RESUMO
OBJECTIVE: The aim of this study was to quantify the recent and historical extent of regional variation in revascularization and amputation for peripheral artery disease (PAD). METHODS: This was a repeated cross-sectional analysis of all Ontarians aged 40 years or greater between 2002 and 2019. The co-primary outcomes were revascularization (endovascular or open) and major (above-ankle) amputation for PAD. For each of 14 health care administrative regions, rates per 100,000 person-years (PY) were calculated for 6-year time periods from the fiscal years 2002 to 2019. Rates were directly standardized for regional demographics (age, sex, income) and comorbidities (congestive heart failure, diabetes, chronic obstructive pulmonary disease, chronic kidney disease). The extent of regional variation in revascularization and major amputation rates for each time period was quantified by the ratio of 90th over the 10th percentile (PRR). RESULTS: In 2014 to 2019, there were large differences across regions in demographics (rural living [range, 0%-39.4%], lowest neighborhood income quintile [range, 10.1%-25.5%]) and comorbidities (diabetes [range, 14.2%-22.0%], chronic obstructive pulmonary disease [range, 7.8%-17.9%]), and chronic kidney disease [range, 2.1%-4.0%]. Standardized revascularization rates ranged across regions from 52.6 to 132.6/100,000 PY and standardized major amputation rates ranged from 10.0 to 37.7/100,000 PY. The extent of regional variation was large (PRR ≥2.0) for both revascularization and major amputation. From 2002-2004 to 2017-2019, the extent of regional variation increased from moderate to large for revascularization (standardized PRR, 1.87 to 2.04) and major amputation (standardized PRR, 1.94 to 3.07). CONCLUSIONS: Significant regional differences in revascularization and major amputation rates related to PAD remain after standardizing for regional differences in demographics and comorbidities. These differences have not improved over time.

AIM/HYPOTHESIS: To describe the influence of diabetes on temporal changes in rates of lower extremity revascularisation and amputation for peripheral artery disease (PAD) in Ontario, Canada. METHODS: In this population-based repeated cross-sectional study, we calculated annual rates of lower extremity revascularisation (open or endovascular) and amputation (toe, foot or leg) related to PAD among Ontario residents aged ≥40 years between 2002 and 2019. Annual rate ratios (relative to 2002) adjusted for changes in diabetes prevalence alone, as well as fully adjusted for changes in demographics, diabetes and other comorbidities, were estimated using generalized estimating equation models to model population-level effects while accounting for correlation within units of observation. RESULTS: Compared with 2002, the Ontario population in 2019 exhibited a significantly higher prevalence of diabetes (18% vs. 10%). Between 2002 and 2019, the crude rate of revascularisation increased from 75.1 to 90.7/100,000 person-years (unadjusted RR = 1.10, 95% CI = 1.07-1.13). However, after adjustment, there was no longer an increase in the rate of revascularisation (diabetes-adjusted RR = 0.98, 95% CI = 0.96-1.01, fully-adjusted RR = 0.94, 95% CI = 0.91-0.96). The crude rate of amputation decreased from 2002 to 2019 from 49.5 to 45.4/100,000 person-years (unadjusted RR = 0.78, 95% CI = 0.75-0.81), but was more pronounced after adjustment (diabetes-adjusted RR = 0.62, 95% CI = 0.60-0.64; fully-adjusted RR = 0.58, 95% CI = 0.56-0.60). CONCLUSIONS/INTERPRETATION: Diabetes prevalence rates strongly influenced rates of revascularisation and amputation related to PAD. A decrease in amputations related to PAD over time was attenuated by rising diabetes prevalence rates.

