title: [Discriminative capacity of a simple question as a screening for hazardous and harmful alcohol consumption in a university medical service].
abstract: BACKGROUND
  Alcohol misuse has been recognized as a public health problem in universities. It is possible to achieve a preventive approach if early identification of people with risky and harmful drinking patterns is achieved. There are multiple screening instruments with acceptable sensitivity. The National Institute on Alcohol Abuse and Alcoholism (NIAAA) has recommended the use of a simple question to screen hazardous and harmful alcohol consumption in primary care and their incorporation into routine clinical practice.
  
  
  OBJECTIVE
  To determine the discriminative ability of a simple question as a screening in a student health service.
  
  
  METHODS
  We applied this question to 303 patients treated at a university medical service, followed by the AUDIT.
  
  
  RESULTS
  Using AUDIT as a reference, the sensitivity and specificity of the simple question to detect hazardous and harmful alcohol consumption was 0.90 (95% CI: 0.68-0.98) and 0.76 (95% CI: 0.70-0.80), respectively, with a negative predictive value of 99.1%.
  
  
  CONCLUSIONS
  The simple question can timely detect people with risky and harmful alcohol consumption in a university medical service. This requires implementing a systematic approach to timely identify and intervene in this problem.
