Impact of Social Risk Screening on Discharge Care Processes and Postdischarge Outcomes: A Pragmatic Mixed-Methods Clinical Trial During the COVID-19 Pandemic.

BACKGROUND: Social risk screening during inpatient care is required in new CMS regulations, yet its impact on inpatient care and patient outcomes is unknown. OBJECTIVES: To evaluate whether implementing a social risk screening protocol improves discharge processes, patient-reported outcomes, and 30-day service use. RESEARCH DESIGN: Pragmatic mixed-methods clinical trial. SUBJECTS: Overall, 4130 patient discharges (2383 preimplementation and 1747 postimplementation) from general medicine and surgical services at a 528-bed academic medical center in the Intermountain United States and 15 attending physicians. MEASURES: Documented family interaction, late discharge, patient-reported readiness for hospital discharge and postdischarge coping difficulties, readmission and emergency department visits within 30 days postdischarge, and coded interviews with inpatient physicians. RESULTS: A multivariable segmented regression model indicated a 19% decrease per month in odds of family interaction following intervention implementation (OR=0.81, 95% CI=0.76-0.86, P<0.001), and an additional model found a 32% decrease in odds of being discharged after 2 pm (OR=0.68, 95% CI=0.53-0.87, P=0.003). There were no postimplementation changes in patient-reported discharge readiness, postdischarge coping difficulties, or 30-day hospital readmissions, or ED visits. Physicians expressed concerns about the appropriateness, acceptability, and feasibility of the structured social risk assessment. CONCLUSIONS: Conducted in the immediate post-COVID timeframe, reduction in family interaction, earlier discharge, and provider concerns with structured social risk assessments likely contributed to the lack of intervention impact on patient outcomes. To be effective, social risk screening will require patient/family and care team codesign its structure and processes, and allocation of resources to assist in addressing identified social risk needs.

Decision making in the frail vascular surgery patient: A scoping review.

Increasing evidence highlights the adverse impact of frailty and reduced physiologic reserve on surgical outcomes. Therefore, identification of frailty is essential for older adults being evaluated for vascular surgery procedures. Numerous frailty assessment tools are available to quantify the level of frailty and assist in preoperative decision making for these older patients. This review evaluates traditional and novel frailty metrics for their scientific validation, limitations, and clinical utility in vascular surgery decision-making.

Increased Risk of Acute Aortic Events following COVID-19 and Influenza Respiratory Viral Infections.

BACKGROUND: Acute respiratory viral infections have been associated with an increased incidence of adverse cardiovascular events. However, it is unclear whether severe respiratory viral infections are associated with an increased risk of acute aortic syndromes (AAS). This study was designed to assess whether Coronavirus disease 2019 (COVID-19) and Influenza illnesses are associated with an increased incidence of subsequent AAS in the US population. METHODS: We used the MarketScan database (2011-2021) to identify patients 18-99 years of age without prior diagnosis of aortic pathology who were diagnosed with COVID-19 or Influenza. Identified patients were matched 1:1 by age and sex to control patients without COVID-19 or Influenza. The primary outcome was incidence of AAS (dissection, intramural hematoma, penetrating aortic ulcer, or aneurysm rupture) within 180-days of a viral infection. The association between infection and risk of developing an AAS was analyzed using multivariate Cox proportional hazards models. RESULTS: We identified 1,775,698 patients, including 779,229 (44%) with mild COVID-19, 42,141 (2%) with severe COVID-19, and 66,479 (4%) with Influenza that were matched to 887,849 (50%) control patients without COVID-19 or Influenza illnesses. A total of 164 patients experienced AAS within 6-months after diagnosis, which was highest among those after severe COVID-19. The predicted incidence of AAS was significantly higher among patients after severe COVID-19 (14.1 events/100,000 person-years), mild COVID-19 (13.3 events/100,000), and influenza (13.3 events/100,000) when compared to control patients (2.6 events/100,000). In risk-adjusted Cox regression models, severe COVID-19 (HR:5.4, 95% CI:2.8-10.4; P < 0.01), mild COVID-19 (HR:5.1, 95% CI:3.3-7.7; P < 0.01) and influenza (HR:5.1, 95% CI:2.6-9.7; P < 0.01) diagnoses were associated with a significantly increased risk of AAS within 180-days when compared to matched controls. CONCLUSIONS: There is an increased risk of developing acute aortic event in the months following illness with Influenza or COVID-19. These data highlight the need to closely monitor at-risk patients following a viral respiratory infection.

A transitional pain management program is associated with reduced opioid dependence after major shoulder surgery.