OBJECTIVE: Our goal was to describe contemporary management and inhospital mortality associated with blunt thoracic aortic intimal tears (IT) within the American College of Surgeons Trauma Quality Improvement Program. SUMMARY BACKGROUND DATA: The evidence basis for nonoperative expectant management of traumatic iT of the thoracic aorta remains weak. METHODS: All adult patients with a thoracic aortic IT following blunt trauma were captured from Level I and II North American Centers enrolled in Trauma Quality Improvement Program from 2010 to 2017. For each patient, we extracted demographics, injury characteristics, the timing and approach of thoracic aortic repair and in-hospital mortality. Mortality attributable to IT was calculated by comparing IT patients to a propensity-score matched control cohort of severely injured blunt trauma patients without aortic injury. RESULTS: There were 2203 IT patients across 315 facilities. Injury most often resulted from motor vehicle collision (75%). A total of 758 patients (34%) underwent operative management, with 93% (N = 708) of repairs performed via an endovascular approach. Median time to surgery was 11âhours (IQR 4- 40). The frequency of operative management was higher in patients without traumatic brain injury (TBI) (35%, N = 674) compared to those with TBI (29%, N = 84) (P = 0.024). Compared to severely injured blunt trauma patients without aortic injury, ITwas not associated with additional in-hospital mortality (10.7% for IT vs 11.7% for no IT, absolute risk difference: -1.0%, 95% CI: -2.9% to 0.8%). CONCLUSIONS: The majority of blunt thoracic IT are managed nonoperatively and IT does not confer additional in-hospital mortality risk. Future studies should focus on the risk of injury progression.

OBJECTIVE: Vascular surgery has evolved with increasing use of endovascular therapies and a decline in open surgery. The influence of these changes, in addition to a new vascular surgery training program introduced in 2012, on case volumes of vascular trainees is not known. We sought to evaluate trends in operative case volumes of Canadian vascular surgery trainees. METHODS: A survey was administered to graduates of the Canadian Royal College-accredited Vascular Fellowships (VFs) and Integrated Vascular Surgery Residency (IVSR) programs (2007-2019) to record cases performed during their final 2 years of training. Procedures of interest were open abdominal aortic aneurysm (oAAA) repair, open thoracic/thoracoabdominal aortic (oTAA/TAAA) repair, lower extremity bypass (LEB), carotid endarterectomy (CEA), lower extremity endovascular intervention (LEEI), and endovascular abdominal, advanced, and thoracic aortic repair (EVAR, aEVAR, and TEVAR). Case volumes were analyzed overall, and by graduation year, type of training program, and resident demographics. RESULTS: A total of 60 participants (10% female) from all the 10 Canadian training institutions responded (response rate, 63%). There was a declining trend in overall procedures performed since the introduction of IVSR in 2012 (median, 427 [interquartile range (IQR), 304-496] in 2007-2012 vs median, 342 [IQR, 279-405] in 2013-2019; P = .055), driven by a significant decline in open vascular surgery cases (median, 273 [IQR, 221-339] in 2007-2012 vs median, 156 [IQR, 128-181] in 2013-2019; P = .001). Case volumes of oAAA, LEB, and CEA declined by 44%, 40%, and 45%, respectively. Compared with vascular fellows, IVSR residents logged â¼2.5 times more aEVARs (median, 8; IQR, 2-11 vs median, 19; IQR, 8-27; P = .001) and â¼1.5 times more LEEIs (median, 60; IQR, 40-99 vs median, 93; IQR, 69-120; P = .018). Trainees were most confident (range, 90%-100%) in performing oAAA, EVAR, LEB, LEEI, and CEA after training, and least confident in performing oTAA/TAAA and aEVAR (20% and 49% confidence, respectively). CONCLUSIONS: Operative case volumes of Canadian vascular surgery trainees since the introduction of IVSR program in 2012 have decreased, driven by declining exposure to open cases. However, trainees continue to receive adequate operative exposure to perform most standard vascular procedures confidently upon graduation.

PURPOSE: To estimate the positive predictive value of diagnosis and procedure codes for open and endovascular revascularization for peripheral artery disease (PAD) in Ontario administrative databases. METHODS: We conducted a retrospective validation study using population-based Ontario administrative databases (2005-2019) to identify a random sample of 600 patients who underwent revascularization for PAD at two academic centres, based on ICD-10 diagnosis codes and Canada Classification of Health Intervention procedure codes. Administrative data coding was compared to the gold standard diagnosis (PAD vs. non-PAD) and revascularization approach (open vs. endovascular) extracted through blinded hospital chart re-abstraction. Positive predictive values and 95% confidence intervals were calculated. Combinations of procedure codes with or without supplemental physician claims codes were evaluated to optimize the positive predictive value. RESULTS: The overall positive predictive value of PAD diagnosis codes was 87.5% (84.6%-90.0%). The overall positive predictive value of revascularization procedure codes was 94.3% (92.2%-96.0%), which improved through supplementation with physician fee claim codes to 98.1% (96.6%-99.0%). Algorithms to identify individuals revascularized for PAD had combined positive predictive values ranging from 82.8% (79.6%-85.8%) to 95.7% (93.5%-97.3%). CONCLUSION: Diagnosis and procedure codes with or without physician claims codes allow for accurate identifi-cation of individuals revascularized for PAD in Ontario administrative databases.

