Thoughts and experiences regarding leg amputation among patients with diabetic foot ulcers: A phenomenological study

Despite lower-limb amputation being common among patients with diabetic foot ulcers, few studies have qualitatively investigated the patients' perspectives. Therefore, this study aimed to explore the thoughts and experiences of patients with diabetic foot ulcers regarding lower-limb amputation in Hong Kong. A phenomenological study using individual, semi-structured interviews was conducted with 18 participants with foot ulcers recruited in Hong Kong between July and September 2022. The interviews were audio-recorded, transcribed verbatim, and analysed using an interpretative phenomenological approach and a constant comparison strategy. The results highlighted four substantial themes: (a) coping or being alone and taciturn, (b) altered appearance impacting one's sense of maintaining social relations, (c) thoughts about self-efficacy and encountering a new normal, and (d) the possibility of a reduced gap in physical consequences between the old and new self. This study provided different perspectives of patients with a history of diabetic foot ulcers, even in cases where lower-limb amputation has not yet been performed. The results demonstrate that lower-limb amputation is considered a forbidden topic. This makes it culturally difficult for Chinese patients to discuss the matter with healthcare authorities and family members. Healthcare workers should be aware of how they communicate regarding lower-limb amputation.     

Factors associated with lower‐extremity amputation in patients with diabetic foot ulcers in a Chinese tertiary care hospital

Providing a better understanding of the risk factors for amputation in this particular region, Hunan province, in China might help patients with diabetic foot ulcers receive timely and appropriate medical care and help prevent amputation. Diabetic foot ulcer patients referred to the Third Xiangya Hospital during the period between December 2014 and September 2018 were enrolled. Participants who underwent amputations and received conservative treatments were compared using univariate and multivariate analyses to identify the independent predictors of amputation. Those who required amputation presented significantly higher levels of white blood cell counts, platelet counts, erythrocyte sedimentation rate, C‐reactive protein, and glycated haemoglobin (HbA1c) levels. However, levels of haemoglobin, postprandial plasma C‐peptide, triglyceride, high‐density lipoprotein cholesterol, albumin, and uric acid were decreased in patients with amputations. Patients with more advanced Wagner grades had much higher rates of amputation. Multivariable‐adjusted odds ratios in stepwise logistic regression model was 1.317 for HbA1c (95% CI: 1.015‐1.709), 0.255 for triglyceride (95% CI: 0.067‐0.975), and 20.947 for Wagner grades (95% CI: 4.216‐104.080). Independent risk factors for amputation in these Chinese diabetic foot ulcer patients included an elevated HbA1c level, lower triglyceride level, and higher Wagner grades.     

Status and influencing factors of lower limb amputation in patients with diabetic foot ulcer

To investigate the influencing factors of lower limb amputation in patients with diabetic foot ulcers. Patients with diabetic foot ulcers who were hospitalised in a tertiary general hospital in Guizhou Province from January 2019 to March 2022 were retrospectively collected. Sociological information of the general population, comorbidities, laboratory-related indicators, and information on the specialty situation, using univariate analysis and multifactor analysis, compared the influencing factors of amputation and non-amputee patients. A total of 205 patients with diabetic foot and 69 ampute patients (33.7%) were enrolled. The univariate analysis found that the decrease in HDL cholesterol levels was associated with the occurrence of lower extremity amputation, and logistic stepwise regression analysis showed that HDL-C was inversely correlated with the amputation rate of patients with diabetic foot ulcers, and the risk of amputation at low levels of HDL-C was 2.452 times higher than that of high-level HDL-C (95% CI: 1.105–5.846). Decreased HDL cholesterol levels are an independent predictor of amputation in patients with diabetic foot ulcers.     

