This retrospective national cohort study analyses the epidemiological status of DFU patients in relation to urgent and elective hospitalizations, amputation rates, and deaths in Poland from 2017 to 2019, and during 2020 when the COVID-19 pandemic began. The data were obtained from national medical records gathered by the National Health Fund (NHF). Discharge diagnoses were categorized according to ICD-10 and ICD-9 codes. Analysis of the data showed a statistically significant decrease in elective hospital admissions (from 29.6% to 26.3%, p = 0.001). There was a decrease in the percentage of hospitalizations related to limb-salvage procedures (from 79.4% to 71.3%, p = 0.001). The opposite tendency was observed among urgent hospital admissions (from 67.0% to 73.2%, p = 0.01), which was related to a significant increase in the number of minor amputations (from 3146 to 4269, p = 0.017). This rise was in parallel with the increase in the percentage of patients who died during hospitalization due to DFU (from 3.9% to 4.8%, p = 0.03). The number of deaths has not changed significantly (from 590.7 to 668.0, p = 0.26). The results of the conducted analyses confirm the negative tendencies in the medical care of patients with DFU during the first year of the pandemic in Poland. Changes in therapy schemes and stronger patient support following this period are necessary to avoid further complications in patients with DFU.<\/jats:p>","DOI":"10.3390\/ijerph19073827","type":"journal-article","created":{"date-parts":[[2022,3,23]],"date-time":"2022-03-23T12:20:25Z","timestamp":1648038025000},"page":"3827","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Breakdown of Diabetic Foot Ulcer Care during the First Year of the Pandemic in Poland: A Retrospective National Cohort Study"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1562-8450","authenticated-orcid":false,"given":"Marcin","family":"Kleibert","sequence":"first","affiliation":[{"name":"Department of Diabetology and Internal Diseases, Medical University of Warsaw, 02-097 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1160-9204","authenticated-orcid":false,"given":"Beata","family":"Mrozikiewicz-Rakowska","sequence":"additional","affiliation":[{"name":"Department of Diabetology and Internal Diseases, Medical University of Warsaw, 02-097 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8259-0718","authenticated-orcid":false,"given":"Patrycja Ma\u0142gorzata","family":"B\u0105k","sequence":"additional","affiliation":[{"name":"Department of Diabetology and Internal Diseases, Medical University of Warsaw, 02-097 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel","family":"Ba\u0142ut","sequence":"additional","affiliation":[{"name":"Department of Diabetology and Internal Diseases, Medical University of Warsaw, 02-097 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jakub","family":"Zieli\u0144ski","sequence":"additional","affiliation":[{"name":"Interdisciplinary Centre for Mathematical and Computational Modeling, University of Warsaw, 02-106 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Leszek","family":"Czupryniak","sequence":"additional","affiliation":[{"name":"Department of Diabetology and Internal Diseases, Medical University of Warsaw, 02-097 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"943","DOI":"10.1111\/jch.13912","article-title":"COVID-19 and diabetes: Is there enough evidence?","volume":"22","author":"Tadic","year":"2020","journal-title":"J.