PURPOSE: To estimate the positive predictive value (PPV) of Canadian ICD-10 diagnostic coding for the identification of hospitalization related to a diabetic foot ulcer (DFU). METHODS: Hospitalizations related to a neuropathic and/or ischemic DFU were identified from the Discharge Abstract Database (DAD) records of a single Canadian tertiary care hospital between April 1, 2002 and March 31, 2019. The first coding approach required a most responsible diagnosis (MRDx) code for diabetes-specific foot ulceration or gangrene (DSFUG group). Three alternative coding approaches were also considered: MRDx code for lower-limb osteomyelitis (osteomyelitis group); lower-limb ulceration (LLU group); or lower-limb atherosclerotic gangrene (atherosclerosis group)-each in conjunction with a non-MRDx DSFUG code on the same DAD record. From all eligible DAD records, random samples were drawn for each coding group. DAD records were independently compared by a masked reviewer who manually abstracted data from the entire hospital record (reference standard). The PPV and 95% CI were generated. RESULTS: Out of 1,460 hospitalizations, a total of 300, 50, 33 and seven records were included from the DSFUG, osteomyelitis, LLU and atherosclerosis samples, respectively. Compared to the reference standard, the PPV for all 390 records was 88.5% (95% CI 84.9 to 91.5). The DSFUG group had the highest PPV (90.0%, 95% CI 86.0 to 93.2), followed by the atherosclerosis (85.7%, 95% CI 42.1 to 99.6), LLU (84.9%, 95% CI 68.1 to 94.9) and osteomyelitis (82.0%, 95% CI 68.6 to 91.4) groups. CONCLUSION: Based on data from a Canadian tertiary care hospital, the specified coding algorithms can be used to identify and study the management and outcomes of people hospitalized with a DFU in Ontario.

