Uptake of telehealth services by people recovering from road trauma in Victoria, Australia

Introduction In recent years, injury insurers in Australia have introduced compensation cover for services delivered via telehealth. The aim of this study was to investigate the uptake of telehealth services by people recovering from road trauma in Victoria, Australia, and the characteristics of participants accessing these services. Methods All Victorian State Trauma Registry and Victorian Orthopaedic Trauma Outcomes Registry cases, aged ≥16 years, who sustained transport-related injury from March to August 2020, and were linked with the Transport Accident Commission claims dataset, were included in this registry-based cohort study. The primary outcome was the uptake of services accessed in-person and via telehealth. Results Within 12 months of injury, 413 participants accessed 93,035 services, with 1432 of these via telehealth (1.5%). Seventy-five percent of family counselling, 26% of psychology and 7% of medical consultations were accessed via telehealth. For telehealth users, a greater proportion had worked/studied prior to injury, met major trauma criteria, and were discharged to inpatient rehabilitation, compared to non-users. For participants with no telehealth use, a greater proportion were discharged home, and were classified as ‘rapid recovery’ clients. Conclusions While telehealth uptake was low during the study period, it was accessed by people with more severe injuries. There was also greater telehealth uptake during some of Victoria's strictest COVID-19 lockdowns. Telehealth may continue to be an appealing option for medical and psychological services into the future, and may assist with return to work following transport injury.

Outcomes of rectal cancer treatment in rural Australia and New Zealand: analysis of the bowel cancer outcomes registry.

The demographics and geography of Australia and New Zealand (ANZ), with few metropolitan centres and vast, sparsely populated rural areas, represent a challenge to providing equal care to all patients. This study aimed to compare rectal cancer care at rural and urban hospitals in ANZ. From the Bowel Cancer Outcomes Registry (BCOR, formerly known as the Bi-National Colorectal Cancer Audit; BCCA), rectal cancer patients treated between 2007 and 2020 were compared based on hospital location (urban versus rural). Propensity-score matching was performed to correct for differences in baseline characteristics between groups. A total of 9385 rectal cancer patients were identified from the BCOR: 1329 (14.2%) were treated at rural hospitals and 8056 (85.8%) at urban hospitals. Propensity-score matching resulted in 889 patients in each group, matched for age, ASA score, hospital type (public/private), tumour height from the anal verge, and pre-treatment cT- and cAJCC-stage. Rural patients had fewer pre-treatment MRIs (67.9% versus 74.7%; P = 0.002), and underwent less neoadjuvant therapy (44.7% versus 50.9%; P = 0.01). Rural patients underwent fewer ULARs (39.4% versus 45.6%; P = 0.03), and fewer anastomoses were formed (67.9% versus 74.4%; P = 0.05). CRM rates and postoperative AJCC stages (P = 0.19) were similar between groups (P = 0.87). Fewer rural patients received adjuvant chemotherapy (37.8% versus 43.3%; P = 0.02). There are significant differences in pre-treatment MRI rates, (neo)adjuvant treatment rates and surgical procedures performed between rectal cancer patients treated at rural and urban hospitals in ANZ, while CRM rates and postoperative AJCC stages are similar.

Two-Year Outcomes of Primary Arthroscopic Surgery in Patients with Femoroacetabular Impingement: A Comparative Study of Labral Repair and Labral Reconstruction.