BACKGROUND: Overprescription of opioids in the United States increases risks of opioid dependence, overdose, and death. Increased perioperative and postoperative opioid use during orthopedic shoulder surgery is a significant risk factor for long-term opioid dependence. The authors hypothesized that a multidisciplinary perioperative pain management program (Transitional Pain Service [TPS]) for major shoulder surgery would lead to a reduced amount of opioids required postoperatively. METHODS: A TPS was implemented at a Veterans Affairs Medical Center focused on nonopioid pain management and cessation support. Opioid consumption during the implementation of the TPS was compared to a historical cohort. All patients undergoing total shoulder arthroplasty (TSA) or rotator cuff repair (RCR) were included. The primary outcome was the proportion of patients continuing opioid use at 90 days postoperatively. Secondary outcomes included postoperative pain scores, time to opioid cessation, and median opioid tablets consumed at 90 days. A multivariable model was developed to predict total opioid use at 90 days postoperatively. Kaplan-Meier curves were calculated for time to opioid cessation. RESULTS: The TPS group demonstrated decreased persistent opioid use at 90 days postdischarge (12.6% vs. 28.6%; P = .018). Independent predictors associated with increased total opioid tablet prescriptions at 90 days included length of stay (ß = 19.17), anxiety diagnosis (ß = 37.627), and number of tablets prescribed at discharge (ß = 1.353). TSA was associated with decreased 90-day opioid utilization (ß = -32.535) when compared to RCR. Median time to cessation was shorter in TSA (6 days) when compared with RCR (8 days). Pain scores were reduced compared with population mean by postdischarge day 2 for TSA and by postdischarge day 7 for RCR. Median number of postdischarge opioid tablets (oxycodone 5 mg) consumed under TPS management was 25 in both RCR and TSA surgery groups (180 morphine milligram equivalents). DISCUSSION AND CONCLUSIONS: This study demonstrates that a TPS reduces the amount of opioid use of patients undergoing shoulder arthroplasty or cuff repair at 90 days when compared with a historical control. Multivariable regression indicated that fewer opioid tablets at discharge was a modifiable factor that may aid in reducing opioid consumption and that anxiety diagnosis, increased length of stay, and cuff repair surgery were other factors independently associated with increased opioid consumption. These data will assist surgeons in counseling patients, setting narcotic use expectations, and minimizing overprescribing. Use of a similar multidisciplinary perioperative pain management program may greatly reduce opioid overprescriptions nationally.

Sex Differences in Patient-Reported Depression Following Vascular Surgery Procedures.

INTRODUCTION: Female patients frequently experience worse clinical outcomes than male patients after undergoing vascular surgery procedures. However, it is unclear whether these sex-based disparities also impact mental health outcomes. This study was designed to investigate sex differences in patient-reported outcome measures of depression for patients undergoing vascular surgery. METHODS: We retrospectively analyzed 107 patients (73 males and 34 females) who underwent vascular surgery procedures between January 2016 and April 2023. These patients completed a Patient-Reported Outcome Measurement Information System (PROMIS) Item Bank v1.0-Depression assessment 90 d before surgery and at least once after surgery. After stratifying patients by sex, we analyzed changes in PROMIS depression scores using a multiple mixed-effects linear regression model. Then, logistic regression was used to compare the proportion of patients who achieved a clinically meaningful difference in PROMIS depression score within 15 mo after surgery. RESULTS: There was no significant difference between female and male patients among rates of complications, length of hospital stay, or rates of nonhome discharge. However, female sex was associated with significantly improved PROMIS depression scores after surgery compared to male sex (P = 0.034). Furthermore, female patients were over 3-fold more likely than male patients to reach the minimal clinically important difference threshold for improvement in PROMIS depression scores (odds ratio 4.66, 95% confidence interval 1.39-15.61). CONCLUSIONS: These results suggest that female sex is associated with improved patient-reported measures of depression after undergoing vascular surgery. Clinicians should consider these mental health benefits when evaluating female patients for vascular interventions.

Long-term patient-reported outcomes among patients undergoing revascularization vs medical therapy for intermittent claudication.

