Economic value of podiatry service in limb salvage alliance.

OBJECTIVE/BACKGROUND: 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. METHODS: 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 3 years, 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. RESULTS: The limb salvage program experienced >100% of growth in total OR volumes, clinic encounters, and total wRVUs over a period of 4 years. 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 3 years. 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. CONCLUSIONS: 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.

Medicare Support for Dental and Podiatry Graduate Medical Education Programs.

Importance: Oral health care faces ongoing workforce challenges that affect patient access and outcomes. While the Medicare program provides an estimated $14.6 billion annually in graduate medical education (GME) payments to teaching hospitals, including explicit support for dental and podiatry programs, little is known about the level or distribution of this public investment in the oral health and podiatry workforce. Objective: To examine Medicare GME payments to teaching hospitals for dental and podiatry residents from 1998 to 2018, as well as the distribution of federal support among states, territories, and the District of Columbia. Design, Setting, and Participants: This cross-sectional study was conducted using data from 1252 US teaching hospitals. Data were analyzed from May through August 2020. Exposures: Dental and podiatry residency training. Main Outcomes and Measures: Medicare dental and podiatry GME payments were examined. Results: Among 1252 teaching hospitals, Medicare provided nearly $730 million in dental and podiatry GME payments in 2018. From 1998 to 2018, the number of residents supported more than doubled, increasing from 2340 residents to 4856 residents, for a 2.1-fold increase, while Medicare payments for dental and podiatry GME increased from $279 950 531 to $729 277 090, for a 2.6-fold increase. In 2018, an estimated 3504 of 4856 supported positions (72.2%) were dental. Medicare GME payments varied widely among states, territories, and the District of Columbia, with per capita payments by state, territory, and district population ranging from $0.05 in Puerto Rico to $14.24 in New York, while 6 states received no support for dental or podiatry residency programs. Conclusions and Relevance: These findings suggest that dental and podiatry GME represents a substantial public investment, and deliberate policy decisions are needed to target this nearly $730 million and growing investment to address the nation's priority oral and podiatry health needs.

Technology-enabled remote management of diabetes foot disease and potential for reduction in associated health costs: a pilot study.

Diabetes-related foot disease, particularly when associated with amputation, affects quality of life and has a significant impact on health care costs. A pilot study using enhanced technology to facilitate remote access and video conferencing from rural locations to the diabetes MDT through a new service pathway confirmed high levels of patient satisfaction with 89% of foot ulcers improved or stable and only two minor amputations. A health economic analysis suggested potential for significant cost savings if this was scaled up regionally. Further evaluation of an integrated pathway, impact on lower limb amputation rates and full health economic assessment is recommended.

The foot-health of people with diabetes in regional and rural Australia: baseline results from an observational cohort study.

BACKGROUND: There is limited Australian epidemiological research that reports on the foot-health characteristics of people with diabetes, especially within rural and regional settings. The objective of this study was to explore the associations between demographic, socio-economic and diabetes-related variables with diabetes-related foot morbidity in people residing in regional and rural Australia. METHODS: Adults with diabetes were recruited from non-metropolitan Australian publicly-funded podiatry services. The primary variable of interest was the University of Texas diabetic foot risk classification designated to each participant at baseline. Independent risk factors for diabetes-related foot morbidity were identified using multivariable analysis. RESULTS: Eight-hundred and ninety-nine participants enrolled, 443 (49.3%) in Tasmania and 456 (50.7%) in Victoria. Mean age was 67 years (SD 12.7), 9.2% had type 1 diabetes, 506 (56.3%) were male, 498 (55.4%) had diabetes for longer than 10 years and 550 (61.2%) either did not know the ideal HbA1c target or reported that it was ≥7.0. A majority had peripheral neuropathy or worse foot morbidity (61.0%). Foot morbidity was associated with male sex (OR 2.42, 95% CI 1.82-3.22), duration of diabetes > 20 years (OR 3.25, 95% CI 2.22-4.75), and Tasmanian residence (OR 3.38, 95% CI 2.35-4.86). CONCLUSIONS: A high proportion of the regional Australian clinical population with diabetes seen by the publicly-funded podiatric services in this study were at high risk of future limb threatening foot morbidity, and participants residing in Northern Tasmania are more likely to have worse diabetes-related foot morbidity than those from regional Victoria. Service models should be reviewed to ensure that diabetes-related foot services are appropriately developed and resourced to deliver interdisciplinary evidence-based care.