Impact of multidisciplinary foot care team on outcome of diabetic foot ulcer in term of lower extremity amputation at a tertiary care unit in Karachi,Pakistan

To compare the outcomes of diabetic foot ulcers (DFU) in terms of healing and lower extremity amputation (LEA) rate before and after training of multidisciplinary foot care team (MDFCT). Subjects were categorised into two groups; Group‐A cases seen between 1997 and 2006 (before upgrading of training and services of MDFCT) and Group‐B cases seen between 2007 and 2016 (after upgrading of training and services of MDFCT). Baseline demographic characteristics, biochemical results, and outcomes of DFU in terms of healing or amputation were analysed by using statistical package social science (SPSS) version 20. Total 7994 DFU cases seen, 888 in group A and 7106 in group B. Mean age of patients was 53.80 ± 10.40 years and mean haemoglobin (HbA1c) was 10.12 ± 2.44. Overall, decreasing trends of amputations were observed from baseline 27.5% to 3.92% during the period of 20 years. In group A, 479 (78.8%) subjects healed completely compared with 3806 (89.1%) in group B. Significant reduction in toe amputations ([13.81%] vs [8.11%]) and below knee amputations [(5.26%) vs (1.82%)] were seen. Similarly, rates of above knee amputation ([1.80%] vs [0.35%] P‐value 0.008) in two groups was also significant. Significant improvement was observed in outcomes of DFU in terms of amputation through multidisciplinary team approach.     

Knowledge and practice of diabetic foot care and the prevalence of diabetic foot ulcers among diabetic patients of selected hospitals in the Volta Region,Ghana

Diabetic foot ulcers (DFUs) are a common but serious complication of diabetes mellitus (DM). The factors distressing the worth of diabetic foot care (DFC) are knowledge and practice. Foot ulcers are the main cause of amputation and death in people suffering from DM. This study assessed the knowledge and practice of DFC and the prevalence of DFUs and its associated factors among diabetic patients of selected hospitals in the Volta Region, Ghana. A multihospital‐based cross‐sectional study was conducted among 473 patients with DM who were recruited using the systematic sampling method. Data were collected using a validated, pretested, and structured questionnaire, while medical variables were obtained from patient folders and analysed using SPSS version 23. All statistically significant parameters in bivariate analysis were incorporated in the multivariate logistic regression analysis. The results showed that 63% of diabetic patients had good knowledge of DFC, while 49% competently practiced it. A negative correlation was found between knowledge and practice levels of DFC (r = −0.15, P = <.01). The prevalence of DFUs was 8.7% among the studied diabetic patients. Male diabetic patients were 3.4 times more likely to develop DFUs than female diabetic patients (crude odd ratio [cOR] = 3.35; 95% confidence interval [CI] = 1.75‐6.43; P = <.001). Type 1 diabetic patients were five times more likely to develop DFUs than those who had type 2 diabetes (cOR = 5.00; 95% CI = 2.50‐10.00; P = <.001). Diabetic patients who had a family history of diabetes were 4.7 times more likely to develop DFUs than those without family history (adjusted odd ratio [aOR] = 4.66; 95% CI = 1.55‐13.89; P = .006). Those who had diabetes for 5 to 10 years were 3.3 times more likely to develop DFUs than those who had diabetes for less than 5 years (aOR = 3.28; 95% CI = 1.40‐7.67; P = .006). Diabetic patients who had comorbidity were 3.4 times more likely to develop DFUs than those without comorbidity (cOR = 3.35; 95% CI = 1.74‐6.45; P = <.001). The study found that there was good knowledge but poor practices of DFC among patients. Health care providers are expected to better educate patients and emphasise self‐care practices to patients. Health care providers should also give more attention to patients with associated risk factors to avoid further complications and reduce the occurrence of DFUs.

Risk factors that predict major amputations and amputation time intervals for hospitalised diabetic patients with foot complications

Diabetes‐related lower extremity amputations are an enormous burden on global health care and social resources because of the rapid worldwide growth of the diabetic population. This research aimed to determine risk factors that predict major amputation and analyse the time interval from first hospitalisation to amputation by using standard management protocols and Kaplan–Meier survival curves. Data from 246 patients with diabetes mellitus and diabetic foot ulcers from the Division of Plastic and Reconstructive Surgery of the Department of Surgery at XXX Hospital between January 2016 and May 2020 were analysed. Univariate and multivariate analyses of 44 potential risk factors, including invasive ulcer depth and C‐reactive protein levels, showed statistically significant differences for those at increased risk for major amputation. The median time from hospitalisation to lower extremity amputation was approximately 35 days. Most patients with abnormal C‐reactive protein levels and approximately 70% of patients with ulcers invading the bone were at risk for lower extremity amputations within 35 days. Therefore, invasive ulcer depth and C‐reactive protein levels are significant risk factors. Other potential risk factors for major amputation and the time intervals from first hospitalisation to amputation should be analysed to establish further prediction strategies.     