OBJECTIVE: Society for Vascular Surgery guidelines recommend revascularization for patients with intermittent claudication (IC) if it can improve patient function and quality of life. However, it is still unclear if patients with IC achieve a significant functional benefit from surgery compared with medical management alone. This study examines the relationship between IC treatment modality (operative vs nonoperative optimal medical management) and patient-reported outcomes for physical function (PROMIS-PF) and satisfaction in social roles and activities (PROMIS-SA). METHODS: We identified patients with IC who presented for index evaluation in a vascular surgery clinic at an academic medical center between 2016 and 2021. Patients were stratified based on whether they underwent a revascularization procedure during follow-up vs continued nonoperative management with medication and recommended exercise therapy. We used linear mixed-effect models to assess the relationship between treatment modality and PROMIS-PF, PROMIS-SA, and ankle-brachial index (ABI) over time, clustering among repeat patient observations. Models were adjusted for age, sex, diabetes, Charlson Comorbidity Index, Clinical Frailty Score, tobacco use, and index ABI. RESULTS: A total of 225 patients with IC were identified, of which 40% (n = 89) underwent revascularization procedures (42% bypass; 58% peripheral vascular intervention) and 60% (n = 136) continued nonoperative management. Patients were followed up to 6.9 years, with an average follow-up of 5.2 ± 1.6 years. Patients who underwent revascularization were more likely to be clinically frail (P = .03), have a lower index ABI (0.55 ± 0.24 vs 0.72 ± 0.28; P < .001), and lower baseline PROMIS-PF score (36.72 ± 8.2 vs 40.40 ± 6.73; P = .01). There were no differences in patient demographics or medications between treatment groups. Examining patient-reported outcome trends over time; there were no significant differences in PROMIS-PF between groups, trends over time, or group differences over time after adjusting for covariates (P = .07, P = .13, and P =.08, respectively). However, all patients with IC significantly increased their PROMIS-SA over time (adjusted P = .019), with patients managed nonoperatively more likely to have an improvement in PROMIS-SA over time than those who underwent revascularization (adjusted P = .045). CONCLUSIONS: Patient-reported outcomes associated with functional status and satisfaction in activities are similar for patients with IC for up to 7 years, irrespective of whether they undergo treatment with revascularization or continue nonoperative management. These findings support conservative long-term management for patients with IC.

Recurrence of severe diverticulitis is associated with age and birth decade.

BACKGROUND: The risk of recurrence is an important consideration when deciding to treat patients medically or with elective colectomy after recovery from diverticulitis. It is unclear whether age is associated with recurrence. This study aimed to examine the relationship between age and the risk of recurrent diverticulitis while considering important epidemiologic factors, such as birth decade. METHODS: The Utah Population Database was used to identify individuals with incident severe diverticulitis, defined as requiring an emergency department visit or hospitalization, between 1998 and 2018. This study measured the relationship between age and recurrent severe diverticulitis after adjusting for birth decade and other important variables, such as sex, urban/rural status, complicated diverticulitis, and body mass index using a Cox proportional hazards model. RESULTS: The cohort included 8606 individuals with a median age of 61 years at index diverticulitis diagnosis. After adjustment, among individuals born in the same birth decade, increasing age at diverticulitis onset was associated with an increased risk of recurrent diverticulitis (hazard ratio [HR] for 10 years, 1.8; 95% CI, 1.5-2.1). Among individuals with the same age of onset, those born in a more recent birth decade were also at greater risk of recurrent diverticulitis (HR, 1.9; 95% CI, 1.6-2.3). CONCLUSION: Among individuals with an index episode of severe diverticulitis, recurrence was associated with increasing age and more recent birth decade. Clinicians may wish to employ age-specific strategies when counseling patients regarding treatment options after a diverticulitis diagnosis.

Postsurgical opioid prescribing among veterans using community care for orthopedic surgery at non-VA hospitals compared to a VA hospital with a transitional pain service: a retrospective cohort study.

BACKGROUND: The USA provides medical services to its military veterans through Veterans Health Administration (VHA) medical centers. Passage of recent legislation has increased the number of veterans having VHA-paid orthopedic surgery at non-VHA facilities. METHODS: We conducted a retrospective cohort study among veterans who underwent orthopedic joint surgery paid for by the VHA either at the Salt Lake City VHA Medical Center (VAMC) or at non-VHA hospitals between January 2018 and December 2021. 562 patients were included in the study, of which 323 used a non-VHA hospital and 239 patients the VAMC. The number of opioid tablets prescribed at discharge, the total number prescribed by postdischarge day 90, and the number of patients still filling opioid prescriptions between 90 and 120 days after surgery were compared between groups. RESULTS: Veterans who underwent orthopedic surgery at a non-VHA hospital were prescribed more opioid tablets at discharge (median (IQR)); (40 (30-60) non-VHA vs 30 (20-47.5) VAMC, p<0.001) and in the first 90 days after surgery than patients who had surgery at the Salt Lake City VAMC (60 (40-120) vs 35 (20-60), p<0.001). Patients who had surgery at Salt Lake City VAMC were also significantly less likely to fill opioid prescriptions past 90 days after hospital discharge (OR (95% CI) 0.06 (0.01 to 0.48), p=0.007). CONCLUSION: These results suggest that veterans who have surgery at a veterans affairs hospital with a transitional pain service are at lower risk for larger opioid prescriptions both at discharge and within 90 days after surgery as well as persistent opioid use beyond 90 days after discharge than if they have surgery at a community hospital.

