Predicting In-Hospital Mortality in Critical Orthopaedic Trauma Patients with Sepsis Using Machine Learning Models.

Purpose: This study aims to establish and validate machine learning-based models to predict death in hospital among critical orthopaedic trauma patients with sepsis or respiratory failure.Methods: This study collected 523 patients from the Medical Information Mart for Intensive Care database. All patients were randomly classified into a training cohort and a validation cohort. Six algorithms, including logistic regression (LR), extreme gradient boosting machine (eXGBM), support vector machine (SVM), random forest (RF), neural network (NN), and decision tree (DT), were used to develop and optimize models in the training cohort, and internal validation of these models were conducted in the validation cohort. Based on a comprehensive scoring system, which incorporated ten evaluation metrics, the optimal model was obtained with the highest scores. An artificial intelligence (AI) application was deployed based on the optimal model in the study.Results: The in-hospital mortality was 19.69%. Among all developed models, the eXGBM had the highest area under the curve (AUC) value (0.951, 95%CI: 0.934-0.967), and it also showed the highest accuracy (0.902), precise (0.893), recall (0.915), and F1 score (0.904). Based on the scoring system, the eXGBM had the highest score of 53, followed by the RF model (43) and the NN model (39). The scores for the LR, SVM, and DT were 22, 36, and 17, respectively. The decision curve analysis confirmed that both the eXGBM and RF models provided substantial clinical net benefits. However, the eXGBM model consistently outperformed the RF model across multiple evaluation metrics, establishing itself as the superior option for predictive modeling in this scenario, with the RF model as a strong secondary choice. The SHAP analysis revealed that SAPS II, age, respiratory rate, OASIS, and temperature were the most important five features contributing to the outcome.Conclusions: This study develops an artificial intelligence application to predict in-hospital mortality among critical orthopaedic trauma patients with sepsis or respiratory failure.

Coiling of echogenic perineural catheters with integral stylet: A proof-of-concept randomized control trial in a sciatic nerve block simulator and a pilot study in orthopaedic-trauma patients.

We investigated a technique that facilitates the coiling of a regular straight catheter (with integral stylet) behind the sciatic nerve in an ultrasound (US) regional anaesthesia simulator, and then applied our findings to a series of orthopedic-trauma patients. We conducted a randomized study of two methods of perineural catheter advancement in a sciatic nerve block Blue Phantom simulator. Two groups of twenty catheters each (method A and method B) were evaluated under real-time ultrasound imaging. The needle in-plane/nerve in-short-axis technique was applied. In method A the catheter was advanced beyond the needle tip with the integral stylet extending along its entire length; in method B the catheter was advanced after its integral stylet was retracted by 6 cm, thus providing flexibility to the catheter's distal end. Additionally, to assess the procedural effectiveness of method B coiling technique, a pilot study was conducted examining 25 perineural catheters coiled underneath the sciatic nerve in trauma-orthopaedic patients to document any catheter tip displacement from their initial position (for 36 hours postoperatively). In the simulation study, method B led to a significantly higher percentage (18/20:90%) of coiled catheters than method A (3/20:15%). Two coiled catheters of method B were found kinked/obstructed. In our patients, after catheter insertion, the distal end of 2/25 (8%) coiled catheters was obstructed. One perineural catheter was dislodged. For the remaining 22 (88%) catheters, ultrasound imaging demonstrated that local anaesthetic infusion made contact with the sciatic nerve, indicating no displacement of the catheter's distal end postoperatively. Regular straight perineural catheters can be coiled if their integral stylet is partially retracted. This coiling method offers extra catheter length adjacent to the nerve structure which potentially mitigates catheter tip displacement. clinicaltrials.gov, registration No: NCT06568510, 23/08/2024, registration URL: https://clinicaltrials.gov/study/NCT06568510?intr=coiling%20of%20echogenic%20sciatic%20nerve&rank=1#study-overview.

Cell-free mitochondria are detected in high concentrations in the plasma of orthopedic trauma patients.

