Infrapopliteal Endovascular Interventions for Claudication Are Associated with Poor Long-Term Outcomes in Medicare-Matched Registry Patients.

BACKGROUND: There are limited data supporting or opposing the use of infrapopliteal peripheral vascular interventions (PVI) for the treatment of claudication. OBJECTIVES: We aimed to evaluate the association of infrapopliteal PVI with long-term outcomes compared with isolated femoropopliteal PVI for the treatment of claudication. METHODS: We conducted a retrospective analysis of all patients in the Medicare-matched Vascular Quality Initiative database who underwent an index infrainguinal PVI for claudication from January 2004-December 2019 using Cox proportional hazards models. RESULTS: Of 14,261 patients (39.9% female; 85.6% age ≥65 years, 87.7% non-Hispanic white) who underwent an index infrainguinal PVI for claudication, 16.6% (N=2,369) received an infrapopliteal PVI. The median follow-up after index PVI was 3.7 years (IQR 2.1-6.1). Compared to patients who underwent isolated femoropopliteal PVI, patients receiving any infrapopliteal PVI had a higher 3-year cumulative incidence of conversion to CLTI (33.3% vs. 23.8%; P<0.001); repeat PVI (41.0% vs. 38.2%; P<0.01); and amputation (8.1% vs. 2.8%; P<0.001). After risk-adjustment, patients undergoing infrapopliteal PVI had a higher risk of conversion to CLTI (aHR 1.39, 95% CI, 1.25-1.53); repeat PVI (aHR 1.10, 95% CI, 1.01-1.19); and amputation (aHR 2.18, 95% CI, 1.77-2.67). Findings were consistent after adjusting for competing risk of death; in a 1:1 propensity-matched analysis; and in subgroup analyses stratified by TASC disease, diabetes, and end-stage kidney disease. CONCLUSIONS: Infrapopliteal PVI is associated with worse long-term outcomes than femoropopliteal PVI for claudication. These risks should be discussed with patients.

Practice patterns of peripheral vascular interventions for peripheral artery disease in the office-based laboratory setting versus outpatient hospital.

OBJECTIVE: Controversy exists regarding the value and limitations of different sites of service for peripheral artery disease treatment. We aimed to examine practice patterns associated with peripheral vascular interventions (PVIs) performed in the office-based laboratory (OBL) vs outpatient hospital site of service using a nationally representative database. METHODS: Using 100% Medicare fee-for-service claims data, we identified all patients undergoing PVI for claudication or chronic limb-threatening ischemia (CLTI) between January 2017 and December 2022. We evaluated the associations of patient and procedure characteristics with site of service using multivariable hierarchical logistic regression. We used multinomial regression models to estimate the relative risk ratios (RRRs) of site of service and intervention type (angioplasty, stent, or atherectomy) and intervention anatomic level (iliac, femoropopliteal, or tibial) after adjusting for baseline patient characteristics and clustering by physician. RESULTS: Of 848,526 PVI, 485,942 (57.3%) were performed in an OBL. OBL use increased significantly over time from 48.3% in 2017 to 65.5% in 2022 (P < .001). Patients treated in OBLs were more likely to be Black (adjusted odds ratio [aOR], 1.14; 95% confidence interval [CI], 1.11-1.18) or other non-White race (aOR, 1.13; 95% CI, 1.08-1.18), have fewer comorbidities, and undergo treatment for claudication vs CLTI (aOR, 1.30; 95% CI, 1.26-1.33) compared with patients treated in outpatient hospital settings. Physicians with majority practice (>50% procedures) in an OBL were more likely to practice in urban settings (aOR, 21.58; 95% CI, 9.31-50.02), specialize in radiology (aOR, 18.15; 95% CI, 8.92- 36.92), and have high-volume PVI practices (aOR, 2.15; 95% CI, 2.10-2.29). The median time from diagnosis to treatment was shorter in OBLs, particularly for patients with CLTI (29 vs 39 days; P < .001). The OBL setting was the strongest predictor of patients receiving an atherectomy alone (adjusted RRR [aRRR] 6.67; 95% CI, 6.59-6.76) or atherectomy + stent (aRRR, 10.84; 95% CI, 10.64-11.05), and these findings were consistent in subgroup analyses stratified by PVI indication. The OBL setting was also associated with higher risk of tibial interventions for both claudication (aRRR, 3.18; 95% CI, 3.11-3.25) and CLTI (aRRR, 1.89; 95% CI, 1.86-1.92). The average reimbursement (including professional and facility fees) was slightly higher for OBLs compared with the hospital ($8742/case vs $8459/case; P < .001). However, in a simulated cohort resetting the OBL's intervention type distribution to that of the hospital, OBLs were associated with a hypothetical cost savings of $221,219,803 overall and $2602 per case. CONCLUSIONS: The OBL site of service was associated with greater access to care for non-White patients and a shorter time from diagnosis to treatment, but more frequently performed high-cost interventions compared with the outpatient hospital setting. The benefit to patients from improved access to peripheral artery disease care in OBL settings must be balanced with the potential limitations of receiving differential care.