Accreditation Council for Graduate Medical Education Milestone Training Ratings and Surgeons' Early Outcomes.

Importance: National data on the development of competence during training have been reported using the Accreditation Council for Graduate Medical Education (ACGME) Milestones system. It is now possible to consider longitudinal analyses that link Milestone ratings during training to patient outcomes data of recent graduates. Objective: To evaluate the association of in-training ACGME Milestone ratings in a surgical specialty with subsequent complication rates following a commonly performed operation, endovascular aortic aneurysm repair (EVAR). Design, Setting, and Participants: This study of patient outcomes followed EVAR in the Vascular Quality Initiative (VQI) registry (4213 admissions from 208 hospitals treated by 327 surgeons). All surgeons included in this study graduated from ACGME-accredited training programs from 2015 through 2019 and had Milestone ratings 6 months prior to graduation. Data were analyzed from December 1, 2021, through September 15, 2023. Because Milestone ratings can vary with program, they were corrected for program effect using a deviation score from the program mean. Exposure: Milestone ratings assigned to individual trainees 6 months prior to graduation, based on judgments of surgical competence. Main Outcomes and Measures: Surgical complications following EVAR for patients treated by recent graduates during the index hospitalization, obtained using the nationwide Society for Vascular Surgery Patient Safety Organization's VQI registry, which includes 929 participating centers in 49 US states. Results: The study included outcomes for 4213 patients (mean [SD] age, 73.25 [8.74] years; 3379 male participants [80.2%]). Postoperative complications included 9.5% major (400 of 4213 cases) and 30.2% minor (1274 of 4213 cases) complications. After adjusting for patient risk factors and site of training, a significant association was identified between individual Milestone ratings of surgical trainees and major complications in early surgical practice in programs with lower mean Milestone ratings (odds ratio, 0.50; 95% CI; 0.27-0.95). Conclusions and Relevance: In this study, Milestone assessments of surgical trainees were associated with subsequent clinical outcomes in their early career. Although these findings represent one surgical specialty, they suggest Milestone ratings can be used in any specialty to identify trainees at risk for future adverse patient outcomes when applying the same theory and methodology. Milestones data should inform data-driven educational interventions and trainee remediation to optimize future patient outcomes.

Opioid tapering after surgery and its association with patient-reported outcomes and behavioral changes: a mixed-methods analysis.

INTRODUCTION: Opioid tapering after surgery is recommended among patients with chronic opioid use, but it is unclear how this process affects their quality of life. The objective of this study was to evaluate how opioid tapering following surgery was associated with patient-reported outcome measures related to pain control and behavioral changes that affect quality of life. METHODS: We conducted an explanatory sequential mixed-methods study at a VA Medical Center among patients with chronic opioid use who underwent a spectrum of orthopedic, vascular, thoracic, urology, otolaryngology, and general surgery procedures between 2018 and 2020. Patients were stratified based on the extent that opioid tapering was successful (complete, partial, and no-taper) by 90 days after surgery, followed by qualitative interviews of 10 patients in each taper group. Longitudinal patient-reported outcome measures related to pain intensity, interference, and catastrophizing were compared using Kruskal Wallis tests over the 90-day period after surgery. Qualitative interviews were conducted among patients in each taper group to identify themes associated with the impact of opioid tapering after surgery on quality of life. RESULTS: We identified 211 patients with chronic opioid use (92% male, median age 66 years) who underwent surgery during the time period, including 42 (20%) individuals with complete tapering, 48 (23%) patients with partial tapering, and 121 (57%) patients with no taper of opioids following surgery. Patients who did not taper were more likely to have a history of opioid use disorder (10%-partial, 2%-complete vs 17%-no taper, p<0.05) and be discharged on a higher median morphine equivalent daily dose (52-partial, 30-complete vs 60-no taper; p<0.05) than patients in the partial and complete taper groups. Pain interference (-7.2-partial taper and -9.8-complete taper vs -3.5-no taper) and pain catastrophizing (-21.4-partial taper and -16.5-complete taper vs -1.7-no taper) scores for partial and complete taper groups were significantly improved at 90 days relative to baseline when compared with patients in the no-taper group (p<0.05 for both comparisons), while pain intensity was similar between groups. Finally, patients achieving complete and partial opioid tapering were more likely to report improvements in activity, mood, thinking, and sleep following surgery as compared with patients who failed to taper. CONCLUSIONS: Partial and complete opioid tapering within 90 days after surgery among patients with chronic opioid use was associated with improved patient-reported measures of pain control as well as behaviors that impact a patient's quality of life.

Evaluating a health system-wide opioid disposal intervention distributing home-disposal bags.