Timing of minor and major amputation in patients with diabetes-related foot ulceration admitted to two public tertiary referral hospitals in Australia

Background

There is limited information regarding the number of patients with diabetes-related foot ulceration (DFU) who receive minor or major amputation, and how quickly these amputations occur. This study aimed to identify the incidence of index minor and major amputation among inpatients with DFU over 4 years, and where amputation occurred during the patient's index DFU-related admission, investigate prognostic factors.

Methods

The incidence of index minor and major amputation, and the admission sequence during which amputation occurred were identified from DFU-related admissions to two public hospitals during 2014–2018. Where minor or major amputation occurred during the patient's index DFU-related admission, prognostic factors were investigated using logistic regression.

Results

DFU-related hospital admissions were required by 564 patients. The incidence of minor amputation over 4 years was 34% (n = 193). The incidence of minor amputation during the patient's index DFU-related admission was 28% (n = 155), which was associated with requiring revascularisation (odds ratio [OR] 2.33, 95% CI 1.53–3.55, P < 0.001). The incidence of major amputation over 4 years was 8% (n = 45). The incidence of major amputation during the patient's index DFU-related admission was 6% (n = 31), which was associated with having more comorbidities (OR 1.58, 95% CI 1.10–2.26, P = 0.01) and receiving care for a mental health condition (OR 3.85, 95% CI 1.48–10.01, P = 0.006).

Conclusion

Most amputations occurred during the patient's index DFU-related hospital admission. Major amputation during a patient's index admission was associated with more comorbidities and mental health conditions.     

Evaluation of diabetic foot care knowledge,determinants of self-care practices and the efficacy of health education

To evaluate the risk factors connected with diabetic foot care and investigate the impact of health education on promoting proper diabetic foot care practices. An explanatory and mixed-method study was performed. We administered a structured pretest questionnaire to patients diagnosed with Type 2 diabetes who frequented our health examination center and community health clinics. The survey encompassed patient demographics, basic knowledge concerning diabetic foot care, and self-care practices pertaining to diabetic foot care. Concurrent assessments and scoring were carried out. Following the survey, patients underwent health education sessions focusing on foot self-care behaviours. Their progress was reevaluated after 2 weeks to gauge its effectiveness. We identified educational attainment, diabetes duration, regular follow-up, and blood sugar control as critical factors influencing knowledge about foot care and self-care practices related to it. Pearson correlation analysis demonstrated a positive relationship between scores for diabetic foot care knowledge and scores for self-care behaviours (r = 0.32, p < 0.001). Health education led to a significant improvement in the self-care behaviours of diabetic patients. A variety of factors affect the occurrence of diabetic foot complications and the self-care behaviours associated with diabetic foot care. Health education proves to be an effective means of enhancing diabetic foot care behaviours.     