The impact of a virtual mind-body program on symptoms of depression and anxiety among international English-speaking adults with neurofibromatosis.

The neurofibromatoses (NFs) are a set of incurable genetic disorders that predispose individuals to nervous system tumors. Although many patients experience anxiety and depression, there is little research on psychosocial interventions in this population. The present study examined the effects of a mind-body intervention on depression and anxiety in adults with NF. This is a secondary analysis of the Relaxation Response Resiliency Program for NF (3RP-NF), an 8-week virtual group intervention that teaches mind-body skills (e.g., relaxation, mindfulness) to improve quality of life. Participants were randomized to 3RP-NF or the Health Enhancement Program for NF (HEP-NF) consisting of health informational sessions and discussion. We evaluated depression (PHQ-9) and anxiety (GAD-7) at posttreatment, 6 months, and 12 months. Both groups improved in depression and anxiety between baseline and posttest, 6 months, and 12 months. The 3RP-NF group showed greater improvements in depression scores from baseline to 6 months compared with HEP-NF and with lower rates of clinically significant depressive symptoms. There were no between-group differences for anxiety. Both interventions reduced distress and anxiety symptoms for individuals with NF. The 3RP-NF group may be better at sustaining these improvements. Given the rare nature of NF, group connection may facilitate reduced distress.

Associations of Cardiac Biomarkers With Peripheral Artery Disease and Peripheral Neuropathy in US Adults Without Prevalent Cardiovascular Disease.

BACKGROUND: NT-proBNP (N-terminal pro-B-type natriuretic peptide), high-sensitivity cardiac troponin T (hs-troponin T), and high-sensitivity cardiac troponin I (hs-troponin I) are increasingly being recommended for risk stratification for a variety of cardiovascular outcomes. The aims of our study were to establish the prevalence and associations of elevated NT-proBNP, hs-troponin T, and hs-troponin I with lower extremity disease, including peripheral artery disease (PAD) and peripheral neuropathy (PN), in the US general adult population without known cardiovascular disease. We also assessed whether the combination of PAD or PN and elevated cardiac biomarkers was associated with an increased risk of all-cause and cardiovascular mortality. METHODS: We conducted a cross-sectional analysis of the associations of NT-proBNP, hs-troponin T, and hs-troponin I with PAD (based on ankle-brachial index <0.90) and PN (diagnosed by monofilament testing) in adult participants aged ≥40 years of age without prevalent cardiovascular disease in NHANES (National Health and Nutrition Examination Survey) 1999 to 2004. We calculated the prevalence of elevated cardiac biomarkers among adults with PAD and PN and used multivariable logistic regression to assess the associations of each cardiac biomarker, modeled using clinical cut points, with PAD and PN separately. We used multivariable Cox proportional hazards models to assess the adjusted associations of cross categories of clinical categories of each cardiac biomarker and PAD or PN with all-cause and cardiovascular mortality. RESULTS: In US adults aged ≥40 years, the prevalence (±SE) of PAD was 4.1±0.2% and the prevalence of PN was 12.0±0.5%. The prevalence of elevated NT-proBNP (≥125 ng/L), hs-troponin T (≥6 ng/L), and hs-troponin I (≥6 ng/L for men and ≥4 ng/L for women) was 54.0±3.4%, 73.9±3.5%, and 32.3±3.7%, respectively, among adults with PAD and 32.9±1.9%, 72.8±2.0%, and 22.7±1.9%, respectively, among adults with PN. There was a strong, graded association of higher clinical categories of NT-proBNP with PAD after adjusting for cardiovascular risk factors. Clinical categories of elevated hs-troponin T and hs-troponin I were strongly associated with PN in adjusted models. After a maximum follow-up of 21 years, elevated NT-proBNP, hs-troponin T, and hs-troponin I were each associated with all-cause and cardiovascular mortality, with higher risks of death observed among adults with elevated cardiac biomarkers plus PAD or PN compared with elevated biomarkers alone. CONCLUSIONS: Our study establishes a high burden of subclinical cardiovascular disease defined by cardiac biomarkers in people with PAD or PN. Cardiac biomarkers provided prognostic information for mortality within and across PAD and PN status, supporting the use of these biomarkers for risk stratification among adults without prevalent cardiovascular disease.