OBJECTIVE: To evaluate a health system-wide intervention distributing free home-disposal bags to surgery patients prescribed opioids. DATA SOURCES AND STUDY SETTING: We collected patient surveys and electronic medical record data at an academic health system. STUDY DESIGN: We conducted a prospective observational study. The bags were primarily distributed at pharmacies, though pharmacists delivered bags to some patients. The primary outcome was disposal of leftover opioids (effectiveness). Secondary outcomes were patient willingness to dispose and factors associated with disposal (effectiveness), recalling receipt of the bag (reach), and recalling receipt of bags and disposal over time (maintenance). We used a modified Poisson regression to evaluate the relative risk of disposal. Inverse probability of treatment weighting, based on propensity scores, was used to account for differences between survey responders and non-responders and reduce nonresponse bias. DATA COLLECTION/EXTRACTION METHODS: From August 2020 to May 2021, we surveyed patients 2 weeks after discharge (allowing for home opioid use). Eligibility criteria were age ≥18, English being primary language, valid email address, hospitalization ≤30 days, discharge home, and an opioid prescription sent to a system pharmacy. PRINCIPAL FINDINGS: We identified 5134 patients with 2174 completing the survey (response rate 42.3%). Among respondents, 1375 (63.8%) recalled receiving the disposal bag. Among 1075 respondents with leftover opioids, 284 (26.4%) disposed, 552 (51.3%) planned to dispose, 79 (7.4%) did not plan to dispose, 69 (6.4%) had undecided, and 91 (8.5%) had not considered disposal. Recalling receipt of the bag (incidence rate ratio [IRR] 1.25, 95% confidence interval [CI] 1.13-1.37) was positively associated with disposal. Patients who used opioids in the last year were less likely to dispose (IRR 0.82, 95% CI 0.73-0.93). Disposal rates remained stable over the study period while recalling receipt of bags trended up. CONCLUSIONS: A pragmatic implementation of a disposal intervention resulted in lower disposal rates than prior trials.

Exogenous Testosterone Replacement Therapy Is Associated with Increased Risk for Vascular Graft Infections Among Hypogonadal Men.

BACKGROUND: Vascular graft infections (VGIs) are a major source of morbidity following vascular bypass surgery. Hypogonadal men may be at increased risk for impaired wound healing and infections, but it is unclear if testosterone replacement therapy (TRT) mitigates this risk. We designed this study to evaluate the relationship between hypogonadism and the use of testosterone replacement therapy (TRT) with subsequent risk for developing a VGI. METHODS: We performed a retrospective analysis of claims in the MarketScan database identifying men greater than 18 years of age who underwent placement of a prosthetic graft in the peripheral arterial circulation from January 2009 to December 2020. Patients were stratified based on diagnosis of hypogonadism and use of TRT within 180 days before surgery. The primary outcome was VGI and the need for surgical excision. The association between hypogonadism and TRT use on risk of VGI was analyzed using Kaplan-Meier plots and multivariate Cox proportional hazards models. RESULTS: We identified 18,312 men who underwent a prosthetic bypass graft procedure in the upper and lower extremity during the study period, of which 802 (5%) had diagnosis of hypogonadism. Among men with hypogonadism, 251 (31%) were receiving TRT. Patients on TRT were younger, more likely to be diabetic, and more likely develop a VGI during follow-up (14% vs. 8%; P < 0.001) that was in the lower extremity. At 5 years, freedom from VGI was significantly lower for hypogonadal men on TRT than patients not on TRT or without hypogonadism (Log rank P < 0.001). In Cox regression models adjusted for age, diabetes, obesity, smoking, corticosteroid use, and procedure type, hypogonadal men on TRT were at a significantly increased risk of graft infection (hazard ratio (HR):1.94, 95% confidence interval (CI):1.4-2.7; P < 0.001) compared to controls. CONCLUSIONS: This study demonstrates TRT among hypogonadal men is associated with an increased risk of prosthetic VGIs. Temporary cessation of TRT should be considered for men undergoing prosthetic graft implants, particularly those in the lower extremity.

Improving pain management and safe opioid use after surgery: A DMAIC-based quality intervention.

Background: Multimodal perioperative patient education and expectation-setting can reduce post-operative opioid use while maintaining pain control and satisfaction. As part of a quality-improvement project, we developed a standardized model for perioperative education built upon the American College of Surgeons (ACS) Safe and Effective Pain Control After Surgery (SEPCAS) brochure to improve perioperative education regarding opioid use and pain control. Material and methods: Our study was designed within the Define, Measure, Analyze, Improve, Control (DMAIC) quality-improvement framework. Patients were surveyed about the adequacy of their perioperative education regarding pain control and use of prescription opioid medication. After gathering baseline data, a multimodal educational intervention based on the SEPCAS brochure was implemented. Survey responses were then compared between groups. Results: Twenty-seven subjects were included from the pre-intervention period, and thirty-nine were included from the post-intervention period (n = 66). Those in the post-intervention period were more likely to report receiving the appropriate amount of education regarding recognizing the signs of opioid overdose and how to safely store and dispose of opioid medications. The majority of patients who received the SEPCAS brochure reported that it was useful in their post-operative recovery and that it should be given to every patient undergoing surgery. Conclusions: The ACS SEPCAS brochure is an effective tool for improving patient preparation to safely store and dispose of their opioid medication and recognize the signs of opioid overdose. The brochure was also well received by patients and perceived as an effective educational material.

