Emergency Departments

Risky Alcohol Use, Past Year, Emergency Department Attendees, Victoria and Vancouver, 2008-10

Hospital emergency departments (EDs) are ideal settings to identify and monitor emerging trends in risky patterns of alcohol and other substance use that increase the risk of injury, overdose or poisoning, and many of the acute harms caused by excessive substance use. Such acute effects contribute to the bulk of alcohol- and drug-caused deaths in Canada but are not systematically monitored. A great proportion of trauma is found in EDs where alcohol and other drugs have been shown as a major risk factor for injury.

This dataset contains information collected from surveys initiated in two BC sites, Vancouver General Hospital (VGH) in Vancouver and Royal Jubilee Hospital (RJH) in Victoria, designed to monitor patterns and trends among individuals presenting to Emergency Departments (EDs) late and night and in the early hours of the morning on weekends. This population was selected because it is known to have a high rate of prior psychoactive substance use contributing to injury or illness. The ability to monitor the proportion of ED patients who use or misuse substances, the characteristics of their substance use and related harms may therefore serve as an early warning system for substance problems in the greater population. To date, five waves of survey data collection (quantitative and qualitative) have been completed in both sites: 2008, 2009 (Wave 1 & 2) and 2010 (Wave 1 & 2). The first wave of data collection for 2011 is currently underway in both cities.

Self-Report Substance Use in the past 30 Days, Vancouver and Victoria
Nearly 85 percent of people attending the emergency room on a late weekend night in Vancouver reported having used alcohol in the thirty days previous to the onset of their illness or injury. Close to 91 percent of people attending the emergency room on a late weekend night in Victoria reported having used alcohol in the thirty days previous to the onset of their illness or injury.

Self-Report Substance Use in the 6 Hours Previous to Illness or Injury, Vancouver and Victoria
Nearly 15 percent of people attending the emergency room on a late weekend night in Vancouver reported having used alcohol in the six hours previous to the onset of their illness or injury. Close to 44 percent of people attending the emergency room on a late weekend night in Victoria reported having used alcohol in the six hours previous to the onset of their illness or injury.

Risky Substance Use (alcohol and other drugs) in the past Year, Vancouver and Victoria
The Emergency Department Monitoring study gathers data on risky and potentially harmful use of alcohol and other drugs reported by ED attendees in the past year. The data are compiled based on scores from two standardised tests incorporated into the survey instrument, the Alcohol Use Disorders Identification Test (AUDIT) and the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST).

Breathalyser and Drug Swab Test Results, Vancouver and Victoria
The Emergency Department Monitoring Study gathers information on recent alcohol and other drug use from ED attendees who are interviewed. This includes self-report data as well as saliva drug test (detects cannabis, opiates, amphetamines and cocaine) and blood alcohol content (breathalyzer) results regarding the 6 hour time period previous to their illness or injury.

Component Details

This emergency department study is one component of the BC Alcohol and Other Drug Monitoring Project. It is an ongoing emergency department study that is currently recruiting patients who come into the ED on one Friday and one Saturday evening per month between 9 p.m. and 4 a.m. at two EDs in British Columbia (Royal Jubilee Hospital in Victoria and Vancouver General Hospital in Vancouver). A pilot study was conducted on 97 patients early in 2008 to test the survey instruments and protocol. As a result, improvements were made to the sampling strategy, the survey instruments, the study protocol and the consent form.

Currently this monitoring study is using ICD-9 because one of our study sites is still using this version of the diagnostic categories in their emergency department. In addition, information obtained from patients in a busy ED is not specific enough to code for the more detailed ICD-10 conditions.

Inclusion Criteria

Interviewees who are between 17 to 75 years of age, can speak and understand English and can provide informed consent are asked to participate. Each respondent completes an interviewer-administered survey, a breathalyzer test and a saliva test for drugs of abuse.


Instruments

Patients who consent to be in the study are interviewed using a standardized survey instrument. The survey consists of questions pertaining to the reason for visit, the participant’s drug use history (lifetime use, past 12 months, one month, one week, and yesterday use), including specific alcohol use, cannabis use, and injection drug use. There are questions pertaining to drug-related harms and to alcohol or drug use in the six hours prior to onset of symptoms/injury. Survey instruments were developed for each site: Royal Jubilee Hospital and Vancouver General Hospital.

BAC and Saliva Tests

Participants also consent to a breathalyzer test and a saliva drug test. The breath test used is either the Alco-Sensor IV - Blue Dot or the Alco-Sensor IV FST breathalyzer. For the breathalyzer test, a subject blows into a sterile disposable mouthpiece for 5 to 10 seconds and the machine automatically estimates the BAC. A saliva/sweat drug test is administered, using a Securetec Detektions-Systeme AG Drugwipe5 five-drug sensing test strip. This is a self-contained testing strip which displays the presence of metabolites of drugs via the development of coloured lines in the strip's detection zone: amphetamine-like substances (including amphetamine, methamphetamine, ecstasy), cocaine, opiates (heroin and morphine) and cannabis.

Locations and Partnerships

Two locations are used for this study – Vancouver General Hospital (VGH) in Vancouver and Royal Jubilee Hospital (RJH) in Victoria. VGH is the largest hospital in British Columbia and the major tertiary referral centre for the province. Services in all adult areas of medicine except obstetrics are provided at this site. RJH is one of two tertiary hospitals serving Vancouver Island (Victoria General Hospital is the other). These hospitals operate as one large facility across two sites, providing high-level trauma care and specialized services.

Securing these locations has been made possible by having direct collaboration with key ED medical staff at each site. Drs. Andrew MacPherson at RJH and Jeff Brubacher at VGH have been instrumental in moving this project forward. Other possible sites for expansion include St. Paul’s Hospital in Vancouver and Victoria General Hospital as both sites have shown interest.

Approximately 1021 patients participated in between April 2008 and June 2010 (558 in Vancouver and 463 in Victoria). In Vancouver, roughly half (50.4%, n=281) of respondents identified as female and the majority identified as heterosexual (87.5, n=488). Vancouver respondents were predominately Caucasian (59.9%, n =334), and the next largest group identified as Chinese (10.8 %, n=60). Almost three quarters of the respondents were born in Canada (67.6%, n=377). Just over half of the respondents (55.2%, n=308) reporting having either full- or part-time employment and just under a quarter (19%, n=106) were attending full-time school (either college or university). The mean age of the sample was 37.5 years (range 17-75 years) and just over a quarter owned their own home (26.6, n= 123). In Victoria, just under half of respondents (47.3%, n=219) identified as female and the majority identified as heterosexual (87.7, n=406). Victoria respondents were predominately Caucasian (75.6%, n=350), followed by Aboriginal respondents (4.3 %, n=20). Around three quarters of the respondents were born in Canada (74.7%, n=346). Just under half of the respondents (43.8%, n=203) had either full- or part-time employment and just under a fifth (17.7%, n= 82) reported attending full-time school (either college or university). Mean age was 38.25 years (range 17-75 years) and just over a quarter owned their own home (26, n= 145).