Risks and Benefits of the Proposed Amputation Reduction and Compassion Act for Disadvantaged Patients.

Racial, ethnic, and socioeconomic disparities in the major risk factors for vascular disease and access to vascular specialist care are well-documented.1-3 The higher incidence of diabetes, peripheral artery disease (PAD), and related nontraumatic lower extremity amputation among racial and ethnic minority groups, those of low socioeconomic status, and those with poor access to care based on geography (together, referred to below as disadvantaged groups) are particularly pervasive.1,4-9 Practitioners of vascular surgery and endovascular therapy are uniquely positioned to address health inequities in lower extremity screening, medical management, intervention, and limb preservation among the population of adults at the highest risk for limb loss.

The impact of a virtual mind-body program on resilience factors among international English-speaking adults with neurofibromatoses: secondary analysis of a randomized clinical trial.

PURPOSE: To test the effects of the Relaxation Response Resiliency Program - Neurofibromatosis (3RP-NF), a mind-body resilience program for people with NF, on resilience factors from baseline to post-treatment and 6- and 12-month follow-up. METHODS: This is a secondary analysis of a fully powered randomized clinical trial (RCT) of 3RP-NF and health education control (HEP-NF). We recruited adults with NF1, NF2, or schwannomatosis who reported stress or difficulty coping with NF symptoms. Both conditions received 8 weekly 90-minute group sessions; 3RP-NF focused on building resilience skills. We measured resilience factors via the Measure of Current Status-A (adaptive coping), Cognitive and Affective Mindfulness Scale-Revised (mindfulness), Gratitude Questionnaire-6 (gratitude), Life Orientation Test Optimism Scale (optimism), and Medical Outcomes Study Social Support Survey (perceived social support) at baseline, post-intervention, and 6- and 12-month follow-up. We used linear mixed models with completely unstructured covariance across up to four repeated measurements (baseline, post-treatment, and 6- and 12-month follow-up) to investigate treatment effects on resilience factors. RESULTS: We enrolled 228 individuals (Mage=42.7, SD = 14.6; 74.5% female; 87.7% White; 72.8% NF1, 14.0% NF2, 13.2% schwannomatosis). Within groups, both 3RP-NF and HEP-NF showed statistically significant improvements in all outcomes across timepoints. 3RP-NF showed significantly greater improvement in adaptive coping compared to HEP-NF from baseline to post-intervention and baseline to 6 months (Mdifference= 0.29; 95% CI 0.13-0.46; p < 0.001; Mdifference= 0.25; 95% CI 0.07-0.33; p = 0.005); there were no other between-group differences amongst the remaining resilience factors. CONCLUSION: 3RP-NF showed promise in sustainably improving coping abilities amongst people with NF. TRIAL REGISTRATION INFORMATION: ClinicalTrials.gov Identifier: NCT03406208.

A 10-Year Analysis of Representation of Women in Patent Applications and NIH Funding in Vascular Surgery.

