Determinants of implementing the ID ROLL OUT study's interventions: qualitative results

ISSUE: Antimicrobial stewardship programmes (ASP) and infectious disease (ID) specialists aim to ensure the rational use of antimicrobials and to improve patient outcomes. Whilst ASPs are established to varying degrees, ID specialists are rarely available in secondary and tertiary care hospitals in Germany. DESCRIPTION OF THE PROBLEM: With the ID ROLL OUT study, we implemented and evaluated an intervention, which comprises ASP with and without ID specialists’ consultation in ten hospitals (excl. university hospitals) in south-west Germany. Little has been reported on the medical and pharmaceutical staff's perspectives on the implementations. This study describes barriers, facilitators, and suggestions for improvement to successfully establish a large-scale multicentre intervention. The participants responsible for implementing the intervention were interviewed using semi-structured, guided interviews at two time-points (t1: n = 17; t2: n = 18). The recorded interviews were analysed for content, following Kuckartz. RESULTS: A high level of acceptance and a positive attitude towards the intervention are conducive to the intervention's successful implementation. The teams find extra time for the study and a close staff collaboration at a local team level to be helpful. The main barriers identified are a high workload, lack of acceptance by colleagues in key roles, and the Covid-19 pandemic. Lack of digitalisation and entrenched internal structures were identified as major barriers. To further improve implementation, more infectious disease training should be provided, along with support from superiors and extension of the intervention phase. Moreover, government-mandated ASP guidelines and quality management by the German Medical Association are desired and expected to contribute in the future. LESSONS: The identified determinants provide much-needed key information, which is important for the efficient, targeted and successful implementation of future similar interventions. KEY MESSAGES: • Acceptance, positive attitude and staff collaboration help to implement the intervention. • Heavy workloads and lack of support from key colleagues hinder the intervention’s implementation.
