The correlates and extent of prescribing of medications for alcohol relapse prevention in England

Aims To determine the pattern and extent of prescribing of medications for alcohol relapse prevention (ARP) in England. Design Cross-sectional. Setting Specialist drug and alcohol treatment providers in England reporting to the National Drug Treatment Monitoring System. Participants Service users aged 18+, with alcohol the primary substance of dependence, completing a treatment journey between April 2013 and March 2016 (n = 188 152). Measurements Prescription of medications for ARP during a treatment journey. Data on service users' demographics, treatment and clinical characteristics were extracted. Findings The rate of prescribing medications for ARP was 2.1% in 2013/14, 6.8% in 2014/15 and 7.8% in 2015/16. A greater likelihood of prescription was associated with treatment journey year [2014/15; adjusted odds ratio (aOR) = 3.269, 95% confidence intervals (CI) = 3.044-3.510, 2015/16; aOR = 3.823, CI = 3.560-4.106], age (25-34; aOR = 1.622, CI = 1.380-1.907, 35-54; aOR = 1.901, CI = 1.628-2.220 or 55+; aOR = 1.700, CI = 1.446-1.999), female gender (aOR = 1.129, CI = 1.077-1.184), white ethnicity (aOR = 1.219, CI = 1.077-1.380), regional prevalence of alcohol dependence (middle rate; aOR = 1.121, CI = 1.024-1.228), severity of alcohol dependence (moderate dependence without complex needs; aOR = 1.329, CI = 1.244-1.419, severe dependence without complex needs; aOR = 1.308, CI = 1.188-1.441, moderate/severe dependence with complex needs; aOR = 1.131, CI = 1.020-1.255), treatment setting (inpatient; aOR = 10.512, CI = 9.950-11.104, primary care; aOR = 2.264, CI = 2.050-2.500, residential; aOR = 3.216, CI = 2.807-3.685), prior treatment for alcohol dependence (aOR = 1.242, CI = 1.183-1.304), longer treatment journey (aOR = 1.002, CI = 1.002-1.002), more drinking days in the prior 28 days (aOR = 1.021, CI = 1.018-1.024) and drinking a higher number of alcohol units in the prior 28 days (aOR = 1.002 CI = 1.001-1.004). Living in a region of England with the lowest alcohol prevalence was associated with a lower likelihood of prescription of medication for aRP (AOR = 0.491, CI = 0.436-0.552). Conclusions In England, medications for alcohol relapse prevention are rarely prescribed (e.g. 7.8% in 2015/16) and those prescriptions appear to be associated with specific service user demographics, treatment and clinical characteristics.