Association of diabetic foot care and amputation rates in Germany

Podologists are nurses who care for the diabetic foot (orthotics, offloading devices, blisters, calluses, treatment of fungus infection and patient education). In contrast to podiatrists, they are not qualified to perform any surgical treatment or wound care. We analysed whether there is an association between the decrease in major amputations and the number of podologic foot care (PFC) visits prescribed in Germany. Detailed list of all major lower limb amputations (OPS 5‐864) performed from 2007 to 2011 was provided by the Federal Statistical Office. Data were separated for the 16 federal states in Germany. Detailed lists of the number of PFC treatments for each of the 5 years were derived from the federal report of the statutory health insurance. The total numbers of hospitalised cases per year having diabetes mellitus documented as an additional diagnosis were used to adjust for the different rates of people with diabetes in each federal state. Within a 5‐year time period, population‐based major amputations per 100 000 people dropped from 21·7 in 2007 to 17·5 in 2011 (?18·5%); whereas the number of PFC treatments per 1000 insured increased from 22 in 2007 to 60 in 2011 (+172·7%). The total number of major amputations divided by the total number of hospitalised cases with the additional diagnosis of diabetes mellitus (DM) shows an inverse correlation with the number of PFC treatments per 1000 insured (Pearson's correlation factor is ?0·52049). The five countries with the highest increase in PFC compared with the five countries with the lowest increase (35·6 versus 15·4 per 1000 insured) will have only small differences in the decrease in major amputation rates in this period (?5·1 versus ?3·4 per 100.000). There is a strong association between increasing utilisation PFC and decreasing major amputations in Germany. Further study is required to document the cost‐effectiveness of this service.     

An explainable machine learning model for predicting in‐hospital amputation rate of patients with diabetic foot ulcer

Diabetic foot ulcer (DFU) is one of the most serious and alarming diabetic complications, which often leads to high amputation rates in diabetic patients. Machine learning is a part of the field of artificial intelligence, which can automatically learn models from data and better inform clinical decision‐making. We aimed to develop an accurate and explainable prediction model to estimate the risk of in‐hospital amputation in patients with DFU. A total of 618 hospitalised patients with DFU were included in this study. The patients were divided into non‐amputation, minor amputation or major amputation group. Light Gradient Boosting Machine (LightGBM) and 5‐fold cross‐validation tools were used to construct a multi‐class classification model to predict the three outcomes of interest. In addition, we used the SHapley Additive exPlanations (SHAP) algorithm to interpret the predictions of the model. Our area under the receiver‐operating‐characteristic curve (AUC) demonstrated a 0.90, 0.85 and 0.86 predictive ability for non‐amputation, minor amputation and major amputation outcomes, respectively. Taken together, our data demonstrated that the developed explainable machine learning model provided accurate estimates of the amputation rate in patients with DFU during hospitalisation. Besides, the model could inform individualised analyses of the patients'' risk factors.     

The impact of Syme amputation in surgical treatment of patients with diabetic foot syndrome and Charcot-neuro-osteoarthropathy

Introduction Charcot-neuro-osteoarthropathy with its severe destruction of bones remains a challenge for physicians and surgeons. The aim of the study was to characterise a patient population treated in a specialised foot care centre who underwent surgical treatment for their diabetic foot syndrome. Special attention was paid to patients who suffered from Charcot-neuro-osteoarthropathy and the impact of Syme amputation if amputation of the foot was inevitable.Materials and methods A total of 121 patients with diabetic foot syndrome and ulcerations underwent an interdisciplinary strategy for diagnostic and therapeutic procedures including MRI and surgical interventions. If peripheral arterial vessel disease was present, revascularisation by distal bypass grafting was done before the orthopaedic intervention. Some 24% showed the typical neuro-osteoarthropathy with severe bone destruction. In 8 cases amputation of the foot was performed using the Syme technique.Results In our population the short-term results (follow-up 12 months, 20% lost to follow-up) are good, only 4% of the patients required further surgery on the same foot. In all patients with Charcot feet, plain radiographs showed the typical radiographic signs of the disease, and MRI was most helpful to detect abscess formations. The typical clinical problems of patients with Charcot disease are pointed out, and conservative and surgical treatment options are discussed. All patients with Syme amputation did well, wound healing and weight-bearing of the limb were accomplished.Conclusion The crucial diagnostic tool for decision-making in diabetic foot syndrome was MRI, which normally shows osteomyelitis with high sensitivity and specificity. In patients with Charcot-neuro-osteoarthropathy, the bone marrow oedema of the involved parts of the skeleton might misleadingly suggest the diagnosis of osteomyelitis. If amputation is inevitable in severe abscess formation combined with instability and perforation of the dislocated and destroyed bones in Charcot-neuro-osteoarthropathy, these patients might benefit from a foot amputation according to the technique Syme described. For this procedure the blood supply of the posterior tibial artery is essential. All these patients were able to walk without support. The material presented helps to generate hypotheses for further prospective studies.     

