Patient-centered care interventions for the management of alcohol use disorders: a systematic review of randomized controlled trials.
OBJECTIVE
Patient-centered care (PCC) is increasingly accepted as an integral component of good health care, including addiction medicine. However, its implementation has been controversial in people with alcohol use disorders.


METHODS
A systematic search strategy was devised to find completed randomized controlled trials enrolling adults (>18 years) with alcohol use disorders. Studies had to use a PCC approach such that they should have been individualized, respectful to the patients' own goals, and empowering. Studies until September 2015 were searched using PubMed, Scopus, the Cochrane Library, PsychINFO, and Web of Knowledge.


RESULTS
In total, 40 studies enrolling 16,020 patients met the inclusion criteria. Assessment revealed two main categories of study: psychosocial (n=35 based on motivational interviewing) and pharmacological (n=5 based on an as needed dosing regimen). Psychosocial interventions were further classified according to the presence or absence of an active comparator. When no active comparator was present, studies were classified according to the number of sessions (≥1). Results from single sessions of motivational interviewing showed no clear benefit on alcohol consumption outcomes, with few studies indicating benefit of PCC versus control. Although the results for studies of multiple sessions of counseling were also mixed, many did show a significant benefit of the PCC intervention. By contrast, studies consistently demonstrated a benefit of pharmacologically supported PCC interventions, with most of the differences reaching statistical significance.


CONCLUSIONS
PCC-based interventions may be beneficial for reducing alcohol consumption in people with alcohol use disorders.
