We previously showed that an evidence-based SLE patient decision aid was more effective than the SLE information pamphlet provided by the American College of Rheumatology in reducing decisional conflict for the choice of immunosuppressive medications in women with lupus nephritis, with higher acceptability and feasibility. The aim of this study was to assess patient outcomes from the implementation of this SLE patient decision aid on disease management in people with SLE.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;This prospective implementation study was done in 15 geographically diverse rheumatology clinics across the USA. Adults aged 18 years or older with a diagnosis of SLE identified based on a medical record review were included. There were no exclusion criteria. Participants were invited to view the computerised SLE patient decision aid, provided through a touchscreen tablet, a website, or a smartphone app during a regular clinic visit with their rheumatologist at baseline (viewing at follow-up visits was optional). Participants viewed either the full or abbreviated (lite) version, based on SLE disease activity and treatment, as recommended by their rheumatologist. Participants completed validated computerised surveys at each of the baseline, 3-month, and 6-month clinic visits on touchpad computers or their mobile phone (depending on patient preference). These surveys included questions related to patient decisional conflict, shared decision making, patient-physician communication, and perceived acceptability and feasibility of the decision aid. The main outcome of this study was to assess the impact of the SLE patient decision aid (both full and lite versions) on patient decisional conflict, shared decision making, patient-provider communication, and perceived acceptability and feasibility. The study had a multistakeholder committee that included people with lived experience of SLE. This study was registered at ClinicalTrials.gov, NCT03735238.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Findings: &lt;/strong&gt;Between May 23, 2019, and Dec 12, 2023, 2005 patients with SLE were assessed for eligibility and 1895 were included in the study. Study participants had a mean age of 44·7 years (SD 14·4); of the 1855 respondents with data on sex, 1731 (93·3%) were female and 124 (6·7%) were male; of the 1832 respondents with data on race, 827 (45·1%) were African American.

Here we present the most up-to-date global, regional, and national estimates of the contribution of low bone mineral density to the burden of fractures from falls and additional categories of injuries from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;The burden of low bone mineral density was estimated from 1990 to 2020 in terms of years lived with disability (YLDs), disability-adjusted life years (DALYs), and deaths, for individuals aged 40 years and older, using data from population-based studies from 48 countries or territories (169 unique sources). Mean standardised femoral neck bone mineral density values were estimated by GBD location, age, and sex by meta-regression. Based on a separate meta-analysis of population-based studies from nine countries (12 unique sources), we also estimated the pooled relative risk of fractures per unit decrease in bone mineral density (g/cm&lt;sup&gt;2&lt;/sup&gt;). The population-attributable fraction for low bone mineral density was calculated by comparing the observed distributions of standardised femoral neck bone mineral density to an age-specific and sex-specific counterfactual distribution, defined as the 99th percentile of five rounds of the National Health and Nutrition Examination Survey in the USA, by 5-year age group and sex. Hospital and emergency department data were used to derive the incidence of fractures for six categories of injury (road injuries, other transport injuries, falls, non-venomous animal contact, exposure to mechanical forces, and physical interpersonal violence) using ICD codes. Deaths due to fractures were estimated as the proportion of in-hospital deaths due to the specified injury causes for which a fracture (nature of injury code) was more severe than the cause of injury code. YLDs and DALYs attributable to low bone mineral density by cause of injury were also determined according to previous GBD methods.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Findings: &lt;/strong&gt;In 2020, 8·32 million (95% UI 5·58-10·84) YLDs, 17·2 million (14·1-20·2) DALYs, and 477 000 (411 000-536 000) deaths were attributable to low bone mineral density globally in individuals aged 40 years and older. Between 1990 and 2020, global YLDs, DALYs, and deaths attributable to low bone mineral density increased by 91·8% (88·5-95·1), 89·8% (81·5-99·0), and 127·1% (108·5-144·5), respectively. Over this period, the age-standardised global rates of YLDs, DALYs, and deaths attributable to low bone mineral density showed modest decreases. In 2020, falls accounted for 76·2% (95% UI 74·2-78·3) of YLDs, 65·2% (62·9-67·6) of DALYs, and 71·0% (67·4-72·8) of deaths attributable to low bone mineral density, and road injuries largely accounted for the remaining amount: 12·4% (11·1-13·6) of YLDs, 24·6% (22·5-27·1) of DALYs, ","PeriodicalId":48540,"journal":{"name":"Lancet Rheumatology","volume":" ","pages":""},"PeriodicalIF":16.4,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145092803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
