Project description:This study aims to evaluate the quality of clinical practice guidelines(CPGs) for patients with diabetic foot worldwide. A search of guidelines websites, databases and academic institutions websites was performed from January 1st, 2010, until June 30th, 2018. Four assessors independently rated the quality of each CPG using the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument. Twelve CPGs satisfied the inclusion criteria. The median scores for the 6 AGREE II domains (scope and purpose, stakeholder involvement, rigor of development, clarity of presentation, applicability, and editorial independence) were 92.5%, 72.5%, 71.5%, 89%, 47%, and 77%, respectively. The overall quality of the CPGs was good since the majority of the CPGs reached an overall guideline quality between 5 and 7 points. Different CPGs had widely varying scores in the same area, ranging from 25 to 94 points.

Project description:PurposeSignificant concerns exist regarding the content and reliability of oncology clinical practice guidelines (CPGs). The Institute of Medicine (IOM) report "Clinical Practice Guidelines We Can Trust" established standards for developing trustworthy CPGs. By using these standards as a benchmark, we sought to evaluate recent oncology guidelines.MethodsCPGs and consensus statements addressing the screening, evaluation, or management of the four leading causes of cancer-related mortality in the United States (lung, breast, prostate, and colorectal cancers) published between January 2005 and December 2010 were identified. A standardized scoring system based on the eight IOM standards was used to critically evaluate the methodology, content, and disclosure policies of CPGs. All CPGs were given two scores; points were awarded for eight standards and 20 subcriteria.ResultsNo CPG fully met all the IOM standards. The average overall scores were 2.75 of 8 possible standards and 8.24 of 20 possible subcriteria. Less than half the CPGs were based on a systematic review. Only half the CPG panels addressed conflicts of interest. Most did not comply with standards for inclusion of patient and public involvement in the development or review process, nor did they specify their process for updating. CPGs were most consistent with IOM standards for transparency, articulation of recommendations, and use of external review.ConclusionThe vast majority of oncology CPGs fail to meet the IOM standards for trustworthy guidelines. On the basis of these results, there is still much to be done to make guidelines as methodologically sound and evidence-based as possible.

Project description:IntroductionFoot ulcers and amputations are common conditions in people with diabetes and can considerably impact quality of life, necessitate a lengthy hospital stay and increase mortality. Preventative foot care and examination can prevent or delay ulceration, and individuals may seek information from publicly available social media resources such as YouTube. Therefore, the purpose of this study is to evaluate the educational quality and reliability of publicly available YouTube videos on diabetes foot examinations.MethodA YouTube search for "diabetic foot examination" was conducted, and the first 100 relevant English videos focused on examining the diabetic foot were included for evaluation. The Journal of the American Medical Association (JAMA) standards were used to measure video reliability. The Global Quality Score (GQS) and the Diabetes UK Annual Foot Check (DUK-C) checklist were used to assess video educational quality. Differences in JAMA, GQS, and DUK-C ratings were analysed after videos were sorted by topic and source.ResultsThe mean number of views per video was 101,311.9 ± 348,383.6, and the mean video power index was 41.6 ± 170.0. The most common upload source was from physicians (28%) and, the most popular material category was diabetes foot examination (58 videos). In terms of video reliability, 36% of videos scored 0. According to the GQS standards, only 5% of the videos are of excellent quality, while 34% are of poor quality, with 24 videos scoring between 0 and 1 on the DUK-C scale.ConclusionWhile foot care examination videos have a substantial audience, the majority are considered low in quality and reliability. Videos on comprehensive diabetic foot examination should be accessed on reputable sources that guarantee standardisations of video quality and take into account the simplification of information transmission in order to reach lay audiences.

