Introducing safety syringes into a UK dental school--a controlled study

Area of Science:

• Dental medicine
• Occupational safety
• Public health

Background:

• A significant portion of sharps injuries in dentistry stem from non-disposable syringes, particularly during needle disposal.
• Needle-stick injuries pose a substantial risk to dental professionals, necessitating improved safety protocols.

Purpose of the Study:

• To evaluate the selection and implementation of safety syringes in a dental school setting.
• To assess the effectiveness of safety syringes in reducing needle-stick injuries.
• To analyze the associated costs and benefits of transitioning to safety syringes.

Main Methods:

• A dental school evaluated and introduced disposable safety syringes after comprehensive staff and student education.
• A control unit continued using non-disposable syringes for comparison.
• Data on needle-stick injuries were collected and analyzed over a two-year period.

Main Results:

• Avoidable needle-stick injuries decreased from 11.8 to 0 per 1,000,000 hours worked in the intervention group.
• The control group saw a reduction from 26 to 20 injuries per 1,000,000 hours worked.
• Safety syringes demonstrated comparable costs to non-disposable ones, with significant savings in injury management and psychological impact.

Conclusions:

• The transition to safety syringes is highly recommended for all dental professionals.
• Effective staff and student education is paramount for the successful implementation of safety syringe programs.
• Safety syringes offer a cost-effective solution for reducing occupational hazards in dentistry.