Labral repair has become the preferred method for the arthroscopic treatment of acetabular labral tears that are associated with femoroacetabular impingement (FAI) resulting in pain and dysfunction. Labral reconstruction is performed mainly in revision hip arthroscopy but can be utilized in the primary setting for absent or calcified labra. The purpose of this study was to compare the minimum 2-year patient-reported outcomes (PROs) and risk of revision or conversion to arthroplasty between primary labral reconstruction and primary labral repair. Patients with FAI who underwent primary hip arthroscopy with labral repair or reconstruction performed by the senior author between 2006 and 2018 were identified from a prospectively enrolled patient outcome registry. Exclusion criteria included confounding injuries, dysplasia, prior ipsilateral hip surgery, or a joint space of <2 mm. Patients who were 18 to 80 years old were eligible for inclusion. Multiple regression with inverse propensity score weighting was conducted to estimate the average treatment effect in the treated (ATT) for labral reconstruction versus labral repair with respect to postoperative PROs and the likelihood of subsequent surgery (revision hip arthroscopy or conversion to arthroplasty). PRO end points included the Hip Outcome Score Activities of Daily Living subscale (HOS-ADL), modified Harris hip score, Western Ontario and McMaster Universities Osteoarthritis Index total score (WOMAC), 12-Item Short Form Health Survey Physical Component Summary score (SF-12 PCS), and patient satisfaction. A total of 150 hips undergoing primary labral reconstruction and 998 hips undergoing primary labral repair were included. The median follow-up time was 5.3 years in the reconstruction group and 5.8 years in the repair group. Compared with labral repair, labral reconstruction was associated with a higher risk of conversion to total hip arthroplasty (THA) (20% versus 7%; adjusted odds ratio, 3.2; 95% confidence interval [CI], 1.2 to 8.8; p = 0.024). Inverse propensity score-weighted multiple regression estimated a significant negative effect of labral reconstruction, relative to labral repair, on the postoperative values for the HOS-ADL (ATT, -3.3; 95% CI, -5.8 to -0.7; p = 0.012) and WOMAC (ATT, 2.6; 95% CI, 0.1 to 5.2; p = 0.044). Compared with primary labral reconstruction, primary labral repair resulted in better postoperative HOS-ADL and WOMAC values and decreased conversion to THA. These findings were demonstrated in both the unadjusted group comparisons and multivariable modeling. These data support the use of labral repair in the primary setting of labral tears and the reservation of labral reconstruction for more advanced labral pathology or for revision cases.

Percutaneous coronary interventions for aneurysmatic right coronary artery in acute coronary syndrome: RIGHTMARE registry outcomes

BackgroundThe optimal strategy during percutaneous coronary intervention (PCI) of aneurysmatic right coronary artery (ARCA) remains uncertain and has never been tested in the acute setting. ObjectivesTo compare the in-hospital and long-term outcomes of immediate and staged PCI strategies for ARCA as culprit lesions during acute coronary syndrome (ACS). MethodsAmong 102.376 PCIs performed in 18 European centers, a total of 85 patients presenting with acute coronary syndrome undergoing ARCA PCI were finally included in the analysis. PCI strategy (stenting performed during the immediate vs staged procedure) and pharmacological approach adopted were collected. The primary outcome was procedural success (technical success without in-hospital MACE). ResultsThe primary outcome occurred in 48.2 % of cases, with no significant differences observed between the immediate and staged PCI groups (50.9 % vs 43.3 %, p = 0.504). Patients in the staged-PCI group had a significantly higher rate of intravenous anticoagulant use (83.3 % vs 48.1 %, p = 0.002), BARC type 3 and 5 bleedings (12.9 % vs 1.9 %, p = 0.037), and longer in-hospital stay (7.40 ± 5.11 vs 9.5 ± 5.25 days, p = 0.049). After multivariate analysis, no independent predictors for procedural success were found in either group. Target lesion failure occurred in 24.1 % of cases without differences between groups at a median follow-up of three years. ConclusionsAmong patients undergoing ARCA PCI in the setting of ACS, immediate or staged PCI were associated with similar in-hospital and long-term outcomes. However, staged PCI was associated with a higher risk of major bleeding events and longer length of stay compared to immediate PCI strategy.