BACKGROUND: There has been an increasing focus on gender disparities in the medical field and in the field of vascular surgery specifically. We aimed to characterize gender representation in vascular surgery innovation over the past 10 years, using metrics of patents and National Institutes of Health (NIH) support. METHODS: We performed a retrospective review of all vascular-related patent filings (Google Scholar) and NIH-funded grants (NIH RePORTER) over a 10-year period (January 1st, 2012, to December 31st, 2021). Gender-API (Application Programming Interface) was used to identify the gender of the inventors, with manual confirmation of a 10% random sample. Gender representation for patent inventors and grant principal investigators (PIs) were compared using Chi-squared and Student's t-tests as appropriate. Yearly temporal changes in representation were analyzed using Wilcoxon signed-rank tests and linear regression analyses. RESULTS: We identified 2,992 unique vascular device patents with 6,093 associated inventors over 10 years. Women were underrepresented in patent authorship overall (11.5%), and were least likely to be listed as first inventor (8.9%) and most commonly fourth and fifth inventors (15.5% and 14.1%, respectively) compared to men. There was no significant change in representation of women inventors over time (-0.2% females per year, 95% confidence interval (CI) -0.54 to 0.10). We identified 1736 total unique NIH grants, with 23.8% of funded projects having women PIs. There was an increase in the proportion of women PIs over time (+1.31% per year, 95% CI 0.784 to 1.855; P < 0.001). Projects with women PIs received mean total awards that were significantly lower than projects with men PIs ($350,485 ± $220,072 vs. $451,493 ± $411,040; P < 0.001), but the overall ratio of funding:women investigators improved over time (+$11,531 per year, 95% CI $6,167 to $16,895; P = 0.0011). CONCLUSIONS: While we have made strides in increasing the number of women in the surgical research space, there is still room for improvement in funding parity. In addition, we found substantial and persistent room for improvement in representation of women in surgical innovation. As we enter a new frontier of surgery hallmarked by equalizing gender representation, these data should serve as a call-to-action for initiative aimed at rebuilding the foundation of surgical innovations upon equal gender representation.

The Role of Safety Behaviors in the Relationship between Social Anxiety and Marijuana Use Problems.

Background: Social anxiety has been associated with higher levels of and more problematic marijuana use. Research suggests that safety behaviors may play a role in the development and maintenance of marijuana problems. However, the safety behaviors that are most commonly associated with social anxiety have not been investigated, nor has the potential moderating role of gender on this relationship. Method: A diverse sample of regular marijuana users (N = 279) completed measures of social anxiety, safety behaviors related to social situations, and marijuana use problems. Results: Social anxiety and safety behavior use were both positively correlated with marijuana use problems. These relationships were stronger in men than in women. Among men only, tendencies to use safety behaviors to cope with social situations accounted for the relationship between social anxiety symptoms and marijuana-related problems. Discussion: The avoidant coping style that characterizes safety behaviors in social anxiety may also underlie problematic patterns of marijuana use, particularly for men. The present study is the first to report an association between safety behaviors in social situations and marijuana use problems and suggests the importance of examining the effect of reducing safety behaviors in social situations, in regular marijuana users with comorbid social anxiety.

Development of the Response to Fearful Situations Scale.

BACKGROUND: Most measures of anxious avoidance are limited to disorder-specific mechanisms and ignore the measurement of courage/approach responding in confronting fearful situations. AIMS: The purpose of the present study was to construct and validate a self-report assessment of the tendency towards avoidant or approach responding in fearful situations, the Response to Fearful Situations Scale (RFSS). METHOD AND RESULTS: In Study 1 (n = 241), exploratory factor analysis resulted in two factors, avoidance and approach. Study 2 (n = 423) replicated the two-factor structure and established test-re-test reliability. In Study 3 (n = 44), the RFSS demonstrated predictive validity on a behavioural avoidance task. In Studies 4 (n = 253) and 5 (n = 256), the RFSS was associated with clinical symptoms above existing measures of avoidance. DISCUSSION: These results validate the use of the RFSS as a transdiagnostic measure of avoidance and approach.

"Not just right" experiences account for unique variance in eating pathology.

