Giant cell arteritis (GCA) is treated with high dose glucocorticoids and progressively reduced over months to years. We undertook an audit to evaluate self-reported adherence to the original recommended glucocorticoid course and explored reasons for any variation. We recruited patients attending a single rheumatology department over 18 months. Respondents were given two self-administered questionnaires to record information regarding their use of glucocorticoids during the last 7 days and during the last 6 months. We retrieved 132 questionnaires (of whom 6 were discarded as incomplete). All data was analysed using SPSS Statistics v22. Of the 126 patients (mean age 74.9 ± 7.7 years), 59% were female. The mean duration of disease was 22.5 ± 19.1 months in patients with GCA and 32.9 ± 29.9 months in those with GCA and polymyalgia rheumatica (PMR). The mean daily number of medications taken was 9.2 ± 5.2 (range: 1 - 30); the mean number of types of daily tablets taken was 5.0 ± 2.1 (range: 1 - 10). The mean daily number of glucocorticoid tablets taken was 3.2 ± 2.6 (range: 0 - 12), with a mean daily dose of 11.1 ± 10.3 mg (range: 0 - 60 mg). Overall, in the last 7 days, 22% and in last 6 months, 40% of patients were not following their original recommended steroid regimens (Table 1). The total mean glucocorticoid dose in the last 7 days group (n = 81) was 77.8 ± 70.1 mg/week (11.1 ± 10.1 mg/day) whilst the total mean glucocorticoid dose in the last 6 months group (n = 45) was 1782.0 ± 1543.3 mg/6 month (9.9 ± 8.6 mg/day). Most respondents stated their glucocorticoid non-adherence was due to medical advice; other reasons included forgetting, fear of side effects, or confusion about different preparations of prescribed glucocorticoids. The presence of PMR did not influence glucocorticoid adherence. There is significant variation in the use of glucocorticoids compared to the original starting regimen in patients with GCA, with or without PMR. However, the amount of the discrepancy is small. The commonest reason for non-adherence was medical advice received from either primary or secondary care. H. Ariff: None. A. Awisat: None. J. Arnold: None. H. Al ani: None. L. O' neill: None. M.
