The impact of team based interprofessional comprehensive assessments on the diagnosis and management of diabetic foot ulcers: A retrospective cohort study

Treatment of Diabetic Foot Ulcers Based on an Interdisciplinary Team Approach: Exploratory Cross-Sectional Study of Patients' Views on Quality of Care

PURPOSE

The purpose of this study was to evaluate patients' perception and quality of diabetic foot ulcer (DFU) care delivered by an interdisciplinary team approach (ITA).

DESIGN

Exploratory cross-sectional study.

SUBJECTS AND SETTING

Twenty patients with a healed plantar DFU were recruited from an interdisciplinary Wound Care clinic of a Canadian University affiliated hospital. Their mean age was 64 years (75% were males [n = 15]), 18 (90%) were living with type 2 diabetes, and 45% (n = 9) had osteomyelitis in the previous year of their enrollment in the study.

METHODS

The validated short form of the Quality From the Patient's Perspective questionnaire was used to evaluate quality of care dimensions (medical-technical competence of the caregivers; physical-technical conditions of the care organization; degree of identity-orientation in the attitudes and actions of the caregivers; and sociocultural atmosphere of the care organization).

RESULTS

Respondents reported experiencing a high level of quality care with an ITA. All indicators of patient-perceived reality of care delivered were superior or equal related to their subjective importance in all dimensions of quality care (with scores ranging from 3.85 to 4.00 on a 4-Point Likert scale). Patients' satisfaction regarding the ITA was high.

CONCLUSIONS

Study findings suggest that an ITA model provided high quality of care for treating DFUs for all quality dimensions judged important for patients.

Short-term effect of dressing with Dermaheal ointment in the treatment of diabetic foot ulcer: A double-blinded randomized controlled clinical trial

Background and Aims

Diabetic foot ulcers, a major cause of amputations in diabetics, could benefit from natural products as adjuncts to standard care, given the costs and adverse effects of typical therapies. This study aims to evaluate the short-term effects of dressing with Dermaheal ointment in the treatment of DFUs through a double-blinded randomized controlled clinical trial.

Methods

This double-blinded, placebo-controlled trial included 50 patients with Wagner's ulcer grade I or II, randomly assigned to Dermaheal and placebo groups (received standard treatment and placebo ointment). The ulcer site was dressed daily for four consecutive weeks with either Dermaheal or placebo ointment. Ulcer healing score (using DFU healing checklist), ulcer size with transparent ruler and largest dimension of ulcer, and pain severity using numerical pain rating score (were recorded at five-time points, including baseline, and on weeks 1, 2, 3, and 4). Also, ulcer healing status was investigated at the trial ended in November 2021.

Results

Both groups showed significant improvement in ulcer healing over 4 weeks (p time < 0.001), with more remarkable progress in the Dermaheal group (p group = 0.03). At the trial end, complete ulcer healing was also significantly higher in the Dermaheal group compared to the placebo group (56% vs. 12%, p = 0.002). Both groups exhibited a decrease in ulcer size (p time < 0.001). Considering the baseline ulcer size as a covariate, substantial changes in mean ulcer size were noted in the initial (p = 0.01), second (p = 0.001), third (p = 0.002), and fourth (p = 0.002) weeks of the intervention, showing a preference for the Dermaheal group. However, no significant between-group difference was observed in pain severity levels.

Conclusion

Dressing with Dermaheal as a topical treatment shows promise in improving healing and reducing the size of diabetic foot ulcers. Further research is needed to confirm these findings' long-term efficacy.

What Patients Think: A Study Examining Perceptions of Teamwork, Self-Management, and Quality of Life of Patients Diagnosed With Diabetic Foot Ulceration

Identifying strategies to support patients diagnosed with diabetic foot ulceration (DFU) is essential to affect not only wound outcomes but also mortality and quality of life. This article reports on a cross-sectional, descriptive, correlational study of patients receiving treatment for DFU at a specialty clinic. Most participants were <60 years of age and had been diagnosed with diabetes for >5 years. Results indicated that patients with higher self-management scores reported improved general health, physical functioning, and quality of life. These findings, in a younger patient population with normal work and family obligations, suggest that interventions supporting self-management behaviors can improve physical, emotional, and general health and, ultimately, quality of life. The involvement of an interprofessional care team enhances these self-management behaviors.

A Patient Navigation Model to Improve Complex Wound Care Outcomes

OBJECTIVE

To create a blended format model to navigate interprofessional team assessments of patients with complex wounds during COVID-19 as a quality improvement process.