A Multicenter Study of Unplanned Hospital Readmissions after Transsphenoidal Surgery for Cushing's Disease

Abstract Objectives Patients undergoing surgery for Cushing's disease may be more likely to be readmitted to the hospital than other patients with pituitary disorders. We investigated rates, causes, and predictors of unplanned readmission following transsphenoidal surgery for Cushing's disease to identify areas for clinical, financial, and administrative improvements. Design Retrospective cohort study. Setting Academic pituitary centers in the United States participating in a multicenter surgical outcome registry. Participants Five hundred and nineteen patients underwent transsphenoidal surgery for treatment of Cushing's disease by 26 surgeons at nine participating institutions from 2003 to 2023. Main Outcome Measures Unplanned 90-day readmission rates and causes of readmission. Results Unplanned readmissions occurred in 57/519 patients (11.0%), with hyponatremia in 12/57 (21%), cerebrospinal fluid leak evaluation in 8/57 (14%), epistaxis in 6/57 (10%), deep vein thrombosis in 4/57 (7%), syncope in 3/57 (5%), and headache in 3/57 (5%). Factors including no tumor on initial magnetic resonance imaging, return to the operating room during the index admission, lack of early remission, and inpatient complications were associated with a greater probability of readmission on univariate analysis. However, none remained predictive on multivariate analysis. Conclusion Our results show that readmission rates after transsphenoidal surgery for Cushing's disease are comparable to previously reported rates for all pituitary-related disorders, with the most common reason being hyponatremia. High-impact clinical protocols focused on preventing delayed hyponatremia may reduce the risk of readmission. Failure to identify significant predictors of readmission, even in this large clinical dataset, underscores the challenge of identifying high-risk clinical cohorts.

Rationale and Design of the Australasian Registry of Screening ECGs in National Athletes Project.

Cardiac screening of elite athletes is widely recommended by Australasian sporting federations, but data are not structured to be shared. Data are lacking from underrepresented groups to inform ECG interpretation guidelines. The ARENA (Australasian Registry of Screening ECGs in National Athletes) project is a retrospective and prospective, multicenter, longitudinal, observational registry of athlete cardiac screening results and outcomes. The aim is to create a repository to improve our understanding of the diagnoses and outcomes of screening. Participating sports that conduct cardiac screening of athletes will contribute data. This includes an initial collection (retrospective data, waiver of consent) and future prospective data (opt-out consent). Data include sex, age, sport/event, screening date, ECG findings, cardiac test results, follow-up details, sport participation status, cardiac diagnoses, and major cardiovascular outcomes defined as sudden cardiac arrest/death, cardiac syncope or implanted cardioverter defibrillator shock, cardiac hospitalization, and arrhythmias requiring intervention. Comparisons will be made between diagnoses, outcomes, and ECG features and analyzed by sport and sex. The ARENA project was developed in collaboration with sporting bodies, team physicians, and players association representatives and endorsed by the Australasian College of Sport & Exercise Physicians and Sports Medicine Australia. The ARENA project will provide a long-term international data repository to improve our understanding of ECG interpretation, cardiac screening and diagnoses, and the prevalence of cardiovascular outcomes in screened athletes. A unique aim is to address evidence gaps in underrepresented athlete groups, specifically female athletes and Indigenous populations. Results will inform screening policies and guidelines.

A Population-Based Study on Women Who Used Alcohol during Pregnancy and Their Neonates in Ontario, Canada.

Data from birth registries can be studied to assess the prevalence of prenatal alcohol use and associated maternal and neonatal outcomes. Linked maternal and neonatal data (2015-2018) for alcohol-exposed pregnancies were obtained from the Better Outcomes Registry and Network (BORN) Ontario. Descriptive statistics were generated for maternal demographics, prenatal substance use, mental health/substance use history, and neonatal outcomes. Logistic regression models were performed to assess the odds of prenatal heavy (binge or weekly) alcohol and other substance use based on mental health/substance use history and other maternal demographics, and the impacts of heavy alcohol use and other prenatal substance exposures on neonatal outcomes. A total of 10,172 (2.4%) women reported alcohol use during pregnancy. One-third had pre-existing or current mental health and/or substance use problems, which was associated with significantly higher odds of heavy alcohol use during pregnancy. Prenatal exposure to heavy alcohol use was associated with increased odds of neonatal abstinence syndrome (2.5 times); respiratory distress syndrome (2.3 times); neonatal intensive care unit (NICU) admission (58%); and hyperbilirubinemia (57%). Prenatal exposure to one or more substances in addition to alcohol was associated with significantly higher odds of fetal/maternal/placental pregnancy complications; preterm birth; NICU admission; low APGAR scores; one or more confirmed congenital anomalies at birth; respiratory distress syndrome; and intrauterine growth restriction. It is crucial to routinely screen childbearing-age and pregnant women for alcohol and other substance use as well as mental health problems in order to prevent adverse maternal and neonatal outcomes.