Background: Recent evidence suggests that home care nursing is variably prescribed after vascular surgery, and may reduce emergency department visits and hospital readmissions. We therefore sought to characterize the indications for home care nursing following vascular surgery from the surgeon's perspective. Methods: An online survey was distributed to the 141 members of the Canadian Society for Vascular Surgery with questions related to home care nursing after carotid endarterectomy (CEA), endovascular aortic aneurysm repair (EVAR), open abdominal aortic aneurysm (AAA) repair and open or hybrid revascularization for peripheral arterial disease (PAD). We included all questionnaires in our analysis; the frequency denominator changes according to the number of respondents who completed each survey item. Results: There were 46 survey respondents (33% of 141) from across the country. A total of 28 (62% of 45) worked in a teaching hospital. Home care nursing was routinely prescribed by 5%, 10%, 31% and 41% of respondents following CEA, EVAR, open AAA repair and open or hybrid revascularization for PAD, respectively. Across all procedure types, the same procedure-related criteria were most often deemed to warrant a prescription for home care nursing: surgical site infection, wound complications (e.g., open wound, lymphatic leak) and use of negative-pressure wound therapy. Across all procedure types, lack of social support, physical frailty and cognitive impairment were most frequently identified as patient-specific considerations for prescribing home care nursing. Few respondents reported restrictions or standards that informed their prescribing practice. Conclusion: Most surgeon respondents agreed on the indications for home care nursing after vascular surgery. However, evidence-based standards to guide patient selection for home care nursing after vascular surgery are needed.
Contexte: Selon des données récentes, les soins infirmiers à domicile sont prescrits aléatoirement après la chirurgie vasculaire, et pourraient réduire les consultations aux urgences et les réhospitalisations. Nous avons donc voulu caractériser les indications des soins infirmiers à domicile après la chirurgie vasculaire, du point de vue des chirurgiens. Méthodes: Nous avons transmis un sondage en ligne aux 141 membres de la Société canadienne de chirurgie vasculaire (SCCV); les questions portaient sur les soins infirmiers à domicile après l'endartériectomie carotidienne, la réparation endovasculaire de l'anévrisme de l'aorte, la réparation chirurgicale de l'anévrisme de l'aorte abdominale (AAA) et la revascularisation chirurgicale ou hybride de la maladie artérielle périphérique (MAP). Nous avons inclus tous les questionnaires dans notre analyse; le dénominateur de fréquence change en fonction du nombre de répondants qui ont répondu à chaque élément du sondage. Résultats: Quarante-six chirurgiens des quatre coins du pays ont répondu (33 % des 141 membres de la SCCV). En tout, 28 (62 % des of 45) travaillaient dans un établissement universitaire. Les soins infirmiers à domicile étaient prescrits d'emblée par 5 %, 10 %, 31 % et 41 % des répondants suite à l'endartériectomie carotidienne, la réparation endovasculaire de l'anévrisme de l'aorte, la chirurgie pour AAA et la revascularisation chirurgicale ou hybride de la MPA, respectivement. Pour tous les types d'interventions, les mêmes critères liés aux interventions ont semblé justifier la prescription de soins infirmiers à domicile : infection de plaie, complications au niveau de la plaie (p. ex., plaie ouverte, plaie exsudative) et traitement de plaie par pression négative. Pour tous les types d'intervention, l'absence de soutien social, la fragilité physique et le déclin cognitif ont le plus souvent été identifiés parmi les critères spécifiques aux patients pour la prescription de soins infirmiers à domicile. Peu de répondants ont mentionné de possibles restrictions ou normes sur lesquelles fonder leurs habitudes de prescription à ce chapitre. Conclusion: La plupart des chirurgiens participants se sont entendus sur les indications des soins infirmiers à domicile après la chirurgie vasculaire. Il faudrait toutefois établir des normes fondées sur des données probantes pour guider la sélection des patients candidats aux soins infirmiers à domicile après la chirurgie vasculaire.

OBJECTIVE: The objective was to characterize the growing body of literature regarding nonoperative management of blunt thoracic aortic injury (BTAI). METHODS: A systematic search of MedLine, Embase, and Cochrane Central was completed to identify original articles reporting injury characteristics and outcomes in patients with BTAI managed nonoperatively during their index hospitalization. Article title and abstract screening, full-text review, and data abstraction were performed in duplicate, with discrepancies resolved by a third reviewer. The quality of each study was evaluated using the Oxford Centre for Evidence-Based Levels of Evidence. RESULTS: Of 2162 identified studies, 74 were included and reported on 8606 patients with BTAI who were managed nonoperatively between 1970 and 2016. Only one study was prospective. The median nonoperative sample size per study was 11 patients. The characterization of aortic injury grade differed across studies. Follow-up varied widely from 1 day to 118 months. Injury healing or improvement on follow-up imaging occurred in 34% (226 of 673 patients; reported in 37 studies), most often in the context of grade I intimal injury. Injury progression or requirement for a thoracic endovascular aneurysm repair for injury progression was 7.6% (66 of 873 patients; reported in 46 studies). A total of 37 studies reported aortic-related death, with an overall rate of 4.5% (37 of 827 patients) and a rate of 1% in grade I and II injuries (1 of 153 patients) and 18% in grade III and IV (9 of 50 patients). CONCLUSIONS: An increasing number of reports support nonoperative management of grade I intimal injury, consistent with Society for Vascular Surgery guidelines. However, a retrospective interpretation of the determinants of management, heterogeneous injury characterization, and variable follow-up remain major limitations to the informed use of nonoperative management across all BTAI grades.