Cost-Effectiveness of a Multifaceted Podiatry Intervention for the Prevention of Falls in Older People: The REducing Falls with Orthoses and a Multifaceted Podiatry Intervention Trial Findings.

BACKGROUND: Falls are a major cause of morbidity among older people. Multifaceted interventions may be effective in preventing falls and related fractures. OBJECTIVE: To evaluate the cost-effectiveness alongside the REducing Falls with Orthoses and a Multifaceted podiatry intervention (REFORM) trial. METHODS: REFORM was a pragmatic multicentre cohort randomised controlled trial in England and Ireland; 1,010 participants (> 65 years) were randomised to receive either a podiatry intervention (n = 493), including foot and ankle strengthening exercises, foot orthoses, new footwear if required, and a falls prevention leaflet, or usual podiatry treatment plus a falls prevention leaflet (n = 517). PRIMARY OUTCOME: incidence of falls per participant in the 12 months following randomisation. SECONDARY OUTCOMES: proportion of fallers and quality of life (EQ-5D-3L) which was converted into quality-adjusted life years (QALYs) for each participant. Differences in mean costs and QALYs at 12 months were used to assess the cost-effectiveness of the intervention relative to usual care. Cost-effectiveness analyses were conducted in accordance with National Institute for Health and Clinical Excellence reference case standards, using a regression-based approach with costs expressed in GBP (2015 price). The base case analysis used an intention-to-treat approach on the imputed data set using multiple imputation. RESULTS: There was a small, non-statistically significant reduction in the incidence rate of falls in the intervention group (adjusted incidence rate ratio 0.88, 95% CI 0.73-1.05, p = 0.16). Participants allocated to the intervention group accumulated on average marginally higher QALYs than the usual care participants (mean difference 0.0129, 95% CI -0.0050 to 0.0314). The intervention costs were on average GBP 252 more per participant compared to the usual care participants (95% CI GBP -69 to GBP 589). Incremental cost-effectiveness ratios ranged between GBP 19,494 and GBP 20,593 per QALY gained, below the conventional National Health Service cost-effectiveness thresholds of GBP 20,000 to GBP 30,000 per additional QALY. The probability that the podiatry intervention is cost-effective at a threshold of GBP 30,000 per QALY gained was 0.65. The results were robust to sensitivity analyses. CONCLUSION: The benefits of the intervention justified the moderate cost. The intervention could be a cost-effective option for falls prevention when compared with usual care in the UK.

The integration of a Podiatrist into an orthopaedic department: a cost-consequences analysis.

