The risks associated with preoperative alcohol misuse by patients  before undergoing total joint arthroplasty are not well known,  yet alcohol misuse by surgical patients is common and has been  linked to an increased risk of complications after other procedures.   
The purpose of this study was to evaluate the association between  a patient's preoperative standardized alcohol-misuse screening  score and his or her risk of complications after total joint  arthroplasty.
The Alcohol Use Disorders Identification  Test-Consumption (AUDIT-C) is an alcohol-misuse screening instrument  administered annually to all patients receiving care through the  Veterans Health Administration (VHA). The scores range from 0 to 12,  with higher scores signifying greater and more frequent consumption.  In a study of 185 male patients who had alcohol screening scores  recorded in the year preceding surgery at a Palo Alto VHA facility,  and who reported at least some alcohol use, we estimated the  association between preoperative screening scores and the number of  surgical complications in an age and comorbidity-adjusted regression  analyses.
Of the 185 patients reporting at least some drinking  in the year before their total joint replacement, 17%  (thirty-two) had an alcohol screening score suggestive of alcohol  misuse; six of those thirty-two patients had one complication,  four had two complications, and two had three complications. The  screening scores were significantly related to the number of  complications in a negative binomial regression analysis (exp[β]  = 1.29, p = 0.035), which demonstrated a 29% increase in the  expected number of complications with every additional point of  the screening score above 1, although with wide confidence intervals  for the higher scores.