Analysis of routine blood markers for predicting amputation/re‐amputation risk in diabetic foot

Diabetic foot is challenging progressive disease which requires multisystemic control. Neuropathy, arteriopathy, and cellular responses should treated collaboratively. Despite all medical advances, diabetic foot can highly resulted with amputation and also re‐amputation can be required because of failed wound healing. In this study, we aimed to investigate the relation between blood parameters and amputation events. Diabetic 323 patients include to the study who referred to orthopaedic clinic for amputation. Amputation levels (amputation levels phalanx, metatarsal, lisfranc, syme, below knee, knee‐disarticulation, above‐knee amputation) and re‐amputations recorded and compared with routine blood parameters. Re‐amputation was observed at 69 patients. The significant difference detected between lower albumin, higher HbA1c, higher CRP levels (P < 0.05) in regards to gross amputation levels, and increased wound depth. Furthermore, lower albumin levels and higher levels of WBC, HbA1c, CRP, and Creatinine were detected in re‐amputation levels. Especially, HbA1c, CRP, and Creatinine levels were found as upper bound of reference line for re‐amputation. The statistically optimal HbA1c cutoff point for diabetes was ≥7.05%, with a sensitivity of 86% and a specificity of 59%. In according to our results, simple blood parameters can be useful for observing the progress of amputation in diabetic foot. Particularly, lower albumin, and higher HbA1c, CRP, and Creatinine levels detected as related with poor prognosis. Besides, screening of HbA1c level seems to be highly sensitive for detecting of re‐amputation possibility.     

Prediction of diabetic foot amputation using newly revised DIRECT coding system: Comparison of accuracy with that of five existing classification systems

Diabetes mellitus (DM) causes various complications over time, one such complication is diabetic foot ulcers (DFU), which are challenging to treat and can lead to amputation. Additionally, a system for accurate prediction of amputation has yet to be developed. In total, 131 patients were included in the study after retrospectively collecting data from 2016 to 2020 about DFU. The collected data were used for comparison of the accuracy between five existing classification systems and the newly revised DIRECT coding system, and investigation of risk factors for lower extremity amputation (LEA). The existing five classification systems and DIRECT system can effectively predict LEA. The DIRECT3 system has three elements, C-reactive protein (CRP), ulcer history (UH), and hypertension (HTN) in addition to those of the DIRECT system. It had a high predictive value and accuracy similar to that of Wagner and University of Texas (UT) on depth among the five classification systems. Among the statistically significant risk factors, duration of DM and HTN, haemoglobin (Hb), CRP, and UH showed an association with LEA. The DIRECT coding system is effective for predicting LEA and explaining appropriate treatment methods for DFU, and is widely applicable because of its user accessibility and convenience.     

Effect of lower extremity amputation on caregiving burden in caregivers of patients with diabetic foot: Prospective cohort study

Lower extremity amputation as a treatment of diabetic foot ulcer is probably a major burden for the patient's family and friends, who typically act as caregivers and support the patient in coping with the physical disabilities and emotional distress. In the present prospective study, we investigated the effects of different lower extremity amputation levels for diabetic foot ulcer treatment on caregivers of patients with diabetes using the Zarit Burden Interview (ZBI‐12) scale. Patients with diabetic foot ulcers who underwent unilateral major amputation (above‐below knee) and minor amputation of foot (heel sparing) and their caregivers were requested to volunteer to participate in this study from June 2016 to December 2018. The ZBI‐12 form was completed immediately preoperatively and 3 and 6 months after postoperatively. In the minor amputation group, the mean age of the 51 patients was 72.1 years. In the major amputation group, the mean age of the 88 patients was 73.7 years. Both groups of caregivers of patients with minor amputation and major amputations showed a significant improvement in ZBI‐12 score when compared preoperatively and at 3‐ and 6‐month follow‐up visits. The mean ZBI‐12 score was significantly higher in the major than in the minor amputation group in preoperative and all postoperative visits. The absence of the ankle joint in the below‐ or above‐knee amputation renders it more difficult for the amputee to quickly learn the use of prosthesis, thereby increasing the burden of the patient and caregivers. We found that lower extremity amputation for the treatment of chronic diabetic foot ulcers has significantly favourable effect on the caregiver burden, and thereby heel sparing was considerably more effective for the caregiver burden.     