BACKGROUND: The aim of this study was to evaluate the cost-consequences of a podiatry-led triage clinic provided in an orthopaedic department relative to usual care for non-urgent foot and ankle complaints in an Australian tertiary care hospital. METHODS: All new, non-urgent foot and ankle patients seen in an outpatient orthopaedic department were included in this study. The patients seen between 2014 and 2015 by Orthopaedic Surgeons were considered 'usual care', the patients seen between 2015 and 2016 by a Podiatrist were considered the 'Podiatry Triage Clinic'. Data on new and review patient appointments; the number of new patients / session; the number of appointments / patient; the number of patients discharged; the surgical conversion rate; staff time; and imaging use were collected. A cost-consequences analysis, undertaken from a healthcare provider perspective (hospital) estimated the incremental resource use, costs and effects of the Podiatry Triage Clinic relative to usual care over a 12-month period. RESULTS: The Orthopaedic Surgeons and Podiatrist consulted with 72 and 212 new patients during the usual care and triage periods, respectively. The Podiatrist consulted with more new patients / session, mean (SD) of 3.6 (1.0) versus 0.7 (0.8), p < 0.001 and utilised less appointments / patient than the Orthopaedic Surgeons, mean (SD) of 1.3 (0.6) versus 1.9 (1.1), p < 0.001. The percentage of patients discharged without surgery was similar in the Podiatry Triage Clinic and usual care, 80.3% and 87.5% p = 0.135, respectively, but the surgical conversion rate was higher in the Podiatry Triage Clinic, 76.1% versus 12.5% p < 0.001. The total integrated appointment cost for the 12-month usual care period was $32,744, which represented a cost of $454.78 / patient. The total appointment and imaging cost during the triage period was $19,999, representing $94.34 / patient. Further analysis, suggests that the projected annual saving of integrating a Podiatry Triage Clinic versus an orthopaedic clinic alone is $50,441. CONCLUSIONS: The integration of a Podiatrist into an orthopaedic department significantly increases the number of patients seen, is cost-effective, improves the surgical conversion rate and improves the utilisation of Orthopaedic Surgeons.

Determinants of midterm functional outcomes, wound healing, and resources used in a hospital-based limb preservation program.

OBJECTIVE: The objective of this study was to assess midterm functional status, wound healing, and in-hospital resource use among a prospective cohort of patients treated in a tertiary hospital, multidisciplinary Center for Limb Preservation. METHODS: Data were prospectively gathered on all consecutive admissions to the Center for Limb Preservation from July 2013 to October 2014 with follow-up data collection through January 2016. Limbs were staged using the Society for Vascular Surgery Wound, Ischemia, and foot Infection (WIfI) threatened limb classification scheme at the time of hospital admission. Patients with nonatherosclerotic vascular disorders, acute limb ischemia, and trauma were excluded. RESULTS: The cohort included 128 patients with 157 threatened limbs; 8 limbs with unstageable disease were excluded. Mean age (±standard deviation [SD]) was 66 (±13) years, and median follow-up duration (interquartile range) was 395 (80-635) days. Fifty percent (n = 64/128) of patients were readmitted at least once, with a readmission rate of 20% within 30 days of the index admission. Mean total number of admissions per patient (±SD) was 1.9 ± 1.2, with mean (±SD) cumulative length of stay (cLOS) of 17.1 (±17.9) days. During follow-up, 25% of limbs required a vascular reintervention, and 45% developed recurrent wounds. There was no difference in the rate of readmission, vascular reintervention, or wound recurrence by initial WIfI stage (P > .05). At the end of the study period, 23 (26%) were alive and nonambulatory; in 20%, functional status was missing. On both univariate and multivariate analysis, end-stage renal disease and prior functional status predicted ability to ambulate independently (P < .05). WIfI stage was associated with major amputation (P = .01) and cLOS (P = .002) but not with time to wound healing. Direct hospital (inpatient) cost per limb saved was significantly higher in stage 4 patients (P < .05 for all time periods). WIfI stage was associated with cumulative in-hospital costs at 1 year and for the overall follow-up period. CONCLUSIONS: Among a population of patients admitted to a tertiary hospital limb preservation service, WIfI stage was predictive of midterm freedom from amputation, cLOS, and hospital costs but not of ambulatory functional status, time to wound healing, or wound recurrence. Patients presenting with limb-threatening conditions require significant inpatient care, have a high frequency of repeated hospitalizations, and are at significant risk for recurrent wounds and leg symptoms at later times. Stage 4 patients require the most intensive care and have the highest initial and aggregate hospital costs per limb saved. However, limb salvage can be achieved in these patients with a dedicated multidisciplinary team approach.

Partnerships between podiatrists and vascular surgeons in building effective wound care centers.

