Introduction: This global survey evaluated the practices and adherence to international Clinical Practice Consensus Guidelines (CPCG) of physicians involved in pediatric diabetes care regarding screening, prevention and treatment of vascular complications of type 1 diabetes (T1D). Method: A web-based survey gathering data about respondents’ background, practices related to screening, prevention, and treatment of diabetic nephropathy, retinopathy, neuropathy and macrovascular diseases and a self-assessment of physicians’ knowledge based on the ISPAD CPCG 2018 was shared by ISPAD. Results: We received 175 responses from 62 countries (60% female, median age 42.3 years, 72.0% ISPAD members). Two-thirds of respondents initiated nephropathy and retinopathy screening per CPCG recommendations. Only half of them adhered to recommendations for neuropathy and macrovascular disease risk factors (RFs). Over 85% of respondents used the recommended screening method for nephropathy, retinopathy and macrovascular disease RFs, and only 59% for neuropathy. Lack of access to neuropathy and macrovascular diseases RF screening methods was reported by 22.2% and 11.8% of respondents, respectively. Adherence to recommended screening frequency varied: 92% for nephropathy, around two-thirds for neuropathy and macrovascular disease RFs, and only 17.7% for retinopathy. Most participants aligned their practices for treating T1D complications with CPCG recommendations, except for nephropathy. Significant differences in adherence to CPCG and individuals’ financial contributions reflected countries' income levels. Around 50% of the respondents were very familiar with the ISPAD CPCG content. Conclusion: Our study highlights global variation in adherence to CPCG for T1D vascular complications, which is influenced by country income and healthcare disparities. It also revealed knowledge gaps among physicians on this critical topic.
