Background:
     
     This collaborative study by The Australasian College of Paramedicine's Clinical Practice Guidelines (CPG) Working Group aimed to examine CPG development practices in Australian and New Zealand ambulance services.
   

Methods:
     
     Employing a qualitative descriptive design, the research utilised thematic analysis to extract insights from interviews with eleven experts actively involved in CPG development. The study embraced a nominalist and constructivist approach, recognising the intricate connection between individual experiences and the realities of CPG development in the paramedic field.
   

Results:
     
     Key findings revealed significant heterogeneity in CPG development practices, emphasising a lack of formal training and a substantial reliance on existing guidelines. The study highlighted challenges in project management flexibility, limited research capacity, and inconsistencies in external consultations and resource utilisation.
   

Conclusion:
     
     The study recommends adopting project management frameworks, investing in training, and utilising evidence evaluation methodologies like GRADE. It emphasises the need for multidisciplinary teams and formal expertise in evidence synthesis, advocating for targeted training programs. Funding challenges highlight the importance of dedicated budgets and collaborative efforts for resource allocation. Knowledge translation and implementation issues underscore the significance of training programs for evidence evaluation and knowledge translation in overcoming these challenges.