This practice memo, a collaborative effort between the Young Physicians' Program of the American Podiatric Medical Association and the Young Surgeons Committee of the Society for Vascular Surgery, is intended to aid podiatrists and vascular surgeons in the early years of their respective careers, especially those involved in the care of patients with chronic wounds. During these formative years, learning how to successfully establish an interprofessional partnership is crucial to provide the best possible care to this important population of patients.

Clinical effectiveness and cost-effectiveness of a multifaceted podiatry intervention for falls prevention in older people: a multicentre cohort randomised controlled trial (the REducing Falls with ORthoses and a Multifaceted podiatry intervention trial).

BACKGROUND: Falls are a serious cause of morbidity and cost to individuals and society. Evidence suggests that foot problems and inappropriate footwear may increase the risk of falling. Podiatric interventions could help reduce falls; however, there is limited evidence regarding their clinical effectiveness and cost-effectiveness. OBJECTIVES: To determine the clinical effectiveness and cost-effectiveness of a multifaceted podiatry intervention for preventing falls in community-dwelling older people at risk of falling, relative to usual care. DESIGN: A pragmatic, multicentred, cohort randomised controlled trial with an economic evaluation and qualitative study. SETTING: Nine NHS trusts in the UK and one site in Ireland. PARTICIPANTS: In total, 1010 participants aged ≥ 65 years were randomised (intervention, n = 493; usual care, n = 517) via a secure, remote service. Blinding was not possible. INTERVENTIONS: All participants received a falls prevention leaflet and routine care from their podiatrist and general practitioner. The intervention also consisted of footwear advice, footwear provision if required, foot orthoses and foot- and ankle-strengthening exercises. MAIN OUTCOME MEASURES: The primary outcome was the incidence rate of falls per participant in the 12 months following randomisation. The secondary outcomes included the proportion of fallers and multiple fallers, time to first fall, fear of falling, fracture rate, health-related quality of life (HRQoL) and cost-effectiveness. RESULTS: The primary analysis consisted of 484 (98.2%) intervention and 507 (98.1%) usual-care participants. There was a non-statistically significant reduction in the incidence rate of falls in the intervention group [adjusted incidence rate ratio 0.88, 95% confidence interval (CI) 0.73 to 1.05; p = 0.16]. The proportion of participants experiencing a fall was lower (50% vs. 55%, adjusted odds ratio 0.78, 95% CI 0.60 to 1.00; p = 0.05). No differences were observed in key secondary outcomes. No serious, unexpected and related adverse events were reported. The intervention costs £252.17 more per participant (95% CI -£69.48 to £589.38) than usual care, was marginally more beneficial in terms of HRQoL measured via the EuroQoL-5 Dimensions [mean quality-adjusted life-year (QALY) difference 0.0129, 95% CI -0.0050 to 0.0314 QALYs] and had a 65% probability of being cost-effective at the National Institute for Health and Care Excellence threshold of £30,000 per QALY gained. The intervention was generally acceptable to podiatrists and trial participants. LIMITATIONS: Owing to the difficulty in calculating a sample size for a count outcome, the sample size was based on detecting a difference in the proportion of participants experiencing at least one fall, and not the primary outcome. We are therefore unable to confirm if the trial was sufficiently powered for the primary outcome. The findings are not generalisable to patients who are not receiving podiatry care. CONCLUSIONS: The intervention was safe and potentially effective. Although the primary outcome measure did not reach significance, a lower fall rate was observed in the intervention group. The reduction in the proportion of older adults who experienced a fall was of borderline statistical significance. The economic evaluation suggests that the intervention could be cost-effective. FUTURE WORK: Further research could examine whether or not the intervention could be delivered in group sessions, by physiotherapists, or in high-risk patients.

Medical and Economic Impact of a Free Student-Run Podiatric Medical Clinic A Preliminary Analysis.

