Influence of podiatry on orthopedic surgery at a level I trauma center

The Opportunity for Impactful Integration of Vascular and Podiatric Care

BACKGROUND

The importance of collaboration between vascular and podiatric surgeons has been well-established. High-level partnerships are integral to the development of multidisciplinary programs and wound care centers, ultimately resulting in improved patient outcomes. This vascular-podiatric integration is not universal, however, and podiatric surgery may not be aligned within a vascular surgery division at many institutions. As one such institution, we reviewed our single-center experience in order to identify opportunities for the impactful integration of vascular-podiatric patient care.

METHODS

Institutional electronic medical records were retrospectively reviewed for all procedures performed by vascular surgeons at a high volume, safety-net academic medical center. Data were collected on all primary and additional procedures, current procedural terminology (CPT) codes, case type (elective, urgent, emergent), surgeon specialty, and date/time of the procedures performed. CPT codes were linked to the Centers for Medicare & Medicaid Services' Physician Fee Schedule to estimate the work relative value unit (wRVU) per procedure.

RESULTS

From 2018 to 2022, vascular surgeons performed a total of 12,206 operations, of which 1102 (9.9%) involved podiatric procedures. The most common vascular-performed podiatry procedures performed were toe amputations (38.1%, n = 420), transmetatarsal foot amputations (20.1%, n = 222), and ankle/foot debridement (16.2%, n = 178). Foot/ankle-specific procedures were identified as the primary procedure in 726 (65.9%) cases and as the adjunct procedure in 376 (34.1%) cases. A substantial proportion of podiatric procedures occurred on an urgent (n = 278, 25.2%) or emergent (n = 28, 2.5%) basis. A total of 163 (14.8%) cases occurred after hours (either before 0600 or after 1800), and 133 (12.1%) cases were performed on a holiday or weekend. Procedure-specific revenue included 4243.39 wRVU for primary procedures and 2108.08 wRVU for additional procedures performed.

CONCLUSIONS

We report our single-center experience in which vascular surgeons provide a significant proportion of podiatric procedures. Our study underscores the potential for integrating podiatric surgeons within a vascular surgical division and presents opportunities for collaboration and enhanced patient care.

A Survey Analysis of Patient Understanding and Preferences for Podiatrists Versus Foot and Ankle Orthopaedic Surgeons

BACKGROUND

Recent studies suggest poorer outcomes and higher costs associated with patients treated by podiatrists, yet no studies have evaluated patient perception and preference for foot and ankle providers. This study aims to determine patient perception of training for podiatrists compared to orthopaedic surgeons and patient preference for type of provider seen.

METHODS

A 20-question survey was administered to new patients seeing either a podiatrist or foot and ankle orthopaedic surgeon. Questions pertained to demographics, patient knowledge of their provider, perception of training requirements, number of years in professional training, and differences in surgical volume during training. Patients were asked their preference for a particular type of foot and ankle provider, and whether they perceived a difference in surgical skillset or a provider's ability to manage different pathology.

RESULTS

In all, 147 podiatry and 115 orthopaedic patients were included in the study. Demographics were similar between groups. Both groups believed orthopedists required more years of education and surgical training. In all, 61.5% of orthopaedic patients believed that orthopedists performed more foot and ankle surgeries and were more skilled as compared to podiatrists, while only about a third of podiatry patients believed this to be true (68.7% vs 38.6%; P < .001). Most patients believed orthopedists were more skilled in treating fractures. In all, 48.7% of orthopaedic patients preferred seeing an orthopedist compared to only 3.5% of podiatry patients.

CONCLUSIONS

Our study demonstrates that patients are knowledgeable about the type of foot and ankle provider they are seeing. Most patients believe orthopaedic surgeons require more years of education and surgical training compared to podiatrists and believe they are more skilled in fracture-related surgery. Fewer podiatry patients expressed a preference for an orthopaedic surgeon. Providers must play an active role in discussing their training background prior to treating foot and ankle patients, especially in the setting of fracture-related pathology.

CLINICAL RELEVANCE

This study demonstrates that most patients seeking care from a podiatrist or foot and ankle orthopaedic surgeon are relatively knowledgeable about the type of provider they are seeing; however, there are some differences. Most patients understand that orthopaedic surgeons require more years of education and surgical training and also believe orthopaedic surgeons are more skilled in fracture work and taking care of arthritic conditions. In general, podiatry patients have less preference for seeing an orthopaedic surgeon; however, many of these patients are seeking care for wounds and infections. With expanding roles and scope of practice among podiatry providers, it is important that providers become more active in explaining their training background and qualifications when treating foot and ankle conditions.

Demographic Distribution of Foot and Ankle Surgeries Among Orthopaedic Surgeons and Podiatrists: A 10-Year Database Retrospective Study

BACKGROUND

Foot and ankle surgeries in the United States (US) are currently performed by orthopaedic surgeons or podiatrists with specialty surgical training. With the trend in healthcare now placing increased emphasis on quality and standardizing patient care, this study aimed to characterize the distribution, volume, and trends of certain foot and ankle surgeries performed in the US by both orthopaedic surgeons and podiatrists.

