Practice patterns surrounding the use of tibial interventions for claudication in the Medicare population

OBJECTIVE

At present, no data are available to support the use of tibial interventions in the treatment of claudication. We characterized the practice patterns surrounding tibial peripheral vascular interventions (PVIs) for patients with claudication in the United States.

METHODS

Using 100% Medicare fee-for-service claims from 2017 to 2019, we conducted a retrospective analysis of all patients who underwent an index PVI for claudication. Patients with any previous PVI, acute limb ischemia, or chronic limb-threatening ischemia in the preceding 12 months were excluded. The primary outcome was the receipt or delivery of tibial revascularization during an index PVI for claudication, defined as tibial PVI with or without concomitant femoropopliteal PVI. Univariable comparisons and multivariable hierarchical logistic regression were used to assess the patient and physician characteristics associated with the use of tibial PVI for claudication.

RESULTS

Of 59,930 Medicare patients who underwent an index PVI for claudication between 2017 and 2019, 16,594 (27.7%) underwent a tibial PVI (isolated tibial PVI, 38.5%; tibial PVI with concomitant femoropopliteal PVI, 61.5%). Of the 1542 physicians included in our analysis, the median physician-level tibial PVI rate was 20.0% (interquartile range, 9.1%-37.5%). Hierarchical logistic regression suggested that patient-level characteristics associated with tibial PVI for claudication included male sex (adjusted odds ratio [aOR], 1.23), increasing age (aOR, 1.30-1.96), Black race (aOR, 1.47), Hispanic ethnicity (aOR, 1.86), diabetes (aOR, 1.36), no history of hypertension (aOR, 1.12), and never-smoking status (aOR, 1.64; P < .05 for all). Physician-level characteristics associated with tibial PVI for claudication included early-career status (aOR, 2.97), practice location in the West (aOR, 1.75), high-volume PVI practice (aOR, 1.87), majority of practice in an ambulatory surgery center or office-based laboratory setting (aOR, 2.37), and physician specialty. The odds of vascular surgeons performing tibial PVI were significantly lower compared with radiologists (aOR, 2.98) and cardiologists (aOR, 1.67; P < .05 for all). The average Medicare reimbursement per patient was dramatically higher for physicians performing high rates of tibial PVI (quartile 4 vs quartile 1-3, $12,023.96 vs $692.31 per patient; P < .001).

CONCLUSIONS

Tibial PVI for claudication was performed more often by nonvascular surgeons in high-volume practices and high-reimbursement settings. Thus, a critical need exists to reevaluate the indications, education, and reimbursement policies surrounding these procedures.

Patient safety indicators from a spine surgery perspective: the importance of a specialty specific clinician working with the documentation team and the impact to your hospital

BACKGROUND CONTEXT

The Hospital Acquired Conditions (HAC) Reduction Program supports the Centers for Medicare and Medicaid Services (CMS) effort to prevent harm to patients by providing a financial incentive to reduce HACs. HAC scores are impacted by Patient Safety Indicators (PSIs), potentially preventable hospital-related events associated with harmful patient outcomes. PSIs are identified using International Classification of Diseases (ICD) coding; however, ICD coding does not always reflect the patient's true medical course.

PURPOSE

To evaluate the efficacy of and costs savings associated with a clinical documentation review process in tandem with clinician collaboration in identifying incorrectly generated PSIs.

STUDY DESIGN

Retrospective chart review.

PATIENT SAMPLE

All patients undergoing spine surgery at a single multi-surgeon tertiary spine center.

OUTCOME MEASURES

Occurrence of PSI.

METHODS

Over two 11-month periods, all PSIs attributable to spine surgery were determined. The number and type of spine related PSIs were compared before (Control) and after the implementation of a specialty specific clinical review (Intervention) to identify incorrectly generated PSIs. The financial impact of this intervention was calculated in the form of an annual cost savings to our hospital system.

RESULTS

During the Control phase, 61 PSIs were reported in 3368 spine cases, representing a total of 3.6 PSIs/month. During Intervention phase, 26 PSIs in 4,482 spine cases, resulting in a statistically significant decrease of 1.5 PSIs per month. The percentage of PSIs across all surgical cases attributable to spine surgery had a statistically significant decrease during the Intervention period compared to the Control period (16% vs. 10%, p=.034), resulting in the avoidance of a 1% CMS cost reduction, an annual cost saving of approximately $3-4 million dollars per year.

CONCLUSIONS

The implementation of a clinical documentation review process with clinician collaboration to ensure ICD-10 coding accurately reflects the patient's medical course leads to more accurate PSI reporting, with the potential for substantial cost-savings for hospitals from CMS reimbursement.

Translating improved quality of care into an improved quality of life for patients with inflammatory bowel disease

The term quality of care has been interpreted in different ways in medicine. Skeptics of the quality movement insist that checkboxes and government and payer oversight will not lead to better patient outcomes. Supporters refer to areas in medicine in which quality improvement efforts have led to improved survival, such as in cystic fibrosis and cardiovascular disease. For quality improvement to be effective, the process demands rigorous documentation, analysis, feedback, and behavioral change. This requires valid metrics and mechanisms to provide dynamic point-of-care (or close to point of care) feedback in a manner that drives improvement. For inflammatory bowel disease, work has been performed in Europe and the United States to develop a framework for how practitioners can improve quality of care. Improve Care Now has created a sophisticated quality improvement program for pediatric patients with inflammatory bowel disease. The American Gastroenterology Association has worked within the National Quality Strategy framework to develop quality measures for patients with inflammatory bowel disease that have been incorporated into Federal programs that are moving Medicare reimbursement from a volume-based to a value-based structure. The Crohn's and Colitis Foundation of America is initiating a quality intervention program that can be implemented in community and academic practices to stimulate continual improvement processes for patients with inflammatory bowel disease. All of this work is intended to make quality improvement programs both feasible and useful, with the ultimate goal of improving quality of life for our patients.
