RESUMO
OBJECTIVES: To evaluate the carbon footprint of the perioperative transurethral resection of bladder tumour (TURBT) pathway from decision to treat to postoperative discharge, and model potential greenhouse gas (GHG) emissions reduction strategies. MATERIALS AND METHODS: This process-based attributional cradle-to-grave life-cycle assessment (LCA) of GHG emissions modelled the perioperative TURBT pathway at a hospital in Southwest England. We included travel, energy and water use, all reusable and consumable items, and laundry and equipment sterilisation. Resource use for 30 patients undergoing surgery was recorded to understand average GHG emissions and the inter-case variability. Sensitivity analysis was performed for manufacturing location, pharmaceutical manufacturing carbon-intensity, and theatre list utilisation. RESULTS: The median (interquartile range) perioperative TURBT carbon footprint was 131.8 (119.8-153.6) kg of carbon dioxide equivalent. Major pathway categories contributing to GHG emissions were surgical equipment (22.2%), travel (18.6%), gas and electricity (13.3%), and anaesthesia/drugs and associated adjuncts (27.0%), primarily due to consumable items and processes. Readily modifiable GHG emissions hotspots included patient travel for preoperative assessment, glove use, catheter use, irrigation delivery and extraction, and mitomycin C disposal. GHG emissions were higher for those admitted as inpatients after surgery. CONCLUSIONS: This cradle-to-grave LCA found multiple modifiable GHG emissions hotspots. Key mitigation themes include minimising avoidable patient travel, rationalising equipment use, optimally filling operating theatre lists, and safely avoiding postoperative catheterisation and hospital admission where possible. A crucial next step is to design and deliver an implementation strategy for the environmentally sustainable changes demonstrated herein.
RESUMO
HIV-associated neurocognitive disorders (HAND) are highly prevalent in those ageing with HIV. High-income country data suggest that vascular risk factors (VRFs) may be stronger predictors of HAND than HIV-disease severity, but data from sub-Saharan Africa are lacking. We evaluated relationships of VRFs, vascular end-organ damage and HAND in individuals aged ≥ 50 in Tanzania. c-ART-treated individuals were assessed for HAND using consensus criteria. The prevalence of VRFs and end organ damage markers were measured. The independent associations of VRFs, end organ damage and HAND were examined using multivariable logistic regression. Data were available for 153 individuals (median age 56, 67.3% female). HAND was highly prevalent (66.7%, 25.5% symptomatic) despite well-managed HIV (70.5% virally suppressed). Vascular risk factors included hypertension (34%), obesity (10.5%), hypercholesterolemia (33.3%), diabetes (5.3%) and current smoking (4.6%). End organ damage prevalence ranged from 1.3% (prior myocardial infarction) to 12.5% (left ventricular hypertrophy). Measured VRFs and end organ damage were not independently associated with HAND. The only significant association was lower diastolic BP (p 0.030, OR 0.969 (0.943-0.997). Our results suggest that vascular risk factors are not major drivers of HAND in this setting. Further studies should explore alternative aetiologies such as chronic inflammation.

INTRODUCTION: Abdominal wall reconstruction (AWR) is an emerging specialty, involving complex multi-stage operations in patients with high medical and surgical risk. At our hospital, we have developed a growing interest in AWR, with a commitment to improving outcomes through a regular complex hernia MDT. An MDT approach to these patients is increasingly recognized as the path forward in management to optimize patients and improve outcomes. METHODS: We conducted a literature review and combined this with our experiential knowledge of managing these cases to create a pathway for the management of our abdominal wall patients. This was done under the auspices of GIRFT (Getting It Right First Time) as a quality improvement project at our hospital. RESULTS: We describe, in detail, our current AWR pathway, including the checklists and information documents we use with a stepwise evidence and experience-based approach to identifying the multiple factors associated with good outcomes. We explore the current literature and discuss our best practice pathway. CONCLUSION: In this emerging specialty, there is limited guidance on the management of these patients. Our pathway, the "Complex Hernia Bundle," currently provides guidance for our abdominal wall team and may well be one that could be adopted/adapted by other centers where challenging hernia cases are undertaken.