Predictors of Arteriovenous Fistula Maturation among Patients with Severe Obesity.

BACKGROUND: There is an increasing prevalence of obesity among patients who develop end-stage renal disease and require dialysis. While referrals for arteriovenous fistulas (AVFs) among patients with class 2-3 obesity (i.e., body mass index [BMI] ≥ 35) are increasing, it is unclear what type of autogenous access is most likely to mature in this patient population. This study was designed to evaluate factors that impact maturation of AVF among patients with class ≥2 obesity. METHODS: We retrospectively reviewed AVFs created at a single center from 2016 to 2019 for patients who had undergone dialysis within the same healthcare system. Ultrasound studies were used to evaluate factors that defined functional maturation, including diameter, depth, and volume flow rates through the fistula. Logistic regression models were used to evaluate the risk-adjusted association between class ≥2 obesity and functional maturation. RESULTS: A total of 202 AVFs [radiocephalic (24%), brachiocephalic (43%), and transposed brachiobasilic (33%)] were created during the study period, of which 53 (26%) patients had a BMI >35. Functional maturation was significantly lower among patients with class ≥2 obesity undergoing brachiocephalic (58% obese versus 82% normal-overweight; P = 0.017), but not radiocephalic or brachiobasilic AVFs. This was primarily a result of excessive AVF depth in severely obese patients (9.6 ± 4.0 mm obese versus 6.0 ± 2.7 mm normal-overweight; P < 0.001), whereas there was no significant difference found in average volume flow or AVF diameter between groups. In risk-adjusted models, a BMI ≥35 was associated with a significantly lower likelihood of achieving AVF functional maturation (odds ratio: 0.38; 95% confidence interval: 0.18-0.78; P = 0.009) after controlling for age, sex, socioeconomic status, and fistula type. CONCLUSIONS: Patients with a BMI >35 are less likely to mature AVFs after creation. This principally affects brachiocephalic AVFs and occurs because of increased fistula depth as opposed to diameter or volume flow parameters. These data can help guide decision-making when planning AVF placement in severely obese patients.

Vascular Quality Initiative assessment of compliance with Society for Vascular Surgery clinical practice guidelines on the management of extracranial cerebrovascular disease.

OBJECTIVES: Compliance with Society for Vascular Surgery (SVS) clinical practice guidelines (CPGs) is associated with improved outcomes for the treatment of abdominal aortic aneurysm, but this has not been assessed for carotid artery disease. The Vascular Quality Initiative (VQI) registry was used to examine compliance with the SVS CPGs for the management of extracranial cerebrovascular disease and its impact on outcomes. METHODS: The 2021 SVS extracranial cerebrovascular disease CPGs were reviewed for evaluation by VQI data. Compliance rates by the center and provider were calculated, and the impact of compliance on outcomes was assessed using logistic regression with inverse probability-weighted risk adjustment for each CPG recommendation, allowing for clustering by the center. Our primary outcome was a composite end point of in-hospital stroke/death. As a secondary analysis, compliance with the 2021 SVS carotid implementation document recommendations and associated outcomes were also assessed. RESULTS: Of the 11 carotid CPG recommendations, 4 (36%) could be evaluated using VQI registry data. Median center-specific CPG compliance ranged from 38% to 95%, and median provider-specific compliance ranged from 36% to 100%. After adjustment, compliance with 2 of the recommendations was associated with lower rates of in-hospital stroke/death: first, the use of best medical therapy (antiplatelet and statin therapy) in low/standard surgical risk patients undergoing carotid endarterectomy for >70% asymptomatic stenosis (event rate in compliant vs noncompliant cases 0.59% vs 1.3%; adjusted odds ratio: 0.44, 95% confidence interval: 0.29-0.66); and second, carotid endarterectomy over transfemoral carotid artery stenting in low/standard surgical risk patients with >50% symptomatic stenosis (1.9% vs 3.4%; adjusted odds ratio: 0.55, 95% confidence interval: 0.43-0.71). Of the 132 implementation document recommendations, only 10 (7.6%) could be assessed using VQI data, with median center- and provider-specific compliance rates ranging from 67% to 100%. The impact of compliance on outcomes could only be assessed for 6 (4.5%) of these recommendations, and compliance with all 6 recommendations was associated with lower stroke/death. CONCLUSIONS: Few SVS recommendations could be assessed in the VQI because of incongruity between the recommendations and the VQI data variables collected. Although guideline compliance was extremely variable among VQI centers and providers, compliance with most of these recommendations was associated with improved outcomes after carotid revascularization. This finding confirms the value of guideline compliance, which should be encouraged for centers and providers. Optimization of VQI data to promote evaluation of guideline compliance and distribution of these findings to VQI centers and providers will help facilitate quality improvement efforts in the care of vascular patients.