METHODS

During clinical assessments, patients were interviewed in their homes with representation from their circle of care and primary nurse on site linked to a live virtual interprofessional blended remote team model (wound care nurse specialist, advanced wound care doctor). Eligible patients had completed a wound care clinical pathway without wound closure. Palliative patients with complex wounds and patients without precise/accurate diagnoses were also included. This process addressed the components of Wound Bed Preparation 2021: manage the cause, address patient-centered concerns, determine the ability to heal, optimize local wound care, and evaluate outcomes on an ongoing basis.

RESULTS

Since April 2020, 48 patients were referred to the Home and Community Care Support Services patient navigation interprofessional team. Patients' home-care services were initiated between 2012 and 2021. The team provided closure in 29% of patients and the wound surface area reduced in 66%. Pain was reduced in 73% of patients and appropriate infection management was implemented in 79%. In addition, nursing visits were reduced by 73% and there was a 77% decrease in supply usage.

CONCLUSIONS

This project validated the Wound Bed Preparation Paradigm 2021 as a process for assessing patients with complex wounds using a blended virtual and home-based assessment. Patient navigation with this blended model benefited patients and improved healthcare system utilization with projected cost savings.

Diabetic leg and foot ulcers: how district nurses can promote wound healing through blood glucose control

Diabetes is a chronic and often life-long condition that is a consequence of the blood glucose level being too high (National Institute for Health and Clinical Excellence (NICE), 2019). Diabetes covers a range of conditions such as type 1 diabetes, type 2 diabetes and gestational diabetes. It has been well documented that uncontrolled blood glucose levels can lead to further circulatory damage, which impedes the wound healing process and often results in chronic wounds that do not heal. This article uses data collected from an audit and explores how district nursing teams can improve wound healing for those living at home with diabetic ulcers (DUs) by regularly monitoring blood glucose levels. This is followed by a discussion on how district nurses can support their team to adapt best practice, and the benefits of regularly checking blood glucose levels, even for service users that manage their diabetes with diet or oral medication. The article also explores how the multidisciplinary team can be accessed and used efficiently and how leadership skills can improve service user care and safety.

Early ABI Testing May Decrease Risk of Amputation for Patients With Lower Extremity Ulcers

BACKGROUND

Patients with lower extremity wounds from diabetes mellitus or peripheral artery disease (PAD) have a risk of amputation as high as 25%. In patients with arterial disease, revascularization decreases the risk of amputation. We aimed to determine if the early assessment of arterial perfusion correlates with the risk of amputation.

METHODS

We retrospectively reviewed patients referred to the vascular clinic over 18 months with Rutherford Grade 5 and 6 chronic limb-threatening ischemia to determine if patients had a pulse exam done at the time the wound was identified and when ankle brachial index (ABI) testing to evaluate perfusion was performed. Kaplan Meier analysis was used to determine if the timing of ABI testing affected the time to revascularization, wound healing, and risk of amputation.

RESULTS

Ninety-three patients with lower extremity wounds were identified. Of these, 59 patients (63%) did not have a pulse exam performed by their primary care provider when the wound was identified. Patients were classified by when they underwent ankle brachial index testing to assess arterial perfusion. Twenty-four had early ABI (<30 days) testing, with the remaining 69 patients having late ABI testing. Patients in the early ABI group were more likely to have a pulse exam done by their PCP than those in the late group, 12 (50%) vs. 22 (32%), P = 0.03. Early ABI patients had a quicker time to vascular referral (13 days vs. 91 days, P < 0.001). Early ABI patients also had quicker times to wound healing than those in the late group (117 days vs. 287 days, P < 0.001). Finally, patients that underwent early ABI were less likely to require amputation (Fig. 1), although this did not reach statistical significance (P = 0.07).

CONCLUSIONS

Early ABI testing expedites specialty referral and time to revascularization. It can decrease the time to wound healing. Larger cohort studies are needed to determine the overall effect of early ABI testing to decrease amputation rates.