Project description:AimsTo utilise the 2019 International Working Group on the Diabetic Foot (IWGDF) - diabetic foot infection (DFI) guidelines as an audit tool for clinical practice in patients with diabetes attending a High-Risk Foot Service.MethodsData from 93 consecutive patients were collected over a 19-month period in patients attending a High-Risk Foot Service. The diagnosis and management of each patient in the sample were compared against the 2019 IWGDF DFI guidelines, grouped into four categories: Diagnosis, Microbiology, Treatment of soft tissue infection, and Surgical treatment and osteomyelitis. Deficits in performance were recorded using the recommendations as a benchmark standard.ResultsThere were 109 DFI events. Nineteen (63%) of the recommendations were met, 7 (24%) were partially met, and four (13%) recommendations were not met. Fourteen of the sample had no documented requests for full blood counts. Tissue was obtained for culture in 32 (29%) of the sample. No percutaneous bone biopsies were performed. Only 13 (28%) patients had intraoperative bone specimens sent for culture and sensitivities, with no bone specimens sent for histopathology. Modification of antibiotic therapy following available culture results was low, occurring in 12 out of 63 possible occasions (19%). The duration of antibiotic regimens in PEDIS 2 infections and osteomyelitis was greater than that recommended.ConclusionsUtilising the IWGDF DFI guidelines to benchmark clinical practice is a useful tool to identify gaps in clinical performance or service delivery and may help to improve patient care.

Project description:In the field of photocatalysis, the fabrication of black titania is a booming topic, as it offers a system with improved solar light harvesting properties and increased overall efficiency. The darkening of white TiO2 powders can be ascribed to surface hydroxylation, oxygen vacancies, Ti3+ centres, or a combination thereof. A handful of studies suggests these defects can be conveniently introduced by acoustic cavitation, generated during sonochemical treatment of pristine TiO2 powders. In reproducing these studies, P25 TiO2 samples were ultrasonicated for various hours with a power density of 8000 W/L, resulting in powders that indeed became gradually darker with increasing sonication time. However, HAADF-STEM revealed that extensive erosion of the sonotrode tip took place and contaminated the samples, which appeared to be the primary reason for the observed colour change. This was confirmed by UV-Vis DRS and DRIFTS, that showed no significant alteration of the catalyst surface after sonication. EPR measurements showed that only an insignificant fraction of Ti3+ centres were produced, far less than in a TiO2 sample that was chemically reduced with NaBH4. No evidence of the presence oxygen vacancies could be found. The enhanced photocatalytic activities of ultrasonicated materials reported in literature can therefore not be ascribed to the synthesis of actual black (defected) TiO2, but rather to specific changes in morphology as a result of acoustic cavitation. Also, this study underlines the importance of considering probe erosion in sonochemical catalyst synthesis, which is an unavoidable side effect that can have an important impact on the catalyst appearance, properties and performance.

Project description:AimsDiabetes-related amputations are typically preceded by a diabetic foot ulcer (DFU) but models to assess the quality of care are lacking. We investigated a model to measure inpatient and outpatient quality.MethodsCohort study among adults hospitalized with a DFU to a safety-net hospital during 2016. We measured adherence to DFU-related quality metrics based on guidelines during and 12 months following hospitalization. Inpatient metrics included ankle-brachial index measurement during or 6 months prior to hospitalization, receiving diabetes education and a wound offloading device prior to discharge. Outpatient metrics included wound care ≤30 days of discharge, in addition to hemoglobin A1c (HbA1c) ≤8%, tobacco cessation, and retention in care (≥2 clinic visits ≥90 days apart) 12 months following discharge.Results323 patients were included. Regarding inpatient metrics, 8% had an ankle brachial index measurement, 37% received diabetes education, and 20% received offloading prior to discharge. Regarding outpatient metrics, 33% received wound care ≤30 days of discharge. Twelve months following discharge, 34% achieved a HbA1c ≤8%, 13% quit tobacco, and 52% were retained in care. Twelve-month amputation-free survival was 71%.ConclusionsOur model demonstrated large gaps in DFU guideline-adherent care. Implementing measures to close these gaps could prevent amputations.

