Organizational changes in diabetic foot care practices for patients at low and moderate risk after implementing a comprehensive foot care program in Alberta, Canada

What are the current diabetic foot assessment methods in private podiatry practices in Flanders, Belgium: an exploratory mixed method study

BACKGROUND

Diabetic foot assessments detect patients at risk for developing a diabetes-related foot ulceration and can significantly reduce the risk of amputation. In order to organize this assessment effectively, diabetic foot assessment guidelines are required according to the International Working Group of the Diabetic Foot. However, these international guidelines have not been adapted into a national guideline for podiatrists in Flanders, Belgium. This study aims to identify the methods and guidelines currently used to assess the diabetic foot in private podiatry practices in Flanders, Belgium and to explore the podiatrists' opinions on developing a national diabetic foot assessment guideline.

METHODS

This exploratory mixed method study was composed of an anonymous online survey comprising of open- and closed-ended questions followed by 1:1 online semi-structured interviews. Participants were recruited via e-mail and a closed private Facebook group of podiatry alumni. Data was analyzed using SPSS statistics and thematic analysis described by Braun and Clarke.

RESULTS

This study showed that the vascular assessment of the diabetic foot exists solely of a medical history and palpation of the pedal pulses. Non-invasive tests such as doppler, toe brachial pressure index or ankle brachial pressure index are seldom used. Only 66% reported to use a guideline for the diabetic foot assessment. There was a variety of reported guidelines and risk stratification systems in use in private podiatry practices in Flanders, Belgium.

CONCLUSION

Non-invasive tests such as the doppler, ankle brachial pressure index or toe brachial pressure index are rarely used for the vascular assessment of the diabetic foot. Diabetic foot assessment guidelines and risk stratification systems to identify patients at risk for developing a diabetic foot ulcer were not frequently used. International guidelines of the International Working Group of the Diabetic Foot have not yet been implemented in private podiatry practices in Flanders, Belgium. This exploratory research has provided useful information for future research studies.

Screening behaviors for diabetic foot risk and their influencing factors among general practitioners: a cross-sectional study in Changsha, China

BACKGROUND

Diabetic foot is a serious complication of diabetes with a high disability and mortality rate, which can be prevented by early screening. General practitioners play an essential role in diabetic foot risk screening, yet the screening behaviors of general practitioners have rarely been studied in primary care settings. This study aimed to investigate foot risk screening behaviors and analyze their influencing factors among general practitioners.

METHODS

A cross-sectional study was conducted among 844 general practitioners from 78 community health centers in Changsha, China. A self-designed and validated questionnaire was used to assess the general practitioner's cognition, attitude, and behaviors on performing diabetic foot risk screening. Multivariate linear regression was conducted to investigate the influencing factors of risk screening behaviors.

RESULTS

The average score of diabetic foot risk screening behaviors among the general practitioners was 61.53 ± 14.69, and 271 (32.1%) always or frequently performed foot risk screening for diabetic patients. Higher training frequency (β = 3.197, p < 0.001), higher screening cognition (β = 2.947, p < 0.001), and more positive screening attitude (β = 4.564, p < 0.001) were associated with more diabetic foot risk screening behaviors, while limited time and energy (β=-5.184, p < 0.001) and lack of screening tools (β=-6.226, p < 0.001) were associated with fewer diabetic foot screening behaviors.

CONCLUSION

The score of risk screening behaviors for the diabetic foot of general practitioners in Changsha was at a medium level. General practitioners' diabetic foot risk screening behaviors may be improved through strengthening training on relevant guidelines and evidence-based screening techniques, improving cognition and attitude towards foot risk screening among general practitioners, provision of more general practitioners or nurse practitioners, and user-friendly screening tools.

Variation in treatment and outcomes for patients with chronic limb-threatening ischaemia in New South Wales, Australia

BACKGROUND

Chronic limb-threatening ischaemia (CLTI) carries significant amputation and mortality risks. Australian population-based outcomes for CLTI are inadequately known. This study aimed to distinguish factors associated with outcomes in the first 2 years after CLTI surgery.

METHODS

By linking routinely collected health administrative and mortality data from New South Wales, this population-based cohort study identified patients with ischaemic rest pain, gangrene or ulceration undergoing vascular surgery in public hospitals between 2010 and 2012. The primary outcome was 2-year amputation-free survival (AFS), and secondary outcomes included readmission and reoperation rates. Multivariable regression analysis identified prognostic factors adjusted for patient, hospital and geographic factors.

RESULTS

Primary CLTI surgery was performed on 4898 patients. Almost half the cohort had minor amputations without concurrent revascularization (2398, 49%), and the remaining patients had open (652, 13%) or endovascular (1848, 38%) surgery. At 2-years, the AFS rate was 72%. Significant disparity was seen between age groups, with the 2-year AFS 71% in patients aged 75 years or older, compared to 95% in patients aged less than 75 years (P < 0.001). Place of residence or hospital training status did not significantly influence AFS or readmission, but non-training hospitals had higher rates of reoperation.

CONCLUSION

This population-based cohort study demonstrated variable outcomes for patients with CLTI, particularly with respect to older age, admission acuity and comorbidity. Results may guide service improvements however further research is needed into how population-wide health initiatives can address age-related disparities in CLTI.
