Exploring determinants of antimicrobial prescribing behaviour using the Theoretical Domains Framework

Area of Science:

• Medical Research
• Health Services Research
• Qualitative Research

Background:

• Limited theoretically-based qualitative studies exist on antimicrobial prescribing behavior determinants in hospitals.
• Understanding these determinants is crucial for developing effective behavior change interventions (BCIs).

Purpose of the Study:

• To explore determinants of clinicians' antimicrobial prescribing behavior using the Theoretical Domains Framework (TDF).
• To identify barriers and facilitators to appropriate antimicrobial practice in hospital settings.

Main Methods:

• Semi-structured interviews were conducted with doctors and pharmacists in Qatar.
• Interviews were analyzed using the TDF to identify prescribing determinants.

Main Results:

• Eight doctors and eight pharmacists were interviewed until data saturation.
• Barriers included guideline deficiencies, knowledge gaps, role restrictions, decision-making challenges, and poor teamwork.
• Facilitators involved guideline compliance and awareness of prescribing consequences.

Conclusions:

• Antimicrobial prescribing is complex, influenced by various barriers and facilitators.
• This study provides in-depth understanding to support effective BCIs for antimicrobial stewardship.
