P337 Bone health status and audit of DEXA scan frequency of adults with cystic fibrosis at a UK centre

Adults with CF are at increased risk of low bone mineral density (BMD), single-centre studies reporting up to 70% may have lower than expected BMD due factors such as lung disease, cortico-steroid treatment, body mass index (BMI), nutrient malabsorption, and insufficient weight bearing exercise. guidelines recommend screening patients using dual energy x-ray absorptiometry (DEXA) specific intervals enable identification timely management BMD. This audit was conducted assess health status adults a UK centre. A retrospective in September 2022 medical records. Data collected included number & gender, date last DEXA scan, lowest Tor Z score site, latest vitamin D BMI. 86 were (41 females 45 males). 88% had on time line recommended guidance, whilst 12% overdue scan. 48% normal (a >-1), 31% between –1 –2 (11 15 males), 21% <–2) (7 12 the lumbar spine 53% cohort, 22% left hip, 25% femoral neck. 84% sufficient levels D, 13% insufficiency, 3% deficient.