"Not just right" experiences (NJREs) are uncomfortable sensations of incompleteness linked to obsessive-compulsive disorder; however, NJREs may be transdiagnostic and play a role in eating pathology. The current study examined relations between NJREs and eating pathology in undergraduate students. Participants (n = 248) completed self-report and behavioral assessments. Controlling for obsessive-compulsive symptoms, negative affect, and perfectionism, NJRE frequency was associated with greater drive for thinness, body dissatisfaction, and bulimic symptoms. Discomfort in response to a visual in vivo NJRE task was positively associated with drive for thinness and body dissatisfaction. The present study provides initial evidence for NJREs in eating pathology. Theoretical implications are discussed.

Grit in patients with substance use disorders.

BACKGROUND AND OBJECTIVES: Grit is an emerging concept in positive psychology, defined as the ability to be persistent and focused in pursuit of long-term goals. This concept has received a great deal of interest recently because of its robust ability to predict success and well-being across a wide variety of domains. The study aim was to examine the clinical relevance of the construct of grit among patients with substance use disorders. METHODS: Inpatients on a detoxification unit were enrolled from September 2013 to August 2015 (N = 673). Psychometric properties of the Short Grit Scale (Grit-S) were reported. We then examined sociodemographic and clinical variables that might be associated with grit in this population. RESULTS: In this sample of patients with substance use disorders, the total Grit-S demonstrated strong psychometric properties. Grit-S scores were higher among older patients and those who were employed; scores were lower among those never married, diagnosed with a co-occurring psychiatric disorder, or who had used heroin during the past month, according to bivariate analyses. Grit-S scores remained associated with age, employment, and presence of a co-occurring psychiatric disorder in adjusted analysis. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: This study provides initial support for the utility of the Grit-S among those with substance use disorders; this novel measure has not been previously reported in clinical populations. Research examining grit prospectively is needed to determine whether the links between grit and outcomes observed in other populations apply to patients with substance use disorders.

Identifying patients with problematic drug use in the emergency department: results of a multisite study.

STUDY OBJECTIVE: Drug-related emergency department (ED) visits have steadily increased, with substance users relying heavily on the ED for medical care. The present study aims to identify clinical correlates of problematic drug use that would facilitate identification of ED patients in need of substance use treatment. METHODS: Using previously validated tests, 15,224 adult ED patients across 6 academic institutions were prescreened for drug use as part of a large randomized prospective trial. Data for 3,240 participants who reported drug use in the past 30 days were included. Self-reported variables related to demographics, substance use, and ED visit were examined to determine their correlative value for problematic drug use. RESULTS: Of the 3,240 patients, 2,084 (64.3%) met criteria for problematic drug use (Drug Abuse Screening Test score ≥ 3). Age greater than or equal to 30 years, tobacco smoking, daily or binge alcohol drinking, daily drug use, primary noncannabis drug use, resource-intense ED triage level, and perceived drug-relatedness of ED visit were highly correlated with problematic drug use. Among primary cannabis users, correlates of problematic drug use were age younger than 30 years, tobacco smoking, binge drinking, daily drug use, and perceived relatedness of the ED visit to drug use. CONCLUSION: Clinical correlates of drug use problems may assist the identification of ED patients who would benefit from comprehensive screening, intervention, and referral to treatment. A clinical decision rule is proposed. The correlation between problematic drug use and resource-intense ED triage levels suggests that ED-based efforts to reduce the unmet need for substance use treatment may help decrease overall health care costs.

Pediatric Trauma Recidivism: A Statewide Risk Factor Analysis of the Maryland Health Services Cost Review Commission (HSCRC).

