Evaluating home injection compared with healthcare-setting injection of somatostatin analogs: a systematic literature review.

Purpose: A systematic literature review was conducted to assess the use of home injections (self/partner/healthcare provider [HCP]-administered) of somatostatin analogs (SSAs) as an alternative to healthcare-setting injections in patients with acromegaly and neuroendocrine tumors (NETs).
Methods: MEDLINE/Embase/the Cochrane Library (2001-September 2021), key congresses (2019-2021), and bibliographies of relevant systematic reviews were searched. Eligible studies reported on efficacy/effectiveness, safety, adherence, patient-reported outcomes (PROs), and economic outcomes in populations receiving home injections of SSAs.
Results: Overall, 12 studies were included, all reporting on SSAs (lanreotide Autogel/Depot or octreotide long-acting release) in acromegaly or NETs. Across four studies, home injection was associated with similar disease control in patients with acromegaly/NETs compared with healthcare-setting administration. High rates of treatment adherence were shown in two studies of patients with acromegaly receiving lanreotide injections at home. Two studies reported non-serious adverse events; incidence of adverse reactions was similar in both the home and healthcare administration settings. Preference for injection setting varied between studies and indications; nonetheless, higher satisfaction/convenience (>75% patients) was reported for home injections. Self- or partner-injection was associated with economic savings compared with administration in the healthcare setting across five studies.
Conclusion: Efficacy/effectiveness, adherence, and safety outcomes of SSAs in the home injection setting were similar to those in the healthcare setting, with high reported satisfaction and convenience. Self/partner injection also resulted in cost savings. These findings provide a basis to understand outcomes related to home injection and encourage healthcare providers to discuss optimal treatment choices with their patients.
