Screening for alcoholism in general hospitals

Area of Science:

• Addiction Medicine
• Public Health
• Epidemiology

Background:

• Systematic screening at North Bay Psychiatric Hospital revealed a high prevalence of alcoholism (57%) among patients.
• This prevalence exceeded typical rates observed in mental health facilities, prompting an investigation into regional factors.
• The study questioned whether this high rate reflected general alcoholism prevalence in Northeastern Ontario or referral biases.

Purpose of the Study:

• To investigate the prevalence of alcohol-related problems in general hospitals in Northern Ontario.
• To compare these findings with those from general hospitals in Southern Ontario.
• To validate the effectiveness of systematic screening for alcohol use disorders.

Main Methods:

• Screening for alcohol-related problems using questionnaires and liver function tests in general hospital (medical and surgical) patients.
• Comparative analysis between Northern and Southern Ontario general hospitals using identical screening methods.
• Diagnostic confirmation using the Diagnostic Interview Schedule (revised) for positive screening cases.

Main Results:

• Northern Ontario general hospitals exhibited a higher prevalence of alcohol-related problems compared to Southern Ontario general hospitals.
• The regional difference in alcohol-related problems was more pronounced in higher social classes.
• A significant 83.5% of patients with positive screening results were confirmed to have alcohol abuse or dependence.

Conclusions:

• Systematic screening for alcoholism is crucial in general hospital settings.
• Alcohol-related problems are demonstrably more prevalent in Northern Ontario general hospitals compared to Southern Ontario.
• The study validates the utility of screening tools in identifying alcohol use disorders effectively.