INTRODUCTION: Two of the main reasons recent guidelines do not recommend routine population-wide screening programs for asymptomatic carotid artery stenosis (AsxCS) is that screening could lead to an increase of carotid revascularization procedures and that such mass screening programs may not be cost-effective. Nevertheless, selective screening for AsxCS could have several benefits. This article presents the rationale for such a program. AREAS COVERED: The benefits of selective screening for AsxCS include early recognition of AsxCS allowing timely initiation of preventive measures to reduce future myocardial infarction (MI), stroke, cardiac death and cardiovascular (CV) event rates. EXPERT OPINION: Mass screening programs for AsxCS are neither clinically effective nor cost-effective. Nevertheless, targeted screening of populations at high risk for AsxCS provides an opportunity to identify these individuals earlier rather than later and to initiate a number of lifestyle measures, risk factor modifications, and intensive medical therapy in order to prevent future strokes and CV events. For patients at 'higher risk of stroke' on best medical treatment, a prophylactic carotid intervention may be considered.

OBJECTIVES: The efficacy of hybrid robotic-assisted coronary artery bypass grafting (CABG) and transcatheter aortic valve replacement (TAVR) for coronary and aortic valve disease is poorly reported. Herein, we report our experience with this hybrid approach. METHODS: Between January 2018 and June 2022, 10 (7 male, 3 female) patients with a mean age of 81 years underwent the hybrid procedure. Coronary revascularization was performed prior to TAVR with robotic-assisted left internal mammary artery-to-left anterior descending (LAD) bypass grafting for left main or proximal LAD lesions with or without multivessel disease with or without hybrid percutaneous coronary intervention (PCI). RESULTS: Five patients had left main disease, and 5 had proximal LAD disease with or without multivessel disease. All patients tolerated the robotic-assisted CABG procedure well; 9 patients were extubated in the operating room and all patients were ambulatory on postoperative day 1. Five patients underwent hybrid PCI for non-LAD lesions. TAVR was subsequently performed at intervals ranging from 3 days to 5 months after CABG. One patient with end-stage renal disease on hemodialysis required hospitalization for heart failure during the interval period. The 1-year mortality rate was 0%, and 3 patients died during late follow-up (24-43 months). CONCLUSIONS: This innovative, less invasive approach demonstrates the potential for early recovery in appropriately selected patients with complex coronary and aortic valve disease with promising mid-term outcomes.

PURPOSE: This study aimed to identify factors associated with poorer patient outcomes for lumbar decompression and/or discectomy (PLDD). METHODS: We extracted data from the Hospital Episodes Statistics database for the 5 years from 1st April 2014 to 31st March 2019. Patients undergoing an elective one- or two-level PLDD aged ≥ 17 years and without evidence of revision surgery during the index stay were included. The primary patient outcome measure was readmission within 90 days post-discharge. RESULTS: Data for 93,813 PLDDs across 111 hospital trusts were analysed. For the primary outcome, greater age [< 40 years vs 70-79 years odds ratio (OR) 1.28 (95% confidence interval (CI) 1.14 to 1.42), < 40 years vs ≥ 80 years OR 2.01 (95% CI 1.76-2.30)], female sex [OR 1.09 (95% CI 1.02-1.16)], surgery over two spinal levels [OR 1.16 (95% CI 1.06-1.26)] and the comorbidities chronic pulmonary disease, connective tissue disease, liver disease, diabetes, hemi/paraplegia, renal disease and cancer were all associated with emergency readmission within 90 days. Other outcomes studied had a similar pattern of associations. CONCLUSIONS: A high-throughput PLDD pathway will not be suitable for all patients. Extra care should be taken for patients aged ≥ 70 years, females, patients undergoing surgery over two spinal levels and those with specific comorbidities or generalised frailty.