Impact of postoperative necrotizing enterocolitis after neonatal cardiac surgery on neurodevelopmental outcome at 1 year of age.

We analyzed the impact of postoperative necrotizing enterocolitis (NEC) after cardiac surgery in neonatal age on neurodevelopmental (ND) outcome at 1 year of age. Using data from the Swiss Neurodevelopmental Outcome Registry for Children with Congenital Heart Disease (ORCHID), we analyzed perioperative variables including postoperative NEC (Bell's stage ≥2) and 1-year ND outcome (Bayley III). The included patients (n = 101) had congenital heart disease (CHD), categorized as follows: 77 underwent biventricular repair for CHD with two functional chambers, 22 underwent staged palliation until the Fontan procedure for CHD with single ventricle physiology (n = 22), or 4 underwent single ventricle palliation or biventricular repair for borderline CHD (n = 4). Neonatal cardiopulmonary bypass (CBP) surgery was performed at a median age (IQR) of 8 (6) days. NEC occurred in 16 patients. Intensive care unit (ICU) length of stay (LOS) and the total duration of the hospitalization were longer in children with NEC than those in others (14 with vs. 8 days without NEC, p < 0.05; 49 with vs. 32 days without NEC, p < 0.05). The Bayley III scores of the analyzed patients determined at an age of 11.5 ± 1.5 months showed cognitive (CCS) (102.2 ± 15.0) and language scores (LCS) (93.8 ± 13.1) in the normal range and motor composite scores (MCS) (88.7 ± 15.9) in the low-normal range. After adjusting for socioeconomic status and CHD type, patients with NEC had lower CCS scores [β = -11.2 (SE 5.6), p = 0.049]. Using a cumulative risk score including NEC, we found a higher risk score to be associated with both lower CCS [β = -2.8 (SE 1.3), p = 0.030] and lower MCS [β = -3.20 (SE 1.3), p = 0.016]. Postoperative NEC is associated with longer ICU and hospital LOS and contributes together with other complications to impaired ND outcome at 1 year of age. In the future, national and international patient registries may provide the opportunity to analyze large cohorts and better identify the impact of modifiable perioperative risk factors on ND outcome.

The Children's National Hospital Outcomes Registry: a plea for a benchmarking tool that provides longitudinal outcomes for patients and families.

Surgical advancements in paediatric cardiovascular surgery have led to improved survival rates for those patients with the most complex CHDs leading to greater numbers of patients who are living well into adulthood. Despite this new era of long-term survival, our current reporting systems continue to focus largely on using short-term postoperative outcomes as the criteria to both rate and rank hospitals. Using such limited criteria to rate and rank hospitals may mislead the intended audiences: patients and families. The goal of this article is to describe the creation of a local benchmarking report which aims to retrospectively review long-term outcomes from our single centre. This report is updated annually and published on our cardiac surgery webpage in an effort to be as transparent as possible for our patient and family communities.

Blood Cancer Network Ireland (BCNI) and National Cancer Registry Ireland (NCRI) collaboration: challenges and utility of an Enhanced Blood Cancer Outcomes Registry (EBCOR) pilot.