Trauma and surgery can derange inflammatory and hemostasis responses, potentially leading to multiple organ failure. Mitochondrial damage-associated molecular patterns are known to be part of the pathomechanism, but their exact origin remains uncertain. Recently, intact mitochondria were detected in healthy individuals' peripheral blood, which suggested a potential role in inflammation. In this case-control study, we quantitated cell-free mitochondria in the blood of healthy subjects (n = 4) and trauma patients (n = 25) and assessed their relationship with patient demographics, injury and shock severity, markers of tissue injury, inflammation, and blood transfusions. Blood samples were collected before and after major orthopedic trauma surgery, and cell-free mitochondria were quantified using flow cytometry, targeting the outer mitochondrial membrane protein, TOMM70. Mitotracker Deep Red staining was used to assess mitochondrial membrane potential. Trauma patients had significantly more cell-free mitochondria in their plasma compared with healthy controls, with highest counts immediately after surgery. The number of cell-free mitochondria decreased by day 5 postoperatively. Trauma patients exhibited a higher proportion of active cell-free mitochondria compared with healthy controls, especially immediately after surgery, and this proportion correlated with tissue injury markers. Associations were also found with acute thrombocytopenia, Denver multiple organ failure score, and transfusion of fresh frozen plasma and cryoprecipitate. Our findings indicate that the mere high number of cell-free mitochondria in the circulation of trauma patients is not necessarily pro-inflammatory, but their active status is associated with more severe secondary tissue injury. The natural history of cell-free mitochondria in trauma needs to be characterized, including their potential cause-effect relationship with major postinjury complications.

Evaluation Of The Frailty Index And Thiol-Disulphide Levels In Geriatric Orthopedic Injuries

Backround: One of the concepts recently discussed about old age is frailty. Frailty was found to be important in determining weakness and indulgence in the elderly. Frail older people are more likely to fall and experience related orthopedic trauma. Free oxygen radicals are known to cause oxidative stress in trauma patients. The aim of this study is to report the levels of frailty and thiol disulphide homeostasis and related factors in patients with geriatric orthopedic injury who presented to the emergency department.Methods: This study included 82 patients aged 65 and over who were admitted to the Emergency Department of XXX City Hospital in 2020 due to orthopedic trauma, and 38 people who presented for other reasons in a control group. FRAIL Frailty scale was used to evaluate frailty. In samples from patients' venous blood, native thiol and total thiol were analyzed.Results: The average age of the patients was78.48 ±7.86(min: 65-max: 99). Of the patients, 30.8% were in the prefrail group and56.7% were in the frail group. In patient and control group comparisons, total thiol values ​​in the patient group were significantly lower, and disulphide, ischemia-modified albumin, index 1 and index 2 values ​​were significantly higher in the patient group compared with the control group. There were significantly more prefrail individuals(41.5%) among orthopedic trauma patients, and frail individuals (81.6%) in the control group. There was a significant weak negative correlation between body mass index and native thiol and total thiol values.Conclusion: Oxidative stress is increased in patients with geriatric orthopedic injuries.

There is no correlation between differences in adverse events and differences in patient-reported outcome measures in orthopaedic trauma randomized controlled trials: A systematic review

IntroductionA recovery without adverse events is a top priority of orthopaedic trauma patients, however many randomized controlled trials (RCTs) are only powered to detect a difference in patient-reported outcome measures (PROMs). While it may be assumed that differences in major adverse event rates between treatment groups will result in differences in PROMs, this has not been established. The purpose of this study was to perform a systematic review of RCTs to evaluate if differences in these outcomes were correlated. MethodsA systematic search was conducted of online databases to identify RCTs in orthopaedic trauma fracture management that reported both major adverse events and PROMs. Adverse events included secondary surgeries or complications that could negatively affect long-term outcomes (nonunion, chronic regional pain syndrome, etc.). The correlation between a difference (p < 0.05) in adverse events and a difference in PROMs was assessed. ResultsThe systematic review yielded 30 RCTs involving 6,769 patients. The primary outcome was a continuous PROM in 70.0 % (21/30). A difference in major adverse events was reported in 23.3 % (7/30) and a difference in PROMs was reported in 6.7 % (2/30). Studies reporting a difference in adverse events, compared to those that did not, were not more likely to report a difference in PROMs (14.3 % (1/7) vs. 4.3 % (1/23); p = 0.42). ConclusionsThere was no correlation between differences in adverse event rates and differences in PROMs in orthopaedic trauma RCTs. Investigators should consider powering studies to detect differences in the major adverse events that both patients and surgeons wish to avoid. Level of evidenceLevel I