Project description:BackgroundMost diabetic foot amputations are caused by ulcers on the skin of the foot i.e. diabetic foot ulcers. Early identification of patients at high risk for diabetic foot ulcers is crucial. The 'Simplified 60-Second Diabetic Foot Screening Tool' has been designed to rapidly detect high risk diabetic feet, allowing for timely identification and referral of patients needing treatment. This study aimed to determine the clinical performance and inter-rater reliability of 'Simplified 60 Second Diabetic Foot Screening Tool' in order to evaluate its applicability for routine screening.Methods and findingsThe tool was independently tested by n=12 assessors with n=18 Guyanese patients with diabetes. Inter-rater reliability was assessed by calculating Cronbach's alpha for each of the assessment items. A minimum value of 0.60 was considered acceptable. Reliability scores of the screening tool assessment items were: 'monofilament test' 0.98; 'active ulcer' 0.97; 'previous amputation' 0.97; 'previous ulcer' 0.97; 'fixed ankle' 0.91; 'deformity' 0.87; 'callus' 0.87; 'absent pulses' 0.87; 'fixed toe' 0.80; 'blisters' 0.77; 'ingrown nail' 0.72; and 'fissures' 0.55. The item 'stiffness in the toe or ankle' was removed as it was observed in only 1.3% of patients. The item 'fissures' was also removed due to low inter-rater reliability. Clinical performance was assessed via a pilot study utilizing the screening tool on n=1,266 patients in an acute care setting in Georgetown, Guyana. In total, 48% of patients either had existing diabetic foot ulcers or were found to be at high risk for developing ulcers.ConclusionsClinicians in low and middle income countries such as Guyana can use the Simplified 60-Second Diabetic Screening Tool to facilitate early detection and appropriate treatment of diabetic foot ulcers. Implementation of this screening tool has the potential to decrease diabetes related disability and mortality.

Project description: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.

Project description:BackgroundOne of the most common (and costly) complications of diabetes are diabetic foot ulcers, which often result in lower-extremity amputation. Regular foot care can reduce complications; however, roughly half of Canadians with diabetes do not participate in screening. We sought to evaluate the economic effects of using telemonitoring for diabetic foot ulcer prevention using mathematical modelling.MethodsWe used Markov modelling to compare current screening standards (standard care) to population-wide and targeted (high-risk) telemonitoring programs in a hypothetical cohort of Canadian patients aged 60 years. We varied the effectiveness (or outcome), defined as the proportion of diabetic foot ulcers prevented, to explore cost-effectiveness using model parameters from published literature and clinical experts.ResultsAt 20%-40% effectiveness, population-based prevention resulted in 0.00399-0.00790 quality-adjusted life years (QALYs) gained per person over 5 years and an incremental cost of $479-$402 compared to standard care. At 15%-40% effectiveness, high-risk prevention resulted in a cost decrease per person over 5 years ($1.26-$25.55), with health benefits of 0.000207-0.00058 QALYs gained.InterpretationThe use of telemonitoring in the diabetic lower extremity can offer patients better quality of life and can be cost-effective compared to current Canadian screening practices. Future work should focus on developing and validating technologies based on objective outcome measures for remote monitoring of the diabetic foot.

Project description:ObjectivesThe purposes of this study are to perform a large-scale evaluation of the standardized dosage adjustment nomogram recommended by the American College of Chest Physicians (CHEST) for the management of enoxaparin in hospitalized pediatric patients and to determine the necessity of routine and repeated anti-factor Xa (anti-Xa) levels.MethodsA retrospective cohort study was designed, and charts were reviewed in a single tertiary care institution for all patients who received enoxaparin between October 1, 2010, through September 30, 2016. Patients were included if they were receiving treatment doses of enoxaparin according to the pediatric CHEST guidelines, had a subtherapeutic or supratherapeutic anti-Xa level drawn at 3.5 to 6 hours after a dose, had a dose changed in an attempt to attain a therapeutic anti-Xa level, and had a second anti-Xa level drawn 3.5 to 6 hours after the dose change. Descriptive statistical methods were used to characterize the ability of dose adjustment via a nomogram to attain an anti-Xa of 0.5 to 1 unit/mL.ResultsA total of 467 patients were identified who received the appropriate initial dose and dosage adjustment and whose levels were drawn according to the CHEST guidelines. In patients who had an initial anti-Xa level of <0.35 units/mL and received the nomogram recommended dose increase of 25% ± 5%, 28 out of 96 patients (29.2%) reached therapeutic levels. Of 197 patients who had an initial anti-Xa level between 0.35 and 0.49 units/mL and who received the nomogram recommended dose increase of 10% ± 5%, 116 (58.9%) reached therapeutic levels. Of 50 patients with an initial anti-Xa level between 1.1 and 1.5 units/mL and who received the nomogram dose decrease of 20% ± 5%, 31 (62%) reached therapeutic levels.ConclusionsThe current dosage adjustment nomogram recommended by the CHEST guidelines does not reliably lead to therapeutic anti-Xa levels when used to adjust enoxaparin doses in pediatric patients.
