The use of economic evidence to prioritise vaccines and delivery strategies to optimally use in immunisation systems is becoming a global priority, especially in low- and middle-income countries (LMICs), in view of challenges in funding and the need to make more efficient use of available resources. We undertook a scoping review to identify and synthesise available evidence on strategies that have been used to enhance the use of economic evidence in policy and decision-making in the immunisation ecosystem in LMICs. The review was also used to identify the facilitators and constraints to the use of economic evidence for vaccination policy and decision making in LMICs and the sustainability of the identified strategies.

A scoping literature review was undertaken to generate the evidence. The review adhered to the first five steps of Arksey and O’Malley’s methodological framework (identifying and refining the research questions, identifying relevant articles, selection of studies, data extraction and charting and data synthesis) and Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews.

Full-text articles were searched on PUBMED, HINARI and DOAJ using different combinations of search words as of 16 December 2024

We included articles from LMICs, including Africa, and global experiences, including those from LMICs. Papers must be written in English or have an English language translation available and published between 1 January 2004 and 16 December 2024.

Two independent reviewers used standardised methods to search, extract, and screen included studies. The findings from the review were summarized in themes that were synthesized qualitatively.

18 eligible articles met the inclusion criteria and were included in the synthesis. It was found that economic evidence was systematically requested and demonstrably influencing vaccine introduction or prioritisation decisions in only eight out of 32 LMIC settings with functional National Immunization Technical Advisory Groups (NITAGs) and in fewer than 20% of documented new vaccine introduction processes since 2015. In the majority of cases, decisions were reported as being driven primarily by disease burden, political priority, donor recommendations or historical precedent, with economic analyses either absent, produced post hoc or acknowledged but not used as a decisive factor.

There is minimal use of evidence from economics in decision-making within the immunisation ecosystem. Expert advisory committees in LMICS can, however, enhance the use of economic evidence in vaccination policy and decision-making. Hence, in order to use economic evidence for decision making, national advisory committees such as NITAGs need enhanced capacity, independence and close collaboration with researchers. LMIC NITAGs could also benefit from tailored adaptations, such as simplified cost-effectiveness tools and regional economic data hubs, to bridge this gap in decision-making and bring economic evidence to the fore of their decisions.

Prehospital notification by emergency medical services (EMS) can activate hospital resources before the patient arrives, which has been shown to improve in-hospital care for stroke patients. Optimising prehospital and handover processes in stroke care requires considering end-user perspectives to enhance acceptance and effectiveness of the developed solutions. The aim of this study was to identify current barriers in the preclinical-clinical phase of stroke care.

Within the investigator-initiated CAEHR project (CArdiovascular diseases—Enhancing Healthcare through cross-sectoral Routine data integration), an interface for transferring data from the electronic prenotification system to the hospital information system is implemented. A mixed-methods approach with semi-structured interviews as well as a cross-sectional online survey was used to gather feedback from healthcare professionals at a single stroke centre in Germany as well as from the participating EMS personnel. Data collection for the interviews was conducted between January and August 2023 and for the online survey between May and September 2023.

Interviews were conducted with 10 healthcare professionals, including seven from the neurological clinic and three from EMS. Additionally, 39 EMS employees took part in a cross-sectional online survey.

Challenges identified were educational and training aspects affecting preclinical processes and patient handover procedures, along with the opportunity for establishing more uniform protocols. Participants emphasised the importance of detailed patient information. Electronic prenotification was seen as an important step regarding structured information transmission, reducing the risk of information loss in stroke care.

The study highlights the importance of addressing organisational processes in addition to technical interfaces for implementing effective stroke care processes.