ThP7.10 - Perioperative Temperature in Relation to Theatre Temperature in Orthopaedic Trauma Patients in a District Hospital in NHS

Abstract Aim To understand the relation between intraoperative hypothermia and theatre temperature in Orthopaedic trauma list. Method Prospective analysis of patients listed in the trauma list at a busy district general hospital in NHS. The data collected included duration of surgery, preoperative temperature, pre induction temperature, intra-operative, post procedure, temperature in recovery and temperature post recovery, and mean ambient theatre temperature. Statistical calculations were performed on StatsDirect3 software. Results A total of 100 patients were included in the study from 1 Aug 2023 to 30 September 2023. Intraoperative hypothermia (core body temperature &amp;lt;= 36) was 21%. Preoperative temperature (p=0.033) and preinduction temperature (p&amp;lt;0.001) was statistically significant factor in influencing the intraoperative temperature. Theatre temperature was an independent predictor of intraoperative hypothermia on regression analysis (p&amp;lt;0.001). Conclusions Theatre temperature of 19.5 to 20.5 °C results in a core body intraoperative temperature of 36.3 to 37.3°C. Temperatures below 19.5 results in higher incidence of hypothermia. Preinduction temperature of 36.4°C results in intraoperative temperature of 36°C and a preinduction temperature of 37.1°C leads to intraoperative temperature of 36.7°C. This indicates that preoperative warming as well as a theatre temperature of 19.5 to 20.5 °C will help in reduction of the intraoperative hypothermia.

Prevalence of Vitamin D Deficiency in Orthopedic Trauma Patients: A Cross-Sectional Survey From a Tertiary Care Trauma Center.

Background Vitamin D deficiency is prevalent globally, with potential consequences for bone health and trauma outcomes. This study aimed to assess the prevalence of vitamin D deficiency in orthopedic trauma patients and investigate its correlation with various demographic and injury-related factors. Methodology A cross-sectional investigation was undertaken at a tertiary care center. An evaluation of serum 25-hydroxyvitamin D3 levels was conducted on 124 individuals, aged 20 to 70 years, who were hospitalized with orthopedic injuries. Demographic information, the injury method, the bone involvement pattern, and socioeconomic status were documented. Statistical analysis was employed to evaluate the correlations between vitamin levels D and these variables. Results The overall prevalence of vitamin D deficiency was 54 (43.6%) cases, with nine (7.3%) cases exhibiting severe deficiency and 45 (36.3%) cases exhibiting moderate deficiency. Higher rates of deficiency were associated with lower socioeconomic status (p = 0.044) and low-velocity trauma (p = 0.037). No significant association was found with age, sex, or residence. Interestingly, patients with multiple fractures were more prone to deficiency compared to those with single fractures. Conclusions This survey revealed a significant vitamin D deficiency among orthopedic trauma patients. Factors such as socioeconomic status and the nature of the injury emerged as significant risk factors. While conducting routine vitamin D assessments might pose challenges in developing nations, consistent supplementation could prove advantageous in enhancing fracture healing and overall health outcomes among this demographic. There is a call for future research to delve deeper into the role of vitamin D in trauma management and refine supplementation strategies.

