Background. There is considerable variation within and between countries in general medical practitioners’ (GPs’) prescribing of broad-spectrum antibiotics such as fluroquinolones, and resistance to these agents is increasing worldwide. Urgently promoting cautious fluroquinolone prescribing in primary care may limit increase in resistance.

Objective. We therefore interviewed 40 GPs in order to explore the reasons for their choice of prescribed antibiotic, in particular their decision to prescribe fluroquinolones.

Methods. We used a grounded theory approach to data collection and analysis, incorporating purposive and theoretical sampling, based on high and average fluroquinolone prescribing. Interviews were conducted with 26 GPs from practices known to be high prescribers of fluroquinolone antibiotics and 14 from average fluroquinolone prescribing practices.