Outcomes of robotic-assisted reverse hybrid coronary revascularization (HCR) remain hindered. We aimed to analyze midterm clinical outcomes of robotic-assisted reverse HCR. All consecutive 285 patients who underwent reverse robotic-assisted HCR between September 2005 and July 2021 were included. Reverse HCR comprises percutaneous coronary intervention with stent implantation in non-left anterior descending (LAD) coronary arteries was performed within 30 days before robotic-assisted left internal thoracic artery (LITA) harvesting and LITA-to-LAD manual anastomosis through a 4-cm left minithoracotomy. Dual antiplatelet therapy was not interrupted in any patient. Preoperatively, mean age was 70.2 years (±11.2). Before surgery, 168 patients received 1 stent, 112 patients 2 stents, and 5 patients 3 stents. Intraoperatively, mean operating room time was 5.9 hours (±1); no case was converted to full sternotomy, whereas 9 patients (3.1%) received intraoperative blood product transfusions. Postoperatively, a small incidence of stroke, 1 (0.3%), reoperation for bleeding, 7 (2.4%), blood product transfusions, 48 (16.8%), and hospital stay (4.8 days) was observed. At 30-day follow-up, 1 patient (0.3%) underwent percutaneous coronary intervention with stent on a surgical LITA-LAD anastomosis owing to graft failure. Mean follow-up was 4.2 years. Reported midterm outcomes included all-cause death in 31 patients (10.9%), major adverse cardiovascular and cerebrovascular events in 102 of 285 (35.9%), nonfatal stroke in 2 of 285 (0.7%), myocardial infarction in 17 of 285 (5.9%), and repeat intervention in 50 of 285 patients (17.5%). This single-center study reports effective and safe clinical outcomes at midterm follow-up of reverse HCR procedures for treating multivessel coronary artery disease.

OBJECTIVE: The optimal management of patients with asymptomatic carotid stenosis (AsxCS) is enduringly controversial. We updated our 2021 Expert Review and Position Statement, focusing on recent advances in the diagnosis and management of patients with AsxCS. METHODS: A systematic review of the literature was performed up to August 1, 2023, using PubMed/PubMed Central, EMBASE and Scopus. The following keywords were used in various combinations: "asymptomatic carotid stenosis," "carotid endarterectomy" (CEA), "carotid artery stenting" (CAS), and "transcarotid artery revascularization" (TCAR). Areas covered included (i) improvements in best medical treatment (BMT) for patients with AsxCS and declining stroke risk, (ii) technological advances in surgical/endovascular skills/techniques and outcomes, (iii) risk factors, clinical/imaging characteristics and risk prediction models for the identification of high-risk AsxCS patient subgroups, and (iv) the association between cognitive dysfunction and AsxCS. RESULTS: BMT is essential for all patients with AsxCS, regardless of whether they will eventually be offered CEA, CAS, or TCAR. Specific patient subgroups at high risk for stroke despite BMT should be considered for a carotid revascularization procedure. These patients include those with severe (≥80%) AsxCS, transcranial Doppler-detected microemboli, plaque echolucency on Duplex ultrasound examination, silent infarcts on brain computed tomography or magnetic resonance angiography scans, decreased cerebrovascular reserve, increased size of juxtaluminal hypoechoic area, AsxCS progression, carotid plaque ulceration, and intraplaque hemorrhage. Treatment of patients with AsxCS should be individualized, taking into consideration individual patient preferences and needs, clinical and imaging characteristics, and cultural, ethnic, and social factors. Solid evidence supporting or refuting an association between AsxCS and cognitive dysfunction is lacking. CONCLUSIONS: The optimal management of patients with AsxCS should include BMT for all individuals and a prophylactic carotid revascularization procedure (CEA, CAS, or TCAR) for some asymptomatic patient subgroups, additionally taking into consideration individual patient needs and preference, clinical and imaging characteristics, social and cultural factors, and the available stroke risk prediction models. Future studies should investigate the association between AsxCS with cognitive function and the role of carotid revascularization procedures in the progression or reversal of cognitive dysfunction.