The Blood Cancer Network Ireland and National Cancer Registry Ireland worked to create an Enhanced Blood Cancer Outcomes Registry (EBCOR). Enhanced data in acute myeloid leukaemia (AML) included an extensive data dictionary, bespoke software and longitudinal follow-up. To demonstrate the utility of the database, we applied the data to examine a clinically relevant question: Charlson comorbidity index (CCI) usefulness in predicting AML patients' survival. A software designer and consultant haematologists in Cork University Hospital worked together to standardise a data dictionary, train registrars and populate a database. One hundred and forty-one AML patients underwent enhanced data registration. Comorbidities identified by chart review were used to examine the capability of the CCI and age at diagnosis to predict mortality using Kaplan-Meier curves, Cox regression and receiver operating characteristic curves. In regression analysis, a dose-response relationship was observed; patients in the highest CCI tertile displayed a greater risk (HR = 4.90; 95% CI 2.79-8.63) of mortality compared to subjects in tertile 2 (HR = 2.74; 95% CI 1.64-4.57) and tertile 1 (reference). This relationship was attenuated in an analysis which adjusted for age at diagnosis. The area under the curve (AUC) for the CCI was 0.76 (95% CI 0.68-0.84) while the AUC for age at diagnosis was 0.84 (95% CI 0.78-0.90). Results suggest that the CCI provides no additional prognostic information beyond that obtained from age alone at AML diagnosis and that an EBCOR can provide a rich database for cancer outcomes research, including predictive models and resource allocation.

Consensus recommendations for acute trauma care & outcomes in LMICs from the transdisciplinary research, advocacy & implementation network for trauma in India.

Background & objectives Injuries profoundly impact global health, with substantial deaths and disabilities, especially in low- and middle-income countries (LMICs). This paper presents strategic consensus from the Transdisciplinary Research, Advocacy, and Implementation Network for Trauma in India (TRAIN Trauma India) symposium, advocating for enhanced, system-level trauma care to address this challenge. Methods Five working groups conducted separate literature reviews on pre-hospital trauma care, in-hospital trauma resuscitation and training, trauma systems, trauma registries, and India's Towards Improving Trauma Care Outcomes (TITCO) registry. Using a Delphi approach, the TRAIN Trauma India Symposium generated consensus statements and recommendations for interventions to streamline trauma care and reduce preventable trauma mortality in India and LMICs. Experts prioritized interventions based on cost and difficulty. Results An expert panel agreed on four pre-hospital consensus statements, eight hospital resuscitation consensus statements, six system-level consensus statements, and six trauma registry consensus statements. The expert panel recommended six pre-hospital interventions, four hospital resuscitation interventions, nine system-level interventions, and seven trauma registry interventions applicable to the Indian context. Of these, 14 interventions were ranked as low cost/low difficulty, five high cost/low difficulty, five low cost/high difficulty, and three high cost/high difficulty. Interpretation & conclusions This consensus underscores the urgent need for integrated and efficient trauma systems to reduce preventable mortality, emphasizing the importance of comprehensive care that includes community engagement and robust pre-hospital and acute hospital trauma care pathways. It highlights the critical role of inclusive, system-wide approaches, from enhancing pre-hospital care and in-hospital resuscitation to implementing effective trauma registries to improve outcomes and streamline care across contexts.

Treat-and-Extend Versus Pro re nata Regimens of Ranibizumab and Aflibercept in Neovascular Age-Related Macular Degeneration: A Comparative Study from Routine Clinical Practice.

Anti-vascular endothelial growth factor (VEGF) is generally given using pro re nata or "treat-and-extend" (T&E) regimens for neovascular age-related macular degeneration (nAMD). Randomized clinical trials have reported that T&E is superior to Pro re nata (PRN), but results from clinical trials may not always be replicated in clinical practice. Real-world data comparing T&E and PRN regimens for nAMD are limited. The objective of this work was to report 24-month outcomes of PRN versus T&E regimens for ranibizumab and aflibercept to treat nAMD in routine clinical practice. We conducted a retrospective analysis of data from a prospectively designed observational outcomes registry, the Fight Retinal Blindness! Project (FRB). Treatment-naïve eyes starting nAMD treatment with at least three injections using a T&E or PRN regimen were tracked by using the FRB. The primary outcome was the mean change in visual acuity (VA) measured by the number of letters read on a logarithm of the minimum angle of resolution chart at 2years versus baseline. The secondary outcome was the number of injections at 2years. From January 1, 2015 to January 31, 2019, 3313 eyes from 2948 patients with nAMD were included: 1243 eyes from 1065 patients were classified as PRN and 2070 eyes from 1935 patients started a T&E regimen. At 24months, patients on the T&E regimen experienced significantly greater mean (95% confidence interval) improvement in VA than those on PRN (+ 4.2 [3.1, 5.2] vs. + 1.3 [0.1, 2.6] letters; p < 0.001), with more injections (14.9 standard deviation(SD) 4.3) vs. 9.8(SD 4.3); p < 0.001). Eyes treated with a T&E regimen had better VA outcomes from VEGF inhibitors than eyes treated PRN. This large real-world data assessment supports previous data from randomized clinical trials that the T&E regimen delivers better outcomes than PRN.

