Plain English Summary

Background and study aims
About 7 in 10 of A&E admissions are alcohol related at peak times. Urban centres typically produce a substantial share of all alcohol-related violence, and are particularly associated with severe intoxication and violent injury. Recent studies have shown that environment-specific risk factors and recognition that premises-level (PL) programs (interventions) that address such risks can lead to a reduction in alcohol-related violence. Interventions that address these risk factors are therefore urgently required to reduce the burden of harm to health services. By reducing known risk factors within premises and their immediate environment, the aim is to directly or indirectly reduce alcohol misuse and/or injury.

Who can participate?
Premises are eligible for the trial if they are on-licence premises that are: based within the 22 local authorities (LAs) in Wales, are a public house, night club, or hotel, and have recorded one or more violent incidents (including Section 18/20, Section 47, common assault, affray, assault of a police officer) in the previous twelve months.

What does the study involve?
The study is being delivered by Environmental Health Officers (EHOs) in Wales. The intervention itself is made up of three components. First, EHOs will audit premises to identify areas where premises operation might increase the risk of violence (e.g. inappropriate alcohol promotions, which are associated with violence). Second, based on the outcome of the audit, EHOs will take one of four possible steps: 1) take no further action if there are no risks; 2) advise premises to make changes; 3) formally require premises to make changes; 4) refer premises to police and Local Authority (LA) licensing officers (who are able to place conditions on premises licenses). Finally, EHOs will conduct a second audit in premises where further action is required to assess whether the required changes have been made (they will enforce as required). Depending upon the severity of the risk identified in the initial audit, the second audit will take place either one month or three months later. The control group premises will receive the usual contact that premises receive from EHOs, which does not routinely involve interventions for violence. Following the audit, we will provide premises staff with training and instructional materials designed to engage them in harm reduction practice, and will be tailored to the areas of risk identified on a per-premises basis.

What are the possible benefits and risks of participating?
If this intervention succeeds in reducing violence then there will be substantial benefits such as reducing fear of crime and the psychological impact of victimisation. Due to the nature of the trial we don't foresee any risks over and above those usually associated with licensed premises.

Where is the study run from?
The trial is being run from Cardiff University Dental School

Study information

Scientific title

Randomised controlled trial of All-Wales Licensed Premises Intervention to reduce alcohol-related violence



Study hypothesis

Primary objective
To determine the impact of Safety Management in Licensed Premises (SMILE) on police recorded violence

Secondary objectives
1. To assess whether intervention impacts change over time
2. To identify the costs associated with SMILE and the extent to which it can be regarded as an efficient use of public funds
3. To assess whether the integrity of SMILE is maintained across LAs
4. To determine the optimal format of the risk-led PL intervention for delivery by EHOs
5. To develop a revised logic model of the intervention
6. To consider the relationship between outcomes and intervention reach, dose and receipt

Public Health Research


1. An evaluation of the Safety Management in Licensed Premises (SMILE) intervention
2. The control group premises will receive the usual contact that premises receive from EHOs, which does not routinely involve interventions for violence.

Intervention type



Not Applicable

Drug names

Primary outcome measure

Difference in police-recorded violence between intervention and control premises over a 12 month follow-up period

Secondary outcome measures

The trial will incorporate an embedded Process Evaluation (PE) to examine how the trial is implemented and to facilitate interpretation of outcome effects.

The PE will examine the following issues:
1. Trial arm implementation and context
2. Trial arm fidelity
3. Participation, reach and dose delivered
4. Reception and responsiveness

The trial will also include an embedded economic evaluation to determine the cost of delivering the intervention.