The measurable impact of a diversity, equity, and inclusion editor on diversifying content, authorship, and peer review participation in the Journal of Vascular Surgery.

OBJECTIVE: Women and minorities remain under-represented in academic vascular surgery. This under-representation persists in the editorial peer review process which may contribute to publication bias. In 2020, the Journal of Vascular Surgery (JVS) addressed this by diversifying the editorial board and creating a new Editor of Diversity, Equity, and Inclusion (DEI). The impact of a DEI editor on modifying the output of JVS has not yet been examined. We sought to determine the measurable impact of a DEI editor on diversifying perspectives represented in the journal, and on contributing to changes in the presence of DEI subject matter across published journal content. METHODS: The authorship and content of published primary research articles, editorials, and special articles in JVS were examined from November 2019 through July 2022. Publications were examined for the year prior to initiation of the DEI Editor (pre), the year following (post), and from September 2021 to July 2022, accounting for the average 47-week time period from submission to publication in JVS (lag). Presence of DEI topics and women authorship were compared using χ2 tests. RESULTS: During the period examined, the number of editorials, guidelines, and other special articles dedicated to DEI topics in the vascular surgery workforce or patient population increased from 0 in the year prior to 4 (16.7%) in the 11-month lag period. The number of editorials, guidelines, and other special articles with women as first or senior authors nearly doubled (24% pre, 44.4% lag; P = .31). Invited commentaries and discussions were increasingly written by women as the study period progressed (18.7% pre, 25.9% post, 42.6% lag; P = .007). The number of primary research articles dedicated to DEI topics increased (5.6% pre, 3.3% post, 8.1% lag; P = .007). Primary research articles written on DEI topics were more likely to have women first or senior authors than non-DEI specific primary research articles (68.0% of all DEI vs 37.5% of a random sampling of non-DEI primary research articles; P < .001). The proportion of distinguished peer reviewers increased (from 2.8% in 2020 to 21.9% in 2021; P < .001). CONCLUSIONS: The addition of a DEI editor to JVS significantly impacted the diversification of topics, authorship of editorials, special articles, and invited commentaries, as well as peer review participation. Ongoing efforts are needed to diversify subject matter and perspective in the vascular surgery literature and decrease publication bias.

The Association Between Family History and Diverticulitis Recurrence: A Population-Based Study.

BACKGROUND: After initial nonoperative management of diverticulitis, individuals with a family history of diverticulitis may have increased risk of recurrent disease. OBJECTIVE: This study measured the association between family history and recurrent diverticulitis in a population-based cohort. DESIGN: This is a retrospective, population-based cohort study. SETTINGS: The cohort was identified from the Utah Population Database, a statewide resource linking hospital and genealogy records. PATIENTS: Individuals evaluated in an emergency department or hospitalized between 1998 and 2018 for nonoperatively managed diverticulitis were included. INTERVENTION: The primary predictor was a positive family history of diverticulitis, defined as diverticulitis in a first-, second-, or third-degree relative. MAIN OUTCOME MEASURES: This study measured the adjusted association between family history and the primary outcome of recurrent diverticulitis. A secondary outcome was elective surgery for diverticulitis. Additional analyses evaluated risk by degree of relation of the affected family member. RESULTS: The cohort included 4426 individuals followed for a median of 71 months. Median age was 64 years and 45% were male; 17% had complicated disease, 11% had recurrence, and 15% underwent elective surgery. After adjustment, individuals with a family history of diverticulitis had a similar risk of recurrence when compared to those without a family history (HR 1.0; 95% CI 0.8-1.2). However, individuals with a family history of diverticulitis were more likely to undergo elective surgery (HR 1.4; 95% CI 1.1-1.6). This effect was most pronounced in those with an affected first-degree family member (HR 1.7; 95% CI 1.4-2.2). LIMITATIONS: The use of state-specific data may limit generalizability. CONCLUSIONS: In this population-based analysis, individuals with a family history of diverticulitis were more likely to undergo elective surgery than those without a family history, despite similar risks of recurrence and complicated diverticulitis. Further work is necessary to understand the complex social, environmental, and genetic factors that influence diverticulitis treatment and outcomes.

