Abstract Objectives Telephone advice lines are a key component of rheumatology services. A national survey of telephone advice line providers was undertaken to explore how this service is currently delivered and the impact on those delivering it, to inform providers, policy makers and patients. Methods Online survey conducted between March and September 2023. This collected data on demographics, how advice lines function, governance and the impact on nurses’ wellbeing. Data were analysed using descriptive statistics. Results 123 health professionals completed the survey. The majority were rheumatology nurses (n = 118, 96%), over 45yrs (n = 112, 91%), band 7 or above (n = 92, 76%), with 77 (65%) reporting over 10 years’ experience within rheumatology. Most advice lines operated weekdays only (n = 93, 79%) with most calls returned within 2 days (n = 81, 66%) although some callers waited over 7 days (n = 19, 15%). The number of calls received monthly ranged from 100 to over 800 with 46 (37%) responders reporting over 500 calls/month. The commonest reasons for contacting advice lines were disease activity, pain and medication concerns. For most responders governance arrangements were not clear (N = 72, 61%). Providing advice lines impacted on the wellbeing of nurses providing the service. 89 (72%) felt anxious ‘sometimes to mostly’ and 79 (64%) found it ‘mostly-always’ stressful. 85 (69%) nurses had not received any training to manage advice lines. Conclusion Although telephone advice lines are provided by experienced rheumatology nurses, high demand is impacting on wellbeing. Having designated training could equip nurses with additional skills to manage increased capacity and monitor their own wellbeing.