Anesthetic Choice for Percutaneous Transcatheter Closure of the Left Atrial Appendage: A National Anesthesia Clinical Outcomes Registry Analysis.

Left atrial appendage closure (LAAC) was developed as a novel stroke prevention alternative for patients with atrial fibrillation, particularly for those not suitable for long-term oral anticoagulant therapy. Traditionally, general anesthesia (GA) has been more commonly used primarily due to the necessity of transesophageal echocardiography. Compare trends of monitored anesthesia care (MAC) versus GA for percutaneous transcatheter LAAC with endocardial implant and assess for independent variables associated with primary anesthetic choice. Multi-institutional data collected from across the United States using the National Anesthesia Clinical Outcomes Registry. Retrospective data analysis from 2017-2021. Independent-sample t tests or Mann-Whitney U tests were used for continuous variables and Chi-square tests or Fisher's exact test for categorical variables. Multivariate logistic regression was used to assess patient and hospital characteristics. A total of 19,395 patients underwent the procedure, and 352 patients (1.8%) received MAC. MAC usage trended upward from 2017-2021 (P < 0.0001). MAC patients were more likely to have an American Society of Anesthesiologists (ASA) physical status of≥ 4 (33.6% vs 22.89%) and to have been treated at centers in the South (67.7% vs 44.2%), in rural locations (71% vs 39.5%), and with lower median annual percutaneous transcatheter LAAC volume (102 vs 153 procedures) (all P < 0.0001). In multivariate analysis, patients treated in the West had 85% lower odds of receiving MAC compared to those in the Northeast (AOR: 0.15; 95% CI 0.03-0.80, P = 0.0261). While GA is the most common anesthetic technique for percutaneous transcatheter closure of the left atrial appendage, a small, statistically significant increase in MAC occurred from 2017-2021. Anesthetic management for LAAC varies with geographic location.

Effect of COVID-19 Pandemic Lockdown on Emergency Medical Service Utilisation, and Percutaneous Coronary Intervention Volume—An Australian Perspective

Acute coronary syndrome (ACS) admissions and percutaneous coronary intervention (PCI) volume declined during periods of COVID-19 lockdown internationally in 2020. The effect of lockdown on emergency medical service (EMS) utilisation, and PCI volume during the initial phase of the pandemic in Australia has not been well described. We analysed data from the Victorian Cardiac Outcomes Registry (VCOR), a state-wide PCI registry, linked with the Ambulance Victoria EMS registry. PCI volume, 30-day major adverse cardiovascular and cerebrovascular events (MACCE; composite of mortality, myocardial infarction, stent thrombosis, unplanned revascularisation, and stroke), and EMS utilisation were compared over four time periods: lockdown (26 Mar 2020-12 May 2020); pre-lockdown (26 Feb 2020-25 Mar 2020); post-lockdown (13 May 2020-10 Jul 2020); and the year prior (26 Mar 2019-12 May 2019). Interrupted time series analysis was performed to assess PCI trends within and between consecutive periods. The EMS utilisation for ACS during lockdown was higher compared with other periods: lockdown 39.4% vs pre-lockdown 29.7%; vs post-lockdown 33.6%; vs year prior 27.1%; all p<0.01. Median daily PCI cases were similar: 31 (IQR 10, 38) during lockdown; 39 (15, 49) pre-lockdown; 39.5 (11, 44) post-lockdown; and, 42 (10, 49) the year prior; all p>0.05. Median door-to-procedure time for ACS indication during lockdown was shorter at 3 hours (1.2, 20.6) vs pre-lockdown 3.9 (1.7, 21); vs post-lockdown 3.5 (1.5, 21.26); and, the year prior 3.5 (1.5, 23.7); all p<0.05. Lockdown period was associated with lower odds for 30-day MACCE compared to pre-lockdown (odds ratio [OR] 0.55 [0.33-0.93]; p=0.026); post-lockdown (OR 0.66; [0.40-1.06]; p=0.087); and the year prior (OR 0.55 [0.33-0.93]; p=0.026). Contrary to international trends, EMS utilisation for ACS increased during lockdown but PCI volumes remained similar throughout the initial stages of the pandemic in Victoria, with no observed adverse effect on 30-day MACCE during lockdown. These data suggest that the public health response in Victoria was not associated with poorer quality cardiovascular care in patients receiving PCI.

