Evaluating the impact of an interdisciplinary integrated limb preservation service operating concurrently with a single-specialty service.

BACKGROUND: This study examined the efficacy of an interdisciplinary limb preservation service (LPS) in improving surgical outcomes for diabetic foot ulcer (DFU) patients compared to traditional care. METHODS: Data from January 1, 2017 to September 30, 2020 were retrospectively reviewed. An interdisciplinary LPS clinic began on August 1, 2018, coexisting with a preexisting single specialty service. Primary outcomes were major/minor amputation rates and ratios and hospital length of stay. Surgical endpoints pre- and post-LPS launch were compared. RESULTS: Among 976 procedures for 731 unique DFU patients, most were male (80.4%) and Hispanic (89.3%). Patient demographics were consistent before and after LPS initiation. Major amputation rates decreased by 45.5% (15.4%-8.4%, p = 0.001), with outpatient procedures increasing over 5-fold (3.3% pre-LPS to 18.7% post-LPS, p < 0.001). Hospital stay reduced from 10.1 to 8.5 days post-LPS (p < 0.001). The major to minor amputation ratio declined from 22.4% to 12.7%. CONCLUSIONS: The interdisciplinary LPS improved patient outcomes, marked by fewer major amputations and reduced hospital stays, suggesting the model's potential for broader application.

A Novel Technique to Close Large Defects in the Foot Secondary to Infection Using Widely Available and Inexpensive Tools: A Case Report.

One of the challenges after central ray resection is a large soft-tissue defect. Many authors have reported the use of external fixators as a means of narrowing the forefoot. Ours is the first article to report an interesting case using widely available and inexpensive tools such as Kirschner and cerclage wires as an external fixation means of narrowing the forefoot after a complete second-ray resection and extensive soft-tissue debridement for a severe diabetic foot ulcer. This simple yet inexpensive technique is easy to perform for any foot and ankle surgeon at any hospital or surgical center.

Dosing Activity and Return to Preulcer Function in Diabetes-Related Foot Ulcer Remission.

Diabetes-related foot ulcers are a leading cause of global morbidity, mortality, and health-care costs. People with a history of foot ulcers have a diminished quality of life attributed to limited walking and mobility. One of the largest concerns is ulceration recurrence. Approximately 40% of patients with ulcerations will have a recurrent ulcer in the year after healing, and most occur in the first 3 months after wound healing. Hence, this period after ulceration is called "remission" due to this risk of reulceration. Promoting and fostering mobility is an integral part of everyday life and is important for maintaining good physical health and health-related quality of life for all people living with diabetes. In this short perspective, we provide recommendations on how to safely increase walking activity and facilitate appropriate off-loading and monitoring in people with a recently healed foot ulcer, foot reconstruction, or partial foot amputation. Interventions include monitored activity training, dosed out in steadily increasing increments and coupled with daily skin temperature monitoring, which can identify dangerous "hotspots" prone to recurrence. By understanding areas at risk, patients are empowered to maximize ulcer-free days and to enable an improved quality of life. This perspective outlines a unified strategy to treat patients in the remission period after ulceration and aims to provide clinicians with appropriate patient recommendations based on best available evidence and expert opinion to educate their patients to ensure a safe transition to footwear and return to activity.

Functional ambulatory status as a potential adjunctive decision-making tool following wound, level of ischemia, and severity of foot infection assessment.

The Society for Vascular Surgery Lower Extremity Threatened Limb Classification System has been developed to stratify amputation risk on the basis of extent of the wound, level of ischemia, and severity of foot infection (WIfI). However, there are no currently validated metrics to assess, grade, and consider functional status, especially ambulatory status, as a major consideration during limb salvage efforts. Therefore, we propose an adjunct to the current WIfI system to include the patient's ambulatory functional status after initial assessment of limb threat. We propose a functional ambulatory score divided into grade 0, ambulation outside the home with or without an assistive device; grade 1, ambulation within the home with or without an assistive device; grade 2, minimal ambulation, limbs used for transfers; and grade 3, a person who is bed-bound. Adding ambulatory function as a supplementary assessment tool can guide clinical decision making to achieve optimal future functional ambulatory outcome, a patient-centered goal as critical as limb preservation. This adjunct may aid limb preservation teams in rapid, effective communication and clinical decision making after initial WIfI assessment. It may also improve efforts toward patient-centered care and functional ambulatory outcome as a primary objective. We suggest a score of functional ambulatory status should be included in future trials of patients with chronic limb-threatening ischemia.

Building a scalable diabetic limb preservation program: four steps to success.

Over the past generation, limb preservation programs and diabetic foot services have begun to proliferate within academic health science centers as well as within health-care systems in general. We describe four key components for a successful program that, developed sequentially with temporal overlap, can allow the program to scale. The first component includes establishment of a 'hot foot line' for urgent emergency department/inpatient referral. The second includes development of a wound-healing clinic to address outpatient care through to remission. The third component focuses on the diabetic foot in remission to maximize ulcer-free days following healing. The fourth and final component focuses on implementation of local and widespread screening clinics to identify and triage patients into appropriate therapeutic and surveillance programs for healing, remission, and primary prevention. Along with developing each of these components, we describe discrete methods to quantify success.