Special Considerations in the Orthopaedic Trauma Patient: Curbing Negative Social Behaviors

Optimizing the orthopaedic trauma patient for surgical intervention presents unique challenges. Due to the acute nature of musculoskeletal injuries and time constraints for treatment, there is a limited window for overall patient comorbidity optimization prior to surgical fracture repair. Certain social behaviors including tobacco use, excessive alcohol consumption, and inappropriate opioid medication usage can have a negative impact on wound and fracture healing. Curbing such negative social behaviors can have a positive outcome on patients who are affected by musculoskeletal trauma. Addressing these challenging issues, via available resources, can have a significant impact on recovery after sustaining orthopaedic trauma. A tactical approach focused on relationship building with patients and their families as well as highlighting strategies to curb negative social behaviors is presented involving a patient with an infected tibial nonunion.

Hyperglycemia in Orthopaedic Trauma Patients: Implications, Management, and Future Directions

Physiologic stress-induced hyperglycemia (SIH) significantly impacts patient outcomes in both non-diabetic and diabetic individuals following orthopaedic trauma. This review synthesizes current literature on SIH's effects, highlighting its association with increased surgical site infections (SSI), extended hospital stays, wound complications, nonunion, need for revision surgery, and mortality. Non-diabetic patients with SIH face worse outcomes compared to euglycemic patients, including a higher risk of deep infections and systemic complications. Diabetic patients experience exacerbated hyperglycemia during trauma, leading to poor wound healing and heightened infection risk. Effective glycemic control, through preoperative optimization, intraoperative monitoring, and postoperative management, is crucial for improving outcomes. Special considerations are discussed for the geriatric population, who are particularly vulnerable to SIH-induced morbidity and mortality. Future directions emphasize developing tailored glycemia management algorithms, utilizing continuous monitoring systems, and fostering multidisciplinary collaboration to optimize care for orthopaedic trauma patients.

Improving Patient Recall Following Operative Orthopaedic Trauma.

Orthopaedic trauma patients may experience poor recall regarding their injury and treatment, impairing postoperative outcomes. We sought to evaluate the impact of a standardized postoperative educational protocol on patient recall, adherence to the treatment plan, and satisfaction. Two hundred and twenty adult, English-speaking patients with surgically treated lower-extremity fractures were prospectively included. One hundred and ten patients in the educational intervention cohort met with a non-physician study member after surgery but before hospital discharge. They were given a written questionnaire evaluating knowledge of key aspects of their injury and treatment plan. For incorrectly answered questions, the study team member told the patient the correct answer (e.g., "No, you broke your tibia."). Immediately after, the patient was verbally asked the question again (e.g., "Which bone did you break?"), repeating the process until the answer was correct. The 110 patients in the control cohort did not receive this "teach-back" protocol. During their first postoperative appointment, all 220 patients completed a follow-up questionnaire assessing recall, adherence to the treatment plan, and satisfaction. The control cohort correctly answered 64% of recall-oriented questions versus 89% in the intervention cohort (p < 0.001). Eighty-two percent of control patients versus 89% patients in the intervention cohort adhered to postoperative weight-bearing restrictions (p = 0.09). Eighty-four percent of controls adhered to their deep venous thrombosis prophylaxis regimen versus 99% of the intervention cohort (p < 0.001). On a 5-point Likert scale, controls were less satisfied with their overall orthopaedic care compared with patients in the intervention cohort (mean of 4.38 ± 0.84 versus 4.54 ± 0.63 points; p = 0.02), although this difference was less than the minimal clinically relevant difference of 10% that was defined at study onset. On propensity score-weighted multivariable analysis, receipt of the postoperative educational intervention was the only modifiable factor associated with improvement in patient recall (26% improvement [95% confidence interval, 20% to 31%]; p < 0.001). Some orthopaedic trauma patients' nonadherence to surgeon recommendations and dissatisfaction with care may be mitigated by postoperative education. This standardized postoperative educational protocol improves orthopaedic trauma patients' recall, adherence to their treatment plan, and satisfaction in a manner requiring minimal time.

Relationship between GPS-based community mobility data and orthopedic trauma admissions during the COVID-19 pandemic in Austria: amulticenter analysis.