The field of vascular surgery is in constant evolution. Administrative data and registries can provide important contemporary evidence to inform clinical decision making and delivery of health services. This review outlines some important considerations for retrospective studies using administrative health databases and registries. First, these data sources have advantages (e.g., real-world applicability, timely data access, and relatively lower research cost) and disadvantages (e.g., potential missing data, selection bias, and confounding bias) that may be more or less relevant to different administrative databases or registries. Second, a framework to guide data source selection and provide a summary of frequently used data sources in vascular surgery research is discussed. Third, a retrospective study design warrants planned exposure, outcome, and covariate definitions and, when studying an exposure-outcome association, careful consideration of confounders through direct acyclic graphs. Finally, investigators must plan the most appropriate analytic approach, and we distinguish descriptive, explanatory, and predictive analyses.

OBJECTIVE: Current EAST guidelines recommend against routine carotid intervention for patients with blunt carotid artery injury (BCI), but offer limited information on its role for BCI patients presenting with neurological deficit. Our goal was to describe the contemporary management and outcomes of patients presenting with BCI and neurological deficit unrelated to head injury. METHODS: We identified all adults who sustained a BCI between 2010 and 2017 in the American College of Surgeons Trauma Quality Improvement Program. We extracted patient demographics, injury characteristics (carotid and non-carotid), as well as the frequency, timing and approach of carotid intervention. Presence of neurological deficit unrelated to head injury at presentation was determined using Abbreviated Injury Scale codes. The main outcomes were in-hospital mortality and home discharge. Patients with and without neurological deficit at presentation were compared through multivariable logistic regression modeling. Among those with neurological deficit at presentation, the associations between carotid intervention (open or endovascular) and the outcomes were also assessed through multivariable logistic regression. RESULTS: We identified 5,788 patients with BCI of whom 383 (7%) presented with neurological deficit unrelated to head injury. Among the 296 patients (5%) who underwent carotid intervention, 36 (12%) had presented with neurological deficit unrelated to head injury. Interventions were most often endovascular (68% [200/296]) and within a median time of 32 h (IQR 5-203). In-hospital mortality was 16% (918/5,788), and in-hospital stroke prevalence was 6% (336/5,788). When comparing patients with and without neurological deficit at presentation, those with deficits were more frequently managed with an intervention. After adjustment, the likelihood of mortality was higher (OR [95% CI] = 2.16 [1.63-2.85]) and the likelihood of home discharge lower (OR [95% CI] = 0.29 [0.21-0.40]) among patients presenting with neurological deficit. Among those with neurological deficit, carotid intervention was positively associated with home discharge (OR [95% CI] = 2.96 [1.21-7.23]), but not with in-hospital mortality (OR [95% CI] = 0.87 [0.36-2.10]). Results were similar in the subgroup of patients with isolated BCI (2,971/5,788). CONCLUSIONS: Intervention in BCI patients presenting with neurological deficit may contribute to a greater likelihood of home discharge but not reduced in-hospital mortality.

Importance: Deferred diabetic foot screening and delays in timely care of acute foot complications during the COVID-19 pandemic may have contributed to an increase in limb loss. Objective: To evaluate the association of the COVID-19 pandemic with diabetes-related care measures, foot complications, and amputation. Design, Setting, and Participants: This population-based cohort study included all adult residents of Ontario, Canada, with diabetes and compared the rates of selected outcomes from January 1, 2020, to February 23, 2021, vs January 1, 2019, to February 23, 2020. Main Outcomes and Measures: Comprehensive in-person diabetes care assessment, including foot examination; hemoglobin A1c (HbA1c) measurement; emergency department visit or hospitalization for diabetic foot ulceration, osteomyelitis, or gangrene; lower extremity open or endovascular revascularization; minor (toe or partial-foot) amputation; and major (above-ankle) leg amputation. Rates and rate ratios (RRs) comparing 2020-2021 vs 2019-2020 for each measure were calculated for 10-week periods, anchored relative to onset of the pandemic on March 11, 2020 (11th week of 2020). Results: On March 11, 2020, the study included 1â¯488â¯605 adults with diabetes (median [IQR] age, 65 [55-74] years; 776â¯665 [52.2%] men), and on March 11, 2019, the study included 1â¯441â¯029 adults with diabetes (median [IQR] age, 65 [55-74] years; 751â¯459 [52.1%] men). After the onset of the pandemic, rates of major amputation in 2020-2021 decreased compared with 2019-2020 levels. The RR for the prepandemic period from January 1 to March 10 was 1.05 (95% CI, 0.88-1.25), with RRs in the pandemic periods ranging from 0.86 (95% CI, 0.72-1.03) in May 20 to July 28 to 0.95 (95% CI, 0.80-1.13) in October 7 to December 15. There were no consistent differences in demographic characteristics or comorbidities of patients undergoing amputation in the 2020-2021 vs 2019-2020 periods. Rates of comprehensive in-person diabetes care assessment and HbA1c measurement declined sharply and remained below 2019-2020 levels (eg, in-person assessment, March 11 to May 19: RR, 0.28; 95% CI, 0.28-0.28). The rates of emergency department visits (eg, March 11 to May 19: RR, 0.67; 95% CI, 0.61-0.75), hospitalization (eg, March 11 to May 19: RR, 0.77; 95% CI, 0.68-0.87), open revascularization (eg, March 11 to May 19: RR, 0.66; 95% CI, 0.56-0.79), endovascular revascularization (March 11 to May 19: RR, 0.70; 95% CI, 0.61-0.81), and minor amputation (March 11 to May 19: RR, 0.70; 95% CI, 0.60-0.83) initially dropped but recovered to 2019-2020 levels over the study period. Conclusions and Relevance: In this population-based cohort study, disruptions in care related to the COVID-19 pandemic were not associated with excess leg amputations among people living with diabetes. As the pandemic ends, improved prevention and treatment of diabetic foot complications will be necessary to maintain these positive results.