Critical care nurses' knowledge,attitudes, and practices of pressure injury prevention in China: A multicentric cross-sectional survey

Pressure injury is a serious and preventable problem in intensive care units. Translating guidelines into clinical practice can reduce the incidence of pressure injury. Identifying clinical status, barriers and facilitators contribute to guideline implementation. To identify the knowledge, attitudes, and practices of pressure injury prevention in Chinese critical care nurses. Secondary data were extracted from a multicentric clinical trial. Knowledge and attitudes toward pressure injury prevention were assessed by a fourteen-item questionnaire. The observed practices were recorded using a case report form. The report complies with the STROBE statement. A total of 950 critical care nurses in 15 hospitals from six provinces of China were investigated. A total of 53.1% of nurses received a median score of 6 points or less. Knowledge regarding the repositioning procedure, risk assessment, and heel pressure injury prevention was insufficient. Over 99% of nurses strongly or somewhat agreed that pressure injury prevention was very important and that they were willing to take measures to prevent pressure injury. A total of 27 781 patient days of pressure injury prevention practice were recorded. Repositioning was the most commonly used prevention measure, followed by support surfaces and prophylactic dressings. A combination of repositioning, support surface, and prophylactic dressing was lacking. Chinese critical nurses showed a low level of knowledge and a positive attitude toward pressure injury prevention. Practices of pressure injury prevention were unsatisfactory. There is a clear gap between the guidelines and clinical practices. The barrier (low-level knowledge) and facilitator (positive attitude) were identified in this study. According to these findings, strategies need to be developed to promote guideline implementation.

Effect of diabetic foot ulcers and other risk factors on the prevalence of lower extremity amputation: A meta-analysis

A meta-analysis study was conducted to measure the consequence of diabetic foot ulcers (DFUs) and other risk factors (RFs) on the prevalence of lower extremity amputation (LEA). A comprehensive literature inspection till February 2023 was applied and 2765 interrelated studies were reviewed. Of the 32 chosen studies enclosed, 9934 subjects were in the chosen studies' starting point, and 2906 of them were with LEA. Odds ratio (OR) in addition to 95% confidence intervals (CIs) were used to compute the value of the effect of DFUs and other RFs on the prevalence of LEA by the continuous and dichotomous approaches and a fixed or random effect model. Male gender (OR, 1.30; 95% CI, 1.17–1.44, P < .001), smoking (OR, 1.24; 95% CI, 1.01–1.53, P = .04), previous foot ulcer (OR, 2.69; 95% CI, 1.93–3.74, P < .001), osteomyelitis (OR, 3.87; 95% CI, 2.28–6.57, P < .001), gangrene (OR, 14.45; 95% CI, 7.03–29.72, P < .001), hypertension (OR, 1.17; 95% CI, 1.03–1.33, P = .01), and white blood cells count (WBCC) (MD, 2.05; 95% CI, 1.37–2.74, P < .001) were significantly shown to be an RF in LEA in subjects with DFUs. Age (MD, 0.81; 95% CI, −0.75 to 2.37, P = .31), body mass index (MD, −0.55; 95% CI, −1.15 to 0.05, P = .07), diabetes mellitus type (OR, 0.99; 95% CI, 0.63–1.56, P = .96), and glycated haemoglobin (MD, 0.33; 95% CI, −0.15 to 0.81, P = .17) were not shown to be an RF in LEA in subjects with DFUs. Male gender, smoking, previous foot ulcer, osteomyelitis, gangrene, hypertension, and WBCC were significantly shown to be an RF in LEA in subjects with DFUs. However, age and diabetes mellitus type were not shown to be RF in LEA in subjects with DFUs. However, caused of the small sample sizes of several chosen studies for this meta-analysis, care must be exercised when dealing with its values.
