Alcohol consumption in Spanish primary health care providers: a national, cross-sectional study

Abstract

Aim: To estimate the prevalence of alcohol consumption and analyse the drinking patterns among primary healthcare (PHC) providers.

Design: Observational, cross-sectional, descriptive study.

Setting: PHC centres in the Spanish National Health System (SNHS).

Participants: Doctors and nurses who completed an online questionnaire which explored their alcohol intake, using the Alcohol Use Disorders Identification Test (AUDIT-C) alcohol assessment tool. The study population was recruited by random sampling stratified by regions of the SNHS PHC centres.

Primary and secondary outcome measures: Frequency of alcohol consumption, number of alcohol drinks on a typical day, frequency of more than six standard drinks (SDs) intake.

Results: A total of 1760 PHC providers completed the questionnaire. The frequency of alcohol consumption was: abstention (12%, 95% CI 10.4% to 13.5%); one or less SDs/month (26%, 95% CI 23.8% to 27.9%); 2-4 SDs/month (32.2%, 95% CI 29.7% to 34.1%); 2-3 SDs/week (17.9%, 95% CI 16.0% to 19.6%); four or more SDs/week (11.9%, 95% CI 10.3% to 13.3%). The number of drinks on a typical day was: none (45.6%, 95% CI 42.9% to 47.6%); 1-2 drinks (47.3%, 95% CI 23.8% to 27.9%); 3-4 drinks (6.5%, 95% CI 5.3% to 7.6%). The percentage of hazardous drinking, according to AUDIT-C criteria, was 32% (95% CI 26.7 to 37.3), with a greater frequency of intake in older professionals (p<0.001), in contrast to a higher number of drinks consumed on a typical day by younger providers (p<0.001). Intake was higher among males (p<0.001), primary care physicians (p<0.001) and resident trainers (p<0.001).

Conclusions: Our study discloses the most up-to-date portrait of current alcohol consumption among Spanish PHC providers, showing a higher prevalence of alcohol intake, compared with the general population. Preventive strategies should be implemented to improve the awareness and training of PHC professionals towards alcohol consumption.