OBJECTIVES: To describe the contemporary evolution of day-case bladder outflow obstruction (BOO) surgery in England and to profile day-case BOO surgery practices across England in terms of the types of operation performed and their safety profiles. MATERIALS AND METHODS: This was a retrospective observational analysis of Hospital Episode Statistics and UK Office for National Statistics data. All 111 043 recorded operations across 117 hospital trusts over 66 months, from 1 January 2017 to 30 June 2022, were obtained. Operations were identified as one of: transurethral resection of prostate (TURP); laser ablation or enucleation; vapour therapy; prostatic urethral lift (PUL); or bladder neck incision. Monthly day-case rate trends were plotted across the study period. Descriptive data, day-case rates and 30-day hospital readmissions were analysed for each operation type. Multilevel regression modelling with mixed effects was performed to determine whether day-case surgery was associated with higher 30-day hospital readmissions. RESULTS: Day-case patients were younger, with fewer comorbidities. Time series analysis showed a linear day-case rate increase from 8.3% (January 2017) to 21.0% (June 2022). Day-case rates improved for 92/117 trusts in 2021/2022 compared with 2017. Three of the six trusts with the highest day-case rates performed predominantly day-case TURP, and the other three laser surgery. Nationally, PUL and vapour surgery had the highest day-case rates (80.9% and 38.1%). Most inpatient operations were TURP. Multilevel regression modelling found reduced odds of 30-day readmission after day-case BOO surgery (all operations pooled), no difference for day-case vs inpatient TURP, and reduced odds following day-case LASER operations. CONCLUSIONS: The day-case rates for BOO surgery have linearly increased. Minimally invasive surgical technologies are commonly performed as day cases, whereas high day-case rates for TURP and for laser ablation operations are seen in a minority of hospitals. Day-case pathways to treat BOO can be safely developed irrespective of operative modality.

BACKGROUND: Patients who are not candidates for traditional coronary artery bypass grafting (CABG) and amenable only for percutaneous coronary intervention (PCI) with stents can receive the "gold standard" left internal thoracic artery (LITA) to left anterior descending artery (LAD) anastomosis through robotic-assisted CABG and PCI to non-LAD coronary targets. AIMS: We aimed to analyse clinical outcomes of robotic-assisted CABG. METHODS: A total of 2,280 consecutive patients who had undergone robotic-assisted CABG between May 2005 and June 2021 were included in our study. Robotic-assisted LITA harvest was followed by LITA-LAD manual anastomosis through a 4 cm left thoracotomy. Hybrid coronary intervention (HCR) consists of stent implantation in a non-LAD coronary artery performed within 7 days after robotic-assisted LITA-LAD. We performed a propensity-adjusted analysis comparison after dividing all robotic-assisted CABG patients into three time periods: 2005-2010, 615 patients; 2011-2016, 904 patients; and 2017-2021, 761 patients. RESULTS: The mean age increased from 64.5 years in the first time period to 65.8 years in the second time period to 68.1 years in the third (p<0.0001). Operative time was progressively reduced in the three periods (6.4; 6.2; 5.5 hours; p<0.001). The incidence of conversion to sternotomy remained similar for each period (1.8%; 1.7%; 1.5%; p=0.53). Thirty-day mortality in the three periods included 9 (1.4%), 9 (1.0%), and 7 (0.9%) patients, respectively (p=0.91), while 8 (0.3%) patients had PCI with stents in the entire group. The mean follow-up for the entire population was 4.2 years. At follow-up, the rates of all-cause death, major adverse cardiac and cerebrovascular events, non-fatal stroke, and repeat revascularisation with stents were significantly decreased from the first to the last period (pË0.0001). CONCLUSIONS: Robotic-assisted CABG and HCR provide good long-term outcomes in patients who are not candidates for conventional CABG.