We sought to assess temporal trends in peripheral artery disease (PAD)-related hospitalization rates in Ontario. Trends in quarterly rates of PAD hospitalization per 100,000 Ontarians between 2006 and 2019 were assessed using autocorrelated linear regression. Stratified analyses according to age, sex, and most responsible diagnosis code type (with vs without diabetes-specific PAD codes) were performed. From 2006 to 2019, overall PAD hospitalizations did not decrease significantly when diabetes-specific codes were included. A significant decrease was observed among women and those older than 65 years old. Future studies of PAD epidemiology and outcomes using administrative data should include diabetic angiopathy.

OBJECTIVE: Many studies have analysed gender bias in academic medicine; however, no comprehensive synthesis of the literature has been performed. We conducted a pooled analysis of the difference in the proportion of men versus women with full professorship among academic physicians. DESIGN: Systematic review and meta-analysis. DATA SOURCES: MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Education Resources Information Center and PsycINFO were searched from inception to 3 July 2020. STUDY SELECTION: All original studies reporting faculty rank stratified by gender worldwide were included. DATA EXTRACTION AND SYNTHESIS: Study screening, data extraction and quality assessment were performed by two independent reviewers, with a third author resolving discrepancies. Meta-analysis was conducted using random-effects models. RESULTS: Our search yielded 5897 articles. 218 studies were included with 991 207 academic physician data points. Men were 2.77 times more likely to be full professors (182 271/643 790 men vs 30 349/251 501 women, OR 2.77, 95% CI 2.57 to 2.98). Although men practised for longer (median 18 vs 12 years, p<0.00002), the gender gap remained after pooling seven studies that adjusted for factors including time in practice, specialty, publications, h-index, additional PhD and institution (adjusted OR 1.83, 95% CI 1.04 to 3.20). Meta-regression by data collection year demonstrated improvement over time (p=0.0011); however, subgroup analysis showed that gender disparities remain significant in the 2010-2020 decade (OR 2.63, 95% CI 2.48 to 2.80). The gender gap was present across all specialties and both within and outside of North America. Men published more papers (mean difference 17.2, 95% CI 14.7 to 19.7), earned higher salaries (mean difference $33 256, 95% CI $25 969 to $40 542) and were more likely to be departmental chairs (OR 2.61, 95% CI 2.19 to 3.12). CONCLUSIONS: Gender inequity in academic medicine exists across all specialties, geographical regions and multiple measures of success, including academic rank, publications, salary and leadership. Men are more likely than women to be full professors after controlling for experience, academic productivity and specialty. Although there has been some improvement over time, the gender disparity in faculty rank persists. PROSPERO REGISTRATION NUMBER: CRD42020197414.
