Investigation of hazardous drinking

Approximately 20–25% of New Zealanders consume alcohol at a harmful or hazardous level, however, these problems will remain undetected in many of these people. A simple screening question, followed by a more in-depth questionnaire if required, can be a successful approach to identifying a patient with alcohol issues, within a general practice consultation. Laboratory tests are not routinely recommended for screening for hazardous drinking in primary care. View Article

Computerised decision support tools can help to achieve improved therapeutic control. View Article