Outcomes and prognosis of diabetic foot ulcers treated by an interdisciplinary team in Canada

The aim of this study was to determine the wound healing outcomes of patients with a plantar diabetic foot ulcer (DFU) treated with an interdisciplinary team approach, and to identify associated variables. A retrospective observational cohort study of 140 adult patients, with a plantar DFU, treated between 2012 and 2018 at a wound care clinic of a University affiliated hospital was conducted. Predictive and explicative analyses were conducted with logistic multivariate methods and with a Receiver Operating Characteristics curve. The best predictor of wound healing at 3 months was a 41.8% wound size reduction at 4 weeks (AUC: 0.86; sensitivity: 83.1%; specificity: 67.2%, positive predictive value: 72.8%; negative predictive value: 78.9%; positive and negative likelihood ratios: 2.53 and 0.25, respectively). Main baseline variables independently associated with this predictor were: a monophasic Doppler waveform (OR 7.52, 95% CI [2.64–21.39]), cigarette smoking (OR 4.7, 95% CI [1.44–15.29]), and male gender (OR 3.58, 95% CI [1.30–9.87]). The health care provider should be cautious and intensify its management of DFUs particularly with patients of male gender; smoking, having a monophasic waveform with a hand‐held Doppler, and not achieving a minimal 41.8% wound area reduction at 4 weeks of treatment.

Quality of Diabetic Foot Ulcer Care: Evaluation of an Interdisciplinary Wound Care Clinic Using an Extended Donabedian Model Based on a Retrospective Cohort Study

OBJECTIVES

Diabetic foot ulcer (DFU), a serious complication of diabetes, is associated with increased morbidity and mortality and presents a substantial socioeconomic burden. However, DFU quality of care has been insufficiently studied. Therefore, the aim of this study was to evaluate the quality of DFU care at an interdisciplinary wound care clinic in Canada, based on an extended Donabedian model: structure, process and outcome quality indicators combined with patient characteristics.

METHODS

This was a retrospective cohort study of 140 adult patients with diabetes who were treated between 2012 and 2018 at a wound care clinic in a university-affiliated hospital in the Québec City area of Canada. Twenty-two internationally recognized quality-of-care indicators were identified from the literature. Data were collected from medical files, and the results were used to document the selected quality-of-care indicators.

RESULTS

The principal indicators regarding structure and process were met, and outcome indicators were influenced by study population characteristics, particularly peripheral artery disease and critical limb ischemia. Moreover, this study highlights that quality-of-care indicators are essential when evaluating DFU outcomes, as structure and process indicators can also affect wound healing outcomes.

CONCLUSIONS

This study suggests that DFU care at a Canadian wound care clinic, with an interdisciplinary approach, meets most quality-of-care indicators. The socioeconomic burden of DFUs for patients, health-care organizations and policymakers, and the paucity of quality and performance evaluations, call for more studies evaluating DFU care.

Regional health care services and rates of lower extremity amputation related to diabetes and peripheral artery disease: an ecological study

BACKGROUND

The care necessary to prevent amputation from diabetes and peripheral artery disease (PAD) remains disjointed in many jurisdictions. To help inform integrated regional care, this study explores the correlation between regional health care services and rates of lower extremity amputation.

METHODS

This ecological study included 14 administrative health regions in Ontario, Canada. All diabetes- or PAD-related major (above ankle) amputations (Apr. 1, 2007, to Mar. 31, 2017) were identified among residents 40 years of age and older. For each region, age-and sex-adjusted amputation rates were calculated as well as per capita counts of key health providers (podiatrists and chiropodists, as well as surgeons) and health care utilization among study patients in the year before the first major amputation (physician visits, publicly funded podiatry visits, emergency department visits, hospital admissions, home care nursing, minor amputation, limb revascularization).

RESULTS

A total of 11 658 patients with major amputation were identified (of whom 79.2% had diabetes and 96.5% had PAD). There was wide regional variation in amputation rates: 2.53 to 11.77 per 100 000 person-quarters. At a regional level, the proportion of study patients who received revascularization showed the strongest negative correlation with amputation rates. The regional proportion of study patients who saw a vascular surgeon showed the strongest negative correlation with amputation rates, relative to other health provider visits. Other measures of health care utilization among patients correlated poorly with regional amputation rates, as did the regional provider counts. The results were similar when we restricted the analysis to diabetes-related amputations.

INTERPRETATION

Amputation rates related to diabetes and PAD vary widely across Ontario. Access to vascular assessment and revascularization must be integrated into regional amputation prevention efforts.

Development and evaluation of an interprofessional teaching concept for modern wound management

BACKGROUND AND OBJECTIVES

The aim of the present study was to establish and evaluate a new interprofessional teaching concept on the topic of wound management.