The main objective of this study was to examine the relationship between mobility patterns during the coronavirus disease 2019 (COVID-19) pandemic and orthopedic trauma patients in Austria. Utilizing global positioning system (GPS)-based mobility data, the attempt was to assess both the impact of COVID-19 lockdowns on reducing orthopedic trauma patients and the degree of compliance to the imposed movement restrictions. This retrospective analysis included all patients (283,501) treated at 3 major levelI trauma centers in Austria. Analyzed time periods were 1 January 2019 to 8 February 2021. Freely available GPS-based mobility data from Google and Apple Inc. was gathered. Amoderate to strong correlation between the cumulative average outpatients and the assessed mobility index was observed for all cities (Google: r = 0.70 p < 0.001, 95% confidence interval, CI: 0.67-0.73; Apple: r = 0.64 p < 0.001, 95% CI: 0.61-0.67). Asignificant linear regression equation was found for Vienna (adjusted r2 = 0.48; F(1, 350) = 328,05; p < 0.01). During the first lockdown there was adrastic decline in mobility (up to -75.36%) and in numbers of orthopedic trauma outpatients (up to -64%, from 153 patients/day 2019 to 55patients/day 2020) in comparison to the prepandemic era. The decline diminished as time passed. Analyses of GPS-based mobility patterns show acorrelation with trauma patient numbers. These findings can be used to develop prediction models, leading to better resource planning and public health policy, enhancing patient care and cost-effectiveness, especially in the event of future pandemics. Furthermore, the results suggest that compliance to mobility restrictions decreased over time during the COVID-19 pandemic, resulting in increased mobility and trauma patients.

Nutritional Prehabilitation in the Orthopaedic Trauma Patient

Nutrition is a modifiable factor which should be optimized in the surgical patient. Peri-operative programs, such as “Strong for Surgery”, identify patients with protein malnutrition and provide resources for adequate feeding in the peri-operative period. The Orthopedic Trauma patient benefits from this approach to encourage surgical wound healing, avoidance of septic complication, uneventful bone union, and successful rehabilitation. Acute orthopedic injuries requiring prompt intervention should be assessed for protein malnutrition and receive supplementation when necessary post-operatively. Patients with peri-articular fracture managed staged or for post-traumatic cases, nutrition should be assessed pre-operatively and addressed prior to definitive surgical reconstruction.

Metagenomic changes in response to antibiotic treatment in severe orthopedic trauma patients

We investigated changes in microbiome composition and abundance of antimicrobial resistance (AMR) genes post-antibiotic treatment in severe trauma patients. Shotgun sequencing revealed beta diversity (Bray-Curtis) differences between 16 hospitalized multiple rib fractures patients and 10 age- and sex-matched controls (p= 0.043), and between antibiotic-treated and untreated patients (p= 0.015). Antibiotic-treated patients had lower alpha diversity (Shannon) at discharge (p= 0.003) and 12-week post-discharge (p= 0.007). At 12weeks, they also exhibited a 5.50-fold (95% confidence interval [CI]: 2.86-8.15) increase in Escherichia coli (p= 0.0004) compared to controls. Differential analysis identified nine AMRs that increased in antibiotic-treated compared to untreated patients between hospital discharge and 6 and 12weeks follow-up (false discovery rate [FDR]<0.20). Two aminoglycoside genes and a beta-lactamase gene were directly related to antibiotics administered, while five were unrelated. In trauma patients, lower alpha diversity, higher abundance of pathobionts, and increases in AMRs persisted for 12weeks post-discharge, suggesting prolonged microbiome disruption. Probiotic or symbiotic therapies may offer future treatment avenues.

Optimizing the Orthopaedic Trauma Patient- Staged Management

Staged management of orthopedic trauma is employed to promote best outcomes and avoid known complications associated with acute definitive fracture reconstruction. Fracture in the setting of polytrauma is often initially managed with temporizing methods to allow for both optimization of the host and local soft tissue environment. Damage control orthopedics has promoted this strategy to delay definitive care of orthopaedic injuries based on the patient's level of resuscitation/inflammatory state. Further, staged care of peri-articular fracture respects the already traumatized soft tissue envelope in an effort to decrease the risk of infamous complications such as infection and fracture nonunion. Typically, external fixation is utilized in staged management and host optimization is performed in the “waiting period.”