OBJECTIVE: Despite the publication of various national/international guidelines, several questions concerning the management of patients with asymptomatic (AsxCS) and symptomatic (SxCS) carotid stenosis remain unanswered. The aim of this international, multi-specialty, expert-based Delphi Consensus document was to address these issues to help clinicians make decisions when guidelines are unclear. METHODS: Fourteen controversial topics were identified. A three-round Delphi Consensus process was performed including 61 experts. The aim of Round 1 was to investigate the differing views and opinions regarding these unresolved topics. In Round 2, clarifications were asked from each participant. In Round 3, the questionnaire was resent to all participants for their final vote. Consensus was reached when ≥75% of experts agreed on a specific response. RESULTS: Most experts agreed that: (1) the current periprocedural/in-hospital stroke/death thresholds for performing a carotid intervention should be lowered from 6% to 4% in patients with SxCS and from 3% to 2% in patients with AsxCS; (2) the time threshold for a patient being considered "recently symptomatic" should be reduced from the current definition of "6 months" to 3 months or less; (3) 80% to 99% AsxCS carries a higher risk of stroke compared with 60% to 79% AsxCS; (4) factors beyond the grade of stenosis and symptoms should be added to the indications for revascularization in AsxCS patients (eg, plaque features of vulnerability and silent infarctions on brain computed tomography scans); and (5) shunting should be used selectively, rather than always or never. Consensus could not be reached on the remaining topics due to conflicting, inadequate, or controversial evidence. CONCLUSIONS: The present international, multi-specialty expert-based Delphi Consensus document attempted to provide responses to several unanswered/unresolved issues. However, consensus could not be achieved on some topics, highlighting areas requiring future research.

AIMS: We evaluated the effectiveness of an intervention to improve the care of people with diabetes undergoing surgery when implemented across multiple organisations. METHODS: This was an observational study using routinely collected data. Eight hospitals in England implemented the Improving the Peri-operative Pathway of People with Diabetes (IP3D) intervention, with pre-implementation data collected from 1st February to 31st July 2019 and post-implementation data collection within the period 1st February to 31st October 2021. Key elements were the use of a patient empowering peri-operative passport and the employment of a peri-operative diabetes specialist nurse. The primary outcome was the change in length of stay. RESULTS: In total 1837 patients at pre-implementation and 1164 patients at post-implementation undergoing elective surgery were included. Pre- and post-implementation 23.8 % and 33.4 % of patients had day-case surgery respectively. For in-patients median length of stay decreased from 3.2 days (inter-quartile range 1.5-6.1) pre-implementation to 2.5 days (inter-quartile range 1.4-5.4) post-implementation. There were also significant improvements in patient experience, hypo- and hyper-glycaemic events, wound complications and diabetes related complications. CONCLUSIONS: The IP3D intervention has the potential to increase efficiency and reduce waiting lists for elective surgery on a nationwide basis.

