Defining the 90-day cost structure of lower extremity revascularization for alternative payment model assessment.

BACKGROUND: The U.S. healthcare system is undergoing a broad transformation from the traditional fee-for-service model to value-based payments. The changes introduced by the Medicare Quality Payment Program, including the establishment of Alternative Payment Models, ensure that the practice of vascular surgery is likely to face significant reimbursement changes as payments transition to favor these models. The Society for Vascular Surgery Alternative Payment Model taskforce was formed to explore the opportunities to develop a physician-focused payment model that will allow vascular surgeons to continue to deliver the complex care required for peripheral arterial disease (PAD). METHODS: A financial analysis was performed based on Medicare beneficiaries who had undergone qualifying index procedures during fiscal year 2016 through the third quarter of 2017. Index procedures were defined using a list of Healthcare Common Procedural Coding (HCPC) procedure codes that represent open and endovascular PAD interventions. Inpatient procedures were mapped to three diagnosis-related group (DRG) families consistent with PAD conditions: other vascular procedures (codes, 252-254), aortic and heart assist procedures (codes, 268, 269), and other major vascular procedures (codes, 270-272). Patients undergoing outpatient or office-based procedures were included if the claims data were inclusive of the HCPC procedure codes. Emergent procedures, patients with end-stage renal disease, and patients undergoing interventions within the 30 days preceding the index procedure were excluded. The analysis included usage of postacute care services (PACS) and 90-day postdischarge events (PDEs). PACS are defined as rehabilitation, skilled nursing facility, and home health services. PDEs included emergency department visits, observation stays, inpatient readmissions, and reinterventions. RESULTS: A total of 123,180 cases were included. Of these 123,180 cases, 82% had been performed in the outpatient setting. The Medicare expenditures for all periprocedural services provided at the index procedure (ie, professional, technical, and facility fees) were higher in the inpatient setting, with an average reimbursement per index case of $18,755, $34,600, and $25,245 for DRG codes 252 to 254, DRG codes 268 and 269, and DRG codes 270 to 272, respectively. Outpatient facility interventions had an average reimbursement of $11,458, and office-based index procedures had costs of $11,533. PACS were more commonly used after inpatient index procedures. In the inpatient setting, PACS usage and reimbursement were 58.6% ($5338), 57.2% ($4192), and 55.9% ($5275) for DRG codes 252 to 254, DRG codes 268 and 269, and DRG codes 270 to 272, respectively. Outpatient facility cases required PACS for 13.7% of cases (average cost, $1352), and office-based procedures required PACS in 15% of cases (average cost, $1467). The 90-day PDEs were frequent across all sites of service (range, 38.9%-50.2%) and carried significant costs. Readmission was associated with the highest average PDE expenditure (range, $13,950-$18.934). The average readmission Medicare reimbursement exceeded that of the index procedures performed in the outpatient setting. CONCLUSIONS: The cost of PAD interventions extends beyond the index procedure and includes relevant spending during the long postoperative period. Despite the analysis challenges related to the breadth of vascular procedures and the site of service variability, the data identified potential cost-saving opportunities in the management of costly PDEs. Because of the vulnerability of the PAD patient population, alternative payment modeling using a bundled value-based approach will require reallocation of resources to provide longitudinal patient care extending beyond the initial intervention.

Telemedicine platforms and their use in the coronavirus disease-19 era to deliver comprehensive vascular care.

Implementation of telemedicine for patient encounters optimizes personal safety and allows for continuity of patient care. Embracing telehealth reduces the use of personal protective equipment and other resources consumed during in-person visits. The use of telehealth has increased to historic levels in response to the coronavirus disease 2019 (COVID-19) pandemic. Telehealth may be a key modality to fight against COVID-19, allowing us to take care of patients, conserve personal protective equipment, and protect health care workers all while minimizing the risk of viral spread. We must not neglect vascular health issues while the coronavirus pandemic continues to flood many hospitals and keep people confined to their homes. Patients are not immune to diseases and illnesses such as stroke, critical limb ischemia, and deep vein thrombosis while being confined to their homes and afraid to visit hospitals. Emerging from the COVID-19 crisis, incorporating telemedicine into routine medical care is transformative. By leveraging digital technology, the authors discuss their experience with the implementation, workflow, coding, and reimbursement issues of telehealth during the COVID-19 era.

The Society for Vascular Surgery Alternative Payment Model Task Force report on opportunities for value-based reimbursement in care for patients with peripheral artery disease.

