PREDICTORS FOR HIDDEN PROBLEM DRINKERS IN GENERAL PRACTICE

In The Netherlands general practice attenders are not usuallyquestioned about their drinking habits. The objective of thisstudy was to determine to what extent easily available data(e.g. age, gender) can be used to identify categories of patientswho are at risk of problem drinking as a preliminary to moreintensive screening. Sixteen practices with a total populationof 32,000 patients were involved in the study. All problem drinkersknown by their GPs and a random sample of one in ten patientsnot thought to be problem drinkers were admitted to the studyat their first surgery visit during a 1-year period. A screeningquestionnaire was used to find hidden problem drinkers amongstthe individuals thought to be non-problem drinkers. The overallresponse rate was 91% (n=1405). Problem drinking was detectedin 6% (n=82) of the group regarded by the GPs as non-problemdrinkers (n=1283). Male gender, smoking, life events and chronicsocial problems were the strongest non-alcohol-related predictorsof hidden problem drinking. We conclude that a pre-selectionof patients with a greater risk of problem drinking can be madewithout information related directly to alcohol. Case-findingin this category is much more effective and probably much moreacceptable both to the GP and the patients, than the screeningof all patients.