Background: The National Health Service (NHS) in England has set a net-zero target for carbon emissions by 2040. Increasing use of day-case surgery pathways may help in meeting this target. Objective: To investigate the estimated difference in carbon footprint between day-case and inpatient transurethral resection of bladder tumour (TURBT) surgery in England. Design setting and participants: This was a retrospective analysis of administrative data extracted from the Hospital Episode Statistics database for all TURBT procedures conducted in England from April 1, 2013 to March 31, 2022. Outcome measurements and statistical analysis: Day-case and inpatient TURBT procedures were identified and the carbon footprint for key elements of the surgical pathway was estimated using data from Greener NHS and the Sustainable Healthcare Coalition. Results and limitations: Of 209 269 TURBT procedures identified, 41 583 (20%) were classified as day-case surgery. The day-case rate increased from 13% in 2013-2014 to 31% in 2021-2022. The move from inpatient stays to day-case surgery between 2013-2014 and 2021-2022 demonstrates a trend toward a lower-carbon pathway, with an estimated saving of 2.9 million kg CO2 equivalents (equivalent to powering 2716 homes for 1 yr) in comparison to no change in practice. We calculated that potential carbon savings for the financial year 2021-2022 would be 217 599 kg CO2 equivalents (equivalent to powering 198 homes for 1 yr) if all hospitals in England not already in the upper quartile were able to achieve the current upper-quartile day-case rate. Our study is limited in that estimates are based on carbon factors for generic surgical pathways. Conclusions: Our study highlights potential NHS carbon savings that could be achieved by moving from inpatient stays to day-case surgery. Reducing variation in care across the NHS and encouraging all hospitals to adopt day-case surgeries, where clinically appropriate, would lead to further carbon savings. Patient summary: In this study we estimated the potential for carbon savings if patient undergoing bladder tumour surgery were admitted and discharged on the same day. We estimate that increasing use of day-case surgery between 2013-2014 and 2021-2022 has saved 2.9 million kg CO2 equivalents. If all hospitals were to achieve day case-rates comparable to those in the highest quarter of hospitals in England in 2021-2022, then the carbon equivalent to powering 198 homes for 1 year could have been saved.
RESUMO
Aims: Revision total knee arthroplasty (rTKA) and revision total hip arthroplasty (rTHA) are complex procedures with higher rates of re-revision, complications, and mortality compared to primary TKA and THA. We report the effects of the establishment of a revision arthroplasty network (the East Midlands Specialist Orthopaedic Network; EMSON) on outcomes of rTKA and rTHA. Methods: The revision arthroplasty network was established in January 2015 and covered five hospitals in the Nottinghamshire and Lincolnshire areas of the East Midlands of England. This comprises a collaborative weekly multidisciplinary meeting where upcoming rTKA and rTHA procedures are discussed, and a plan agreed. Using the Hospital Episode Statistics database, revision procedures carried out between April 2011 and March 2018 (allowing two-year follow-up) from the five network hospitals were compared to all other hospitals in England. Age, sex, and mean Hospital Frailty Risk scores were used as covariates. The primary outcome was re-revision surgery within one year of the index revision. Secondary outcomes were re-revision surgery within two years, any complication within one and two years, and median length of hospital stay. Results: A total of 57,621 rTHA and 33,828 rTKA procedures were performed across England, of which 1,485 (2.6%) and 1,028 (3.0%), respectively, were conducted within the network. Re-revision rates within one year for rTHA were 7.3% and 6.0%, and for rTKA were 11.6% and 7.4% pre- and postintervention, respectively, within the network. This compares to a pre-to-post change from 7.4% to 6.8% for rTHA and from 11.7% to 9.7% for rTKA for the rest of England. In comparative interrupted time-series analysis for rTKA there was a significant immediate improvement in one-year re-revision rates for the revision network compared to the rest of England (p = 0.024), but no significant change for rTHA (p = 0.504). For the secondary outcomes studied, there was a significant improvement in trend for one- and two-year complication rates for rTHA for the revision network compared to the rest of England. Conclusion: Re-revision rates for rTKA and complication rates for rTHA improved significantly at one and two years with the introduction of a revision arthroplasty network, when compared to the rest of England. Most of the outcomes studied improved to a greater extent in the network hospitals compared to the rest of England when comparing the pre- and postintervention periods.