Validation of Patient-Reported Outcome Measurement Information System for Detection of Posttraumatic Stress in Children and Adolescents Following Procedures for Acute Orthopaedic Trauma.

The efficiency and validity of the Patient-Reported Outcomes Measurement Information System (PROMIS) surveys were determined for pediatric orthopaedic trauma patients with posttraumatic stress disorder (PTSD) symptoms in a clinic setting. Prospective cohort study. Single-institution, Level I trauma center. All consecutive children aged 8-18 years undergoing procedures or surgery for orthopaedic trauma. The convergent, divergent, and discriminant validity of the PROMIS Anger and Anxiety computerized adaptive tests (CATs) were evaluated and compared with the previously validated Child PTSD Symptom Scale (CPSS). The efficiency in time to completion of the outcome measures was compared between the CPSS and PROMIS surveys. Cutoffs for increased likelihood of PTSD were established for the PROMIS questionnaires. A total of 233 subjects were included in this study (mean age 13.1 years with SD 2.8 years, 71% male). The majority (51%) of injuries were related to sports, and most (60%) involved the upper extremity. Of those included, 41 patients had high levels of PTSD symptoms on the CPSS (18%; 95% CI, 13.1-23.2%). The CPSS took 182 (interquartile range [IQR] 141-228) seconds versus 52 (IQR 36-84) and 52 (IQR 36-70) seconds for PROMIS Anger and Anxiety CATs, respectively. Convergent validity showed patient scores on both PROMIS instruments significantly correlated with CPSS scores (Anger: P < 0.001, r = 0.51; Anxiety: P < 0.001, r = 0.41). Neither PROMIS score correlated with University of California Los Angeles Activity Score (Anger: r = -0.26; Anxiety: r = -0.22), a functional outcome measure, demonstrating divergent validity. Both PROMIS instruments sufficiently discriminated across PTSD risk groups (Anger P < 0.001; Anxiety P < 0.001). A score of at least 53 on PROMIS Anger or at least 48 on PROMIS Anxiety indicated an increased likelihood of PTSD risk. PROMIS Anger and Anxiety CATs are efficient and valid for evaluating posttraumatic stress in children following orthopaedic trauma procedures. Diagnostic Level I.

Multidisciplinary management of orthopaedic trauma - are we adhering to the guidelines?

A multidisciplinary team (MDT) approach to polytrauma patients minimises morbidity and mortality. This project assesses the extent to which British Orthopaedic Association Standards for Trauma guidelines for the management of the frail Orthopaedic patient are currently being met. A retrospective analysis was performed of all Trauma and Orthopaedic patients in multiple medical institutions over a 2-week capture period from 1 March 2022 until 14 March 2022 inclusive. Data collected included age, sex, injury, length of stay and dates of speciality input. A total of 1,050 patients were included from 27 hospitals. The median age was 80 years, with 560 (53.3%) of all fractures being neck of femur fractures. Of the 1,050 patients, 870 (82.9%) were managed operatively. The median number of different speciality involvements was 3; 645 (61.4%) had an orthogeriatric (OG) review. In major trauma centres (MTC), 93.3% had OG input, compared with 66.3% in non-MTC. The speciality with the greatest input was Radiology, with Plastics having the lowest input. A standardised MDT approach is needed to optimise care and recovery in orthopaedic trauma patients. The difference in results regarding speciality involvement is substantial and needs to be addressed to minimise disparities in care received by this vulnerable cohort of patients.

