The objective of this 20-week quality improvement study was to use the Model for Improvement and Plan-Do-Study-Act (PDSA) cycles to improve adherence in Danish nursing homes. We included two nursing homes with 109 residents at baseline. An information sheet including the rationale for the recommendation was developed for the nurses to urge residents to take the supplements and seek approval by the general practitioner afterwards (PDSA cycle 1). Moreover, it was included in admission meetings with new residents to address supplementation (PDSA cycle 2). A nurse reviewed patient records for number of residents prescribed adequate doses of vitamin D (\u226520 \u00b5g) and calcium (\u2265800 mg) before, during and after the intervention. At baseline, 32% (n = 35) of the residents had adequate doses of vitamin D and calcium. After implementation of the information sheet and adjustment to admission meetings, this increased to 65% (n = 71) at endpoint (p &lt; 0.001). In conclusion, in this quality improvement study, we improved the number of prescriptions of adequate doses of vitamin D and calcium over 20 weeks using the Model for Improvement and PDSA experiments.<\/jats:p>","DOI":"10.3390\/nu14245360","type":"journal-article","created":{"date-parts":[[2022,12,19]],"date-time":"2022-12-19T07:59:21Z","timestamp":1671436761000},"page":"5360","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Vitamin D and Calcium Supplementation in Nursing Homes\u2014A Quality Improvement Study"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4965-4331","authenticated-orcid":false,"given":"Charlotte","family":"Mortensen","sequence":"first","affiliation":[{"name":"Department of Nursing and Nutrition, Faculty of Health, University College Copenhagen, 2200 Copenhagen, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2495-2511","authenticated-orcid":false,"given":"Inge","family":"Tetens","sequence":"additional","affiliation":[{"name":"Department of Nutrition, Exercise and Sports, Faculty of Science, University of Copenhagen, 1958 Frederiksberg, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Kristensen","sequence":"additional","affiliation":[{"name":"Department of Nursing and Nutrition, Faculty of Health, University College Copenhagen, 2200 Copenhagen, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1210-0167","authenticated-orcid":false,"given":"Anne Marie","family":"Beck","sequence":"additional","affiliation":[{"name":"Dietetic and Nutritional Research Unit, Herlev Gentofte Hospital, 2730 Herlev, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Nordic Council of Ministers (2014).