Poster 182: Pain and Quality of Life Scores Following Hip Arthroscopy for Femoroacetabular Impingement are More Related to Mental Health Than Hip Pathology

Objectives: Symptom severity in patients with femoroacetabular impingement (FAI) has been demonstrated to have a stronger association with mental health status than pathology. However, there is limited data on the relationship between mental health status and postoperative outcomes in FAI patients. This study aims to evaluate the relationship of mental health status and structural hip pathology to pain and quality of life. Methods: This was a retrospective review of patients from a single surgeon’s hip outcomes registry. Mental health status was evaluated using the Patient-Reported Outcomes Measurement Information System (PROMIS)-Anxiety and PROMIS-Depression scores. Pain was evaluated with Single Assessment Numerical Evaluation Score for Activities of Daily Living (SANE ADL) while quality of life (QOL) was evaluated with the International Hip Outcome Tool (iHOT-12). Repeated measures mixed modeling was used to evaluate the association between hip pathology (size of labral tear, grade of chondral damage, preoperative alpha angle), pain, QOL, anxiety, and depression pre- and postoperatively. Results: A total of 337 patients were included in this study. The degree of preoperative alpha angle, intra-operative cartilage damage and size of labral tear did not influence postoperative improvements in pain or QOL (p&gt;0.05). However, higher levels of anxiety and depression were significantly associated with lower SANE-ADL scores (anxiety estimate: -0.608, SE (0.079), p&lt;0.0001), (depression estimate: -0.677, SE (0.086), p&lt;0.0001), and lower iHOT-12 scores (anxiety estimate: -0.709, SE (0.069), p&lt;0.0001), (depression estimate: -0.706, SE (0.077), p&lt;0.0001). These associations were seen both preoperatively and up to 2 years postoperatively. Furthermore, anxiety and depression do not appear to moderate the relationship between hip pathology and patient outcomes. Conclusions: All patients had similar improvements in pain scores and QOL following hip arthroscopy for FAI suggesting this surgery is beneficial for varying degrees of hip pathology. Additionally, preoperative anxiety and depression are associated with greater pain and decreased QOL both pre- and postoperatively regardless of the degree of hip pathology. This may suggest a need for pre- and postoperative psychological interventions in patients with anxiety and depression, and clinicians should prioritize mental health treatment at or above the level of the hip pathology itself.

Comparative cost-effectiveness of termination of resuscitation rules for patients transported in cardiac arrest