BACKGROUND: National estimates suggest pediatric trauma recidivism is uncommon but are limited by short follow up and narrow ascertainment. We aimed to quantify the long-term frequency of trauma recidivism in a statewide pediatric population and identify risk factors for re-injury. METHODS: The Maryland Health Services Cost Review Commission Dataset was queried for 0-19-year-old patients with emergency department or inpatient encounters for traumatic injuries between 2013 and 2019. We measured trauma recidivism by identifying patients with any subsequent presentation for a new traumatic injury. Univariate and multivariable regressions were used to estimate associations of patient and injury characteristics with any recidivism and inpatient recidivism. RESULTS: Of 574,472 patients with at least one injury encounter, 29.6% experienced trauma recidivism. Age ≤2 years, public insurance, and self-inflicted injuries were associated with recidivism regardless of index treatment setting. Of those with index emergency department presentations 0.06% represented with an injury requiring inpatient admission; unique risk factors for ED-to-inpatient recidivism were age >10 years (aOR 1.61), cyclist (aOR 1.31) or burn (aOR 1.39) mechanisms, child abuse (aOR 1.27), and assault (aOR 1.43). Among patients with at least one inpatient encounter, 6.3% experienced another inpatient trauma admission, 3.4% of which were fatal. Unique risk factors for inpatient-to-inpatient recidivism were firearm (aOR 2.48) and motor vehicle/transportation (aOR 1.62) mechanisms of injury (all p < 0.05). CONCLUSIONS: Pediatric trauma recidivism is more common and morbid than previously estimated, and risk factors for repeat injury differ by treatment setting. Demographic and injury characteristics may help develop and target setting-specific interventions. LEVEL OF EVIDENCE: III (Retrospective Comparative Study).

Improving multimodal physical function in adults with heterogeneous chronic pain; Protocol for a multisite feasibility RCT.

BACKGROUND: Chronic pain is associated with substantial impairment in physical function, which has been identified as a top concern among persons with pain. GetActive-Fitbit, a mind-body activity program, is feasible, acceptable, and associated with improvement in physical function among primarily White, sedentary individuals with pain. In preparation for a multisite efficacy trial, we must examine feasibility across multiple sites with diverse patient populations. Here we describe the protocol of a multisite, feasibility RCT comparing GetActive-Fitbit with a time- and attention-matched educational comparison (Healthy Living for Pain). We aim to 1) test multisite fidelity of clinician training; 2) evaluate multisite feasibility benchmarks, including recruitment of chronic pain patients taking <5000 steps/day and racial and ethnic minorities; and 3) optimize fidelity and study protocol in preparation for a future multisite efficacy trial. METHODS: Clinician training fidelity was assessed via roleplays and mock group sessions. Feasibility (i.e., recruitment, acceptability, credibility, adherence, satisfaction), multimodal physical function (e.g., self-report, 6-Minute Walk Test, step-count), and other psychosocial outcomes are assessed at baseline, posttest, and 6 months. Protocol optimization will be assessed using exit interviews and cross-site meetings. RESULTS: The trial is ongoing. Clinician training is complete. 87 participants have been recruited. 54 completed baseline assessments and randomization, 44 are mid-intervention, and 9 have completed the intervention and posttest. CONCLUSIONS: This study addresses the critical need for feasible, acceptable mind-body-activity interventions for chronic pain that follow evidence-based guidelines and improve all aspects of physical function across diverse populations. Results will inform a future fully-powered multisite efficacy trial. CLINICAL TRIAL REGISTRATION: NCT05700383.

Trends and Factors Associated With Peripheral Vascular Interventions for the Treatment of Claudication From 2011 to 2022: A National Medicare Cohort Study.

BACKGROUND: Previous cross-sectional studies have identified wide practice pattern variations in the use of peripheral vascular interventions (PVIs) for the treatment of claudication. However, there are limited data on longitudinal practice patterns. We aimed to describe the temporal trends and charges associated with PVI use for claudication over the past 12 years in the United States. METHODS AND RESULTS: We conducted a retrospective analysis using 100% Medicare fee-for-service claims data to identify all patients who underwent a PVI for claudication between January 2011 and December 2022. We evaluated the trends in utilization and Medicare-allowed charges of PVI according to anatomic level, procedure type, and intervention settings using generalized linear models. Multinomial logistic regressions were used to evaluate factors associated with different levels and types of PVI. We identified 599 197 PVIs performed for claudication. The proportional use of tibial PVI increased 1.0% per year, and atherectomy increased by 1.6% per year over the study period. The proportion of PVIs performed in ambulatory surgical centers/office-based laboratories grew at 4% per year from 12.4% in 2011 to 55.7% in 2022. Total Medicare-allowed charges increased by $11 980 035 USD/year. Multinomial logistic regression identified significant associations between race and ethnicity and treatment setting with use of both atherectomy and tibial PVI. CONCLUSIONS: The use of tibial PVI and atherectomy for the treatment of claudication has increased dramatically in in ambulatory surgical center/office-based laboratory settings, non-White patients, and resulting in a significant increase in health care charges. There is a critical need to improve the delivery of value-based care for the treatment of claudication.

