Shaping and shifting schemas on supervised injectable opioid treatment: findings from a cross-sectional qualitative study in two German treatment facilities.

Background: Supervised injectable opioid treatment (SIOT) is a promising alternative for people living with opioid use disorder (OUD) who have not sufficiently benefitted from oral opioid substitution treatment. Yet, SIOT utilization remains limited in Germany. We propose that this is due to beliefs, or schemas, on SIOT among people living with OUD.

Exploring Patients' Perceptions on Injectable Opioid Agonist Treatment: Influences on Treatment Initiation and Implications for Practice.

Introduction: Injectable opioid agonist treatment (iOAT) with diacetylmorphine is an effective option for individuals previously considered non-responsive to opioid substitution treatment. Despite implementation in Canada and several European countries, relatively few eligible people choose to initiate iOAT. To better understand what encourages or deters prospective patients from initiating iOAT, the current study explores patients' perceptions on iOAT and how these influence therapy initiation in practice.

Supervised on-site dosing in injectable opioid agonist treatment-considering the patient perspective. Findings from a cross-sectional interview study in two German cities.

Background: Injectable opioid agonist treatment (iOAT) is an effective option to support people living with opioid use disorder (OUD) who have not sufficiently benefitted from oral OAT. However, iOAT has been criticised based on theoretical and practical grounds for its dosing policies: Current regulations demand supervised, on-site application and require patients to frequently visit their treatment facility. The current study aims to investigate how patients experience on-site application and derive strategies to enhance the acceptability and effectiveness of iOAT-delivery.