Bridge Versus Volar Plating Distal Radius Fractures in Patients With Concomitant Lower-Extremity Fractures

Our objective was to determine if patients with a distal radius fracture and concomitant lower-extremity fracture benefit from bridge plating when compared with volar plating. We conducted a retrospective cohort study evaluating distal radius fractures fixated by bridge or volar plating in orthopedic trauma patients with a concomitant lower-extremity fracture. Patients were prescribed a platform walker and followed for gait aid use and both upper and lower-extremity fracture-related outcomes. Differences in platform walker use, radiographic findings, and rates of complications for both distal radius and lower-extremity fractures were comparable between groups. Although more studies are needed, it appears that this cohort of patient's ability to mobilize using a gait aid is similar, regardless of the distal radius fracture fixation method. A concomitant lower-extremity fracture should not necessarily indicate bridge plating over volar plate fixation. Therapeutic Study IV.

Pre-injury methamphetamine use is associated with increased length of hospital stay in rural orthopaedic trauma patients

ObjectivesThe primary focus of this study is to determine if rural methamphetamine positive patients experience longer hospital length of stays compared to urban methamphetamine positive patients following an orthopaedic trauma. MethodsPatients presenting with traumatic orthopaedic injuries and urine drug screen were categorized into urban, suburban, and rural cohorts found in the Rural Urban Commuting Area codes based on home residence zip codes. Demographic, injury, hospital stay, and follow-up data were collected from the medical records. Comparisons between cohorts were determined by Chi square, Fisher exact, unpaired t-Tests, or ranked sum tests. DesignA retrospective cohort analysis. SettingAcademic Level I Trauma Center. Patient selection criteriaPatient records were examined between January 2013 to January 2023 for a traumatic orthopaedic injury and a urine drug screen result at the time of presentation to an academic Level I trauma center. Outcome measures and comparisonsMethamphetamine use status, patient age at time of admission, sex, marital status, insurance status, home zip code, orthopaedic injury location, complications, if the patient underwent surgery for orthopaedic injuries, admission date, discharge date, and discharge location were measured. Results249 patients met inclusion criteria for this analysis. Methamphetamine positive patients are significantly more likely to be younger, more likely to have surgery for orthopaedic injuries, experience a medical complication, or be discharged to home or a rehabilitation facility compared to methamphetamine negative patients. Urban patients experienced a shorter length of stay compared to suburban and rural patients, regardless of methamphetamine use status. Patients with Medicare, military, workers compensation, or commercial insurance are significantly more likely to attend follow-up appointments than patients with Medicaid or self-pay. ConclusionsMethamphetamine positive patients overall do not experience a longer length of hospital stay compared to methamphetamine negative patients. Rural methamphetamine positive patients experience a longer length of hospital stay compared to urban methamphetamine positive patients.

Clinical Audit to Assess Orthogeriatrician Input to the Management of Elderly Trauma Patients.

The primary objective of this study is to assess the adherence of our department to the British Orthopaedic Association's Standards for Trauma and Orthopaedics (BOAST) guidelines for "the care of the older or frail orthopaedic trauma patient" and the results of this adherence on clinical patient outcome measures. This was a clinical audit. All ≥65-year-olds admitted to the orthopaedic department with a fragility fracture between 8 September 2022 and 8 March 2023 with a length of stay (LOS) of >72 hours were included. Patients were stratified into hip fracture (HF) and non-hip fracture (NHF) patients. A further similar cohort of NHF admissions between 8 March and 8 May 2023 was added to the data. The adherence of both cohorts to the national guidelines was recorded. Primary outcome measures of each cohort were recorded such as LOS and patient mortality. Data from 70 patients was collected. HF patients adhered to the guideline 79.4% of the time (31/39 patients) compared to NHF patients at only 19.3% of the time (6/31 patients) (p<0.001). Further, on average, HF patients were seen by an orthogeriatrician 15 times compared to just five times for NHF patients during their hospital stay (p<0.001). No significant difference in LOS or in mortality at 30 days post-admission was observed. Medical orthogeriatric care is unequal despite similar LOS and mortality between both cohorts; thus, increasing orthogeriatrician input in NHF patients may lead to better patient outcomes for these patients.
