Over the past decade, multidisciplinary “toe and flow” programs have gained great popularity, with proven benefits in limb salvage. Many vascular surgeons have incorporated podiatrists into their practices. The viability of this practice model requires close partnership, hospital support, and financial sustainability. We intend to examine the economic values of podiatrists in a busy safety-net hospital in the Southwest United States.
An administrative database that captured monthly operating room (OR) cases, clinic encounters, in-patient volume, and total work relative value units (wRVUs) in an established limb salvage program in a tertiary referral center were examined. The practice has a diverse patient population with >30% of minority patients. During a period of 3years, there was a significant change in the number of podiatrists (from 1 to 4) within the program, whereas the clinical full-time employees for vascular surgeons remained relatively stable.
The limb salvage program experienced >100% of growth in total OR volumes, clinic encounters, and total wRVUs over a period of 4years. A total of 35,591 patients were evaluated in a multidisciplinary limb salvage clinic, and 5535 procedures were performed. The initial growth of clinic volume and operative volume (P< .01) were attributed by the addition of vascular surgeons in year one. However, recruitment of podiatrists to the program significantly increased clinic and OR volume by an additional 60% and >40%, respectively (P< .01) in the past 3years. With equal number of surgeons, podiatry contributed 40% of total wRVUs generated by the entire program in 2019. Despite the fact that that most of the foot and ankle procedures that were regularly performed by vascular surgeons were shifted to the podiatrists, vascular surgeons continued to experience an incremental increase in operative volume and >10% of increase in wRVUs.
This study shows that the value of close collaboration between podiatry and vascular in a limb salvage program extends beyond a patient's clinical outcome. A financial advantage of including podiatrists in a vascular surgery practice is clearly demonstrated.
During a period of 5years, there was a significant fluctuation in the composition of the Southern Arizona Limb Salvage Alliance (SALSA), an established integrated “toe and flow” team. Although there was an incremental increase in the number of vascular surgeons from 2 in 2015 and 2016 to a full complement of 4 in 2018, the clinical full-time employee (cFTE) remained relatively stable. The podiatry cFTE, however, changed from 1 in 2017 to 4 in 2019, and 50% of podiatric surgeons have advanced
A total of 35,591 patient encounters in the SALSA clinic and 5535 operative procedures were performed during the period of 5years. The entire department experienced >100% of growth in clinic visits, operative cases, and total wRVU by 2019 compared with 2015 (P< .01; Table). With the equal number of podiatric and vascular surgeons in 2019, podiatry contributes to 40% of total OR cases andin-patient encounters, as well as 70% of clinic encounters.
The initial significant growth of clinic volume
Podiatry plays a central role in DFU prevention and limb preservation.7 Many systematic reviews have shown that multidisciplinary teams have lower major amputation rates10, 11, 12 as well as the clinical benefits of a podiatrist in a diabetic limb salvage team.13, 14, 15, 16 In our SALSA “toe and flow” model, podiatric surgeons are recruited into a vascular surgery division. We have previously showed that this alliance has improved clinical outcomes and decreased lower extremity amputations.17
In conclusion, DFUs and PAD are complex pathologies that require a team approach to achieve optimal outcomes. This study shows that the value of close collaboration between podiatry and vascular in a limb salvage program extends beyond a patient's clinical outcome and that a “toe and flow” model is financially viable for a hospital system. This study contributes to the paucity of literature that helps to justify podiatric recruitment in a health care system.

Research articleNon–guideline-compliant endovascular abdominal aortic aneurysm repair in women is associated with increased mortality and reintervention compared with men
Journal of Vascular Surgery, Volume 75, Issue 1, 2022, pp. 118-125.e1
Sex-based disparities in surgical outcomes have emerged as an important focus in contemporary healthcare delivery. Likewise, the appropriate usage of endovascular abdominal aortic aneurysm repair (EVAR) in the United States remains a subject of ongoing controversy, with a significant number of U.S. EVARs failing to adhere to the Society for Vascular Surgery (SVS) clinical practice guideline (CPG) diameter thresholds. The purpose of the present study was to determine the effect of sex among patients undergoing EVAR that was not compliant with the SVS CPGs.
