Summary

• Control group, no training
• Deteriorated according to DSI
• Improvement on VSP and VHI
• Lack of knowledge and awareness
• Indirect group
• Improvement on DSI
• Self rated deterioration on VSP
• Direct group
• Improvement on DSI and VSP
• Training provided both cognitive and behavioural
  skills

Conclusions

• Direct training the best form of prevention
• Awareness and behavioural skills
• Training is required to ensure good practice
• Further large scale study and follow up
