Context-sensitive antibiotic optimization: a qualitative interviews study of a remote Australian hospital setting

Area of Science:

• Medical Science
• Public Health
• Healthcare Management

Background:

• Antibiotic resistance is a global health crisis, necessitating antimicrobial stewardship (AMS) programs.
• While AMS programs are widespread, their effectiveness in diverse healthcare settings, particularly remote ones, is questionable.
• Atypical healthcare settings may require tailored approaches to antibiotic optimization.

Purpose of the Study:

• To explore the experiences and perspectives of clinical staff regarding antimicrobial use in a remote Australian healthcare setting.
• To identify challenges and facilitators for antibiotic optimization strategies in this unique environment.

Main Methods:

• Qualitative study utilizing semi-structured interviews.
• 30 healthcare professionals (doctors, nurses, pharmacists) from a remote Queensland hospital participated.
• Thematic analysis was used to identify key challenges.

Main Results:

• Key challenges included AMS being perceived as externally driven, sidelining local knowledge.
• Perceptions of high local population risks and treatment failures created pressure for antimicrobial overuse.
• Interprofessional dynamics, hierarchical structures, and a transient workforce were significant barriers.

Conclusions:

• Successful antimicrobial regulations and practice improvement strategies must acknowledge and incorporate local context, resource constraints, and population-specific needs.
• Generic AMS approaches may be ineffective or counterproductive in remote settings.
• Respecting clinical 'know-how' and local expertise is crucial for effective antibiotic optimization.