MATERIALS AND METHODS

A retrospective analysis was performed using the Marketscan Claims Database (Truven Health Analytics, Ann Arbor, Michigan) which covers most privately insured patients under the age of 65 in the USA from 2005 to 2014. We searched current procedural terminology (CPT) codes for total ankle replacement (TAR), triple arthrodesis, hallux valgus correction, pilon fracture open reduction and internal fixation (ORIF), calcaneus fracture ORIF, and ankle fracture ORIF. We recorded the timing and nature of procedures along with various features associated with the surgeon and the geographic location of the treatment facility.

RESULTS

We found that the number of foot and ankle procedures performed annually is steadily increasing. Orthopaedic surgeons are the main treating surgeon for common foot and ankle traumatic conditions or complex hind foot cases like TAR. On the other hand, our study showed that podiatrists perform almost 9 out of 10 hallux valgus correction surgeries.

DISCUSSION

Our study showed the trends in surgical volumes and differences between surgical podiatrists and orthopaedic surgeons and the evolution of these volumes over a ten year period and differences in surgical repertoire between orthopaedists and podiatrists.Levels of Evidence: Level IV: Case series, Clinical research.

Orthopedic Versus Podiatric Care of the Foot and Ankle: A Literature Review

As the scope of podiatric surgery expands, the relative roles and outcomes of orthopedic surgeons and podiatrists need to be defined. With growing demand for foot and ankle services, the roles of podiatrists and orthopedic surgeons are increasingly overlapping. Few studies have examined the overlapping scope of practice of each of the groups or compared the relative costs and outcomes associated with each.

Lower Complication Rate Following Ankle Fracture Fixation by Orthopaedic Surgeons Versus Podiatrists

INTRODUCTION

Increased overlap in the scope of practice between orthopaedic surgeons and podiatrists has led to increased podiatric treatment of foot and ankle injuries. However, a paucity of studies exists in the literature comparing orthopaedic and podiatric outcomes following ankle fracture fixation.

METHODS

Using an insurance claims database, 11,745 patients who underwent ankle fracture fixation between 2007 and 2015 were retrospectively evaluated. Patient data were analyzed based on the provider type. Complications were identified by the International Classification of Diseases, Ninth Revision, codes, and revision surgeries were identified by the Current Procedural Terminology codes. Complications analyzed included malunion/nonunion, infection, deep vein thrombosis, and rates of irrigation and débridement. Risk factors for complications were compared using the Charlson Comorbidity Index.

RESULTS

Overall, 11,115 patients were treated by orthopaedic surgeons and 630 patients were treated by podiatrists. From 2007 to 2015, the percentage of ankle fractures surgically treated by podiatrists had increased, whereas that treated by orthopaedic surgeons had decreased. Surgical treatment by podiatrists was associated with higher malunion/nonunion rates among all types of ankle fractures. No differences in complications were observed in patients with unimalleolar fractures. In patients with bimalleolar or trimalleolar fractures, treatment by a podiatrist was associated with higher malunion/nonunion rates. Patients treated by orthopaedic surgeons versus podiatrists had similar comorbidity profiles.

DISCUSSION

Surgical treatment of ankle fractures by orthopaedic surgeons was associated with lower rates of malunion/nonunion when compared with that by podiatrists. The reasons for these differences are likely multifactorial but warrants further investigation. Our findings have important implications in patients who must choose a surgeon to surgically manage their ankle fracture, as well as policymakers who determine the scope of practice.

Cost Determinants in the 90-Day Management of Isolated Ankle Fractures at a Large Urban Academic Hospital

OBJECTIVES

To determine the independent risk factors associated with increasing costs and unplanned hospital readmissions in the 90-day episode of care (EOC) for isolated operative ankle fractures at our institution.

DESIGN

Retrospective cohort study.

SETTING

Level I Trauma Center.

PATIENTS

Two hundred ninety-nine patients undergoing open reduction internal fixation for the treatment of an acute, isolated ankle fracture between 2010 and 2015.

INTERVENTION

None.

MAIN OUTCOME MEASURES

Independent risk factors for increasing 90-day EOC costs and unplanned hospital readmission rates.

RESULTS

Orthopaedic (64.9%) and podiatry (35.1%) patients were included. The mean index admission cost was $14,048.65 ± $5,797.48. Outpatient cases were significantly cheaper compared to inpatient cases ($10,164.22 ± $3,899.61 vs. $15,942.55 ± $5,630.85, respectively, P < 0.001). Unplanned readmission rates were 5.4% (16/299) and 6.7% (20/299) at 30 and 90 days, respectively, and were often (13/20, 65.0%) due to surgical site infections. Independent risk factors for unplanned hospital readmissions included treatment by the podiatry service (P = 0.024) and an American Society of Anesthesiologists score of ≥3 (P = 0.017). Risk factors for increasing total postdischarge costs included treatment by the podiatry service (P = 0.011) and male gender (P = 0.046).

CONCLUSIONS

Isolated operative ankle fractures are a prime target for EOC cost containment strategy protocols. Our institutional cost analysis study suggests that independent financial clinical risk factors in this treatment cohort includes podiatry as the treating surgical service and patients with an American Society of Anesthesiologists score ≥3, with the former also independently increasing total postdischarge costs in the 90-day EOC. Outpatient procedures were associated with about a one-third reduction in total costs compared to the inpatient subgroup.