BACKGROUND: Data from the free student-run podiatric medical clinic at Clínica Tepati at the University of California, Davis, were used to analyze medical and economic impacts on health-care delivery and to extrapolate the economic impact to the national level. Clínica Tepati also provides an excellent teaching environment and services to the uninsured Hispanic population in the Greater Sacramento area. METHODS: In this analysis, we retrospectively reviewed patient medical records for podiatric medical encounters during 15 clinic days between November 2010 and February 2012. The economic impact was evaluated by matching diagnoses and treatments with Medicare reimbursement rates using International Classification of Diseases codes, Current Procedural Terminology codes, and the prevailing Medicare reimbursement rates. RESULTS: Sixty-three podiatric medical patients made 101 visits during this period. Twenty patients returned to the clinic for at least one follow-up visit or for a new medical concern. Thirty-nine different diagnoses were identified, and treatments were provided for all 101 patient encounters/visits. Treatments were limited to those within the clinic's resources. This analysis estimates that $17,332.13 worth of services were rendered during this period. CONCLUSIONS: These results suggest that the free student-run podiatric medical clinic at Clínica Tepati had a significant medical and economic impact on the delivery of health care at the regional level, and when extrapolated, nationally as well. These student-run clinics also play an important role in medical education settings.

Effectiveness of off-the-shelf footwear in reducing foot pain in Australian Department of Veterans' Affairs recipients not eligible for medical grade footwear: study protocol for a randomized controlled trial.

BACKGROUND: Foot pain is highly prevalent in older people, and in many cases is associated with wearing inadequate footwear. In Australia, the Department of Veterans' Affairs (DVA) covers the costs of medical grade footwear for veterans who have severe foot deformity. However, there is a high demand for footwear by veterans with foot pain who do not meet this eligibility criterion. Therefore, this article describes the design of a randomized controlled trial to evaluate the effectiveness of low cost, off-the-shelf footwear in reducing foot pain in DVA recipients who are currently not eligible for medical grade footwear. METHODS: One hundred and twenty DVA clients with disabling foot pain residing in Melbourne, Australia, who are not eligible for medical grade footwear will be recruited from the DVA database, and will be randomly allocated to an intervention group or a 'usual care' control group. The intervention group will continue to receive their usual DVA-subsidized podiatry care in addition to being provided with low-cost, supportive footwear (Dr Comfort®, Vasyli Medical, Labrador, Queensland, Australia). The control group will also continue to receive DVA-subsidized podiatry care, but will not be provided with the footwear until the completion of the study. The primary outcome measure will be pain subscale on the Foot Health Status Questionnaire (FHSQ), measured at baseline and 4, 8, 12 and 16 weeks. Secondary outcome measures measured at baseline and 16 weeks will include the function subscale of the FHSQ, the Manchester Foot Pain and Disability Index, the number of DVA podiatry treatments required during the study period, general health-related quality of life (using the Short Form 12® Version 2.0), the number of falls experienced during the follow-up period, the Timed Up and Go test, the presence of hyperkeratotic lesions (corns and calluses), the number of participants using co-interventions to relieve foot pain, and participants' perception of overall treatment effect. Data will be analyzed using the intention-to-treat principle. DISCUSSION: This study is the first randomized controlled trial to evaluate the effectiveness of off-the-shelf footwear in reducing foot pain in DVA recipients. The intervention has been pragmatically designed to ensure that the study findings can be implemented into policy and clinical practice if found to be effective.

2012 financial outlook: physicians and podiatrists.

