BENZODIAZEPINES IN PRIMARY HEALTH-CARE - A SURVEY OF GENERAL-PRACTITIONERS PRESCRIBING PATTERNS

This paper presents the results of a survey carried out to investigate the benzodiazepine (BZD) prescribing patterns of the general practiti oners (GP) in the catchment area of a Drug Dependence Unit located in a general hospital in Mataro (Barcelona, Spain). The aims of the surve y ware: (i) to obtain descriptive information on the knowledge of the GPs about BZD and its potential for dependence; (ii) to study the freq uency of their prescribing; and (iii) to examine different factors lin ked to their prescribing. The study was carried out using a combinatio n of a personal interview and a self-administered questionnaire. A tot al of 68 doctors (88.3%) completed the questionnaire. The results show that the GPs have, in general, correct knowledge about the therapeuti c indications for BZD prescribing, but are far less aware of their pot ential to induce dependence and how to manage withdrawal. The rate of prescribing seems to be high. Furthermore, the results of the external check of validity point out that doctors tend to underestimate the nu mber of prescriptions. The majority of GPs express the need for altern ative resources to BZD prescribing. No significant associations have b een found between doctor's characteristics, such as postgraduate train ing and type of practice, and their knowledge about BZD and frequency of their prescribing. In our view, a more accurate knowledge about BZD and alternatives to its use, both factors closely linked to training, together with the availability of non-pharmacological resources, are likely to improve the quality of doctors prescribing habits, thus prev enting risks such as dependence of BZD.
