Determinants of the underreporting of alcohol consumption by HIV/HCV co-infected patients during face-to-face medical interviews: the role of the physician.
OBJECTIVE
The objective of this study was to assess to what extent HIV/HCV co-infected patients underreport alcohol use to their physician with respect to self-reports from self-administered questionnaires (SAQ) and identify correlates of alcohol underreporting during face-to-face medical interviews (FMI).


METHODS
ANRS-CO13-HEPAVIH is a French multi-center cohort of HIV/HCV co-infected patients.


METHODS
Data were collected at enrolment using both SAQ and FMI while clinical data were retrieved from medical records. Alcohol consumption was assessed through SAQ and compared with FMI patient reports. Correlates of underreporting alcohol consumption during FMI with respect to SAQ were identified using logistic regression analysis.


RESULTS
Among 544 patients, 37% were classified as alcohol abusers according to AUDIT-C in the SAQ. During FMI, 14% underreported alcohol consumption. The following correlates were independently associated with underreporting alcohol consumption in FMI: not receiving HIV treatment, being followed up by a hepatologist for HCV infection and reporting a history of injecting drug use.


CONCLUSIONS
These results highlight the difficulties in alcohol consumption assessment which HCV specialists may face when suggesting to their HIV/HCV co-infected patients that they cease drinking completely. Patient awareness about the real need to reduce their alcohol use before starting HCV therapy may also contribute to underreporting. Innovative strategies for alcohol risk-reduction, including the promotion of controlled consumption and access to multidisciplinary teams, should be implemented for HIV/HCV co-infected patients in order to reduce barriers to HCV treatment.