High-intensity statin therapy reduces risk of amputation and reintervention among patients undergoing lower extremity bypass for chronic limb-threatening ischemia.

OBJECTIVE: Statins are considered standard-of-care medical therapy for patients undergoing lower extremity bypass (LEB) procedures for chronic limb-threatening ischemia (CLTI). It is unclear, however, whether up-titrating and maintaining patients on higher-intensity statin medications following LEB improves limb salvage outcomes. This study was designed to evaluate whether high-intensity statin therapy impacts the risk of amputation and reintervention following LEB for patients with CLTI. METHODS: The IBM MarketScan database was used to identify adult patients (18-99 years old) who underwent a LEB for CLTI between 2008 and 2017. Patients lacking insurance covering drug reimbursement or those who already had undergone amputation before time of bypass were excluded. Using pharmacy claims and national drug codes to define statin intensity, patients were stratified into three groups: high-intensity, low-intensity, and limited statin therapy. The association between intensity of statin therapy and need for reintervention and/or major amputation after LEB was analyzed using Kaplan-Meier curves and risk-adjusted Cox proportional hazard models. RESULTS: A total of 25,907 patients who underwent LEB for CLTI were identified, of which 6696 (26%) were maintained on high-dose statins, 9297 (36%) were on low-dose statins, and 9914 (38%) had inconsistent pharmacy claims for statin therapy after surgery. Patients on high-intensity statins were, on average, younger and more likely to be male with comorbid disease (diabetes, hypertension, hyperlipidemia, obesity, renal insufficiency, ischemic heart disease, cerebrovascular disease, and tobacco abuse) than patients on low-intensity statins or limited statin therapy (P < .001 for all comparisons). Following LEB, 6649 patients (25.6%) required a reintervention, and 2550 patients (9.8%) went on to have a major amputation during follow-up. Patients maintained on high-intensity statins after LEB had a significantly lower likelihood of requiring a reintervention (hazard ratio [HR], 0.48; 95% confidence interval [CI], 0.45-0.51; P < .001) or amputation (HR, 0.27; 95% CI, 0.24-0.30; P < .001) as compared with patients on limited statin therapy. Further, there was a dose-dependent effect for these outcomes relative to patients on low-intensity statins in risk-adjusted models, and it was independent of whether an autologous vein graft was used for the LEB. Finally, among patients who underwent a reintervention, high-dose statin therapy also significantly reduced the HR for subsequent amputation (HR, 0.21; 95% CI, 0.18-0.25; P < .001). CONCLUSIONS: Patients with CLTI on high-intensity therapy following LEB had a significantly lower risk of requiring subsequent reintervention and amputation when compared with patients on low-intensity statins or with limited statin use. These data suggest that patients with CLTI should be up-titrated and/or maintained on high-intensity statins following revascularization whenever possible.

Postsurgical Opioid Use Among Veterans Discharged to Skilled Care Facilities Compared to Veterans Discharged to Home After Orthopedic Surgery.

OBJECTIVES: To compare opioid use patterns among Veterans who were discharged to a skilled care facility vs home after orthopedic surgery at a VA hospital. DESIGN: We conducted a retrospective cohort study of Veterans who had orthopedic surgery at the Salt Lake City VA Medical Center (VAMC) between January 2018 and December 2021 and were followed by a transitional pain service. The principal outcome of interest was the time to stop opioid use after discharge from the hospital. SETTING AND PARTICIPANTS: Veterans not already on chronic opioid therapy who had orthopedic surgery at the Salt Lake City VAMC and were followed by a transitional pain service. METHODS: 448 patients were included in the study, of which 371 (83%) were discharged to home and 77 (17%) were discharged to a skilled care facility. Median days to opioid cessation were estimated using the Kaplan-Meier method with 95% CIs and compared with discharge disposition using a log-rank test. Time to opioid cessation following hospital discharge was compared to baseline characteristics using univariable and multivariable Cox proportional hazards models. RESULTS: Patients who were discharged to a skilled care facility used opioids for twice as long as those who were discharged home [median days (interquartile range)]: 22 (19, 26) vs 11 (10, 12), P < .001, respectively. When controlling for baseline characteristics in the multivariable analysis, discharge to a skilled care facility was significantly associated with continued opioid use at all time points [hazard ratio 0.63 (95% CI 0.44, 0.89), P = .009]. CONCLUSIONS AND IMPLICATIONS: Veterans discharged to a skilled care facility after orthopedic surgery used opioids for twice as long as those who were discharged to home. As postsurgical pain management guidelines change to focus on nonopioid pain modalities and opioid reduction, skilled care providers should adapt those strategies for their facilities.