BACKGROUND: Setting minimum annual volume thresholds for pituitary surgery in England is seen as one way of improving outcomes for patients and service efficiency. However, there are few recent studies from the UK on whether a volume-outcome effect exists, particularly in the era of endoscopic surgery. Such data are needed to allow evidence-based decision making. The aim of this study was to use administrative data to investigate volume-outcome effects for endoscopic transsphenoidal pituitary surgery in England. METHODS: Data from the Hospital Episodes Statistics database for adult endoscopic transsphenoidal pituitary surgery for benign neoplasm conducted in England from April 2013 to March 2019 (inclusive) were extracted. Annual surgeon and trust volume was defined as the number of procedures conducted in the 12 months prior to the index procedure. Volume was categorised as < 10, 10-19, 20-29, 30-39 and ≥40 procedures for surgeon volume and < 20, 20-39, 40-59, 60-79 and ≥80 procedures for trust volume. The primary outcome was repeat ETSPS during the index procedure or during a hospital admission within one-year of discharge from the index procedure. RESULTS: Data were available for 4590 endoscopic transsphenoidal pituitary procedures. After adjustment for covariates, higher surgeon volume was significantly associated with reduced risk of repeat surgery within one year (odds ratio (OR) 0.991 (95% confidence interval (CI) 0.982-1.000)), post-procedural haemorrhage (OR 0.977 (95% CI 0.967-0.987)) and length of stay greater than the median (0.716 (0.597-0.859)). A higher trust volume was associated with reduced risk of post-procedural haemorrhage (OR 0.992 (95% CI 0.985-0.999)), but with none of the other patient outcomes studied. CONCLUSIONS: A surgeon volume-outcome relationship exists for endoscopic transsphenoidal pituitary surgery in England.
RESUMO
More than half of adults with epilepsy undergoing resective epilepsy surgery achieve long-term seizure freedom and might consider withdrawing antiseizure medications. We aimed to identify predictors of seizure recurrence after starting postoperative antiseizure medication withdrawal and develop and validate predictive models. We performed an international multicentre observational cohort study in nine tertiary epilepsy referral centres. We included 850 adults who started antiseizure medication withdrawal following resective epilepsy surgery and were free of seizures other than focal non-motor aware seizures before starting antiseizure medication withdrawal. We developed a model predicting recurrent seizures, other than focal non-motor aware seizures, using Cox proportional hazards regression in a derivation cohort (n = 231). Independent predictors of seizure recurrence, other than focal non-motor aware seizures, following the start of antiseizure medication withdrawal were focal non-motor aware seizures after surgery and before withdrawal [adjusted hazard ratio (aHR) 5.5, 95% confidence interval (CI) 2.7-11.1], history of focal to bilateral tonic-clonic seizures before surgery (aHR 1.6, 95% CI 0.9-2.8), time from surgery to the start of antiseizure medication withdrawal (aHR 0.9, 95% CI 0.8-0.9) and number of antiseizure medications at time of surgery (aHR 1.2, 95% CI 0.9-1.6). Model discrimination showed a concordance statistic of 0.67 (95% CI 0.63-0.71) in the external validation cohorts (n = 500). A secondary model predicting recurrence of any seizures (including focal non-motor aware seizures) was developed and validated in a subgroup that did not have focal non-motor aware seizures before withdrawal (n = 639), showing a concordance statistic of 0.68 (95% CI 0.64-0.72). Calibration plots indicated high agreement of predicted and observed outcomes for both models. We show that simple algorithms, available as graphical nomograms and online tools (predictepilepsy.github.io), can provide probabilities of seizure outcomes after starting postoperative antiseizure medication withdrawal. These multicentre-validated models may assist clinicians when discussing antiseizure medication withdrawal after surgery with their patients.

INTRODUCTION: As elective surgical services recover from the COVID-19 pandemic a movement towards day-case surgery may reduce waiting lists. However, evidence is needed to show that day-case surgery is safe for endoscopic sinus surgery (ESS). The aim of this study was to investigate the safety of day-case ESS in England. DESIGN: Secondary analysis of administrative data. METHODS: We extracted data from the Hospital Episodes Statistics database for the 5 years from 1 April 2014 to 31 March 2019. Patients undergoing elective ESS procedures aged ≥17 years were included. Exclusion criteria included malignant neoplasm, complex systemic disease and trans-sphenoidal pituitary surgery. The primary outcome was readmission within 30 days post-discharge. Multilevel, multivariable logistic regression modelling was used to compare outcomes for those operated on as day-cases and those with an overnight stay after adjusting for demographic, frailty, comorbidity and procedural covariates. RESULTS: Data were available for 49 223 patients operated on across 129 NHS hospital trusts. In trusts operating on more than 50 patients in the study period, rates of day-case surgery varied from 20.6% to 100%. Nationally, rates of day-case surgery increased from 64.0% in the financial year 2014/2015 to 78.7% in 2018/2019. Day-case patients had lower rates of 30-day emergency readmission (odds ratio 0.71, 95% confidence interval 0.62 to 0.81). Outcomes for patients operated on in trusts with ≥80% day-case rates compared with patients operated on in trusts with <50% rates of day-case surgery were similar. CONCLUSIONS: Our data support the view that ESS can safely be performed as day-case surgery in most cases, although it will not be suitable for all patients. There appears to be scope to increase rates of day-case ESS in some hospital trusts in England.

