Toxicity awareness and unintended suicide in drug overdoses
1Accident and Emergency Department, Royal Victoria Hospital, Belfast.
Abstract:
The objective of this paper is to determine patients awareness of the toxicity of the drugs they overdose with, the source of these drugs, and whether they would have taken them had they been fully aware of their toxicity, and to examine the implications for prevention. A prospective review of one hundred consecutive overdoses admitted through an A&E department was carried out. Awareness was scored by a ranking questionnaire and intent by response to a standard question when toxicity was explained. Paracetamol was most the most frequently taken drug (39 cases). Overall awareness of toxicity was low. Twenty-eight patients (30%) said they would not have overdosed if they had been aware of the toxicity of what they had taken. Forty-nine per cent of patients took someone elses tablets. There is a rise in analgesic poisoning from 1976. Higher toxicity awareness may reduce the incidence of drug overdose. Smaller prescriptions and over the counter preparations especially paracetamol and limited access to toxic drugs, especially in high-risk homes, should reduce both the number and severity of overdoses. It is possible that a number of deaths from deliberate drug overdose may be unintentional as 30% of survivors in this study did not intend the toxic effects of the drug taken.
Insights
Patient awareness of drug toxicity is alarmingly low, with many overdoses potentially preventable if toxicity information was fully understood. Increased awareness could significantly reduce drug overdose incidents.
Area of Science:
- Toxicology
- Public Health
- Emergency Medicine
Background:
- Drug overdose remains a significant public health concern.
- Understanding patient awareness of drug toxicity is crucial for prevention strategies.
- Analgesic poisoning, particularly paracetamol, has shown a rising trend.
Purpose of the Study:
- To assess patient awareness of drug toxicity in overdose cases.
- To identify the sources of drugs used in overdoses.
- To evaluate the impact of toxicity awareness on overdose intent and prevention.
Main Methods:
- Prospective review of 100 consecutive overdose admissions.
- Utilized a ranking questionnaire to score patient awareness of drug toxicity.
- Assessed overdose intent through standard questions after explaining drug toxicity.
Main Results:
- Paracetamol was the most common drug involved in overdoses (39 cases).
- Overall awareness of drug toxicity was low among patients.
- 30% of patients stated they would not have overdosed if aware of the toxicity.
- 49% of patients obtained drugs from someone else's prescription.
- A significant portion of survivors (30%) did not intend the toxic effects of the drug taken.
Conclusions:
- Low awareness of drug toxicity contributes to the incidence of drug overdose.
- Enhanced patient education regarding drug toxicity may reduce overdose rates.
- Strategies like smaller prescriptions, restricted access to toxic medications (especially paracetamol), and limiting access in high-risk households could decrease overdose frequency and severity.
