Background: Adherence, effectiveness and safety of SRL injections are similar for self- vs healthcare setting administration but patient preferences and device satisfaction vary. Device ease of use is associated with more favourable outcomes for other injectable hormones. Aim: To define key injectable SRL device attributes associated with optimal injection experience by people living with NETs/acromegaly and HCPs, identifying differences at 95% confidence. Methods: The survey (Jun-Nov ‘22) included active current users (≥6 months) of an SRL device for NETs/acromegaly, and for HCPs currently treating patients with NETs/acromegaly. There were 263 respondents from Australia, Canada, Chile, Denmark, Ireland, Mexico, Norway, Spain, UK, and USA: 201 patients (P), 10 caregivers (C) and 52 HCPs. In the P/C group (n=211), 157 people lived with NET and 54 with acromegaly; 74% were female. The HCP group (n=52) comprised 29 physicians, 20 nurses and 3 others (research nurse, clinical manager, patient leader) treating acromegaly (n=22), NET (n=15), or both (n=15). Results: P/C treatment duration ranged from 0.5-&gt;15y (≥3y in 61%); 49% had experience with &gt;1 SRL device type. Most HCPs (62%) were prescribers, 48% administered SRL injections, 83% had experience with &gt;1 SRL device type. In the P/C group, NET patients were significantly more likely to have injections administered by an HCP in a hospital setting (54% vs 26% with acromegaly, p=0.05). Home administration was more common among acromegaly P/C (57%; 26% self-injected, 22% by caregiver, 9% by HCP) vs NET P/C (30%; 10%, 9% and 11%, respectively). Top 3 key device attributes preferred by the P/C group were: 1) confidence that the correct amount of drug is delivered (76%); 2) quick administration with minimal pain/discomfort (68%); 3) device safety (needle-safety system, low risk of contamination; 53%).The top 3 in the HCP group was: 1) quick administration with minimal pain/discomfort (69%); 2) correct use is easy to learn, confidence in handling the device (63%); 3) confidence that the correct amount of drug is delivered (62%). Ease of learning and confidence on correct use was significantly more likely to be selected as important by HCPs than P/C (63% vs 44%, p=0.05); ‘shorter/finer needles’ was significantly more likely to be selected by P/C than HCPs (48% vs 25%; p=0.05). ‘Easy to store and transport’ was significantly more likely to be selected by people living with acromegaly vs NET (59% vs 35%, p=0.05). Conclusions: Patient opinions are important to define key device attributes impacting the injection experience. Home administration is more common in acromegaly vs NET, as reflected in P/C device attribute preferences. Identified differences in key device attributes preferred by patients and HCPs inform the decision on which SRL device best fits individual patient needs.
