospital type, and closest hospital to patient were also recorded. For common upper extremity fracture care, 84% of children underwent surgery at specialized centers which required significant travel (44km). Conversely, 67% of adults were treated locally, travelling a mean of 23km. Similarly, two-thirds of adult femoral shaft fractures were treated locally (mean travel distance of 30km) while most children (84%) with femoral shaft fractures travelled an average of 63km to specialized centers. Children who live in rural areas travel on average 51km more than their adult rural-residing counterparts for all fracture care. Four institutions provide over 75% of the fracture care for children, whereas 22 institutions distribute the same case volume in adults.?. Adult fracture care naturally self-organizes with proportionate distribution without policy-directed systemization. There is an unplanned concentration of pediatric fracture care to specialized centers in Ontario placing undue burden on pediatric patients and inadvertently stresses the surgical resources in a small handful of hospitals. In contrast, adult fracture care naturally self-organizes with proportionate distribution without policy-directed systemization. Patient care equity and appropriate resource allocation cannot be achieved without appropriate systemization of pediatric fracture care