All elective EVAR procedures for abdominal aortic aneurysms without a concomitant iliac aneurysm (≥3.0cm) in the SVS Vascular Quality Initiative were analyzed (2015-2019; n= 25,112). SVS CPG noncompliant repairs were defined as a size of<5.5cm for men and<5.0cm for women. The primary endpoint was 30-day mortality. The secondary endpoints were all-cause mortality, complications, and reintervention. Logistic regression was performed to control for surgeon- and patient-level factors. Freedom from the endpoints was determined using the Kaplan-Meier method.
Noncompliant EVAR was performed in 9675 patients (38.5%). Although men were significantly more likely to undergo such procedures (90% vs 10%; odds ratio [OR], 3.1; 95% confidence interval [CI], 2.9-3.4; P< .0001), the 30-day mortality was greater for the women than the men (1.8% vs 0.5%; P= .0003). Women also experienced significantly higher rates of multiple complications, including postoperative myocardial infarction (1% vs 0.3%; P= .006), respiratory failure (1.4% vs 0.6%; P= .01), intestinal ischemia (0.7% vs 0.2%; P= .003), access vessel hematoma (3% vs 1.2%; P= .0006), and iliac access vessel injury (2.4% vs 0.8%; P< .0001). Additionally, women experienced increased overall 1-year reintervention rates (11.5% vs 5.8%; P< .0001). In the adjusted analysis, 30-day mortality and any in-hospital complication risk remained significantly greater for the women (30-day death: OR, 3.1; 95% CI, 1.6-5.8; P= .0005; in-hospital complication: OR, 1.9; 95% CI, 1.4-2.6; P< .0001). Women also experienced increased reintervention rates over time compared with men (OR, 1.5; 95% CI, 1.1-2.2; P= .02).
Although men were more likely to undergo non–CPG compliant EVAR, women experienced increased short-term morbidity and 30-day mortality and higher rates of reintervention when undergoing non–CPG compliant EVAR. These unanticipated findings necessitate increased scrutiny of current U.S. sex-based EVAR practice and should caution against the use of non–CPG compliant EVAR for women.(Video) Embracing a Limb Salvage Team

Research articleA statewide quality improvement collaborative significantly improves quality metric adherence and physician engagement in vascular surgery
Journal of Vascular Surgery, Volume 75, Issue 1, 2022, pp. 301-307
Quality improvement national registries provide structured, clinically relevant outcome and process-of-care data to practitioners—with regional meetings to disseminate best practices. However, whether a quality improvement collaborative affects processes of care is less clear. We examined the effects of a statewide hospital collaborative on the adherence rates to best practice guidelines in vascular surgery.
A large statewide retrospective quality improvement database was reviewed for 2013 to 2019. Hospitals participating in the quality improvement collaborative were required to submit adherence and outcomes data and meet semiannually. They received an incentive through a pay for participation model. The aggregate adherence rates among all hospitals were calculated and compared.
A total of 39 hospitals participated in the collaborative, with attendance of surgeon champions at face-to-face meetings of >85%. Statewide, the hospital systems improved every year of participation in the collaborative across most “best practice” domains, including adherence to preoperative skin preparation recommendations (odds ratio [OR], 1.83; 95% confidence interval [CI], 1.76-1.79; P< .001), intraoperative antibiotic redosing (OR, 1.09; 95% CI, 1.02-1.17; P= .018), statin use at discharge for appropriate patients (OR, 1.18; 95% CI, 1.16-1.2; P< .001), and reducing transfusions for asymptomatic patients with hemoglobin >8mg/dL (OR, 0.66; 95% CI, 0.66-0.66; P< .001). The use of antiplatelet therapy at discharge remained high and did not change significantly during the study period. Teaching hospital and urban or rural status did not affect adherence. The adherence rates exceeded the professional society mean rates for guideline adherence.
The use of a statewide hospital collaborative with incentivized semiannual meetings resulted in significant improvements in adherence to “best practice” guidelines across a large, heterogeneous group of hospitals.