AimTo compare the cost-effectiveness of termination-of-resuscitation (TOR) rules for patients transported in cardiac arrest. MethodsThe economic analyses evaluated cost-effectiveness of alternative TOR rules for OHCA from a National Health Service (NHS) and personal social services (PSS) perspective over a lifetime horizon. A systematic review was used to identify the different TOR rules included in the analyses. Data from the OHCAO outcomes registry, trial data and published literature were used to compare outcomes for the different rules identified. The economic analyses estimated discounted NHS and PSS costs and quality-adjusted life-years (QALYs) for each TOR rule, based on which incremental cost-effectiveness ratios (ICERs) were calculated. ResultsThe systematic review identified 33 TOR rules and the economic analyses assessed the performance of 29 of these TOR rules plus current practice. The most cost-effective strategies were the European Resuscitation Council (ERC) termination of resuscitation rule (ICER of £8,111), the Korean Cardiac Arrest Research Consortium 2 (KOC 2) termination of resuscitation rule (ICER of £17,548), and the universal Basic Life Support (BLS) termination of resuscitation rule (ICER of £19,498,216). The KOC 2 TOR rule was cost-effective at the established cost-effectiveness threshold of £20,000–£30,000 per QALY. ConclusionThe KOC 2 rule is the most cost-effective at established cost-effectiveness thresholds used to inform health care decision-making in the UK. Further research on economic implications of TOR rules is warranted to support constructive discussion on implementing TOR rules.

Temporal Trends in Gestational Diabetes Mellitus and Associated Risk Factors in Ontario, Canada, 2012–2020: A Population-Based Cohort Study

ObjectivesThe prevalence of gestational diabetes mellitus (GDM) has been increasing globally over recent decades; however, underlying reasons for the increase remain unclear. We analyzed trends in GDM rates and evaluated risk factors associated with the observed trends in Ontario, Canada. MethodsWe conducted a retrospective population-based cohort study using the Better Outcomes Registry and Network Ontario, linked with the Canadian Institute for Health Information Discharge Abstract Database. All pregnant individuals who had a singleton hospital delivery from 1 April 2012 to 31 March 2020 were included. We calculated rates and 95% CIs for GDM by year of delivery and contrasted fiscal year 2019/20 with 2012/13. Temporal trends in GDM were quantified using crude and adjusted risk ratios by modified Poisson regression. We further quantified the temporal increase attributable to changes in maternal characteristics by decomposition analysis. ResultsAmong 1 044 258 pregnant individuals, 82 896 (7.9%) were diagnosed with GDM over the 8 years. GDM rate rose from 6.1 to 10.4 per 100 deliveries between fiscal years 2012/13 and 2019/20. The risk of GDM in 2019/20 was 1.53 times (95% CI 1.50-1.56) higher compared with 2012/13. 27% of the increase in GDM was due to changes in maternal age, 8 BMI, and Asian ethnicity. ConclusionsThe GDM rate has been consistently increasing in Ontario, Canada. The contribution of increasing maternal age, pre-pregnancy obesity, and Asian ethnicity to the recent increase in GDM is notable. Further investigation is required to better understand the contributors to increasing GDM.

Ten-Year Review of the Postpartum Maternal Health Clinic at the Kingston Health Sciences Centre

ObjectivesThe postpartum Maternal Health Clinic (MHC) sees patients who have experienced pregnancy complications identified as pregnancy-related cardiovascular disease (CVD) risk indicators (hypertensive disorders of pregnancy, gestational diabetes, placental abruption, idiopathic preterm delivery, and intrauterine growth restriction) at 6 months postpartum for CVD risk screening. This project aimed to summarise the past 10 years of the MHC and identify trends in patient characteristics, patient CVD risk assessments, and clinic attendance over time. MethodsPatients included in this study have experienced 1 or more pregnancy-related CVD risk indicator(s) and have delivered between April 2011 and April 2021. MHC patient data and the Better Outcomes Registry Network database were utilised to compare eligible and participating patient data during clinically significant time periods. ResultsThe clinic has seen 1030 patients in the last 10 years and their characteristics have remained largely consistent. However, there has been an increase in the proportion of patients seen because of a hypertensive disorder and an increase in the proportion of patients with obesity, abnormal total cholesterol, and elevated fasting glucose. Additionally, CVD risk scores and the prevalence of metabolic syndrome have remained consistent over the years. Regarding the clinic’s outreach, patient eligibility for the MHC has been increasing while attendance has been decreasing over time. ConclusionsOverall, there remains a need to screen these patients for CVD risk and counsel them on risk reduction. There is also an opportunity to increase patient recruitment to improve attendance and to address the increased need for CVD risk screening and counselling in the community.