METHODS

After determining the status quo using a survey among medical students, we developed a new teaching concept that included a 150-minute course aimed at providing students with the opportunity to gain hands-on wound management skills. This interprofessional course was offered at the existing 'SkillsLab' teaching facility. The participants' subjective level of knowledge was assessed by questionnaire before and after the course.

RESULTS

Our survey among 190 medical students showed them to be very interested in gaining practical experience in the field of wound management. To date, 120 participants (54.8 % medical students; 45.2 % nursing students) have attended this new interprofessional course, which has been equally well received by both medical and nursing students. For all specific topics (diagnosis, treatment, use of wound dressings, debridement), course participation was associated with a significant increase in knowledge.

CONCLUSION

Given its relevance in clinical practice, it is important for medical students to learn about the various aspects associated with the care of patients with chronic wounds. By offering new teaching concepts, dermatology in particular is well suited to help students gain a better understanding of the challenges related to wound management and to improve their practical skills. Wound management is an ideal topic for interprofessional learning.

Guidelines on multidisciplinary approaches for the prevention and management of diabetic foot disease (2020 edition)

In recent years, as living standards have continued to improve, the number of diabetes patients in China, along with the incidence of complications associated with the disease, has been increasing. Among these complications, diabetic foot disease is one of the main causes of disability and death in diabetic patients. Due to the differences in economy, culture, religion and level of medical care available across different regions, preventive and treatment methods and curative results for diabetic foot vary greatly. In multidisciplinary models built around diabetic foot, the timely assessment and diagnosis of wounds and appropriate methods of prevention and treatment with internal and external surgery are key to clinical practice for this pathology. In 2019, under the leadership of the Jiangsu Medical Association and Chinese Diabetes Society, the writing group for the Guidelines on multidisciplinary approaches for the prevention and management of diabetic foot disease (2020 edition) was established with the participation of scholars from the specialist areas of endocrinology, burn injury, vascular surgery, orthopedics, foot and ankle surgery and cardiology. Drawing lessons from diabetic foot guidelines from other countries, this guide analyses clinical practices for diabetic foot, queries the theoretical basis and grades and gives recommendations based on the characteristics of the pathology in China. This paper begins with assessments and diagnoses of diabetic foot, then describes treatments for diabetic foot in detail, and ends with protections for high-risk feet and the prevention of ulcers. This manuscript covers the disciplines of internal medicine, surgical, nursing and rehabilitation and describes a total of 50 recommendations that we hope will provide procedures and protocols for clinicians dealing with diabetic foot.

Effects of Hydrogel With Enriched Sodium Alginate in Wounds of Diabetic Patients

Objective of this study was to evaluate the efficacy of the autolytic debridement promoted by hydrogel with sodium alginate enriched with fatty acids and vitamins A and E in the healing of foot wounds in diabetic patients. A clinical study was conducted at an outpatient clinic of medical specialties. The sample comprised 8 patients supervised for a 3-month period, from April to July 2017, by means of a clinical history, photographic record, planimetry, and classification of the wound severity by the Pressure Ulcer Scale for Healing (PUSH) system. Of the 8 patients supervised, 1 dropped out and 7 were followed up for 12 weeks. Only 2 had complete wound healing, but all presented a reduction of the lesion area of approximately 22.2% and PUSH score of 9.8 to 6.6. This study found that hydrogel showed good results for the treatment of diabetic feet, reducing the area and overall PUSH score of the wounds.

Advancements in improving health-related quality of life in patients living with diabetic foot ulcers

INTRODUCTION

Diabetic foot ulcer (DFU) constitutes a burden to patients with diabetes deteriorating their quality of life. Health related quality of life (HRQoL) can now be quantified with the use of specific tools; some of them provide a holistic approach to patients' well-being, while others are disease specific or even region specific. Many of these tools are applicable to patients with DFU. This review will present current data about the impact different interventions in the management of DFU on quality of life related parameters.

AREAS COVERED

We performed a search of literature using keywords 'diabetes mellitus', 'diabetic foot ulcer', 'diabetic foot', 'health related quality of life', 'quality of life' and 'SF-36' to identify studies that contained data about the relationship between different interventions and quality of life of patients with diabetic foot ulcers.

EXPERT COMMENTARY

Available data are not sufficient to conclude on the impact of interventions aimed to heal DFU on HRQoL. There is need for more, better designed studies and meta-analysis to estimate the effect of treatments on HRQoL in patients with DFUs. The development of new, diabetic foot specific tools will help to improve our knowledge in this field.