Bridging the gap: Utilizing insights from exposure therapy in the innovation of chronic musculoskeletal pain treatment.

For some time, the gold standard treatment for anxiety disorders has been exposure therapy, defined as the repeated approach of anxiety-inducing situations, memories, or physiological sensations. Existing treatments to target fear and avoidance of pain can be augmented by innovations from exposure research in the anxiety disorders, including greater emphasis on safety learning, the utilization of imaginal exposure to catastrophic fears, and exposure to contrasting emotions. Given that treatments to target core, maintaining mechanisms of anxiety, including imaginal exposures, can be administered as self-directed treatments without therapist involvement, they represent important avenues for ensuring the millions of people with chronic musculosketal pain can gain access to psychosocial treatment and reduce the interference of pain in their lives.

Multidisciplinary approach to decreasing major amputation, improving outcomes, and mitigating disparities in diabetic foot and vascular disease.

Major nontraumatic lower extremity amputation (LEA) is a morbid complication of longstanding or poorly controlled diabetes and/or end-stage peripheral artery disease. Incidence of major LEAs consistently declined during the 1990s and 2000s, but rates have plateaued or increased in many regions during the past decade. Marked racial, ethnic, socioeconomic, and geographic disparities in risk of LEA persist and are related to inequalities in access to care and differential rates of attempted limb preservation. Multidisciplinary diabetic foot care (MDFC) is increasingly recognized as a necessary model for optimal management of patients with diabetic foot and vascular disease. This article reviews the role of MDFC in reducing major LEAs and the specific ways in which MDFC can mitigate disparities in care delivery and limb preservation outcomes. Access to MDFC among vulnerable populations remains a significant barrier to systematic reduction in major LEAs.

Disparities in limb preservation and associated socioeconomic burden among patients with diabetes and/or peripheral artery disease in the United States.

Racial, ethnic, socioeconomic, and geographic disparities in limb preservation and nontraumatic lower extremity amputation (LEA) are consistently demonstrated in populations with diabetes and peripheral artery disease (PAD). Higher rates of major LEA in disadvantaged groups are associated with increased health care utilization and higher costs of care. Functional decline that often follows major LEA confers substantial risk of disability and premature mortality, and the burden of these outcomes is more prevalent in racial and ethnic minority groups, people with low socioeconomic status, and people in geographic regions where limited resources or distance from specialty care are barriers to access. We present a narrative review of the existing literature on estimated costs of diabetic foot disease and PAD, inequalities in care that contribute to excess costs, and disparities in outcomes that lead to a disproportionate burden of diabetes- and PAD-related LEA on systematically disadvantaged populations.

Etiology, Epidemiology, and Disparities in the Burden of Diabetic Foot Ulcers.

Diabetic foot ulcers (DFU) are a major source of preventable morbidity in adults with diabetes. Consequences of foot ulcers include decline in functional status, infection, hospitalization, lower-extremity amputation, and death. The lifetime risk of foot ulcer is 19% to 34%, and this number is rising with increased longevity and medical complexity of people with diabetes. Morbidity following incident ulceration is high, with recurrence rates of 65% at 3-5 years, lifetime lower-extremity amputation incidence of 20%, and 5-year mortality of 50-70%. New data suggest overall amputation incidence has increased by as much as 50% in some regions over the past several years after a long period of decline, especially in young and racial and ethnic minority populations. DFU are a common and highly morbid complication of diabetes. The pathway to ulceration, involving loss of sensation, ischemia, and minor trauma, is well established. Amputation and mortality after DFU represent late-stage complications and are strongly linked to poor diabetes management. Current efforts to improve care of patients with DFU have not resulted in consistently lower amputation rates, with evidence of widening disparities and implications for equity in diabetes care. Prevention and early detection of DFU through guideline-directed multidisciplinary care is critical to decrease the morbidity and disparities associated with DFU. This review describes the epidemiology, presentation, and sequelae of DFU, summarizes current evidence-based recommendations for screening and prevention, and highlights disparities in care and outcomes.