OBJECTIVES: HIV-associated neurocognitive disorders (HANDs) are prevalent in older people living with HIV (PLWH) worldwide. HAND prevalence and incidence studies of the newly emergent population of combination antiretroviral therapy (cART)-treated older PLWH in sub-Saharan Africa are currently lacking. We aimed to estimate HAND prevalence and incidence using robust measures in stable, cART-treated older adults under long-term follow-up in Tanzania and report cognitive comorbidities. DESIGN: Longitudinal study. PARTICIPANTS: A systematic sample of consenting HIV-positive adults aged ≥50 years attending routine clinical care at an HIV Care and Treatment Centre during March-May 2016 and followed up March-May 2017. MEASUREMENTS: HAND by consensus panel Frascati criteria based on detailed locally normed low-literacy neuropsychological battery, structured neuropsychiatric clinical assessment, and collateral history. Demographic and etiological factors by self-report and clinical records. RESULTS: In this cohort (n = 253, 72.3% female, median age 57), HAND prevalence was 47.0% (95% CI 40.9-53.2, n = 119) despite well-managed HIV disease (Mn CD4 516 (98-1719), 95.5% on cART). Of these, 64 (25.3%) were asymptomatic neurocognitive impairment, 46 (18.2%) mild neurocognitive disorder, and 9 (3.6%) HIV-associated dementia. One-year incidence was high (37.2%, 95% CI 25.9 to 51.8), but some reversibility (17.6%, 95% CI 10.0-28.6 n = 16) was observed. CONCLUSIONS: HAND appear highly prevalent in older PLWH in this setting, where demographic profile differs markedly to high-income cohorts, and comorbidities are frequent. Incidence and reversibility also appear high. Future studies should focus on etiologies and potentially reversible factors in this setting.

BACKGROUND: Older adults have worse outcomes following hospitalization with COVID-19, but within this group there is substantial variation. Although frailty and comorbidity are key determinants of mortality, it is less clear which specific manifestations of frailty and comorbidity are associated with the worst outcomes. OBJECTIVE: We aimed to identify the key comorbidities and domains of frailty that were associated with in-hospital mortality in older patients with COVID-19 using models developed for machine learning algorithms. METHODS: This was a retrospective study that used the Hospital Episode Statistics administrative data set from March 1, 2020, to February 28, 2021, for hospitalized patients in England aged 65 years or older. The data set was split into separate training (70%), test (15%), and validation (15%) data sets during model development. Global frailty was assessed using the Hospital Frailty Risk Score (HFRS) and specific domains of frailty were identified using the Global Frailty Scale (GFS). Comorbidity was assessed using the Charlson Comorbidity Index (CCI). Additional features employed in the random forest algorithms included age, sex, deprivation, ethnicity, discharge month and year, geographical region, hospital trust, disease severity, and International Statistical Classification of Disease, 10th Edition codes recorded during the admission. Features were selected, preprocessed, and input into a series of random forest classification algorithms developed to identify factors strongly associated with in-hospital mortality. Two models were developed; the first model included the demographic, hospital-related, and disease-related items described above, as well as individual GFS domains and CCI items. The second model was similar to the first but replaced the GFS domains and CCI items with the HFRS as a global measure of frailty. Model performance was assessed using the area under the receiver operating characteristic (AUROC) curve and measures of model accuracy. RESULTS: In total, 215,831 patients were included. The model using the individual GFS domains and CCI items had an AUROC curve for in-hospital mortality of 90% and a predictive accuracy of 83%. The model using the HFRS had similar performance (AUROC curve 90%, predictive accuracy 82%). The most important frailty items in the GFS were dementia/delirium, falls/fractures, and pressure ulcers/weight loss. The most important comorbidity items in the CCI were cancer, heart failure, and renal disease. CONCLUSIONS: The physical manifestations of frailty and comorbidity, particularly a history of cognitive impairment and falls, may be useful in identification of patients who need additional support during hospitalization with COVID-19.
