NCBI ROFL: 'Hotspots' for aggression in licensed drinking venues.

"INTRODUCTION AND AIMS: In order to better understand the social context of barroom aggression, the aim was to identify common locations ('hotspots') for aggression in bars and examine the association of hotspots with aggression severity and environmental characteristics. DESIGN AND METHODS: Aggression hotspots were identified using narrative descriptions and data recorded on premises' floor plans for 1057 incidents of aggression collected in the Safer Bars evaluation. Hierarchical Linear Modelling was used to identify bar-level and night-level characteristics associated with each hotspot. RESULTS: The most common location for aggression was the dance floor (20.0% of incidents) or near the dance floor (11.5%), followed by near the serving bar (15.7%), at tables (13.1%), aisles, hallways and other areas of movement (6.2%), entrance (4.5%) and the pool playing area (4.1%).