The Society for Vascular Surgery Alternative Payment Model (APM) Taskforce document explores the drivers and implications for developing objective value-based reimbursement plans for the care of patients with peripheral arterial disease (PAD). The APM is a payment approach that highlights high-quality and cost-efficient care and is a financially incentivized pathway for participation in the Quality Payment Program, which aims to replace the traditional fee-for-service payment method. At present, the participation of vascular specialists in APMs is hampered owing to the absence of dedicated models. The increasing prevalence of PAD diagnosis, technological advances in therapeutic devices, and the increasing cost of care of the affected patients have financial consequences on care delivery models and population health. The document summarizes the existing measurement methods of cost, care processes, and outcomes using payor data, patient-reported outcomes, and registry participation. The document also evaluates the existing challenges in the evaluation of PAD care, including intervention overuse, treatment disparities, varied clinical presentations, and the effects of multiple comorbid conditions on the cost potentially attributable to the vascular interventionalist. Medicare reimbursement data analysis also confirmed the prolonged need for additional healthcare services after vascular interventions. The Society for Vascular Surgery proposes that a PAD APM should provide patients with comprehensive care using a longitudinal approach with integration of multiple key medical and surgical services. It should maintain appropriate access to diagnostic and therapeutic advancements and eliminate unnecessary interventions. It should also decrease the variability in care but must also consider the varying complexity of the presenting PAD conditions. Enhanced quality of care and physician innovation should be rewarded. In addition, provisions should be present within an APM for high-risk patients who carry the risk of exclusion from care because of the naturally associated high costs. Although the document demonstrates clear opportunities for quality improvement and cost savings in PAD care, continued PAD APM development requires the assessment of more granular data for accurate risk adjustment, in addition to largescale testing before public release. Collaboration between payors and physician specialty societies remains key.

Sex-Related Outcomes After Endovascular Aneurysm Repair Within the Global Registry for Endovascular Aortic Treatment.

BACKGROUND: Abdominal aortic aneurysms (AAAs) are more common in men. However, women have been shown to have more short- and long-term adverse outcomes after endovascular aneurysm repair. This disparity is thought to be multifactorial, including anatomical differences, hormonal differences, older age of presentation, and a greater degree of preoperative comorbidities. METHODS: A retrospective analysis that included data for 3,758 patients from the Global Registry for Endovascular Aortic Treatment (GREAT) was conducted. Patients were recruited into GREAT between August 2010 and October 2016 and received the Gore Excluder stent graft for infrarenal AAAs repair. Cox multivariate regression analyses were performed to analyze any reintervention and device-related intervention rates. RESULTS: Of the 3,758 patients, 3,220 were male (mean age 73 years) and 538 were female (mean age 75 years). Women had higher prevalence rates of chronic obstructive pulmonary disease (P < 0.0001) and renal insufficiency (P = 0.03), whereas men had higher rates of cardiovascular comorbidities. The AAAs in women were smaller in diameter with shorter and more angulated necks. Women did not experience a significantly higher rate of endoleaks but did exhibit higher reintervention rates, including reintervention for device-related issues. In terms of mortality, aorta-related mortality was most prevalent within the first 30 days after procedure in both sexes. CONCLUSIONS: Women were treated at an older age and had a more hostile aneurysmal anatomy. Although the mortality rates were lower in women, they had significantly higher rates of reintervention, and thus higher morbidity rates after endovascular aneurysm repair.

Sex as an independent risk factor for long-term survival after endovascular aneurysm repair.

BACKGROUND: Several vascular surgical procedures, including repair of abdominal aortic aneurysms (AAAs), show poorer outcomes for women than for men. We evaluated the impact of sex-based demographic differences on survival after endovascular aneurysm repair (EVAR). METHODS: We reviewed EVARs performed at our institution between 2003 and 2009 and assessed aortic neck variables (length, diameter, angulation, and calcification), iliac artery variables (length, tortuosity, angulation, and calcification), and AAA diameter. Cox proportional hazards models were used to examine the association between sex and 5-year mortality while adjusting for patients' demographics, comorbidities, anatomic variables, and AAA parameters. The final model adjusted for sex, age, body mass index, hypertension, iliac artery length, and aortic neck length. RESULTS: Of 336 patients, 278 were male (mean age, 73 years) and 58 were female (mean age, 77 years; P = .0005). Men had more coronary artery bypass grafts (79 vs 8; P = .02) and percutaneous coronary interventions (52 vs 4; P = .03) than women did. Significant differences between the sexes was seen for aortic neck angle, diameter, and length and for iliac artery diameter and length. Men (44%) were more likely than women (22%; P = .0002) to have EVAR performed within the device guidelines. Five-year survival was 73% in men and 49% in women. Multivariable analysis showed that female sex, increase in age, low body mass index (<25 kg/m2), and aortic neck length were significantly associated with risk of 5-year mortality. CONCLUSIONS: Women presented at an older age and with a more hostile anatomy. They had reduced survival compared with men after EVAR. After controlling for comorbidities and aortic neck and iliac artery anatomy, sex remained an independent predictor for survival.