Although the nationally unadjusted average Medicare allowable rates have not increased or decreased significantly, the new codes, the new coding regulations, the NCCI edits, and the Medicare contractors' local coverage determinations (LCDs) will greatly impact physicians' and podiatrists' revenue in 2012. Therefore, every wound care physician and podiatrist should take the time to update their charge sheets and their data entry systems with correct codes, units, and appropriate charges (that account for all the resources needed to perform each service or procedure). They should carefully read the LCDs that are pertinent to the work they perform. If the LCDs contain language that is unclear or incorrect, physicians and podiatrists should contact the Medicare contractor medical director and request a revision through the LCD Reconsideration Process. Medicare has stabilized the MPFS allowable rates for 2012-now physicians and podiatrists must do their part to implement the new coding, payment, and coverage regulations. To be sure that the entire revenue process is working properly, physicians and podiatrists should conduct quarterly, if not monthly, audits of their revenue cycle. Healthcare providers will maintain a healthy revenue cycle by conducting internal audits before outside auditors conduct audits that result in repayments that could have been prevented.

The economic value of specialized lower-extremity medical care by podiatric physicians in the treatment of diabetic foot ulcers.

BACKGROUND: We sought to examine the economic value of specialized lower-extremity medical care by podiatric physicians in the treatment of diabetic foot ulcers by evaluating cost outcomes for patients with diabetic foot ulcer who did and did not receive care from a podiatric physician in the year before the onset of a foot ulcer. METHODS: We analyzed the economic value among commercially insured patients and Medicare-eligible patients with employer-sponsored supplemental medical benefits using the MarketScan Databases. The analysis consisted of two parts. In part I, we examined cost or savings per patient associated with care by podiatric physicians using propensity score matching and regression techniques; in part II, we extrapolated cost or savings to populations. RESULTS: Matched and regression-adjusted results indicated that patients who visited a podiatric physician had $13,474 lower costs in commercial plans and $3,624 lower costs in Medicare plans during 2-year follow-up (P < .01 for both). A positive net present value of increasing the share of patients at risk for diabetic foot ulcer by 1% was found, with a range of $1.2 to $17.7 million for employer-sponsored plans and $1.0 to $12.7 million for Medicare plans. CONCLUSIONS: These findings suggest that podiatric medical care can reduce the disease and economic burdens of diabetes.

Podiatric medicine: a current assessment.

Podiatric medicine had its own evolution in the medical field apart from allopathic and osteopathic medicine. Podiatrists are well-respected members of the health-care team and have earned recognition as physicians within their education, training, and credentialing processes. Unlike allopathic medical doctors and doctors of osteopathic medicine, whose scope of practice is based upon their education, training, and credentialing processes, podiatrists' scopes of practice are determined by state laws (and are often influenced by politics) with variances across the United States. In contrast to a lack of uniformity in the training and credentialing processes of an allopathic medical doctor, podiatrists complete a streamlined educational process that is competency-based and well-aligned from the undergraduate phase (podiatric medical school) to the postgraduate phase (residency) through the credentialing processes (licensure and certification). Podiatric medical students begin to directly engage in the specialty related to the diagnosis and treatment of the lower extremity much earlier in the educational process than an orthopedist, whose foot and ankle exposure is less extensive by comparison.

Developing the public health role of a front line clinical service: integrating stop smoking advice into routine podiatry services.

BACKGROUND: Although smoking is a major public health problem, many clinicians do not routinely provide evidence-based health improvement advice to smokers to help them to quit. METHODS: Plan, Do, Study, Act (PDSA) cycle methodology was used to design and implement a service development so that health improvement advice for smokers featured in all podiatry consultations provided by a Primary Care Trust in North East England. IT systems were developed to record the number and proportion of patients for whom smoking status was assessed, and the number and proportion of smokers who were given advice to quit and referred for specialist support. A questionnaire to staff explored their perceptions of the development on their clinics and consultations. RESULTS: During a 6-month period, smoking status was recorded for all 8831 (100%) patients attending podiatry clinics; 83% of smokers were given brief advice to quit; 7% of smokers were given help to access specialist stop smoking support services. Improvements were introduced within existing budgets and did not prolong clinics. CONCLUSIONS: It is straightforward and inexpensive to develop clinical services so that public health guidance is routinely implemented. More widespread implementation of similar service developments could lead to national improvements in public health.
